[0002] A false twist machine is a textile processing equipment, which is mainly used to false-twist silk threads to improve their gloss, softness, elasticity and other qualities. The false twist machine uses the friction and tension inside the yarn to twist the yarn itself, and uses the yarn's own stretching and retraction properties to form twist.

An automatic clamping component is provided on the rotating shaft inside the bearing seat, and an automatic clamping component is provided on the other side of the corresponding bearing seat through the rotating shaft. The two automatic clamping components are used to clamp and unload the bobbin. The utility model inserts the two ends of the bobbin into the interior of the clamping disk, and due to the action of the spring, the bobbin is automatically clamped. The two ends of the yarn tube are tightened by the inward extrusion force. When the yarn tube is almost full of warp yarn, the electromagnet is connected to make it magnetically attract the iron block, so that the clamping disk is sucked to one side of the turntable, and the yarn tube will be separated from the clamping disk to achieve loosening and unloading. Repeating this operation, the yarn winding length is basically the same, which can significantly improve the yield rate, and this bobbin dropping method is more convenient to operate and is an automatic unloading process. However, this utility model will cause squeezing of the spring when installing and disassembling the yarn tube multiple times, which will cause the spring to deform and damage, affecting the normal use of the spring and reducing the effect of clamping the yarn tube.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 In this embodiment, a false twisting machine capable of automatically dropping yarns comprises a supporting seat 1, an inner cavity of the supporting seat 1 is provided with a yarn bobbin 2, opposite sides of the left and right side walls of the inner cavity of the supporting seat 1 are provided with a dropping mechanism 3 for automatically dropping yarns, and the tops of the left and right ends of the inner front wall of the supporting seat 1 are provided with a cutting mechanism 4 for cutting yarns.

[0023] Among them, a collecting seat with a U-shaped cross-section is fixed to the inner bottom wall of the supporting seat 1, and an anti-skid pad is fixed to the inner bottom wall of the collecting seat, and the anti-skid pad is a rubber pad.

[0024] See also Figure 2-3In order to improve the effect of fixing and clamping the bobbin 2, the bobbin-dropping mechanism 3 in this embodiment includes a rotating shaft 301 rotatably connected to the opposite side of the left and right side walls of the inner cavity of the bearing seat 1 through a bearing, and a rotating plate 302 is fixed on the opposite side of the two rotating shafts 301. A No. 1 motor 303 is fixed on the upper surface of the left end rotating plate 302. The output shaft of the No. 1 motor 303 passes through the left end rotating plate 302 and extends to the inner cavity of the left end rotating plate 302 and is fixed with a rotating rod 304. The upper and lower ends of the outer surface of the rotating rod 304 are fixed with rotating gears 305. When the yarn is wound on the outer surface of the bobbin 2, the yarn is firstly wound. The cylinder 2 is located between the two rotating plates 302, and then the No. 1 motor 303 is started. The rotation of the No. 1 motor 303 drives the rotating rod 304 to rotate, and the rotation of the rotating rod 304 drives the two rotating gears 305 to rotate. The back of the rotating gear 305 is meshed and connected with a toothed rod 306. The right side of the two toothed rods 306 is fixed with the same clamping plate 307. The rotation of the rotating gear 305 drives the toothed rod 306 to move rightward. The movement of the two toothed rods 306 can push the clamping plate 307 to move rightward until the clamping plate 307 and the right end rotating plate 302 clamp and fix the yarn cylinder 2, thereby improving the effect of fixing and clamping the yarn cylinder.

[0025] In this embodiment, a second motor 5 is fixed to the right side of the support base 1 , and the output shaft of the second motor 5 passes through the right side wall of the inner cavity of the support base 1 and extends to the inner cavity of the support base 1 and is fixed to the right rotating shaft 301 .

