Referring to fig. 1 to 3, the present invention relates to a paper scrap sweeping and pressing device 100 and a paper shredder using the paper scrap sweeping and pressing device 100, wherein the paper scrap sweeping and pressing device 100 is disposed in a paper shredder case 200, is located below a paper shredder core, and is rotatably extended into a paper scrap barrel 300 to act on paper scraps in the paper scrap barrel 300, so that the acted paper scraps are moved from a paper scrap stacking position (generally, a position corresponding to a paper outlet of the paper shredder core) in the paper scrap barrel 300 to an idle position in the paper scrap barrel 300, thereby improving the utilization rate of a space in the paper shredder paper scrap barrel 300 and also improving the paper shredding efficiency of automatic paper shredding.
The paper scrap sweeping and pressing device 100 comprises a mounting plate, a driving motor 10, a swinging mechanism, a sweeping and pressing plate 30, a full paper detection switch 50 and an initial position detection switch 60; the mounting plate is used for mounting the paper scrap sweeping and pressing device 100 into a case 200 of the paper shredder, is positioned below a paper shredder core and is provided with an avoiding structure for paper scrap to fall; the swinging mechanism is connected with the driving motor 10 and the sweeping and pressing plate 30 so as to drive the sweeping and pressing plate 30 to swing under the action of the driving motor 10; the sweeping and pressing plate 30 is used for pushing paper scraps to move when the sweeping and pressing plate swings; the paper full detection switch 50 is used for detecting the height of paper scraps in the paper scrap barrel 300, and starting the driving motor 10 to drive the sweeping and pressing plate 30 to swing when the height of accumulated paper scraps reaches a set value; the initial position detection switch 60 is used to detect the initial position of the platen 30.
The driving motor 10 has an automatic reverse rotation function, and automatically reverses when the reaction force of the paper scraps on the sweeping and pressing plate 30 is greater than a set value, so that the sweeping and pressing plate 30 can swing back and forth to push the paper scraps to move, and the paper scraps are compacted downwards.
Sweep clamp plate 30 including sweeping splenium 32 and installation department 31, sweep and be equipped with the hole of stepping down 33 that the paper feed bits dropped between splenium 32 and the installation department 31, sweep splenium 32 and installation department 31 through injection molding technology integrated into one piece, the hole of stepping down 33 just is to the exit slot of shredded paper core when sweeping splenium 32 and being located initial position.
It should be understood that, as the paper scraps are compacted continuously, the reaction force of the paper scraps on the paper sweeping board increases as the number of times of paper sweeping increases, and preferably, the plurality of comb teeth 321 are equidistantly arranged at the paper sweeping part 32, so as to reduce the reaction force generated by the paper scraps when the paper sweeping operation of the paper sweeping pressure plate 30 is performed, which can ensure the smooth performance of the paper sweeping operation and also can reduce the power of the motor. Therefore, when the driving motors 10 with the same power are used, the paper sweeping times of the sweeping pressing plate 30 with the comb teeth 321 are more than that of the flat sweeping pressing plate, and the paper shredding efficiency is further improved. Optionally, each of the comb teeth 321 includes an anti-stagnation block 3211 and a paper pushing block 3212 which are coplanar and connected, the anti-stagnation block 3211 is a semi-cylindrical block, and at least an end of one side of the paper pushing block 3212, which is back to the anti-stagnation block 3211, which is far away from the mounting portion 31 is arc-shaped.

In one embodiment, the paper pushing block 3212 is provided with a groove, the groove extends in the direction of the paper pushing block 3212 toward the anti-stagnation block 3211, and by providing the groove, shrinkage deformation of the comb teeth 321 during injection molding can be prevented, and the glue position thickness can be set conveniently during mold opening.
One side of installation department 31 keeping away from installation department 31 establishes to circular-arc, and installation department 31 has seted up pivot mounting hole (not marking, the same time down) and gear mounting hole (not marking, the same time down), wears to be equipped with pivot 310 in the pivot mounting hole, gear mounting hole and pivot mounting hole intercommunication. The end of the rotating shaft is connected with the mounting plate through a rotating shaft pressing block 40 and can rotate relative to the mounting plate. In addition, the pivot is equipped with two flat positions, the pivot mounting hole correspondence is equipped with two flat positions to avoid the relative installation department 31 of pivot to rotate.
In one embodiment, the swing mechanism includes a first bevel gear 21 and a second bevel gear 22 engaged with each other, the first bevel gear 21 is connected to an output shaft of the driving motor 10, and the second bevel gear 22 is sleeved on the rotating shaft and embedded in the gear mounting hole. Thereby, the first bevel gear 21 is rotated by the driving motor 10, and the sweeping platen 30 is rotated by the second bevel gear 22.
In another embodiment, the swing mechanism is formed by a worm gear and a worm, wherein the worm gear is connected to the driving motor 10, and the worm is connected to the mounting portion 31 of the sweeping pressure plate 30.
The initial position detection switch 60 includes a stationary contact and a movable contact, and the movable contact is in contact with the stationary contact when the wiping portion 32 of the wiping plate 30 is located at the initial position.
In one embodiment, the mounting portion 31 is provided with an initial position ramp 311, the initial position ramp 311 extends along the circular arc side of the mounting portion 31, and the distance between the inclined surface of the ramp and the axis of the mounting portion 31 increases in the counterclockwise direction. The initial position inclined block 311 rotatably presses the movable contact to be in contact with the stationary contact, thereby completing the circuit of the initial position detecting switch 60 and recognizing that the sweeping pressure part 32 of the sweeping pressure plate 30 is returned to the initial position. That is, when the initial position inclined block 311 rotates to the highest point to contact with the movable contact, the movable contact contacts with the fixed contact, and when the initial position inclined block 311 rotates from the highest point to the lowest point, the pressure of the inclined block on the movable contact is gradually reduced.
This sweep and press wastepaper device is exactly at the shredded paper in-process, and the suggestion back is full to the paper appears, and automatic start sweeps and presses work, sweeps the action of pressing to the accumulational wastepaper of exit slot, sweeps the wastepaper to the position of wastepaper bucket other few papers, carries out the action of pushing down simultaneously, just so can continue the shredded paper, can carry out once more when paper is full once more and sweep and press the wastepaper action, and the wastepaper can't sweep again and press the wastepaper till wastepaper bucket fills with the wastepaper completely. Through implementing this sweeping and pressing wastepaper device, reducible user takes out the action that the bucket pressed paper, has also reduced the excessive pollution to office environment of wastepaper dust, has also improved shredded paper efficiency simultaneously, can let the consumer on basically not increasing how much cost basis, use this technique, improved user's experience and felt, also improved work efficiency.
The above example is an automatic paper scrap sweeping and pressing mode, the paper scrap sweeping and pressing device of the utility model can also be set in a manual mode, and the working state of the paper scrap sweeping and pressing device is controlled by a switch button arranged at the top end of the case of the paper shredder, so that different experiences are provided for users.
