Description

Technical Field

[0001] This utility model belongs to the field of rubber product processing technology, and in particular relates to an automatic cutting and coating machine for manufacturing rubber products. Background Technology

[0002] In the manufacturing process of rubber, an automatic cutting and laminating machine is needed to coat rubber products. The laminating machine is a device that can coat films such as polyester film, aluminized film or polyolefin film to form film rolls.

[0003] In order to prevent dust and debris from contaminating the surface of the products to be processed, existing automatic cutting and laminating machines are usually equipped with dust covers during use. However, the laminating machine is covered inside for dust-free processing. But during the processing, it is usually necessary to open the dust cover. When the dust cover is opened, dust will enter the dust cover and affect the processing of the laminating machine.

[0004] In addition to the dust removal structure mentioned above, some laminating machines require a rotating dust removal roller to remove dust and impurities from the rubber surface. The dust stuck to the surface of the dust removal roller is then removed by the dust-adhesive roll, thus achieving dust removal. However, users need to regularly disassemble and replace the dust-adhesive roll to ensure the efficiency of the equipment's dust removal, which is too cumbersome and inconvenient. Summary of the Invention

[0005] The purpose of this utility model is to provide an automatic cutting and laminating machine for manufacturing rubber products. This automatic cutting and laminating machine uses high-pressure air to gradually remove dust during the laminating process, which improves dust removal efficiency and avoids the need to replace too many structures, thereby improving overall processing efficiency. In addition, the overall laminating process is highly automated, reducing labor costs.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic cutting and coating machine for manufacturing rubber products includes a base, a conveyor belt fixed on the base, a coating take-up roller located above the conveyor belt, a transverse drive unit connected to the coating take-up roller, the transverse drive unit driving the coating take-up roller to move along the length direction of the conveyor belt, a vertically moving extrusion cutting roller located on one side of the coating take-up roller, a coating traction unit located between the extrusion cutting roller and the coating take-up roller, and a dust blowing and cleaning unit fixed on the base, the dust blowing and cleaning unit including an air guide plate fixed on the base, the air guide plate being located above the conveyor belt.

[0008] Furthermore, the lateral drive component includes a bracket fixed on the base, guide rods fixed between the brackets, the guide rods being symmetrically arranged, a first support frame being slidably connected between two guide rods, a film-coating take-up roller being elastically rotatably connected inside the first support frame, and a first cylinder being fixed on the side of the first support frame, the first cylinder being fixed inside the bracket.

[0009] Furthermore, the extrusion cutting roller is provided with a second support frame at both ends, and the extrusion cutting roller is rotatably connected inside the second support frame. Annular cutting blades are fixed on the side of the extrusion cutting roller, and the annular cutting blades are symmetrically arranged. Two annular cutting blades are positioned close to both ends of the extrusion cutting roller. A piston rod is connected to the top of the second support frame, and a second cylinder is connected to the end of the piston rod away from the second support frame. The piston rod is rotatably connected inside the support frame.

[0010] Furthermore, the film-coating traction component includes a support rod fixed on the base, a slide rail fixed at the end of the support rod away from the base, a sliding block slidably connected inside the slide rail, an adhesive head fixed at the front end of the sliding block, and an adjustment block fixed at the rear end of the sliding block.

[0011] Furthermore, the adjusting block is internally threaded with a lead screw, and fixed blocks are provided at both ends of the lead screw. The lead screw is rotatably connected inside the fixed blocks, and both fixed blocks are fixed to the side of the slide rail. The lead screw extends out along the end face of one of the fixed blocks, and the extended end is connected to a motor.

[0012] Furthermore, an air outlet is fixed to the end of the air guide plate facing the conveyor belt, and an air outlet is provided at the end of the air outlet plate away from the air guide plate.

