Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric technology, and in particular to a nonwoven fabric hot pressing device. Background Technology

[0002] Nonwoven fabric is a type of non-woven material. It is made by directly using polymer chips, short fibers or filaments to form a web through airflow or machinery, and then going through processes such as hydroentangling, needle punching, and hot pressing, and finally finishing to form a non-woven fabric.

[0003] When hot-pressing nonwoven fabrics, a hot-pressing device is required. Current hot-pressing devices are general-purpose, meaning they are suitable for various types of fabrics. As a type of fabric, nonwoven fabrics also require this type of hot-pressing device. However, different types of fabrics require different pressures during hot pressing, and current hot-pressing devices cannot adjust the pressure. Therefore, a nonwoven fabric hot-pressing device is proposed to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a nonwoven fabric hot pressing device to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A nonwoven fabric hot pressing device includes a processing table, a support base fixedly installed on the top of the processing table, a pressure plate arranged above the support base, nonwoven fabric inserted between the support base and the pressure plate, an adjusting plate arranged above the pressure plate, and multiple springs in a compressed state arranged between the pressure plate and the adjusting plate, with the upper and lower ends of the springs respectively fixedly connected to the sides of the adjusting plate and the pressure plate that are close to each other. The adjusting plate has a through hole, a limit plate installed in the through hole, and the adjusting plate can slide up and down on the outer surface of the limit plate through the through hole. The limit plate has multiple limit grooves evenly distributed vertically, and limit rods inserted in the limit grooves. Two parallel L-shaped fixing plates are fixedly installed on the top of the adjusting plate, and the limit rods are slidably installed between the two L-shaped fixing plates. The upper and lower ends of the limit plate are respectively fixedly installed with blocks, and connecting plates are fixedly installed on the rear side of each block. Each set of vertically parallel connecting plates is fixedly connected by a support plate, and the bottom of the support plate is fixedly installed on the processing table.

[0007] Furthermore, a heating box is provided on one side of the processing table, and a reserved hole is provided inside the heating box for the non-woven fabric to pass through. Heating plates are provided on both the upper and lower sides of the non-woven fabric inside the heating box.

[0008] Furthermore, a spacer is fixedly installed on the side of the L-shaped fixing plate away from the limiting plate.

[0009] Furthermore, a T-shaped tie rod is fixedly installed on the top of the limiting rod.

[0010] Furthermore, the support plate is provided with a limiting sliding hole, and a limiting sliding rod is slidably installed in the limiting sliding hole. One end of the limiting sliding rod is fixedly installed on one side of the pressure plate, and the other end of the limiting sliding rod extends to the outside of the limiting sliding hole and is fixedly installed with a limiting stop.

[0011] Furthermore, support legs are fixedly installed around the bottom of the processing table.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention removes the limiting rod from the limiting groove, thereby freeing the limiting plate from constraint. The limiting plate can then slide up and down within the through hole, adjusting the distance d between the pressure plate and the adjusting plate. As the spring force F = k*x, the spring constant k remains constant, while the spring elongation x changes continuously with the distance d between the adjusting plate and the pressure plate, thus altering the spring force F. This allows for adjustment of the pressure plate pressure based on the characteristics of the non-woven fabric. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-5 A nonwoven fabric hot pressing device includes a processing table 1, a support base 2 fixedly installed on the top of the processing table 1, a pressure plate 3 arranged above the support base 2, a nonwoven fabric 4 inserted between the support base 2 and the pressure plate 3, an adjusting plate 5 arranged above the pressure plate 3, and a plurality of springs 6 in a compressed state arranged between the pressure plate 3 and the adjusting plate 5, with the upper and lower ends of the springs 6 respectively fixedly connected to the sides of the adjusting plate 5 and the pressure plate 3 that are close to each other. The adjusting plate 5 has a through hole, and a limit plate 7 is installed in the through hole, and the adjusting plate 5 can be limited through the through hole. The plate 7 slides up and down on its outer surface. The limiting plate 7 has multiple limiting grooves 8 evenly distributed in the upper and lower parts. A limiting rod 9 is inserted into the limiting groove 8. Two parallel L-shaped fixing plates 10 are fixedly installed on the top of the adjusting plate 5. The limiting rod 9 is slidably installed between the two L-shaped fixing plates 10. The upper and lower ends of the limiting plate 7 are respectively fixedly installed with a stop block 11. A connecting plate 12 is fixedly installed on the rear side of each stop block 11. Each set of parallel connecting plates 12 is fixedly connected by a support plate 13. The bottom of the support plate 13 is fixedly installed on the processing table 1.

