Description

Technical Field

[0001] This utility model relates to the field of cooling roller technology, and in particular to a shaping roller for rapid cooling of elastomeric materials. Background Technology

[0002] A roller is a hollow cylindrical part supported by shafts at both ends and driven by a drive device to rotate. Its components are smooth, textured or coated cylindrical surfaces adapted to different process requirements. The two ends are fixed by bearings to ensure stability during high-speed rotation. The hollow internal structure allows heating or cooling media to be introduced into the roller, making its surface a huge heat exchanger, thus becoming a cooling and shaping roller.

[0003] Elastic material shaping rollers are core functional roller equipment specifically used in the processing of elastic materials to achieve material shape fixation and dimensional stability through cooling. By rapidly cooling, they prevent material deformation due to elastic recovery, ensuring product dimensional stability and surface quality, quickly fixing the material shape, reducing elastic recovery, and improving product quality and production efficiency. However, in traditional flow channel or straight channel designs, there is a temperature gradient of the cooling medium from the inlet to the outlet, resulting in a significant temperature difference between the two ends of the roller surface. This can easily lead to uneven shrinkage and warping at the edges of the elastomeric material, resulting in uneven cooling and low efficiency. Therefore, a shaping roller for rapid cooling of elastomeric materials is proposed to solve the above problems. Utility Model Content

[0032] Reference Figure 3 and Figure 4 An embodiment of this utility model provides a shaping roller for rapid cooling of elastomeric material, comprising an inner liner 1 and two bases 7. A roller shell 2 is fixedly connected to the outer wall of the inner liner 1. A cooling mechanism 3 is provided on the outer wall of the inner liner 1 for cooling and shaping. A water injection mechanism 4 is provided on the outer wall of the roller shell 2 for cleaning. A rotating mechanism 5 is provided on the outer wall of the roller shell 2 for rotating. A sealing mechanism 6 is provided on the outside of the roller shell 2 for sealing.

[0033] The cooling mechanism 3 includes a shaft 301, the outer wall of which is fixedly connected to the inner wall of the inner liner 1. The shaft 301 is responsible for the rotation and cooling of the entire device. Water inlets 302 and outlets 303 are provided at both ends of the shaft 301. The water inlets 302 and outlets 303 are mirror images of each other, i.e., the left end has inlet at the top and outlet at the bottom, and the right end has outlet at the top and inlet at the bottom. Two diverter plates 304 are fixedly connected to the top of the shaft 301. The diverter plates 304 serve to divert the coolant, supplying one portion to the cooling water pipe 305 and the other portion to the flow tube 3092. Multiple cooling water pipes 305 are fixedly connected to the top of the inner liner 1. The cooling water pipes 305 are responsible for outputting coolant evenly and orderly. Multiple through holes 306 are opened on the top of the outer wall of the inner liner 1. The through holes 306 are connected to the cooling water pipes 305. A first guide plate 307 and a second guide plate 308 are fixedly connected to the outer wall of the inner liner 1. The first guide plate 307 and the second guide plate 308 form two spiral channels. Coolant is injected from the opposite end of each channel to dissipate heat evenly to the inner liner 1. A heat conduction component 309 is provided on the outer wall of the inner liner 1 to improve heat dissipation efficiency.

[0034] The heat conduction component 309 includes multiple heat transfer plates 3091. The adjacent sides of the multiple heat transfer plates 3091 are fixedly connected to the outer wall of the inner liner 1. The heat transfer plates 3091 themselves are good heat conduction materials, which can quickly transfer internal heat and expand the contact area with the coolant. Two flow tubes 3092 are opened on the inner wall of the shaft 301. The flow tubes 3092 are located inside, which reduce the temperature of the contact surface of the shaft 301 and play a certain cooling role.

[0035] Specifically, the shaft 301 is responsible for the overall rotation and cooling of the device. The inlet 302 and outlet 303 are mirror images of each other, with the left end receiving coolant from the top and the right end receiving coolant from the bottom. The diverter plate 304 acts as a diverter, supplying part of the coolant to the cooling water pipe 305 and the other part to the flow tube 3092. The cooling water pipe 305 is responsible for the uniform and orderly output of coolant. The through hole 306 connects to the cooling water pipe 305. The first guide plate 307 and the second guide plate 308 form two spiral channels. Coolant is injected from the opposite end of each channel to uniformly dissipate heat from the inner tank 1. The heat transfer plate 3091 is itself a good thermal conductive material, which quickly transfers internal heat and expands the contact area with the coolant. The flow tube 3092 is located inside, reducing the temperature of the contact surface of the shaft 301 and playing a certain cooling role. The dual-inlet and dual-outlet spiral structure solves the problem of uneven axial temperature difference, accelerates internal cooling, and improves cooling efficiency.

[0036] Reference Figure 2 and Figure 5The water injection mechanism 4 includes two outer rings 401. The outer walls of both outer rings 401 are fixedly connected to the outer wall of the roller shell 2. The outer rings 401 are used to enhance the strength of the roller shell 2 and also connect to the connecting blocks 402. Two connecting blocks 402 are fixedly connected to the bottom end of the roller shell 2. The connecting blocks 402 penetrate the surface of the roller shell 2. Water injection pipes 403 are fixedly connected to the inner walls of both connecting blocks 402. The water injection pipes 403 connect the inside and outside of the roller shell 2. The bottom ends of both water injection pipes 403 are fixedly connected to a control device. Valve 404, the control valve 404 can be used to prevent coolant from flowing out through water injection pipe 403 when the cooling mechanism 3 is running, and can also be used to control the switch and flow rate when cleaning fluid is introduced. The outer walls of the two water injection pipes 403 are fixedly connected with sealing strips 405. The sealing strips 405 are located at the connection between the water injection pipes 403 and the control valve 404 and are used to seal. The outer walls of the two control valves 404 are provided with connecting components 406. The connecting components 406 are used to connect external cleaning components.

