[0002] To improve slitting efficiency, existing cross-cutting machines typically have multiple rolls placed in their unloading devices. Simultaneously unloading multiple rolls can significantly improve paper slitting efficiency. However, existing unloading devices often place rolls side by side, which takes up a significant amount of factory floor space. Furthermore, due to height restrictions and the inability to adjust the unloading device's position, placing rolls is inconvenient. Summary of the Invention

[0016] As Figure 1 shown, this cross-cutting machine sequentially includes a feeding device 1, a deviation rectifying device (not shown), a material storage device 2, a longitudinal cutting device 3, a cross-cutting device 4, a conveying device 5 and a material arranging device 6 along the material feeding direction. The feeding device 1 is used for placing a material roll (such as paper or film); the deviation rectifying device rectifies the material discharged from the material roll (which is the prior art); the material storage device 2 caches the material; the longitudinal cutting device 3 divides the material into two parts along the left and right directions; the cross-cutting device 4 cuts off the material; the conveying device 5 conveys the cut material forward and sends it to the material arranging device 6; the material arranging device 6 stacks the material to form a stack and conveys it out.

[0017] As Figure 1 shown in Figure 2 and Figure 2 shown in Figure 2 , the feeding device 1 includes a central beam 10 and an unwinding unit. The central beam 10 has a plurality of mounting surfaces 14 around the axial direction (for example, the central beam 10 in

[0018] has four mounting surfaces, and of course, a certain number of mounting surfaces 14 can also be set according to needs). Each mounting surface 14 is provided with an unwinding unit. As Figure 2 shown, the unwinding unit includes two left and right roll supporting mechanisms. Each roll supporting mechanism includes a mounting seat 16 and a winding shaft 17. The winding shaft 17 is mounted on the mounting seat 16. One unwinding unit places one material roll. After the material roll is placed, the winding shafts 17 of the two left and right roll supporting mechanisms support the material roll; in addition, the central beam 10 is rotatably mounted on the support seat 11 through a rotating shaft, and the rotating shaft is in transmission connection with a power source 12 (motor) through a gear set 13.The working principle of the feeding device 1 is as follows: When working normally, each unwinding unit places a material roll. Since multiple unwinding units are arranged in upper and lower layers, the floor space can be greatly saved. When the material roll is used up, as long as the central beam 10 is driven to rotate by the power source 12, the unwinding unit with the used-up material roll is lowered to the lowest position, and then the roll is changed. Since the unwinding unit is in the low position, it is very convenient for workers to place a new material roll on this unwinding unit.

[0019] In order to adjust the position of the material roll and adapt to material rolls of different widths, in the present invention, a guide rail 15 is connected to the mounting surface 14 of the central beam 10. The mounting seat 16 is slidably arranged on the guide rail 15 through a slider, and the slider is in transmission connection with the piston rod of the oil cylinder. When it is necessary to adjust the position of the material roll, as long as the oil cylinder is used to drive the slider to move on the guide rail 15, the unwinding unit will axially move, thereby driving the material roll to move. When it is necessary to adapt to material rolls of different widths, it is also possible to move one of the roll supporting mechanisms in the unwinding unit, which is very convenient.

[0020] As described above, the conveying device 5 conveys the cut materials forward. However, existing conveying devices 5 all adopt an upper and lower roller shaft structure. However, there is a speed difference between the upper and lower roller shafts of the upper and lower roller shaft structure, which easily causes problems in feeding, generates friction on the materials, and affects the quality of the materials. For this reason, the conveying device 5 of the present invention adopts two upper and lower belt transmission mechanisms. The belt transmission mechanism includes a belt 50 and belt pulleys 51, and the belt 50 is wound around the belt pulleys 51. Since the speeds of the upper and lower belts can be accurately synchronized and there is generally no speed difference, the feeding is more stable and does not affect the quality of the materials.

[0021] As Figures 3 - 5 shown, the material sorting device 6 includes a blanking mechanism, a material supporting mechanism, and a feeding mechanism. The feeding mechanism includes a conveyor belt 66 with intervals (there are multiple conveyor belts 66); the blanking mechanism includes a blanking plate 62, a blanking rod 61, and a blanking power source 60 for driving the blanking rod 61 to move up and down. The blanking plate 62 is connected to the blanking rod 61, and the blanking plate 62 is located between two adjacent conveyor belts 66; the material supporting mechanism includes a material supporting plate 63 and a material supporting power source for driving the material supporting plate 63 to move back and forth; a baffle plate 64 is arranged in front of the conveying device, the baffle plate 64 is located above the material supporting plate 63, and the baffle plate 64 has a material supporting portion 640 facing the conveying device.

[0022] The working principle of the material sorting device 6 is as follows: As Figure 5 shown, the conveying device 5 conveys the cut materials forward and is blocked by the baffle plate 64. Since the material supporting plate 63 is located below the baffle plate 64, the materials fall onto the material supporting plate 63. As the materials are gradually stacked, when the stacking reaches the set height, the material supporting power source drives the material supporting plate 63 to move forward (as Figure 5In the left direction), so that the material is no longer supported by the material supporting plate 63 and falls onto the lower blanking plate 62. The blanking plate 62 is driven by the blanking power source 60 to move downward and pass through the interval of the conveyor belt 66, so that the material is placed on the conveyor belt 66. Finally, the conveyor belt 66 conveys the material to the next packaging station. And when the material falls onto the blanking plate 62, the material supporting power source drives the material supporting plate 63 to move backward (such as Figure 5 In the right direction), the material supporting plate 63 receives the material again, and the material supporting part 640 of the material blocking plate 64 can lift the front end of the material to ensure that the material supporting plate 63 can be inserted under the material. After the material supporting plate 63 receives the material again, it continues the stacking described above. In this way, the material can be continuously sorted, greatly improving the production efficiency.

[0023] Finally, it is worth mentioning that there are multiple partition plates 65 arranged left and right in front of the conveying device, such as Figure 3 And Figure 4 As shown, the partition plates 65 can separate the materials arranged side by side left and right to ensure that the left and right materials are not involved with each other. The bottom of the partition plate 65 has a notch 650 for the blanking plate 62 to enter, so that the lower part of the partition plate 66 can separate the bottommost material, and the blanking plate 62 can enter the notch 650 where the blanking plate 62 enters without interfering with the blanking plate 62.
