Technical Field
[0001] This utility model relates to the field of tire manufacturing equipment technology, specifically to a deburring device for manufacturing small and medium-sized tires. Background Technology
[0002] In the tire manufacturing process, newly manufactured tires often have a large number of burrs. These burrs not only affect the tire's appearance but may also affect its performance. Therefore, burr removal is a crucial step in tire production. Currently, due to the small-batch, multi-batch nature of small and medium-sized tire manufacturing, the market mainly relies on manual burr removal. This method involves manually operating handheld equipment. The tire is placed on a rotating table, and a special blade is pressed onto the tire. The rotating table then removes the burrs. To remove burrs from both the tread and shoulder, both sides need to be removed in two stages. This not only increases the labor intensity for workers but is also inefficient, makes it difficult to guarantee the quality of burr removal, and poses safety hazards. Manual operation is subject to many uncertainties, and prolonged work can lead to hand fatigue and deformities, affecting the uniformity of burr removal and sometimes even resulting in defective tires. Furthermore, the rubber waste generated during burr removal may pose a threat to workers' health. Many companies in my country's tire industry are small and medium-sized enterprises, and due to cost constraints, their levels of automation and integration are relatively low.
[0003] Current market solutions for deburring small and medium-sized tires suffer from problems such as inability to remove burrs omnidirectionally, uneven removal, and low efficiency. Therefore, it is necessary to develop a device capable of omnidirectional, automated deburring for small and medium-sized tires. This device should ensure operational safety, a reasonable structure, and high reliability while minimizing costs to maximize economic benefits. Utility Model Content

[0047] The pushing and positioning device includes a lateral pushing component and a longitudinal pushing component. The lateral pushing component pushes the tire 9 from the first conveying device 2 to the top of the main frame 1. The longitudinal pushing component cooperates with the lateral pushing component to position the tire 9 located at the top of the main frame 1. Then, the longitudinal pushing component pushes the tire 9 from the top of the main frame 1 to the second conveying device 3.
[0048] The transverse pushing assembly includes a first pushing frame 61 and a first electric cylinder 62, and the longitudinal pushing assembly includes a second pushing frame 63 and a second electric cylinder 64. Both the first pushing frame 61 and the second pushing frame 63 are L-shaped structures formed by connecting a transverse plate and a longitudinal plate. The right end of the transverse plate of the first pushing frame 61 is fixedly welded to the front end of its longitudinal plate, and the seat end of the transverse plate of the second pushing frame 63 is fixedly welded to the rear end of its longitudinal plate.
[0049] The first pusher 61 is horizontally arranged above the conveyor belt 24 of the first conveying device 2. The first electric cylinder 62 is fixed to the right side of the conveyor frame 21 of the first conveying device 2, and its execution end is fixedly connected to the longitudinal plate of the first pusher 61.

