Forming mechanism is the main mechanism of disposable corn starch tableware mold, which determines the product performance in some aspects, so the selection of forming mechanism is very important. The following is the shape selection analysis of each part of the device:

　　1. 脫模機(jī)構(gòu)的選擇:

　　1. Selection of demoulding mechanism:

　　主要有兩種驅(qū)動(dòng)機(jī)構(gòu)，即氣缸驅(qū)動(dòng)或氣缸驅(qū)動(dòng)，為了方便成型機(jī)各機(jī)構(gòu)的有益合作，建議采用氣缸驅(qū)動(dòng)。

　　There are mainly two kinds of driving mechanisms, namely cylinder driving or cylinder driving. In order to facilitate the beneficial cooperation of various mechanisms of the molding machine, it is recommended to use cylinder driving.

　　2. 加煤機(jī)構(gòu):

　　2. Coal feeding mechanism:

　　送料機(jī)構(gòu)主要有兩種類型:

　　There are two main types of feeding mechanism:

　　(1)稱重送料機(jī)構(gòu):

　　(1) Weighing and feeding mechanism:

　　稱重送料機(jī)構(gòu)是將一定重量的材料送入模具，其優(yōu)點(diǎn)是可以獲得準(zhǔn)確的送料量，缺點(diǎn)是需要復(fù)雜的機(jī)械和電子機(jī)構(gòu)，從而增加了機(jī)構(gòu)的成本。

　　Weighing and feeding mechanism is to send a certain weight of materials into the mold. Its advantage is that it can obtain accurate feeding amount, but its disadvantage is that it needs complex mechanical and electronic mechanisms, thus increasing the cost of the mechanism.

　　(2)定容進(jìn)給機(jī)構(gòu):

　　(2) Constant volume feeding mechanism:

　　恒容送料機(jī)構(gòu)是將一定量的材料送入模具，其優(yōu)點(diǎn)是簡(jiǎn)單，成本低，缺點(diǎn)是更難得到準(zhǔn)確的送料量。

　　Constant volume feeding mechanism is to send a certain amount of materials into the mold, which has the advantages of simplicity, low cost and more difficult to get accurate feeding amount.

　　由于介質(zhì)板所需要的材料并不十分準(zhǔn)確，允許存在一定的誤差，因此提出了定容送料機(jī)構(gòu)。

　　Because the material needed for the medium plate is not very accurate and some errors are allowed, a constant volume feeding mechanism is proposed.

　　3.材料共享機(jī)制:

　　3. Material sharing mechanism:

　　一次性餐具推模機(jī)構(gòu)的功能是在加壓前，利用上模具的旋轉(zhuǎn)將物料推離，保證壁厚均勻。提出采用液壓馬達(dá)驅(qū)動(dòng)方式。

　　The function of pushing die mechanism of disposable tableware is to push materials away by using the rotation of upper die before pressurization, so as to ensure uniform wall thickness. The hydraulic motor driving mode is proposed.

　　4. 回轉(zhuǎn)機(jī)構(gòu):

　　4. Slewing mechanism:

　　輸送機(jī)構(gòu)的作用是輸送站，主要有以下幾種方式:

　　The function of the conveying mechanism is the conveying station, mainly in the following ways:

　　(1)輪槽間歇機(jī)構(gòu):

　　(1) Wheel groove intermittent mechanism:

　　該方法具有結(jié)構(gòu)簡(jiǎn)單、沖擊大、加工精度高、只適用于小功率場(chǎng)合的優(yōu)點(diǎn)

　　This method has the advantages of simple structure, large impact, high machining accuracy and is only suitable for small power occasions

　　(2)棘輪棘爪間歇機(jī)構(gòu):

　　(2) Intermittent mechanism of ratchet and pawl:

　　棘輪棘爪間歇機(jī)構(gòu)是一種常見(jiàn)的傳動(dòng)機(jī)構(gòu)

　　The intermittent mechanism of ratchet and pawl is a common driving mechanism

　　(3)齒輪和齒環(huán)傳動(dòng):

　　(3) Gear and ring gear drive:

　　齒環(huán)傳動(dòng)是工程機(jī)械中常用的傳動(dòng)方式。

　　Gear ring transmission is a common transmission method in construction machinery.

　　(4)小齒輪和銷齒輪傳動(dòng):

　　(4) Pinion and pin gear drive:

　　齒輪-銷齒傳動(dòng)是各種齒輪驅(qū)動(dòng),因?yàn)殇N輪牙是一個(gè)圓形銷,與一般的裝置相比,結(jié)構(gòu)簡(jiǎn)單,加工容易,成本,容易維修和其他的優(yōu)勢(shì),所以它是用來(lái)代替漸開(kāi)線齒輪的尺寸大一點(diǎn),有一個(gè)更大的好。齒輪-齒輪環(huán)傳動(dòng)比較適合在注塑機(jī)上使用。

　　Gear pin gear drive is a kind of gear drive, because the pin gear tooth is a round pin, compared with the general device, it has the advantages of simple structure, easy processing, cost, easy maintenance and other advantages, so it is used to replace the involute gear with a larger size and a better one. Gear ring transmission is suitable for injection molding machine.

　　通過(guò)對(duì)上述方案的比較，確定一次性玉米淀粉餐具模具的旋轉(zhuǎn)機(jī)構(gòu)采用齒輪-銷齒傳動(dòng)。

　　Through the comparison of the above schemes, it is determined that the rotation mechanism of the disposable corn starch tableware mould is driven by gear pin teeth.
