Integral doffing modified tailing device of spinning polished rod spindle

Abstract

The invention discloses an integral doffing modified tailing device of a spinning polished rod spindle. The integral doffing modified tailing device comprises a yarn winding loop. A positioning sleeve which sleeves a spindle disc is arranged at one end of the yarn winding loop, and a yarn winding drum is arranged at the other end of the yarn winding loop; an end-surface circular truncated cone which is connected with the positioning sleeve is arranged at one end of the yarn winding drum, the lower end of a spool extends into the yarn winding drum, the end surface of the lower end of the spool is in contact with the end-surface circular truncated cone, and blades are arranged at the other end of the yarn winding drum. The integral doffing modified tailing device has the advantages that automatic integral doffing of the traditional spinning chopping machine can be implemented, and accordingly technical problems of high cost and low efficiency of manual doffing modes can be solved; the integral doffing modified tailing device is low in processing and manufacturing cost and suitable for production and processing on a large scale.

Description

technical field [0001] The invention relates to the field of spinning machinery, in particular to a collective doffing and end retention device for polished rod spindles of spun yarns. Background technique [0002] Such as Figure 4 As shown, there is no doffing head retention device on the spun smooth rod spindle in the prior art, and manual doffing is generally adopted manually. When doffing and pulling out, the tail yarn on the bobbin falls off several times and is wound on the spindle bar, and the tail yarn is torn off by manual pulling action. When the empty bobbin is inserted, the empty tube presses the tail yarn remaining on the spindle bar. When the spindle is started, the bobbin is driven to rotate, and the yarn count is rewound on the bobbin to complete the end-retaining process. The manual doffing method not only consumes a lot of labor costs, but also has low efficiency. [0003] With the development of spinning technology and the rising labor cost of textile e...

Problems solved by technology

However, there are still a large number of old-fashioned short spinning machines equipped with polished rod spindles in textile mills, which are far from reaching their service life. Replacement will not only increase costs, but also cause waste of resources. Therefore, it becomes difficult to transform traditional short spinning machines into automatic collective doffing Very necessary, but there is no effective improvement scheme in the prior art
