[0014] The present invention provides a grabbing device for a cotton yarn stacking machine, which has the following beneficial effects: (1) The invention, when the square plate moves forward, the square plate will contact with the cotton yarn box. When the square plate continues to move forward, the square plate will drive the cotton yarn box to move upward. When the cotton yarn box moves upward, the cotton yarn box will be out of contact with the shelf, which can effectively reduce the friction between the cotton yarn box and the shelf, reduce the wear of the shelf and the cotton yarn box, and when the base of the shelf is unstable, directly removing the stack may cause the center of gravity of the shelf to be unstable, thereby causing collapse.

When the push plate 1 continues to move to the right, the spring 3 will contract. At this time, the cotton yarn box will be fixed, which can effectively prevent the cotton yarn box from shaking and shifting during the movement, which will cause the position of the cotton yarn box to deviate. When there is a larger cotton yarn box, the spring 3 will contract. At this time, the larger the cotton yarn box is, the more firmly the cotton yarn box is fixed, which can prevent the cotton yarn box from falling due to the unstable center of gravity.

[0016] (3) In this invention, the lubricating oil in the lubrication box will flow into the oil outlet pipe, and the lubricating oil in the oil outlet pipe will squeeze open the baffle. At this time, the lubricating oil will flow to the position of the slider and the spiral rod, which can effectively prevent the spiral rod and the slider from rubbing for a long time and causing jamming, thereby affecting the grasping efficiency of the grasping device. When the oil outlet pipe rotates, the area to which the lubricating oil flows will increase accordingly, which can achieve better lubrication effect on the slider and the spiral rod, and can also reduce the temperature generated by the friction between the spiral rod and the slider.
