Description

Technical Field

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

[0002] Tires are primarily made of rubber, which is susceptible to aging due to various factors during long-term use. Ultraviolet (UV) radiation from sunlight is a significant contributor to rubber aging. UV rays can damage the stable structure of rubber molecules, causing cracks to gradually appear on the tire surface. As these cracks develop and spread, the tire's strength decreases dramatically, and its elasticity weakens significantly, reducing both vehicle safety and the overall lifespan of the tire.

[0003] To alleviate this problem, a common practice is to spray anti-aging agents onto the tire surface. These agents form a protective film on the tire surface, blocking ultraviolet rays and thus slowing down the aging process of the rubber. Against this backdrop, various tire coating equipment has emerged on the market, such as a publicly disclosed automatic waste tire coating machine. This equipment consists of several parts. A bracket is installed at each of the left and right ends of the upper surface of the support. The brackets are rotatably connected to a rotating shaft via ball bearings. The left end of the rotating shaft is connected to a drive unit, and the right end is equipped with a tire clamping device to secure the tire. A column is provided on the support. The slider at the top of the column can be fixed with limit screws, and the crossbeam in the middle of the slider can be fixed with set screws. A second stepper motor is installed on one side of the coating frame on the lower surface of the crossbeam. Its output shaft is connected to a ball screw inside the coating frame via a coupling. The sliding end of the ball screw is connected to an atomizing nozzle, and the stepper motor is connected to a controller. The power supply is located on the support and is electrically connected to the controller via a control switch.

[0004] However, existing technologies still have significant drawbacks. When spraying liquid substances onto tires, such equipment can only achieve the spraying operation on the tire tread. To evenly spray the tire shoulder as well, it is often necessary to increase the number of nozzles or spray guns. However, increasing the number of nozzles or spray guns will undoubtedly increase the equipment cost, as well as the difficulty of maintenance and the probability of failure, which hinders the efficient and low-cost development of tire spraying devices. Utility Model Content

[0005] The purpose of this invention is to address the limitation of existing spraying devices, which can only spray liquid substances onto the tire tread. This invention provides a tire spraying device that can complete the entire tire spraying process simply by rotating the fixed part and sliding the spraying part, simplifying the equipment structure, eliminating the need for additional spraying components, and reducing equipment costs.

[0006] To solve the above-mentioned technical problems, an embodiment of this utility model discloses a tire spraying device, the tire spraying device comprising:

[0007] Processing box, including a receiving cavity;

[0008] A fixing part is provided in the receiving cavity, the fixing part is rotatable about a first direction in an axial direction, and the fixing part is used to fix an external tire;

[0009] The spraying part is disposed in the receiving cavity along the second direction. The spraying part is spaced apart from the fixing part and is disposed above the fixing part. The spraying part is used to slide relative to the fixing part within the circumferential range of the tire to spray the outer circumferential surface of the tire. The second direction is perpendicular to the first direction.

[0010] Using the above technical solution, the operation process of the tire spraying device is as follows: First, the operator places the tire on the fixing part and fixes the tire in place. Then, the spraying part slides within the circumferential range of the tire. During this process, the spraying part continuously and evenly sprays liquid onto one arc surface of the tire until the spraying work on that arc surface is completed.

[0011] At this point, the operator drives the fixed part to rotate axially around the first direction, thereby causing the tire to rotate and enter the next arc surface. Subsequently, the spraying part continues to slide within the new circumferential range of the tire, completing another arc-shaped spraying operation. By continuously repeating the above spraying operation, the entire tire can be sprayed.

[0012] The tire spraying device in this technical solution can complete the tire spraying work simply by rotating the fixed part and sliding the spraying part, which simplifies the equipment structure, eliminates the need for additional spraying parts, and reduces equipment costs.

