Description
Technical Field
[0001] This utility model relates to the field of printer technology, and in particular to a paper flyer assembly and a label printer. Background Technology
[0002] A printer is an office device that is typically used to laminate or coat the surface of printed documents with a transparent film to increase their durability, appearance, and protection. This type of printer is commonly used to produce various documents such as business cards, quotations, menus, posters, signs, and maps, making them more durable and preventing water, stains, tears, and fading.
[0003] However, in the current market, label printers often handle labels that are too short during the printing, cutting, and paper output process. As a result, the labels tend to get stuck in the paper output tray, making them difficult to remove. Utility Model Content
[0004] This application addresses the shortcomings of existing methods by providing a paper feed assembly and a label printer to solve the technical problem that labels tend to remain in the "paper output tray" and are difficult to retrieve.
[0005] In one aspect, embodiments of this application provide a paper-flying assembly applied to a label printer. The paper-flying assembly mainly includes a support, a rotating shaft, a first elastic element, a paper-flying wheel, a cutter, and a rotating arm. The support moves between a clearance position and a paper-flying position. The rotating shaft is mounted on the support and rotates about its own axis relative to the support in a first circumferential direction or a second circumferential direction. The first circumferential direction and the second circumferential direction are opposite. The first elastic element is mounted on the rotating shaft, and the first elastic element deforms and accumulates elastic potential energy to drive the rotating shaft to rotate in the second circumferential direction during the first circumferential rotation phase. The paper-flying wheel is sleeved outside the rotating shaft. The cutter is located on one side of the support and moves between the cut position and the shearing position. A rotating arm is located on one side of the cutter, and the rotating arm, the cutter, the rotating shaft, and the support are all linked. The rotating arm moves between a first position and a second position. During the stage where the cutter moves towards the shearing position, the rotating arm rotates towards the second position, the support moves towards the paper-flying position, and the rotating shaft rotates along the first circumferential direction. During the stage where the cutter moves towards the cut position, the rotating arm rotates towards the first position, the support moves towards the clearance position, and the rotating shaft and the paper-flying wheel both rotate along the second circumferential direction.
[0006] As an optional implementation, the cutter includes a shearing section and a connecting section connected at an angle; one of the connecting section and the rotating arm has an elongated guide hole, and the other forms a guide post inserted into the guide hole; during the movement of the cutter between the cut position and the shearing position, the guide post moves along the length direction of the guide hole, so that the cutter and the rotating arm rotate in the same direction.
[0007] As an optional implementation, the paper-flying assembly further includes a blade drive and a plurality of gears connected between the blade drive and the cutter; the last gear is connected to the cutter, and the last gear is a cam, one of the cam and the connecting section having a curved limiting hole, and the other forming a limiting post inserted into the limiting hole; during the stage when the cutter moves between the cutting position and the shearing position, the limiting post moves along the bending direction of the limiting hole.
[0008] As an optional implementation, the rotating arm includes a first rotating segment and a second rotating segment connected at an angle; the second rotating segment is connected to the cutter drive; the first rotating segment includes a first sub-segment and a second sub-segment connected to each other, the second sub-segment is connected to the second rotating segment, the second sub-segment is disposed on the first side of the bracket, the first sub-segment is bent, the first sub-segment bends and extends from the first side of the bracket to the back side of the bracket, and then bends and extends to the second side of the rotating shaft, the end of the first sub-segment away from the second sub-segment contacts the side of the rotating shaft; the first side and the second side of the rotating shaft are opposite sides; the back side of the bracket is away from the fly paper position.
[0009] As an optional implementation, the paper-flying assembly further includes a vertical wall and a driven wheel; the vertical wall is disposed on the opposite side of the bracket, the bracket moves towards the paper-flying position along the direction close to the vertical wall, and the bracket moves away from the vertical wall to the clearance position; the vertical wall is recessed in the direction away from the bracket to form a mounting recess; the driven wheel is fixed in the mounting space; when the bracket is in the paper-flying position, the driven wheel and the paper-flying wheel clamp the label between them.
