[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figs. 1 to 4 This utility model provides a technical solution: a pressure-free paper feeding device for cartons, including a transport box 1, a negative pressure chamber 3 is provided inside the transport box 1, a plurality of transport rollers 4 are rotatably fitted inside the negative pressure chamber 3, a driving structure is installed on one side of the transport box 1, the driving structure corresponds to the transport rollers 4, a plurality of sliding plates 10 are slidably fitted on the transport box 1, a plurality of first vent holes 8 are provided on the transport box 1, a plurality of second vent holes 9 are provided on the sliding plates 10, and two electric slide rails 14 are slidably fitted on the upper side of the transport box 1, the output end of the electric slide rails 14 is equipped with a push rod 16, the push rod 16 corresponds to the sliding plate 10.

[0021] In this embodiment, a vacuum pump 7 is fixed to the lower side of the transport box 1, and the air inlet of the vacuum pump 7 is connected to the negative pressure chamber 3.

[0022] Specifically, by starting the vacuum pump 7, air can be drawn out, creating a negative pressure environment in the negative pressure chamber 3. This environment generates an adsorption force through the first vent 8, thereby adsorbing the cardboard and preventing displacement during transportation.

[0023] The drive structure includes a motor 6, and belts 5 are installed between the output end of the motor 6 and one of the conveyor rollers 4, and between the two connected conveyor rollers 4.

[0024] Specifically, starting motor 6 causes it to drive conveyor roller 4 to rotate via belt 5, thus transporting the cardboard.

[0025] The first vent 8 corresponds to the second vent 9. The first vent 8 is connected to the negative pressure chamber 3. Two connecting plates 12 are fixed between the multiple slide plates 10. Baffles 2 are fixed on both sides of the transport box 1. Electric cylinders 11 are fixed on the baffles 2. A support plate 13 is fixed between the two baffles 2. The support plate 13 is fixedly connected to the electric slide rail 14. A slider 15 is fixed at the output end of the electric slide rail 14. The slider 15 is fixedly connected to the push rod 16. A friction block is fixed at the bottom of the push rod 16. The friction block is in contact with the slide plate 10.

[0026] Specifically, when the position of the cardboard needs to be adjusted, the electric slide rail 14 is activated, which drives the push rod 16 to move via the slider 15. The push rod 16 then pushes the cardboard to move, thereby adjusting its position. During adjustment, the push rod 16 drives the slide plate 10 to move via the friction block, causing the first vent 8 and the second vent 9 to misalign, which reduces the adsorption effect on the cardboard. This makes it easier to push the cardboard to move, thus preventing the cardboard from wrinkling.

[0027] Once the movement is complete, activate the electric cylinder 11 to push the slide plate 10 back to its original position, thus ensuring the effective adhesion of the cardboard.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
