Rubber surface air-blowing device for drying and compounding machine

Abstract

The invention belongs to the field of accessory equipment of a drying and compounding machine, and particularly relates to a rubber surface air-blowing device for the drying and compounding machine. The rubber surface air-blowing device comprises an air tube, and further comprises air blocking rings, wherein the two ends of the air tube are supported and fixed in the forms of simple supporting beams through brackets; air inlets and air outlets are formed in the air tube; the air outlets are sequentially formed in the tube length direction of the air tube; air outlet directions of the air outlets point to the film surface direction of a film; each air blocking ring has an air feeding state and a closed state; when each air blocking ring is in the air feeding state, opening of the air blocking ring in the form of a C-shaped arc-shaped sheet is positioned at air outlet paths of the air outlets; when each air blocking ring is in the closed state, the ring body of the air blocking ring shields air outlet paths of the air outlets; and the air blocking rings are sequentially arranged in the axial direction of the air tube. The rubber surface air-blowing device can ensure that a coiled cold sealing adhesive is always in a drying state, so that the rubber surface is prevented from a reverse pasting phenomenon; and meanwhile, fixed-point drying ability is strong, so that the fixed-pointdrying purpose is realized relative to code spraying position of the film.

Description

technical field [0001] The invention belongs to the field of auxiliary equipment for drying and compounding machines, and in particular relates to a rubber surface blowing device for drying and compounding machines. Background technique [0002] The dry laminating machine is a mechanical device that coats the solvent-diluted adhesive on the substrate after it dries, and then laminates it with other films by pressure rollers. The existing problems in dry laminating production are as follows: firstly, at present, a large number of dry laminating machines use cold sealing technology, and cold sealing is to apply cold sealing glue on the inner layer of the film, and only need to add Pressing, using the viscosity of the cold sealant itself can achieve the purpose of bonding between the inner film. In the cold sealing process, in addition to the choice of cohesive force of the cold sealant and the control of solvent residues, it is also necessary to control the dryness of the col...
