[0045] To make the technical problems, technical solutions, and beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0046] like Figures 1 to 4 As shown in the figure, this embodiment discloses a vacuum adsorption stacking and feeding mechanism for square paper, including a frame 1, on which a receiving platform 1-1 for receiving materials is provided.

[0047] A fixed blade roller 2 is fixedly mounted on the frame 1. Fixed blades 2-1 arranged axially are arranged on the circumferential wall of the fixed blade roller 2. A rotatable adsorption cutting roller 3 is mounted on the lower side of the fixed blade roller 2. Cutting blades 3-1 arranged axially are arranged on the circumferential wall of the adsorption cutting roller 3. The cutting blades 3-1 are in contact with the fixed blades 2-1. Several cutting adsorption holes 3-2 are provided on one side of the cutting blades 3-1. In this embodiment, the cutting adsorption holes 3-2 are arranged on the side of the cutting blades 3-1 closest to the traction roller 8. It should be noted that in some embodiments, cutting adsorption holes 3-2 can also be provided on both sides of the cutting blades 3-1; this is not a limitation. The cutting adsorption holes 3-2 are connected to an external vacuum negative pressure device through an air passage arranged inside the adsorption cutting roller 3, thereby generating an adsorption force to hold the raw paper. In this embodiment, the two ends of the adsorption cutting roller 3 are rotatably connected to the frame 1, wherein one end of the adsorption cutting roller 3 passes through the frame 1 and is connected to the motor drive, and the motor drives the adsorption cutting roller 3 to rotate.

[0048] On one side of the frame 1, a traction roller 8, an embossing roller 9, and a raw paper feeding roller 10 are arranged in sequence. Raw paper is wound on the raw paper feeding roller 10. The two embossing rollers 9 and the traction rollers 8 are arranged one above the other and are all driven by a motor. The raw paper drawn out by the raw paper feeding roller 10 is squeezed by the two embossing rollers 9, passes through the middle gap, and is embossed with patterns. Then, it enters between the two traction rollers 8, which pull it between the fixed blade roller 2 and the suction cutting roller 3. The fixed blade roller 2 is in a fixed state, while the suction cutting roller 3 rotates with the raw paper. When the cutting blade 3-1 contacts the fixed blade 2-1, the raw paper is cut. At the same time, the cutting suction hole 3-2 holds the raw paper and continues to rotate. When the second cutting blade 3-1 contacts the fixed blade 2-1, the raw paper is cut again, thus cutting the raw paper into square paper sheets.

[0049] like Figure 1 , Figure 2 and Figures 5 to 11 As shown, a first adsorption feed roller 4 and a second adsorption feed roller 5 are arranged horizontally side by side and are rotatable. A paper pressing fork 6 is arranged below the first adsorption feed roller 4 and the second adsorption feed roller 5.

[0050] The first adsorption feeding roller 4 includes a first inner fixed shaft 4-1, which is fixedly mounted on the frame 1. A rotatable first outer rotating cylinder 4-2 is sleeved on the first inner fixed shaft 4-1, and the inner circumferential wall of the first outer rotating cylinder 4-2 is in sealed sliding contact with the outer circumferential wall of the first inner fixed shaft 4-1.

[0051] The first outer rotating cylinder 4-2 has a first adsorption hole 4-2-1 and a second adsorption hole 4-2-2 on its circumferential wall. The first adsorption hole 4-2-1 and the second adsorption hole 4-2-2 are arranged alternately on the first outer rotating cylinder 4-2. The first outer rotating cylinder 4-2 has four rows of first V-shaped grooves 4-4 arranged on its circumferential wall. The first adsorption hole 4-2-1 or the second adsorption hole 4-2-2 are arranged on the inner walls of the left and right sides of the first V-shaped grooves 4-4.

