Description

Technical Field

[0001] This utility model relates to the field of mica tape preparation technology, specifically a hot-pressing composite device for a three-layer high-performance mica tape. Background Technology

[0002] Three-layer high-performance mica tape typically consists of a core layer, a reinforcing layer, and an adhesive layer. The core layer uses natural mica sheets or synthetic mica paper. The reinforcing layer significantly improves mechanical strength and impact resistance by stacking multiple layers of mica sheets or composite reinforcing fibers, ensuring that it is not easily damaged under complex stress environments. The adhesive layer uses a high-temperature adhesive to bond the core layer and the reinforcing layer, while ensuring that the structure remains stable under high-temperature environments.

[0003] At present, a hot press laminating machine can be used to produce three-layer high-performance mica tape. During the production process, as the radius of the material on the winding roller and the unwinding roller changes, the winding speed of the material will have a speed difference with the unwinding speed. This speed difference will cause uneven force on the material during winding, which will pull on the material during transportation, causing interlayer peeling or delamination, resulting in a reduction in the performance of the final product. Utility Model Content

[0004] The purpose of this invention is to provide a hot-pressing composite device for a three-layer high-performance mica tape to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hot-pressing composite device for a three-layer high-performance mica strip includes:

[0007] Rotary winding rollers mounted on the first machine base, and three sets of unwinding rollers mounted on the second machine base;

[0008] The three sets of unwinding rollers are connected by a linkage structure, which can drive the three sets of unwinding rollers to rotate synchronously.

[0009] One set of the unwinding rollers is connected to the winding roller via a synchronization mechanism. The synchronization mechanism includes an adaptation component and a speed-changing component. The speed-changing component connects the winding roller and the unwinding roller. The adaptation component includes a retraction member disposed on a first machine base. The retraction member cooperates with an adjustment component disposed on the first machine base. When the radius of the winding roller changes, it can drive the retraction member to move up and down relative to the first machine base, thereby triggering the adjustment component to drive the speed-changing component to operate, so that the ratio of the rotational linear velocity of the winding roller to the rotational linear velocity of the unwinding roller remains constant.

[0010] The hot-pressing composite device for the three-layer high-performance mica tape described above: the adapting component includes a mounting platform on a first machine base, on which two sets of plug-in cylinders are symmetrically arranged. Each set of plug-in cylinders is provided with a first spring. One end of the first spring abuts against the bottom of the plug-in cylinder, and the other end abuts against a retracting member slidably disposed in the plug-in cylinder.

[0011] The hot-pressing composite device for the three-layer high-performance mica tape described above: the relief component includes a plug rod slidably disposed in the plug cylinder, a rotating roller is rotatably installed between two sets of the plug rods, and a rack plate is provided on one set of the plug rods.

[0012] The hot-pressing composite device for the three-layer high-performance mica tape described above: the adjusting component includes a bidirectional lead screw rotatably mounted on the first machine base, a gear coaxially arranged on the bidirectional lead screw, the gear meshing with the rack plate, and two sets of threaded sleeves symmetrically arranged on the bidirectional lead screw and threadedly connected thereto.

[0013] The hot-pressing composite device for the three-layer high-performance mica tape described above: the speed-changing component includes a first cone and a second cone, each of the first and second cones being provided in two sets, the two sets of the first cones being slidably connected to the winding roller and rotatably connected to the two sets of threaded sleeves respectively, the two sets of the second cones being coaxially fixed to the unwinding roller, and the first cone and the second cone being connected by a linkage belt.

[0014] The hot-pressing composite device for the three-layer high-performance mica belt described above: the linkage structure includes a synchronous pulley coaxially arranged on the unwinding roller, and adjacent sets of synchronous pulleys are connected by a toothed belt.

