Description

Technical Field

[0001] This application relates to the field of label distribution technology, and in particular to a label distribution device. Background Technology

[0002] A label dispensing device is a type of device used to automatically peel off and dispense labels while simultaneously winding up the remaining backing paper. Its basic working principle involves a drive mechanism that rotates a winding component, thereby continuously winding the peeled backing paper.

[0003] In existing label dispensing devices, the winding component is often connected to the drive shaft by a circumferential limiting fit. For example, the outer circumferential surface of the drive shaft and the inner wall surface of the winding component are both flat keys, splines, or other circumferential keyway structures, and the drive shaft is embedded in the inner cavity of the winding component.

[0004] While this structure can meet the winding requirements, it has certain shortcomings in practical use. Specifically, when the label roll needs to be replaced, the winding component often needs to be separated from the drive component. However, due to the circumferential limiting fit between the two, the drive shaft and the winding component are completely locked in the circumferential direction. The friction and resistance that need to be overcome during disassembly are too great, making it difficult to separate the winding component from the drive component. This inconveniences users when changing label rolls and affects the efficiency of equipment use and maintenance.

[0027] This utility model proposes a label distribution device.

[0028] In this embodiment of the utility model, please refer to Figures 1 to 13 The label 11 is peelably adhered to the backing paper 12 and wound into a roll 10 of label 11. The label dispensing device includes a box 20, a drive mechanism 30, a paper roll mechanism 40, and a cover plate 50. The box body 20 has an opening 21 that communicates with its inner cavity; the side wall of the box body 20 has an outlet 22. The drive mechanism 30 includes a drive shaft 31, and the end face of the drive shaft 31 facing the opening 21 is provided with a first drive part 32; The paper roll mechanism 40 includes a positioning element 41, a winding element 42, and a deflecting and peeling element 43. The positioning element 41 is rotatably mounted on the label roll. The winding element 42 is driven to pull the label roll to rotate and wind up the backing paper 12. The deflecting and peeling element 43 cooperates with the winding element 42 to change the direction of travel of the backing paper 12, so that the label 11 is partially or completely peeled off from the backing paper 12 and can be output through the output port 22. The paper roll mechanism 40 is detachably assembled into the cavity via the opening 21; the end face of the winding member 42 opposite to the first transmission part 32 is provided with a second transmission part 424, and the first transmission part 32 and the second transmission part 424 are detachably connected in the axial direction of the transmission shaft 31. Furthermore, the first transmission part 32 and the second transmission part 424 are in a circumferential upper limit fit on the transmission shaft 31, and the outer peripheral surface of the second transmission part 424 is exposed to the first transmission part 32. Alternatively, the first transmission part 32 and the second transmission part 424 are arranged radially along the transmission shaft and are in transmission engagement; The cover plate 50 closes the opening 21 to confine the drive mechanism 30 and the paper roll mechanism 40 within the cavity.

[0029] The housing 20 serves as the shell and support structure for the entire label dispensing device, providing an internal cavity for mounting the drive mechanism 30 and the paper roll mechanism 40. The side wall of the housing 20 has an output port 22 for dispensing the label stickers 11.

[0030] The drive mechanism 30 provides power to drive the winding member 42 to rotate, and its core component is the drive shaft 31. One end of the drive shaft 31 is provided with a first transmission part 32, which cooperates with the second transmission part 424 of the winding member 42 to realize drive transmission. The first transmission part 32 and the second rotation part can be a cam and groove, a tooth block and tooth groove, a spline protrusion and spline groove, or a polygonal cross section (such as square or hexagonal fit), etc.

