Obviously, the accompanying drawings described below are only one embodiment of the present invention. For those of ordinary skill in the art, without creative efforts, according to this drawing and embodiment, obtaining other embodiments all belong to the protection scope of the present invention.

[0021] According to Figures 1-5 As shown, a waste paper collection device for a paper cutting machine includes a feed hopper 1. The bottom of the feed hopper 1 is fixedly installed with a storage bin 2. The bottom of the storage bin 2 is fixedly installed with a discharge hopper 3. A pressing plate 4 is movably installed in the discharge hopper 3. A motor 5 is installed on the periphery of the discharge hopper 3 for driving the pressing plate 4 to move. A baffle plate 6 is movably installed at the bottom of the discharge hopper 3, and a pressure sensing mechanism is arranged at the top of the baffle plate 6.

[0022] In this embodiment, the discharge hopper 3 is a funnel-shaped structure with a wider top and a narrower bottom. A pressing chamber 31 is provided at the bottom end of the discharge hopper 3. The size of the pressing plate 4 matches that of the pressing chamber 31. A connecting seat 7 is fixedly installed at the center of the top of the pressing plate 4. A connecting rod 8 is hingedly installed on the connecting seat 7. The front and rear sides of the end of the connecting rod 8 away from the connecting seat 7 are hingedly installed with a crank 9. The end of the rotating shaft of the crank 9 is rotatably installed with a bearing seat 10. The bearing seat 10 is fixedly installed on the outer wall of the discharge hopper 3. A fixed frame 11 is fixedly installed on the periphery of the discharge hopper 3. The motor 5 is fixedly installed on the fixed frame 11 through a motor bracket. The power output shaft of the motor 5 is connected to the rotating shaft of the crank 9 through a coupling. Guiding surfaces 41 are provided on the left and right sides of the top of the pressing plate 4. The outer ends of the guiding surfaces 41 are inclined towards the bottom end of the discharge hopper 3. Guide rods 12 are fixedly installed at the four end points of the top of the pressing plate 4. Guide seats 13 are slidably installed on the guide rods 12. The guide seats 13 are fixedly installed on the inner side wall of the discharge hopper 3. The waste paper strips in the storage bin 2 fall onto the top of the pressing plate 4 under the action of gravity and slide to both sides of the pressing plate 4 under the guidance of the guiding surfaces 41. By driving the crank 9 to rotate through the motor 5, the pressing plate 4 reciprocates up and down in the discharge hopper 3 along the guide rods 12 under the cooperation of the crank 9 and the connecting rod 8. Under the impact of the pressing plate 4, the waste paper strips are dispersed from each other to facilitate entry into the pressing chamber 31.

[0023] In this embodiment, the pressure sensing mechanism includes a bearing plate 14. Elastic telescopic rods 15 are fixedly installed at the four end points of the bottom of the bearing plate 14. The elastic telescopic rods 15 are fixedly installed on the material baffle 6. A pressure sensor 16 is provided between the material baffle 6 and the bearing plate 14. The pressure sensor 16 is fixedly installed on the material baffle 6. When the waste paper strips are pressed tightly, the bearing plate 14 is pressed downward, and the movable rods of the elastic telescopic rods 15 are compressed downward accordingly. The elastic telescopic rods 15 play a role of buffering and supporting the bearing plate 14, reducing the impact force received by the pressure sensor 16.

[0024] In this embodiment, the end of the material baffle 6 is hinged to the rear end of the bottom of the material pressing cavity 31. Electric telescopic rods 17 are provided on the left and right sides of the material pressing cavity 31.

The end of the electric telescopic rod 17 far away from the material baffle 6 is hinged and installed at the front end of the top of the material pressing cavity 31. The material baffle 6 is driven by the electric telescopic rod 17 to turn downward and open so as to discharge and collect the waste paper strips from the equipment outward.

[0025] When the present utility model is in use, the waste paper strips cut by the paper cutting machine are put into the storage box 2 through the feeding hopper 1. Then, the motor 5 is started. The motor 5 drives the crank 9 to rotate. Under the cooperation of the crank 9 and the connecting rod 8, the pressing plate 4 reciprocates up and down in the blanking hopper 3 along the guide rod 12. Under the action of the pressing plate 4, the waste paper strips stacked in the storage box 2 enter the material pressing cavity 31, and the waste paper strips in the material pressing cavity 31 are extruded by the pressing plate 4. When the waste paper strips are pressed tightly, the bearing plate 14 is pressed downward. The pressure sensor 16 senses the pressure received by the bearing plate 14. When the pressure reaches the set value, the motor 5 stops running and the pressing plate 4 is located in the material pressing cavity 31. At the same time, the push rod of the electric telescopic rod 17 extends to drive the material baffle 6 to turn downward and open. After the material baffle 6 is opened, the waste paper in the material pressing cavity 31 is discharged outward for collection. The waste paper strips are compressed to reduce the volume, reducing the space required for collecting waste paper, reducing the consumption of manpower and time, and effectively improving the work efficiency.
