Description

Technical Field

[0001] This invention relates to the field of cooling device technology, and in particular to a cooling device for the production of rubber products. Background Technology

[0002] In the process of rubber product manufacturing, small or micro rubber products are obtained after hot melting, and then they usually need to be cooled to solidify and harden the rubber products so that they have the required physical properties and chemical stability.

[0003] For example, a cooling device for rubber product manufacturing, patent number CN224089450U, uses a rack and pinion mechanism. When the electro-hydraulic actuator moves the cooling frame up and down in the water tank, the rack drives the gear to rotate, which in turn drives the cam and paddle to rotate via the drive rod. During the rotation of the cam, the rubber products on the surface of the perforated mesh plate vibrate. When the cooling frame is placed underwater, the cooling effect of the rubber products is improved. At the same time, the drive rod drives the paddle to agitate the water in the water tank, further improving the cooling efficiency of the rubber products. When the cooling frame is placed on the water, the water droplets on the surface of the rubber products can be quickly drained, and the water can be easily collected by the workers.

[0004] However, in actual operation, simply shaking the rubber product above the perforated mesh plate is not enough to effectively allow the liquid to fully contact the product for cooling, or to quickly drain the liquid on its surface when the cooling frame is on the water. At the same time, the water flow stirred by the agitator cannot fully contact the rubber product for cooling due to the direction of the flow. Summary of the Invention

[0005] The purpose of this invention is to provide a cooling device for the production of rubber products.

[0006] The technical problem of this invention is mainly solved by the following technical solution: A cooling device for rubber product manufacturing includes a cooling box. The cooling box contains a grid that divides it into a cooling chamber and an air storage chamber. A stud, driven by a motor, passes through the air storage chamber and extends into the cooling chamber from the bottom of the cooling box. An air inlet channel is axially arranged in the stud. One-way air inlet pipes I, communicating with the air inlet channel, are provided at both the upper and lower ends of the stud within the air storage chamber. Pressure plates are screwed onto the studs between multiple sets of one-way air inlet pipes I. One-way air inlet pipes II are provided on the side walls of the air storage chamber on both the upper and lower sides of the pressure plates. The stud within the cooling chamber… Both sides of the column are provided with strip-shaped openings communicating with the air intake channel. The cooling chamber is provided with a stirring paddle passing through the two sets of strip-shaped openings. The stirring paddle is provided with an air outlet channel. The top of the stirring paddle is provided with a one-way air outlet pipe communicating with the air outlet channel. The bottom of the stirring paddle is also provided with a vertical pipe communicating with the air outlet channel. The bottom end of the vertical pipe extends into the air intake channel below the strip-shaped opening. The stirring paddle is also provided with a round tube sleeved on a stud. A threaded tube is screwed onto the stud above the round tube. The round tube and the threaded tube are rotatably connected. A cleaning basket is also provided on the threaded tube.

[0007] Preferably, a roller assembly is radially arranged at the bottom of the cleaning basket, and a limiting groove for accommodating the rollers on the roller assembly is axially arranged on the inner wall of the cooling box.

[0008] Preferably, the bottom of the side wall of the cleaning basket is provided with a discharge port evenly distributed, and the top of the side wall of the cooling box is provided with a discharge pipe corresponding to the discharge port. One end of the discharge pipe is attached to the corresponding outer wall of the cleaning basket. An annular plate is provided on the inner wall of the cooling box above the discharge pipe. A counterweight block is provided below the annular plate, which is offset from the discharge pipe. A pulley group corresponding to the counterweight block is provided on the top of the side wall of the cleaning basket. A connecting rope is provided on the pulley group, one end of which is connected to the corresponding counterweight block. The other end of the connecting rope is connected to a sealing cylinder inside the cleaning basket that seals the discharge port.

[0009] Preferably, a cylinder fitted over a spiral tube is provided in the middle of the cleaning basket, a slider is provided at the bottom of the inner wall of the cylinder, a groove for accommodating the slider is provided axially on the outer wall of the spiral tube, a base is provided on both sides of the bottom of the cleaning basket, an inclined surface is provided on both sides of the bottom of the base, and a top seat corresponding to the base is provided at the top of both ends of the stirring paddle, the top of the top seat abutting against the top of the inclined surface corresponding to the base, wherein the two sets of bases are located between the two sets of top seats.

[0010] Preferably, the diameter of the air intake channel in the cooling chamber is smaller than the diameter of the air intake channel in the air storage chamber, and the diameter of the vertical pipe is adapted to the inner diameter of the air intake channel in the cooling chamber.

