Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermoplastic polyurethane elastomer technology, and in particular to a continuous production apparatus for thermoplastic polyurethane elastomers. Background Technology
[0002] Thermoplastic polyurethane elastomer (TPU) is a type of elastomer that can be plasticized by heating and dissolved by solvents. It has excellent comprehensive properties such as high strength, high toughness, wear resistance, and oil resistance. It has good processing performance and is widely used in defense, medical, food and other industries.
[0003] A search revealed that patent CN209138583U discloses a continuous production apparatus for thermoplastic polyurethane elastomers. This apparatus can evenly spread the material on the loading plate, reducing manual intervention. However, it has the following drawbacks in its use:
[0004] 1. During the process of removing and replacing the loading plate, the equipment is in a shutdown state and cannot carry out continuous production operations, which reduces production efficiency.
[0005] Therefore, we propose a continuous production apparatus for thermoplastic polyurethane elastomers. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies where the device is in a standstill during the removal and replacement of the loading plate, resulting in reduced production efficiency. Therefore, this invention proposes a continuous production device for thermoplastic polyurethane elastomers.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A continuous production apparatus for thermoplastic polyurethane elastomers, comprising:
[0009] A support base is provided, with a controller fixed on one outer wall, a vessel body fixed on the surface of the support base, and a shell fixed on the inner side of the support base. The bottom outlet of the vessel body is connected to the shell through a pipe.
[0010] The bottom inner wall of the housing is fixed with two parallel guide rails, and a U-shaped slide block is slidably connected between the two guide rails. A partition is fixed on the bottom inner wall of the slide block, and multiple sliding grooves are opened on the bottom inner wall of the slide block. A loading plate is slidably connected between two adjacent sliding grooves, and the two loading plates are located on both sides of the partition.
[0011] An adjustment mechanism is provided on one side of the slide block for adjusting its position.
[0012] A leveling mechanism, which is disposed between the slide and the partition, is used to level materials;
[0013] A positioning mechanism is provided on one side of the loading plate and is used to position the loading plate.
[0014] In one possible design, the adjustment mechanism includes two connecting plates, which are respectively fixed at both ends of the guide rail. A first screw passes through the two connecting plates and is threaded through the slide block. A first motor is fixed on one side of one of the connecting plates, and the output shaft of the first motor is fixed to the first screw.
[0015] In one possible design, the leveling mechanism includes a second motor, a guide rod, and a second screw. The second motor is fixed to one side of the outer wall of the slide, the guide rod is fixed between the slide and the partition, and the second screw rotates through one side of the slide. The output shaft of the second motor is fixed to the second screw, and a material feeding rack is slidably connected to the outer wall of the guide rod. The second screw thread passes through the material feeding rack.
[0016] In one possible design, the positioning mechanism includes a groove and a positioning slot. The groove is formed on the bottom inner wall of the slide, and a positioning plate is slidably connected in the groove. The top of the positioning plate is provided with an inclined surface. Two springs are fixed between the positioning plate and the groove. The positioning slot is formed on the bottom of the loading plate, and the positioning slot and the positioning plate cooperate with each other.
[0017] In one possible design, side grooves are provided on both sides of the positioning plate, and multiple limiting blocks are fixed on the bottom inner wall of the slide block, with the limiting blocks cooperating with the side grooves.
[0018] In one possible design, the top of the positioning plate is provided with a spherical groove, and a ball bearing is provided inside the spherical groove.
[0019] In this application, during use, the processed material inside the reactor enters the shell through a pipe and then falls onto the loading plate. At this time, the second motor is started to drive the second screw to rotate, which in turn drives the unloading rack to slide along the guide rod, using the unloading rack to flatten the material. After a period of time, the first motor is started to drive the first screw to rotate, which in turn drives the slide to slide along the guide rail, causing the loading plate carrying the material to extend out of the shell, allowing the unused loading plate to enter the shell, thereby achieving the purpose of quickly replacing the loading plate. Then, the positioning plate is pressed to disengage from the positioning groove, the loading plate is removed and unloaded, and then the loading plate is pushed in along the slide groove. Under the guidance of the inclined surface, the positioning plate is pressed into the groove by the loading plate. When the positioning plate and the positioning groove are aligned, the spring pushes the positioning plate into the positioning groove, completing the positioning of the loading plate.
