Description

Technical Field

[0001] This utility model relates to the field of tire spraying technology, and in particular to a tire spraying device for rubber tire production. Background Technology

[0002] Tire spraying equipment is a key piece of equipment in rubber tire production. It can uniformly spray various coatings such as protective and decorative coatings on the surface or inside of tires to improve tire performance and appearance, ensure product quality, and meet production efficiency and environmental protection requirements. It is widely used in the tire manufacturing industry.

[0003] The tire spraying device for rubber tire production is a professional equipment used in the tire manufacturing process to spray paint onto the tire surface. The tire is secured by a fixing device, and the paint supply device delivers the paint to the spray gun. Under power drive, the spray gun atomizes the paint evenly and sprays it onto the tire surface along a preset trajectory.

[0004] In existing technologies, some tire spraying devices suffer from numerous drawbacks in the tire fixing process due to the traditional tire spraying method. They often use simple clamps or manual support to fix the tire, which not only consumes a lot of manpower but also has a very poor fixing effect. This leads to shaking and displacement of the tire during the spraying process, resulting in uneven spraying, which seriously affects the consistency of the tire's appearance and significantly increases the defect rate. Therefore, a tire spraying device for rubber tire production is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a tire spraying device for rubber tire production, which aims to improve the problem of uneven spraying caused by shaking and displacement of the tire during the spraying process in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tire spraying device for rubber tire production includes a base plate, a plurality of support columns fixedly connected to the top of the base plate, a connecting ring fixedly connected to the top of the plurality of support columns, a worktable fixedly connected to the inner wall of the connecting ring, a cylinder fixedly connected to the bottom of the worktable, a connecting column fixedly connected to the driving end of the cylinder, a plurality of rotating plates rotatably connected to the outer ring of the connecting column, a fixed ring rotatably connected to the bottom of one of the rotating plates, a slider fixedly connected to the bottom of the fixed ring, a plurality of fixed blocks fixedly connected to the top of the worktable, a groove formed inside one of the fixed blocks, a spring fixedly connected to the left side of the inner wall of the groove, and a collection component for recovering and collecting sprayed liquid fixedly connected to the top of the connecting ring.

[0008] As a further description of the above technical solution:

[0009] The collection component includes a guide block one, a guide block two is fixedly connected to the bottom of the connecting ring, and a collection box is provided at the bottom of the base plate;

[0010] As a further description of the above technical solution:

[0011] A support plate is fixedly connected to the top left side of the base plate, a connecting plate is fixedly connected to the top right side of the support plate, a motor is fixedly connected to the top of the connecting plate, and a threaded rod is fixedly connected to the drive end of the motor.

[0012] As a further description of the above technical solution:

[0013] The threaded rod is externally threaded to a connecting plate, the top of the connecting plate is fixedly connected to a liquid storage box, and the bottom of the liquid storage box is fixedly connected to a spray box.

[0014] As a further description of the above technical solution:

[0015] Two connecting rods are fixedly connected to the bottom of the connecting plate, and a distance sensor is fixedly connected to the bottom of the two connecting rods on their adjacent sides.

[0016] As a further description of the above technical solution:

[0017] The right side of the spring is fixedly connected to the left side of the slider. When the tire is placed, the cylinder drives the connecting column to move, thereby driving the rotating plate to pull back the fixed ring.

[0018] As a further description of the above technical solution:

[0019] When the fixed ring retracts, it slides inside the groove via the slider. After placement, the cylinder drives the connecting column to move the rotating plate, which in turn moves the fixed ring. At the same time, the elasticity of the spring pushes the slider to return the fixed ring to its original position and press it tightly against the inside of the tire.

[0020] As a further description of the above technical solution:

[0021] During spraying, the spray box is collected by the first guide block and then flows through the connecting ring and the empty groove of the worktable to the second guide block and then to the collection box for collection. The bottom of the first guide block is fixedly connected to the top of the connecting ring.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the connecting column is retracted by the cylinder, which drives the rotating plate to push the fixed ring into the tire. At the same time, with the help of the elasticity of the spring on the left side of the inner wall of the slide groove, the slider is pushed to drive the fixed ring back to its original position, so that the four fixed rings are tightly pressed against the inner wall of the tire. This effectively prevents the tire from shaking or shifting during the spraying operation, ensures the uniformity of the spraying, greatly improves the appearance quality of the tire, can quickly adapt to tires of different sizes, does not require cumbersome adjustments, and significantly improves production efficiency.

[0024] 2. In this utility model, the liquid that falls during the spraying process is first collected by guide block one, and then flows along the groove between the connecting ring and the worktable to guide block two at the bottom of the connecting ring. Guide block two accurately guides the liquid to the collection box at the bottom of the base plate, thereby avoiding the liquid from scattering everywhere and polluting the work area, maintaining a clean production environment, reducing cleaning costs, reducing paint waste, and saving production costs.

The worktable 4 is fixedly connected to the inner wall of the connecting ring 3. The worktable 4 is used for tire spraying. A cylinder 5 is fixedly connected to the bottom of the worktable 4, serving as the power source for the clamping assembly. A protective box is provided outside the cylinder 5 to protect it from contamination when collecting spraying liquid. A connecting column 6 is fixedly connected to the drive end of the cylinder 5, and the connecting column 6 moves by receiving force from the cylinder 5.