[0011] Preferably, a limiting rod is vertically arranged inside the gas storage cavity, passing through a through hole in the pressure plate, and the size of the pressure plate is adapted to the size of the gas storage cavity.

[0012] Preferably, the bottom of the spiral tube is provided with an expansion section to accommodate the bearing. The expansion section is located below the cleaning basket. The bearing is fixed on the top of the circular tube. The stirring paddle is located below the expansion section. The circular tube is fixedly connected to the stirring paddle. The inner diameter of the circular tube is larger than the diameter of the stud.

[0013] The beneficial effects of this invention are as follows: In this invention, the motor rotates in both directions to drive the cleaning basket and pressure plate to move up and down via the stud, thereby moving the cleaning basket and its internal products up and down in the liquid. At this time, the rotating stud drives the stirring paddle to rotate as well, so as to make the liquid surge up and fully contact the products in the cleaning basket by mechanically agitating the liquid. At the same time, the pressure plate squeezes the gas in the gas storage chamber and sprays it out through the vertical pipe, the gas outlet channel and several one-way gas outlet pipes. The constantly rotating stirring paddle drives the one-way gas outlet pipes to rotate, so that the gas sprayed out can cover the entire bottom of the cleaning basket. This achieves the goal of improving the contact between the liquid and the product by mechanically agitating and pneumatically agitating the liquid, thereby enhancing the cooling effect and efficiency. At the same time, when the product is cooling or draining, the rotating stirring paddle, top seat and base shake the product in the cleaning basket to improve the product cooling effect. The combination of shaking the product in the cleaning basket and spraying gas from the one-way gas outlet pipes further improves the drainage effect and efficiency of the product in the cleaning basket.

[0016] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0017] A cooling device for rubber product manufacturing includes a cooling box 1. The cooling box 1 is provided with a grid plate 103 that divides it into a cooling chamber 101 and an air storage chamber 102. A stud 2 is provided at the bottom of the cooling box 1, passing through the air storage chamber 102 and extending into the cooling chamber 101. The stud 2 is driven by a motor 3. An air inlet channel 4 is provided axially in the stud 2. Both the upper and lower ends of the stud 2 in the air storage chamber 102 are provided with one-way air inlet pipes I5 communicating with the air inlet channel 4. A pressure plate 6 is screwed onto the stud 2 between the multiple sets of one-way air inlet pipes I5. One-way air inlet pipes II7 are provided on the side walls of the air storage chamber 102 on both the upper and lower sides of the pressure plate 6.

[0018] Both sides of the stud 2 in the cooling chamber 101 are provided with strip-shaped openings 8 that communicate with the air intake channel 4. The cooling chamber 101 is provided with a stirring paddle 9 that passes through the two sets of strip-shaped openings 8. The stirring paddle 9 is provided with an air outlet channel 10. The top of the stirring paddle 9 is provided with a one-way air outlet pipe 11 that communicates with the air outlet channel 10. The bottom of the stirring paddle 9 is also provided with a vertical pipe 12 that communicates with the air outlet channel 4. The bottom end of the vertical pipe 12 extends into the air intake channel 4 below the strip-shaped openings 8.

[0019] The stirring paddle 9 is also provided with a circular tube 13 sleeved on the stud 2. A screw tube 14 is screwed onto the stud 2 above the circular tube 13. The circular tube 13 and the screw tube 14 are rotatably connected. A cleaning basket 15 is also provided on the screw tube 14. An expansion portion 32 for accommodating a bearing 33 is provided at the bottom of the screw tube 14. The expansion portion 32 is located below the cleaning basket 15. The bearing 33 is fixed on the top of the circular tube 13. The stirring paddle 9 is located below the expansion portion 32. The circular tube 13 is fixedly connected to the stirring paddle 9. The inner diameter of the circular tube 13 is larger than the diameter of the stud 2.

[0020] The bottom of the cleaning basket 15 is radially provided with a roller assembly 16, and the inner wall of the cooling box 1 is axially provided with a limiting groove 17 to accommodate the rollers on the roller assembly 16. When the stud 2 rotates in the screw tube 14 and drives the cleaning basket 15 to move up and down, it also drives the rollers in the roller assembly 16 to move up and down in the limiting groove 17. By locking the roller assembly 16 in the limiting groove 17, the cleaning basket 15 and the screw tube 14 are prevented from rotating together with the stud 2, so that the screw tube 14 and the cleaning basket 15 can move up and down on the rotating stud 2.

