Description

Linear drum lifting mechanism of direct twisting machine

Technical Field

The application relates to the technical field of textile equipment, in particular to a linear drum lifting mechanism of a direct twisting machine.

Background

Under the great trend of continuous pursuing high-efficiency and high-quality production in the textile industry, the continuity and fluency of the whole production process are more and more critical. As the core equipment of yarn production, after the straight twisting machine finishes the production of the wire barrel, the transmission link of the wire barrel directly influences the detection of the subsequent finished product and the whole production period. The market demand for yarn continues to rise, requiring both a substantial increase in yield and setting stringent standards for product quality. Therefore, how to efficiently and accurately convey the bobbins produced by the direct twisting machine to the detection process becomes a key for ensuring stable product quality and improving production efficiency.

Currently, in the production line of a direct twisting machine, a mechanical arm is generally adopted to realize the transfer of a bobbin. In particular, common methods include grabbing the wire drum using a single or multi-arm robot and placing it onto a conveyor belt. In addition, some plants use clamps driven by pneumatic or hydraulic systems to assist in the handling of the bobbins. Although these methods can basically meet the transmission requirement of the wire reel, there are some disadvantages in practical application. For example, the problem of speed mismatch of the robot and the clamp during rapid continuous operation tends to result in backlog of the bobbins at the exit of the straight twisting machine, creating a production bottleneck. Even if the speed of the manipulator catches up with the speed of the straight twisting machine for producing the bobbin, the bobbin placed on the conveying table of the next procedure is easy to tip over due to inertia, even roll off the conveying table, and the transmission efficiency and the working efficiency of the subsequent detection procedure are seriously affected.

However, existing manipulators and jigs are prone to speed mismatch problems during rapid continuous operation. When the straight twisting machine rapidly produces the wire barrel, the slow operation of the manipulator can cause the wire barrel to be backlogged at the outlet of the straight twisting machine, so that the production bottleneck is formed. Even if the speed of the manipulator catches up with the speed of the straight twisting machine for producing the bobbin, the bobbin placed on the conveying table of the next procedure is easy to tip over due to inertia, even roll off the conveying table, and the transmission efficiency and the working efficiency of the subsequent detection procedure are seriously affected. Meanwhile, the frequent rotation of the manipulator can also cause the problems of offset, inclination and the like when the wire barrel reaches the detection position, so that the probability of false detection and missing detection is increased, and the reliability of the product quality is reduced.
