Description

Technical Field

[0001] The utility model relates to the technical field of TPU production, in particular to a feeding device for TPU production. Background Technique

[0002] The production of thermoplastic polyurethane elastomer (TPU) is a process of converting specific raw materials into high-performance polymer materials through a series of processes. It mainly uses polyols and isocyanates as the main raw materials. Polyols determine the soft segment properties of TPU and affect the flexibility, low-temperature resistance, etc. of the material. Isocyanates react with polyols to form hard segments, endowing the material with strength and hardness. The entire production process requires strict control of parameters such as temperature, pressure, and reaction time to ensure the quality and performance stability of the product. At the same time, in order to meet different application requirements, various additives such as antioxidants, lubricants, and flame retardants can also be added during the production process to improve the performance of TPU.

The output end of the electric push rod 503 extends into the inner cavity of the feeding box 2, and a first connecting cable 504 is fixedly connected to this end. One end of the first connecting cable 504 far from the output end of the electric push rod 503 is fixedly connected to one side of the bottom of the material guiding hose 4. The inner side wall of the reset cavity 502 is fixedly connected with a reset spring 505. The other end of the reset spring 505 is fixedly connected with a reset sliding plate 506 that is slidably connected to the reset cavity 502. The center of one side wall of the reset sliding plate 506 far from the reset spring 505 is fixedly connected with a reset support rod 507. One end of the reset support rod 507 far from the reset sliding plate 506 extends into the inner cavity of the feeding box 2, and a second connecting cable 508 is fixedly connected to this end.

[0025] Workflow: First, power on all electrical appliances and connect external controllers to each electrical appliance. The processing box 1 can produce TPU. The feeding box 2 can provide an installation space for the whole and a storage space for raw materials. The guiding hopper 3 can introduce various raw materials into the feeding box 2 through the guiding hose 4. And the setting of the hopper cover can seal and protect the guiding hopper 3 when it is not guiding materials, thus preventing other sundries from entering the feeding box 2 through the guiding hopper 3 and the guiding hose 4 to ensure the purity of the raw materials. The dispersing component 5 can regularly change the guiding direction of the guiding hose 4, making its guiding range relatively wide, so that the raw materials can be dispersed more evenly, thus avoiding affecting the subsequent feeding process. When guiding materials, start the electric push rod 503 in the driving cavity 501, and make it pull the first connecting cable 504 through its own contraction stroke, so as to drive the opening direction of the bottom of the guiding hose 4 to change through the first connecting cable 504. While the guiding hose 4 is changing direction, it will pull the second connecting cable 508, making the second connecting cable 508 drive the reset support rod 507 and the reset slide plate 506 to slide in the reset cavity 502 and pull the reset spring 505. When the electric push rod 503 extends, the pulling force of the second connecting cable 508 disappears, and the reset spring 505 drives the reset slide plate 506 and the reset support rod 507 to reset through its own resilience, that is, at the same time, drive the opening direction of the bottom of the guiding hose 4 to change in the opposite direction through the second connecting cable 508, forming a cycle to make the guiding direction of the guiding hose 4 change regularly and reciprocally. The mixing component 6 can mix and stir various raw materials, so that the mixing of various raw materials is uniform enough before feeding, thus ensuring the production quality of the subsequent TPU. Start the driving motor 601, and the driving motor 601 will drive the mixing support rod 603 to rotate through the transmission shaft 602. The mixing support rod 603 will drive the mixing plate 605 to rotate through the connecting seat 604, so as to continuously mix and stir the raw materials. In addition, the structure of the mixing plate 605 is relatively flexible, so when it is damaged, it is convenient to replace the damaged part in time, so that it does not need to be replaced as a whole while ensuring its mixing effect, thus reducing its maintenance cost. The raw materials can be filtered by the set feeding mesh plate 7 and fall into the processing box 1 for feeding. When installing the mixing plate 605, first sleeve it on the mixing support rod 603 through the connecting seat 604, and make the hole positions of the connecting bolts 606 on the connecting seat 604 correspond to the connecting screw holes 607. Finally, screw into the connecting screw holes 607 in the connecting screw holes 607. The disassembly is the same.
