Description

Belted layer feeding system of tire building machine, control method and application thereof
Technical Field
The invention relates to a feeding system, in particular to a novel belt feeding system of an agricultural radial tire building machine, a control method and application of the novel belt feeding system, and belongs to the field of industrial tire production.
Background
According to different tire manufacturing processes of various tire factories, tires of the same specification comprise different belted layers, so that the conveying layers of the belted layer feeding system are different, and about 4 layers are common in the industry.
The material conveying mode of the belt ply feeding system is divided into power conveying and unpowered conveying, wherein the power conveying drives a conveying belt or a conveying roller to move materials upwards and forwards under the action of power mechanisms such as a motor and the like; the unpowered conveying means that after the belt is manually fitted on the drum, the belt is driven by the rotation of the belt drum to pull the material to move forward. From the perspective of tire quality control in tire factories, there is a strict control index for the tensile amount of materials (especially for thin, wide, and soft materials), and from the material conveying manner of the existing belt ply feeding system in the industry, it is obvious that the power conveying manner can more effectively control the tensile amount, and is also more favored by each tire factory. However, since the power transmission method necessarily requires the assistance of a power mechanism, how to control the cost while meeting the quality requirements of the tire factories becomes a problem to be solved by each equipment supplier.
The existing solution in the industry is to use a servo motor to drive each layer of conveying bat. The patent names of the related utility model are: a belt ply feeding frame of an all-steel radial tire forming machine for preventing material stretching. The applicant: shenyang blue English Industrial Automation Equipment, inc. Application publication No. CN 109849394A. Although the solution is designed with the servo motor to solve the problem of passive stretching of the material on each layer of conveying bat, on one hand, the overall production cost of the equipment is greatly increased, and the cost is finally transferred to customers and consumers. On the other hand, the effective utilization rate of the equipment is reduced. Namely, a certain safety factor must be left in the industry when the servo motors are selected, namely the actual utilization rate of each servo motor is about 30%, and because each layer of conveying beat of the belted layer feeding system cannot convey materials simultaneously in the tire making process, only one layer of conveying beat conveys the materials in the same time period, taking 4 layers of conveying beats as an example, the actual utilization rate of a single-tire servo motor in the tire making process is 1/4 × 30% =7.5%.