[0010] As an optional implementation, the rotating shaft includes a first shaft and a second shaft connected together. The second shaft is cylindrical, and the first shaft protrudes outward from the second shaft radially. The first elastic element is a torsion spring, and both the first elastic element and the paper roller are sleeved on the outside of the second shaft. One end of the first elastic element is also fixedly connected to the bracket. The first shaft is supported by the paper roller, and the side of the first shaft contacts one end of the rotating arm.
[0011] As an optional implementation, the paper roller includes a one-way bearing and a ring sleeve; the one-way bearing is sleeved on the outside of the rotating shaft; the ring sleeve is sleeved on the outside of the one-way bearing to increase the friction with the label.
[0012] As an optional implementation, the rotating arm and the support are rotatably connected via a rotating shaft; the paper-flying assembly further includes a second elastic element, which is installed on the rotating shaft and is also connected to the support and the rotating arm, so that the rotating arm pulls or pushes the support to move in the same direction.
[0013] As an optional implementation, a third position exists between the first position and the second position; during the phase where the rotating arm moves from the first position to the third position, the cutter moves towards the cutting position, and the rotating arm pulls the support towards the paper-flying position via the second elastic element, while the rotating shaft rotates along the first circumferential direction, and the first elastic element deforms to accumulate elastic potential energy; during the phase where the rotating arm moves from the third position to the second position, the cutter continues to move towards the cutting position, the second elastic element deforms to accumulate elastic potential energy, and the support remains at the paper-flying position; during the phase where the rotating arm moves from the second position to the third position, the cutter moves towards the position to be cut, the second elastic element deforms to release the accumulated elastic potential energy, and the support remains at the paper-flying position; during the phase where the rotating arm moves from the third position to the first position, the cutter continues to move towards the position to be cut, and the rotating arm pushes the support towards the avoidance position via the second elastic element, while the rotating shaft rotates along the second axial direction, and the first elastic element deforms to release the accumulated elastic potential energy.
[0014] Secondly, embodiments of this application provide a label printer, including the paper flyer assembly described in any of the foregoing embodiments.
[0015] This application provides a paper-flying assembly and a label printer. The technical solutions provided by the embodiments of this application bring at least the following beneficial effects:
[0016] During the cutting phase, the blade moves to the cutting position, causing the rotating arm to move to the second position. The rotating arm pushes the rotating shaft to rotate around its own axis along the first circumference. The rotating shaft causes the first elastic element to deform and accumulate elastic potential energy. The rotating arm also drives the support to move to the paper-flying position. During the cutting phase, the blade moves to the cutting position, causing the rotating arm to move to the first position. The rotating arm moves away from the rotating shaft, and the first elastic element deforms and releases the accumulated elastic potential energy, causing the paper-flying wheel to rotate rapidly along the second circumference to eject the label, preventing the label from staying and making it easy to remove.
[0017] The label printer's cutter, rotating arm, support, first elastic element, and second elastic element are strictly synchronized. Paper ejection occurs immediately after the label is cut, at the moment when it is most likely to get stuck, ensuring that the paper ejection action happens after the label is cut and that the cutter's reset is not disturbed. Utilizing the power of the shearing motor, the paper ejection function is achieved through mechanical linkage and energy storage in the elastic elements. Small labels automatically pop out, eliminating the need for users to manually remove them and preventing labels from remaining in the paper tray and obstructing subsequent labels. This greatly reduces the risk of paper jams and is especially suitable for scenarios requiring continuous, rapid printing of small labels, improving printing efficiency. The entire paper ejection assembly has a high degree of integration, without significantly increasing the printer's size.

It should be further understood that the term “comprising” as used in the specification of this application means the presence of the stated features, elements, and / or components, but does not exclude the presence or addition of one or more other features, elements, components, and / or groups thereof.

