2、根據(jù)第一條的說(shuō)明，自動(dòng)餃子成型機(jī)的特征在于，所述傳送
面團(tuán)的傳輸裝置包括兩個(gè)相對(duì)地布置的輪子，使得輸出的餃皮厚度保持恒定。
3、根據(jù)第一條的說(shuō)明，自動(dòng)餃子成型機(jī)中的旋轉(zhuǎn)輪具有鋸齒表面。而且面粉容器中有攪拌器，用于攪拌其內(nèi)的面粉和積累在上述旋轉(zhuǎn)輪鋸齒表面的面粉。這樣當(dāng)積累在鋸齒表面的面粉隨著齒輪旋轉(zhuǎn)后就給面團(tuán)施加了一層面粉。
4、根據(jù)第一條的說(shuō)明，自動(dòng)餃子成型機(jī)中的填料控制器包括兩個(gè)相向的相互嚙合的滾軸，把填料控制器分成上下兩部分，因此當(dāng)兩個(gè)滾軸相對(duì)彼此旋轉(zhuǎn)時(shí)，定量的餡料就從控制器的上部進(jìn)入到控制器的下部。
5、根據(jù)第一條的說(shuō)明，自動(dòng)餃子成型機(jī)中的填料裝置包含有接餡料的導(dǎo)管和可垂直移動(dòng)的供料桿，所述導(dǎo)管與一個(gè)固定的支撐物相連接，供料桿與垂直滑動(dòng)板相連接，由此以垂直方向運(yùn)動(dòng)的方式把餡料放入餃皮中。
6、在對(duì)第五條填料裝置的描述中，與供料桿接觸的有爪形除料劑，與供料桿相關(guān)的垂直運(yùn)動(dòng)能進(jìn)一步完全去除粘附在供料桿上的餡料。
7、根據(jù)第一條的說(shuō)明自動(dòng)餃子成型機(jī)中的餃子成型設(shè)備由一個(gè)固定的下模和一個(gè)可轉(zhuǎn)動(dòng)的上模組成，該下模和上模沿一側(cè)鎖定在一起，上模相對(duì)于另一側(cè)上的軸轉(zhuǎn)動(dòng)180度。這就使得自動(dòng)餃子機(jī)一個(gè)凸起的下?？梢跃o密地夾進(jìn)到相應(yīng)的凹槽，以便把面團(tuán)折疊和切割到理想的形狀
8、根據(jù)第一條說(shuō)明，自動(dòng)餃子成型機(jī)中的兩個(gè)多邊形形狀的旋轉(zhuǎn)輪基本上是由兩個(gè)同步的八角形輪與保護(hù)套筒安裝在兩者之間以便用于防止面粉落入旋轉(zhuǎn)輪的軸上，一組八個(gè)餃子成型設(shè)備安裝在八角形輪的外圍。
9、根據(jù)第一條說(shuō)明，自動(dòng)餃子成型機(jī)中的推桿連接到楔形塊上，并且由其驅(qū)動(dòng)垂直滑落到多邊形旋轉(zhuǎn)輪固定軸上的楔形槽內(nèi)。
10、一個(gè)自動(dòng)餃子成型機(jī)實(shí)質(zhì)上由一個(gè)面團(tuán)筒控制面團(tuán)使用；一個(gè)傳動(dòng)裝置傳輸面團(tuán);一個(gè)面粉容器盛放面粉用于做面團(tuán)；一個(gè)餡料斗用于存儲(chǔ)餡料;填料控制裝置控制放入餃皮的餡的量；填料供給裝置負(fù)責(zé)把餡放入餃皮；,一個(gè)敲打裝置用來(lái)敲打餃皮的中央部分，形成一個(gè)凹痕，接收餡料;兩個(gè)多邊形旋轉(zhuǎn)輪子；多數(shù)餃子成型設(shè)備安裝在上述兩個(gè)多邊形旋轉(zhuǎn)輪外圍表面，便于把餃皮包起來(lái)形成餃子；一個(gè)推桿把做好的餃子推出成型裝置；一個(gè)固定和可移動(dòng)的電刷用來(lái)清潔餃子成型裝置；一個(gè)餃子收集器和面團(tuán)收集器分別負(fù)責(zé)收集做好的餃子和剩下的面團(tuán)，其中傳動(dòng)裝置傳送每個(gè)面團(tuán)到其中一個(gè)餃子成型器，