Description

Technical Field

[0001] This invention relates to the field of tire processing, and in particular to a rubber cooling device based on compressor heat exchange. Background Technology

[0002] The rubber compound used to produce tire treads is hot-extruded into continuous strips. After being soaked in cooling water to lower the temperature to a suitable level, it is then cut into specified lengths by a cutting device downstream of the production line, thus forming a semi-finished product in the tire production process.

[0003] Currently, most existing cooling devices use a submerged cooling pool method, which involves installing drive rollers at both ends of the cooling pool, with a chain conveyor belt fitted onto the two drive rollers. The two ends of the chain conveyor belt extend above the water surface, while the rest is submerged in the water. This method is used to cool the rubber material while it is being transported, resulting in relatively high initial efficiency.

[0004] However, as the usage time increases, the rubber compound releases a large amount of heat into the cooling water during the cooling process. This heat is difficult to dissipate through natural heat dissipation, which causes the cooling water temperature to rise and the cooling effect to deteriorate. If it is to be used continuously, the rubber compound needs to be immersed in the cooling water for a long time, increasing the length of the cooling pool. This requires a large amount of water resources and also causes problems such as a longer production line and a larger equipment footprint. Summary of the Invention

One end of the second horizontal pipe is connected to the end of the second solenoid valve pipe away from the circulating cold water tank or the end of the first solenoid valve pipe away from the circulating cold water tank.

[0015] Preferably, the guide pipe is inclined, and the output direction of the open port of the guide pipe is towards the bottom inner wall of the first cooling water tank or the bottom inner wall of the second cooling water tank.

[0016] Preferably, a semi-cylindrical groove is provided at the bottom of the other side of the first cooling water tank and the bottom of the other side of the second cooling water tank, and a right-angle tube is fixed at the front end of the other side of the first cooling water tank and the front end of the other side of the second cooling water tank.

[0020] In summary, the present invention has the following beneficial effects: 1. By combining the compressor refrigeration system with the circulating cold water tank, water pump, first solenoid valve tube, second solenoid valve tube, and two return solenoid valve tubes to form a pumping circulation device, the cooling water inside the first and second cooling water tanks can be automatically cooled and circulated. This allows the first and second cooling water tanks to maintain a high-efficiency cooling effect on the rubber strip even with a shorter length, reducing the overall footprint of the device and saving water resources.

[0021] 2. By using composite flow guide pipes, the cooling water is guided synchronously over a large area, which improves the uniformity of cooling water circulation and replacement, thereby avoiding the formation of temperature difference zones in the first or second cooling water tank during the cooling water circulation process and improving the cooling effect on the rubber strip.

[0022] 3. During the cooling water replacement process, the two composite guide pipes inside the device ensure their own output while using the inclined water flow they generate to push the plastic particles deposited on the bottom inner wall of the first or second cooling water tank to the corresponding semi-cylindrical groove. This achieves automated cleaning and collection of plastic particles, thereby creating favorable conditions for subsequent plastic recycling.

[0023] 4. The first servo motor can be periodically started and stopped without shutting down the entire system. When the first servo motor is turned on, its output drives the corresponding screw rod to rotate synchronously. Under the linkage of the synchronous belt, the other screw rod will also rotate synchronously. Then, the two screw rods will force the plastic particles in the two semi-cylindrical slots and a portion of the cooling water through the two right-angle tubes to the annular space formed by the transparent sleeve and the inverted cone in the two composite collection components. When the first servo motor is turned off, the screw rods stop screw conveying, the cooling water flows back under gravity, and the plastic particles will remain in the annular space due to the filtration of the filter screen. This process can be repeated to achieve automatic recycling of plastic particles inside the first and second cooling water tanks without shutting down the entire system. Attached Figure Description

