[0034] See also Figure 1 and Figure 3 , a cardboard slotting machine for packaging box production, comprising:

[0035] A slotted body 1; and

[0036] A mounting frame 2, which is arranged inside the slotted body 1, and the mounting frame 2 is composed of two horizontal plates, and a rectangular groove is arranged on one side of the horizontal plate close to the rotating shaft 3, and there is a gap between the two horizontal plates;

[0037] The rotating shaft 3 includes a shaft body 31 and a transverse groove 32, and is disposed between the mounting frames 2. The shaft body 31 is disposed inside the slotted body 1, and the transverse groove 32 is disposed on the outer surface of the shaft body 31;

[0038] Based on the above, the slotting body 1 is a prior art and does not belong to the technical features protected by this technical solution. Therefore, its specific structure and principle are not described in detail here. The slotting body 1 here plays a role in controlling the rotation of the rotating shaft 3. The setting of the mounting frame 2, on the one hand, has a limiting effect on the moving mechanism, so that it can only move along the direction of the rectangular groove. On the other hand, the moving mechanism cooperates with the nut and can be connected to the mounting frame 2 to achieve the effect of fixing the moving mechanism.

[0039] like Figure 1 , Figure 2 , Figure 4-Figure 6 as well as Fig. 9 As shown, the roller includes a first roller block 4, a cutter 5, a main sphere 6, a fixing block 7 and a second roller block 11, and is divided into a cutting wheel and a bottom wheel, wherein:

[0040] The first roller block 4 includes a first wheel body 41, which is arranged outside the shaft body 31, and has first spherical grooves 42 and first through holes 43 on both sides of the first wheel body 41, and a mounting groove 44 and a threaded blind hole 45 on the outer surface of the first wheel body 41, and the main ball 6 is arranged between the second spherical groove 72 and the first spherical groove 42;

[0041] A cutter 5 is arranged on the outer surface of the first roller block 4 by means of screws, the cutter 5 comprises an arc-shaped plate 51, a mounting hole 54 is arranged on the outer surface of the arc-shaped plate 51, the screw passes through the mounting hole 54 and is threadedly connected with the threaded blind hole 45, a positioning block 52 is arranged on one side of the arc-shaped plate 51 close to the first roller block 4, the positioning block 52 extends to the inside of the mounting groove 44, and a cutter body 53 is arranged on the outer surface of the arc-shaped plate 51;

[0042] The main sphere 6 is disposed on both sides of the first roller block 4 and the second roller block 11 and extends to the inside of the transverse groove 32;

[0043] The fixing block 7 comprises a block body 71, and a second spherical groove 72 and a nut mounting hole 73 are respectively provided on two sides of the block body 71;

[0044] The second roller block 11 comprises a second wheel body 111, and both sides of the second roller block 11 are provided with a fourth spherical groove 112 and a second through hole 113, and the main sphere 6 is provided between the fourth spherical groove 112 and the second spherical groove 72;

[0045] Based on the above, the first roller block 4, the tool 5, the main sphere 6 and the fixed block 7 cooperate with each other through screws and nuts to form a cutting wheel, and the second roller block 11, the main sphere 6 and the fixed block 7 cooperate with each other through screws and nuts to form a bottom wheel. The cutting wheel is sleeved to the outside of the upper rotating shaft 3, and the bottom wheel is sleeved to the lower rotating wheel 3. At this time, the cutting wheel plays a cutting role, and the bottom wheel plays an auxiliary transmission role. In the above process, the main sphere 6 cooperates with the transverse groove 32, so that the rotating shaft 3 can drive the cutting wheel and the bottom wheel to rotate, and enable the cutting wheel and the bottom wheel to move along the direction of the transverse groove 32.

[0046] like Figure 2 , Figure 7 as well as Figure 8 As shown, the moving mechanism includes a cover plate 8, a small sphere 9, a limiting block 10 and a force plate 12, and is connected to the mounting frame 2 through a nut;

[0047] The cover plate 8 comprises an annular block 81, and a spherical through hole 82 and a hollow cylinder 83 are provided on the surface of the annular block 81;

[0048] The limiting block 10 comprises a top block 101, a connecting hole 102 is provided on one side of the top block 101, a threaded column 103 is provided on the side of the top block 101 away from the rotating shaft 3, a mounting ring 104 is provided on the side of the top block 101 close to the rotating shaft 3, a third spherical groove 105 and a threaded hole 106 are provided on the surface of the mounting ring 104, the small sphere 9 is provided between the third spherical groove 105 and the spherical through hole 82, the force plate 12 is sleeved on the outside of the threaded column 103, and is connected to the mounting frame 2 through a nut;

[0049] Based on the above, the moving mechanism plays a role in pushing the roller to move, wherein the small ball 9 is arranged between the limiting block 10 and the cover plate 8, a part of the small ball 9 passes through the spherical through hole 82 and then extends out, and the extended part contacts the surface of the fixed block 7, so that the roller can rotate with the rotating shaft 3, and the limiting block 10 is arranged on both sides of the roller, such as Figure 1 and Figure 2 As shown, at this time, the roller can move together with the limiting block 10, and the limiting block 10 is fixed to the mounting frame 2 under the cooperation of the force plate 12 and the nut.

[0050] In actual use, the embodiment controls the rotation of the rotating shaft 3 through the slotting body 1, and the rotating shaft 3 can drive the roller to rotate together. Due to the setting of the moving mechanism, that is, the small ball 9 inside the moving mechanism, the roller will not be hindered by the moving mechanism when rotating, and will not be severely worn due to excessive friction.

[0051] The main ball 6 and the transverse groove 32 inside the roller cooperate with each other, so that the roller can rotate along with the rotating shaft 3, and the roller can move along the transverse groove 32, and the rotation of the roller will not be affected during the movement. The main ball 6 makes the movement process smoother;

[0052] Through the arrangement of the mounting frame 2 and the force-bearing plate 12, the position adjustment and fixation of the moving mechanism are achieved. By loosening the nut and moving the moving mechanism laterally, the moving mechanism drives the force-bearing plate 12 to move along the gap inside the mounting frame 2. After the movement, the nut is tightened again to fix the moving mechanism. In this process, the moving mechanism drives the roller to move together to achieve the effect of changing the position of the tool 5, so that the position and spacing of the slots can also be adjusted.

[0053] Compared with traditional slotting machines, this slotting machine has the ability to adjust the position and spacing of the cutters, which not only has higher adjustment efficiency but also has more flexibility.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