敲打裝置敲打餃皮形成一個(gè)中間的凹痕，通過(guò)餡料控制器，餡料從餡料斗進(jìn)入凹痕，接著成型設(shè)備把餃皮折起來(lái)，裁剪成理想的相同大小和形狀，上述裝料裝置包括一個(gè)填料導(dǎo)管，其中送料裝置包括一個(gè)填料導(dǎo)管接收填料，和一個(gè)垂直可動(dòng)進(jìn)料桿,上述導(dǎo)管連接到一個(gè)固定的支撐，進(jìn)料桿連接一個(gè)垂直可滑動(dòng)的板，隨其傳送形成一個(gè)垂直運(yùn)動(dòng)，把餡放入面團(tuán)，可滑動(dòng)板的垂直滑塊運(yùn)動(dòng)受到一個(gè)半圓形滾筒和一個(gè)半圓形槽的影響，半圓形滾筒從有個(gè)輪的板那里產(chǎn)生一個(gè)銷，從那里產(chǎn)生一個(gè)半圓形槽，當(dāng)栓與槽齒合在一起時(shí)，轉(zhuǎn)動(dòng)的滾筒接觸到剛脫離板影響的輪子，當(dāng)栓與槽分離時(shí)，板繼續(xù)傳送隨其進(jìn)入垂直運(yùn)動(dòng)。
說(shuō)明
該項(xiàng)發(fā)明的背景
本發(fā)明涉及一種全自動(dòng)餃子機(jī)。
餃子是一種非常受歡迎的中國(guó)食物。包餃子的傳統(tǒng)方式是首先用手把適量的餡放在一塊面團(tuán)上，再把面團(tuán)捏到合適的大小或形狀,最后把面團(tuán)包起來(lái)形成一個(gè)餃子。用這種方法做成的餃子可能會(huì)不盡如人意，要么變得太大要么太小,因?yàn)楹茈y控制放入的餡的量,餃皮的厚度也不是固定的。此外,傳統(tǒng)的手工包餃子是不衛(wèi)生的，效率也不高。比如，它可能需要半個(gè)小時(shí)左右才能包好兩份餃子。隨著餃子需求量的快速增長(zhǎng),的確非常需要一個(gè)自動(dòng)餃子成型機(jī)。
總結(jié)該發(fā)明
本發(fā)明的主要目的是提供一個(gè)自動(dòng)餃子成型機(jī)，自動(dòng)執(zhí)行做好一個(gè)餃子必須完成的一系列操作，如傳送面團(tuán)，填充餡料，切割及折疊餃皮，以及餃子成品輸送等。
本發(fā)明的另一個(gè)目的是提供一個(gè)易于控制餃皮厚度和放入餡的量的自動(dòng)餃子成型機(jī)。
本發(fā)明還有一個(gè)目的，即提供一個(gè)緊湊的自動(dòng)餃子成型機(jī)，高效，衛(wèi)生，耗能少。
本發(fā)明的其他目的和優(yōu)勢(shì)將在以下詳細(xì)描述本發(fā)明的參照?qǐng)D紙中變得明顯。

詳細(xì)說(shuō)明
圖一和圖二根據(jù)本發(fā)明分別展示了自動(dòng)餃子成型機(jī)的前視圖。自動(dòng)餃子成型機(jī)大體上包含以下幾部分：一個(gè)固定餃皮的餃皮固定器一個(gè)傳輸餃皮的傳輸裝置一個(gè)把面粉施加在餃子皮上的面粉容器一個(gè)儲(chǔ)存餡料之后通過(guò)餡料控制器分送到填料裝置的餡料料斗一個(gè)把餃子皮切割成理想的形狀和大小的切割裝置一個(gè)通過(guò)壓餃皮的中央部分形成凹痕以包裹餡料的擠壓裝置一個(gè)在餡料包裹在餃皮內(nèi)后推動(dòng)餃子成型裝置折疊餃皮形成一個(gè)餃子的壓輪一個(gè)連接到餃子成型裝置推動(dòng)包好的餃子出該設(shè)備進(jìn)入餃子收集器的推桿每個(gè)餃子完成后就清掃一次餃子成型設(shè)備的固定刷和活動(dòng)刷一個(gè)收集剩下餃皮的餃皮收集器。
