Technical Field

[0001] The invention relates to the technical field of tire production, and in particular to tire spraying equipment for rubber tire production. Background Art

[0002] Tire self-sealing adhesive is a kind of colloid widely used on the inside of tires. When a sharp object punctures the tire, the adhesive can seal the puncture while the sharp object is pulled out, effectively ensuring driving safety.

[0015] Compared with the existing technology, the present invention has the following beneficial effects: 1. In the process of limiting the left and right positions of the tire, the two gear shafts respectively make the transmission shaft 1 rotate clockwise through the two pulley assemblies 1, the rotation of the transmission shaft 1 drives the four cone wheels 2 to rotate, the rotation of the four cone wheels 2 drives the four cone wheels 1 to rotate, the movement of the four cone wheels 1 drives the four gears 5 to rotate, the four gears 5 mesh with the double-sided rack U-shaped plate to move the double-sided rack U-shaped plate upward, the movement of the double-sided rack U-shaped plate pulls the circular piston to move upward, because the circular piston and the cylindrical box are in a sealed state, and then the liquid inside the small rubber box is sucked through the tube, so that the narrower the tire width, the more the cylindrical box absorbs, and the less the small rubber box has left, so that the remaining glue in the small rubber box is adapted to the width of the tire; 2. In the process of limiting the upper and lower positions of the tire, the transmission shaft 2 located at the lower part of the vertical displacement mechanism drives the transmission shaft 3 to rotate clockwise through the two pulley assemblies 3. The rotation of the transmission shaft 3 drives the two gears 3 to rotate clockwise. The two gears 3 mesh with the rack plate to move, so that the rack plate moves away from the square box. The movement of the rack plate pulls the piston plate 1 to move. Since a closed space is formed between the piston plate 1 and the square box, the liquid inside the small rubber box is sucked through the tube, so that the remaining glue in the small rubber box is adapted to the height of the tire; 3. The cylindrical box and the square box respectively suck the glue in the small glue box, and the glue in the small glue box will be reduced. Since a closed space is formed between the piston plate 2 and the small glue box, the piston plate 2 will drop as the glue in the small glue box drops, so that the piston plate 2 scrapes the glue remaining on the inner wall of the small glue box. The downward movement of the piston plate 2 drives the rack 3 to move downward, and the movement of the rack 3 drives the gear 2 on the small glue box to rotate, thereby reducing the flow in the glue spraying hose, making the flow of the glue spraying hose adapt to the size of the tire, and making the glue sprayed on the inner wall of the tire more uniform; 4. When the spraying is finished, the motor 3 is turned off, and the driving motor 1 rotates forward, driving the four clamping plates to move away from each other, and at the same time, the double-sided rack U-shaped plate moves downward. The movement of the double-sided rack U-shaped plate pushes the glue liquid extracted from the inside of the cylindrical box into the inside of the small glue box, and at the same time drives the rack 4 to move downward. The rack 4 meshes with the gear 4, and the rotation of the gear 4 drives the rotating shaft 2 and the circular plate to rotate, and then drives the two scrapers to scrape the glue liquid on the inner walls of the two sealing plates respectively, so that the glue liquid flows into the bottom of the sealing plate and is discharged through the hole. The hole can be connected to a collection box, so that the glue liquid can be recovered and reused; To summarize, the present invention limits the tire up and down and left and right through the vertical displacement mechanism and the lateral displacement mechanism, and reduces the glue in the small glue box as it moves. The reduction of the glue in the small glue box will drive the regulating mechanism to adjust the flow of the glue spray hose through the control valve, so that the flow of the glue spray hose and the amount of liquid in the small glue box are matched with the volume of the tire, avoiding excessive or insufficient spraying of glue, causing waste or affecting the quality of the tire, and during the spraying process, the two sealing plates and the tire form a closed space, which effectively prevents the glue from flying around, and at the same time, after the spraying is completed, the movement of the lateral displacement mechanism drives the cleaning mechanism to scrape the glue on the sealing plate, so that the glue can be recycled and reused.

