Description

Technical Field

[0001] This application relates to the field of rust prevention technology for mounting shafts, specifically a rust prevention structure for aluminum guide roller mounting shafts. 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] Aluminum guide rollers are usually fixed with metal mounting shafts (generally made of high-hardness alloys) at both ends. To prevent the mounting shafts from rusting, anti-rust oil is applied to them. However, the anti-rust oil can easily get on the surface of the aluminum guide rollers, causing corrosion and affecting their performance. To solve this problem, an anti-rust structure for the mounting shafts of aluminum guide rollers is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a rust-proof structure for the mounting shaft of an aluminum guide roller. It utilizes a plastic wrap to isolate the air and a desiccant to absorb any trace amounts of moisture that may enter, thus preventing the mounting shaft from rusting and also preventing the aluminum roller from being contaminated with rust-preventive oil.

[0005] To achieve the above objectives, this application provides the following technical solution: an anti-rust structure for an aluminum guide roller mounting shaft, comprising an aluminum guide roller body, a mounting shaft body, and a connecting mechanism. The mounting shaft body is provided with an anti-rust mechanism on its exterior. The anti-rust mechanism includes four grooves formed on the outer surface of the mounting shaft body. The outer surface of the mounting shaft body and the inner walls of the four grooves are coated with an anti-rust coating. The inner wall of the anti-rust coating is filled with four desiccants. A connecting hole is formed at one end of the mounting shaft body. A second rubber plug is provided on the inner wall of the connecting hole. A plastic wrap is wrapped around the exterior of the anti-rust coating. The four desiccants and the second rubber plug are located between the plastic wrap and the anti-rust coating.

[0006] The above solution allows for convenient assembly and disassembly of the mounting shaft body and the aluminum guide roller body via a connecting mechanism, facilitating the replacement of damaged aluminum guide roller bodies or mounting shaft bodies. The anti-rust mechanism prevents rusting of the mounting shaft body. The grooves do not affect the normal operation of the mounting shaft body and also allow for easy placement of desiccant. The anti-rust coating provides long-lasting rust protection, and the added plastic wrap provides physical isolation, resulting in superior rust prevention through double protection. The desiccant filled between the anti-rust coating and the plastic wrap absorbs any trace moisture that may enter, further enhancing the rust prevention effect of the mounting shaft body.

[0007] Furthermore, the connecting mechanism includes sealing rings fixedly connected to both ends of the aluminum guide roller body, and rectangular grooves are provided at both ends of the aluminum guide roller body.

[0008] The above method allows for a more stable installation of the mounting shaft body at both ends of the aluminum guide roller body.

[0009] Furthermore, a first rubber pad is fixedly connected to the inner wall of each rectangular groove, and a second rubber pad is fixedly connected to both ends of the aluminum guide roller body. The sealing ring is located between the rectangular groove and the second rubber pad.

[0010] The above solution, by setting the first and second rubber pads, can reduce the chance of rust at both ends of the aluminum guide roller body and extend the service life of the aluminum guide roller body.

[0011] Furthermore, multiple first through holes are provided at both ends of the aluminum guide roller body and on the surfaces of the two second rubber pads, and a number of second through holes corresponding to the number of first through holes are provided at one end of the mounting shaft body.

[0012] The above scheme facilitates the subsequent installation of the aluminum guide roller body and the mounting shaft body through the first and second through holes.

[0013] Furthermore, a connecting bolt is installed on the inner wall of each of the second through holes, the size of which corresponds to the size of the first through hole, and a first rubber plug is provided inside each of the second through holes.

[0014] With the above solution, when the connecting bolt on the inner wall of the second through hole is screwed into the first through hole, the mounting shaft body can be positioned and installed at one end of the aluminum guide roller body. The first rubber plug can reduce the chance of the second through hole rusting.

[0015] Furthermore, a sealing groove is provided at one end of the mounting shaft body, and the size of the sealing groove corresponds to the size of the sealing ring.

[0016] The above solution allows the sealing ring to be inserted into the sealing groove, improving the sealing performance of the connection between the aluminum guide roller body and the mounting shaft body.

[0017] Furthermore, a rectangular block is fixedly connected to one end of the mounting shaft body, and the dimensions of the rectangular block are adapted to the dimensions of the rectangular groove and the first rubber pad.

[0018] The above scheme, by setting rectangular blocks, can make the connection between the mounting shaft body and the aluminum guide roller body more stable.

[0019] Furthermore, the mounting shaft body is mounted on one end of the aluminum guide roller body via a connecting mechanism.