[0052] The first inner fixed shaft 4-1 is provided with a first suction chamber 4-1-1 and a second suction chamber 4-1-2 connected to an external vacuum negative pressure device. The first suction chamber 4-1-1 and the second suction chamber 4-1-2 are isolated from each other. When the first outer rotating cylinder 4-2 rotates to a certain position, the first adsorption hole 4-2-1 will communicate with the first suction chamber 4-1-1. At this time, the first adsorption hole 4-2-1 will generate negative pressure suction. As rotation continues, when the first adsorption hole 4-2-1 leaves the first suction chamber 4-1-1, it will no longer generate negative pressure suction. Similarly, when the first outer rotating cylinder 4-2 rotates to a certain position, the second adsorption hole 4-2-2 will communicate with the second suction chamber 4-1-2. At this time, the second adsorption hole 4-2-2 will generate negative pressure suction. As rotation continues, when the second adsorption hole 4-2-2 leaves the second suction chamber 4-1-2, it will no longer generate negative pressure suction.

[0053] In this embodiment, the first V-groove 4-4 is provided in four rows, two of which are provided with first adsorption holes 4-2-1, and the other two rows are provided with second adsorption holes 4-2-2. The first V-groove 4-4 where the first adsorption holes 4-2-1 are located and the first V-groove 4-4 where the second adsorption holes 4-2-2 are located are alternately and evenly distributed in four positions on the circumferential wall of the first outer rotating cylinder 4-2.

[0054] In one embodiment of realizing the communication between the first adsorption hole 4-2-1 and the first suction chamber 4-1-1, in this embodiment, multiple first adsorption holes 4-2-1 are provided and arranged in a row. The first adsorption hole 4-2-1 is connected to one end of the first bronchus 4-2-3, and the other end of the first bronchus 4-2-3 converges to the first air inlet 4-2-4. The first air inlet 4-2-4 is connected and cooperates with the first suction chamber 4-1-1.

[0055] In one embodiment of realizing the communication between the second adsorption hole 4-2-2 and the second air intake chamber 4-1-2, in this embodiment, multiple second adsorption holes 4-2-2 are provided and arranged in a row. The second adsorption holes 4-2-2 are connected to one end of the second bronchus 4-2-5, and the other end of the second bronchus 4-2-5 converges to the second air inlet 4-2-6. The second air inlet 4-2-6 is connected and cooperates with the second air intake chamber 4-1-2.

[0056] The second adsorption feeding roller 5 includes a second inner fixed shaft 5-1, which is fixedly mounted on the frame 1. A rotatable second outer rotating cylinder 5-2 is sleeved on the second inner fixed shaft 5-1, and the inner circumferential wall of the second outer rotating cylinder 5-2 is in sealed sliding contact with the outer circumferential wall of the second inner fixed shaft 5-1.

[0057] The second outer rotating cylinder 5-2 has a third adsorption hole 5-2-1 on its circumferential wall that is connected to an external vacuum negative pressure device. The second outer rotating cylinder 5-2 has two rows of second V-shaped grooves 5-4 on its circumferential wall. The third adsorption hole 5-2-1 is arranged on the inner walls of the left and right sides of the two rows of second V-shaped grooves 5-4.

[0058] The second inner fixed shaft 5-1 is provided with a third suction chamber 5-1-1. The third adsorption hole 5-2-1 is connected to the third suction chamber 5-1-1. That is, when the second outer rotating cylinder 5-2 rotates to a certain position, the third adsorption hole 5-2-1 will be connected to the third suction chamber 5-1-1. At this time, the third adsorption hole 5-2-1 will generate negative pressure suction. As the rotation continues, when the third adsorption hole 5-2-1 leaves the third suction chamber 5-1-1, it will no longer generate negative pressure suction.

[0059] In one embodiment of realizing the connection between the third adsorption hole 5-2-1 and the third suction chamber 5-1-1, in this embodiment, multiple third adsorption holes 5-2-1 are provided and arranged in a row. The third adsorption holes 5-2-1 are connected to one end of the third bronchus 5-2-2, and the other end of the third bronchus 5-2-2 converges to the third air inlet 5-2-3. The third air inlet 5-2-3 is connected and cooperates with the third suction chamber 5-1-1.

