Description

Technical Field

[0001] The invention belongs to the field of rubber product production, and in particular relates to a laser cutting device for rubber product production. Background Art

[0002] Rubber products are widely used in modern life. They are made of natural rubber or synthetic rubber and made into different products through various processing techniques. Rubber has excellent elasticity and recovery, wear resistance, impact resistance and chemical corrosion resistance. At the same time, rubber also has the disadvantages that natural rubber is easily affected by climate and ultraviolet rays and ages quickly, and synthetic rubber may burden the environment.

[0003] The cutting of rubber products is an important part of the manufacturing and processing process, involving a variety of technologies and tools to ensure that the rubber material is accurately and efficiently processed into the required shape and size. These include manual cutting, mechanical cutting and CNC cutting. Mechanical cutting includes punching, laser, water jet and circular knife cutting. The following is a specific introduction to laser cutting.

[0004] Laser Cutting Principle: Precise cutting of rubber materials by laser beam; Applicable scenarios: Suitable for cutting with complex shapes and high precision requirements; Advantages: high cutting accuracy, smooth edges, suitable for complex patterns; Disadvantages: High equipment cost, slow cutting speed, suitable for thinner materials.

[0005] Existing publication number CN207495851U discloses a cutting device for rubber product production, including a hollow cutting table, the middle of the two sides of the top of the cutting table are connected to the same portal frame by bolts, the top of the portal frame is provided with four evenly distributed mounting holes, and the tops of the mounting holes on both sides are connected to vertical hydraulic cylinders by bolts, the insides of the two mounting holes in the middle are both plugged with vertical cooling inner tubes, the top pipe openings of the two cooling inner tubes are both threadedly connected to hoses, the bottoms of the two hydraulic cylinder piston rods are connected to the same cutting knife by bolts, the top of the cutting knife is provided with a cooling channel, and the two openings of the cooling channel are both threadedly connected to cooling outer tubes.

[0006] The existing laser cutting devices for rubber product production still have the following shortcomings: 1. When using laser cutting on rubber products, the existing device uses a single laser emitter to cut the rubber surface. This design requires the machine to perform multiple cuts when cutting multiple parts on a large surface of rubber products, which will increase the workload of the device and affect the cutting efficiency.

[0007] 2. When using laser to cut rubber products, a large amount of smoke and irritating gases will be generated, which will affect the production environment and production personnel, and is not conducive to long-term stable production. Therefore, additional dust collection components are required during laser cutting. 3. Because the rubber surface has a certain degree of adhesion, there will be strong resistance when placing a large area of ​​rubber products on the operating platform of the device. After placement, it is not conducive to the adjustment of the position of the rubber products, and it is not convenient for the device to position the rubber products, which will affect the utilization rate of the rubber products.

The shift plate 15 penetrates and is slidably connected in the sleeve plate 18. The gear 14 is driven to rotate by the second motor 13. Since the tooth grooves 16 on the gear 14 and the shift plate 15 are meshed with each other, the two shift plates 15 can be synchronously displaced in the opposite direction during the rotation of the gear 14. The sleeve plate 18 is fixedly connected to the side surface of the shift plate 15. Since the limit plates 17 penetrate and are slidably connected in the sleeve plate 18, the stability of the transmission assembly is enhanced, and a certain supporting force can be provided during the movement of the shift plate 15.
