[0034] The first displacement component, the second displacement component and the cutting component can be used to adapt to rubber plates of various lengths, thereby making the adaptability thereof wider.

[0035] Wherein, a pressing component is also provided on the cutting component;

[0036] The pressing assembly includes a support frame 15, a positioning plate 16, a movable groove 17, a spring 18, a movable connecting frame 19 and a roller 21. The support frame 15 is symmetrically arranged on both sides of the cutting assembly at the bottom of the first displacement assembly. The positioning plate 16 is movably inserted into the interior of the support frame 15. The movable groove 17 is opened in the interior of the positioning plate 16. The spring 18 array is arranged at the upper end of the movable groove 17. The movable connecting frame 19 is movably installed at the lower end of the movable groove 17 and movably abuts against the bottom of the spring 18. A movable support plate 20 is fixedly installed at the bottom of the movable connecting frame 19, and the roller 21 array is installed on the surface of the movable support plate 20.

[0037] When the cutting assembly is extended during operation, the support frames 15 on both sides are driven down, thereby lowering the height of the positioning plate 16, and then the rollers 21 on the surface of the movable support plate 20 are in contact with the rubber plate, reducing the amplitude of its shaking;

[0038] By setting up a pressing component, it is prevented from moving too much during cutting, which would affect the cutting accuracy. Due to the setting of the spring 18 and the roller 21, the pressing component can press against rubber plates of various thicknesses and facilitate their movement with the conveyor belt 2.

[0039] Among them, the cutting assembly includes an installation frame 11, a telescopic rod 12, a cutting blade 13 and a top lifting plate 14. The installation frame 11 is arranged at the bottom of the first moving block 7 and the second moving block 10, the telescopic rod 12 is arranged at the bottom of the installation frame 11, and the cutting blade 13 is movably installed on the inner side of the lower end of the telescopic rod 12. The middle top lifting plate 14 is arranged on the left side of the telescopic rod 12 and is fixedly installed at the bottom of the installation frame 11. The top lifting plates 14 on the left and right sides are on the left side of the lower end of the telescopic rod 12.

[0040] When working, the middle top lifting plate 14 lifts the rubber sheet, then starts the telescopic rod 12 on the mounting frame 11 to extend, and then the cutting blade 13 performs cutting work, while the top lifting plates 14 on the left and right sides extend along with the telescopic rod 12, so that the rubber sheet can be lifted and cut;

[0041] By setting the cutting component, the cutting work can be conveniently performed when the work is being performed.

[0042] The top lifting plate 14 is configured to be L-shaped, and a bevel is provided on the edge of the lower end of the top lifting plate 14 .

[0043] During operation, the top lifting plate 14 is set into an L shape, and the edge of the lower end of the top lifting plate 14 is provided with a bevel, so that the rubber plate can be lifted, thereby avoiding accidentally cutting the conveyor belt 2 during cutting, causing damage to the conveyor belt 2.

[0044] Among them, the first displacement assembly includes a fixed support plate 8, a bidirectional screw 9 and a second moving block 10. The fixed support plate 8 is fixedly installed in the middle of the support frame 3, the bidirectional screw 9 is movably installed on the fixed support plate 8, and the front end of the second moving block 10 is symmetrically installed on the surface of the bidirectional screw 9.

[0045] When working, the bidirectional screw 9 on the fixed support plate 8 is started to move the second moving block 10 toward the middle, so that the distance between the cutting components on both sides is equal to the length of the rubber plate;

[0046] By setting the first displacement component, the width of the cutting component can be easily adjusted.

[0047] Among them, the second displacement assembly includes a first displacement screw 4, a movable plate 5, a second displacement screw 6 and a first movable block 7.

[0048] When working, the first displacement screw 4 is started to adjust the position of the moving plate 5, and then the second displacement screw 6 on the moving plate 5 is started to adjust the positions of the cutting components on both sides through the first moving block 7;

[0049] By providing the second displacement component, the length and position of the cutting component can be conveniently adjusted.

[0050] The width of the conveyor belt 2 is greater than the width of the rubber sheet.

[0051] During operation, the width of the conveyor belt 2 is made greater than the width of the rubber sheet, so that the cutting range of the rubber sheet is kept within the working range of the cutting assembly.

[0052] The working principle and use process of this utility model:

[0053] When working, the rubber sheet is placed on the conveyor belt 2, and then the conveyor belt 2 is started to move it to the processing station;

[0054] Then, the bidirectional screw rod 9 on the fixed support plate 8 is started to move the second moving block 10 toward the middle, so that the distance between the cutting blades 13 on both sides of the cutting assembly is equal to the length of the rubber sheet. At the same time, the top lifting plate 14 lifts the rubber sheet, and then the telescopic rod 12 on the mounting frame 11 is started to avoid accidentally cutting the conveyor belt 2 during cutting, which may cause damage to the conveyor belt 2.

[0055] At the same time, when the telescopic rod 12 is extended, the support frames 15 on both sides will be driven down, so that the height of the positioning plate 16 will be lowered, and then the rollers 21 on the surface of the movable support plate 20 will contact with the rubber plate, so as to avoid large movement during cutting, which will affect the cutting accuracy. In addition, due to the arrangement of the spring 18 and the roller 21, the pressing assembly can press against rubber plates of various thicknesses and facilitate their movement with the conveyor belt 2.

[0056] When trimming the left and right sides, the moving plate 5 is first started to make the left cutting assembly drop to a suitable height, and then the left side of the rubber sheet is abutted and cut under the action of the left second displacement screw 6 and the first moving block 7. Then the right cutting assembly is started to drop to a suitable height, and then the right side of the rubber sheet is abutted and cut under the cooperation of the right second displacement screw 6 and the first moving block 7. By setting the first displacement screw 4, the cutting assemblies on the left and right sides are moved in position, so as to adapt to rubber sheets of various lengths, thereby making it more adaptable.
