Description

Technical Field

[0001] The utility model relates to the technical field of waterproof cloth production, in particular to an improved device for heat-sealing processing of PE waterproof cloth. Background Art

[0002] The waterproof fabric heat sealing device is a device used to process waterproof fabrics. Its main function is to bond different parts of the waterproof fabric together through heat sealing technology to enhance its waterproof performance. This device usually includes a heating element, a pressure system and a control system.

[0003] During operation, the tarpaulin to be treated is first placed in the working area of ​​the device, and then the appropriate heating temperature and pressure are set through the control system. The heating element heats the surface of the tarpaulin to a certain temperature to soften it, and then the pressure system is used to press the surfaces of two or more tarpaulins together to achieve bonding. Usually, the heating time and pressure are adjusted according to the material and thickness of the tarpaulin to ensure that the bonding effect achieves the expected waterproof performance.

[0004] The waterproof fabric heat sealing device plays an important role in the manufacture of waterproof clothing, waterproof tents, rain gear and other products, which can improve the waterproof performance and durability of the products. With the advancement of technology, modern waterproof fabric heat sealing devices continue to improve their automation and processing efficiency, making the production process more efficient and precise.

[0005] A search of publication number CN217922544U discloses a non-woven fabric thermal bonding device. The patent includes a first electric heating wire, a first heating roller, a telescopic rod, a spring, a second electric heating wire, and a second heating roller. The telescopic rod moves the bracket downward under the elastic action of the spring, changes the distance between the second heating roller and the first heating roller, and improves the application range of the device. At the same time, the spring enables the second heating roller to have a buffer force during thermal bonding to avoid damage to the fabric due to excessive pressure, thereby improving practicality. The first electric heating wire and the second electric heating wire are spirally arranged inside the first heating roller and the second heating roller. After power is turned on, the two can be evenly preheated to improve the bonding efficiency of the entire device.

[0006] In the above-mentioned prior art solution, multiple heating rollers are provided, and the temperatures of the multiple heating rollers are set so that the closer to the center, the higher the temperature is. Then, the multiple heating rollers heat the cloth in sequence. The heating rollers far away can preheat the cloth to avoid the situation where the cloth is suddenly exposed to a higher temperature and is damaged during preheating. Therefore, when the cloth is replaced, the temperatures of the multiple heating rollers need to be readjusted. The process is too complicated, and the multiple heating rollers are provided, resulting in high costs.

[0007] Therefore, we propose an improved device for heat-sealing PE waterproof fabrics. Utility Model Content

[0008] In order to solve the technical problems existing in the above-mentioned prior art, the utility model provides an improved device for heat-sealing processing of PE waterproof cloth.

[0009] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an improved device for heat-sealing processing of PE waterproof cloth, comprising an outer frame, a conveyor belt is arranged inside the outer frame, a telescopic cylinder is fixedly installed on the inner top wall of the outer frame, a heat conducting plate is fixedly installed on the output end of the telescopic cylinder, the heat conducting plate is in an arc shape whose height increases as it is farther away from the telescopic cylinder, and a heating module is fixedly installed on the top wall of the heat conducting plate close to the telescopic cylinder.

[0010] As a preferred technical solution of the utility model, a movable block is fixedly installed on the end of the top wall of the heat conduction plate away from the telescopic cylinder, a positioning block is arranged inside the outer frame, connecting rods are rotatably installed on the ends of the movable block and the positioning block that are close to each other, and a connecting sleeve frame is sleeved on the outside of the ends of the two connecting rods that are close to each other.

[0011] As a preferred technical solution of the utility model, a positioning bearing is fixedly installed on the top wall of the positioning block, and a threaded rod threadedly connected to the top wall of the outer frame is fixedly installed on the inner side wall of the positioning bearing.

[0012] As a preferred technical solution of the utility model, a buffer spring is arranged inside the connecting sleeve frame, and two ends of the buffer spring are respectively fixedly connected to the ends approaching each other on the two connecting rods.

[0013] As a preferred technical solution of the utility model, a plurality of ventilation slots are equidistantly formed on one end of the top wall of the heat conducting plate away from the telescopic cylinder.

[0014] As a preferred technical solution of the utility model, a support plate is fixedly installed on the inner wall of the outer frame, and the top wall surface of the support plate is in contact with the inner top wall surface of the conveyor belt.

