Description

Technical Field

[0001] This utility model relates to the field of paper cutting technology, specifically to a high-efficiency cutting device for coated paper. Background Technology

[0002] Laminated paper is a specially treated type of paper with a layer of plastic film covering its surface. The lamination process involves covering the paper surface with a 0.012–0.020 mm thick transparent plastic film, creating a paper-plastic composite product. This treatment makes the paper surface smoother and glossier, improves the gloss and durability of printed materials, extends their lifespan, and provides protection against moisture, water, stains, abrasion, folding, and chemical corrosion.

[0003] Because of the high rigidity of laminated paper, the cut area needs to be clamped during cutting to prevent the paper from curling or deforming and causing the coating to detach. Most existing cutting devices for laminated paper use a guillotine to cut each side one by one. This process requires multiple rotations, positioning and cutting of the paper, which is very troublesome and has low cutting efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a high-efficiency cutting device for coated paper, which can simultaneously clamp and limit the two sides of the paper and cut it, and clamp and fix it before cutting it, thereby preventing the coating from falling off and improving the cutting efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A high-efficiency cutting device for coated paper, comprising:

[0007] The machine base, sliding seat, and lifting plate are arranged in a U-shape. The sliding seat and lifting plate are slidably mounted on the machine base, and a spring is provided between the top of the sliding seat and the lifting plate.

[0014] As an improvement, it also includes magnetic blocks and fixing frames; magnetic blocks are fixedly connected to the lower clamp and the upper clamp respectively through the fixing frames, and the magnetic blocks are set to clamp the track and arranged on the inner side of the track. After the upper and lower magnetic blocks attract each other, the two clamped tracks come into contact with each other, and under the action of the magnetic blocks attracting each other, the upper clamp moves left and right with the corresponding lower clamp.

[0015] As an improvement, the lifting and pressing structure includes a limiting post, a lifting motor, a rack and a gear; the limiting post is fixed to the bottom of the lifting pressure plate and is slidably set in the limiting groove reserved on the sliding seat; the rack is fixed to the side wall of the machine base; the lifting motor is fixed to the lifting pressure plate and a gear that meshes with the rack is connected and fixed on the drive shaft.

[0031] Base 1, sliding seat 2, and lifting plate 3; as shown Figure 3 As shown, the base 1 is a U-shaped structure with the opening facing upwards. Slide rails are formed on the inner walls of its two side walls, and the lifting plate 3 is slidably mounted on the slide rails. The sliding seat 2 is slidably mounted inside the base 1 and is arranged between the lifting plate 3 and the base 1. A spring is provided between the sliding seat 2 and the lifting plate 3. A lifting and pressing structure is provided between the sliding seat 2 and the lifting plate 3. A clamping conveyor belt and a clamping cutting edge structure are provided between the base 1 and the sliding seat 2. A cutting gate structure and a finished product collection structure are provided on one side of the base 1, and a guide roller 19 is provided on the other side. Grooves are reserved on the base 1 and the sliding seat 2 respectively.

[0032] Lifting and extrusion structure such as Figure 3 As shown, it includes a limiting post 24, a lifting motor 22, a rack 20, and a gear 21. The limiting post 24 is fixed to the bottom of the lifting plate 3 and is slidably set in the limiting groove 23 reserved on the sliding seat 2. The rack 20 is fixed to the inner side wall of the base 1. The lifting motor 22 is fixed on the lifting plate 3, and the drive shaft is connected and fixed with a gear 21 that meshes with the rack 20. After the lifting motor 22 is started, the lifting plate 3 moves downward and squeezes the sliding seat 2 through the spring, so that the sliding seat 2 abuts against the base 1. After the lifting motor 22 rotates in the opposite direction, the lifting plate 3 moves upward and pulls the sliding seat 2 upward through the limiting post 24.

[0033] Clamping conveyor belts, such as Figure 3 , Figure 7As shown, the system includes a conveyor belt 4, support rollers 6, sliding blocks 18, and a conveyor motor 5. The sliding block 18 is slidably disposed in a pre-reserved groove on the sliding seat 2, and a spring is provided between it and the sliding seat 2. A pair of conveyor belts 4 are arranged in a mirror image, one on the machine base 1 and the other on the sliding block 18, and the two conveyor belts 4 are in contact with each other. Each of the two conveyor belts 4 is equipped with a conveyor motor 5 (the conveyor motors 5 rotate in opposite directions and have the same speed). The two sets of support rollers 6 are fixed on the machine base 1 and the sliding block 18 on both sides, and are arranged horizontally on the inner side of the corresponding conveyor belts 4, and are in contact with the belts on the clamping side of the conveyor belts 4. After the coated paper enters between the machine base 1 and the sliding seat 2, it is clamped by the two conveyor belts 4 and moves forward by clamping the conveyor belts.

