Description

Technical Field

[0001] The utility model belongs to the technical field of metal roller processing, in particular to a roller for coating a lithium ferrous phosphide high-temperature resistant phosphating film for metal. Background Art

[0002] Phosphating technology is a process of treating the metal surface with phosphating solution to form a uniform, fine, and corrosion-resistant phosphating film on its surface. In principle, it belongs to chemical conversion film technology, and phosphating is sometimes called chemical conversion film treatment. Phosphating treatment is often used in metal roller processing technology. Phosphating with phosphating solution forms a phosphating layer on the surface of the metal roller, thereby reducing the friction between the metal roller and the workpiece surface. However, the phosphating layer prepared by the phosphating solution will begin to decompose when the working temperature is higher than 200 degrees Celsius. In order to protect the metal roller, a metal lithium iron phosphide high-temperature phosphating film coating roller is usually used. In real life, when installing and using the metal lithium iron phosphide high-temperature phosphating film coating roller, most of them are installed with the roller frame inside the equipment, which is not convenient to disassemble directly. Once the metal roller is replaced, the roller frame needs to be disassembled before the metal roller can be taken out. The whole operation process is time-consuming and labor-intensive, reducing the convenience of replacement.

[0003] A Chinese patent document (application publication number CN209287985U) discloses a lithium iron phosphide high temperature resistant phosphating film coating roller for metal, which comprises a shaft head, a roller core, a sandblasting layer and a phosphating film layer, wherein the roller core body is provided with a sandblasting layer and a phosphating film layer; the thickness of the phosphating film layer is 0.3 mm to 0.9 mm.

[0004] It can be seen that the patent document cited above also has the same problem. Although it provides a high-temperature resistant phosphate film coating roller, it is not convenient to directly disassemble the coating roller after it is installed on the roller frame inside the equipment. Once the metal roller is replaced, the roller frame needs to be disassembled before the metal roller can be taken out. The whole operation process is time-consuming and labor-intensive, reducing the convenience of disassembly and replacement. Utility Model Content

The connecting rod 505 is connected to the first connecting block 504 and the second connecting block 506 by bearing connection. A clamping rod 508 is installed on the opposite side of 506, and the outer walls of the two clamping rods 508 are sleeved with a second spring 507. One end of the clamping rod 508 is clamped and connected with one side of the clamping block 2. Clamping holes are provided on both sides of the clamping block 2. The clamping rod 508 is clamped and connected with the clamping block 2 through the clamping holes. The first spring 502 cooperates with the second spring 507 to increase the stability between the clamping block 2 and the connecting roller shaft 3. When the elastic block 503 is located above the inner bottom end of the rod seat 4, the clamping rod 508 is separated from the clamping block 2.

[0032] The roller body 1 provided in this embodiment is composed of a metal roller core 101, a sandblasting layer 102 and a phosphating film layer 103, wherein the outer wall of the metal roller core 101 is sprayed with a sandblasting layer 102, and the outer wall of the sandblasting layer 102 is provided with a phosphating film layer 103, and the phosphating film layer 103 is a high-temperature resistant phosphating film of lithium iron phosphide, which is applied to the surface of the metal roller, which can not only reduce the friction between the metal roller and the surface of the workpiece and improve its service life, but also improve the high temperature resistance of the phosphating film.

[0033] In this embodiment, two connecting rollers 3 are provided with a clamping groove 301 on one side opposite to the other, and the inner sides of the two clamping grooves 301 are clamped and connected with the outer walls of the two clamping blocks 2 .

[0036] How it works

[0037] The connecting roller shaft 3 connected at both ends of the roller body 1 is connected and installed with the roller frame inside the equipment. When the metal roller needs to be replaced, the first connecting block 504 is pressed toward the rod seat 4. The first connecting block 504 moves through the moving rod 501 to squeeze the first spring 502. At the same time, the first connecting block 504 moves through the two connecting rods 505 to drive the two second connecting blocks 506 to move in the opposite direction. The second connecting block 506 moves to stretch the second spring 507 until the elastic block 503 moves to the inner wall of the rod seat 4. At this time, the clamping rod 508 is separated from the clamping block 2, and then the roller body 1 is moved to separate the clamping block from the connecting roller shaft 3. Similarly, after replacing a new metal roller, the elastic block 503 is pressed inwardly. Under the elastic action of the first spring 502 and the second spring 507, the clamping rod 508 is again engaged with the clamping blocks 2 at both ends of the roller body 1. In this way, the metal roller is conveniently replaced. When replacing the metal roller, the metal roller can be taken out without disassembling the roller frame. The whole operation process saves time and effort, and improves the convenience of replacement.
