[0002] Paper unloaders are mainly used in the printing industry to automatically process large amounts of paper. They can significantly improve production efficiency and the continuity of the work process. The traditional way of unloading paper is usually manual unloading. After the paper is cut, it is manually carried by employees. During the handling process, the paper is easy to scratch the employees and increase the labor of the employees. Therefore, paper unloaders are generally used to carry paper.

[0003] In the process of unloading and transporting the paper, the existing paper unloader needs to fix the paper on the tray, so the side baffles on the paper unloader will squeeze the paper to arch or bend downward, causing damage to the outermost part of the paper.

[0023] The paper pile fixing and leveling mechanism 300 includes: a left baffle 310, a right baffle 320, a first baffle frame 330, a second baffle frame 340, a roller 350, a roller mounting frame 360, a sleeve 370, a spring seat 380, a spring 390 and a fixing member 3100. The left baffle 310 is connected to the mounting bracket 100 through the first baffle frame 330, the right baffle 320 is connected to the mounting bracket 100 through the second baffle frame 340, the roller mounting frame 360 ​​is connected to the second baffle frame 340, both ends of the roller 350 are connected to the sleeve 370, the sleeve 370 is connected to the spring seat 380, the spring 390 is arranged in the spring seat 380, the spring 390 is connected to the sleeve 370, the fixing member 3100 is connected to the outer side of the sleeve 370, and the spring seat 380 is connected to the roller mounting frame 360.

[0024] A transverse track plate 110, a first vertical track 120 and a second vertical track 130 are provided on the mounting bracket 100. The transverse track plate 110 is connected to the mounting bracket 100. The transverse track plate 110 is connected to the paper unloading mechanism 200. The right end of the transverse track plate 110 is connected to the driving device 500. The first vertical track 120 and the second vertical track 130 are provided on the transverse track plate 110. The first vertical track 120 is movably connected to the left baffle 310 through the first baffle frame 330. The second vertical track 130 is movably connected to the right baffle 320 through the second baffle frame 340.

[0025] The paper unloading mechanism 200 includes: a connecting plate 210, a movable plate 220 and a paper unloading inclined plate 230. The connecting plate 210 is movably connected to the transverse track plate 110, the movable plate 220 and the paper unloading inclined plate 230 are fixedly connected to the connecting plate 210, and the paper unloading inclined plate 230 is connected to one side of the movable plate 220.

[0026] The principle of the utility model is that the paper cut on the paper cutter is placed on the moving plate 220 of the paper unloading mechanism 200, the moving plate 220 and the paper unloading inclined plate 230 are installed on the connecting plate 210, and the connecting plate 210 is controlled by the driving device 500 to move on the transverse track plate 110. Before the equipment is started, the height of the paper pile is measured by the laser rangefinder 400, and the data is transmitted to the PLC control panel 600, and then the left baffle 310 and the first baffle frame 330 are raised to a suitable height, so that the moving plate 220 and the paper pile can move horizontally from under the left baffle 310, and the height of the right baffle 320 and the roller mounting frame 360 ​​are adjusted to make the height of the roller 350 match the height of the top layer of the paper pile. After the equipment is started, the driving device 500 controls the connecting plate 210 to move the movable plate 220 and the paper unloading inclined plate 230 horizontally across the left baffle 310 to the position of the right baffle 320. During the movement, the top layer of the paper pile on the roller 350 is leveled from right to left. During the leveling process, the roller 350 is connected to the shaft sleeve 370 and can move freely. The roller 350 is acted upon by the spring seat 380 and the spring 390 and can move elastically up and down in the opening of the spring seat 380, thereby reducing the damage caused by the force on the roller 350 and the roller mounting frame 360 ​​and providing compensation space for the roller 350 to be leveled. At the same time, the left baffle 310 is controlled to move down to the same horizontal position as the right baffle 320, and then the first vertical track 120 is moved right so that the left baffle 310 and the right baffle 320 clamp the two sides of the paper pile. Since the roller 350 presses the upper part of the paper pile, the paper pile will not bend. Finally, the movable plate 220 is controlled to move with the connecting plate 210, and the paper pile slides down from the paper unloading inclined plate 230 at the right end of the movable plate 220 onto the transport pallet, completing the paper unloading operation.

[0027] The utility model adds a fixed leveling mechanism, which can level and press the top of the paper pile to prevent the paper from bending or becoming scattered when the baffle clamps the paper pile, and installs a spring compensation component in the leveling roller to improve the stability of the leveling roller and avoid damaging the paper surface.

[0028] The specific implementation modes of the present invention are described above, but the present invention is not limited thereto. The present invention can also have various changes without departing from the purpose of the present invention.
