For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0033] The following will refer to the attached Figures 1 to 7 The present invention will be described in detail with reference to the embodiments. Figure 1 As shown, the direction indicated by x is the front side of the present invention.

[0034] In general, the utility model relates to a carton printer, which includes a base plate 1, a first mounting frame 3 fixedly mounted on the top surface of the base plate 1, an electric push rod 301 fixedly mounted on the top of the first mounting frame 3, a sliding frame 302 fixedly mounted at the end of the electric push rod 301, a printing machine 305 slidingly mounted on the sliding frame 302, clamping components symmetrically fixedly mounted on both sides of the printing machine 305, and guide components symmetrically arranged on the front and rear sides of the first mounting frame 3 and located on the base plate 1, a screw 303 is provided in the sliding frame 302, both ends of the screw 303 are respectively rotatably connected to the two opposite sides of the sliding frame 302, and one end extends to the outside of the sliding frame 302 and is fixedly connected to the output shaft of the first motor 304, and the printing machine 305 is threadedly connected to the screw 303.

[0035] In this embodiment, printing on cardboard is performed on base plate 1. The power assembly transports the cardboard placed on base plate 1 to the bottom of first mounting frame 3. The electric push rod 301 drives the sliding frame 302 downward, thereby driving the printing press 305 toward the cardboard for printing. As the electric push rod 301 drives the printing press 305 downward, the clamping assembly compresses the cardboard below, securing it to base plate 1 to prevent accidental movement and misalignment. Furthermore, a first motor 304 is fixedly mounted on the sliding frame 302. Its rotation drives the screw 303, which drives the printing press 305 left and right, adapting to the printing needs of cardboards of varying widths. It should be understood that the printing press 305 is a digital printing press 305 mechanism.

[0036] The clamping assembly includes a horizontal plate 306 fixedly mounted on the side wall of the printing machine 305 , a lower pressure column 307 symmetrically arranged on the horizontal plate 306 , an inner groove 309 opened at the bottom end of the lower pressure column 307 , and a rotating wheel 310 rotatably arranged in the inner groove 309 .

[0037] During implementation, the electric push rod 301 drives the printing press 305 downward, causing the rotating wheel 310 to contact the cardboard placed on the bottom plate 1, pressing the cardboard tightly. Furthermore, the inner groove 309 is oriented in the same direction as the sliding direction of the printing press 305 on the sliding frame 302, allowing the rotating wheel 310 to rotate left and right. This allows the printing press 305 to slide left and right when pressing, preventing the bottom end of the pressing post 307 from damaging the cardboard.

[0038] As a preference, in order to prevent the electric push rod 301 from pushing the clamping assembly downward to deform the cardboard, based on the setting of the clamping assembly, in this embodiment, as Figures 2 to 4As shown, the lower pressure column 307 slides up and down on the horizontal plate 306 and is equipped with a tension spring 308. One end of the tension spring 308 is fixed to the top of the lower pressure column 307, and the other end is fixed to the top surface of the horizontal plate 306. When the electric push rod 301 drives the compression assembly downward, the rotating wheel 310 abuts the cardboard. As the electric push rod 301 continues to operate, the lower pressure column 307 slides on the horizontal plate 306, and the tension spring 308 stretches. While providing a compression effect, it also prevents the force of the electric push rod 301 from directly acting on the cardboard, creating a buffer. In addition, during actual operation, the outer circumference of the rotating wheel 310 is evenly fixed with multiple protrusions 311 to increase friction between the rotating wheel 310 and the cardboard to prevent slipping.

[0039] The above-mentioned guide assembly is mainly used to transport the cardboard to the printing position, such as Figure 7 As shown, it includes a slot 6 opened on the base plate 1, and a rotating roller 601 rotatably set in the slot 6, the end of the rotating roller 601 extends to the outside of the base plate 1 and is fixed with a first pulley 602, and the rotating roller 601 on the other side extends to the outside of the base plate 1 and is fixed with a second pulley 604, the first pulley 602 and the second wheel are connected by a belt 603, and the second pulley 604 is fixedly connected to the output shaft of the second motor 605.

