Description

Technical Field

[0001] This utility model belongs to the field of automotive parts manufacturing, specifically a spraying device for tire self-healing coating. Background Technology

[0002] With the booming development of the automotive industry, consumers are paying increasing attention to the safety and reliability of automobiles. As a key component of automobiles, tires directly affect the safety, comfort and durability of automobiles.

[0003] Traditional tires are prone to leaks and blowouts when punctured by sharp objects, which not only poses a great threat to driving safety but also increases vehicle repair costs and time. As a result, the demand for tires with self-healing functions continues to rise. To meet this market demand, tire manufacturers need efficient and precise spraying equipment to mass-produce high-quality self-healing tires, thereby gaining an advantage in the fierce market competition.

[0004] Traditional tire self-healing coating spraying devices have a limited number of nozzles, resulting in a small spraying area per pass and uneven coating coverage. Therefore, this invention provides a spraying device for tire self-healing coatings. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A spraying device for tire self-healing coating, comprising a processing chamber; a cylinder fixedly connected to one side of the processing chamber; a glass door slidably connected to the outer wall of the processing chamber; a paint storage device fixedly connected to the output end of the cylinder; a telescopic nozzle fixedly connected to one side of the paint storage device; the telescopic nozzle fixedly connected to the side near the tire; a Y-shaped nozzle installed at the end of the telescopic nozzle; a set of rotary motors fixedly connected to one side of the processing chamber; a rotating rod fixedly connected to the output end of the rotary motors; the end of the rotating rods rotatably connected to the inner wall of the processing chamber. During operation, the glass door is slid to the side away from the tire, the tire to be sprayed is vertically placed between the rotating rods, the motor is started, causing its output end to rotate, thus rotating the rotating rods. The tire is rotated by the friction generated by the rotation of the rotating rod and its contact with the tire surface. Then, the output end of the cylinder is controlled to extend the paint storage device into the tire's interior. The telescopic nozzle is then extended to the spray range of the Y-shaped nozzle. The paint storage device is then switched on, and the self-healing paint inside is sprayed out of the Y-shaped nozzle through the telescopic nozzle. Using a cylinder allows for quick and accurate positioning, reducing travel time. The telescopic nozzle brings the nozzle closer to the tire's inner surface, reducing paint splashing and waste. The Y-shaped nozzle on the telescopic nozzle provides a wider spray angle and coverage area. The special structure of the Y-shaped nozzle disperses the paint into finer particles, ensuring even adhesion to the tire's inner surface, improving coating quality and aesthetics, and reducing drips and missed areas.

[0007] Preferably, the processing chamber has grooves on both sides; the two grooves are correspondingly arranged; a linear motor is fixedly connected to the middle of the groove; a support column is fixedly connected to the load end of the linear motor; a sleeve is rotatably connected to the outside of the support column; a bearing is installed between the sleeve and the support column, and the cooperation between the sleeve and the rotating rod makes the contact point with the tire form a triangle. By utilizing the unique stability of the triangle, the tire's bounce amplitude is reduced during rotation, increasing the stability during spraying.

[0008] Preferably, air pumps are fixedly connected to both sides of the paint storage device; an air jet pipe is fixedly connected to the output end of the air pump; the air jet pipe and the Y-shaped nozzle are arranged in the same direction. By setting the air pump, the paint on the inner surface of the tire can be solidified and quickly set, reducing the occurrence of sagging and dripping. At the same time, it can separate dust from the inner surface of the tire, thereby enhancing the adhesion between the coating and the inner surface of the tire. This makes the coating less prone to peeling or flaking during use, enhancing the stability and protective effect of the coating.

[0009] Preferably, a set of bases is fixedly connected to both sides of the paint storage device; an infrared heating tube is installed between the bases; a set of focusing plates is fixedly connected to both sides of the paint storage device; the focusing plates are arranged on both sides of the infrared heating tubes, which can quickly generate heat, causing the sprayed coating to heat up quickly, shortening the drying time. Infrared rays have high penetrability and can penetrate deep into the coating, allowing the paint to evaporate and cure faster, reducing the situation of surface drying while internal moisture may occur with traditional heating, and improving drying efficiency.

