Abstract
Description
Technical Field
[0001] This utility model relates to the field of sticker dispensing technology, and in particular to a sticker roll carrier for a sticker dispensing machine. Background Technology
[0002] A sticker is a sheet-like object that can be attached to other items. Stickers can be printed with barcodes, QR codes, or various symbols or patterns for recording information, marking, or entertainment. Commonly available stickers are peeled off from a backing paper, requiring the user to manually bend the backing paper to create a small opening between the sticker's edge and the backing paper, then tear the sticker off. This traditional method of peeling off stickers is inconvenient, wrinkles the backing paper, and often results in the sticker or backing paper tearing.
[0003] To facilitate sticker distribution, existing technologies offer various methods for peeling stickers off the backing paper. These include manually pressing a rack and pinion to drive a friction wheel, which uses friction to move the strip and distribute the sticker; or using a motor-driven feed roller, whose friction moves the strip to print and distribute the label.
[0004] However, in these existing technologies, changing the sticker roll requires the user to remove the starting end of the sticker roll and install it into the corresponding channel, which is inconvenient, especially for children. Utility Model Content

[0066] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.
[0067] Please see Figures 1 to 8 A manual sticker dispenser A is used to peel stickers from a sticker roll 71. The stickers are peelably adhered to a backing paper 72 and wound into the sticker roll 71. The manual sticker dispenser A is configured to peel the stickers from the backing paper 72 during sticker delivery and output them from a sticker output port 110.
[0068] Please see Figures 1 to 3 The manual sticker dispenser A includes a housing 1 with a first cavity 14 for accommodating a sticker roll 71. A conveying path 141 is defined within the first cavity 14, and an output port 110 communicating with the first cavity 14 is provided on the housing 1. A peeling structure 142 is disposed on the conveying path 141 at the output port 110. The peeling structure 142 peels the sticker off the backing paper 72 by conveying the backing paper 72 in a direction different from the sticker's direction of travel. Specifically, the peeling structure 142 includes a deflecting peeling section. Upstream of the deflecting peeling section, the backing paper 72 extends towards the output port 110 in a relatively flat manner. At the deflecting peeling section, the backing paper 72 bends in the opposite direction, so that the direction of travel of the backing paper 72 is different from the direction of travel of the sticker, thereby peeling the sticker off the backing paper 72. The backing paper 72, after being bent in the opposite direction at the turning and peeling section, is wound on the winding shaft 140. When the winding shaft 140 is driven to rotate, it pulls the backing paper 72 and the sticker pasted thereon along the transport path 141 and peels off the sticker through the peeling structure 142.
[0069] Please see Figure 3 and Figure 4The manual sticker dispenser A includes a winding shaft 140, a transmission mechanism, and an operating member 41. The operating member 41 is connected to the transmission mechanism, which is power-transmittably connected to the winding shaft 140. The operating member 41 is configured to reciprocate operablely within a set range; specifically, the operating member 41 is configured to move along a first direction driven by an operating force to move from a first position to a second position, and to move along a second direction opposite to the first direction when the operating force is released to return from the second position to the first position. During the movement of the operating member 41 from the first position to the second position, a continuous power transmission chain is formed between the operating member 41, the transmission mechanism, and the winding shaft 140 to drive the winding shaft 140 to rotate forward to wind the backing paper 72; during the return of the operating member 41 from the second position to the first position, the power transmission between the operating member 41, the transmission mechanism, and the winding shaft 140 is disconnected at at least one point to prevent the winding shaft 140 from reversing.
[0070] Please continue reading. Figure 3 and Figure 4 In some embodiments, the housing 1 includes a main housing 11, an upper cover 12 covering the top of the main housing 11, and a lower cover 13 covering the bottom of the main housing 11. The main housing 11 has a bottom wall and a peripheral wall disposed at the edge of the bottom wall. The upper and lower edges of the peripheral wall extend beyond the bottom wall to form a first cavity 14 above the bottom wall to accommodate the sticker roll 71 and the winding shaft 140, and a second cavity 15 below the bottom wall to install the operating member 41 and the transmission mechanism. One end of the upper cover 12 is provided with an elastic buckle 121 for detachably connecting the upper cover 12 to the main housing 11, facilitating the replacement of the sticker roll 71. The lower cover 13 is locked to the main housing 11 with screws to prevent the user from easily opening the lower cover 13 and causing the transmission mechanism installed in the second cavity 15 to fall out.
[0071] Please see Figures 4 to 6In some embodiments, the operating member 41 is a pressable component, specifically a lever mechanism configured to swing about a predetermined axis. The operating member 41 is pivotally connected to the housing 1 and includes a pressing portion 411 and a rack portion 412. The pressing portion 411 protrudes from the housing 1 and can be pressed by the user. Before being pressed, the operating member 41 is in a first position and can move to a second position after being pressed. When the pressing portion 411 is pressed, the operating member 41 rotates about its pivot axis, causing the rack portion 412 to move. The operating member 41 is a single piece, for example, injection molded from plastic. The rack portion 412 has several teeth integrally formed for cooperating with the transmission mechanism to transmit power. In this embodiment, the rack portion 412 is arc-shaped, and the axis of the arc is the axis of the pivot axis of the operating member 41. One end of the operating member 41 near the rack portion 412 is elastically abutted by the return spring 413. The elastic force provided by the return spring 413 is opposite to the direction of the pressing force. When the pressing force applied to the pressing portion 411 is removed, the return spring 413 pushes the operating member 41 to rotate and return to the first position before the pressing force was applied.