[0026] Among them, the shape of the left end rotating plate 302 is a cylinder with a hollow interior and partially missing on the left and right sides. A telescopic rod is provided between the clamping plate 307 and the opposite side of the left end rotating plate 302. The inner cavity of the gear rod 306 is slidably connected to the limit rod, and a pulley is fixed on the left side of the limit rod. An annular groove is opened on the left side wall of the inner cavity of the supporting seat 1, and the two pulleys rotate in the inner cavity of the annular groove.

[0027] In addition, one end of the yarn is fixed on the yarn tube 2, and then the No. 2 motor 5 is started. The output shaft of the No. 2 motor 5 rotates and then drives the right end rotating plate 302 to rotate. The rotation of the right end rotating plate 302 can drive the yarn tube 2 to rotate, thereby causing the left end rotating plate 302 to rotate. At this time, the pulley rotates in the inner cavity of the annular groove, and the yarn can be wound around the yarn tube 2.

[0028] See also Figure 4 In order to cut the yarn wound on the surface of the yarn tube 2, the cutting mechanism 4 in this embodiment includes an electric telescopic column 401 at the top of the left and right ends of the inner wall of the supporting seat 1, a blade 402 is fixed on the upper surface of the electric telescopic column 401, and a positioning frame 403 is fixed in the middle of the lower surface of the blade 402.

[0029] Among them, the two electric telescopic columns 401 are symmetrically distributed at the left and right ends of the vertical central axis of the blade 402. A positioning groove is opened on the top of the middle part of the inner wall of the supporting seat 1. The two electric telescopic columns 401 are started, and the extension of the electric telescopic columns 401 drives the blade 402 to move upward. The movement of the blade 402 can drive the positioning frame 403 to move upward in the inner cavity of the positioning groove, and then the yarn can be cut. The bottom of the positioning frame 403 makes linear up and down motion in the inner cavity of the positioning groove, and the cross-sectional shape of the positioning frame 403 is L-shaped.

[0030] It is understandable that after the yarn is cut, the No. 1 motor 303 can be started to reverse, so that the yarn tube 2 can be released and fall into the inner cavity of the collecting seat, realizing the process of automatic tube drop, which is convenient for the staff to pick up.

[0031] The working principle of the above embodiment is:

[0032] (1) When winding the yarn on the outer surface of the bobbin 2, the bobbin 2 is first placed between the two rotating plates 302, and then the No. 1 motor 303 is started. The rotation of the No. 1 motor 303 drives the rotating rod 304 to rotate, and the rotation of the rotating rod 304 drives the two rotating gears 305 to rotate. The rotation of the rotating gear 305 drives the gear rod 306 to move rightward. The movement of the two gear rods 306 can push the clamping plate 307 to move rightward. At this time, the gear rod 306 slides to the right on the outer surface of the limit rod, and the clamping plate 307 moves to the right. The movement can drive the telescopic rod to extend, and thus limit the movement of the clamping plate 307 until the clamping plate 307 and the right-end rotating plate 302 clamp and fix the yarn tube 2, and fix one end of the yarn on the yarn tube 2. Then start the No. 2 motor 5, and the output shaft of the No. 2 motor 5 rotates, thereby driving the right-end rotating plate 302 to rotate. The rotation of the right-end rotating plate 302 can drive the yarn tube 2 to rotate, thereby causing the left-end rotating plate 302 to rotate. At this time, the pulley rotates in the inner cavity of the annular groove, and then the yarn can be wound around the yarn tube 2.

[0033] (2) When the yarn tube 2 is wound with the appropriate yarn, the second motor 5 is stopped and the two electric telescopic columns 401 are started. The extension of the electric telescopic columns 401 drives the blade 402 to move upward. The movement of the blade 402 can drive the positioning frame 403 to move upward in the inner cavity of the positioning groove, so that the yarn can be cut. Then, the first motor 303 is started to reverse, so that the yarn tube 2 can be released and fall into the inner cavity of the collecting seat, which is convenient for the staff to pick up.
