[0002] TPU is a thermoplastic polyurethane elastomer rubber, which is mainly divided into polyester type and polyether type. It has a wide hardness range, is wear-resistant, oil-resistant, transparent, and has good elasticity. It is widely used in daily necessities, sporting goods, toys, decorative materials and other fields. Halogen-free flame-retardant TPU can also replace soft PVC to meet the environmental protection requirements of more and more fields. The so-called elastomer refers to a polymer material with a glass transition temperature lower than room temperature, an elongation at break>50%, and good recovery after the external force is removed. Polyurethane elastomer is a relatively special category of elastomers. The hardness range of polyurethane elastomer is very wide, and the performance range is very wide. Therefore, polyurethane elastomer is a type of polymer material between rubber and plastic. It can be heated and plasticized, and there is no or little cross-linking in the chemical structure.

At this time, the separation barrel (11) can generate vibration, which can shake off the raw materials blocked in the filter screen (13). After the contact block (16) contacts the wall of the separation barrel (11), it will first retract into the inner cavity of the movable groove (17) and then bounce outward through the spring (21), so that the contact block (16) can always hit the separation barrel (11). At the same time, the first elastic blocking belt (18) will move with the movement of the contact block (16) to block the movable groove (17); S4: While the separation barrel (11) is performing separation work, it rotates on the outer wall of the scraper rod (27). The scraper rod (27) can also process the inner cavity of the separation barrel (11) and can scrape off the raw materials adhering to the inside of the separation barrel (11). When it is necessary to discharge the solid raw materials, the sealing cover (4) is removed and the servo motor (24) is started to drive the screw rod (26) to rotate in the inner cavity of the movable groove (25), so that the movable block (30) can be threadedly connected with the screw rod (26). At this time, the receiving assembly (29) can move the solid raw materials to the top, so that the solid raw materials can be discharged.
