Description

Technical Field

[0001] This invention relates to the field of cooling technology for rubber products, specifically to a high-efficiency cooling device for the production of rubber products. Background Technology

[0002] Existing methods for cooling rubber products typically involve using straight-hole water channels. However, these channels struggle to cover complex cavities, creating cooling dead zones that lead to incomplete curing or over-vulcanization, requiring repeated cooling and extending the curing cycle. Air cooling suffers from unstable airflow, resulting in slower cooling rates at the center of thicker rubber products and heat buildup in the core. Water-cooled spray cooling can cause scale-like white spots (typically composed of calcium and magnesium ions) to form on the product surface. Furthermore, excessively high spray pressure can lead to surface pitting. Liquid nitrogen cooling, on the other hand, can cause localized ultra-low temperatures, resulting in broken rubber molecular chains and microcracks.

[0003] Therefore, we propose a high-efficiency cooling device for rubber product manufacturing. Summary of the Invention

The circulation pump is installed at the top left end of the ethanol pretreatment equipment. The front end of the circulation pump is connected to the third circulation pipe. The third circulation pipe is connected to the left end of the coupling cooling component through a winding and auxiliary mechanism.

[0015] As a preferred embodiment of the high-efficiency cooling device for rubber product manufacturing according to the present invention, the winding and auxiliary mechanism includes: a limiting component;

[0016] The limiting components are installed at both ends of the inner wall of the vacuum chamber, and the winding components are installed between the limiting components. An auxiliary component is provided between the two winding components, and the auxiliary component is installed at the middle position of both ends of the limiting components.

[0017] As a preferred embodiment of the high-efficiency cooling device for rubber product manufacturing according to the present invention, the limiting component includes: a limiting plate;

[0018] The limiting plate is fixedly installed at both ends of the outer wall of the vacuum chamber. The inner wall port of the limiting plate is rotatably connected to the rotating liquid storage plate. The outer wall of the left limiting plate is equipped with a first motor. The first motor passes through the limiting plate and the rotating liquid storage plate and is connected to the center of the triangular bracket. The endpoints of the three sets of apex corners of the triangular bracket are all equipped with limiting shaft seats. The inside of the limiting shaft seat is rotatably connected to the winding assembly. The outer wall of the limiting shaft seat is equipped with a second motor.

[0019] As a preferred embodiment of the high-efficiency cooling device for rubber product manufacturing according to the present invention, the winding assembly includes: a rotating shaft seat;

[0020] The rotating shaft seat is rotatably connected inside the limiting shaft seat. The port of the rotating shaft seat is connected to the sprocket of the second motor drive end. An annular liquid guide plate is installed on the outer wall of the rotating shaft seat. The output end of the right annular liquid guide plate is connected to the first circulation pipe through the limiting plate and the rotating liquid storage plate. The output end of the left annular liquid guide plate is connected to the third circulation pipe through the limiting plate and the rotating liquid storage plate. The inner wall of the rotating shaft seat is connected to the port of the take-up roller.

[0021] As a preferred embodiment of the high-efficiency cooling device for rubber product manufacturing according to the present invention, the auxiliary component includes: a Z-shaped rotating rod;

[0022] The Z-shaped rotating rod is rotatably connected to the middle of both ends of the triangular bracket. A third motor is installed on the outer wall of the middle of both ends of the triangular bracket. The output end of the third motor is connected to the port of the Z-shaped rotating rod. The inner port of the Z-shaped rotating rod is connected to the mounting plate. The inner port of the Z-shaped rotating rod is connected to the outer wall of the mounting plate by a torsion spring.

The protrusion is spirally placed inside the spiral pipe. The spiral pipe also has an alkane capsule.

[0025] Compared with existing technologies:

[0026] By coordinating the convex pillars, alkane capsules, and circulating water flow of the coupled cooling components, the convex pillars disrupt the boundary layer of the alkane capsules, achieving instantaneous heat absorption and diffusion, rapidly suppressing local hot spots, and quickly and uniformly cooling the rubber products while preventing stress cracking caused by overcooling of the product surface.

