Description

Technical Field

[0001] This utility model relates to the field of rubber processing, specifically a rubber cutting machine. Background Technology

[0002] Rubber is a polymer compound with excellent elasticity, insulation, water impermeability, and air impermeability, and is widely used in various aspects of industry and daily life. Rubber is mainly divided into two categories: natural rubber and synthetic rubber. Natural rubber is made by extracting latex from plants such as rubber trees and rubber grass, while synthetic rubber is obtained through polymerization reactions of various monomers.

[0003] Cutting is a crucial step in rubber production. Its main purpose is to process raw rubber into the required shapes and sizes for subsequent processing or assembly. The cutting process must ensure product precision and quality while minimizing material waste.

[0004] Existing rubber cutting machines typically cut rubber to a fixed length using a reciprocating blade. However, during production and observation, it has been found that this cutting method tends to cause a large amount of rubber to accumulate around the blade, which in turn affects the machine's ability to collect the rubber.

[0005] Therefore, a rubber cutting machine is proposed to address the above problems. Utility Model Content

[0011] Preferably, mounting plates are symmetrically bolted to the inner sidewall of the frame; a pressure roller is rotatably connected between a pair of mounting plates; the pressure roller is located on top of the transport roller; when the transport roller transports the rubber, the rubber passes over the pressure roller during its movement, and the pressure roller squeezes the surface of the rubber to improve the flatness of the rubber surface and reduce the interference of surface bending, wrinkles, etc. on the cutting quality.

During operation, the operator can place the rubber material on top of the transport roller 14 and start the device. After the device is started, the transport roller 14 will rotate and transmit the rubber, which will move to the bottom of the blade 13. Subsequently, the cylinder 12 will continuously control the blade 13 to move upwards. The downward movement causes the blade 13 to repeatedly cut the rubber. The cut rubber falls onto the surface of the air plate 15. The operator can connect an external air pump to the air pipe 16 to allow gas to enter the air plate 15 through the air pipe 16. The airflow will spray out from the holes on the surface of the air plate 15 and impact the rubber. Under the impact of the gas and the subsequent squeezing of the cut rubber, the rubber will accelerate and slide off the surface of the air plate 15. The operator can set a corresponding collection device at the bottom of the air plate 15 to collect the rubber. By setting up the air plate 15, the cut rubber will quickly detach from the surface of the air plate 15 under the impact of the gas, reducing the accumulation of rubber at the blade 13 and improving the convenience of rubber collection.

[0026] Please see Figures 1 to 4 As shown, a vertical plate 2 is symmetrically fixed to the middle of the frame 1; a guide plate 22 is rotatably connected to the middle of the vertical plate 2; a screw 23 is threadedly connected to the middle of the guide plate 22; the screw 23 and the vertical plate 2 are rotatably connected; when the rubber reaches the surface of the air plate 15, the rubber will contact the guide plate 22 and move along the surface of the guide plate 22. Because the two guide plates 22 are symmetrically arranged, the rubber will be in the central area of ​​the air plate 15 under the guidance of the guide plate 22 during the falling process. At the same time, when cutting rubber of different widths... The operator can rotate the screw 23 to make the guide plate 22 rotate along the vertical plate 2, so as to quickly adjust the distance between the pair of guide plates 22. By setting the guide plate 22, the rubber can slide out from the center of the air plate 15 under the guidance of the guide plate 22, so as to guide the movement path of the rubber and improve the convenience of rubber collection. At the same time, by setting the screw 23, rotating the screw 23 can guide the guide plate 22 to cut rubber of different widths, thereby improving the adaptability of the guide plate 22 to the processing of rubber of various widths.

[0027] Please see Figure 4As shown, a guide plate 3 is fixed to the top of the guide plate 22; the guide plate 3 has an arc-shaped structure; the guide plate 3 is located on the top of the air plate 15; some gas will reach the surface of the guide plate 22 after being sprayed out from the surface of the air plate 15. This gas will reach the inner wall of the guide plate 3 and flow back under the guidance of the contour of the guide plate 3. The flow-back gas will reach the rubber surface and clean the rubber surface, reducing the dust and impurities attached to the rubber surface.