[0060] When the cutting and adsorption hole 3-2, adsorbing the lower end of the paper sheet, rotates to be close to the first adsorption feeding roller 4, the cutting and adsorption hole 3-2 is aligned with the first adsorption hole 4-2-1. At this time, the vacuum negative pressure device is controlled to stop the adsorption of the cutting and adsorption hole 3-2, and the first adsorption hole 4-2-1 begins to adsorb, thereby transferring the paper sheet to the first adsorption feeding roller 4. The first adsorption feeding roller 4 carries the paper sheet and rotates downwards towards the side of the second adsorption feeding roller 5. At the same time, the second adsorption feeding roller 5 also rotates downwards synchronously with the first adsorption feeding roller 4. When the cutting and adsorption hole 3-2 rotates away from the second adsorption feeding roller 5 and is close to the direction of the original paper entry again, the negative pressure system is activated and the cutting and adsorption hole 3-2 begins to adsorb the newly entered original paper again.

[0061] like Figure 12 As shown, in this embodiment, one end of the first outer rotating cylinder 4-2 passes through the frame 1 and is fixedly equipped with a first gear 4-3, and one end of the second outer rotating cylinder 5-2 passes through the frame 1 and is fixedly equipped with a second gear 5-3. The first gear 4-3 and the second gear 5-3 are meshed and connected. One end of the first outer rotating cylinder 4-2 is connected to an external drive motor through a transmission belt and a transmission wheel. The motor drives the first outer rotating cylinder 4-2 to rotate, and at the same time, the first outer rotating cylinder 4-2 drives the second outer rotating cylinder 5-2 to rotate synchronously through the first gear 4-3 and the second gear 5-3.

[0062] like Figure 5 and Figures 13 to 14As shown, annular grooves 11 are provided on the circumferential walls of the first outer rotating cylinder 4-2 and the second outer rotating cylinder 5-2. One end of the paper pressing fork 6 can be moved up and down into the annular groove 11, and the other end of the paper pressing fork 6 is rotatably connected to the frame 1.

[0063] The paper pressing fork 6 includes a fixed roller shaft 6-1 and a fork rod 6-2. The two ends of the fixed roller shaft 6-1 are rotatably connected to the frame 1. The fixed roller shaft 6-1 is provided with a mounting groove 6-3, and one end of the fork rod 6-2 is embedded in the mounting groove 6-3.

[0064] A clamping cover plate 6-4 is provided between the two mounting slots 6-3. The two ends of the clamping cover plate 6-4 are tightly pressed against the shift fork rod 6-2, and the middle part of the clamping cover plate 6-4 is connected to the fixed roller shaft 6-1 by a bolt assembly. In this embodiment, the shift fork rod 6-2 is provided with a clamping groove 6-2-1. During installation, the two ends of the clamping cover plate 6-4 are tightly pressed against the clamping groove 6-2-1.

[0065] The frame 1 is provided with a stop groove plate 7 for limiting the position of the fork lever 6-2. The stop groove plate 7 is located below the paper pressing fork 6. The stop groove plate 7 is provided with a number of stop grooves 7-1. The stop grooves 7-1 and the fork lever 6-2 are movably embedded and engaged. That is, when the fork lever 6-2 rotates downward, it will enter the stop groove 7-1. When the fork lever 6-2 rotates in the opposite direction, it can exit from the stop groove 7-1.

[0066] The working principle of this invention is as follows:

[0067] like Figures 10 to 11 Combination Figures 15 to 19 As shown, in this embodiment, the first adsorption feeding roller 4 rotates counterclockwise in the directions a1, a2, a3, a4; the second adsorption feeding roller 5 rotates clockwise in the directions b1, b2, b3, b4. The range of the first suction chamber 4-1-1 is from a1 to a2, the range of the second suction chamber 4-1-2 is from a1 to a3, and the range of the third suction chamber 5-1-1 is from b2 to b3; that is, the first adsorption hole 4-2-1 generates negative pressure suction in the region from a1 to a2, the second adsorption hole 4-2-2 generates negative pressure suction in the region from a1 to a3, and the third adsorption hole 5-2-1 generates negative pressure suction in the region from b2 to b3. In this embodiment, the adsorption cutting roller 3 rotates clockwise.

