Description

Technical Field

[0001] This utility model relates to the field of rubber product manufacturing technology, specifically to a cutting device for rubber product manufacturing. Background Technology

[0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can undergo large deformation under small external forces. It can return to its original shape after the external force is removed. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is made by extracting gum from plants such as rubber trees and rubber grass and then processing it. Synthetic rubber is obtained by polymerization reactions of various monomers. Rubber products are widely used in various aspects of industry and daily life.

[0003] When producing rubber products, they need to be cut to the required length using cutting equipment. However, the structural components of some existing cutting equipment are relatively rigid and fixed. When adjusting the cutting length, it is usually necessary to stop the machine and disassemble the cutting equipment, which is cumbersome and inconvenient and may affect the production efficiency of rubber products, thus having certain limitations.

[0018] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0019] Please see Figures 1-2 This utility model provides a cutting device for rubber product manufacturing, including a support 1. A set of mounting slots 2 are opened in the middle of the top surface of the support 1. A set of rotating wheels 3 are rotatably connected in the mounting slots 2. A set of drive motors 4 are installed at the right end of the support 1. The left end of the drive shaft of the drive motor 4 extends through the mounting slots 2 and is connected to the rotating wheels 3, which can drive the rotating wheels 3 to rotate. A set of connecting rods 5 are fixedly connected to both the left and right ends of the top surface of the support 1. A set of fixed wheels 6 are installed at the top of both sets of connecting rods 5.

[0020] Please see Figures 2-3This utility model provides a cutting device for rubber product manufacturing. A set of guide grooves 31 are provided at the middle of the outer side of each rotating wheel 3. Rubber products can be inserted into the guide grooves 31 during movement, ensuring the stability of the rubber products. A set of cutting notches 32 are provided at the outer end of the rotating wheel 3. Both ends of the cutting notches 32 are connected to the guide grooves 31, allowing the rubber products to extend into the cutting notches 32. A set of movable arms 33 are rotatably connected to both the front and left / right ends of the cutting notches 32. The middle of the opposite faces of the two sets of movable arms 33 are connected by springs 34. The two sets of movable arms 33 can rotate left and right by compressing the springs 34. A set of cutting blades 35 are installed at the rear end of each set of movable arms 33. There is a gap between the opposing surfaces of the arms 33. The blades of the two sets of cutting blades 35 extend into the gap. When the two sets of movable arms 33 compress the spring 34 and move relative to each other, the two sets of cutting blades 35 approach each other and can cut rubber products. The rear ends of the two sets of movable arms 33 extend outward to the outer end of the rotating wheel 3. During the rotation of the rotating wheel 3, the rear ends of the two sets of movable arms 33 contact the two sets of fixed wheels 6 respectively. The fixed wheels 6 can push the two sets of movable arms 33 inward to rotate. Furthermore, a set of limiting frames is provided at both ends of the cutting notch 32. The outer middle of the two sets of movable arms 33 can contact the inner side of the two sets of limiting frames. The rotation range of the movable arms 33 can be limited by the two sets of limiting frames.

[0021] The working principle is as follows:

[0022] In use, the rubber product, such as a rubber strip, is pushed by an external pushing device. During the movement of the rubber strip, it can be locked into the guide groove 31 to ensure the stability of the movement. The drive motor 4 drives the rotating wheel 3 to rotate. During the rotation of the rotating wheel 3, the rear ends of the two sets of movable arms 33 contact the left and right sets of fixed wheels 6 respectively. The two sets of fixed wheels 6 push the two sets of movable arms 33 inward to rotate relative to each other. The cutting blade 35 cuts the rubber strip located in the cutting notch 32. After the cutting is completed, the rear ends of the two sets of movable arms 33 separate from the two sets of fixed wheels 6 and return to their original position by the spring 34, which facilitates the next cutting operation. The cutting length of the rubber strip can be adjusted and controlled by adjusting the rotation speed of the rotating wheel 3, which has a flexible and controllable effect.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model.
