[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Please refer to Figures 1-5The utility model provides a technical solution: a carton slotting machine, including a machine body 1, a slotting knife seat 2, a conveyor belt 3, and a limiting wheel 5. A square slot 11 is opened through the top of the machine body 1, and the slotting knife seat 2 extends through the square slot 11 to the inside of the machine body 1. Symmetrical rotating wheels 4 are set on both sides of the conveyor belt 3. A rotating rod motor 32 is fixedly installed on one side of the inner wall of the machine body 1. Rotating rods 31 are symmetrically installed on both sides of the inner wall of the machine body 1. The output end of the rotating rod motor 32 is fixedly connected to the end of the rotating rod 31 on the same side. The rotating rod 31 A clamping groove 44 is provided at equal intervals through the upper portion, and multiple groups of rotating wheels 4 can be detachably mounted on the two groups of rotating rods 31. A sliding groove 41 is provided at both ends of the rotating wheel 4, and a semicircular protrusion 42 is slidably mounted inside the sliding groove 41. A thread 423 is provided on one side of the semicircular protrusion 42. A clamping block 421 is fixedly mounted on the inner wall of the semicircular protrusion 42. The clamping block 421 on the inner side of the semicircular protrusion 42 is clamped in the clamping groove 44. A thread 423 is provided on one side of the semicircular protrusion 42, and a bolt 43 is threadedly connected to the outer side of the thread 423.

[0024] The rotating rod motor 32 is started, and the rotating rod 31 is driven to rotate through the output end. The rotating wheel 4 mounted on the rotating rod 31 rotates along with the rotating rod 31, driving the rotation of the conveyor belt 3. The cardboard is conveyed to the inside of the machine body 1 through the conveyor belt 3, and then moves to the limiting wheel 5. The limiting wheel 5 and the conveyor belt 3 cooperate to squeeze and limit the cardboard. Then, it moves to the blade 23, and the blade 23 cuts the cardboard to form a groove.

The semi-circular convex block 42 is slidably connected to the chute 41 through the slider 422, enabling the semi-circular convex block 42 to move freely within the chute 41. When the two semi-circular convex blocks 42 are moved so that the clamping block 421 is clamped in the clamping groove 44, preliminary fixation is performed, and then the bolt 43 is tightened to make the two semi-circular convex blocks 42 fit tightly, so that the two groups of semi-circular convex blocks 42 are completely fixed on the rotating rod 31.

[0030] Among them, the conveyor belt 3 is fixedly sleeved on the two side rotating wheels 4, and the limiting wheel 5 has a clearance fit with the upper surface of the conveyor belt 3.

[0031] Working principle: When in use, start the rotating rod motor 32, drive the rotating rod 31 to rotate through the output end. The rotating wheel 4 sleeved on the rotating rod 31 rotates along with the rotating rod 31, driving the rotation of the conveyor belt 3. The cardboard is conveyed into the machine body 1 through the conveyor belt 3, and then displaced to the limiting wheel 5. The cardboard is squeezed and limited through the cooperation of the limiting wheel 5 and the conveyor belt 3, and then displaced to the cutting edge 23, and the cardboard is grooved through the cutting of the cutting edge 23;

[0032] When the grooving position needs to be adjusted, first start the lead screw motor 22. The lead screw 21 rotates, and the grooving tool holder 2 translates along with the rotation of the lead screw 21. When it moves to the position where grooving is required, turn off the lead screw motor 22. Then unscrew the bolt 43, and then move the two pairs of semi-circular convex blocks 42 clamped on the rotating rod 31 to the edges of the rotating wheel 4 respectively. At this time, the rotating wheel 4 is in a movable state. Then adjust the positions of the three groups of conveyor belts 3 according to the position of the grooving tool holder 2 to make the conveyor belt 3 avoid the bottom of the cutting edge 23, and then perform grooving.