[0072] Please continue reading. Figures 3 to 6 The transmission mechanism is a gear train consisting of multiple coupled gears, configured to drive the operating member 41 and the winding shaft 140, and capable of transmitting the power output from the operating member 41 to the winding shaft 140 to drive the winding shaft 140 to rotate. The transmission mechanism includes a one-way clutch device configured to couple to transmit the power when the operating member 41 moves in a first direction, and to disengage to disconnect the power transmission when the operating member 41 moves in a second direction opposite to the first direction. In some embodiments, the transmission mechanism includes a driven gear 44 fixed relative to the winding shaft 140, an actuating gear 42 meshing with the rack portion 412 of the operating member 41, and a movable gear 43 disposed between the driven gear 44 and the actuating gear 42. Specifically, the transmission mechanism includes an actuating gear 42 located upstream of and coupled to the movable gear 43 in the power transmission direction; and a driven gear 44 located downstream of and detachably coupled to the movable gear 43 in the transmission direction.
[0073] The gear shaft of the actuating gear 42 is non-translatably connected to the housing 1. The actuating gear 42 can only rotate about the axis of its gear shaft and cannot move axially or radially. In this embodiment, the actuating gear 42 is a double-layered tower gear with a coaxial small-diameter gear disk 421 and a large-diameter gear disk 422. The small-diameter gear disk 421 of the actuating gear 42 meshes with the rack portion 412 of the operating member 41, and the large-diameter gear disk 422 of the actuating gear 42 meshes with the movable gear 43. In another embodiment, the large-diameter gear disk 422 can also be understood as the actuating gear, and the small-diameter gear disk 421 can be understood as a first gear coupled to the rack portion 412 further included in the transmission mechanism. The first gear and the actuating gear are coaxially arranged, wherein the diameter of the actuating gear is more than twice the diameter of the first gear.
[0074] The movable gear 43 is configured to move between a coupled position and a disengaged position, meaning that the gear shaft of the movable gear 43 is translatably connected to the housing 1, and the movable gear 43 can also rotate about the axis of its gear shaft. One end of the gear shaft of the movable gear 43 is connected to the bottom wall of the main housing 11, and the other end is connected to the lower cover 13. Specifically, the bottom wall of the main housing 11 is provided with an upper elongated groove (not shown) for the upper end of the gear shaft of the movable gear 43 to be inserted and slide within it; the lower cover 13 is provided with a lower elongated groove 131 for the lower end of the gear shaft of the movable gear 43 to be inserted and slide within it. The upper and lower elongated grooves 131 are opposite each other, forming a guide groove for the rotating shaft of the movable gear 43 to be inserted and slide within it. When the rack portion 412 of the operating member 41 meshes with the movable gear 43, it can push the movable gear 43 to slide along the guide groove. When it slides to the coupling position, it can mesh with the driven gear 44. When it slides to the separation position, it disengages from the driven gear 44.
[0075] In some embodiments, the one-way clutch device includes a movable gear 43 and a force-applying member 45. The movable gear 43 is elastically pushed by the force-applying member 45, which is configured to apply an elastic force to the movable gear 43 to maintain it in the coupled position. When the operating member 41 moves along a second direction from a second position to a first position, it drives the movable gear 43 to slide against the elastic force to the disengaged position. The force-applying member 45 is a torsion spring or a leaf spring, having an elastic arm that abuts against the movable gear 43 to apply an elastic force. In this embodiment, the force-applying member 45 is a torsion spring with two elastic arms, one abutting against the movable gear 43 and the other against the housing 1. In this embodiment, the movable gear 43 is disengaged from the driven gear 44 by overcoming the spring force of the force-applying member 45. In another embodiment, the force-applying member 45 is configured to apply an elastic force to the movable gear 43 to maintain it in the separated position. When the operating member 41 moves from the first position to the second position along the first direction, it drives the movable gear 43 to overcome the elastic force and slide to the coupling position. This embodiment releases the movable gear 43 from the spring force of the force-applying member 45. In this embodiment, when the external force on the operating member 41 is removed, the force-applying member 45 drives the movable gear 43 to the separated position from the driven gear 44 in real time, resulting in more timely separation and better prevention of the driven gear 44 from reversing. In this embodiment, when the operating member 41 moves along the first direction, there is a small sliding distance for the movable gear 43 to move from the separated position to the coupling position. During this distance, the driven gear 44 is not driven, i.e., the operating member 41 has a small idle stroke. In the embodiments described above, the elastic force provided by the return spring 413 is greater than the elastic force applied to the movable gear 43 by the force-applying member 45.
[0076] In some embodiments, the movable gear 43 is a double-layered tower gear with a coaxial small-diameter toothed disc 431 and a large-diameter toothed disc 432. The small-diameter toothed disc 431 of the movable gear 43 meshes with the driven gear 44, and the large-diameter toothed disc 432 of the movable gear 43 meshes with the large-diameter toothed disc 422 of the actuating gear 42. The arrangement of the actuating gear 42 and the movable gear 43 can amplify the rotation angle of the actuating gear 42 during the movement of the operating member 41 from the first position to the second position, which is smaller than the rotation angle of the driven gear 44.
[0077] The driven gear 44 is coaxially and relatively fixedly connected to the winding shaft 140. In this embodiment, the driven gear 44 and the winding shaft 140 are connected by a coupling structure. Specifically, the gear shaft of the driven gear 44 is provided with a polygonal column, and the lower end of the winding shaft 140 is provided with a polygonal sleeve. The polygonal column is inserted into the polygonal sleeve to achieve relative fixation of the two in the rotation direction.