[0033] Multiple rotating plates 7 are rotatably connected to the outer ring of the connecting column 6. The rotating plates 7 move under the force from the connecting column 6. A fixing ring 8 is rotatably connected to the bottom of one of the rotating plates 7. The outside of the fixing ring 8 contacts the inner wall of the tire for fixation. A slider 9 is fixedly connected to the bottom of the fixing ring 8. The fixing ring 8 can slide smoothly through the slider 9. Multiple fixing blocks 10 are fixedly connected to the top of the worktable 4. The fixing blocks 10 provide space for the opening of the internal slide groove 11. The slide groove 11 is opened inside one of the fixing blocks 10. The slide groove 11 is fixedly supported by a spring 12. The inner wall of the slide groove 11 is fixedly connected to the left side of the spring 12. The spring 12 has an elastic function. A collection component for recycling and collecting sprayed liquid is fixedly connected to the top of the connecting ring 3.

[0034] Reference Figure 2 and Figure 3 The collection component includes a guide block 13, which is used to collect the liquid that falls during spraying. A guide block 2 14 is fixedly connected to the bottom of the connecting ring 3, and is further transported to subsequent components through the guide block 2 14. A collection box 15 is provided at the bottom of the base plate 1, which is used to recycle the sprayed liquid.

[0035] Reference Figures 1 to 3A support plate 16 is fixedly connected to the top left of the base plate 1. The support plate 16 provides fixation and support for the connecting plate 17. A connecting plate 17 is fixedly connected to the top right of the support plate 16. The connecting plate 17 provides fixation and support for the motor 18. A motor 18 is fixedly connected to the top of the connecting plate 17. The motor 18 is the power source for adjusting the height. A threaded rod 19 is fixedly connected to the drive end of the motor 18. The threaded rod 19 receives the force from the motor 18 and rotates. A connecting plate 20 is connected to the external thread of the threaded rod 19. The rotation of the threaded rod 19 drives the connecting plate 20 to rotate. A liquid storage box 21 is fixedly connected to the top of the connecting plate 20. The liquid storage box 21 is used to store the spraying liquid. A spraying box 22 is fixedly connected to the bottom of the liquid storage box 21. The spraying box 22 is used for spraying the outside of the tire.

[0036] Two connecting rods 23 are fixedly connected to the bottom of the connecting plate 20. The connecting rods 23 provide fixation and support for the distance sensor 24. The distance sensor 24 is fixedly connected to the bottom of the two connecting rods 23 on the adjacent side. The distance sensor 24 is used to detect the position of the spray box 22. When the spray box 22 moves to the bottom, the motor 18 drives the threaded rod 19 to drive the connecting plate 17 to rise. The right side of the spring 12 is fixedly connected to the left side of the slider 9. The spring 12 provides elastic support for the slider 9. When the tire is placed, the cylinder 5 drives the connecting column 6 to move, which in turn drives the rotating plate 7 to pull back the fixing ring 8. When the tire needs to be placed, the cylinder 5 drives the connecting column 6 to move, which in turn drives the rotating plate 7 to move. The rotating plate 7 drives the fixing ring 8 to retract. When the fixing ring 8 retracts, the slider 9 slides inside the slide groove 11. When the fixing ring 8 retracts, it drives the bottom slider 9 to slide inside the slide groove 11, so that the fixing ring 8 can slide more smoothly.

[0037] After placement, cylinder 5 drives connecting column 6 to move rotating plate 7, which in turn moves fixing ring 8. Once the tire is in place, cylinder 5 retracts connecting column 6, which in turn moves rotating plate 7, pushing fixing ring 8. Simultaneously, spring 12's elasticity pushes slider 9 to return fixing ring 8 to its original position, tightening it against the inside of the tire. Spring 12's elasticity also pushes slider 9 at the bottom of fixing ring 8 to reset. The four fixing rings 8 secure the inside of the tire. During spraying, the spray box 22... The spray liquid is collected by guide block 13 and flows through the groove between connecting ring 3 and workbench 4 to guide block 2 14 and then to collection box 15. When the tire is sprayed, the spray liquid that falls off is collected by guide block 13 and then flows through the groove between connecting ring 3 and workbench 4 to guide block 2 14. Guide block 2 14 then transports the liquid to the inside of collection box 15, completing the collection and recycling of the spray liquid. The bottom of guide block 13 is fixedly connected to the top of connecting ring 3, which provides fixation and support for guide block 13.

[0038] Working principle: When placing a tire, the cylinder 5 first drives the connecting column 6 to move. The connecting column 6 drives the four rotating plates 7 distributed in a ring around it to move synchronously, thereby pulling back the fixing ring 8 to move. At this time, the slider 9 at the bottom of the fixing ring 8 slides in the groove 11 with the fixing ring 8, which facilitates the placement of the tire. After the tire is placed, the cylinder 5 retracts the connecting column 6, which drives the rotating plates 7 to push the fixing ring 8 into the tire. At the same time, with the help of the elasticity of the spring 12 on the left side of the inner wall of the groove 11, the slider 9 is pushed to move the fixing ring 8 back to its original position, so that the four fixing rings 8 are tightly pressed against the inner wall of the tire, realizing stable clamping of tires of different sizes and ensuring that the tire will not shake or shift during the subsequent spraying process.

[0039] When spraying paint on the exterior of the tire, if it is necessary to collect and recycle the spraying liquid, the liquid that falls during the spraying process is first collected by guide block 13, and then flows along the empty groove of connecting ring 3 and worktable 4 to guide block 2 14 at the bottom of connecting ring 3. Guide block 2 14 accurately guides the liquid to the collection box 15 at the bottom of base plate 1, completing the recycling of spraying liquid, avoiding the liquid from flowing randomly and causing pollution, while saving paint resources and ensuring the cleanliness and orderliness of the work area.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