[0013] In summary, the beneficial technical effects of this utility model are as follows:

[0014] 1. This automatic cutting and laminating machine uses high-pressure air to gradually remove dust during the laminating process, which improves dust removal efficiency and avoids the use of too many structures that need to be replaced, thereby improving overall processing efficiency;

[0015] 2. During the lamination process, the rubber products move forward automatically, and while laminating gradually, excess film can be cut off. The overall lamination process is highly automated, reducing labor costs.

[0016] 3. Adhesive heads are used. Two opposite adhesive heads can be bonded to the end of the film coating. As the sliding block carries the adhesive heads toward the end of the extrusion and cutting roller, the film wrapped around the outside of the film coating take-up roller can be pulled and moved automatically. The width of the two adhesive heads is greater than that of the extrusion and cutting roller, so the film tension is guaranteed and the degree of adhesion after film coating is improved.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] 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.

[0024] Please see Figure 1-3 This utility model provides a technical solution: an automatic cutting and coating machine for manufacturing rubber products, including a base 1, a conveyor belt 2 fixed on the base 1, a coating and winding roller 3 located above the conveyor belt 2, the coating and winding roller 3 being connected to a transverse drive member, the transverse drive member driving the coating and winding roller 3 to move along the length direction of the conveyor belt 2, a vertically moving extrusion cutting roller 4 located on one side of the coating and winding roller 3, a coating traction member being provided between the extrusion cutting roller 4 and the coating and winding roller 3, and a dust blowing and cleaning member fixed on the base 1, the dust blowing and cleaning member including an air guide plate 5 fixed on the base 1, the air guide plate 5 being located above the conveyor belt.

[0025] Specifically, the lateral drive component includes a bracket 6 fixed on the base 1, guide rods 7 fixed between the brackets 6, the guide rods 7 are symmetrically arranged, a first support frame 8 is slidably connected between the two guide rods 7, the first support frame 8 is elastically rotatably connected to the film-coating take-up roller 3 inside, and a first cylinder 9 is fixed on the side of the first support frame 8, the first cylinder 9 is fixed inside the bracket 6.

[0026] In this embodiment, the elastic rotation is achieved by a torsion spring structure. Torsion springs are provided at both ends of the film-coating take-up roller 3, so that the film-coating take-up roller 3 can rotate automatically.

[0027] The first cylinder 9 can drive the first support frame 8 to slide along the two guide rods 7, thereby driving the film-coating take-up roller 3 inside the first support frame 8. The required film is wound around the outside of the film-coating take-up roller 3. As the film is used continuously, the overall radius of the film winding continuously decreases. In order to facilitate its proximity to the film-coating traction component below, the position of the film-coating take-up roller 3 can be adjusted by driving the first cylinder 9 to avoid the film being too far away from the film-coating traction component, which would increase the possibility of dust adhesion.

[0028] The extrusion cutting roller 4 has a second support frame 10 at both ends. The extrusion cutting roller 4 is rotatably connected inside the second support frame 10. The side of the extrusion cutting roller 4 is fixed with annular cutting blades 11. The annular cutting blades 11 are symmetrically arranged. Two annular cutting blades 11 are arranged close to both ends of the extrusion cutting roller 4. The top of the second support frame 10 is connected to a piston rod 12. The end of the piston rod 12 away from the second support frame 10 is connected to a second cylinder 13. The piston rod 12 is rotatably connected inside the bracket 6.

[0029] The second cylinder 13 can drive the second support frame 10 to move up and down. When driving the second support frame 10 to move up and down, the distance between the extrusion cutting roller 4 inside the second support frame 10 and the top of the conveyor belt 2 can be changed, thus making it suitable for rubber products such as rubber sheets of different thicknesses.

[0030] The film-coating traction component includes a support rod 14 fixed on the base 1, a slide rail 15 fixed at the end of the support rod 14 away from the base 1, a sliding block 16 slidably connected inside the slide rail 15, an adhesive head 17 fixed at the front end of the sliding block 16, and an adjustment block 18 fixed at the rear end of the sliding block 16.

