Description

Technical Field

[0001] This utility model relates to the field of coating and bonding technology, and in particular to a bonding mechanism for a high-efficiency coating machine. Background Technology

[0002] Coating technology is a process technology that uniformly applies one or more layers of a specific material coating to the surface of an object. Due to its own advantages, it is widely used in many fields, such as electronics, packaging, printing, automobile manufacturing and building materials. With the continuous growth of market demand and the increasing requirements for product quality, coating machines have emerged.

[0003] After the material is coated by the coating machine, in order to improve the coating quality and enhance the product performance, it is necessary to bond multiple materials together. When bonding materials, a bonding mechanism is needed to ensure that the coating and the substrate are tightly bonded, thereby improving the coating quality and the stability of the product.

[0004] Currently, the bonding mechanism of coating machines on the market mainly consists of an unwinding unit, a bonding unit, and a control system. Its working principle is that the control system controls the unwinding unit, so that the roll material to be bonded enters the bonding unit, and then the bonding unit performs the bonding work. When the roll material to be bonded is used up, the unwinding roller needs to be removed from the unwinding frame. However, since the unwinding roller is installed on the unwinding frame with multiple keycaps and nuts, it is relatively troublesome to disassemble and replace it, thereby reducing the bonding efficiency of subsequent roll materials and failing to meet the needs of users. Utility Model Content

A clamping assembly is provided inside the fixed frame.

[0010] As a further description of the above technical solution:

[0011] The pressing mechanism includes a U-shaped frame, which is fixedly connected to the top right side of the base. An electric push rod is fixedly connected to the top inner side of the U-shaped frame. A connecting frame is fixedly connected to the output end of the electric push rod.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 2 , Figure 5 and Figure 6 This utility model provides an embodiment of a bonding mechanism for a high-efficiency coating machine, comprising a base 1, a disassembly mechanism 2 on the bottom left side of the base 1 for convenient and quick disassembly and replacement of the roller body after the fabric is used up, a winding assembly on the top left side of the base 1, the winding assembly including a connecting plate 5 and a winding roller 7, two connecting plates 5 respectively fixedly connected to the front and rear ends of the top left side of the base 1, grooves 6 are provided on the upper and lower ends of adjacent sides of the two connecting plates 5, the interior of the multiple grooves 6 respectively contacting the front and rear ends of the corresponding winding roller 7, the opposite sides of the two connecting plates 5 respectively fixedly connected to one side of the corresponding U-shaped block 207, a tensioning mechanism 3 is provided in the middle of the top of the base 1 for always maintaining the tension of the fabric to be processed, and a pressing mechanism 4 is provided on the top right side of the base 1 for convenient bonding of two different fabrics together;

[0035] The disassembly mechanism 2 includes an opening slot 201. A support plate 202 is fixedly connected to the bottom inner side of the opening slot 201. A servo motor 203 is fixedly connected to the top of the support plate 202. A cylindrical gear 204 is fixedly connected to the output end of the servo motor 203. Limiting slots 205 are provided on both the left and right sides inside the opening slot 201. A rack 206 is slidably connected inside the limiting slot 205. The two racks 206 are respectively meshed with the left and right sides of the cylindrical gear 204. A U-shaped block 207 is fixedly connected to the opposite side of the two racks 206. The width of the two racks 206 matches the width of the corresponding limiting slot 205.

[0036] Specifically, the servo motor 203 drives the cylindrical gear 204 to rotate, and the rack 206, which meshes tightly with the cylindrical gear 204, moves within the corresponding limiting groove 205. The U-shaped block 207, which is directly connected to the rack 206, moves accordingly with the movement of the rack 206. This displacement is further transmitted to the connecting plates 5 on both sides, allowing the connecting plates 5 to move closer to the center. When the connecting plates 5 move to a certain extent towards the center, the structures at both ends of the take-up roller 7 will make tight contact with the corresponding grooves 6, thus completing the installation of the take-up roller 7. When the roll material on the take-up roller 7 is used up and a new roll material needs to be replaced, the take-up roller 7 can be easily disassembled by simply following the reverse steps. This disassembly and installation process is relatively simple, thereby improving the convenience of operation for workers.

