Double-side feeding and double-side exhausting upper cotton box device

Abstract

The invention belongs to the technical field of textile machinery manufacturing, and relates to improvement of a blowing-carding cotton feeding box, in particular to a double-side feeding and double-side exhausting upper cotton box device. The device comprises an upper cotton box, a front carding needle plate, a rear carding needle plate and a mesh plate; the front carding needle plate and the rear carding needle plate are arranged on the lower side of the upper cotton box; the mesh plate is arranged on the lower side of the rear carding needle plate; a fan cover is arranged on the outer sides of the front carding needle plate, the rear carding needle plate and the mesh plate; and a front exhaust pipe and a rear exhaust pipe are arranged on the fan cover. The upper cotton box comprises a left fiber conveying pipe and a right fiber conveying pipe, and left and right fiber guide plates in arc shapes are arranged between the left fiber conveying pipe and the right fiber conveying pipe. According to the invention, air entering the upper cotton box can be discharged smoothly, the problems that air flow of the upper cotton box is whirled and fibers cannot fall down are solved, smooth cotton dropping of the upper cotton box is ensured, the problem of distribution non-uniformity of fiber feeding in the breadth direction is effectively solved, and the uniformity of cotton dropping is ensured.

Description

technical field [0001] The invention belongs to the technical field of textile machinery manufacturing, and relates to the improvement of a blowing-carding-feeding cotton box, in particular to a cotton box device with double-side feeding and double-side air exhausting. Background technique [0002] The blowing-carding-feeding device is used as the connecting device between the carding machine and the blowing unit to provide continuous and uniform mat cotton for the carding machine and realize the continuous cleaning and carding process. Therefore, the operating efficiency of the cotton feeding box and the quality of the cotton feast directly affect the production index of the carding machine. There are many types of blowing and carding feeding boxes, and in the field of cotton spinning with a width of ≤1.5 meters, the difference is not obvious; but in the field of cotton spinning and non-woven fabrics with a width of ≥2.5 meters, it is common that the fiber feeding is not sm...

AI Technical Summary

Problems solved by technology

There are many types of blowing and carding feeding boxes. In the cotton spinning field with a width of ≤1.5 meters, the difference is not obvious; Problems such as uneven distribution of feeding and output fibers in terms of width not only reduce the operating efficiency of the equipment, but also affect the uniformity of the mat, resulting in fluctuations in the production index of the carding machine
