Description

Technical Field

[0001] This utility model relates to the field of rubber processing equipment technology, and more specifically to a shearing device used in rubber processing. Background Technology

[0002] As is well known, rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature, capable of large deformation under small external forces, and returns to its original shape after the force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and a very high molecular weight, often exceeding hundreds of thousands. In rubber processing, cutting is often required to meet subsequent production needs. Existing rubber shearing equipment uses a shearing platform + gantry structure, with shearing blade assemblies mounted on the gantry to cut rubber to different thicknesses. However, existing rubber shearing equipment has a drawback: rubber shearing typically has different shearing requirements, including shearing shape and thickness. Single-gantry shearing equipment can only perform one operation at a time, resulting in low shearing efficiency and failing to meet production demands. Furthermore, existing shearing equipment usually uses infrared positioning components on the shearing blade assembly, but rubber shearing requires secondary cutting, and the infrared positioning components on the shearing assembly cannot meet the requirements for precise positioning, thus failing to achieve accurate shearing. To address the aforementioned problems, the inventors propose a shearing device for rubber processing. This device uses a positioning device mounted on the ceiling of the shearing equipment to precisely position the rubber. Simultaneously, a double-gantry structure enables secondary shearing of the rubber, achieving a one-time forming effect and improving shearing efficiency.

[0003] To achieve automated shearing in rubber sheet processing, enabling automated conveying and cutting of rubber sheets, Chinese Patent (Authorization Announcement No.: CN215359464U) discloses a rubber sheet processing device. This utility model includes a box body and a conveyor belt running through both sides of the box body. A waste collection box is provided inside the box body, and multiple drainage holes are opened at the bottom of the waste collection box. A water tank is provided below the waste collection box, and a water pump is fixedly connected to the inner wall of the water tank. This utility model can automatically trim and cut the rubber by setting up a pressure shaft and a cutter. By setting up a conveyor belt, the rubber sheet can be automatically conveyed and cut, completing the assembly line operation. It has the advantages of saving manpower, simple structure, and low cost.

[0004] The solution still has some shortcomings in application. Due to the variety of rubber shearing patterns, multiple shearings are often required to achieve the desired shape. Therefore, it is necessary to be able to shear different thicknesses more quickly and ensure accurate positioning of the rubber during shearing to achieve precise shearing. Thus, the structure of the shearing device needs to be improved to enable precise positioning and effectively improve the quality and efficiency of rubber shearing. Utility Model Content

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0022] like Figures 1 to 5 As shown, a shearing device for rubber processing includes a shearing platform 1 and a positioning device 2. The positioning device 2 is located directly above the shearing platform 1. Frames 3 are provided on the left and right sides of the shearing platform 1. Longitudinal slide rails 4 are provided on the frame 3. A front gantry 5 and a rear gantry 6 are respectively installed between the longitudinal slide rails 4. Transverse slide rails 7 are installed on the front gantry 5 and the rear gantry 6. A cutting assembly 8 is installed on the transverse slide rails 7. The front side of the cutting assembly 8 includes an integrally connected motor 81, lead screw 82, and lifting platform 83. An infrared positioning receiver 84 is provided on the top. The positioning device 2 is provided with a plurality of infrared positioning transmitters 21, which are movably connected to the receivers 84.

[0023] Furthermore, the shearing platform 1 is equipped with a conveyor belt 9.

[0024] Furthermore, both the longitudinal slide rail 4 and the transverse slide rail 7 are electric slide rails, the front gantry 5 and the rear gantry 6 can slide back and forth along the longitudinal slide rail 4, and the cutting assembly 8 can slide left and right along the transverse slide rail 7.

[0025] Furthermore, the lifting platform 83 can move up and down by rotating the lead screw 82 driven by the motor 81, and a cutting blade 85 is installed at the bottom of the lifting platform 83.

[0026] Furthermore, the transmitter 21 is provided with a mounting bracket 22 on its top, and the transmitter 21 is equidistantly positioned above the shearing platform 1 from front to back.

[0027] Furthermore, the irradiation surface of the transmitter 21 covers the shearing platform 1.

[0028] Furthermore, a control panel 10 is provided on one side of the shearing platform 1.

[0029] Example: First, the rubber is conveyed by the conveyor belt 9 on the shearing platform 1. After conveying, it is infrared positioned by the transmitter 21 of the positioning device 2. Then, after the transmitter completes the positioning, it determines the coordinates of the first shearing and transmits the information to the control panel 10. The control panel 10 transmits the coordinate information to the receiver 84 on the cutting assembly 8. The control panel 10 first controls the rear gantry 6 to slide along the longitudinal slide rail 4 and the cutting assembly 8 to slide along the transverse slide rail 7, so that the cutting assembly 8 completes the front, back, left and right positioning. Then, the motor 81 drives the lead screw 82 to rotate, which drives the lifting platform 83 to slide downward. The cutting blade 85 at the bottom of the lifting platform 83 performs the first shearing 11 on the rubber. Then, after the first shearing is completed, the rubber continues to be conveyed forward. The transmitter is positioned again to determine the coordinates of the second shearing. After determination, the front gantry 5 performs the second shearing 12 on the rubber in the same way as above. Finally, while the front gantry 5 performs the second shearing 12, the rear gantry 6 also performs the first shearing 11 on another part of the rubber at the same time. In this way, the rubber shearing is completed.

[0030] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:

[0031] This invention firstly uses several infrared positioning transmitters positioned directly above the shearing platform to cover the entire platform, enabling precise omnidirectional positioning.

Next, the shearing platform is equipped with a front and rear gantry, each fitted with a cutting component. The cutting blades on these components are driven by a motor to move up and down, cutting materials of varying thicknesses, including rubber. Finally, the dual gantry configuration allows for secondary cutting of the rubber. Simultaneously, while the front gantry performs secondary cutting, the rear gantry performs the first cutting, improving efficiency and making this invention highly practical.
