Abstract

The invention provides a safety belt woven silk yarn winding roll shaft, and relates to the field of safety belt woven silk yarn winding equipment. The safety belt woven silk yarn winding roll shaft comprises a roller body, a center shaft, an adjusting nut and a spring, the roller body is moveably arranged on the center shaft in a sleeved mode, the adjusting nut is mounted on the outer side of the center shaft, and the spring is mounted between the adjusting nut and the roller body. Anti-skid elastic pieces are evenly mounted on the surface around the roller body, each anti-skid elastic piece is a rectangular steel sheet and is clamped on the surface of the roller body through a clamping groove, in the mounting process, the clamping grooves are shorter than the anti-skid elastic pieces, and therefore the middles of the anti-skid elastic pieces are protruded and the elastic pieces have certain telescopic elastic force after being mounted. The safety belt woven silk yarn winding roll shaft is simple in structure, stable to sleeve, convenient to use, obvious in effect, and capable of preventing rotation sliding, conducting fine adjusting on rotating speed, and improving the woven quality and the toughness of a safety belt.

Description

A kind of safety belt braided silk coiling roll shaft

Technical field:

The present invention relates to safety belt braided silk spooling equipment field, be specifically related to a kind of safety belt braided silk coiling roll shaft.

Background technology:

Along with the use of the various vehicle of socioeconomic development is more and more frequent, but along with the traffic accidents that the raising of the frequency of utilization of the various vehicle is caused by the vehicle is also more and more, the requirements for quality of the safety belt therefore configuring on the vehicle is also in raising gradually, and the enterprise of the various safety belts of current domestic professional production is not a lot, therefore in the performance of safety belt, on quality and safety factor, all have much room for improvement, wherein having a commonplace problem is exactly in braiding safety belt, because the silk thread of braiding has a lot of bars, therefore need neat silk thread being placed on a fixing support, then to carry out unwrapping wire, could carry out orderly braiding by convenient braider like this, but at present a lot of manufacturers are all that the problem there will be is exactly the situation that coil drops that often occurs in the process at unwrapping wire in braiding, major cause is because coil ceaselessly rotates in unwrapping wire, place and do not arrange the facility that coil drops on the stationary roll of coil, and can not the rotative speed of coil be controlled and be regulated and in weaving, often there will be so the untight phenomenon of braiding, affect to a great extent the weaving quality of the weave effect of safety belt.

Summary of the invention:

Technical matters to be solved by this invention is to provide a kind of simple in structure, suit to stablize, prevent rotational slide, can carry out to rotative speed the safety belt braided silk coiling roll shaft of minor adjustments.

Technical matters to be solved by this invention adopts following technical scheme to realize:

A kind of safety belt braided silk coiling roll shaft, comprise roll body, center shaft, setting nut and spring, described roll body movable set is on center shaft, outside at center shaft is provided with setting nut, between setting nut and roll body, spring is installed, the surrounded surface of described roll body is evenly provided with anti-skidding shell fragment, described anti-skidding shell fragment is rectangular steel disc is installed on roll body surface by draw-in groove, the short 1cm of length of the anti-skidding shell fragment of Length Ratio of draw-in groove in installing, will make the intermediate projections of anti-skidding shell fragment and have certain stretching elasticity after installing like this.

When adopting this safety belt braided silk winding roller, first wire coil is sleeved on roll body, in the time that wire coil is clamped by anti-skidding shell fragment by spring fitting on the center shaft in axis body outside, then setting nut is screwed tight, wire coil is just by firm being fixed on roll body like this, in the time that wire coil is carried out unwrapping wire, roll body can be rotated at center shaft, and anti-skidding shell fragment can prevent between coil and roll body being subjected to displacement, ensure the stable of unwrapping wire, in the time need to carrying out trickle adjusting to the speed of unwrapping wire, can screw setting nut, the spring being arranged in the time that setting nut screws between setting nut and roll body can be by jam-packed, then spring can pass to pressure of roll body, the rotative speed that so just can reduce roll body reaches with this adjusting that reduces payingoff speed and silk thread elasticity, when the payingoff speed of silk thread reduce and elasticity raising after be just of value to the tight ness rating of the braiding that improves safety belt, there is a very large lifting for the tough and tensile degree of safety belt like this.

The invention has the beneficial effects as follows: simple in structure, suit is stable, easy to use, successful can prevent rotational slide, can carry out minor adjustments and can improve the toughness of weaving quality and the safety belt of safety belt rotative speed.

Brief description of the drawings:

Fig. 1 is structural representation of the present invention;

Wherein: 1-roll body; 2-center shaft; The anti-skidding shell fragment of 3-; 4-setting nut; 5-spring.

Detailed description of the invention:

For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.

As shown in Figure 1, a kind of safety belt braided silk coiling roll shaft, comprise roll body 1, center shaft 2, setting nut 4 and spring 5, described roll body 2 movable sets are on center shaft 1, in the outside of center shaft 1, setting nut 4 is installed, between setting nut 4 and roll body 2, spring 5 is installed, the surrounded surface of described roll body 1 is evenly provided with anti-skidding shell fragment 3, described anti-skidding shell fragment 3 is rectangular steel disc is installed on roll body 1 surface by draw-in groove, in installing, the length of draw-in groove is less than the length of anti-skidding shell fragment 3, after installing like this, will make the intermediate projections of anti-skidding shell fragment 3 and there is certain stretching elasticity.

When adopting this safety belt braided silk winding roller, first wire coil is sleeved on roll body 1, in the time that being clamped by anti-skidding shell fragment 3, wire coil spring 5 is arranged on the center shaft 2 in axis body 1 outside, then setting nut 4 is screwed tight, wire coil is just by firm being fixed on roll body 1 like this, in the time that wire coil is carried out unwrapping wire, roll body 1 can be rotated at center shaft 2, and anti-skidding shell fragment 3 can prevent between coil and roll body 1 being subjected to displacement, ensure the stable of unwrapping wire, in the time need to carrying out trickle adjusting to the speed of unwrapping wire, can screw setting nut 4, the spring 5 being arranged in the time that setting nut 4 screws between setting nut 4 and roll body 1 can be by jam-packed, then spring 5 can pass to 1 one pressure of roll body, the rotative speed that so just can reduce roll body 1 reaches with this adjusting that reduces payingoff speed and silk thread elasticity, when the payingoff speed of silk thread reduce and elasticity raising after be just of value to the tight ness rating of the braiding that improves safety belt, there is a very large lifting for the tough and tensile degree of safety belt like this.
