Description

Technical Field

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

[0002] Rubber seals are sealing elements widely used in various industrial and everyday equipment. They are primarily used to prevent leakage of fluids, liquids, gases, or solid particles, as well as to prevent external impurities such as dust and moisture from entering the equipment. The manufacturing process of rubber seals involves cutting rubber into strips of specific lengths, followed by specific processing.

[0003] The positions of the cutters in existing strip cutting machines are fixed, making it difficult to adjust the spacing between two adjacent cutters. This makes it difficult to flexibly adapt to the cutting needs of products of different specifications and to cut rubber strips of different lengths, thus limiting its use. Furthermore, the clamping device of traditional strip cutting machines is fixed and cannot adapt to rubber strips of different widths or thicknesses, causing the material to easily slip or deform during cutting, affecting the quality and effect of the strip cutting. Utility Model Content

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0026] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0027] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] Combined with appendix Figure 1 and Figure 2 As shown, a rubber sealing ring cutting machine includes a worktable 1. A support frame 2 is provided on the left and right sides of the worktable 1. Multiple equally spaced pressing strip assemblies are connected to the support frame 2. Each pressing strip assembly includes a pressing plate 3. A screw 4 is threaded onto the support frame 2, with one end of the screw 4 rotatably connected to the top surface of the pressing plate 3. There are seven pressing strip assemblies on one support frame 2. Limiting rods 14 are connected to the pressure plate 3 on both sides of the screw 4. The top of the limiting rods 14 penetrates the top surface of the support frame 2. The bottom surface of the pressure plate 3 has an arc-shaped pressing groove 15. The arc-shaped pressing groove 15 can better contact the rubber strip, avoiding localized stress concentration and making the force more even. Meanwhile, vacuum suction cups 16 are connected to the worktable 1 below the support frame 2.

[0029] When cutting the rubber strip, first, the two ends of the rubber strip are fixed and clamped. Then, the screw 4 is rotated to lower the pressure plate 3 and apply pressure to the rubber strip. At the same time, the vacuum suction cup 16 works with the pressure strip assembly to fix the rubber strip by vacuum adsorption, thereby fixing the position of the rubber strip and preventing the rubber strip from warping or moving during cutting. This achieves stable and uniform fixing of the rubber strip and improves the cutting accuracy and quality. The pressure plate 3 can only move vertically under the restriction of the limit rod 14.

[0030] Combined with appendix Figure 1 , Figures 4 to 6As shown, the workbench 1 is provided with a second upright 5, and a cylinder 6 is connected to the center of the second upright 5. The telescopic end of the cylinder 6 is connected to a lifting frame 7, and a crossbeam 8 is connected to the lifting frame 7. A sliding hole 9 is opened on the crossbeam 8, and multiple cutters 10 are slidably connected in the sliding hole 9. The number of cutters 10 is three or more. A U-shaped part 11 is provided on the top surface of the cutter 10. A bolt 12 is threaded on the U-shaped part 11. One end of the bolt 12 passes through the sliding hole 9 and extends to the other end of the U-shaped part 11, where a nut 13 is threaded. The distance between the front and rear upright plates of the U-shaped part 11 matches the width of the crossbeam 8. Rubber pads 21 are glued to both sides of the front and rear upright plates. The rubber pads 21 increase the friction and improve the stability of the cutter 10 connection, which can prevent the cutter 10 from loosening due to vibration during cutting. Moreover, the rubber pads 21 can absorb part of the impact force.

[0031] After the rubber strip is fixed, select an appropriate number of cutters 10 and adjust them to a suitable spacing according to the cutting requirements. Then, install the cutters 10 on the crossbeam 8, tighten the nuts 13 to fix the cutting position, and the cylinder 6 drives the lifting frame 7 to descend, so as to drive the cutters 10 to descend and cut the rubber strip.

[0032] Among them, the combination of appendix Figures 4 to 6 As shown, a magnet 17 is embedded in the bottom surface of the crossbeam 8, and a magnet 18 is embedded in the top surface of the cutter 10, which is magnetically attracted to the magnet 17. Through the magnetic force cooperation of the magnet 17 and the magnet 18, the firmness and stability of the connection between the cutter 10 and the crossbeam 8 can be improved, ensuring the stability of the cutting process.

[0033] Combined with appendix Figure 1 and Figure 3 As shown, the lifting frame 7 is symmetrically connected with limit rods 19, and the upright frame 5 is provided with a socket 20 that is adapted to the limit rods 19. The limit rods 19 are inserted into the socket 20 and play a guiding role, providing stable vertical support for the lifting frame 7 and preventing the lifting frame 7 from shaking when the cylinder 6 extends or retracts.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