[0026] The technical solution of the present invention will be clearly and completely described below with reference to preferred embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figures 1-3A rubber cooling device based on compressor heat exchange includes a circulating cold water tank 1 and a compressor refrigeration system. The refrigeration end of the compressor refrigeration system is installed inside the circulating cold water tank 1. The compressor refrigeration system includes a compressor 2, a condenser 3, a submerged coil evaporator 4, and an expansion valve. Pipes are installed between the compressor 2 and the submerged coil evaporator 4, between the compressor 2 and the condenser 3, between the condenser 3 and the expansion valve, and between the expansion valve and the submerged coil evaporator 4. The submerged coil evaporator 4, as the refrigeration end of the compressor refrigeration system, is installed inside the circulating cold water tank 1, thereby realizing active cooling of the cooling water circulating inside the circulating cold water tank 1, meeting its actual needs for circulation, and reducing operating costs. The top and bottom of the rear end of the circulating cold water tank 1 are respectively provided with a first composite pipe fitting 21 and a second composite pipe fitting 22. The first composite pipe fitting 21 and the second composite pipe fitting 22 are structurally connected and are composed of an externally threaded pipe body and a sealing cap connected to one end of the externally threaded pipe body. The other end of the externally threaded pipe body is fixedly sleeved in the corresponding position at the rear end of the circulating cold water tank 1 and communicates with the internal space of the circulating cold water tank 1. This facilitates the replenishment or waterproofing of the internal space of the circulating cold water tank 1 and maintains the continuous operation effect of the circulating cold water tank 1. The top of the circulating cold water tank 1 is equipped with a first cooling water tank 5 and a second cooling water tank 6. Support plates are installed between the first cooling water tank 5 and the second cooling water tank 6, and between the first cooling water tank 5 and the circulating cold water tank 1, forming a superimposed dual cooling space between the internal spaces of the first cooling water tank 5 and the second cooling water tank 6. Belt conveyor devices are installed inside the tops of both the first and second cooling water tanks. Each belt conveyor includes a conveyor belt 24, with drive rollers 25 fitted into friction sleeves at both ends of the conveyor belt 24. The end of the 25 is fitted with the corresponding side wall of the first cooling water tank 5 or the corresponding side wall of the second cooling water tank 6. The rear surface of the first cooling water tank 5 and the rear surface of the second cooling water tank 6 are both equipped with a second servo motor 26. The output end of the second servo motor 26 is connected to one end of the corresponding transmission roller 25. The surface of the conveyor belt 24 is provided with several through-holes for water inlet. The belt conveyor device is used as the automatic moving power of the rubber belt 19 during the cooling process. The belt conveyor device can make the rubber belt 19 completely submerged in water during the conveying process. The front end of the circulating cold water tank 1 is equipped with a water pump 8 capable of pumping cooling water into its own space, a first solenoid valve pipe 9, and a second solenoid valve pipe 10. The first solenoid valve pipe 9 and the second solenoid valve pipe 10 are respectively installed between the output end of the first cooling water tank 5 and the water pump 8, and between the output end of the second cooling water tank 6 and the water pump 8. Furthermore, the bottom of the first cooling water tank 5 and the bottom of the second cooling water tank 6 are both equipped with return solenoid valve pipes 11 that communicate with the circulating cold water tank 1.

[0028] In use, the water circulating inside the circulating cold water tank 1 is actively cooled by the compressor refrigeration system. The working principle is that the heat in the water inside the circulating cold water tank 1 is transferred to the interior of the submerged coil evaporator 4, and then the heat is conducted to the refrigerant inside the submerged coil evaporator 4, where the temperature is even lower. After the refrigerant absorbs heat and evaporates in the submerged coil evaporator 4, it is conducted to the compressor 2 through the existing conduit, where it is drawn in and compressed. Then, the high-temperature and high-pressure refrigerant gas enters the condenser 3, where it releases heat to the ambient air and condenses into a liquid. The liquid refrigerant is throttled and depressurized by the expansion valve and then re-enters the submerged coil evaporator 4 to absorb heat. This process is repeated to achieve the circulation and cooling of the cooling water inside the circulating cold water tank 1. Meanwhile, for the cooling treatment of the rubber belt 19 conveyed by the belt conveyor inside the first cooling water tank 5 and the belt conveyor inside the second cooling water tank 6, the water pump 8 is started. The water pump 8 pumps the cold water inside the circulating cold water tank 1 through the first solenoid valve pipe 9 and the second solenoid valve pipe 10 to the inside of the first cooling water tank 5 and the second cooling water tank 6 respectively. Then, the rubber belt 19 structure inside the first cooling water tank 5 and the rubber belt 19 structure inside the second cooling water tank 6 are subjected to submerged water cooling. The cold water supply is fast and the temperature is low. Compared with the existing long-distance submerged water cooling technology, the length of the first cooling water tank 5 and the second cooling water tank 6 can be shortened, reducing the footprint. The cooling water used in the first cooling water tank 5 and the cooling water used in the second cooling water tank 6 can be returned to the circulating cold water tank 1 through their respective return solenoid valve pipes 11.

