Description

Technical Field

[0001] This invention relates to the field of membrane processing technology, and in particular to a high-permeability waterproof TPU membrane and raw material processing equipment. Background Technology

[0002] In modern industry and daily life, TPU (thermoplastic polyurethane) film is widely used in clothing, footwear, medical, packaging and other fields due to its excellent elasticity, abrasion resistance, low temperature resistance and environmental friendliness.

[0003] Traditional TPU membranes often employ a single-layer structure design, where breathability and waterproofing performance are often mutually restrictive: increasing the membrane porosity to improve breathability leads to a significant decrease in waterproofing performance, making it difficult to prevent liquid penetration; conversely, reducing pore size or using a dense structure to ensure waterproofing results in a substantial reduction in breathability, failing to meet the needs of certain applications.

[0004] Meanwhile, in the raw material processing stage, the production of high-permeability waterproof TPU membranes requires extremely high standards for the uniformity of raw material mixing, particle size consistency, and degree of dryness. Existing raw material processing equipment mostly uses a single stirring method, which makes it difficult to achieve rapid and uniform mixing of multiple raw materials, easily leading to fluctuations in membrane performance. Furthermore, if the raw material uniformity and dryness are insufficient, it will affect the structural uniformity of the membrane after molding, resulting in unstable breathability and waterproof performance, and even the formation of bubbles or defects in the membrane, seriously affecting the transparency and mechanical properties of the membrane.

[0005] Based on the above reasons, this invention proposes a high-permeability waterproof TPU film and raw material processing equipment, which can effectively improve the air permeability and waterproof performance of TPU film, and can also achieve efficient mixing and drying of raw materials for TPU film production, thereby effectively improving the production stability of TPU film.

A connecting vertical plate is symmetrically fixedly connected to the ring plates. A horizontal plate is fixedly connected to the top surface of the vertical plate through the top plate and the ring plate. An electric push rod is fixedly connected to the horizontal plate. One end of the electric push rod is fixedly connected to the top surface of the processing tank.

[0016] Preferably, the rotation drive assembly includes a mounting plate, which is fixedly connected to the bottom surface of the processing tank. A motor is fixedly connected to the bottom surface of the mounting plate, and a rotating shaft is fixedly connected to the output end of the motor.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] This invention utilizes the synergistic effect of waterproof and breathable polyurethane, polyether polyurethane, polycaprolactam, and modifiers in the breathable and waterproof layer to give the TPU film excellent waterproof performance, effectively blocking moisture penetration. Furthermore, the combined effect of polymethyl methacrylate and ethylene-vinyl alcohol copolymer in the toughness layer effectively enhances the film's toughness and puncture resistance. Additionally, the composite structure of polytetrafluoroethylene and nano-silica in the wear-resistant layer effectively improves the wear resistance of the TPU film, thus giving the TPU film good mechanical properties.

[0024] This invention uses an airflow drying device to blow hot air into the inner cavity of a movable tube. The hot air heats the inner cavity of the movable tube and the heat-conducting plate. As the hot air flows continuously, the air pressure at the through hole decreases, and the raw material particles in the processing tank continuously enter the inner cavity of the movable tube through the through hole. The hot air is used to dry the raw material particles, and the raw material is then transported to the processing equipment. This improves the dryness of the raw material and reduces the impact of moisture in the raw material on the production quality of high-permeability waterproof TPU film.

[0025] This invention uses a motor to drive a circular plate to rotate, which in turn drives a stirring shaft to rotate around a movable tube. The movement of the stirring shaft causes a third gear to mesh with a third ring gear, which in turn drives the stirring shaft to rotate. The rotation of the stirring shaft then drives the stirring rod on it to rotate. By rotating the stirring shaft and stirring rod at different positions, efficient mixing of the raw materials in the processing tank can be achieved, improving the mixing effect of various raw materials and effectively improving the production and processing quality of high-permeability waterproof TPU film.

