BRIEF DESCRIPTION OF DRAWINGS
[0015] Fig. 1 is a top view of the present application; Fig. 2 is a bottom view of the present application. DETAILED DESCRIPTION
[0016] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings.
[0017] Reference Figs. 1-2A cooling device for a sealing strip includes a cooling tank 1. Several partitions 11 are spaced apart along the length of the cooling tank 1, dividing the interior of the cooling tank 1 into several cooling zones 12. Each partition 11 has an opening 13 that connects two adjacent cooling zones 12. A first drive roller 2 is provided at the inlet end of the cooling tank 1 to guide the sealing strip into the cooling tank 1, and a second drive roller 3 is provided at the outlet end of the cooling tank 1 to guide the sealing strip out of the cooling tank 1. Several guide rollers 4 are rotatably connected within the cooling tank 1. A flow guiding mechanism 5 is provided within the cooling tank 1 to circulate the coolant within the cooling tank 1. In this way, the partitions 11 divide the cooling tank 1 into multiple cooling zones 12, and the openings 13 on the partitions 11 allow the coolant to circulate in different areas within the cooling tank 1. Simultaneously, the flow guiding mechanism 5 promotes overall flow of the coolant, avoiding uneven cooling caused by localized stagnation of the coolant.
[0018] In this design, the flow guiding mechanism 5 includes a rotating shaft 51 disposed within the cooling tank 1, a first drive motor 52 disposed on the side wall of the cooling tank 1 and capable of driving the rotating shaft 51 to rotate, and several flow guiding plates 53 disposed on the outside of the rotating shaft 51. The first drive motor 52 drives the rotating shaft 51 to rotate, which in turn drives the flow guiding plates 53 on the rotating shaft 51 to rotate synchronously, thereby promoting a regular circulation of the coolant within the cooling tank 1. This prevents localized stagnation of the coolant, ensuring that the coolant temperature in each area remains relatively uniform. This, in turn, guarantees uniform cooling of all parts of the sealing strip, preventing problems such as deformation and performance differences in the sealing strip caused by uneven cooling.
[0019] In this design, the guide roller 4 includes first guide rollers 41 disposed at the front and rear ends of the cooling tank 1, and several second guide rollers 42 disposed between the front and rear first guide rollers 41. The height of the second guide rollers 42 is lower than the height of the first guide rollers 41. The second guide rollers 42 are at a certain height relative to the bottom of the cooling tank 1 to allow the sealing strip to pass through. This allows the sealing strip to travel in an S-shaped path within the cooling tank 1, effectively extending the contact time between the sealing strip and the coolant, ensuring that the sealing strip can be fully cooled, and improving cooling efficiency and effect. Preferably, the height of the rotating shaft 51 is higher than the height of the second guide rollers 42, and there are at least two second guide rollers 42. The rotating shaft 51 is disposed between the two second guide rollers 42. By displacing the rotating shaft 51 between the two second guide rollers 42 and at a height higher than the second guide rollers 42, the coolant pushed by the flow guiding mechanism 5 can directly act on the area around the sealing strip, accelerating the renewal of coolant on the surface of the sealing strip, improving heat exchange efficiency, and preventing interference between the flow guiding plate 53 and the sealing strip.
[0020] In this design, the height of the guide roller 4 and the rotating shaft 51 is not higher than the height of the top surface of the partition plate 11. The upper end of the partition plate 11 is provided with a groove 14 through which the guide roller 4 and the rotating shaft 51 can pass, thereby ensuring that the coolant can completely submerge the sealing strip, the guide roller 4 and the rotating shaft 51, so that the sealing strip can fully contact the coolant, thereby ensuring the cooling effect and the flow guiding effect.
[0021] In this case, an auxiliary drive roller 6 is provided at the inlet end of the cooling tank 1 and behind the first drive roller 2. A spacer 7 is sleeved between the first drive roller 2 and the auxiliary roller. A second drive motor 8 is provided on the cooling tank 1 to drive the first drive roller 2 to rotate. In this way, the spacer 7 can prevent the freshly extruded sealing strip from sticking to the first drive roller 2, and by placing the spacer 7 on the first drive roller 2 and the auxiliary roller, it can be ensured that there is sufficient traction force to pull the sealing strip into the cooling tank 1.
[0022] In this design, the outlet end of the cooling tank 1 is provided with an upwardly extending support frame 15. The second drive roller 3 is disposed on the upper end of the support frame 15. The support frame 15 is provided with a third drive motor 9 that can drive the second drive roller 3 to rotate. The surface of the second drive roller 3 is covered with rubber and has anti-slip texture. This arrangement of the second drive roller 3 above the cooling tank 1 prevents it from carrying too much coolant out and dripping onto the ground, causing pollution. Furthermore, the support frame 15, located below the second drive roller 3, is provided with several fans 10 for drying the sealing strips. Each fan 10 corresponds to one of the cooling zones 12. This further dries the sealing strips by the fans 10, preventing oxidation, adhesion, or interference with subsequent processing steps caused by coolant residue. Specifically, the support frame 15 is triangular, and the fans 10 are disposed on the inclined side of the support frame 15, which facilitates the drying of the sealing strips by the fans 10.
[0023] In this design, a first through hole 101 is provided at the bottom and on the front side of the cooling tank 1, and a second through hole 102 is provided at the bottom and on the rear side of the cooling tank 1. A circulating water pipe 103 is provided between the first through hole 101 and the second through hole 102 to connect the two. A centrifugal pump 104 is provided on the circulating water pipe 103 to guide the coolant from the first through hole 101 to the second through hole 102. Thus, the circulation system composed of the first through hole 101, the second through hole 102, the circulating water pipe 103, and the centrifugal pump 104 achieves forced circulation of the coolant. At the same time, the design of this circulation system allows the coolant to form an overall flow trend within the cooling tank 1. In conjunction with the flow guiding mechanism 5, this further improves the uniformity of coolant flow and ensures consistent cooling effect across all parts of the sealing strip. Furthermore, a filter can be added to the circulating water pipe 103 to effectively filter impurities in the coolant, ensure the cleanliness of the coolant, prevent impurities from scratching the surface of the sealing strip, extend the service life of each component of the device, and reduce water waste and production costs through the recycling of coolant, which meets the requirements of energy conservation and environmental protection.
[0024] In this design, the cooling tank 1 has an inlet 105 at its bottom and front, and a drain 106 at its bottom and rear. An inlet pipe 107 is connected to the inlet 105, and a drain pipe 108 is connected to the drain 106. Both the inlet pipe 107 and the drain pipe 108 are equipped with control valves to regulate their opening and closing. This design facilitates the replenishment of coolant to the cooling tank 1 by the inlet 105 and inlet pipe 107, ensuring a sufficient coolant level and good cooling performance. The drain 106 and drain pipe 108 facilitate the discharge of used coolant or its replacement, preventing coolant deterioration from affecting cooling efficiency and product quality.
[0025] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