[0078] Please refer to this carefully. Figure 7This is a schematic diagram of the operation of the transmission mechanism during the process of the operating member 41 moving along the first direction under the operation force: At this time, the pressing part 411 of the operating member 41 is subjected to the force as shown by the arrow above it, and the rack part 412 of the operating member 41 rotates inward as shown by the arrow above it. The actuating gear 42 rotates clockwise as shown by the arrow in the figure. At this time, the movable gear 43 is pushed to translate towards the direction close to the driven gear 44 and meshes with the driven gear 44. The driven gear 44 rotates clockwise as shown by the arrow in the figure, driving the winding shaft 140 to rotate, so as to pull the backing paper 72 to move, thereby realizing the peeling and output of the sticker.
[0079] Please refer to this carefully. Figure 8 The diagram illustrates the operation of the transmission mechanism during the process of the operating member 41 being released from its operating force and being driven by the return spring 413 to move in the second direction to return to the first position. At this time, the rack portion 412 of the operating member 41 is subjected to a force as indicated by the arrow above it. The pressing portion 411 of the operating member 41 moves outward as indicated by the arrow above it. The actuating gear 42 rotates counterclockwise as shown by the arrow in the diagram. At this time, the movable gear 43 is pushed to translate away from the driven gear 44 and disengages from the meshing of the driven gear 44. The rotation of the movable gear 43 driven by the actuating gear 42 cannot be transmitted to the driven gear 44, meaning the driven gear 44 will not rotate in the opposite direction. The winding shaft 140 does not move, thus preventing the wound backing paper from loosening during the resetting process of the operating member 41, which would prevent the sticker from being output during the next press.
[0080] It should be noted that this embodiment is illustrated using the example of the movable gear 43 and the driven gear 44 being able to disengage. Understandably, in other embodiments, disengagement can be achieved at any point in the transmission chain between the operating member 41 and the winding shaft 140. It should also be noted that this embodiment uses the translation of the movable gear 43 to switch between engagement and disengagement. In other embodiments, this can also be achieved through a ratchet structure. For example, in some embodiments, the one-way clutch device is a one-way bearing, i.e., an overrunning clutch, which engages with a transmission gear within the transmission mechanism. The one-way bearing can disengage from the winding shaft 140 and rotate freely in one direction, while being locked to the winding shaft 140 in the opposite direction, with both rotating synchronously.
[0081] As described above in the specific embodiment, the manual sticker dispenser A of this embodiment includes a winding shaft 140, a transmission mechanism, and an operating member 41. The operating member 41 is configured to move along a first direction driven by an operating force, and to move along a second direction opposite to the first direction when the operating force is released. During the movement of the operating member 41 along the first direction, a continuous power transmission chain is formed between the operating member 41, the transmission mechanism, and the winding shaft 140 to drive the winding shaft 140 to rotate and wind the backing paper. During the movement of the operating member 41 along the second direction, a one-way clutch device disconnects the power transmission, preventing the winding shaft 140 from reversing. Therefore, sticker output can be achieved by manually applying force to the operating member 41, without the need for electrical components, which reduces costs and enhances operability and entertainment value.
[0082] Please see Figures 9 to 15 The present invention discloses an electric sticker dispenser B, which is used to peel stickers 811 off sticker roll 81. The stickers 811 are peelably attached to backing paper 812 and wound into sticker roll 81. The electric sticker dispenser B is configured to peel the stickers 811 from the backing paper 812 during the conveying of the stickers 811 and output them from the sticker output port 210.
[0083] The electric sticker dispenser B includes a housing 2, a motor 5, a winding shaft 240, a transmission mechanism 53, a power switch 51, and a starting element 52.

The housing 2 has a first cavity 24 and a second cavity 25. A strip of backing paper 812 with a sticker 811 attached is wound into a roll or folded into a stack and placed in the first cavity 24. The output port 210 connects the first cavity 24 with the outside of the housing 2, so that the sticker 811 can be conveyed from the first cavity 24 to the output port 210 and partially exposed on the outside of the housing 2 for the user to remove the sticker 811; the transmission mechanism 53 is placed in the second cavity 25. In some embodiments, the housing 2 includes an upper cover 22, a main body shell 21, and a lower cover 23, wherein the upper cover 22 and the lower cover 23 are both plate-shaped, and the main body shell 21 is a box-shaped structure with a compartment. The housing 2 has at least one outer peripheral plate, which defines the first cavity 24 and the second cavity 25 within the housing 2. In some embodiments, the main body shell 21 includes an outer peripheral plate forming a peripheral wall and a bottom wall connected to the outer peripheral plate. The upper and lower ends of the outer peripheral plate and the bottom wall respectively form a first cavity 24 and a second cavity 25. An upper cover 22 is disposed on the upper opening of the main body shell 21 to cover the first cavity 24; a lower cover 23 is installed on the bottom wall of the main body shell 21, and a second cavity 25 for mounting the transmission mechanism 53 is formed between the lower cover 23 and the bottom wall of the main body shell 21.
