Reel holder for high speed elastic wire winder

Abstract

This invention provides a bobbin holder of winder for winding elastic thread at high speed, which steadily holds bobbins for winding elastic thread to increase holding tension, rotating speed and production rate. The bobbin holder of winder in accordance with the present invention includes: a coupler, a plurality of bodies and rubber being connected in linear arrangement, one side of the bodies being connected to a motor spindle; a shaft connected to the bodies at another end of the coupler, two ends of its diametrical surface being connected to a plurality of bearings and having a fixed length; a support having an inner diametrical surface joining to the bearings and an outer diametrical surface being secured to the winder; a housing joined to an end of the shaft, and formed with a first space subjecting the support and the shaft to be located at an inside, between the inner diametrical surface of the first space and the outer diametrical surface of the support being connected with bearings, a second space being formed on an opposing direction of the first space; a plurality of rollers, surroudingly connected to the entire diametrical surface of the housing; a plurality of rubbers, surroudingly connected between the rollers; and a cover joined to the housing and an end of the second space for pressing the rollers towards the coupler, or recovering the rollers to their original locations, so as to vary the expanding volume of the rubbers. As such, the diametrical surface of the rollers is able to retain or release the bobbin of the elastic thread.

Description

technical field [0001] The present invention relates to a bobbin holder for a coiler for high-speed coiling of elastic yarn. More specifically, it relates to the ability to stably hold the bobbin for coiling elastic yarn, film, paper, etc., increasing the gripping force and increasing the rotation speed. , A bobbin gripper for a coiler for high-speed coiling of elastic yarn to increase production speed. Background technique [0002] figure 1 A partial sectional view showing a bobbin gripper 100' of a known coiler for high-speed elastic yarn coiling. [0003] As shown in the figure, the bobbin gripper 100' of a known high-speed coiling machine for elastic yarn includes: a coupling 2' coupled to a motor (not shown); a shaft 4' coupled to the aforementioned coupling 2 '; cylinder 6', coupled to the end of the aforementioned shaft 4', has a certain length; cover 8', coupled to the end of the aforementioned cylinder 6'; a plurality of protruding rings 10', coupled to the aforem...

AI Technical Summary

Problems solved by technology

[0008] First, the support structure of the shaft and the cylinder connecting the shaft is very weak because the support point of the cylinder and the shaft is formed only in a single area

[0009] Second, the O-ring with a small surface area is pushed outward or returned to the original position by means of the clamping member, and the bobbin is grasped or released. The lifespan is also short, and the grip is weak, too

[0010] Third, because the shaft and the cylinder are connected together in a straight line, there is a lack of solidity as a whole. Therefore, the natural vibration number of the bobbin holder, that is, the resonance frequency will become smaller. As a result, the critical rotational speed of the bobbin holder and the speed at which the elastic yarn is taken up will slow down

[0011] Fourth, the spool holder is coupled to the motor in the form of 2 links through a coupling, so the amount of vibration impact reduction due to misalignment is reduced, so the rotation characteristics of the spool holder will be weakened
