Description

Technical Field

[0001] The present invention relates to the technical field of quilting machines, and in particular to a grabbing and stacking device for a quilting machine. Background Art

[0002] A quilting machine is a sewing device specifically designed for quilting the edges of fabric. Quilting refers to folding the edges of fabric before sewing to prevent them from unraveling and also beautify the edges of clothing. Quilting machines typically use different quilting feet and stitches to accommodate different types and thicknesses of fabric. They are widely used in home sewing, clothing making, home textiles, and other fields. This machine is easy to operate and produces effective results, making it a commonly used piece of equipment in the sewing process. When a quilting machine is in use, it is necessary to load the cloth layer material. In traditional cloth layer material loading operations, most of the loading is done manually, and the cloth layer material is manually taken to stack and position. Among them, the cloth layer material is mostly cylindrical material, and the cloth layer material at the end of the cylindrical material needs to be cut at an appropriate distance. After cutting, it is manually taken, stacked, and positioned, and finally, quilting is performed. It is time-consuming and labor-intensive, which reduces the quilting efficiency of the entire quilting machine.

[0029] Working principle: When in use, the first motor 323 is controlled to start and drive the first worm 322 to drive the first worm wheel 321 to rotate, thereby driving the flip shaft 32 to rotate, and then driving the grabbing mechanisms 4 on both sides to flip synchronously, so that the grabbing mechanisms 4 on both sides are in a vertical state; Subsequently, the fifth motor 11 is controlled to start driving the threaded rod 14 to rotate, driving the connecting frame 13 to slide in translation, thereby driving the two first linear slides 121 to slide in translation on the first linear guide rail 12, driving the connecting longitudinal frame 2, the distance adjustment mechanism 3 and the grabbing mechanism 4 to slide in translation, and moving the two grabbing mechanisms 4 to the ends of the cylindrical cloth layer material; Subsequently, the spacing of each U-shaped positioning frame 45 is adjusted according to the width of the material; by controlling the fourth motor 4710 to start, the fourth worm 479 drives the fourth worm gear 478 to rotate, thereby driving the second double-headed screw 476 to rotate, driving the drive blocks 477 on both sides and the second shaft 473 corresponding to the middle position to move backwards, cooperating with the first connecting rod 471 and the second connecting rod 472 to cross-rotate and connect, driving multiple first shafts 47 to move toward each other synchronously with the same spacing, thereby driving multiple second linear slides 43 to move toward each other synchronously with the same spacing, thereby reducing the spacing of each U-shaped positioning frame 45; conversely, by controlling the second double-headed screw 476 to rotate in the opposite direction, driving the drive blocks 477 on both sides and the second shaft 473 corresponding to the middle position to move toward each other, cooperating with the first connecting rod 471 and the second connecting rod 472 to cross-rotate and connect, driving multiple first shafts 47 to move backwards synchronously with the same spacing, thereby driving multiple second linear slides 43 to move backwards synchronously with the same spacing, thereby increasing the spacing of each U-shaped positioning frame 45, so as to adapt to multi-point clamping and positioning of materials of different widths; Subsequently, the third motor 464 in the bottom position grabbing mechanism 4 is controlled to drive the third worm 463 to rotate, thereby driving the third worm gear 462 and the male drive shaft 46 to rotate, and then driving the multiple rotating cylinders 442 to rotate synchronously, thereby controlling the multiple rotating rods 441 to rotate synchronously at the bottom of the rotating frame 44, and synchronously adjusting the clamping and positioning angles of the multiple U-shaped positioning frames 45, so that the multiple U-shaped positioning frames 45 in the bottom position grabbing mechanism 4 correspond to the ends of the cylindrical cloth layer material, and continue to translate the connecting vertical frame 2, the distance adjustment mechanism 3 and the grabbing mechanism 4, so that the cloth layer material at the end of the cylindrical cloth layer material is clamped into the multiple U-shaped positioning frames 45 in the bottom position grabbing mechanism 4; Subsequently, the multiple telescopic rods 452 are controlled to open and drive the positioning block 451 to slide in the U-shaped positioning frame 45 to clamp the material between the U-shaped positioning frame 45 and the positioning block 451; Subsequently, the connecting vertical frame 2, the distance adjustment mechanism 3 and the grabbing mechanism 4 are controlled to slide in opposite directions, pulling the cloth material until the cloth material is of the required length and cutting it. Simultaneously, the grabbing mechanisms 4 on both sides are flipped over, and the grabbing mechanisms 4 that were originally holding the material at the bottom position are flipped over to the top position. At the same time, the multiple U-shaped positioning frames 45 are adjusted to a vertical state. At this time, the cut end of the clamped material falls freely to the position of the grabbing mechanism 4 on the other side. Subsequently, the second motor 353 is controlled to be turned on to drive the second worm 352 to drive the second worm gear 351 to rotate, thereby driving the first double-headed screw 35 to rotate, driving the grabbing mechanisms 4 on both sides to slide synchronously toward each other, reducing the distance between the grabbing mechanisms 4 on both sides, and the distance-adjusting sliding frame 34 slides on the corresponding guide shaft 33 until the cut end of the clamped material is stuck in the multiple U-shaped positioning frames 45 at the bottom position. Subsequently, the multiple telescopic rods 452 at the bottom position are controlled to be turned on to drive the positioning block 451 to slide in the U-shaped positioning frame 45, clamping the material between the U-shaped positioning frame 45 and the positioning block 451, thereby clamping both ends of the material; After clamping is completed, the grabbing mechanisms 4 on both sides are controlled to flip again to make the material horizontal. At this time, the connecting longitudinal frame 2, the distance adjustment mechanism 3 and the grabbing mechanism 4 are controlled to slide horizontally, and the material is moved to the quilting machine position for automatic stacking, thereby improving the quilting efficiency of the entire quilting machine.
