Description

Technical Field

[0001] The utility model relates to the technical field of cooling rollers, in particular to a cooling roller with a replaceable roller. Background Art

[0002] The tablet press is a common device for powder coating production. It is mainly used to cool and extrude the material into flakes. This is convenient for later crushing. Since the extruded high-temperature powder coating has a certain viscosity, the surface of the roller is required to be smooth. At the same time, the surface of the roller can be cooled quickly. This allows the material to cool down quickly and avoid adhesion to the roller. This causes the material to roll back and damage the roller.

[0003] During daily production, some metal materials or tools may fall into the rollers. The surface of the rollers will be damaged. At the same time, the cooling water in the rollers will scale due to high temperatures, which will reduce the cooling efficiency. In severe cases, the rollers will stick. When these problems occur, the rollers often need to be replaced. Since the rollers are currently integrated, the rollers are also parts that need to be replaced frequently on the tablet press. This also brings greater cost expenditures to the company. Utility Model Content

[0022] The technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Embodiment 1:

[0024] See also Figure 1-3 As shown, the utility model provides a cooling roller with replaceable rollers, which is characterized in that the roller 200 can be disassembled from the roller 100. During long-term use, if the surface of the roller (roller 200) is damaged, the roller 200 can be disassembled and replaced, and the replaced roller 200 can be scrapped or repaired according to the degree of wear; if thick scale is generated inside the roller 200, resulting in poor cooling effect, the roller 200 can also be disassembled from the roller 100 for scale cleaning and maintenance.

[0025] In the embodiment of the present disclosure, the roller-replaceable cooling roller comprises a roller 100, a roller 200, a mounting plate 300 and a nut 400. The roller 100 comprises a main body 101 and a water flow channel 102. The two ends of the main body 101 are coaxially provided with mounting sections 103. The end of the mounting section 103 away from the main body 101 is provided with a threaded section 104. The end of the threaded section 104 away from the mounting section 103 is provided with a support section 105. The water flow channel 102 extends from the support section 105 and is connected to the end of the main body 101 and then penetrates the main body 101. The water flow channels 102 respectively provided at the two ends of the main body 101 are not connected to each other; the two ends of the roller 200 are not closed, and the ends of the two ends of the roller 200 are provided with embedded grooves 201; the mounting plate 300 is annular, with a mounting hole 301 in the middle and an embedded block 302 on the outside.

[0026] During assembly, the roller 200 is coaxially inserted on the roller 100, and a mounting plate 300 is respectively set at both ends of the roller 100. The mounting hole 301 is inserted on the mounting section 103, the outer side of the mounting plate 300 is embedded in the inner side of the roller 200, the insert 302 is embedded in the insert groove 201, and the nut 400 is set on the threaded section 104 and abuts against the mounting plate 300. The roller 100 and the roller 200 are supported by the mounting plate 300, and then the nut 400 is matched to realize a detachable installation connection, which is convenient for assembly and operation, and has a good practical effect. During operation, cooling water can enter the roller 200 from one of the water flow channels 102 to cool the roller 200, and at the same time, it can flow out from the other water flow channel 102 to realize the circulation of cooling water. Among them, the cooperation between the insert groove 201 and the insert 302 can effectively prevent unnecessary sliding during the rotation of the roller 200 driven by the mounting plate 300.

[0027] Furthermore, an annular support platform 106 is provided on the inner side of both ends of the roller 200, and the support platform 106 supports the end surface of the mounting plate 300 to prevent the roller 200 from moving on the roller 100. At the same time, a first sealing ring 500 is provided between the mounting plate 300 and the support platform 106 for sealing.

[0028] Furthermore, in order to more effectively avoid the problem of stringing between the mounting plate 300 and the roller 100, the end surface of the main body 101 forms a support platform 106 between the mounting section 103 and the main body 101, and the support platform 106 supports the end surface of the mounting plate 300. At the same time, a limiting groove 107 is provided on the support platform 106, and a limiting protrusion 303 is provided on the mounting plate 300 and embedded in the limiting groove 107. The limiting groove 107 cooperates with the limiting protrusion 303 to avoid unnecessary sliding between the mounting plate 300 and the roller 100.

[0029] Furthermore, in order to ensure the sealing performance between the roller 100 and the mounting plate 300 , a second sealing ring 600 is disposed between the support platform 106 and the mounting plate 300 .

[0030] Embodiment 2:

[0031] like Figure 4 and Figure 5 As shown, the difference is that the outer diameter of the main body 101 matches the inner wall of the roller 200 , and a cooling water tank 108 is provided on the main body 101 surrounding the main body 101 .

[0032] There are two implementation methods of the cooling water tank 108. First, the cooling water tank 108 is in a straight line, such as Figure 5 A plurality of cooling water grooves 108 are distributed circumferentially on the outer circumference of the main body 101 .

[0033] Second, the cooling water tank 108 is spiral-shaped, such as Figure 4 The cooling water tank 108 starts from one end of the main body 101 and extends in a spiral shape along the outer circumference of the main body 101 to the other end of the main body 101 .

[0034] In this solution, the main body 101 can support the roller 200 during the process of extruding the material into sheets, thereby reducing the wall thickness of the roller 200. Firstly, it reduces the production cost of the roller 200, and secondly, it can improve the cooling efficiency of the roller 200.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
