[0052] See also Figure 3As shown, the manual sticker dispenser 100 includes a housing 1, the housing 1 having a second cavity 110 for accommodating a sticker roll 8, a conveying path 112 defined in the second cavity 110, and an output port 101 communicating with the second cavity 110. A peeling structure 1121 is arranged on the conveying path 112, the peeling structure 1121 is located at the output port 101, and the peeling structure 1121 can peel the sticker from the backing paper 81 by conveying the backing paper 81 in a direction different from the traveling direction of the sticker. Specifically, the peeling structure 1121 includes a deflection peeling portion, the backing paper 81 extends toward the output port 101 in a relatively flat posture at the upstream of the deflection peeling portion, and the backing paper 81 is reversely bent at the deflection peeling portion so that the traveling direction of the backing paper 81 is different from the traveling direction of the sticker, so that the sticker is peeled from the backing paper 81. The backing paper 81 that is reversely bent at the turning and peeling portion is wound on the winding shaft 111. When the winding shaft 111 is driven to rotate, the backing paper 81 and the sticker pasted thereon are pulled to move on the conveying path 112, and the sticker is peeled off through the peeling structure 1121.

[0053] See also Figure 3 and Figure 4 As shown, the manual sticker dispenser 100 includes a winding shaft 111, a transmission mechanism and an operating member 2. The operating member 2 is connected to the transmission mechanism, and the transmission mechanism is connected to the winding shaft 111 in a power transmission manner. The operating member 2 is configured to be able to reciprocate operably within a set range; specifically, the operating member 2 is configured to be able to move along a first direction driven by an operating force to move from a first position to a second position, and to be able to move along a second direction opposite to the first direction when the operating force is released to reset from the second position to the first position. In the process of the operating member 2 moving from the first position to the second position, a continuous power transmission chain is formed between the operating member 2, the transmission mechanism and the winding shaft 111 to drive the winding shaft 111 to rotate forward to wind the backing paper 81; in the process of the operating member resetting from the second position to the first position, the power transmission at least one point between the operating member 2, the transmission mechanism and the winding shaft 111 is disconnected to avoid driving the winding shaft 111 to reverse.

[0054] Please continue reading Figure 3 and Figure 4As shown, in this embodiment, the housing 1 includes a main body shell 11, an upper cover 12 covering the top of the main body shell 11, and a lower cover 13 covering the bottom of the main body shell 11. The main body shell 11 has a bottom wall and a peripheral wall arranged at the edge of the bottom wall, and the upper and lower edges of the peripheral wall extend beyond the bottom wall to enclose a second cavity 110 above the bottom wall to accommodate the sticker roll 8 and the winding shaft 111, and to enclose a first cavity 115 below the bottom wall to install the operating member 2 and the transmission mechanism. An elastic buckle 121 is provided at one end of the upper cover 12 for detachably connecting the upper cover 12 to the main body shell 11, so as to facilitate the replacement of the sticker roll 8; the lower cover 13 is fixed to the main body shell 11 by screws to prevent the user from easily opening the lower cover 13 and causing the transmission mechanism installed in the first cavity 115 to scatter.

[0055] See also Figures 4 to 6 As shown, in this embodiment, the operating member 2 is a pressable component, specifically a lever mechanism, which is configured to swing around a set axis. The operating member 2 is pivotally connected to the housing 1, and includes a pressing portion 21 and a rack portion 22. The pressing portion 21 is exposed to the housing 1 and can be pressed by the user. The operating member 2 is in a first position before being pressed, and can move to a second position after being subjected to a pressing force. When the pressing portion 21 is subjected to a pressing force, the operating member 2 rotates around its pivot axis, driving the rack portion 22 to move. The operating member 2 is an integral part, for example, it can be plastic injection molding, and a plurality of teeth are integrally molded on the rack portion 22 for cooperating with a transmission mechanism to transmit power. In this embodiment, the rack portion 22 is arc-shaped, and the axis center of the arc is the axis center of the pivot axis of the operating member 2. One end of the operating member 2 close to the rack portion 22 is elastically pressed against by a return spring 23. The elastic force provided by the return spring 23 is opposite to the direction of the pressing force. When the pressing force applied to the pressing portion 21 is removed, the return spring 23 pushes the operating member 2 to rotate and return to the first position before the pressing force is applied.

