A device with synchronous line feed and reminder for canvas production

Abstract

The invention relates to the technical field of canvas production equipment and discloses synchronous thread feeding equipment with a reminding function for canvas production. The equipment comprisesa yarn support, a driving shaft is connected to the upper end of the yarn support, and a first permanent magnet is connected to the lower end of a yarn bobbin; a second permanent magnet is connected to the lower end of the yarn support, a first capacitor layer is connected to the middle of the driving shaft, and a second capacitor layer is connected to the middle of the yarn bobbin; an arc rod isconnected to the upper end of a button, a metal ball is connected to the right end of a slide rod, a fixing rack is connected to the right side of the metal ball, and a metal sheet is connected to thelower portion of the metal ball. A rotation shaft drives the yarn bobbin to rotate, the second permanent magnet pushes the first permanent magnet to move upwards, the voltage between the first capacitor layer and the second capacitor layer is reduced, the voltage of the two ends of the driving shaft is increased, since the diameter of the yarn added to the yarn bobbin is reduced, the linear speedis lowered, the problem of thread breaking during canvas production is solved accordingly, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of canvas production equipment, in particular to an equipment with synchronous line feed and reminder for canvas production. Background technique [0002] Canvas is a thick and strong plain cloth of different weights woven from hemp or cotton yarn, used to make tents, camp beds, clothes, shoes, etc. It is named after it was originally used for sails. Canvas is usually divided into two categories: coarse canvas and fine canvas: coarse canvas has good waterproof performance, and is used for covering automobiles and open warehouses and setting up tents in the wild; fine canvas is used for making labor Protective clothing and its supplies. [0003] The weaving machine is an important equipment for the production of canvas, but the current wire inlet device of the weaving machine still adopts the traditional wire inlet method, that is, the hollow shaft is sleeved on the support column, and the raw material is tr...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device with synchronous thread feed and reminder for canvas production, which has the advantages of automatically compensating the yarn feed speed, reminding to replace the yarn, reducing thread breakage and improving work efficiency. It solves the problems of not being able to automatically compensate the yarn feed speed, not being able to remind to change the yarn, and being easy to break, resulting in low work efficiency