The two lower clamps 7 are slidably mounted in two slots of the base 1 and threaded onto both ends of the bidirectional screw 15. The bottom slot of the sliding seat 2 corresponds to the slot of the base 1, and a sliding rod 17 is provided in the slot of the sliding seat 2. Lifting sliders 16 are formed at both ends of the sliding rod 17 and are slidably mounted on the sliding seat 2. The upper clamp 8 is slidably mounted on the corresponding sliding rod 17. The paper cutter 9 is a vertically arranged circular disc, and its rotating shaft is rotatably mounted on the lower clamp 7 and drives the cutting motor 10. The paper cutter 9 is connected with two pairs of clamping tracks 11 mirrored on the left and right sides. The clamping tracks 11 on the same side are attached together vertically. The lower clamping track 11 is set on the lower clamping seat 7, and the upper clamping track 11 is set on the upper clamping seat 8. The magnetic blocks 13 are set corresponding to the clamping tracks 11 and arranged inside the clamping tracks 11. They are respectively connected and fixed to the corresponding lower clamping seat 7 and upper clamping seat 8 through the fixing bracket 12. After the upper and lower magnetic blocks 13 attract each other, the two clamping tracks 11 abut against each other, and the upper clamping seat 8 moves with the lower clamping seat 7. After the bidirectional screw 15 rotates, the two clamping cutting structures move relative to each other or in opposite directions. The coated paper that moves forward is clamped by the clamping tracks 11 and cut by the paper cutter 9. The lower clamping seat 7 is also fixed with a guide plate 14, and the coated paper enters between the two clamping tracks 11 through the guide plate 14.

[0035] Cut-off switch structure as follows Figure 2As shown, the device includes a knife switch 29, a knife switch seat 30, a limiting plate 31, a limiting slider 32, and an electric actuator 33.

One end of the knife switch 29 is rotatably mounted on the knife switch seat 30, and the other end forms a knife switch groove 34. The limiting plate is fixed on the base 1 and is provided with a vertically arranged limiting groove 35. The limiting slider 32 is simultaneously slidably mounted in both the limiting groove 35 and the knife switch groove 34. One end of the electric actuator 33 is fixed on the base 1, and the other end is connected and fixed to the limiting slider 32. When the electric actuator 33 retracts, the knife switch 29 rotates downward and cuts the coated paper.

[0036] Finished product collection structure as follows Figure 1 As shown, it includes a waste paper box 25, a support block 26, and an adjusting plate 27. The top of the waste paper box 25 is open and is arranged on one side of the machine base 1.

The adjusting plates 27 are slidably arranged on the waste paper box 25, and a telescopic rod 28 is provided between the bottom and the top of the side wall of the support block 26.

[0037] In the specific implementation of this embodiment:

[0038] Start the bidirectional screw 15 motor to make the two clamping cutting edge structures move relative to each other or in opposite directions, thereby adjusting the distance between the two paper cutters 9 and adjusting the position of the adjusting plate 27 (the adjusting plate 27 is set to correspond to the clamping cutting edge structure, that is, the distance between the two adjusting plates 27 is slightly larger than the width of the laminated paper after cutting).

[0039] The coated paper ring is placed on one side of the machine base 1, with one end resting on the guide roller 19, and then placed between the machine base 1 and the sliding seat 2. The conveyor motor 5 is started, and the coated paper moves forward under the action of the clamping conveyor belt. When passing through the clamping and cutting structure, both sides are clamped and limited by the clamping belts 11 corresponding to the clamping and cutting structure, and are cut by the paper cutters 9 on both sides (the paper cutters 9 rotate in the same direction as the clamping belts 11 below). When a certain length extends out of the machine base 1, the conveyor motor 5 stops, and the lifting motor 22 starts, and the lifting plate 3 moves downward. The sliding seat 2 is pressed by a spring, causing it to press against the machine base 1 and clamp the coated paper. Then, the electric push rod 33 retracts, causing the gate 29 to rotate downwards and cut the coated paper. After cutting, the coated paper falls onto the support block 26, and the waste paper strips on both sides fall into the waste paper box 25. Afterwards, the lifting motor 22 rotates in the opposite direction, and the lifting plate 3 moves upwards, pulling the sliding seat 2 upwards through the limit post 24. The transmission motor 5 starts again and repeats the above arrangement to efficiently complete the cutting of the coated paper.

[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
