Description

Technical Field

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

[0002] A rubber seal ring cutter is a machine used to cut rubber seal rings. It can cut rubber cylinders into seal rings of specified sizes according to different requirements.

[0003] A search revealed a patent, CN219466227U, which discloses a cutting machine for producing O-ring rubber seals. The machine includes a movable base plate, a moving device inside the cutting chamber, a sliding assembly inside the moving device, and a cutting assembly inside the rotating disc. A push plate and a fixed seat are respectively installed on the top of the sliding plate. A second motor is installed on the inner side of the mounting plate, and a bidirectional screw is connected to the power drive end of the second motor. Moving seats are connected to both ends of the bidirectional screw. Fixed plates are installed on the upper surfaces of both moving seats, and several sets of compression springs are installed on the inner side of the fixed plates. A clamping arc plate is installed at one end of each compression spring. This device has an automatic clamping and fixing function and is suitable for rubber seals of different sizes, preventing the rubber seals from rotating or falling off the outside of the guide tube during cutting. By setting the cutting assembly, rubber seals can be cut to different sizes.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative document describes a method where a rubber tube is completely fitted onto the side of a conduit, and a cutting device is driven by a motor to rotate along the axis of the conduit, cutting the rubber tube into several sealing rings. However, in reality, there are many types of rubber sealing rings, and their circular sealing rings vary in size. In the aforementioned comparative document, because the conduit cannot be replaced and the position of the cutting device cannot be adjusted, it can only be used to cut a certain type of rubber tube, reducing the applicability of the cutting device. Therefore, there is an urgent need in the art to improve the rubber sealing ring cutting machine to overcome the shortcomings of the prior art. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-8A rubber sealing ring cutting machine includes a support platform 1 and a fixed frame 2 in an inverted U-shape fixedly mounted on the support platform 1. A rotating connecting shaft 3 is rotatably connected to one side of the fixed frame 2, passing through the side of the fixed frame 2. A rubber sleeve shaft 4 is provided at one end of the rotating connecting shaft 3 inside the fixed frame 2. A mounting seat 8 with a limiting effect is fixedly installed at the end of the rotating connecting shaft 3 near the rubber sleeve shaft 4. A mounting groove 9 adapted to the mounting seat 8 is opened at the end of the rubber sleeve shaft 4 near the rotating connecting shaft 3. A threaded end of the rubber sleeve shaft 4 passes through the inner wall of the mounting groove 9. The connecting locking bolt 10; a rotary drive unit 5 for driving the rotary connecting shaft 3 to rotate is provided on one side of the fixed frame 2; a cutting unit 6 for cutting and capable of moving up and down is provided at the top inside the fixed frame 2; a horizontal drive unit 7 for driving the cutting unit 6 to move along the length direction of the rubber sleeve shaft 4 is provided on one side of the fixed frame 2; a clamping unit adapted to the rubber sleeve shaft 4 and providing a clamping effect is provided on one end of the rotary connecting shaft 3 located inside the fixed frame 2; and an auxiliary rotary unit for assisting the positioning and rotation of the rubber sleeve shaft 4 is provided on the side of the fixed frame 2 away from the rotary connecting shaft 3.

[0033] Specifically, when cutting rubber seals, a rubber sleeve shaft 4 with an inner diameter matching the rubber cylinder to be cut is installed at one end of the rotary connecting shaft 3. The mounting groove 9 at one end of the rubber sleeve shaft 4 is fitted onto the side of the mounting seat 8 at the end of the rotary connecting shaft 3. A locking bolt 10 is inserted through the rotary connecting shaft 3, with its end threaded into the inner wall of the mounting groove 9. The locking bolt 10 is then tightened. Due to the limiting effect of the fit between the mounting groove 9 and the mounting seat 8, the installation of the rubber sleeve shaft 4 is completed. This facilitates the cutting of rubber cylinders with different diameters, increases the cutting range of the rubber seal cutting equipment, and allows the rubber cylinder to be fitted onto the rubber... On the side of the sleeve shaft 4, one end of the rubber cylinder is pressed by the clamping unit to prevent displacement of the rubber cylinder. The rotation drive unit 5 is activated to rotate the rubber cylinder sleeve shaft 4, causing the rubber cylinder to rotate. The cutting unit 6 is activated, and the cutting unit 6 can move up and down to cut rubber cylinders of different sizes. Before cutting, the position of the cutting unit 6 moving up and down and the distance of the horizontal drive unit 7 moving intermittently are preset by the external main controller. The cutting unit 6 cuts the rubber cylinder, and the horizontal drive unit 7 moves the cutting unit 6 intermittently to cut the rubber cylinder into several rubber sealing rings, improving the cutting efficiency of the rubber sealing rings.

[0034] As a technical optimization of this utility model, the rotary drive unit 5 includes a first drive motor 11 fixedly installed on one side of the fixed frame 2. The output end of the first drive motor 11 is fixedly installed with a first gear 12 that is rotatably connected to the side of the fixed frame 2. The rotary connecting shaft 3 is fixedly installed with a second gear 13 that meshes with the first gear 12 on one side of the side outside the fixed frame 2.

