Pneumatic cloth pressing device for composite production line

Abstract

The invention discloses a pneumatic cloth pressing device for a composite production line for cables and electric materials. The pneumatic cloth pressing device comprises pinch rolls located in front of drying cylinders (1) of a dryer and a press roll (2) located above the drying cylinders (1), wherein the pinch rolls comprise an upper pinch roll (3) and a lower pinch roll (4) which are fixed up and down, a roll shaft of the upper pinch roll (3) is fixed in a through hole of a pinch roll slider (31), a roll shaft of the lower pinch roll (4) is fixed on a pinch roll slider fixing seat (32), and a roll shaft of the press roll (2) is fixed in a through hole of a press roll slider (21). The pressure between the pinch rolls and the pressure between the press roll (2) and the corresponding drying cylinder (1) are adjusted, and pressure is applied to a base material in operation through the pressure, so that the thickness uniformity of composite cable and electric material products can be improved. The reject ratio of the products is reduced, and the production cost is saved.

Description

technical field [0001] The invention relates to a cloth pressing device, in particular to a pneumatic cloth pressing device used in a composite cable and electric material production line. Background technique [0002] The manufacture of semi-conductive double-sided water-blocking tape and semi-conductive double-sided buffer water-blocking tape is completed on the composite production line. The two kinds of raw material cloth are unwound through the unwinding machine, glued on the glue roller, powdered by the powder roller, Composite roll compounding and other processes, enter the dryer to dry and shape, then wind up, cut, and process into semi-finished cables and electrical materials. [0003] At present, in the production process of domestic semi-conductive double-sided water-blocking tapes, semi-conductive double-sided buffer water-blocking tapes and other cable materials, the technical parameters of the products can basically meet the standards, but the thickness uniform...

Problems solved by technology

[0003] At present, in the production process of domestic semi-conductive double-sided water-blocking tapes, semi-conductive double-sided buffer water-blocking tapes and other cable materials, the technical parameters of the products can basically meet the standards, but the thickness uniformity of the products and the thickness requirements of special products are limited. hard to guarantee

This is mainly due to the relatively large thickness tolerance and poor thickness uniformity of the raw material cloth (such as needle-punched glue-sprayed fluffy cotton). When the thickness is often easily out of tolerance
