[0013] Furthermore, the tray further comprises a baffle. When the paper is located directly above the tray, the unloading plate and the baffle can respectively abut against two opposite thickness sides of the paper.

[0014] In the above technical solution, by setting a baffle, when the paper is located directly above the tray, the unloading paper board and the baffle can respectively abut against the two opposite thickness sides of the paper. The baffle and the unloading paper board can jointly limit the paper, thereby making the paper fall on the tray more neatly.

[0015] Furthermore, it also includes a frame, the frame is provided with a plurality of adjustment holes, the plurality of adjustment holes are arranged horizontally, and the baffle is connected to the adjustment holes by bolts.

[0016] In the above technical solution, the baffle can be installed at one of the adjustment holes so that the horizontal distance from the baffle to the paper unloading plate can be adjusted, thereby making the distance between the baffle and the paper unloading plate adaptable to paper of different specifications and sizes.

[0017] Furthermore, the tray includes a plate body for supporting paper and a mounting plate detachably mounted on the plate body, the tray lead screw is threadedly connected to the mounting plate, and the plate body is fixed to the mounting plate by screws.

[0018] In the above technical solution, the screws are removed from the plate body, and the plate body and the mounting plate can be separated. The worker can then take away the plate body on which several stacks of paper are stacked, which is more convenient.

[0019] Furthermore, a plurality of rollers are detachably mounted on the bottom of the tray.

[0020] In the above technical solution, the rollers make it easier for workers to move the pallet.

[0021] To sum up, the present application has the following technical effects: a stack of paper is placed on a synchronous belt, the synchronous belt can transport the paper so that the thickness side wall of the paper can abut against the unloading paper board, and then the paper unloading assembly can make the paper leave the paper unloading platform and fall onto the tray.

[0026] Please refer to the attached drawings in the manual Figure 1 and 2 One embodiment of the present application provides an automatic unloading device for a paper cutter, comprising a frame 13 on which a paper unloading platform 1 is slidably mounted. The upper surface of the paper unloading platform 1 is flush with the upper surface of the paper cutting platform 21 of the paper cutter 2. Two pulleys 3 are rotatably mounted on the paper unloading platform 1, with the rotation axis of the pulleys 3 parallel to the ground. The two pulleys 3 are engaged with a common synchronous belt 4, with the end of the synchronous belt 4 facing away from the ground flush with the upper surface of the paper unloading platform 1. The synchronous belt 4 is used to place paper. The pulleys 3 are driven clockwise by a paper feed motor 5 to rotate the synchronous belt 4 so that the synchronous belt 4 can convey the paper. Above the paper unloading platform 1 is a vertically arranged unloading plate 6 that contacts the upper surface of the paper unloading platform 1. The synchronous belt 4 can convey the paper so that the thick side wall of the paper contacts the left side wall of the unloading plate 6. The paper can leave the synchronous belt 4 and the paper unloading platform 1 through a paper unloading assembly 7. A tray 8 is placed below the paper unloading platform 1 for receiving the paper unloaded by the paper unloading assembly 7.

[0027] Please refer to the attached drawings in the manual Figure 1The paper unloading assembly 7 includes a paper unloading driver 71 for driving the unloading plate 6 to move vertically and linearly to contact or move away from the synchronous belt 4, and a drive assembly 72 for driving the unloading platform 1 to move horizontally and linearly to deliver the paper to the position directly above the tray 8. For example, the paper unloading driver 71 can be an electric push rod or other drive capable of driving the unloading plate 6 to move vertically and linearly, so that the unloading plate 6 can be higher than the paper. The drive assembly 72 can use a screw threadedly connected to the unloading platform 1 and a motor that drives the screw to rotate. The motor drives the screw to rotate to drive the unloading platform 1 to move horizontally and linearly, so that the paper on the unloading platform 1 can be directly above the tray 8. When in use, first drive the paper unloading driver 71 to drive the paper unloading plate 6 to rise so that the paper unloading plate 6 is higher than the paper, and then drive the driving component 72 to drive the paper unloading platform 1 to move horizontally away from the paper cutting platform 21 until the paper is directly above the tray 8. At this time, the paper is on the right side of the paper unloading plate 6. Then drive the paper unloading driver 71 to drive the paper unloading plate 6 to move vertically downward so that the paper unloading plate 6 abuts against the synchronous belt 4. Then drive the driving component 72 to drive the paper unloading platform 1 to move horizontally in the opposite direction. At this time, the paper unloading plate 6 can block the paper so that the paper falls on the tray 8.

[0028] Please refer to the attached drawings in the manual Figure 1 The paper unloading platform 1 is equipped with a paperboard 9, the length direction of the paperboard 9 is perpendicular to the length direction of the unloading paperboard 6, and the paperboard 9 and the unloading paperboard 6 can respectively abut against the two adjacent thickness side walls of the paper.

[0029] Please refer to the attached drawings in the manual Figure 1 The tray 8 is threadedly connected to four tray screws 10. The tray screws 10 are vertically arranged and rotatably mounted on the frame 13. The tray screws 10 are driven and rotated by a tray motor 11, so that the tray 8 can be raised and lowered vertically and adjust its distance in the vertical direction relative to the paper unloading platform 1, so that the tray 8 can carry multiple stacks of paper. The tray 8 includes a plate 81 for carrying paper and a mounting plate 82 threadedly connected to the tray screws 10. The paper on the paper unloading platform 1 can be located directly above the plate 81. The plate 81 and the mounting plate 82 are connected by screws 16. The mounting plate 82 has two mounting plates and is located on the two width sides of the plate 81. Four rollers 15 are installed at the bottom of the plate 81. The rollers 15 make it easy for workers to remove the plate 81 carrying paper.

[0030] Please refer to the attached drawings in the manual Figure 1 Five adjustment holes 131 are arranged horizontally on the frame 13. A baffle 12 is installed on the side of the unloading plate 6 facing away from the paper cutting platform 21. The baffle 12 is located above the tray 8 and is mounted to the adjustment holes 131 via bolts 14. The multiple adjustment holes 131 allow for the space between the unloading plate 6 and the baffle 12 to accommodate paper of varying sizes. The baffle 12 and the unloading plate 6 can abut against opposing sides of the paper stack, ensuring that the paper is deposited neatly onto the tray 8.

[0031] The working principle of this embodiment is: first, place the paper on the synchronous belt 4 and the paper unloading platform 1, then turn on the paper feeding motor 5 to make the synchronous belt 4 transport the paper horizontally until the thickness side wall of the paper abuts the left wall of the unloading paper board 6, then the paper unloading driver 71 drives the unloading paper board 6 vertically away from the paper unloading platform 1 so that the unloading paper board 6 is higher than the paper, then the driving component 72 drives the paper unloading platform 1 to slide horizontally until the paper on the paper unloading platform 1 is directly above the plate body 81 and abuts the baffle 12. At this time, the paper is on the right side of the unloading paper board 6. At this time, the paper unloading driver 71 drives the unloading paper board 6 to move vertically downward so that the unloading paper board 6 abuts the upper surface of the synchronous belt 4, and then the driving component 72 drives the paper unloading platform 1 to move horizontally in the opposite direction. At this time, the unloading paper board 6 can block the paper and make the paper fall on the tray 8.

[0032] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
