Technical Field

[0001] This utility model relates to the field of roller sleeve technology, specifically a ceramic composite roller sleeve. Background Technology

[0002] The briquetting machine roller sleeve is an essential component in briquetting equipment. The roller sleeve determines the shape of the briquetting machine. The briquetting machine roller sleeve is a cylindrical component with briquetting holes dug into the surface of the outer layer of the briquetting machine roller core, and it is usually made of ceramic.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1 to 4As shown, in this embodiment, a ceramic composite roller sleeve includes a forming component 1 and an inner core 9. The forming component 1 is an annular plate structure formed by splicing multiple forming units 13. The forming unit 13 is an arc-shaped plate structure. The bottom of the multiple forming units 13 is fixedly connected to a limiting plate 11. The forming component 1 is slidably sleeved on the outer surface of the inner core 9. Multiple limiting grooves 10 are opened on the outer wall of the inner core 9. The multiple limiting grooves 10 are arranged in an annular array. The multiple limiting grooves 10 correspond one-to-one with the multiple limiting plates 11 and are adapted to each other. The two ends of the forming component 1 are provided with a shaping mechanism acting on the forming component 1. The two ends of the inner core 9 are provided with a fixing mechanism acting on the forming component 1.

[0021] The shaping mechanism includes an extension plate 12, a first annular sleeve 6, and a second annular sleeve 8. The two ends of multiple forming units 13 are respectively fixedly connected to the extension plate 12. The extension plate 12 is an arc-shaped plate. The width of the first annular sleeve 6 and the second annular sleeve 8 is equal to the length of the extension plate 12. The inner diameter of the first annular sleeve 6 and the second annular sleeve 8 is equal to the outer diameter of the extension plate 12. The inner diameter of the extension plate 12 is equal to the outer diameter of the inner core 9.

[0022] After multiple molding units 13 are spliced ​​together to form an annular plate structure, multiple extension plates 12 will also be spliced ​​together to form two annular plate structures, which are distributed on both sides of the molding component 1. The first annular sleeve 6 and the second annular sleeve 8 can be fitted onto the outer surface of the two annular plates formed by the extension plates 12, thereby shaping the molding component 1.

[0023] The fixing mechanism consists of a baffle 2, a pressure plate 3, a locking screw 4, and a nut 5. The baffle 2 is fixedly connected to one end of the inner core 9, and the pressure plate 3 is located at the other end of the inner core 9. The pressure plate 3 has multiple through holes 7, which traverse the inner core 9 and the baffle 2. The multiple through holes 7 are arranged in a ring array. The locking screw 4 is slidably inserted into the through holes 7, and the end of the locking screw 4 is threaded with a nut 5.

[0024] In use, after the forming component 1 is fitted onto the inner core 9, the baffle 2 can block one end of the forming component 1, then the pressure plate 3 is pressed against the other end of the forming component 1, and multiple locking screws 4 are passed through multiple through holes 7. The nuts of the locking screws 4 can press against the pressure plate 3, and the nuts 5 are tightened at the end of the locking screws 4 to complete the assembly of the roller sleeve.

[0025] This utility model provides a ceramic composite roller sleeve, the specific working principle of which is as follows:

[0026] In use, the second annular sleeve 8 is fitted onto the outer surface of the inner core 9. Then, multiple molding units 13 are placed over the outer surface of the inner core 9, so that the limiting plate 11 at the bottom of the molding unit 13 is engaged in the limiting groove 10 on the inner core 9. The engagement of the limiting groove 10 and the limiting plate 11 prevents the molding assembly 1 from rotating, and the extension plate 12 at one end of the molding unit 13 is engaged between the second annular sleeve 8 and the inner core 9. Then, the first annular sleeve 6 is fitted onto the outer surface of the extension plate 12 at the other end of the molding unit 13, and the pressure plate 3 abuts against the first annular sleeve 6 and the extension plate 12. Finally, multiple locking screws 4 are passed through multiple through holes 7, and the nuts of the locking screws 4 abut against the pressure plate 3. The nuts 5 are tightened at the end of the locking screws 4, thus completing the assembly of the roller sleeve. In this way, the molding unit 13 of the composite roller sleeve can be freely disassembled. When a certain part of the outer surface of the roller sleeve is severely worn, the molding unit 13 can be directly replaced without replacing the entire roller sleeve, thereby greatly reducing the maintenance cost of the roller sleeve.

[0027] 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.
