Description

Technical Field

[0001] The utility model relates to the technical field of rubber rollers, in particular to a high-temperature resistant composite rubber roller. Background Art

[0002] Rubber rollers are widely used in conveying equipment in fields such as printing and dyeing, textile, papermaking, and metallurgy. In the metallurgy field, the surface temperature of steel is usually above 200 °C, and the rubber roller will be continuously exposed to high temperatures. However, the existing rubber rollers do not have a good heat dissipation structure. When the rubber roller is in a high-temperature state for a long time, it is easy to age rapidly and needs improvement. Content of the Utility Model

[0003] To solve the problems mentioned in the background art, the purpose of the utility model is to provide a high-temperature resistant composite rubber roller.

[0004] To achieve the above goal, the technical solution of the utility model is as follows:

[0005] The high-temperature resistant composite rubber roller includes a cylinder body, two shaft heads, a screw shaft, and a contact cylinder. A rubber coating layer is provided on the outer part of the cylinder body. The two shaft heads are respectively welded inside the two end ports of the cylinder body. The screw shaft is coaxially arranged inside the cylinder body. The blades of the screw shaft are in contact with the inner wall of the cylinder body. The blades at both axial ends of the screw shaft are welded to the cylinder body. At both axial ends of the screw shaft, contact cylinders are coaxially welded respectively. The two contact cylinders are respectively in contact with the flange plates of the two shaft heads. A number of water permeable holes are evenly distributed on the circumferential surface of the contact cylinder. A coolant flow channel communicating with the contact cylinder is provided inside the shaft head.

[0006] Furthermore, the shaft part of the screw shaft is hollow.

[0007] The beneficial effect of the utility model is that coolant can be injected into the cylinder body through the coolant flow channel of one shaft head. After being guided by the blades of the screw shaft, the coolant is discharged through the coolant flow channel of the other shaft head. The coolant can evenly cool the surface of the cylinder body, thereby cooling the rubber coating layer on the surface of the cylinder body and improving the heat resistance of the rubber coating layer.

[0011] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art shall fall within the protection scope of the present utility model.

[0012] As Figure 1 - Figure 2 shown, the high-temperature resistant composite rubber roll includes a cylinder body 1, two shaft heads 2, a dragon shaft 3 and a contact cylinder 4. A rubber coating layer 5 is provided on the outer part of the cylinder body 1, and the rubber coating layer 5 is made of rubber. The two shaft heads 2 are respectively welded inside the two end ports of the cylinder body 1. The dragon shaft 3 is coaxially arranged inside the cylinder body 1. The blades of the dragon shaft 3 are in contact with the inner wall of the cylinder body 1. The blades at both axial ends of the dragon shaft 3 are welded to the cylinder body 1. The shaft part of the dragon shaft 3 is hollow. Specifically, the shaft part of the dragon shaft 3 is in the shape of a cylinder with both ends closed. At both axial ends of the dragon shaft 3, contact cylinders 4 are coaxially welded respectively. The two contact cylinders 4 are respectively in contact with the flange plates of the two shaft heads 2. A plurality of water permeable holes 41 are evenly distributed on the circumferential surface of the contact cylinder 4. A coolant flow channel 21 communicating with the contact cylinder 4 is provided inside the shaft part of the shaft head 2.

[0013] When the rubber roll rotates, one shaft head 2 can be connected to the coolant conduit through a rotary joint, and coolant is injected into the cylinder body 1 through the coolant flow channel 21 of one shaft head 2. After the coolant is guided by the blades of the dragon shaft 3, it is discharged through the coolant flow channel 21 of the other shaft head 2. Due to the arrangement of the dragon shaft 3, the space for the coolant to flow inside the cylinder body 1 is reduced, and the blades of the dragon shaft 3 can guide the coolant, so that the coolant can quickly and evenly cool the surface of the cylinder body 1, thereby cooling the rubber coating layer on the surface of the cylinder body 1 and improving the heat resistance of the rubber coating layer.

[0014] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. All any modifications, equivalent replacements, improvements, etc. within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
