[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0022] The utility model provides a technical solution: Figure 1 and Figure 4 As shown, in this embodiment, a receiving device for unloading materials from an offset printing machine includes a support frame 1, a conveying frame 2 is fixedly connected to the top of the support frame 1, a transmission belt 5 is rotatably connected to the inside of the conveying frame 2, a dryer 4 is fixedly connected to the top of the conveying frame 2, a fixed frame 3 is fixedly connected to the inside of the support frame 1, an adjusting structure 7 is provided in the fixed frame 3, a plurality of connecting plates 9 are connected to one side of the adjusting structure 7, a receiving plate 10 is fixedly connected to one side of the connecting plate 9, a collecting box 11 is overlapped on the top of the receiving plate 10, the receiving plate 10 is externally connected to a limiting structure 8, the limiting structure 8 is connected to the collecting box 11, the adjusting structure 7 includes a toothed disk 1 701, an anti-skid disk 702 and a motor 704, a toothed disk 2 706 is fixedly connected to one side of the anti-skid disk 702, a roller chain 705 is meshed on the outside of the toothed disk 1 701, and the output shaft of the motor 704 is transmission-connected to an anti-skid belt 703.
[0023] like Figure 1 and Figure 3 As shown, a feed port 6 is provided in the conveying frame 2, and a collecting box 11 is overlapped at the bottom of the conveying frame 2. The collecting box 11 is located below the feed port 6. The top of the collecting box 11 is provided with an arc shape, so that the collecting box 11 can perfectly fit with the bottom of the conveying frame 2 through the arc shape above after rotation, thereby avoiding the phenomenon of paper offset during unloading. The toothed disk 1 701 is rotatably connected to the top of the fixed frame 3, the anti-skid disk 702 is rotatably connected to the bottom of the conveying frame 2, the motor 704 is fixedly connected to the front of the fixed frame 3, the connecting plate 9 is fixedly connected to the roller chain 705, the toothed disk 1 701 is meshed with the toothed disk 2 706 through the roller chain 705, and the motor 704 is connected to the anti-skid disk 702 through the anti-skid belt 703.
[0024] By setting the anti-slip belt 703, when the output shaft of the motor 704 rotates, since the motor 704 is connected to the anti-slip disk 702 through the anti-slip belt 703, the toothed disk 2 706 and the output shaft of the motor 704 can achieve the function of synchronous rotation, which helps to maintain the dynamic balance of the device, reduce vibration, and improve the stability of operation.
[0025] like Figure 4As shown, the collection box 11 is connected to a limiting plate 12 on the outside, and the limiting plate 12 is clamped in the receiving plate 10. The limiting structure 8 includes a sleeve plate 801 and a recessed plate 802. The sleeve plate 801 is fixedly connected to the side of the receiving plate 10, and the recessed plate 802 is fixedly connected to the side of the collection box 11. A guide rod 803 is rotatably connected in the sleeve plate 801, and a rotating plate 804 is fixedly connected to the outside of the guide rod 803. A clamping plate 805 is slidably connected in the rotating plate 804, and a spring 806 is provided under the clamping plate 805. The clamping plate 805 is connected to the rotating plate 804 through the spring 806, and the clamping plate 805 is clamped in the recessed plate 802.
[0026] By setting the limiting plates 12, when the collecting box 11 is installed with the receiving plate 10, the collecting box 11 will be clipped into the receiving plate 10 through the limiting plates 12 on both sides, so that the limiting plates 12 play a certain auxiliary role in fixing the collecting box 11, avoiding the position displacement of the collecting box 11 when limiting, and ensuring the applicability of the receiving device.
[0027] The utility model provides a receiving device for blanking of an offset printing machine, and the specific working principle is as follows:
[0028] When the receiving device is collecting the papers in a centralized manner, the collection box 11 is clamped into the receiving plate 10 through the limiting plate 12, and then a pulling force is applied to the clamping plate 805. When the clamping plate 805 slides in the rotating plate 804, the spring 806 is deformed, and the rotating plate 804 is flipped with the guide rod 803 as the center. When the rotating plate 804 is clamped into the concave plate 802, the clamping plate 805 is released, and the clamping plate 805 is reset by the spring 806. After reset, the clamping plate 805 is clamped into the concave plate 802.
[0029] When the offset printing machine finishes unloading the paper, the paper will fall onto the top of the conveyor belt 5, and then the paper will be slowly transported by the conveyor belt 5. When the paper moves under the dryer 4, the dryer 4 will dry the surface of the paper, and the paper will fall into the collection box 11 through the feed port 6, and then the anti-slip belt 703 is driven by the motor 704 to rotate. Since the motor 704 is connected to the anti-slip disk 702 through the anti-slip belt 703, the toothed disk 2 706 will rotate with the output shaft of the motor 704. Since the roller chain 705 is engaged with the toothed disk 1 701 and the toothed disk 2 706, the roller chain 705 will roll on the surface of the toothed disk 2 706, and then another collection box 11 on the side of the roller chain 705 is overlapped under the conveyor frame 2. Since the dryer 4 and the conveyor belt 5 are well-known equipment purchased directly on the market by those skilled in the art, we only use them here and have not made any structural and functional improvements to them. We will not go into details here.
[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
