Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tire processing, specifically a tire rubber release agent coating device. Background Technology
[0002] Tires are automotive parts made of rubber, carbon black, sulfur, steel wire, fiber cord, etc. In the tire production process, there is a process called vulcanization. The current common vulcanization process is to put the tire blank into a high-temperature mold, fill the inside of the tire blank with a high-temperature and high-pressure medium through a capsule, heat and pressurize the tire blank, and squeeze the tire blank onto the mold to solidify and shape it into the final product.
[0003] To ensure proper separation of the vulcanized bladder from the finished tire after vulcanization, a liquid release agent needs to be coated onto the inner surface of the tire blank. Traditional methods for applying the release agent include manual spraying, smearing, or immersion. Manual operation makes it difficult to achieve uniform spraying speed, easily leading to uneven application of the release agent. Smearing requires manual application of the release agent into the cavities of each mold, which is labor-intensive. Immersion involves immersing the rubber sheet into the release agent, allowing it to adhere evenly within the cavity. However, immersion makes it difficult to control the thickness of the release agent, easily resulting in excessive application. This not only makes it difficult to dry, affecting product quality in subsequent processes, but also makes cleaning the release agent from the tire surface more time-consuming and labor-intensive. Utility Model Content
[0004] To solve the above problems, namely the problems mentioned in the background art, this utility model proposes a tire rubber release agent coating device, which includes a base column and a turntable. The lower part of the base column is provided with a pair of snap-fit components, and the upper part of the base column is provided with a mounting groove. A motor is installed in the mounting groove. The output end of the motor passes through the base column and is fixedly connected to the turntable. A lifting component is installed on the upper side of the turntable, and a disc is installed on the lifting component. A coating structure is installed on the outer side of the disc.
[0005] The coating structure includes a rotary joint, an annular liquid tube, a pair of inclined rods, a pair of liquid tubes, a pair of application brushes, and a pair of curved tubes;
[0006] The annular liquid tube is placed on the upper side of the disc. The rotating end of the rotary joint is fixedly connected to the liquid inlet end of the annular liquid tube. The two ends of the disc are respectively fixedly connected to corresponding inclined rods. The lower ends of the pair of inclined rods are respectively fixedly connected to corresponding applicators. The other two ends of the disc are respectively fixedly connected to corresponding liquid tubes. The lower ends of the pair of liquid tubes are respectively fixedly connected to corresponding arc tubes. The outer sides of the pair of arc tubes are respectively fixedly connected to a set of evenly arranged nozzles. The pair of inclined rods and the pair of liquid tubes are staggered. The upper ends of the pair of liquid tubes are connected to the annular liquid tube through corresponding flexible hoses.
[0007] A further feature of this invention is that a pair of the snap-fit components includes a pair of springs, a pair of guide rods, and a pair of arc-shaped plates;
[0008] The base column has symmetrical grooves at its lower part, and corresponding guide holes are provided on the lower parts of both sides of the base column. A pair of grooves are connected to the corresponding guide holes. A pair of springs are respectively placed in the corresponding grooves. One end of a pair of guide rods passes through the corresponding guide holes and is fixedly connected to the corresponding springs. The other end of a pair of guide rods is fixedly connected to the corresponding arc-shaped plates.
[0009] A further feature of this invention is that the lifting assembly includes a hydraulic cylinder, a pair of sleeves, and a pair of slide rods;
[0010] The hydraulic cylinder is mounted on the upper side of the turntable, and the output end of the hydraulic cylinder is fixedly connected to the lower side of the turntable. The two ends of the lower side of the turntable are respectively fixedly connected to the corresponding sliding rods. The lower ends of a pair of sliding rods are respectively slidably mounted in the corresponding sleeves, and a pair of sleeves are fixedly connected to the upper side of the turntable.
[0011] A further feature of this invention is that the pair of application brushes are matched with the cross-section of the tire mold cavity, and both application brushes are soft and elastic brushes. The brushes can be made of nylon or polyurethane material, and the brush bristles are more resilient, making it easier to uniformly coat the concave and convex surfaces inside the cavity.
[0012] A further feature of this invention is that the lower parts of both of the arc-shaped plates are sloped, which facilitates their insertion into the cylinder of the tire mold.
