Description

TECHNICAL FIELD

[0001] The utility model relates to thermoplastic polyurethane film production technical field, concretely to a kind of thermoplastic polyurethane film production feeding device. BACKGROUND

[0002] The prior art CN211030859U discloses a thermoplastic polyurethane elastomer film production feeding device, which proposes that the raw material particles need to be heat treated during the production of thermoplastic polyurethane elastomer film, and the raw material particles need to be uniformly placed by cooperating with the feeding device. However, the existing feeding device cannot filter the large volume raw material particles during use, which leads to uneven or difficult heat melting, and brings adverse effects. In addition, the installation and disassembly are inconvenient. The solution is to set a filter structure. When the particles are poured from the upper end of the device housing, the oversized particles will be filtered by the filter screen to prevent falling into the device housing. At the same time, the inner inclined surface prevents the particles from accumulating on the edge of the outer frame. By pulling the outer frame forward and pulling it out, the surface of the filter screen can be cleaned to ensure that the screen holes are not blocked, thereby ensuring the subsequent filtering effect.

[0003] The above-mentioned scheme and prior art do not control the feeding of raw material particles for thermoplastic polyurethane elastomer film production when feeding. If too many raw material particles enter the feeding device, the raw material particles inside the device will accumulate and affect the feeding efficiency, which cannot meet the actual use requirements.
