[0002] With the continuous advancement of textile technology, the types and specifications of chemical fiber yarns are becoming increasingly abundant. Yarn is a kind of textile that is processed into products of a certain fineness using various textile fibers. It is used for weaving, rope making, thread making, knitting and embroidery, etc. It is divided into short fiber yarn, continuous filament, etc., and the requirements for shearing devices are also getting higher and higher.

[0003] In the production of chemical fiber yarns, multiple strands of yarn need to be combined and rewound. First, multiple strands of chemical fiber yarns are combined through a specific combining device, and the combined yarns are then guided to a yarn cutting device for winding.

DETAILED DESCRIPTION

[0032] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0033] like Figure 1 As shown, a yarn shearing device for chemical fiber yarn production comprises: a yarn winding shearing machine 11, a winding box 13 is provided on the front of the yarn winding shearing machine 11, a plurality of groups of wire wheel assemblies 12 are provided above the winding box 13, a plurality of paper reel seats 14 corresponding to the wire wheel assemblies 12 are provided inside the winding box 13, a winding paper reel 15 is fixed on the paper reel seat 14, a group of twisting and cutting mechanisms 2 and a wire management mechanism 3 are provided in the yarn passing area of ​​the winding box 13, when the amount of yarn wound on the winding paper reel 15 reaches a specified value, the yarn is cut by embedding the wire management mechanism 3 into the twisting and cutting mechanism 2, and the yarn head away from one end of the winding paper reel 15 is tightened;

[0034] After the chemical fiber yarn is output from the raw material supply end, it is transferred to the winding paper drum 15 in the winding box 13 through a plurality of groups of wire passing wheel assemblies 12. When the winding amount on the winding paper drum 15 reaches a specified value, the yarn is cut by the wire arrangement mechanism 3 and the rubbing and cutting mechanism 2.

[0035] The winding length is detected by a yarn strand length measuring instrument installed on the yarn winding shearing machine 11, and when the specified value is reached, the operation of the wire management mechanism 3 is controlled.

[0036] like Figure 1 - Figure 3 , Figure 6 and Fig. 9 As shown, the rubbing and cutting mechanism 2 includes a wire passing plate 21, a wire pressing middle plate 22 is provided below the wire passing plate 21, and a horizontal rubbing knife 23 is provided below the wire pressing middle plate 22;

[0037] The wire management mechanism 3 includes a push plate 31, a wire pushing main plate 32 is fixedly arranged on one side of the push plate 31 close to the rubbing and cutting mechanism 2, a wire pushing auxiliary plate 33 rotatably connected to the push plate 31 is arranged below the wire pushing main plate 32, a gate cutter 34 is arranged on one end of the wire pushing auxiliary plate 33 close to the rubbing and cutting mechanism 2, and a wire suction member is arranged on the upper surface of the gate cutter 34;

[0038] When the winding paper drum 15 has finished winding the yarn, the wire pushing main plate 32 and the wire pushing auxiliary plate 33 of the wire management mechanism 3 are inserted into the gap between the wire passing plate 21 and the wire pressing middle plate 22 of the rubbing and cutting mechanism 2 to press the cut yarn end. Then, the wire pushing auxiliary plate 33 is rotated downward by 90°, so that the wire suction member adsorbs the yarn end onto the gate cutter 34 and is pulled out.

[0039] The wire management mechanism 3 and the cutting mechanism 2 are both F-shaped, the wire pressing middle plate 22 and the wire passing plate 21 are the F-shaped horizontal bar parts of the cutting mechanism 2, the wire pushing main plate 32 and the wire pushing auxiliary plate 33 are the F-shaped horizontal bar parts of the wire management mechanism 3, the wire pressing middle plate 22 and the wire passing plate 21 are staggered with the wire pushing main plate 32 and the wire pushing auxiliary plate 33, an electric push rod 306 is fixedly provided on the side of the pushed plate 31 away from the cutting mechanism 2, and push knife sliders 38 slidably connected to the winding box 13 are fixedly provided on both sides of the pushed plate 31.