[0029] like Figures 1-2 Electronic level gauges 23 are installed inside the top of one side of the first cooling water tank 5 and the top of one side of the second cooling water tank 6. The two electronic level gauges 23 are used to detect the liquid level inside the first cooling water tank 5 and the second cooling water tank 6 in real time, thereby providing electronic conditions for the intelligent manufacturing optimization of the overall device. The detection end of the electronic level gauge 23 extends to the bottom of the first cooling water tank 5 or the bottom of the second cooling water tank 6. Temperature sensors 20 are installed inside the rear end of the first cooling water tank 5 and the rear end of the second cooling water tank 6. Similarly, the two temperature sensors 20 monitor the temperature of the cooling water inside the first cooling water tank 5 and the second cooling water tank 6 in real time.

[0030] During use, considering that rapid cooling can easily cause cracks in the rubber strip 19, the temperature of the cooling water inside the first cooling water tank 5 and the cooling water inside the second cooling water tank 6 can be monitored in real time and controlled accordingly. The specific operation is as follows: As the first cooling channel, the cooling water temperature inside the second cooling water tank 6 should be higher than that inside the first cooling water tank 5. Therefore, by adjusting the opening and closing angles of the solenoid valve inside the second solenoid valve pipe 10 and the solenoid valve inside the corresponding return solenoid valve pipe 11 of the second cooling water tank 6, the cold water inside the circulating cold water tank 1 circulates to the second cooling water tank 6 in a relatively slow manner, maintaining a higher temperature of the cooling water inside the second cooling water tank 6 and avoiding rapid cooling of the rubber belt 19. As the second cooling channel, the cooling water temperature inside the first cooling water tank 5 should be lower than that inside the second cooling water tank 6. Therefore, by adjusting the opening and closing angles of the solenoid valve inside the first solenoid valve pipe 9 and the solenoid valve inside the corresponding return solenoid valve pipe 11 of the first cooling water tank 5, the cold water inside the circulating cold water tank 1 can circulate to the first cooling water tank 5 in a faster manner, maintaining the lower temperature of the cooling water inside the first cooling water tank 5, and then rapidly cooling down the rubber strip 19 whose temperature has initially decreased.

[0031] like Figures 1-2 , Figure 4 On the other side of the first cooling water tank 5 and the other side of the second cooling water tank 6, a first guiding assembly 17 and a second guiding assembly 18 are respectively provided. The first guiding assembly 17 consists of a first arc-shaped frame and a number of first guide rollers that are equidistantly mounted from top to bottom along the arc-shaped circumference of their own structure. One side of the first arc-shaped frame is fixed to the surface of the other side of the second cooling water tank 6. The second guiding assembly 18 consists of a second arc-shaped frame and a number of second guide rollers that are equidistantly mounted from top to bottom along the arc-shaped circumference of their own structure. One side of the second arc-shaped frame is fixed to the surface of the other side of the first cooling water tank 5. Auxiliary return water tanks 27 are installed on both sides of the second cooling water tank 6, and the opening of the top structure of the auxiliary return water tank 27 can cover the positions of the first guiding assembly 17 and the second guiding assembly 18.

[0032] During use, considering the stability of the subsequent movement of the rubber strip 19 between the first cooling water tank 5 and the second cooling water tank 6, the first guide component 17 and the second guide component 18 are used for switching support, and the auxiliary return water tank 27 can help collect the cooling water dripping from the surface of the rubber strip 19 to avoid contaminating the processing environment.

[0033] like Figures 4-5A composite flow guide pipe 7 is installed in the bottom of both the first cooling water tank 5 and the bottom of the second cooling water tank 6. The composite flow guide pipe 7 includes a first horizontal pipe 71 and a second horizontal pipe 72. The first horizontal pipe 71 is fixedly installed in the bottom of the first cooling water tank 5 or the bottom of the second cooling water tank 6. Several horizontal branch pipes 73 are installed between the second horizontal pipe 72 and the first horizontal pipe 71. Several flow guide pipes 74 are installed along the structure of the branch pipes 73 from front to back. One end of the second horizontal pipe 72 is connected to the end of the second solenoid valve pipe 10 away from the circulating cold water tank 1 or the end of the first solenoid valve pipe 9 away from the circulating cold water tank 1. In this way, the composite flow guide pipe 7 can improve the uniformity of cooling water circulation by synchronously guiding the cooling water over a large area, thereby avoiding the formation of temperature difference areas in the first cooling water tank 5 or the second cooling water tank 6 and improving the cooling effect on the rubber belt 19.

