Improved single-tube yarn feeder with pitch adjusting function

Abstract

The invention relates to an improved single-tube yarn feeder with a pitch adjusting function. A yarn guide rod assembly is installed on a thread inlet yarn guide rod mounting seat at the upper left corner of the top of a single-tube seat. A motor shaft hole is formed in the middle of the upper portion of the single-tube seat. A motor is installed on the single-tube seat. A driving belt wheel is fixedly installed on a motor output shaft. A roller mounting seat is arranged on the lower left portion of the motor shaft hole. The end of a roller mandrel is installed in the roller mounting seat in a supported mode and can move. The roller mandrel is sleeved with a roller drum, and the roller drum can rotate freely. The roller drum is in transmission connection with the driving belt wheel through a transmission belt. Pitch adjusting connecting plates are arranged at the two ends of a roller correspondingly. The small-head end of each pitch adjusting connecting plate is connected to the yarn guide rod assembly in a hinged mode. The big-head end of each pitch adjusting connecting plate is provided with an open mounting groove. The roller mandrel is installed in the open mounting grooves in an embedded mode. A yarn breaking automatic stop mechanism is installed on a microswitch mounting seat and an automatic stop rod supporting seat on the lower right portion of the motor shaft hole. By the adoption of the improved single-tube yarn feeder, the situation of yarn breaking can be effectively reduced, and the operation safety of the equipment is improved.

Description

technical field [0001] The invention relates to a textile machinery equipment, in particular to an improved single tube yarn feeder with the function of distance adjustment. Background technique [0002] The various mechanical equipment required to process natural fibers or chemical fibers into textiles are collectively referred to as textile machinery. Textile machinery in a broad sense also includes chemical machinery for the production of chemical fibers. Textile machinery is the production means and material basis of the textile industry. Its technical level, quality and manufacturing cost are directly related to the development of the textile industry. [0003] The yarn feeder is an important mechanical equipment in the textile machinery industry, which is used to guide the yarn during the textile process. However, the existing yarn feeder has the disadvantage of not being able to transport the yarn smoothly in actual work, and the output pulling force is unstable, wh...
