In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] like Figure 1-4 As shown, the cardboard box processing groove and slotting machine described in this embodiment includes a machine body 1 and a motor-driven lifting beam 2 mounted on the machine body 1. Specifically, a motor-driven turntable 3 is installed inside the machine body 1, and an eccentric shaft 4 is installed on the turntable 3. Slider 5s are respectively installed at both ends of the beam 2. A slide rail 6 that cooperates with the slider 5 is installed on the machine body 1. A rotating shaft 7 is fixed on the slider 5. A connecting rod 8 is installed between the rotating shaft 7 and the eccentric shaft 4. Both ends of the connecting rod 8 are bushings. When the turntable 3 rotates, the presence of the eccentric shaft 4 drives the beam 2 to move up and down repeatedly.

[0021] A grooving knife 9 and a crimping knife 10 are provided on the crossbeam 2. The crimping knife 10 is detachably mounted on the crossbeam 2. Specifically, a first lap 11 is provided between the crimping knife 10 and the crossbeam 2. Above the first lap 11, multiple auxiliary positioning screws 12 are evenly distributed along the left and right directions on the crimping knife 10. Specifically, the crimping knife 10 is provided with countersunk screw holes. The auxiliary positioning screws 12 are hexagonal socket head cap screws with the nuts located inside the countersunk screw holes, so they will not interfere with the grooving knife 9. The tail end of the auxiliary positioning screw 12 abuts against the crossbeam 2 to position the crimping knife 10 and prevent the crimping knife 10 from falling off. The grooving knife 9 is slidable left and right. Specifically, the grooving knife 9 is provided with a slot 13 that mates with the crimping knife 10. The grooving knife 9 overlaps the top surface of the crimping knife 10. Preferably, an overlap edge 14 is also provided between the crimping knife 10 and the grooving knife 9 to increase the assembly stability of the grooving knife 9 and the crimping knife 10. The crossbeam 2 can also be provided with multiple sliding left and right abutment blocks 15. Specifically, a second overlap edge 16 is provided between the abutment block 15 and the crossbeam 2. The abutment block 15 is U-shaped, and a grooving knife abutment screw 17 is screwed onto the abutment block 15. A handle 18 is fixed on one end of the grooving knife abutment screw 17 located outside the abutment block 15.

[0022] The left and right ends of the grooving cutter 9 are detachably equipped with cardboard auxiliary positioning mechanisms. These mechanisms include a vertically arranged sleeve 19, a connecting plate 20 fixed to the sleeve 19, a telescopic rod 21 coaxially mounted on the sleeve 19, an adjusting block 22 screwed into the sleeve 19, an upper rod 23 coaxially fixed to the top surface of the adjusting block 22, and a lower rod 24 coaxially fixed to the bottom surface of the adjusting block 22. The connecting plate 20 is detachably mounted on the grooving cutter 9 via bolts; the telescopic rod 21... The upper part is provided with a paper pressing block 25 and an insertion hole 26 that cooperates with the lower rod 24. A compression spring is sleeved on the lower rod 24 between the telescopic rod 21 and the adjusting block 22. The upper end of the upper rod 23 extends to the outside of the sleeve 19 and is fixed with a screw head 27, which is a nut or a handwheel. By screwing the screw head 27 and the upper rod 23, the adjusting block 22 can be driven to rise or fall, thereby adjusting the initial pressure of the compression spring, that is, adjusting the initial downward pressure of the telescopic rod 21, so as to ensure the positioning of the paperboard while avoiding damage to the paperboard.

[0023] When the crossbeam 2 drives the grooving knife 9 to press down, the cardboard auxiliary positioning mechanism moves down together, and the pressure block 25 contacts the cardboard before the grooving knife 9. Preferably, the pressure block 25 is a rubber block. The pressure block 25 can position the cardboard first to prevent the cardboard from shifting and ensure accurate cardboard processing. The grooving knife 9 continues to move down, and the telescopic rod 21 retracts into the sleeve 19. The grooving knife 9 and the creasing knife 10 contact the cardboard one after the other. The creasing knife 10 completes the creasing. When the grooving knife 9 rises, the telescopic rod 21 extends under the action of the compression spring. The upper end of the telescopic rod 21 is integrally provided with an anti-detachment limiting head 28.

[0024] The working principle of this embodiment is as follows:

[0025] The cardboard to be processed is conveyed to the processing platform on machine body 1. The crossbeam 2 descends, and the grooving knife 9 first contacts the cardboard to complete grooving. After the grooving knife 9 continues to descend, the creasing knife 10 contacts the cardboard to complete creasing. After creasing is completed, the crossbeam 2 rises, the processed cardboard is removed, and the next cardboard to be processed enters, and this cycle continues. When the position of the grooving knife 9 needs to be adjusted, the grooving knife clamping screw 17 is loosened by the handle 18, and the position of the grooving knife 9 is adjusted left and right. After adjustment, the clamping block 15 is also slid to correspond to each position of the grooving knife 9, and the grooving is completed by tightening the handle 18. The slotting knife clamping screw 17 clamps the slotting knife 9, and the slotting knife clamping screw 17 and the crossbeam 2 together clamp the slotting knife 9. In addition, the crimping knife 10 can be disassembled and assembled by tightening and loosening the slotting knife clamping screw and the auxiliary positioning set screw 12. Compared with the prior art, this embodiment can quickly adjust the position of the slotting knife 9 and disassemble and assemble the crimping knife to meet production requirements. The entire adjustment process does not require tools and is simple to operate. After the adjustment is completed, the positions of the slotting knife 9 and the crimping knife 10 are firmly fixed, the production is stable, and it has strong practicality.

[0026] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
