AI Technical Summary
When existing cooling rollers are used to cool synthetic leather at high temperatures, the circulating water pipes are prone to softening or sticking to the inner wall of the cooling rollers, affecting the normal use of the cooling rollers and the cooling effect.
The system uses a heat-conducting ring and coolant to absorb the heat from the cooling roller body and transfer it to the circulating water pipe through the heat-conducting ring. Combined with the transmission mechanism, the cooling roller rotates evenly to improve the cooling effect and prevent high temperature from being directly transferred to the outer wall of the water pipe.
This effectively avoids the softening or sticking problems of the circulating water pipes, improves the service life and cooling effect of the cooling roller, and ensures the stability of the cooling roller and uniform cooling of the synthetic leather.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling roller technology, and specifically to a cooling roller structure. Background Technology
[0002] Synthetic leather is a plastic product that mimics natural leather. Its high degree of imitation makes it widely used in the manufacture of various shoes, bags, balls, etc. Cooling rollers are common components in synthetic leather production equipment, mainly used to cool the synthetic leather.
[0003] A search revealed an invention patent with publication number CN108086001A, which discloses a cooling roller used in a synthetic leather cooling machine. The roller includes a roller and cooling water pipes. A chamber is formed axially within the roller, and the cooling water pipes are fixed to the inner wall of the chamber. The cooling water pipes are arranged in a meandering pattern between the first and second ends of the chamber and extend circumferentially along the inner wall of the chamber. The inlet end of the cooling water pipe passes through the center of the first end of the roller, and the outlet end passes through the center of the second end of the roller. Cooling water flows from the first end of the chamber to the second end and then back to the first end within the cooling water pipes, maintaining a consistent temperature at both ends of the roller. This avoids the problem of deformation and wrinkling of the synthetic leather due to uneven cooling, thus improving the quality of the synthetic leather product.
[0004] Although the aforementioned patent describes a process where cooling water flows from the first end of the chamber to the second end and then back to the first end within the cooling water pipe, maintaining a consistent temperature at both ends of the roller and preventing deformation and wrinkling of the synthetic leather due to uneven cooling, thus improving the quality of the synthetic leather product, the surface temperature of the synthetic leather after production is 80°-150°. Furthermore, when the cooling roller cools the synthetic leather, it directly contacts the surface of the synthetic leather to absorb heat. Therefore, the internal cooling circulation pipes are directly affected by the high temperature transmitted by the cooling roller, causing the circulation pipes to soften or stick to the inner wall of the cooling roller, thereby affecting the normal use of the cooling roller.
[0005] Therefore, it is necessary to propose a cooling roller structure to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a cooling roller structure that, through the cooperation of the internal parts of the cooling mechanism, facilitates the absorption and cooling of the heat transferred by the cooling roller body by the coolant, and then transfers the cooled heat back to the circulating water pipe through the heat conduction ring. This solves the problem in the prior art where high temperature is directly transferred to the outer wall of the circulating water pipe through the cooling roller body, causing the circulating water pipe to soften or stick to the inner wall of the cooling roller body.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a cooling roller structure, comprising a cooling roller body, support frames sleeved on both sides of the cooling roller body, a cooling mechanism mechanically connected to both sides of the outer wall of the cooling roller body and extending into the interior of the cooling roller body, and a transmission mechanism installed on both sides of the outer wall of the cooling roller body and sleeved with the outer wall of the cooling mechanism and rotatably connected to the interior of the support frame;
[0008] The cooling mechanism includes a heat-conducting ring, which is installed on the inner wall of the cooling roller body. Multiple support columns are mechanically fixed between the outer wall of the heat-conducting ring and the inner wall of the cooling roller body, and are distributed in a ring on the outer wall of the heat-conducting ring. Coolant is filled between the multiple support columns and is located between the outer wall of the heat-conducting ring and the inner wall of the cooling roller body.
[0009] The transmission mechanism includes a support shaft, which is mechanically fixed to both sides of the outer wall of the cooling roller body and rotatably connected to the support frame via bearings. A connecting gear is mechanically sleeved and fixed to the outer wall of the support shaft and rotatably connected to the inside of the support frame. A servo motor is fixed to the outer wall of the support frame by bolts and is located above the connecting gear. The output end of the servo motor is rotatably connected to a transmission gear via a coupling and is located inside the support frame.
[0010] Preferably, the cooling mechanism further includes a water inlet pipe, which is sealed to the left side of the cooling roller body and extends through the support shaft to the interior of the cooling roller body. A water outlet pipe is sealed to the right side of the cooling roller body and extends through the support shaft to the interior of the cooling roller body. A circulating water pipe is sealed between the water inlet pipe and the water outlet pipe and fits against the inner wall of the heat-conducting ring.