[0013] According to another specific embodiment of this utility model

[0014] The liquid spraying section includes:

[0015] An arc-shaped component extends along the circumferential direction, the receiving cavity includes a top wall, the arc-shaped component is connected to the top wall, the arc-shaped component and the fixing part are spaced apart along the second direction, the arc-shaped component includes an arc-shaped cavity, and the arc-shaped cavity penetrates the arc-shaped component along the second direction;

[0016] A spraying component passes through the arc-shaped cavity and is slidably connected to the arc-shaped component. Along the second direction, the spraying component is spaced apart from the fixed part. The spraying component is used to slide relative to the arc-shaped component to spray the outer peripheral surface of the tire.

[0017] The tire spraying device includes:

[0018] A driving unit is connected to the spraying component and is used to drive the spraying component to slide along the arc-shaped component.

[0019] Using the above technical solution, the shape of the arc-shaped component corresponds to the outer circumference of the tire. Therefore, when the spraying component slides along the arc-shaped component, it can uniformly spray liquid onto the outer circumference of the tire.

[0020] According to another specific embodiment of the present invention, the driving unit includes:

[0021] The first turntable, the receiving cavity includes a first sidewall, the first turntable is disposed on the first sidewall, the first turntable is rotatable about a third direction as an axis, the third direction is perpendicular to the first direction;

[0022] A protrusion is provided on the first turntable and connected to the first turntable;

[0023] A swing arm, the swing arm including a sliding groove that extends through the swing arm, and a protrusion provided in the sliding groove;

[0024] A first connector extends along the third direction, one end of which is connected to the swing arm, and the other end of which is connected to the spray nozzle; wherein...

[0025] When the first turntable rotates, the movement trajectory of the protrusion is within the sliding groove, thereby driving the swing arm to swing, which in turn drives the first connecting member to move the spraying member along the arc-shaped member.

[0026] Using the above technical solution, the operator drives the first turntable to rotate axially around a third direction. The rotation of the first turntable causes the protrusion on the first turntable to perform a circular motion. During the circular motion, the protrusion abuts against the swing arm, and the movement trajectory of the protrusion always remains within the sliding groove. Due to the abutting force of the protrusion, the swing arm drives the first connecting piece connected to it to swing. The swing of the first connecting piece then causes the spray gun to slide along the arc-shaped part, thereby completing the spraying operation on the outer circumference of the tire.

[0027] According to another specific embodiment of the present invention, the arc-shaped component includes:

[0028] The second sidewall faces the first turntable;

[0029] A first through hole, the first through hole penetrating the second sidewall;

[0030] The third sidewall is disposed opposite to the second sidewall, and the liquid spraying component is slidably connected to the first through hole and the third sidewall respectively.

[0031] According to another specific embodiment of the present invention, the driving unit includes a first driving member, which is connected to the first turntable to drive the first turntable to rotate axially about the third direction.

[0032] According to another specific embodiment of the present invention, the fixing part includes:

[0033] A rotating rod extends along the first direction, the receiving cavity includes a fourth sidewall, one end of the rotating rod is rotatably connected to the fourth sidewall, and the rotating rod is axially rotatable about the first direction;

[0034] The second turntable, one side of which is connected to the other end of the rotating rod;

[0035] Multiple support members are disposed on the second turntable and spaced apart along the circumference of the second turntable. The multiple support members are used to support the inner wall of the tire on the outside.

[0036] Using the above technical solution, before the spraying operation, multiple support components support the inner wall of the tire to achieve the technical effect of fixing the tire. While the spray gun completes the spraying operation on one arc surface of the tire, the operator drives the rotating rod to rotate axially around a first direction. The rotating rod drives the second turntable and multiple support components to rotate synchronously, thereby causing the tire to rotate and move into the next arc surface.

[0037] According to another specific embodiment of the present invention, the second turntable is provided with a plurality of first through slots, the plurality of first through slots being arranged at intervals along the circumference of the second turntable, and each first through slot extending radially;

[0038] The fixing part includes:

[0039] A connecting plate is rotatably connected to the other side of the second turntable and is used to rotate relative to the second turntable. The connecting plate is provided with multiple arc-shaped through slots, which are spaced apart around the center of the connecting plate. The multiple arc-shaped through slots, the multiple first through slots, and the multiple support members correspond one-to-one. One end of the support member passes through the corresponding first through slot and the arc-shaped through slot, and one end of the support member is slidably connected to the corresponding arc-shaped through slot.

