Detailed Description
Embodiments of the present invention are further described below with reference to the accompanying drawings.
As shown in fig. 1-5, the present embodiment relates to an auxiliary paper feeding device for a scanner, which includes a paper feeding platform 1, and paper feeding baffles 2 are disposed on both left and right sides of the paper feeding platform 1.
In this embodiment, the paper feeding baffle 2 is provided with a paper pressing sheet 3. Through pressing the paper 3, combine paper feed baffle 2 again and carry out a preliminary spacing pressfitting with paper both ends, prevent that whole pile of more soft paper from collapsing at scanning paper feed in-process.
Wherein, press the paper piece 3 embedded in the 2 inside walls of paper feed baffle to it is articulated with the 2 inside walls of paper feed baffle. Through the design, when the common paper is scanned, the paper pressing sheet 3 can be accommodated in the paper feeding baffle 2; the paper pressing sheet 3 is opened when the soft paper is limited, and the operation is convenient.
Specifically, the method comprises the following steps: in order to avoid the paper feed of waiting to scan the paper of putting at paper feed platform 1 in the interference of the pressure paper piece 3 of getting up, it has the caulking groove to open on the lateral wall that paper feed baffle 2 corresponds pressure paper piece 3, the bottom side limit integrated into one piece of pressure paper piece 3 has hollow spliced pole, and the hinge interface has all been opened at the both ends of this spliced pole, the caulking groove corresponds hinge interface department integrated into one piece and has the hinge post, press the hinge interface that paper piece 3 passes through the spliced pole, the hinge post can turn over to roll over and articulate in the caulking groove, through pressing paper piece 3 and articulating in the caulking groove, hide pressure paper board 3 in paper feed baffle 2 when the user need not use pressure paper piece 3, still guarantee the pleasing to the eye.
A return spring is arranged between the hinged opening at one end of the connecting column and the hinged column, and the paper pressing piece 3 is elastically hinged in the caulking groove through the return spring. By arranging the return spring, when the paper pressing sheet 3 is completely opened, the paper pressing sheet 3 can be clamped, and the paper pressing effect of the paper pressing plate 3 is prevented from being influenced by the turning of the paper pressing sheet 3 under the action of paper; when the paper pressing piece 3 is completely folded, the paper pressing piece 3 can be clamped, and the paper pressing piece 3 is prevented from being turned and opened.
In the actual production process, the top end of the paper feeding baffle 2 is provided with a handle groove 21 which is convenient for turning over the paper pressing sheet 3. The paper pressing sheet 3 is convexly provided with a hand breaking part corresponding to the handle groove 21. Thus, the user can easily separate the paper pressing piece 3 from the paper feeding flapper 2 by the handle slot 21 and the hand-severing portion.
In this embodiment, the paper feeding platform 1 is provided with a first paper feeding supporting plate 4 along the paper feeding direction, and the first paper feeding supporting plate 4 is disposed inside the paper feeding platform 1. The first paper feeding supporting plate 4 is convenient to pull out or close back due to the inward-shrinkage arrangement, the operation is convenient, and the occupied space is not too much. Aiming at common paper, the first paper feeding supporting plate 4 can be directly combined in the paper feeding platform 1; if a long sheet needs to be scanned, the first sheet feed tray 4 can be pulled out, so that a long sheet can be set.
When the paper is long, the paper far from the paper inlet will be in close contact with the first paper feeding tray 4, and the friction force is large, so that the paper may not be fed during the scanning process. In this embodiment, a plurality of first pulleys 41 are provided on the top end of the first paper feed tray 4. Through the arrangement of the first pulley 41, the friction force is greatly reduced, the paper feeding is more convenient, and the scanning speed is ensured.
In the actual scanning process, particularly long paper sometimes needs to be scanned, and the requirement cannot be met only by the first paper feeding pallet 4. In this embodiment, the first paper feeding supporting plate 4 is provided with a second paper feeding supporting plate 5, and one end of the first paper feeding supporting plate 4 away from the paper feeding platform 1 along the paper feeding direction is hinged to one end of the second paper feeding supporting plate 5. By the design, the second paper feeding supporting plate 5 can be turned over from the first paper feeding supporting plate 4 through hinging, and the platform for bearing the paper is further prolonged. In order to facilitate the turning of the second paper feeding tray 5, a turning groove 51 is formed in the second paper feeding tray 5. Thus, the user can turn the second sheet feeding tray 5 by holding the turning groove.
Wherein, the included angle formed by the second paper feeding supporting plate 5 and the first paper feeding supporting plate 4 after the second paper feeding supporting plate is overturned is 20-50 degrees. To the overlength paper, second paper feed layer board 5 and first carry out layer board 4 if do not form the contained angle, extend away rather than the coplanar, like this, the paper is easy because of the reason of gravity, can direct butt at the paper feed mouth of scanner, makes the condition of the front end emergence fold of paper easily, is unfavorable for the protection of original file. By forming a certain included angle, the tail end of the overlong paper can slightly droop and hang on the second paper feeding supporting plate 5, and the situation can not occur.
In order to ensure that the second paper feeding tray 5 can scan the paper smoothly, a plurality of second pulleys 52 are disposed on the top and bottom ends of the second paper feeding tray 5 along the paper feeding direction. The first paper feed tray 4 is provided with a plurality of first recesses 42 at an end remote from the hinge for accommodating the second pulleys 52. The first groove 42 can accommodate the second pulley 52, so that the second feeding tray 5 can be accommodated into the feeding platform 1 after being folded.
In this embodiment, in order to reduce the friction between the lowest layer of paper and the paper feeding platform 1, the first paper feeding tray 4 and the second paper feeding tray 5, and facilitate the smooth entering of the paper into the scanner for scanning, some modifications are also made to the paper feeding platform 1, the first paper feeding tray 4 and the second paper feeding tray 5. Wherein, the paper feeding platform 1 is provided with at least one reinforcing rib 11 along the paper feeding direction, and a plurality of paper feeding pulleys 12 are arranged in the reinforcing rib 11. The paper is placed on the paper feeding platform 1, the middle part of the paper is usually tightly abutted to the paper feeding platform due to gravity, and the middle part of the paper is lifted up by arranging the reinforcing ribs 11, so that the paper feeding is facilitated, and the paper feeding process is guaranteed not to be blocked. The first paper feeding supporting plate 4 is provided with a plurality of first reinforcing ribs along the paper feeding direction on one surface abutting against the paper, the function of the first paper feeding supporting plate is the same as that of the reinforcing ribs 11 on the paper feeding platform 1, the middle part of the paper is lifted up, the paper feeding is convenient, and the paper feeding process is guaranteed not to be blocked. The second paper feed supporting plate 5 is also provided with a plurality of second reinforcing ribs along the paper feed direction on one surface abutting against the paper, and the second reinforcing ribs act as the first reinforcing ribs.
The invention has the beneficial effects that: the paper pressing pieces are arranged on the paper feeding baffle plates on the left side and the right side, so that the whole stack of paper can be prevented from collapsing, and a limiting effect is achieved; and the first paper feeding supporting plate is used for lengthening the length of the paper feeding platform, so that longer paper can be better accepted, and the whole stack of paper is prevented from collapsing.