[0052] like Figure 1-11 As shown, this application provides a paper-flying assembly for use in a label printer. The paper-flying assembly mainly includes a support 1, a rotating shaft 2, a first elastic element 3, a paper-flying wheel 4, a cutter 5, and a rotating arm 6. The support 1 moves between a clearance position and a paper-flying position. The rotating shaft 2 is mounted on the support 1 and rotates about its own axis relative to the support 1 in a first circumferential direction or a second circumferential direction. The first circumferential direction and the second circumferential direction are opposite. The first elastic element 3 is mounted on the rotating shaft 2, and the first elastic element 3 deforms and accumulates elastic potential energy to drive the rotating shaft 2 to rotate in the second circumferential direction during the rotation of the rotating shaft 2 in the first circumferential direction. The paper-flying wheel 4 is mounted on the outside of the rotating shaft 2; the cutter 5 is mounted on one side of the support 1 and moves between the cut position and the shearing position; the rotating arm 6 is mounted on one side of the cutter 5 and is linked with the cutter 5, the rotating shaft 2, and the support 1. The rotating arm 6 moves between the first position and the second position; when the cutter 5 moves to the shearing position, the rotating arm 6 rotates to the second position, the support 1 moves to the paper-flying position, and the rotating shaft 2 rotates along the first circumferential direction; when the cutter 5 moves to the cut position, the rotating arm 6 rotates to the first position, the support 1 moves to the avoidance position, and the rotating shaft 2 and the paper-flying wheel 4 rotate along the second circumferential direction.
[0053] In this embodiment, the bracket 1 includes a rotating connecting section 52 and a mounting section connected at an angle, with the mounting section higher than the rotating connecting section 52. The rotating shaft 2 and the paper-flying wheel 4 are coaxially mounted on the mounting section. The bracket 1 rotates about the bottom of the rotating connecting section 52 as an axis towards either a clearance position or a paper-flying position. When the bracket 1 is in the clearance position, the paper-flying wheel 4 is in contact with the label. When the bracket 1 is in the paper-flying position, the paper-flying wheel 4 is in contact with the label. When the cutter 5 is in the cutting position, it moves away from the label; when the cutter 5 is in the shearing position, it cuts off the label to be ejected.
[0054] The movement of the cutter 5 drives the movement of the rotating arm 6; the movement of the rotating arm 6 drives the movement of the bracket 1; the rotating arm 6 also acts on the rotating shaft 2, causing the rotating shaft 2 to rotate. The rotating shaft 2 rotates in different directions, causing the first elastic element 3 to deform and accumulate elastic potential energy or release the accumulated elastic potential energy. The paper roller 4 uses the elastic potential energy released by the first elastic element 3 to rotate rapidly, and uses friction to eject the label cut by the cutter 5.
[0055] In the paper-flying assembly provided in this application embodiment, during the stage where the cutter 5 moves to the cutting position, it drives the rotating arm 6 to move to the second position. The rotating arm 6 pushes the rotating shaft 2 to rotate around its own axis along the first circumferential direction. The rotating shaft 2 causes the first elastic element 3 to deform and accumulate elastic potential energy. The rotating arm 6 also drives the support 1 to move to the paper-flying position. During the stage where the cutter 5 moves to the position to be cut, it drives the rotating arm 6 to move to the first position. The rotating arm 6 moves away from the rotating shaft 2. The first elastic element 3 deforms and releases the accumulated elastic potential energy, causing the paper-flying wheel 4 to rotate rapidly along the second circumferential direction to pop out the label, avoiding the label from staying and making it easy to remove.
[0056] like Figure 1-4 As shown in Figure 6, as an optional embodiment, the cutter 5 includes a shearing section 51 and a connecting section 52 connected at an angle; one of the connecting section 52 and the rotating arm 6 has an elongated guide hole A, and the other forms a guide post B inserted into the guide hole A; during the movement of the cutter 5 between the cut position and the shearing position, the guide post B moves along the length direction of the guide hole A, so that the cutter 5 and the rotating arm 6 rotate in the same direction.
