Description

Technical Field

[0001] This utility model relates to the field of paper embossing technology, specifically to an anti-counterfeiting paper anti-counterfeiting layer thickness adjustment molding structure. Background Technology

[0002] By pressing together convex and concave molds, paper products can be imprinted with three-dimensional relief patterns, enhancing their three-dimensional effect.

[0003] In related technologies, a solution for a packaging box embossing device (publication number CN220114123U) was found. The packaging box substrate is placed on the top surface of the embossing table, and the hydraulic cylinder is activated to push the pressure plate through the output end of the hydraulic cylinder. The pressure plate moves downward through the guide hole opened on the top surface and along the guide post installed on the top surface of the embossing table, so that the convex mold on the bottom surface of the pressure plate presses down on the packaging box substrate and cooperates with the concave mold to complete the embossing operation on the packaging box substrate.

[0004] However, the deformation range of paper of different thicknesses and materials is limited. The above solution uses convex and concave dies to press the paper. When different types of paper need to be pressed, the convex and concave dies need to be replaced, which delays the paper pressing and affects the pressing efficiency. It is not convenient to use. Utility Model Content

[0005] The purpose of this invention is to provide a molding structure for adjusting the thickness of the anti-counterfeiting layer of anti-counterfeiting 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: a molding structure for adjusting the thickness of the anti-counterfeiting layer of anti-counterfeiting paper, including a base plate, a bracket installed on the base plate, and a pressure plate connected to the upper end of the bracket via a first oil cylinder, wherein the pressure plate is slidably connected to the bracket;

[0007] Upper template, which is connected to pressure plate, and a protruding template is inserted into the upper template;

[0008] The lower template is installed on the surface of the base plate, and a recessed template is inserted into the lower template;

[0009] The positioner is provided in two sets and is connected to the convex and concave templates respectively. The positioner controls the movement of the convex and concave templates, which can change the thickness of the pattern on the paper and can be used to imprint on different types of paper.

[0010] Furthermore, an n-shaped frame is installed at the lower end of the first hydraulic cylinder, and the n-shaped frame is connected to the upper template. The adjusting device includes a second hydraulic cylinder and a top plate connected to the second hydraulic cylinder. The convex template and the concave template are connected to the corresponding top plate. A positioning group is provided on the side of the top plate. The positioning group is connected to the corresponding bottom plate and the n-shaped frame. The positioning group includes a light rod, and a sliding sleeve is sleeved on the light rod to improve the moving accuracy of the convex template and the concave template and ensure that the paper printing will not be misaligned.

[0011] Furthermore, heating rods are inserted inside the convex and concave templates to heat the paper, soften the paper fibers, and make it easier to shape during the printing process.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) The paper is placed on the lower template. The positions of the convex template and the concave template are adjusted based on the paper thickness and material. The second oil cylinder controls the movement of the convex template and the concave template so that the protrusion length of the convex template on the upper template corresponds to the concave amplitude of the concave template on the lower template. The convex template and the concave template press the paper. There is no need to change the upper template and the lower template, which makes it easy to continuously press different papers and is more efficient.

[0014] (2) The heating rod heats the convex and concave templates. It can be heated when printing on paper to soften the paper fibers. The paper can achieve clearer concave and convex texture details. Through heating and shaping, the concave and convex structure formed on the paper surface is more stable, while reducing the rebound phenomenon and ensuring the long-term maintenance of the three-dimensional effect.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Please see Figure 1-4 This utility model provides a technical solution: a molding structure for adjusting the thickness of the anti-counterfeiting layer of anti-counterfeiting paper, including a base plate 4, a bracket 8 installed on the base plate 4, and a pressure plate 7 connected to the upper end of the bracket 8 through a first oil cylinder 11, and the pressure plate 7 is slidably connected to the bracket 8, thereby improving the accuracy of the first oil cylinder 11 driving the pressure plate 7 to move up and down.

