DETAILED DESCRIPTION

[0024] To make the purpose, technical scheme and advantages of the embodiment of the present application clearer, the technical scheme of the present application will be described clearly and completely below in combination with the embodiments.

[0025] EMBODIMENT

[0026] Figures 1-3 In the embodiment, the rubber plate equidistant cutting device comprises a vibrating knife cutting machine 10, the top of the vibrating knife cutting machine 10 is provided with a smoothing assembly 20, the smoothing assembly 20 comprises a following part 21, a moving plate 22 and two limiting tracks 23, the two ends of the moving plate 22 are movably inserted into the two limiting tracks 23, the moving plate 22 is provided with a plurality of first rolling wheels 24 inside the limiting tracks 23, in the technical scheme, the number of the first rolling wheels 24 at one end of the moving plate 22 is three, the machine head 11 of the vibrating knife cutting machine 10 drives the following part 21 to move so that the moving plate 22 moves reciprocatingly in the horizontal direction, the horizontal direction is parallel to the direction of the limiting track 23, and the vertical direction is perpendicular to the direction of the limiting track 23.

[0027] The central control center of the vibrating knife cutting machine 10 controls the movement of the machine head 11 so that the vibrating knife cuts the rubber plate equidistantly, the following part 21 moves with the machine head 11 and drives the moving plate 22 to move in the direction of the limiting track 23, the moving plate 22 supports the surface of the rubber plate at the cutting position, and the deformation of the rubber plate caused by the pushing of the vibrating knife is avoided, so that the size difference of the rubber pieces cut out is avoided.

[0028] The follower unit 21 includes a mounting frame 31, which is fixedly connected to the head 11 of the vibrating knife cutting machine 10. Telescopic frames 32 are movably inserted into both sides of the mounting frame 31. Multiple second rolling wheels 33 are provided at the bottom of the telescopic frame 32. In this technical solution, there are two second rolling wheels 33 at the end of the telescopic frame 32. The second rolling wheels 33 are rotatably inserted into the moving plate 22. Due to the different shapes of the required rubber sheets, the cutting path is not straight in the longitudinal and transverse directions. A certain section of the cut rubber sheet may be arc-shaped, or it may have a certain angle relative to the longitudinal or transverse direction. When the follower unit 21 moves with the head 11, it splits the direction of the head 11. The longitudinal direction moves along the direction of the moving plate 22, and the transverse direction pushes and drives the moving plate 22 to move, so that the cutting knife can cut the rubber sheet in any direction.

[0029] Before cutting the rubber sheet, the required size parameters of the rubber sheet are input into the control center of the vibrating knife cutting machine 10. Then, the rubber sheet is placed on the worktable of the vibrating knife cutting machine 10. The conveyor belt on the surface of the worktable transports the rubber sheet to the cutting position. Then, the vibrating knife cutting machine 10 is started through the control center. The machine head 11 drives the vibrating knife to cut the rubber sheet at equal intervals. The movement of the machine head 11 causes the follower 21 to move. When the follower 21 moves, the mounting frame 31 drives the two telescopic frames 32 to move. The first rolling wheel 24 at the bottom moves accordingly. The movement direction of the follower 21 is divided into two directions, horizontal and vertical, by the moving plate 22. The follower 21 only drives the moving plate 22 to move horizontally. When the follower 21 moves horizontally, the second rolling wheel 33 rotates accordingly to avoid friction between the telescopic frame 32 and the moving plate 22. During the movement, the moving plate 22 smooths the cut area and presses it to support it, so that the rubber sheet will not be pushed and deformed by the vibrating knife during cutting.

[0030] The follower unit 21 can move the moving plate 22 by moving the head 11. The moving plate 22 moves only laterally, adapting to the non-linear cutting of the vibrating knife driven by the head 11 to cut the rubber sheet in any shape. The moving plate 22 smooths and presses the rubber sheet and rubber patch at the cut, preventing the vibrating knife from pushing the rubber sheet during cutting and causing deformation of its surface, thereby avoiding errors in the size of the cut rubber patch.

[0031] The method of using this rubber sheet equidistant cutting device includes the following steps:

[0032] S1. Input the required size parameters of the rubber sheet into the control center of the vibrating knife cutting machine 10 and start it. The machine head 11 drives the vibrating knife to cut the rubber sheet.

[0033] S2. The movement of the machine head 11 causes the follower 21 to move. The follower 21 moves normally in the longitudinal direction, only driving the moving plate 22 to move in the lateral direction.

[0034] S3. During the movement of the moving plate 22, the cut area is smoothed and pressed for support, so that the rubber plate will not be pushed and deformed by the vibrating knife during cutting.

