Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1, an embodiment provided by the present utility model: a multi-color printing and die-cutting machine, including a die-cutting machine body 7 for processing corrugated cardboard boxes. A conveyor 1 is arranged at the front of the die-cutting machine body 7. It is provided with a belt for conveying corrugated paper. Vertical plates 11 are arranged on both the left and right sides of the conveyor 1 for cooperating and connecting various components. A feeding mechanism is arranged at the front of the conveyor 1 for automatic feeding. It can cooperate with the conveyor 1 to spread out the corrugated paper in the storage frame 2, facilitating the later material distribution by the limiting component 6, so that the corrugated cardboard can enter the die-cutting machine body 7 one by one. The feeding mechanism includes a storage frame 2, a baffle 3, and slide rails 4. The number of slide rails 4 is two. The slide rails 4 are fixedly connected to the vertical plates 11 and are used to adjust the height of the baffle 3. The left and right sides of the baffle 3 are respectively slidably connected to the two slide rails 4. The baffle 3 can limit the corrugated paper in the storage frame 2 to prevent the internal corrugated paper from toppling during the conveyance of the conveyor 1. Guide plates 5 are arranged on both the left and right sides of the middle part of the top surface of the conveyor 1. They are inclined and are used to straighten the corrugated cardboard. Fixed blocks 51 are fixedly connected to one side of the guide plates 5 close to the vertical plates 11 and the number is two for cooperating with the fixation of the guide plates 5. The two fixed blocks 51 are fixedly connected to the vertical plates 11. A limiting component 6 is arranged at the rear part of the top surface of the conveyor 1 for limiting the corrugated paper from entering the die-cutting machine body 7. It can only allow one corrugated paper to pass through at a time.

[0032] Please refer to Figure 2 - Figure 3 , the limiting component 6 includes an arc-shaped guide plate 64, the lower part of which is arc-shaped and has a guiding effect on the corrugated paper. The limiting component 6 also includes two slide bars 61, which are electric and are used to adjust the position of the slider 62. The slider 62 is slidably connected inside the slide bar 61 and is used to connect the support plate 63. The bottom of the slider 62 is fixedly connected to the support plate 63 for cooperating and connecting various components. An auxiliary roller 65 is rotatably connected between the two support plates 63. It can be driven to rotate when the corrugated paper passes through, assisting the movement of the corrugated paper. Connecting rods 641 are fixedly connected to both the left and right parts at the rear side of the arc-shaped guide plate 64 for cooperating with the connection of the arc-shaped guide plate 64. The connecting rods 641 are fixedly connected to the support plate 63. An arc-shaped slope 642 is arranged at the lower part of the arc-shaped guide plate 64 for cooperating with the use of the auxiliary roller 65.

[0033] As Figure 4 shown, the storage frame 2 includes vertical plates 21. Side plates 22 are fixedly connected to both the left and right sides of the vertical plates 21. The vertical plates 21 and the side plates 22 cooperate with each other to limit the corrugated paper by poking. The side plates 22 are fixedly connected to the vertical plates 11. A guide plate 23 is fixedly connected to the bottom of the vertical plates 21. It is inclined. When the conveyor 1 is started, it can assist the multiple corrugated papers in the storage frame 2 to tilt forward. A laying strip 24 is fixedly connected to the front side of the lower part of the guide plate 23 for laying the corrugated paper.

[0034] Working principle: When in use, first drive the baffle 3 to move downward through two slide rails 4, then stack the corrugated paper in the storage frame 2. After the corrugated paper is stacked, drive the baffle 3 to move upward through the slide rails 4 so that the baffle 3 blocks the corrugated paper. Then, according to the thickness of the corrugated paper, open the slide rod 61, which will drive the slider 62 to move. The slider 62 will drive the arc-shaped guide plate 64 and the auxiliary roller 65 through the support plate 63 connected to it, so that the gap between the arc-shaped guide plate 64 and the auxiliary roller 65 and the conveyor 1 belt only allows one corrugated paper to pass through. Then start the conveyor 1. When the belt of the conveyor 1 moves forward, the corrugated cardboard pressed on the belt of the conveyor 1 will be driven accordingly. Under the action of the guide plate 23 of the storage frame 2, the multi-layer corrugated cardboard will be staggered and tilted forward. When the corrugated cardboard passes through the laying strip 24, the laying strip 24 will assist in spreading out the corrugated cardboard. As the conveyor 1 belt moves forward, the corrugated cardboard will be brought between the two guide plates 5. The guide plates 5 will guide the corrugated paper to make it straight. The straightened corrugated paper will move to the lower part of the auxiliary roller 65 through the guidance of the arc-shaped guide plate 64. The auxiliary roller 65 will assist the corrugated cardboard to move into the die-cutting machine body 7. When the corrugated paper is conveyed into the die-cutting machine body 7, it will perform printing and cutting processing on the corrugated cardboard.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