[0027] By combining the vacuum environment created by the vacuum flash evaporation mechanism with the heated anhydrous ethanol, the low boiling point of ethanol under low pressure (e.g., the boiling point of ethanol is about 20°C at a vacuum of 5 kPa) is utilized. The latent heat of vaporization is much higher than that of water, and the heat carried away by the medium per unit mass is higher. Furthermore, the vapor condenses rapidly at the ethanol collection component, and the residual heat of the ethanol can be used in reverse to maintain the temperature stability inside the vacuum chamber, forming an energy closed loop.

[0028] By combining coupled cooling with vacuum flash evaporation, the solid-to-liquid phase transition (alkane capsule) and gas-to-liquid phase transition (ethanol flash evaporation) can be achieved simultaneously in the vacuum chamber. This allows the environment inside the vacuum chamber to change rapidly and be maintained at the corresponding temperature, thereby shortening the thermal response time and improving evaporation and condensation efficiency.

[0029] By cooperating with the winding and auxiliary mechanism, the coupling cooling component and the vacuum flash evaporation mechanism, the rubber product can be cooled from all angles at the physical level, ensuring the uniformity of cooling and avoiding microcracks caused by incomplete local curing, over-sulfurization, heat accumulation in the core and breakage of rubber molecular chains.

[0051] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0052] This invention provides a high-efficiency cooling device for rubber product manufacturing. Please refer to [link / reference]. Figures 1-19 It includes a vacuum flash evaporation mechanism 1, a coupled cooling circulation assembly 2, a winding and auxiliary mechanism 3, and a coupled cooling assembly 4;

[0053] The vacuum flash evaporation mechanism 1 is placed at the output end of the rubber product manufacturing process. It is used to perform vacuum flash evaporation on freshly produced rubber products. The vacuum flash evaporation mechanism 1 includes: a vacuum pressurization assembly 11, an ethanol pretreatment device 111, a vacuum chamber 112, a sealed chamber door 113, a drain valve 114, a pressure sensor 12, a temperature sensor 13, an ethanol collection assembly 14, a rear baffle 141, a collection box 142, a condenser plate 143, a finned heat exchanger 144, a guide plate 145, a through channel 146, a guide channel 147, and a vacuum pump assembly 15. The vacuum pressurization assembly 11, located at the output end of the rubber product manufacturing process, can perform a vacuuming operation on the internal space, controlling the air pressure within the vacuum chamber 112. The pressure is controlled at 20 kPa. The ethanol pretreatment equipment 111 is placed on the ground. The ethanol pretreatment equipment 111 contains a pump and heating equipment. The pump circulates anhydrous ethanol, and the heating equipment preheats the anhydrous ethanol inside the ethanol pretreatment equipment 111. A vacuum chamber 112 is located on top of the ethanol pretreatment equipment 111. The vacuum chamber 112, in conjunction with a vacuum pump assembly 15 and a pressure sensor 12, performs a vacuum operation to control the atmospheric pressure within a specified range. A sealing door 113 is rotatably connected to the top of the vacuum chamber 112, used to open and close the opening of the vacuum chamber 112. A drain valve 114 is located on the lower rear side of the interior of the vacuum chamber 112. The bottom of the drain valve 114 is connected to… At the output end of the ethanol pretreatment equipment 111, a drain valve 114 allows the ethanol pretreatment equipment 111 to discharge preheated anhydrous ethanol into the vacuum chamber 112. A pressure sensor 12 is installed on the upper side of the outer wall of the right end of the vacuum pressurization assembly 11, which can monitor the air pressure inside the vacuum pressurization assembly 11 in real time. A temperature sensor 13 is installed at the rear end of the pressure sensor 12, which can monitor the surface temperature of the rubber product in real time. An ethanol collection assembly 14 is installed at the rear end of the vacuum pressurization assembly 11, which can condense and collect the anhydrous ethanol vapor evaporated by the vacuum pressurization assembly 11 and recycle the collected ethanol. A rear baffle 141 is installed in the vacuum chamber. A collection box 142 is installed at the lower end of the front surface of the rear baffle 141 inside the rear end of 112. The collection box 142 collects the condensed ethanol. The right end of the collection box 142 is connected to the input end of the ethanol pretreatment equipment 111. The collected ethanol is discharged into the ethanol pretreatment equipment 111 through the collection box 142, thus achieving liquid circulation of anhydrous ethanol. A condensing plate 143 is installed on the top of the rear baffle 141, and a condensing pipe is installed at the bottom of the condensing plate 143. The condensing pipe is filled with cooling water. The input end of the condensing pipe is connected to the output end of the finned heat exchanger 144, and the output end of the condensing pipe is connected to the input end of the finned heat exchanger 144. Through the cooperation between the condensing pipe and the finned heat exchanger 144…The system enables heat exchange circulation of cooling water. Simultaneously, the condensate in the condensing pipe condenses the vaporized ethanol into water droplets. A finned heat exchanger 144 is installed at the rear end of the vacuum chamber 112. The finned heat exchanger 144 exchanges heat with the cooling water, rapidly cooling it before supplying it back into the condensing pipe. A guide plate 145 is located at the bottom of the condensing plate 143, with its right end tilted downwards. Through grooves 146 are arranged around the surface of the guide plate 145, and guide channels 147 are located between the through grooves 146. When heated anhydrous ethanol reacts with the air pressure inside the vacuum chamber 112, the boiling point of the anhydrous ethanol rapidly decreases under atmospheric pressure, causing it to vaporize quickly and produce a large amount of ethanol vapor. This ethanol vapor naturally flows upwards due to density difference, allowing it to contact the condensing plate 143 through the through grooves 146. The condensing plate 143 then condenses this large amount of ethanol vapor. The water droplets formed fall onto the surface of the guide plate 145, and are then guided through the guide channel 147 to the inside of the collection box 142 for collection. The collection box 142 then discharges the collected condensed ethanol into the ethanol pretreatment equipment 111 for secondary preheating, thereby achieving continuous flash evaporation of anhydrous ethanol. The top of the vacuum pressurization component 11 is equipped with a vacuum pump group 15. Through the cooperation of the vacuum pump group 15 and the pressure sensor 12, the air pressure in the vacuum chamber 112 is controlled at 20 kPa, so that the anhydrous ethanol evaporates in an environment of 20 kPa, thereby causing the anhydrous ethanol to instantly reach its boiling point and flash evaporation. The large amount of ethanol vapor rapidly absorbs heat from the freshly produced rubber products. The core of vacuum flash cooling is to utilize the physical property that the boiling point of a liquid decreases significantly with decreasing pressure, so that the cooling medium rapidly evaporates and flashes under low pressure, absorbing the heat of the rubber products through the latent heat of phase change, thus achieving rapid cooling.

