Description

Technical Field

[0001] This utility model relates to the technical field of hot pressing equipment for various fabric sizes, and in particular to a hot pressing equipment applicable to various fabric sizes. Background Technology

[0002] In recent years, with the advancement of textile technology, the demand for seamless stitching and heat transfer printing has gradually emerged. Among these technologies, shaping and transferring fabrics through hot pressing is a common method. Current hot pressing equipment generally includes an upper hot pressing plate and a lower hot pressing plate. During operation, the fabric to be hot-pressed is placed on the lower hot pressing plate of the hot pressing device. The upper hot pressing plate presses down on the fabric on the lower hot pressing plate to perform heat pressing. Afterward, the upper hot pressing plate rises, and the hot-pressed product can be removed.

[0003] An existing hot pressing device applicable to various fabric sizes is not convenient for operators to provide stable positioning and fixation for the hot pressing products placed on the device when performing hot pressing operations on products of different purity and thickness. This causes the device to deviate during the hot pressing operation, affecting the quality of processing. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a hot pressing device applicable to various fabric sizes.

[0005] This utility model is achieved by the following technical solution: a hot pressing device applicable to various fabric sizes, including a support plate fixedly connected to the bottom of the workbench, a motor fixedly connected to the front of the workbench, a transmission assembly connected to the surface of the motor by a belt, a lead screw fixedly connected inside the transmission assembly, and a fixed support rotatably connected to the rear end of the lead screw.

[0006] An auxiliary rod is fixedly connected inside the workbench. A ball bearing bracket is threadedly connected to the surface of the lead screw. A bearing bracket is fixedly connected to the surface of the ball bearing bracket. A motor is fixedly connected to the front of the bearing bracket. A transmission assembly is belt-connected to the surface of the motor. A lead screw is fixedly connected inside the transmission assembly. A ball bearing bracket is threadedly connected to the surface of the lead screw. A motor is fixedly connected to the top of the ball bearing bracket. A transmission assembly is belt-connected to the output end of the motor. A hot-pressing support plate is fixedly connected inside the transmission assembly. Fixed support plates are fixedly connected to both the front and rear ends of the workbench. A rotating shaft is fixedly connected to the surface of the fixed support plate. A rotating support is hinged to the surface of the rotating shaft. An adjusting screw is threadedly connected inside the rotating support. A compaction plate is fixedly connected to the bottom of the adjusting screw. An adjusting handle is fixedly connected to the surface of the rotating support.

[0007] Through the above technical solution, the ball bearing bracket and the lead screw form a rolling friction pair, which significantly reduces motion resistance and eliminates gaps, ensuring high-precision repeatable positioning of lateral displacement, avoiding pattern offset or pressing deviation caused by cumulative errors. The symmetrical layout of the two auxiliary rods constitutes a parallel guide rail system, providing dual support for the load-bearing bracket, effectively dispersing the force under heavy load conditions, extending the life of the guide rail and improving motion stability.

[0008] As a further improvement to the above solution, the number of auxiliary rods is set to two, and the two auxiliary rods are symmetrically distributed on the left and right sides with the worktable as the center. The surfaces of the auxiliary rods are slidably connected to the bearing brackets.

[0009] Through the above technical solution, the motor drives the transmission component to rotate the lead screw, and the rotational motion is converted into linear motion through the ball bearing bracket, so that the support bracket can move laterally along the auxiliary rod. This breaks through the limitations of the traditional fixed work position, can cover a larger working area, and meet the processing needs of ultra-wide fabrics.

[0010] As a further improvement to the above solution, the lead screw is located at the bottom of the worktable, the fixed support is fixedly connected to the inner wall of the worktable, and the transmission assembly is rotatably connected to the front of the worktable.

[0011] Through the above technical solution, the second motor drives the second lead screw to realize the vertical lifting of the support bracket. Combined with the lateral movement function, it forms a two-dimensional planar adjustment system that can adapt to composite fabrics with different heights. The second ball bearing bracket and the support bracket adopt a sliding fit to form a secondary motion unit independent of the main motion, so that the hot pressing plate can adjust its height independently while maintaining a horizontal position, thereby realizing layered and progressive pressure.

[0012] As a further improvement to the above solution, the second ball bearing bracket is slidably connected to the surface of the support bracket, the hot-pressing support plate is located at the top of the worktable, and the second ball bearing bracket is located at the top of the worktable.

