[0001] The utility model relates to the technical field of paper separation, in particular to a paper separation device. Background Art

[0002] With the rapid development of information technology, paper is still widely used, especially in the fields of office, printing and packaging. The efficient processing and utilization of paper has become an important part of improving production efficiency and reducing costs. Cartons, as an important packaging material, are widely used in logistics, transportation and storage. Its production process requires efficient and precise processing of paper. The production of cartons usually involves multiple links, including paper cutting, forming, gluing and pressing. In this process, the separation and transportation of paper sheets are crucial links, which directly affect the production efficiency and product quality of cartons. Therefore, a paper sheet separation device is needed.

At this time, the two baffles 23 are in contact with the top of the piece of paper until the piece of paper and the two baffles 23 are separated. At this time, the two baffles 23 return to their original state and contact the other end of the piece of paper. At this time, the screw sleeve 8 is located at the end of the reciprocating screw 7, and the reciprocating screw 7 continues to rotate, driving the screw sleeve 8 to move in the opposite direction, and then driving the connecting seat 4 to move in the opposite direction. Under the action of the two baffles 23, the piece of paper and the top plate 12 are gradually separated until the piece of paper and the top plate 12 are completely separated, thereby realizing the separation of the paper.

A synchronous belt 16 is provided at the bottom of the operating table 1, and the two ends of the synchronous belt 16 are respectively sleeved on the side walls of the two synchronous wheels 15. By rotating one of the threaded rods 14 to cooperate with the synchronous belt 16 and the two synchronous wheels 15, the other threaded rod 14 is driven to rotate simultaneously. The two threaded rods 14 rotate to cooperate with the two threaded holes and the two sliders 13 to drive the top plate 12 to rise and fall along the inner wall of the placement groove 10. The distance between the top plate 12 and the bottom of the rectangular tube 3 can be adjusted. At this time, the distance between the top plate 12 and the bottom of the slider 13 is the thickness of the paper sheet, so that paper sheets of different thicknesses can be separated without changing equipment, thereby improving the practicality of the device.

[0024] Reference Figure 1 and Figure 4In a preferred implementation, the extrusion mechanism includes two slide rods 17, which are respectively fixed to the two ends of the top of the portal frame 2.

[0025] With reference to Figure 1 In a preferred implementation, the one end of the side wall of the operation table 1 is inclinedly fixed with a guide plate 5. The separated paper sheet slides through the guide plate 5 and can be poured into the top of the external conveying mechanism and transported to the designated place.

[0026] The working principle of this embodiment: During use, a conveying mechanism is connected to the bottom of the guide plate 5. By rotating one of the threaded rods 14, the synchronous belt 16 and the two synchronous wheels 15 drive the other threaded rod 14 to rotate simultaneously. The two threaded rods 14 rotate to cooperate with the two threaded holes and the two sliders 13 to drive the top plate 12 to rise and fall along the inner wall of the placement groove 10, and the distance between the top plate 12 and the bottom of the rectangular tube 3 can be adjusted. At this time, the distance between the top plate 12 and the bottom of the slider 13 is the thickness of the paper sheet, so that paper sheets of different thicknesses can be separated without replacing equipment, which improves the practicality of the device.

In the reverse direction of the two compressed springs 18 Under the action, the connecting rod 20 and the squeezing plate 21 are driven to move downward at the same time. At this time, the paper is in a compressed state, and the paper at the bottom end of the rectangular tube 3 contacts the top of the top plate 12. At this time, the reciprocating screw 7 continues to rotate to drive the connecting seat 4 to continue to move, thereby driving the paper to move. When the paper moves, one end of the paper contacts the two baffles 23 and squeezes the two baffles 23 to make circular motions with the two U-shaped frames 22 respectively. At this time, the two baffles 23 are in contact with the top of the paper until the paper and the two baffles 23 are separated. At this time, the two baffles 23 returns to its original shape and contacts the other end of the paper. At this time, the screw sleeve 8 is located at the end of the reciprocating screw 7. The reciprocating screw 7 continues to rotate, driving the screw sleeve 8 to move in the opposite direction, and then driving the connecting seat 4 to move in the opposite direction. Under the action of the two baffles 23, the paper and the top plate 12 are gradually separated until the paper and the top plate 12 are completely separated. At this time, the paper slides to the top of the conveying mechanism under the action of gravity and is transported to the designated location with the help of the guide plate 5, thereby realizing the separation of the paper. There is no need for manual separation, which saves time and improves work efficiency.
