[0022] In this embodiment, the distance between the two aligning plates 3 can be adjusted according to the length of the printed product by connecting the screws 12 to the corresponding positioning holes 10. When the second mounting rod 13 moves downward with the first conveyor belt 8, the printed product will be automatically centered due to the interference of the two aligning plates 3, and the position of the printed product is now arranged.

[0025] Among them, the outer wall of the second mounting rod 13 is fixedly connected to two upper airbags 17 and two lower airbags 23, the two upper airbags 17 are located above the conveying motor 19, and the two lower airbags 23 are located below the conveying motor 19, the outer wall of the second mounting rod 13 is fixedly connected to a baffle 4, and a surface jet assembly 21 and an edge jet assembly 22 are arranged below the baffle 4, the surface jet assembly 21 is located above the edge jet assembly 22, and the surface jet assembly 21 and the edge jet assembly 22 are both fixedly connected to the second mounting rod 13, the surface jet assembly 21 is connected to the two lower airbags 23 through a ventilation pipe, and the edge jet assembly 22 is connected to the two upper airbags 17 through a ventilation pipe, and the inner wall of the second mounting rod 13 is fixedly connected to two symmetrically distributed circular tooth block groups 16, and the two fifth gears 36 are respectively engaged with the two circular tooth block groups 16.

[0026] In this embodiment, if Figure 4 and Figure 8 As shown, when the receiving rod 5 and the second conveyor belt 15 receive the printed matter, the conveying motor 19 drives the transmission rod 34 to rotate in the direction of the second mounting rod 13, so that the printed matter can be tightly attached to the outer wall of the second mounting rod 13, and at the same time, the cam 33 continuously and repeatedly squeezes the lower air bag 23, so that the surface jet assembly 21 can blow air on the upper surface of the printed matter to prevent the cut scraps from falling within a certain range between the two second conveyor belts 15, and then the conveying motor 19 stops.

[0027] Among them, the inverted hanging mechanism 303 includes a first gear 26, a third gear 32, a second gear 27, a mounting column 29, a first rack 28, a pushing frame 31 and two first springs 30. The first gear 26 and the third gear 32 are meshed with each other. The first gear 26 and the third gear 32 are both rotatably connected to the second mounting rod 13. The second gear 27 is fixedly connected to the third gear 32. The second gear 27 is meshed with the first rack 28. The first rack 28 is fixedly connected to the third gear 32. The mounting column 29 is fixedly connected to the second mounting rod 13. The pushing frame 31 is slidably connected to the inner wall of the mounting column 29. The two first springs 30 are fixedly connected between the pushing frame 31 and the mounting column 29. Two inverted hanging mechanisms 303 are arranged on the second mounting rod 13, and the two inverted hanging mechanisms 303 are symmetrically distributed.

[0028] The outer walls of the two receiving rods 5 are fixedly connected with the limiting slide bars 14 , and the two limiting slide bars 14 are slidably connected with the two frames 1 respectively. The upper and lower surfaces of the two circular slide rail frames 44 are fixedly connected with the first gear block group 46 .

[0029] In this embodiment, since the scraps of printed materials will fall randomly, they may be above the printed materials, below the printed materials, or between the second conveyor belt 15 and the printed materials. Therefore, when the limiting slide bar 14 moves to the bottom along the frame 1, since the bottom of the frame 1 is an inclined surface, the limiting slide bar 14 will drive the two receiving rods 5 away from each other.

[0030] Then the first conveyor belt 8 drives the second mounting rod 13 and the second slide rod 24 to move to the bottom arc of the return slide rail frame 44. Due to the effect of gravity, the scraps will fall off by themselves. Figure 6 , Figure 7 , Fig.11 and Fig.13 As shown, the first gear 26 is meshed with the first gear block set 46, driving the third gear 32 to rotate, as shown in FIG. Figure 5 As shown, the third gear 32 drives the second gear 27 to rotate counterclockwise, so that the first rack 28 drives the push frame 31 to move upward, as shown in FIG. Figure 8 As shown, the third slide bar 37 and the upper abutment block 18 are located in the same plane. When the second mounting rod 13 is located on the other side of the first conveyor belt 8, the two receiving rods 5 still carry the printed matter. When the receiving rod 5 abuts against the upper abutment block 18, the clamping plate 40 releases the clamping of the printed matter. At this time, the conveying motor 19 rotates the cam 33 to squeeze the upper airbag 17, and the edge jet assembly 22 assists it to detach from the second conveyor belt 15, and the printed matter is conveyed in the direction away from the second mounting rod 13 to be stacked.