[0020] Beneficial effects: In this utility model, the continuous production device for thermoplastic polyurethane elastomer, through the arrangement of multiple structures such as slide, first motor and partition, can quickly replace the loading plate, reduce the downtime of the device, and thus improve production efficiency.
[0021] In this utility model, the continuous production device for thermoplastic polyurethane elastomer, through the setting of multiple structures such as grooves, positioning plates and positioning slots, allows people to quickly and easily replace the loading plate, saving people's energy.
[0022] In this invention, the loading plate can be quickly replaced, reducing the downtime of the device and thus improving production efficiency. It also allows people to quickly replace the loading plate, saving them time and effort. Attached Figure Description

[0030] Support base 1, controller 2 is fixedly mounted on one outer wall of support base 1, and vessel body 3 is fixedly mounted on the surface of support base 1. The structure and principle of vessel body 3 are the same as those of patent with publication number CN209138583U, so the structure and principle will not be described in detail. Shell 4 is fixedly mounted on the inner side of support base 1. The bottom outlet of vessel body 3 is connected to shell 4 through a pipe for feeding materials into shell 4.
[0031] Two parallel guide rails 5 are fixedly installed on the bottom inner wall of the housing 4. A U-shaped slide block 9 is slidably connected between the two guide rails 5. A partition 10 is fixedly installed on the bottom inner wall of the slide block 9. Multiple sliding grooves 11 are opened on the bottom inner wall of the slide block 9. A loading plate 12 is slidably connected between two adjacent sliding grooves 11. The two loading plates 12 are located on both sides of the partition 10. The partition 10 divides the interior of the slide block 9 into two spaces, thereby facilitating the quick replacement of the loading plate 12.
[0032] An adjustment mechanism is located on one side of the slide 9 and is used to adjust the position of the slide 9. The adjustment mechanism includes two connecting plates 6, which are respectively fixed at both ends of the guide rail 5. A first screw 8 is rotatably passed between the two connecting plates 6 and threaded through the slide 9. A first motor 7 is fixed on one side of one of the connecting plates 6, and the output shaft of the first motor 7 is fixed to the first screw 8. When the first motor 7 rotates, it drives the slide 9 to slide on the guide rail 5 through the first screw 8, thereby adjusting the position of the slide 9 and thus replacing the loading plate 12.
[0033] A leveling mechanism is installed between the slide block 9 and the partition plate 10 to level materials. The leveling mechanism includes a second motor 13, a guide rod 14, and a second screw 15. The second motor 13 is fixed to one side of the outer wall of the slide block 9. The guide rod 14 is fixed between the slide block 9 and the partition plate 10. The second screw 15 rotatably passes through one side of the slide block 9. The output shaft of the second motor 13 is fixed to the second screw 15. A material feeding rack 16 is slidably connected to the outer wall of the guide rod 14, and the second screw 15 is threaded through the material feeding rack 16. When the second motor 13 rotates, the second screw 15 drives the material feeding rack 16 to slide on the guide rod 14, thereby leveling the materials.
[0034] A positioning mechanism is provided on one side of the loading plate 12 for positioning the loading plate 12. The positioning mechanism includes a groove 17 and a positioning slot 23. The groove 17 is formed on the bottom inner wall of the slide block 9. A positioning plate 18 is slidably connected in the groove 17. The top of the positioning plate 18 is provided with an inclined surface. Two springs 19 are fixed between the positioning plate 18 and the groove 17 to provide elastic force for the positioning plate 18 to return to its original position. The positioning slot 23 is formed on the bottom of the loading plate 12. The positioning slot 23 cooperates with the positioning plate 18 to position the loading plate 12.
[0035] This application can be used in the field of thermoplastic polyurethane elastomers, or in other fields applicable to this application.

[0037] In another aspect of this embodiment, side grooves 20 are provided on both sides of the positioning plate 18, and multiple limiting blocks 21 are fixedly provided on the bottom inner wall of the slide block 9. The limiting blocks 21 cooperate with the side grooves 20. Through the cooperation of the limiting blocks 21 and the side grooves 20, the movement range of the positioning plate 18 can be further limited, preventing the positioning plate 18 from dislodging from the groove 17 and improving the stability of the positioning mechanism.
[0038] In another aspect of this embodiment, the top of the positioning plate 18 is provided with a spherical groove, and a ball bearing 22 is provided in the spherical groove.
