[0033] Example 1:

[0034] This embodiment Figure 1 、 Figure 2 and Figure 3 As shown, a paper collection machine includes: a frame 1, the frame 1 has a paper feeding channel; a paper feeding mechanism 2, the paper feeding mechanism 2 is installed on the frame 1 and is located in the paper feeding channel, and a paper positioning mechanism 14 is provided at the discharge end of the paper feeding channel; a paper collection mechanism 3, the paper collection mechanism 3 is installed on the frame 1 and is located at the discharge end of the paper feeding channel; wherein, the paper collection mechanism 3 includes a paper support 4, a screw 5 and a finisher 6, the screws 5 are symmetrically arranged and rotatably installed on both sides of the frame 1, the screws 5 are driven by a power source, the two sides of the paper support 4 are respectively threadedly connected to the two screws 5, the finisher 6 is installed in the frame 1 and is lower than the discharge end of the paper feeding channel, and the working end of the finisher 6 is arranged opposite to the working end of the paper positioning mechanism 14.

[0035] After printing or cutting, a single sheet of paper enters the paper inlet of the paper feeding channel of the frame 1. Under the action of the paper feeding mechanism 2 (which can be the structure in the automatic paper coding mechanism for digital high-speed slitting machine with publication number CN215439005U), the paper is conveyed to the paper support 4 of the paper collection mechanism 3. As the paper gradually accumulates, a thicker and thicker paper stack is formed. At this time, it is necessary to start the power source (such as a motor) to rotate the two lead screws 5 to drive the paper support 4 to gradually descend, so that the paper accumulates on one side and the paper support 4 descends on the other side to compensate for the height of the paper collection. While the paper is docking, the finisher 6 will always tidy up the upper paper of the paper stack to ensure the neatness of the entire paper stack.

[0036] A paper height sensor may also be provided on the frame 1 opposite to the paper support 4 to sense the height of the paper on the paper support 4 in real time and to control the lifting and lowering of the paper support 4 .

[0037] It is worth noting that the paper of a certain thickness on the top of the paper stack is located between the two sorters 6. The sorter 6 can be an existing alignment structure, such as a symmetrical paper sorting mechanism composed of a cylinder and a push plate.

[0038] Example 2:

[0039] Based on the above embodiments, this embodiment Figure 4 As shown, the finisher 6 includes a fixed plate 7, a vibration plate 8 and a vibrator 9. The fixed plate 7 is slidably mounted on the frame 1 and locked by bolts. The vibration plate 8 is slidably connected to the fixed plate 7. The vibrator 9 is mounted on the fixed plate 7, and the working end of the vibrator 9 is connected to the vibration plate 8.

[0040] Under the action of the vibrator 9, the vibration plate 8 hits the paper of a certain thickness on the top of the paper stack at a certain frequency (mainly hitting the right side of the upper part of the paper stack). At the same time, with the cooperation of the working end of the paper positioning mechanism 14 and the two inner sides of the frame 1, a sorting space for sorting the paper stack is formed. While sorting the paper stack, the paper support platform 4 is lowered to ensure the neatness of the entire paper stack. The frequency is adjustable, and the paper sorting effect is obvious, which greatly improves the efficiency and effect of paper stacking. During this period, in order to prevent the vibration plate 8 from moving and deviating, the fixed plate 7 and the vibration plate 8 are slidably connected. Other positional relationships such as the gap between the vibration plate 8 and the paper can be achieved by adjusting the position of the fixed plate 7.

[0041] It is worth noting that the paper of a certain thickness on the top of the paper stack is located between the two finishers 6 , and the distance between the two sides of the paper and the finishers 6 is very small.

[0042] Example 3:

[0043] Based on the above embodiments, this embodiment Figure 3As shown, the paper feeding mechanism 2 includes a transverse plate 10 and a conveyor belt 11. Multiple transverse plates 10 and multiple conveyor belts 11 are alternately installed in the paper feeding channel, and the upper belt surface of the conveyor belt 11 protrudes from the upper surface of the transverse plate 10.

[0044] The plurality of transverse plates 10 and the plurality of conveyor belts 11 are alternately arranged, firstly to ensure that the paper moves forward stably to the paper receiving station; secondly, to prevent the paper from being deflected during its movement.

[0045] Preferably, a paper guide 12 is installed on the frame 1 and is located above the paper feeding mechanism 2 .

[0046] The paper guide 12 can prevent the paper from warping on the conveyor belt 11, thereby ensuring stable conveyance of the paper.

[0047] Preferably, a paper pressing roller 13 is provided at the feeding end of the paper feeding mechanism 2 .

[0048] The paper pressing roller 13 cooperates with the conveying belt 11 to ensure that the paper can enter the paper feeding mechanism 2 smoothly.

[0049] Example 4:

[0050] Based on the above embodiment, this embodiment shows that the paper positioning mechanism 14 includes a belt roller 15, a belt pressure roller 16, a paper feed belt 17 and a paper stop 18. Multiple belt rollers 15 and at least one belt pressure roller 16 are rotatably installed in the paper feeding channel. The paper feed belt 17 is tensioned on the belt roller 15 and the belt pressure roller 16. The belt pressure roller 16 presses down the lower belt part of the paper feed belt 17. The paper stop 18 is installed at the tail of the paper feeding channel and is located below the paper feed belt 17.

[0051] The pressure roller 16 can press the paper feed belt 17 against the paper to ensure that the paper can be smoothly transported into the paper collection mechanism 3. It can also prevent the paper feed belt 17 from completely sticking to the paper, preventing the paper from being deformed and wrinkled due to the thrust and small deformable space.

[0052] Preferably, the belt roller 15 is provided with a plurality of belt grooves.

[0053] The belt groove prevents the paper feeding belt 17 from running off track.

[0054] Preferably, a cross bar 19 is slidably mounted on the frame 1 and locked by bolts, and a photoelectric sensor 21 electrically connected to a controller 20 on the paper delivery machine is mounted on the cross bar 19 .

[0055] The photoelectric sensor 21 can sense the paper situation (such as the paper position) and, under the control of the controller 20 , enables the paper feeding mechanism 2 and the paper receiving mechanism 3 and other mechanisms to work in coordination.

[0056] Preferably, the paper support 4 is equipped with a paper discharge belt 22 .

[0057] The paper discharge belt 22 facilitates the removal of the paper stack from the paper supporting platform 4 .

[0058] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
