Description

Technical Field

[0001] The utility model relates to the technical field of tension rollers, in particular to a wear-resistant and anti-skid tension roller. Background Art

[0002] In the process of wet descaling, the strip needs to pass through the tension roller at the inlet and the tension roller at the outlet to adjust the tension. Before and after descaling, the surface of the strip treated by the traditional wet descaling machine often contains water and scale slag. When the descaling unit is running, the tension roller runs vigorously and at high speed. The moisture and scale slag on the surface of the strip can easily cause the strip to slip, thereby affecting the tension and speed control of the strip. In order to solve the above problems, a patent document with the authorization announcement number CN108906896B discloses an anti-skid tension roller, which is provided with a grid-shaped water collection trough on the surface of the cylindrical roller body, and uses the grid-shaped water collection trough to receive the water and slag falling on the surface of the cylindrical roller body. The water and slag are then discharged from the two ends of the axial direction of the cylindrical roller body, changing the problem that the traditional tension roller cannot drain water and the tension roller lining wears quickly, thereby improving the wear resistance and anti-skid performance of the tension roller. It has certain water drainage and slag removal performance, but has defects, because the water entering the cylindrical roller body is not necessarily discharged from the two ends of the axial direction of the cylindrical roller body, but may be discharged in the opposite direction through the drainage screws to the surface of the cylindrical roller body. Therefore, the inner diameter of the drainage screw cannot be too large, or the drainage screw can be made longer. Regardless of reducing the inner diameter of the drainage screw or increasing the length of the drainage screw, it will have a negative impact on the water drainage and slag removal capabilities of the cylindrical roller body. Utility Model Content

[0003] In order to solve the problems mentioned in the background technology, the purpose of the utility model is to provide a wear-resistant and anti-skid tension roller.

[0004] In order to achieve the above objectives, the technical solution of the utility model is:

[0005] A wear-resistant and non-slip tension roller comprises a cylindrical roller body and an axle head assembly, both ends of the cylindrical roller body are provided with axle head assemblies in the axial direction, a plurality of drainage holes are transparently arranged on the circumferential surface of the cylindrical roller body, a center cylinder is coaxially arranged inside the cylindrical roller body, a plurality of partitions are evenly arranged on the outer circumferential surface of the center cylinder, the outer edges of the partitions are welded to the inner wall of the cylindrical roller body, and an independent drainage area is formed between two adjacent partitions, the axle head assembly comprises a step shaft, an outer flange and an inner flange, the inner flange is fixedly connected to the end of the large diameter section of the step shaft, the outer flange is fixedly connected to the middle of the large diameter section of the step shaft, the inner flange abuts against the end of the center cylinder, the outer flange is welded to the inner wall of the cylindrical roller body, the inner flange is provided with a first drainage port corresponding to each drainage area, and a plurality of second drainage ports are provided on the edge of the outer flange.

[0006] Furthermore, the radius of the central tube gradually increases from both ends of its own axial direction to the center.

[0007] Furthermore, the first drain port is in a fan-shaped shape, and the inner side of the first drain port is connected to the edge of the end of the central tube.

[0008] Furthermore, the second drain port is semicircular.

[0009] The beneficial effects of the utility model are as follows: by arranging drainage holes on the surface of the cylindrical roller body, water and slag attached to the surface of the strip can be discharged into the interior of the cylindrical roller body; under the action of the central tube and the partition, the water entering the interior of the cylindrical roller body can only be discharged from the two ends of the axial direction of the cylindrical roller body, and will no longer be discharged in the reverse direction through the drainage holes onto the surface of the cylindrical roller body; in this way, the drainage holes can be made larger, which not only increases the absorption capacity of the drainage holes for slag and water, but also ensures the discharge speed of slag and water, thereby improving the slag discharge and water discharge capacity of the cylindrical roller body, thereby increasing the wear resistance and anti-skid performance of the cylindrical roller body in disguised form.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.

[0016] like Figure 1-Figure 4As shown, a wear-resistant and non-slip tension roller comprises a cylindrical roller body 1 and a shaft head assembly. Both ends of the cylindrical roller body 1 are provided with shaft head assemblies in the axial direction. Twelve strip-shaped drainage holes 11 are transparently arranged on the circumferential surface of the cylindrical roller body 1. The twelve drainage holes 11 are evenly arranged along the circumference of the cylindrical roller body 1. A central cylinder 2 is coaxially arranged inside the cylindrical roller body 1. Four partitions 21 are evenly arranged on the outer circumferential surface of the central cylinder 2. The outer sides of the partitions 21 are welded to the inner wall of the cylindrical roller body 1. An independent drainage area is formed between two adjacent partitions 21. The shaft head assembly It includes a stepped shaft 3, an outer flange 31 and an inner flange 32. The inner flange 32 is welded to the end of the large diameter section of the stepped shaft 3, the outer flange 31 is welded to the middle of the large diameter section of the stepped shaft 3, the inner flange 32 and the outer flange 31 are arranged at intervals, the inner flange 32 abuts against the end of the center tube 2, the outer flange 31 is welded to the inner wall of the cylindrical roller body 1, the inner flange 32 is provided with first drain ports 321 corresponding to four drain areas, the edge of the outer flange 31 is provided with four second drain ports 311, and the four second drain ports 311 are evenly arranged along the circumference of the outer flange 31.

[0017] In practical applications, water and debris attached to the surface of the strip can be discharged into the interior of the cylindrical roller body 1. Under the action of the center tube 2 and the partition 21, the water entering the cylindrical roller body 1 can only be discharged into the space between the inner flange 32 and the outer flange 31 through the first drainage port 321, and then discharged through the second drainage port 311. Generally speaking, the water and debris entering the cylindrical roller body 1 can only be discharged from the two axial ends of the cylindrical roller body 1, and will no longer be discharged on the surface of the cylindrical roller body 1 through the drainage hole 11 in the reverse direction.

[0018] In this embodiment, the radius of the central tube 2 gradually increases from the two axial ends to the center, and the design is reasonable, which can guide the slag and water to move to the two axial ends of the cylindrical roller body 1.

[0019] In this embodiment, the first drain port 321 is fan-shaped, and the inner side of the first drain port 321 is connected to the edge of the end of the central tube 2. The design is reasonable to avoid the inner flange 32 from interfering with the discharge of debris and water.

[0020] In this embodiment, the second drain port 311 is semicircular, which can ensure the strength of the outer flange 31 and thus ensure the stability of the connection between the outer flange 31 and the cylindrical roller body 1 .

[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. All modifications, equivalent substitutions, improvements, etc. within the spirit and principles of the present invention should be included in the protection scope of the present invention.