[0040] A second driving component, connected to the connecting disk, drives the connecting disk to rotate axially about the first direction; wherein...

[0041] The connecting plate is used to rotate relative to the second turntable so that one end of the support member, which is slidably connected to the arcuate through groove, moves radially along the corresponding first through groove.

[0042] Using the above technical solution, when it is necessary to fix the tire, the operator drives the connecting plate to rotate clockwise around the first direction as the axial direction via the second driving component. During this process, the support members are limited by the first through groove on the second turntable. Driven by the rotation of the connecting plate, the support members will gradually move away from each other and slide outward along the direction of the arc-shaped through groove on the connecting plate. When the support members contact the inner wall of the tire, the operator stops rotating the connecting plate, at which point the tire is fixed.

[0043] Similarly, when the tire needs to be removed, the operator drives the connecting disc to rotate counterclockwise around the first direction using the second drive component. The support components remain limited by the first through groove, and the support components move closer to each other, sliding inward along the direction of the arc-shaped through groove. Once the support components are completely out of contact with the inner wall of the tire, the operator can easily remove the tire.

[0044] According to another specific embodiment of the present invention, the support member includes:

[0045] A connecting rod, one end of which passes through the corresponding first through groove and the arc-shaped through groove, and the other end of which is slidably connected to the corresponding arc-shaped through groove;

[0046] An arc-shaped plate is connected to the other end of the connecting rod, and the arc-shaped plate is used to support the inner wall of the tire from the outside.

[0047] According to another specific embodiment of the present invention, the fixing part includes a locking member, which is used to fix the connecting plate relative to the second turntable.

[0048] Using the above technical solution, after the operator fixes the tire, the connecting plate is fixed by the locking component, so that it cannot rotate relative to the second turntable.

[0049] According to another specific embodiment of the present invention, the support member includes a flexible member disposed on the outer surface of the arc-shaped plate, and the flexible member is used to contact the inner wall of the tire in contact with the outside world.

[0050] By adopting the above technical solution, flexible components are provided on the outer surface of the arc-shaped plate to avoid damaging the inner wall of the tire.

[0051] According to another specific embodiment of the present invention, the fixing part includes a third driving member, which is connected to the rotating rod to drive the rotating rod to rotate axially around the first direction. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0073] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0074] refer to Figures 1 to 3This application provides a tire spraying device 100, which includes a processing box 10, a fixing part 20, and a spraying part 30. The processing box 10 is a cuboid and includes a receiving cavity 11. The fixing part 20 is disposed in the receiving cavity 11 and can rotate axially about a first direction X. The fixing part 20 is used to fix an external tire 200.

[0075] The spraying part 30 is disposed in the receiving cavity 11 along the second direction Y. The spraying part 30 is spaced apart from the fixing part 20 and is disposed above the fixing part 20. The spraying part 30 is used to slide relative to the fixing part 20 within the circumferential R range of the outer tire 200 to spray the outer peripheral surface of the outer tire 200. The second direction Y is perpendicular to the first direction X.

[0076] Using the above technical solution, the operation process of the tire spraying device 100 is as follows: First, the operator places the tire 200 on the fixing part 20 and fixes the tire 200 by the fixing part 20. Then, the spraying part 30 slides within the circumferential R range of the tire 200. During this process, the spraying part 30 continuously and evenly sprays liquid onto one arc surface of the tire 200 until the spraying work on the arc surface is completed.

[0077] At this point, the operator drives the fixed part 20 to rotate axially around the first direction X, thereby causing the tire 200 to rotate and enter the next arc surface. Subsequently, the spraying part 30 continues to slide within the new circumferential R range of the tire 200, completing another arc-shaped spraying operation. By continuously repeating the above spraying operation, the complete spraying operation of the tire 200 can be completed.

