Description

Technical Field

[0001] The present application belongs to the technical field of paper cup processing, and in particular relates to a paper cutter for paper cup base paper. Background Art

[0002] A common paper cup is composed of a fan-shaped cylinder and a circular base, which are then glued together. The inside of the finished paper cup is coated with a synthetic resin, and the outside of the cylinder is printed with various patterns or texts. Paper cups of this configuration come in a variety of sizes, such as ordinary paper cups used in vending machines, take-away paper cups for beverages in stores, etc. The cylinder of the paper cup is printed with a variety of patterns such as the company's logo or text design, which is used for publicity or promotion, and is also used in advertising.

[0003] The existing foreign patent with publication number KR1020170047561A discloses a method for manufacturing paper cups, which can process printed patterns and concave-convex patterns on paper cup base paper. However, the base paper is prone to displacement during movement, resulting in displacement of the printed patterns and concave-convex patterns on the cut paper pieces, resulting in lower product quality. Summary of the invention

[0004] The purpose of this application is to provide a paper cutter for paper cup base paper in order to solve the above-mentioned technical problems, which can ensure that the paper cup base paper has high precision when cutting and ensure the position accuracy of the printed patterns and concave and convex patterns on the cut paper pieces.

[0005] The present application provides a paper cutter for paper cup base paper, comprising:

[0006] Original paper roll;

[0007] A printing device, used for printing a pattern on the base paper, the printing device comprising two printing rollers corresponding to each other;

[0008] A concave-convex forming device, used for forming concave-convex patterns on base paper, the concave-convex forming device comprising two forming rollers corresponding to each other;

[0009] A paper cutting device, used for cutting arc-shaped paper pieces from the base paper;

[0010] The anti-deflection mechanism is respectively installed on the printing device, the concave-convex forming device, and the paper cutting device;

[0011] Among them, the anti-deviation mechanism includes a punching column and a punching slot, which are respectively located at the two ends of two printing rollers, and the punching column and the punching slot correspond to each other. A first positioning column is provided at both ends of one of the forming rollers, and the paper cutting device is provided with a second positioning column.

[0012] The base paper is unrolled on the base paper roll. When passing through the printing device, a pattern is printed on the base paper by the printing roller. The base paper continues to move through the concave-convex forming device, and the concave-convex pattern is formed by the concave-convex forming device. Then, when the base paper moves to the paper cutting device, the paper cutting device cuts arc-shaped paper pieces for producing paper cups on the base paper. The base paper undergoes printing, concave-convex forming, and cutting processes successively. During the movement, the corresponding position on the base paper is easily deviated, resulting in low position accuracy. The anti-bias mechanism is used to improve the position of the printed pattern and the concave-convex pattern. The position accuracy on the cut paper pieces is improved by respectively arranging punching columns and punching slots on two printing rollers, so that small holes are processed on the side positions of the base paper when the base paper moves through the printing rollers. When the base paper moves through the forming rollers, the processing accuracy between the printed patterns and the concave and convex patterns on the base paper is improved by the first positioning columns on the forming rollers, and the position accuracy of the printed patterns and concave and convex patterns on the paper pieces cut from the base paper is improved by the second positioning columns. The first positioning columns and the second positioning columns correspond to the small holes processed on the base paper by the punching columns and the punching slots.

[0013] Furthermore, the second positioning column includes:

[0014] Conveyor belts;

[0015] A conveying wheel, on which the conveying belt is mounted;

[0016] Wherein, the second positioning column is installed on the conveyor belt, and the conveyor belt is installed on both sides of the paper cutting device.

[0017] The second positioning column is installed on the conveyor belt. When the second positioning column corresponds to the small hole, the movement of the base paper drives the conveyor belt to move. The conveyor belt is installed through the conveyor wheel to facilitate the movement of the conveyor belt.

[0018] Furthermore, the paper cutting device comprises:

[0019] The movable template is driven to move by a driving device;

[0020] The fixed template corresponds to the moving template;

[0021] Wherein, the conveyor belt and conveyor wheel are installed on the fixed template.

[0022] The paper pieces are cut from the base paper by the movable template and the fixed template. When the base paper moves between the movable template and the fixed template, the stability of the base paper during movement is ensured by the structure of the conveyor belt and the second positioning column.

[0023] Further, the movable template comprises:

[0024] Press seat, movably installed on the moving template;

[0025] A positioning hole is disposed on the pressure seat and corresponds to the second positioning column;

[0026] A return spring is placed between the pressure seat and the movable platen;

[0027] Wherein, a guiding cone surface is arranged at the end of the second positioning column.

[0028] The pressure seat is movably installed on the movable template. When the movable template on the paper cutting device moves for cutting, the pressure seat first presses the base paper around the second positioning hole to fix the base paper and place the base paper so that it will shift during cutting. The positioning hole corresponds to the second positioning column. When cutting the base paper, the second positioning column is inserted into the positioning hole. The guide cone surface ensures that the second positioning column can be stably inserted into the positioning hole.

[0029] Furthermore, the second positioning column is provided with a base.

[0030] The second positioning column is connected to the base, and the base is installed on the conveyor belt to improve the convenience of disassembly and assembly of the second positioning column. When the movable template moves to cut the base paper, the base paper is first pressed between the pressure seat and the base.

[0031] Furthermore, the anti-deflection mechanism also includes:

[0032] An abutment seat, mounted on the base;

[0033] Telescopic seat, movably installed on the fixed template;

[0034] A first spring, one end of which abuts against the telescopic seat;

[0035] A pressure sensor abuts against the other end of the first spring;

[0036] Wherein, a corresponding inclined guide surface is arranged between the abutting seat and the telescopic seat.

[0037] When the second positioning column moves with the base paper, when it moves to correspond to the movable template and the fixed template, the abutment seat and the telescopic seat abut against each other, and through the inclined guide surface between the abutment seat and the telescopic seat, the abutment seat moves simultaneously with the second positioning seat, so that the telescopic position of the telescopic seat is different, and the position of the abutment seat is detected by the first spring and the pressure sensor, and the position accuracy between the position to be cut on the base paper and the fixed template and the movable template is determined through program calculation and analysis.

[0038] The beneficial effects of this application are:

[0039] 1. The base paper undergoes printing, embossing and cutting processes successively. During the movement, the corresponding position on the base paper is easily deviated, resulting in low position accuracy. The anti-deviation mechanism is used to improve the position accuracy of the printed pattern and embossed pattern on the cut paper.

[0040] 2. By respectively arranging punching columns and punching grooves on the two printing rollers, small holes are processed on the side of the base paper when the base paper moves through the printing roller. When the base paper moves through the forming roller, the processing accuracy between the printed pattern and the concave and convex pattern on the base paper is improved through the first positioning column on the forming roller.

[0041] 3. The second positioning column is used to improve the position accuracy of the printed pattern and the concave and convex pattern on the paper cut from the base paper. The first positioning column and the second positioning column correspond to the small holes processed by the punching column and the punching groove on the base paper.
