Tube-failing preventing device for doffing tubes of ring spinning machine

Abstract

The invention relates to a tube-failing preventing device for doffing tubes of a ring spinning machine. The tube-failing preventing device comprises a full tube storehouse, a right limiting plate for preventing tube-failing, a left limiting plate for preventing tube-failing, a first bracket, a second bracket, a photoelectric switch, a reflecting plate, a steel belt and a convex plate, wherein the two sides of the doffing tube outlet of the full tube storehouse are provided with the first bracket and the second bracket, the right limiting plate for preventing tube-failing is fixed on the first bracket, and the left limiting plate for preventing tube-failing is fixed on the second bracket; the right limiting plate for preventing tube-failing and the left limiting plate for preventing tube-failing are opposite to form a cop tube limiting area with the width as the same as that of the doffing tube outlet of the full tube storehouse; the photoelectric switch is fixed on the first bracket, and the reflecting plate is fixed on the second bracket; the installment positions of the photoelectric switch and the reflecting plate are opposite to form a reflecting circuit for detecting the mutual feedback of light paths, and the convex plate is fixed on the steel belt. The tube-failing preventing device for the doffing tubes of the ring spinning machine greatly reduces the steel belt and plastic part damage caused by continue walking of the steel belt after cop-tube failing, and thus reduces the maintenance cost of the collecting failing of the steel belt.

Description

technical field [0001] The invention belongs to a component of a textile machine, and in particular relates to a collective doffing tube anti-falling tube device of a ring spinning frame. Background technique [0002] There are generally two operating modes for the collective doffing cams of the existing ring spinning frame: the cylinder drives the cams in the steel plate cam guide rail to move; the motor drives the steel belt to guide the cams to run. The first operation mode relies on the push and pull of the cylinder to move the convex disc. The steel guide rail is relatively simple in user management and maintenance. When the colony down tube fails, only the convex disc or the bobbin is often damaged, and the steel plate is less likely to be damaged. However, the requirements for the material and size of the convex plate are high, and the convex plate is relatively easy to wear. Simultaneously, the running speed of the cam is greatly restricted, which cannot meet the re...

Problems solved by technology

However, due to the steel belt itself, it is easier to deform than the steel plate when it receives an external force, which has higher requirements for the user. Once the colony drop tube fails, it is easy to damage the plastic parts and steel belt on the steel belt, which virtually increases the colony. maintenance cost