[0037] Reference Figure 2 , Figure 3 and Figure 4 The tensioning mechanism 3 includes a fixed frame 301, which is fixedly connected to the top center of the base 1. The fixed frame 301 has sliding grooves 302 on both the front and rear sides. A double-acting screw 303 is rotatably connected inside the front sliding groove 302. Slider 304 is slidably connected to the upper and lower sides of the two sliding grooves 302. The front slider 304 is threaded to the upper and lower sides of the outer wall of the double-acting screw 303. A rotating rod 305 is rotatably connected to the front side of the fixed frame 301. The rear end of the rotating rod 305 passes through the corresponding sliding groove 302 and is fixedly connected to the driving bevel gear 306. A driven bevel gear 307 is fixedly connected to the middle of the outer side of the double-acting screw 303. The driven bevel gear 307 meshes with the driving bevel gear 306. A pressing assembly is provided inside the fixed frame 301. The pressing assembly includes a U-shaped plate 308. The front and rear sides of the two U-shaped plates 308 are fixedly connected to the corresponding sliders 304. A rotating roller 309 is rotatably connected inside the U-shaped plate 308.

[0038] Specifically, since the two take-up rollers 7 rotate in opposite directions, when it is necessary to adjust the tension of the roll material, the driving bevel gear 306 on the outer side of the rotating rod 305 rotates accordingly. The driving bevel gear 306 and the driven bevel gear 307 are meshed, so the driven bevel gear 307 will also rotate with the rotation of the driving bevel gear 306. At this time, the bidirectional screw 303 also starts to rotate, and the U-shaped plate 308 on its outer side will move towards the center when the bidirectional screw 303 rotates. The rotating rollers 309 inside the U-shaped plate 308 will also move with the movement of the U-shaped plate 308. These rotating rollers 309 can align and squeeze the roll material on the corresponding take-up roller 7. In this way, the roll material can maintain a taut state during the conveying process, thereby ensuring the bonding effect of the subsequent roll material.

[0039] Reference Figure 1 and Figure 2 The pressing mechanism 4 includes a U-shaped frame 401, which is fixedly connected to the top right side of the base 1. An electric push rod 402 is fixedly connected to the top inner side of the U-shaped frame 401. A connecting frame 403 is fixedly connected to the output end of the electric push rod 402. A first pressing roller 404 is rotatably connected inside the connecting frame 403. A second pressing roller 405 is rotatably connected to the inner side of the U-shaped frame 401.

[0040] Specifically, the electric push rod 402 can drive the first pressing roller 404 to move downward, and cooperate with the second pressing roller 405 to tightly bond the two different roll materials together, thereby completing the bonding work of the roll materials to be processed.

[0041] Reference Figure 1 and Figure 2 The tensioning mechanism 3 also includes a control panel 310, which is fixedly connected to the front side of the fixed frame 301. The fixed frame 301 is electrically connected to the servo motor 203 and the electric push rod 402 respectively.

[0042] Specifically, the operation of the servo motor 203 and the electric actuator 402 can be controlled through the control panel 310. The servo motor 203 is model RS260, and the electric actuator 402 is model YG150.

[0043] Working principle: When using this device, the take-up rollers 7 of the rolls to be bonded are first placed in their respective positions. Then, the servo motor 203 drives the cylindrical gear 204 to rotate, and the rack 206 meshing with it moves inside the corresponding limiting groove 205. The U-shaped block 207 connected to the rack 206 moves along with it, thereby driving the connecting plates 5 on both sides to move towards the middle until the two ends of the take-up rollers 7 contact the inside of the corresponding grooves 6. Then, one end of the different rolls on the two take-up rollers 7 passes through the rotating roller 309. Then it passes between the first flattening roller 404 and the second flattening roller 405. At this time, the electric push rod 402 can drive the first flattening roller 404 to move downward to squeeze the roll material. Finally, it is connected to the external winding equipment. Then, the external winding equipment can be started to perform bonding work on different roll materials. When the roll material on the winding roller 7 is used up, the above steps can be reversed to remove the winding roller 7. Disassembling and replacing the winding roller 7 is relatively simple, which can improve the bonding efficiency of subsequent roll materials and meet the needs of users.

[0044] Before the bonding process begins, since the two take-up rollers 7 rotate in opposite directions, rotating the rotating rod 305 will cause the outer drive bevel gear 306 to rotate as well, and the driven bevel gear 307 meshing with it will also rotate, thereby driving the bidirectional screw 303 to rotate. At this time, the U-shaped plates 308 on the upper and lower sides of the outer wall of the bidirectional screw 303 will move towards the center, and the rotating roller 309 inside the U-shaped plate 308 will move accordingly, which can squeeze the roll material on the corresponding take-up roller 7, so that it can always be in a taut state during the conveying process, thereby ensuring the bonding effect of the subsequent roll material.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
