As shown in fig. 7, the two opposite sides of the sliding block 721 are fixed with the limiting blocks 722, the two opposite sides of the second sliding groove 711 are provided with the limiting grooves 712, the limiting grooves 712 extend in the vertical direction, and the limiting blocks 722 are slidably mounted in the limiting grooves 712, so as to guide the sliding block 721;
the side wall of the limiting block 722 is provided with a plurality of rolling balls 723 in a rolling manner, the rolling balls 723 are uniformly distributed, and the rolling balls 723 are abutted against the inner side wall of the limiting groove 712, so that the sliding block 721 can slide more smoothly.
The implementation principle of the embodiment is as follows: when the label related to the invention is printed, the roll-shaped label paper passes through the paper feeding device 4 and is conveyed to a feed inlet of the printing device 5 through a conveying roller, the label paper is driven by the printing wheel 52, a printing layer of the label body 2 is coated with white color through the dye printing seat 53, then the label paper is dried through the UV device 54 and is conveyed to the gloss oil printing seat, and gloss oil is coated on one side of the label body 2, which is far away from the base paper 1; then the label body 2 is conveyed to a positive die cutting seat 6 through a conveying roller to be die-cut, and then the label body is conveyed to a negative die cutting seat 7 to be die-cut on the base paper 1; the label paper is rolled by a paper collecting device 8 after being subjected to positive and negative die cutting to finish printing;
when the beginning part of a batch of labels passes between the first upper die pressing roller 62 and the first lower die pressing roller 63, and the position to be cut of the label body 2 is found to be inconsistent with the position of the first die cutting blade 621, the first screw 65 is rotated by the first turntable 651, the pressing roller 66 is separated from the first upper die pressing roller 62, then the first hydraulic cylinder 687 is started, the first upper die pressing roller 62 is tilted until the first ratchet 683 is contacted with the first rack 685, the piston of the first hydraulic cylinder 687 is continuously stretched, the rotation of the first ratchet 683 drives the first upper die pressing roller 62 to rotate, then the first ratchet 683 is separated from the first rack 685, and the steps are repeated until the adjustment is consistent, so that the adjustment for the die cutting seat 6 is completed; when the beginning part of a batch of labels passes through the position between the second upper die pressing roller 72 and the second lower die pressing roller 73, and the position of the base paper 1 to be cut is found to be inconsistent with the position of the second die cutting blade 731, the second screw 74 is rotated through the second turntable 741, the second upper die pressing roller 72 is pulled to be away from the second lower die pressing roller 73, then the second hydraulic cylinder 757 is started, so that the second lower die pressing roller 73 is tilted until the second ratchet 753 is in contact with the second rack 755, the piston of the second hydraulic cylinder 757 continues to be stretched, so that the second ratchet 753 rotates to drive the second upper die pressing roller 72 to rotate, then the second ratchet 753 is separated from the second rack 755, and the steps are repeated until the position is adjusted to be consistent, so that the adjustment of the reverse die cutting seat 7 is completed.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
