Description

Technical Field

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

[0002] Label peelers are used to peel off labels one by one from a rolled label roll and output them for easy user access. For convenient label roll replacement, existing label peelers typically include a housing and a paper roll carrier. The housing includes a receiving compartment with an open side and an output port. The paper roll carrier is used to hold the label rolls and is replaceably mounted in the receiving compartment. The output port usually has a complete circumferential wall.

[0003] However, when dispensing label stickers, if part of the label sticker is still stuck to the backing paper, improper operation by the user, such as pulling the label sticker horizontally, can cause the backing paper to be pulled out too much. In this case, the perimeter of the dispensing port will form a barrier, which will hinder the removal of the paper roll carrier, making it inconvenient to replace the paper roll carrier and affecting the user experience.

[0004] The above content is only used to assist in understanding the technical solution of the utility model and does not represent an admission that the above content is prior art. Utility Model Content

[0005] In view of the above problems, this utility model proposes a label dispensing machine, which aims to solve the technical problem that the complete peripheral wall of the output port makes it inconvenient to replace the paper roll carrier in the prior art.

[0006] To achieve the above objectives, the label dispenser proposed in this utility model includes:

[0007] The shell has a receiving compartment with an opening on one side, and the front wall of the shell has an output port communicating with the receiving compartment, and the output port extends laterally to communicate with the opening;

[0008] A paper roll carrier is replaceably mounted in the receiving compartment via the opening. The paper roll carrier includes a mounting member, a winding member, and a peeling member. The mounting member is used to rotatably mount the label roll. The winding member is driven to pull the label roll to rotate and wind up the backing paper. The peeling member cooperates with the winding member to change the direction of travel of the backing paper, so that the label sticker is partially or completely peeled off from the backing paper and can be output via the output port.

[0009] A cover that can be detachably fitted over the opening.

[0010] In one embodiment, the take-up member includes a take-up shaft for fixing the free end of the backing paper, and the take-up shaft is located below the peeling member;

[0011] The top wall of the housing has a force-applying notch, at least a portion of the peeling member is exposed in the force-applying notch, and the force-applying notch is connected to the opening and the outlet respectively.

[0012] In one embodiment, the peeling member has a peeling angle that is exposed in the force-applying notch and is located adjacent to or within the output port.

[0013] In one embodiment, the label dispenser further includes a sensor, a main control board, and a driver, wherein the main control board and the driver are disposed within the housing, and the sensor is mounted in the housing and located below the peeling angle;

[0014] The sensor is used to send a stop signal to the main control board when it detects that the label sticker protrudes from the peeling member to a preset position, so that the main control board stops the driving member; and the sensor is also used to send a drive signal to the main control board after it detects that the label sticker is peeled off from the backing paper, so that the main control board drives the driving member.

[0015] In one embodiment, the front wall of the housing has a clearance notch below the peel angle, and the clearance notch communicates with the opening and the outlet respectively.

[0016] In one embodiment, the front wall of the housing is provided with a hand placement space below the peel angle.

[0017] In one embodiment, the paper roll support further includes a front plate disposed below the peeling member, the front plate extending from the top to the bottom of the paper roll support and inclined inward, and the inner wall surface of the front plate being used to support the backing paper.

[0018] In one embodiment, the front wall of the housing has a clearance notch that communicates with both the opening and the outlet.

[0019] The front panel is exposed through the clearance notch.

[0020] In one embodiment, the label dispenser further includes an elastic ejector, which is disposed between the side of the paper roll carrier away from the opening and the housing, so that the elastic ejector acts elastically on the paper roll carrier in the lateral direction, and after the cover is removed, the paper roll carrier is ejected a predetermined distance toward the opening.

[0021] In one embodiment, the label dispenser further includes a drive unit disposed within the housing. The drive unit includes an output shaft, and the output shaft has a connecting portion on the end face of the paper roll carrier in the ejection direction. The wall surface of the take-up shaft opposite to the connecting portion has a mating portion. The connecting portion and the mating portion are axially separable and circumferentially locked together. The peripheral wall of the mating portion is exposed above the connecting portion.

[0022] In one embodiment, the end of the cover is hinged to the front wall of the housing, and the bottom wall of the receiving compartment protrudes from the wall surface facing the opening. The limiting member passes through the mounting member in the pop-out direction and is detachably connected to the cover.

[0023] This novel label dispenser places label rolls on a paper roll support frame, providing stable support and maintaining rotational freedom. The paper roll support frame is removably installed in the receiving compartment via an opening in the housing. When a label roll needs to be replaced, the user simply pulls the paper roll support frame out of the receiving compartment to easily remove the used label roll and replace it with a new one. Because the paper roll support frame is detachable, it significantly improves the convenience and efficiency of the replacement operation compared to existing methods that require direct replacement within the housing. Secondly, the output port extends laterally to connect with the opening, meaning one side of the output port has no sidewall. This prevents the output port from becoming a barrier if the user accidentally pulls out too much backing paper horizontally; the paper roll support frame can still be smoothly removed and replaced, significantly improving the convenience of paper roll replacement and enhancing the user experience.

[0040] This utility model proposes a label dispensing machine 100 for dispensing label stickers 201, which can be peeled off and pasted onto backing paper 202 and wound into label rolls 200.

