Problems solved by technology

The present invention replaces the manual operation of twisting pins in the current silk reeling process; it solves the problem of thread sheaths between thread and thread caused by the same operator in different time periods or between different operators due to the difference in strength or proficiency. Different lengths, loose sheaths, hanging sheaths, etc.; changing the traditional operation mode of one thread with one artificial silk sheath or one thread with an independently driven false twister, and finally achieve the purpose of reducing labor intensity and improving raw silk quality

Embodiment 1

[0030] Reeling 20 / 22D spring cocoon raw silk, the thread 2 passes through the thread collector 1 and the lower guide wire hook 3 in sequence, and then clings to the lower arched twisting disc (the depth is 15mm, the opening width is 75mm) and the upper arched twisting disc (depth 15mm, opening width 75mm) on the inner wall and through the upper guide wire hook. The opening direction of the upper and lower arched twist discs is consistent. The motor drives the driving wheel 6 to rotate through the output shaft. The rotation of the driving wheel drives the crank 5 to make a circular motion, and the crank 5 drives the rocker 7 to reciprocate. The reciprocating linear motion of the plate 14, and the swing of the two rockers 8 and 11 make the upper reciprocating plate 9 do linear motion in the opposite direction, the moving speed is 50 times / min, and the moving distance is 30 mm. The reciprocating linear motion of the arched twisting disc makes the thread on it rotate around its...

Embodiment 2

[0032]Reeling 20 / 22D spring cocoon raw silk, the thread 2 passes through the thread collector 1 and the lower guide wire hook 3 in sequence, and then clings to the lower arched twisting disc (the depth is 27mm, the opening width is 60mm) and the upper arched twisting disc (depth 27mm, opening width 60mm) on the inner wall and through the upper guide wire hook. The opening direction of the upper and lower arched twist discs is consistent. The motor drives the driving wheel 6 to rotate through the output shaft. The rotation of the driving wheel drives the crank 5 to make a circular motion, and the crank 5 drives the rocker 7 to reciprocate. The reciprocating linear motion of the plate 14, and the swing of the two rockers 8 and 11 make the upper reciprocating plate 9 do linear motion in the opposite direction, the moving speed is 100 times / min, the moving distance is 20 mm, and the arched twist disc The reciprocating linear motion makes the thread on it rotate around its own axis...

Embodiment 3

[0034] Reeling 20 / 22D autumn cocoon raw silk, the thread 2 passes through the thread collector 1 and the lower guide wire hook 3 in sequence, and then clings to the lower arched twisting disc (depth: 30mm, opening width: 50mm) and upper arched twisting disc (depth 30mm, opening width 50mm) on the inner wall and through the upper guide wire hook. The opening directions of the upper and lower arched twist discs are opposite. The motor drives the driving wheel 6 to rotate through the output shaft. The rotation of the driving wheel drives the crank 5 to make a circular motion. The reciprocating linear motion of the plate 14, and the swing of the two rockers 8 and 11 make the upper reciprocating plate 9 do linear motion in the opposite direction, the moving speed is 150 times / min, the moving distance is 10 mm, and the arch twist disc The reciprocating linear motion makes the thread on it rotate around its own axis, and the reeled small For silk flakes, the moisture regain of doff...

Abstract

The invention discloses a strand false twisting device and a strand false twisting method in a silk reeling process. One end of a crank is fixed at the center position of a driving plate, the other end of the crank is connected with a rocker, the other end of the rocker is fixed on the lower reciprocation plate, a plurality of arc-shaped twisting plates are respectively fixed on an upper reciprocation plate and the lower reciprocation plate, the center of a left rocker and the center of a right rocker are fixed by pins, and two ends of the left rocker and two ends of the right rocker are respectively installed in a sliding groove of the upper reciprocation plate and a sliding groove of the lower reciprocation plate. Manual operation of croisure twisting in the existing twisting process is substituted, the problems that due to the fact that energizing extent or proficiency of the same operator in different time sections or different operators is different, croisure length is different between flosses and croisure is loosened or hung are solved, the traditional operation method, that one floss one labor croisure or one floss one independent transmission, of the false twisting device is changed, finally labor intensity is reduced and quality of raw silk is improved.

Description

technical field [0001] The invention relates to a silk reeling device, in particular to a thread false twisting device and method used in the silk reeling process. Background technique [0002] Silk reeling is to assemble several cocoon silks together according to the requirements of specification fineness. Since the cocoon silk in silk reeling is extracted from the wet cocoon, the thread contains a lot of water. If it is directly wound into shape, it will not only be difficult to dry, affect the color of the silk, but also make the thread stick to each other to form a hard glue thread. When re-shaking, the thread is not easy to unwind, and it is easy to cause cutting. Therefore, in the silk reeling process, after the threads of the cocoons in the silk reeling pass through the thread collector, they cannot be directly wound on the small superior. At the same time, in the silk reeling process, in addition to removing excess water, it is also necessary to make the cross se...
