[0001] The invention relates to the technical field of rubber cooling equipment, in particular to a cooling device for rubber production. Background Art

[0002] In the rubber production process, temperature control is a key factor affecting product quality, production efficiency and safety. After the rubber is melted and extruded, such as rubber belts and rubber strips, it needs to be water-cooled to inhibit the vulcanization reaction and avoid the formation of bubbles, holes or degradation of mechanical properties.

[0013] The cooling device for rubber production proposed by the present invention has the following beneficial effects:

[0014] 1. Through the cooperation of the second electric slide rail and the toggle slot, the limit structure can automatically achieve alternating left and right translation and lifting and lowering movements, eliminating the need for manual pulling of the rubber parts, significantly reducing labor intensity; the hydraulic cylinder of the limit structure is linked with the clamping table to automatically clamp the rubber parts and pull them into the cooling box, realizing full automation and improving production efficiency.

[0015] 2. The guide structure forms a curved bend. A pair of roller frames are raised and lowered by the first electric slide rail, driving the guide rollers to be arranged alternately, so that the rubber parts are interspersed with wavy curves in the cooling box. The same part contacts the cooling water multiple times, which prolongs the cooling time. The curved trajectory significantly increases the contact length between the rubber parts and the cooling water, avoiding the short-circuit problem of linear cooling and improving the cooling uniformity and effect.

[0016] 3. The spacing between the guide rollers can be flexibly controlled. By raising or lowering one of the roller frames, the spacing between the upper and lower guide rollers can be adjusted to accommodate rubber parts of different thicknesses or hardnesses. The tension can be controlled to prevent stretching and deformation. When the spacing is large, the rubber parts pass through loosely, extending the cooling time. When the spacing is small, the rubber parts pass through tightly, and combined with the rapid traction of the mobile structure, a balance can be achieved between efficiency and cooling effect.

[0017] 4. The bending of the rubber drives the liquid flow. 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.

[0018] 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, ensuring the cutting length accuracy and improving product consistency. The movement, guidance and limiting structures are linked to form an integrated process of pulling, cooling, bending and cutting. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following is a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings:

[0029] like Figures 1-8 As shown, the present invention provides a technical solution: a cooling and temperature reduction device for rubber production, comprising a cooling box 1, which is a rectangular box without an upper wall, and a guide port is opened in the middle of the top of the left and right side walls of the cooling box 1, and a drain valve 2 is connected to the middle of the bottom end of the front side wall of the cooling box 1, a guide structure 3 is provided on the front side of the cooling box 1, and a movable structure 4 is provided on the rear side wall of the cooling box 1, and a limiting structure 5 is fixedly provided on the movable structure 4, and the limiting structure 5 can be alternately lifted and lowered with the help of the movable structure 4; the cooling box 1 is used to carry cooling water, the guide structure 3 is used to carry the rubber parts to form a curve, the movable structure 4 is used to drive the limiting structure 5 to move, and the rubber parts are pulled by the limiting structure 5, and the rubber parts can also be cut by the limiting structure 5, and the limiting structure 5 can be driven by the movable structure 4 to move left and right and lift and lower along the toggle slot 6 for designed traction use.

[0030] As a further solution of the present invention, the guiding structure 3 includes a first electric slide rail 31, a slide rod 32, a pair of roller frames 33 and a plurality of guide rollers 34; the first electric slide rail 31 is vertically arranged on the lower inner wall of the cooling box 1 and is located on the right side of the center line of the front side wall of the cooling box 1, one end of the slide rod 32 is fixedly arranged on the lower inner wall of the cooling box 1 and close to the left side wall, one end of a pair of roller frames 33 is movably mounted on the slide rod 32, and the other ends of the roller frames 33 are respectively connected to the first electric slide rail 31, one of the roller frames 33 can be lifted and lowered above the other roller frame 33 through the first electric slide rail 31, and a plurality of guide rollers 34 are equidistantly and alternately movably arranged on the pair of roller frames 33; one of the roller frames 33 is driven to lift and lower by the first electric slide rail 31, and the spacing between the two roller frames 33 is adjusted to adjust the corresponding spacing of the guide rollers 34.

[0031] More specifically, the rubber parts pass through the guide rollers 34 in a wave-like manner, which prolongs the contact time with the cooling water and improves the cooling efficiency. By adjusting the spacing of the roller frames 33, it can adapt to rubber parts of different thicknesses and hardnesses, 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, so that the rubber belt is forced to pass back and forth through the guide rollers 34.