[0037] The connecting assembly 406 includes two spiral ports 4061. The tops of the two spiral ports 4061 are fixedly connected to the bottom of the control valve 404. The spiral ports 4061 can be spirally connected to external pipes. The outer walls of the two spiral ports 4061 are threaded with retaining rings 4062. The retaining rings 4062 are used for fixed connection and also play a certain sealing role.

[0038] Specifically, the outer ring 401 is used to enhance the strength of the roller shell 2 and connects the connecting block 402. The connecting block 402 penetrates the surface of the roller shell 2 and is located in the middle. Water is injected from here for cleaning, and water can be discharged from both ends, making cleaning quick and effective. The water injection pipe 403 connects the inside and outside of the roller shell 2. The control valve 404 can be used to prevent coolant from flowing out through the water injection pipe 403 when the cooling mechanism 3 is running, and can also be used to control the switch and flow rate when cleaning fluid is introduced. The sealing strip 405 is located at the connection between the water injection pipe 403 and the control valve 404 and is used for sealing. The spiral pipe port 4061 can be spirally connected to the external pipe. The fixing ring 4062 is used for fixed connection and also plays a certain sealing role, improving the service life of the device and reducing the wear of the cooling components.

[0039] Reference Figure 1 , Figure 4 and Figure 5 The rotating mechanism 5 includes two shaft heads 501. The inner walls of the two shaft heads 501 are fixedly connected to the left and right ends of the shaft 301. The shaft heads 501 are symmetrically distributed at both ends of the shaft 301. They are integrally forged or welded with the roller body to ensure connection strength. The outer walls of the two shaft heads 501 are provided with connection holes 502 for connecting with transmission components.

[0040] The sealing mechanism 6 includes two end plates 601. The adjacent sides of the two end plates 601 are fixedly connected to the left and right ends of the roller shell 2. The end plates 601 are used to seal the cavity of the inner liner 1 of the roller to prevent the elastic material from flowing out. The opposite sides of the two end plates 601 are fixedly connected to a sealing ring 602, which plays a sealing role.

[0041] Support plates 8 are fixedly connected to the top of both bases 7. The support plates 8 serve as support and connection and have high strength. Bearings 9 are fixedly connected to the inner walls of both support plates 8. The bearings 9 support the shaft 301, reduce friction, and ensure its smooth and stable rotation. Pads 10 are fixedly connected to the bottom of both bases 7. Pads 10 increase the friction with the ground and reduce the occurrence of displacement. Multiple reinforcing ribs 11 are fixedly connected to the top of both bases 7. The reinforcing ribs 11 strengthen the connection strength between the support plates 8 and the bases 7.

[0042] Specifically, the shaft heads 501 are symmetrically distributed at both ends of the shaft core 301, and are integrally forged or welded with the roller body to ensure connection strength. The connecting hole 502 is used to connect with the transmission component. The end plate 601 is used to seal the cavity of the roller inner liner 1 to prevent the elastic material from flowing out. The sealing ring 602 plays a sealing role. The support plate 8 plays a supporting connection role and has high strength. The bearing 9 is used to support the shaft core 301, reduce friction, and ensure its smooth and stable rotation. The pad plate 10 increases the friction with the ground and reduces the occurrence of deviation. The reinforcing rib 11 strengthens the connection strength between the support plate 8 and the base 7, ensuring that the device can rotate smoothly, cool and solidify, and enhance the stability of the device.

[0043] Working principle: The shaft 301 is responsible for the rotation and cooling of the entire device. Coolant is introduced into the inlets 302 at both ends, and the flow is divided by the diverter plate 304. Part of the coolant is supplied to the cooling water pipe 305, which outputs the coolant evenly and orderly. It enters two spiral channels formed by the first guide plate 307 and the second guide plate 308 to dissipate heat evenly to the inner tank 1. The other part of the coolant is supplied to the flow tube 3092 to reduce the temperature of the contact surface of the shaft 301, which plays a certain role in cooling. Finally, it is discharged through the outlet 303. The inlet and outlet are mirrored, that is, the left end is inlet at the top and outlet at the bottom, and the right end is outlet at the top and inlet at the bottom, which is conducive to uniform heat dissipation. The inlet hole 306 connects to the cooling water pipe 305. The heat transfer plate 3091 itself is a good thermal conductive material, which quickly transfers internal heat and expands the contact area with the coolant. The double-inlet spiral structure solves the problem of uneven axial temperature difference, accelerates internal cooling, and improves cooling efficiency.

[0044] Furthermore, prolonged use leads to scale and impurities clogging the cooling mechanism 3. The spiral port 4061 is spirally connected to the external cleaning pipe. The control valve 404 is opened to control the flow rate. The cleaning fluid passes through the middle of the roller shell 2 and exits from both ends, providing rapid and effective cleaning. The outer ring 401 enhances the strength of the roller shell 2 and connects and fixes the connecting block 402. The control valve 404 also prevents coolant from flowing out through the water injection pipe 403 during the operation of the cooling mechanism 3. The sealing strip 405 is located at the connection between the water injection pipe 403 and the control valve 404, providing a seal. The fixing ring 4062 securely connects the spiral port 4061 to the external cleaning pipe and also provides a certain degree of sealing, improving the service life of the device and reducing wear on the cooling components.
