Description

Technical Field

[0001] This utility model relates to the field of paper embossing technology, and in particular to an embossing device that can increase air bubbles in paper. Background Technology

[0002] Paper embossing is a common process mainly used to enhance the aesthetics and functionality of paper. Paper embossing involves passing the raw paper between metal rollers with engraved patterns, causing the raw paper to undergo plastic deformation and present the same pattern and texture as the metal roller surface. By pressing the paper surface with great force, an uneven surface is formed, thereby increasing friction and adhesion, while also improving water absorption and softness.

[0003] Existing paper embossing devices simply emboss the paper by passing it between two metal rollers engraved with patterns. Although this can increase the paper's friction and adhesion, the printing is done by rigidly pressing the paper onto it. As a result, the paper becomes harder when using embossed paper, and the feel is poor.

[0004] To address this problem, we propose an embossing device that increases air bubbles in the paper. Utility Model Content

[0005] The purpose of this invention is to provide an embossing device that can increase air bubbles in paper, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An embossing device for increasing paper air bubbles, comprising:

[0008] Two pattern rollers, each with a rotary joint at both ends, are rotatably mounted to the rollers via mounting flanges.

[0009] The two pattern rollers are arranged side by side, and two paper guide rollers are provided below the two pattern rollers. A main printing paper and a secondary printing paper are respectively provided outside the two pattern rollers. The main printing paper and the secondary printing paper pass through the two paper guide rollers and the pattern rollers respectively and are bonded together between the two pattern rollers to form the base paper.

[0010] Furthermore, the printing roller is provided with a step, and a printing cylinder is installed on the outer sleeve of the step. The printing cylinder is provided with multiple patterns and air holes, and the air holes are connected to two rotary joints.

[0011] Furthermore, the two flower rollers are arranged to rotate relative to each other.

[0012] Furthermore, multiple patterns are evenly distributed in an array outside the printing cylinder, and multiple air holes are evenly distributed in an array outside the printing cylinder, with each pattern and air hole corresponding to the other.

[0013] Furthermore, the rotary joint is configured in a curved shape.

[0014] Furthermore, the two additional printing papers are located on either side below the two printing rollers.

[0015] Compared with the prior art, the beneficial effects of this utility model are at least as follows:

[0016] By setting up rotary joints and printing cylinders, the main printing paper and secondary printing paper are stretched through the guide rollers and then wound around two pattern rollers respectively. As the two pattern rollers rotate, they drive the main and secondary printing papers to rotate and press them together to form the base paper. Simultaneously, during the embossing process, compressed air is blown in through the rotary joints at both ends of the pattern rollers and out through the air holes. At this time, during the embossing process, the patterns on the surfaces of the two pattern rollers work together to fill the patterned areas of the paper with air. When forming the base paper, the patterned areas of the base paper are bulged out, forming raised patterns. The air pressure inside the raised patterns is kept consistent with the outside air pressure. At this time, the raised patterns have… With slight deformation capability, the polish of the embossed paper increases, resulting in a better feel during use. When embossing under negative pressure, air is drawn in through the rotary joint, creating negative pressure inside the embossing rollers. At this time, because the air holes are blocked by the paper, negative pressure is formed. During the embossing process, the patterns on the surfaces of the two embossing rollers work together to fill the non-patterned parts of the paper with air. When forming the base paper, the non-patterned parts of the base paper are bulging, while the patterned parts are pressed tightly together, forming a recessed pattern. This keeps the air pressure inside the non-patterned parts consistent with the outside air pressure. At this time, the non-patterned parts have slight deformation capability, increasing the polish of the embossed paper and resulting in a better feel during use.

