Description

Technical Field

[0001] This utility model relates to the field of molding roller technology, specifically to a molding roller with seam splicing. Background Technology

[0002] The die-cutting roller with seamless splicing is a key piece of equipment used in the production of high-precision printing, packaging, or decorative materials. Its core function is to combine multiple independent die seams (pattern units) into a continuous whole through seamless splicing technology. It is suitable for high-precision printing, packaging, and decorative materials (such as wood grain and metal foil).

[0003] Currently, the traditional coatings on the surface of existing molding rollers are mostly disposable and cannot be reused after use, resulting in high production costs. In addition, the roller surface generates heat during operation, which leads to unstable roller surface temperature and uneven quality of the pressed product pattern. Furthermore, the existing roller body and shaft head are integrated, and local damage can easily lead to the scrapping of the entire roller. On the other hand, some detachable rollers are difficult to install and disassemble, resulting in high maintenance costs.

[0004] Based on this, this utility model designs a die-pressing roller with die seam splicing to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a die-cutting roller for die seam splicing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a die-cutting roller with seam splicing, comprising a roller body, shaft heads, and fastening screws. Shaft heads are installed at both ends of the roller body, and the shaft heads are fixedly connected to the roller body by multiple fastening screws. The roller body comprises a core shaft, a substrate layer, a graphene composite material filling layer, a nanoscale transition layer, and a ceramic coating. The substrate layer is fixedly connected to the outside of the core shaft. The interlayer of the substrate layer is filled with a graphene composite material filling layer. A ceramic coating is disposed on the outside of the substrate layer. A nanoscale transition layer is disposed between the ceramic coating and the substrate layer.

[0007] As a preferred embodiment of this utility model, dovetail grooves are provided on the inner walls of both ends of the mandrel in an annular manner, and screw grooves are provided on the end faces of both ends of the mandrel in an annular manner.

[0008] As a preferred embodiment of this utility model, a heat dissipation through hole is provided in the inner ring of the substrate layer, and a plurality of heat conduction holes are provided in each heat dissipation through hole, and the heat conduction holes are connected to the interlayer in the substrate layer.

[0009] As a preferred embodiment of the present invention, the shaft head includes an outer shaft body, an inner shaft body, a flange, and dovetail blocks. The inner shaft body is fixedly disposed at one end of the outer shaft body. Multiple dovetail blocks are arranged in a ring on the inner shaft body. One end of each of the multiple dovetail blocks is connected to the flange, and the flange is fixedly connected to the outer side of the inner shaft body.

[0010] As a preferred embodiment of this utility model, the flange is provided with a plurality of mounting holes in a ring shape, and each mounting hole is provided with a fastening screw.

[0011] As a preferred embodiment of this utility model, the dovetail block on the inner shaft body is connected to the dovetail groove in the mandrel, and the mounting hole on the flange is correspondingly set to the screw groove on the end face of the mandrel.

[0012] As a preferred embodiment of this invention, the multiple dovetail blocks on the inner shaft are all coated with tungsten carbide.

[0013] As a preferred embodiment of this utility model, the mandrel is made of high-strength alloy steel, and the substrate layer is made of aluminum-magnesium alloy.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model sets a controllable interface nanoscale transition layer between the ceramic coating and the substrate layer, and triggers interface separation through chemical etching or thermal shock to achieve non-destructive peeling and recycling of the ceramic coating, breaking through the limitation of traditional coatings being "one-time scrap" and reducing material costs. Furthermore, by filling the graphene composite material filling layer in the substrate layer sandwich, the heat generated by the high-speed operation of the roller can be absorbed, keeping the roller surface temperature stable. The heat dissipation through holes and heat conduction holes opened in the substrate layer can achieve heat dissipation of the roller, ensuring the quality of the pattern pressed out of the product, and has good practicality.

