Description

Technical Field

[0001] The utility model relates to the technical field of turning rollers, in particular to a steel double-chain conical turning roller. Background Art

[0002] Tapered rollers are an important component of roller conveyors for turning. The diameter of tapered rollers gradually changes along the axial direction. As cargo moves along these rollers, they are affected by a force that gradually changes direction due to the changing roller diameter, thereby achieving a smooth 90-degree turn. By arranging multiple rollers at different angles, cargo is guided to gradually change direction during transportation, ultimately achieving turns on complex paths.

[0003] Patent application number CN202323110219.0 discloses a special-shaped roller used at the turning point of a belt conveyor, including a bearing bracket, a filling bracket inserted and installed on the inner wall of the intermediate roller body, and fixed thread grooves are opened on the edges of both ends of the intermediate roller body, and a fixed thread block is spirally installed on the inner wall of the fixed thread groove, and one end of the fixed thread block is fixedly connected to the edge of the connecting end cover, and a splicing slide bead is inlaid and installed on the edge of one end of the connecting end cover, and the other side of the splicing slide bead is inserted and installed on the edge of one end of the roller body at both ends. The special-shaped roller used at the turning point of the belt conveyor can make the contact area of ​​the belt larger during operation through the tapered structure of the roller bodies at both ends, which can reduce the belt indentation resistance, thereby improving the performance of the special-shaped roller, and the anti-corrosion rubber material of the outer pad increases the friction force, and the movement is stable. The independent rolling structure of the roller bodies at both ends can roll smoothly, and the roller bodies at both ends are easy to disassemble and replace independently, which is more convenient to use. However, the roller has the following problems: First, the roller cannot remove the static electricity generated by friction with the material when transporting the material, and secondly, the roller cannot cool the internal motor temperature. Utility Model Content

[0004] The purpose of the utility model is to address the shortcomings of the existing technology. By setting up a static dissipation rubber, the technical problem that the roller cannot remove the static electricity generated by the friction with the material when transporting the material is solved. By using a heat dissipation ring, the technical problem that the roller cannot cool the internal motor temperature is solved.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A steel double-chain conical turning roller comprises a conical roller shell, a double sprocket is provided at the front end of the conical roller shell, a power unit is provided at the rear end of the conical roller shell, a roller front cover is provided at the front end of the conical roller shell, a roller rear cover is provided at the rear end of the conical roller shell, an anti-static rubber is provided on the outside of the conical roller shell, a pressure-resistant layer is provided on the inside of the conical roller shell, and a heat dissipation ring is provided on the inside of the pressure-resistant layer.

[0007] As a preferred embodiment, a power casing is provided on the outside of the power unit, a motor is provided at the front end of the inside of the power unit, a reduction gear is provided at the rear end of the motor, an output shaft is provided at the rear end center of the reduction gear, the output shaft protrudes from the rear cover of the roller, a roller shaft is provided at the front end center of the motor, the roller shaft protrudes from the front cover of the roller, a power cord is provided inside the roller shaft, and the power cord is electrically connected to the motor.

[0008] As a preferred embodiment, heat pipes are evenly arranged inside the heat dissipation ring, a seamless copper shell is provided on the outside of the heat pipe, a liquid absorption core layer is provided on the inside of the seamless copper shell, a vacuum channel is provided inside the heat pipe, and a refrigerant is provided inside the vacuum channel.

[0009] As a preferred embodiment, the double sprocket is welded to the outer side of the front end of the tapered roller shell into one body.

[0010] As a preferred embodiment, the outer surface of the anti-static rubber is evenly provided with patterned protrusions.

[0011] As another preferred embodiment, the compression-resistant layer is entirely made of a carbon fiber layer.

[0012] Beneficial effects of the utility model:

[0013] (1) In the present invention, heat is dissipated from the inside of the roller by setting a heat dissipation ring. When the roller runs at no-load for a long time, the heat accumulated inside the roller will cause the temperature to rise sharply, causing the motor to burn out. The heat pipe inside the heat dissipation ring can dissipate the heat from the inside of the roller. When the heat at the motor position begins to rise, the seamless copper shell of the heat pipe at the motor position will be in contact with the heat, and the refrigerant in the internal vacuum channel will vaporize. At this time, the front end of the conical roller shell is located at the temperature cold end. The vaporized refrigerant reaches the temperature cold end, turns back into liquid, releases a large amount of heat, and then flows back to the temperature hot end, repeating in sequence, thereby achieving the purpose of heat dissipation at the motor and ensuring the safety of the motor inside the roller when it is at no-load for a long time.

[0014] (2) In the present invention, an anti-static rubber is provided to prevent static electricity generated by the friction between the material and the conical roller shell. The roller is prone to generate static electricity during use, causing the charged material to be adsorbed on the conveyor belt during transportation, increasing the difficulty of transportation. When static charge accumulates on the outer surface of the conical roller shell, the conductive particles in the anti-static rubber will interact with the charge, causing the charge to be neutralized, thereby preventing the generation and accumulation of static electricity, making transportation smoother and not affected by static electricity accumulation. At the same time, the outer side of the anti-static rubber is evenly provided with patterned protrusions to prevent the material from slipping, making transportation more stable and non-slip.

[0015] (3) In the present invention, the compression-resistant layer is set as a carbon fiber layer to avoid the aggravated wear of the conical roller shell due to uneven force. The carbon fiber layer has extremely high specific strength and specific modulus. When bearing the same weight, the carbon fiber layer can provide better structural support and is not easy to deform, thereby maintaining the stability of the conical roller shell when transporting items.

