AI Technical Summary

Technical Problem

In existing cotton suction devices for spinning machines, the surface area of ​​the filter screen is limited, resulting in a high frequency of cotton removal and affecting the cotton suction efficiency.

Method used

By employing cotton-blocking needles, a cotton-carding mechanism, and a cotton-pressing mechanism, and through the design of the interception chamber and compression chamber, combined with the working principles of the cotton-carding and cotton-pressing mechanisms, the fibers can slide off on their own and be squeezed and stored, reducing the space occupied by the fibers and improving the cotton suction efficiency.

Benefits of technology

It reduces the frequency of cotton removal, improves cotton absorption efficiency, and facilitates fiber extraction and reduces the risk of fiber scattering by twisting the fibers into strips.

Abstract

The application relates to a cotton suction device which comprises a shell, an air inlet pipe, an air outlet pipe and a cotton blocking plate. The inside of the shell is provided with an interception cavity and a compression cavity which are communicated with each other, and the surface of the shell is provided with a discharge port which is communicated with the compression cavity. The cotton blocking plate is installed in the interception cavity and located between the air inlet pipe and the air outlet pipe. The surface of the cotton blocking plate is connected with a plurality of cotton blocking needles which are arranged at intervals to form a channel for airflow and to block fibers. The shell is provided with a cotton carding mechanism and a cotton pressing mechanism. The cotton carding mechanism is used for carding the fibers on the side of the cotton blocking needles to the compression cavity. The cotton pressing mechanism is used for extruding the fibers in the compression cavity. The cotton pressing mechanism comprises a moving part and a contact part. When the fibers are driven to the interception cavity by the negative pressure airflow, the contact part blocks the communication between the interception cavity and the compression cavity. When the cotton pressing mechanism is started, the moving part drives the contact part to move, and the interception cavity is communicated with the compression cavity. The application has the effects of reducing the cotton picking frequency and improving the cotton suction efficiency of the cotton suction device of a spinning machine.
