The curved rubber parts bend back and forth between the guide rollers, passively stirring the water in the cooling box, forming local convection, breaking the dead water area, and improving the heat exchange efficiency of the cooling water.

[0016] 5. The limiting structure has a built-in cutter. After clamping the rubber part, the clamping table descends to the bottom of the cutter and precise cutting is achieved through the thrust of the hydraulic cylinder. No separate cutting equipment is required, which reduces the process connection time. The moving structure can pull the rubber part to the specified position and then automatically cut it off to ensure the cutting length accuracy and improve product consistency. Through the linkage of the moving, guiding and limiting structures, an integrated process of pulling, cooling, bending and cutting is formed. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] More specifically, the rubber parts travel in a wave-like manner between the guide rollers 34, thereby extending the contact time with the cooling water and improving the cooling efficiency. The spacing between the roller frames 33 is adjusted to accommodate rubber parts of different thicknesses and hardnesses, thereby avoiding breakage or deformation caused by uneven tension during traction. The guide rollers 34 are respectively opposite to the middle parts of the crests and troughs of the toggle grooves 6, so that the rubber belt is pulled alternately on the guide rollers 34 for corresponding fit, thereby causing the rubber belt to be forced to reciprocate through the guide rollers 34.

[0022] As a further solution of the present invention, the movable structure 4 includes a limit frame 41, a second electric slide rail 42, a lifting frame 43, a lifting rod 44, a lifting seat 45, a first spring 46, a connecting shaft 47 and a sleeve roller 48; the limit frame 41 is L-shaped, and a moving opening 7 is opened at one end of the limit frame 41, and a fitting opening 8 is arranged on the front side of the moving opening 7.

[0023] More specifically, through the horizontal movement of the second electric slide rail 42 and the curve constraint of the toggle groove 6, the limiting structure 5 can synchronously realize the compound movement of left and right translation and up and down lifting, forming a "curved wave peak and trough" traction trajectory, thereby avoiding insufficient cooling caused by the linear movement of the rubber part. The first spring 46 can absorb the impact load of the sleeve roller 48 when the wave peak and wave trough are converted. The equal-diameter arc design of the toggle groove 6 ensures that the movement curvature of the sleeve roller 48 is consistent, so that the bending amplitude of the rubber part is uniform, and the cooling consistency is improved.

[0024] As a further solution of the present invention, the limiting structure 5 includes a limiting seat 51, a pair of hydraulic cylinders 52, an upper pressure plate 53, a pair of mounting rods 54, a clamping platform 55, a pair of second springs 56 and a cutter 57; the limiting seat 51 is an inverted F-type, one end of the limiting seat 51 is fixedly arranged on the other end of the connecting shaft 47 and is located on the front side of the limiting frame 41, one end of the pair of hydraulic cylinders 52 is respectively fixedly embedded in the upper walls at the front and rear ends of the limiting seat 51, the upper pressure plate 53 is fixedly arranged between the telescopic ends of the pair of hydraulic cylinders 52, and the upper pressure plate 53 is opposite to the limiting seat 51, and one end of a pair of mounting rods 54 is respectively movable through the limiting seat 51.

[0025] As a further solution of the present invention, the limiting structure 5 can clamp and cut the rubber belt, the clamping platform 55 is located above the cutter 57, and the clamping platform 55 can be lowered to below the cutter 57 for design and use requirements.

[0026] As a further solution of the present invention, the upper pressing plate 53 is raised and lowered by the hydraulic cylinder 52, and the upper pressing plate 53 descends and contacts the clamping platform 55 first, which is used for design traction.

[0027] More specifically, the clamping and cutting action of the limiting structure 5 is synchronously linked with the traction movement of the movable structure 4, and the second spring 56 realizes "soft contact" clamping, which is suitable for thin-walled or easily deformed rubber parts; the cutter 57 is fixed in position and cooperates with the vertical movement of the clamping table 55.

[0028] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0029] S1. Fill the cooling box 1 with clean water, which can be drained through the drain valve 2 for replacement; S12, by means of the second electric slide rail 42 in the moving structure 4, the limiting structure 5 is moved to the left end of the cooling box 1 by means of the moving opening 7, and the limiting structure 5 is positioned above the water level by means of the toggle slot 6; S13, drive the hydraulic cylinder 52 to raise the upper pressure plate 53, so that the rubber belt can pass through the clamping platform 55, and clamp and fix it by lowering the upper pressure plate 53; then drive the second electric slide to drive the limiting structure 5 to move rightward, and during the movement, the sleeve roller 48 is forced to roll in the toggle groove 6 and move along the toggle groove 6, thereby driving the limiting structure 5 on the connecting shaft 47 to move and rise and fall along the toggle groove 6 under the limiting action of the lifting seat 45, and the lifting seat 45 is forced to compress the first spring 46 when descending in the lifting frame 43, and is assisted by the first spring 46 when rising, and the driving of the second electric slide rail 42 drives the lifting frame 43 to move through the fitting opening 8; S14, the limiting structure 5 moves along the curve of the toggle groove 6, pulling one end of the rubber belt along the curve, causing the rubber belt to reciprocate and alternately pass through the corresponding guide rollers 34, causing the rubber belt to be located in the cooling box 1, forming a curved wave shape and immersed in water for cooling; S15, the guide rollers 34 on the two roller frames 33 are arranged alternately, and the two roller frames 33 can be raised and lowered on the slide bar 32 to adjust the spacing through the driving of the first electric slide rail 31, thereby adjusting the high point position of the rubber belt passing through the guide rollers 34, and one of the roller frames 33 can be reciprocatingly driven to rise and fall, so as to achieve the curve bending change after the rubber belt passes through to stir the internal liquid and promote the flow of the cooling liquid; S16. When the hydraulic cylinder 52 is continuously driven to contract, the continuous descent of the upper pressure plate 53 will apply force to the clamping platform 55. The clamping platform 55 is forced to descend and compress the second spring 56 on the mounting rod 54. As the clamping platform 55 descends, the rubber belt will contact the cutter 57 to be cut, and the clamping platform 55 can be reset with the help of the second spring 56.