[0057] Based on the aforementioned embodiments, in this embodiment, the cutter 5 is bent, and the shearing section 51 and the connecting section 52 are connected at an obtuse angle. This disperses the shearing force, prevents premature damage, and extends service life. Both the shearing section 51 and the connecting section 52 have a certain length. The guide hole A is opened along the thickness direction of the connecting section 52 or the rotating arm 6, and the guide hole A also extends along the length direction of the connecting section 52 or the rotating arm 6. The guide post B extends along the thickness direction of the connecting section 52 or the rotating arm 6.
[0058] The cutting section 51 is used to cut the label, and the connecting end is used to connect with the rotating arm 6 and the power source. The cutter 5 is a moving blade, and the paper-flying assembly also includes a fixed blade, which is located on one side of the bracket 1 and opposite to the cutter 5. The cutter 5 moves toward the fixed blade to achieve cutting. When the cutter 5 rotates in one direction, it drives the rotating arm 6 to rotate in the same direction, and the rotating arm 6 drives the bracket 1 to rotate in the same direction.
[0059] like Figure 1-3As shown, in an optional implementation, the paper-flying assembly also includes a blade drive 7 and a plurality of gears 8 connected between the blade drive 7 and the cutter 5; the last gear 8 is connected to the cutter 5, and the last gear 8 is a cam, one of which and the connecting section 52 have a curved limiting hole X, and the other forms a limiting post Y inserted into the limiting hole X; during the stage when the cutter 5 moves between the cut position and the shearing position, the limiting post Y moves along the bending direction of the limiting hole X.
[0060] Based on the aforementioned embodiments, in this embodiment, the blade drive 7 provides power for the movement of the cutter 5 via a motor. The first gear 8 of the plurality of gears 8 is connected to the output shaft of the blade drive 7. Both the limiting hole X and the limiting post Y are formed along the thickness direction of the cam or connecting section 52. The rotating cam drives the cutter 5 to rotate synchronously via the limiting post Y and the limiting hole X.
[0061] like Figure 1-4 As shown in Figure 7, as an optional implementation, the rotating arm 6 includes a first rotating segment 61 and a second rotating segment 62 connected at an angle; the second rotating segment 62 is connected to the cutter 5 in a transmission manner; the first rotating segment 61 includes a first sub-segment 611 and a second sub-segment 612 connected to each other, the second sub-segment 612 is connected to the second rotating segment 62, the second sub-segment 612 is disposed on the first side of the bracket 1, the first sub-segment 611 is bent, the first sub-segment 611 bends and extends from the first side of the bracket 1 to the back side of the bracket 1, and then bends and extends to the second side of the rotating shaft 2, the end of the first sub-segment 611 away from the second sub-segment 612 contacts the side of the rotating shaft 2; the first side and the second side of the rotating shaft 2 are opposite sides; the back side of the bracket 1 is away from the position of the flying paper.
[0062] Based on the aforementioned embodiments, in this embodiment, both the first rotating segment 61 and the second rotating segment 62 have a certain length and are connected at an obtuse angle. The aforementioned guide hole A or guide post B is formed in the second rotating segment 62. The first sub-segment 611 of the first rotating segment 61 is straight, and the second sub-segment 612 is bent, bending from one side of the rotating shaft 2 to the other side to contact the rotating shaft 2. This avoids the need for additional transmission components, making the structure of the flying paper assembly more compact and reducing the space occupied.
[0063] like Figure 1-3 As shown, in an optional implementation, the paper-flying assembly also includes a vertical wall 9 and a driven wheel 100; the vertical wall 9 is disposed on the opposite side of the bracket 1, the bracket 1 moves to the paper-flying position in the direction close to the vertical wall 9, and the bracket 1 moves to the avoidance position in the direction away from the vertical wall 9; the vertical wall 9 is recessed in the direction away from the bracket 1 to form a mounting recess; the driven wheel 100 is fixed in the mounting space; when the bracket 1 is in the paper-flying position, the driven wheel 100 and the paper-flying wheel 4 clamp the label between them.
