[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figs. 1-6 As shown, this embodiment proposes a cutting device for weaving, including a workbench 1. Both ends of the workbench 1 are rotatably connected to conveying rollers 2 for conveying fiber cloth. A first motor 3 is fixedly installed at one end of the workbench 1. The first motor 3 is a servo motor and the speed of the output shaft can be adjusted. The output shaft of the first motor 3 is fixedly connected to one of the conveying rollers 2.

[0028] Both ends of the workbench 1 are fixedly connected to mounting bases 4. A cutting mechanism 5 is provided between the two mounting bases 4. The cutting mechanism 5 includes a mounting frame 51. The two ends of the bottom of the mounting frame 51 are fixedly connected to the two mounting bases 4 respectively. A movable rod 52 that passes through the top wall of the mounting frame 51 is slidably connected to the middle of the mounting frame 51. A hot cutting blade 53 is fixedly connected to the bottom end of the movable rod 52. A blade groove 7 that slides with the hot cutting blade 53 is provided on the top of the workbench. Heaters 54 (conventional electric heating elements in the prior art, which will not be described in detail) are provided at both ends of the top of the hot cutting blade 53. A driving component 55 is provided on the top of the movable rod 52 to drive the movable rod 52 to slide up and down. A cleaning component 56 is provided on the inner side of the mounting frame 51 to clean the outer wall of the hot cutting blade 53 by cooperating with the sliding of the hot cutting blade 53.

[0029] The drive component 55 drives the movable rod 52 to slide up and down, allowing the hot cutting blade 53 to move up and down. When the hot cutting blade 53 moves downward and engages with the blade groove 7, it cuts the fiber cloth. The high temperature of the hot cutting blade ensures a clean cut without burrs. When the hot cutting blade 53 moves upward, the cleaning component 56 removes the burnt fibers adhering to the outer wall of the hot cutting blade 53. This prevents the adhering fibers from affecting the subsequent cutting work of the hot cutting blade 53, thus ensuring that the hot cutting blade 53 can continue to perform efficient cutting work.

[0030] In addition, since the hot cutting blade 53 moves up and down, it can periodically cut the fiber cloth, thus achieving quantitative length cutting of the fiber cloth. By adjusting the rotation of the output shaft of the first motor 3, the conveying speed of the conveying roller 2 on the fiber cloth can be adjusted, thereby adjusting the single-segment cutting length of the fiber cloth to meet the actual cutting requirements of different lengths.

[0031] Furthermore, the outer side of the mounting base 4 is threaded with a positioning bolt (not marked in the attached drawing), which is used to fix the mounting base 4 to the worktable 1. The positioning bolt can fix the mounting base 4 to the worktable 1, and the mounting base 4 can also be disassembled by removing the positioning bolt, thus facilitating the maintenance of the entire cutting mechanism.

[0032] Furthermore, the drive component 55 includes a second motor 551 fixedly mounted on the top of the mounting bracket 51. The output shaft of the second motor 551 is fixedly connected to an eccentric wheel 552. The outer edge of the eccentric wheel 552 is rotatably connected to a connecting rod 553 via a pin. The end of the connecting rod 553 away from the eccentric wheel 552 is hinged to the top end of the movable rod 52.

[0033] By starting the second motor 551, the eccentric wheel 552 is driven to rotate, which causes the connecting rod 553 to drive the movable rod 52 to slide up and down, so that the hot cutting blade 53 can move up and down. When the hot cutting blade 53 moves downward and cooperates with the blade groove 7, the hot cutting blade 53 can cut the fiber cloth.

[0034] Furthermore, the cleaning component 56 includes two mounting plates 561 symmetrically distributed along the center line of the mounting frame 51. The two mounting plates 561 are fixedly connected to both ends of the inner side of the mounting frame 51. Fixing seats 562 are fixedly connected to the outer sides of the two mounting plates 561. Rotating rods 563 are rotatably connected to the inner sides of the two fixing seats 562 via pins. Scrapers 564 are hinged to the bottom ends of the two rotating rods 563. The hot cutting blade 53 has a structure that is wider at the top and narrower at the bottom. The distance between the two scrapers 564 is greater than the thickness of the narrow part of the hot cutting blade 53 and less than the thickness of the wide part of the hot cutting blade 53. Torsion springs 565 are sleeved on the pins of the two rotating rods 563. One end of the two torsion springs 565 is welded to the corresponding fixing seat 562, and the other end of the two torsion springs 565 is welded to the corresponding rotating rod 563. A pusher 566 is provided at the bottom end of the movable rod 52, which drives the two rotating rods 563 to rotate in opposite directions by sliding with the movable rod 52.

