Description

Spun silk strip drafting waste silk prevention device

Technical Field

The utility model belongs to the technical field of spun silk processing technique and specifically relates to a spun silk strip draft prevents useless silk device.

Background

In the prior art, silk yarns are easy to wind on a drafting roller in the process of drafting the spun silk yarns, waste silk is finally formed, normal operation of equipment is influenced, waste of the spun silk yarns is caused, and production and processing cost is high.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the technical problem that the waste silk device is prevented in the spun silk strip draft can avoid winding part of silk threads on the guide roller in the drafting process to produce waste silk.

In order to achieve the above object, the utility model provides a silk strip draft prevents useless silk device, including the frame, the interval is provided with three at least drafting mechanisms of group in the frame, and all drafting mechanisms's structure is the same, and drafting mechanism's structure is: the roller mechanism comprises a first roller, a second roller and a third roller, wherein the first roller is positioned on a rack above the second roller and the third roller, the axis of the first roller is positioned above the axis between the second roller and the third roller, and the gap between the first roller and the second roller is equal to the gap between the first roller and the third roller; the first roller is a rubber roller, inner grooves are uniformly arranged on the surfaces of the second roller and the third roller at intervals, and the length direction of the inner grooves is arranged along the axial direction of the second roller and the third roller; be provided with one in the frame of No. two rollers and No. three roller below and prevent useless silk frame, prevent that useless silk frame is a wooden plate body, the length direction of wooden plate body sets up along the axial of No. two rollers, is provided with two cross sections along length direction at the upper surface of wooden plate body and prevents useless silk groove for the arc, two prevent that useless silk groove corresponds with No. two rollers, No. three rollers respectively, prevent that useless silk groove is the same with the clearance between No. two rollers, No. three rollers that correspond.

According to the technical scheme, the spun silk strips are drafted by utilizing the speed difference of the three groups of drafting mechanisms. And the positions of the second roller and the third roller are arranged, so that the contact area between the silk strips and the first roller is larger, and the drafting effect is better. In addition, the surfaces of the second roller and the third roller are provided with axial inner grooves, and spun silk strips can be better drafted by the inner grooves. The setting of the wooden plate body of bottom to set up on wooden plate body and prevent useless silk groove, the part of No. two rollers, No. three rollers be located and prevent useless silk inslot portion, when the silk thread winding is at No. two rollers or No. three rollers, because No. two rollers, No. three rollers and prevent that the clearance between the lateral wall in useless silk groove is less, so the silk waste can with prevent producing the friction between the useless silk groove to one side propelling movement, so it can not twine on No. two rollers or No. three rollers. Meanwhile, after a certain amount of waste silk is accumulated on one side of the waste silk prevention groove, the waste silk can contact with the normally conveyed spun silk strips and finally enters the spun silk strips to be re-drafted, so that extra waste silk cannot be generated, the service performance of the equipment is ensured, and the stability is high.

The lower extreme interval of wooden plate body be provided with a plurality of rubber connecting rods, rubber connecting rod's lower extreme and frame between fixed connection. Above-mentioned structure can make wooden plate body can produce certain vibration amplitude under rubber connecting rod's effect, thereby make prevent waste silk groove and No. two rollers on the wooden plate body, clearance between No. three rollers changes, its lateral wall and No. two rollers that prevent waste silk groove at some moment, No. three rollers are close, can be better to the winding at No. two rollers, the silk thread on No. three rollers limits, it is more around avoiding it, with the silk thread separation in the tip of preventing waste silk groove, waste silk effect is prevented in better realization.

The utility model provides a silk strip draft prevents silk waste device, it is through reasonable structural design, and the realization that can be better is getting rid of the waste water of coiling on No. two rollers, No. three rollers as early as possible and is merging silk strip again to silk strip draft in-process, reduces ultimate silk waste and produces to lifting efficiency, draft quality etc..