[0064] Based on the aforementioned embodiments, in this embodiment, the vertical wall 9 serves as part of the paper output tray. The bottom of the vertical wall 9 has a guide groove, along which the label moves closer to or further away from the driven wheel 100. The driven wheel 100 is vertically oriented axially, with a portion of it protruding from the vertical wall 9. The label moves along the arc surface of the driven wheel 100, reducing friction and preventing scratching during label transport. When the support 1 is in the flyer position, the driven wheel 100 and the flyer wheel 4 are close together and clamp the label; the flyer wheel 4 rotates to eject the label, and the driven wheel 100 rotates with the label, again preventing scratching during label transport. When the support 1 moves to the avoidance position, the driven wheel 100 and the flyer wheel 4 move away from each other, avoiding obstruction of label movement.
[0065] like Figure 1-4 As shown in Figure 8, as an optional implementation, the rotating shaft 2 includes a first shaft 21 and a second shaft 22 connected to each other. The second shaft 22 is cylindrical, and the first shaft 21 protrudes outward from the second shaft 22 along the radial direction of the second shaft 22. The first elastic element 3 is a torsion spring. The first elastic element 3 and the paper roller 4 are both sleeved on the outside of the second shaft 22. One end of the first elastic element 3 is also fixedly connected to the bracket 1. The first shaft 21 is supported on the paper roller 4, and the side of the first shaft 21 is in contact with one end of the rotating arm 6.
[0066] Based on the aforementioned embodiments, in this embodiment, the first shaft 21 is block-shaped and supported by the second shaft 22. The end of the first rotating segment 61 of the rotating arm 6 away from the second rotating segment 62 contacts the first shaft 21; when the rotating arm 6 moves to the second position, the rotating arm 6 pushes the rotating shaft 2 to rotate along the first circumferential direction, causing the first elastic element 3 to accumulate elastic potential energy; when the rotating arm 6 moves to the first position, the rotating arm 6 is still in contact with the first shaft 21, but the constraint of the first shaft 21 disappears, and the rotating shaft 2 rotates along the second circumferential direction under the action of the torsion spring. When under appropriate conditions, the first elastic element 3 automatically releases the stored energy to drive the flying paper wheel 4 to rotate and drive the label to "fly out".
[0067] like Figure 1-4 As shown, in one optional implementation, the paper roller 4 includes a one-way bearing 41 and a ring 42; the one-way bearing 41 is sleeved on the outside of the rotating shaft 2; the ring 42 is sleeved on the outside of the one-way bearing 41 to increase the friction with the label.
[0068] By employing the above scheme, the rotation shaft 2 is restricted to rotating only in the direction of the flying paper, ensuring that it can only rotate in the direction of energy storage, preventing premature energy release, and improving the efficiency of the flying paper ejection. Friction is increased by the ring 42 to prevent the flying paper wheel 4 from slipping and failing to eject the label.
[0069] In some embodiments, the material of the ring 42 includes silicone.
[0070] To increase friction, the structure of the ring 42 can be improved; for example, the outer surface of the ring 42 can be formed with a micro-serrated structure. However, this must not damage the label or cause the label to stick.
[0071] like Figure 1-3 As shown, in one optional implementation, the rotating arm 6 is rotatably connected to the support 1 via a rotating shaft; the paper-flying assembly also includes a second elastic element 200, which is installed on the rotating shaft and is also connected to the support 1 and the rotating arm 6, so that the rotating arm 6 pulls or pushes the support 1 to move in the same direction.
[0072] Based on the aforementioned embodiments, in this embodiment, the rotating connecting section 52 at the bottom of the bracket 1 is rotatably connected to the rotating arm 6 via a rotating shaft. The second elastic element 200 is a torsion spring, which is sleeved on the outside of the rotating shaft. One end of the second elastic element 200 is engaged with the rotating arm 6, and the other end of the second elastic element 200 is engaged with the rotating connecting section 52.