[0056] Please continue reading Figures 4 to 6As shown, the transmission mechanism is a gear train transmission mechanism composed of a plurality of gears coupled to each other, which is configured to transmit the operating member 2 and the winding shaft 111, and can transmit the power output by the operating member 2 to the winding shaft 111 to drive the winding shaft 111 to rotate; the transmission mechanism includes a one-way clutch device, which is configured to be coupled to implement the power transmission when the operating member 2 moves in a first direction, and to be separated to disconnect the power transmission when the operating member 2 moves in a second direction opposite to the first direction. In this embodiment, the transmission mechanism includes a driven gear 5 relatively fixed to the winding shaft 111, an actuating gear 3 meshing with the rack portion 22 of the operating member 2, and a movable gear 4 arranged between the driven gear 5 and the actuating gear 3. Specifically, the transmission mechanism includes an actuating gear 3 located upstream of the movable gear 4 in the transmission direction of the power and coupled thereto; and a driven gear 5 located downstream of the movable gear 4 in the transmission direction and detachably coupled thereto.

[0057] The gear shaft of the actuating gear 3 is connected to the housing 1 in a non-translationally movable manner. The actuating gear 3 can only rotate around the axis of its gear shaft, but cannot move in the axial and radial directions. In this embodiment, the actuating gear 3 is a double-layered tower gear having a coaxial small-diameter toothed disc 31 and a large-diameter toothed disc 32. The small-diameter toothed disc 31 of the actuating gear 3 is meshed with the rack portion 22 of the operating member 2, and the large-diameter toothed disc 32 of the actuating gear 3 is meshed with the movable gear 4. In another embodiment, only the large-diameter rack 32 can be understood as the actuating gear, and the small-diameter toothed disc 31 can be understood as the first gear coupled to the rack portion 22 further included in the transmission mechanism, the first gear and the actuating gear are coaxially arranged, and the diameter D of the actuating gear is more than one times the diameter d of the first gear.

[0058] The movable gear 4 is configured to be movable between a coupling position and a separation position, that is, the gear shaft of the movable gear 4 is translationally connected to the housing 1, and the movable gear 4 can also rotate around the axis of its gear shaft. One end of the gear shaft of the movable gear 4 is connected to the bottom wall of the main shell 11, and the other end is connected to the lower cover 13; specifically, an upper elongated groove 113 is provided on the bottom wall of the main shell 11, for the upper end of the gear shaft of the movable gear 4 to be inserted and slide therein; a lower elongated groove 131 is provided on the lower cover 13, for the lower end of the gear shaft of the movable gear 4 to be inserted and slide therein. The upper elongated groove 113 and the lower elongated groove 131 are opposite to each other up and down, forming a guide groove for the rotating shaft of the movable gear 4 to be inserted and slide therein. When the rack portion 22 of the operating member 2 meshes with the movable gear 4, the movable gear 4 can be pushed to slide along the guide groove, and can be meshed and connected with the driven gear 5 when sliding to the coupling position, and can be disengaged from the driven gear 5 when sliding to the separation position.

[0059] In this embodiment, the one-way clutch device includes the movable gear 4 and a force member 6. The movable gear 4 is elastically pushed by the force member 6, and the force member 6 is configured to apply an elastic force to the movable gear 4 to keep it in the coupling position, and when the operating member 2 moves from the second position to the first position along the second direction, it drives the movable gear 4 to overcome the elastic force and slide to the separation position. The force member 6 is a torsion spring or a spring sheet, which has an elastic arm that abuts against the movable gear 4 to apply an elastic force. In this embodiment, the force member 6 is a torsion spring, which has two elastic arms, one of which abuts against the movable gear 4 and the other abuts against the housing 1. In this embodiment, the spring force of the force member 6 is overcome to separate the movable gear 4 from the driven gear 5. In another embodiment, the force member 6 is configured to apply an elastic force to the movable gear 4 to keep it in the separated position, and when the operating member 2 moves from the first position to the second position along the first direction, the movable gear 4 is driven to overcome the elastic force and slide to the coupling position; this embodiment is to release the movable gear 4 to separate under the action of the spring force of the force member 6. For this embodiment, when the external force on the operating member 2 is removed, the force member 6 immediately drives the movable gear 4 to separate from the driven gear 5, and the separation is more timely, which can better avoid driving the driven gear 5 to reverse. For this embodiment, when the operating member 2 moves along the first direction, there is a short sliding distance for the movable gear 4 to move from the separated position to the coupled position, and in this distance, the driven gear 5 is not driven, that is, there is a short idle stroke of the operating member 2. In the above-mentioned embodiment, the elastic reset force provided by the reset spring 23 is greater than the elastic force applied by the force member 6 to the movable gear 4.