[0023] Upper template 6 is connected to pressure plate 7. A protruding template 9 is inserted into the upper template 6. The protruding template 9 can slide up and down to adjust the protrusion length.

[0024] The lower template 5 is installed on the surface of the base plate 4. A concave template 14 is inserted into the lower template 5. The lower template 5 can be moved up and down to change the degree of concavity of the surface of the lower template 5.

[0025] The adjuster is provided in two sets and is connected to the convex template 9 and the concave template 14 respectively, so as to realize the automatic adjustment of the convex template 9 and the concave template 14 and also to support the convex template 9 and the concave template 14.

[0026] In this embodiment, as Figure 1 As shown, a control cabinet 1 is installed on the lower surface of the base plate 4. A screw hole plate 2 is provided on the side of the control cabinet 1. A support foot 3 is screwed onto the screw hole plate 2. The control cabinet 1 has storage space. Tightening the support foot 3 can ensure that the support foot 3 is stably in contact with the ground and provides horizontal support for the control cabinet 1.

[0027] In this embodiment, as Figure 1 As shown, an n-shaped frame 10 is installed at the lower end of the first hydraulic cylinder 11. The n-shaped frame 10 is connected to the upper template 6. The second hydraulic cylinder 17, which drives the convex template 9 to move, is connected to the n-shaped frame 10 to ensure that the second hydraulic cylinder 17 stably supports the convex template 9.

[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 3 As shown, heating rods 13 are inserted inside the convex template 9 and the concave template 14. The heating rods 13 heat the convex template 9 and the concave template 14. When the paper comes into contact with the convex template 9 and the concave template 14, it is heated and softens the paper fibers, making it easier to shape during the printing process.

[0029] In this embodiment, as Figure 2 As shown, the adjusting device includes a second hydraulic cylinder 17 and a top plate 12 connected to the second hydraulic cylinder 17. The convex template 9 and the concave template 14 are connected to the corresponding top plate 12, and the second hydraulic cylinder 17 connected to the concave template 14 is connected to the bottom plate 4.

[0030] In this embodiment, as Figure 1 and Figure 2 As shown, the top plate 12 is provided with a positioning group on its side. The positioning group is connected to the corresponding bottom plate 4 and n-shaped frame 10 to improve the accuracy of the movement of the convex template 9 and the concave template 14 and prevent the convex template 9 and the concave template 14 from shifting.

[0031] In this embodiment, as Figure 1 and Figure 2 As shown, the positioning group includes a light rod 15, on which a sliding sleeve 16 is sleeved. The light rod 15 that positions the convex template 9 is connected to the n-shaped frame 10, and the light rod 15 that positions the concave template 14 is connected to the base plate 4.

[0032] In this embodiment, as Figure 1 As shown, a pressure sensor 18 is installed between the n-shaped frame 10 and the first oil cylinder 11, which can detect the pressure on the paper. When the pressure exceeds the threshold, the first oil cylinder 11 controls the convex template 9 to move upward to prevent the paper from being crushed.

[0033] Specifically, during use, the positions of the convex template 9 and the concave template 14 are changed according to the material and thickness of the paper. The upper second oil cylinder 17 drives the convex template 9 to move through the top plate 12, changing the degree of protrusion of the convex template 9 on the upper template 6. The lower second oil cylinder 17 drives the concave template 14 to move through the top plate 12, changing the degree of concavity of the concave template 14 on the lower template 5. When printing on thinner paper, the protrusion of the convex template 9 and the concavity of the concave template 14 are reduced. For some thicker paper, the protrusion of the convex template 9 and the concavity of the concave template 14 can be increased.

[0034] The paper is placed on the lower template 5. The first oil cylinder 11 drives the pressure plate 7 and the upper template 6 to move down through the n-shaped frame 10. The convex template 9 cooperates with the concave template 14 to press a three-dimensional pattern on the paper. The heat from the heating rod 13 is transferred to the paper through the convex template 9 and the concave template 14 to ensure that the paper can achieve a clearer concave and convex texture detail and achieve the heating and shaping of the pattern.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
