Advantages and disadvantages of plastic processing machines

Simple Structure: Many plastic refining machines, especially open-type ones, have a relatively simple overall structure. For example, the open-type plastic refining machine produced by Wuxi Tengyu Environmental Protection Technology Co., Ltd. mainly consists of a base, a connecting seat, and a table top to form a table-type structure. It is also composed of common components such as a transmission system, rollers, roller bearings, a frame, safety devices, electric heating devices, and an electrical control cabinet. This relatively simple structure makes the manufacturing process relatively easy, allowing for better control of the production cycle and cost. It also facilitates troubleshooting and maintenance by companies when equipment malfunctions. For smaller plastic product companies, whose maintenance technicians may have limited professional skills, a simple structure makes it easier for them to perform daily maintenance and simple repairs, ensuring normal production.

Open mill of plastic machine

Before starting: Operators must wear leather wrist guards, masks, and other protective equipment. Check that all equipment components are functioning properly, such as checking for foreign objects between the large and small gears and rollers, and checking the responsiveness and reliability of the emergency brake. At the same time, inspect the rubber material to avoid hard metal objects entering the rubber mill, which could cause a sudden increase in lateral pressure and damage the equipment. In addition, preheat the rollers according to process requirements and control the temperature rise rate. This is especially important in winter when there is a large temperature difference between the inside and outside. It is recommended to preheat the machine without a load, controlling the temperature rise rate to 1-2℃/min.

Main uses of the kneader

Used for the mastication and mixing of natural rubber and other polymeric elastomers. A closed mill is a machine that uses a pair of rotors with specific shapes that rotate relative to each other to intermittently masticate and mix polymeric materials under adjustable temperature and pressure in a closed state. In the processing of natural rubber and other polymeric elastomers, the closed mill, through strong stirring and shearing action, ensures that the rubber material and compounding agents are fully mixed, improving the plasticity of the rubber material. For example, the main purpose of masticating rubber in a closed mill is to break the macromolecular chains under mechanical, thermal, and chemical actions, increasing plasticity to meet various process requirements in manufacturing, such as compounding agent mixing, calendering, pattern shape, molding, rubber flow, and adhesion. Widely used in the processing of rubber, plastic, and other materials, such as mixing, mastication, and extrusion. A closed-type rubber mill, or closed mill, is mainly used for the mastication and mixing of rubber, and is also used for mixing plastics, asphalt materials, felt materials, enamel materials, and various synthetic resin materials. The main functions of a closed mill include mixing, mastication, and extrusion processing. During the mixing process, the closed mill uses its internal stirrer and heating system to bond different types of rubber or plastic materials together, ensuring uniform material mixing. During the mastication process, the closed mill uses high-speed stirring and high-temperature heating to melt the raw materials and form a uniform mixture. During extrusion processing, the closed mill extrudes the plasticized material through the extrusion port to form the desired product. The application and role of closed mills in the rubber industry are specifically reflected in plasticization, mixing, calendering, cooling, and granulation, providing strong support for the preparation of high-performance rubber products. At the same time, closed mills also play an important role in the processing of plastics and other materials, ensuring uniform material mixing and complete plasticization through stirring, heating, and mechanical transmission, ultimately achieving product extrusion processing.

The rules before starting the calender must be followed one by one!

Correct operation of an open mill first requires adjusting the roll gap to maintain balance. If the roll gap adjustment is uneven at both ends, it will cause the rollers to be overloaded, easily damaging the equipment, which is strictly prohibited. After work, cut off the power and close the water and steam valves.
