[0002] While the evolution from single twisting on traditional twisting machines to double twisting on the now-commonly used two-for-one twisting machines has significantly improved production efficiency, it still hasn't met expectations. Consequently, researchers have been developing quadruple twisters. The key to developing quadruple twisters lies in the development of four-twist spindles. While many researchers have previously conducted research on these spindles, their success has yet to be commercialized. The primary reason is that the method for achieving four-for-one twisting is unstable, impacting product quality. Furthermore, while mechanically sound, the twisting process itself is often difficult to implement. Summary of the Invention

[0003] In view of the problem of unstable twisting mode in existing quadruple twisting spindles, the present invention aims to provide a quadruple twisting spindle with a reasonable structure and capable of industrialization in twisting process.

[0004] To this end, the present invention adopts the following technical solution: a four-fold twisting spindle, comprising a lower twisting component and an upper twisting component, characterized in that the upper twisting component comprises an upper spindle shaft, an upper twisting disk and a first spindle pulley, the first spindle pulley is connected with the upper spindle shaft and drives the upper spindle shaft to rotate, the upper twisting disk is fixed to the upper section of the upper spindle shaft, the upper yarn spacer disk is fixed to the top of the upper twisting disk and is fixed by screws to form a whole; the upper spindle shaft, the upper yarn spacer disk and the upper twisting disk are driven to rotate together by the first spindle pulley;

[0005] The lower twisting component includes a lower spindle shaft, a lower twisting disk and a second spindle pulley. The lower spindle shaft is a hollow shaft. The middle section of the upper spindle shaft is installed in the lower spindle shaft through a bearing. The lower section of the upper spindle shaft passes through the lower spindle shaft and is connected to the first spindle pulley. The lower section of the lower spindle shaft is connected to the second spindle pulley. The middle section of the lower spindle shaft is supported by a bearing and installed on the spindle seat. The lower twisting disk is fixed to the upper section of the lower spindle shaft. The lower yarn spacing disk is fixed to the top of the lower twisting disk and fixed by screws to form a whole.

[0006] As a supplement and improvement to the above technical solution, the present invention also includes the following technical features.

[0007] The yarn supply bobbin is installed on the inner side of the yarn storage tank. A magnet is provided on the inner side of the yarn storage tank to attract the external magnet, so that the yarn storage tank and the yarn supply bobbin remain stationary during the operation of the spindle.

[0008] The quadruple twist spindle also includes a lining spindle tensioner. The fixed tube of the lining spindle tensioner is arranged in the central inner hole of the yarn supply bobbin and is connected and cooperated with the upper twisting disk. The lining spindle tensioner can achieve smooth withdrawal and adjust the tension of the balloon during operation.

[0009] The quadruple twist spindle further comprises a yarn guide device located above the yarn supply bobbin.

[0010] The upper end and the lower section of the center hole of the lower spindle shaft are both provided with step grooves, bearings are provided in the step grooves, and the upper spindle shaft is installed on the lower spindle shaft through the bearings.

[0011] The present invention achieves the following beneficial effects: The lower and upper twisting components are driven by separate drive mechanisms, eliminating the need for an intermediate transmission section between the lower and upper twisting components. This achieves the functionality of a four-twist spindle, improving efficiency and reducing energy consumption, thereby lowering production costs. The present invention utilizes practical twisting process design to ensure a stable and reliable twisting process, improve yarn twist quality, and enable industrialization.

[0019] Preferably, the quadruple twist spindle further comprises a yarn guide device located above the yarn supply bobbin 11. The yarn guide device comprises a yarn tube, a shaft sleeve, a yarn guide ring and a yarn guide tube, the upper portion of the yarn guide tube is fixedly mounted on the mounting support of the frame through the fixing seat of its outer sleeve, the upper portion of the shaft sleeve is supported by a bearing and is outer-mounted on the lower portion of the yarn guide tube, the bottom of the yarn guide tube extends into the hollow inner cavity of the shaft sleeve, the yarn guide ring is outer-mounted on the middle portion of the shaft sleeve, the top of the yarn guide ring is a trumpet-shaped opening, and the side surface of the top of the yarn guide ring is provided with a yarn guide port connected to the inner cavity of the shaft sleeve, the yarn tube is supported and mounted on the lower portion of the shaft sleeve through a bearing, the bottom of the yarn tube is provided with a first yarn inlet, the side portion of the lower portion of the yarn tube is provided with a first yarn outlet connected to the first yarn inlet, and the bottom and top of the yarn guide tube serve as a second yarn inlet and a second yarn outlet respectively.

[0020] The upper end and the lower section of the center hole of the lower spindle shaft 4 are both provided with step grooves, and bearings are provided in the step grooves. The upper spindle shaft 3 is installed on the lower spindle shaft 4 through the bearings.

[0021] The twisted yarn of the present invention is routed as follows: it is drawn from the supply bobbin into the backing spindle tensioner and upper twisting disc, and then from the upper twisting disc upward into the first yarn inlet and first yarn outlet of the four-for-one twist spindle yarn separation device. It then exits and downward into the lower twisting disc yarn guide of the lower twisting disc, passes through the lower twisting disc yarn guide, and then upward into the four-for-one twist spindle yarn separation device, and then to the bobbin forming and winding device of the equipment (not shown). Because the upper and lower twisting discs of the four-for-one twist spindle are driven by the first and second spindle pulleys on the spindles to rotate in opposite directions, the purpose of applying four-for-one twist is achieved.

[0022] The principle of quadruple twisting is as follows: the yarn to be twisted is drawn from a stationary bobbin, passed through the top of the spindle tensioner (A), and then into the hollow spindle shaft, passing through the radial guide hole (B) of the upper twisting disc. The yarn segment AB to be twisted first rotates with the upper spindle shaft, acquiring one degree of twist with each rotation. The already twisted yarn segment AB is then drawn from the radial guide hole of the upper twisting disc and passes through the upper guide point (C). The rotation of the radial guide eyelet adds another twist to the yarn segment BC. Therefore, each rotation of the upper twisting disc of the quadruple twist spindle imparts two turns of twist in the same direction to the yarn.

[0023] The yarn passing through the upper guide point C descends into the lower twist disc's yarn guide, exits through the lower twist disc's yarn guide, and re-enters the four-for-one twist spindle's yarn splitting mechanism. At twist point D, because the lower twist disc rotates in the opposite direction of the upper twist disc, an additional twist is added to segment CD, similar to segments AB and BC. The yarn, having already been twisted three times, exits the lower twist disc's yarn guide through the lower twist disc's yarn guide hole, passes through the upper guide point E, and rotates through the upper guide eyelet of the yarn splitter, adding another twist to segment DE, for a total of four twists.
