Description

Technical Field

[0001] This invention relates to the field of rubber parts processing technology, specifically to a gradient cooling and deburring device for rubber parts based on vulcanization waste heat recovery. Background Technology

[0002] During the vulcanization molding process of rubber products, overflow of rubber is inevitable at the parting surface of the mold, which will form burrs on the edge of the product. In order to ensure the appearance and size of the final product and the performance of specific parts, the burrs of the rubber parts must be removed.

[0003] The processing of rubber parts involves several processes with significant heat changes. For example, the vulcanization process emits a large amount of high-temperature waste gas, while subsequent cleaning processes require additional energy to heat the water bath. In traditional production lines, the heat energy of each process is isolated from each other, and there is a lack of an effective waste heat recovery mechanism, resulting in extremely low overall energy utilization rate of the entire line and high production energy consumption and costs.

[0004] Rubber at room temperature has extremely high flexibility and elasticity, making it difficult to effectively remove the very thin burrs on the edges of rubber parts through ordinary grinding processes. If the grinding time is simply extended in order to completely remove the burrs, the thicker critical parts of the rubber part will be damaged. Although some factories use liquid nitrogen to freeze the entire part for deburring, this is not only expensive, but it also makes the product body and the burrs brittle at the same time, which will cause the product body to break or be scrapped during grinding.

[0005] Most existing deburring equipment has only one function, and the deburring is treated by mechanical grinding alone. It lacks a pre-treatment mechanism to destroy the deburring before grinding. At the same time, the lack of continuous automated integration between the various modules of the equipment means that waste filtration and collection and finished product discharge often require manual intervention by stopping the machine, which seriously restricts the overall processing efficiency and continuous production capacity. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a gradient cooling and embrittlement deburring device for rubber parts based on vulcanization waste heat recovery. This device solves the problems of high energy consumption in traditional rubber parts production lines due to the ineffective utilization of waste heat from the vulcanization process, the difficulty in grinding and separating burrs at room temperature due to their flexibility, and the risk of damaging the product body when forcibly polished. It also addresses the low overall processing efficiency caused by the lack of a coherent pretreatment rupture mechanism and automated material collection and discharge in existing deburring processes.

[0016] The method of using the gradient chilling embrittlement and deburring device for rubber parts based on vulcanization waste heat recovery includes the following steps: S1. Using a gas-water heat exchanger installed on the branch pipe of the vulcanizing molding machine's exhaust system, the high-temperature waste gas heat energy released during the vulcanization process is captured and transferred to the washing and drying integrated machine as the heating source for the cleaning water bath. After the rubber parts have undergone the pre-vulcanization, punching and other processes, they enter the washing and drying integrated machine. High-temperature clean water is used to clean the rubber parts at high temperature, so that the rubber parts are in a high-temperature and humid state. The first motor is started, which drives the rotating plate to rotate. The sliding short column moves the sliding groove plate, which in turn drives the first rack rod to move linearly. The first rack rod drives the first sliding tube to slide on the outside of the connecting bend. The first rack rod drives the mounting gear to rotate, which drives the meshing second rack rod to move in the opposite direction, so that the second sliding tube slides in the opposite direction on the outside of the connecting bend, thereby adjusting the length of the chilling tunnel. The cleaned rubber parts enter the chilling tunnel, where dry and cold air is introduced to implement high pressure and local chilling, so that the extremely thin edge burrs first cross the glass transition temperature and become brittle, while the thicker product body still remains flexible and elastic, forming a gradient state of brittle outside and soft inside. S2. The rubber parts with temperature gradient enter the pretreatment mechanism in the processing box through the feeding bend. The motor is started, and the connecting rod is driven to deflect through the rotating rod and the connecting short column, which pulls the connecting plate to rotate. The distance and degree of compression between the two flexible rollers are adjusted. The second motor is started, and the driving bevel gear is driven to rotate through the rotating rod and spline shaft. The driven bevel gear drives the two flexible rollers to rotate in opposite directions. When the rubber parts pass between the two flexible rollers, they are subjected to flexible compression. The body deforms and recovers due to elasticity. The brittle burrs produce micro-cracks or break directly under the compression. The friction will push the brittle burrs lying on the surface backward. S3. The pre-treated rubber parts fall into the grinding machine through the hopper. Under the friction of the spherical grinding tools, the brittle and micro-cracked burrs quickly break apart and separate from the product body. The ground rubber parts and burr debris enter the feeding pipe together. The small burr waste falls into the waste box for collection through multiple filter grooves at the bottom of the feeding pipe. The cleaned rubber parts continue to slide down. The rubber parts with the burrs removed finally fall into the collection mechanism in the installation box and accumulate on the collection filter plate. The third motor is started, which drives the telescopic rod to extend and move the sliding cylinder to slide in the U-shaped slide groove. Pressing the collection filter plate causes it to flip and tilt, pouring the finished rubber product on the collection filter plate into the collection box.

