Description

Technical Field

[0001] This utility model relates to the field of adhesive bonding equipment technology, and in particular to a PVC film adhesive bonding device. Background Technology

[0002] The main component of PVC film is polyvinyl chloride. Polyvinyl chloride has a slightly yellowish, translucent appearance with a glossy sheen. Its transparency is better than that of polyethylene and polypropylene, but worse than that of polystyrene. Depending on the amount of additives used, it is divided into soft and rigid PVC. Soft PVC is flexible and tough, and has a sticky feel, while rigid PVC has a higher hardness than low-density polyethylene.

[0003] During the bonding process between PVC film and substrate, dust, oil, or small particles often adhere to the surface of the substrate. If these are not cleaned before bonding, problems such as air bubbles, delamination, or poor adhesion between the PVC film and substrate will occur, seriously affecting product quality. However, current PVC film bonding devices are not convenient for cleaning the substrate. Therefore, in order to solve the above defects, the inventors propose a PVC film bonding device.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] This utility model discloses a PVC film pasting device, such as Figures 1-6 As shown, the system includes a workbench 1 and a roller conveyor 2 mounted on the top surface of the workbench 1. The roller conveyor 2 is powered by an external power source. When the roller conveyor 2 is powered on, the motor of the roller conveyor 2 drives the sprocket on the drive roller shaft to rotate through the chain. The drive roller then drives the driven roller to rotate synchronously through the chain connection with the driven roller, thereby moving the substrate placed on the roller conveyor 2.

[0024] A cleaning rack 3 is fixedly installed on the top left side of the workbench 1, and a roller conveyor 2 is located below the cleaning rack 3.

[0025] The inner top surface of the cleaning rack 3 is slidably connected to two movable rods 301. The two movable rods 301 can slide up and down, and the bottom ends of the two movable rods 301 are fixedly installed with a first connecting frame 303. The first connecting frame 303 can be raised and lowered by the two movable rods 301 that can slide up and down.

[0026] The brush roller 305 is rotatably connected inside the first connecting frame 303, and the first motor 304 is fixedly installed on one side of the outer surface of the first connecting frame 303. The output shaft of the first motor 304 passes through the first connecting frame 303 and is fixedly connected to the brush roller 305. The first motor 304 is powered by an external power source. When the first motor 304 is powered on, it can drive the brush roller 305 to rotate.

[0027] Two first springs 302 are fixedly installed on the inner top surface of the cleaning rack 3, and the two first springs 302 are respectively sleeved on the outer ends of the two movable rods 301 and fixedly connected to the first connecting frame 303.

[0028] When the roller conveyor 2 transports the substrate to the bottom of the cleaning rack 3, the substrate will move to the bottom of the brush roller 305. The brush roller 305 can contact the substrate through the elasticity of the first spring 302. Then the first motor 304 drives the brush roller 305 to rotate, and the brush roller 305 can wipe the surface of the substrate.

[0029] An air pump 306 is fixedly installed on one side of the outer surface of the cleaning rack 3. The air pump 306 is powered by an external power source. When the air pump 306 is powered on and started, the motor of the air pump 306 drives the impeller to rotate at high speed. The gas inside the impeller rotates synchronously with the blades and moves towards the edge of the impeller under the action of centrifugal force. The speed and pressure increase. After the high-speed gas enters the volute, the flow velocity decreases due to the gradual expansion of the flow cross-sectional area. The kinetic energy is converted into static pressure energy and finally high-pressure gas is discharged from the outlet.

[0030] Furthermore, an air supply pipe 307 is fixedly installed at the outlet of the air pump 306. The air supply pipe 307 extends into the interior of the cleaning rack 3 and is equipped with multiple air jets 308. An air inlet pipe 309 is fixedly installed at the inlet of the air pump 306. After the substrate is wiped by the brush roller 305, it will move to the area below the multiple air jets 308. The high-pressure gas generated by the air pump 306 will enter the air jets 308 through the air supply pipe 307 and be sprayed out through the multiple air jets 308, so that the high-pressure gas is sprayed onto the surface of the substrate. This, in conjunction with the brush roller 305, cleans the impurities on the surface of the substrate. An adhesive assembly for pasting PVC film is provided on one side of the top surface of the workbench 1.

[0031] Two cylinders 7 are fixedly installed on the top surface of the workbench 1. A double solenoid valve, such as a two-position five-way valve, is used to control the two cylinders 7 in parallel. The cylinders 7 are driven by the synchronous movement of the valve core.

[0032] Furthermore, the output ends of the two cylinders 7 are fixedly installed with the glue application tank 4. The two cylinders 7 can push the glue application tank 4 to rise and fall, so as to adjust the height of the glue application tank 4. The glue application tank 4 is filled with chloroacetic acid glue. In actual work, different glue liquids can be replaced as needed. The top surface of the glue application tank 4 is hinged with a sealing door to prevent external impurities from entering the glue application tank 4.

[0033] Multiple glue-dispensing pipes 401 with valves are fixedly installed on the outer bottom surface of the glue-dispensing tank 4. An applicator roller 402 is rotatably connected to the outer bottom surface of the workbench 1. When the valve of the dispensing roller is opened, the glue liquid in the glue-dispensing tank 4 will fall onto the surface of the applicator roller 402 through the glue-dispensing pipes 401.

