A manufacturing device of tpu waterproof composite cloth with strong connection and long service life

Abstract

The invention relates to the technical field of TPU composite cloth making and discloses TPU waterproof composite cloth firm in connection and long in service life. A shell is included, and a liquid flowing plate is in sliding connection in the shell; an extruding plate is movably connected to the bottom of the liquid flowing plate; a supporting frame is hinged to the end, away from the shell, ofthe extruding plate; a liquid flowing channel is fixedly connected to the surface of the supporting frame; and the positions, located on the two sides of the liquid flowing channel, of the surface ofthe supporting frame are each fixedly connected with an exhausting plate. Gas brought in by melt flowing through the liquid flowing channel is sucked to enter a sucking pipeline; air flow which is sucked in can flow out of an only outlet, namely the surfaces of the exhausting plates, and melt, falling onto fabric, on the containing surface is blown, the air flow reaches the fabric surface later than the melt, and therefore the effects of eliminating bubbles and improving compacting and bonding degree are achieved; and the air flow bears pressure and has certain heat and flow speed, and therefore the effect of downward pressing force is achieved on the melt attached to the fabric surface.

Description

technical field [0001] The invention relates to the technical field of making TPU composite cloth, in particular to a manufacturing device for TPU waterproof composite cloth with firm connection and long service life. Background technique [0002] Composite fabric is to use TPU film to compound on various fabrics to form a composite material, and combine the characteristics of the two to obtain a new type of fabric. [0003] There are two methods for composite fabrics, one is called post-lamination: first make a TPU film and then glue it on the fabric, and the other is called online composite: apply glue on the fabric or not glue it, and directly put TPU on the fabric The top is made of TPU composite fabric or sandwich cloth. [0004] After experimental comparison, it is found that the online lamination method is better than the post-lamination method, and the composite fabric produced is also more durable. Inject gas, so that the composite film successfully produced in th...

Problems solved by technology

[0004] After experimental comparison, it is found that the online lamination method is better than the post-lamination method, and the composite fabric produced is also more durable. Inject gas, so that the composite film successfully produced in the later stage contains air bubbles. If the bubbles are not eliminated, it will affect the degree of adhesion of the composite film and affect the service life. Therefore, a manufacturing device for TPU waterproof composite cloth with firm connection and long service life Came into being
