[0019] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0020] 1. A printing material trimming and processing device, wherein a first electric push rod drives a placement frame to tilt, so that the bottom of a paper pile contacts a movable plate under the action of gravity, and a driving motor drives a cam to rotate, and cooperates with a first spring to move the movable plate up and down, driving the paper pile to shake up and down. During the shaking process, the paper is affected by the downward trend of gravity, and its bottom side can be gradually aligned, thereby improving the neatness of the bottom of the paper and laying a foundation for subsequent trimming. The setting of a fixed block, an insertion rod and a second spring, when the movable plate collides with the insertion rod when the first spring force is reset, the movable plate is shaken again with the help of the second spring force, thereby increasing the shaking frequency, further optimizing the paper alignment effect, making the position of the paper more stable during trimming, and reducing the trimming error caused by misaligned paper.

[0021] 2. This printing material trimming and processing device is provided with a telescopic rod, a third spring, a push plate, a connecting plate and a sorting plate on a fixed block. When the cam rotates, the push plate moves left and right and drives the sorting plate to move left and right through the connecting plate, thereby shaking the left and right sides of the paper to achieve alignment of the two sides of the paper, ensuring the overall neatness of the paper from multiple directions, which is conducive to improving the trimming accuracy.

[0022] 3. This printing material trimming and processing device generates negative pressure on the right side of the inner wall of the placement frame through the coordinated work of an air pump, a connecting pipe, a frame and a screen plate, and adsorbs the right side of the paper through the mesh holes on the screen plate to achieve alignment of the right side of the paper. At the same time, the adsorption force helps to fix the position of the right side of the paper during the sorting and trimming process, and cooperates with the sorting plate to make the two sides of the paper more tidy, effectively preventing the paper from shifting during the processing process, and improving the stability of the paper during trimming.

[0023] 4. This printing material trimming and processing device, through the clamping structure composed of the second rotating rod, the threaded rod, the threaded sleeve and the clamping plate, cooperates with the placement frame to clamp and fix the two sides of the paper. When the driving motor drives the relevant components to move, the clamping plate can stably clamp the left side of the paper pile at the appropriate position, further enhancing the fixing effect of the paper in the horizontal direction, ensuring that the paper will not shake left and right during the trimming process, ensuring the accuracy of trimming, the second electric push rod drives the pressure plate to descend, and presses the top of the paper pile. This operation effectively prevents the paper from tilting due to external force during trimming, fixes the paper in the vertical direction, ensures the stability of the paper in the entire trimming process, and improves the trimming quality.

[0024] 5. This printing material trimming and processing device can drive the laser cutting machine to move through the third electric push rod, and can be flexibly adjusted according to the specific position requirements of paper trimming, ensuring that the laser cutting machine is always above the optimal cutting position, improving the accuracy of the trimming position, and meeting the processing of papers of different sizes and trimming requirements. The trimming plates in the slide grooves on both sides of the inner wall of the trimming frame, when the laser cutting machine descends, the pressure blocks fixed on the sides will squeeze the trimming plates downward, and the trimming positions of the paper will be further fixed by the trimming frame and the trimming plates to prevent the paper from shifting during the laser cutting process, ensuring the neatness and smoothness of the cutting lines, and improving the trimming effect.

At the same time, when the first rotating rod 62 rotates, it will drive the second rotating rod 616 to rotate through the synchronous belt pulley. The rotation of the second rotating rod 616 will drive the threaded rod 617 to rotate through the bevel gear set, thereby driving the threaded sleeve 618 to move to the right side, and the threaded sleeve 618 drives the clamping plate 619 to move to the right side. When the clamping plate 619 contacts the left side of the paper pile, the driving motor 61 is stopped, thereby fixing the paper pile. At the same time, the second electric push rod 76 is started to drive the pressing plate 77 to descend, and the top of the paper pile is pressed tightly.

[0040] See also Figure 1-8On the basis of the above embodiment, in another embodiment of the present invention, preferably, a trimming mechanism 8 is provided on the placement frame 5, and the trimming mechanism 8 includes a third electric push rod 81, a trimming frame 82, a mounting frame 86, a guide rail 87, a linear motor 88, a fourth electric push rod 89, and a laser cutting machine 810.

[0041] Working principle: After the paper pile is fixed, the other end of the paper pile passes through the trimming frame 82, and the third electric push rod 81 is started according to the position where the paper needs to be trimmed. The third electric push rod 81 drives the trimming frame 82 to move, so that the laser cutting machine 810 moves to the top of the cutting position, and the laser cutting machine 810 is driven to descend by starting the fourth electric push rod 89. At this time, the pressure block 811 will descend accordingly.
