Description

Technical Field

[0001] This application relates to the field of aluminum roller processing technology, and in particular to a plug structure for aluminum roller surface treatment. Background Technology

[0002] Aluminum rollers, as an important industrial piece of equipment, are primarily made of aluminum alloy and are widely used in various industries due to their lightweight, high strength, and excellent thermal conductivity. With continuous advancements in industrial technology and increasingly stringent market demands for product quality, especially in printing, packaging, and metal processing, aluminum rollers, with their unique physical and chemical properties, have become an ideal choice for meeting high-standard production requirements. The use of aluminum rollers not only improves production efficiency but also promotes environmental protection and sustainable development, aligning with modern industry's pursuit of resource conservation and environmental protection.

[0003] To improve the surface properties of aluminum rollers, anodizing is performed. This process involves using aluminum or aluminum alloy as the anode, placing it in an electrolyte solution, and electrolyzing it to form a thin film of aluminum oxide on its surface. Anodizing creates an oxide film on the surface of the aluminum roller, thereby improving its corrosion resistance, wear resistance, and other properties.

[0004] However, since the aluminum roller is a hollow structure, the surface treatment requires blocking the openings at both ends of the aluminum roller. Currently, people usually use rubber plugs for blocking. In order to increase the sealing effect between the rubber plug and the aluminum roller, the rubber plug is usually inserted into the end of the aluminum roller in an interference fit manner. However, the interference fit rubber plug is not easy to pull out, which is inconvenient and needs to be improved. Utility Model Content

[0005] To facilitate sealing of the ends of aluminum rollers, this application provides a plug structure for surface treatment of aluminum rollers.

[0006] The plug structure for aluminum roller surface treatment provided in this application adopts the following technical solution:

[0007] A plug structure for surface treatment of aluminum rollers includes a plugging shell, an air bladder, and a compression component. The plugging shell is inserted into the end of the aluminum roller. A sealing ring is provided on the outer wall of the plugging shell for abutting against the end of the aluminum roller. The plugging shell has a compression chamber inside, and the outer wall of the plugging shell has multiple abutment grooves communicating with the compression chamber. The air bladder is installed in the compression chamber, and an opening communicating with the compression chamber is provided on one side of the plugging shell. The compression component passes through the opening and is used to compress the air bladder. The compression component is fixed to the plugging shell by a fixing component.

[0008] When the airbag is in the first state, all the airbags are in the compression chamber; when the airbag is in the second state, the airbag is partially inserted through the clamping groove and abuts against the inner wall of the aluminum roller.

[0009] By adopting the above technical solution, when the sealing shell is inserted into the end of the aluminum roller, the sealing ring can tightly abut against the end of the aluminum roller, forming a preliminary sealing effect. The airbag is then compressed by the compression component, causing it to partially extend from the compression chamber and pass through the abutment groove, abutting against the inner wall of the aluminum roller. At this point, the airbag is in its second state. In this state, the airbag increases the friction between the sealing shell and the inner wall of the aluminum roller, and the tight abutment between the airbag and the inner wall of the aluminum roller increases the tensile strength of the sealing shell, thereby improving the stability of the seal on the end of the aluminum roller.

[0010] When the airbag is switched to the first state, the airbag is fully inserted into the compression chamber, which makes it easier to remove the sealing shell from the aluminum roller. This avoids the problem of traditional rubber plugs being difficult to remove due to interference fit, and improves the convenience of operation.

[0011] Optionally, the end of the abutment groove is offset from the end of the adjacent tightening groove.

[0012] By adopting the above technical solution, the staggered arrangement of the end of the abutment groove with the end of the adjacent abutment groove can effectively increase the stability of the sealing shell fixed inside the aluminum roller. This design makes the airbag more evenly stressed when it expands, avoiding structural failure caused by stress concentration, thereby improving the sealing performance and connection reliability between the sealing shell and the inner wall of the aluminum roller.

[0013] Optionally, a spring is provided inside the airbag, and the elastic force of the spring is used to drive the airbag into a first state.

[0014] By adopting the above technical solution, a spring is installed inside the airbag. The elastic force of the spring can drive the airbag to remain in the first state, that is, the airbag is completely located in the compression chamber, so that the structure can be reused.

[0015] Optionally, the fixing component includes a first threaded portion disposed on the outer wall of the compression member and a second threaded portion disposed on the inner wall of the opening, wherein the first threaded portion and the second threaded portion cooperate with each other.

