[0002] The open mill is the abbreviation of open plastic refining machine. In the plastic products industry, it is usually called a two-roller machine or a two-roller machine. The main working parts are two rollers rotating in opposite directions. As the rollers rotate, the material is drawn into the gap between the two rollers and is subjected to strong shearing to achieve the purpose of mixing. The open mill is a kind of plastic mixing equipment used earlier by plastic product manufacturers. On the calender production line, the open mill is before the calender and after the mixer. Its function is to mix and plasticize the uniformly mixed raw materials, and provide the calender with relatively uniform mixed and plasticized materials for the calender to calender and mold plastic products. It is widely used in plastic product enterprises. The disadvantage is that the workers consume a lot of physical energy when operating. In a high temperature environment, the mixed materials need to be mixed and turned manually, and the number of manual flipping of the mixed plastic sheets has a great influence on the quality of the raw material mixing.
[0003] During the long-term operation of the existing mixing mill, due to the influence of vibration, wear, pressure, temperature and repeated disassembly and assembly, the baffle plate is seriously worn and has poor sealing. The gap between the baffle plate and the roller gradually increases, causing the material to escape from the gap and then bring in impurities and black spots at both ends of the roller, seriously affecting the product quality and production efficiency. Therefore, an automatic material baffle device for the roller of the mixing mill is proposed to solve the above problems. Utility Model Content