[0021] The bottom of the side wall of the cleaning basket 15 is evenly provided with discharge ports 18, and the top of the side wall of the cooling box 1 is provided with a discharge pipe 19 corresponding to the discharge port 18. One end of the discharge pipe 19 is attached to the corresponding outer wall of the cleaning basket 15. An annular plate 20 is provided on the inner wall of the cooling box 1 above the discharge pipe 19. A counterweight 21 is provided below the annular plate 20 and is offset from the discharge pipe 19. A pulley group 22 corresponding to the counterweight 21 is provided on the top of the side wall of the cleaning basket 15. A connecting rope 23 is provided on the pulley group 22, one end of which is connected to the corresponding counterweight 21. The other end of the connecting rope 23 is connected to the sealing cylinder 24 inside the cleaning basket 15 that seals the discharge port 18.

[0022] A cylindrical tube 25, which is sleeved on a spiral tube 14, is provided in the middle of the cleaning basket 15. A slider 26 is provided at the bottom of the inner wall of the cylindrical tube 25. A groove 27 for accommodating the slider 26 is provided axially on the outer wall of the spiral tube 14. A base 28 is provided on both sides of the bottom of the cleaning basket 15. An inclined surface 29 is provided on both sides of the bottom of the base 28. A top seat 30 corresponding to the base 28 is provided at the top of both ends of the stirring paddle 9. The top of the top seat 30 abuts against the top of the inclined surface 29 of the base 28. The two sets of bases 28 are located between the two sets of top seats 30.

[0023] The diameter of the air intake channel 4 in the cooling chamber 101 is smaller than the diameter of the air intake channel 4 in the air storage chamber 102, and the diameter of the vertical pipe 12 is adapted to the inner diameter of the air intake channel 4 in the cooling chamber 101.

[0024] A limiting rod 31 is vertically installed inside the gas storage chamber 102, passing through a through hole in the pressure plate 6. The size of the pressure plate 6 is adapted to the size of the gas storage chamber 102. When the stud 2 rotates in the screw hole in the pressure plate 6, the limiting rod 31 can limit the vertical movement of the pressure plate 6, preventing it from rotating together with the stud 2 and affecting the vertical movement of the pressure plate 6.

[0025] like Figure 2 As shown, the weight of the sealing cylinder 24 is greater than that of the counterweight 21, so that it is located at the bottom of the cleaning basket 15 to seal the discharge port 18. At the same time, the counterweight 21 is pulled by the connecting rope 23 on the pulley group 22. When the product is placed in the cleaning basket 15, the motor 3 rotates forward to drive the stud 2 to rotate in the screw hole in the pressure plate 6 and in the screw tube 14, thereby driving the pressure plate 6 and the cleaning basket 15 to move down.

[0026] During the above process, when the cleaning basket 15 moves downward, it will drive the roller assembly 16 to slide downward in the positioning groove 17. When the screw tube 14 and the cleaning basket 15 move up and down on the rotating stud 2, since the counterweight 21 and the discharge pipe 19 are misaligned, when the cleaning basket 15 drives the counterweight 21 and other components to move downward, the discharge pipe 19 will not block the counterweight 21 and affect its downward movement. During the downward movement of the screw tube 14 and the cleaning basket 15, the screw tube 14 will pass through the expansion section 32, the bearing 33 and the circular... The tube 13 drives the agitator 9 to move downward within the strip-shaped opening 8. The downward-moving agitator 9, in turn, drives the vertical tube 12 to move downward within the air intake channel 4. This causes the rotating stud 2 to abut against the agitator 9 through the side wall of the strip-shaped opening 8, causing it to rotate together. During this process, the agitator 9 drives the circular tube 13 to rotate within the bearing 33. Both the agitator 9 and the vertical tube 12 are indirectly affected by the downward-moving screw tube 14, ensuring that neither affects the downward movement of the screw tube 14 or the cleaning basket 15. When the cleaning basket 15 moves its internal products downward and immerses them in the liquid, the stirring paddle 9, which is rotated by the screw 2, agitates the liquid in the cooling chamber 101, causing it to surge upward and come into contact with the products in the cleaning basket 15 to cool them down. During this process, the stirring paddle 9 is always located at a fixed position below the cleaning basket 15, so that the liquid it agitates can fully contact the products in the cleaning basket 15. During this process, the rotating stirring paddle 9 will cause the top seat 30 to contact and squeeze the corresponding inclined surface 29 at the bottom of the base 28, thereby lifting the base 28 and moving the cleaning basket 15 upward. At this time, the upward-moving cleaning basket 15 drives the slider 26 to move upward in the slide groove 27 through the cylinder 25. When the top seat 30 separates from the base 28, under the influence of the weight of the cleaning basket 15 and its internal products, the slider 26 moves downward in the slide groove 27 through the cylinder 25, thereby shaking the products in the cleaning basket 15 to ensure full contact with the liquid and improve the cooling efficiency and effect.

