Technical Field

The invention relates to the technical field of tire production, in particular to a method for cutting a rubberized cord fabric.

Background

The cord fabric is a fabric lined in the tire and has the functions of protecting rubber and resisting tension, the cord fabric is also called cord fabric, the rubber coating is a process for covering a rubber layer on the cord fabric, the rubber coated cord fabric requires that the rubber and the cord fabric are well adhered to each other and fill the gaps of the cord fabric, and the thickness of the rubber layer is accurate and uniform.

The existing rubber-coated cord fabric needs to be supported by a backing plate when being cut off and then cut by a cutter, and because the backing plate is horizontally placed on a conveying belt and the cord fabric is thin, the cord fabric is easy to be clamped at the joint between the backing plate and the conveying belt when being conveyed in one direction, thereby causing the problem of material blockage

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides a method for cutting the rubberized cord fabric, which solves the problems that the prior rubberized cord fabric is supported by a backing plate and cut by a cutter when being cut, and the cord fabric is flatly placed on a conveying belt and is thin when the backing plate is conveyed in one direction, so that the cord fabric is easily clamped at the joint between the backing plate and the conveying belt, thereby causing the phenomenon of material blockage.

In order to achieve the purpose, the invention is realized by the following technical scheme: a method for cutting a rubberized cord fabric comprises the following operation steps:

s1, cord fabric conveying:

removing the base plate, and directly placing the rubber-coated cord fabric on a conveying belt for conveying;

s2, sucking by a sucking disc:

the vacuum chuck is vertically positioned above the rubberized cord fabric and externally connected with a vacuum generating element, the conveying of the portion, to be cut, of the rubberized cord fabric is stopped when the portion reaches the position right below the cutter through conveying, the vacuum chuck descends and is attached to the surface of the rubberized cord fabric, the rubberized cord fabric is adsorbed to the bottom of the vacuum chuck through vacuumizing, and then the rubberized cord fabric is lifted to be separated from the surface of the conveying belt;

s3, cord fabric cutting:

the cutter punctures the middle part of the rubber-coated curtain cloth and then carries out reciprocating cutting in the horizontal direction to realize cutting.

Optionally, in the step S2, after the vacuum chuck adsorbs the rubber-coated cord fabric, the vacuum chuck adsorbs the rubber-coated cord fabric and lifts it to separate it from the surface of the conveyor belt.

Optionally, in the step S3, the dividing stroke of the cutter is greater than the width of the rubberized fabric to be divided.

Optionally, the method for cutting the rubberized cord fabric is applied to the field of cutting the rubberized cord fabric in tire production.

The invention provides a method for cutting a rubber-coated cord fabric, which has the following beneficial effects:

according to the method for cutting the rubber-coated cord fabric, the rubber-coated cord fabric is adsorbed by the vacuum chuck and lifted to be separated from the surface of the conveying belt, and then is cut by puncturing the middle part by the cutter and performing reciprocating cutting in the horizontal direction, and the rubber-coated cord fabric is adsorbed by the vacuum chuck instead of removing the base plate, so that the phenomenon of material blockage can be thoroughly eradicated.