The support plate three 22 is located in the middle position of the tire frame 3, and the bottom of the support plate three 22 is fixedly connected with four telescopic rods 24, two of which are fixedly connected to the inner wall of the tire frame 3, and the other two telescopic rods 24 are fixedly connected to the top of the working plate 2.

[0032] In this embodiment, the tire is placed on the support plate three 22, and the support plate three 22 moves downward due to gravity, driving the two movable plates 21 close to the side of the support plate three 22 to move downward, thereby centering the tire.

[0033] Among them, the interiors of the two seat clamps 20 are both rotatably connected to multiple rollers 33, and the multiple rollers 33 are kept rotating in the same direction by a pulley assembly four 35. The top of one of the racks 18 is fixedly connected to a motor three 36, and the output shaft of the motor three 36 is fixedly connected to one of the rollers 33.

[0034] In this embodiment, after the limiting is completed, that is, the suction is completed, the external power supply of the motor three 36 is turned on, and the multiple rollers 33 are driven to rotate through the pulley assembly four 35, and then the tire is driven to rotate. The clamping plates 16 and the sealing plates 41 on both sides can limit the tire and increase the stability of rotation. Because the tire is placed vertically, the glue can be sprayed more evenly on the inner wall of the tire.

[0035] The specific working principle and use method of the present invention are explained in detail below: When using, Figure 4 As shown, the external power supply of the motor 23 is turned on, and the lower part of the vertical displacement mechanism 101 is seen. The motor 23 rotates forward, driving the gear 17 to rotate counterclockwise. The rotation of the gear 17 drives the rack 18 to move downward, so that the seat clamp 20 moves downward, and then under the action of the transmission shaft 213 and the pulley assembly 212, the seat clamp 20 located on the inner wall of the upper side of the tire frame 3 is driven to move upward, so that the two seat clamps 20 are separated from each other and reach the farthest point, and the motor 23 is turned off, and then, as shown in FIG. Figure 1 As shown, see the left part of the lateral displacement mechanism 202, connect the external power supply of motor 15, motor 15 rotates forward, driving the gear shaft 27 to rotate counterclockwise, and the rotation of the gear shaft 27 drives the two racks 25 away from the gear shaft 27, thereby driving the two splints 16 away from each other, and under the action of the pulley assembly 11 and the transmission shaft 10, the two splints 16 located on the left inner wall of the tire frame 3 are driven away from each other, and when they reach the farthest point, the motor 15 is turned off; the pump inside the glue storage box 1 is turned on, so that the glue storage box 1 injects glue into the small glue box 40, so that the inside of the small glue box 40 is filled with glue.

[0036] Put the tire on the support plate three 22, and the support plate three 22 moves downward under the gravity, driving the two movable plates 21 close to the side of the support plate three 22 to move downward, thereby playing a centering role on the tire, making the motor one 15 reverse, driving the two gear shafts 27 to rotate clockwise, and the two gear shafts 27 are respectively meshed with the four racks two 25 to move, driving the two clamps 16 to approach, so that the four clamps 16 are in contact with the tire and are in the left and right centering position of the tire frame 3, shutting down the motor one 15, limiting the left and right positions of the tire, and reversing the motor two 23, driving the four gears one 17 to rotate clockwise, and the four gears one 17 are respectively meshed with the four racks one 18 to move, driving the seat clamp 20 to move downward, so that the two seat clamps 20 are in contact with the tire and are in the upper and lower centering position of the tire frame 3, shutting down the motor two 23, and limiting the upper and lower positions of the tire.

[0037] In the process of limiting the left and right positions of the tire, the two gear shafts 27 respectively make the transmission shaft 10 rotate clockwise through the two pulley assemblies 11, and the rotation of the transmission shaft 10 drives the four cone wheels 2 52 to rotate, and the rotation of the four cone wheels 2 52 drives the four cone wheels 1 51 to rotate, and the movement of the four cone wheels 1 51 drives the four gears 5 19 to rotate, and the four gears 5 19 mesh with the double-sided rack U-shaped plate 44 to move the double-sided rack U-shaped plate 44 upward, and the movement of the double-sided rack U-shaped plate 44 pulls the circular piston 45 upward. Since the circular piston 45 and the cylindrical box 5 are in a sealed state, the liquid inside the small rubber box 40 is sucked through the tube to achieve the purpose of achieving the narrower the tire width, the more the cylindrical box 5 absorbs, and the less the remaining in the small rubber box 40, so that the remaining glue in the small rubber box 40 is adapted to the width of the tire.

