Description

TECHNICAL FIELD

[0001] The application relates to the technical field of embossing rollers, in particular to a wear-resistant embossing roller. BACKGROUND

[0002] The existing embossing roller is generally a device for pressing specific patterns or patterns on the surfaces of various materials and is widely applied in industrial production, such as the processing fields of leather, paper and plastic, and the like. The rotation and pressure of the embossing roller can give the materials unique texture appearance and improve the added value of products.

[0003] However, in the current industrial production, the existing embossing roller faces severe challenges in wear resistance. Since the embossing roller needs to continuously and highly frictionally contact the surfaces of various processing materials during the working process, the traditional embossing roller material and structural design are difficult to withstand long-time and high-frequency friction loss, which leads to the phenomena of wear, scratches and even peeling on the surface of the embossing roller. With the aggravation of wear, the surface precision and pattern clarity of the embossing roller are gradually reduced, so that the quality of the pressed products is greatly reduced and cannot meet the increasingly improved production standards and market demand.

[0004] Therefore, it is necessary to provide a wear-resistant embossing roller to solve the above problems.

[0005] It should be noted that the above information disclosed in the background section of the present application is only used to understand the background technology of the concept of the present application, and therefore, it can contain information which does not constitute prior art. CONTENT OF THE UTILITY MODEL

[0006] The utility model aims at providing a wear-resistant embossing roller to solve the problems raised in the background technology.

[0007] The technical scheme adopted by the application to solve the technical problems is:

[0008] A wear-resistant embossing roller, comprising a shaft rod and an outer cylinder sleeved on the shaft rod, a plurality of limiting plates are integrally formed on the side wall of the middle section of the shaft rod, a cavity for the shaft rod to pass through is provided in the inner part of the outer cylinder, a limiting groove is provided on the side wall of the cavity in one circle, and the plurality of limiting plates are respectively inserted into the limiting grooves;

[0009] The outer surface of the outer cylinder is sprayed with a ceramic nano layer, and the ceramic nano layer and the outer surface of the outer cylinder form a wavy gradient structure, and the outer layer of the ceramic nano layer is sprayed with a tungsten carbide layer.

[0010] The outer cylinder is fixedly installed with a mounting disc on each side through a screw.

[0011] Preferably, the side wall of the shaft rod and the plurality of limiting plate staggered surfaces are provided with buffer strips, which are arranged in the gap between the side wall of the shaft rod and the plurality of limiting plate staggered surfaces and the cavity.

[0012] Preferably, the two ends of the outer cylinder are integrally formed with limiting rings, and the side wall of the mounting disc is provided with a ring groove.

[0013] Preferably, the inside of the mounting disc is provided with a shaft hole, and the two ends of the shaft rod are respectively inserted into the shaft hole.

[0014] Preferably, the inside of the mounting disc is provided with a mounting groove, and the mounting groove is provided with a disc.

[0015] Preferably, the inner ring of the disc is in a conical ring structure, and a buffer groove is formed along the ring.

[0016] The beneficial effects of the present application are:

[0017] 1. The shaft rod and the outer cylinder are connected by limiting plates and limiting grooves. When the surface of the outer cylinder is affected by wear and tear, it can be easily disassembled from the shaft rod and replaced with a new outer cylinder, without the need to replace the entire embossing roller, greatly improving the maintenance efficiency of the equipment, reducing the downtime caused by equipment replacement, and reducing maintenance costs.

[0018] 2. The buffer strips arranged between the side wall of the shaft rod and the cavity of the outer cylinder play a key buffering and damping role during the rotation of the embossing roller. When the equipment is impacted or vibrated, the buffer strips can absorb part of the energy, effectively reducing the direct collision and friction between the shaft rod and the outer cylinder. This buffering mechanism avoids rapid wear caused by local stress concentration, prolongs the service life of the shaft rod and the outer cylinder, and further enhances the overall wear resistance of the embossing roller.

