Start-stop control method of blowing and suction trolley of spinning machine

Abstract

The invention relates to a start-stop control method of a blowing and suction trolley of a spinning machine. The method comprises the steps: firstly, a blowing and suction switch is additionally arranged on a control panel on a motor case of the spinning machine; a support frame is arranged on the spinning machine body along the length direction; a rail for the sliding of the blowing and suction trolley is arranged on the support frame; blowing and suction pipelines are respectively arranged at two sides of the blowing and suction trolley; secondly, the blowing and suction switch on the motor case of the spinning machine is started and the blowing and suction trolley during moving blows waste yarns and fluffs on the ground into the blowing and suction pipelines by using the blowing and suction pipelines; thirdly, a proximity switch and an infrared detection delay switch are additionally arranged at the tail of the blowing and suction trolley and a touch switch is additionally arranged on the blowing and suction trolley; when the blowing and suction trolley moves to the tail part, the touch switch contacts with the proximity switch and the blowing and suction trolley stops moving; after stopping for a certain time, the blowing and suction trolley slides to the head end under the action of the infrared detection delay switch. According to the start-stop control method of the blowing and suction trolley of the spinning machine, the spinning stability of the spinning machine is improved.

Description

technical field [0001] The invention belongs to the field of spinning frames, and in particular relates to a method for controlling the start and stop of a blowing and suction trolley of the spinning frame. Background technique [0002] The original blowing and suction trolley needs to reciprocate continuously during the spinning process on the track, which is not energy-saving. If the blowing and suction trolley blows the yarn on the spindle for a long time, the yarn is easy to dry and easy to break. Affect the quality of finished yarn, resulting in lower yield. Contents of the invention [0003] The object of the present invention is to provide a method for controlling the start and stop of the blowing and suction trolley of the spinning frame. After adopting the invention, the quality of the finished yarn of the spinning frame is high, the yarn is not easy to be broken, and the finished product rate is high. [0004] The technical scheme adopted by the present invent...
