Middle school electrostatic dust removing and yarn winding demonstration device

Abstract

The invention discloses a middle school electrostatic dust removing and yarn winding demonstration device. The middle school electrostatic dust removing and yarn winding demonstration device is characterized in that the middle school electrostatic dust removing and yarn winding demonstration device comprises a rack; a rack platform is arranged on the rack; a yarn stranding frame is arranged to one side of the rack; the yarn stranding frame is wound with yarns; the front side of the rack is provided with a front guide device; the guide device includes two parallel guide rollers which are arranged sequentially along a vertical direction; a groove extending along the peripheral wall of the guide roller is formed at the middle of the guide roller; the yarns can pass through a space between the two grooves; two end portions of the guide roller are provided with pressing covers; the pressing covers at the two ends of the same guide roller are symmetrically arranged; the pressing cover is of an ring-shaped horn mouth structure; the outer peripheries of the pressing covers of the upper guide roller are of bent structures; the pressing covers of the lower guide roller are inserted at the pressing covers of the upper guide roller; and the rear end of the front guide device is provide with a spray device and a drying device sequentially. With the middle school electrostatic dust removing and yarn winding demonstration device provided by the technical schemes of the invention adopted, existing theories in books can be utilized. The middle school electrostatic dust removing and yarn winding demonstration device has the advantages of high intuitive performance and simple structure.

Description

technical field [0001] The invention relates to a demonstration device, in particular to a middle school electrostatic dust removal and yarn winding demonstration device. Background technique [0002] Middle school has been exposed to chemistry, especially in the extracurricular learning of chemistry, the printing and dyeing process and printing and dyeing materials have been explained, but after all, the machinery and process in the book are not intuitive, and it is difficult for students to understand. [0003] On the other hand, the generation of static electricity has been mentioned in middle school physics, but the use and purpose of static electricity after generation is not well mentioned, and students are not deeply impressed. [0004] At the same time, the existing electronic rapier looms are used to confirm the pattern and color of yarn-dyed gray fabrics. The weft yarn used has been manually wound on the weft bobbin for a long time, which is time-consuming and labo...

Problems solved by technology

[0002] Middle school has been exposed to chemistry, especially in the extracurricular learning of chemistry, the printing and dyeing process and printing and dyeing materials have been explained, but after all, the machinery and process in the book are not intuitive, and it is difficult for students to understand

[0003] On the other hand, the generation of static electricity has been mentioned in middle school physics, but the use and purpose of static electricity after generation is not well mentioned, and students are not impressed

[0004] At the same time, the existing electronic rapier loom is used to confirm the pattern and color of yarn-dyed gray fabrics. The weft yarn used has been manually wound on the weft bobbin for a long time, which is time-consuming and laborious. Usually, a small sample gray fabric with a size of 10*10cm , the weft yarns used need to be wrapped for about an hour, and 6 weft yarns are required for the most colors, which becomes the bottleneck restricting the speed of yarn-dyed samples