[0034] During use, during the flow guidance process of the second solenoid valve tube 10 or the first solenoid valve tube 9, the cooling water will enter the corresponding second horizontal tube 72, and then be diverted to the interior of multiple branch pipes 73. Then, it will be synchronously guided through several guide pipes 74 set on the multiple branch pipes 73, thereby avoiding the local temperature difference problem caused by water changing at a single location. In addition, the overall structure of the composite guide pipe 7 can also provide structural support for the corresponding belt conveyor.

[0035] like Figures 4-7 The guide pipe 74 is inclined, and the output direction of the open port of the guide pipe 74 faces the bottom inner wall of the first cooling water tank 5 or the bottom inner wall of the second cooling water tank 6. Semi-cylindrical grooves are provided on the bottom of the other side of the first cooling water tank 5 and the bottom of the other side of the second cooling water tank 6. Right-angle pipes 12 are fixed to the front end of the other side of the first cooling water tank 5 and the front end of the other side of the second cooling water tank 6. The right-angle pipes 12 are connected to the front end of the corresponding semi-cylindrical grooves. The end of the right-angle pipe 12 away from the first cooling water tank 5 or the second cooling water tank 6 is a 90-degree vertical structure, and the outer end of the right-angle pipe 12 away from the first cooling water tank 5 or the second cooling water tank 6 is fitted with a device for collecting plastic particles in the cooling water. The composite collection component 13 includes a transparent sleeve 131. The surface of the end port of the right-angle tube 12 away from the first cooling water tank 5 or the second cooling water tank 6 is provided with an external thread. The bottom inner wall of the transparent sleeve 131 is provided with an internal thread that can be helically engaged with the external thread, so that its bottom structure can be threadedly connected to the surface of the end port of the right-angle tube 12 away from the first cooling water tank 5 or the second cooling water tank 6. An inverted cone 132 is fixedly sleeved in the middle of the transparent sleeve 131. A filter screen 133 is fixedly nested in the side wall of the inverted cone 132. A sealing cover plate is connected to the top of the transparent sleeve 131 with an internal thread. A handle is fixedly fixed on the top of the sealing cover plate to facilitate subsequent screwing and force application. Both semi-cylindrical slots are fitted with helical rods 14, and one end of each helical rod 14 is set as a smooth rod structure and passes through the rear end sidewall of the first cooling water tank 5 and the rear end sidewall of the second cooling water tank 6 respectively. A synchronous belt 15 is fitted between the ends of the two helical rods 14, and one end of one helical rod 14 is connected to a first servo motor 16 mounted on the surface of the first cooling water tank 5. A sealing ring is nested at the fitting point between the helical rod 14 and the second cooling water tank 6 or the fitting point between the helical rod 14 and the first cooling water tank 5 to ensure the sealing effect of the connection.

[0036] During use, considering the issue of plastic particles being generated in the first cooling water tank 5 and the second cooling water tank 6 due to the reciprocating friction between the rubber belt 19 and the belt conveyor, plastic recycling will be carried out through the composite collection component 13, right-angle tube 12, spiral rod 14, and related structures. The specific operation is as follows: During the cooling water replacement process of the two composite guide pipes 7, several inclined guide pipes 74 ensure their own output while using the inclined water flow they generate to push the plastic particles deposited on the bottom inner wall of the first cooling water tank 5 or the bottom inner wall of the second cooling water tank 6 to the corresponding semi-cylindrical groove, thereby realizing the automated cleaning and collection of plastic particles. Next, without stopping the machine, the first servo motor 16 can be periodically started and stopped. When the first servo motor 16 is started, its output drives the corresponding screw rod 14 to rotate synchronously. Under the linkage of the synchronous belt 15, the other screw rod 14 will also rotate synchronously. Then, the two screw rods 14 will force the plastic particles in the two semi-cylindrical grooves and part of the cooling water through the two right-angle tubes 12 into the annular space formed by the transparent sleeve 131 and the inverted cone 132 in the two composite collection components 13. When the first servo motor 16 is stopped, the screw rods 14 stop screw conveying, and the cooling water is... The plastic particles flow back due to gravity, while the plastic particles remain in the annular space due to the filtration of the filter screen 133. This process repeats, enabling automatic recycling of plastic particles inside the first cooling water tank 5 and the second cooling water tank 6 without shutting down the entire equipment. After a certain amount of plastic particles are collected in the annular space, the handle is turned to remove the sealing cover from the top of the transparent sleeve 131, allowing for centralized collection of the plastic particles in the annular space. Alternatively, the composite collection assembly 13 can be turned to detach it from the corresponding right-angle tube 12, and then a new composite collection assembly 13 can be installed.
