If the roller operates at high temperature for a long time, it will cause slight deformation of the surface, which will affect the quality of other objects in the future. Utility Model Content

[0004] The purpose of the utility model is to provide a high-strength, wear-resistant and corrosion-resistant rolling roller to solve the problem proposed in the above background technology that high temperature will be generated when the rolling roller rotates and rubs against other objects. The rolling roller operates at high temperature for a long time, which will cause slight deformation of the surface and affect the quality of other objects in the later stage.

[0006] By adopting the above technical scheme, cold air or cold liquid flows along the inlet and outlet pipes, cooling pipes and connecting pipes, and the cold air is used to internally dissipate heat to the roller body, roller head and roller neck, so that the roller body, roller head and roller neck dissipate heat simultaneously from the inside and outside, thereby increasing the heat dissipation speed of the roller body, roller head and roller neck.

[0007] Preferably, a hollow reinforcement tube is provided inside the roller body, the roller head and the roller neck and close to the outer wall, and the strength of the hollow reinforcement tube is higher than the strength of the roller body material.

[0008] By adopting the above technical solution, the hollow reinforcing tube is used to increase the hardness of the inner walls of the roller body, the roller head and the roller neck, so that the rollers are not easily deformed.

[0009] Preferably, a plurality of reinforcing hoops are arranged on the outer wall of the roller body, and the plurality of reinforcing hoops are distributed at equal distances.

[0010] By adopting the above technical solution, the strength of the outer wall of the roller body is increased by using the reinforcing hoop.

[0011] Preferably, a plurality of reinforcement plates are symmetrically arranged inside the hollow reinforcement cylinder in the roller body and about the vertical center line of the roller body, and the size of the reinforcement plates at the two sides is smaller than that of the reinforcement plate at the middle position.

[0012] By adopting the above technical solution, multiple reinforcement plates are distributed at equal distances, which increases the support points of the roll body, roll head and roll neck to increase the strength.

[0013] Preferably, a reserved positioning hole is opened at the middle position of the reinforcement plate, and the size of the reserved positioning hole is equal to the size of the connecting pipe, and the connecting pipe passes through the reinforcement plate through the reserved positioning hole.

[0014] By adopting the above technical solution, the connecting pipe passes through the reserved positioning hole and penetrates the reinforcing plate, and the reinforcing plate has a positioning effect on the connecting pipe.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows: first, by integrating the reinforcing plate, the connecting pipe and the inlet and outlet pipe in the roller body, the two sides of the inlet and outlet pipe are located on the side away from the roller head, the cooling pipe is in the shape of a spring, and the external cold air flows along the reinforcing plate, the connecting pipe and the inlet and outlet pipe to cool the roller inside and outside at the same time. The reinforcing plate, the connecting pipe and the inlet and outlet pipe can also be used to cool the roller by flowing cold liquid along them. The roller is prevented from operating at high temperature by cold air, and the deformation problem of the roller is reduced. Second, a hollow reinforcing tube and a reinforcing plate are used to increase the strength of the roller, so that the roller is not easily deformed. By avoiding the deformation of the roller, deformation is not conducive to the subsequent continued use and leads to scrapping. BRIEF DESCRIPTION OF THE DRAWINGS

The upper and lower surfaces of the cooling pipes 6 are fitted with the hollow reinforcing cylinder 9, so that the area occupied by the cooling pipes 6 in the roller body 1, the roller head 3 and the roller neck 4 is increased, thereby increasing the heat dissipation effect of the roller body 1, the roller head 3 and the roller neck 4; connecting pipes 10 are connected and fixed between the multiple cooling pipes 6, and inlet and outlet pipes 8 are arranged on the connection pipes 10 on the left and right sides away from each other. The cooling liquid and the cooling air flow into the cooling pipe 6 through the inlet and outlet pipe 8, and then flow into the adjacent cooling pipe 6 through the connecting pipe 10. The cooling air and the cooling air flow upward in turn, and finally flow out through another inlet and outlet pipe 8, so as to realize the circulation of cooling air and the cooling liquid. In this way, the roller body 1, the roller head 3 and the roller neck 4 are cooled and cooled simultaneously inside and outside, so as to accelerate the heat dissipation speed.

[0026] A hollow reinforcement tube 9 is arranged inside the roller body 1, the roller head 3 and the roller neck 4 and at a position close to the outer wall, and the strength of the hollow reinforcement tube 9 is higher than the material strength of the roller body 1. The hollow reinforcement tube 9 increases the strength area of ​​the roller body 1, the roller head 3 and the roller neck 4, and increases the strength of the roller body 1, the roller head 3 and the roller neck 4, so that the roller body 1, the roller head 3 and the roller neck 4 are not easily deformed, thereby increasing the service life of the roller body 1, the roller head 3 and the roller neck 4.

[0027] A plurality of reinforcing hoops 2 are arranged on the outer wall of the roller body 1, and the plurality of reinforcing hoops 2 are distributed at equal distances. The reinforcing hoops 2 are used to increase the strength of the outer part of the roller body 1, and further increase the strength of the roller body 1, so that the roller body 1 is not easily deformed. A plurality of reinforcing plates 5 are symmetrically arranged inside the hollow reinforcing cylinder 9 in the roller body 1 about the vertical center line of the roller body 1, and the size of the reinforcing plates 5 located on both sides is smaller than the size of the reinforcing plates 5 located in the middle position. The outer wall of the reinforcing plate 5 and the inner wall of the hollow reinforcing cylinder 9 are tightly fitted; the reinforcing plates 5 are used to increase the support points at multiple locations of the inner wall of the hollow reinforcing cylinder 9. Since the reinforcing plates 5 are made of high-strength materials, the strength effect is increased by the reinforcing plates 5; in addition, a reserved positioning hole 11 is opened at the middle position of the reinforcing plate 5, and the size of the reserved positioning hole 11 is equal to the size of the connecting pipe 10, and the connecting pipe 10 passes through the reinforcing plate 5 through the reserved positioning hole 11.