[0010] Preferably, the processing chamber is provided with a ventilation opening; the ventilation opening is connected to an exhaust pipe; the other end of the exhaust pipe is fixedly connected to an air pump. The exhaust pipe can remove paint particles floating in the air, reduce the accumulation of paint particles in the processing chamber, keep the processing chamber clean, reduce the interference of dust on the uniformity and adhesion of the coating, and enable the coating to achieve a high quality.

[0011] Preferably, a collection trough is provided at the bottom of the processing chamber; the collection trough is located directly below the telescopic nozzle, and the collection trough can collect the paint that has not been sprayed onto the inner surface of the tire, which is convenient for transportation or reuse and can also keep the inside of the processing chamber clean.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The spraying device for tire self-healing coating described in this utility model can quickly and accurately reach the designated position by using a cylinder, shortening the movement time. The telescopic nozzle can bring the spray head closer to the inner surface of the tire, reducing paint splashing to the outside of the tire and causing waste. The Y-shaped nozzle installed on the telescopic nozzle can make the spray angle larger and the coverage area wider. The special structure of the Y-shaped nozzle can disperse the paint into finer particles, so that the paint is evenly adhered to the inner surface of the tire, improving the quality and aesthetics of the coating and reducing phenomena such as sagging and missed spraying.

[0014] 2. The spraying device for tire self-healing coating described in this utility model can quickly generate heat by installing an infrared heating tube, which can quickly heat up the sprayed coating, shorten the drying time, and the infrared rays have high penetrability and can penetrate into the interior of the coating, so that the coating can evaporate and cure faster, reducing the situation of surface drying and internal dampness that may occur with traditional heating, and improving drying efficiency.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 3As shown, this utility model discloses a spraying device for tire self-healing coating, comprising a processing chamber 1; a cylinder 11 is fixedly connected to one side of the processing chamber 1; a glass door 17 is slidably connected to the outer wall of the processing chamber 1; a paint storage device 12 is fixedly connected to the output end of the cylinder 11; a telescopic nozzle 13 is fixedly connected to one side of the paint storage device 12; the telescopic nozzle 13 is fixedly connected to the side near the tire; a Y-shaped nozzle 14 is installed at the end of the telescopic nozzle 13; a set of rotary motors 15 is fixedly connected to one side of the processing chamber 1; a rotating rod 16 is fixedly connected to the output end of the rotary motor 15; the end of the rotating rod 16 is rotatably connected to the inner wall of the processing chamber 1. During operation, the glass door 17 is slid to the side away from the tire, the tire to be sprayed is vertically placed between the set of rotating rods 16, the rotary motor 15 is started, causing its output end to rotate, driving the rotating rod 16 to rotate, utilizing the rotation... The friction generated by the rotation of rod 16 and its contact with the tire surface causes the tire to rotate. Then, the output end of the control cylinder 11 drives the paint storage device 12 to extend into the tire. Then, the telescopic nozzle 13 is extended to the spray range of the Y-type nozzle 14. The switch of the paint storage device 12 is turned on, and the self-healing paint inside the paint storage device 12 is sprayed out from the Y-type nozzle 14 through the telescopic nozzle 13. Using the cylinder 11, the target position can be reached quickly and accurately, shortening the movement time. The telescopic nozzle 13 allows the nozzle to be closer to the inner surface of the tire, reducing paint splashing to the outside of the tire and causing waste. Installing the Y-type nozzle 14 on the telescopic nozzle 13 allows for a larger spray angle and a wider coverage area. The special structure of the Y-type nozzle 14 can disperse the paint into finer particles, allowing the paint to adhere evenly to the inner surface of the tire, improving the quality and aesthetics of the coating, and reducing phenomena such as sagging and missed spraying.

[0024] like Figure 1 and Figure 4 As shown, the processing chamber 1 has sliding grooves 2 on both sides; the sliding grooves 2 on both sides are correspondingly arranged; a linear motor 21 is fixedly connected to the middle of the sliding groove 2; a support column 22 is fixedly connected to the load end of the linear motor 21; a sleeve 23 is rotatably connected to the outside of the support column 22; a bearing is installed between the sleeve 23 and the support column 22. During operation, after the tire rotates, the linear motor 21 is controlled to slide in the middle of the sliding groove 2, driving the support column 22 to make the sleeve 23 contact the tire surface. Because a bearing is installed, the sleeve 23 can rotate, thereby achieving a fixing effect. Through the cooperation between the sleeve 23 and the rotating rod 16, the point of contact with the tire forms a triangle. Utilizing the unique stability of the triangle, the tire's bounce amplitude is reduced during rotation, increasing the stability during spraying.