[0015] The hot-pressing composite device for the three-layer high-performance mica tape described above: The second machine base is also provided with a platform, and the platform is provided with three sets of pressing structures. The pressing structure includes sleeves symmetrically arranged on the platform. A telescopic rod is slidably arranged inside the sleeve. An abutting roller is rotatably installed between two sets of telescopic rods. A second spring is sleeved on each set of telescopic rods. One end of the second spring abuts against the abutting roller, and the other end abuts against the sleeve.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By setting up a synchronization mechanism and utilizing the cooperation between the adaptation component and the speed change component, the transmission ratio between the winding roller and the unwinding roller can be adjusted in real time according to the changes in the radius of the mica tape on the winding roller and the radius of the roll material on the unwinding roller. This ensures that the winding linear speed of the winding roller and the unwinding linear speed of the unwinding roller are consistent, thereby avoiding the pulling of the mica tape during the manufacturing process due to the different material transmission speeds, reducing damage to the material roll material, and thus improving the quality of the final product.

[0018] Meanwhile, by setting up a pressure-reducing structure, the tension of the roll material during transmission can be adjusted to keep the tension of the material relatively constant during transmission. In conjunction with the synchronization mechanism, this can further reduce the pulling during material transportation, thereby improving product quality. Attached Figure Description

The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0030] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0031] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0032] Please see Figures 1-9 In this embodiment of the invention, a hot-pressing composite device for a three-layer high-performance mica strip includes:

[0033] A winding roller 3 is rotatably mounted on the first machine base 1, and three sets of unwinding rollers 4 are rotatably mounted on the second machine base 2; the three sets of unwinding rollers 4 are connected by a linkage structure, which can drive the three sets of unwinding rollers 4 to rotate synchronously.

[0034] Specifically, please refer to Figure 9 The linkage structure includes a synchronous pulley 17 coaxially mounted on the unwinding roller 4. Two adjacent sets of synchronous pulleys 17 are connected by a toothed belt 19. With the cooperation of the toothed belt 19 and the synchronous pulleys 17, the three sets of unwinding rollers 4 can rotate synchronously and stably.

[0035] Preferably, please refer to Figure 1 , Figure 2 , Figure 8The aforementioned winding roller 3 is coaxially fixed with the output shaft of the motor fixedly installed on the first machine base 1; the three sets of unwinding rollers 4 are used to install the core layer, adhesive layer and reinforcing layer from top to bottom. The three sets of roll material have the same radius and pass through the hot press roller group 5 set on the second machine base 2 in sequence, and then pass through the cooling roller 101 set on the first machine base 1 and connect to the winding roller 3. The initial radius of the winding roller 3 is equal to the initial radius of the roll material on the unwinding roller 4.

[0036] When the motor is started, the motor drives the winding roller 3 to rotate continuously in the same direction, which can wind the roll material on the unwinding roller 4 onto the winding roller 3. During the production process, the hot pressing roller 5 can melt the adhesive on the adhesive layer, thereby bonding the core layer and the reinforcing layer, bonding the three-layer structure into one layer. Then, under the cooling of the cooling roller 101, the three-layer roll material is stably bonded and wound onto the winding roller 3.

[0037] One set of the unwinding rollers 4 is connected to the winding roller 3 via a synchronization mechanism. The synchronization mechanism includes an adaptation component and a speed change component. The speed change component connects the winding roller 3 and the unwinding roller 4. The adaptation component includes a retraction member disposed on the first machine base 1. The retraction member cooperates with an adjustment component disposed on the first machine base 1. When the radius of the winding roller 3 changes, it can drive the retraction member to move up and down relative to the first machine base 1, thereby triggering the adjustment component to drive the speed change component to operate, so that the ratio of the rotational linear velocity of the winding roller 3 to the rotational linear velocity of the unwinding roller 4 remains constant.

[0038] The adaptation component includes a mounting platform 6 disposed on a first machine base 1. Two sets of plug-in cylinders 9 are symmetrically disposed on the mounting platform 6. Each set of plug-in cylinders 9 is provided with a first spring 14. One end of the first spring 14 abuts against the bottom of the plug-in cylinder 9, and the other end abuts against a retracting member slidably disposed in the plug-in cylinder 9.

