Description

Technical Field

[0001] The utility model relates to the technical field of rubber rollers, in particular to a rubber roller with high elasticity and easy peeling. Background Art

[0002] Rubber rollers are usually used in various mechanical equipment, such as belt conveyors, rubber kneaders, rubber pulverizers, etc. In these devices, the rubber roller processes rubber or other materials through actions such as rotation and extrusion. During this process, due to friction and mechanical energy conversion, a large amount of heat is generated on the roller, and the high temperature will soften the surface of the rubber roller, thereby increasing the adhesion force of the outer circular surface of the rubber roller, making it difficult to peel the contact material adhered to the rubber roller, and affecting the use effect of the rubber roller.

[0003] In view of the above related technologies, the inventor found that the heat dissipation of the existing rubber roller usually achieves the purpose of cooling by increasing the surface area of the roller and reducing the ambient temperature, etc. However, the heat inside the rubber roller cannot be discharged in time, and the heat inside the rubber roller is transferred to its outer circular surface, thereby increasing the adhesion force of the outer surface of the rubber roller and reducing the use effect. Summary of the Utility Model

[0004] The main technical problem to be solved by the utility model is to provide a rubber roller with high elasticity and easy peeling. The spiral blade drives the cold gas to contact the inner surface of the highly elastic rubber cylinder, reducing the temperature of the highly elastic rubber cylinder and improving the peeling effect of the rubber roller, that is, enhancing the use effect.

[0005] To solve the above technical problem, a technical solution adopted by the utility model is: to provide a rubber roller with high elasticity and easy peeling, including: a roller body and hollow shafts connected to both ends thereof. A highly elastic rubber cylinder is sleeved and connected to the outer circle of the roller body. A rotating shaft is arranged in the inner cavity of the roller body. A spiral blade is sleeved and connected to the outer circle of the rotating shaft. One end of the rotating shaft passes through the hollow shaft at the left end and is rotationally connected through a bearing. The other end of the rotating shaft is rotationally connected to a hollow-shaped support seat assembly. The hollow-shaped support seat assembly is connected to the inner wall at the right end of the roller body. The hollow shaft at the right end is connected to a rotary joint. The rotary joint is connected to an external cold gas source through a pipeline;

[0006] It also includes a gas flow channel and a transmission mechanism. The hollow shaft at the left end drives the rotating shaft to rotate through the transmission mechanism. The gas flow channel is used to guide the gas in the roller body to flow to the external environment after contacting the highly elastic rubber cylinder.

[0007] By adopting the above technical solution, during the use of the rubber roller, due to friction and mechanical energy conversion, a large amount of heat will also be generated inside the rubber roller. At this time, the gas from the external cold gas source enters the inner cavity of the roller body through the rotating joint and the hollow shaft. The rotating roller body drives the hollow shaft to rotate. The hollow shaft drives the rotating shaft to rotate through the transmission mechanism. The rotating shaft drives the spiral blade to rotate. The spiral blade rotates and squeezes the cold gas, facilitating the uniform contact of the cold gas with the inner surface of the high-elastic rubber cylinder through the gas flow channel and then flowing into the external environment, quickly taking away the heat contained in the high-elastic rubber cylinder, achieving the purpose of rapid cooling, improving the peeling effect of the rubber roller, that is, enhancing the use effect of the rubber roller. Since the spiral blade has a squeezing effect on the cold gas, the cold gas source does not need to release cold gas at a large pressure, reducing the flow rate of the cold gas, facilitating the full use of the cold gas to cool the high-elastic rubber cylinder, and reducing the use cost.

[0008] In a preferred embodiment of the present utility model, it can be further configured that: the gas flow channel includes a plurality of ventilation holes spaced on the roller body and a plurality of annular grooves spaced on the inner surface of the high-elastic rubber cylinder. The ventilation holes correspond to and communicate with the annular grooves. The inner surface of the high-elastic rubber cylinder is annularly and arrayedly penetrated with a plurality of rectangular grooves.

[0009] By adopting the above technical solution, the cold gas enters the roller body, the spiral blade squeezes the cold gas, the cold gas flows into the annular groove after passing through the ventilation hole, and the cold gas in the annular groove then flows into the rectangular groove, so that the cold gas fully contacts the high-elastic rubber cylinder, and the gas that absorbs more heat is discharged to the external environment through the rectangular groove to achieve the purpose of cooling.