參考圖二展示了自動(dòng)餃子成型機(jī)制作餃子的過(guò)程。存儲(chǔ)在餃皮固定器中的餃皮通過(guò)傳輸裝置的兩個(gè)輪子和圍板傳輸?shù)矫娣廴萜?，兩個(gè)輪子相對(duì)的布置，使得餃皮的厚度保持恒定。面粉容器中有一個(gè)攪拌器攪拌容器中的面粉。輪子表面呈鋸齒狀，輪子與其相對(duì)布置。當(dāng)餃皮經(jīng)過(guò)旋轉(zhuǎn)輪和之間的空隙時(shí)，該設(shè)備就會(huì)在餃皮的背面施加定量的面粉以防止之后輸送過(guò)來(lái)的餃皮粘附在餃子成型裝置上。餃皮從面粉容器中出來(lái)之后就被輸送到了餃子成型裝置，然后擠壓裝置用其擴(kuò)展出的一端壓餃皮的中間部分形成凹痕來(lái)包裹餡料，同時(shí)切割裝置把餃皮切割成理想的形狀。餡料控制器把定量的餡料從餡料料斗中填入餃皮的凹痕處，然后壓輪使得餃子成型裝置折疊餃皮形成一個(gè)餃子。然后餃子通過(guò)推桿出餃子成型裝置進(jìn)入到餃子收集器中。兩個(gè)刷子清掃餃子成型裝置，然后該裝置就開(kāi)始接收下一個(gè)餃皮。這樣的一個(gè)過(guò)程一直重復(fù)，直到所有的餃皮固定器上的餃皮完盡。就目前的發(fā)明情況來(lái)看，現(xiàn)有一套含八個(gè)相同餃子成型裝置的設(shè)備，該設(shè)備今后會(huì)把包餃子的過(guò)程做的更為細(xì)致。
圖二中，餡料料斗中的螺旋給料機(jī)能持續(xù)的把餡料推到料斗的下方。如圖二所示，餡料控制器中裝有兩個(gè)滾軸，因此當(dāng)兩個(gè)滾軸以預(yù)定的角度旋轉(zhuǎn)時(shí)，聚集在餡料控制器上面的餡料就被擠壓到餡料控制器的下方，然后餡料通過(guò)導(dǎo)管進(jìn)入到填料裝置。
圖三展示了本發(fā)明填料裝置的分解透視圖。填料裝置通過(guò)第一個(gè)支撐與餃子成型裝置緊密相連，支撐物的一端有一個(gè)鐵環(huán)以便填料導(dǎo)管和供料桿插入。供料桿通過(guò)環(huán)形螺母與第二個(gè)支撐物的一端相連，第二個(gè)支撐物的另外一端固定在垂直滑板上（圖一所示），因此可以形成垂直運(yùn)動(dòng)。以這種方式供料桿能夠上下運(yùn)動(dòng)即推動(dòng)定量的餡料通過(guò)填料導(dǎo)管從餡料料斗中進(jìn)入到餃皮的凹痕處。
為了完全去除粘附在供料桿上的餡料，在供料裝置中裝有桶形餡料去除器，把其細(xì)長(zhǎng)的爪形臂裝在鐵環(huán)外圍預(yù)先制定的凹槽內(nèi)。臂的一端彎曲度落在滑板上靠螺絲釘與第二個(gè)支撐物連在一起。通過(guò)這種方式，活動(dòng)金屬板帶動(dòng)金屬板與桶形餡料去除器一起做垂直運(yùn)動(dòng)。彈簧裝置能夠進(jìn)一步加速餡料去除器向下運(yùn)動(dòng)的速度。
圖四是餃子成型裝置的分解透視圖。餃子成型裝置有兩個(gè)模具，一個(gè)固定的下模和一個(gè)可旋轉(zhuǎn)的上模。上模通過(guò)滾柱軸承與餃子成型裝置的側(cè)面相連，繞著軸的一側(cè)旋轉(zhuǎn)。上模和下模通過(guò)螺絲釘緊密的連在一側(cè)，上模和下模整體與兩個(gè)八角轉(zhuǎn)動(dòng)輪相連，這將在圖九和圖十中具體說(shuō)明。
上模的一個(gè)軸由帶臂的傳動(dòng)裝置帶動(dòng)。通過(guò)這種方式，上模繞著軸做180度旋轉(zhuǎn)，這樣下模凸出的地方就恰當(dāng)?shù)膴A進(jìn)到旋轉(zhuǎn)上模的凹陷處。這個(gè)過(guò)程相當(dāng)于折疊餃子皮的操作，同時(shí)由于凸起的快進(jìn)入凹陷處，餃子皮被切割成理想的形狀和大小。
