DETAILED DESCRIPTION

[0020] Reference Figures 1 to 4 The embodiments of the utility model are further described.

[0021] A paper receiving device of an offset printing machine comprises an offset printing machine body 3, a bracket 2, a material receiving box 1, a moving device 8, a first hydraulic cylinder 10, a second hydraulic cylinder 11 and a positioning plate 14. The bracket 2 is provided under the material receiving box 1, and a feeding port is provided on the material receiving box 1. The offset printing machine body 3 transmits the processed paper to the material receiving box 1 through the feeding port. When the material receiving box 1 is full, the positioning plate 14 is rotated from the material receiving box 1 to expose the inside of the material receiving box 1, and then the moving device 8 is driven to move upward by starting the first hydraulic cylinder 10 and the second hydraulic cylinder 11, and then the paper accumulated in the material receiving box 1 is lifted up by the moving device 8, and then all the paper is taken out of the material receiving box 1 at one time. When there is accumulated paper in the material receiving box 1 and there is no need to raise the moving device 8 by the first hydraulic cylinder 10 and the second hydraulic cylinder 11, the moving device 8 is manually moved to take the paper accumulated in the material receiving box 1 out of the material receiving box 1.

[0022] The moving device 8 includes a limiting plate 81, a first fixed plate 82, a second fixed plate 83, a first limiting block 84 and a second limiting block 85. The limiting plate 81 is above the material receiving box 1 and contacts the material receiving box 1. A first handle 9 is provided on the limiting plate 81. A first slide groove 4 and a second slide groove 5 are provided on the material receiving box 1. One end of the first fixed plate 82 and the second fixed plate 83 are fixedly connected to the bottom of the limiting plate 81. The other ends of the first fixed plate 82 and the second fixed plate 83 extend into the first slide groove 4 and the second slide groove 5 respectively. The bottom of the material receiving box 1 has two first limiting grooves 6 and second limiting grooves 7 respectively connected to the first slide groove 4 and the second slide groove 5. Limiting blocks are provided in the first limiting groove 6 and the second limiting groove 7. The limiting block in the first limiting groove 6 is fixedly connected to the first fixed plate 82. The limiting block in the second limiting groove 7 is fixedly connected to the second fixed plate 83. Positioning blocks are provided in the first slide groove and the second slide groove.

[0023] After the paper printed by the offset printing machine body 3 is transferred into the receiving box 1, the first handle 9 is pulled so that the first handle 9 drives the limiting plate 81 to move upward, and the limiting plate 81 drives the first fixed plate 82 and the second fixed plate 83 to move in the first chute 4 and the second chute 5 respectively, and then the first fixed plate 82 and the second fixed plate 83 drive the first limiting block 84 and the second limiting block 85 to move upward, and then the paper accumulated in the receiving box 1 is lifted by the first limiting block 84 and the second limiting block 85, and then the paper is moved away from the bottom of the receiving box 1, so that the paper can be taken out of the receiving box at one time. 1, and it will not be difficult to take out due to the paper sticking to the bottom of the receiving box 1, thereby improving the work efficiency. At the same time, by providing the positioning blocks, when the first fixing plate 82 and the second fixing plate 83 move in the first chute 4 and the second chute 5 and are about to slide out of the first chute 4 and the second chute 5, the first limit block 84 and the second limit block 85 will conflict with the positioning blocks 19 in the first chute 4 and the second chute 5, and then the positioning blocks 19 play a limiting role, preventing the limit plate 81 from rising too high and moving the first limit block 84 and the second limit block 85 out of the receiving box 1.

[0024] The receiving box 1 is also provided with a through slot 12, a positioning plate 14 is hinged to the receiving box 1 and the positioning plate 14 is placed in the through slot 12, a second handle 18 is provided on the positioning plate 14 and an observation window 17 is embedded on the positioning plate 14 for conveniently observing the number of papers placed inside the receiving box 1, first magnets 15 are embedded on both sides of the positioning plate 14, and second magnets 16 that are mutually attracted to the first magnets 15 are embedded on the inner walls of both sides of the through slot 12.

[0025] After lifting the paper from the receiving box 1 by the moving device 8, the second handle 18 is held to rotate the positioning plate 14 out of the through slot 12, so that the first magnet 15 and the second magnet 16 are separated from each other, so that the interior of the receiving box 1 is exposed through the through slot 12, and then the hand is inserted into the receiving box 1 through the through slot 12 to take out the paper lifted by the moving device 8 from the receiving box 1, so as to achieve one-time removal of the paper, and the paper at the bottom will not stick to the receiving box 1 and become difficult to take out. After taking out the paper, the positioning plate 14 is rotated into the through slot 12 again, and the first magnet 15 and the second magnet 16 are adsorbed to each other to fix the positioning plate 14 in the through slot 12.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
