Description

Technical Field

[0001] This utility model relates to the field of coating technology, and in particular to a glue control roller. Background Technology

[0002] The control roller is a key component in precision coating equipment, and the flatness and wear resistance of its roller surface directly determine the uniformity of the coating effect. In actual use, since the material to be coated (such as film and paper) usually passes through the middle of the roller in a width-length pattern, the middle area of ​​the control roller comes into the most frequent contact with the material, resulting in much greater wear than the ends.

[0003] This uneven wear will cause concave wear on the roller surface, resulting in a thin coating in the middle and a thick coating on both sides, which seriously affects product quality.

[0004] Currently, the main ways to solve this problem are to increase the overall hardness of the roller surface or replace the entire roller body, which is costly and does not fundamentally solve the problem of uneven wear. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a glue control roller that is easy to maintain and disassemble.

[0006] The purpose of this utility model is achieved through the following technical solution: a control roller, including a bearing shaft, a sealing plate, and a roller sleeve assembly; the bearing shaft is mounted on the machine body; the sealing plate is mounted on the bearing shaft, and the sealing plate has an outer step on the side near the roller sleeve assembly; the roller sleeve assembly is mounted between two sealing plates and tightly connected, the roller sleeve assembly includes a main roller sleeve, the main roller sleeve has a tubular structure, and the inner walls at both ends of the main roller sleeve are provided with outer steps for docking with the sealing plate.

[0007] By utilizing the interlocking of the outer step of the sealing plate and the inner step of the main roller sleeve, the roller sleeve assembly can be quickly installed and positioned. When there is local wear, only the worn roller sleeve part can be disassembled and replaced, without replacing the entire roller body, which greatly reduces maintenance costs and time.

[0008] The present invention is further configured such that the main roller sleeve is provided with a ceramic layer.

[0009] The ceramic layer has extremely high hardness and wear resistance, which can effectively resist the wear of the scraper and materials, and significantly extend the service life of the main working area.

[0010] The present invention is further configured such that the main roller sleeve is provided with a tungsten carbide layer.

[0011] The tungsten carbide layer also possesses excellent wear resistance and a certain degree of toughness, making it a high-performance wear-resistant coating suitable for high-load working conditions.

[0012] The present invention is further configured such that: the roller sleeve assembly includes a first roller sleeve, a second roller sleeve and a third roller sleeve, the inner sidewalls at both ends of the first roller sleeve are provided with inner steps, one end of the second roller sleeve and the third roller sleeve are provided with inner steps and the other end is provided with outer steps, the second roller sleeve and the third roller sleeve are respectively provided at both ends of the first roller sleeve, and the end face of the third roller sleeve is connected to the sealing plate.

[0013] By designing the roller sleeve assembly as a multi-segment splicing structure, the first roller sleeve, located in the middle and experiencing the most severe wear, can be made of the most wear-resistant material, while the second and third roller sleeves at both ends can be made of materials with slightly lower wear resistance. This optimizes manufacturing costs while ensuring overall wear resistance.

[0014] The present invention is further configured such that: the outer surfaces of the first roller sleeve and the second roller sleeve are provided with mesh holes.

[0015] The cell structure transforms the control roller into a gravure anilox roller, enabling precise metering and transfer of glue or ink, which is key to achieving quantitative coating.

[0016] Strengthening the central area, where wear is most severe, can maintain the volumetric accuracy of the cells for a long time, thereby ensuring the uniformity of coating.

[0017] The present invention is further configured such that the wear resistance of the first roller sleeve is greater than that of the second roller sleeve, which is greater than that of the third roller sleeve.

[0018] This wear resistance gradient design, which decreases from the middle to both ends, matches the actual wear distribution pattern.

[0019] This utility model has the following beneficial effects: The separate roller sleeve assembly and sealing plate combination structure allows for independent replacement of any roller sleeve when wear exceeds the standard, without scrapping the entire roller body, significantly reducing maintenance costs and downtime.

[0020] By segmenting the roller sleeve assembly and decreasing its wear resistance from the middle to both ends, the most severely worn areas are precisely reinforced. This design makes the wear across the entire roller surface more uniform, fundamentally solving the problem of excessive wear in the middle and significantly extending the overall service life of the control roller.

[0021] By using the most expensive wear-resistant materials, such as ceramics and tungsten carbide, only in the most needed locations, the high costs associated with using high-performance materials throughout are avoided, achieving the best balance between performance and economic benefits.

[0022] By maintaining the long-term flatness of the roller surface and the precision of the cells, the coating amount is kept stable and uniform throughout the entire life cycle, effectively improving the consistency of product quality. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below, but the scope of protection of the present invention is not limited to the following description.

[0032] Example 1 like Figure 1 As shown, a control roller includes a bearing shaft 3, a sealing plate 2, and a roller sleeve assembly 1.

[0033] The bearing shaft 3 is mounted on the machine body; like Figure 2 As shown, the sealing plate 2 is mounted on the bearing shaft 3, and the sealing plate 2 has an outer step 21 on the side near the roller sleeve assembly 1; The roller sleeve assembly 1 is tightly connected between two sealing plates 2. The roller sleeve assembly 1 includes a main roller sleeve 11, which has a tubular structure. Both ends of the main roller sleeve 11 have outer steps 21 for docking with the sealing plates 2. By using the outer steps 21 of the sealing plates 2 and the inner steps 15 of the main roller sleeve 11 to engage with each other, the roller sleeve assembly 1 can be quickly installed and positioned. When there is local wear, only the worn roller sleeve part can be disassembled and replaced, without replacing the entire roller body, which greatly reduces maintenance costs and time.