一個(gè)餃子包好后下個(gè)餃子進(jìn)入餃子成型裝置前，該裝置就會(huì)被清潔一次。像前面圖二提到的那樣，固定刷用于清潔餃子成型裝置的表面，活動(dòng)刷用于進(jìn)一步清潔凹痕和凸起的塊。圖五描述了活動(dòng)刷的分解透視圖。其中刷毛與一端插在兩個(gè)金屬板之間的環(huán)形槽中的柄相連。叉子的一端固定在座位上，另一端插入環(huán)形槽用于驅(qū)動(dòng)活動(dòng)刷。叉安裝有臂和一個(gè)輪子，輪與軸上的凸輪一起運(yùn)動(dòng)，這樣當(dāng)凸輪的凸起部觸碰到，叉就會(huì)被迫轉(zhuǎn)動(dòng)到一端，從而推動(dòng)柄退向另一端。通過(guò)這種方式活動(dòng)刷可以反復(fù)旋轉(zhuǎn)與餃子成型裝置的旋轉(zhuǎn)輪相互配合一起轉(zhuǎn)動(dòng)來(lái)清潔凸起的地方和凹痕。彈簧連接在叉的兩個(gè)螺旋體和之間，叉上的螺旋體與軸分別驅(qū)動(dòng)活動(dòng)刷向前。
圖六是旋轉(zhuǎn)輪控制栓的分解透視圖。旋轉(zhuǎn)輪控制栓安裝在餃子成型裝置上由帶螺旋體的桿驅(qū)動(dòng)，該操作過(guò)程是通過(guò)桿的支點(diǎn)實(shí)現(xiàn)的。旋轉(zhuǎn)輪控制栓的前端呈叉狀，其由連接在桿上端的推桿驅(qū)動(dòng)。桿的下端彎曲呈臂狀.，并裝有一個(gè)輪。
圖五所示的輪與凸輪相互配合這樣當(dāng)凸輪的凸起部分觸碰到輪，就會(huì)推動(dòng)桿向逆時(shí)針?lè)较蛐D(zhuǎn)，由此推動(dòng)控制栓通過(guò)推桿做橫向運(yùn)動(dòng)。彈簧的作用在于使桿回歸到最初的位置。
垂直滑板通過(guò)本發(fā)明所涉及的特殊傳輸裝置實(shí)現(xiàn)垂直滑動(dòng)。圖七和圖八分別展示了傳輸裝置的分解視圖和垂直剖面圖。呈半圓狀的滾筒裝有栓，該栓位于半圓形滾筒的外圍和凸起部的中間，栓與金屬板上的半圓形槽銜接。齒輪通過(guò)另一個(gè)栓固定在滾筒軸的一端。金屬板上還裝有一個(gè)小的輪，該輪圍繞著自身的周旋轉(zhuǎn)。圖一所示的金屬板上安裝的相連的桿，用于在金屬板垂直滑動(dòng)時(shí)帶動(dòng)垂直滑板從而做垂直運(yùn)動(dòng)。金屬板的垂直滑動(dòng)可以通過(guò)滾筒和半圓形槽的相互配合得以實(shí)現(xiàn)。在滾筒上的栓銜接到半圓形槽時(shí)，輪就會(huì)觸碰到滾的表面。因此，盡管滾筒在轉(zhuǎn)動(dòng)但是金屬板依舊不會(huì)動(dòng)。在栓到達(dá)半圓形槽的左端之后，栓隨著滾筒的旋轉(zhuǎn)持續(xù)向下迫使金屬板向下，在達(dá)到最低位置后栓和金屬板然后被一起抬上去，最后再次與半圓形槽銜接，在達(dá)到最高點(diǎn)時(shí)金屬板會(huì)被控制停留一端時(shí)間。之后不斷重復(fù)這樣的一個(gè)過(guò)程。特別強(qiáng)調(diào)的是金屬板停留的時(shí)間相當(dāng)于從一個(gè)旋轉(zhuǎn)輪上的成型裝置到另一個(gè)裝置的時(shí)間。上述整個(gè)過(guò)程所需的時(shí)間能夠通過(guò)調(diào)整齒輪的旋轉(zhuǎn)速度來(lái)控制。切割裝置和填料桿的操作也能夠很容易的得到控制。