[0054] The coupled cooling circulation assembly 2 is installed at both ends of the surface of the vacuum flash evaporation mechanism 1. The coupled cooling circulation assembly 2 is connected to the coupled cooling assembly 4 through the winding and auxiliary mechanism 3. Through the cooperation of the coupled cooling circulation assembly 2 and the coupled cooling assembly 4, it is used for coupled cooling of rubber products. The coupled cooling circulation assembly 2 includes: a filter box 21, a first circulation pipe 22, a second circulation pipe 23, a circulation pump 24, and a third circulation pipe 25. The filter box 21 is installed at the top right end of the ethanol pretreatment equipment 111. The filter box 21 is externally connected to a heat exchanger. The interior of the filter box 21 is filled with activated carbon. Through the cooperation of the filter box 21 and the heat exchanger, the water circulating in the coupled cooling assembly 4 can be filtered by activated carbon and rapidly cooled by the heat exchanger. The filter box 21 is equipped with a pushing device and a screening device, which can screen the alkane capsules 46. The screening alkane capsules 46 are discharged back to the second circulation pipe 23 through the pushing device. Therefore, the filter box 21 only filters the circulating water. The front end of the filter box 21 is connected to the first circulation pipe 22. The first circulation pipe 22 is connected to the second circulation pipe 23 through the winding and auxiliary mechanism 3. Mechanism 3 is connected to the right end of the coupling cooling assembly 4. The first circulation pipe 22 can transport the circulating water and alkane capsule 46 in the coupling cooling assembly 4 to the filter box 21 for filtration, preventing the alkane capsule 46 from breaking and causing condensation and blockage of the pipe due to contact between alkane and water. The rear end of the filter box 21 is connected to the second circulation pipe 23. The circulating water filtered by the filter box 21 moves to an external heat exchanger, exchanges heat with the heat exchanger, and then returns to the rear end of the filter box 21, where it is circulated and discharged again through the second circulation pipe 23 at the rear end of the filter box 21. The other end of the second circulation pipe 23 is connected to the rear end of the circulation pump 24. The circulation pump 24 is installed at the top left end of the ethanol pretreatment equipment 111. The circulation pump 24 can accelerate the flow of circulating water and alkane capsule 46, so that the circulating water can continuously perform coupled cooling operation on the winding and auxiliary mechanism 3. The front end of the circulation pump 24 is connected to the third circulation pipe 25. The third circulation pipe 25 is connected to the left end of the coupled cooling assembly 4 through the winding and auxiliary mechanism 3. The third circulation pipe 25 can continuously transport filtered and cooled circulating water to the coupled cooling assembly 4.

