Technical Field

The invention belongs to the technical field of textile equipment, and particularly relates to a drawing device for gathering, mixing and detecting broken slivers.

Background

The drawing frame is mainly composed of three parts of feeding, drafting and forming winding, and aims to improve the straightness and the separation degree of internal fibers, increase the yarn number and reduce the ration, and is particularly important for the quality of finished yarns. And various cotton slivers can be uniformly mixed and collected, and the difference between the cotton slivers with different qualities is balanced, so that the optimal blending ratio and evenness of the cotton slivers are achieved.

When the existing drawing frame is used for drafting and mixing cotton slivers with various different qualities, the condition that the straightening degree of mixed uneven fibers is not enough or even the cotton slivers are broken can occur, and after the condition occurs, workers can not find fault location in time, so that the working efficiency is reduced, and the later sliver forming quality and the integral working efficiency are seriously influenced.

In view of the above problems, an effective solution and method are urgently needed.

Disclosure of Invention

The invention aims to disclose a drawing device for gathering, mixing and detecting broken slivers, which aims to solve the problems that the extension degree of fibers of various cotton slivers which are not uniformly mixed is not enough and faults cannot be found and positioned in time due to breakage of the cotton slivers.

In order to achieve the purpose, the invention adopts the following technical scheme:

a gather and mix and detect the drawing device of the broken string, gather the device to install in the back rubber roll and its roller and bunch the rubber roll and its roller of the drawing frame, gather the device to include: the device comprises a strip collecting pipe, a photoelectric emitter, a photoelectric receiver and an air suction device, wherein the photoelectric emitter and the receiver are arranged on the strip collecting pipe, the air suction device is sleeved on a collecting opening, one end strip collecting opening of the collecting device draws in the drawn thick strips, and the other end strip collecting opening outputs the mixed fiber strips.

Preferably, the photoelectric emitter and the photoelectric receiver are arranged on two sides of the collecting tube in parallel alignment and are electrically connected, and the photoelectric emitter and the photoelectric receiver are used for sensing and detecting the breakage of the thick strips.

Preferably, the air suction device is provided with a plurality of air suction holes which are uniformly distributed on the periphery of the collecting opening to form conical air flow with a cone angle of 60 degrees, so that certain drafting is generated and negative pressure difference is combined, and the drafted thick slivers can be drawn and collected into the sliver collecting pipe.

Preferably, the rough sliver is pressed by the pressure bar in the drafting zone for stable drafting, so as to avoid changing the drafting path and orientation arrangement of the fibers in the sliver, and then orderly enter the next drafting zone.

Preferably, the bundled thick strips output from the gathering port enter the strip guide pipe under the drafting of the bundling roller and the rubber roller thereof, and then are condensed into strips to be output into the strip barrel.

The roving frame disclosed by the invention is simple in structure and convenient to operate, can be used for enhancing and uniformly mixing various roving strips with different qualities, reducing fiber buckling and hook in a roving body and increasing the straightening degree and the separation degree of fibers, so that the yarn evenness and the quality of the roving are improved, the roving strip breakage condition can be monitored in real time, the fault location can be found in time, and the production efficiency is improved.
