一次性（xìng）玉米澱粉餐具模具結構形狀的選擇

　　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. 脫模機構的選擇:

　　1. Selection of demoulding mechanism:

　　主（zhǔ）要有兩種驅動機構，即氣缸驅動或（huò）氣缸驅動，為了方便成型機各機構的有益合作，建議采用氣缸（gāng）驅動。

　　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. 加煤機構:

　　2. Coal feeding mechanism:

　　送料機構主要有兩種類（lèi）型:

　　There are two main types of feeding mechanism:

　　(1)稱重（chóng）送料機構:

　　(1) Weighing and feeding mechanism:

　　稱重送料機構（gòu）是將一定重量的材料送入模具（jù），其優點是可以獲得準（zhǔn）確的送料量，缺點是（shì）需要複雜的機械和電子機構，從而增加了機（jī）構的成（chéng）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)定容進給機構:

　　(2) Constant volume feeding mechanism:

　　恒容送料機構是將一（yī）定量的材料送入模具，其（qí）優點是簡單，成本（běn）低（dī），缺點是更難得到準確的送料量。

　　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.

　　由於介質板所需（xū）要的材料並不十分準確，允許存在（zài）一定的（de）誤差（chà），因此提出了定容送料機構。

　　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.材料共享機製:

　　3. Material sharing mechanism:

　　一次性（xìng）餐具推模機構的功能是在加（jiā）壓（yā）前（qián），利（lì）用上模具的旋轉將物料推離，保證壁厚均勻。提出采用（yòng）液壓馬達（dá）驅動方式。

　　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. 回轉機構:

　　4. Slewing mechanism:

　　輸送機構的作用是輸送站，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:

　　(1) Wheel groove intermittent mechanism:

　　該方法具有結構簡單、衝擊大、加（jiā）工精度高（gāo）、隻適用於小功率（lǜ）場（chǎng）合（hé）的優點

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

　　(2)棘輪棘爪間歇機構:

　　(2) Intermittent mechanism of ratchet and pawl:

　　棘輪棘爪間（jiān）歇機構是（shì）一種常見的傳動機構

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

　　(3)齒輪和齒環傳動:

　　(3) Gear and ring gear drive:

　　齒環傳動是工程機械中常用的傳動方式（shì）。

　　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-銷齒傳動是各種齒輪驅動,因為銷輪牙是一個圓形銷,與一般的裝置相比（bǐ）,結構簡單（dān）,加工（gōng）容易,成本,容易（yì）維修和其他的優（yōu）勢,所以它是用來代替漸（jiàn）開線齒輪的尺寸大（dà）一點,有一個更（gèng）大的好。齒輪（lún）-齒輪環傳動比較適合在注塑機上使用。

　　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.

　　通過對上述方案的比較，確定一（yī）次性玉米澱粉餐具模具的旋轉機構采用齒輪-銷齒傳動。

　　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.