[0010] In a preferred embodiment of the present utility model, it can be further configured that: the hollow-shaped support seat assembly includes a circular support seat body and a plurality of fixing rods. The fixing rods are annularly arrayed and one end is connected to the circular support seat body, and the other end is connected to the inner wall of the end of the roller body. The circular support seat body is rotatably connected to the rotating shaft.

[0011] By adopting the above technical solution, the circular support seat body rotatably supports the rotating shaft, and the gap between adjacent fixing rods facilitates the flow of cold gas.

[0012] In a preferred embodiment of the present utility model, it can be further configured that: the transmission mechanism includes a driving gear, a driven gear and an intermediate gear. The driving gear is sleeved and connected to the hollow shaft at the left end. The driven gear is sleeved and connected to the outer circle of the end of the rotating shaft. The driving gear is meshed and connected to the driven gear through the intermediate gear. It further includes a U-shaped seat and a support shaft passing through the U-shaped seat. The support shaft is rotatably connected to the U-shaped seat. The intermediate gear is sleeved and connected to the support shaft. The lower plane of the U-shaped seat is connected with a horizontal plate.

[0013] By adopting the above technical solution, the rotation of the roller body drives the hollow shaft to rotate, the hollow shaft drives the driving gear to rotate, the driving gear drives the driven gear to rotate through the intermediate gear, the driven gear drives the rotating shaft to rotate, and the rotating shaft drives the spiral blade to perform spiral transmission and extrusion on the cold gas.

[0014] In a preferred example, the present utility model can be further configured as: mounting seats are respectively sleeved on the hollow shaft, and the mounting seat at the left end is connected to the horizontal plate.

[0015] By adopting the above technical solution, the lower end of the mounting seat is connected to the equipment using the rubber roller, the mounting seat supports and rotatably connects the roller body, and the mounting seat indirectly fixes the U-shaped seat through the horizontal plate.

[0016] In a preferred example, the present utility model can be further configured as: an annular baffle is connected inside the hollow shaft at the left end, the annular baffle is sleeved on the rotating shaft, and is adapted to prevent the gas from flowing out through the inner hole of the hollow shaft.

[0017] By adopting the above technical solution, through the use of the annular baffle, the gas is prevented from flowing out through the inner hole of the hollow shaft, facilitating the gas flowing into the roller body to fully contact the inner surface of the high-elastic rubber cylinder.

[0018] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0019] The rotating spiral blade performs rotating transmission and extrusion on the cold gas, facilitating the cold gas to uniformly flow through the gas flow channel, contact the inner surface of the high-elastic rubber cylinder, and then flow into the external environment, quickly taking away the heat contained in the high-elastic rubber cylinder, achieving the purpose of rapid cooling, improving the peeling effect of the rubber roller, that is, enhancing the use effect of the rubber roller.

A high-elastic rubber cylinder 3 is sleeved and connected to the outer circle of the roller body 1. A rotating shaft 4 is provided in the inner cavity of the roller body 1.

One end of the rotating shaft 4 passes through the hollow shaft 2 at the left end and is rotationally connected through a bearing. The other end of the rotating shaft 4 is rotationally connected to a hollow support base assembly 60. The hollow support base assembly 60 is connected to the inner wall at the right end of the roller body 1. The hollow shaft 2 at the right end is connected to a rotating joint 9. The rotating joint 9 is connected to an external cold gas source through a pipeline; the gas from the cold gas source enters the inside of the roller body 1 through the pipeline, the rotating joint 9 and the hollow shaft 2. The rubber roller of the present application is used as a driven roller, and an external power source can be connected by a belt or in rolling contact therewith to drive the rubber roller of the present application to rotate.