[0078] The tire spraying device 100 in this technical solution can complete the complete spraying of the tire 200 by simply rotating the fixed part 20 and sliding the spraying part 30, which simplifies the equipment structure, eliminates the need for additional spraying parts, and reduces equipment costs.

[0079] It should be noted that the shape of the processing box 10 is not specifically limited in this embodiment. For example, in other possible implementations, the shape of the processing box 10 can be a cylinder, a triangular prism, etc.

[0080] In some possible implementations, refer to Figures 1 to 4The spraying section 30 includes an arc-shaped member 31 and a spraying member 32, with the arc-shaped member 31 extending circumferentially in the direction R. The receiving cavity 11 includes a top wall 111, and the arc-shaped member 31 is connected to the top wall 111. Along the second direction Y, the arc-shaped member 31 is spaced apart from the fixing part 20. The arc-shaped member 31 includes an arc-shaped cavity 313, which extends through the arc-shaped member 31 along the second direction Y. The spraying member 32 passes through the arc-shaped cavity 313 and is slidably connected to the arc-shaped member 31. Along the second direction Y, the spraying member 32 is spaced apart from the fixing part 20 and is used to slide relative to the arc-shaped member 31 to spray the outer peripheral surface of the tire 200.

[0081] The tire spraying device 100 includes a drive unit 40, which is connected to the spraying component 32. The drive unit 40 is used to drive the spraying component 32 to slide along the arc-shaped component 31.

[0082] Using the above technical solution, the shape of the arc-shaped part 31 corresponds to the outer peripheral surface of the tire 200. Therefore, when the spraying part 32 slides along the arc-shaped part 31, it can uniformly spray liquid onto the outer peripheral surface of the tire 200.

[0083] In some possible implementations, refer to Figures 1 to 4 The drive unit 40 includes a first turntable 41, a protrusion 42, a rocker arm 43, and a first connector 44. The first turntable 41 is circular. The receiving cavity 11 includes a first sidewall 112. The first turntable 41 is disposed on the first sidewall 112. The first turntable 41 is rotatable about a third direction Z as an axis, and the third direction Z is perpendicular to the first direction X.

[0084] The protrusion 42 is cylindrical and is located on and connected to the first turntable 41. The rocker arm 43 includes a sliding groove 431 that extends through the rocker arm 43, and the protrusion 42 is located in the sliding groove 431. The first connecting member 44 is cylindrical and extends along the third direction Z. One end of the first connecting member 44 is connected to the rocker arm 43, and the other end of the first connecting member 44 is connected to the spraying member 32.

[0085] When the first turntable 41 rotates, the movement trajectory of the protrusion 42 is within the sliding groove 431, which drives the swing arm 43 to swing, thereby driving the first connecting member 44 to drive the spraying member 32 to slide along the arc-shaped member 31.

[0086] Using the above technical solution, the operator drives the first turntable 41 to rotate around the Z-axis. The rotation of the first turntable 41 causes the protrusion 42 on the first turntable 41 to perform a circular motion. During the circular motion, the protrusion 42 abuts against the swing arm 43. The movement trajectory of the protrusion 42 always remains within the sliding groove 431. Due to the abutment force of the protrusion 42, the swing arm 43 drives the first connecting member 44 connected to it to swing. The swing of the first connecting member 44 then drives the spraying member 32 to slide along the arc-shaped member 31, thereby completing the spraying operation on the outer circumference of the tire 200.

[0087] It should be noted that the shape of the first turntable 41 is not specifically limited in this embodiment. For example, in other possible implementations, the shape of the first turntable 41 can be a rectangle, a triangle, etc. Similarly, the shape of the first connector 44 is not specifically limited in this embodiment. For example, in other possible implementations, the shape of the first connector 44 can be a cuboid, a triangular prism, etc.

[0088] In some possible implementations, refer to Figures 1 to 4 The arc-shaped component 31 includes a second sidewall 311, a first through hole 312, and a third sidewall 314. The second sidewall 311 faces the first turntable 41. The first through hole 312 is arc-shaped and penetrates through the second sidewall 311. The third sidewall 314 is disposed opposite to the second sidewall 311. The liquid spraying component 32 is slidably connected to the first through hole 312 and the third sidewall 314, respectively.

