It is a combination of a two-point supported slender rotating shaft as the main body, used for winding yarn. In the existing doffing, the tail yarn on the yarn tube falls off on the spindle rod when the tube is pulled out, and the tail yarn needs to be torn off by manual tube pulling action, so a bare spindle collective doffing modification head retention device is used;

[0003] To this end, the patent with publication number CN205603753U discloses a device for collective doffing and modification of spinning bare spindles, comprising a winding ring, one end of which is a positioning sleeve sleeved on the spindle disk, and the other end of which is a winding drum; one end of the winding drum is provided with an end face truncated cone connected to the positioning sleeve, the lower end of the bobbin extends into the winding drum and the lower end face of the bobbin contacts the end face truncated cone, and a blade is provided on the other end of the winding drum; the utility model can not only realize the automatic collective doffing of the traditional spinning short machine, but also solve the technical problems of high cost and low efficiency of manual doffing; and the processing and manufacturing cost is low, which is suitable for mass production and processing;

[0004] Although the above-mentioned collective doffing and head retention device for the spun yarn bare spindles solves the technical problems of high cost and low efficiency of manual doffing, the device is easy to cause the bobbin to fall off when in use, making it less applicable when in use. Utility Model Content

[0019] The utility model provides a device for collectively doffing and renovating yarn retaining of bare spindles, which has the advantages that:

[0020] By setting a limited position structure, the limit block is first placed inside the limit groove, and then the clamping groove at the bottom of the bobbin is aligned with the limit block and moved. When the spindle rod rotates, the bobbin and the spindle rod are connected by the limit block to rotate together, so as to achieve the purpose of transmitting power, thereby avoiding the bobbin from falling off, realizing the function of facilitating positioning of the device, and thus improving the applicability of the bare spindle collective doffing transformation head retention device when in use;

[0021] By providing a fixed structure, the bobbin is placed above the spindle rod, and the bobbin is pushed. Under the squeezing action of the bobbin, the reset plate drives the fixing pin to move to the inside of the movable groove. When it moves to the appropriate position, under the elastic force of the reset spring, the reset plate drives the fixing pin to move to the inside of the fixing hole, so that the fixing pin and the bobbin are engaged with each other, thereby fixing the spindle rod and the auxiliary component to each other. Anti-slip bumps are evenly arranged on the outside of the bobbin, and the friction is increased by the anti-slip bumps to facilitate yarn winding. When the spindle rod drives the bobbin to rotate, the yarn is wound around the outside of the bobbin. After winding, excess tail yarn will fall off the base. At this time, the machine moves the bobbin to one side of the spindle rod through the positioning groove, so that the yarn is easily cut by the blade, realizing the function of easy disassembly of the device, thereby improving the convenience of the collective yarn dropping and head retention device for bare spindles when in use.