[0013] As a further improvement to the above solution, the second transmission component is rotatably connected to the right end of the support bracket, and the third transmission component is rotatably connected to the top of the ball bearing bracket.

[0014] As a further improvement to the above solution, the number of fixed support plates is set to several, and the fixed support plates are symmetrically distributed back and forth around the worktable, with the rotation axis located at the top of the worktable.

[0015] Through the above technical solution, the three motors directly drive the hot pressing plate to reciprocate. Compared with pneumatic / hydraulic methods, it has the characteristics of fast response speed and strong pressure controllability. The holding time and pressure curve can be programmed. The hot pressing plate integrates heating elements and, combined with the active pressure mechanism, can establish a stable temperature zone at the moment of contact, avoiding fabric damage caused by local overheating. It is especially suitable for heat-sensitive synthetic fibers.

[0016] As a further improvement to the above solution, the bottom of the compaction plate contacts the top surface of the workbench, and the adjusting screw extends through the rotating support to the top of the compaction plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention, by setting a rotating support on the surface of the fixed support plate and the rotating shaft for rotational adjustment, can limit and fix the front and rear positions of products placed on the worktable for hot pressing, in conjunction with the rotating adjustment screw driving the bottom compaction plate. This ensures the stability of the hot pressing support plate on the worktable during product processing and prevents the product from shifting during hot pressing, thus affecting the processing quality.

[0019] This invention, through the design of a rotating support hinged to a rotating shaft, allows the compaction plate to have a certain degree of angular freedom. Combined with the spiral lifting of the adjusting screw, it can automatically compensate for unevenness on the fabric surface, ensuring uniform pressure across the entire width. The fine-tooth thread pair formed by the adjusting screw and the adjusting handle precisely controls the contact pressure between composite materials, preventing fiber breakage caused by residual air bubbles or excessive compression. The design of the adjusting screw passing through the rotating support forms a rigid constraint, and combined with the self-locking characteristics of the thread pair, it can maintain the set pressure value in a vibration environment, ensuring the stability of continuous production.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example:

[0029] Please combine Figure 1-5 This embodiment of a hot pressing device applicable to various fabric sizes includes a support plate 2 fixedly connected to the bottom of a workbench 1, a motor 3 fixedly connected to the front of the workbench 1, a transmission assembly 4 connected to the surface of the motor 3 by a belt, a lead screw 5 fixedly connected inside the transmission assembly 4, and a fixed support 6 rotatably connected to the rear end of the lead screw 5.

[0030] An auxiliary rod 8 is fixedly connected inside the workbench 1. A ball bearing bracket 9 is threadedly connected to the surface of the lead screw 5. A bearing bracket 10 is fixedly connected to the surface of the ball bearing bracket 9. A motor 11 is fixedly connected to the front of the bearing bracket 10. A transmission assembly 12 is belt-connected to the surface of the motor 11. A lead screw 13 is fixedly connected inside the transmission assembly 12. A ball bearing bracket 14 is threadedly connected to the surface of the lead screw 13. A motor 15 is fixedly connected to the top of the ball bearing bracket 14. A transmission assembly 16 is belt-connected to the output end of the motor 15. A hot press plate 17 is fixedly connected inside the transmission assembly 16. Fixed support plates 18 are fixedly connected to both the front and rear ends of the workbench 1. A rotating shaft 19 is fixedly connected to the surface of the fixed support plate 18. A rotating support 20 is hinged to the surface of the rotating shaft 19. An adjusting screw 21 is threadedly connected inside the rotating support 20. A compaction plate 22 is fixedly connected to the bottom of the adjusting screw 21. An adjusting handle 23 is fixedly connected to the surface of the rotating support 20.

[0031] The ball bearing bracket 9 and the lead screw 5 form a rolling friction pair, which significantly reduces motion resistance and eliminates gaps, ensuring high-precision repeatable positioning of lateral displacement and avoiding pattern offset or pressing deviation caused by accumulated errors. The symmetrical layout of the two auxiliary rods 8 forms a parallel guide rail system, providing double support for the load-bearing bracket 10, effectively dispersing the force under heavy load conditions, extending the life of the guide rail and improving motion stability.

[0032] The number of auxiliary rods 8 is set to two, and the two auxiliary rods 8 are symmetrically distributed on the left and right sides with the worktable 1 as the center. The surface of the auxiliary rods 8 is slidably connected to the bearing bracket 10.

