Description

Technical Field

[0001] This utility model relates to the field of rubber production technology, specifically a cooling device for the production of recycled rubber. Background Technology

[0002] In the production of reclaimed rubber, rubber powder is desulfurized and then mechanically refined and shaped to produce reclaimed rubber. Because the rubber compound retains a certain amount of heat during refining, directly shearing and rolling the reclaimed rubber into sheets or rolls after refining significantly impacts its properties, resulting in less than ideal performance. The most common problem is Mooney rebound, which also affects the elongation and strength of the finished rubber product. Therefore, it is necessary to cool the reclaimed rubber after refining.

[0003] Existing recycled rubber cooling equipment requires manual guidance of the refined rubber strips before operation. The strips are immersed in coolant, and the initial end of the freshly refined rubber strip passes through the cooling device before being fed onto the conveyor belt for the next processing step. This manual guidance is inefficient and, given the weight of the rubber products, places a significant burden on the workers.

[0004] In existing recycled rubber cooling devices, the rubber strips are usually in direct contact with the coolant inside the device during operation. The overall temperature of the coolant inside the device rises rapidly, making it difficult to cool the coolant in time. This gradually affects the cooling effect of the device on the rubber, resulting in poor rubber setting effect. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for the production of recycled rubber, in order to solve the problems of low efficiency of manually guiding rubber strips and rapid temperature rise of the internal coolant when the cooling device is working, as mentioned in the prior art.

[0023] Example: Figure 1 - Figure 5 As shown, this utility model provides a technical solution for a cooling device for the production of recycled rubber, including a box body 1. Two second isolation plates 5 are fixedly connected to the rear side of the inside of the box body 1. A first isolation plate 3 adapted to the two second isolation plates 5 is provided on the front side of the two second isolation plates 5. Threaded rods 7 are rotatably installed on both sides of the top of the box body 1. Transmission rods 8 are threadedly connected to the outer sides of the two threaded rods 7. A fixing plate 10 is provided between the two transmission rods 8. A clamping plate 11 is provided on the top of the fixing plate 10. A clamping opening adapted to the clamping plate 11 is opened on the top of the fixing plate 10.

[0024] A rotating shaft 2 is fixedly connected to one side of the top of the first isolation plate 3. The rotating shaft 2 is rotatably connected to the inside of the box 1. A first motor is fixedly connected to one side of the box 1. The output end of the first motor is fixedly connected to the rotating shaft 2. A first guide roller 4 is rotatably installed at both the front and rear ends of the first isolation plate 3.

[0025] A second motor is fixedly connected to both sides of the top of the housing 1. The output end of the second motor is fixedly connected to two threaded rods 7 respectively. A pull rod 9 is hinged to one bottom end of each of the two transmission rods 8. The end of each pull rod 9 away from the two transmission rods 8 is hinged to a fixed plate 10. A second sliding groove 20 is opened on both sides of the inner side wall of the housing 1. A pair of pulleys 21 are fixedly connected to both ends of the fixed plate 10. The two ends of the fixed plate 10 are slidably connected to the two second sliding grooves 20 through the pulleys 21 respectively. The threaded rods 7 drive the fixed plate 10 to move forward along the second sliding grooves 20, bringing the rubber strip to the front of the device.

[0026] Two first limiting blocks 13 are fixedly connected to the top of the fixed plate 10. The bottom ends of the two first limiting blocks 13 pass through both ends of the clamping plate 11 and are slidably connected to the clamping plate 11. Two first sliding grooves 12 are opened inside the fixed plate 10. An inclined block 14 is slidably connected inside the first sliding groove 12. Both ends of the clamping plate 11 are provided with limiting grooves 15 that are adapted to the inclined block 14. Springs 19 are fixedly connected to the bottom of both ends of the clamping plate 11. The other ends of the two springs 19 are fixedly connected to the fixed plate 10. Before operation, the rubber strip is clamped by the fixed plate 10 and the clamping plate 11. Then, one end of the rubber strip is moved to the front of the device, so that the rubber strip does not need to be manually pulled and guided.

[0027] Two inclined blocks 14 are fixedly connected to a connecting plate 16 at their bottom. A slider 17 is fixedly connected to one end of the connecting plate 16. One end of the fixing plate 10 passes through the slider 17 and is slidably connected to the slider 17. A limit hook 18 is hinged to the top of the slider 17. A limit tooth groove adapted to the limit hook 18 is opened at the bottom of one end of the fixing plate 10.

