Description

Technical Field

[0001] The utility model belongs to the technical field of paper embossing equipment, and in particular relates to an embossing structure which is not easy to peel off paper. Background Art

[0002] In the production process of paper products, such as paper towels, in order to achieve a better decorative effect, many paper towels have embossed patterns on their surfaces to meet different market demands.

[0003] Paper is usually made of multiple layers of paper stacked together, and the paper is embossed by an embossing device. In order to prevent the paper from peeling off, existing paper towels usually use a spray method to spray adhesive between the papers to improve the anti-peeling property of the paper. However, the paper after spraying the adhesive is prone to lose its proper softness and smoothness, which is not conducive to the consumer's use experience. Utility Model Content

[0004] The purpose of the utility model is to provide an embossing structure that is not easy to peel off the paper in order to solve the above-mentioned technical problems, so as to achieve the effect of tightly combining the paper layers by physical means while maintaining the overall quality of the paper.

[0005] In view of this, the utility model provides an embossing structure that is not easy to peel off paper, characterized by comprising:

[0006] A base, wherein the base is arranged in a U shape, and a flat roller and an embossing roller are rotatably arranged in a groove of the base, and the embossing roller is movably arranged above the flat roller;

[0007] A lifting structure, which is arranged between the embossing roller and the base and is used to adjust the height of the embossing roller;

[0008] The convex blocks are arranged on the outer wall of the embossing roller, and a plurality of the convex blocks are evenly distributed in the circumferential direction of the embossing roller.

[0009] In this technical solution, when multiple layers of paper pass between the flat roller and the embossing roller with bumps, the bumps on the embossing roller exert pressure on the paper to form an embossing effect, so that the layers of paper are physically interlocked, thereby enhancing the bonding force between the layers and achieving the purpose of not being easy to peel off. Since this process does not involve the use of chemical adhesives, the softness and smoothness of the paper can be maintained, and it is also more environmentally friendly.

[0010] In the above technical solution, further, the contact surface between the top of the protrusion and the paper is set to be a hemispherical surface.

[0011] In the present technical solution, the hemispherical surface provided during the embossing process helps to disperse the pressure and reduce local stress concentration, thereby preventing the paper from being damaged or excessively thinned. The hemispherical protrusions are also easier to demold from the paper, preventing the paper from adhering to the embossing roller, thereby ensuring the continuity and stability of the production process.

[0012] In the above technical solution, further, an inclined surface is circumferentially arranged between the hemispherical surface arranged on the top of the protrusion and the outer wall of the protrusion.

[0013] In the present technical solution, the transition from the outer wall of the protrusion to the hemispherical top is smoother by setting the inclined surface, which helps the paper to enter and exit the embossing area more smoothly during the embossing process and reduces the tearing or damage of the paper during the embossing process.

[0014] In the above technical solution, further, a cleaning structure is provided above the embossing roller.

[0015] In the above technical solution, further, the cleaning structure includes:

[0016] A mounting seat, wherein the mounting seat is symmetrically arranged on the lifting structure and can simultaneously drive the embossing roller and the cleaning structure to move when the lifting structure moves;

[0017] A collecting hood, which is arranged below the mounting seat and connected to the bottom surface of the mounting seat;

[0018] A cleaning roller, which is arranged in a transverse rotation in the collecting cover and contacts with the outer wall of the embossing roller;

[0019] A driving motor, wherein the driving motor is arranged on a mounting seat, and an output shaft passes through the mounting seat and a first bevel gear is arranged at the end thereof;

[0020] A second bevel gear, the second bevel gear is arranged on the side of the first bevel gear and meshes with the first bevel gear;

[0021] The adsorption structure is symmetrically arranged on both sides of the cleaning roller to adsorb the foreign matter being cleaned;

[0022] Wherein, the central axis of the second bevel gear is connected to the central axis of the cleaning roller.

[0023] In this technical solution, the cleaning roller can be driven to rotate by the cooperation between the driving motor, the first bevel gear, and the second bevel gear to clean the surface of the embossing roller. During the cleaning process, the symmetrically arranged adsorption structure can collect the foreign matter after cleaning, preventing the foreign matter from falling onto the paper or floating in the working environment, thereby improving environmental hygiene and paper quality. The cleaning structure ensures the cleanliness of the embossing roller during the working process, maintains the stability of the embossing effect and the consistency of paper quality, and also reduces the frequency and difficulty of equipment maintenance.