[0040] like Figure 1 , Figure 4 and Figure 7 As shown, a liquid storage bladder 24 is fixedly provided at one end of the wire pressing middle plate 22 close to the wire organizing mechanism 3, an inner liquid bladder 25 is provided inside the liquid storage bladder 24, a plurality of support columns 26 are fixedly provided in the space between the inner liquid bladder 25 and the liquid storage bladder 24, the inner liquid bladder 25 and the liquid storage bladder 24 are not connected to each other, and both the inner liquid bladder 25 and the liquid storage bladder 24 are filled with liquid.

[0041] A rubbing slider 28 is fixedly provided on the side of the horizontal rubbing knife 23 away from the wire organizing mechanism 3, and a complex rubbing spring 29 is fixedly provided at both ends of the rubbing slider 28. Two symmetrical telescopic columns 27 are fixedly provided at the center position of the rubbing slider 28, and the expansion and extension directions of the two telescopic columns 27 are opposite. The two telescopic columns 27 are respectively connected to the inner liquid bag 25 and the liquid storage soft bag 24 through a hose, and the rubbing slider 28 forms a sliding connection with the F-shaped vertical bar part of the rubbing and cutting mechanism 2.

[0042] When the winding paper drum 15 has finished winding the yarn, the electric push rod 306 pushes the pushed plate 31 to slide toward the side of the rubbing and cutting mechanism 2, and drives the pushed plate 31 to insert into the gap between the wire passing plate 21 and the wire pressing middle plate 22, and drives the wire pushing sub-plate 33 to insert into the gap below the wire pressing middle plate 22, so that the yarn is arranged in an S shape through the wire pushing main plate 32 and the wire pushing sub-plate 33. The wire pushing main plate 32, the wire pushing sub-plate 33, the wire passing plate 21 and the wire pressing middle plate 22 can clamp the yarn to prevent the yarn from being slid in the horizontal direction. After the rubbing knife 23 and the gate cutter 34 cut the yarn, the end away from the winding paper drum 15 rebounds. Because the chemical fiber yarn is made of fiber filaments, it has the characteristics of good elasticity and strong wrinkle resistance. When winding, the chemical fiber yarn is tightened. Once the yarn is cut, it will rebound. After that, the staff needs to re-arrange and thread the yarn. Therefore, the main pusher plate 32, the auxiliary pusher plate 33, the wire passing plate 21 and the wire pressing middle plate 22 can clamp the yarn, which can effectively fix the yarn and prevent the yarn away from the end of the winding paper drum 15 from rebounding;

[0043] When the wire pushing main board 32 and the wire pushing sub-board 33 are pushed to the end position, the liquid storage soft capsule 24 and the inner liquid capsule 25 are squeezed, and the liquid in the liquid storage soft capsule 24 and the inner liquid capsule 25 will flow into the two telescopic columns 27 along the hose. Because the liquid storage soft capsule 24 is outside the inner liquid capsule 25, the liquid storage soft capsule 24 is squeezed first, so that one of the telescopic columns 27 pushes the rubbing slider 28 to slide first, and finally drives the horizontal rubbing knife 23 and the gate cutter 34 to form a tangent to the yarn cutting. If the yarn is directly sheared by the horizontal rubbing knife 23 and the gate cutter 34 like a scissors, it will not succeed. At this time, the left and right movement of the horizontal rubbing knife 23 can rub and cut the yarn.

[0044] like Figure 1-4 , Figure 6 and Fig. 9 As shown, the wire suction member includes a rotating drum 303 rotatably connected to the vertical bar portion of the wire management mechanism 3F-shaped, coil springs 304 are fixedly arranged inside both ends of the rotating drum 303, and a plurality of expansion water bags 305 are fixedly arranged between the gaps of the coil springs 304. The plasticity of the coil spring 304 is changed by the expansion of the plurality of expansion water bags 305 with liquid injection, thereby driving the wire pushing sub-plate 33 to rotate counterclockwise.

[0045] The wire suction component also includes a second liquid storage bladder 37 fixed at the connection point between the wire pushing sub-plate 33 and the gate cutter 34. The interior of the second liquid storage bladder 37 is filled with liquid. The liquid outlet pipe of the second liquid storage bladder 37 runs through the wire pushing sub-plate 33, and the liquid outlet pipe of the second liquid storage bladder 37 is in an hourglass shape at one end close to the second liquid storage bladder 37. The liquid outlet pipe of the second liquid storage bladder 37 is interconnected with a plurality of expansion water bags 305.