[0031] Among them, the clamping mechanism 404 includes an upper contact block 18, a lower contact block 20, a second connecting rod 38, a second spring 39, a clamping plate 40, a lower pressure plate 41, a displacement plate 42 and a fixed inclined plate 43. The upper contact block 18 and the lower contact block 20 are both slidably connected to the second mounting rod 13, the second connecting rod 38 is fixedly connected to the upper contact block 18 and the lower contact block 20, the second spring 39 is fixedly connected between the second connecting rod 38 and the second mounting rod 13, the displacement plate 42 is fixedly connected to the second connecting rod 38, the lower pressure plate 41 is slidably connected to the displacement plate 42, the fixed inclined plate 43 is fixedly connected to the second mounting rod 13, the clamping plate 40 is slidably connected to the lower pressure plate 41, and the clamping plate 40 is slidably connected to the fixed inclined plate 43.

[0032] In this embodiment, if Figure 8-Figure 10 As shown, the receiving rod 5 no longer contacts the lower contact block 20, and the lower contact block 20 moves due to the elastic force of the second spring 39, and the lower contact block 20 drives the upper contact block 18, the second spring 39 and the displacement plate 42 to move together, so that the displacement plate 42 presses the lower pressure plate 41 downward, and when the lower pressure plate 41 moves downward, the internal clamping plate 40 moves along the fixed inclined plate 43 and extends out, so that the clamping plate 40 and the second mounting rod 13 clamp the printed matter together to avoid the change of the position of the printed matter.

[0033] A plurality of second mounting rods 13 are disposed on the outer wall of the first conveyor belt 8 , and each second mounting rod 13 is fixedly connected to the first conveyor belt 8 .

[0034] The specific working principle and use method of the present invention are explained in detail below: When in use, it is assumed that the printed matter carried has a certain hardness, and the first motor 6 is as follows: Figure 2 The first motor 6 rotates clockwise in the direction shown, so that the first conveyor belt 8 is driven to move through the two transmission shafts 7, and the first conveyor belt 8 drives a plurality of second mounting rods 13 to move. The rotation speed of the first motor 6 is set to match the speed of printed matter discharge. When the second mounting rods 13 move to the discharge height, each two receiving rods 5 only carry one printed matter, and then move downward, and the height of the printed matter discharge is set to be above the aligning plate 3.

[0035] like Figure 4 and Figure 8 As shown, when the receiving rod 5 and the second conveyor belt 15 receive the printed matter, the conveying motor 19 drives the transmission rod 34 to rotate in the direction of the second mounting rod 13, so that the printed matter can be tightly attached to the outer wall of the second mounting rod 13, and at the same time, the cam 33 continuously and repeatedly squeezes the lower air bag 23, so that the surface jet assembly 21 can blow air on the upper surface of the printed matter to prevent the cut scraps from falling within a certain range between the two second conveyor belts 15, and then the conveying motor 19 stops.

[0036] The distance between the two aligning plates 3 can be adjusted according to the length of the printed product by connecting the screws 12 to the corresponding positioning holes 10. When the second mounting rod 13 moves downward with the first conveyor belt 8, the printed product will be automatically centered due to the interference of the two aligning plates 3, and the position of the printed product is now arranged.

[0037] Since the scraps of printed products will fall randomly, they may be above the printed products, below the printed products, or between the second conveyor belt 15 and the printed products. Therefore, when the limiting slide bar 14 moves to the bottom along the frame 1, since the bottom of the frame 1 is an inclined surface, the limiting slide bar 14 will drive the two receiving rods 5 away from each other.

[0038] like Figure 8-Figure 10 As shown, the receiving rod 5 no longer contacts the lower contact block 20, and the lower contact block 20 moves due to the elastic force of the second spring 39, and the lower contact block 20 drives the upper contact block 18, the second spring 39 and the displacement plate 42 to move together, so that the displacement plate 42 presses the lower pressure plate 41 downward, and when the lower pressure plate 41 moves downward, the internal clamping plate 40 moves along the fixed inclined plate 43 and extends out, so that the clamping plate 40 and the second mounting rod 13 clamp the printed matter together to avoid the change of the position of the printed matter.

[0039] Then the first conveyor belt 8 drives the second mounting rod 13 and the second slide rod 24 to move to the bottom arc of the return slide rail frame 44. Due to the effect of gravity, the scraps will fall off by themselves. Figure 6 , Figure 7 , Fig.11 and Fig.13 As shown, the first gear 26 is meshed with the first gear block set 46, driving the third gear 32 to rotate, as shown in FIG. Figure 5 As shown, the third gear 32 drives the second gear 27 to rotate counterclockwise, so that the first rack 28 drives the push frame 31 to move upward, as shown in FIG. Figure 8 As shown, the third slide bar 37 and the upper abutment block 18 are located in the same plane. When the second mounting rod 13 is located on the other side of the first conveyor belt 8, the two receiving rods 5 still carry the printed matter. When the receiving rod 5 abuts against the upper abutment block 18, the clamping plate 40 releases the clamping of the printed matter. At this time, the conveying motor 19 rotates the cam 33 to squeeze the upper airbag 17, and the edge jet assembly 22 assists it to detach from the second conveyor belt 15, and the printed matter is conveyed in the direction away from the second mounting rod 13 to be stacked.

[0040] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
