Description

Technical Field

[0001] This utility model relates to the technical field of TPU production feeding devices, and in particular to a TPU production feeding device. Background Technology

[0002] Thermoplastic polyurethane elastomer (TPU), as a high-performance polymer material, has demonstrated an irreplaceable role in many fields in recent years. TPU combines the high elasticity of rubber with the plasticity of plastics, and possesses a series of excellent properties such as high strength, high toughness, wear resistance, oil resistance, and hydrolysis resistance.

[0003] Existing TPU production is usually a continuous industrial production process, which requires the feeding device to supply materials stably and uninterruptedly. Any interruption or instability in feeding may lead to fluctuations in the production process, or even cause product quality problems and increase production costs. Therefore, a TPU production feeding device is proposed.

[0004] A feeding device for TPU production, disclosed in publication number CN222495018U, includes a base. A support is fixedly connected to the top of the outer surface of the base. A first motor assembly is fixedly connected to one side of the outer surface of the support. A screw feeding device is installed at the output end of the first motor assembly. A feed hopper is fixedly connected to the top of the outer surface of the screw feeding device. A feed pipe is fixedly connected to one side of the outer surface of the screw feeding device. A cleaning structure is provided on the top of the outer surface of the feed hopper, and a dredging structure is provided on one side of the outer surface of the feed pipe. This invention, through the cleaning structure and the use of brushes, can clean the inner wall of the feed hopper, thereby preventing the residue of rubber products from remaining on the inner wall of the feed hopper, which would reduce raw material utilization and increase processing costs. It also prevents residual raw materials from clogging the bottom of the feed hopper, thus avoiding serious impact on the feeding process.

[0005] While the aforementioned patent achieves its goal of cleaning the inner wall of the feed hopper through a cleaning structure with brushes, thus preventing the residue of rubber products that could reduce raw material utilization and increase processing costs, and also preventing residual material from clogging the bottom of the feed hopper and severely affecting the feeding process, this device does not easily perform pre-mixing of the materials. Pre-mixing can effectively prevent material stratification and agglomeration, ensuring material uniformity and providing a guarantee for the production of high-quality TPU products.
