Description

Technical Field

[0001] The utility model relates to the technical field of false twisters, in particular to a false twister device with an anti-escape twist function. Background Art

[0002] In the prior art, when a friction disk type false twister twists a yarn, the yarn is introduced from the friction disk at the uppermost part of the false twister, passes through all the friction disks at the positions between each rotating shaft, and then is led out from the friction disk at the lowermost part to complete the false twisting, and the false twisting effect on the yarn is achieved through friction.

[0003] After the friction disk contacts the wire, due to friction, while driving the wire to twist, it will also drive both ends of the wire to jump, making the wire unable to remain stable during twisting, and very likely to produce defective products such as looseness. For this reason, we propose a false twister device with an anti-escape twist function. Summary of the Utility Model [[ID=IS]]

[0004] The utility model provides a false twister device with an anti-escape twist function, which has the advantage of fixing both ends of the wire during twisting, and solves the problems raised in the above background art.

Driven by the lifting mechanism, the first strip-shaped plate descends to the top of the second strip-shaped plate, so that there is a gap between the upper and lower transmission belts, and the upper and lower transmission belts rotate in opposite directions, thereby twisting the wire.

[0007] Preferably, the lifting mechanism includes a telescopic mechanism and a guide shaft vertically arranged on the base. On the side surface of the first strip-shaped plate, there are provided an L-shaped frame and a guide seat. The L-shaped frame is connected to the top of the telescopic mechanism, and the guide shaft is movably placed in the guide seat.

Detailed implementation manner

[0020] Next, the technical solution of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Refer to Figures 1 to 5 , the present invention provides a technical solution: a false twister device with an anti-escape twisting function, including two identical twisting mechanisms 9. The twisting mechanisms 9 are arranged on the base 1, and the two twisting mechanisms 9 are symmetrically arranged. During use, two strands of wire are respectively located in the two twisting mechanisms 9, and the two twisting mechanisms 9 twist the wire, and then the twisted ends are automatically wound together;

[0022] As Figure 1 shown, each twisting mechanism respectively includes a first strip plate 6 and a second strip plate 14 arranged in parallel. The second strip plate 14 is located below the first strip plate 6. Driving wheels 2 are respectively rotatably installed at both ends of one side of the first strip plate 6 and the second strip plate 14. A driving motor 4 connected to the driving wheel 2 is provided at one end of the other side of the first strip plate 6 and the second strip plate 14. Transmission belts 3 are respectively provided on the sides of the first strip plate 6 and the second strip plate 14 away from the driving motor 4 and are placed on the driving wheels 2. The transmission belts 3 are synchronous belts, and the driving wheels 2 are synchronous wheels;

[0023] Importantly, the outer diameter of the driving wheel 2 is greater than the height of the first strip plate 6 and the second strip plate 14, and the outer surface of the transmission belt 3 is exposed outside the driving wheel 2. Such a design is very necessary. During use, only the surfaces of the two transmission belts 3 can be in contact, and the first strip plate 6 and the second strip plate 14 do not contact each other;

[0024] As Figure 2 shown, the bottom of the second strip plate 14 is connected to the base 1 through a support 16. The supports 16 are at least two and are symmetrically arranged, and the middle part of the side of the first strip plate 6 away from the driving wheel 2 is connected to the base 1 through a lifting mechanism. As Figure 2As shown in the figure, the lifting mechanism includes a telescopic mechanism 12 and a guide shaft 15 vertically arranged on the base 1. The telescopic mechanism 12 is a cylinder or an electric lifting rod. An L-shaped frame 7 and a guide seat 13 are provided on the side surface of the first strip plate 6. The L-shaped frame 7 is connected to the top of the telescopic mechanism 12, and the guide shaft 15 is movably placed inside the guide seat 13;

[0025] It should be noted that the L-shaped frame 7 is designed to be L-shaped to increase the height of the telescopic shaft of the telescopic mechanism 12, so that when the telescopic mechanism 12 drives the first strip plate 6 to lift and lower, it can have a greater stroke. Specifically, the telescopic mechanism 12 drives the first strip plate 6 to move up and down, and the provided guide shaft 15 can make the first strip plate 6 lift and lower more stably without deflection;

[0026] Therefore, driven by the lifting mechanism, the first strip plate 6 is lowered to the top of the second strip plate 14, so that there is a gap between the upper and lower transmission belts 3. The wire to be twisted is placed in this gap, and the upper and lower transmission belts 3 rotate in opposite directions, so as to twist the wire. The surface of the transmission belt 3 is a rubber layer, which can increase the friction and prevent the wire from rotating during twisting. In order to prevent the upper and lower transmission belts 3 from deforming after contact, as Figure 1 shown, pressing plates 5 are respectively vertically provided on the bottom side surface of the first strip plate 6 and the top side surface of the second strip plate 14. The pressing plates 5 are used to support the transmission belt 3, so that no matter how the transmission belt 3 clamps the wire, the transmission belt 3 will not deform.

[0027] When the transmission belt 3 rotates to twist the wire, if the two ends of the wire are not fixed, it will swing. Therefore, the most important thing in this application is that limit seats 11 are respectively provided on both sides of the relative ends of the two twisting mechanisms 9, and limit ports 10 are opened at the tops of the limit seats 11. As Figure 2 and Figure 3 shown, the limit seats 11 are respectively arranged on the base 1. During use, the wires in each twisting mechanism 9 are respectively fixed by the limit ports 10 on both sides. Because when the wire is twisted, the wire is clamped by the upper and lower transmission belts 3, the wire will not move up and down. One end of the wire is fixed by the wire rack, and the other end is fixed by the winding machine. Therefore, when the wire passes through the limit port 10, the wire can be kept stable during twisting.

[0028] As Figure 3 shown, since one end of the wire is twisted during the twisting process, a device for fixing the wire needs to be provided at the wire inlet end of the false twister device, so as to prevent the wire inlet end from rotating along with the twisting. Therefore, a support arm 8 is vertically connected to the side surface of each first strip plate 6 near the limit seat 11, and a pressing wheel 19 is rotatably installed on the side surface of the support arm 8 far away from the first strip plate 6;

[0029] A grooved pulley 18 is provided directly below the pressing wheel 19. The position of the grooved pulley 18 corresponds to the limit port 10, and the grooved pulley 18 is rotatably installed on the bracket 17, and the bottom of the bracket 17 is arranged on the base 1. During use, when the upper and lower transmission belts 3 come into contact, the pressing wheel 19 is also placed inside the grooved pulley 18 at this time. Rubber layers are provided on the circumferential side of the pressing wheel 19 and the inner bottom surface of the grooved pulley 18, and the upper and lower rubber layers are in elastic contact. Since the end of the wire being twisted is driven by the winding machine, the wire located between the transmission belts 3 is also constantly moving. When the pressing wheel 19 presses the wire tightly inside the grooved pulley 18, since both the pressing wheel 19 and the grooved pulley 18 are rotating, the wire will drive the pressing wheel 19 and the grooved pulley 18 to rotate during the movement of the wire, resulting in the wire being able to only move along the rolling direction of the pressing wheel 19 and the grooved pulley 18, and cannot be torsionally twisted circumferentially, further enhancing the stability of twisting.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
