Automatic splicing conveying auxiliary device of wire cord fabric cutting machine and conveying method thereof

Abstract

The invention discloses an automatic splicing conveying auxiliary device of a wire cord fabric cutting machine. The automatic splicing conveying auxiliary device comprises a linear guide rail mechanism arranged in a conveying direction and a magnetic adsorption mechanism driven by a servo control system to reciprocate on the linear guide rail mechanism; the magnetic adsorption mechanism comprises a magnetic adsorption head arranged on an acute-angle straight side edge of a wire cord fabric to adsorb the head of the wire cord fabric, and a servo motor driving mechanism for automatically adjusting a position of the magnetic adsorption head on a linear guide rail mechanism perpendicular to the conveying direction of the wire cord fabric according to a sensor feedback signal of detecting a position of the other straight side edge of the wire cord fabric; a conveying method of the automatic splicing conveying auxiliary device comprises the following steps that: the magnetic adsorption head adsorbs a wire cord fabric to a seaming position at a constant conveying speed; after releasing the wire cord fabric, the magnetic adsorption head returns to an initial position to wait for delivery of next wire cord fabric, and the process is circulated continuously until conveying and splicing of the wire cord fabrics are completed automatically. The automatic splicing conveying auxiliary device of the wire cord fabric cutting machine has the advantages of improving the accuracy of butting of heads and tails of wire cord fabrics, improving the quality of splicing, improving the reliability of equipment and reducing artificial auxiliary time.

Description

technical field [0001] The invention relates to tire semi-finished product production equipment, in particular to an automatic splicing and feeding auxiliary device and a feeding method for a steel cord cutting machine. Background technique [0002] In the existing manufacturing process of all kinds of all-steel and semi-steel tires, it is necessary to cut, joint and bond the various rubber parts constituting the tire, so as to form the structure of the crown and sidewall of the tire. [0003] At present, the traditional steel cord cutting machine cutting and splicing scheme includes a feeding conveying device before splicing, an independent splicing conveyor belt, a splicing device and a splicing unloading device. [0004] The conventional cutting and splicing scheme is: the feeding and conveying device before splicing conveys the head of the cut steel cord to the static splicing conveyor belt, and connects with the tail of the previous piece of steel cord positioned on the...

AI Technical Summary

Problems solved by technology

[0005] The main disadvantage of the above-mentioned splicing device is that it is difficult to align the head of the rear steel cord with the tail of the previous steel cord due to the influence of different conveyor belt resistances

[0006] The reason is: the steel cord is conveyed from the feeding conveying device to the splicing conveyor belt. Since the steel cord slides relative to the stationary splicing conveyor belt surface, for the steel cord with too long hypotenuse or the cutting angle is greater than 45°, the steel cord head Poor tail alignment, resulting in splicing deviations
