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.

模具的设计不但要考虑木身的功能，还要考虑美学原理和人机工程学的原理。经过观察各酒店、餐馆和小吃店，采用统计方法确定中盘的尺寸。

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.

压制力的确定：

Determination of pressing force:

压制力的大小一方面决定了餐具产品的密实度，另一方面也决定了一次性餐具设备成型机的大小，压制力越大，餐具也密实，强度越高，但压制力越大，一次成型的餐具越多，成型机体积就越大，机身越笨重。因此压制力的大小和一次成型的餐具的数量应选择大小适中。

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、压制应力的确定：

1. Determination of pressing stress:

压制应力的大小决定了餐具的密实度。在没有规范或其它参考时，可以参照文献[机械设计手册]中木材的抗压强度来考虑。参照木材的物理力学特性，用木材的抗压强度限度作为参照值。木材的强度限度变化范围比较大，是不同木材的强度不同，二是不同的受力方向强度也不同，顺纹抗压强度都比较高，而横向格外是弦向强度比较低。

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、一次成型餐具的数量：

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

一次性餐具设备一个标准周期成型的餐具数量主要影响以下两个方面：

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

（1）影响单机的生产率：

(1) Impact on single machine productivity:

成型机一个标准周期成型的餐具数量过少，会造成生产率低，反之数量过多，机构的体积増大、惯性増大，定位精度降低，运动速度也随之降低，使生产率降低，故应考虑一个标准周期成型的餐具数量应适中。

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）单机设备造价的影响：

(2) Impact of single equipment cost:

由于压制每个餐具所需的压制力是一定的，一次成型的餐具数量越多，受力越大成型机就越庞大，造价当然也就越高。

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.

顺便指出，这里所说的压制力是指该一次性餐具设备的较大工作能力，在实际使用中，用户可根据实际情况进行调整。

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.