[0055] The winding and auxiliary mechanism 3 is installed inside the vacuum flash evaporation mechanism 1. The winding and auxiliary mechanism 3 is used to collect and limit the freshly produced rubber products, and works in conjunction with the vacuum flash evaporation mechanism 1 and the coupling cooling assembly 4 for dual cooling. The winding and auxiliary mechanism 3 includes: a limiting assembly 31, a limiting disc 311, a rotating liquid storage disc 312, a first motor 313, a triangular bracket 314, a limiting shaft seat 315, a second motor 316, a winding assembly 32, a rotating shaft seat 321, an annular liquid guide plate 322, a winding roller 323, an auxiliary assembly 33, a Z-shaped rotating rod 331, a third motor 332, a mounting plate 333, a torsion spring 334, and an auxiliary roller 335. The limiting assembly 31 is installed at both ends of the inner wall of the vacuum chamber 112. The device can install and limit the winding assembly 32, and can also drive the winding assembly 32 to rotate. The limiting plate 311 is fixedly installed at both ends of the outer wall of the vacuum chamber 112. The inner wall port of the limiting plate 311 is rotatably connected to the rotating liquid storage plate 312. The inner end of the rotating liquid storage plate 312 is connected to the pipe of the coupling cooling assembly 4, so that the circulating water and alkane capsule 46 in the coupling cooling assembly 4 can be transported to the outside of the limiting plate 311 through the rotating liquid storage plate 312. At the same time, by rotating the rotating liquid storage plate 312, the winding and auxiliary mechanism 3 can be rotated, preventing the pipe of the coupling cooling assembly 4 from getting tangled with the rotation of the winding and auxiliary mechanism 3. The outer wall of the left limiting plate 311 is equipped with a first motor 313. Motor 313 passes through the limiting plate 311 and the rotating liquid storage plate 312 and is connected to the center of the triangular bracket 314. Driven by the first motor 313, the triangular bracket 314 can rotate, thereby causing the triangular bracket 314 to drive the winding assembly 32 and the auxiliary assembly 33 to rotate. This causes the rubber product that is wound and limited by the winding assembly 32 and the auxiliary assembly 33 to rotate accordingly. Thus, when the ethanol vapor flows upward, it can contact the rubber product at all angles, allowing the rubber product to cool rapidly while ensuring uniform cooling. Each of the three apex points of the triangular bracket 314 is equipped with a limiting bearing 315. The winding assembly 32 is rotatably connected inside the limiting bearing 315, allowing the winding assembly 32 to be controlled through the limiting bearing 315. The system is installed and positioned, and simultaneously limits and guides the rotation of the winding assembly 32. A second motor 316 is mounted on the outer wall of the limiting shaft seat 315. The second motor 316 is connected to the winding assemblies 32 within the three sets of limiting shaft seats 315 via sprockets and chains. The sprockets and chains are located inside the triangular bracket 314, which limits their movement. When the second motor 316 is driven, it can drive the three sets of winding assemblies 32 to rotate simultaneously, thereby achieving the transmission and winding of the rubber product. The winding assemblies 32 are installed between the limiting assemblies 31, and they can receive and wind up the newly produced rubber product. The rotating shaft seat 321 is rotatably connected inside the limiting shaft seat 315.The port of the rotating shaft seat 321 is connected to the sprocket at the drive end of the second motor 316. Driven by the second motor 316, the rotating shaft seat 321 can rotate, thereby causing the rotating shaft seat 321 to drive the take-up roller 323 to rotate. An annular liquid guide plate 322 is installed on the outer wall of the rotating shaft seat 321. Since the inner wall of the annular liquid guide plate 322 is in contact with the outer wall of the inner bearing of the rotating shaft seat 321, the rotation of the rotating shaft seat 321 can only drive the take-up roller 323 to rotate, thus preventing the rotation of the annular liquid guide plate 322 from causing pipe entanglement or damage. The output end of the right annular liquid guide plate 322 is connected to the first circulating... The annular pipes 22 are interconnected. The output end of the left-end annular liquid guide plate 322 is interconnected with the third circulation pipe 25 through the limiting plate 311 and the rotating liquid storage plate 312. The annular liquid guide plate 322 enables the coupling cooling assembly 4 and the coupling cooling circulation assembly 2 to circulate. The inner wall of the rotating shaft seat 321 is connected to the port of the take-up roller 323, so that the rotation of the second motor 316 can drive the take-up roller 323 to rotate, so that the take-up roller 323 can drive and take up the rubber product. An auxiliary assembly 33 is provided between the two sets of take-up assemblies 32. The auxiliary assembly 33 is installed at the middle position of both ends of the limiting assembly 31. The auxiliary assembly 33 can assist in the receiving of the rubber product. The auxiliary roller 335 assists in the transfer and clamps and limits the transferred rubber products, ensuring that the rubber products are wound between the three sets of winding components 32. A Z-shaped rotating rod 331 is rotatably connected to the middle of both ends of a triangular bracket 314. A third motor 332 is mounted on the outer wall of the middle of both ends of the triangular bracket 314. The output end of the third motor 332 is connected to the port of the Z-shaped rotating rod 331. Driven by the third motor 332, the Z-shaped rotating rod 331 can be rotated. The inner port of the Z-shaped rotating rod 331 is connected to the mounting plate 333. The inner port of the Z-shaped rotating rod 331 and the outer wall of the mounting plate 333 are connected by a torsion spring 334. Thus, when the auxiliary roller 335 contacts the winding roller 323... The auxiliary roller 335 changes angle with the mounting plate 333 and works in conjunction with the take-up roller 323 to clamp and limit the movement. When the auxiliary roller 335 leaves the take-up roller 323, it returns to its initial position. This allows the auxiliary roller 335 to adapt to and cooperate with the three sets of take-up rollers 323. Two sets of auxiliary rollers 335 are rotatably connected between the two sets of mounting plates 333. Through the gap between the two sets of auxiliary rollers 335, the rubber products received by the take-up roller 323 can be transferred. When the two sets of auxiliary rollers 335 contact the take-up roller 323, they can press and fix the rubber products during winding, preventing them from falling off.