[0020] The above solution allows for easy assembly and disassembly of the mounting shaft body onto the aluminum guide roller body via a connecting mechanism, facilitating the replacement of damaged aluminum guide roller bodies or mounting shaft bodies, thus making the device more practical.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This rust-proof structure for an aluminum guide roller mounting shaft allows for easy assembly and disassembly of the mounting shaft body and the aluminum guide roller body via a connecting mechanism. This facilitates the replacement of damaged aluminum guide roller bodies or mounting shaft bodies. The first rubber pad, second rubber pad, and first rubber plug work together to reduce the likelihood of rust on the aluminum guide roller body. The rust-proof mechanism prevents rust on the mounting shaft body. The grooves do not affect the normal operation of the mounting shaft body and also allow for convenient placement of desiccant. The rust-proof coating provides long-lasting rust protection for the mounting shaft body. Combined with a protective film, this provides physical isolation for the mounting shaft body. This double protection results in superior rust prevention. The desiccant filled between the rust-proof coating and the protective film absorbs any trace moisture that may enter, further enhancing the rust-proof effect of the mounting shaft body.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 3 and Figure 4 This embodiment of an aluminum guide roller mounting shaft anti-rust structure includes an aluminum guide roller body 1, a mounting shaft body 2, and a connecting mechanism 3. The mounting shaft body 2 is mounted on one end of the aluminum guide roller body 1 via the connecting mechanism 3. The connecting mechanism 3 allows for easy assembly and disassembly of the mounting shaft body 2 on the aluminum guide roller body 1, facilitating the replacement of damaged aluminum guide roller body 1 or mounting shaft body 2, making the device more practical. The connecting mechanism 3 includes sealing rings 301 fixedly connected to both ends of the aluminum guide roller body 1. A sealing groove 309 is provided at one end of the mounting shaft body 2, and the dimensions of the sealing groove 309 correspond to the dimensions of the sealing rings 301. The sealing rings 301 can be inserted into the sealing groove 309 through the sealing groove 309. In section 9, the sealing performance of the connection between the aluminum guide roller body 1 and the mounting shaft body 2 is improved, thereby reducing the probability of rust at the connection between the aluminum guide roller body 1 and the mounting shaft body 2. Rectangular grooves 302 are provided at both ends of the aluminum guide roller body 1. The mounting shaft body 2 can be installed more stably at both ends of the aluminum guide roller body 1 through the rectangular grooves 302. A first rubber pad 303 is fixedly connected to the inner wall of each rectangular groove 302. A rectangular block 310 is fixedly connected to one end of the mounting shaft body 2. The size of the rectangular block 310 is adapted to the size of the rectangular groove 302 and the first rubber pad 303. Inserting the rectangular block 310 into the rectangular groove 302 and the first rubber pad 303 can make the connection between the mounting shaft body 2 and the aluminum guide roller body 1 more stable.

[0032] Please see Figure 2 , Figure 3 and Figure 4 Both ends of the aluminum guide roller body 1 are fixedly connected with second rubber pads 304. A sealing ring 301 is located between the rectangular groove 302 and the second rubber pad 304. The first rubber pad 303 and the second rubber pad 304 improve the sealing effect at the connection between the aluminum guide roller body 1 and the mounting shaft body 2, thereby reducing the probability of rust at both ends of the aluminum guide roller body 1 and extending its service life. Multiple first through holes 305 are provided at both ends of the aluminum guide roller body 1 and on the surface of the two second rubber pads 304. One end of the mounting shaft body 2 is provided with a number of second through holes 306 corresponding to the number of first through holes 305. The sealing ring 306 is connected to the first through holes 305 and the second rubber pad 304. The second through hole 306 facilitates the subsequent installation of the aluminum guide roller body 1 and the mounting shaft body 2. Each second through hole 306 has a connecting bolt 307 installed on its inner wall. The size of the connecting bolt 307 corresponds to the size of the first through hole 305. Each second through hole 306 has a first rubber plug 308 inside. When the connecting bolt 307 on the inner wall of the second through hole 306 is turned so that the connecting bolt 307 is screwed into the first through hole 305, the mounting shaft body 2 can be positioned and installed at one end of the aluminum guide roller body 1. The first rubber plug 308 can reduce the chance of rust in the second through hole 306 and optimize the rust prevention effect of the device.

