Description

Technical Field

[0001] This utility model belongs to the field of composite PE film processing technology, specifically a bonding device for composite PE film processing. Background Technology

[0002] Polyethylene is a thermoplastic resin obtained by polymerizing ethylene. Industrially, it also includes copolymers of ethylene with small amounts of α-olefins. Polyethylene is odorless, non-toxic, and has a waxy feel. It possesses excellent low-temperature resistance, good chemical stability, and resistance to most acids and alkalis. It is insoluble in common solvents at room temperature, has low water absorption, and excellent electrical insulation. Laminating equipment for composite PE film processing is specifically designed to tightly bond multiple layers of films of different materials together through hot pressing or other methods. In practical use, most existing laminating equipment directly places the fabric on the workbench surface. During the lamination of the fabric and the composite PE film, the fabric is prone to displacement, leading to lamination errors and affecting the lamination quality. Summary of the Invention

[0003] To overcome the above-mentioned defects, this utility model provides a bonding device for processing composite PE film, which solves the problem that most devices directly place the fabric on the workbench surface, and when bonding the fabric and composite PE film, the fabric is prone to displacement, resulting in bonding errors and affecting the bonding quality.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a bonding device for processing composite PE film, comprising a worktable, a movable groove on the worktable, a bidirectional threaded rod rotatably connected to the inner wall of the movable groove, a rotating rod fixedly connected to the bidirectional threaded rod passing through the movable groove, a clamping frame externally threaded to the bidirectional threaded rod, two clamping frames, the clamping frames being slidably connected to the worktable, a pull rod mounted on the clamping frame, a connecting block fixedly connected to the pull rod, a spring disposed under the connecting block, the two ends of the spring being fixedly connected to the clamping frame and the connecting block, a pressure plate disposed under the pull rod, the pressure plate being slidably connected to the clamping frame, and two auxiliary rods fixedly connected to the pressure plate.

[0005] As a further embodiment of this utility model: a reciprocating motor is installed on one side of the worktable, and the reciprocating motor is provided with a movable wheel structure through the output shaft. A reciprocating screw is installed on one side of each of the two movable wheels in the movable wheel structure, and the reciprocating screw is rotatably connected to the worktable.

[0006] As a further embodiment of this utility model: the reciprocating screw is externally threaded with a movable frame, and an electric telescopic rod is fixedly connected to the movable frame.

[0007] As a further embodiment of this utility model: an assembly bracket is provided under the electric telescopic rod, and an output motor is slidably connected to one side of the assembly bracket.

[0008] As a further embodiment of this utility model: the output motor is equipped with a gear through the output shaft, a toothed plate is fixedly connected to the top of the assembly bracket, the toothed plate meshes with the gear, a cutting blade is provided on one side of the gear, and the cutting blade is slidably connected to the assembly bracket.

[0009] As a further embodiment of this utility model: a backing plate is installed under the assembly bracket, and a roll of PE film is rotatably connected to the assembly bracket.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This laminating device for processing composite PE film comprises a rotating rod, a bidirectional threaded rod, clamping frames, and a pressure plate. Pulling the rod causes the connecting block to rise along with it. The spring deforms as the connecting block rises. Then, the two ends of the fabric are placed on the two clamping frames. Releasing the rod allows the spring force to clamp and fix the fabric to the pressure plate. Rotating the rotating rod causes the bidirectional threaded rod to rotate, which in turn causes the two clamping frames to move away from each other, stretching the fabric to both sides to tighten it. This facilitates subsequent lamination with the composite PE film and ensures that the fabric does not shift or wrinkle during lamination.

[0012] This lamination device for processing composite PE film, equipped with an output motor, gears, a toothed plate, and a cutting blade, after laminating the fabric and composite PE film, controls an electric telescopic rod to move the assembly bracket down close to the fabric. The output motor drives the gears to rotate, and through the meshing of the gears and the toothed plate, the gears simultaneously drive the output motor and the cutting blade to slide on the assembly bracket to cut the composite PE film. At the same time, the abutment plate presses the composite PE film firmly, preventing the cutting blade from displacing the composite PE film during cutting, thereby improving the cutting quality.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-4 As shown, this utility model provides a technical solution: a bonding device for processing composite PE film, including a worktable 1, a reciprocating motor 11 installed on one side of the worktable 1, a movable wheel structure 12 provided on the output shaft of the reciprocating motor 11, and a reciprocating screw 13 installed on one side of each of the two movable wheels in the movable wheel structure 12. The reciprocating screw 13 is rotatably connected to the worktable 1. By setting the movable wheel structure 12, the reciprocating motor 11 drives the movable wheel structure 12, thereby driving the two reciprocating screws 13 to rotate simultaneously, thereby making the movable frame 14 move more smoothly.