[0015] The utility model provides an improved device for heat-sealing PE waterproof cloth, which has the following beneficial effects:

[0016] 1. An improved device for heat-sealing PE waterproof cloth. When the outer waterproof cloth moves from left to right through the conveyor belt, the waterproof cloth preferentially contacts the end of the heat-conducting plate away from the telescopic cylinder. The temperature of the end of the heat-conducting plate away from the telescopic cylinder is lower, so the heat-conducting plate can preheat the waterproof cloth. As the conveyor belt moves, the temperature that the waterproof cloth is exposed to becomes higher and higher, thereby reducing the possibility of damage to the waterproof cloth due to sudden exposure to high temperature. The heat generated by the heating module is conducted through the heat-conducting plate, so that the excess heat generated by the heating module can be used to preheat the waterproof cloth, thereby reducing the cost of preheating.

[0017] 2. This improved device for heat-sealing PE waterproof cloth, by threading the threaded rod and the top wall of the outer frame together, enables the threaded rod to limit the position of the positioning block, and when the threaded rod is rotated, the height of the positioning block will change with the rotation of the threaded rod, so as to facilitate the adjustment of the tilting amplitude of the end of the heat conduction plate away from the telescopic cylinder.

[0018] 3. This improved device for heat-sealing PE waterproof cloth increases the contact area between the end of the heat-conducting plate away from the telescopic cylinder and the external air through the ventilation groove, increases the heat dissipation speed of the end of the heat-conducting plate away from the telescopic cylinder, and further avoids the situation where the overall temperature of the heat-conducting plate is the same as the temperature generated by the heating module.

[0029] Embodiment: An improved device for heat-sealing PE waterproof fabric, such as Figure 1-Figure 3As shown, it includes an outer frame 1, a conveyor belt 2 is arranged inside the outer frame 1, a telescopic cylinder 3 is fixedly installed on the inner top wall of the outer frame 1, a heat conducting plate 4 is fixedly installed on the output end of the telescopic cylinder 3, and the heat conducting plate 4 is in an arc shape with a height higher as the end away from the telescopic cylinder 3 is fixedly installed, and a heating module 13 is fixedly installed on the top wall of the heat conducting plate 4 close to the telescopic cylinder 3. The heat conducting plate 4 is heated by the heating module 13. Since the position of the heating module 13 is close to the telescopic cylinder 3, the heat of the end of the heat conducting plate 4 far away from the telescopic cylinder 3 is lower. When the external waterproof cloth moves from left to right through the conveyor belt 2, the waterproof cloth preferentially contacts with the end of the heat conducting plate 4 far away from the telescopic cylinder 3, and the end of the heat conducting plate 4 far away from the telescopic cylinder 3 is in contact with the heat conducting plate 4. The temperature at one end of the cylinder 3 is lower, so the heat conducting plate 4 can preheat the waterproof cloth. As the conveyor belt 2 moves, the temperature to which the waterproof cloth is exposed becomes higher and higher, thereby reducing the possibility of the waterproof cloth being damaged due to sudden exposure to high temperature. The heat conducting plate 4 is in an arc shape whose height increases the further away from the telescopic cylinder 3, so that the end of the heat conducting plate 4 away from the telescopic cylinder 3 will not directly contact the waterproof cloth. The heat dissipation treatment is performed on the end of the heat conducting plate 4 away from the telescopic cylinder 3 to avoid the situation where the entire heat conducting plate 4 is at the same temperature when the heating module 13 works for a long time. The heat generated by the heating module 13 is conducted by the heat conducting plate 4, so that the excess heat generated by the heating module 13 can be used to preheat the waterproof cloth, thereby reducing the preheating cost.

[0030] A movable block 6 is fixedly installed on one end of the top wall of the heat conducting plate 4 away from the telescopic cylinder 3, a positioning block 7 is arranged inside the outer frame 1, and connecting rods 5 are rotatably installed on the ends of the movable block 6 and the positioning block 7 that are close to each other, and a connecting sleeve frame 10 is sleeved on the outside of the ends of the two connecting rods 5 that are close to each other. When the position of the positioning block 7 is limited, the end of the heat conducting plate 4 away from the telescopic cylinder 3 can be pulled by the two connecting rods 5 and the connecting sleeve frame 10, so that the end of the heat conducting plate 4 away from the telescopic cylinder 3 is tilted, thereby avoiding the situation that the end of the heat conducting plate 4 away from the telescopic cylinder 3 is in a horizontal state due to long use.

