Description

Technical Field

[0001] The utility model relates to the technical field of tire production, in particular to a tire retreading device. Background Art

[0002] After the tire is vulcanized into a finished tire, it needs to be warehoused after the tire information is read by scanning the barcode. However, some tires on the conveyor belt need to be turned over to expose the barcode for the automatic barcode scanning by the barcode scanner. Therefore, these tires that cannot be scanned need to be diverted by the conveyor belt and then transported to the tire turning device for turning over.

[0003] In the prior art, the tire turning device usually uses a clamping jaw turning device to turn over the tire belt. However, the tire specifications are diverse, and the clamping jaw turning method often fails to firmly grasp the tire, making it impossible to effectively turn over the tire, or the clamping is too tight, resulting in damage to the tire surface and affecting the product quality. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art that the clamping jaw turning method often fails to firmly grasp the tire, making it impossible to effectively turn over the tire, or the clamping is too tight, resulting in damage to the tire surface and affecting the product quality, the utility model provides a tire retreading device.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a tire retreading device, including a retreading frame, a linkage shaft is rotatably arranged on the upper side of the retreading frame, two retreading plates are arranged oppositely on the linkage shaft, one ends of the two retreading plates far away from the linkage shaft are connected with retreading rods, a cross brace is arranged on the retreading frame, two cylinders are arranged on the cross brace, the positions of the two cylinders correspond to the positions of the retreading plates, speed regulating valves are arranged at the air inlets and outlets of the cylinders, the cylinder body of the cylinder is hinged to the cross brace in the horizontal direction, and the output end of the cylinder is hinged to the retreading plate in the horizontal direction. A roller conveyor belt is arranged below the cross brace, a column is arranged at the lower end of the retreading frame, a foot support is arranged at the lower end of the column, and the height between the column and the foot support is adjustable.

[0006] The roller conveyor belt is used to convey tires. When the tire impacts the tire turning rod, the tire turning rod moves along an arc path with the linkage shaft as the rotation center, and one side of the tire is lifted. The roller conveyor belt continuously applies a thrust to the tire, making the angle at which the tire is lifted by the tire turning rod higher and higher. The tire gradually stands up and falls to the other side, completing the turning; after the tire is turned over, it falls on the roller conveyor belt and continues to be conveyed. The tire turning rod and the tire turning plate drop to the initial position by their own gravity and wait for the next tire; the height between the column and the foot support is adjustable, which is used to adjust the initial height of the tire turning rod in the state where the air cylinder contracts, ensuring that when the tire turning rod contacts the tire, it can lift one side of the tire and preventing slipping between the tire turning rod and the tire, which may cause the turning to fail; speed regulating valves are arranged at the air inlet and outlet of the air cylinder to throttle the air intake and exhaust of the air cylinder. The air intake throttling is used to maintain the clamping force of the tire turning rod on the tire when the tire turning rod lifts one side of the tire, and the air exhaust throttling is used to control the falling speed of the tire turning plate and the tire turning rod by their own gravity; the conveyor belt is a roller conveyor belt. The tire is placed flat on the conveyor belt and conveyed towards the tire turning device. When the output end of the air cylinder extends and the tire turning rod lifts one side of the tire, the other side of the tire can be stuck between the two rollers, preventing the contact surface between the tire and the conveyor belt from slipping.

[0007] Further, in order to adjust the heights of the column, the tire turning frame and the tire turning rod, a chute cooperating with the column is provided on the foot support. A support bolt facing upward is fixedly connected to the bottom of the chute. A through hole cooperating with the support bolt is provided at the bottom of the column. A nut for adjusting the height of the column is provided on the support bolt. By adjusting the position of the nut on the support bolt, the height of the bottom end of the column from the ground can be adjusted.

[0008] Further, in order to ensure that the height between the column and the foot support is adjustable while increasing the connection stability between the column and the foot support, a strip-shaped hole is provided on the side wall of the chute along the vertical direction. A connection hole cooperating with the strip-shaped hole is provided on the side wall of the column. A bolt is inserted through the connection hole and the strip-shaped hole.

[0009] Further, in order to arrange the air cylinder on the cross brace, two connection seats are provided on the cross brace. A connection sleeve is horizontally hinged on the connection seat. The connection sleeve is sleeved on the cylinder block of the air cylinder and fixedly connected to the cylinder block of the air cylinder. An avoidance groove cooperating with the cylinder block of the air cylinder is provided on the connection seat.

