Electromagnetic drying device for yarn sizing machine

Abstract

The invention discloses an electromagnetic drying device for a yarn sizing machine, and relates to the field of yarn sizing machines. The machine comprises two supporting legs, a drying roller, an iron rod, an induction coil, a plurality of supporting plates and a pushing part; the two supporting legs are fixed on the two sides of the yarn sizing machine correspondingly; the drying roller is internally provided with an inner cavity, the iron rod is located in the inner cavity, the drying roller is located between the supporting legs, the two ends of the drying roller are rotationally connectedwith the corresponding supporting legs, and the two ends of the iron rod are fixed to the end face of the inner cavity; the induction coil sleeves the iron rod, and the connecting end of the induction coil is connected with a power supply after penetrating through a through hole formed in the central axis of the drying roller; a supporting groove for placing the plurality of supporting plates areformed in the side surface of the drying roller; and the pushing part is in power connection with the plurality of supporting plates. According to the machine, when yarn sensitive to temperature aredried or yarn thin in diameter are dried, the supporting plates are moved to the exterior of the supporting groove through the pushing part, the yarn is supported by the supporting plates, a certain distance is reserved between the yarn and the drying roller, and in this way, the drying temperature can be reduced, and the situations that due to the fact that the temperature of the drying roller istoo high, the yarn is scalded, and the quality of the yarn is reduced are avoided.

Description

technical field [0001] The invention relates to the field of sizing machines, in particular to an electromagnetic drying device for a sizing machine. Background technique [0002] The sizing machine can warp the silk on the creel to make a warp beam, and then sizing and drying it to make a sizing shaft. At present, the commonly used drying method is to directly blow high-temperature hot air into the drying room. Now there is also the use of electromagnetism to generate eddy currents to heat the internal iron ring for drying treatment. In this way, the drying efficiency is high. And it dries evenly, so it is more and more valued by manufacturers. [0003] The applicant found that: because some silk threads are sensitive to temperature, the thickness of some silk threads may be different, so the temperature requirements for drying will also be different. In the prior art, the silk thread will be close to the iron ring during the drying process, so For silk thread that is sen...