[0028] A water outlet 6 is provided on the rear side of the housing 1. A baffle mesh adapted to the water outlet 6 is fixedly connected to the rear side of the interior of the housing 1. A heat exchanger 22 is fixedly connected to the bottom of the housing 1. A water pump 23 is fixedly connected to the front side of the housing 1. The water outlet 6, the heat exchanger 22 and the water pump 23 are interconnected through water pipes. The output end of the water pump 23 is connected to the front side of the interior of the housing 1. When working, the water pump 23 draws the coolant near the water outlet 6 into the heat exchanger 22. The hot coolant is cooled by the heat exchanger 22 and then flows to the front side of the interior of the housing 1 through the water pump 23.

[0029] Electric push rods 24 are fixedly connected to both sides of the housing 1. The output ends of the two electric push rods 24 are fixedly connected to brackets 25. Slide rods 26 are fixedly connected to the four corners of the bottom of the brackets 25. Second guide rollers 27 are rotatably installed between each pair of slide rods 26. Four second limit blocks 28 are fixedly connected to the inner wall of the housing 1. The four second guide rollers 27 are slidably connected to the inside of the four second limit blocks 28. Two third guide rollers 29 are rotatably connected inside the housing 1. The second guide rollers 27 and the third guide rollers 29 ensure that the rubber strip is located in the middle of the inside of the housing 1 during operation, thereby facilitating the cooling of the rubber strip by the coolant inside the housing 1.

[0030] In use, the present invention is as follows: conveying devices are provided on both the front and rear sides of the box 1. The newly processed rubber strip is guided into the box 1 through the conveying devices and then sent to the next processing step. At the start of each work, the conveying device transports the newly processed rubber strip into the box 1. At this time, the worker can insert the front end of the rubber strip between the fixing plate 10 and the clamping plate 11, and then pull the slider 17. The slider 17 moves and drives the inclined block 14 to move towards the inclined surface of the limiting groove 15 through the connecting plate 16. When the inclined block 14 contacts the limiting groove 15, the clamping plate 11 moves downward under the action of the inclined surface of the inclined block 14 and compresses the spring 19, thereby clamping the rubber strip. After clamping, the worker can rotate the limiting hook 18 so that the barb at the front end of the limiting hook 18 is engaged in the limiting tooth groove, preventing the clamping plate 11 from moving upward under the action of the spring force of the spring 19, thereby releasing the fixation of the rubber strip.

[0031] After the rubber strip is fixed, the second motor drives the threaded rod 7 to rotate, causing the transmission rod 8 to move towards the front of the box 1. At this time, the transmission rod 8 pulls the fixing plate 10 forward inside the second slide groove 20 through the pull rod 9. The water level inside the box 1 is higher than the middle section of the second slide groove 20. At this time, the fixing plate 10 pulls the rubber strip forward under the water surface, cooling the rubber strip while guiding it to the conveying device at the front of the box 1. After the fixing plate 10 enters the front end of the second slide groove 20, it leaves the water surface, making it convenient for the worker to release the clamping plate 11 from the rubber strip. Then, the worker puts the rubber strip into the conveying device at the front of the box 1, thus completing the guidance of the rubber strip. The transmission rod 8 guides the rubber strip clamped by the clamping plate 11 to the front of the box 1, improving the guiding efficiency of the rubber strip. It eliminates the need for manual guidance of the rubber strip every time the work is done or the rubber strip width is changed, reducing the burden on the workers.

[0032] After the guidance is completed, the electric push rod 24 and the first motor work simultaneously. The electric push rod 24 drives the second guide roller 27 to move downward through the bracket 25, pressing the rubber strip between the third guide roller 29 and the second guide roller 27 for transport. At this time, the rubber strip is located in the middle of the water level inside the tank 1, thereby improving the cooling efficiency of the rubber strip. The first motor drives the first isolation plate 3 to rotate around the shaft 2. When the first isolation plate 3 and the second isolation plate 5 are in close contact, the first motor stops working. At this time, the first isolation plate 3 and the two second isolation plates 5 form a separate cooling channel, thereby isolating the coolant in the cooling channel from the coolant inside the tank 1. During operation, the rubber strip... The rubber strip first enters the cooling channel for cooling. After the liquid inside the cooling channel comes into contact with the rubber strip, the temperature rises rapidly. At this time, the water pump 23 starts to work, and the high-temperature coolant is drawn from the outlet 6 into the heat exchanger 22 for cooling. The working method of the heat exchanger 22 is a mature existing technology, so it will not be described in detail here. The cooled liquid in the heat exchanger 22 is transported back to the inside of the box 1 by the water pump 23. The water pump 23 directly draws away the high-temperature liquid in the cooling channel for cooling, so that the temperature of the coolant inside the box 1 can always be kept at a low level, preventing the overall temperature of the coolant inside the box 1 from rising and affecting the cooling and shaping effect of the device on the rubber strip.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
