Draughting mechanism capable of preventing slip and pultrusion machine

Abstract

The invention relates to a slipping-proof traction mechanism and a pultrusion machine, and relates to a device which causes a glass yarn and a glass felt to be composite and thermoplastic to a continuous profile, wherein, the traction mechanism consists of a first traction mechanism and a second traction mechanism, a thermoplastic molding die part consists of a first thermoplastic molding die mechanism and a second thermoplastic molding die mechanism; a chain row transmission part consists of a lower chain row which is driven by power source, and an upper chain row which matches and connects with the lower chain row to form an extruding construction; a traction speed detecting mechanism which detects the traction speed of the chain row is arranged at the power output end of the lower chain row and is connected with the electric control system of a machine unit in an electric apparatus way; a product on-line speed detecting device which detects the output speed of the product is arranged at a product output part which is adjacent to a chain row transmission part, and is connected with the electric control system of the machine unit in an electric apparatus way. The single-machine double-line traction device has high productivity rate, can achieve the on-line detection and eliminate the slipping phenomenon as the product is pulled and extruded, thereby ensuring the traction effect.

Description

technical field [0001] The invention belongs to the field of pultrusion molding equipment for composite materials, and relates to equipment for thermally molding glass yarn and glass felt into continuous profiles, in particular to a traction mechanism capable of preventing slipping and a fiberglass pultrusion molding machine thereof. 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 mech...

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 meet the needs of large-scale production;

[0008] It is known that the traction mechanism is prone to "slip" phenomenon caused by insufficient traction, which affects the pultrusion effect
