Description
Technical Field
The utility model relates to a kneader especially relates to an automatic kneader with energy-conserving effect.
Background
Shredder for shredding paper is known, which works by passing a plurality of cutting blades (spaces) through two parallel and relatively rotating shafts (rotating blades) with a motor and gear unit (motor and gear box) driving the shafts to cut the paper into strips. In order to protect the motor of the paper shredder from being damaged by overload, there is a limit to the maximum sheet feeding (sheet capacity) per time, i.e. when most of the paper needs to be destroyed, the user must manually shred the paper in batches below the maximum sheet feeding per time, which is a tedious and time-consuming process. In order to meet the demand of shredding paper in large quantities, a paper shredder with an automatic paper feeding function, called an automatic paper shredder (auto fed shredder) is developed accordingly.
For example, in U.S. patent No. 9,884,323 shown in fig. 1A and 1B, when the flip-top lid 14 of the automatic shredder is opened, a container (feeder base or matched) 34 is exposed to accommodate a standard stack of paper sheets (stack of sized paper sheets), a paper slot (feeder slot)28 is located in the middle of the bottom of the container 34, and paper passing through the paper slot 28 activates a shredder mechanism (shredder mechanism)36 below the paper slot to cut the paper sheets into pieces and fall into a waste bin (waste bin). The bottom surface of the liftable upper cover 14 is provided with a paper pressing mechanism (32), and when the liftable upper cover 14 is closed, the paper pressing mechanism 32 presses the laminated paper placed in the accommodating groove; the paper feeding slot 28 is provided with feeding mechanisms (feeding mechanisms) 30 on both sides thereof, which may be a plurality of sets of rollers (roller rollers) arranged symmetrically, but may also be a roller-belt combination (roller-belt combination), and the feeding mechanisms 30 are used for contacting the bottom of the stacked paper sheets in the accommodating slot 34, and capturing and pulling the bottom paper sheet to be folded above the paper feeding slot 28 and clamping the bottom paper sheet to the shredding mechanism 36 below, and capturing, pulling, folding and clamping the new bottom paper sheet by the feeding mechanisms until all the paper sheets are shredded.
An automatic shredder having the similar functions as described above is disclosed in U.S. Pat. No. 7,387,268 shown in fig. 2, U.S. Pat. No. 7,658,342 shown in fig. 3, and U.S. Pat. No. 8,336,794 shown in fig. 4.
Please refer to fig. 5, aboveThe conventional automatic shredder has a common point that the paper feeding slot 28 in the middle of the receiving groove 34 and the folding line P of the long sides L of the stacked paper P placed in the receiving groove 34yNear parallel (near parallel orientation) such that the long side L of the stacked sheets P is captured, pulled, folded, and pinched by the sheet feeding mechanism 12. In other words, the travel of the sheet to be shredded captured at the lowermost part of the stacked sheet P through the shredder mechanism (not shown) is half of the long side of the sheet to be shredded (1/2L); taking the long side 29.7 cm of a4 for example, the length after folding is about 15 cm, so the time required for the shredder to cut 1/2L, i.e., 15 cm, is the time required for the shredder to cut a4 of paper.
In summary, the time required for the shredder mechanism to cut the paper to be shredded is directly proportional to the travel of the paper through the shredder mechanism after it has been folded. In other words, the shorter the travel of the folded paper to be shredded through the shredding mechanism, the shorter the shredding time, and as a result, the cumulative effect will significantly reduce the operating time of the motor, achieving the energy saving effect.
SUMMERY OF THE UTILITY MODEL
The main object of the present invention is to provide an automatic paper shredder with energy saving effect, which makes the paper feeding slot and the folding line of the short edge of the stacked paper placed in the storage tank nearly parallel, so that the short edge of the stacked paper is captured, pulled, folded and clamped by the paper feeding mechanism to the shredding mechanism.
The technical scheme is as follows: to achieve the above object, the present invention provides an automatic paper shredder with energy saving effect, which comprises a liftable top cover equipped with a paper pressing device, a containing groove exposed after the liftable top cover is lifted for placing stacked paper, a paper feeding slot in the middle of the containing groove, paper feeding mechanisms at two sides of the paper feeding slot, and a shredding mechanism below the paper feeding slot, wherein the paper feeding slot is arranged in the paper feeding mechanism; when the upper cover is closed, the paper pressing device presses the laminated paper in the accommodating groove, the paper feeding mechanisms which move relatively at two sides of the paper feeding slot capture and pull the bottom paper of the pressed laminated paper, the paper is folded towards the paper feeding slot and clamped to the shredding mechanism, and the new bottom paper is captured, pulled, folded and clamped by the paper feeding mechanisms until all the laminated paper is shredded; the paper feeding slot is approximately parallel to the folding line of the short edge of the stacked paper placed in the containing groove, so that the short edge of the stacked paper is captured, pulled, folded and clamped to the shredding mechanism by the paper feeding mechanism.
The automatic paper shredder with the energy-saving effect comprises a liftable upper cover provided with a paper pressing device, a containing groove which is used for placing the stacked paper and is exposed after the liftable upper cover is lifted, a paper feeding slot in the middle of the containing groove, paper feeding mechanisms on two sides of the paper feeding slot and a shredding mechanism below the paper feeding slot; when the liftable upper cover is closed, the paper pressing device presses the laminated paper in the accommodating groove, the paper feeding mechanism which moves relatively at two sides of the paper feeding slot captures and pulls the bottom paper of the pressed laminated paper, the paper is folded towards the paper feeding slot and is clamped and sent to the cutting mechanism, and the new bottom paper is captured, pulled, folded and clamped and sent by the paper feeding mechanism until all the laminated paper is cut; the paper feeding slot is characterized in that a deflection angle theta is formed between the paper feeding slot and a short edge folding line of the short edges of the stacked paper placed in the containing groove under pressure, so that the short edges of the stacked paper are captured, pulled, folded and clamped to the shredding mechanism by the paper feeding mechanism.
Because the paper feeding slot is designed deliberately to be nearly parallel to the folding line of the short edge of the laminated paper placed in the containing groove, the short edge of the laminated paper is captured, pulled, folded and clamped to the shredding mechanism by the paper feeding mechanism; taking the short side 21 cm of A4 as an example, the folded length is 10.5 cm, so the time for shredding one A4 paper is the time required for the shredder to cut one half (1/2W) of the short side of A4, i.e., 10.5 cm.
Compared with the conventional automatic paper shredder, the paper feeding slot is almost parallel to the folding line of the long edge of the laminated paper placed in the accommodating groove, and the long edge of the laminated paper is captured, pulled, folded and clamped to the shredding mechanism by the paper feeding mechanism; the utility model designs the paper feeding slot to be almost parallel to the short edge folding line of the laminated paper placed in the containing groove, so that the short edge of the laminated paper is captured, pulled, folded and clamped by the paper feeding mechanism to the shredding mechanism; taking a4 paper as an example, the cutting stroke of a traditional automatic shredder is 15 cm, while the utility model is obviously 10.5 cm shorter. Therefore, shredding one sheet of A4 paper would save about 25% of the time.
