Description

Technical Field

[0001] The utility model relates to the technical field of rubber cooling, in particular to a rubber strip cooling device. Background Art

[0002] Automobile rubber sealing strips are common automobile parts. When using a rubber extruder to produce and extrude rubber strips, since the temperature of the rubber strips is relatively high when they are just extruded, it is necessary to quickly cool and shape them to avoid deformation of the produced rubber strips. Currently, water is mostly poured on the rubber strips or the rubber strips are passed through a coolant for water cooling.

[0003] After the water cooling of the rubber strips, the rubber strips still have residual temperature and residual water. Relying only on natural cooling and evaporation of water is less efficient, which affects subsequent processing and storage operations. Therefore, it is necessary to perform air-cooling and drying treatment on the water-cooled rubber strips. Content of the Utility Model

[0004] To solve the technical problems in the background art, the utility model proposes a rubber strip cooling device.

[0005] A rubber strip cooling device proposed by the utility model is mainly used for cooling the residual temperature after the water cooling of the rubber strips. Specifically, it includes an air-cooling box. Feed traction machines and discharge traction machines are respectively installed at both ends of the air-cooling box. The rubber strips are conveyed from the feed traction machine to the discharge traction machine. A box body is installed on the side of the air-cooling box. A transmission mechanism is installed on the box body. A plurality of cross bars are installed on the transmission mechanism. The transmission mechanism drives the plurality of cross bars to enter the air-cooling box in sequence. The rubber strips are successively placed on the cross bars entering the air-cooling box, and the rubber strips form a V shape between two adjacent cross bars.

[0006] As a further optimized solution of the utility model, the transmission mechanism includes a sprocket, a chain and a driving wheel. The number of sprockets is two, and they are rotatably installed on both sides of the upper end face of the box body. The two sprockets are connected by chain drive. The driving wheel is rotatably installed on the upper end face of the box body and meshed with one of the sprockets. A plurality of cross bars are all installed on the chain and evenly distributed along the circumference of the chain.

[0007] As a further optimized solution of the utility model, the outer circumference of the chain has a U-shaped frame. The upper bottom and the lower bottom of the U-shaped frame are respectively connected to the upper and lower chain plates of adjacent chain links. The side of the U-shaped frame faces outward and is fixedly connected to the end face of the cross bar.

[0008] As a further optimized solution of the utility model, the driving wheel is an incomplete sprocket. The chain teeth on the outer circumference of the driving wheel are continuous and the length is equal to the length of the chain link between two adjacent cross bars.

[0009] As a further optimized solution of the utility model, a through slot arranged along the length direction of the air cooling box is opened on one side close to the box body, and the transmission mechanism drives multiple cross bars to pass through the through slot in sequence and enter the air cooling box.

[0010] As a further optimized solution of the utility model, the distance between the inner walls at both ends of the through groove and the axis of the adjacent sprocket is greater than the length of the cross bar.

[0011] As a further optimized solution of the utility model, a roller is rotatably installed on the end of the cross bar away from the box body, and a stabilizing plate is installed on the inner wall of the air-cooled box away from the box body. When the transmission mechanism drives the cross bar in the air-cooled box to move, the cross bar drives the roller to roll on the upper surface of the stabilizing plate.

[0012] As a further optimized solution of the utility model, the height of the discharge port of the feed tractor and the height of the feed port of the discharge tractor are both greater than the height of the cross bar.

[0013] As a further optimized solution of the utility model, evenly distributed air outlet nozzles are installed on the upper surface of the air outlet plate, and the interior of the air outlet plate has a cavity connected to the air outlet nozzles, and the cavity is connected to the air outlet of an external air blowing device.

[0014] The rubber strip cooling device proposed by the utility model has the following beneficial effects:

[0015] The water-cooled rubber strips are transmitted to the air-cooling box by the feeding tractor and pulled out by the discharging tractor. The rubber strips are set on the cross bars. With the continuous traction of the feeding tractor, the rubber strips gradually sag at the feeding end of the air-cooling box. The transmission mechanism is used to drive multiple cross bars to operate, so that the cross bars located outside the air-cooling box pass through the through slots into the air-cooling box, and push the upper rubber strips toward the discharging tractor. The operation is cyclically operated to realize V-shaped continuous arrangement of the rubber strips in the air-cooling box, increase the residence time and residence area of ​​the rubber strips in the air-cooling box, thereby extending the air cooling area and duration of the air outlet plate for the rubber strips, dissipating the residual temperature and residual water on the rubber strips, which is beneficial to improving the actual cooling effect and facilitating subsequent processing and storage operations.

[0025] See also Figure 1 and Figure 2 A rubber strip cooling device is mainly used for cooling the residual heat of the rubber strip after extrusion and water cooling. It specifically includes an air cooling box 1. A feeding tractor 2 and a discharging tractor 3 are respectively installed at both ends of the air cooling box 1. The rubber strip 7 is transported from the feeding tractor 2 to the discharging tractor 3. A box body 5 is installed on the side of the air cooling box 1. A transmission mechanism is installed on the box body 5. A plurality of cross bars 6 are installed on the transmission mechanism. The plurality of cross bars 6 are driven to enter the air cooling box 1 in sequence through the transmission mechanism. The rubber strips 7 are sequentially laid on the cross bars 6 entering the air cooling box 1, and the rubber strips 7 form a V shape between two adjacent cross bars 6.