[0031] The paper roll mechanism 40 includes a positioning element 41, a winding element 42, and a deflecting and peeling element 43. The positioning element 41 is used to rotatably mount the label roll, ensuring that the label roll can be pulled and rotated. The positioning element 41 can be a support rod, an L-shaped bracket, a U-shaped bracket, etc. The winding element 42 is used to wind the peeled backing paper 12, ensuring that the label 11 can be smoothly separated from the backing paper 12. The winding element 42 can be a cylindrical roller, a hollow shaft structure, or a segmented clamping structure, etc. The deflecting and peeling element 43 is used to change the travel path of the backing paper 12, causing the label 11 to peel off from the backing paper 12 and be output through the output port 22. The deflecting and peeling element 43 can be a fixed arc-shaped guide plate or a combination of a roller and a pressure plate, etc.

[0032] The cover plate 50 is used to close the opening 21 of the box body 20 during use, restricting and protecting the drive mechanism 30 and the paper roll mechanism 40 to prevent them from loosening or falling off during operation. The cover plate 50 can be a flip-top cover plate 50, a push-pull cover plate 50, a detachable cover plate 50, a snap-on cover plate 50, etc.

[0033] The paper roll mechanism 40 is detachably mounted in the cavity via the opening 21, allowing the user to achieve a continuous supply of the label 11 by directly replacing the paper roll mechanism 40.

[0034] Related technologies typically employ a socket within the winding component 42, allowing the drive shaft 31 to be inserted into the socket. The outer circumferential wall of the drive shaft and the inner circumferential wall of the socket are circumferentially matched to achieve torque transmission. For example, the drive shaft may be equipped with a circumferential keyway structure such as a flat key or spline, allowing the winding component 42 to wind the backing paper 12 whose label 11 has been peeled off. However, because the outer circumferential surface of the drive shaft 31 is nested within the inner circumferential surface of the socket in the winding component 42 during transmission, and the circumferential matching causes them to lock together, the friction and resistance between them are significant when axial separation is needed to replace or maintain the winding component 42, leading to difficulties in disassembly and assembly.

[0035] In this embodiment, reliable circumferential transmission is achieved by the upper limit cooperation of the first transmission part 32 and the second transmission part 424 in the circumferential direction of the transmission shaft 31. At the same time, the outer circumferential surface of the second transmission part is exposed to the first transmission part, so that the second transmission part can be loose relative to the first transmission part in the radial direction of the transmission shaft, and will not lock up. Therefore, the winding shaft and the transmission shaft can be smoothly separated axially, thereby realizing the quick replacement or maintenance of the winding part 42 (paper roll mechanism 40).

[0036] The outer peripheral surface of the second transmission part 424 being exposed to the first transmission part 32 means that the first transmission part 32 and the second transmission part 424 do not obstruct each other radially in the transmission shaft 31, and the peripheral surface of the second transmission part 424 does not constrain the peripheral surface of the first transmission part 32. For example, several transmission structures (such as protrusions, tooth blocks, spline teeth) are formed on the end face of the transmission shaft 31, and are arranged at intervals in its circumferential direction; corresponding transmission structures (such as grooves, tooth grooves, spline grooves) are formed on the end face of the winding part 42, and are also arranged at intervals in the circumferential direction. When the winding part 42 is assembled to the transmission shaft 31, the first transmission part 32 fits into the second transmission part 424, so that the two are mutually limited and matched in the circumferential rotation direction to realize torque transmission; at the same time, the two maintain a pluggable and detachable relationship in the axial direction of the transmission shaft 31, thereby ensuring that the winding part 42 can be easily installed and removed.

[0037] In one example, the first transmission part 32 and the second transmission part 424 can be separably engaged in the radial direction of the transmission shaft 31, which can also achieve stable transmission and facilitate disassembly and assembly. Specifically, the first transmission part 32 is configured to engage with the second transmission part 424 in the working position and disengage from the second transmission part 424 when the paper roll mechanism 40 is installed.