[0017] This invention provides a gradient chilling and deburring device for rubber parts based on vulcanization waste heat recovery. It has the following beneficial effects: 1. This invention starts a first motor, which drives a rotating plate to rotate. The rotating plate moves a sliding groove plate via a sliding short column, which in turn drives a first rack rod to move linearly. The first rack rod drives a first sliding tube to slide outside the connecting bend, while simultaneously driving the mounting gear to rotate, causing the meshing second rack rod to move in the opposite direction, which in turn drives the second sliding tube to slide in the opposite direction outside the connecting bend. This allows for precise adjustment of the length of the chilling tunnel. After adjustment, the cleaned rubber parts enter the chilling tunnel, where the system introduces dry, cold air for high-pressure, localized chilling. This process causes the extremely thin edge burrs to drop below the glass transition temperature and become brittle, while the thicker product body retains good flexibility and elasticity, thus creating a physical gradient state of brittle exterior and soft interior on the product.

[0018] 2. This invention starts a motor, which drives the connecting rod to deflect through the rotating rod and connecting short column, thereby pulling the connecting plate to rotate. This adjusts the distance and compression degree between the two flexible rollers. The second motor is started, which drives the driving bevel gear to rotate through the rotating rod and spline shaft. Then, through the driven bevel gear, the two flexible rollers are driven to rotate in opposite directions. When the rubber part passes between the two flexible rollers, it will be subjected to flexible compression. The product body deforms due to its elasticity and quickly recovers. The brittle burrs will produce micro-cracks or break directly under the compression. The friction of the rollers will push the brittle burrs lying on the product surface backward, promoting the burrs to fall off.

[0019] 3. The small, rough edges of the waste material that fall off in this invention pass through multiple filter grooves at the bottom of the feed pipe and fall into the waste box for centralized collection. The cleaned and rough edges-removed rubber parts continue to slide down and fall into the collection mechanism inside the installation box, where they accumulate on the collection filter plate. The third motor is started, driving the telescopic rod to extend forward and move the sliding cylinder to slide in the U-shaped groove, pressing down on the collection filter plate to make it flip and tilt, thereby pouring the rubber products accumulated on the collection filter plate into the collection box for collection.

[0027] The method of using the gradient chilling embrittlement and deburring device for rubber parts based on vulcanization waste heat recovery includes the following steps: S1. By capturing the high-temperature exhaust gas heat energy released during the vulcanization process and transferring this heat energy to the washer-dryer 1 as a heating source for the cleaning water bath, the rubber parts, after undergoing pre-vulcanization and punching processes, enter the washer-dryer 1. High-temperature clean water is used to clean the rubber parts, placing them in a high-temperature and humid state. The first motor 21 is started, driving the rotating plate 23 to rotate. The sliding short column 28 moves the sliding groove plate 22, which in turn drives the first rack rod 210 to move linearly. The first rack rod 210 drives the first sliding groove plate 22 to move linearly. The moving tube 25 slides on the outside of the connecting bend 26. The first rack rod 210 drives the mounting gear 213 to rotate, which drives the meshing second rack rod 215 to move in the opposite direction, so that the second sliding tube 211 slides in the opposite direction on the outside of the connecting bend 26, thereby adjusting the length of the chilling tunnel. The cleaned rubber parts enter the chilling tunnel, and dry cold air is introduced to subject them to high pressure and local chilling, so that the extremely thin edge burrs first cross the glass transition temperature and become brittle, while the thicker product body still remains flexible and elastic, forming a gradient state of brittle outside and soft inside. S2. A rubber part with a temperature gradient enters the pretreatment mechanism 3 in the treatment box 32 through the feeding bend 11. The motor 37 is started, and the connecting rod 38 and the connecting short column 39 drive the connecting thin rod 310 to deflect, pulling the connecting plate 36 to rotate. The distance and degree of compression between the two flexible rollers 312 are adjusted. The second motor 31 is started, and the driving bevel gear 34 is driven to rotate through the rotating rod 33 and the spline shaft 35. The driven bevel gear 315 drives the two flexible rollers 312 to rotate in opposite directions. When the rubber part passes between the two flexible rollers 312, it is subjected to flexible compression. The body deforms and recovers due to elasticity. The brittle burrs produce micro-cracks or break directly under the compression. The friction will push the brittle burrs lying on the surface backward. S3. The pre-treated rubber parts fall into the grinding machine 15 through the hopper 14. Under the friction of the spherical grinding tool, the brittle and micro-cracked burrs quickly break apart and separate from the product body. The ground rubber parts and burr debris enter the feed pipe 5 together. The small burr waste falls into the waste box 7 through multiple filter grooves 6 at the bottom of the feed pipe 5 for collection. The cleaned rubber parts continue to slide down. The rubber parts with the burrs removed finally fall into the collection mechanism 4 in the mounting box 8 and accumulate on the collection filter plate 42. The third motor 43 is started, which drives the telescopic rod 44 to extend and drive the sliding cylinder 45 to slide in the U-shaped slide groove 47. The collection filter plate 42 is pressed and tilted, and the rubber finished product on the collection filter plate 42 is poured into the collection box 48.