[0050] The second pusher 63 is horizontally arranged above the main frame 1. The second electric cylinder 64 is located behind the second pusher 63 and fixed on the main frame 1. Its actuator is fixedly connected to the cross plate of the second pusher 63. The second electric cylinder 64 drives the second pusher 63 to move back and forth.
[0051] The rotary worktable 4 is a frustum-shaped structure with a cavity. The telescopic support device 7 includes a second drive mechanism and three support heads 71. All support heads 71 are evenly arranged in a ring above the rotary worktable 4, and each support head 71 is slidably engaged with the rotary worktable 4 through a linear guide assembly. Specifically, the linear guide assembly includes a guide rail seat 72 and a sliding plate 73. All guide rail seats 72 are evenly distributed on the circumference centered on the axis of the rotary worktable 4 and are fixed to the upper surface of the rotary worktable 4. The sliding plate 73 is slidably disposed on the inner side of the guide rail seat 72 and moves linearly along the normal direction of the rotary worktable 4 relative to the guide rail seat 72.
[0052] The support head 71 is fixed to the end of the sliding plate 73 away from the center of the rotary table 4. Its outer wall is an arc-shaped surface that matches the internal cavity of the tire 9. A transmission rod 74 is provided above the end of the sliding plate 73 near the center of the rotary table 4. The transmission rod 74 is arranged vertically and its lower end is fixedly connected to the upper surface of the sliding plate 73.
[0053] The second drive mechanism is located at the center of the rotary table 4, driving all the support heads 71 to retract or expand synchronously relative to the rotary table 4. In the working state, the second drive mechanism drives all the sliding plates 73 to move synchronously through the transmission rod 74.
[0054] Specifically, the second drive mechanism includes a rotary disk 75, a gear 76, a rack 77, and a third electric cylinder 78. The rotary disk 75 is located above the rotary worktable 4, and its bottom is coaxially rotatably connected to the rotary worktable 4 via a vertical shaft 79. The lower end of the vertical shaft 79 passes into the interior of the rotary worktable 4 and is rotatably connected to the rotary worktable 4 via a thrust bearing installed at the bottom of the cavity. The gear 76 is located inside the rotary worktable 4, and the gear 76 is sleeved on the outside of the vertical shaft 79 and connected to the vertical shaft 79 via a flat key. The gear 76 drives the vertical shaft 79 to rotate synchronously with it.
[0055] The rotating disk 75 has an equal number of involute grooves 751 as the transmission rods 74. All the involute grooves 751 are evenly distributed in a ring on the circumference of the rotating disk 75, and correspond one-to-one with the positions of the transmission rods 74. The upper part of each transmission rod 74 is located inside the corresponding involute groove 751 and slides in engagement with the rotating disk 75. The rack 77 is located on one side of the gear 76 and slides linearly in engagement with the inner wall of the rotating worktable 4. The third electric cylinder 78 is fixed inside the cavity of the rotating worktable 4, and its actuating end is fixedly connected to one end of the rack 77. The rotating disk 75 is driven to rotate horizontally relative to the rotating worktable 4 through the rack 77 and the gear 76.
[0056] Before the tire 9 reaches the top of the main frame 1 from the first conveying device 2, the rotating disk 75 is located below the top plate 11 of the main frame 1, and all three support heads 71 are retracted and located inside the outer contour of the rotating worktable 4. The first pusher 61 pushes the burr-covered tire 9 onto the surface of the top plate 11 of the main frame 1, and cooperates with the second pusher 63 to position the tire 9 so that the circular opening 101 is inside the tire 9. After the tire 9 is positioned, the first pusher 61 and the second pusher 62 are reset. Then, the lifting cylinder 16 drives the rotating worktable 4 to rise above the top plate 11 and to the inside of the tire 9.
[0057] Then, the third electric cylinder 78 drives the rotating disk 75 to rotate counterclockwise relative to the rotating worktable 4. The rotating disk 75 drives all the support heads 71 to expand outward through the drive transmission rod 74, enter the interior of the tire 9 and support the tire 9. After that, the lifting cylinder 16 drives the rotating worktable 4 to rise. After it is a certain height away from the top plate 11, it maintains the same height. Then, the rotating worktable 4 drives the tire 9 to rotate counterclockwise synchronously with it. The cutting component 5 removes the burrs on the tread and shoulder of the tire 9.
[0058] After the rotary table 4 stops rotating, the lifting cylinder 16 drives the rotary table 4 to descend. Once the bottom of the tire 9 contacts the top plate 11, the lifting cylinder 16 stops. Then, the third electric cylinder 78 drives the rotating disk 75 to rotate clockwise relative to the rotary table 4. The rotating disk 75, through the drive transmission rod 74, drives all the support heads 71 to retract inwards, disengaging from inside the tire 9 and retracting into the outer contour of the rotary table 4. Afterwards, the lifting cylinder 16 continues to drive the rotary table 4 to descend, and the rotary table 4 stops after returning to its initial position.

The longitudinal linear module 81 is used to adjust the front and rear positions of the cutting component 5, and the vertical linear module 82 is used to adjust the height position of the cutting component 5. The first servo motor 83 is used to adjust the angle and posture of the cutting component 5. In the working state, the cutting component 5 changes its trajectory and posture according to the path set by the program to complete the removal of external burrs on the tire 9.
[0062] The cutting assembly 5 includes a mounting base 51, a handle 52, and a blade 53. The mounting base 51 is fixedly connected to the output end of the first servo motor 83. One side of the handle 52 is unidirectionally rotatably connected to the mounting base 51 in an elastic fit. The blade 53 is detachably mounted on one side of the handle 52, and has a toothed cutting edge on the side opposite to the rotation direction of the tire 9.
[0063] The handle 52 is a square plate and is located on one side of the mounting base 51. Two hinge handles 54 are fixedly installed at a distance from each other on the right side of the handle 52. The ends of the two hinge handles 54 away from the handle 52 are rotatably connected to the mounting base 51 through a first pin 55. A torsion spring 56 is sleeved on the first pin 55, and its two ends abut against the handle 52 and the mounting base 51 respectively.
[0064] The right side of the slider seat is provided with a limiting part 59 to prevent the knife handle 52 from rotating in the opposite direction around the first pin 55. The limiting part 59 is arranged adjacent to the hinge handle 54. Under the action of the torsion spring 56, the hinge handle 54 is in contact with the surface of the limiting part 59. Two bearing seats are fixed on the side of the knife handle 52 away from the mounting base 51. The two bearing seats are arranged at intervals and are provided with a second pin 57. A set of rollers 58 are provided on the first pin 55. Each roller 58 is rotatably engaged with the knife handle 52 through the second pin 57. In the working state, the movement trajectory and posture angle of the knife handle 52 and the blade 53 are adjusted by program control. The rollers 58 are in contact with the surface of the tire and cooperate with the rotation of the tire to better control the distance between the blade 53 and the tire surface, thereby improving the accuracy of the cutting height control of the tire surface burrs.