[0016] By adopting the above technical solution, the sealing shell and the compression component are fixedly connected by threaded engagement. This structural design allows the compression component to be stably held in the designated position after squeezing the airbag, avoiding the compression component from loosening due to external force and affecting the sealing effect.

[0017] Optionally, anti-slip grooves are provided on the outer wall of the compression component.

[0018] By adopting the above technical solution, the anti-slip groove increases the friction when the operator holds the compression component, making it easier to apply force, thereby facilitating the installation and disassembly of the sealing shell and improving ease of use.

[0019] Optionally, the fixing component includes a bolt, the sealing housing has a first threaded groove communicating with the opening; the outer wall of the compression component has a plurality of second threaded grooves, and the bolt passes through the first threaded groove and engages with one of the second threaded grooves.

[0020] By adopting the above technical solution, the bolt can selectively mate with different second thread grooves. This design allows for flexible adjustment of the position of the compression component within the compression chamber, thus adapting to airbags of different thicknesses or different compression requirements. Simultaneously, the bolt connection method is simple and reliable, facilitating assembly and disassembly, and improving the practicality and maintenance convenience of the plug structure.

[0021] Optionally, the outer wall of the compression component is provided with a guide block, and the inner wall of the opening is provided with a guide groove for the guide block to slide.

[0022] By adopting the above technical solution, the first thread groove and the second thread groove can be set up facing each other, thereby improving assembly efficiency.

[0023] Optionally, a sealing ring is integrally formed on one side of the sealing ring, and the sealing ring is used to abut against the inner wall of the aluminum roller.

[0024] By adopting the above technical solution, the sealing ring can increase or decrease the sealing effect of the sealing shell.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The sealing ring can tightly abut against the end of the aluminum roller to form a preliminary sealing effect; and the airbag is squeezed by the compression component to put the airbag into the second state. In this state, the airbag can increase the friction between the sealing shell and the inner wall of the aluminum roller, and the tightness between the airbag and the inner wall of the aluminum roller can increase the tensile strength of the sealing shell, thereby improving the stability of the sealing of the end of the aluminum roller; when the airbag is switched to the first state, the airbag is fully inserted into the compression chamber, which makes it easier to remove the sealing shell from the aluminum roller, avoiding the problem of difficulty in pulling out traditional rubber plugs due to interference fit, and improving the convenience of operation;

[0027] 2. The staggered arrangement of the end of the receiving groove and the end of the adjacent abutment groove can effectively increase the stability of the sealing shell fixed inside the aluminum roller, and the force is more evenly distributed, avoiding structural failure caused by stress concentration, thereby improving the sealing performance and connection reliability between the sealing shell and the inner wall of the aluminum roller.

[0033] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0034] Example 1:

[0035] This application discloses a plug structure for surface treatment of aluminum rollers.

[0036] Reference Figure 1 A plug structure for surface treatment of aluminum rollers includes a plugging housing 1, an air bladder 2, and a compression member 3. The outer wall of the plugging housing 1 is provided with a smooth coating 11, and the outer wall of the plugging housing 1 is adapted to the inner wall of the aluminum roller 6 so that the plugging housing 1 can be smoothly inserted into the aluminum roller 6 and the free shaking of the plugging housing 1 inside the aluminum roller 6 can be reduced.

[0037] A sealing ring 4 is provided on the outer wall of the sealing housing 1. The sealing ring 4 is used to abut against one end of the aluminum roller 6 to prevent the electrolyte solution from entering the interior of the aluminum roller 6 through the sealing housing 1 and the inner wall of the aluminum roller 6.

[0038] Reference Figure 2 The sealing housing 1 has a compression chamber 12 inside, and the airbag 2 is installed in the compression chamber 12. The outer wall of the sealing housing 1 has a plurality of abutment grooves 13 that are connected to the compression grooves. All abutment grooves 13 are spaced apart along the extension direction of the sealing housing 1, and one end of the abutment groove 13 is offset from the two adjacent abutment grooves 13. The compression component 3 is used to squeeze the airbag 2. When the airbag 2 is in the first state, the airbag 2 is in the compression chamber 12, so that the sealing housing 1 can be removed from the end of the aluminum roller 6. When the airbag 2 is in the second state, the outer wall of the airbag 2 passes through the abutment groove 13 and abuts against the inner wall of the aluminum roller 6.

