Description

Technical Field

[0001] This utility model belongs to the field of transmission roller technology, and specifically relates to a corrosion-resistant transmission roller. Background Technology

[0002] In the fields of metallurgy and heat treatment, it is often necessary to transport metal materials or parts in high-temperature environments, and drive rollers are generally used. Existing drive rollers consist of a roller body, roller necks, and shaft ends. The roller necks are welded to the shaft ends, and the two ends of the roller body are welded to the two roller necks.

[0003] Currently, corrosion-resistant drive rollers typically have a fixed connection between the corrosion-resistant layer and the drive roller during use. This design has the following drawbacks over long-term use: First, maintenance costs are high. When the corrosion-resistant layer is partially damaged due to corrosion or wear, even if the substrate is intact, the entire roller must be replaced, resulting in a significant waste of undamaged substrate material. Second, adaptability is poor. The roller cannot flexibly replace the appropriate corrosion-resistant working layer according to changes in the corrosive environment (such as media concentration and temperature fluctuations). This leads to either frequent failures due to insufficient corrosion protection or cost waste due to excessive corrosion protection. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a corrosion-resistant transmission roller. This addresses the drawbacks of existing technologies where the corrosion-resistant layer and transmission roller are fixedly connected, leading to several issues over long-term use. Firstly, maintenance costs are high. When the corrosion-resistant layer suffers localized damage due to corrosion or wear, even if the substrate remains intact, the entire roller must be replaced, resulting in a significant waste of undamaged substrate material. Secondly, adaptability is poor. The roller cannot flexibly adapt to changes in the corrosive environment (such as medium concentration or temperature fluctuations), leading to either frequent failures due to insufficient corrosion protection or costly waste due to excessive corrosion protection.

[0006] (2) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides a corrosion-resistant transmission roller, including a transmission roller base, a portable replacement mechanism is installed around the periphery of the transmission roller base, the portable replacement mechanism includes a corrosion-resistant mother cylinder, which is sleeved on a section of the periphery of the transmission roller base, and a corrosion-resistant daughter cylinder is sleeved on the other section of the periphery of the transmission roller base. A first assembly component is installed at the connection between the corrosion-resistant mother cylinder and the corrosion-resistant daughter cylinder, and a second assembly component is provided between the corrosion-resistant mother cylinder and the corrosion-resistant daughter cylinder and the mounting part of the transmission roller base.

[0008] Furthermore, the first assembly component includes insert blocks, which are disposed at the annular inner end of the corrosion-resistant sub-cylinder. The inner end of the corrosion-resistant main cylinder is provided with slots. The ends of the plurality of insert blocks are provided with first threaded grooves. A second threaded groove is provided at the opposite periphery of a section of the transmission roller base. A first locking screw is screwed into the middle of the second threaded groove. A preset annular groove is provided around the inner end of the corrosion-resistant main cylinder. A sealing gasket is provided inside the preset annular groove. An embedded annular block is fixed around the inner end of the corrosion-resistant sub-cylinder.

[0009] Furthermore, the first threaded groove of the insert block and the second threaded groove opposite to the anti-corrosion mother cylinder are both connected by a first locking screw to form a threaded locking connection, and a rubber sealing ring is sleeved around the inner end of the first locking screw.

[0010] Furthermore, the anti-corrosion mother cylinder and the anti-corrosion daughter cylinder are respectively aligned and fitted around the two sides of the transmission roller base, and the preset annular groove at the inner end of the anti-corrosion mother cylinder and the embedded annular block at the inner end of the anti-corrosion daughter cylinder are fitted together in a fitting manner.

[0011] Furthermore, the second assembly includes a fixing ring block, which is disposed around the two sides of the shaft of the transmission roller base. A sealing ring gasket is provided on the outer side of the fixing ring block, and a third threaded groove is provided around the periphery of the fixing ring block. A fourth threaded groove is provided around the opposite ends of the anti-corrosion mother cylinder and the anti-corrosion daughter cylinder, and a second locking screw is screwed into the middle of the fourth threaded groove.

[0012] Furthermore, in the installed state, the sealing ring gaskets are located on the opposite sides of the anti-corrosion mother cylinder and the anti-corrosion daughter cylinder, and the anti-corrosion mother cylinder, the anti-corrosion daughter cylinder and the corresponding sealing ring gaskets are all connected by threads using the separately provided third thread groove, fourth thread groove, second locking screw and fixed ring block provided on the transmission roller base.

