[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] As attached Figure 1 To be continued Figure 5 As shown: A cardboard cutting machine for packaging boxes includes a base 1, a conveyor belt 2 mounted above the base 1, and a cutting mechanism 3 for cutting cardboard above the conveyor belt 2. The cutting mechanism 3 includes a U-shaped plate 301 mounted above the conveyor belt 2, and a third electric push rod 302 embedded in the top of the U-shaped plate 301. A cutter 303 is fixedly connected to the output end of the third electric push rod 302. The cardboard can be conveyed by the conveyor belt 2. When it is conveyed above the cutter 303, the third electric push rod 302 is controlled to extend and push the cutter 303 to descend, and the cutter 303 will complete the cutting of the cardboard. A support plate 5 is installed inside the conveyor belt 2 to support the conveyor belt 2 and prevent the conveyor belt 2 from sinking, thereby forming a support for the conveyor belt 2 and the cardboard, and thus ensuring the normal operation of the cutting work.

[0027] A feeding assembly 4 is provided above the base 1. The feeding assembly 4 includes a loading box 401 fixedly connected to the base 1. A set of carrier plates 402 flush with the conveyor belt 2 are installed on the inner wall of the loading box 401. A through groove 403 is opened on one side of the loading box 401. The size of the through groove 403 is slightly smaller than that of the cardboard. A first electric push rod 404 is fixedly connected to one side of the loading box 401. An L-shaped push plate 405 is fixedly connected to the telescopic end of the first electric push rod 404, and the outer surface of the bottom end of the L-shaped push plate 405 is slidably connected to the inner wall of the through groove 403. By controlling the first electric push rod 404 to retract, the L-shaped push plate 405 can be moved. The L-shaped push plate 405 will push the bottom cardboard placed on the carrier plate 402 to move it above the conveyor belt 2. After a single cardboard moves above the conveyor belt 2, controlling the first electric push rod 404 to extend will cause the L-shaped push plate 405 to reset, and the stacked cardboard will fall back above the carrier plate 402. Then, by controlling the first electric push rod 404 to reciprocate the retraction and extension, the cardboard can be continuously pushed above the conveyor belt 2.

[0028] The feeding assembly 4 also includes an alignment structure for arranging the cardboard stacked above the carrier plate 402. The alignment structure includes a second electric push rod 406 installed inside the loading bin 401 near the side wall of the conveyor belt 2. The telescopic end of the second electric push rod 406 is fixedly connected to a forward push plate 407. By controlling the extension of the second electric push rod 406, the second electric push rod 406 will push the forward push plate 407 towards the front of the cardboard, thus arranging the cardboard placed on the carrier plate 402 in a positive orientation. The alignment structure also includes a dual-head motor 408 installed at the bottom of the loading bin 401. The two output ends of the dual-head motor 408 are fixedly connected to a set of screws with opposite thread directions. 409, a set of lead screws 409 are threaded with movable plates 410 on their outer surfaces. The top of each movable plate 410 extends above two carrier plates 402 and is fixedly connected with a side push plate 411. The dual-head motor 408 is set to control the operation of the dual-head motor 408. The dual-head motor 408 will drive the side push plates 411 at both ends of the lead screw 409 to laterally sort the cardboard placed on the carrier plate 402, thus completing the sorting work and preventing the cardboard to be cut above the carrier plate 402 from being too messy. This ensures that the L-shaped push plate 405 can neatly push the cardboard to be cut above the carrier plate 402 onto the conveyor belt 2, thereby ensuring the normal operation of subsequent work.

[0029] A positioning structure for guiding the cardboard above the conveyor belt 2 includes a threaded rod 412 rotatably connected to the inner wall of the loading box 401. A set of guide plates 413 are threaded onto the outer surface of the threaded rod 412. Each guide plate 413 has an arc-shaped end near the carrier plate 402. The guide plates 413 guide the cardboard during movement, and the arc shape at one end ensures smooth entry of the cardboard between the guide plates 413. Rotating the threaded rod 412 allows the guide plates 413 to move, thereby adjusting the cardboard's position. The spacing between the guide plates 413 is adjusted to accommodate cardboard of different sizes. A positioning rod 414 is slidably connected to a group of guide plates 413. Both ends of the positioning rod 414 are connected to the inner wall of the loading box 401. The positioning rod 414 can stabilize the guide plates 413 and prevent them from rotating, ensuring that the guide plates 413 move smoothly on the positive and negative threaded rods 412. One end of the positive and negative threaded rods 412 extends to the outside of the loading box 401 and is fixedly connected to a rotating handle 415. The rotating handle 415 allows the operator to rotate the positive and negative threaded rods 412 more conveniently.

[0030] Working principle: When cardboard cutting is required, the operator first places the cardboard to be cut on the carrier plate 402 inside the loading box 401. The second electric push rod 406 is then extended, pushing the forward push plate 407 towards the cardboard's front, thus aligning the cardboard on the carrier plate 402. Next, the dual-head motor 408 is activated, driving the lateral push plates 411 at both ends of the lead screw 409 to laterally align the cardboard on the carrier plate 402. After aligning, the first electric push rod 404 is retracted, moving the L-shaped push plate 405. The L-shaped push plate 405 pushes the bottommost piece of cardboard on the carrier plate 402. The board moves the cardboard above the conveyor belt 2. Once a single cardboard piece is above the conveyor belt 2, the first electric push rod 404 is extended, causing the L-shaped push plate 405 to reset. The stacked cardboard pieces fall back above the carrier plate 402. Then, the first electric push rod 404 is reciprocated by contracting and extending, continuously pushing the cardboard pieces above the conveyor belt 2. When the cardboard pieces are transported to the designated position on the conveyor belt 2, the third electric push rod 302 is extended to push the cutter 303 downward to complete the cutting of the cardboard pieces. This avoids the inefficient and unstable operation mode of manual feeding, and can efficiently complete the cutting of packaging cardboard, ensuring the continuity of cardboard cutting work and further guaranteeing cutting efficiency.