圖九和圖十詳細(xì)描述了餃子成型裝置的八角旋轉(zhuǎn)輪即旋轉(zhuǎn)輪和旋轉(zhuǎn)輪的軸與軸承的一端相連，滾軸和軸上的傳輸裝置通過(guò)螺母相連。在餃子成型機(jī)后面的齒輪外殼都配有上述裝置，也就是說(shuō)上述裝置位于齒輪防護(hù)外殼的后方。軸和齒輪防護(hù)外殼的前方安裝有兩個(gè)通過(guò)螺絲釘和連在一起的凸輪，還有八角輪和輪。螺絲釘用于把輪固定在軸的一端。八角輪與八角輪同時(shí)運(yùn)行，兩者都安裝在餃子成型裝置的前方。在下方打開(kāi)的水平保護(hù)套管連接在兩個(gè)輪和之間，這樣是為了防止餃皮上的面粉落入兩個(gè)旋轉(zhuǎn)輪的軸上，裝有固定軸的八角輪的表面有楔形槽。一套餃子成型裝置鑲嵌在八個(gè)八角輪和的外圍表面。垂直滑動(dòng)的楔塊嵌在固定軸的楔形槽內(nèi)。當(dāng)輪轉(zhuǎn)動(dòng)時(shí)楔形塊水平桿槽內(nèi)的栓滑動(dòng)，從而導(dǎo)致槽中楔形塊垂直滑動(dòng)。楔形塊垂直滑動(dòng)是為了推動(dòng)完成的餃子出餃子成型裝置進(jìn)入到餃子收集器中，這個(gè)過(guò)程是依靠推桿（圖二所示）與臂的連接實(shí)現(xiàn)的。需要明白的是旋轉(zhuǎn)輪的八角形狀只是目前發(fā)明的最好的體現(xiàn)，而且基本上相當(dāng)數(shù)量的餃子成型裝置所裝有的任何多邊形旋轉(zhuǎn)輪都能夠被改裝。
根據(jù)目前的自動(dòng)包餃子機(jī)來(lái)看，這種發(fā)明是很高效的，因?yàn)椴僮鬟@臺(tái)機(jī)器的能量大約只需要1HP，并且比起工人來(lái)，機(jī)器可以更衛(wèi)生更快的包餃子。機(jī)器體積很小巧，可以把它很容易地移動(dòng)到任何方便的地方。

Description
BACKGROUND OF THE INVENTION
The present invention relates to an automatic dumpling making machine.
Dumpling is a very popular Chinese food. Traditional way of making dumplings is to first manually put a proper amount of stuffings on a piece of dough sheet, then cut the sheet into a suitable size or shape, and finally fold the sheet up to form a dumpling. Dumplings produced in this way may undesirably become too large or too small because the amount of stuffings to be put in is difficult to control, and the thickness of the dough sheets is not constant. Furthermore, the traditional way of making dumplings by hands is unsanitary and inefficient. It may take, for instance, half an hour or so to complete dumplings for a serving of two. With the fast growing demand for dumplings, an automatic dumpling making machine is indeed in great need.