[0085] The housing 2 has a cover 241 extending into the first cavity 24. The cover 241 is cylindrical with an opening facing downwards. Specifically, the cover 241 extends upwards from the bottom wall of the main housing 21, forming an opening at its connection with the bottom wall, so that at least a portion of the motor 5 can be inserted into the cover 241 through the opening to extend into the first cavity 24. The shape and size of the cover 241 are configured to accommodate the sticker roll 81 and to be rotatable about the cover 241. Specifically, the sticker roll 81 has a central positioning hole 82, and the cover 241 is configured to pass through the central positioning hole 82 to position the sticker roll 81. The radial dimension of the cover 241 is smaller than the radial dimension of the central positioning hole 82 to ensure that the sticker roll 81 can be fitted into the central positioning hole 82 of the sticker roll 81. In some embodiments, the radial dimension of the central positioning hole 82 is set to be significantly larger than the radial dimension of the housing 241, such that after the amount of backing paper 812 and sticker 811 wound around it decreases, the sticker roll 81 can be eccentrically offset to one side relative to the housing 241, thereby facilitating the transport of the sticker 811. The housing 241 is configured to be generally cylindrical to allow the sticker roll 81 to rotate on the housing 241. The housing 241 is provided with a clearance portion configured to form a pick-up space (not shown) between itself and the wall of the central positioning hole 82, from which the sticker roll 81 is adapted to be pinched and removed. In some embodiments, at least a portion of the motor 5 is disposed within a housing 241. To facilitate installation and alignment with the motor 5, the housing 241 is configured as a cylindrical tube with a vertical plane on its peripheral wall, forming the clearance portion. The motor 5 has a positioning portion (e.g., a plane on the peripheral wall of the motor 5) corresponding to the clearance portion. The positioning portion cooperates with the clearance portion to fix the motor 5 and the housing relative to each other in the circumferential direction, and the motor 5 is positioned and installed within the housing 241. In some embodiments, the electric sticker dispenser B is whistle-shaped, and when viewed from upstream to downstream in the sticker conveying direction, the external dimensions of the electric sticker dispenser B gradually decrease.
[0086] Please see Figures 12 to 15As shown, the winding shaft 240 can wind the backing paper 812 to convey the sticker 811 to the output port 210. The motor 5 outputs rotational power and is connected to the winding shaft 240 through the transmission mechanism 53 to drive the winding shaft 240 to rotate, thereby pulling the backing paper 812 to realize the conveying and peeling of the sticker 811. After peeling off the sticker 811, the backing paper 812 is wound on the winding shaft 240 to form a backing paper roll 83. The body of the motor 5 is located in the cover 241 inside the first cavity 24. The output shaft of the motor 5 faces downward and is located between the lower cover 23 of the housing 2 and the bottom wall of the main body housing 21. The lower end of the winding shaft 240 is also located between the lower cover 23 of the housing 2 and the bottom wall of the main body housing 21. The transmission mechanism 53 is located between the lower cover 23 of the housing 2 and the bottom wall of the main body housing 21 and is connected to the output shaft of the motor 5 and the winding shaft 240. The transmission mechanism 53 includes a gear set connected between the motor 5 and the winding shaft 240. The gear set includes a driven gear coupled to the winding shaft 240, and the lower end of the winding shaft 240 is provided with a sleeve portion 2401 that meshes with the driven gear. Specifically, in some embodiments, the gear set includes a first gear 531, a second gear 532, a third gear 533, and a fourth gear 534, where the second gear 532 to the fourth gear 534 are all double-layered gears. The first gear 531 is sleeved on the output shaft of the motor 5. The second gear 532 meshes with the first gear 531, the third gear 533 meshes with the second gear 532, and the fourth gear 534 meshes with the third gear 533. The fourth gear 534 is the driven gear as described above, and the inner wall surface of the sleeve portion 2401 of the winding shaft 240 is provided with a toothed structure to mesh with the fourth gear 534. The second gear 532 is fixedly mounted on a second gear shaft 5321, the third gear 533 is fixedly mounted on a third gear shaft 5331, and the fourth gear 534 is fixedly mounted on a fourth gear shaft 5341. The gear shafts are used to support and mount the corresponding gears between the lower cover 23 and the bottom wall of the main body shell 21. The end of the fourth gear shaft 5341 facing the winding shaft 240 is interference-fitted into the winding shaft 240 to ensure a reliable connection between the fourth gear 534 and the winding shaft 240.
[0087] Please see Figures 16 to 18 This is another embodiment of the electric sticker dispenser C disclosed in this invention. Components identical to those in the previous embodiment will not be described again. In some embodiments, the electric sticker dispenser C may further include a photoelectric device 6 and a light-shielding part 63. The photoelectric device 6 acquires the output information of the sticker based on a photoelectric signal, and is configured close to the output port 210. The light-shielding part 63 is used to block external light from entering the photoelectric device 6 through the output port 210, and is configured to prevent the external light from interfering with the photoelectric signal.
[0088] Furthermore, a light-shielding portion 63 is formed at the edge of the output port 210 and extends from the output port 210 toward the photoelectric device 6. An anti-sticking portion 631 is provided on the surface of the light-shielding portion 63 opposite to the adhesive surface of the sticker 811. The anti-sticking portion 631 is a raised rib or a raised dot, and the top of the raised rib or raised dot is formed with a blade.
[0089] An operating circuit board is installed inside the main body shell 21. The photoelectric device 6 is mounted on the operating circuit board. A cover plate 61 is provided on the main body shell 21 to cover the operating circuit board. The cover plate 61 has a clearance hole 62 to allow the photoelectric device 6 to be exposed. The clearance hole 62 is used to prevent the photoelectric device 6 from being blocked by the cover plate 61. The cover plate 61 covers most of the operating circuit board, thus protecting it.
