植物纤维餐具的生产与玉米淀粉餐具一样吗?

The exhaust path of the upper mold is: directly from the slit of the upper mold or from the slit to the guide ring groove of the upper mold pit to the transverse exhaust hole of the heating body to the longitudinal exhaust hole of the heating body;

下模排气路径∶下模体狭缝到排气小孔到排出，或堵块狭缝到电热盘孔空挡到下模托中孔空档到排下。此时模腔中的物料经模塑、脱水已固化成型。

Exhaust path of the lower die: from the slit of the lower die body to the exhaust hole to discharge, or from the slit of the blocking block to the central hole of the electric heating plate to the middle hole of the lower die holder to discharge. At this time, the material in the mold cavity has been solidified and formed after molding and dehydration.

然后上模执行松模、开模动作∶即转模气缸在外接气缸的作用下上移，便完成了松模开模动作;

Then the upper die performs the action of loosening and opening the die: that is, the mold turning cylinder moves up under the action of the external cylinder to complete the action of loosening and opening the die;

下模的脱模是由顶吹或抽吹装置来完成的∶即顶杆在薄型气缸的带动下上顶或下抽，顶杆端部和导套之间结合的锥面就形成缝隙，压缩空气此时从进气孔经顶杆中孔到缝隙吹向制品底部，消除了制品和模具间的负压，使制品和模具的粘结被剥离。而且由于一次性餐具设备高速气的喷出还清除了模腔中的原料的残渣，保证了排气通道的一直畅通。

The demoulding of the lower mold is completed by the top blowing or pumping device: that is, the ejector rod is driven up or down by the thin cylinder, and the conical surface combined between the end of the ejector rod and the guide sleeve forms a gap. At this time, the compressed air is blown to the bottom of the product from the air inlet hole through the middle hole of the ejector rod to the gap, eliminating the negative pressure between the product and the mold, so that the bonding between the product and the mold is stripped. Moreover, due to the high-speed gas ejection of disposable tableware equipment, the residue of raw materials in the mold cavity is also removed to ensure that the exhaust channel is unblocked all the time.

通常来说顶吹式脱模装置适于径深比大于的制品，如盘类∶而抽吹式用于径深比小于的制品，如杯类。此外，顶吹或抽吹的脱模结构除用锥面相结合外，还可有多种结构，只要杆在上顶（或下抽）状态，复位状态下，顶杆端部和导套的结合面既能开启又能闭合即是本设备的关键所在，顶吹和抽吹之间的转换可更换顶杆、导套及弹簧等零件即可。

Generally speaking, the top blowing demoulding device is suitable for products with a diameter depth ratio greater than, such as discs, while the suction blowing device is suitable for products with a diameter depth ratio less than, such as cups. In addition, the demoulding structure of top blowing or pumping can also have a variety of structures in addition to the combination of conical surfaces. As long as the rod is in the upper top (or lower pumping) state and in the reset state, the joint surface between the end of the top rod and the guide sleeve can be opened and closed, which is the key of the equipment. The conversion between top blowing and pumping can replace the top rod, guide sleeve, spring and other parts.

同理，模腔内排气通道设置也可有多种形式，在上模加热体中设置一个或多个和导流环槽相通的排气孔，或在加热体的外周分布若干个排气孔，或在上模凹坑的周边分布若干个排气孔，以及由上述设置的各种不同组合，这里就不一一叙述。

Similarly, the exhaust channel in the mold cavity can also be set in various forms. One or more exhaust holes connected with the guide ring groove are set in the upper mold heating body, or several exhaust holes are distributed around the heating body, or several exhaust holes are distributed around the pit of the upper mold, as well as various combinations set by the above, which will not be described one by one here.

该一次性餐具设备符合了植物纤维餐具的成型工艺要求，从一个新的角度解决了排气等压、均流的思路，使制品的质量得到一个飞跃，特别是顶吹（抽吹）的原理和设计，从源头上解决了模具堵塞，气流不通的难题。构思新颖，结构轻巧，制作简单，作用良好，解决了长期以来存在的脱模难题。该设备使得碗、盘、杯等各种形状、各种规格的一次性餐饮具制品的成型和脱模得以顺利圆满的实现。

The disposable tableware equipment meets the requirements of the forming process of plant fiber tableware, solves the idea of equal pressure and flow sharing of exhaust from a new angle, and makes a leap in the quality of products, especially the principle and design of top blowing (pumping blowing), which solves the problem of mold blockage and blocked air flow from the source. The utility model has the advantages of novel conception, light structure, simple manufacture and good function, and solves the problem of demoulding for a long time. The equipment enables the molding and demoulding of disposable tableware products of various shapes and specifications such as bowls, plates and cups to be successfully realized.
