Abstract

The utility model belongs to a mechanical device, which is used for winding glass fiber rolls. The utility model mainly comprises a machine body, a ball screw which is driven by a motor, and a rolling guide rail. A screw nut on the screw is fixedly connected with a slide block which is fixedly connected with a wiredrawing machine head. A glass fiber wire distributing device which is driven by the motor is arranged above a reel of the wiredrawing machine head. The utility model alters the screw nut of the original screw. The slide guide rail adopts rolling friction. Transmission efficiency is improved to more than 90 percent from 40 percent. The utility model reduces the abrasion of work pieces, overcomes the phenomena of lateral gaps, reversal idle running, and creeping of the original slide guide rail, and improves the accuracy of the reciprocating movement of the wiredrawing machine head.

Description

The glass fiber wire-drawing machine

The glass fiber wire-drawing machine is a kind of with the glass solution in the industry kiln pond, or the glass solution that glass sphere places the crucible internal heating to form draws the mechanical means that is fiber and turns to fiber roll according to certain rules.

The glass fiber wire-drawing machine can be divided into two classes with regard to the drawing mode of glass fibre at present, one class is that the rotating drum on the mandrel does not have axially reciprocating with respect to the strand oscillator of glass fibre, therefore the fiber roll axial width of coiling is limited by the swing fabric width of strand oscillator discharging glass fibre, the just essential strand oscillator and the mandrel reel of changing different size of glass fibre volume of coiling different size; Another kind of be rotating drum on the mandrel in twining the process of glass fibre also with respect to the strand oscillator axially reciprocating, therefore need not change the fiber roll that strand oscillator just can the coiling different specification size, to adapt to the demand of market to specification glass fiber roll how wide in variety, obviously than the first kind tangible technical superiority is arranged, as homemade 9042LX1 type large package glass fiber wire-drawing machine, be exactly to support the mandrel to-and-fro movement with feed screw nut and rail plate, draw in the winding process, the linear velocity of glass fibre winding displacement is very high, very high to mandrel to-and-fro movement accuracy requirement, otherwise be easy to cause glass fibre coiling system irregular, waist is protruding or waist is recessed, influence quality product, because feed screw nut and rail plate are the sliding friction kinematic pairs, have side play, reverse idle running and creeping phenomenon, the big consumed power of friction resistance, kinematic pair is easy to wear, makes maintenance difficulty big, the expense height, increase production cost, influence the output and the quality of product.

Shortcomings and deficiencies at above-mentioned glass fiber wire-drawing machine existence, the purpose of this utility model is, on the basis of homemade 9042LX1 type large package glass fiber wire-drawing machine, improve the reciprocating transmission rig of mandrel, reduce the kinematic pair friction, improve head to-and-fro movement precision and quality product.

The utility model takes following technical scheme to realize above-mentioned purpose: complete machine comprises fuselage, underbelly is established a leading screw drive-motor, paying leading screw through the one-level belt transmission connects, nut and leading screw form the feed screw nut kinematic pair, the guide rail formation guide rail movement that nut and slide block connect firmly on bone piece and the fuselage is paid, connect firmly mandrel on the slide block, mandrel is made up of the superincumbent reel of motor, shaft coupling, drum shaft and installation, the reel top is the glass fibre strand oscillator, and the motor that is fixed on back is paid the connection of strand oscillator axle by the one-level belt.Technical characterstic of the present utility model is that the feed screw nut kinematic pair adopts ball screw arrangement, and adjusting bolt or nut pre-tightening mechanism are set; Guide rail movement is paid and is adopted the rolling guide structure, is provided with equally to regulate the bolt pre-tightening mechanism.

The ball-recirculation gigback of ball-screw has two kinds, and the one, the external cannula type ball-returning device of nut, or establish in the nut and oppositely return the pearl circular groove.

Between the guide rail and slide block of rolling guide, principal plane is provided with one group of circulation roller, and two sides respectively are provided with two row's circulating balls.

This glass fiber wire-drawing machine, after changing the reciprocating transmission rig of mandrel into rolling resistance by sliding friction, transmission efficiency is brought up to more than 90% by 40%, reduced machine members, annual about 20,000 yuan of the maintain and replace expenses that reduce are through adjusting pretension, the side play and the feed screw nut gap of slide block have been eliminated, improved the to-and-fro movement precision of mandrel, thereby improved the coiling quality of glass fibre volume, made product improve a grade.
