Description

Technical Field

[0001] This utility model relates to the field of rubber cutting technology, specifically to an automatic cutting device for rubber seals. Background Technology

[0002] Rubber seals are components that utilize the high elasticity, media resistance, and weather resistance of rubber materials to fill sealing gaps through compression and deformation, thereby preventing fluid or gas leakage. They are widely used in the automotive, machinery, chemical, and aerospace industries, and are crucial components for ensuring normal equipment operation and extending service life. The manufacturing process of rubber seals mainly includes raw material preparation, cutting, mixing, vulcanization, processing and molding, and inspection and packaging. Among these, the cutting process is a delicate multi-step process designed to ensure the seal reaches the required size and shape to meet the sealing requirements of different applications.

[0003] Utility model application CN202222651648.8 relates to the field of rubber seal technology, specifically to a rubber seal cutting device, including a cutting frame, a first cross brace, and a second cross brace. A first hydraulic cylinder is fixed to the upper end of the first cross brace, and a cutting rod is fixed to the lower end of the telescopic rod of the first hydraulic cylinder. A first optical shaft is fixed to both ends of the cutting rod, and a cutting blade is fixed to the lower end of the first optical shaft. An installation rod is fixed above the cutting blade, and a dual-output shaft motor is fixed to the lower end of the installation rod. A cooling conveying roller is provided outside the dual-output shaft motor, and a cover plate is fixed above the cooling conveying roller. A fan is provided on one side of the cutting frame, and an air supply pipe is connected to the fan. An exhaust horizontal pipe is connected to the air supply pipe, and several exhaust vertical pipes are connected to the exhaust horizontal pipe. This utility model solves the problems of easy loosening, collapse, and adhesion of the rubber seal material at the cut surface by setting a cooling conveying roller that can push the rubber seal material and an exhaust vertical pipe that can blow cooling air to the cut surface.

[0004] The application proposes to reduce the adhesion of the rubber tube during cutting by delivering cold air. However, delivering cold air is not very effective and wastes resources. When blowing air onto the surface, it can also cause the rubber tube to deviate slightly during the cutting process, resulting in poor cutting effect.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide an automatic cutting device for rubber seals that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted:

[0008] An automatic cutting device for rubber seals includes: a spraying assembly for spraying rubber tubes, a cutting assembly for slitting rubber tubes, and an inner clamping assembly for clamping the inner wall of the rubber tubes.

[0009] The inner clamping assembly includes an installation tube, a first fixed ring, a second fixed ring, a movable ring, a threaded rod, a rotating ring, and a support plate. The installation tube is fixedly connected to one end of the first fixed ring, the second fixed ring is fixedly connected to the other end of the installation tube, the installation tube is fixedly connected to the threaded rod, the threaded rod is threadedly connected to the movable ring, and the threaded rod is rotatably connected to the rotating ring. Each of the first fixed ring, the second fixed ring, and the movable ring is provided with a connecting rod. One end of the connecting rod is rotatably connected to the first fixed ring, the second fixed ring, and the rotating ring, respectively, and the other end of the connecting rod is rotatably connected to the support plate.

[0010] The components inside the inner frame assembly are arranged in an array of four groups along the center of the mounting tube.

[0011] Furthermore, the cutting assembly consists of a sliding table, a mounting plate, and a cutting head; the sliding table is fixedly connected to the mounting plate, and the mounting plate is slidably connected to the sliding table.

[0012] Furthermore, the spraying assembly includes a first cylinder and a spray head; the output end of the first cylinder is fixedly connected to the spray head.

[0013] Furthermore, a control console is installed next to the spray head.

[0014] Furthermore, the support plate is T-shaped, and the top plate is arc-shaped.

[0015] Furthermore, a collection box is provided on one side of the cutting head.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides an automatic cutting device for rubber seals. By using a motor or manually rotating a rotating ring, the rotating ring drives a moving ring to move along the threaded direction on the threaded rod during rotation. As the moving ring moves along the threaded rod, its position gets closer and closer to the second fixed ring until it contacts the second fixed ring. During the movement of the moving ring, the connecting rod moves along the rotating connection with the support plate, causing the arc plate of the support plate to gradually approach the inner wall of the rubber tube, thus supporting the inner wall of the rubber tube. This facilitates the support of the inner wall of rubber tubes of different diameters, allowing the soft rubber tube to be supported into a round tube, which is convenient for subsequent cutting and shaping.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0025] like Figures 1 to 4 As shown, an automatic cutting device for rubber seals includes: a spraying assembly 1 for spraying rubber tubes, a cutting assembly 3 for slitting rubber tubes, and an inner clamping assembly 4 for clamping the inner wall of the rubber tubes.

