AI Technical Summary

Technical Problem

The downward distance of the cotton grabbing head in traditional cotton grabbing machines cannot be adjusted in real time according to the thickness of cotton in the cotton bin, resulting in improper tearing force, which may cause cotton fibers to break or fail to output cotton fully.

Method used

An adaptive lifting and lowering control mechanism for the cotton gripper head was designed. The mechanism uses a pressure sensor and a detection roller to detect the pressure of the cotton layer in real time, and adjusts the extension length of the support by spring and screw to achieve adaptive lowering adjustment of the cotton gripper head.

Benefits of technology

It achieves adaptive adjustment of the cotton gripping head, ensuring the quality output of cotton and avoiding problems of excessive tearing or insufficient tearing. It is suitable for cotton processing with different tightness.

Abstract

The utility model relates to a bale plucking head self-adaptive lifting regulation and control mechanism which comprises a rack, a support vertically installed on the rack in a sliding mode, a detection roller rotatably installed on the support, a spring arranged between the support and the rack and a pressure sensor. The rack is used for being installed at the bale plucking head of a bale plucker, and the support extends out of the rack under the action of gravity in a normal state. The pressure sensor is arranged on the rack, the spring is arranged between the support and the pressure sensor, the two ends of the spring abut against the support and the pressure sensor respectively, and the detection roller is used for abutting against a cotton layer. The pressure between the pressing roller of the bale plucking head and cotton is synchronously detected through the detection roller, when the pressure is too small, it is indicated that the bale plucking head descends insufficiently and needs to descend continuously, when the pressure is too large, it is indicated that the bale plucking head descends excessively and needs to ascend, and self-adaptive adjustment is achieved through cooperation of the pressure sensor, the detection roller and the spring.