[0038] This invention allows the paper roll mechanism 40 to be detachably assembled into the cavity via the opening 21, enabling users to achieve a continuous supply of labels 11 by directly replacing the paper roll mechanism 40. Simultaneously, the first transmission part 32 and the second transmission part 424 are detachably connected axially on the transmission shaft 31, and the first transmission part 32 and the second transmission part 424 are circumferentially locked together on the transmission shaft 31, with the outer circumferential surface of the second transmission part 424 exposed to the first transmission part 32; or the first transmission part 32 and the second transmission part 424 are circumferentially locked together on the transmission shaft 31, with the outer circumferential surface of the second transmission part 424 exposed to the first transmission part 32. This allows the second transmission part 424 to be loosely positioned relative to the first transmission part 32 radially on the transmission shaft 31, enabling easy axial disassembly of the transmission shaft 31 and the paper roll mechanism 40, thus simultaneously satisfying the requirements of transmission reliability and ease of installation and removal.

[0039] Furthermore, the first transmission part 32 is provided with a plurality of first teeth 321 spaced circumferentially along the transmission shaft 31; the second transmission part 424 is provided with a plurality of second teeth 4241 adapted to the first teeth 321, and each second tooth 4241 is provided between two first teeth 321.

[0040] In this embodiment, the first tooth 321 serves as the active transmission tooth element, outputting the rotational torque of the transmission shaft 31. The second tooth 4241 serves as the driven tooth element, directly meshing with the first tooth 321 to achieve torque transmission while maintaining the circumferential limit of the wound member 42.

[0041] Because the second tooth 4241 directly engages between the first tooth 321, the contact area between the two is large, and the circumferential force is more uniform, ensuring that the wound part 42 and the drive shaft 31 can precisely mesh radially and circumferentially, thereby making the transmission stable. At the same time, this meshing method also avoids the formation of axial fastening, so no excessive axial resistance is generated during disassembly and assembly.

[0042] The tooth tip can be rectangular, trapezoidal, or semi-circular, and there is no limitation here. The tooth groove angle can be right angle or inclined angle to adapt to different assembly precision and torque requirements.

[0043] Furthermore, the first transmission part 32 has a first transmission surface 322, and the second transmission part 424 has a second transmission surface 4242; the first transmission surface 322 and the second transmission surface 4242 are connected in the circumferential direction of the transmission shaft 31 by point contact or line contact.

[0044] In this embodiment, a first transmission surface 322 is disposed on the first transmission portion 32 of the transmission shaft 31. Serving as the radial working surface of the transmission shaft 31, it is used to form contact with the transmission surface of the winding member 42. A second transmission surface 4242 is disposed on the second transmission portion 424 of the winding member 42. Serving as a driven working surface that mates with the first transmission surface 322, it is axially engaged with the transmission shaft 31 to receive driving action. The first transmission surface 322 / second transmission surface 4242 may be a plane, an arc surface, or a splined tooth surface to accommodate different assembly precision and torque requirements.

[0045] Compared to large-area surface contact, point or line contact effectively reduces the contact area, thereby reducing assembly friction and facilitating subsequent assembly and disassembly of the paper roll mechanism 40. Point or line contact also concentrates meshing stress in a more limited area, ensuring the transmission of torque without causing jamming due to uneven force distribution across the entire surface. Furthermore, point or line contact can automatically correct the concentricity of the winding component 42 and the drive shaft 31 through geometric features, reducing deviations caused by machining errors.

[0046] In one example, a local arc or spherical surface may be formed on the first transmission surface 322, and the second transmission surface 4242 is a corresponding plane or concave surface. The geometric relationship between the two makes the contact only formed at one point or a few points or a line.

[0047] In one embodiment, the first tooth 321 has a first guide slope 62 connected to the first transmission surface 322; the second tooth 4241 has a second guide slope 63 connected to the second transmission surface 4242. The first transmission surface 322 of the first tooth 321 is connected to the second transmission surface 4242 of a second tooth 4241, and the first guide slope 62 of the first tooth 321 is opposite to the second guide slope 63 of the other second tooth 4241.