[0056] The coupling cooling assembly 4 is installed inside the winding and auxiliary mechanism 3. It dynamically cools the surface of the rubber product wound by the winding and auxiliary mechanism 3. The coupling cooling assembly 4 includes: a limiting ring 41, a through hole 42, a heat-conducting rod 43, a spiral pipe 44, a protrusion 45, and an alkane capsule 46. The limiting ring 41 is installed at both ends inside the winding roller 323. The bottom of the limiting ring 41 has a through hole 42, through which circulating water and the alkane capsule 46 inside the spiral pipe 44 can be discharged. Since the through hole 42 is wrapped by the rotating shaft seat 321, a first groove is provided at the left side of the rotating shaft seat 321, and a second groove is provided on one side of the inner wall of the annular liquid guide plate 322. The annular liquid guide plate 322 and the rotating shaft seat 321... The grooves on the left are connected by a sealing ring. Therefore, the circulating water and alkane capsules 46 inside the spiral pipe 44 are discharged through the through hole 42 to the rotating shaft seat 321 and the annular guide plate 322, and then transported to the first circulation pipe 22 through the annular guide plate 322, thereby realizing the circulation flow of the circulating water and alkane capsules 46. A heat-conducting rod 43 is installed inside the limiting ring 41. The heat-conducting rod 43 is installed inside the take-up roller 323. The spiral pipe 44 is installed on the outer wall of the heat-conducting rod 43. Since both the take-up roller 323 and the heat-conducting rod 43 are made of heat-conducting materials, when the spiral pipe 44 transports the circulating water and alkane capsules 46, the circulating water quickly transfers the cooled temperature to the take-up roller 323, so that the temperature of the outer wall of the take-up roller 323 is similar to that of the circulating water. Since the outer wall temperature of the water is relatively uniform, the winding roller 323 can rapidly cool the inner wall of the rubber product and make the cooling relatively uniform when it rotates to drive the rubber product. The spiral pipe 44 has protruding pillars 45 arranged spirally inside. The spiral pipe 44 also contains alkane capsules 46, which flow with the circulating water. The inner layer of the alkane capsule 46 is flexible PMMA, and the outer layer is rigid SiO2. Stress buffering is achieved through interfacial chemical bonding of Si-OC. When the phase change microcapsules flow through the straight channel with the water, a stagnant boundary layer forms on the surface of the microcapsules due to fluid viscosity. The thermal conductivity of this boundary layer is only 1 / 3 that of water, thus increasing the thermal resistance between the microcapsules and the water. The flow of alkane capsules 46 comes into contact with protrusions 45, which periodically peel away the stagnant layer on the surface of the microcapsules through the Karman vortex street effect, increasing the effective heat transfer area. The lateral velocity component generated by the protrusions 45 drives the microcapsules to rotate, accelerating the phase change mixing of the internal alkanes and improving latent heat release efficiency. When the temperature of the circulating water is diluted by the take-up roller 323 and the rubber products, the alkane capsules 46 react with the temperature in the circulating water. At this time, the alkanes inside the alkane capsules 46 absorb heat and melt, changing from a solid to a liquid, and absorb heat from the circulating water, giving the circulating water a cooling temperature again. The take-up roller 323 continuously and uniformly cools the rubber products. When the alkane capsules 46 are discharged through the coupled cooling circulation assembly 2...The alkane capsule 46 is cooled again by circulating water through a heat exchanger, causing the alkanes inside to change from liquid to solid again. This allows the alkane capsule 46 to quickly absorb and store heat when the rubber is at high temperature, preventing a sudden rise in the mold surface temperature. During the later stages of cooling, the alkane capsule 46 releases heat as it solidifies, preventing stress cracking caused by excessive cooling of the product surface.