[0011] Preferably, a circulating water tank is installed at the bottom of the plurality of support frames, and a water pump and a refrigeration device are installed on one side of the circulating water tank.
[0012] Preferably, the plurality of connecting gears mesh with each other through tooth grooves, and the connecting gears and the transmission gears mesh with each other through tooth grooves.
[0013] Preferably, the support frame has a transmission groove inside that matches the transmission gear and the connecting gear, and the support shaft is rotatably sleeved with the outer wall of the water inlet pipe and the water outlet pipe.
[0014] Preferably, the heat-conducting ring and support column are made of heat-conducting metal sheets, the coolant is made of heat-conducting oil, and the circulating water pipes are spirally distributed on the inner wall of the cooling roller body, with a spiral interval of 3mm between the circulating water pipes.
[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0016] By starting the servo motor, the servo motor drives the transmission gear to rotate. The rotation of the transmission gear drives the connecting gear to rotate through the tooth groove. The rotation of the connecting gear drives another connecting gear to rotate through the tooth block. The rotation of the connecting gear drives the support shaft to rotate on the support frame, thereby driving the cooling roller body to rotate. The rotation of the cooling roller body makes the outer wall more evenly contact the outer wall of the synthetic leather, improving the stability of cooling, and completing the traction and transportation of the synthetic leather.
[0017] As the cooling roller rotates, its outer wall comes into contact with the outer wall of the synthetic leather. Through heat transfer, the coolant absorbs heat and cools the outer wall of the synthetic leather. Simultaneously, the heat absorbed by the coolant is transferred to the circulating water pipe through the heat-conducting ring. The low-temperature cooling water in the circulating water pipe absorbs heat and cools the heat absorbed by the heat-conducting ring. At the same time, the cooling water circulates within the circulating water pipe through the inlet and outlet pipes, effectively cooling the heat absorbed by the heat-conducting ring. This avoids the problem of high temperature being directly transferred from the cooling roller to the outer wall of the circulating water pipe, causing the circulating water pipe to soften or stick to the inner wall of the cooling roller, thereby improving the service life of the cooling roller and enhancing its cooling effect.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0027] This utility model provides, for example Figure 1-5 The cooling roller structure shown includes a cooling roller body 1, with support frames 101 sleeved on both sides of the cooling roller body 1. Cooling mechanisms 2 are mechanically connected to both sides of the outer wall of the cooling roller body 1 and extend into the interior of the cooling roller body 1. Transmission mechanisms 3 are installed on both sides of the outer wall of the cooling roller body 1 and are sleeved with the outer wall of the cooling mechanism 2 and rotatably connected to the interior of the support frames 101.
[0028] The cooling mechanism 2 includes a heat-conducting ring 204, which is installed on the inner wall of the cooling roller body 1. A plurality of support columns 206 are mechanically fixed between the outer wall of the heat-conducting ring 204 and the inner wall of the cooling roller body 1, and are distributed in a ring on the outer wall of the heat-conducting ring 204. Coolant 205 is filled between the plurality of support columns 206 and is located between the outer wall of the heat-conducting ring 204 and the inner wall of the cooling roller body 1.
[0029] The transmission mechanism 3 includes a support shaft 301, which is mechanically fixed to both sides of the outer wall of the cooling roller body 1 and rotatably connected to the support frame 101 via bearings. A connecting gear 302 is mechanically sleeved and fixed to the outer wall of the support shaft 301 and rotatably connected to the inside of the support frame 101. A servo motor 303 is fixed to the outer wall of the support frame 101 by bolts and is located above the connecting gear 302. The output end of the servo motor 303 is rotatably connected to a transmission gear 304 via a coupling and is located inside the support frame 101.
[0030] Through the cooperation of the internal parts of the cooling mechanism 2, the coolant 205 first absorbs and cools the heat transferred from the cooling roller body 1, and then transfers the cooled heat back to the circulating water pipe 203 through the heat conduction ring 204. This avoids the problem of high temperature being directly transferred from the cooling roller body 1 to the outer wall of the circulating water pipe 203, causing the circulating water pipe 203 to soften or stick to the inner wall of the cooling roller body 1. Through the cooperation of the internal parts of the transmission mechanism 3, the connecting gears 302 mesh with each other to drive the cooling roller body 1 to rotate, so that the cooling roller body 1 can complete the traction and transportation of the synthetic leather. At the same time, the rotation of the cooling roller body 1 makes the outer wall of the cooling roller body 1 contact the outer wall of the synthetic leather more evenly, improving the stability of cooling.