[0048] In this embodiment, the first guide slope 62 and the second guide slope 63 cooperate to correct misalignment and provide guidance, enabling the wound component 42 to automatically align with the drive shaft 31 for easy installation. Specifically, the sliding action of the first guide slope 62 reduces the direct hard collision between the first tooth 321 and the second tooth 4241, thereby preventing assembly jamming or damage. This arrangement ensures that even if the wound component 42 has a slight angular deviation or offset, it can be guided to the correct meshing position under the action of the first guide slope 62 and the second guide slope 63.

[0049] In one embodiment, the winding member 42 is provided with a first mounting groove 423, and the bottom wall of the first mounting groove 423 is provided with a plurality of second teeth 4241; the drive shaft 31 is inserted into the mounting groove; when the first drive part 32 and the second drive part 424 are in circumferential upper limit engagement with the drive shaft 31, there is a gap between the circumferential wall of the drive shaft 31 and the circumferential wall of the first mounting groove 423.

[0050] In this embodiment, by opening a first mounting groove 423 on the winding part 42 and arranging the second transmission part 424 on the bottom wall of the groove, the end face of the transmission shaft 31 and the second transmission part 424 are meshed and limited in the circumferential direction. At the same time, by creating a gap between the circumferential wall of the transmission shaft 31 and the circumferential wall of the mounting groove, the reliability of the transmission is ensured and the frictional resistance during loading and unloading is significantly reduced. Users can quickly and smoothly replace the winding part 42 and the label roll, and the overall ease of operation of the device is further improved.

[0051] The first mounting slot 423 provides a sliding space, allowing the winding component 42 to be easily aligned with the drive shaft 31 along the guide of the first mounting slot 423, reducing the difficulty of manual assembly. When it is necessary to change the label roll during use, it can be easily removed by gently pulling it out along the direction of the first mounting slot 423. In this way, the first mounting slot 423 serves both as a guide for insertion and as a limiting fit.

[0052] In one embodiment, the winding member 42 includes a winding cylinder 421 and a first transmission member 422 detachably and fixedly connected to the winding cylinder 421; the first transmission member 422 is provided with a first mounting groove 423.

[0053] In this embodiment, the winding component 42 adopts a split design, wherein the winding drum 421 serves as the carrier of the backing paper 12 and realizes the winding function. The first transmission component 422, as an independent module, bears the driving transmission action and realizes the transmission of torque of the transmission shaft 31; and due to its detachability, it can be replaced or maintained separately, avoiding the scrapping of the entire winding drum 421 and improving the life and cost utilization of the device; the first mounting groove 423 provided on the first transmission component 422 cooperates with the transmission shaft 31 to form a limiting and transmission, and uses its own shape to guide the transmission shaft 31 to be installed into the groove.

[0054] The first transmission component 422 and the winding drum 421 are detachably fixedly connected, for example, by snap-fit, screw fixing, plug-in, or ring locking, and the specific form is not limited here. The winding drum 421 can be cylindrical, hollow cylindrical, or polygonal, etc.

[0055] In one embodiment, the drive shaft 31 includes a shaft body 311 and a second drive member 312 fixedly connected to the shaft body 311. The end of the second drive member 312 is provided with a first drive portion 32. There is a gap between the peripheral wall of the second drive member 312 and the peripheral wall of the first mounting groove 423.

[0056] In this embodiment, a second transmission component 312 is fixed to the end of the shaft body 311 of the transmission shaft 31, and a first transmission part 32 is formed at the end of the second transmission component 312. Simultaneously, a gap is created between the peripheral wall of the second transmission component 422 and the peripheral wall of the first mounting groove 423, enabling smooth and convenient axial insertion and removal of the winding component 42. With this design, there is no need to overcome significant friction during loading and unloading, allowing users to quickly replace label rolls. Furthermore, since the first transmission part 32 is mounted on the independently replaceable second transmission component 312, users can replace the second transmission component 312 separately if wear occurs, reducing maintenance costs and extending the service life of the entire device. Without affecting circumferential power transmission, the label dispensing device combines ease of loading and unloading, economical maintenance, and structural reliability.

