Combing machine coiler bell mouth

Abstract

The invention relates to a coiling comber of a bellmouthing, the shape of the invention is that a section of bent pipe is arranged on a diamond-shaped flange plate, the offset distance between the center of the bent pipe and the center of the flange plate is f=17mm-19mm, the top portion of the bent pipe is provided with a conical straight pipe whose length is a=9mm-11mm and taper is 1:20, the diameter of the larger end of the conical straight pipe is b=phi36mm-phi38mm, the inclination angle of the conical straight pipe is a=18degrees-22degrees, the lower portion of the conical straight pipe isprovided with a conical bent pipe whose taper is 1:20, the conical bent pipe takes circular arc c=R49mm-R50mm as central line, the offset distance of the central point of the central line and the center of the flange plate is e=34mm-38mm, the length of the conical bent pipe is the length between the flange plate as 0 degree and beta=65degrees-75degrees, a gap is opened on the one lateral of the center of the flange plate on the bottom portion of the bent pipe, the gap is smoothly transited with the inner lateral face of the bent pipe, wherein the offset distance of the center of the gap and the center of the flange plate is k=5mm-7mm. When the comber is operated at a high speed, the invention can lead combing sliver smooth, flat and no winding cotton, and full-automatic strip break function of auto position can be reliably realized when changing barrel.

Description

technical field [0001] The invention belongs to a part of a combing machine, and in particular relates to a coiling bell of a combing machine. Background technique [0002] At present, the internal shape of the coiling horn of the combing machine is an equal-diameter bend. When the cotton sliver is coiled after it comes out, there is no good smooth transition surface because the contact between the equal-diameter bend and the cotton sliver is at a 90° angle. , when the comber runs at a high speed, it scratches the sliver at the exit, causing the sliver to hang, which seriously affects the forming quality of the combed sliver; the contact between the equal-diameter bend and the sliver is 90 ° angle, forming a certain longitudinal extrusion on the sliver, it is difficult to break the sliver smoothly when positioning the car to change the can, so that the automatic sliver breaking function cannot be well completed. Contents of the invention [0003] The technical problem to ...

AI Technical Summary

Problems solved by technology

It solves the problem that the combed sliver is scratched and scratched during coiling, and cannot be broken smoothly during positioning and parking, so that the quality of sliver forming has been greatly improved, and it can be realized when the positioning parking is changed. Automatic strip breaking function