[0034] When the cleaned substrate moves to the bottom of the coating roller 402 and comes into contact with the coating roller 402, the friction generated between the substrate and the coating roller 402 as the substrate moves will cause the coating roller 402 to rotate, thereby applying the adhesive on the surface of the coating roller 402 to the surface of the substrate.

[0035] The adhesive assembly includes a fixed frame 5 that is fixedly installed on one side of the top surface of the workbench 1. The outer top surface of the fixed frame 5 is rotatably connected to an air expansion shaft 501 for winding PVC film. The air expansion shaft 501 clamps the core through pneumatic expansion and uses the friction between the air bag and the core to achieve synchronous rotation. Combined with tension control and air pressure adjustment, the stable and efficient winding of PVC film is completed.

[0036] A second motor 502 is fixedly installed on one side of the outer top surface of the fixed frame 5, and the output shaft of the second motor 502 is fixedly connected to the air expansion shaft 501. The second motor 502 drives the air expansion shaft 501 to rotate, which can realize the winding or unwinding of the PVC film.

[0037] Two guide rods 503 are slidably connected to the inner top surface of the fixed frame 5, and a connecting block 505 is fixedly installed at the bottom end of each of the two guide rods 503. The two connecting blocks 505 are rotatably connected to a limit roller 506. Two second springs 504 are fixedly installed on the inner top surface of the fixed frame 5, and the two second springs 504 are respectively sleeved on the outer ends of the two guide rods 503 and fixedly connected to the two connecting blocks 505 respectively.

[0038] One end of the PVC film is pulled below the limiting roller 506. Under the action of the second spring 504, the limiting roller 506 will press the PVC film down to contact the driven roller of the roller conveyor 2. When the substrate after applying the adhesive moves below the limiting roller 506, it will first contact the PVC film. As the substrate continues to move, the limiting roller 506 can be lifted up, so that the PVC film is between the limiting roller 506 and the substrate. At this time, the second motor 502 drives the air shaft 501 to rotate, releasing the PVC film. Then, as the substrate moves, the PVC film can be pasted onto the substrate.

[0039] A first electric slide rail 507 is fixedly installed on one side of the outer surface of the workbench 1, and a second electric slide rail 508 is fixedly installed on the slider of the first electric slide rail 507. A blade 509 is fixedly installed on the slider of the second electric slide rail 508. Both the first electric slide rail 507 and the second electric slide rail 508 are powered by an external power source, which can adjust the height and lateral position of the blade 509. When the blade 509 moves along the second electric slide rail 508, the PVC film can be cut to complete the bonding of the substrate.

[0040] A support frame 6 is fixedly installed on the right side of the top surface of the workbench 1. Two telescopic rods 601 are fixedly installed on the inner top surface of the support frame 6, and a second connecting frame 603 is fixedly installed at the bottom end of the two telescopic rods 601. A pressing roller 604 is rotatably connected inside the second connecting frame 603. An electric push rod 602 is fixedly installed on the outer top surface of the support frame, and the output end of the electric push rod 602 passes through the support frame 6 and is fixedly connected to the second connecting frame 603. The electric push rod 602 is powered by an external power source and can push the second connecting frame 603 to rise and fall, thereby adjusting the height of the pressing roller 604.

[0041] When the substrate with the PVC film attached moves to the bottom of the support frame 6, the electric push rod 602 pushes the second connecting frame 603 down, so that the pressing roller 604 contacts the PVC film on the top surface of the substrate. The downward pressure applied to the pressing roller 604 by the electric push rod 602 makes the PVC film stick tightly to the surface of the substrate.

[0042] The working principle of this utility model is as follows: The roller conveyor 2 is started, and the substrate is placed on the roller conveyor 2 in sequence. When the roller conveyor 2 transports the substrate to the bottom of the cleaning rack 3, the substrate will move to the bottom of the brush roller 305. The brush roller 305 can contact the substrate through the elasticity of the first spring 302. Then the first motor 304 drives the brush roller 305 to rotate, and the brush roller 305 can wipe the surface of the substrate. The high-pressure gas generated by the air pump 306 will enter the air nozzle 308 through the air pipe 307 and be sprayed out through multiple air nozzles 308, so that the high-pressure gas is sprayed onto the surface of the substrate, thereby working with the brush roller 305 to clean the impurities on the surface of the substrate.

[0043] The operator manually opens the valve of the feeding roller, and the adhesive in the coating tank 4 falls through the dispensing tube 401 onto the surface of the coating roller 402. When the cleaned substrate moves to the bottom of the coating roller 402 and comes into contact with it, the friction generated between the substrate and the coating roller 402 causes the coating roller 402 to rotate, thereby applying the adhesive on the surface of the coating roller 402 onto the surface of the substrate.

[0044] When the substrate after applying the adhesive moves to below the limiting roller 506, it will first come into contact with the PVC film. As the substrate continues to move, the limiting roller 506 can be lifted up, so that the PVC film is between the limiting roller 506 and the substrate. At this time, the second motor 502 drives the air shaft 501 to rotate, releasing the PVC film. Then, as the substrate moves, the PVC film can be pasted onto the substrate.

[0045] Then, when the blade 509 moves along the second electric slide rail 508, it can cut off the excess PVC film to complete the substrate bonding. When the substrate with the PVC film bonded moves to the bottom of the support frame 6, the electric push rod 602 pushes the second connecting frame 603 down, so that the pressing roller 604 contacts the PVC film on the top surface of the substrate. The downward pressure applied to the pressing roller 604 by the electric push rod 602 makes the PVC film tightly bonded to the substrate surface.
