[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a cutting device for processing rubber seals, including a machine base 1, an installation area 3 is provided through the top of the machine base 1, and a second roller 5 is rotatably installed in the installation area 3. A frame 2 is installed on the top of the machine base 1, and a continuous cutting component is provided on the frame 2.

[0025] The continuous cutting assembly includes a first roller 4, a cutter 9, and a cutting groove 10. The first roller 4 is rotatably mounted inside the frame 2, and multiple cutters 9 are mounted on the first roller 4. Multiple cutting grooves 10 are opened on the second roller 5. The cutter 9 and the cutting groove 10 cooperate to cut and shape the rubber seal.

[0026] Specifically, the first roller 4 is horizontally rotated and installed inside the frame 2, with its axis parallel to the axis of the second roller 5. The distance between them can be preset and adjusted according to the thickness of the rubber seal. The cutters 9 on the first roller 4 are evenly distributed along the circumference of the roller body, and the spacing between adjacent cutters 9 can be designed according to the size requirements of the seal. Correspondingly, the cutting grooves 10 on the second roller 5 are perfectly matched with the cutters 9 in terms of quantity, spacing, and position. When the raw material for the rubber seal is conveyed between the first roller 4 and the second roller 5, as the two rollers rotate synchronously in opposite directions, the cutters 9 can accurately embed into the cutting grooves 10, using the cooperation between the blade and the inner wall of the cutting groove to cut the raw material. Multiple seals can be cut in one rotation, realizing continuous production. Compared with the intermittent cutting of traditional single cutters, the efficiency is significantly improved.

[0027] Furthermore, each of the grooves 10 has a receiving groove 11 at the bottom, and each receiving groove 11 is equipped with a spring 13. Each spring 13 has a pop-out plate 15 installed at its end, and the pop-out plate 15 is slidably disposed in the groove 10.

[0028] Specifically, the top surface of the ejector plate 15 is flush with the outer circumference of the second roller 5, ensuring that the raw material will not be wrinkled due to the protrusion of the ejector plate 15 during conveying. When the cutter 9 cuts into the groove 10, it will first contact the ejector plate 15 and press it downward into the groove 10. At this time, the spring 13 is compressed in the receiving groove 11 and stores elastic potential energy. When the cutter 9 rotates away from the groove 10 with the first roller 4, the elastic potential energy of the spring 13 is released, pushing the ejector plate 15 to slide upward and reset, ejecting the rubber seal that may stick to the groove 10 after cutting to the surface of the second roller 5, and conveying it to the next process with the rotation of the roller body. This effectively avoids the problem of rubber jamming due to stickiness and reduces the frequency of manual cleaning.

[0029] Furthermore, multiple guide grooves 12 are provided at the bottom of the groove 10, and guide posts 14 are slidably inserted into each guide groove 12. The guide posts 14 are all installed on the outer wall of the pop-out plate 15.

[0030] Specifically, the guide groove 12 is formed along the depth direction of the cut groove 10 and is evenly distributed on the outer periphery of the receiving groove 11. The length of the guide post 14 is adapted to the depth of the guide groove 12, and its outer wall is tightly fitted with the inner wall of the guide groove 12. When the ejector plate 15 slides up and down under the action of the spring 13, the guide post 14 will slide synchronously along the guide groove 12, thereby limiting the movement trajectory of the ejector plate 15 and preventing it from tilting or deviating during the sliding process. This structure not only ensures that the ejector plate 15 ejects the seal with uniform force, but also reduces the frictional wear between the ejector plate 15 and the inner wall of the cut groove 10, extending the service life of the component.

[0031] Furthermore, a motor 6 is installed on the outer wall of the machine base 1, and the motor 6 is used to drive the second roller 5 installed in the installation area 3 to rotate;

[0032] Specifically, motor 6 is bolted to the outer wall of machine base 1, and its output shaft is connected to one end of the second roller 5 via a coupling, providing power for the rotation of the second roller 5. Motor 6 can be a servo motor or a geared motor. By controlling its speed, the rotation speed of the second roller 5 can be adjusted, thus adapting to the cutting needs of rubber raw materials of different thicknesses and hardnesses. When motor 6 starts, the output shaft drives the second roller 5 to rotate stably around its own axis within the installation area 3, providing continuous power support for continuous cutting operations.

[0033] Furthermore, a first gear 7 is installed at the end of the first roller 4 located outside the frame 2, and a second gear 8 is installed at the end of the second roller 5 located outside the machine base 1. The first gear 7 and the second gear 8 mesh with each other.

[0034] Specifically, the first gear 7 and the second gear 8 have the same module and number of teeth, ensuring that their linear speeds are consistent when they mesh and rotate. When the motor 6 drives the second roller 5 to rotate, the second gear 8 at the end of the second roller 5 rotates synchronously. Through meshing with the first gear 7, it drives the first roller 4 to rotate in the opposite direction at the same speed. This synchronous transmission method ensures that the cutter 9 and the cutting groove 10 always maintain precise alignment during rotation, avoiding collision between the cutter 9 and the surface of the second roller 5 or displacement of the cutting position due to asynchronous speeds, effectively improving the cutting accuracy of the rubber seal.

[0035] Furthermore, a conveyor belt 16 is horizontally installed on the top of the machine base 1, and the height of the conveyor belt 16 is the same as the height of the top of the second roller 5.

[0036] Specifically, the conveyor belt 16 is horizontally installed on the top of the machine base 1, with its conveying direction perpendicular to the axes of the first roller 4 and the second roller 5. One end of the conveyor belt 16 extends to the feed side of the first roller 4 and the second roller 5, and the other end can be connected to the raw material unwinding device. The height of the conveyor belt 16 is flush with the top of the second roller 5, ensuring that there is no height difference when the rubber raw material is conveyed from the conveyor belt 16 to the surface of the second roller 5, avoiding wrinkles or deformation of the raw material due to gravity. At the same time, the conveying speed of the conveyor belt 16 can be adjusted by an independent drive mechanism to match the rotation speed of the second roller 5, ensuring that the raw material can enter the cutting area continuously and smoothly, further improving the continuity and stability of the cutting operation.

[0037] The workflow of this embodiment is as follows: Motor 6 drives the second roller 5 to rotate. The second roller 5 drives the first roller 4 to rotate synchronously in the opposite direction through the meshing of the first gear 7 and the second gear 8. The raw material of the rubber seal to be cut is placed on the conveyor belt 16 and is smoothly transported by the conveyor belt 16 to the space between the first roller 4 and the second roller 5. The cutter 9 on the first roller 4 rotates with the roller body and cooperates with the corresponding cutting groove 10 on the second roller 5 to continuously cut the raw material. During the cutting process, the cutter 9 presses down on the ejector plate 15 to compress the spring 13. After the cutter 9 is released, the spring 13 pushes the ejector plate 15 to push out the seal to avoid jamming. The cut seal is installed below the installation area 3 as the second roller 5 rotates, realizing fully automated continuous cutting.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