[0020] The reciprocating screw 13 is externally threaded to a movable frame 14, and an electric telescopic rod 15 is fixedly connected to the movable frame 14. By setting the electric telescopic rod 15, the electric telescopic rod 15 drives the assembly bracket 16 to rise, thereby facilitating the replacement of the PE film on the PE film roll 22. By controlling the extension of the electric telescopic rod 15, it is convenient for the cutting blade 20 to cut the PE film.

[0021] An assembly bracket 16 is provided under the electric telescopic rod 15. An output motor 17 is slidably connected to one side of the assembly bracket 16. A gear 18 is provided on the output motor 17 through the output shaft. A toothed plate 19 is fixedly connected to the top of the assembly bracket 16. The toothed plate 19 meshes with the gear 18. A cutting blade 20 is provided on one side of the gear 18. The cutting blade 20 is slidably connected to the assembly bracket 16. A backing plate 21 is installed under the assembly bracket 16. A PE film roll 22 is rotatably connected to the assembly bracket 16. By providing the output motor 17, the output motor 17 drives the gear 18, which in turn drives the cutting blade 20 to move quickly within the assembly bracket 16, which facilitates the rapid cutting of the PE film.

[0022] The workbench 1 has a movable groove 4. A bidirectional threaded rod 3 is rotatably connected to the inner wall of the movable groove 4. A rotating rod 2 is fixedly connected to the bidirectional threaded rod 3 through the movable groove 4. A clamping frame 5 is externally threaded to the bidirectional threaded rod 3. There are two clamping frames 5. The clamping frames 5 are slidably connected to the workbench 1. A pull rod 6 is installed on the clamping frame 5. A connecting block 7 is fixedly connected to the pull rod 6. A spring 8 is set under the connecting block 7. The two ends of the spring 8 are fixedly connected to the clamping frame 5 and the connecting block 7. A pressure plate 9 is set under the pull rod 6. The pressure plate 9 is slidably connected to the clamping frame 5. Two auxiliary rods 10 are fixedly connected to the pressure plate 9. By setting the auxiliary rods 10, the pull rod 6 drives the pressure plate 9 to move up and down. The auxiliary rods 10 pass through the clamping frame 5, thereby limiting the operation of the pressure plate 9 and making the up and down movement of the pressure plate 9 more stable.

[0023] The working principle of this utility model is as follows:

[0024] In use, rotating the rotating rod 2 drives the bidirectional threaded rod 3 to rotate, causing the clamping frame 5 outside the bidirectional threaded rod 3 to move inward to a suitable position as the bidirectional threaded rod 3 rotates. Pulling the pull rod 6 causes the pull rod 6 to rise, and at the same time, it drives the spring 8 to rise through the connecting block 7. The spring 8 deforms as the pull rod 6 rises, generating corresponding pressure. Then, place the two ends of the fabric to be processed on the two clamping frames 5 respectively. Then, release the pull rod 6, so that the pull rod 6 drives the pressure plate 9 to move down with the elastic force of the spring 8 to clamp and fix the fabric. Rotating the rotating rod 2 again causes the rotating rod 2 to drive the two clamping frames 5 to move away from each other through the bidirectional threaded rod 3, and at the same time, it drives the fabric to stretch to both sides to tighten the fabric.

[0025] The electric telescopic rod 15 drives the assembly bracket 16 to move down, so that the PE film roll 22 is attached to the fabric surface. The reciprocating motor 11 is started. The reciprocating motor 11 drives the movable wheel structure 12 to rotate, which in turn drives the movable frame 14 to move, so that the PE film roll 22 is attached to the fabric. After the attachment is completed, the output motor 17 is started. The output motor 17 drives the gear 18 to rotate, so that the gear 18 drives the cutting blade 20 to cut the PE film roll 22 through the toothed engagement with the toothed plate 19.
