Description

Technical Field

[0001] The utility model belongs to textile machinery and equipment, in particular to a double-jointed tube grabber which is easy to install on a spinning frame. Background Art

[0002] The pipe grabbers currently available on the market are mainly divided into two types in terms of appearance and structure: single-spindle single-body type and double-spindle duplex type. One is single-spindle single-body type and the other is double-spindle duplex type. Among them, the single-spindle single-body type means that each spindle is an independent pipe grabber, which is fixed to the gas rack through the slot structure of the gas rack and the single fixing screw. It has the advantages of convenient installation and fast positioning. However, because the pipe grabber of this structure is a single-spindle single-body type, the length of the contact surface between it and the gas rack is relatively short, and there is only one fixed point below the pipe grabber connected to the gas rack. During installation, it is easy to cause the axis of the pipe grabber to be not perpendicular to the horizontal plane, thereby causing the pipe grabber to be out of alignment with the horizontal plane. This will have an adverse effect on the subsequent gathering action of the spinning frame; the double-spindle double-connected type designs the tube grabbers of the two spindles as a whole, sharing a common installation body. Although the contact surface length between the single-spindle single-body tube grabber and the air frame is increased, the tube grabber can be installed more accurately, but this type of tube grabber is fixed by six fixing screws and square nuts placed in the air frame. The workload of the staff when installing the tube grabber is large, and when replacing the tube grabber, the tube grabber needs to be installed again. At this time, the six fixing points of the tube grabber need to be aligned with the square nuts placed in the air frame. The operation is difficult and the replacement work efficiency is reduced.
