Description

Technical Field

[0001] This utility model relates to the field of ceramic roller technology, and in particular to an insulating and wear-resistant ceramic coated roller. Background Technology

[0002] With the continuous development of industrial technology, higher requirements have been placed on the insulation and wear resistance of rollers. In order to improve the insulation and wear resistance of rollers, the industry usually adopts the method of spraying ceramic coating on the roller surface to make ceramic rollers. Ceramic coating has excellent insulation properties and can prevent current conduction. At the same time, its excellent wear resistance can reduce the wear of rollers during operation and extend the service life of rollers.

[0003] However, in the assembly process of ceramic coated rollers and roller shafts, cold pressing assembly is currently the most common method. Cold pressing assembly uses equipment such as presses to force the roller shaft into the inner hole of the roller by applying large pressure, thereby achieving the connection between the two. Although this assembly method is relatively simple to operate, the roller surface is subjected to huge mechanical pressure during the assembly process. Due to the high brittleness of the ceramic coating itself, it is very easy to crack or peel off when subjected to large compression or stress concentration. Once the ceramic coating is damaged, it will not only destroy the insulation performance of the roller, but also reduce the wear resistance of the roller and accelerate the wear of the roller. Therefore, we have introduced a new insulating and wear-resistant ceramic coated roller. Utility Model Content

[0004] The main objective of this invention is to provide an insulating and wear-resistant ceramic coating roller, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An insulating and wear-resistant ceramic-coated roller includes a roller shaft and a roller cylinder. The roller shaft has several first threaded holes on its upper left and lower left outer surfaces, as well as on its upper right and lower right outer surfaces. Mounting mechanisms are fixedly installed on the left and right outer surfaces of the roller shaft. The outer surface of the roller cylinder is coated with a ceramic coating. A through-hole is opened in the middle of the right end of the roller cylinder, through which the roller cylinder is inserted and connected to the roller shaft. Several positioning holes are opened on the inner side of the left end and the inner side of the right end of the roller cylinder. Four pressing mechanisms are rotatably connected to the outer side of the left end and the outer side of the right end of the roller cylinder.

[0007] Preferably, the mounting mechanism includes a connecting ring, with several positioning rods fixedly connected to the outer side of the right end of the connecting ring, and a mounting block fixedly connected to the middle of the left end of the connecting ring. A through hole is opened in the middle of the left end of the mounting block, so both the upper and lower parts of the outer surface of the mounting block are provided with cut surfaces. A second threaded hole is opened on both of the two cut surfaces, and an internal hexagon screw is threaded into both of the two second threaded holes.

[0008] Preferably, the right end of the connecting ring is in close contact with the roller, and the plurality of positioning rods are respectively inserted and engaged with the corresponding plurality of positioning holes.

[0009] By adopting the above technical solution, several positioning rods are inserted into the corresponding positioning holes, which allows the two connecting rings to fit against the side of the roller.

[0010] Preferably, both the connecting ring and the mounting block are located on the outside of the roller shaft, and the mounting block is movably connected to the roller shaft through a through hole.

[0011] Preferably, the ends of both hexagon socket screws extend into the through hole, and the ends of the two hexagon socket screws are respectively threaded into the corresponding first threaded hole.

[0012] By adopting the above technical solution, the assembly of the roller shaft and the roller can be achieved by screwing the internal hex screw into the corresponding first threaded hole.

[0013] Preferably, the pressing mechanism includes a connecting block, a pressing strip is fixedly connected to the lower part of the outer surface of the connecting block, a rotating rod is fixedly connected to the right end of the connecting block, and a damping rod is fixedly connected to the right end of the rotating rod.

[0014] Preferably, the right end of the pressure bar is in close contact with the left side of the connecting ring, the rotating rod is movably connected to the roller, and the damping rod is located inside the roller.

[0015] By adopting the above technical solution, the pressure strip fits against the side of the connecting ring, and the damping rod provides damping force inside the roller, providing additional axial positioning and fastening effect for the connecting ring, thereby enhancing the stability of the roller shaft and roller assembly.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By passing the roller shaft through the inner hole, the roller is positioned in the middle of the roller shaft. Then, the connecting ring and mounting block are inserted from the left and right sides of the roller shaft, and multiple positioning rods are inserted into the positioning holes on the left and right sides of the roller. The two connecting rings are pressed tightly against the side of the roller. Then, with the help of an Allen wrench, the two Allen screws on the top and bottom of the mounting block are screwed into the corresponding first threaded holes. This makes it easy and quick to assemble the roller shaft and the roller. Since there are multiple first threaded holes, it can be adapted to rollers of different lengths for installation. The entire installation process does not require applying mechanical pressure to the roller, avoiding damage such as cracking and peeling of the ceramic coating due to extrusion or stress concentration. This ensures the integrity of the ceramic coating, thereby maintaining the roller's good insulation and wear resistance and extending the roller's service life.

[0018] 2. After the roller is installed, the pressure bar is made to fit against the side of the connecting ring by rotating the rotating rod, and the damping rod provides damping force inside the roller, providing additional axial positioning and fastening effect for the connecting ring, and enhancing the stability of the roller shaft and roller assembly.

The left and right parts of the outer surface of the roller shaft 1 are fixedly installed with mounting mechanisms 4. The outer surface of the roller 2 is provided with a ceramic coating 5. The middle right end of the roller 2 is provided with a through hole 6. The roller 2 is inserted and connected to the roller shaft 1 through the through hole 6.

[0029] In this embodiment, the mounting mechanism 4 includes a connecting ring 41. Several positioning rods 42 are fixedly connected to the outer side of the right end of the connecting ring 41. A mounting block 43 is fixedly connected to the middle of the left end of the connecting ring 41. A through hole 44 is opened in the middle of the left end of the mounting block 43. Therefore, the upper part and the lower part of the outer surface of the mounting block 43 are provided with a cut surface 45. A second threaded hole 46 is opened on both cut surfaces 45. An internal hexagon screw 47 is threaded into both second threaded holes 46. The right end of the connecting ring 41 is in close contact with the roller 2. Several positioning rods 42 are respectively inserted and engaged with several corresponding positioning holes 7. The connecting ring 41 and the mounting block 43 are both located outside the roller shaft 1. The mounting block 43 is movably connected to the roller shaft 1 through the through hole 44. The ends of the two internal hexagon screws 47 extend into the through hole 44, and the ends of the two internal hexagon screws 47 are respectively threaded into the corresponding first threaded hole 3.

[0030] The above scheme involves passing the roller shaft 1 through the inner hole 6, positioning the roller 2 in the middle of the roller shaft 1, then inserting the connecting ring 41 and the mounting block 43 from the left and right sides of the roller shaft 1, allowing multiple positioning rods 42 to be inserted into the positioning holes 7 on the left and right sides of the roller 2, ensuring that the two connecting rings 41 are tightly against the sides of the roller 2, and then using an Allen wrench to screw the two Allen screws 47 on the upper and lower parts of the mounting block 43 into the corresponding first threaded holes 3. This allows for convenient and quick assembly of the roller shaft 1 and the roller 2, and since there are multiple first threaded holes 3, they can be adapted to install rollers 2 of different lengths.