[0057] In practical use, those skilled in the art add anhydrous ethanol to the ethanol pretreatment device 111. The ethanol pretreatment device 111 preheats the anhydrous ethanol to below its normal boiling point to prevent it from boiling prematurely. The preheated anhydrous ethanol is then discharged into the vacuum chamber 112 through the drain valve 114. The newly produced high-temperature rubber product is received and wound up by the winding and auxiliary mechanism 3. The sealed door 113 of the vacuum chamber 112 is then closed. Cooling is then performed by activating the coupled cooling circulation component 2 and the vacuum pump group 15, which evacuates the vacuum chamber 112 to maintain the atmospheric pressure inside the vacuum chamber 112 at approximately 20 kPa. At this point, the anhydrous ethanol and the vacuum... When the gas pressure inside chamber 112 reacts, the boiling point of anhydrous ethanol drops rapidly under atmospheric pressure, causing it to vaporize quickly and generate a large amount of ethanol vapor. This flash evaporation process rapidly absorbs heat from the surface of the rubber product and flows to the ethanol collection assembly 14 for condensation. At this time, the winding and auxiliary mechanism 3 drives the winding limiter of the rubber product to rotate, ensuring that the large amount of ethanol vapor cools the rubber product evenly. Simultaneously, the coupled cooling circulation assembly 2 cools the winding roller 323 through circulating water and alkane capsule 46, so that the winding roller 323 uniformly cools the inner wall of the rubber product while driving the winding rubber product. Under the dual cooling of vacuum flash evaporation and coupled cooling, the rubber product can be cooled quickly.
