Description

Technical Field

[0001] The present application relates to the technical field of rubber material conveying, and in particular to a double-station rubber material conveying device for tire molding. Background Art

[0002] Solid tires are widely used in various heavy machinery and industrial vehicles, such as excavators, forklifts, cranes, etc., because they do not require inflation, are wear-resistant, puncture-resistant, and crush-resistant. They have very strong wear resistance and load-bearing capacity, which can ensure work efficiency and safety; agricultural machinery also needs to travel in complex field conditions, so solid tires have become the mainstream choice in the agricultural machinery industry, such as tractors and harvesters. In the production of solid tires, a tire building machine is required, which can process raw materials (such as rubber) into tires with specific shapes and structures, and lay the rubber compound layer by layer along the circumference on the working axis of the building machine. The molds on both sides heat and press the rubber compound inward to finally form the overall shape of the tire.

[0003] The existing tire forming machine needs to continuously supply tread rubber and inner rubber when in use, and also needs to add cord layers to the tread rubber and inner rubber. However, after the inner rubber is transported to the designated work station, it is still necessary to manually cut the inner rubber with scissors, which is time-consuming and labor-intensive, and the cutting accuracy is not high. At the same time, the existing tread rubber and inner rubber output structure is generally a single-station, that is, a tread rubber conveyor line and an inner rubber, but in actual use, two layers of tread rubber conveyor lines and two layers of inner rubber are needed. Then, when the worker sticks the material into the work station of the tire forming machine to form a single tire, the two conveyor lines are repeatedly and alternately pushed out from the upper and lower sides, rather than being pushed out in sequence from top to bottom, resulting in low efficiency for workers to take the material.
