Description

Technical Field

[0001] This utility model relates to the field of silicone rubber cutting technology, specifically to a precision cutting machine for high tear conductive silicone rubber. Background Technology

[0002] Silicone rubber, as a high-performance polymer material, is widely used in many fields due to its excellent resistance to high and low temperatures, chemical corrosion, biocompatibility, and unique elasticity. High-tear conductive silicone rubber is a high-performance silicone rubber that not only requires good conductivity but also high tear strength to ensure the integrity and reliability of the material under complex stress environments.

[0003] After the high tear conductive silicone rubber is reprocessed, it needs to be cut into strips. The traditional cutting method is to cut the silicone rubber material between cutting blades. During the cutting process, due to the certain friction between the cutting blade and the silicone rubber, the silicone rubber is prone to shift during the cutting process, resulting in inaccurate cutting and greatly affecting product quality. At the same time, after the cutting is completed, the cut strips are stacked on the cutting table, which is inconvenient to collect. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a precision cutting machine for high tear conductive silicone rubber. It can press and fix the silicone rubber during the cutting process to prevent the cutting from deviating. After the cutting is completed, it can be quickly collected, saving time and effort.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a precision cutting machine for high tear conductive silicone rubber, comprising a machine base, a support leg fixedly connected to the bottom surface of the machine base, a cutting frame fixedly connected to the upper end of the machine base, a material conveying mechanism provided on one side of the cutting frame on the machine base, side plates fixedly connected to both sides of the machine base, a discharge table slidably connected between the two side plates at one end of the machine base, pulleys rotatably connected to the four corners of the discharge table, and the inner wall of the side plates having correspondingly arranged length-... The guide slide holes are arranged in a certain direction, and one end of each guide slide hole on both sides is provided with an arc-shaped turning hole. An adjusting cylinder is hinged between the support leg and the guide slide plate. A cutting box is provided inside the cutting machine frame. The lower end of the cutting box is an open end. A cutting cylinder that drives the cutting box to slide up and down is fixedly connected to the cutting machine frame. L-shaped pressure plates are slidably inserted into both sides inside the cutting box. A compression spring is fixedly connected between the upper end of the cutting box and the L-shaped pressure plate. A cutting mechanism is provided inside the cutting box between the two L-shaped pressure plates.

A movable screw is rotatably connected inside the cutting box. A motor that drives the movable screw to rotate is fixedly connected to one end of the cutting box. A cutting tool is fixedly connected to the lower end of the movable block.

[0007] As an improvement, an electric push rod is fixedly connected to the upper end of the unloading platform, and an unloading push plate is fixedly connected to the output end of the electric push rod.

[0008] As an improvement, a receiving box is provided on the bottom surface of the machine.

[0009] As an improvement, the L-shaped pressure plate is fixedly connected to limit blocks at both ends, and the inner walls on both sides of the cutting box are provided with limit grooves that cooperate with the limit blocks.

[0010] The advantages of this utility model compared with the prior art are as follows:

[0020] The cutting frame 3 is equipped with a cutting box 13, the lower end of which is open. A cutting cylinder 14 is fixedly connected to the cutting frame 3 to drive the cutting box 13 to slide up and down. L-shaped pressure plates 19 are slidably inserted into both sides of the cutting box 13. Limiting blocks are fixedly connected to both ends of the L-shaped pressure plates 19. Limiting grooves that cooperate with the limiting blocks are provided on the inner walls of both sides of the cutting box 13.

A cutting mechanism is provided in the cutting box 13 between the two L-shaped pressure plates 19. The cutting mechanism includes a moving block 15 slidably connected to the upper end of the cutting box 13 and located between the two L-shaped pressure plates 19.

A cutting blade 18 is fixedly connected to the lower end of the moving block 15.

[0021] In practical use, the silicone rubber sheet is placed on the material conveying mechanism 2 and conveyed into the cutting frame 3. When cutting is required, the material conveying mechanism 2 is closed, and the cutting cylinder 14 is activated to push the cutting box 13 downward, so that the two L-shaped pressure plates 19 first contact the silicone rubber sheet downward, causing the L-shaped pressure plates 19 on both sides to slide into the cutting box 13, causing the compression spring 20 to be compressed and deformed. At the same time, the cutting blade 18 penetrates the silicone rubber. The motor 16 is activated to drive the moving screw 17 to rotate, and the moving screw 17 drives the moving block 15 to move the cutting blade 18 along the length of the cutting box 13. The material is slidable to cut the silicone rubber. After cutting, the material conveying mechanism 2 continues to convey the silicone rubber and pushes the cut material onto the unloading platform 6. The adjusting cylinder 7 is activated to push the unloading platform 6 to slide along the guide sliding holes 9 on both sides. The guide sliding holes 9 on both sides are parallel to the end face of the machine base 1, so that one end of the unloading platform 6 is away from the cutting frame 3. When the two pulleys 8 at one end slide into the arc-shaped turning sliding hole 10, one end of the unloading platform 6 tilts upward and is in an inclined state. The electric push rod 11 is activated to push the push plate 12 to push the material downward and let the material fall into the receiving box 21 for collection.
