Diameter-reducing telescopic tube device for braiding machine

Abstract

The invention provides a variable diameter telescopic pipe device of a knitter, belonging to knitters. The device comprises an up-and-down reciprocating device, a passing thread supporting and positioning device, a core fixing base and a rack, wherein the up-and-down reciprocating device is connected with the passing thread supporting and positioning device; the lower end of a core pipe of the passing thread supporting and positioning device passes through the core fixing base and the rack and is connected with the rack by the core fixing base; a motor of the up-and-down reciprocating device is connected with a moving part by a moving rod lifter; a thread passing convex cap is connected at the upper end of the core pipe of the passing thread supporting and positioning device; a core sleeve is arranged below the thread passing convex cap; a core fixing rod is connected in a blind hole at the upper end of the moving rod; the core sleeve is arranged in the core pipe and is connected outside the moving rod in a sleeving manner; the core fixing rod is connected in the blind hole of the moving rod in a sleeving manner; and a fastener pushes against the core fixing rod by passing through the core pipe, the core sleeve and a sliding chute of the moving rod. The device has the advantages that the device replaces manual operation and has the effect of saving manpower and raw materials; the variable diameter pitch is uniform, no wastes appear, and the product randomly extends or shrinks without deformation; and the product quality and yield are increased.

Description

technical field [0001] The invention relates to a variable-diameter telescopic tube device, in particular to a variable-diameter telescopic tube device for a braiding machine. Background technique [0002] At present, when the factory produces braided products with variable diameter and telescopic tubes, it is generally made by hand. When the workers are operating, they fix the head end of the rubber hose on a guide rod, and then the guide rod Drive the rubber hose to penetrate into the pre-prepared outer round flat plug braid, elongate the rubber hose, and fix it at both ends of the braid. When the rubber hose naturally shrinks, it drives the braid to shrink, and the braid shrinks and squeezes Under the action of pressure, uneven wrinkles are produced on the cylindrical surface of the braid, and finally a diameter-sized outer surface is formed, which makes the rubber hose shrink in diameter. [0003] Disadvantages: uneven pitch of variable-diameter expansion tubes, unstabl...
