In the design of the disposable tableware molding machine, the diversity of its functions is fully considered. By changing the mold, all kinds of tableware such as bowls, plates, boxes can be produced, and the multi-function of one machine can be realized.

模具的設(shè)計不但要考慮木身的功能，還要考慮美學(xué)原理和人機工程學(xué)的原理。經(jīng)過觀察各酒店、餐館和小吃店，采用統(tǒng)計方法確定中盤的尺寸。

Not only the function of wood body, but also the principle of aesthetics and ergonomics should be considered in the design of mold. After observing the hotels, restaurants and snack bars, the size of the medium plate was determined by statistical method.

壓制力的確定：

Determination of pressing force:

壓制力的大小一方面決定了餐具產(chǎn)品的密實度，另一方面也決定了一次性餐具設(shè)備成型機的大小，壓制力越大，餐具也密實，強度越高，但壓制力越大，一次成型的餐具越多，成型機體積就越大，機身越笨重。因此壓制力的大小和一次成型的餐具的數(shù)量應(yīng)選擇大小適中。

On the one hand, the size of pressing force determines the compactness of tableware products, on the other hand, it also determines the size of disposable tableware equipment molding machine. The greater the pressing force is, the denser the tableware is, the higher the strength is. However, the greater the pressing force is, the more tableware is formed at one time, and the molding machine volume is larger and the body is more bulky. Therefore, the size of pressing force and the number of tableware should be selected to be moderate.

1、壓制應(yīng)力的確定：

1. Determination of pressing stress:

壓制應(yīng)力的大小決定了餐具的密實度。在沒有規(guī)范或其它參考時，可以參照文獻[機械設(shè)計手冊]中木材的抗壓強度來考慮。參照木材的物理力學(xué)特性，用木材的抗壓強度限度作為參照值。木材的強度限度變化范圍比較大，是不同木材的強度不同，二是不同的受力方向強度也不同，順紋抗壓強度都比較高，而橫向格外是弦向強度比較低。

The compactness of tableware is determined by the size of pressing stress. In the absence of specifications or other references, the compressive strength of wood in the literature [mechanical design manual] can be considered. According to the physical and mechanical properties of wood, the compressive strength limit of wood is used as the reference value. The variation range of strength limit of wood is relatively large, the strength of different wood is different, the strength of different stress direction is also different, the compressive strength along the grain is relatively high, but the transverse strength, especially the tangential strength, is relatively low.

2、一次成型餐具的數(shù)量：

2. Quantity of tableware to be molded at one time:

一次性餐具設(shè)備一個標(biāo)準(zhǔn)周期成型的餐具數(shù)量主要影響以下兩個方面：

The quantity of tableware in a standard cycle of disposable tableware equipment mainly affects the following two aspects:

（1）影響單機的生產(chǎn)率：

(1) Impact on single machine productivity:

成型機一個標(biāo)準(zhǔn)周期成型的餐具數(shù)量過少，會造成生產(chǎn)率低，反之?dāng)?shù)量過多，機構(gòu)的體積増大、慣性増大，定位精度降低，運動速度也隨之降低，使生產(chǎn)率降低，故應(yīng)考慮一個標(biāo)準(zhǔn)周期成型的餐具數(shù)量應(yīng)適中。

If the quantity of tableware formed in a standard cycle of the molding machine is too small, the productivity will be low. On the contrary, if the quantity is too large, the volume and inertia of the mechanism will increase, the positioning accuracy will be reduced, and the movement speed will also be reduced, which will reduce the productivity. Therefore, it should be considered that the number of tableware formed in a standard cycle should be moderate.

（2）單機設(shè)備造價的影響：

(2) Impact of single equipment cost:

由于壓制每個餐具所需的壓制力是一定的，一次成型的餐具數(shù)量越多，受力越大成型機就越龐大，造價當(dāng)然也就越高。

Because the pressing force required for pressing each tableware is certain, the more tableware to be molded at one time, the greater the force, the larger the molding machine, and of course, the higher the cost.

順便指出，這里所說的壓制力是指該一次性餐具設(shè)備的較大工作能力，在實際使用中，用戶可根據(jù)實際情況進行調(diào)整。

By the way, the pressing force mentioned here refers to the larger working capacity of the disposable tableware equipment. In actual use, users can adjust according to the actual situation.
