Description

Technical Field

[0001] The utility model belongs to the technical field of rubber roller equipment, and particularly relates to a highly wear-resistant and anti-slip rubber roller. Background Art

[0002] A rubber roller is a roller-shaped product with a metal or other material core and a rubber outer covering vulcanized thereon. Since the rubber skin of a conventional rubber roller is directly exposed, during the working process, the rubber skin will directly contact high-temperature products. Due to the direct heat absorption of the rubber skin, the rubber skin of the conventional rubber roller may be easily deformed by high-temperature heating.

[0003] In the prior art, the ends of the rubber rollers disclosed are all in a fixed welding form. When the roller ends are damaged, the rubber rollers need to be replaced, which is costly. At the same time, since the rubber rollers are severely damaged during long-term use, the rubber rollers need to be re-coated. If the above-mentioned fixed welding form is used for the roller ends, since the two ends of the rubber tube are slender end shaft structures, it is time-consuming and laborious to position the rubber tube.

[0004] In view of the above factors, a highly wear-resistant and anti-slip rubber roller is provided, which increases the friction of the roller surface of the material during use and improves the exhaust effect of forming an air vacuum between the roller and the working film during high-speed rotation. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a highly wear-resistant and anti-slip rubber roller to solve the problems raised in the above background art.

[0006] The purpose of the utility model is achieved by the following technical solutions: a highly wear-resistant and anti-slip rubber roller, comprising a rubber roller body and a first shaft head and a second shaft head detachably connected to both ends of the rubber roller body. The rubber roller body includes a roller core and a roller rubber layer coated on the outer side of the roller core;

[0007] One end of the first shaft head extends into the rubber roller body, and the other end extends out of the rubber roller body; one end of the second shaft head extends into the rubber roller body, and the other end extends out of the rubber roller body;

[0008] Both ends of the first shaft head and the second shaft head are detachably connected with shaft head closing covers.

[0009] Further, the detachable connection between both ends of the first shaft head and the second shaft head and the shaft head closing covers is a bolt connection.

[0010] Further, stepped sealing surfaces are fixedly arranged on the inner sides of both ends of the rubber roller body, and the first shaft head and the second shaft head extend into the rubber roller body and contact the stepped sealing surfaces.

[0011] Furthermore, the first shaft head and the second shaft head are provided with a stepped shaft structure, and rubber-coated bearings are detachably connected to the outer ends of the first shaft head and the second shaft head.

[0012] Furthermore, the detachable connection mode between the two ends of the rubber roller body and the first shaft head and the second shaft head is a threaded connection.

[0013] Furthermore, the roller core is made of a metal material, and the roller rubber layer coated on the outer side of the roller core includes a polytetrafluoroethylene layer and a rubber base layer arranged on the inner side of the polytetrafluoroethylene layer. A flame retardant layer is arranged between the rubber base layer and the polytetrafluoroethylene layer.

[0014] Furthermore, the roller core is made of a metal material, and the surface of the roller rubber layer coated on the outer side of the roller core is provided with channels.

[0015] Furthermore, the channels include spiral grooves, diamond grooves or herringbone grooves.

[0016] Furthermore, the channels extend inward from the outer surface of the roller rubber layer to a depth of 3-5 mm, and the channels do not penetrate the rubber base layer.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] In order to facilitate detachable replacement in the use state, the detachable connection mode between the two ends of the rubber roller body and the first shaft head and the second shaft head is a bolt connection. With the above-mentioned detachable structure, not only can it be detachably replaced, but also when re-coating the roller rubber layer, disassembling the first shaft head and the second shaft head is convenient for positioning the rubber roller body.

[0019] In order to increase the friction of the material roller surface in the use state and improve the exhaust effect of forming an air vacuum between the roller and the working film under the high-speed rotation state, the roller core is made of a metal material, and the surface of the roller rubber layer coated on the outer side of the roller core is provided with channels. The channels include spiral grooves, diamond grooves or herringbone grooves. The channels extend inward from the outer surface of the roller rubber layer to a depth of 3-5 mm, and the channels do not penetrate the rubber base layer.

[0020] When the rubber roller of the present utility model is severely damaged during long-term use and needs to be re-coated, in the use state, directly disassemble the first shaft head and the second shaft head at both ends, and use an external auxiliary installation positioning fixture to cooperate with the threaded connection of the rubber roller body for positioning.