[0027] When the stud 2 rotates and drives the pressure plate 6 to move downward in the air storage chamber 102, the pressure plate 6 will compress the air in the air storage chamber 102 below it, so that the gas enters the air intake channel 4 through the lower one-way air intake pipe I5, and then is sprayed out through the vertical pipe 12, the air outlet channel 10 and several one-way air outlet pipes 11. At this time, the rotating agitator 9 drives several one-way air outlet pipes 11 to rotate to cover the entire bottom surface of the cleaning basket 15, so that the sprayed gas can agitate the liquid in the cooling chamber 101, so that the liquid can fully contact the product in the cleaning basket 15 to cool it. During the above process, when the pressure plate 6 moves downward in the air storage chamber 102, it acts as a piston, so that the moving pressure plate 6 will force the external gas into the air storage chamber 102 above the pressure plate 6 through the upper one-way air intake pipe II7 to complete the gas injection work.

[0028] When the stud 2 reverses, it drives the pressure plate 6 to move upward, causing the pressure plate 6 to compress the gas in the upper air storage chamber 102 and enter the air intake channel 4 through the upper one-way air intake pipe I5. Then, it is ejected through the vertical pipe 12, the air outlet channel 10 and several one-way air outlet pipes 11. At the same time, the external gas is forced into the air storage chamber 102 below the pressure plate 6 through the lower one-way air intake pipe II7 to complete the gas injection work.

[0029] When the motor 3 reverses and forces the cleaning basket 15 to slide out of the liquid through the solenoid 14, the gas in the air storage chamber 102 above the pressure plate 6 is ejected through the one-way air inlet pipe 15, the air inlet channel 4, the vertical pipe 12, the air outlet channel 10, and the one-way air outlet pipe 11. This allows the gas ejected from the one-way air outlet pipe 11 to dry the product in the cleaning basket 15, accelerating the draining of liquid from its surface. At the same time, the rotating agitator 9 drives the top seat 30 to press against the inclined surface 29, thereby driving the base 28 and causing the cleaning basket 15 to shake up and down. This shaking of the cleaning basket 15 also accelerates the draining of liquid from the surface of the product inside.

[0030] When it is necessary to drain the products from the cleaning basket 15, such as Figure 3 As shown, the motor 3 reverses to drive the stud 2, which in turn drives the screw tube 14 and the cleaning basket 15 to move upward. When the upward-moving cleaning basket 15 causes the counterweight 21 to contact the bottom of the annular plate 20, the stud 2 rotates to drive the cleaning basket 15 to continue moving upward. The annular plate 20 abuts against the counterweight 21, and the counterweight 21 pulls the sealing cylinder 24 through the connecting rope 23, causing it to move upward inside the cleaning basket 15 during the upward movement. This causes the sealing cylinder 24 to open the discharge port 18. Finally, the upward-moving cleaning basket 15 drives the discharge port 18 to align with the discharge pipe 19. Then, by opening the discharge pipe 19, people can sweep the product to the discharge port 18 and discharge it through the corresponding discharge pipe 19, thus facilitating the discharge of the product from the cleaning basket 15. Of course, the product can also be manually removed from the cleaning basket 15.

[0031] This invention repeats the above steps, causing the motor 3 to rotate in both directions to drive the cleaning basket 15 and the pressure plate 6 to move up and down via the stud 2. This causes the cleaning basket 15 and its contents to move up and down in the liquid. During this process, the rotating stud 2 drives the stirring paddle 9 to rotate as well, mechanically agitating the liquid to make it surge upwards and fully contact the contents of the cleaning basket 15. Simultaneously, the pressure plate 6 compresses the gas in the gas storage chamber 102 and ejects it through the vertical pipe 12, the gas outlet channel 10, and several one-way gas outlet pipes 11. The constantly rotating stirring paddle 9 drives the one-way gas outlet... The air pipe 11 rotates, allowing the gas it sprays to cover the entire bottom of the cleaning basket 15. This enhances the contact between the liquid and the product through mechanical and pneumatic agitation, thereby improving the cooling effect and efficiency. Simultaneously, when the product is cooling or draining, the rotating agitator 9, top seat 30, and base 28 shake the product inside the cleaning basket 15 to improve the cooling effect. Furthermore, the combination of shaking the product inside the cleaning basket 15 and spraying gas from the one-way air pipe 11 further enhances the draining effect and efficiency of the product inside the cleaning basket 15.

[0032] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
