An oblique cone guide pin type one-section drum left and right turn-up capsule drum mechanism

Abstract

The invention relates to a machine for preparing rubber tires and discloses an oblique cone guide pin type one section drum left and right turn up bladder drum mechanism. The oblique cone guide pin type one section drum left and right turn up bladder drum mechanism comprises a horizontally-placed main shaft, a forming drum plate arranged on the surface of the middle section of the main shaft and two turn up side drums which are symmetrical in structure and are arranged at the left end and the right end of the main shaft. Each turn up side drum comprises a plurality of turn up drum plates uniformly distributed on the circumference of the surface of the main shaft, a turn up bladder and a turn up drum plate radial swelling-shrinking movement device. When the turn up drum plates are in a radial swelling state, the outer diameter of the turn up bladders on the outer sides is the same as the swelling outer diameter of the forming drum plate, so that the turn up bladders and the forming drum plate are connected into a straight line, the problem that the two ends of a rubber paste layer are droopy when the rubber paste layer is pasted in the prior art is solved, the pasting effect is improved, and meanwhile, the phenomenon that the two ends of the rubber paste layer are folded in the turn up process is avoided.

Description

technical field [0001] The invention relates to a rubber tire building machine, in particular to a turn-up function when a section of a tire carcass is fitted with a drum, and the function of extending a section of the diameter-reduced drum plate is added to avoid the sagging of the rubber bonding layer This phenomenon improves the quality of the tire rubber layer pasting. Background technique [0002] With the continuous growth of domestic automobile sales, the tire manufacturing industry is also growing at a rapid rate. As a standard component of tire manufacturing equipment, tire turn-up drum plays an important role in tire molding. A section of tire diameter shrinking drum is used as the equipment for pasting the tire rubber layer. Due to the limitation of the overall structure, the length of the forming drum plate will be shorter than the length of the rubber adhesive layer. Therefore, when the rubber adhesive layer is pasted, the two ends of the rubber adhesive layer w...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the defects of the prior art, to provide an oblique cone guide pin-type one-section drum left and right turn-around capsule drum mechanism, which solves the problem that the two ends of the rubber adhesive layer appear when pasting the rubber adhesive layer in the prior art. There is a problem of sagging, which improves the effect of pasting, and at the same time avoids the folding phenomenon at both ends of the rubber pasting layer during the turning-up process