[0010] By hinging the connection seat and the connection sleeve, the telescopic movement of the output end of the air cylinder is smoother, without bending deformation, and the movement range of the tire turning rod is increased; by providing an avoidance groove on the connection seat, interference between the cylinder block of the air cylinder and the connection seat is avoided; by adjusting the position of the cylinder block of the air cylinder on the connection sleeve, the position state of the tire turning rod can be finely adjusted, improving the applicability of the tire turning device.

[0011] Further, the cross section of the tire turning rod is circular, and an anti-slip layer is sleeved on the outer side of the tire turning rod.

[0012] Furthermore, in order to improve the stability of the connection between the tire retreading plate and the tire retreading rod, the tire retreading plate is an arc-shaped plate, and one or more reinforcing rods are connected between the two tire retreading plates.

[0013] The beneficial effects of the present invention are as follows: the tire retreading device provided by the present invention adopts an adjustable height between the upright column and the foot support to realize the height adjustment of the tire retreading rod, so that the tire retreading rod can cooperate with tires of any specifications to retread, with a high retreading success rate, reducing tire surface damage and ensuring product quality.

[0021] The tire retreading frame 1 is provided with a cross brace 5, on which two cylinders 6 are provided. The positions of the two cylinders 6 correspond to the positions of the tire retreading plate 3. Speed regulating valves are provided at the air inlet and outlet of the cylinder 6. The cylinder body of the cylinder 6 is hinged to the cross brace 5 in the horizontal direction. The cross brace 5 is provided with two connecting seats 9. A connecting sleeve 10 is hinged to the connecting seat 9 in the horizontal direction. The connecting sleeve 10 is sleeved on the cylinder body of the cylinder 6 and fixedly connected to the cylinder body of the cylinder 6. The connecting seat 9 is provided with an avoidance groove 91 that cooperates with the cylinder body of the cylinder 6. The output end of the cylinder 6 is hinged to the tire retreading plate 3 in the horizontal direction. A roller conveyor belt is provided under the cross brace 5. The lower end of the tire retreading frame 1 is provided with a column 7. The lower end of the column 7 is provided with a foot support 8.

[0023] Working process:

[0024] Different tires have different sizes and thicknesses. Before turning tires in batches, preliminary calibration work is required, specifically adjusting the height of the tire turning rod 4 when it is at the lowest point, and adjusting the air intake speed of the air inlet and the air outlet speed of the air cylinder 6 through the speed regulating valve;

[0025] Place a sample tire on the roller conveyor belt, and adjust the height of the column 7 from the ground by cooperating with the support bolt 82 and the nut 83, thereby adjusting the height of the tire retardation rod 4 so that the height of the tire retardation rod 4 corresponds to the bottom of the tire or the longitudinal tread position, ensuring that when the tire hits the tire retardation rod 4, one side of the tire can be lifted by the tire retardation rod 4 moving along the arc path.

[0026] When the conveying speed of the roller conveyor belt remains unchanged, by adjusting the speed regulating valve of the air inlet of the cylinder 6, when the tire hits the tire folding rod 4, the tire folding rod 4 has a certain clamping force on the tire, ensuring that the tire folding rod 4 can lift one side of the tire. If the clamping force is too loose, it will cause slippage between the tire folding rod 4 and the tire. If the clamping force is too tight, it will cause deformation of the tire.

[0027] By adjusting the speed regulating valve at the air outlet of the air cylinder 6, the speed at which the tire folding rod 4 and the tire folding plate 3 fall back to the lowest point by their own weight is adjusted.

[0028] During retreading operation, several tires are placed at intervals on the roller conveyor belt. When a tire hits the retreading rod 4, the retreading rod 4 moves along an arc path with the linkage shaft 2 as the rotation center, and lifts one side of the tire. The roller conveyor belt continuously applies a thrust to the tire, making the angle of the tire lifted by the retreading rod 4 higher and higher. The tire gradually stands up and falls to the other side, completing the turning over; after the tire is turned over, it falls on the roller conveyor belt and continues to be conveyed. The retreading rod 4 and the retreading plate 3 drop to the initial position by their own gravity and wait for the next tire.