[0013] (3) Beneficial effects

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

[0015] When installing an anti-corrosion mother cylinder and an anti-corrosion daughter cylinder on the transmission roller base to achieve the anti-corrosion effect, the operator needs to pre-install both cylinders onto the left and right halves of the transmission roller base. During installation, multiple inserts at the inner end of the anti-corrosion daughter cylinder must be precisely aligned and inserted into the corresponding slots at the inner end of the anti-corrosion mother cylinder until the first threaded groove at the end of the inserts partially overlaps with the second threaded groove at the corresponding position of the anti-corrosion mother cylinder. At this point, the operator can integrate and fix the anti-corrosion mother cylinder and the anti-corrosion daughter cylinder using the first locking screw. In this state, the preset annular groove, sealing gasket, and embedded ring block at the joint of the two cylinders can effectively achieve a seal. Subsequently, according to the fourth threaded groove at the opposite end of the anti-corrosion mother cylinder and the anti-corrosion daughter cylinder, the corresponding transmission roller base is then installed. The third threaded groove on the two fixed ring blocks of the moving roller base is inserted into the second locking screw for fixation. The inner end faces of multiple second locking screws are pressed against the sealing ring gasket to ensure the structural stability and sealing between the anti-corrosion mother cylinder, the anti-corrosion daughter cylinder and the drive roller base, and to prevent misalignment between the anti-corrosion sleeve and the base during subsequent use. This completes the installation of the anti-corrosion working surface and the base. When it is necessary to replace the anti-corrosion module with a different material according to the type of medium, for example, replacing the Hastelloy material sleeve for strong acid environments such as electroplating and pickling, or replacing the polymer material sleeve for low corrosion and self-cleaning scenarios such as papermaking and printing and dyeing, the corresponding replacement can be completed by operating in the same way as above.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This specific embodiment is a corrosion-resistant transmission roller, and its structural schematic diagram is shown below. Figures 1 to 4As shown, the device includes a drive roller base 1, with a portable replacement mechanism 2 mounted around its periphery. The portable replacement mechanism 2 includes a corrosion-resistant female sleeve 21, which is fitted around one section of the drive roller base 1. A corrosion-resistant female sleeve 22 is fitted around the other section of the drive roller base 1. A first assembly assembly 23 is installed at the connection between the corrosion-resistant female sleeve 21 and the corrosion-resistant female sleeve 22. The first assembly assembly 23 includes inserts 231, which are distributed at the annular inner end of the corrosion-resistant female sleeve 22. The inner end of the corrosion-resistant female sleeve 21 has slots 232. First threaded grooves 233 are formed at the ends of multiple inserts 231. Second threaded grooves 234 are formed at opposite locations on the periphery of one section of the drive roller base 1, and a first locking mechanism is screwed into the center of the second threaded grooves 234. The screw 235 and the insert 231 have a first threaded groove 233 and a second threaded groove 234 opposite to the anti-corrosion mother cylinder 21, respectively, forming a threaded locking connection using the first locking screw 235. A rubber sealing ring is fitted around the inner end of the first locking screw 235. A pre-set annular groove 236 is formed around the inner end of the anti-corrosion mother cylinder 21, and a sealing gasket 237 is provided inside the pre-set annular groove 236. An embedded ring block 238 is fixed around the inner end of the anti-corrosion daughter cylinder 22. The anti-corrosion mother cylinder 21 and the anti-corrosion daughter cylinder 22 are respectively aligned and fitted around the two sides of the transmission roller base 1. The pre-set annular groove 236 at the inner end of the anti-corrosion mother cylinder 21 and the embedded ring block 238 at the inner end of the anti-corrosion daughter cylinder 22 are fitted together in a wedge-shaped connection. The anti-corrosion mother cylinder 21 and the anti-corrosion daughter cylinder 22 are connected in a wedge-shaped connection. The sub-cylinder 22 is respectively provided with a second assembly 24 on the mounting part of the transmission roller base 1. The second assembly 24 includes a fixing ring block 241, which is respectively disposed around the two sides of the shaft of the transmission roller base 1. A sealing ring gasket 242 is provided on the outer side of the fixing ring block 241, and a third threaded groove 243 is provided around the periphery of the fixing ring block 241. A fourth threaded groove 244 is provided around the opposite ends of the anti-corrosion mother cylinder 21 and the anti-corrosion sub-cylinder 22, and a second locking screw 245 is screwed into the middle of the fourth threaded groove 244. The sealing ring gasket 242 is located outside the opposite ends of the anti-corrosion mother cylinder 21 and the anti-corrosion sub-cylinder 22 in the installed state. The anti-corrosion mother cylinder 21, the anti-corrosion sub-cylinder 22 and the corresponding sealing ring gasket 242 are all provided with the third threaded groove 243. The threaded groove 243, the fourth threaded groove 244, the second locking screw 245, and the fixing ring block 241 provided on the transmission roller base 1 form a threaded fixed connection. When installing the anti-corrosion mother cylinder 21 and the anti-corrosion daughter cylinder 22 on the transmission roller base 1 to achieve the anti-corrosion effect, the personnel need to pre-fit the two cylinders onto the left and right halves of the transmission roller base 1 respectively. During the installation process, the multiple inserts 231 at the inner end of the anti-corrosion daughter cylinder 22 need to be precisely aligned and inserted into the corresponding slots 232 at the inner end of the anti-corrosion mother cylinder 21 until the first threaded groove 233 at the end of the insert 231 partially overlaps with the second threaded groove 234 at the corresponding position of the anti-corrosion mother cylinder 21. At this time, the personnel can integrate and fix the anti-corrosion mother cylinder 21 and the anti-corrosion daughter cylinder 22 through the first locking screw 235. In this state,The pre-set annular groove 236, sealing gasket 237, and embedded ring block 238 at the junction of the two effectively achieve sealing. Subsequently, according to the fourth threaded groove 244 at the opposite ends of the anti-corrosion mother cylinder 21 and the anti-corrosion daughter cylinder 22, corresponding to the third threaded groove 243 on the two fixed ring blocks 241 of the transmission roller base 1, the second locking screw 245 is inserted for fixation. The inner end faces of the multiple second locking screws 245 are pressed against and tighten the sealing ring gasket 242, thereby ensuring the structural stability and sealing between the anti-corrosion mother cylinder 21, the anti-corrosion daughter cylinder 22, and the transmission roller base 1, and preventing misalignment between the anti-corrosion sleeve and the base during subsequent use, thus completing the installation of the anti-corrosion working surface and the base. When it is necessary to replace the anti-corrosion module with a different material according to the type of medium, for example, replacing the Hastelloy material sleeve for strong acid environments such as electroplating and pickling, or replacing the polymer material sleeve for low-corrosion and self-cleaning scenarios such as papermaking and printing and dyeing, the corresponding replacement can be completed by operating in the same way as above.