[0016] 2. This utility model achieves a quick connection between the roller body and the shaft head by machining dovetail groove arrays at both ends of the mandrel and setting matching dovetail block protrusions on the shaft head. It is reinforced by multiple fastening screws. By adopting this split connection structure, the roller body or shaft head can be quickly replaced. Local damage can be replaced individually, avoiding overall scrapping, thereby reducing maintenance costs and having good economic efficiency. Attached Figure Description

[0025] The following will refer to the appendix in the embodiments of this utility model. Figure 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example

[0027] Please see Figure 1-6 The present invention provides the following technical solution: a die-cutting roller with seam splicing, comprising a roller body 1, a shaft head 2 and fastening screws 3. The roller body 1 is equipped with shaft heads 2 at both ends. The shaft heads 2 are fixedly connected to the roller body 1 by a plurality of fastening screws 3. The roller body 1 comprises a core shaft 101, a substrate layer 102, a graphene composite material filling layer 103, a nanoscale transition layer 104 and a ceramic coating 105. The substrate layer 102 is fixedly connected to the outside of the core shaft 101. The interlayer of the substrate layer 102 is filled with a graphene composite material filling layer 103. The ceramic coating 105 is disposed on the outside of the substrate layer 102. A nanoscale transition layer 104 is disposed between the ceramic coating 105 and the substrate layer 102.

[0028] The inner walls of both ends of the mandrel 101 are provided with dovetail grooves 1011 in an annular shape, and the end faces of both ends of the mandrel 101 are provided with screw grooves 1012 in an annular shape.

[0029] A heat dissipation through hole 1021 is provided in the inner ring of the substrate layer 102. Multiple heat conduction holes 1022 are provided in each heat dissipation through hole 1021. The heat conduction holes 1022 are connected to the interlayer in the substrate layer 102.

[0030] The nanoscale transition layer 104 between the substrate layer 102 and the ceramic coating 105 enables the ceramic coating 105 to be peeled off without damage and recycled, breaking through the limitation of traditional coatings being "discarded once" and reducing material costs. At the same time, the graphene composite material filling layer 103 filled in the interlayer can maintain the stability of the roller surface temperature, thereby ensuring the quality of the pattern pressed out of the product.

[0031] The shaft head 2 includes an outer shaft body 201, an inner shaft body 202, a flange 203, and dovetail blocks 204. The inner shaft body 202 is fixedly installed at one end of the outer shaft body 201. Multiple dovetail blocks 204 are arranged in a ring on the inner shaft body 202. One end of each dovetail block 204 is connected to the flange 203. The flange 203 is fixedly connected to the outer side of the inner shaft body 202.

[0032] The flange 203 has multiple mounting holes arranged in a ring, and each mounting hole is equipped with a fastening screw 3.

[0033] The dovetail block 204 on the inner shaft 202 is connected to the dovetail groove 1011 in the spindle 101 respectively, and the mounting hole on the flange 203 is set to correspond to the screw groove 1012 opened on the end face of the spindle 101.

[0034] The multiple dovetail blocks 204 on the inner shaft 202 are all coated with tungsten carbide.

[0035] The mandrel 101 is made of high-strength alloy steel, and the substrate layer 102 is made of aluminum-magnesium alloy.

[0036] The dovetail block 204 provided on the inner shaft body 202 can be matched and engaged with the dovetail groove 1011 in the spindle 101, and the tungsten carbide coating on the surface of the dovetail block 204 can enhance the hardness of the dovetail block 204 and improve its wear resistance.

[0037] The working principle and usage process of this utility model are as follows: In specific use, when it is necessary to peel off the coating on the surface of the roller, the interface separation is triggered by chemical etching or thermal shock, so that the coating is peeled off from the surface of the roller, realizing the recycling and reuse of the ceramic coating, reducing material costs. The graphene composite material filling layer 103 in the interlayer of the substrate layer 102 can absorb the heat generated by the high-speed operation of the roller, keep the roller surface temperature stable, and ensure the quality of the pattern pressed out of the product. When the roller 1 or the shaft head 2 is worn and needs to be replaced, the multiple fastening screws 3 used for connection are unscrewed, and then the dovetail block 204 on the shaft head 2 is removed from the dovetail groove 1011 in the mandrel 101, so that the roller 1 and the shaft head 2 can be separated, which facilitates the installation and disassembly of the roller 1 and the shaft head 2, thereby shortening maintenance time and maintenance costs.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