[0057] The gap between the first transmission component 422 and the first mounting groove 423 can be a fixed distance to ensure smooth insertion and removal; the gap between the first transmission component 422 and the first mounting groove 423 can also be gradual. In this way, the gap has a guiding function, which is conducive to automatic alignment and insertion.

[0058] The second transmission component 312 and the shaft body 311 can be detachably fixedly connected, such as by a keyway, snap-fit, or screw connection; or they can be non-detachably fixedly connected, such as by a pin connection or welding. The specific connection method is not limited here.

[0059] In one embodiment, the winding member 42 has a winding peripheral wall for the liner paper 12 to be wound; the winding member 42 includes a first winding member 425 and a second winding member 426 detachably connected on its rotation axis, the outer peripheral wall of the first winding member 425 and the outer peripheral wall of the second winding member 426 together forming the winding peripheral wall.

[0060] In related technologies, the liner paper 12 is often tightly wound around the surface of the winding component 42. When the liner paper 12 is tightly wound, it is difficult for the user to quickly remove it from the winding component 42 when replacing it, and the disassembly process is time-consuming and laborious.

[0061] In this embodiment, the winding component 42 adopts a split design, that is, the first winding component 425 and the second winding component 426 are detachably connected on the rotation axis of the winding component 42. When the user needs to replace or remove the liner paper 12, the winding component 42 can be separated first. After the first winding component 425 and the second winding component 426 are separated, the frictional resistance and clamping effect between the liner paper 12 and the winding component 42 are reduced, and the winding perimeter wall loses complete constraint. At this time, the liner paper 12 is loosened and easy to remove.

[0062] Compared with the existing technology where the winding component 42 is an integral structure, making it difficult to separate the liner paper 12 from the winding component 42, this embodiment designs the winding component 42 as a first winding component 425 and a second winding component 426 that are detachably connected on the rotation axis. When the two are combined, the outer peripheral wall forms a complete winding peripheral wall, realizing the normal winding of the liner paper 12. When it is necessary to remove or replace the liner paper 12, the user can separate the two winding components 42, so that the originally complete winding peripheral wall breaks, thereby allowing the roll of liner paper 12 to loosen naturally and be quickly removed, effectively solving the problem of difficult separation of the liner paper 12 and significantly improving the convenience of operation.

[0063] Furthermore, the first winding member 425 is provided with a plurality of first rods 4251, and the second winding member 426 is provided with a plurality of second rods 4261; the plurality of first rods 4251 and the plurality of second rods 4261 are alternately spaced along the circumference of the winding member 42; the outer peripheral walls of the plurality of first rods 4251 and the plurality of second rods 4261 together form a winding peripheral wall.

[0064] Compared with the axially connected cylinders on the first winding member 425 and the second winding member 426, in this embodiment, the first rod 4251 and the second rod 4261 are arranged alternately and at intervals. The gap between the rods reduces the contact area between the first winding member 425 and the second winding member 426 and the backing paper 12, and the friction between them and the backing paper 12 is also reduced accordingly. Users can more easily separate the first rod 4251 and the second rod 4261.

[0065] The first rod 4251 / the second rod 4261 can be a cylindrical rod, a square rod, or a curved rod, etc., and there is no limitation here.

[0066] In one embodiment, the label dispensing device further includes an elastic ejector 60, which is disposed between the side of the paper roll mechanism 40 away from the opening 21 and the box body 20, so that the elastic ejector 60 elastically acts on the paper roll mechanism 40 in the direction toward the opening 21, and after the cover plate 50 is removed, the paper roll mechanism is ejected a preset distance toward the opening 21.

[0067] In this embodiment, the paper roll mechanism 40 is detachably connected, allowing it to be quickly removed and reinstalled into the box 20, facilitating the replacement and maintenance of the paper label rolls. Detachability can be achieved through methods such as plug-in snap-fit, sliding rail limiting, slot-protrusion engagement, or socketing.