[0040] In specific implementation, the second motor 605 is fixedly installed on the base plate 1. The second motor 605 is started to rotate, driving the second pulley 604 to rotate, and the power is transmitted to the second pulley 604, thereby realizing the synchronous rotation of the rotating rollers 601 on both sides.

[0041] As a preferred method, in order to prevent the paperboard from being covered with dust when printing, thereby affecting the quality of the printed product of the printing press 305, in this embodiment, as shown in FIG. Figure 1 and Figure 5 As shown, the side wall of the first mounting frame 3 is also provided with a dust removal assembly, which includes an extension plate 4 symmetrically fixed on the front side of the first mounting frame 3, a fixed plate 401 fixed between the extension plates 4, a sliding tube 402 arranged on the fixed plate 401, and an air suction hood 406 connected to the end of the sliding tube 402 and located below the fixed plate 401. The sliding tube 402 is connected to the dust collector 404 through a connecting tube 403.

[0042] In a specific implementation, the suction hood 406 is installed above the cardboard, and the dust collector 404 absorbs dust through the connecting pipe 403 and the sliding pipe 402. It should be noted that the specific structure of the dust collector 404 can refer to the existing vacuum cleaner structure, and the working principle is mainly based on the high-speed rotation of the motor and the airflow and vacuum effect generated thereby.

[0043] To accommodate cardboards of varying thicknesses, in this embodiment, a sliding tube 402 is slidably connected to a fixed plate 401. A spring 405 is mounted on the sliding tube 402. One end of the spring 405 is fixedly connected to the bottom surface of the fixed plate 401, and the other end is fixedly connected to the top surface of the suction hood 406. The sliding tube 402 is a rigid tube, while the connecting tube 403 is a flexible tube.

[0044] During specific implementation, the suction hood 406 will abut against the top of the cardboard, the sliding tube 402 will slide on the fixed plate 401, and the spring 405 will be compressed, which can ensure that the suction hood 406 always abuts against the top of the cardboard while allowing the suction hood 406 to slide up and down to adapt to cardboards of different thicknesses.

[0045] In order to prevent the suction hood from abutting against the cardboard, causing damage to the cardboard or affecting the guide assembly from conveying the cardboard, in this embodiment, as shown in FIG. Figure 5 As shown, a plurality of brushes 407 are evenly arranged on the bottom of the suction hood 406 .

[0046] In this embodiment, if Figure 1 and Figure 6 As shown, a drying assembly is also provided on the base plate 1 behind the first mounting frame 3. This assembly dries the printed paperboard, ensuring that the printed coating is completely dry. The assembly includes a second mounting frame 5 fixedly mounted on the top surface of the base plate 1, a blower pipe 501 fixedly mounted on the second mounting frame 5, a fan 503 fixedly mounted within the blower pipe 501, and an air hood 502 connected to the end of the blower pipe 501.

[0047] During specific implementation, the air blown by the fan 503 is blown out through the air blowing cover 502, which can dry the cardboard below it and blow away the dust or powder on the surface of the cardboard, thereby ensuring the cleanliness of the cardboard.

[0048] As a preferred structure of this embodiment, in this embodiment, if Figure 1 As shown, in order to prevent the cardboard from being misaligned on the bottom plate 1, causing the cardboard to tilt into the printing position and affect the printing accuracy, in this embodiment, a limit plate 2 is symmetrically slidably provided on the top surface of the bottom plate 1. The limit plate 2 can clamp the cardboard in the middle, ensuring that the cardboard is parallel to the bottom plate 1, thereby improving the printing accuracy.

[0049] In addition, continue as Figure 1 As shown, in this embodiment, a plurality of supporting legs 101 are evenly arranged at the bottom of the bottom plate 1. An inclined plate 102 for the paperboard to slide down is fixedly arranged at the rear side of the bottom plate 1.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