[0068] The raw paper enters between the fixed blade roller 2 and the suction cutting roller 3 through two embossing rollers 9 and traction roller 8. The suction cutting roller 3 rotates with the raw paper. When the cutting blade 3-1 contacts the fixed blade 2-1, the raw paper is cut. At the same time, the cutting suction hole 3-2 holds the raw paper and continues to rotate. When the second cutting blade 3-1 contacts the fixed blade 2-1, the raw paper is cut again, thus cutting the raw paper into square pieces.

[0069] When the bottom of the first paper is rotated to a position close to a1, the adsorption hole 3-2 is cut and adsorbed. Figure 15 As shown), the adsorption hole 3-2 is cut to stop adsorption. The first adsorption hole 4-2-1 also rotates to position a1 and connects with the first suction chamber 4-1-1 to begin adsorption and hold the lower end of the first paper as it rotates towards position a2. At the same time, the third adsorption hole 5-2-1 also rotates from position b1 to position b2. When the first adsorption hole 4-2-1 meets the third adsorption hole 5-2-1 at position a2 (as shown), Figure 16 As shown), the first adsorption hole 4-2-1 stops adsorption, the third adsorption hole 5-2-1 connects with the third suction chamber 5-1-1 to start adsorption, and the lower end of the first sheet of paper is adsorbed onto the second adsorption feeding roller 5 and continues to rotate downward to position b3. When position b3 is reached, the third adsorption hole 5-2-1 stops adsorption, and the fixed roller shaft 6-1 below the second adsorption feeding roller 5 drives the shift fork rod 6-2 to rotate. The shift fork rod 6-2 located in the annular groove 11 rotates downward, thereby pressing the lower end of the first sheet of paper onto the receiving platform 1-1 (as shown). Figure 17 (As shown), after pressing, the shift fork lever 6-2 returns to its original position;

[0070] In the above process, when the first adsorption pore 4-2-1 meets the third adsorption pore 5-2-1 at position a2 (e.g.) Figure 16 As shown), the second adsorption hole 4-2-2 reaches position a1 and connects with the second suction chamber 4-1-2 to begin generating adsorption force. At this time, the second adsorption hole 4-2-2 encounters the cutting adsorption hole 3-2 at position a1, adsorbing the upper end of the first paper and the lower end of the second paper onto the second adsorption hole 4-2-2 and rotating, passing through position a2 (as shown). Figure 17 (as shown), then continue rotating to position a3 (as shown). Figure 18 As shown), at this time, the second adsorption hole 4-2-2 disengages from the second suction chamber 4-1-2, adsorption stops, and the fixed roller shaft 6-1 below the first adsorption feeding roller 4 drives the shift fork rod 6-2 to rotate. The shift fork rod 6-2 located in the annular groove 11 rotates downward, thereby pressing the upper end of the first sheet of paper and the lower end of the second sheet of paper onto the receiving table 1-1 (as shown). Figure 18 (As shown), after pressing, the shift fork lever 6-2 returns to its original position;

[0071] Similarly, when the second adsorption hole 4-2-2 adsorbs the upper end of the first paper and the lower end of the second paper to position a2, another adjacent first adsorption hole 4-2-1 rotates to position a1 and begins to adsorb the upper end of the second paper and the lower end of the third paper (as shown). Figure 17 As shown), when the second adsorption hole 4-2-2 rotates to a3, the first adsorption hole 4-2-1 rotates to position a2 and meets another third adsorption hole 5-2-1. At this time, the first adsorption hole 4-2-1 stops adsorbing, and the third adsorption hole 5-2-1 begins to adsorb the upper end of the second paper and the lower end of the third paper, rotating towards b3 (as shown). Figure 18 As shown), when the third adsorption hole 5-2-1 rotates to b3, adsorption stops. The fixed roller shaft 6-1 below the second adsorption feed roller 5 drives the shift fork rod 6-2 to rotate. The shift fork rod 6-2, located in the annular groove 11, rotates downward, thereby pressing the upper end of the second sheet of paper and the lower end of the third sheet of paper onto the receiving table 1-1 (as shown). Figure 19 As shown), after pressing, the shift fork lever 6-2 resets; this process is repeated in sequence, thus realizing the flat stacking of square paper sheets onto the receiving table 1-1.