[0031] The adjusting block 18 is internally threaded with a lead screw 19. The lead screw 19 has fixed blocks 20 at both ends. The lead screw 19 is rotatably connected inside the fixed blocks 20. Both fixed blocks 20 are fixed to the side of the slide rail 15. The lead screw 19 extends along the end face of one of the fixed blocks 20, and the extended end is connected to a motor 21.

[0032] The motor 21 can drive the lead screw 19 to rotate. As the lead screw 19 rotates, the adjusting block 18, which is threadedly connected to the lead screw 19, can drive the sliding block 16 to move inside the slide rail 15. By controlling the rotation direction of the motor 21, the sliding block 16 can reciprocate inside the slide rail 15.

[0033] The sliding block 16 has an adhesive head 17 fixed at its front end. Two opposing adhesive heads 17 can be bonded to the end of the film coating. As the sliding block 16 moves towards the end of the extrusion and cutting roller 4 with the adhesive heads 17, it can pull the film wrapped around the outside of the film coating take-up roller 3 to move. The film coating take-up roller 3 rotates accordingly. In this embodiment, the sliding block 16 can move to a position below the extrusion and cutting roller 4 at its furthest point, thereby placing the end of the film coating below the extrusion and cutting roller 4. As the rubber plate moves, the film coating can be squeezed onto the rubber plate by the extrusion and cutting roller 4. At the same time, the excess film coating in the width direction is cut by the annular cutting blade 11. After the rubber plate moves as a whole past the extrusion and cutting roller 4, the film coating can be cut manually for further processing.

[0034] An air outlet 22 is fixed to the end of the air guide plate 5 facing the conveyor belt 2. An air outlet 23 is provided at the end of the air outlet 22 away from the air guide plate 5. The air outlet 23 is arranged parallel to the conveyor belt 2. An air inlet pipe 24 is fixedly connected to one end of the air guide plate 5. An external air supply device is connected to the air inlet pipe 24. The external air supply device may include a blower. After the blower is connected, air is introduced into the air guide plate 5. The air is squeezed and blown out along the air outlet 23, thereby providing high-pressure air force to the surface of the rubber plate below and blowing away the surface dust.

[0035] The working principle of this utility model is as follows: The rubber sheet is placed on the conveyor belt 2. As the conveyor belt 2 rotates, it first passes through the air outlet 23. The dust on the surface of the rubber sheet is gradually blown off after passing through the air outlet 23. Then, it passes through the extrusion and cutting roller 4. During the movement of the rubber sheet, the motor 21 drives the sliding block 16 to move. The sliding block 16 moves to the side of the film-coating take-up roller 3, and then contacts the end of the film roll wound on the film-coating take-up roller 3 through the adhesive head 17, thus adhering the film. The movement of the sliding block 16 carries the film to a position below the extrusion and cutting roller 4, where it contacts the surface of the rubber sheet. As the extrusion and cutting roller 4 contacts the rubber sheet, the rubber sheet continues to move. Since the extrusion and cutting roller 4 is fixed in its vertical position, it rotates as the rubber sheet moves. The annular cutting blade 11 rotates, continuously pressing the film against the rubber plate while cutting off excess film on both sides. The excess film is fixed by the adhesive head 17. At this time, the sliding block 16 remains fixed. As the film is applied, the film winding roller 3 rotates under the pull of the film, continuously releasing the film. After the entire rubber plate passes through the squeezing cutting roller 4, it is in a complete applied state. The middle of the film and the film strips adhered to the adhesive head 17 are cut manually. As the film winding roller 3 rotates, its end moves again to the side of the film winding roller 3. Then, the motor 21 is controlled again to drive the sliding block 16 to move to the slide rail 15 near the side of the film winding roller 3, and the film is applied to the next rubber plate. This process is repeated. Only one person is needed to operate the whole cutting and filming machine, reducing labor costs.
