[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figures 1 to 3 The high wear-resistant guide roller shown includes a roller component 1, a mounting component 4, and a roller shaft 5. The roller component 1 includes a roller body 11, a chromium nitride coating 12, and a diamond-like carbon film 13. The chromium nitride coating 12 is sprayed on the surface of the roller body 11, and the diamond-like carbon film 13 is disposed on the surface of the chromium nitride coating 12. Multiple sets of spiral reinforcing ribs 2 are fixedly connected to the inner wall of the roller body 11. Supporting circular plates 3 are fixedly connected to both ends of the roller body 11, and roller shafts 5 are provided at both ends of the roller body 11.

[0026] The roller body 11 and the roller shaft 5 are quickly assembled and disassembled using mounting parts 4. The roller body 11 is a thin-walled hollow tube made of high-hardness stainless steel. The spiral reinforcing rib 2 is spirally welded to the inner wall of the roller body 11. The supporting circular plate 3 is fixedly welded to the end position of the roller body 11. The spiral reinforcing rib 2 and the supporting circular plate 3 work together to improve the structural strength of the roller body 11.

[0027] The chromium nitride coating 12 is applied to the surface of the roller body 11 by melting powder with a plasma arc using atmospheric plasma spraying, and a diamond-like carbon film 13 is placed on the surface of the chromium nitride coating 12. The wear resistance of the roller body 11 surface is improved by the combination of the chromium nitride coating 12 and the diamond-like carbon film 13.

[0028] See Figure 1 , Figure 4 and Figure 5 The mounting component 4 is disposed between the roller component 1 and the roller shaft 5. The mounting component 4 includes a connecting plate 41, a connecting groove 42, a locking groove 43, a connecting seat 44, a positioning groove 45, a positioning block 46, an adjusting groove 47, an adjusting plate 48, a first limiting groove 49, a second limiting groove 410, a limiting rod 411, and a limiting spring 412. The connecting plate 41 is fixedly connected to the side of the supporting circular plate 3, and the connecting seat 44 is fixedly connected to one end of the inner side of the roller shaft 5.

[0029] In addition, during the process of connecting the roller shaft 5 and the roller component 1, the connecting seat 44 in the mounting component 4 is locked inside the connecting groove 42, and the positioning block 46 is locked inside the locking groove 43, thereby locking and fixing the roller component 1 and the roller shaft 5.

[0030] See Figures 4 to 6 A connecting groove 42 is formed on the surface of the connecting plate 41. Multiple sets of locking grooves 43 are formed on the inner walls of the front and rear sides of the connecting groove 42. Multiple sets of positioning grooves 45 are formed on both the front and rear ends of the connecting seat 44. The positioning block 46 is slidably connected to the interior of the positioning groove 45. An adjustment groove 47 is formed on the side wall of the positioning groove 45. The side of the adjustment plate 48 is slidably connected to multiple sets of adjustment grooves 47. The side of the adjustment plate 48 is fixedly connected to multiple sets of positioning blocks 46. A first limiting groove 49 and a second limiting groove 410 are formed on the inner end of the positioning block 46. The first limiting groove 49 and the second limiting groove 410 are stepped. The limiting rod 411 is slidably connected to the second limiting groove 410. The end of the limiting rod 411 located outside the second limiting groove 410 is fixedly connected to the inner wall of the positioning groove 45. The limiting spring 412 is sleeved on the surface of the limiting rod 411. The two ends of the limiting spring 412 abut against the side walls of the first limiting groove 49 and the positioning groove 45, respectively.

[0031] Specifically, during installation, the adjusting plates 48 on both sides of the connecting seat 44 are pressed inward simultaneously, thereby causing the positioning blocks 46 on both sides to slide into the positioning groove 45 simultaneously. After all the positioning blocks 46 are retracted into the positioning groove 45, the connecting seat 44 is inserted into the connecting groove 42. After the connecting seat 44 is fully inserted into the connecting groove 42, the adjusting plates 48 are released. At this time, multiple sets of limit springs 412 work together to push multiple sets of positioning blocks 46 outward simultaneously, locking the positioning blocks 46 into the locking groove 43, locking the connecting seat 44 and the connecting plate 41 together, thereby fixing the roller shaft 5 to the side of the roller component 1.

[0032] Meanwhile, when disassembling the roller shaft 5, the adjusting plates 48 on both sides of the connecting seat 44 are pressed inward simultaneously to retract the positioning block 46 into the positioning groove 45. Then, the connecting seat 44 is pulled out from the inside of the connecting groove 42 to complete the disassembly, thereby effectively improving the convenience of disassembling and assembling the roller shaft 5.

[0033] The working principle of this utility model is as follows: By setting a double-layer wear-resistant structure of chromium nitride coating 12 and diamond-like carbon film 13 on the surface of the roller body 11, the wear resistance of the roller body 11 is effectively improved, thereby increasing the service life of the roller and reducing production costs and maintenance time. At the same time, by inserting the connecting seat 44 into the connecting groove 42 and inserting multiple sets of positioning blocks 46 into the locking groove 43, the connecting seat 44 and the connecting groove 42 are quickly locked and fixed, improving the convenience of replacing the roller part 1, further reducing maintenance time and improving production efficiency.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