SUMMARY OF THE INVENTION
The primary object of the present invention is to provide an automatic dumpling making machine wherein a series of operations required to complete a dumpling such as dough sheets delivery, stuffings feeding, dough sheets cutting and folding, and dumpling product removing etc. are performed automatically.
Another object of the present invention is to provide an automatic dumpling making machine wherein the thickness of dough sheets and the amount of stuffings to be fed in can be readily controlled.
Still another object of the present invention is to provide a compact automatic dumpling making machine which is efficient and sanitary in making dumplings and consumes very little power.
Other objects and advantages will become apparant from the following detailed description of the present invention with reference to the accompanying drawings.

DESCRIPTION OF PREFERRED EMBODIMENT
FIGS. 1 and 2 show respectively the perspective and the front views of the automatic dumpling making machine according to the present invention. The automatic dumpling making machine 10 substantially comprises a dough sheets holder 11 for holding dough sheets to be used; a transmission mechanism 12 for transmitting dough sheets; a flour container 13 for containing flour to be applied over the dough sheets; a stuffing hopper 14 for storing stuffings and later dispensing them through a stuffing controller 15 to a stuffing feeding device 16; a cutting device 17 for cutting the dough sheets into a proper shape and size; a hitting device 18 for hitting the central part of the dough sheet to form a dent for receiving stuffings; a pressing wheel 19 for forcing a dumpling forming device 20 to fold up the dough sheet after stuffings have been fed into the sheet to form a dumpling; a pushing rod 21 connected to the forming device 20 for pushing the finished dumplings out of the forming device into a dumpling collector 24; a fixed brush 22 and a movable brush 23 for cleaning the forming device 20 everytime after a dumpling is completed; and a dough sheet collector 25 for collecting the remaining dough sheets.
The process of making dumplings by means of the automatic dumpling making machine 10 is described below with reference to FIG. 2. The dough sheets stored in the holder 11 are transmitted through a pair of wheels 121 and 122 of the transmission mechanism 12 and a confining plate 26 into the flour container 13. The wheels 121 and 122 are oppositely arranged so that the thickness of the dough sheets passing therethrough is made constant. Provided in the flour container 13 are a stirrer 131 for stirring the flour in the container, a wheel 132 having a zigzagged outer surface, and a wheel 133 located opposite to the wheel 132. When a dough sheet passes through the space between the two wheels 132 and 133, a proper amount of flour will be applied over the back surface of the dough sheet for preventing the same from sticking to the dumpling forming device 20 later. After exiting from the flour container 13, the dough sheet is placed on the forming device 20. The hitting device 18 then hits with its one enlarged end 181 the central part of the sheet to form a dent for filling in stuffings. In the meantime, the cutting device 17 cuts the dough sheet into a proper shape. A fixed amount of stuffings is fed from the hopper 14 through the amount controller 15 into the dent on the sheet. The pressing wheel 19 then forced the forming device 20 to fold up the dough sheet to form a dumpling. The dumpling is then pushed by the pushing rod 21 out of the forming device into the dumpling collector 24. The forming device 20 is cleaned by brushes 22 and 23, and is then ready for receiving the next sheet. This process repeats until all the dough sheets in the holder 11 are used up. According to the present invention, there is a set of eight identical forming devices which are to be detailed later.
Referring to FIG. 2, a screw feeder 141 is provided in the stuffing hopper 14 for constantly driving the stuffings downward. Two rollers 151 and 152 shaped as illustrated in FIG. 2 are provided in the stuffing controller 15 so that when the two rollers rotate through a predetermined angle the stuffings accumulated in the upper part 153 of the controller are squeezed into the lower part 154 of the same and then enter the feeding device 16 through a guide tube 155.
FIG. 3 shows an exploded perspective view of the feeding device 16 according to the present invention. The feeding device 16 is secured through a first support 161 to the outer surfa
