AI Technical Summary

Technical Problem

The existing polyester filament tangent method can easily lead to a rise, causing the inner part of the polyester filament to be separated, and the tensioned line after the tangent is naturally falling off and displaced. Especially when the winding tension is tight, the line needs to be threaded again, which is inconvenient.

Method used

A tangent assembly for winding polyester filament is designed, including a bracket, lead assembly, drive mechanism, clamping sleeve, wheel, tangent assembly, etc. The wire is passed through the wheel inside the wire box through the pulling of the lead assembly. The second motor drives the wire barrel to automatically wind up, the cylinder pushes the rod upward, the jacket drives the capacitor wire and the heater downward, the rack drives the gear to rotate, the reverse screw rotates, the clamp rod approaches, the clamping rod clamps the wire to the wheel, and the capacitor wire cuts the wire.

Benefits of technology

It realizes rapid and efficient cutting of the wire without falling off and displacement, making it more convenient to thread and wind up, and the slag on the surface of the capacitor wire can also be cleaned, avoiding the problem of excessive slag adhesion during the tangent process.

Abstract

The invention relates to the related technical field of polyester filament processing, in particular to a polyester filament winding thread cutting assembly which comprises a support, a top seat fixedly mounted at the top end of the support, a thread guiding assembly arranged on the lower surface of the top seat, a sliding seat connected to the inner side of the top seat through an arranged driving mechanism, and a connecting seat fixedly mounted on the outer side of one end of the sliding seat. A supporting rod is fixedly installed on the outer side of the connecting base, assembly frames are installed on the outer walls, close to the lower end, of the two sides of the supporting rod correspondingly, a transverse rod and a first roller rod are sequentially arranged on the inner sides of the two assembly frames from top to bottom, connecting rods are fixedly installed on the outer sides of the two ends of the transverse rod correspondingly, and a second roller rod is jointly arranged between the two connecting rods. A wire box is jointly installed on the outer side of the first roller rod and the outer side of the second roller rod through arranged clamping sleeves, a wire clamping piece is arranged on the inner side of the wire box, a base is fixedly installed on the edge of one end of the wire box, and U-shaped tables are installed on the upper surfaces of the two ends of the base correspondingly. And the problem that wire cutting is strenuous due to excessive adhesion of molten slag in the wire cutting process is solved.
