Description

Technical Field

[0001] The utility model relates to the technical field of rubber ring cutting, in particular to a rubber ring cutting device. Background Art

[0002] Rubber rings are resistant to oil, acid and alkali, cold and heat, and aging. They can be directly cut into sealing gaskets of various shapes and are widely used in the pharmaceutical, electronic, chemical, antistatic, flame retardant, food and other industries. Rubber rings are usually cut from rubber tubes, and the rubber tubes to be cut need to be fixed before cutting.

[0003] For example, a rubber gasket cutting device disclosed in the utility model with authorization announcement number CN219445216U sets a limit mechanism, passes the rubber tube through the herringbone plate and places it on the bottom plate, controls the telescopic cylinder to drive the telescopic rod to move downward, thereby driving the herringbone plate to move downward, and the herringbone plate presses the rubber tube to fix the rubber tube. By setting a driving mechanism, the driving mechanism drives the cutting mechanism to move up and down to cut the rubber tube continuously.

[0004] This prior art also has the following problems when used:

[0026] like Figure 1-Figure 4 As shown, a clamping assembly is arranged on the outside of the rubber tube 3, and the clamping assembly consists of a moving plate 7, an arc-shaped pressure plate 8, a U-shaped lifting plate 9, an inclined plate 10, a first spring 11, a guide rod 12, a second spring 17, a cross-shaped slider 20, a cross-shaped slide 21 and a transverse groove 23. Symmetrical arc-shaped pressure plates 8 are arranged on the front and rear sides of the rubber tube 3. The moving plate 7 is fixedly connected to the outside of the arc-shaped pressure plate 8. A cross-shaped slider 20 is fixedly arranged on the bottom surface of the moving plate 7. An inclined plate 10 is fixedly arranged on the bottom surface of the cross-shaped slider 20. A second spring 17 is fixedly arranged on the inside of the cross-shaped slider 20. A first spring 11 and a guide rod 12 are fixedly arranged on the top surface of the inner side of the U-shaped workbench 1. A U-shaped lifting plate 9 is fixedly arranged on the end of the first spring 11 away from the U-shaped workbench 1. The guide rod 12 penetrates the U-shaped lifting plate 9 and is slidably connected to the U-shaped lifting plate 9. The guide rod 12 can guide the movement of the U-shaped lifting plate 9. The top surface of the U-shaped workbench 1 is provided with symmetrical cross-shaped sliders. The U-shaped lifting plate 9 is moved downward, and the second spring 17 pushes the cross-shaped slider 20 to move outward at the same time. The cross-shaped slider 20 moves to drive the moving plate 7, the arc pressure plate 8 and the inclined plate 10 to move outward until the arc pressure plate 8 is separated from the rubber tube 3 to release the limit of the rubber tube 3.

[0027] like Figure 1-Figure 4As shown, a driving assembly is arranged outside the rubber tube 3, and the driving assembly consists of a threaded rod 13, a cam 14, a push plate 15, a servo motor 18, a threaded plate 19 and a vertical slot 22. A servo motor 18 is fixedly installed on the inner side of the U-shaped workbench 1, and a threaded rod 13 is fixedly arranged at the output end of the servo motor 18. The end of the threaded rod 13 away from the servo motor 18 is rotatably connected to the U-shaped workbench 1, and a cam 14 is fixedly arranged on the outer side of the threaded rod 13. The cam 14 is arranged on the bottom surface of the U-shaped lifting plate 9, and a threaded plate 19 is threadedly connected on the outer side of the threaded rod 13. A push plate 15 is fixedly arranged on the top surface of the threaded plate 19.

Running the servo motor 18 drives the threaded rod 13 to rotate, which can drive the threaded plate 19 and the push plate 15 to move left and right, so that the push plate 15 moves on the top surface of the U-shaped workbench 1. The periodic rotation of the threaded rod 13 can make the push plate 15 push the rubber tube 3 to move intermittently on the top surface of the U-shaped workbench 1, thereby realizing automatic feeding of the rubber tube 3. The rotation of the threaded rod 13 can also drive the cam 14 to rotate. The rotation of the cam 14 drives the U-shaped lifting plate 9 to move upward or downward, thereby driving the arc-shaped pressure plates 8 to move away from or close to each other, which is convenient for releasing the limit of the clamping assembly on the rubber tube 3.

[0028] Specific working principle:

[0029] When the device is used, the rubber tube 3 and the PVC film 16 are placed on the top surface of the U-shaped workbench 1 and close to the push plate 15, and the servo motor 18 is operated to drive the threaded rod 13 to rotate, and the rotation of the threaded rod 13 drives the threaded plate 19 and the push plate 15 to move in the direction close to the cutting knife 6, so that the push plate 15 pushes the rubber tube 3 and the PVC film 16 on the top surface of the U-shaped workbench 1 to move in the direction close to the cutting knife 6, and the rotation of the threaded rod 13 drives the cam 14 to rotate, and the rotation of the cam 14 drives the U-shaped lifting plate 9 to move upward, and the U-shaped lifting plate 9 moves upward. The movement of the lowering plate 9 drives the inclined plate 10 to move inward at the same time, the first spring 11 is compressed, the movement of the inclined plate 10 drives the moving plate 7, the arc-shaped pressure plate 8 and the cross-shaped slider 20 to move inward, and the second spring 17 is compressed until the rubber tube 3 to be cut moves to the bottom of the cutting knife 6. At this time, the U-shaped lifting plate 9 just moves to the highest position, and the inner side of the arc-shaped pressure plate 8 just touches the rubber tube 3, clamping the rubber tube 3, and the limiting effect is better. Turn off the servo motor 18 and run the driving machine 5 to drive the cutting knife 6 to rotate, and run the electric telescopic rod 4 drives the driving machine 5 and the cutting knife 6 to move downward, so that the rubber tube 3 can be cut into rubber rings, and the PVC soft film 16 is cut together with the rubber tube 3. After the cutting is completed, the electric telescopic rod 4 is operated to drive the driving machine 5 and the cutting knife 6 to move upward, and then the servo motor 18 is operated to drive the threaded rod 13 to continue to rotate. The rotation of the threaded rod 13 drives the cam 14 to rotate, and the rotation of the cam 14 drives the U-shaped lifting plate 9 to move downward. When the U-shaped lifting plate 9 moves downward, the second spring 17 pushes the cross-shaped sliding block 20 to move outward at the same time, and the cross-shaped sliding block 20 moves outward at the same time. The movement of block 20 drives the movable plate 7, the arc pressure plate 8 and the inclined plate 10 to move outward until the arc pressure plate 8 is separated from the rubber tube 3 to release the limit on the rubber tube 3. The threaded rod 13 rotates while driving the push plate 15 to continue to push the rubber tube 3 and the PVC film 16 to move until the rubber tube 3 to be cut moves to just below the cutting knife 6. Repeating the above operation can make the rubber tube 3 intermittently move on the top surface of the U-shaped workbench 1, and the cutting knife 6 periodically cuts the rubber tube 3, thereby realizing automatic feeding and cutting of the rubber tube 3, and the cutting efficiency is high.
