Traction mechanism for composite material pulling extruding machine and pulling extruding machine thereof

Abstract

The invention relates to a traction mechanism of a composite material pulling and extruding machine as well as the pulling and extruding machine, in particular to a piece of equipment for hot molding glass yarns and glass mats into continuous profile material; wherein, the traction mechanism comprises a first and a second traction mechanism, one end of a thermoplastic forming mold is adjacent to the traction mechanism, and the other end is adjacent to a dip coating member; the thermoplastic forming mold comprises a first and a second thermoplastic forming mold mechanisms, which are of the identical structure and fixedly arranged respectively; a transmission member comprises a lower chain and an upper chain fitted and combined with the lower chain to form an extruding structure, thus constructing a chain transmission member, and the upper chain is arranged in a manner so that the upper chain can press or release the lower chain by the drive of a cylinder in a pneumatic pressing device; a traction speed detecting mechanism is arranged at the power output end of the lower chain and connected with a machine electric control system; a workpiece online speed detecting device is arranged on a workpiece output part and connected with the machine electric control system. The one-machine and two-channel traction equipment in the embodiment has the advantages of enjoying high production efficiency, realizing online detection, eliminating the slipping defects arising during the extrusion of the workpiece, and guaranteeing the traction effects.

Description

technical field [0001] The invention belongs to the field of pultrusion molding equipment for composite materials, and relates to a device for thermally molding glass yarn and glass felt into continuous profiles, in particular to a fiberglass pultrusion molding machine with a double-path pultrusion structure and its traction mechanism . Background technique [0002] In the known FRP pultrusion molding machine, the glass yarn and the glass felt are released freely from the creel and the felt frame respectively by the traction mechanism, so that the glass yarn and the glass felt are dipped in the glue solution through the glue tank, and then passed through the pultrusion tooling frame. The yarn plate and felt sleeve on the upper part enter the mold after pre-forming the mold. The mold is surrounded by the heating sleeve and heated. The glass yarn and glass felt soaked in the glue are solidified and formed through the inner cavity of the mold, and are drawn out by the traction ...

AI Technical Summary

Problems solved by technology

[0007] The known technology is generally in the form of a single unit and a single head, that is, a traction mechanism, an intermediate frame, a thermoplastic molding mold part, a dipping part, a felt feeding mechanism, and a yarn feeding mechanism to form a pultrusion molding system. , so the equipment occupies a large area, it is difficult to reduce the energy consumption of the whole machine, and it is difficult to adapt to the needs of large-scale production; the known traction mechanism is prone to "slip" phenomenon caused by insufficient traction force, which affects the pultrusion effect