[0026] The rubber hose is sprayed by the spraying assembly 1, which includes a first cylinder 11 and a spray head 12. The output end of the first cylinder 11 is fixedly connected to the spray head 12. The rubber hose is sprayed by the spray head 12 to cover its surface with a layer of lubricant, making the cutting of the rubber hose smoother.

[0027] The inner wall of the rubber tube is clamped by an inner clamping assembly 4, which includes an installation tube 41, a first fixing ring 42, a second fixing ring 43, a moving ring 44, a threaded rod 45, a rotating ring 46, and a support plate 47. The installation tube 41 is fixedly connected to one end of the first fixing ring 42, and the second fixing ring 43 is fixedly connected to the other end of the installation tube 41. The installation tube 41 is fixedly connected to the threaded rod 45, which is threadedly connected to the moving ring 44 and rotatably connected to the rotating ring 46. Each of the first fixing ring 42, the second fixing ring 43, and the moving ring 44 has a connecting rod. One end of each connecting rod is rotatably connected to the first fixing ring 42, the second fixing ring 43, and the rotating ring 46, respectively, and the other end is rotatably connected to the support plate 47. The internal components of the inner frame assembly are divided into... Four sets of support plates 47 are arranged in an array along the center of the mounting tube 41. The support plate 47 is T-shaped and the top plate is arc-shaped. By using a motor or manually rotating the rotating ring 46, the rotating ring 46 drives the moving ring 44 to move along the threaded direction of the threaded rod 45. While the moving ring 44 moves on the threaded rod 45, the position of the moving ring 44 approaches the second fixed ring 43 until the moving ring 44 contacts the second fixed ring 43. At this point, the diameter range of the supported round tube is at its maximum. During the movement of the moving ring 44, the connecting rod moves along the rotating connection with the support plate 47, so that the arc plates of the four sets of support plates 47 simultaneously contact the inner wall of the rubber tube, supporting the inner wall of the rubber tube. This facilitates the support of the inner wall of rubber round tubes of different diameters, making the soft rubber tube into a round tube, which is convenient for subsequent cutting and shaping.

[0028] As a supplement: the rubber tube is stretched into a round tube by the inner clamping component 4. When the rotating ring 46 is rotated by the motor or manually, the support plate 47 that supports the rubber tube will also drive the rubber tube to rotate, which is beneficial to the rotation of the rubber tube and its overall spraying.

[0029] After the rubber tube is clamped, it is cut by the cutting assembly 3, which consists of a sliding table 31, a mounting plate 32, and a cutting head 33. The sliding table 31 is fixedly connected to the mounting plate 32, and the mounting plate 32 is slidably connected to the sliding table 31. By placing the cutting head 33 at the bottom of the rubber tube, the rotation of the inner clamping assembly 4 causes the rubber tube to rotate, so that the surface of the rubber tube contacts the cutting head 33 and rotates automatically, allowing the rubber tube to be completely cut off. This facilitates the overall spraying of the rubber tube while rotating and cutting it. The position of the cutting head 33 can be moved by a cylinder or other power source, allowing the rubber tube to be cut into multiple groups. The rubber seals after cutting can be collected by the collection box next to the cutting head 33 for easy removal as a whole.

[0030] As a supplement, the support plate 47 is made of steel plate. When the cutting head 33 cuts the rubber tube, it will not damage the support plate 47 while the cutting head 33 is in contact with the cutting rubber tube. The sharpness of the cutting head 33 is not enough to cut the steel plate. At the same time, the support of the rubber tube by the four sets of support plates 47 helps to make the rubber tube round, so that it is round after cutting, which is convenient for subsequent vulcanization molding.

[0031] Working principle:

[0032] The rubber tube is sprayed with a layer of lubricant through the spray head 12, making the cutting process smoother. After spraying, the rotating ring 46 is rotated by a motor or manually, causing the moving ring 44 to move along the threaded direction of the threaded rod 45. As the moving ring 44 moves along the threaded rod 45, it gets closer to the second fixed ring 43 until it contacts the second fixed ring 43. During the movement of the moving ring 44, the connecting rod rotates along the joint with the support plate 47, causing the four sets of support plates 47 to simultaneously adhere to the inner wall of the rubber tube, supporting the inner wall of the rubber tube. This facilitates the support of the inner wall of rubber tubes of different diameters, allowing the soft rubber tube to be supported into a round tube, which is convenient for subsequent cutting and shaping.
