An automatic switching twisting winding machine with flyer

Abstract

The invention discloses an automatic switch twisting winding machine with spindle wings. The automatic switch twisting winding machine with the spindle wings comprises a mechanical executing mechanism and an electric control part. The electric control part is controlled by printer control language (PCL). The mechanical executing mechanism comprises a rack, a spindle system arranged on the rack, a spindle wing system arranged on the rack, a repiece system arranged on the rack, a pneumatic wire cutting system arranged on the rack, a spindle wing lifting system arranged on the rack, a wire crossing system arranged on the rack and a wire pressing system arranged on the rack. A bobbin is inserted in a bobbin seat on the spindle and rotates with rotation of the spindle and drives the spindle wings to wind undrawn wires to enable the wire bundles to obtain twist degree. After a full bobbin, a series of movements of bobbin changing, repiecing, wire pressing, wire crossing and wire cutting and continuous winding of screw pitches are achieved. The automatic switch twisting winding machine with the spindle wings can adapt to automatic continuous winding of random winding diameters.

Description

technical field [0001] The invention relates to an automatic switching twisting winding machine, in particular to an automatic switching twisting winding machine with a flyer. Background technique [0002] The winding machine is a main unit machine in the combined chemical fiber spinning unit; the winding machine of the present invention refers to the device used to wind the raw fiber into a certain package bobbin for further post-processing during melt spinning. special machinery. [0003] Devices for automatically switching and winding undrawn yarn (UDY) of melt-spun chemical fibers are known; But its winding wire is untwisted. In some special products, the post-processing requires that the undrawn wire must be twisted (low twist), which makes the conventional winding head useless. [0004] The disadvantages of using a ring-spindle winding machine for automatic switch twisting and winding are as follows: [0005] 1. When processing some special products, the monofilamen...

AI Technical Summary

Problems solved by technology

[0005] 1. When processing some special products, the monofilament fineness is high, and the multifilament fineness reaches tens of thousands of deniers (the multifilament fineness of traditional twisted products is generally below 2000 deniers). In this case, the wire hook must be selected Heavy weight; this not only increases the tension of the wire and the chance of breaking the end, but also increases the friction between the wire hook and the steel ring, resulting in high temperature, which aggravates the wear and tear of the wire hook and makes it unable to withstand itself. Fly off from the steel ring due to centrifugal force, resulting in wire breakage

[0006] 2. UDY is mostly a large package; the increase in the diameter of the package will inevitably increase the diameter of the steel ring; the two factors of it and the heavy wire hook will increase the centrifugal force of the wire hook, which will easily cause the wire hook to fly off

[0007] 3. During automatic winding and doffing, the bobbin turntable must rotate to complete the switch between empty and full bobbins; at this time, it is necessary to stop the rotation of the thread on the bobbin in advance; and the wire hook drags the thread on the bobbin. In the state of the steel ring turning upwards, it is difficult to use active coercive means to stop the spinning of the thread and maintain the purpose of normal winding

[0008] 4. The automatic winding must be automatically threaded. When the can is changed, the turntable with the steel ring and the spindle rotates, and the thread still stays on the full tube, and the thread can automatically pass through the wire hook on the edge of the steel ring. It is undoubtedly more complicated to wind on the empty bobbin for spinning, especially if the wire hook flies off during normal winding operation, it will be more difficult to automatically replace and regenerate.

[0009] In addition, if the flyer type twisting method cannot adjust the balance between the winding speed and the spinning line speed by itself, and needs to increase the mechanical variable speed transmission and automatic control, it will be even more rejected.