[0032] It also includes a gas flow channel 70 and a transmission mechanism 80. The hollow shaft 2 at the left end drives the rotating shaft 4 to rotate through the transmission mechanism 80. The transmission mechanism 80 includes a driving gear 81, a driven gear 82, and an intermediate gear 83. The driving gear 81 is sleeved and connected to the hollow shaft 2 at the left end. The driven gear 82 is sleeved and connected to the outer circumference of the end of the rotating shaft 4. The driving gear 81 is meshed and connected to the driven gear 82 through the intermediate gear 83. It also includes a U-shaped seat 84 and a support shaft 85 passing through the U-shaped seat 84. The support shaft 85 is rotatably connected to the U-shaped seat 84. The intermediate gear 83 is sleeved and connected to the support shaft 85. The lower plane of the U-shaped seat 84 is connected with a horizontal plate 86. The rotation of the roller body 1 drives the hollow shaft 2 to rotate. The hollow shaft 2 drives the driving gear 81 to rotate. The driving gear 81 drives the driven gear 82 to rotate through the intermediate gear 83. The driven gear 82 drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the spiral blade 5 to conduct spiral transmission and extrusion of the cold gas.

[0033] Mounting seats 11 are respectively sleeved on the hollow shaft 2. The mounting seat 11 at the left end is connected with the horizontal plate 86. The lower end of the mounting seat 11 is connected to the equipment using the rubber roller. The mounting seat 11 supports and rotatably connects the roller body 1. The mounting seat 11 indirectly fixes the U-shaped seat 84 through the horizontal plate 86.

[0034] The gas flow channel 70 is used to guide the gas in the roller body 1 to flow to the external environment after contacting the highly elastic rubber cylinder 3. The gas flow channel 70 includes a number of ventilation holes 71 spaced apart on the roller body 1 and a number of annular grooves 72 spaced apart on the inner surface of the highly elastic rubber cylinder 3. The ventilation holes 71 correspond to and communicate with the annular grooves 72. A number of rectangular grooves 73 are provided in an annular array through the inner surface of the highly elastic rubber cylinder 3. The cold gas enters the roller body 1. The spiral blade 5 extrudes the cold gas. The cold gas flows into the annular groove 72 after passing through the ventilation holes 71. The cold gas in the annular groove 72 then flows into the rectangular grooves 73, enabling the cold gas to fully contact the highly elastic rubber cylinder 3. The gas that absorbs more heat is discharged to the external environment through the rectangular grooves 73 to achieve the purpose of cooling.

[0035] The hollow-shaped support seat assembly 60 includes a circular support seat body 61 and a number of fixing rods 62. The fixing rods 62 are arranged in an annular array and one end is connected to the circular support seat body 61, and the other end is connected to the inner wall of the end of the roller body 1. The circular support seat body 61 is rotatably connected to the rotating shaft 4. The circular support seat body 61 rotatably supports the rotating shaft 4.

[0036] An annular baffle 12 is connected inside the hollow shaft 2 at the left end. The annular baffle 12 is sleeved on the rotating shaft 4 and is adapted to prevent gas from flowing out through the inner hole of the hollow shaft 2. By using the annular baffle 12, the gas is prevented from flowing out through the inner hole of the hollow shaft 2, facilitating the gas flowing into the roller body 1 to fully contact the inner surface of the highly elastic rubber cylinder 3.

[0037] The implementation principle of this embodiment is as follows: During the use of the rubber roller, due to friction and mechanical energy conversion, a large amount of heat is also generated inside the rubber roller. At this time, the gas from the external cold gas source enters the inner cavity of the roller body 1 through the rotating joint 9 and the hollow shaft 2. The rotating roller body 1 drives the hollow shaft 2 to rotate. The hollow shaft 2 drives the rotating shaft 4 to rotate through the transmission mechanism 80. The rotating shaft 4 drives the spiral blade 5 to rotate. The spiral blade 5 rotates and squeezes the cold gas, facilitating the cold gas to uniformly pass through the gas flow channel 70, contact the inner surface of the highly elastic rubber cylinder 3, and then flow into the external environment, quickly taking away the heat contained in the highly elastic rubber cylinder 3, achieving the purpose of rapid cooling, improving the peeling effect of the rubber roller, that is, enhancing the use effect of the rubber roller. Since the spiral blade 5 has an extrusion effect on the cold gas, the cold gas does not need to be released under a large pressure, reducing the flow rate of the cold gas, facilitating the full use of the cold gas to cool the highly elastic rubber cylinder 3. Since the cold gas is made by a refrigeration device, the purpose of reducing the use cost is achieved.
