The existing polyester filaments are more than a kilometer long, and the filaments are wound into balls. If there are still a lot of polyester filaments that have not been wound after the winding is completed, the filaments need to be broken. The existing broken wires are broken manually, and the operator needs to cut the filaments one by one.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in 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 making creative efforts belong to the scope of protection of the present invention.

[0021] As Figures 1 to 5 shown, a filament winding automatic wire-breaking device includes a wire outlet box 2 and a wire winding box 3; the wire winding box 3 has a feed inlet 31 and a discharge outlet 32, and a plurality of conveying rollers 33, a first mounting bracket 34 above the filament and another first mounting bracket 34 below the filament are installed in the wire winding box 3. Wire guiding mechanisms and wire-breaking mechanisms are symmetrically installed on the two first mounting brackets 34 in the vertical direction of the filament in sequence.

[0022] The wire guiding mechanism includes a push rod motor 41 installed on each first mounting bracket 34. A wire guiding plate 42 is provided on the push rod of the push rod motor 41, and a plurality of semi-circular wire guiding holes 43 are opened on the wire guiding plate 42.

[0023] The wire-breaking mechanism includes a first fixing plate 51, a lifting shaft 52 and a cam member 53. The first fixing plate 51 is fixed to a first mounting bracket 34 located above the long wire. First mounting plates 511 are installed on the front and rear sides of the first fixing plate 51. A servo motor 54 is installed on one side of the first mounting plate 511. A cam member 53 is drivingly connected to the output shaft of the servo motor 54. The cam member 53 also has a cam housing 531. A connecting plate 532 is fixed to one side of the cam housing 531. The connecting plate 532 is connected to the lifting shaft 52 for driving the lifting shaft 52 to move up and down. A first cutting knife 55 is also installed at the bottom of the cam housing 531. A second fixing plate 56 is also provided inside the wire winding box 3. A second cutting knife 57 is installed on the second fixing plate 56.

[0024] With the above structure, the long wire is released through the wire outlet box 2 and then transmitted to a number of conveying rollers through the feed inlet 31 of the wire winding box 3 for the conveying of the long wire. Subsequently, through the wire guiding mechanism, by starting the push rod motors 41 on the two first mounting brackets 34, the wire guiding plates 42 are moved above and below the long wire until the two wire guiding plates 42 are abutted against each other. At the same time, through the preset wire guiding semi-holes 43, the long wire is jointly limited at the same height of the wire winding box 3. And the wire guiding semi-holes 43 on the two wire guiding plates 42 can be spliced into a wire guiding circular hole, through which the long wire can just pass. And a plurality of wire guiding circular holes can be provided on the two wire guiding plates 42, which is beneficial to the wire guiding operation of multiple long wires and improves the wire guiding efficiency of the long wire. Subsequently, through the setting of the wire-breaking mechanism, during operation, the servo motor 54 on the first mounting plate 511 is started to drive the cam member 53 to rotate. The output shaft of the servo motor 54 is arranged on the surface of the cam member 53 close to the cam housing 531 for driving the cam to run along a circular track. When the cam member 53 rotates counterclockwise, during the process of the cam member 53 rotating from the lowest point to the highest point of the circular track, the first cutting knife 55 also moves along this track. During the movement, the long wire between the first cutting knife 55 and the second cutting knife 57 is cut while being in contact with the second cutting knife 57. And a number of wire-breaking mechanisms equal to the number of wire guiding semi-holes of the wire guiding mechanism are arranged in a row on the first mounting bracket 34 located above the long wire, which is beneficial to the wire-breaking treatment of multiple long wires, greatly improves the wire-breaking efficiency of the long wire, realizes batch wire-breaking, and has a high degree of automation.

[0025] Specifically, as Figures 1 to 5 shown, the first mounting bracket 34 further includes a cleaning mechanism. The cleaning mechanism includes a cleaning frame 61 and a cleaning brush 62. A cleaning frame 61 is installed on each first mounting bracket 34. A cleaning brush 62 is installed on the cleaning frame 61. One of the cleaning brushes 62 abuts against directly above the long wire, and the other cleaning brush 62 abuts against directly below the long wire for cleaning the dust and impurities on the long wire.

[0026] With the above structure, cleaning brushes 62 for cleaning impurities and dust on the surface of the filaments are arranged both above and below the filaments, which is conducive to automatically cleaning the filaments, improving the product quality of the filaments, and achieving good cleaning effect.

[0027] As Figures 1 to 5 shown, it further includes a winding mechanism. The winding mechanism includes a second mounting bracket 71. Second mounting plates 72 are symmetrically mounted on the left and right of the second mounting bracket 71. A number of driving motors 73 are symmetrically mounted on the second mounting plates 72. A lead screw 74 is connected in transmission to the output shaft of the driving motor 73. The lead screw 74 is connected to a winding frame 75. A slide rail 76 is mounted between the two second mounting plates 72. The winding frame 75 is slidably arranged on the slide rail 76. The winding frame 75 is provided with a winding roller 77.

[0028] By driving the lead screw 74 to rotate through the driving motor 73, and with the winding frame 75 arranged on the slide rail 76 and the winding frame 75 connected to the lead screw 74, when filament breakage is needed, the winding frame 75 can be finely adjusted to move slightly to the right, so that the filament can be straightened before filament breakage, greatly improving the quality of filament breakage and preventing the occurrence of non - broken filament phenomenon. By arranging a number of winding rollers 77 on the winding frame 75, the filaments can be wound quickly and conveniently, and the filaments can be wound in batches, integrating wire guiding and filament breakage.

[0029] As Figures 1 to 5 shown, the cutting surfaces of the first cutting knife 55 and the second cutting knife 57 are arranged as inclined surfaces in opposite directions.

[0030] By arranging the cutting surfaces of the first cutting knife 55 and the second cutting knife 57 as inclined surfaces in opposite directions, it is conducive to strengthening the shearing force of the filaments by the first cutting knife 55 and the second cutting knife 57, and significantly improving the success rate of filament breakage.

[0031] As Figures 1 to 5 shown, the output shaft of the servo motor 54 is arranged at a position on the surface of the cam member 53 close to the cam housing 531, for driving the cam to run along a circular track.

[0032] As Figures 1 to 5 shown, a semi - circular limiting portion 8 is provided in the semi - circular wire guiding hole 43 on the wire guiding plate 42. By arranging the semi - circular limiting portion 8 in the semi - circular wire guiding hole 43, the filaments are further guided, improving the integrity during filament transportation.

[0033] As Figures 1 to 5 shown, the filaments are released from the wire outlet box 2, and sequentially pass through a number of conveying rollers 33, a wire guiding mechanism, a cleaning mechanism, a filament breakage mechanism, and then are wound by the winding rollers 77 on the winding mechanism. Through such operation steps, the integration efficiency of the device is high, and filament breakage can be effectively carried out in batches.