[0034] As a preferred option: such as Figure 2As shown, the outer surface of the main roller sleeve 11 is provided with a ceramic layer 16; the ceramic layer 16 has extremely high hardness and wear resistance, which can effectively resist the wear of the scraper and the material, and significantly extend the service life of the main working area.

[0035] As a preferred option: such as Figure 2 As shown, the outer surface of the main roller sleeve 11 is provided with a tungsten carbide layer; the tungsten carbide layer also has excellent wear resistance and a certain toughness, and is a high-performance wear-resistant coating suitable for high-load working conditions.

[0036] As a preferred option: such as Figure 2 As shown, the outer surface of the main roller sleeve 11 is provided with a ceramic metal layer; by dividing the main roller sleeve 11 into a base layer that contacts the sealing plate 2 and a wear-resistant layer for precision coating, the wear resistance effect can be extended while saving costs; In this embodiment, the connection method between the main roller sleeve 11 and the sealing plate 2 can be an interference connection method such as oil bath heating.

[0037] In this embodiment, the existing technologies of the body, bearing shaft 3 and sealing plate 2 will not be described in detail.

[0038] Example 2 The difference between Example 2 and Example 1 is that the following adjustments are made to address the issue of the central control roller becoming damaged due to excessively rapid sagging in the center; like Figure 4 As shown, the roller sleeve assembly 1 includes a first roller sleeve 12, a second roller sleeve 13, and a third roller sleeve 14. The inner sidewalls at both ends of the first roller sleeve 12 are provided with inner steps 15. One end of the second roller sleeve 13 and the third roller sleeve 14 are provided with inner steps 15, and the other end is provided with outer steps 21. The second roller sleeve 13 and the third roller sleeve 14 are respectively provided at both ends of the first roller sleeve 12. The end face of the third roller sleeve 14 is connected to the sealing plate 2. By designing the roller sleeve assembly 1 as a multi-segment splicing structure, the first roller sleeve 12, which is located in the middle and suffers the most severe wear, can be independently selected with the most wear-resistant material, while the second and third roller sleeves 14 at both ends can be selected with materials with slightly lower wear resistance. This optimizes the manufacturing cost while ensuring the overall wear resistance.

[0039] The outer surfaces of the first roller sleeve 12 and the second roller sleeve 13 are provided with holes 17; the structure of the holes 17 makes the glue control roller a gravure anilox roller, which can accurately measure and transfer glue or ink, and is the key to achieving quantitative coating.

[0040] Strengthening the central area, where wear is most severe, can maintain the volumetric accuracy of the 17 cells for a long time, thereby ensuring the uniformity of coating.

[0041] The wear resistance of the first roller sleeve 12 is greater than that of the second roller sleeve 13, which is greater than that of the third roller sleeve 14. This wear resistance gradient design, which decreases from the middle to both ends, matches the actual wear distribution pattern.

[0042] In this embodiment, a mesh wall 18 is provided at the middle position of the first roller sleeve 12, and mesh holes 17 are provided on both sides of the mesh wall 18 of the first roller sleeve 12. Mesh holes 17 are provided on the outer surface of the second roller sleeve 13. The mesh holes 17 are evenly spaced along the circumference of the first roller sleeve 12 or the second roller sleeve 13.

[0043] Example 3 The difference between Example 3 and Examples 1 and 2 is that the technical solution provided is to address how to achieve a protective effect when the ceramic layer 16 is assembled in an oil bath hot press. like Figure 2 As shown, the bearing shaft 3 includes a shaft core 32 connected to the machine body and an inner liner shaft 31 sleeved on the shaft core 32. Both ends of the inner liner shaft 31 are provided with a shoulder portion 312 for limiting excessive compression and a bearing portion 311 for connection. The bearing portion 311 is interference-fitted with the connection hole on the sealing plate 2. The shoulder portion can effectively prevent the ceramic layer 16 from cracking or chipping due to excessive compression.

[0044] The shaft core 32 is existing technology and can be either a two-section or a one-piece structure. Here, the two-section connection method is optimal.

[0045] This utility model has the following beneficial effects: The roller sleeve assembly 1 and the sealing plate 2 are combined in a split structure. When the wear of any roller sleeve exceeds the standard, it can be replaced independently without scrapping the entire roller body, which significantly reduces maintenance costs and downtime.

[0046] By segmenting the roller sleeve assembly 1 and decreasing its wear resistance from the middle to both ends, the most severely worn areas are precisely reinforced. This design makes the wear of the entire roller surface more uniform, fundamentally solving the problem of excessive wear and significantly extending the total service life of the control roller.

[0047] By using the most expensive wear-resistant materials, such as ceramics and tungsten carbide, only in the most needed locations, the high costs associated with using high-performance materials throughout are avoided, achieving the best balance between performance and economic benefits.

[0048] By maintaining the long-term flatness of the roller surface and the precision of the 17-cell mesh, the coating amount is kept stable and uniform throughout the entire life cycle, effectively improving the consistency of product quality.

[0049] 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.