[0035] In the technical solution of the rubber sheet equidistant cutting device, the follower 21 drives the moving plate 22 to move with the machine head 11, adapting to the non-linear cutting of the vibrating knife driven by the machine head 11 to cut the rubber sheet in any shape. The vibrating knife is always in the middle position of the moving plate 22, and the hollow middle part will not block the longitudinal movement path of the vibrating knife, ensuring normal cutting of the rubber sheet. The moving plate 22 always presses and supports the surface of the rubber sheet to prevent the rubber sheet from being pushed and deformed during cutting.

[0036] Figures 4-5 In the middle, the bottom of the moving plate 22 is provided with two sets of rolling parts 40. The rolling part 40 includes multiple rollers 41. One end of one roller 41 is fixedly connected to the output end of an external forward and reverse motor. A set of transmission gears 42 is provided between the ends of two adjacent rollers 41, and the two transmission gears 42 in the same set are meshed and connected.

[0037] The roller 41 is inclined, and the angle between the central axis of the roller 41 and the moving plate 22 is between 5 and 12 degrees.

[0038] When the moving plate 22 moves laterally, the external forward and reverse motor works and drives the roller 41 to rotate. Under the transmission of the transmission gear 42, multiple rollers 41 rotate simultaneously. According to the moving direction of the machine head 11, the external forward and reverse motor drives the roller 41 to rotate in the forward or reverse direction. The roller 41 passes through the rubber plate cut at an inclined state to avoid squeezing the rubber plate cut.

[0039] The rolling part 40 can prevent friction between the moving plate 22 and the rubber plate. At the same time, the roller 41 can pass through the cutting point of the rubber plate at an incline, so as to prevent the roller 41 from squeezing the cutting point of the rubber plate and causing deformation of the rubber plate, which would affect the cutting work of the vibrating knife.

[0040] Figures 1-2 In the middle, the bottom of the limiting track 23 is fixedly connected to the worktable of the vibrating knife cutting machine 10 by bolts, and the height between the limiting track 23 and the worktable of the vibrating knife cutting machine 10 is adjusted by adjusting the fixing position of the bolts.

[0041] When cutting rubber sheets of different thicknesses, the distance between the limiting rail 23 and the worktable of the vibrating knife cutting machine 10 is adjusted by adjusting the fixed position of the limiting rail 23 with the adjusting bolt. After the height of the limiting rail 23 is adjusted, the height of the moving plate 22 will change accordingly, and the distance between the moving plate 22 and the worktable of the vibrating knife cutting machine 10 will change, ensuring that the bottom of the roller 41 is in contact with the surface of the rubber sheet, and ensuring that the device can be used for rubber sheets of different thicknesses.

[0042] Working principle of the rubber sheet equidistant cutting device:

[0043] Before cutting the rubber sheet, the required size parameters of the rubber sheet are input into the control center of the vibrating knife cutting machine 10. The rubber sheet is then placed on the worktable of the vibrating knife cutting machine 10. The conveyor belt on the worktable transports the rubber sheet to the cutting position. The height of the two limit rails 23 is adjusted by adjusting the fixing position of the limit rails 23 with the adjusting bolts to ensure that the roller 41 at the bottom of the moving plate 22 is in contact with the surface of the rubber sheet. The vibrating knife cutting machine 10 is then started via the control center. The machine head 11 drives the vibrating knife to cut the rubber sheet at equal intervals. The movement of the machine head 11 causes the follower part 21 to move. When the follower part 21 moves, the mounting frame 31 drives the two telescopic frames 32 to move, and the first rolling wheel 24 at the bottom moves accordingly. The direction of movement of the follower part 21 is changed. The moving plate 22 is disassembled into two directions of movement: horizontal and vertical. The follower part 21 only drives the moving plate 22 to move horizontally. When the follower part 21 moves horizontally, the second rolling wheel 33 rotates accordingly to avoid friction between the telescopic frame 32 and the moving plate 22. During the movement of the moving plate 22, the cutting area is smoothed and pressed and supported, so the rubber plate will not be pushed and deformed by the vibrating knife. When the moving plate 22 moves horizontally, the external forward and reverse motor works and drives the roller 41 to rotate. According to the moving direction of the machine head 11, the external forward and reverse motor drives the roller 41 to rotate in the forward or reverse direction. Under the transmission of the transmission gear 42, multiple rollers 41 rotate simultaneously. The rollers 41 pass through the rubber plate cutting area in an inclined state to avoid squeezing the rubber plate cutting area.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