[0068] The elastic ejector 60 is used to eject the paper roll mechanism 40, preventing the user from forcibly pulling the paper roll mechanism 40 out of the tight space by hand, thus improving replacement efficiency and ease of operation. Specifically, when the cover is closed, the elastic ejector 60 is in a compressed state; when the cover is opened, the elastic ejector 60 restores its deformation and generates elastic force, pushing the paper roll mechanism 40 to move towards the opening 21.

[0069] The elastic ejector 60 can be an elastic element in the form of a spring, leaf spring, elastic pad, elastic block (such as a rubber block), or a combination of the above elastic elements with other structural components. The specific installation method of the elastic ejector 60 is not limited here, as long as it can achieve the elastic ejection function of the paper roll mechanism 40. For example, one end of the elastic ejector 60 is confined to the fixed structure of the box body 20, and the other end freely abuts against the paper roll mechanism 40. Specifically, the box body 20 also includes a partition plate 61 disposed within the cavity, dividing the box body 20 into a first chamber for accommodating the paper roll mechanism 40 and a second chamber for accommodating some driving components. An elastic ejector 60, capable of reciprocating between the first and second chambers, is inserted into the partition plate 61. The end of the elastic ejector 60 located in the first chamber abuts against the paper roll mechanism 40.

[0070] In one embodiment, the label dispensing device includes a first paper mechanism 44 and a second paper mechanism 45, both of which employ the paper roll mechanism 40; the first paper mechanism and the second paper mechanism are alternately installed in the box body 20; the dimension of the first paper mechanism in the width direction of the liner paper 12 is larger than the dimension of the second paper mechanism in the width direction of the liner paper 12.

[0071] In this embodiment, the first paper mechanism 44 is used to install and drive the winding of the wider backing paper roll 12; the second paper mechanism 45 is used to install and drive the winding of the narrower backing paper roll 12. By alternating installations, the user can select the appropriate paper roll mechanism 40 as needed to handle label rolls of different widths, improving the flexibility of the device. Simultaneously, this means that the same label dispensing device achieves compatibility with label rolls of different specifications. While ensuring convenient roll changing, it effectively broadens the applicability of the device and improves its versatility and efficiency.

[0072] In one embodiment, the side wall of the housing 20 is provided with an output port 22, and the top wall of the housing 20 is provided with an operation window 23 communicating with the output port 22; at least the portion of the rotating and deflecting stripper 43 adjacent to the output port 22 is exposed in the operation window 23.

[0073] In this embodiment, an operation window 23 is provided on the top wall of the housing 20, which connects to the output port 22. The shape of the operation window 23 can be square, circular, or other shapes, and is not limited here. In this embodiment, the overall shape of the operation window 23 and the output port 22 can be L-shaped. The deflecting peeler is exposed inside the operation window 23, thereby forming a force application space between the output port 22 and the operation window 23. In other words, the force application space is the space above the operation window 23. When the user takes the label 11, due to the pulling force of the winding member 32 below the deflecting peeler, the user grasps the label 11 and applies an upward force, making it easier to peel the label 11 off the backing paper 12, avoiding the backing paper 12 being pulled out additionally due to excessive horizontal pulling force. The operation window 23 and the output port 22 form a continuous paper output space, allowing the user to directly tear or pick up the label 11 from above, making the operation convenient.

[0074] Furthermore, the output port 22 and the operation window 23 extend toward the cover plate 50 to penetrate the box body 20; when the cover plate 50 closes the opening 21, the cover plate 50 blocks the edges of the output port 22 and the operation window 23.

[0075] In this embodiment, when the user needs to replace the label roll, even if the backing paper 12 is pulled out excessively during operation, the paper roll mechanism 40 will not be obstructed from being taken out by the baffles of the output port 22 and the operation window 23. The output port 22 can be a strip-shaped opening, extending horizontally along its length. The lateral dimension of the output port 22 can be set according to the width of the label 11, allowing the label 11 to pass through smoothly. Furthermore, the edges of the output port 22 can be provided with guide bevels or rounded corner structures to prevent the label 11 from being scratched during output.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
