Embodiment Construction

[0021] The invention is mainly applied to the surface printing process improvement of all-plastic sheets, and the manufacturing process has been changed. In order to meet the process requirements and the barrier property requirements of the hose, firstly, the inner printing technology is used, combined with the imaging principle of the surface printing, to manufacture plastic hoses. After compounding, the ink layer is in the direction of the surface film of the composite sheet. After the compounding is completed, the pattern of the original manuscript can be reproduced very well. After cutting, the surface is printed with varnish, which can achieve more Good printing effect.

[0022] Such as figure 1 As shown, the structure of the plastic hose includes from outside to inside: the first layer is a plastic surface layer, which is a thermoplastic polyethylene film layer; the second layer is a first adhesive layer, which is a transparent adhesive resin layer; the third layer It i...

Abstract

The invention relates to a novel manufacturing process of a plastic tube. The manufacturing process firstly utilizes a reverse printer combined with the surface printing and imaging principle to carry out surface printing to a block layer used for manufacturing the plastic tube; preferably, after surface printing, the manufacturing process also comprises the following steps of: a, obtaining a composite sheet rolling film by extruding and compositing; b, welding two sides of the composite sheet rolling film for manufacturing a tube, thus obtaining a tube body; c, casting the shoulders on the tube body obtained in the step b by extruding and injecting; and more preferably, the manufacturing process further comprises the step between the step a and the step b of carrying out varnish printing on the surface of the composite sheet material film by utilizing a surface printer. The invention further provides a plastic tube manufactured by the manufacturing process. The plastic tube has skillful design of the manufacturing process, greatly improves the production efficiency and reduces the production cost, and the appearance of the produced flexible tube is delicate.