[0039] The retraction component includes a plug rod 10 slidably disposed within the plug tube 9, a rotating roller 24 rotatably mounted between two sets of plug rods 10, and a rack plate 11 disposed on one set of plug rods 10;

[0040] For details, please refer to Figure 3 , Figure 4 , Figure 7The first spring 14 is always in a compressed state, pushing the rotating roller 24 to fit against the winding roller 3. As the winding roller 3 winds the mica tape, causing the overall radius to increase, the radius of the roll material on the three sets of unwinding rollers 4 gradually decreases. The mica tape on the winding roller 3 will press the rotating roller 24 in the opposite direction, so that the rotating roller 24 rises relative to the first machine platform 1. During the rising of the rotating roller 24, the adjustment component is triggered, which can adjust the rotation speed between the unwinding roller 4 and the winding roller 3, so that the winding speed of the winding roller 3 is consistent with the unwinding speed of the unwinding roller 4, reducing the pulling on the material, avoiding material damage, and thus helping to improve product quality.

[0041] Specifically, please refer to Figures 3-7 The adjustment assembly includes a bidirectional lead screw 13 rotatably mounted on the first machine base 1. A gear 16 is coaxially arranged on the bidirectional lead screw 13. The gear 16 meshes with the rack plate 11. Two sets of threaded sleeves 18 are also symmetrically arranged on the bidirectional lead screw 13 and threadedly connected to it.

[0042] The speed change assembly includes a first cone 12 and a second cone 15. Both the first cone 12 and the second cone 15 are provided in two sets. The two sets of the first cone 12 are slidably connected to the winding roller 3 and rotatably connected to the two sets of threaded sleeves 18 respectively. The two sets of the second cone 15 are coaxially fixed to the unwinding roller 4, and the first cone 12 and the second cone 15 are connected by a linkage belt 7.

[0043] In detail, the aforementioned winding roller 3 and unwinding roller 4 are as follows: Figure 6 As shown in the connection, in the initial state, the two sets of first cones 12 are far apart from each other. At this time, the transmission ratio between the winding roller 3 and the unwinding roller 4 is one to one. With the winding action of the winding roller 3, the overall radius of the winding roller 3 increases, forcing the rotating roller 24 to drive the insertion rod 10 and the rack plate 11 to rise. During this process, the rack plate 11 and the gear 16 enter the meshing transmission state, driving the bidirectional screw 13 to rotate, so that the two sets of threaded sleeves 18 drive the two sets of first cones 12 to move closer to each other, squeezing the linkage belt 7, thereby increasing the transmission ratio between the winding roller 3 and the unwinding roller 4, increasing the unwinding speed of the unwinding roller 4, and adapting to the winding speed of the winding roller 3.

[0044] Further, please refer to Figure 1 , Figure 2 , Figure 8The second machine platform 2 is also provided with a platform 8, which is provided with three sets of pressing structures. The pressing structure includes a sleeve 20 symmetrically arranged on the platform 8. A telescopic rod 21 is slidably arranged inside the sleeve 20. A pressing roller 23 is rotatably installed between two sets of telescopic rods 21. A second spring 22 is sleeved on each set of telescopic rods 21. One end of the second spring 22 abuts against the pressing roller 23, and the other end abuts against the sleeve 20.

[0045] In detail, the second spring 22 is always in a compressed state, pushing the abutment roller 23 to move towards the outside of the sleeve cylinder 20. During the hot pressing of the three-layer roll material, the roll material on the three sets of unwinding rollers 4 passes through the three sets of abutment rollers 23 respectively. At this time, the abutment rollers 23 can squeeze the roll material under the action of the second spring 22, thereby controlling the tension of the roll material in real time. This further adjusts the winding speed of the winding roller 3 and the unwinding speed of the unwinding roller 4, so that the winding speed of the winding roller 3 and the unwinding speed of the unwinding roller 4 are consistent, reducing the traction on the roll material caused by the difference in speed, thereby improving the quality of product production.