[0017] This invention allows for selective air filling of both patterned and non-patterned areas of the paper during embossing, increasing the paper's sturdiness and improving its usability. Attached Figure Description

[0024] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0025] Please see Figures 1-5 An embossing device for increasing paper air bubbles, comprising:

[0026] Two pattern rollers 1 are arranged to rotate relative to each other. Rotary joints 3 are installed at both ends of the pattern rollers 1. It should be noted that the rotary joints 3 are bent. The pattern rollers 1 and the rotary joints 3 are rotatably installed through mounting flanges 2. It should be noted that the pattern rollers 1 are provided with steps. A printing cylinder 10 is installed on the outer side of the steps. The printing cylinder 10 is provided with multiple patterns 4 and air holes 5. The air holes 5 are connected to the two rotary joints 3. Furthermore, the multiple patterns 4 are evenly distributed in an array outside the printing cylinder 10, and the multiple air holes 5 are evenly distributed in an array outside the printing cylinder 10. The patterns 4 and air holes 5 correspond one-to-one.

[0027] Two pattern rollers 1 are arranged side by side. Two guide rollers 6 are provided below the two pattern rollers 1. Main printing paper 7 and secondary printing paper 8 are respectively provided outside the two pattern rollers 1. It should be noted that the two secondary printing papers 8 are located on both sides below the two pattern rollers 1. The main printing paper 7 and secondary printing paper 8 pass through the two guide rollers 6 and the pattern rollers 1 respectively and are bonded together between the two pattern rollers 1 to form the base paper 9.

[0028] Through the above technical features: when printing on paper, the main printing paper 7 and the secondary printing paper 8 are stretched through the guide roller 6 and then wound around the two pattern rollers 1 respectively. When the two pattern rollers 1 rotate, they drive the main printing paper 7 and the secondary printing paper 8 to rotate and press them together to form the base paper 9. At the same time, when embossing by blowing air, compressed air is blown in through the rotary joints 3 at both ends of the pattern rollers 1 and blown out through the air holes 5. During the embossing process, the patterns 4 on the surfaces of the two pattern rollers 1 are matched to make the patterns 4 on the paper part... When the paper is filled with air, the pattern 4 part of the paper is bulging out during the formation of the base paper 9, forming a raised pattern. When the paper is embossed under negative pressure, air is drawn in through the rotary joint 3, creating a negative pressure inside the pattern roller 1. At this time, the air hole 5 is blocked by the paper, thus creating a negative pressure. During the embossing process, the pattern 4 on the surfaces of the two pattern rollers 1 cooperates to fill the non-patterned part of the paper with air. When the paper is formed, the non-patterned part of the paper is bulging out during the formation of the base paper 9, and the pattern 4 part is pressed tightly together, forming a recessed pattern.

[0029] Working principle:

[0030] 1) Printing by air blowing: When printing on paper, the main printing paper 7 and the secondary printing paper 8 are stretched through the guide roller 6 and then wound around the two pattern rollers 1 respectively. When the two pattern rollers 1 rotate, they drive the main printing paper 7 and the secondary printing paper 8 to rotate and press them together to form the base paper 9. At the same time, compressed air is blown in through the rotary joints 3 at both ends of the pattern rollers 1 and blown out through the air holes 5. During the embossing process, the pattern 4 on the surface of the two pattern rollers 1 cooperates to fill the pattern 4 part of the paper with air. When the base paper 9 is formed, the pattern 4 part of the base paper 9 is bulging and forms a raised pattern.

[0031] 2) Negative pressure printing: When printing on paper, the main printing paper 7 and the secondary printing paper 8 are stretched through the guide roller 6 and then wound around the two pattern rollers 1 respectively. When the two pattern rollers 1 rotate, they drive the main printing paper 7 and the secondary printing paper 8 to rotate and press them together to form the base paper 9. At the same time, air is sucked in through the rotary joint 3 to form a negative pressure inside the pattern roller 1. At this time, the air hole 5 is blocked by the paper, so a negative pressure is formed. During the embossing process, the pattern 4 on the surface of the two pattern rollers 1 cooperates to fill the non-patterned part of the paper with air. When forming the base paper 9, the non-patterned part of the base paper 9 is bulging, and the pattern 4 is pressed tightly to form a recessed pattern.