[0024] Working principle: When installing the anti-corrosion mother cylinder 21 and anti-corrosion daughter cylinder 22 on the transmission roller base 1 to achieve the anti-corrosion effect, the personnel need to pre-install the two cylinders on the left and right halves of the transmission roller base 1 respectively. During the installation process, the multiple inserts 231 at the inner end of the anti-corrosion daughter cylinder 22 need to be precisely aligned and inserted into the corresponding slots 232 at the inner end of the anti-corrosion mother cylinder 21 until the first threaded groove 233 at the end of the insert 231 partially overlaps with the second threaded groove 234 at the corresponding position of the anti-corrosion mother cylinder 21. At this time, the personnel can integrate and fix the anti-corrosion mother cylinder 21 and the anti-corrosion daughter cylinder 22 through the first locking screw 235. In this state, the preset annular groove 236, sealing gasket 237 and embedded ring block 238 at the joint of the two can effectively achieve sealing. Subsequently, according to the relative positions of the anti-corrosion mother cylinder 21 and the anti-corrosion daughter cylinder 22... The fourth threaded groove 244 at the end corresponds to the third threaded groove 243 on the two fixed ring blocks 241 of the transmission roller base 1. The second locking screw 245 is inserted for fixation. The inner end faces of the multiple second locking screws 245 are pressed against the sealing ring gasket 242 to ensure the structural stability and sealing between the anti-corrosion mother cylinder 21, the anti-corrosion daughter cylinder 22 and the transmission roller base 1, and to prevent the anti-corrosion sleeve from misaligning with the base during subsequent use. This completes the installation of the anti-corrosion working surface and the base. When it is necessary to replace the anti-corrosion module with a different material according to the type of medium, for example, replacing the Hastelloy material sleeve for strong acid environments such as electroplating and pickling, or replacing the polymer material sleeve for low corrosion and self-cleaning scenarios such as papermaking and printing and dyeing, the corresponding replacement can be completed by operating in the same way as above.

[0025] All technical features in this embodiment can be freely combined according to actual needs.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