[0039] A spring 21 is provided inside the airbag 2. The elastic force of the spring 21 is used to keep the airbag 2 in the first state so that the sealing shell 1 can be reused.

[0040] One end of the sealing housing 1 has an opening 14 that communicates with the compression chamber 12. The compression member 3 passes through the opening 14 and abuts against the airbag 2. The sealing housing 1 is fixed to the compression member 3 by a fixing component 5. In this embodiment, the fixing component 5 includes a first threaded portion 51 and a second threaded portion 52. The first threaded portion 51 is disposed on the outer wall of the compression member 3, and the second threaded portion 52 is disposed on the inner wall of the opening 14. The first threaded portion 51 and the second threaded portion 52 cooperate with each other.

[0041] The sealing housing 1 and the compression component 3 are fixedly connected by a threaded connection. This structural design allows the compression component 3 to be stably held in the designated position after squeezing the airbag 2, avoiding the compression component 3 from loosening due to external force and affecting the sealing effect.

[0042] In addition, the outer wall of the compressor 3 is provided with anti-slip grooves 31. The anti-slip grooves 31 can increase the friction between the operator's hand and the compressor 3, so as to facilitate the rotation of the compressor 3 and the airbag 2 to switch between the first state and the second state.

[0043] The implementation principle of Embodiment 1 of this application is as follows:

[0044] When the sealing housing 1 is inserted into the end of the aluminum roller 6, the sealing ring 4 can tightly abut against the end of the aluminum roller 6, forming a preliminary sealing effect. The airbag 2 is then squeezed by the compression component 3, causing the airbag 2 to partially extend from the compression chamber 12 and pass through the abutment groove 13, abutting against the inner wall of the aluminum roller 6. At this time, the airbag 2 is in the second state. In this state, the airbag 2 can increase the friction between the sealing housing 1 and the inner wall of the aluminum roller 6, and the tight abutment between the airbag 2 and the inner wall of the aluminum roller 6 can increase the pull-out resistance of the sealing housing 1, thereby improving the stability of the sealing of the end of the aluminum roller 6.

[0045] When the airbag 2 is switched to the first state, the airbag 2 is fully inserted into the compression chamber 12, which makes it easier to remove the sealing shell 1 from the aluminum roller 6. This avoids the problem of traditional rubber plugs being difficult to pull out due to interference fit, and improves the convenience of operation.

[0046] Example 2:

[0047] This application discloses a plug structure for surface treatment of aluminum rollers.

[0048] Reference Figure 3 The difference between Embodiment 2 and Embodiment 1 is that the compression assembly includes a bolt 53, the outer wall of the sealing housing 1 is provided with a first threaded groove 15 that communicates with the opening 14, the outer wall of the compression component 3 is provided with a plurality of second threaded grooves 32 that are directly opposite to the first threaded groove 15, and the bolt 53 passes through the first threaded groove 15 and cooperates with the second threaded grooves 32.

[0049] The outer wall of the compression component 3 is provided with a guide block 33, and the inner wall of the opening 14 is provided with a guide groove 16 for the guide block 33 to slide. The guide block 33 and the guide groove 16 are arranged so that the first thread groove 15 and the second thread groove 32 are aligned, thereby improving the installation efficiency.

[0050] The implementation principle of Embodiment 2 of this application is as follows:

[0051] The engagement of the first threaded groove 15 and the second threaded groove 32 can fix the compression component 3 and the sealing housing 1 together; and the bolt 53 can selectively engage with different second threaded grooves 32. This design allows the position of the compression component 3 in the compression chamber 12 to be flexibly adjusted to adapt to airbags 2 of different thicknesses or different compression requirements.

[0052] Example 3:

[0053] This application discloses a plug structure for surface treatment of aluminum rollers.

[0054] Reference Figure 4 The difference between Embodiment 3 and Embodiment 1 is that: a sealing ring 41 is integrally formed on the side of the sealing ring 4 near the opening 14, and the sealing ring 41 is inserted into the inner wall of the aluminum roller 6; this can reduce the situation where the electrolyte solution flows into the interior of the aluminum roller 6 through the gap between the sealing ring 4 and the end of the aluminum roller 6, and further improve the sealing effect on the end of the aluminum roller 6.

[0055] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