[0090] The electric sticker dispenser C provided in this embodiment includes a photoelectric device 6 located near the output port 210. The photoelectric device 6 is used to detect sticker output information, which facilitates the improvement of intelligent control and intelligent prompts of the electric sticker dispenser B. The electric sticker dispenser C includes a light-shielding part 63, which is configured to block external light from entering the photoelectric device 6 from the output port 210, so as to prevent interference with its detection accuracy, making the detection more accurate, avoiding misjudgment, and improving the accuracy of intelligent control and prompts of the electric sticker dispenser B.
[0091] Please see Figures 30 to 32 In some embodiments, the sticker roll 81 includes a rollable backing paper 812 and a sticker 811 peelably adhered to the backing paper 812. The sticker roll 81 conveys the sticker to the output port along the conveying path direction z. The sticker 811 includes a face layer 8111 and an adhesive backing layer 8112, the back side of the face layer 8111 and one side of the adhesive backing layer 8112 are bonded together, and a first adhesive force exists between the face layer 8111 and one side of the adhesive backing layer 8112. The backing paper 812 includes a substrate 8122 and a release layer 8121 thereon, the release layer 8121 having a smooth surface treated with release properties, the other side of the adhesive backing layer 8112 and the surface of the release layer 8121 are bonded together, and a second adhesive force exists between the adhesive backing layer 8112 and the other side of the release layer 8121, wherein the first adhesive force is greater than the second adhesive force. Understandably, the sticker 811 and the backing paper 812 are temporarily adhered by the adhesive layer 8112. When the sticker 811 and the backing paper 812 are peeled off, one side of the face material layer 8111 and the adhesive layer 8112 will not separate, but the other side of the adhesive layer 8112 will separate from the release layer 8121, without damaging the sticker 811 and the backing paper 812. The first adhesive force and the second adhesive force refer to the adhesive force per unit area perpendicular to the adhesive layer 8112.
[0092] The backing paper 812 includes a substrate 8122 and a release layer 8121 thereon. The substrate 8122 may include, but is not limited to, common kraft paper, wood pulp paper, glucono paper, translucent or transparent paper, cloth, or plastic film. The release layer 8121 is coated on one or both sides by an organic or inorganic release agent, which may include, but is not limited to, various silicone resins or non-silicone materials with release properties. The backing paper 812 is a one-piece molded strip without tear lines or dotted lines. The backing paper 812 can be wound from one end along the long axis of the strip and wound into a paper roll 81 with a central positioning hole 82. A plurality of stickers 811 are peelably attached to the backing paper 812. The plurality of stickers 811 are arranged at intervals along the winding direction. The sticker roll 81 that can be wound along the winding direction is wound outward to form a sticker roll 81. The stickers 811 are located on the outside of the sticker roll 81, that is, the outermost layer of the sticker roll 81 exposes the face material layer 8111.
[0093] Please see Figures 19 to 24 This invention discloses a sticker dispenser D with a sticker roll carrier, which is used to dispense stickers 811. The stickers 811 are peelably adhered to backing paper 812 and wound into sticker rolls 81. The sticker dispenser D includes a housing 3, a top cover 32, and a sticker roll carrier 9. The housing 3 includes a first cavity 34 with an opening; the sticker roll carrier 9 is used to hold the sticker rolls 81 and is assembled in the first cavity 34; the top cover 32 covers the opening of the first cavity 34 and is detachably connected to the housing 3 to confine the sticker roll carrier 9 within the first cavity 34.
[0094] In the sticker machine provided in this application, the sticker roll carrier 9 does not serve as an external surface, but only as a carrier for the sticker roll 81 and an output device for the stickers 811. Therefore, there is more room for choice in the materials used to manufacture the sticker roll carrier 9, and the manufacturing precision of the sticker roll carrier 9 can be reduced, thereby reducing costs. When the sticker roll 81 is used up, the top cover 32 is opened to replace the new sticker roll carrier 9, and then the top cover 32 is closed again. The top cover 32 is used as part of the external components for a long time without being replaced, which reduces the number of parts that need to be replaced when the sticker roll 81 is replaced, further reducing the operating costs.
[0095] Please see Figures 23 to 24 and Figures 33 to 34The sticker roll carrier 9 includes an upper cover plate 91 and a lower cover plate 92 disposed opposite to each other, and a connecting post 93 and a winding shaft 94 disposed between the upper cover plate 91 and the lower cover plate 92. The connecting post 93 is used for mounting the sticker roll 81 through the central positioning hole 82. The winding shaft 94 is detachably disposed between the upper cover plate 91 and the lower cover plate 92 and can be fixed to the other end of the backing paper 812 to wind the backing paper 812 after peeling off the sticker 811 to form a backing paper roll 83. The sticker roll carrier 9 also includes a sticker conveying section 95 and a turning and peeling section 96 disposed between the upper cover plate 91 and the lower cover plate 92. In this process, on the conveying path of the backing paper 812 from the socket post 93 to the winding shaft 94, the sticker conveying unit 95 is disposed between the socket post 93 and the turning peeling unit 96 to convey the sticker to the turning peeling unit 96; the turning peeling unit 96 is disposed between the sticker conveying unit 95 and the conveying path of the winding shaft 94 to convey the backing paper 812 in a direction different from the travel direction of the sticker 811, so that the sticker 811 is peeled off from the backing paper 812.
[0096] For further details, please refer to Figure 23 and Figure 24 The upper cover plate 91 and the lower cover plate 92 of the support frame can be separate components, with the connecting post 93, the sticker conveying part 95, and the turning and peeling part 96 disposed therebetween. At least one of the connecting post 93, the sticker conveying part 95, and the turning and peeling part 96 is provided with a hook, a groove 930, a positioning protrusion, or a positioning recess 9501, and the upper cover plate 91 or the lower cover plate 92 of the support frame is provided with a mating part that engages or inserts with the hook, groove 930, positioning protrusion, or positioning recess 9501.