[0013] A further feature of this invention is that the motor is a slow-speed motor.
[0014] The beneficial technical effects of this utility model are as follows: This utility model uses a pair of snap-fit components to fix the base column inside the cylinder of the tire mold, so that the device remains stable during operation. After the device is fixed, a pair of application brushes and a pair of arc tubes are lowered into the cavity through a lifting component. When the lower side of the pair of application brushes is slightly and tightly attached to the inner wall of the cavity, the descent stops and the device is started. The device sprays the release agent evenly into the cavity through the rotation of the arc tubes, and then coats the release agent evenly into the cavity through the rotation of the pair of application brushes. Since the application brushes are soft brushes, they can also be evenly coated on the concave and convex surfaces inside the cavity, replacing manual operation and avoiding uneven coating. At the same time, it avoids the situation of excessive release agent in the cavity, reducing the amount of release agent used and avoiding the problem of difficult drying caused by excessive release agent.

[0019] The following is a reference to the appendix. Figures 1-3 The preferred embodiments of this utility model are described below. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.
[0020] This invention discloses a tire rubber release agent coating device. Before use, a pair of springs 9 are in a naturally stretched state, a pair of arc-shaped plates 10 are in the position of maximum relative distance, and the disc 2 is in the highest position. When using this device, the lower end of the base column is passed through the cylinder of the tire mold 8, and the pair of arc-shaped plates 10 are pushed towards each other. The pair of arc-shaped plates 10 drive the corresponding guide rods to slide towards each other, and the pair of guide rods push the corresponding springs 9 into a compressed state. When the lower slope of the pair of arc-shaped plates 10 extends into the upper opening of the cylinder, the pair of arc-shaped plates 10 are released, and the base column is pushed downward. Under the action of the rebound force of the pair of springs 9, the pair of arc-shaped plates 10... The curved surface of plate 10 slides downward along the inner wall of the cylinder. When the lower side of turntable 15 is in contact with the upper end of the cylinder of tire mold 8, the downward push of the base column stops. A pair of spring-loaded springs 9 always push against the corresponding curved plate 10. The pair of curved plates 10 fix the base column inside the cylinder of tire mold 8, keeping the device stable during operation. The hydraulic cylinder 6 is activated, and the output end of the hydraulic cylinder 6 retracts, causing the disc 2 to slide downward. The disc 2 drives a pair of sliding rods 5 to slide downward along the corresponding sleeve 12. The disc 2 drives a pair of applicator brushes 7 and a pair of curved tubes 14 to slide downward into the cavity through a pair of inclined rods 1 and a pair of liquid pipes 14. When the lower side of the pair of applicator brushes 7 is slightly and tightly in contact with the inner wall of the cavity, Close hydraulic cylinder 6, fix the upper end of rotary joint 3 to the external liquid pump, start the external liquid pump and motor 11. The external liquid pump slowly pumps the required amount of film release agent into the annular liquid tube 4. The film release agent in the annular liquid tube 4 is pumped into a pair of liquid tubes 14. The film release agent in the pair of liquid tubes 14 is pumped into the corresponding arc tubes 13. The film release agent in the pair of arc tubes 13 is evenly sprayed into the cavity through a corresponding set of nozzles. At the same time, motor 11 drives turntable 15 to rotate, turntable 15 drives coating structure to rotate, and a pair of application brushes 7 and a pair of arc tubes 13 slide in a circular trajectory in the cavity. The film release agent is evenly sprayed into the cavity through the sliding of the pair of arc tubes 13. The film release agent is evenly sprayed into the cavity, and then a pair of applicator brushes 7 slide along the inner wall of the cavity to evenly apply the film release agent. Since the applicator brushes 7 are soft and resilient brushes, they can also evenly coat the uneven surfaces inside the cavity. After all the film release agent has been sprayed out, the external liquid pump is turned off. The pair of applicator brushes 7 continue to slide until the film release agent is evenly coated. Then, the motor 11 is turned off, and the device can be removed. This device replaces manual operation, avoids uneven coating, and avoids excessive release agent in the immersion cavity. This device reduces the amount of release agent used and avoids the drying difficulties caused by excessive release agent.