[0089] In some possible implementations, refer to Figures 1 to 4 The drive unit 40 includes a first drive member (not shown in the figure), which is connected to the first turntable 41 to drive the first turntable 41 to rotate about the third direction Z as the axis.

[0090] It should be noted that the specific structure of the first driving component is not specifically limited in the embodiments of this application. For example, in other possible implementations, the first driving component may be a cylinder, a motor, etc.

[0091] In some possible implementations, refer to Figure 1 , Figure 3 and Figure 5 The fixing part 20 includes a rotating rod 21, a second turntable 22, and three support members 23. The rotating rod 21 is a cylinder that extends along the first direction X. The receiving cavity 11 includes a fourth side wall 113. One end of the rotating rod 21 is rotatably connected to the fourth side wall 113. The rotating rod 21 can rotate axially about the first direction X.

[0092] One side of the second turntable 22 is connected to the other end of the rotating rod 21. Three support members 23 are provided on the second turntable 22 and are spaced apart along the circumferential direction R of the second turntable 22. The three support members 23 are used to support the inner wall of the external tire 200.

[0093] Using the above technical solution, before the spraying operation, multiple support members 23 support the inner wall of the tire 200 to achieve the technical effect of fixing the tire 200. When the spraying component completes the spraying operation on one arc surface of the tire 200, the operator drives the rotating rod 21 to rotate axially around the first direction X. The rotating rod 21 drives the second turntable 22 and multiple support members 23 to rotate synchronously, thereby driving the tire 200 to rotate and allowing the tire 200 to enter the next arc surface.

[0094] It should be noted that the shape of the rotating rod 21 is not specifically limited in this embodiment. For example, in other possible implementations, the shape of the rotating rod 21 can be a cuboid, a triangular prism, etc. The number of support members 23 is not specifically limited in this embodiment. For example, in other possible implementations, the number of support members 23 can be four, five, etc.

[0095] In some possible implementations, refer to Figure 1 , Figure 3 and Figure 5 The second turntable 22 is provided with three first through slots 221. The three first through slots 221 are arranged at intervals along the circumferential direction R of the second turntable 22, and each first through slot 221 extends radially C.

[0096] The fixing part 20 includes a connecting plate 24 and a second driving member 25. The connecting plate 24 is rotatably connected to the other side of the second turntable 22 and is used to rotate relative to the second turntable 22. The connecting plate 24 is provided with three arc-shaped through slots 241, which are spaced apart around the center of the connecting plate 24. The three arc-shaped through slots 241, three first through slots 221, and three support members 23 correspond one-to-one. One end of the support member 23 passes through the corresponding first through slot 221 and arc-shaped through slot 241, and one end of the support member 23 is slidably connected to the corresponding arc-shaped through slot 241.

[0097] The second driving member 25 is connected to the connecting plate 24 to drive the connecting plate 24 to rotate about the first direction X as the axis. The connecting plate 24 is used to rotate relative to the second turntable 22 so that one end of the support member 23, which is slidably connected in the arc-shaped through groove 241, moves radially C along the corresponding first through groove 221.

[0098] Using the above technical solution, when it is necessary to fix the tire 200, the operator drives the connecting plate 24 to rotate clockwise around the first direction X as the axis via the second driving component 25. During this process, the support member 23 is limited by the first through groove 221 on the second turntable 22. Driven by the rotation of the connecting plate 24, each support member 23 will gradually move away from each other and slide outward along the direction of the arc-shaped through groove 241 on the connecting plate 24. When the support member 23 contacts the inner wall of the tire 200, the operator stops rotating the connecting plate 24, at which point the tire 200 is fixed.

[0099] Similarly, when tire 200 needs to be removed, the operator drives the connecting plate 24 to rotate counterclockwise around the first direction X as the axis via the second drive component 25. The support component 23 is still limited by the first through groove 221, and the support components 23 move closer to each other and slide inward along the direction of the arc-shaped through groove 241. Once the support component 23 is completely out of contact with the inner wall of tire 200, the operator can easily remove tire 200.

