[0002] The paper pick-up bracket is generally provided with a flange structure to block the original document baffle, so that the position of the original document baffle remains stable, so that the original document can be aligned when it is inserted.
[0003] At present, the contact surface between the flange structure and the original document baffle is designed to be vertical, and the rotating shaft of the paper pick-up bracket is usually on the lower side of the force point. As a result, when the original document baffle is subjected to excessive force, the paper pick-up bracket will be subjected to a downward component force accordingly. Under the action of this component force, the paper pick-up bracket will rotate downward, thereby losing the function of blocking the original document baffle, resulting in deviation of the original placement position front and back and inability to align. Utility Model Content
[0004] The utility model aims to provide a paper alignment mechanism and a printer to solve the technical problem in the related art that the paper pick-up bracket fails to block the original document blocking piece.

[0008] The paper picking bracket is hinged to the upper cover via a rotating shaft, and the side surface of the paper picking bracket located in the axial direction of the rotating shaft is protruded to form a flange;
[0009] The surface of the flange used for contacting the original document blocking sheet is an inclined surface, and the inclined surface is inclined from the top end to the bottom end of the flange in a direction away from the rotating shaft.
[0010] Furthermore, the document blocking piece includes a limiting shaft, which extends along the axial direction of the rotating shaft and is used to interfere with the inclined surface.
[0011] Furthermore, the upper cover is provided with a rib plate, and the rib plate is provided with an arc groove;
[0012] The limiting shaft is arranged in the arc groove and can slide along the extending direction of the arc groove when the original document blocking piece rotates.
[0013] Further, the arc-shaped groove has a first end and a second end in opposite directions;
[0014] The limiting shaft can slide from the first end to the second end after the original document blocking piece is separated from the flange.
[0015] Furthermore, the document blocking piece further comprises a rotating shaft, the rotating shaft is rotatably matched with the upper cover, and its extending direction is consistent with the axial direction of the rotating shaft.
[0016] Furthermore, the upper cover is provided with ribs, and the rotating shaft passes through the ribs so as to be rotatable around its own axis.
[0017] Furthermore, two rotating axes are provided, and the two rotating axes are symmetrically distributed.
[0018] Furthermore, the upper cover is provided with a plurality of ribs, and the plurality of ribs are distributed in parallel;

[0020] Furthermore, two original document blocking pieces are provided, and the two original document blocking pieces are symmetrically distributed on both sides of the paper picking bracket.
[0021] In summary, the technical effects that can be achieved by the paper alignment mechanism provided by the utility model are:
[0022] The paper alignment mechanism provided by the utility model comprises an upper cover, an original document baffle and a paper pick-up bracket; the original document baffle is hinged to the upper cover; the paper pick-up bracket is hinged to the upper cover through a rotating shaft, and the side surface of the paper pick-up bracket on the axial direction of the rotating shaft protrudes to form a flange; the surface of the flange used for contacting with the original document baffle is an inclined surface, and the inclined surface is inclined from the top end to the bottom end of the flange in a direction away from the rotating shaft.
[0023] In the paper alignment mechanism, when the original document baffle is subjected to the force from the paper, the original document baffle will rotate around the hinge axis between it and the upper cover until it contacts the flange. Since the surface of the flange that contacts the original document baffle is an inclined surface, and the inclined surface is inclined from the top end to the bottom end of the flange in the direction away from the rotating axis, the direction of the force applied to the flange will be inclined upward relative to the rotating axis, and the force can be divided into an upward component force. Under the action of the upward component force, the paper pick-up bracket has a tendency to rotate upward to contact the upper cover and thus remain in place. In this way, the original document baffle continues to contact the flange and remains in place stably.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0040] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0041] At present, the contact surface between the flange structure and the original document baffle is designed to be vertical, and the rotating shaft of the paper pick-up bracket is usually on the lower side of the force point. As a result, when the original document baffle is subjected to excessive force, the paper pick-up bracket will be subjected to a downward component force accordingly. Under the action of this component force, the paper pick-up bracket will rotate downward, thereby losing the function of blocking the original document baffle, resulting in deviation of the original placement position front and back and inability to align.
