The device which has a simple and reliable structure, adopts the installing means of one for each ingot. The utility model has automatically adjusting ability which ensures the moving stability of the close spinning grid-tubular guard, thereby enabling fine ready-made yarn quality and small difference between the ingots.

Description

A kind of tight spinning grid ring tensioning apparatus

Affiliated technical field

This utility model belongs to a kind of compact spinning isolated plant.

Background technology

Traditional ring spinning yarn machine yarn technology has had the developing history of decades in China, but because its more structural problems, determined the fiber strip after drafted between the twisting point, to have a spinning triangular zone at front roller nip, fibre bundle in this trigonum after drafted is flat bar shaped, the edge fiber is without any constraint, thus wherein a part of edge fiber one end or all break away from the main fibre bundle and form filoplume and flyings.Most edges fiber not exclusively stretches when advancing to the twisting point, so they not quite cause yarn strength to be difficult to improve to the yarn strength contribution.In order to solve this difficult problem, in recent years, a kind of compact frame spinning yarn machine of numerous and confused both at home and abroad release, this equipment mainly by negative-pressure air-flow be used for control front roller nip to the fibre bundle between the twisting point, reduce even eliminate the spinning triangular zone of ring spinner, thereby make yarn strength improve, fibrous index improves greatly.In this device, negative pressure sucking air pipe, grid ring and tensioner are nearly all arranged, wherein, grid ring is looped around on the negative pressure sucking air pipe, the smoothness of operation that the automatic adjusting of dependence tensioner comes the control mesh circle.Existing grid ring tensioner has leaf spring device, tension rail etc., and the leaf spring device is the tension force size that the elastic force of dependence leaf spring is regulated grid ring, yet owing to be subjected to the restriction in space, leaf spring to have only one deck, the uniform tension in order of grid ring is difficult to guarantee like this.The tension rail device is to rely on the gravity of tension rail to regulate the tension force of grid ring, this tensioner requires the girth of grid ring to equate, but owing to weave, reason such as arrangement, cause the grid ring girth to be difficult to guarantee consistent, the gravity of tension rail only acts on that the shortest grid ring of girth like this, and other grid ring then are the relaxed state operation, and its operation stability can't guarantee, the lighter influences yarn quality, and weight person can't normally spin.

Summary of the invention

The utility model proposes in order to address the above problem exactly, realizes its function by the structure that changes tight spinning grid ring tensioner.

The technical scheme in the invention for solving the technical problem is: the feature of this tensioning apparatus comprises tension rail, tension force pole socket, negative pressure sucking air pipe, tension spring, tension spring guide pillar, wherein, the tension force pole socket is fixed on the negative pressure sucking air pipe, the tension spring guide pillar is packed on the tension force pole socket, tension spring is enclosed within on the tension spring guide pillar, and tension rail is installed on the tension force pole socket by the button pawl on the tension force pole socket.Drive a dovetail groove in appropriate location, the negative pressure sucking air pipe back side, do the tension rail base that a bottom and negative pressure sucking air pipe back side dovetail groove cross-sectional sizes are complementary, base is fixed on the negative pressure sucking air pipe by dovetail groove.In order to prevent tight spinning grid ring left and right sides play in motion process, be provided with the rib that exceeds working face at its two ends, and inner chamber is emptied the displacement that tension spring guide pillar when guaranteeing the tension spring compression does not influence tension rail.Simultaneously, because the ingot that tight spinning grid ring girth difference is brought is poor, tension rail adopts the pattern of one on every ingot in order to reduce.

Compare with the tensioning apparatus of existing tight spinning grid ring, good effect of the present utility model is: reduced the weaving of tight spinning grid ring, back finishing technique requirement, owing to adopt the tension rail pattern of one on every ingot, the girth coherence request of grid ring is reduced greatly; The tension rail self-regulation ability improves greatly, and tension spring adopts stage clip, and wherein stage clip designs according to grid ring self character and kinematic parameter thereof, thereby has avoided because the fluctuation of tension force causes stagnant of grid ring operation and skidding.

The specific embodiment

Be described further below in conjunction with the embodiment of accompanying drawing this utility model.

Among Fig. 1, closely spinning grid ring 4 is enclosed within on the negative pressure sucking air pipe 7, relies on the frictional force of delivery roller 1 to rotate.The power of delivery roller 1 is provided by front roller 3 by delivery roller power drive mechanism 2, and front roller 3 and tight spinning grid ring 6 are tangent but its motion is not exerted an influence, and delivery roller power drive mechanism 2 is generally gear drive or tape handler.Closely the running stability of spinning grid ring 6 is determined by tensioner, overtension or too smallly can occur then that the grid ring motion is made a pause, skidding takes place, and this will bring very burden to normal spinning.The tensioner structure comprises tension rail 4, tension force pole socket 5, tension spring 8 and tension spring guide pillar 9 as shown in Figure 2.Wherein, tension spring guide pillar 9 is fixed on the tension force pole socket 5, and tension spring 8 is enclosed within on the tension spring guide pillar 9, prevents that its elastic force direction when work from changing and influencing the tension force effect, and tension rail 4 is installed on the tension force pole socket 5 by the clasp at tension force pole socket 5 two ends.The mentioned strain device is installed in the dovetail groove of negative pressure sucking air pipe 7 rear portions and its size coupling by the trapezoid cross section of tension force pole socket 5 bottoms.When tight spinning grid ring 6 is installed, only need tension rail 4 is depressed, make tension spring 8 be compressive state and get final product.As shown in Figure 3, one on the every ingot of this tensioner, guarantee respectively each tight spinning grid ring can both be under normal condition actively stable operation, thereby guarantee the yarn quality convergence unanimity of every ingot, the ingot that is lowered into yarn quality greatly is poor.