[0060] In this embodiment, the movable gear 4 is a double-layered pyramidal gear having a coaxial small-diameter toothed disc 41 and a large-diameter toothed disc 42, wherein the small-diameter toothed disc 41 of the movable gear 4 is meshed with the driven gear 5, and the large-diameter toothed disc 42 of the movable gear 4 is meshed with the large-diameter rack 32 of the actuating gear 3. The arrangement of the actuating gear 3 and the movable gear 4 can play an amplifying role, and the rotation angle of the actuating gear 3 is smaller than the rotation angle of the driven gear 5 during the movement of the operating member 2 from the first position to the second position.

[0061] The driven gear 5 is coaxially and relatively fixedly connected to the winding shaft 111. In this embodiment, the driven gear 5 is connected to the winding shaft 111 through a coupling structure. Specifically, a polygonal cylinder is provided on the gear shaft of the driven gear 5, and a polygonal sleeve is provided at the lower end of the winding shaft 111. The polygonal cylinder is inserted into the polygonal sleeve to achieve relative fixation of the two in the rotation direction.

[0062] Please refer to Figure 7 As shown in FIG. 1 , it is a schematic diagram of the action of the transmission mechanism during the process in which the operating member 2 is driven by the operating force to move along the first direction: at this time, the pressing portion 21 of the operating member 2 is applied with a force as indicated by the arrow thereon, the rack portion 22 of the operating member 2 rotates inward as indicated by the arrow thereon, and the actuating gear 3 rotates clockwise as shown in the figure, at this time, the movable gear 4 is pushed to translate toward the direction close to the driven gear 5 and meshes with the driven gear 5, and the driven gear 5 rotates clockwise as shown in the figure, driving the winding shaft 111 to rotate, so as to pull the backing paper 81 to move, thereby realizing the peeling and output of the sticker.

[0063] Please refer to Figure 8 As shown in the figure, it is a schematic diagram of the action of the transmission mechanism in the process in which the operating force applied to the operating member 2 is released and the operating member 2 is driven by the reset spring 23 to move in the second direction to reset to the first position: at this time, the rack portion 22 of the operating member 2 is applied with a force as shown by the arrow thereon, the pressing portion 21 of the operating member 2 moves outward as shown by the arrow thereon, and the actuating gear 3 rotates counterclockwise as shown in the figure, at this time the movable gear 4 is pushed to translate in a direction away from the driven gear 5 and disengages from the meshing with the driven gear 5, at this time the actuating gear 3 drives the rotation of the movable gear 4, which cannot be transmitted to the driven gear 5, that is, the driven gear 5 will not rotate in the reverse direction, and the winding shaft 111 will not move, thereby avoiding that during the resetting process of the operating member 2, the winding shaft 111 rotates in the reverse direction, causing the wound backing paper to loosen, and causing the sticker to fail to be output when pressed next time.

[0064] It should be noted that this embodiment is described by taking the example that the movable gear 4 and the driven gear 5 can be disengaged. It can be understood that in other embodiments, it is sufficient as long as any position in the transmission chain between the operating member 2 and the winding shaft 111 is set to be disengaged. It should also be noted that this embodiment realizes the switching between engagement and disengagement by the translation of the movable gear 4. In other embodiments, it can also be realized by a ratchet structure; for example, in some embodiments, the one-way clutch device is a one-way bearing, that is, an overrunning clutch, and the one-way bearing is engaged with a transmission gear in the transmission mechanism; the one-way bearing can be disengaged from the winding shaft 111 in one direction and rotate freely, and is locked with the winding shaft 111 in the other direction opposite thereto, and the two rotate synchronously.

[0065] Through the above description of the specific embodiment, it can be known that the manual sticker dispenser 100 provided by the utility model includes a winding shaft 111, a transmission mechanism and an operating member 2, wherein the operating member 2 is configured to be able to move in a first direction driven by an operating force, and to be able to move in a second direction opposite to the first direction when the operating force is released. During the movement of the operating member 2 in the first direction, a continuous power transmission chain is formed between the operating member 2, the transmission mechanism and the winding shaft 111 to drive the winding shaft 111 to rotate and wind the backing paper. During the movement of the operating member 2 in the second direction, the one-way clutch device disconnects the power transmission to avoid driving the winding shaft 111 to reverse. Therefore, the output of stickers can be achieved by manually applying force to the operating member 2, without the need to use electrical components, which can reduce costs and enhance operability and entertainment.

The foregoing detailed description is intended to be considered illustrative rather than restrictive, and it should be understood that the appended claims, including all equivalents, are intended to define the scope of the utility model.