[0026] Specifically, the air cooling box 1 includes a bottom plate, and fixed plates are installed on both sides of the bottom plate to form a U-shaped groove, and the feed tractor 2 and the discharge tractor 3 are respectively installed on the top of the openings on both sides of the U-shaped groove, and the air outlet plate 4 is installed on the bottom plate, and air is blown into the U-shaped groove through the air outlet plate 4, so as to air-cool the rubber strip 7 in the U-shaped groove;

[0027] Furthermore, the feed tractor 2 and the discharge tractor 3 are both common rubber strip tractors in the prior art;

[0028] Specifically, the transmission mechanism includes a sprocket 8, a chain 9 and a driving wheel 10. There are two sprockets 8 and they are rotatably mounted on both sides of the upper end surface of the box body 5. The two sprockets 8 are connected by the chain 9. The driving wheel 10 is rotatably mounted on the upper end surface of the box body 5 and meshed with one of the sprockets 8. A plurality of cross bars 6 are mounted on the chain 9 and are evenly distributed along the circumference of the chain 9.

[0029] A motor is installed inside the box body 5, and the shaft end of the driving wheel 10 is connected to the output shaft of the motor. The motor drives the driving wheel 10 to rotate, thereby driving the sprocket 8 meshing with it to rotate. The transmission effect of the chain 9 is used to make the two sprockets 8 rotate synchronously, and the chain 9 drives the multiple cross bars 6 to rotate and enter the air cooling box 1;

[0030] When the cross bar 6 enters the air-cooling box 1, it will pass under the discharge port of the feeding tractor 2, and the rubber strip 7 will be placed on the cross bar 6, and then the rubber strip 7 will be transferred towards the discharge tractor 3. By repeating the cyclic operation and using the spacing between adjacent cross bars 6, the intermittent suspension of the rubber strip 7 is achieved, so that the rubber strip 7 is continuously arranged in a V shape in the air-cooling box 1, in order to increase the area of the rubber strip 7 in the air-cooling box 1, thereby increasing the contact area between the rubber strip 7 and the cold air, which is beneficial to improving the residual temperature cooling efficiency, and can also remove the residual water on the surface, and at the same time improve the working efficiency;

[0031] Further, the outer periphery of the chain 9 has a U-shaped frame. The upper and lower bottoms of the U-shaped frame are respectively connected to the upper and lower chain plates of adjacent chain links. The side edges of the U-shaped frame face outwards and are fixedly connected to the end face of the cross bar 6. The number of U-shaped frames is the same as and corresponds one-to-one with the number of cross bars 6, so as to install the cross bar 6 on the chain 9;

[0032] Further, the driving wheel 10 is an incomplete sprocket. The chain teeth on the outer periphery of the driving wheel 10 are continuous and the length is equal to the length of the chain link between adjacent cross bars 6;

[0033] Through the incomplete chain tooth structure of the driving wheel 10, when the driving wheel 10 rotates one circle, the sprocket 8 rotates a certain angle, and then the chain 9 drives the cross bar 6 to move a certain distance, realizing the replacement of the next cross bar 6 for the previous cross bar 6, ensuring that the length of the rubber strip segment between adjacent cross bars 6 is consistent, and realizing the continuous V-shaped arrangement of the rubber strip 7;

[0034] Specifically, a through groove 13 is provided on one side of the air-cooling box 1 close to the box body 5 along its length direction. The transmission mechanism drives a plurality of cross bars 6 to sequentially pass through the through groove 13 and enter the air-cooling box 1;

[0035] Further, the distance between the inner walls at both ends of the through groove 13 and the axis of the adjacent sprocket 8 is greater than the length of the cross bar 6, so as to ensure that the chain 9 can drive the cross bar 6 to smoothly pass through the through groove 13 and enter the air-cooling box 1;

[0036] Further, a roller 11 is rotatably installed at one end of the cross bar 6 away from the box body 5. A stabilizing plate 12 is installed on the inner wall of the air-cooling box 1 away from the box body 5. When the transmission mechanism drives the cross bar 6 in the air-cooling box 1 to move, the cross bar 6 drives the roller 11 to roll on the upper surface of the stabilizing plate 12, which can improve the stability of the cross bar 6, thereby improving the transmission stability of the rubber strip 7 in the air-cooling box 1;

[0037] Further, the height of the discharge port of the feeding tractor 2 and the height of the feeding port of the discharge tractor 3 are both greater than the height of the cross bar 6, so that when the cross bar 6 enters the air-cooling box 1, it can transfer the rubber strip 7 above, and it is also convenient to pull the rubber strip 7 out when the cross bar 6 exits the air-cooling box 1;

[0038] It should be noted that the feed tractor 2 discharges materials continuously, while the discharge tractor 3 discharges materials intermittently, and the working time of the discharge tractor 3 is consistent with the rotation time of the sprocket 8;

[0039] Specifically, evenly distributed air outlet nozzles are installed on the upper surface of the air outlet plate 4 , and the interior of the air outlet plate 4 has a cavity connected to the air outlet nozzles, and the cavity is connected to the air outlet of the external air blowing device.

[0040] In summary, the rubber strip cooling device proposed in the utility model transmits the water-cooled rubber strip 7 into the air-cooled box 1 through the feed tractor 2 and is pulled out by the discharge tractor 3. The rubber strip 7 is mounted on the cross bar 6. With the continuous traction of the feed tractor 2, the rubber strip 7 gradually droops at the feed end of the air-cooled box 1, and the transmission mechanism is used to drive multiple cross bars 6 to run, so that the cross bar 6 located outside the air-cooled box 1 passes through the through groove 13 into the air-cooled box 1, and pushes the upper rubber strip 7 in the direction of the discharge tractor 3, and the cycle operation is continued to realize the V-shaped continuous arrangement of the rubber strip 7 in the air-cooled box 1, increase the residence time and residence area of ​​the rubber strip 7 in the air-cooled box 1, thereby extending the air cooling area and duration of the air outlet plate 4 for the rubber strip 7, dissipating the residual temperature and residual water on the rubber strip 7, which is beneficial to improving the actual cooling effect and facilitating subsequent processing and storage operations.