[0097] In some embodiments, the example is provided where the connecting post 93, the sticker conveying section 95, and the deflecting peeling section 96 are all integrally formed with the lower cover plate 92 of the support frame. The lower cover plate 92 of the support frame is a horizontally extending thin plate, and the connecting post 93, the sticker conveying section 95, and the deflecting peeling section 96 are all vertically upward extending from the thin plate. The lower cover plate 92 of the support frame, the connecting post 93, the sticker conveying section 95, and the deflecting peeling section 96 are all plastic parts, which can be integrally injection molded.
[0098] In some embodiments, the socket post 93 is a hollow post with a slot 930 on its peripheral wall. The sticker roll carrier 9 also includes an inner limiting part 950 located inside the sticker output belt between the upper cover plate 91 and the lower cover plate 92 of the carrier. The inner limiting part 950 is a hollow triangular prism extending vertically upward from the lower cover plate 92 of the carrier, and the triangular hole at its upper end forms a positioning recess 9501. The hollow triangular prism is only an example. The bottom edge of the hollow triangular prism and the sticker conveying part 95 are located on both sides of the conveying path. The sticker conveying part 95 and the bottom edge of the hollow triangular prism form an upstream limit for the conveying path of the backing paper 812 and the sticker 811.
[0099] Please see Figure 34 In some embodiments, the deflection and peeling section 96 includes an outer limiting section 960 and a guide structure 961. The outer limiting section 960 and the guide structure 961 are sheet-like structures extending vertically upward from the lower cover plate 92 of the support frame. A peeling point is formed at the junction of the outer limiting section 960 and the guide structure 961. At the peeling point, the direction of the conveying path of the sticker 811 and the backing paper 812 changes, forming a structure for peeling the backing paper 812 and the sticker 811. Specifically, after the winding shaft 94 and the other end of the backing paper 812 are fixed, a pulling force can be provided to make the backing paper 812 travel along the conveying path. After the backing paper 812 is subjected to the pulling force, it first travels from the inner limiting section 950 to the sticker conveying section 95, and then travels to the junction. At this time, the direction of travel of the backing paper 812 changes to travel towards the winding shaft 94, and is wound on the winding shaft 94 to form a backing paper roll 83. A peeling pull force is provided at the peeling point, which is greater than the second adhesive force. Since the remaining portion of the sticker 811 that has not yet reached the peeling point is still subjected to a pull force provided by the backing paper 812 along the conveying path, this pull and / or push force causes the sticker 811 to continue moving in its original direction of travel. At the peeling point, the backing paper 812 and the sticker 811 will begin to peel due to their different directions of travel. The peeling pull force refers to the force perpendicular to the adhesive backing layer 8112.
[0100] In some embodiments, an acute angle is formed between the outer limiting portion 960 and the guide structure 961. This acute angle is designed to provide effective peeling force. However, it is understood that the vertically extending sheet is merely illustrative. As long as the configuration of the outer limiting portion 960 and the guide structure 961 allows the backing paper 812 to change its direction of travel, a peeling point is formed at the junction, generating peeling force so that the backing paper 812 and the sticker 811 begin to peel off at the peeling point. It is understood that the formation between the outer limiting portion 960 and the guide structure 961 is not limited to an acute angle; for example… Figures 35 to 37As shown, as long as the configuration of the outer limiting part 960 and the guide structure 961 can change the direction of travel of the backing paper 812, and a peeling force is generated at the interface to form a peeling point, so that the backing paper 812 and the sticker 811 at the peeling point will begin to peel off, they all fall within the scope of protection of the turning peeling part 96 of the present invention.
[0101] Please see Figure 33 In some embodiments, the lower cover plate 92 of the support frame is further provided with a mounting post 97 at the end away from the sleeve post 93. The mounting post 97 and the sleeve post 93 are used together to connect with the upper cover plate 91 of the support frame. The mounting post 97 may also include a limiting part 970, which is provided relative to the turning and peeling part 96. There is a gap between the limiting part 970 and the guide structure 961 through which the liner paper 812 can pass. The limiting part 970 is provided between the turning and peeling part 96 and the winding shaft 94. The limiting part 970 is to maintain a fixed direction of travel for the liner paper 812 when it passes through the gap, so that the direction of travel will not change as the liner paper 812 continues to wind and thicken on the winding shaft 94.
[0102] Please see Figure 24 In some embodiments, the upper cover plate 91 of the support frame is provided with a docking hook 911 that mates with the slot 930, a docking protrusion 913 that inserts into the positioning recess 9501, and a locking post 912 that mates with the mounting post 97; the cooperation of these structures allows the upper cover plate 91 of the support frame to be snapped onto the lower cover plate 92 of the support frame. The docking hook 911, the docking protrusion 913, and the locking post 912 constitute the docking part. In other embodiments, the hook, slot 930, positioning protrusion or positioning recess 9501, and the docking part that mates with them can also be in other forms; in still other embodiments, the hook, slot 930, positioning protrusion or positioning recess 9501 can also be provided on the turning and peeling part 96. It is understandable that as long as the connecting post 93, winding shaft 94, sticker conveying part 95, inner limiting part 950, turning and peeling part 96, outer limiting part 960, guide structure 961, mounting post 97 and pressure limiting part 970 are arranged between the upper cover plate 91 and the lower cover plate 92 of the support frame, and the sticker roll 81 can form a conveying path from the connecting post 93 to the winding shaft 94 therebetween, the upper cover plate 91 and the lower cover plate 92 of the support frame are separate parts, or the upper cover plate 91 and the lower cover plate 92 of the support frame are integrally formed parts, or all of the above components are separate parts, or any two of the above components are integrally formed parts, it does not affect the spirit of the present invention. Similarly, it can be understood that the above-mentioned components are the preferred configuration for use in this embodiment. Even if some of these components are missing, it is still possible to achieve the following: the sticker roll 81 forms a transport path from the socket post 93 to the winding shaft 94, and the backing paper 812 and the sticker 811 can be peeled off at the peeling point. All of these are within the scope of protection of this invention.
