Description

Technical Field

[0001] The present application relates to the field of corrugated paper production, and particularly to a trimming device for corrugated paper production. Background Art

[0002] Corrugated cardboard is made into corrugated cartons through die-cutting, indentation, stapling or gluing. Corrugated cartons are the most widely used packaging products, and their usage has always been the first among various packaging products, including calcium plastic corrugated cartons. For more than half a century, corrugated cartons have gradually replaced transportation packaging containers such as wooden boxes with their superior performance and good processing performance, becoming the main force in transportation packaging. In addition to protecting goods, facilitating storage and transportation, they also play the role of beautifying and promoting goods.

[0003] Corrugated cartons are green environmental protection products. They are environmentally friendly and conducive to loading, unloading and transportation. During the processing of corrugated cartons, the two sides of the processed corrugated cardboard are usually not neat and need to be cut off to make the two sides flat. Usually, in the production process of corrugated cardboard, a cutting knife is used to cut the corrugated cardboard. The trimming device in the prior art cannot adjust the positions of the cutting knives on both sides according to the size of the corrugated paper, which affects the working efficiency of trimming and cannot effectively fix the corrugated paper.

Legs 2 are fixedly provided at both ends of the bottom surfaces of the two connecting plates 1. Roller transmission assemblies 3 are detachably provided at both ends between the two connecting plates 1. A trimming assembly is provided between the two groups of roller transmission assemblies 3. The trimming assembly includes a slide rod 13. Both ends of the slide rod 13 are rotatably connected to the two connecting plates 1 respectively. One end of the slide rod 13 penetrates through the connecting plate 1 and extends outward to be connected to the output end of a second motor 15. The second motor 15 is detachably connected to the connecting plate 1. Both ends of the slide rod 13 are sleeved with connecting rods 19 through bearings. The bearings are fixedly connected to the connecting rods 19 and are slidably connected to the slide rod 13. Circular cutters 14 are movably sleeved on the outer walls of the slide rod 13 on the opposite sides of the two connecting rods 19. Two chutes are symmetrically formed on the outer wall of the slide rod 13. The circular cutters 14 are slidably connected to the two chutes. Nuts 17 are sleeved on the outer walls of the slide rod 13 on the opposite sides of the two circular cutters 14. The nuts 17 are threadedly connected to the slide rod 13. A bidirectional threaded rod 18 is penetrated through the free ends of the two connecting rods 19. Side plates 12 are provided at both ends of the bidirectional threaded rod 18. The bidirectional threaded rod 18 is threadedly connected to the connecting rods 19 and the two ends of the bidirectional threaded rod 18 are respectively rotatably connected to the two side plates 12. The two side plates 12 are respectively fixedly connected to the two connecting plates 1. One end of the bidirectional threaded rod 18 penetrates through the side plate 12 and extends outward to be connected to the output end of a third motor 16. The third motor 16 is detachably connected to the side plate 12. By driving the bidirectional threaded rod 18 to rotate through the output end of the third motor 16, the rotation of the bidirectional threaded rod 18 drives the two connecting rods 19 thereon to move relatively in the horizontal direction of the bidirectional threaded rod 18. The relative movement of the two connecting rods 19 drives the circular cutters 14 to move relatively in the horizontal direction of the chutes on the slide rod 13, and the position of the circular cutters 14 can be fixed by the cooperation of the nuts 17 and the connecting rods 19. By adjusting the distance between the two circular cutters 14 and driving the slide rod 13 and the two circular cutters 14 thereon to rotate through the output end of the second motor 15, trimming operations can be performed on corrugated paper of different sizes, greatly improving the practicability of the device.

[0020] Referring toFigure 1 At both ends of the top surface of the two connecting plates 1, guide rods 5 are fixedly provided. Between the two guide rods 5, a threaded rod 9 and a vertical rod are respectively provided. A cross plate 4 is provided between the threaded rod 9 and the vertical rod. The cross plate 4 is threadedly connected to the threaded rod 9, and the vertical rod is slidably connected to the cross plate 4. A rectangular frame 11 is fixedly provided on the bottom surface of the cross plate 4. The four corners of the rectangular frame 11 are respectively slidably connected to the four guide rods 5. A plurality of support rods 7 are fixedly provided inside the rectangular frame 11. A plurality of rollers 6 are movably sleeved on the outer wall of each support rod 7. On the top surface of the front and rear adjacent two guide rods 5, a fixed plate 10 is fixedly provided. The top end of the threaded rod 9 penetrates through the fixed plate 10 and extends upward to be connected to the output end of a first motor 8. The two ends of the threaded rod 9 are respectively rotatably connected to the fixed plate 10 and the connecting plate 1. By driving the threaded rod 9 to rotate through the output end of the first motor 8, the rotation of the threaded rod 9 drives the cross plate 4 to move downward in the vertical direction of the vertical rod. The downward movement of the cross plate 4 drives the rectangular frame 11 to move downward in the vertical direction of the guide rod 5. The downward movement of the rectangular frame 11 drives the support rod 7 and the rollers 6 thereon to move downward. Through the plurality of rollers 6, the corrugated paper conveyed on the roller conveyor assembly 3 can be assisted in conveying, preventing it from being displaced during the conveying process, thereby affecting the trimming accuracy of the corrugated paper.

[0021] The implementation principle of an embodiment of the present application is as follows: When in use, the output end of the third motor 16 drives the bidirectional threaded rod 18 to rotate. The rotation of the bidirectional threaded rod 18 drives the two connecting rods 19 thereon to move relatively in the horizontal direction of the bidirectional threaded rod 18. The relative movement of the two connecting rods 19 drives the circular cutter 14 to move relatively in the horizontal direction of the chute on the sliding rod 13. And the position of the circular cutter 14 can be fixed by the cooperation of the nut 17 and the connecting rod 19. By adjusting the distance between the two circular cutters 14, and driving the sliding rod 13 and the two circular cutters 14 thereon to rotate through the output end of the second motor 15, the trimming operation of corrugated paper of different sizes can be carried out. And by driving the threaded rod 9 to rotate through the output end of the first motor 8, the rotation of the threaded rod 9 drives the cross plate 4 to move downward in the vertical direction of the vertical rod. The downward movement of the cross plate 4 drives the rectangular frame 11 to move downward in the vertical direction of the guide rod 5. The downward movement of the rectangular frame 11 drives the support rod 7 and the rollers 6 thereon to move downward. Through the plurality of rollers 6, the corrugated paper conveyed on the roller conveyor assembly 3 can be assisted in conveying, preventing it from being displaced during the conveying process, thereby affecting the trimming accuracy of the corrugated paper.