[0033] Please see Figure 1 , Figure 4 and Figure 5The mounting shaft body 2 is equipped with a rust-proof mechanism 4 on its exterior. The rust-proof mechanism 4 includes four grooves 401 formed on the outer surface of the mounting shaft body 2. Both the outer surface of the mounting shaft body 2 and the inner walls of the four grooves 401 are coated with an rust-proof coating 402. This rust-proof coating 402 provides long-lasting rust protection for the mounting shaft body 2. The inner walls of the rust-proof coating 402 are filled with four desiccants 403, which are located inside the four grooves 401. The grooves 401 allow for convenient filling of the desiccants 403 without affecting the normal use of the mounting shaft body 2, making the structure of the device more compact. The filled desiccants 403 can absorb trace amounts of moisture that may enter the surface of the mounting shaft body 2, thereby improving the rust-proof effect of the mounting shaft body 2. A connecting hole 404 is provided at one end of the mounting shaft body 2. The connection hole 404 facilitates the connection of the device with other components during use. The inner wall of the connection hole 404 is provided with a second rubber plug 405, which reduces the chance of rust on the inner wall of the connection hole 404. The rust-proof coating 402 is wrapped with a plastic wrap 406. Four desiccants 403 and a second rubber plug 405 are located between the plastic wrap 406 and the rust-proof coating 402. The plastic wrap 406 can isolate air and moisture, providing physical protection for the mounting shaft body 2. The desiccants 403 and the second rubber plug 405 are both located between the plastic wrap 406 and the rust-proof coating 402. In this way, the plastic wrap 406, the rust-proof coating 402, the desiccants 403 and the second rubber plug 405 work together to provide multiple rust-proof effects for the mounting shaft body 2, effectively preventing the mounting shaft body 2 from rusting.

[0034] It should be noted that the rust-proof mechanism 4 is mainly designed to protect the mounting shaft body 2 from rusting during storage or non-working conditions. The function of the plastic wrap 406 is to prevent the mounting shaft body 2 from rusting due to exposure to a humid environment during storage by isolating it from air and moisture. This design is particularly suitable for rust protection of the mounting shaft body 2 during transportation, warehousing, or long-term idle periods. Furthermore, by using the rust-proof coating 402 instead of rust-proof oil, the rust-proof oil on the aluminum guide roller body 1 can be prevented from adhering to the aluminum guide roller body 1 at the source. If rust-proof oil is applied to the mounting shaft body 2, the plastic wrap 406 can also prevent the rust-proof oil from adhering to the aluminum guide roller body 1, thereby reducing the likelihood of rust on the surface of the aluminum guide roller body 1 and making it more practical.

[0035] In this embodiment, an anti-rust structure for an aluminum guide roller mounting shaft allows for convenient assembly and disassembly of the mounting shaft body 2 and the aluminum guide roller body 1 via a connecting mechanism 3. This facilitates the replacement of damaged aluminum guide roller body 1 or mounting shaft body 2. The first rubber pad 303, the second rubber pad 304, and the first rubber plug 308 work together to reduce the likelihood of rust on the aluminum guide roller body 1. The anti-rust mechanism 4 prevents rust on the mounting shaft body 2. The groove 401 does not affect the normal operation of the mounting shaft body 2 and allows for convenient placement of a desiccant 403. The anti-rust coating 402 provides long-lasting anti-rust performance for the mounting shaft body 2. Combined with a plastic wrap 406, this provides physical isolation for the mounting shaft body 2. This double protection enhances the anti-rust effect of the mounting shaft body 2. The desiccant 403, filled between the anti-rust coating 402 and the plastic wrap 406, absorbs any trace moisture that may enter, further improving the anti-rust effect of the mounting shaft body 2.

[0036] The working principle of the above embodiment is as follows: First, a rust-preventive coating 402 is applied to the outer surface of the mounting shaft body 2 and the inner walls of the four grooves 401. After drying, four desiccants 403 are filled into the four grooves 401 respectively. Then, the second rubber plug 405 is inserted into the connection hole 404. Next, a plastic wrap 406 is wrapped around the rust-preventive coating 402, the desiccant 403, and the second rubber plug 405. In this way, the plastic wrap 406 provides physical protection for the mounting shaft body 2, isolating it from air and moisture, while the desiccant 403 absorbs the rust-preventive coating 402 and the plastic wrap. The residual moisture between the membranes 406 further optimizes the rust prevention effect on the mounting shaft body 2. At the same time, the rust-proof coating 402 provides long-term rust protection for the mounting shaft body 2. Therefore, the rust-proof mechanism 4 provides multiple rust protection for the mounting shaft body 2. If the aluminum guide roller body 1 or the mounting shaft body 2 is damaged, multiple first rubber plugs 308 can be removed from the second through hole 306, then multiple connecting bolts 307 can be unscrewed, and finally the mounting shaft body 2 can be removed from one end of the aluminum guide roller body 1. Then the replaced components can be connected through the connecting mechanism 3.
