Bobbin and spindle connector

Abstract

The invention discloses a bobbin and spindle connector which comprises a shell, a sleeve, a yarn cutter and a positioning sleeve. A first clamping portion is arranged at the upper end of the sleeve, a second clamping portion is arranged at the lower end of the sleeve and fixed in the shell, the first clamping portion is clamped to the top end of the shell, and the yarn cutter is arranged between the top end of the shell and the first clamping portion and protrudes outwards; the positioning sleeve is arranged in the sleeve through the second clamping portion, an inner hole formed in the upper end of the positioning sleeve serves as a bobbin connection hole, and an inner hole formed in the lower end of the positioning sleeve serves as a spindle connection hole. By applying the bobbin and spindle connector, a bobbin and a spindle are connected, a traditional spindle structure can be remained, the spindle speed is guaranteed, and the advantages of being low in equipment cost and yarn breakage rate are achieved.

Description

technical field [0001] The invention relates to the technical field of spinning machine accessories, in particular to a bobbin spindle connector. Background technique [0002] The ring spinning frame is a kind of commonly used spinning equipment. The roving sliver spun by the roving frame in the previous process is further drafted and twisted into fine yarn, and wound on the yarn mounted on the spindle. On the tube, it is used in the subsequent process (winding); the bobbin and the spindle are connected in a certain form, so that when the spindle rotates at high speed, it will rotate with the bobbin, and at the same time complete the twisting and winding functions. [0003] With the advancement of technology, the spinning frame collective doffing system is often used in the yarn making process to reduce the cost of yarn making, reduce labor intensity and meet the application of advanced fine-bonding technology; while the traditional spinning frame bobbin and spindle In the ...

AI Technical Summary

Problems solved by technology

[0003] With the advancement of technology, the spinning frame collective doffing system is often used in the yarn making process to reduce the cost of yarn making, reduce labor intensity and meet the application of advanced fine-bonding technology; while the traditional spinning frame bobbin and spindle In the connection method, the bobbins are fixed and cannot be pulled out, and this connection method can no longer meet the requirements of collective doffing and collective extubation; in order to meet the requirements of collective doffing and extubation, at present, aluminum casing spindles have been produced, using The bobbin and the spindle are positioned, connected, and rotated synchronously by means of spring tension; the cost of the spindle using the aluminum sleeve is greatly increased, and the addition of the aluminum sleeve increases the moment of inertia of the spindle and the swing of the bobbin Large, increase the vibration of the main machine, limit the spindle speed and increase the yarn breakage rate; if the collective doffing transformation is carried out on the original spinning frame, it is necessary to replace the original (polished rod) spindle with an aluminum casing spindle, so that Retrofit costs are greatly increased

[0004] In summary, the aluminum sheathed spindles used in the prior art have the disadvantages of high equipment cost, limited spindle speed, and high yarn breakage rate