[0061] This invention utilizes the synergistic effect of waterproof and breathable polyurethane, polyether polyurethane, polycaprolactam, and modifiers in the breathable and waterproof layer, as well as the composite structure of polytetrafluoroethylene and nano-silica in the wear-resistant layer, to give this TPU film excellent waterproof performance, effectively blocking the penetration of moisture. Furthermore, the combined effect of polymethyl methacrylate and ethylene-vinyl alcohol copolymer in the toughness layer effectively enhances the toughness and puncture resistance of the film, giving this TPU film good mechanical properties.

[0062] like Figure 2-8 As shown, an embodiment of the present invention provides a raw material processing device for high-permeability waterproof TPU film, which is used to process high-permeability waterproof TPU film. It includes a processing tank 1, a plurality of feed pipes 2 are fixedly connected to the outer wall of the processing tank 1 near the top surface, and a movable pipe 3 is movably connected to the center of the side wall of the processing tank 1. An airflow drying device 4 is installed at the bottom end of the movable pipe 3, and a plurality of heat-conducting plates 27 are evenly distributed and fixedly connected to the inner cavity of the movable pipe 3. The heat-conducting plates 27 are inclined.

[0063] In the technical solution of this embodiment, during the production of high-permeability waterproof TPU film, the movable tube 3 is connected to the production equipment via a pipeline, and then the airflow drying equipment 4 is started. The airflow drying equipment 4 blows hot air into the inner cavity of the movable tube 3. The hot air heats the inner cavity of the movable tube 3 and the heat-conducting plate 27. Due to the continuous blowing of the hot air, the air pressure at the through hole 5 decreases, and the raw material particles in the processing tank 1 continuously enter the inner cavity of the movable tube 3 through the through hole 5. The hot air dries the raw material particles and transports the raw material to the processing equipment, thereby improving the dryness of the raw material and reducing the impact of moisture in the raw material on the production quality of the high-permeability waterproof TPU film.

[0064] Furthermore, several support rods 30 are evenly distributed and fixedly connected on the bottom surface of the treatment tank 1. The support rods 30 are inclined to the side away from the movable tube 3, which can improve the stability of the treatment tank 1.

[0065] Furthermore, the movable tube 3 is symmetrically provided with several through holes 5 on the side wall of the inner cavity of the processing tank 1. The movable tube 3 is provided with a particle control component 6, which includes a ring plate 11. Several ring plates 11 are evenly distributed on the side wall of the inner cavity of the processing tank 1. A connecting vertical plate 12 is symmetrically fixedly connected to the ring plates 11. The top surface of the vertical plate 12 penetrates the top plate 9 and the circular plate 7 and is fixedly connected to a horizontal plate 13. An electric push rod 14 is fixedly connected to the horizontal plate 13. One end of the electric push rod 14 is fixedly connected to the top surface of the processing tank 1.

[0066] In the technical solution of this embodiment, according to the actual production needs of high-permeability waterproof TPU film, the electric push rod 14 is operated and controlled. The electric push rod 14 drives the horizontal plate 13 to move, the horizontal plate 13 drives the vertical plate 12 to move, and the vertical plate 12 drives the circular plate 11 to move on the outer wall of the movable tube 3. When the circular plate 11 completely closes the through hole 5, it is convenient to stir the raw material and avoid the leakage of the raw material. By controlling the staggered position of the circular plate 11 and the through hole 5, the particle size and uniformity of the raw material input into the processing equipment can be controlled, thereby effectively improving the processing quality of high-permeability waterproof TPU film.