[0046] The wire suction component also includes an air supply box 39 fixed on one side of the push knife slider 38, the air outlet end of the air supply box 39 is connected to the exhaust pipe 301 fixed on the lower wall of the push wire sub-plate 33, the other air inlet end of the exhaust pipe 301 is connected to the manifold 302, the upper wall of the gate cutter 34 is provided with a wire suction port 35, a plurality of groups of negative pressure holes 36 are provided in the wire suction port 35, and the manifold 302 and the plurality of groups of negative pressure holes 36 are connected to each other.

[0047] When the horizontal rubbing knife 23 and the gate cutter 34 shear the yarn, the second liquid storage soft capsule 37 is squeezed at the same time, and the liquid in the second liquid storage soft capsule 37 flows into the plurality of expansion water capsules 305. The liquid in the second liquid storage soft capsule 37 flows into the plurality of expansion water capsules 305, and the liquid discharge is fast and the return is slow, so that the shape of the coil spring 304 changes. After that, when the gate cutter 34 and the horizontal rubbing knife 23 are out of the tangent state, the pusher plate 33 rotates counterclockwise under the drive of the coil spring 304, so that the yarn clamped between the pusher plate 33 and the wire pressing middle plate 22 naturally hangs down, and the other parts of the yarn are still clamped, so that the staff can replace the new winding paper drum 15 later, which is more convenient for binding the yarn and preventing the yarn from rebounding;

[0048] When the pushed plate 31 is pushed out, the air supply box 39 is stretched, so that air enters the air supply box 39. After the horizontal rubbing knife 23 and the gate cutting knife 34 cut the yarn, the two air supply boxes 39 are slowly squeezed in the process of pulling the pushed plate 31 back by the electric push rod 306. At this time, the air in the air supply box 39 will be discharged from the exhaust pipe 301. Therefore, under the action of the air pressure difference, the cut yarn head will be adsorbed on the wire suction port 35, thereby cooperating with the counterclockwise rotation of the wire pushing sub-plate 33 to pull out the yarn head, eliminating the need for the staff to re-arrange the wires.

[0049] like Figure 2 , Figure 5 and Figure 8 As shown, a wire passing opening 41 is opened at the center position of the wire passing plate 21 near one end of the wire management mechanism 3, and a wire twisting plate 42 is arranged inside the wire passing opening 41. A transmission column 45 that passes through the wire passing plate 21 is fixedly arranged on one side of the wire twisting plate 42, and the transmission column 45 is rotatably connected to the wire passing plate 21.

[0050] A force disk 46 rotatably connected to the wire passing plate 21 is fixedly provided at one end of the transmission column 45 away from the wire twisting plate 42, and the thickness of the force disk 46 gradually decreases. A swing plate 47 rotatably connected to the wire passing plate 21 is provided on the side of the force disk 46 away from the transmission column 45, and a thrust ball 48 is fixedly provided on the swing plate 47. A semicircular limit disk 49 is fixedly provided on the side wall of the transmission column 45 close to one end of the wire twisting plate 42.

[0051] A magnetic block 43 is fixedly disposed on the upper wall of the wire pushing main board 32 . A pushing plate slot 44 is formed on one side of the magnetic block 43 . The magnetic block 43 and the swing plate 47 attract each other.

[0052] The liquid storage soft bag 24 contains liquid, which plays a role in cooling the yarn when it passes through the liquid storage soft bag 24;

[0053] When the yarn is wound, it needs to pass through the twisting plate 42. Then, when the magnetic block 43 is pushed into the gap between the wire passing plate 21 and the wire pressing middle plate 22 along with the wire pushing main board 32, the magnetic block 43 passes through the swing plate 47. Under the action of suction, the swing plate 47 is turned out and stuck in the pushing plate groove 44. As the wire pushing main board 32 continues to go deeper, the swing plate 47 is driven to rotate, and the thrust ball 48 pushes the force disk 46 to rotate 180°. The force disk 46 drives the twisting plate 42 to rotate 180°, and the yarn is twisted around the twisting plate 42 in an S shape, thereby increasing the friction of the yarn. Finally, only when the winding continues, the yarn is subjected to tension, and under the reverse tension, the twisting plate 42 returns to its original position.

[0054] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