[0073] like Figure 9-11 As shown, in one optional implementation, a third position exists between the first and second positions; during the phase where the rotating arm 6 moves from the first position to the third position, the cutter 5 moves towards the cutting position, and the rotating arm 6 pulls the support 1 towards the paper-flying position via the second elastic element 200, while the rotating shaft 2 rotates along the first circumferential direction, and the first elastic element 3 deforms to accumulate elastic potential energy; during the phase where the rotating arm 6 moves from the third position to the second position, the cutter 5 continues to move towards the cutting position, the second elastic element 200 deforms to accumulate elastic potential energy, and the support 1 remains at the paper-flying position; during the phase where the rotating arm 6 moves from the second position to the third position, the cutter 5 moves towards the position to be cut, the second elastic element 200 deforms to release the accumulated elastic potential energy, and the support 1 remains at the paper-flying position; during the phase where the rotating arm 6 moves from the third position to the first position, the cutter 5 continues to move towards the position to be cut, and the rotating arm 6 pushes the support 1 towards the avoidance position via the second elastic element 200, while the rotating shaft 2 rotates along the second axis 22, and the first elastic element 3 deforms to release the accumulated elastic potential energy.
[0074] Based on the aforementioned embodiments, in this embodiment, the third position is located between the first and second positions in the path of the rotating arm 6.
[0075] During the stage where the cutter 5 moves from the position to the cutting position, it drives the rotating arm 6 to move from the first position to the third position. The rotating arm 6 drives the rotating shaft 2 to rotate along the first circumference, causing the first elastic element 3 to deform and accumulate elastic potential energy. The rotating arm 6 pulls the bracket 1 from the avoidance position to the paper-flying position through the second elastic element 200. When the rotating arm 6 is in the third position, the paper-flying wheel 4 is pressed and connected with the label, and the first elastic element 3 accumulates the maximum elastic potential energy.
[0076] During the movement of the rotating arm 6 from the third position to the second position, the paper roller 4 is connected to the label by compression to keep the support 1 stationary. The rotating arm 6 continues to move to the second position, and the second elastic element 200 deforms to accumulate elastic potential energy. When the rotating arm 6 is in the second position, the second elastic element 200 accumulates the maximum elastic potential energy.
[0077] During the stage when the cutter 5 moves from the cutting position to the position to be cut, the rotating arm 6 moves from the second position to the third position. During this stage, the first elastic element 3, the rotating shaft 2, and the paper roller 4 are relatively stationary. The second elastic element 200 releases its elastic potential energy to maintain the pressure of the paper roller 4 on the label.
[0078] During the movement of the rotating arm 6 from the third position to the first position, the rotating shaft 2 rotates along the second circumference, the first elastic element 3 releases elastic potential energy, and the paper-flying wheel 4 rotates rapidly to eject the label. The rotating arm 6 pushes the support 1 from the paper-flying position to the avoidance position through the second elastic element 200.
[0079] like Figure 12-14 As shown, based on the same inventive concept, this application provides a label printer, including the paper-flying component of any of the foregoing embodiments.
[0080] The label printer's cutter 5, rotating arm 6, bracket 1, first elastic element 3, and second elastic element 200 are strictly synchronized. Paper ejection occurs immediately after the label is cut, at the moment when it is most likely to get stuck, ensuring that the paper ejection action happens after the label is cut and that the cutter 5's reset is not disturbed. Utilizing the power of the shearing motor, the paper ejection function is achieved through mechanical linkage and energy storage in the elastic elements. The label automatically pops out, eliminating the need for the user to manually remove it, preventing labels from remaining in the paper tray and obstructing subsequent labels, greatly reducing the risk of paper jams. This is especially suitable for scenarios requiring continuous, rapid printing of small labels, improving printing efficiency. The entire paper ejection assembly has a high degree of integration, without significantly increasing the size of the label printer.
