Embodiment Construction

[0029] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0030] Orientation Definition: According to the direction of movement of the thermoplastic composite strip, the orientation close to the thermoplastic composite extrusion die is the front, and the orientation away from the extrusion die is the rear.

[0031] The thermoplastic composite strip of the present invention can be used in the manufacture of strip-shaped thermoplastic composite products and spiral tubular thermoplastic composite products, that is, the thermoplastic composite strip can be made into a strip-shaped thermoplastic composite product after shaping, or after shaping Helical tubular thermoplastic composite products are made by spiral welding.

[0032] Such as figure 1 , 2 As shown, a dry-type sizing de...

Abstract

The invention discloses a dry sizing device comprising a frame. The following components are sequentially arranged on the frame: a pre-cooling mechanism used for carrying out pre-cooling upon thermoplastic composite belt material delivered from an extrusion device, a sizing roller set used for extruding and sizing the thermoplastic composite belt material, an edge-cutting mechanism used for trimming the edge of the thermoplastic composite belt material, and a vacuum sizing mechanism used in further sizing. The pre-cooling mechanism, the sizing roller set, the edge-cutting mechanism, and the vacuum sizing mechanism are linearly arranged. With the dry sizing device, thermoplastic composite belt material sizing is precise, belt material size precision is high, and belt material surface quality is high.

Description

technical field [0001] The invention relates to a styling device, in particular to a dry styling device. Background technique [0002] Plastic-steel winding pipe is an excellent pipe with high strength, high rigidity and light weight. Its production method is to use continuous production of steel-plastic composite strips to be welded by spiral winding. A large part of the product quality and appearance of the plastic-steel winding pipe is determined by the quality of the thermoplastic composite material. Therefore, how to improve the quality and dimensional accuracy of the strip is a very critical issue. The thermoplastic composite tape after extrusion compounding is in a soft state, and needs to be shaped to obtain the desired appearance size and shape. [0003] Existing sizing is realized by a plurality of sizing molds soaked in water. The specific principle is: when the strip passes through the shaping mold, the strip is surrounded by the shaping mold and the water in...