[0032] 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 provided on the front side of the moving opening 7. One end of the limit frame 41 is fixedly arranged at the top end of the rear side wall of the cooling box 1, and a curved toggle groove 6 is opened in the middle of the other end of the limit frame 41. The toggle groove 6 has peaks and troughs, and the peaks and troughs are equal-diameter arcs. The two ends of the toggle groove 6 are horizontally opposite to each other in a straight line. The second electric slide rail 42 is fixedly arranged on one end of the limit frame 41, and a movable second movable seat is provided on the second electric slide rail 42. The second movable seat on the second electric slide rail 42 movably passes through the moving opening 7 and is located on the front side of the rear side wall of the cooling box 1. The lifting frame 43 is T-shaped, and one end of the lifting frame 43 is fixedly connected to the second electric slide rail 42. The lifting frame 43 is driven to move left and right by the second electric slide 42, so that the roller 48 is forced to move along the toggle groove 6, thereby driving the lifting seat 45 to move up and down in the lifting frame 43 and performing a reset assist with the help of the first spring 46.

[0033] More specifically, through the horizontal movement of the second electric slide rail 42 and the curve constraint of the toggle slot 6, the limiting structure 5 can synchronously realize the compound movement of left and right translation and up and down lifting, forming a "curved peak and trough" traction trajectory, 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 peak and trough are converted. The equal-diameter arc design of the toggle slot 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.

[0034] 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 in front of the limiting frame 41, one end of the pair of hydraulic cylinders 52 is fixedly embedded in the upper walls of 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 movable through the limiting seat 51 is at the top left side, and the mounting rods 54 correspond to the hydraulic cylinders 52 respectively. The clamping platform 55 is fixedly arranged between the pair of mounting rods 54. A pair of second springs 56 are movably mounted on the mounting rods 54 and are located below the clamping platform 55. The pair of second springs 56 can support the clamping platform 55. The cutter 57 is fixedly arranged on the upper wall of the limit seat 51 and is located between the clamping platform 55 and the hydraulic cylinder 52. The upper pressure plate 53 is driven to descend by the hydraulic cylinder 52 to cooperate with the clamping platform 55 for clamping. The upper pressure plate 53 continues to descend, prompting the clamping platform 55 to be forced to descend with the help of the mounting rods 54, and the cutter 57 can be used to apply force for cutting.

[0035] As a further solution of the present invention, the limiting structure 5 can clamp and cut the rubber belt, and 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.

[0036] 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.

[0037] More specifically, the clamping-cutting action of the limiting structure 5 is synchronized 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. The clamping and cutting functions are integrated into the same structure, reducing the space occupied by the equipment and improving the compactness of the production line.

[0038] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific operations are as follows.

[0039] S1. Fill the cooling box 1 with clean water, which can be drained through the drain valve 2 for replacement;

[0040] S12, using the second electric slide rail 42 in the movable structure 4 and the movable opening 7, the limiting structure 5 is moved to the left end of the cooling box 1 and the toggle slot 6 is used to enable the limiting structure 5 to be positioned above the water level;

[0041] 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 be clamped and fixed by lowering the upper pressure plate 53; then drive the second electric slide rail 42 to drive the limiting structure 5 to move to the right. 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. When the lifting seat 45 is forced to descend in the lifting frame 43, it compresses the first spring 46, and when it rises, it is assisted by the first spring 46. The driving of the second electric slide rail 42 drives the lifting frame 43 to move through the fitting opening 8;

[0042] 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 alternately pass through the corresponding guide rollers 34, causing the rubber belt to be located in the cooling box 1 to form a curved wave shape and be immersed in the water for cooling;

[0043] S15, the guide rollers 34 on the two roller frames 33 are alternately arranged, and the first electric slide rail 31 is driven to move the two roller frames 33 up and down on the slide bar 32 to adjust the spacing, thereby adjusting the high point position of the rubber belt passing through the guide rollers 34, and reciprocatingly driving one of the roller frames 33 up and down to achieve the curve bending change after the rubber belt passes through, thereby stirring the internal liquid and promoting the flow of the cooling liquid;

[0044] 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 and be cut, and the clamping platform 55 can be reset with the help of the second spring 56.