[0035] Specifically, turning on the first drive motor 11 causes the output of the first drive motor 11 to drive the first gear 12 to rotate, the first gear 12 drives the second gear 13 to rotate, and the second gear 13 drives the rotary connecting shaft 3 to rotate, thus realizing the rotation of the rotary connecting shaft 3.

[0036] As a technical optimization of this utility model, the cutting unit 6 includes a first telescopic device 14 located in the upper part of the fixed frame 2 and having a telescopic effect. A mounting frame 15 is fixedly installed at the telescopic lower end of the first telescopic device 14. A cutting disc 16 for cutting is rotatably connected inside the mounting frame 15. A second drive motor 17 for driving the cutting disc 16 to rotate is fixedly installed on the side of the mounting frame 15.

[0037] Specifically, the first telescopic device 14 is activated, and the telescopic end of the first telescopic device 14 can drive the mounting frame 15 to move up and down. The second drive motor 17 is started, and the output end of the second drive motor 17 drives the cutting disc 16 to rotate, cutting the rubber cylinder and cutting rubber sealing rings of different thicknesses.

[0038] As a technical optimization of this utility model, the horizontal drive unit 7 includes a third drive motor 18 fixedly installed on one side of the fixed frame 2, a sliding block 19 fixedly installed on the upper end of the first telescopic device 14, a sliding groove 20 adapted to the sliding block 19 is opened in the inner top wall of the fixed frame 2, and a drive screw 21 with one end connected to the output end of the third drive motor 18 is rotatably connected in the sliding groove 20. The drive screw 21 passes through the sliding block 19 and is threadedly connected to it.

[0039] Specifically, the third drive motor 18 is turned on, and the output end of the third drive motor 18 drives the drive screw 21 to rotate. The drive screw 21 drives the sliding block 19 to move in the sliding groove 20. The sliding block 19 drives the first telescopic device 14 to move, thereby adjusting the cutting position of the cutting unit 6. By pre-setting the output parameters of the third drive motor 18, sealing rings of different widths can be cut.

[0040] As a technical optimization of this utility model, the clamping unit includes a connecting seat 22 that is fixedly installed on one side of the rotating connecting shaft 3 and is symmetrically mounted inside the fixed frame 2. A clamping block 23 adapted to one side of the rubber sleeve shaft 4 is slidably connected to one side of the connecting seat 22. A moving groove 24 adapted to one end of the clamping block 23 is opened on one side of the connecting seat 22. A spring 25 for squeezing the clamping block 23 is provided in the moving groove 24. An adjusting bolt 26 is threadedly connected to the end of the connecting seat 22 away from the rotating connecting shaft 3. A squeezing plate 27 for squeezing the spring 25 is rotatably connected to the end of the adjusting bolt 26 located in the moving groove 24. A limiting nut 28 for limiting the position is threadedly connected to the side of the adjusting bolt 26.

[0041] Specifically, one end of the clamping block 23 has a chamfer. When the rubber cylinder is sleeved on the side of the rubber cylinder sleeve shaft 4 and its end moves between the two clamping blocks 23, it is used to push the rubber cylinder in the direction of the rotating connecting shaft 3. The clamping block 23 makes room. Since the spring 25 always has a squeezing force on the clamping block 23, one end of the rubber cylinder is clamped between the rubber cylinder sleeve shaft 4 and the two clamping blocks 23, which facilitates the clamping and fixing of the rubber cylinder and prevents the rubber cylinder from shifting during rotation. When cutting the rubber cylinder, the cutting starts from the end away from the rotating connecting shaft 3. If the clamping force of the clamping block 23 is too large or too small, or if a rubber cylinder sleeve shaft 4 of a different size is replaced, the tension of the spring 25 is adjusted by rotating the adjusting bolt 26. When the adjusting bolt 26 rotates, it drives the extrusion plate 27 to move in the moving groove 24. Then, the locking limit nut 28 is tightened to limit and fix the position of the adjusting bolt 26, thereby improving the stability and applicability of the rubber sealing ring cutting device.

[0042] As a technical optimization of this utility model, the auxiliary rotating unit includes a second telescopic device 29 that is fixedly installed on the fixed frame 2 at the end away from the rotating connecting shaft 3 and has a telescopic effect. The telescopic end of the second telescopic device 29 passes through the fixed frame 2 and is rotatably connected to a rotating pin 30. A top groove 31 that is adapted to the rotating pin 30 is opened at the center point of the end of the rubber sleeve shaft 4 near the second telescopic device 29.

[0043] Specifically, after the rubber sleeve is installed on the side of the rubber sleeve shaft 4, the second telescopic device 29 is activated. The output end of the second telescopic device 29 drives the rotating ejector pin 30 to move. The end of the rotating ejector pin 30 is positioned at the top groove 31, which improves the stability of the rubber sleeve shaft 4 when it rotates.

[0044] As a technical optimization of this utility model, the mounting base 8 has an inverted trapezoidal cross section, the mounting groove 9 is adapted to the mounting base 8, and the mounting base 8 is a rectangle with one end larger than the other, which can tightly connect the rubber sleeve shaft 4 and the rotary connecting shaft 3, thereby improving the stability of the rubber sleeve shaft 4 after it is installed at one end of the rotary connecting shaft 3.