[0103] Please see Figures 20 to 22 The edges of the upper cover plate 91 and the lower cover plate 92 of the support frame are open, and the sticker roll 81, fitted onto the connecting post 93, is restricted within the housing 3 by the inner wall of the first cavity 34 to prevent it from becoming loose. In other words, in this embodiment, only the aforementioned discretely distributed connecting posts 93, winding shaft 94, sticker conveying part 95, turning and peeling part 96, and mounting post 97 are provided between the upper cover plate 91 and the lower cover plate 92 of the support frame, without a continuous wall. This makes the sticker roll support frame 9 simple in structure, uses less material, and is inexpensive. Since the sticker roll support frame 9 itself does not have a continuous wall or a cavity, the sticker roll 81 fitted onto the connecting post 93 can be restricted within the housing 3 by the inner wall of the first cavity 34 to prevent it from becoming loose.
[0104] Please continue reading. Figure 23 and Figure 24 The winding shaft 94 needs to be driven to rotate by the drive mechanism 10. Therefore, the winding shaft 94 is an independent component, rotatably mounted between the upper cover plate 91 and the lower cover plate 92 of the support frame. The winding shaft 94 and the housing 3 are provided with a coupling mechanism that cooperates with each other. The coupling mechanism includes a convex shaft on one of the winding shaft 94 and the housing 3 and a bushing 98 on the other. The drive mechanism 10 transmits power to the winding shaft 94 through the cooperation of the convex shaft and the bushing 98 to drive the winding shaft 94 to rotate and wind the backing paper. In this embodiment, the convex shaft or bushing 98 on the winding shaft 94 is connected to the winding shaft 94 by a snap-fit 980. Specifically, in this embodiment, a convex shaft is disposed on the housing 3, and a bushing 98 is disposed on the winding shaft 94. The bushing 98 has a polygonal shaft hole exposed below the lower cover plate 92 of the support frame. The bushing 98 has a buckle 980 protruding above the lower cover plate 92 of the support frame. The winding shaft 94 has a locking hole 940 corresponding to the buckle 980. The bushing 98 has a flange edge. The buckle 980 of the bushing 98 passes through the lower cover plate 92 of the support frame and is snapped into the winding shaft 94. The flange edge of the bushing 98 is confined on the lower cover plate 92 of the support frame. Together, they realize the connection of the winding shaft 94, prevent the winding shaft 94 from tilting in a direction deviating from its own axis, and ensure the reliability of the connection. The housing 3 includes a positioning post 342 inserted into the sleeve post 93. The sleeve post 93 is set on the lower cover plate 92 of the support frame. The sleeve post 93 is a hollow post. The lower cover plate 92 of the support frame has a sleeve positioning hole 921 that communicates with the hollow part of the sleeve post 93. The positioning post 342 can pass through the sleeve positioning hole 921 and be inserted into the sleeve post 93.
[0105] Please see Figures 20 to 24The housing 3 includes an insertion positioning part 311 and a snap-fit fixing part 312 disposed at opposite edges of the opening of the first cavity 34. The upper cover 32 is correspondingly provided with an insertion mating part 321 and an elastic snap-fit part 322. The upper cover 32 is connected to the housing 3 by the insertion mating part 321 engaging with the insertion positioning part 311, and the elastic snap-fit part 322 engaging with the snap-fit fixing part 312. In this embodiment, the insertion positioning part 311 is a slot, the snap-fit fixing part 312 is a locking block, and the insertion mating part 321 is an insert.
[0106] After the sticker roll carrier 9 is assembled into the first cavity 34 of the housing 3, the insertion and mating part 321 on the upper cover 32 is inserted obliquely into the insertion and positioning part 311 of the housing 3. Then, one end of the upper cover 32 with the elastic buckle part 322 is pressed, so that the elastic buckle part 322 and the snap-fit fixing part 312 are assembled. When it needs to be removed, press the elastic buckle part 322, lift the upper cover 32, and take out the sticker roll carrier 9 from the first cavity 34 for replacement. Furthermore, the housing 3 may be provided with an elastic ejector to eject the sticker roll carrier 9 a certain distance when the upper cover 32 is separated from the housing 3, so as to facilitate removal.
[0107] In some embodiments, the housing 3 includes an outer shell and a lower cover 33. The outer shell includes a peripheral sidewall 313 and a partition wall 341. An outlet 310 is provided on the peripheral sidewall 313. The partition wall 341 is disposed between the upper edge and the lower edge of the peripheral sidewall 313 to enclose a first cavity 34 located above the partition wall 341 and a second cavity 35 located below the partition wall 341. A drive mechanism 10 for driving the winding shaft 94 to rotate is installed in the second cavity 35. The lower cover 33 covers the lower edge of the peripheral sidewall 313.