[0025] like Figure 2 , Figure 3 and Figure 5As shown, an air pump 3 is fixedly connected to the paint storage device 12; an air jet pipe 31 is fixedly connected to the output end of the air pump 3; the air jet pipe 31 and the Y-type nozzle 14 are arranged in the same direction. When working, the air pump 3 is turned on, so that the gas is sprayed out along the air jet pipe 31 and reaches the inner surface of the tire. By setting the air pump 3, the paint on the inner surface of the tire can be condensed and set more quickly, reducing the occurrence of sagging and dripping. At the same time, it can separate the dust on the inner surface of the tire, thereby enhancing the adhesion between the coating and the inner surface of the tire, and enhancing the stability and protective effect of the coating.

[0026] like Figure 3 and Figure 5 As shown, a set of bases 4 are fixedly connected to both sides of the paint storage device 12; an infrared heating tube 41 is installed between the bases 4; a set of focusing plates 42 are fixedly connected to both sides of the paint storage device 12; the focusing plates 42 are arranged on both sides of the infrared heating tubes 41. When working, the infrared heating tubes 41 are turned on, and the light will radiate in all directions. The focusing plates 42 irradiate the sprayed coating with the radiant light. The infrared heating tubes 41 can generate heat quickly, so that the sprayed coating can heat up quickly, shorten the drying time. Infrared rays have high penetrability and can penetrate into the interior of the coating, so that the paint can evaporate and cure faster, reducing the situation of surface drying and internal dampness that may occur with traditional heating, and improving drying efficiency.

[0027] like Figure 5 As shown, the processing chamber 1 has a ventilation opening 5 inside; the ventilation opening 5 is connected to an exhaust pipe 51; the other end of the exhaust pipe 51 is fixedly connected to an air suction pump 52. When working, the air suction pump 52 is turned on to generate suction, and the gas inside the ventilation opening 5 is sucked into the air suction pump 52 through the exhaust pipe 51 to achieve the effect of dust removal. The exhaust pipe 51 can remove dust or impurities floating in the air, reduce the accumulation of dust or impurities in the processing chamber 1, keep the inside of the processing chamber 1 clean, reduce the interference of dust or impurities on the uniformity and adhesion of the coating, and enable the coating to achieve a higher quality.

[0028] like Figure 5 As shown, a collection trough 6 is provided at the bottom of the processing chamber 1. The collection trough 6 is located directly below the telescopic nozzle 13. During operation, the paint that is not sprayed onto the inner surface of the tire will accumulate inside the processing chamber 1, condense into lumps or liquid, and be collected through the collection trough 6. This facilitates transportation or reuse and also keeps the inside of the processing chamber 1 clean.

[0029] Working principle: Slide the glass door 17 to the side away from the tire, place the tire to be sprayed vertically in the middle of the rotating rod 16, start the rotating motor 15 to rotate its output end, driving the rotating rod 16 to rotate. The friction generated by the rotation of the rotating rod 16 and its contact with the tire surface causes the tire to rotate. At this time, control the linear motor 21 to slide in the middle of the groove 2, thereby driving the support column 22, so that the sleeve 23 contacts the tire surface and rotates. Then, control the output end of the cylinder 11 to drive the paint storage device 12 to extend into the tire. Then, control the telescopic nozzle 13 to extend into the spray range of the Y-shaped nozzle 14, and open the paint storage device. When device 12 is switched on, the self-healing paint inside the paint storage device 12 is sprayed out from the Y-type nozzle 14 through the telescopic nozzle 13. At the same time, the air pump 3 is switched on, so that the gas is sprayed out along the inner wall of the jet pipe 31 and reaches the inner surface of the tire. The infrared heating tube 41 is turned on, and the light will be diffused in all directions. The diffused light is irradiated onto the sprayed coating through the light focusing plate 42. The suction pump 52 is switched on, generating suction. The gas inside the vent 5 is drawn into the suction pump 52 through the exhaust pipe 51. The paint that is not sprayed onto the inner surface of the tire will accumulate inside the processing chamber 1, condense into lumps or liquid, and be collected through the collection tank 6.
