Description

Technical Field

[0001] This utility model belongs to the field of rubber tire technology, specifically relating to a spraying device for tire production. Background Technology

[0002] Car tires are one of the most important components of a vehicle. They come into direct contact with the road surface and, together with the vehicle's suspension, mitigate the impact of driving, ensuring good ride comfort and smooth driving. In the tire manufacturing process, spraying is a crucial step. By spraying a protective liquid, the tire surface is coated, thereby improving the tire's performance and durability. Spraying requires a spraying device. Existing spraying devices require fixing the tire before spraying, which is cumbersome, affects processing efficiency, and cannot guarantee consistent coating quality. Furthermore, existing spraying devices cannot absorb the protective liquid that diffuses into the air after spraying, causing it to spread everywhere, which not only affects the health of workers but also pollutes the environment.

[0003] A Chinese patent with publication number CN222174535U discloses an environmentally friendly tire processing and spraying device, including a spraying box. Fixed plates are fixedly connected to the bottom left and right sides of the inner wall of the spraying box. A drive shaft is rotatably connected to the upper end of each fixed plate. First rollers are fixedly connected to the outside of each drive shaft. The rear end of each drive shaft passes through the rear end of the spraying box and is fixedly connected to pulleys. The pulleys are connected to each other by a belt. A support plate is fixedly connected to the rear side of the spraying box. A motor is fixedly connected to the upper surface of the support plate. The drive shaft of the motor is fixedly connected to the top of the rear end of the right-side drive shaft. A connecting plate is fixedly connected to the rear side of the inner wall of the spraying box. A first electric push rod is fixedly connected to the lower front end of the connecting plate. A second roller is rotatably connected to the lower end of the first electric push rod.

[0004] The aforementioned existing technologies can absorb spilled liquids during the spraying process, protecting the environment and the health of workers. However, they cannot solve the problem of dust on rubber tires before spraying, which can lead to uneven spraying and make the spraying unsuitable for different sizes of rubber tires.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0023] like Figure 1-4As shown, this utility model discloses a tire production spraying device, including a base 1. The top left side of the base 1 is connected to a placement chamber 2 for placing rubber tires. The top right side of the base 1 is provided with a movable plate 3. The top front and rear sides of the top of the base 1 are symmetrically connected with first slide rails 4, which are slidably connected to the movable plate 3. The movable plate 3 can slide on the first slide rails 4. The side of the movable plate 3 away from the placement chamber 2 is connected to a support plate 5, which is a rectangular platform. The top of the support plate 5 is provided with a paint tank 6 and an air chamber 7 side by side. The movable plate 3 is embedded near the top and at the center with a first pipe 8. The end of the first pipe 8 away from the movable plate 3 is connected to an adjusting nozzle 9, and the other end of the first pipe 8 is connected to the paint tank 6 and the air chamber 7 respectively.

[0024] The adjustable nozzle 9 has multiple spray holes 901 on its sidewall, arranged in two rows. A second slide rail 902 is connected to the inner side of the sidewall with the multiple spray holes 901. A movable baffle 903 is slidably connected to the second slide rail 902 and can move on the second slide rail 902. A knob 904 is provided at the top of the adjustable nozzle 9, and a connecting rod 905 is connected to the bottom of the knob 904. The other end of the connecting rod 905 is located inside the adjustable nozzle 9, and a gear 906 is sleeved on the outer side of the other end of the connecting rod 905. The gear 906 meshes with the movable baffle 903. Turning the knob 904 will drive the gear 906 to rotate. Since the gear 906 meshes with the movable baffle 903, it will drive the movable baffle 903 to move, blocking or expanding the spray holes 901, thereby adapting to the spraying of rubber tires of different sizes.

[0025] The placement chamber 2 is connected to a first fixed bracket 201, which is a concave groove. Two transmission rollers 202 are connected side by side inside the first fixed bracket 201. A first drive motor 203 is connected to the top of the placement chamber 2. The output end of the first drive motor 203 passes through the placement chamber 2 and is connected to a telescopic rod 204. The other end of the telescopic rod 204 is fixed to a second fixed bracket 205. Two transmission rollers 202 are connected side by side inside the second fixed bracket 205. The first drive motor 203 can control the up and down movement of the second fixed bracket 205 to place the rubber tires onto the first fixed bracket 201 and move the second fixed bracket 205, thereby fixing rubber tires of different sizes.

[0026] A circular groove 206 is provided on the inner side wall of the placement chamber 2. A fan 207 is installed in the circular groove 206. A suction device 208 is connected to the circular groove 206 on the outer side wall of the placement chamber 2 through a pipe. The suction device 208 generates negative pressure, which is driven by the fan 207 to collect dust on the surface of the rubber tire or paint floating in the air.

[0027] Each of the four drive rollers 202 has one end passing through the side wall of the placement chamber 2 and fitted with a pulley 209. The pulleys 209 are connected to each other by a belt 210. One of the drive rollers 202 is connected to a second drive motor 211. When the drive roller 202 connected to the second drive motor 211 rotates, the other three drive rollers 202 will also rotate due to the action of the belt, thereby driving the rotation of the rubber tire.

[0028] The bottom end of the movable plate 3 is slidably connected to a lead screw 301, and the end of the lead screw 301 away from the placement chamber 2 is connected to a servo motor.

[0029] A connecting valve 10 is provided at the connection point between the first pipe 8 and the paint box 6 and the air chamber 7. The connecting valve 10 can ensure that the passage to the paint box 6 is blocked when the air chamber 7 is in operation, so as to prevent pollution.

[0030] Working principle: When the device is working, the rubber tire is placed on the first fixed bracket 201 in the placement chamber 2. The first drive motor 203 is controlled to adjust the second fixed bracket 205 to a suitable position to fix the rubber tire. The rubber tire is on the transmission roller 202. According to the rubber tire size adjustment knob 904, the number of spray holes 901 to spray is selected. The servo motor is driven to move the moving plate 3 and place the adjusting nozzle 9 inside the rubber tire. The second drive motor 211 is driven to rotate the transmission roller 202 and drive the rubber tire to rotate. The connecting valve 10 connecting to the paint tank 6 is closed. The air chamber 7 starts to operate first. The adjusting nozzle 9 sprays high-pressure gas to blow away the dust inside the rubber tire. The suction device 208 collects the dust through the fan 207. Then the connecting valve 10 connecting to the paint tank 6 is opened and the connecting valve 10 connecting to the ventilation chamber 7 is closed to spray the rubber tire. At this time, the suction device 208 collects the scattered paint through the fan 207.