[0108] In some embodiments, the drive mechanism 10 is a manual drive mechanism, which includes a lever and components such as a gear set, clutch, and reset member driven by the lever. By pressing the lever, the winding shaft 94 can be rotated to wind the backing paper and thus peel off the sticker.
[0109] Please see Figures 25 to 29This is a schematic diagram of a sticker dispenser E with a sticker roll carrier according to another embodiment of the present invention. Components identical to those in the previous embodiment will not be described again. The main difference between this embodiment and the previous embodiment lies in the connection structure between the upper cover 32 and the housing 3. Specifically, the overall structure of the sticker roll carrier 9 in this embodiment is basically the same as that in the previous embodiment, except that the structure of the upper cover plate 91 of the carrier is different. In this embodiment, the upper cover plate 91 of the carrier is provided with a through hole 910. In some embodiments, the housing 3 includes a positioning post 342 inserted into the sleeve post 93. The top of the positioning post 342 is provided with an operation button 343 and a second latching member 344 operated by the operation button 343. The upper cover 32 is provided with a through hole 323 for the operation button 343 to be exposed and a first latching member 324 that engages with the second latching member 344. In this embodiment, the first fastener 324 is a vertically extending fastener piece with a slot. The second fastener 344 is held in the slot of the first fastener 324 by the action of a spring to maintain the fastening state. The operation button 343 can disengage the second fastener 344 from the slot and release the fastening state by moving the second fastener 344.
[0110] When assembling the sticker machine of this embodiment, the sticker roll carrier 9 is first assembled into the first cavity 34 of the housing 3. Then, the upper cover 32 is pressed down to the opening of the first cavity 34 of the housing 3. During the pressing down of the upper cover 32, the first latching member 324 pushes the second latching member 344, which has an inclined surface, to move laterally and compress the spring until the slot on the first latching member 324 is aligned with the second latching member 344. Under the action of the spring force, the second latching member 344 resets and engages with the slot on the first latching member 324, thus connecting the upper cover 32. When disassembly is required, the operating button 343 is turned to disengage the second latching member 344 from the first latching member 324, and the upper cover 32 and the sticker roll carrier 9 in the first cavity 34 can be removed. Furthermore, an elastic ejector can be provided inside the housing 3 to eject the sticker roll carrier 9 a certain distance when the latch between the upper cover 32 and the housing 3 is released, so as to facilitate removal.
[0111] Please see Figure 29 As shown, in some embodiments, the drive mechanism 10 is electrically driven, including a motor, a battery powering the motor, and a gear set driven by the motor. The main body of the motor is housed within the positioning post 342 of the housing 3 to make efficient use of space. In this embodiment, a button 314 is provided on the peripheral sidewall 313 of the housing 3 to start the motor; a charging port 331 is provided on the lower cover 33 to charge the battery. Parts not mentioned in this embodiment are similar to those in the above embodiments and can be referred to the sticker dispenser D with a sticker roll carrier in the embodiment.
[0112] Please see Figure 38 and Figure 39In another embodiment, the structure is basically the same as the above embodiment, except that the upper cover plate 91 and the lower cover plate 92 of the sticker roll carrier 9 are respectively provided with openings 914 and 921 at their relative positions. The opening 914 of the upper cover plate 91 is located between the through hole 910 and the winding shaft 94, and the opening 921 of the lower cover plate 92 is opposite to the opening 914 of the upper cover plate 91. The user can move the sticker rolls 71 and 81 through the openings 921 and / or 914, so that the sticker rolls 71 and 81 rotate under the action of friction and become more compact, thereby overcoming the problem of the sticker rolls 71 and 81 being loose after installation.
[0113] As described above in the specific embodiments, the sticker dispenser with a sticker roll carrier provided in this application includes a housing 3, a top cover 32, and a sticker roll carrier 9. The sticker roll carrier 9 carries sticker rolls 81 and is assembled in the first cavity 34 of the housing 3. The top cover 32 covers the opening of the first cavity 34 and is detachably connected to the housing 3 to confine the sticker roll carrier 9 within the first cavity 34 of the housing 3. This arrangement means that the sticker roll carrier 9 does not serve as an external surface but only as a carrier for the sticker rolls 81 and for dispensing stickers. Therefore, there is more room for choice in the material used for the sticker roll carrier 9, and the manufacturing precision of the sticker roll carrier 9 can be reduced, thereby reducing costs. When the sticker rolls 81 are used up, the top cover 32 is opened to replace the new sticker roll carrier 9, and then the top cover 32 is closed again. The top cover 32 is used as part of the external components for a long time without replacement, reducing the number of parts that need to be replaced when the sticker rolls 81 are replaced, further reducing the operating costs.
[0114] As described above, the drive mechanism 10 can be a manual drive mechanism or an electric drive mechanism. The parts of the manual drive mechanism not mentioned in this embodiment are similar to those in the above embodiments and can be set up as described in the manual sticker dispenser A embodiment. The parts of the electric drive mechanism not mentioned in this embodiment are similar to those in the above embodiments and can be set up as described in the electric sticker dispensers B and C embodiments. The parts of the sticker roll carrier 9 that are the same in all embodiments will not be described again.
[0115] Although described above with reference to specific embodiments, the scope of the invention is not limited thereto. The foregoing detailed description is intended to be illustrative rather than restrictive, and it should be understood that the appended claims, including all equivalents, are intended to define the scope of the invention. The claims should not be construed as limited to the described order or elements unless otherwise stated. Therefore, all embodiments falling within the scope and spirit of the appended claims and their equivalents are claimed by the present invention.
