DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-5 As shown, a fiber fabric lace cutting device of the utility model comprises a processing table 1, a reeling roller 11 is arranged on the left side of the processing table 1, a reeling roller 12 is arranged on the right side of the processing table 1, a U-shaped frame 13 is fixed in the middle of the processing table 1, and cutting mechanisms are arranged on both the front and rear sides of the U-shaped frame 13;

[0026] The cutting mechanism includes a housing 2 provided with a U-shaped frame 13, a first motor 21 is installed in the housing 2, a transmission shaft 22 is fixed to the output shaft of the first motor 21, a connecting seat 23 is connected to the end of the transmission shaft 22, a rolling cutter 24 is connected to the connecting seat 23, and a connecting assembly is provided between the connecting seat 23 and the rolling cutter 24;

[0027] The connecting assembly includes a connecting groove 231 provided on the connecting seat 23, a connecting block 241 slidably provided in the connecting groove 231 is fixed to the rolling cutter 24, a plurality of sliding grooves 232 are provided on the connecting seat 23, a locking block 233 is slidably provided in the sliding groove 232, a locking groove 242 matching the locking block 233 is provided on the connecting block 241, a bevel is processed on one side of the locking block 233, a first spring 234 is provided between the locking block 233 and the sliding groove 232, a movable groove 221 is provided in the middle of the transmission shaft 22, a movable block 222 is slidably provided in the movable groove 221, the movable block 222 and the locking block 233 are connected by a pull wire 223, and a toggle plate 224 is connected to the outer side of the movable block 222.

[0028] In the initial state, the connecting block 241 is located in the connecting groove 231, and the locking block 233 is located in the locking groove 242 under the elastic force of the first spring 234, so as to keep the rolling cutter 24 and the connecting seat 23 stably connected;

[0029] When the device is working, the fiber fabric is placed on the unwinding roller 11, and the fabric passes under the rolling cutter 24, and then is pulled onto the winding roller 12, and the first motor 21 is started, and the output shaft of the first motor 21 rotates to drive the rolling cutter 24 to rotate, and the lace is cut at both ends of the fabric. The fabric is continuously wound by the winding roller 12, so that the lace cutting of the fabric can be carried out continuously;

[0030] When cutting laces of different shapes on the fabric, the rolling cutter 24 needs to be replaced. The staff only needs to slide the toggle plate 224 by hand to drive the movable block 222 to slide in the movable groove 221. The locking blocks 233 in the multiple slide grooves 232 can be pulled synchronously by the pull wire 223 to move, so that the locking blocks 233 withdraw from the locking grooves 242 and release the fixation. The staff can then remove the rolling cutter 24, which is easy to operate. When installing a new rolling cutter 24, since the locking block 233 is processed with an inclined surface, it is only necessary to slide the connecting block 241 into the connecting groove 231, and push the locking block 233 into the slide groove 232 until the locking groove 242 is aligned with the locking block 233. The elastic force of the first spring 234 will push the locking block 233 into the locking groove 242, so that the rolling cutter 24 is fixed, and the installation is convenient.

[0031] Both sides of the U-shaped frame 13 are provided with vertical grooves 131, the housing 2 is slidably arranged in the vertical grooves 131, the outer ends of the two housings 2 are fixed with L-shaped connecting plates 3, the upper end of the U-shaped frame 13 is fixed with a mounting frame 31, the upper end of the mounting frame 31 is installed with a cylinder 32, and the output shaft of the cylinder 32 is connected to the two L-shaped connecting plates 3;

[0032] The output shaft of the cylinder 32 is fixed with a rectangular shell 33, and the two L-shaped connecting plates 3 are slidably extended into the rectangular shell 33 and connected with a slide plate 34. A rotating shaft 35 is rotatably assembled in the rectangular shell 33. The front and rear sides of the rotating shaft 35 are processed with threaded sections 36. The threaded rotation directions of the two threaded sections 36 are opposite, and the two slide plates 34 are threadedly connected with the two threaded sections 36 respectively. A second motor 37 is installed on the outside of the rectangular shell 33, and the output shaft of the second motor 37 is connected to the rotating shaft 35.

[0033] The cylinder 32 can drive the rectangular shell 33 to move upward, that is, the L-shaped connecting plate 3 drives the rolling cutter 24 to move upward as a whole, so that the rolling cutter 24 can be away from the surface of the processing table 1, so that the cloth can pass under the rolling cutter 24;

[0034] The second motor 37 drives the rotating shaft 35 to rotate. Since the slide plate 34 fixed by the L-shaped connecting plate 3 is threadedly connected to the threaded section 36, and the two threaded sections 36 of the rotating shaft 35 have opposite thread rotation directions, the two L-shaped connecting plates 3 can be driven to move relative to or away from each other, thereby adjusting the distance between the two rolling cutters 24, so that it can be adjusted according to the width of different fabrics, thereby improving practicality.

[0035] A stabilizing pulley 4 is provided between the L-shaped connecting plate 3 and the U-shaped frame 13;