[0035] During the reciprocating motion of the hot cutting blade 53, it will come into contact with and slide relative to the scraper 564, so that the scraper 564 scrapes off the charred fibers attached to the outer wall of the hot cutting blade 53. At the same time, under the torsional elastic force of the torsion spring 565, the scraper 564 and the hot cutting blade 53 remain in close contact, which can further improve the cleaning effect on the outer wall of the hot cutting blade 53.

[0036] The pusher 566 includes a fixed ring 5661 fixedly connected to the movable rod 52. Both ends of the fixed ring 5661 are fixedly connected to protrusions 5662. The bottom ends of both mounting plates 561 are slidably connected to sliding rods 5663 that penetrate the mounting plates 561. One end of each sliding rod 5663 is fixedly connected to an arc-shaped top block 5664. The two protrusions 5662 can cooperate with the movement of the fixed ring 5661 to abut against the corresponding arc-shaped top block 5664. During the upward movement of the hot cutting blade 53, the hot cutting... When the top surface of the blade 53 contacts the scraper 564, the protrusion 5662 and the arc-shaped top block 5664 are in contact. The other end of each of the two slide rods 5663 is hinged with a push rod 5665. One end of each push rod 5665 is connected to the middle of the corresponding rotating rod 563. Each of the two slide rods 5663 is fitted with a return spring 5666. One end of each return spring 5666 contacts the corresponding arc-shaped top block 5664, and the other end of each return spring 5666 contacts the corresponding mounting plate 561.

[0037] Furthermore, a correction mechanism 6 is provided at both ends of the inner side of the workbench 1. The correction mechanism 6 includes a fixed plate 61 fixedly connected to the inner side of the workbench 1. Elastic elements 62 are fixedly connected to both ends of the fixed plate 61. A limiting plate 63, which is parallel to the fixed plate 61, is fixedly connected to the same end of the two elastic elements 62. The limiting plate 63 can abut against the fiber cloth. Under the action of the elastic elements 62, the limiting plate 63 applies a pushing force to the fiber cloth, so that the fiber cloth is always conveyed in the correct direction, effectively avoiding the problem of the fiber cloth running off-center and affecting the cutting effect.

[0038] Working principle: By starting the second motor 551, the eccentric wheel 552 is driven to rotate, which causes the connecting rod 553 to drive the movable rod 52 to slide up and down, so that the hot cutting blade 53 can move up and down. When the hot cutting blade 53 moves downward and cooperates with the blade groove 7, the hot cutting blade 53 can cut the fiber cloth. The high temperature of the hot cutting blade can make the cut neat and without burrs.

[0039] During the upward movement of the hot cutting blade 53, the rotating rod 563 drives the fixed ring 5661 to move upward. When the hot cutting blade 53 moves to the bottom position of the scraper 564, the two protrusions 5662 abut against the arc-shaped top block 5664, causing the arc-shaped top block 5664 to be squeezed and move in opposite directions. This causes the two sliding rods 5663 to move in opposite directions and drives the push rod 5665 to apply a pushing force to the corresponding rotating rod 563. At this time, the return spring 5666 is compressed and accumulates potential energy, causing the rotating rods 563 to rotate in opposite directions and causing the two scrapers 564 to open. At this time, the torsion spring 565 is contracted and accumulates potential energy, allowing the top of the hot cutting blade 53 to move smoothly to the bottom position. Between the two scrapers 564, the protrusion 5662 disengages from the arc-shaped top block 5664, and the return spring 5666 releases potential energy, causing the two sliding rods 5663 to slide in opposite directions. At the same time, the torsion spring 565 causes the two rotating rods 563 to rotate in opposite directions, and the two scrapers 564 move in opposite directions and abut against the outer wall of the hot cutting blade 53. As the hot cutting blade 53 continues to move upward, it slides and rubs against the two scrapers 564, thereby cleaning the charred fibers attached to the outer wall of the hot cutting blade 53. This can prevent the attached fibers from affecting the subsequent cutting work of the hot cutting blade 53, thus ensuring that the hot cutting blade 53 can continue to perform efficient cutting work.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
