Embodiment 1

[0025] see figure 1 , the present invention provides a technical solution: a printing machine high-strength aramid printing guide belt, the preparation method is as follows:

[0026] Step 1: Material preparation: fabric base material for guide belt; base material is base cloth, aramid cloth, mesh cloth; 1 layer of base cloth, 1 layer of aramid cloth, 2 layers of grid cloth, aramid cloth as printing guide belt tension layer;

[0027] Step 2: Cloth cutting: the base cloth and grid cloth are cut at a shrinkage rate of 8%, and the aramid cloth is cut at a shrinkage rate of 5‰;

[0028] Step 3: Layered lamination: Under the pressure of 13MPa and the temperature of 110°C, lamination is carried out every 2 layers, and the interlayers are bonded without glue, and the conduction tape is not easy to delaminate;

[0029] Step 4: Make joints: automatic punching, ironing, applying adhesive, and fixing the joints; the base layer needs to be leveled before applying the adhesive, and the co...

Abstract

The invention discloses a high-strength aramid fiber printing conduction band of a printing machine. A preparation method comprises the following steps that 1, material preparing, wherein the conduction band is made of a cloth base material, and the base material is composed of bottom layer cloth, aramid fiber cloth and gridding cloth; 2, cloth cutting, wherein the bottom layer cloth and griddingcloth are blanked according to the shrinkage rate of 8%, and the aramid fiber cloth is blanked according to the shrinkage rate of 0.5%; step 3, laminating in a layered manner, wherein laminating of every two layers is carried out; 4, joint fixing, wherein automatically punching teeth, ironing, coating of an adhesive, and joint fixing are carried out; step 5, surface glue coating, wherein uniformlycoating of the surface of a structural cloth with a calendered glue sheet is carried out, and low-temperature compaction is carried out; step 6, vulcanizing, wherein vulcanizing of a formed conduction band coated with a glue sheet is carried out. According to the invention, every two layers are laminated under the pressure of 13-17MPa and at the temperature of 110-130 DEG C, and the layers are bonded without glue, so that the conduction band is not easy to layer; the aramid fiber printing conduction band produced in an extrusion calendering mode is large in density, high in temperature resistance and smoother in surface; the conduction band is more compact in structure and more resistant to corrosion; the molecular fluidity is reduced, and the interface is firmer.

Description

technical field [0001] The invention belongs to the technical field of printing guide belts, in particular to a high-strength aramid printing guide belt for printing machines. Background technique [0002] Different from the traditional rubber belt, the new generation of printing belt strength layer is made of Polyester or Aramid. Features of aramid printing guide belt: Aramid material: flat screen suitable for dual motor servo drive, longer size guide belt, generally the length of the guide belt is more than 45 meters. [0003] The existing printing guide belts have problems of low strength, unevenness and delamination of the guide belts during preparation. [0004] In order to increase the strength and flatness of the printing belt and reduce the delamination of the belt, we propose a high-strength aramid printing belt for printing machines. Contents of the invention [0005] The purpose of the present invention is to provide a high-strength aramid printing guide belt ...
