[0061] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0062] A cardboard slotting machine, comprising: a bottom plate 1, a conveyor belt 204, a driving plate 205, a first placing plate 3, and a second placing plate 302;

[0063] Specifically, the base plate 1 is a rectangular cube, and four supporting legs 101 are fixedly installed on the bottom surface of the base plate 1 near the four corners, and the top surface of the base plate 1 is partially concave to form a conveying groove 2; a conveyor belt 204 is rotatably arranged in the conveying groove 2, and specifically, two rotating shafts 201 are rotatably arranged in the conveying groove 2, and one of the rotating shafts 201 is rotatably connected to a transmission motor 202; four conveying wheels 203 are evenly distributed on the rotating shaft 201, and conveyor belts 204 are sleeved on the conveying wheels 203 corresponding to the two rotating shafts 201, and the conveying surface of the conveyor belt 204 is flush with the top surface of the base plate 1; two evenly distributed driving plates 205 are fixedly installed on each conveyor belt 204.

[0064] The first placement plate 3 is fixedly mounted on the bottom plate 1, and the bottom surface of the first placement plate 3 is concave to form a first through groove 301; the second placement plate 302 is movably arranged on one side of the first placement plate 3, and the bottom surface of the second placement plate 302 is concave to form a second through groove 303;

[0065] More specifically, the surface portions of the bottom plate 1 located on both sides of the conveying groove 2 are concave to form two oppositely arranged first moving grooves 304, and the bottom surface portions of the first moving grooves 304 are protruding and movably arranged in the second moving groove 701; two oppositely arranged threaded cylinders 305 are fixedly installed on the second placement plate 302, and two oppositely arranged limiting screws 306 are rotatably arranged on the first placement plate 3, and the limiting screws 306 are threadedly connected with the threaded cylinders 305; a synchronous wheel 307 is fixedly installed on one end of the limiting screw 306 away from the second placement plate 302, and a synchronous belt 308 is provided on the outer sleeve of the synchronous wheel 307 on the two limiting screws 306, and a limiting knob 309 is fixedly connected to one of the synchronous wheels 307;

[0066] Rotate the limit knob 309. Due to the setting of the synchronous belt 308, the two limit screws 306 can rotate synchronously.