[0031] A positioning bearing 9 is fixedly installed on the top wall of the positioning block 7, and a threaded rod 8 threadedly connected to the top wall of the outer frame 1 is fixedly installed on the inner wall of the positioning bearing 9. By threading the threaded rod 8 and the top wall of the outer frame 1 together, the threaded rod 8 can limit the position of the positioning block 7, and when the threaded rod 8 is rotated, the height of the positioning block 7 will change with the rotation of the threaded rod 8, so as to facilitate the adjustment of the tilting amplitude of the end of the heat conducting plate 4 away from the telescopic cylinder 3.

[0032] A buffer spring 11 is provided inside the connecting sleeve 10, and the two ends of the buffer spring 11 are fixedly connected to the ends of the two connecting rods 5 that are close to each other. The two connecting rods 5 are fixedly connected together by the buffer spring 11, so that there is a certain movable space between the two connecting rods 5, thereby ensuring that the end of the heat conducting plate 4 away from the telescopic cylinder 3 has a certain swing amplitude, which facilitates the waterproof cloth to enter between the heat conducting plate 4 and the conveyor belt 2.

[0033] A plurality of ventilation slots 14 are equidistantly formed on the top wall of the heat conducting plate 4 at one end away from the telescopic cylinder 3. The ventilation slots 14 increase the contact area between the end of the heat conducting plate 4 away from the telescopic cylinder 3 and the external air, thereby increasing the heat dissipation rate of the end of the heat conducting plate 4 away from the telescopic cylinder 3, and further preventing the overall temperature of the heat conducting plate 4 from being the same as the temperature generated by the heating module 13.

[0034] A support plate 12 is fixedly installed on the inner wall of the outer frame 1, and the top wall of the support plate 12 is in contact with the inner top wall of the conveyor belt 2. The inner top of the conveyor belt 2 is supported by the support plate 12, so that when the heat conducting plate 4 squeezes the waterproof cloth, the waterproof cloth is prevented from bending as the conveyor belt 2 bends.

[0035] The working principle of this utility model:

[0036] When in use, the heat conducting plate 4 is heated by the heating module 13. Since the heating module 13 is located close to the telescopic cylinder 3, the heat of the end of the heat conducting plate 4 that is farther away from the telescopic cylinder 3 is lower. When the external waterproof cloth moves from left to right through the conveyor belt 2, the waterproof cloth preferentially contacts the end of the heat conducting plate 4 that is farther away from the telescopic cylinder 3. The temperature of the end of the heat conducting plate 4 that is farther away from the telescopic cylinder 3 is lower, so the heat conducting plate 4 can preheat the waterproof cloth. As the conveyor belt 2 moves, the temperature that the waterproof cloth contacts becomes higher and higher, reducing the waterproof cloth from being suddenly heated. The heat conducting plate 4 is in an arc shape with a height increasing the further away from the telescopic cylinder 3, so that the end of the heat conducting plate 4 away from the telescopic cylinder 3 will not directly contact the waterproof cloth. The heat dissipation treatment is performed on the end of the heat conducting plate 4 away from the telescopic cylinder 3 to avoid the situation where the entire heat conducting plate 4 is at the same temperature when the heating module 13 works for a long time. The heat generated by the heating module 13 is conducted through the heat conducting plate 4, so that the excess heat generated by the heating module 13 can be used to preheat the waterproof cloth, thereby reducing the preheating cost.

[0037] When in use, the threaded rod 8 is threadably connected to the top wall of the outer frame 1 so that the threaded rod 8 can limit the position of the positioning block 7, and when the threaded rod 8 is rotated, the height of the positioning block 7 will change with the rotation of the threaded rod 8, thereby facilitating adjustment of the tilting amplitude of the end of the heat conducting plate 4 away from the telescopic cylinder 3.

[0038] When in use, the contact area between the end of the heat conducting plate 4 away from the telescopic cylinder 3 and the external air is increased through the ventilation groove 14, thereby increasing the heat dissipation rate of the end of the heat conducting plate 4 away from the telescopic cylinder 3, further avoiding the situation where the overall temperature of the heat conducting plate 4 is the same as the temperature generated by the heating module 13.

[0039] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
