Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Please refer to Figures 1-5 , the present utility model provides a technical solution: A slitter for cardboard production includes two symmetrically arranged support plates 20. A workbench 40 is fixedly installed at the center between the bottoms of the opposite surfaces of the two support plates 20. A pressing plate 41 is slidably installed at the center between the opposite surfaces of the two support plates 20. The pressing plate 41 is located directly above the workbench 40. At both ends between the opposite surfaces of the two support plates 20, conveying rollers 30 are rotatably installed. The conveying rollers 30 are evenly distributed on both sides of the workbench 40. The top ends of the conveying rollers 30 are flush with the upper surface of the workbench 40 to ensure that the cardboard is translated onto the workbench 40. At the positions corresponding to the workbench 40 on the upper surfaces of the two support plates 20, first chutes 21 are opened. In both of the two first chutes 21, cylinders 50 are slidably installed. A tool holder 60 is fixedly installed between the opposite surfaces of the top ends of the two cylinders 50. A cutting knife 70 is clamped to the lower surface of the tool holder 60;

[0024] The surface of the workbench 40 is penetrated with uniformly distributed first cutting grooves 42, and the surface of the pressing plate 41 is penetrated with second cutting grooves 43 corresponding to the first cutting grooves 42, ensuring that the cutting knife 70 drops vertically and the cutting work proceeds smoothly.

[0025] Wherein, a first slider 51 matched with the first sliding groove 21 is arranged at the bottom of the air cylinder 50. The air cylinder 50 is slidably installed on the top of the support plate 20 through the cooperation of the first slider 51 and the first sliding groove 21. The air cylinder 50 slides on the support plate 20 through the cooperation of the first slider 51 and the first sliding groove 21. The air cylinder 50 drives the tool holder to reciprocate on the support plate 20, facilitating the cutting work.

[0026] Wherein, a first lead screw 22 is rotatably installed in one of the first sliding grooves 21. A first nut sleeve is sleeved on the first lead screw 22 in a threaded manner. A fixed connection is established between the first slider 51 and the first nut sleeve. A first servo motor 24 for driving the first lead screw 22 to rotate is arranged at the end of the first sliding groove 21. The output end of the first servo motor 24 is fixedly connected to the end of the first lead screw 22. By utilizing the cooperation of the first servo motor 24 and the first lead screw 22, the air cylinder 50 drives the tool holder to reciprocate on the support plate 20, facilitating the cutting work.

[0027] Wherein, second sliding grooves 25 are respectively opened at the four corners of the pressing plate 41 corresponding to the inner sides of the two support plates 20. Second sliders 23 matched with the second sliding grooves 25 are arranged at the four corners of the pressing plate 41. The pressing plate 41 is slidably installed between the two support plates 20 through the cooperation of the second sliders 23 and the second sliding grooves 25. By utilizing the up-and-down sliding of the pressing plate 41, the cardboard is clamped during cutting, and when the cutting is completed, the pressing plate 41 is separated from the cardboard, enabling the cardboard to move smoothly.

[0028] Wherein, a second lead screw 26 is rotatably installed in one of the second sliding grooves 25. A second nut sleeve is sleeved on the second lead screw 26 in a threaded manner. A fixed connection is established between the second slider 23 and the second nut sleeve. A second servo motor 27 for driving the second lead screw 26 to rotate is arranged at the position of one of the support plates 20 corresponding to the second sliding groove 25. The output end of the second servo motor 27 is fixedly connected to the end of the second lead screw 26. By utilizing the cooperation of the second servo motor 27 and the second lead screw 26, the up-and-down sliding of the pressing plate 41 is realized.

[0029] Wherein, the width dimensions of the first cutting grooves 42 and the second cutting grooves 43 are greater than the thickness dimension of the cutting knife 70. The cutting knife 70 does not contact the inner walls of the first cutting grooves 42 and the second cutting grooves 43, ensuring the smooth progress of the cutting work and simultaneously protecting the cutting knife 70 from being damaged. The farthest extension of the cutting knife 70 reaches the bottom end of the inner wall of the first cutting groove 42, enabling the cutting knife 70 to smoothly penetrate through the cardboard and ensuring that the cutting is in place.

[0030] Among them, the lower surface of the tool rest 60 is provided with clamping grooves 61 corresponding to the first cutting grooves 42 one by one. The top end of the cutting knife 70 is provided with a clamping block 71 that cooperates with the clamping groove 61. The end of the clamping block 71 is fixedly connected to the top end of the cutting knife 70. Since the cutting knife 70 can be clamped at different positions on the tool rest 60, the slitter can complete cutting work of different sizes in one slitting operation.

[0031] Among them, columns 10 are provided at both ends of the bottoms of the two support plates 20. Universal wheels 80 are provided on the columns 10, and brake parts are provided on the universal wheels 80, which facilitates the movement and fixation of the slitter.

[0032] Working principle: During use, conveyor rollers 30 are arranged on both sides of the workbench 40. The cardboard to be processed is placed on the conveyor rollers 30 in sequence. Push the cardboard at the tail to move the foremost cardboard to the workbench 40. Start the second servo motor 27, and the pressing plate 41 descends to the cardboard, sandwiching the cardboard between the workbench 40 and the pressing plate 41. Clamp the cutting knife 70 according to the size to be slit. Start the first servo motor 24 and the cylinder 50, move the cutting knife 70 to a suitable position for slitting. After slitting is completed, the cylinder 50 drives the cutting knife 70 and the pressing plate 41 to rise in sequence. Push the cardboard at the tail again to move the cut cardboard to the conveyor rollers 30 on the other side of the workbench 40. Since the cutting knife 70 can be clamped at different positions on the tool rest 60, the slitter can complete cutting work of different sizes in one slitting operation, improving the overall processing efficiency of the slitter.

[0033] Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