10. A method for using a gradient cooling and deburring device for rubber parts based on vulcanization waste heat recovery, characterized in that, The gradient chilling and deburring device for rubber parts based on vulcanization waste heat recovery according to any one of claims 2-9 includes the following steps: S1. Using a gas-water heat exchanger installed on the branch pipe of the vulcanizing molding machine's exhaust system, the high-temperature exhaust gas heat energy released during the vulcanization process is captured and transferred to the washing and drying integrated machine (1) as the heating source for the cleaning water bath. After the rubber parts have undergone the previous vulcanization, punching and other processes, they enter the washing and drying integrated machine (1). The rubber parts are cleaned at high temperature using high-temperature clean water, so that the rubber parts are in a high-temperature and humid state. The first motor (21) is started, which drives the rotating plate (23) to rotate. The sliding short column (28) moves the sliding groove plate (22), which in turn drives the first rack rod (210) to move linearly. The rack rod (210) drives the first sliding tube (25) to slide on the outside of the connecting bend (26). The first rack rod (210) drives the mounting gear (213) to rotate, which drives the meshing second rack rod (215) to move in the opposite direction, so that the second sliding tube (211) slides in the opposite direction on the outside of the connecting bend (26), thereby adjusting the length of the chilling tunnel. The cleaned rubber parts enter the chilling tunnel, and dry cold air is introduced to apply high pressure and local chilling to them, so that the extremely thin edge burrs first cross the glass transition temperature and become brittle, while the thicker product body still remains flexible and elastic, forming a gradient state of brittle outside and soft inside. S2. The rubber parts with temperature gradient enter the pretreatment mechanism (3) in the treatment box (32) through the feeding bend (11). Start the motor (37), drive the connecting rod (310) to deflect through the rotating rod (38) and the connecting short column (39), pull the connecting plate (36) to rotate, adjust the distance and degree of compression between the two flexible rollers (312), start the second motor (31), drive the active bevel gear (34) to rotate through the rotating rod (33) and the spline shaft (35), drive the two flexible rollers (312) to rotate in opposite directions through the driven bevel gear (315), and the rubber parts are subjected to flexible compression when passing between the two flexible rollers (312). The body deforms and recovers due to elasticity. The brittle burrs produce micro-cracks or break directly under the compression. The friction will push the brittle burrs that have fallen on the surface back up. S3. The pre-treated rubber parts fall into the grinding machine (15) through the hopper (14). Under the friction of the spherical grinding tool, the brittle and micro-cracked burrs quickly break apart and separate from the product body. The rubber parts after grinding and the burr debris enter the feed pipe (5) together. The small burr waste falls into the waste box (7) through multiple filter grooves (6) at the bottom of the feed pipe (5) for collection. The cleaned rubber parts continue to slide down. The rubber parts with the burrs removed finally fall into the collection mechanism (4) in the mounting box (8) and accumulate on the collection filter plate (42). Start the third motor (43) to drive the telescopic rod (44) to extend and drive the sliding cylinder (45) to slide in the U-shaped chute (47). Press the collection filter plate (42) to flip and tilt, and pour the rubber finished product on the collection filter plate (42) into the collection box (48).