[0031] Refer to the instruction manual appendix Figure 1-5 The cooling mechanism 2 also includes a water inlet pipe 201, which is sealed to the left side of the cooling roller body 1 and passes through the support shaft 301 to the interior of the cooling roller body 1. A water outlet pipe 202 is sealed to the right side of the cooling roller body 1 and passes through the support shaft 301 to the interior of the cooling roller body 1. A circulating water pipe 203 is sealed between the water inlet pipe 201 and the water outlet pipe 202 and fits against the inner wall of the heat conduction ring 204. Through the mutual cooperation between the internal parts of the cooling mechanism 2, the service life of the circulating water pipe 203 can be improved.
[0032] Refer to the instruction manual appendix Figure 1-5 Multiple support frames 101 are equipped with circulating water tanks at their bottom ends, and water pumps and refrigeration equipment are installed on one side of the circulating water tanks. By having multiple support frames 101 equipped with circulating water tanks at their bottom ends, and water pumps and refrigeration equipment installed on one side of the circulating water tanks, the temperature of the cooling water can be effectively reduced, thereby improving the cooling effect of the cooling roller body 1.
[0033] Refer to the instruction manual appendix Figure 1-5 Multiple connecting gears 302 mesh with each other through tooth grooves. The connecting gears 302 and the transmission gears 304 mesh with each other through tooth grooves. The meshing of multiple connecting gears 302 with the transmission gears 304 facilitates the rotation of the connecting gears 302 to drive the cooling roller body 1 to rotate.
[0034] Refer to the instruction manual appendix Figure 1-5 The support frame 101 has a transmission groove inside that matches the transmission gear 304 and the connecting gear 302. The support shaft 301 is rotatably sleeved with the outer wall of the water inlet pipe 201 and the water outlet pipe 202. The rotatable sleeve of the support shaft 301 with the outer wall of the water inlet pipe 201 and the water outlet pipe 202 facilitates the rotation of the support shaft 301 on the support frame 101, but prevents the water inlet pipe 201 and the water outlet pipe 202 from rotating.
[0035] Refer to the instruction manual appendix Figure 1-5 The heat-conducting ring 204 and the support column 206 are made of heat-conducting metal sheets, and the coolant 205 is made of heat-conducting oil. The circulating water pipes 203 are spirally distributed on the inner wall of the cooling roller body 1, and the spiral interval of the circulating water pipes 203 is 3mm. The heat-conducting ring 204 and the support column 206 are made of heat-conducting metal sheets, and the coolant 205 is made of heat-conducting oil. This allows the coolant 205 to absorb the heat from the surface of the cooling roller body 1 and transfer it to the inner wall of the cooling roller body 1 through the heat-conducting ring 204, which facilitates secondary cooling by the circulating water pipes 203.
[0036] The working principle of this practical application is as follows:
[0037] Refer to the instruction manual appendix Figure 1-5 By starting the servo motor 303, the servo motor 303 drives the transmission gear 304 to rotate. The rotation of the transmission gear 304 drives the connecting gear 302 to rotate through the tooth groove. The rotation of the connecting gear 302 drives another connecting gear 302 to rotate through the tooth block. The rotation of the connecting gear 302 drives the support shaft 301 to rotate on the support frame 101, thereby driving the cooling roller body 1 to rotate. The rotation of the cooling roller body 1 makes the outer wall more evenly contact the outer wall of the synthetic leather, improving the stability of cooling, and completing the traction and transportation of the synthetic leather.
[0038] Refer to the instruction manual appendix Figure 1-5 As the cooling roller body 1 rotates, its outer wall comes into contact with the outer wall of the synthetic leather. Through heat transfer, the coolant 205 absorbs heat to cool the outer wall of the synthetic leather. At the same time, the heat absorbed by the coolant 205 is transferred to the circulating water pipe 203 through the heat-conducting ring 204. The low-temperature cooling water in the circulating water pipe 203 absorbs heat to cool the heat absorbed by the heat-conducting ring 204. Meanwhile, the cooling water circulates inside the circulating water pipe 203 through the inlet pipe 201 and the outlet pipe 202, which effectively cools the heat absorbed by the heat-conducting ring 204. This avoids the problem of high temperature being directly transferred from the cooling roller body 1 to the outer wall of the circulating water pipe 203, causing the circulating water pipe 203 to soften or stick to the inner wall of the cooling roller body 1. This improves the service life of the cooling roller body 1 and enhances its cooling effect.
