Description

Technical Field

[0001] The invention relates to the technical field of tire manufacturing equipment, and in particular to a deburring device for manufacturing small and medium-sized tires and a working method thereof. Background Art

[0002] In the tire production process, newly manufactured tires often have a large number of burrs, which not only affect the appearance of the tire, but also may affect the performance. Therefore, burr removal is an important process in tire production. At present, the manufacture of small and medium-sized tires mainly relies on manual burr removal in the market due to the characteristics of small batches and multiple batches. Relying on manual operation of handheld equipment, the tire is first placed on a rotating table, and a special tool is pressed on the tire to drive the rotation of the tire to remove the burrs. In order to remove the burrs from the tread and shoulder of the tire, both sides need to be completed twice, which not only increases the labor intensity of the workers, but also has low efficiency, making it difficult to ensure the quality of burr removal, as well as safety hazards. There are many uncertain factors in manual operation, and long-term work will also cause fatigue and deformation of the workers' hands, affect the uniformity of burr removal, and sometimes even produce waste tires. In addition, the rubber scraps generated during the burr removal process may pose a threat to the health of workers. Many enterprises in my country's tire industry are small and medium-sized enterprises. Due to cost constraints, these enterprises have relatively low levels of automation and integration.

[0003] The existing burr removal of small and medium-sized tires on the market has problems such as inability to remove burrs in all directions, unevenness, and low efficiency. Therefore, it is necessary to develop a device for small and medium-sized tires that can automatically remove burrs in all directions, which should ensure safe operation, reasonable structure, high reliability, and reduce costs as much as possible to maximize economic benefits.

[0032] S1. The first conveying device conveys a plurality of tires which are sequentially placed on its conveying belt from back to front. After the first tire at the front reaches the position of the lateral pushing component, the conveying belt of the first conveying device stops moving.

[0033] S2. The execution end of the lateral pushing assembly moves to the left to push the first tire to the left to the top of the main frame. After that, the execution end of the longitudinal pushing assembly moves forward to cooperate with the execution end of the lateral pushing assembly to complete the positioning of the first tire.

[0034] S3, the execution ends of the longitudinal pushing assembly and the transverse pushing assembly return to their respective initial positions and then stop. After that, the first conveying device moves the next tire on its conveyor belt to the position of the transverse pushing assembly, and the conveyor belt of the first conveying device stops moving.

[0035] S4, the actuator end of the lifting cylinder drives the rotary table to rise to the set height h through the lifting plate 1 After that, the second driving mechanism drives each support head to expand outward synchronously along the normal direction of the rotating worktable, and all the support heads enter the interior of the first tire. After reaching the position, all the support heads stop moving, and the first tire is fixed on the rotating worktable.

[0037] The longitudinal linear module and the vertical linear module drive the cutting assembly to approach the top of the first tire according to the instructions set by the PLC controller. At the same time, the first servo motor adjusts the blade angle of the cutting assembly according to the instructions set by the PLC controller. After that, the blade removes burrs on the upper shoulder, tread and lower shoulder of the first tire in sequence along the motion trajectory set by the program. After that, the cutting assembly is reset and the rotary table stops rotating.

[0038] S6, the actuator end of the lifting cylinder drives the rotary table down to the set height h 1 The second driving mechanism drives each support head to shrink inward synchronously along the normal direction of the rotating worktable and separate from the first tire. All the support heads shrink to the inner side of the outer contour line of the rotating worktable and stop moving.

[0039] S7, the actuator end of the lifting cylinder drives the rotary table to continue to descend to its initial position, and the actuator end of the longitudinal pushing assembly moves forward to push the first tire to the conveyor belt of the second conveying device, and the conveyor belt of the second conveying device conveys the first tire to the left to the collection box.

[0063] The support head 71 is fixed to one end of the sliding plate 73 away from the center of the rotating worktable 4, and its outer wall is an arc-shaped curved surface matching the internal cavity of the tire 9. A transmission rod 74 is provided above one end of the sliding plate 73 close to the center of the rotating worktable 4. The transmission rod 74 is arranged vertically, and the lower end is fixedly connected to the upper surface of the sliding plate 73.

[0064] The second driving mechanism is disposed at the center of the rotating worktable 4 , and drives all the supporting heads 71 ​​to synchronously contract or expand relative to the rotating worktable 4 . In the working state, the second driving mechanism drives all the sliding plates 73 to synchronously move through the transmission rod 74 .

[0065] Specifically, the second driving mechanism includes a rotating disk 75, a gear 76, a rack 77 and a third electric cylinder 78. The rotating disk 75 is located above the rotating table 4, and its bottom is coaxially connected to the rotating table 4 through a vertical shaft 79.

After the tire 9 is positioned, the first pushing rack 61 and the second pushing rack 62 are reset. Afterwards, the lifting cylinder 16 drives the rotating worktable 4 to rise above the top plate 11 and to the inside of the tire 9.

[0069] After the rotating table 4 stops rotating, the lifting cylinder 16 drives the rotating table 4 to descend, and the lifting cylinder 16 stops after the bottom of the tire 9 contacts the top plate 11. Then, the third electric cylinder 78 drives the rotating disk 75 to rotate clockwise relative to the rotating table 4. The rotating disk 75 drives all the supporting heads 71 ​​to retract inwards through the driving transmission rod 74, and escapes from the inside of the tire 9 and is stored inside the outer contour of the rotating table 4.