[0033] The motor-3 drives the transmission assembly-4 to rotate the lead screw-5. The rotational motion is converted into linear motion through the ball bearing bracket-9, allowing the support bracket-10 to move laterally along the auxiliary rod-8. This breaks through the limitations of traditional fixed workstations, can cover a larger working area, and meet the processing needs of ultra-wide fabrics.

[0034] The lead screw 5 is located at the bottom of the worktable 1, the fixed support 6 is fixedly connected to the inner wall of the worktable 1, and the transmission assembly 4 is rotatably connected to the front of the worktable 1. By setting the rotating support 20 to rotate and adjust on the surface of the fixed support plate 18 and the rotating shaft 19, the product to be processed and hot-pressed on the worktable 1 can be limited and fixed in front and back position by rotating the adjusting screw 21 to drive the bottom pressing plate 22. This ensures the stability of the hot pressing support plate 17 on the worktable 1 during product processing and avoids the product from shifting during hot pressing on the worktable 1, which would affect the processing quality during hot pressing.

[0035] Motor 2 11 drives lead screw 2 13 to realize the vertical lifting of the support bracket 10. Combined with the lateral movement function, it forms a two-dimensional planar adjustment system that can adapt to composite fabrics with different heights. Ball bearing bracket 2 14 and support bracket 10 adopt a sliding fit to form a secondary motion unit independent of the main motion, so that the hot pressing plate 17 can adjust its height independently while maintaining a horizontal position, realizing layered and progressive pressure.

[0036] The second ball bearing bracket 14 is slidably connected to the surface of the support bracket 10, the hot press support plate 17 is located on the top of the worktable 1, and the second ball bearing bracket 14 is located on the top of the worktable 1.

[0037] Transmission component 2 12 is rotatably connected to the right end of the support bracket 10, and transmission component 3 16 is rotatably connected to the top of the ball bearing bracket 2 14.

[0038] The number of fixed support plates 18 is set to several, and the fixed support plates 18 are symmetrically distributed back and forth with the worktable 1 as the center, and the rotating shaft 19 is located at the top of the worktable 1.

[0039] The motor 15 directly drives the hot press plate 17 to reciprocate. Compared with pneumatic / hydraulic methods, it has the characteristics of fast response speed and strong pressure controllability. The holding time and pressure curve can be programmed. The hot press plate 17 integrates heating elements and, combined with the active pressure mechanism, can establish a stable temperature zone at the moment of contact, avoiding fabric damage caused by local overheating. It is especially suitable for heat-sensitive synthetic fibers.

[0040] The bottom of the compaction plate 22 contacts the top surface of the workbench 1. The adjusting screw 21 extends through the rotating support 20 to the top of the compaction plate 22. By setting the rotating support 20 to be hinged to the rotating shaft 19, the compaction plate 22 has a certain degree of angular freedom. With the spiral lifting of the adjusting screw 21, it can automatically compensate for the unevenness of the fabric surface and ensure uniform pressure across the entire width. The fine-tooth thread pair formed by the adjusting screw 21 and the adjusting handle 23 precisely controls the contact pressure between the composite materials, preventing fiber breakage caused by air bubbles or excessive compression. The design of the adjusting screw 21 passing through the rotating support 20 forms a rigid constraint. With the self-locking characteristics of the thread pair, the set pressure value can be maintained in a vibration environment, ensuring the stability of continuous production.

[0041] The implementation principle of a hot pressing device applicable to multiple fabric sizes in this embodiment is as follows: When the rotating support 20 is adjusted to rotate on the surfaces of the fixed support plate 18 and the rotating shaft 19, the product to be hot-pressed on the worktable 1 can be positioned and fixed in the front-to-back direction by rotating the adjusting screw 21 and driving the bottom pressing plate 22. This ensures the stability of the hot pressing support plate 17 on the worktable 1 during product processing, preventing the product from shifting during hot pressing and thus affecting the processing quality. The design of the rotating support 20 hinged to the rotating shaft 19 gives the compaction plate 22 a certain degree of angular freedom. Combined with the spiral lifting of the adjusting screw 21, it can automatically compensate for the unevenness of the fabric surface and ensure uniform pressure across the entire width. The fine-tooth thread pair formed by the adjusting screw 21 and the adjusting handle 23 precisely controls the contact pressure between the composite materials, preventing fiber breakage caused by residual air bubbles or excessive compression. The design of the adjusting screw 21 passing through the rotating support 20 forms a rigid constraint. Combined with the self-locking characteristics of the thread pair, it can maintain the set pressure value in a vibration environment, ensuring the stability of continuous production.
