Description

Technical Field

[0001] This utility model relates to the field of tire production equipment, and more specifically to an angle adjustment device for the tire unloading clamping block of a tire forming machine. Background Technology

[0002] As we all know, the tire bead comes into contact with the car rim and plays an extremely important role in the tire structure, especially in relation to tire safety. After the tire blank is formed, the difficulty of removing the tire and the damage to the bead caused by scraping it directly affect the tire's appearance quality and safety performance, while also restricting production efficiency.

[0003] After the tire blank is formed, it is held by two clamping blocks at the top and bottom during unloading. At the same time, the transfer ring moves to transport the tire blank to the conveyor channel. The clamping blocks are released, and the center roller pushes the tire blank to the inspection station. Different specifications of tire blanks have different circumferences. The original angle of the unloading clamping blocks is not suitable for all specifications. When the angle is not appropriate, it will cause a large difference in the concentricity between the center of the tire blank and the center of the main drum (the tooling for the tire blank material to adhere to). The circumferential distance between the tire blank bead and the main drum will be inconsistent. In severe cases, the tire blank bead will come into contact with the main drum, causing the tire blank bead to be damaged by scraping against the main drum during the transfer ring movement. The deformation of the tire blank will affect the material distribution of the finished tire, resulting in poor tire performance. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a tire unloading clamping block angle adjustment device for a tire forming machine, which solves the problem of difficulty in unloading the tire after tire forming and prevents the tire bead from being scratched during tire unloading, thus preventing damage to the tire bead.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a tire unloading clamping block angle adjustment device for a molding machine, which is provided with a tire unloading assembly. The feature is that an angle adjustment device is installed on the upper left and right sides of the tire unloading assembly. The angle adjustment device is a corner plate with a triangular cross section formed by bending a rectangular plate. Two parallel elongated adjustment slots are machined longitudinally on the side of the angle adjustment device. Fastening bolts pass through the adjustment slots to fix the angle adjustment device on the tire unloading assembly.

[0006] The beneficial effect of this utility model is that, based on the original equipment, an angle adjustment device for the tire unloading clamping block is added. On-site, the clamping angle of the two tire unloading clamping blocks can be adjusted according to the circumference of the tire blank, so that the center of the tire blank and the center of the main drum are kept concentric and the distance between the tire blank opening and the main drum is uniform, thus solving the problem of tire blank deformation caused by the tire blank colliding with the main drum during tire unloading.

[0012] In the figure: 1. Angle adjustment device, 2. Adjustment slot, 3. Tire blank unloader assembly, 4. Tire blank, 5. Fastening bolt. Detailed Implementation

[0013] In the figure, the present invention is provided with a tire unloading device assembly 3. An angle adjustment device 1 is installed on the upper part of the left and right sides of the tire unloading device assembly 3. The angle adjustment device 1 is a corner plate with a triangular cross section formed by bending a rectangular plate. Two parallel elongated adjustment slots 2 are machined longitudinally on the side of the angle adjustment device 1. Fastening bolts 5 pass through the adjustment slots 2 to fix the angle adjustment device 1 on the tire unloading device assembly 3.

[0014] When the produced tire blank 4 becomes a small diameter, loosen the fastening bolt 5 and raise the front end of the angle adjustment device 1 to a suitable angle, then tighten the fastening bolt 5 again to change the included angle, adapting to the unloading of the tire blank 4 with the current diameter; when the diameter of the tire blank 4 becomes large, loosen the fastening bolt 5 and lower the front end of the angle adjustment device 1 to a suitable angle. In this way, the angle can be changed by adjusting the height of the front end of the angle adjustment device 1 to adapt to the unloading of tires of different specifications.
