Single ingot combined automatic stop arrangement of composite twisting machine

Abstract

The invention relates to a full automatic control device of textile machinery, which solves the technical problem of leading a spindle in every twisting unit equipped with the full automatic control device to have the function of automatic stop of short yarn and full tube as well as the characteristics of rapid response, sensitive operation, accurate computation, structural durability and low cost. A composite twisting machine single spindle assembly automatic stop device also comprises a broken wire detecting rod articulated on a stander, a trigger rod positioned under the broken wire detecting rod, a piece of electromagnet used for absorbing the trigger rod and driving the trigger rod to move downwards, a winding roller clutch and an electronic detecting head installed on the clutch; a loop at one end of the broken wire detecting rod is used for being passed through by yarn, and presses the trigger rod arranged under the loop to move downwards together when the yarn is broken; the electronic detecting head send out electrical signals when the length of the twisted yarn reaches the preset standard; once receiving the electrical signals, the electromagnet immediately absorbs the trigger rod and drives the trigger rod to move downwards, and the winding roller clutch is further triggered to act and do stop operation at once.

Description

technical field [0001] The invention relates to a fully automatic control device for a textile machine, in particular to a control device for automatically stopping when the thread is broken and when the tube is full, equipped for each spindle on a compound twisting machine. Background technique [0002] The working principle of the twisting unit of the conventional compound twisting machine is as follows: Figure 7 As shown: the power output by the motor is transmitted to the driving gear in each twisting unit, and the driving gear meshes with the big roller gear coaxial with the big roller to make the big roller rotate, thus driving the combined silk yarn S to move downward (from The thread S1 unwound from the 2 or 3 upper spindles 1 respectively passes through the guide ring 40 and merges into a thread S, and then goes around the large roller 20 and the small roller 19 for several turns at the same time, and is drawn by the rotating large roller 20 Moving down), the lower...

AI Technical Summary

Problems solved by technology

When a broken wire fault occurs, the operator needs to find out and deal with it in time (start the manual brake mechanism to stop the spindle from rotating and reconnect the broken wire), otherwise it will easily cause the yarn to wrap around the roller and break the surrounding yarn, resulting in waste of raw materials and yarn failure. A large amount of oil-stained yarn is produced on the surface of the tube; this requires the operator to inspect continuously, which not only requires a lot of work, but also requires a lot of labor, large material consumption, low product quality, and low production efficiency.

In addition, the length of the twisted yarn produced by each spindle on this compound twisting machine is not uniform, which cannot meet the market demand
