Description

Technical Field

[0001] This utility model relates to the field of vulcanizing machine technology, specifically to a quick capsule changing device for the central mechanism of a vulcanizing machine. Background Technology

[0002] The bladder is a key component in the tire vulcanization process, used to transport high-temperature, high-pressure media to shape and vulcanize the tire carcass. Due to repeated stretching, folding, and thermal cycling, the bladder is prone to aging and rupture, with an average lifespan of only about 200–300 vulcanization cycles, requiring frequent replacement.

[0003] Traditional replacement of the center mechanism capsule uses a T-thread connection to the lower clamp. Usually, after cooling, the lower clamp needs to be manually removed by rotating it with a special lever tool. This is time-consuming, labor-intensive, and can easily damage the seal, affecting tire quality. Utility Model Content

[0004] The purpose of this invention is to provide a quick capsule changing device for the central mechanism of a vulcanizing machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick capsule changing device for the central mechanism of a vulcanizing machine, comprising:

[0006] The lower clamping plate has pins threadedly connected to its lower left and right sides. Each pin includes a pin body, and the bottom end of the pin body is provided with an inverted T-shaped head.

[0007] The ring seat has receiving holes on its upper left and right sides corresponding to the positions of the pins. A locking sleeve is fixed at the bottom of the ring seat corresponding to the receiving holes. A clamping jaw is installed inside the locking sleeve. The T-shaped head is nested in the wedge-shaped jaw piece at the top of the clamping jaw. A cylinder is connected to the bottom of the locking sleeve. A hydraulic cylinder is connected to the bottom of the cylinder. A locking lever is connected between the telescopic end of the hydraulic cylinder and the clamping jaw.

[0008] Furthermore, a threaded hole is provided on the lower side of the lower clamping plate corresponding to the position of the pin, and a threaded head is provided at the top of the pin body. The threaded head is nested in the threaded hole, making the connection between the pin and the lower clamping plate simple and stable.

[0009] Furthermore, the inner cavity of the locking sleeve communicates with the receiving hole, and the nail body is nested in the receiving hole, which simplifies the structural design and reduces manufacturing costs and assembly difficulty.

[0010] Furthermore, an axial sealing ring is provided between the lower clamping plate and the ring seat to effectively prevent leakage of the internal pressure medium and improve safety.

[0011] Furthermore, the axial sealing rings are provided in pairs, providing double sealing protection and improving sealing performance and safety.

[0012] Furthermore, a positioning platform is provided on the ring seat to ensure accurate alignment between the lower clamp and the ring seat, thereby improving the accuracy and efficiency of assembly.

[0013] Furthermore, the locking rod is nested inside the cylinder, saving space.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. By threading a pin to the bottom of the lower chuck, and using a hydraulic cylinder to drive the wedge-shaped jaws of the gripper to automatically clamp and release the pin, the lower chuck can be clamped or released quickly, greatly shortening the changeover time and improving production efficiency.

[0016] 2. By controlling the clamping and releasing of the grippers with hydraulic cylinders, manual operation is reduced, operational risks are lowered, the labor intensity of workers is reduced, and safety risks caused by improper manual operation are also reduced. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figures 1 to 4 The quick capsule changing device of the central mechanism of the vulcanizing machine shown includes:

[0026] The lower clamping plate 1 has pins 2 threadedly connected to the left and right sides of its lower side. The pins 2 include a pin body 11, and the bottom end of the pin body 11 is provided with an inverted T-shaped head 12.

[0027] The ring seat 3 has receiving holes 4 on its upper left and right sides corresponding to the positions of the pins 2. The bottom of the ring seat 3 is fixed with a locking sleeve 5 corresponding to the receiving holes 4. The locking sleeve 5 is equipped with a clamping claw 6. The T-shaped head 12 is nested in the wedge-shaped claw plate at the top of the clamping claw 6. The bottom of the locking sleeve 5 is connected to a cylinder 7. The bottom of the cylinder 7 is connected to a hydraulic cylinder 8. The telescopic end of the hydraulic cylinder 8 is connected to the clamping claw 6 with a locking pull rod 9.

[0028] A threaded hole is provided on the lower side of the lower clamping plate 1 corresponding to the position of the pin 2. The top of the pin body 11 is provided with a threaded head 13, which is nested in the threaded hole, making the connection between the pin 2 and the lower clamping plate 1 simple and stable.

[0029] The inner cavity of the locking sleeve 5 is connected to the receiving hole 4, and the nail body 11 is nested in the receiving hole 4, which simplifies the structural design and reduces manufacturing costs and assembly difficulty.

[0030] An axial sealing ring 10 is provided between the lower clamping plate 1 and the ring seat 3 to effectively prevent leakage of internal pressure medium and improve safety.

[0031] The axial sealing rings 10 are provided in pairs, providing double sealing protection and improving sealing performance and safety.

[0032] A positioning platform is provided on the ring seat 3 to ensure accurate alignment between the lower clamping plate 1 and the ring seat 3, thereby improving the accuracy and efficiency of assembly.

[0033] The locking lever 9 is nested inside the cylinder 7, saving space.

[0034] In this invention, a threaded hole is machined on both the left and right sides of the lower clamping plate 1. During installation, the threaded head 13 of the pin 2 is threaded into the threaded hole. Then, the lower clamping plate 1 is aligned with the positioning platform on the ring seat 3 and inserted. The T-shaped head 12 of the lower part of the pin 2 passes through the receiving hole 4 on the ring seat 3 and is nested in the locking sleeve 5. At this time, the pin body 11 of the pin 2 is nested in the receiving hole 4, and the T-shaped head 12 is nested in the wedge-shaped claw plate at the top of the jaw 6 in the locking sleeve 5. The oil cylinder 8 at the bottom of the cylinder 7 drives the jaw 6 through the locking rod 9. The wedge-shaped mechanism of the jaw 6 radially contracts to clamp the T-shaped head 12 of the lower part of the pin 2, thereby achieving locking. By converting the small axial hydraulic driving force into a strong radial clamping force, the firm clamping and tight fit ensure the stability of the lower clamping plate 1 in each lifting action. At the same time, the installation and operation of the quick capsule replacement device are realized in the limited space of the mechanical vulcanizing machine base, effectively solving the shortcomings of the previous central mechanism for replacing the lower clamping plate 1.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