[0067] A circular plate 7 is movably connected to the bottom surface of the inner cavity of the processing tank 1. The circular plate 7 is movably connected to the movable tube 3. A rotation drive assembly 8 is provided on the lower side of the circular plate 7. The rotation drive assembly 8 includes a mounting plate 15. The mounting plate 15 is fixedly connected to the bottom surface of the processing tank 1. A motor 16 is fixedly connected to the bottom surface of the mounting plate 15. A rotating shaft 17 is fixedly connected to the output end of the motor 16. A first gear 18 is fixedly connected to the rotating shaft 17. Two first ring gears 19 are fixedly connected to the outer wall of the movable tube 3. The first gear 18 meshes with the lower first ring gear 19. A second gear 20 meshes with the upper first ring gear 19. A circular shaft 21 is movably connected to the center of the side wall of the second gear 20. The circular shaft 21 is fixedly connected to the processing tank 1. A second ring gear 22 meshes with the other side of the second gear 20. The second ring gear 22 is fixedly connected to the bottom surface of the circular plate 7.

[0068] In the technical solution of this embodiment, after all the raw materials for the production of high-permeability waterproof TPU film are added to the processing tank 1 in proportion, the motor 16 is started. The motor 16 drives the rotating shaft 17 to rotate, and the rotating shaft 17 drives the first gear 18 to mesh with the lower first ring gear 19 to rotate. The first ring gear 19 drives the movable tube 3 to rotate. The rotation of the movable tube 3 can change the position of the through hole 5, which can not only achieve efficient feeding of raw material particles, but also push out the raw materials that are too large and cause blockage of the through hole 5 using the vertical plate 12, which is convenient for the production of high-permeability waterproof TPU film. In addition, the movable tube 3 drives the upper first ring gear 19 to rotate, the upper first ring gear 19 meshes with the second gear 20 to rotate, the second gear 20 meshes with the second ring gear 22 to rotate, and the second ring gear 22 drives the circular plate 7 to rotate. The rotation of the circular plate 7 can drive the raw material particles gathered on it, so that the raw material particles move continuously to the side of the movable tube 3, which is convenient for the feeding of raw materials.

[0069] A top plate 9 is movably connected to the inner cavity of the processing tank 1 near the top surface. A stirring and mixing assembly 10 is provided on the top plate 9. The stirring and mixing assembly 10 includes stirring shafts 23. Several stirring shafts 23 are provided, and each stirring shaft 23 is movably connected to the circular plate 7 and the top plate 9. The distance between the several stirring shafts 23 and the movable tube 3 is set in a gradient. Several stirring rods 24 are evenly distributed and fixedly connected to the side wall of the stirring shaft 23. A third gear 25 is fixedly connected to the top of each stirring shaft 23. Several third gears 25 mesh with the same third ring gear 26. The third ring gear 26 is fixedly connected to the inner wall of the processing tank 1.

[0070] In the technical solution of this embodiment, when the circular plate 7 rotates, the circular plate 7 drives the stirring shaft 23 to rotate around the movable tube 3. The movement of the stirring shaft 23 can cause the third gear 25 to mesh and rotate with the third ring gear 26. The third gear 25 drives the stirring shaft 23 to rotate, and the rotation of the stirring shaft 23 drives the stirring rod 24 on it to rotate. By rotating the stirring shaft 23 and the stirring rod 24 at different positions, the raw materials in the inner cavity of the processing tank 1 can be efficiently mixed, improving the mixing effect of various raw materials and further improving the production and processing quality of the high-permeability waterproof TPU film.

[0071] Furthermore, the diameter of the circular plate 7 is the same as the inner diameter of the processing tank 1, and the top surface of the circular plate 7 is inclined towards the side of the movable tube 3, which can realize the continuous accumulation of raw materials towards the side of the movable tube 3, which facilitates the mixing and discharge of raw materials.

[0072] Furthermore, annular grooves 28 are provided on both the inner and outer walls of the circular plate 7, and annular grooves 28 are provided on the outer wall of the top plate 9. Annular plates 29 are movably connected in the annular grooves 28. The annular plates 29 are fixedly connected to the inner wall of the processing tank 1 and the outer wall of the movable tube 3, respectively, so that the circular plate 7 and the top plate 9 can rotate stably in the inner cavity of the processing tank 1.