[0028] Please see Figure 4 As shown, the bottom of the guide plate 22 is rotatably connected to a ball bearing 4; the ball bearing 4 is equidistantly arranged; when the operator adjusts the guide plate 22 by means of the screw 23, the guide plate 22 will rotate along the surface of the air plate 15 and the frame 1, and the ball bearing 4 will also come into contact with it and rotate, reducing the friction between the guide plate 22 and the air plate 15 and the frame 1.

[0029] Please see Figure 5 As shown, mounting plates 5 are symmetrically bolted to the inner sidewall of the frame 1; a pressure roller 52 is rotatably connected between a pair of mounting plates 5; the pressure roller 52 is located on top of the transport roller 14; when the transport roller 14 transports the rubber, the rubber will pass through the pressure roller 52 during the movement, and the pressure roller 52 will squeeze the surface of the rubber to improve the flatness of the rubber surface and reduce the interference of the rubber surface bending, wrinkles and other conditions on the cutting quality. At the same time, because the mounting plate 5 and the frame 1 are bolted together, the operator can adjust the height of the pressure roller 52 according to the specific thickness of the rubber to adapt to the production needs of cutting rubber of different thicknesses.

[0030] Please see Figure 5 As shown, a connecting frame 6 is fixed between a pair of mounting plates 5; a sponge 62 is fixed to the bottom of the connecting frame 6; when the rubber is squeezed and flattened by the pressure roller 52, the rubber will continue to be transported and reach the bottom of the connecting frame 6. The sponge 62 will clean the surface of the rubber, reduce the impurities attached to the surface of the rubber, and reduce the wear caused by impurities when the blade 13 cuts the surface of the rubber.

[0031] Working principle: The operator places the rubber material on top of the conveyor roller 14 and starts the device. Once started, the conveyor roller 14 rotates, driving the rubber to the bottom of the cutter 13. The cylinder 12 then continuously moves the cutter 13 up and down, repeatedly cutting the rubber. The cut rubber falls onto the surface of the air plate 15. The operator connects an air pump to the air pipe 16, allowing air to enter the air plate 15. The airflow exits from the holes on the surface of the air plate 15, impacting the rubber and causing it to... Under the impact of gas and the subsequent squeezing of the cut rubber, it accelerates and slides off the surface of the air plate 15. Workers can set up a collection device at the bottom of the air plate 15 to collect this rubber. When the rubber reaches the surface of the air plate 15, it contacts the guide plate 22 and moves along its surface. Because the guide plates 22 are symmetrically arranged, the rubber, guided by the guide plates 22, will remain in the central area of ​​the air plate 15 during its descent. Simultaneously, when cutting rubber of different widths, workers can rotate the screw 23 to guide the guide plate 22 along its vertical direction. Plate 2 rotates to quickly adjust the distance between a pair of guide plates 22; some gas is ejected from the surface of air plate 15 and reaches the surface of guide plate 22. This gas reaches the inner wall of air guide plate 3 and flows back under the guidance of the contour of air guide plate 3. The flowing gas reaches the rubber surface and cleans the rubber surface; when the operator adjusts the guide plate 22 through screw 23, the guide plate 22 will rotate along the surface of air plate 15 and frame 1, and the ball bearing 4 will also contact and rotate with it, reducing the distance between the guide plate 22 and air plate 15 and frame 1. Friction effect; when the conveyor roller 14 transports the rubber, the rubber will pass through the pressure roller 52 during the movement. The pressure roller 52 will squeeze the surface of the rubber, improve the flatness of the rubber surface, and reduce the interference of the rubber surface bending, wrinkles and other conditions on the cutting quality. At the same time, because the mounting plate 5 and the frame 1 are bolted together, the operator can adjust the height of the pressure roller 52 according to the specific thickness of the rubber. After the rubber is squeezed and flattened by the pressure roller 52, the rubber will continue to be transported and reach the bottom of the connecting frame 6. The sponge 62 will clean the surface of the rubber to reduce the impurities attached to the surface of the rubber.