[0022] In the above embodiment, by removing the limiting rod 9 from the limiting groove 8, the limiting plate 7 is freed from constraint, meaning the limiting plate 7 can slide up and down within the through hole, thereby adjusting the distance d between the pressure plate 3 and the adjusting plate 5. As can be seen from the spring force F = k*x of the spring 6, the spring constant k of the spring 6 remains constant, and the elongation x of the spring 6 changes continuously with the distance d between the adjusting plate 5 and the pressure plate 3, thus causing the spring force F of the spring 6 to change accordingly, thereby adjusting the pressure of the pressure plate 3 according to the characteristics of the nonwoven fabric 4.

[0023] Specifically, a heating box 14 is provided on one side of the processing table 1. The heating box 14 has a reserved hole 15 for the non-woven fabric 4 to pass through. Heating plates 16 are provided on both the upper and lower sides of the non-woven fabric inside the heating box 14.

[0024] In the above embodiment, when the nonwoven fabric 4 passes through the reserved hole 15, the heating plate 16 inside the heating box 14 works to preheat the nonwoven fabric 4, thereby facilitating the pressure plate 3 to perform hot pressing treatment on the nonwoven fabric 4.

[0025] Specifically, a partition block 17 is fixedly installed on the side of the L-shaped fixing plate 10 away from the limiting plate 7.

[0026] In the above embodiment, the spacer 17 is used to block and limit movement.

[0027] Specifically, a T-shaped tie rod 18 is fixedly installed on the top of the limiting rod 9.

[0028] In the above embodiment, the limiting rod 9 is slid between the two L-shaped fixing plates 10 by pulling the T-shaped pull rod 18.

[0029] Specifically, the support plate 13 is provided with a limiting sliding hole 19, and a limiting sliding rod 20 is slidably installed in the limiting sliding hole 19. One end of the limiting sliding rod 20 is fixedly installed on one side of the pressure plate 3, and the other end of the limiting sliding rod 20 extends to the outside of the limiting sliding hole 19 and is fixedly installed with a limiting stop 21.

[0030] In the above embodiment, the limiting slide bar 20 slides up and down along the trajectory of the limiting slide hole 19, thereby causing the pressure plate 3 to move up and down in the vertical direction.

[0031] Specifically, support legs 22 are fixedly installed around the bottom of the processing table 1.

[0032] In the above embodiment, the bottom of the processing table 1 is supported by four support legs 22 at the bottom of the processing table.

[0033] Working principle: The pressure of the pressure plate 3 is adjusted according to the characteristics of the nonwoven fabric 4. The method is to drive the limiting rod 9 to slide by the T-shaped pull rod 18, so that one side of the limiting rod 9 moves out of the limiting groove 8. Then, the limiting plate 7 slides up and down in the through hole to adjust the distance d between the pressure plate 3 and the adjusting plate 5. According to the elastic force F = k*x of the spring 6, the spring constant k of the spring 6 remains unchanged, and the elongation x of the spring 6 changes continuously with the distance d between the adjusting plate 5 and the pressure plate 3, so that the elastic force F of the spring 6 also changes accordingly. This realizes the adjustment of the pressure of the pressure plate 3 according to the characteristics of the nonwoven fabric 4. The nonwoven fabric 4 to be heat-pressed passes through the reserved hole 15 inside the heating box 14. During this process, the heating plate 16 inside the heating box 14 works to preheat the nonwoven fabric 4. After the nonwoven fabric 4 is preheated, it passes between the pressure plate 3 and the support seat 2, that is, the nonwoven fabric 4 is heat-pressed by the pressure of the pressure plate 3.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
