Description

Technical Field

[0001] The utility model relates to the technical field of elongation equipment, in particular to elongation equipment for high-strength TPU composite materials. Background Art

[0002] Thermoplastic polyurethane elastomer is also called thermoplastic polyurethane rubber, abbreviated as TPU. Thermoplastic polyurethane rubber is crosslinked by intermolecular hydrogen bonds or slightly crosslinked between macromolecular chains. With the increase or decrease of temperature, these two crosslinked structures are reversible. The intermolecular force weakens in the molten state or solution state, and after cooling or solvent evaporation, strong intermolecular forces connect them together again, restoring the performance of the original solid. Typical TPU such as spandex, etc.

[0003] For example, the authorized announcement number "CN213972551U" is a stretching device for processing thermoplastic polyurethane elastomer. Although the anti-deviation device set can play a role in positioning and guiding, it can prevent the first magnetic attraction plate from shifting in position when closing with the second magnetic attraction plate, thus ensuring the clamping effect and further guaranteeing the smooth progress of the stretching operation. Through the closing mechanism set, pressing the lower handle to close the first magnetic attraction plate and the second magnetic attraction plate and cooperating with the buffering effect of the spring elasticity can reduce the risk of pinching hands when placing the elastomer. However, due to the certain viscosity of TPU, the stretched TPU is very easy to adhere to the stretching device, and the operator still needs to spend time removing the stretched TPU from the stretching device, which not only increases the workload of the operator, but also reduces the efficiency of TPU stretching treatment to a certain extent.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Refer to Figures 1-4, an elongation device for high-strength TPU composite materials, including an elongation device body 1. A plurality of support legs 2 are provided on the lower surface of the elongation device body 1, and the support legs 2 play a role in supporting the elongation device body 1. On both sides of the upper surface of the elongation device body 1, first mounting blocks 3 are provided. Between the two first mounting blocks 3, a first positioning rod 4 and a second positioning rod 5 are provided. Two thread segments with opposite helix directions are provided on the second positioning rod 5, which facilitates the two sliders 7 to move closer to or away from each other. A motor 6 is provided on one side surface of the elongation device body 1. One end of the second positioning rod 5 is rotatably connected to the first mounting block 3, and the other end of the second positioning rod 5 is fixedly connected to the output end of the motor 6. Two sliders 7 are slidably connected above the elongation device body 1. The two sliders 7 correspond to the two thread segments on the second positioning rod 5 one by one. The lower ends of the sliders 7 are threadedly connected to the thread segments on the second positioning rod 5. The two sliders 7 are both slidably connected to the first positioning rod 4. On the upper surfaces of the two sliders 7, second mounting blocks 8 are provided on the sides away from each other. On the upper surfaces of the two sliders 7, two third mounting blocks 9 are provided. Between the two third mounting blocks 9 on the same slider 7, a disassembly roller 10 is rotatably connected. On the sides of the two third mounting blocks 9 on the same side away from the disassembly roller 10, first handles 11 are provided. On the rear surfaces of the first handles 11, first rotating shafts 12 are provided. One end of the first rotating shaft 12 is fixedly connected to the disassembly roller 10. On the sides of the two second mounting blocks 8 facing away from each other, second handles 13 are provided. On one side of each second handle 13, a second rotating shaft 14 is provided. The two second rotating shafts 14 are both threadedly connected to the corresponding second mounting blocks 8. The ends of the two second rotating shafts 14 away from the second handles 13 are rotatably connected to a pressing block 15. The pressing block 15 is matched with the disassembly roller 10, and the cross-section of the pressing block 15 is arc-shaped. On the sides of the two second mounting blocks 8 facing away from each other, two first end blocks 16 are provided. On the side surfaces of the plurality of first end blocks 16, first sliding rods 17 are provided. One end of the first sliding rod 17 slidably penetrates through the second mounting block 8 and is connected to the pressing block 15. An operation screen 18 is provided on the front surface of the elongation device body 1, and the operation screen 18 is electrically connected to the motor 6.

[0020] A first spring 19 is sleeved outside each of the plurality of first sliding rods 17, and the plurality of first springs 19 are all arranged between the second mounting block 8 and the first end block 16. The first spring 19 plays a role in resetting. When the pressing block 15 clamps the disassembly roller 10, the first spring 19 is in a compressed state. When the second handle 13 is rotated, it is convenient for the pressing block 15 to disengage from the disassembly roller 10.

[0021] On the upper surfaces of the two sliders 7, scraping blades 20 are provided. The scraping blades 20 are arranged directly below the disassembly roller 10. By providing the scraping blades 20, the sticky substances on the disassembly roller 10 can be scraped off.

[0022] On the lower surface of the two scraping blades 20, there are two second sliding rods 21. The lower ends of the second sliding rods 21 penetrate through the sliding blocks 7 in a sliding manner and are provided with second end blocks 22. A second spring 23 is sleeved outside the second sliding rods 21. The upper end of the second spring 23 is connected to the lower surface of the sliding block 7, and the lower end of the second spring 23 is connected to the upper surface of the second end block 22. The second spring 23 is in a stretched state. Under the action of the tensile force of the second spring 23, the upper end of the scraping blade 20 abuts against the dismounting roller 10, facilitating scraping the viscous substances on the dismounting roller 10 clean.

[0023] On the surfaces of the two sliding blocks 7, there are two strip-shaped through holes 24. At the lower ends of the two pressing blocks 15, there are two limiting rods 25. A plurality of limiting rods 25 all penetrate through the corresponding strip-shaped through holes 24 and are provided with third end blocks 26. The limiting rods 25 are provided to make the pressing blocks 15 run more smoothly.

[0024] On one side of the two third mounting blocks 9 away from the dismounting roller 10, there are two third handles 27. On the rear surfaces of the two third handles 27, there are third rotating shafts 28. The two third rotating shafts 28 are both threadedly connected to the corresponding third mounting blocks 9. On the surfaces of the two dismounting rollers 10 close to the third handles 27, there are abutting grooves 29. The rear ends of the third rotating shafts 28 abut against the inner wall of the rear of the abutting grooves 29. By screwing the third handles 27, the third rotating shafts 28 abut tightly against the inner wall of the rear of the abutting grooves 29, preventing the dismounting roller 10 from rotating.

[0025] Working principle: First, place the two ends of the TPU on the two dismounting rollers 10 respectively, and then rotate the second handle 13. Since the second rotating shaft 14 is threadedly connected to the second mounting block 8 and the second rotating shaft 14 is rotatably connected to the pressing block 15, under the limiting action of the first sliding rod 17, the pressing block 15 clamps the TPU with the dismounting roller 10; after the installation is completed, operate the operation screen 18 to start the motor 6, so that the second positioning rod 5 rotates. Since the sliding block 7 is threadedly connected to the threaded section on the second positioning rod 5 and the first positioning rod 4 limits the two sliding blocks 7, the two sliding blocks 7 move away from each other to stretch the TPU; after the stretching is completed, first rotate the second handle 13. Since the second rotating shaft 14 is threadedly connected to the second mounting block 8 and the second rotating shaft 14 is rotatably connected to the pressing block 15, under the limiting action of the first sliding rod 17, the pressing block 15 is separated from the dismounting roller 10. By rotating the first handle 11, the dismounting roller 10 rotates towards the TPU direction. The operator does not need to spend time removing the stretched TPU from this stretching device, reducing the workload of the operator and also improving the efficiency of the stretching process of the TPU to a certain extent.

[0026] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
