Technical Field

[0001] This utility model relates to the field of rubber roller technology, specifically to a tear-resistant and wear-resistant rubber roller. Background Technology

[0002] A rubber roller is a roller-shaped product made of metal or other materials as the core and covered with rubber through vulcanization. It is widely used in many industries such as papermaking, dyeing and printing, textiles, printing, grain processing, metallurgy, plastics processing, and packaging machinery.

[0003] Chinese patent CN213360841U discloses a tear-resistant and wear-resistant rubber roller, which includes a rubber roller body and rotating shafts fixedly installed on both the left and right sides of the rubber roller body.

[0004] Although the aforementioned patent effectively transfers heat to the heat dissipation strips through the installation of heat-conducting sheets during use, thereby reducing the temperature of the rubber roller and further preventing the rubber roller sleeve from aging and deforming faster due to heat, the rubber roller body is sealed at both ends by bolts to the fixing caps and fixing posts, and the shaft is then bolted to the fixing caps to connect with the rubber roller body. This makes it impossible to fix the shaft and fixing caps together to the rubber roller body, which in turn makes the installation and disassembly of the rubber roller body and the shaft inconvenient. Therefore, there is an urgent need for a new type of tear-resistant and wear-resistant rubber roller to solve these problems. Utility Model Content

[0005] (a) Technical problems to be solved The technical problem to be solved by this utility model is to provide a tear-resistant and wear-resistant rubber roller that improves the ease of disassembly and assembly, in light of the current state of the technology.

[0006] (II) Technical Solution This utility model is achieved through the following technical solution: This utility model proposes a tear-resistant and wear-resistant rubber roller, including a rubber roller body. An installation rod is centrally located inside the rubber roller body. Support plates are symmetrically fixed to the inner wall of the rubber roller body. A spring telescopic rod is installed between the installation rod and the support plates. Installation grooves are formed on the upper and lower side walls of the rubber roller body and on the side walls of the two support plates. A heat-conducting plate is installed in each installation groove. Heat dissipation fins are installed on the side wall of the heat-conducting plate facing the inner cavity of the rubber roller body. Fixed caps are fixed at both ends of the rubber roller body. A rotating shaft is connected to one side wall of each fixed cap. A fixing ring is fixed to one end of the rotating shaft adjacent to the fixed cap. An installation bolt is connected to the fixing ring through the support plate. A connecting groove is formed on the side walls of the rubber roller body between the installation grooves.

[0007] Furthermore, a roller sleeve is provided outside the rubber roller body, an adhesive layer is coated inside the connecting groove to facilitate the connection between the bearing plate and the roller sleeve, and a protective sleeve is installed outside the roller sleeve.

[0008] Furthermore, the rubber roller body is bolted to the mounting rod, the rubber roller body is bonded to the bearing plate, and both the bearing plate and the mounting rod are bolted to the spring telescopic rod.

[0009] Furthermore, both the roller sleeve and the bearing plate are bonded to the adhesive layer, and a pull wire is provided on the outside of the roller sleeve.

[0010] Furthermore, the mounting groove is formed on the rubber roller body and the bearing plate, and the mounting groove is bolted to the heat-conducting plate.

[0011] Furthermore, the heat-conducting plate is bolted to the heat sink, the rubber roller body overlaps with the fixing cover, and the fixing ring is welded to the rotating shaft.

[0012] Furthermore, the mounting bolt passes through the fixing cover and is threadedly connected to the bearing plate, and the connecting groove is formed on both sides of the rubber roller body.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model has the following advantages: This utility model sets a fixing ring at one end of the rotating shaft.

An mounting rod 2 is centrally located inside the rubber roller body 1. Bearing plates 3 are symmetrically fixed to the inner wall of the rubber roller body 1. A spring telescopic rod 4 is installed between the mounting rod 2 and the bearing plates 3. The rubber roller body 1 can more firmly fix the mounting rod 2, and the spring telescopic rod 4 can buffer the pressure borne by the bearing plates 3, thereby reducing the pressure borne by the roller sleeve 13. Mounting grooves 5 are provided on the upper and lower side walls of the rubber roller body 1 and the side walls of the two bearing plates 3. A heat-conducting plate 6 is installed in each mounting groove 5. The mounting grooves 5 can firmly fix the heat-conducting plate 6 to the rubber roller body 1, and the heat-conducting plate 6 can buffer the pressure borne by the roller sleeve 13. The heat is conducted away, thereby achieving heat dissipation of the roller sleeve 13. Heat dissipation fins 7 are installed on the side wall of the heat conduction plate 6 facing the inner cavity of the rubber roller body 1. Fixed covers 8 are fixed at both ends of the rubber roller body 1. A rotating shaft 9 is connected to one side wall of the fixed cover 8. A fixed ring 10 is fixed to one end of the rotating shaft 9 adjacent to the fixed cover 8. A mounting bolt 11 is connected to the fixed ring 10 through the bearing plate 3. The fixed ring 10 and the mounting bolt 11 cooperate to fix the fixed cover 8 together with the rotating shaft 9 to the rubber roller body 1, improving the ease of installation between the rubber roller body 1, the fixed cover 8 and the rotating shaft 9, and also facilitating the easy disassembly of each part. A connecting groove 12 is opened between the two side walls of the rubber roller body 1 located between the mounting grooves 5.