[0016] In summary, the roller has the advantages of ensuring the safety of the internal motor when the roller is unloaded for a long time, making it more stable during transportation, and preventing the generation and accumulation of static electricity. It is particularly suitable for the field of turning roller technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present utility model are clearly and completely described below with reference to the accompanying drawings.

[0024] Example 1

[0025] like Figures 1 to 4 As shown, the utility model is a steel double-chain conical turning roller, comprising a conical roller shell 1, a double sprocket 11 is provided at the front end of the conical roller shell 1, a power unit 2 is provided at the rear end of the conical roller shell 1, a roller front cover 12 is provided at the front end of the conical roller shell 1, a roller rear cover 13 is provided at the rear end of the conical roller shell 1, an anti-static rubber 16 is provided on the outside of the conical roller shell 1, a pressure-resistant layer 17 is provided on the inside of the conical roller shell 1, and a heat dissipation ring 15 is provided on the inside of the pressure-resistant layer 17.

[0026] Furthermore, a power casing 21 is provided on the outside of the power unit 2, and a motor 22 is provided at the front end inside the power unit 2 to provide driving force for the roller. A reduction gear 23 is provided at the rear end of the motor 22, and a rotating shaft is provided at the center of the motor 22. The rotating shaft is connected to the reduction gear 23, and an output shaft 24 is provided at the rear end center of the reduction gear 23. The output shaft 24 protrudes from the roller rear cover 13, and a roller shaft 221 is provided at the front end center of the motor 22. The roller shaft 221 protrudes from the roller front cover 12, and a power cord is provided inside the roller shaft 221. The power cord extends to the outside to connect to an external power supply, and the power cord is electrically connected to the motor 22.

[0027] Furthermore, heat pipes 151 are evenly arranged inside the heat dissipation ring 15, and a seamless copper shell 152 is provided on the outside of the heat pipe 151, and a liquid-absorbing core layer 153 is provided on the inside of the seamless copper shell 152. A vacuum channel 154 is provided inside the heat pipe 151, and a refrigerant is provided inside the vacuum channel 154. When the heat at the position of the motor 22 begins to rise, the seamless copper shell 152 of the heat pipe 151 at the position of the motor 22 is in contact with the heat, and the refrigerant in the internal vacuum channel 154 will vaporize. At this time, the front end of the tapered roller shell 1 is located at the temperature cold end. The vaporized refrigerant comes to the temperature cold end, turns back into liquid, releases a large amount of heat, and then flows back to the temperature hot end, and repeats in sequence, so as to achieve the purpose of heat dissipation at the motor 22 and ensure the safety of the motor inside the roller when it is no-loaded for a long time.

[0028] Furthermore, the double sprocket 11 is welded to the outer front end of the tapered roller shell 1 to form a whole, so that it can better transmit higher torque and better meet the needs of heavy-duty transportation.

[0029] Furthermore, the outer surface of the anti-static rubber 16 is evenly provided with patterned protrusions to prevent slipping when transporting objects.

[0030] Furthermore, the anti-compression layer 17 is entirely made of a carbon fiber layer, which can provide better structural support and is not easily deformed, thereby maintaining the stability of the tapered roller shell 1 when transporting items.

[0031] Working process: First, after connecting the power cord to the external power supply, the voltage is applied to the motor 22, and the motor 22 generates rotational power. The reduction gear 23 receives the rotational power of the motor 22, and amplifies the torque while reducing the speed. The force is transmitted to the conical roller shell 1 through the output shaft 24, forming a circular motion to transport objects. When the conical roller shell 1 runs at no load for a long time, the heat accumulation inside the conical roller shell 1 will increase sharply, causing the motor 22 to burn. The heat pipe 151 inside the heat dissipation ring 15 can dissipate the heat inside the conical roller shell 1. When the heat at the position of the motor 22 begins to rise, the seamless copper shell of the heat pipe 151 at the position of the motor 22 is exposed to heat at 152, and the refrigerant in the internal vacuum channel 154 will vaporize. At this time, the front end of the conical roller shell 1 is at a temperature At the cold end, the vaporized refrigerant reaches the cold end and turns back into liquid, releasing a large amount of heat, and then flows back to the hot end, repeating this process, so as to achieve the purpose of heat dissipation at the motor 22, ensuring the safety of the motor 22 inside the conical roller shell 1 when it is unloaded for a long time. At the same time, when the conical roller shell 1 transports items, the friction between the material and the conical roller shell 1 will generate static electricity, which will cause the charged materials to be adsorbed on the conveyor belt during transportation, increasing the difficulty of transportation. When static charge accumulates on the outer surface of the conical roller shell 1, the conductive particles in the anti-static rubber 16 will interact with the charge, causing the charge to be neutralized, thereby preventing the generation and accumulation of static electricity and making transportation smoother. At the same time, the outer side of the anti-static rubber 16 is evenly provided with patterned protrusions, which can play a role in preventing the material from slipping, making it more stable and non-slip during transportation.

[0032] Secondly, the pressure-resistant layer 17 on the inner side of the conical roller shell 1 is a carbon fiber layer to prevent the conical roller shell 1 from being aggravated by wear due to uneven force. The carbon fiber layer has extremely high specific strength and specific modulus. When bearing the same weight, the carbon fiber layer can provide better structural support and is not easy to deform, thereby maintaining the stability of the conical roller shell 1 when transporting items.