[0100] It should be noted that the number of first through slots 221 is not specifically limited in this embodiment. For example, in other possible implementations, the number of first through slots 221 may be four, five, etc. Similarly, the number of arc-shaped through slots 241 is not specifically limited in this embodiment. For example, in other possible implementations, the number of arc-shaped through slots 241 may be four, five, etc.

[0101] In some possible implementations, refer to Figure 1 , Figure 3 and Figure 5 The support member 23 includes a connecting rod 231 and an arc-shaped plate 232. One end of the connecting rod 231 passes through the corresponding first through groove 221 and arc-shaped through groove 241, and the connecting rod 231 is slidably connected to the corresponding arc-shaped through groove 241. The arc-shaped plate 232 is connected to the other end of the connecting rod 231 and is used to support the inner wall of the external tire 200.

[0102] In some possible implementations, refer to Figure 1 , Figure 3 and Figure 5 The fixing part 20 includes a locking member 26, which is used to fix the connecting plate 24 relative to the second turntable 22.

[0103] Using the above technical solution, after the operator fixes the tire 200, the connecting plate 24 is fixed by the locking part 26 so that it cannot rotate relative to the second turntable 22.

[0104] In some possible implementations, refer to Figure 1 , Figure 3 and Figure 5The support member 23 includes a flexible member (not shown in the figure), which is located on the outer surface of the arc plate 232 and is used to contact the inner wall of the tire 200 in contact with the outside.

[0105] By adopting the above technical solution, flexible components are provided on the outer surface of the arc plate 232 to avoid damaging the inner wall of the tire 200.

[0106] It should be noted that the specific structure of the flexible component is not specifically limited in the embodiments of this application. For example, in other possible implementations, the flexible component may be a sponge, rubber, etc.

[0107] In some possible implementations, refer to Figure 1 , Figure 3 and Figure 5 The fixing part 20 includes a third driving member (not shown in the figure), which is connected to the rotating rod 21 to drive the rotating rod 21 to rotate axially around the first direction X.

[0108] It should be noted that the specific structure of the third driving component is not specifically limited in the embodiments of this application. For example, in other possible implementations, the third driving component may be a cylinder, a motor, etc.

[0109] Next, combined Figure 1 , Figure 3 and Figure 5 This section details the usage process of the tire spraying device 100.

[0110] Before applying the fluid to the tire, the operator first places the tire 200 on the support member 23, and then drives the connecting plate 24 to rotate clockwise around the first direction X as the axis via the second drive member 25. During this process, the support member 23 is limited by the first through groove 221 on the second turntable 22. Driven by the rotation of the connecting plate 24, the support members 23 gradually move away from each other and slide outward along the direction of the arc-shaped through groove 241 on the connecting plate 24. When the arc plate 232 contacts the inner wall of the tire 200, the operator stops rotating the connecting plate 24, at which point the tire 200 is fixed.

[0111] After the tire 200 is fixed in place, the operator drives the first turntable 41 to rotate around the Z-axis via the first drive component. The rotation of the first turntable 41 causes the protrusion 42 on the first turntable 41 to perform a circular motion. During the circular motion, the protrusion 42 abuts against the swing arm 43, and the movement trajectory of the protrusion 42 remains within the sliding groove 431. Due to the abutment force of the protrusion 42, the swing arm 43 drives the first connecting member 44 connected to it to swing. The swing of the first connecting member 44 then causes the spraying component 32 to slide along the arc-shaped component 31, thereby completing the spraying operation on an arc-shaped surface of the outer circumference of the tire 200.

[0112] Subsequently, the operator drives the rotating rod 21 through the third driving component to drive the second turntable 22 and the tire 200 to rotate around the first direction X as the axis, so that the tire 200 enters the next arc surface, and the spraying component 32 continues to slide within the new circumferential R range of the tire 200 to complete another arc-shaped spraying operation. By continuously repeating the above spraying operation, the complete spraying operation of the tire 200 can be completed.

[0113] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