[0019] In addition, the ceramic nanolayer, with its good wear resistance, high temperature resistance and corrosion resistance, significantly improves the hardness and smoothness of the outer cylinder surface, and the gradient structure further enhances the bonding force with the outer cylinder, making the coating more firm. The outer layer of tungsten carbide layer further enhances the hardness of the outer cylinder surface, enabling it to withstand greater pressure and friction. Through the composite coating structure, the wear resistance of the embossing roller is greatly improved, which can maintain stable embossing effect in long-term harsh working environment and reduce the problem of product quality decline caused by wear and tear.

[0020] In addition to the purposes, features and advantages described above, the present application has other purposes, features and advantages. The present application will be described in further detail below with reference to the drawings. BRIEF DESCRIPTION OF DRAWINGS

[0035] Please refer to Figures 1-5 The embodiments provided by the utility model have the advantages that:

[0036] The utility model provides a kind of wear-resistant embossing roller, including shaft 1 and sleeve in the outer cylinder 2 of shaft 1, a plurality of limit plates 12 are integrally formed in the side wall of the middle section of shaft 1, the cavity 21 for the shaft 1 is passed through and is set in the inside of outer cylinder 2, the side wall of cavity 21 is correspondingly provided with a plurality of limit grooves 22, and the plurality of limit plates 12 are respectively inserted into limit groove 22;

[0037] By the cooperation of limit plate 12 and limit groove 22, the circumferential rotation of outer cylinder 2 relative to shaft 1 is limited, so that outer cylinder 2 can rotate with shaft 1, and this structure can also withstand a certain torque, ensuring that the power is transmitted from shaft 1 to outer cylinder 2, so that outer cylinder 2 can stably rotate around shaft 1 during work, realizing the embossing function. This connection method facilitates the installation and removal of outer cylinder 2, making it easy to maintain and replace parts of the embossing roller. If the surface of outer cylinder 2 is damaged, it can be replaced directly without the need to replace the entire embossing roller, saving costs.

[0038] It is worth noting that the side wall of shaft 1 and the plurality of limit plates 12 are positioned on the surface of the side wall of shaft 1 and the plurality of limit plates 12, and a buffer strip 4 is disposed in the gap between the side wall of shaft 1 and the plurality of limit plates 12. When shaft 1 and outer cylinder 2 are impacted or vibrated during rotation, buffer strip 4 can act as a buffer and shock absorber. It can absorb part of the energy, reduce direct collision and friction between shaft 1 and outer cylinder 2, prolong the service life of shaft 1 and outer cylinder 2, reduce the risk of component damage caused by vibration and impact, improve the stability and reliability of the embossing roller, and also reduce noise and vibration during work, avoiding local overload wear.

[0039] The outer surface of outer cylinder 2 is sprayed with a ceramic nano layer 25, and the ceramic nano layer 25 and the outer surface of outer cylinder 2 form a wavy gradient structure. The outer layer of ceramic nano layer 25 is sprayed with a tungsten carbide layer 24. The ceramic nano layer 25 has good wear resistance, high temperature resistance and corrosion resistance, which can improve the hardness and smoothness of the surface of outer cylinder 2. The wavy gradient structure increases the bonding force between the coating and outer cylinder 2, making the coating more secure. The tungsten carbide layer 24 further improves the hardness and wear resistance of the surface of outer cylinder 2, which can withstand greater pressure and friction, greatly improving the wear resistance of the embossing roller, allowing it to maintain good embossing effect during long-term work, reducing the decline in embossing quality due to wear, and also resisting various harsh working environments, prolonging the service life of the embossing roller;

The insertion of the limiting ring 23 and the ring groove 31 further limits the movement of the outer cylinder 2 in the axial direction, so that the outer cylinder 2 is more stable during rotation.

[0041] Further, the mounting disc 3 is internally provided with the mounting groove 33, the mounting groove 33 is provided with the disc 34, the inner ring of the disc 34 is in a conical ring structure, and is provided with the buffer groove 35 along a circle, the conical ring inner ring of the disc 34 and the buffer groove 35 can play a certain buffering role during the embossing process, when the embossing roller is impacted by external force, the disc 34 can absorb energy through its deformation and the compression of the buffer groove 35, so as to protect the internal structure and the external coating of the embossing roller, meanwhile, it is also helpful to improve the embossing quality and reduce the problems such as uneven embossing caused by impact.