[0024] In the above technical solution, further, the adsorption structure includes:

[0025] Adsorption tubes, which are symmetrically arranged on both sides of the cleaning roller, and each of the adsorption tubes is provided with a feed port on the side wall close to the cleaning roller;

[0026] A filter structure, wherein the filter structure is arranged on the side of the base, and a connecting pipe is arranged between the top of the filter structure and the adsorption tube;

[0027] The vacuum pump is arranged inside the filtering structure to drive the adsorption tube to adsorb foreign matter.

[0028] In this technical solution, through the cooperation between the vacuum pump, the connecting pipe, the adsorption pipe, and the feed port, the foreign matter cleaned by the cleaning roller can be adsorbed and transported to the filtering structure, and the foreign matter can be filtered and collected to prevent the foreign matter from directly floating in the production environment and affecting the quality of paper production. The adsorption structure is conducive to keeping the production environment clean, reducing the maintenance requirements of the equipment, and improving the overall production efficiency.

[0029] In the above technical solution, further, the filtering structure includes:

[0030] A filter box, wherein the top of the filter box is connected to the connecting pipe;

[0031] A slot, wherein the slot is symmetrically arranged on the inner wall of the filter box;

[0032] A collection frame, wherein ear plates are fixedly arranged on both sides of the collection frame, and the ear plates are slidably connected to the slots;

[0033] A filter plate, which is arranged at the bottom of the collection frame and is used to filter foreign matter in the air;

[0034] An air outlet, the air outlet is opened below the collection frame and located on the outer wall of the filter box;

[0035] A handle, which is fixedly arranged on the front of the collecting frame and is used to pull the collecting frame out of the filter box;

[0036] Wherein, the air inlet side of the vacuum pump is connected to the air outlet.

[0037] In this technical solution, when the vacuum pump is started, negative pressure is generated to absorb paper scraps and foreign matter on the cleaning roller through the adsorption tube. The air with foreign matter then enters the filter box through the connecting pipe. The air first encounters the filter plate. Most of the foreign matter is intercepted by the filter plate and falls into the collection frame, while the clean air is discharged to the outside through the air outlet. As the working time increases, the foreign matter accumulated in the collection frame may gradually increase. In order to maintain the filtering efficiency, regular cleaning is required. The maintenance personnel can use the handle to pull the collection frame out of the filter box, remove the accumulated foreign matter, and put the collection frame back in place for continued use. The filtering structure can ensure that the cleaning system can work continuously and efficiently, while simplifying the maintenance process, making the cleaning and maintenance of the equipment more convenient.

[0038] In the above technical solution, further, a rubber layer is provided on the surface of the flat roller.

[0039] In the technical solution, by providing a rubber layer on the surface of the flat roller, it is beneficial to increase the service life of the bumps on the surface of the embossing roller, reduce the replacement frequency and maintenance cost. Further, the surface of the flat roller is provided with a rubber layer.

[0040] The beneficial effects of the utility model are:

[0041] 1. When multiple layers of paper pass between the flat roller and the embossing roller with bumps, the bumps on the embossing roller exert pressure on the paper to form an embossing effect, which causes physical interlocking between the layers of paper, thereby enhancing the bonding force between the layers and achieving the purpose of not being easy to peel off. Since this process does not involve the use of chemical adhesives, it can maintain the softness and smoothness of the paper, and is also more environmentally friendly.

[0042] 2. The hemispherical surface and the inclined surface can make the transition from the outer wall of the protrusion to the hemispherical top smoother, which helps the paper to enter and exit the embossing area more smoothly during the embossing process and reduces the tearing or damage of the paper during the embossing process.

[0043] 3. Through the cooperation between the driving motor, the first bevel gear and the second bevel gear, the cleaning roller can be driven to rotate and the surface of the embossing roller can be cleaned. During the cleaning process, the symmetrically arranged adsorption structure can collect the cleaned foreign matter to prevent the cleaned foreign matter from falling on the paper or floating in the working environment, thereby improving environmental hygiene and paper quality. The cleaning structure ensures the cleanliness of the embossing roller during the working process, maintains the stability of the embossing effect and the consistency of paper quality, and also reduces the frequency and difficulty of equipment maintenance.