[0042] In view of this, the utility model provides a paper alignment mechanism, referring to Figures 1 to 7 , including an upper cover 1, an original document baffle 2 and a paper pick-up bracket 3; the original document baffle 2 is hinged to the upper cover 1; the paper pick-up bracket 3 is hinged to the upper cover 1 through a rotating shaft 4, and the side surface of the paper pick-up bracket 3 in the axial direction of the rotating shaft 4 protrudes to form a flange 301; the surface of the flange 301 used to contact the original document baffle 2 is an inclined surface, and the inclined surface is inclined from the top end to the bottom end of the flange 301 in the direction away from the rotating shaft 4.
[0043] In the paper alignment mechanism, when the document baffle 2 is subjected to a force from the paper, the document baffle 2 will rotate around the hinge axis between the document baffle 2 and the upper cover 1 until it contacts the flange 301. Figure 8 As shown, since the surface of the flange 301 that contacts the document stopper 2 is an inclined surface, and the inclined surface is inclined from the top end to the bottom end of the flange 301 in the direction away from the rotating shaft 4, the direction of the force F applied to the flange 301 will be obliquely upward relative to the rotating shaft 4, and the force can be divided into force components F1 and F2, with the force component F1 being upward; under the action of the upward force component F1, the paper pick-up bracket 3 has a tendency to rotate upward to contact the upper cover 1, thereby remaining in place, and thus, the document stopper 2 continues to contact the flange 301 and remains in place stably.
[0044] It can be seen that compared with the prior art, the paper alignment mechanism designs the surface where the flange 301 contacts the original baffle 2 as an inclined surface, so that when the paper pick-up bracket 3 is subjected to the pressure of the original baffle 2, it will generate an upward component force to support the upper cover 1, thereby stably remaining in place. In this way, the original baffle 2 will also be stably maintained in place, thereby ensuring the stability of the paper placement position.
[0045] It should be added here that the reference Figure 8 , preferably, the angle of the bevel is 10°.
[0046] The following combination Figures 1 to 8 The structure and shape of the paper alignment mechanism provided in this embodiment are described in detail:
[0047] For further reference, Figures 1 to 4 There are two original document baffles 2, which are symmetrically distributed on both sides of the paper pick-up bracket 3; the original document baffle 2 includes a limit shaft 201, which extends along the axial direction of the rotating shaft 4 and is used to abut against the inclined surface.
[0048] Specifically, Figure 3 and Figure 4 For example, a rib 101 is provided on the upper cover 1, and an arc groove 102 is provided on the rib 101, and the arc groove 102 has a first end and a second end in opposite directions; the limit shaft 201 is passed through the arc groove 102, and can slide along the extension direction of the arc groove 102 when the original document blocking piece 2 rotates, and when the limit shaft 201 contacts the flange 301, the limit shaft 201 is at the first end, and when the limit shaft 201 is separated from the flange 301, the limit shaft 201 can slide from the first end to the second end.
[0049] In the above design, the arc groove 102 guides the rotation of the document baffle 2, and cooperates with the flange 301 to limit the rotation of the document baffle 2 in the initial state, so that the paper will not be blocked by the document baffle 2 before being placed in place, ensuring smooth paper placement.
[0050] For further reference, Figures 3 to 7 The document blocking piece 2 further includes a rotating shaft 202 , which is rotatably matched with the upper cover 1 , and its extending direction is consistent with the axial direction of the rotating shaft 4 .
[0051] Specifically, Figure 3 For example, two rotating shafts 202 are provided, and the two rotating shafts 202 are symmetrically distributed and respectively penetrate two adjacent ribs 101. Such a design ensures the stability of the original document blocking sheet 2 during rotation.
[0052] The utility model further provides a printer, which includes a paper alignment mechanism. The technical advantages and effects achieved by the printer also include the technical advantages and effects achieved by the above-mentioned paper alignment mechanism, which will not be described in detail here.
[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
