全降解一次性餐具设备特点

Disposable tableware equipment is a production equipment of fully degradable tableware with simplified structure, high production efficiency and using corn, corncob, rice fiber and other environmental protection materials as raw materials.

该设备构造性能特点有：由于挤出机挤出端直接螺连片材成型器，省略了辊压成片机。格外是该C型片材成型器在设计上转变了传统机械设计中认为金属腔体内的阻挡体在受压条件下须平衡固定的思维，设计成一点与外体连接，通过适当增加连接处的厚度与宽度来保障机械强度，继而直接的实现了C型片材成型。另外，挤出机挤出端口与片材成型器密闭螺连，玉米、玉米芯被推入螺杆碾压推进之时产生了摩擦高温，在物料被C型或"-"型缝槽挤出一接触外界空气，即形成了爆米花效应而自然的膨化，省去了传统工艺中的发泡过程。

The structure and performance characteristics of the equipment are as follows: due to the direct screw connection of the sheet former at the extrusion end of the extruder, the roll forming machine is omitted. In particular, the design of the C-type sheet former has changed the thinking that the barrier in the metal cavity must be balanced and fixed under pressure in the traditional mechanical design, and is designed to be connected with the outer body at one point, so as to ensure the mechanical strength by appropriately increasing the thickness and width of the connection, and then directly realize the C-type sheet forming. In addition, the extrusion port of the extruder is tightly screwed with the sheet former, and the friction high temperature is generated when the corn and corn cob are pushed into the screw for rolling and pushing. When the material is extruded by the C-type or "-" type slot and contacts the external air, it forms the popcorn effect and natural expansion, eliminating the foaming process in the traditional process.

而且推进螺杆设计成双线渐深螺纹构成的双头挤出结构，增加了工效。生产过程为全物理变化，产品用后可全降解或作饲料，对环保具有积极的推动作用。

Moreover, the propulsion screw is designed into a double headed extrusion structure composed of double thread and gradually deep thread, which increases the work efficiency. The production process is full physical change. The product can be fully degraded or used as feed after use, which plays a positive role in promoting environmental protection.

该一次性餐具设备的工作原理：采用降解的植物原料，比如玉米、玉米芯、稻谷纤维等，从挤出机料斗经搅拌进入推进螺杄，物料在螺杄与螺套之间挤碾向前推进，当螺杄达到一定转速时，物料在碾挤摩擦过程之中温度上升，其由C型成片器的出口端挤出时，一接触外界空气，即会自然膨化，省略了传统工艺中的发泡工序。冷却水的通道是为规避物料温度太高而焦糊。

Working principle of the disposable tableware equipment: degraded plant raw materials, such as corn, corncob, rice fiber, etc., are mixed from the extruder hopper into the propulsion screw, and the materials are extruded and pushed forward between the screw and the screw sleeve. When the screw reaches a certain speed, the temperature of the materials rises during the process of grinding and extrusion friction, and it is extruded from the outlet end of the C-type flaker, Once exposed to external air, it will expand naturally, omitting the foaming process in the traditional process. The channel of cooling water is to avoid burning due to too high material temperature.

变频器1.3控制电机转速，以在较高挤出速度与合适温度中调到越佳转速。从挤出机岀来的膨化片材，切割成段后的片材经过雾化冷湿机再经过蒸汽加湿机的加湿摊平并且柔软化增加了韧性之后，传送到成型机进行成型。成型后的产品送到干燥涂胶台，对干燥后的产品表面涂刷可降解、耐高热温、没损害的胶水，经涂胶的产品再送远红外烘干机上快速烘干，末后经包装与消毒后便可出厂。

Frequency converter 1.3 controls the speed of the motor to adjust the speed at higher extrusion speed and suitable temperature. After the expanded sheet from the extruder is cut into sections, it is sent to the forming machine for forming after being humidified and flattened by the atomization cold humidifier, and then softened and softened by the steam humidifier to increase the toughness. The formed products are sent to the drying gluing table. The surface of the dried products is coated with degradable, high temperature resistant and undamaged glue. The glued products are sent to the far-infrared dryer for rapid drying. Finally, they can leave the factory after packaging and disinfection.