[0038] During the process of limiting the upper and lower positions of the tire, the transmission shaft 2 13 located at the lower part of the vertical displacement mechanism 101 drives the transmission shaft 3 37 to rotate clockwise through the two pulley assemblies 3 30. The rotation of the transmission shaft 37 drives the two gears 3 39 to rotate clockwise. The two gears 39 mesh with the rack plate 31, so that the rack plate 31 moves away from the square box 29. The movement of the rack plate 31 pulls the piston plate 1 32 to move. Since a closed space is formed between the piston plate 1 32 and the square box 29, the liquid inside the small rubber box 40 is sucked through the tube, so that the remaining rubber liquid in the small rubber box 40 is adapted to the height of the tire.

[0039] The cylindrical box 5 and the square box 29 respectively suck the glue in the small glue box 40, and the glue in the small glue box 40 will be reduced. Since a closed space is formed between the piston plate 2 43 and the small glue box 40, the piston plate 2 43 will descend as the glue in the small glue box 40 descends, so that the piston plate 2 43 scrapes the glue remaining on the inner wall of the small glue box 40. At the same time, the downward movement of the piston plate 2 43 drives the rack 3 38 to move downward. The movement of the rack 3 38 drives the gear 2 34 on the small glue box 40 to rotate, thereby reducing the flow in the glue spraying pipe 42, so that the flow of the glue spraying pipe 42 and the liquid amount of the small glue box 40 are adapted to the size of the tire, so that the glue sprayed on the inner wall of the tire is more uniform.

[0040] After the limiting is completed, that is, the suction is completed, the pump connected to the glue spraying hose 42 is opened to extract the liquid in the small glue box 40, and then the inside of the tire is sprayed. During the spraying process, the two sealing plates 41 and the inside of the tire form a closed space, which effectively prevents the glue from being sprayed onto the transmission equipment and affecting the work. At the same time, the external power supply of the motor three 36 is turned on, and the multiple rollers 33 are driven to rotate through the pulley assembly four 35, thereby driving the tire to rotate. The clamping plates 16 and the sealing plates 41 on both sides can limit the tire and increase the stability of rotation. Because the tire is placed vertically, the glue can be sprayed more evenly on the inner wall of the tire.

[0041] When the spraying is finished, the motor 36 is turned off, the driving motor 15 rotates forward, and the four clamping plates 16 are driven to move away from each other, and the double-sided rack U-shaped plate 44 is moved downward. The movement of the double-sided rack U-shaped plate 44 causes the glue liquid extracted from the cylindrical box 5 to be pushed into the small glue box 40, and the rack 49 is driven to move downward. The rack 49 meshes with the gear 48, and the rotation of the gear 48 drives the rotating shaft 2 46 and the circular plate 50 to rotate, thereby driving the two scrapers 28 to respectively scrape the inner walls of the two sealing plates 41. The glue on the tire is scraped off so that the glue flows into the bottom of the sealing plate 41 and is discharged through the hole. The hole can be connected to a collection box so that the glue can be recovered and reused, and the motor 15 is turned off; the drive motor 23 rotates forward, driving the two seat clamps 20 to move away from each other, and the tire is taken out. At the same time, the gear 39 is driven to engage with the rack plate 31 through the action of the pulley assembly 3 30 and the transmission shaft 3 37, so that the piston plate 1 32 pushes the glue sucked in the square box 29 back into the small glue box 40.

[0042] When spraying the next tire, the pump in the glue storage box 1 is turned on to fill the interior of the small glue box 40 with glue, and then the above operation is repeated.

[0043] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