[0041] In this embodiment of the utility model, please refer to Figures 1 to 9 The label dispenser 100 includes a housing 10, a paper roll carrier 20, and a cover 30. The housing 10 has a receiving compartment 11 with an opening 111 on one side. The front wall 12 of the housing 10 has an output port 121 communicating with the receiving compartment 11, and the output port 121 extends laterally to communicate with the opening 111. The paper roll carrier 20 is replaceably installed in the receiving compartment 11 via the opening 111. The paper roll carrier 20 includes a mounting member 21, a winding member 22, and a peeling member 23. The mounting member 21 is used to rotatably install the label roll 200. The winding member 22 is driven to pull the label roll 200 to rotate and wind up the backing paper 202. The peeling member 23 cooperates with the winding member 22 to change the direction of travel of the backing paper 202, so that the label sticker 201 can be partially or completely peeled off from the backing paper 202 and output via the output port 121. The cover 30 is detachably closed to the opening 111.

[0042] In this embodiment, the label dispenser 100 includes a housing 10, a paper roll carrier 20, and a cover 30. The housing 10 can be rectangular in shape, or it can be designed as curved or other shapes depending on the usage scenario to enhance its aesthetic appeal. The housing 10 can be made of metal or high-strength engineering plastic to ensure strength and durability. The housing 10 has a receiving compartment 11, and one side of the receiving compartment 11 has an opening 111 to allow the user to insert or remove the paper roll carrier 20. An output port 121 is provided on the front wall 12 of the housing 10, which communicates with the receiving compartment 11 and extends laterally to communicate with the opening 111. In this way, when the user needs to replace the label roll 200, even if the backing paper 202 is pulled out too much during operation, the output port 121 will not obstruct the removal of the paper roll carrier 20. The output port 121 can be a strip-shaped opening, with its length extending horizontally. The lateral dimension of the output port 121 can be set according to the width of the label sticker 201, so that the label sticker 201 can pass through smoothly. Furthermore, the edge of the output port 121 can be provided with a guide bevel or rounded corner structure to prevent the label sticker 201 from being scratched during the output process.

[0043] The paper roll carrier 20 is detachably mounted within the receiving compartment 11 via an opening 111. The paper roll carrier 20 includes a mounting member 21, a winding member 22, and a peeling member 23. The mounting member 21 may be a pivot or a support rod for rotatably mounting the label roll 200. In some embodiments, limiting members 14 may be provided at both ends of the mounting member 21 to prevent axial displacement of the label roll 200 during rotation.

[0044] The winding component 22 can be a winding shaft 221, mounted on the paper roll support frame 20. The winding component 22 can be driven by a motor or manually. In the case of motor drive, the motor can be located inside the paper roll support frame 20 or inside the housing 10, and drive the winding component 22 to rotate via the motor's output shaft 61. The winding component 22 is used to pull the backing paper 202, keeping the label roll 200 taut, and winding up the peeled backing paper 202.

[0045] The peeling element 23 can be a peeling bar, a peeling plate, or a guide roller with a certain curvature. The peeling element 23 is installed near the output port 121, positioned at an angle relative to the take-up member 22, to force the backing paper 202 to change its direction of travel. By folding the backing paper 202, the label sticker 201 can be partially or completely separated from the backing paper 202, and the peeled label sticker 201 is fed out along the output port 121. The surface of the peeling element 23 can be made of a low-friction material, such as a metal bar coated with Teflon or a wear-resistant plastic part, to improve peeling smoothness.

[0046] The cover 30 is detachably fitted onto the opening 111 to protect the receiving compartment 11 when the label dispenser 100 is in operation. The cover 30 can be connected to the housing 10 via a snap fastener or magnetic connector. A transparent window can be further provided on the cover 30 to allow the user to observe the remaining amount of the label roll 200.

[0047] This utility model's label dispenser 100 places the label roll 200 on a paper roll support frame 20, providing stable support and maintaining rotational freedom for the label roll 200. The paper roll support frame 20 is removably installed in the receiving compartment 11 through the opening 111 of the housing 10. When it is necessary to replace the label roll 200, the user only needs to pull the paper roll support frame 20 out of the receiving compartment 11 to easily remove the used label roll 200 and replace it with a new one. Since the paper roll support frame 20 is a detachable structure, compared to the existing method of directly replacing the label roll 200 inside the housing 10, the convenience and efficiency of the replacement operation are significantly improved. Secondly, the output port 121 extends laterally to communicate with the opening 111, meaning that one side of the output port 121 has no sidewall. This ensures that even if the user accidentally pulls out too much of the backing paper 202 horizontally, the output port 121 will not form a barrier, and the paper roll support frame 20 can still be smoothly removed and replaced, thus significantly improving the convenience of paper roll replacement and enhancing the user experience.

[0048] In one embodiment, the take-up member 22 includes a take-up shaft 221 for fixing the free end of the backing paper 202, and the take-up shaft 221 is located below the peeling member 23; the top wall of the housing 10 is provided with a force application notch 13, at least a portion of the peeling member 23 is exposed in the force application notch 13, and the force application notch 13 is connected to the opening 111 and the output port 121 respectively.

[0049] In this embodiment, the winding member 22 includes a winding shaft 221, which is used to fix the free end of the backing paper 202. Specifically, during the manufacturing process, when installing the label roll 200, the free end of the backing paper 202 is passed through the peeling member 23 and wound onto the winding shaft 221 to achieve traction and winding of the backing paper 202. As the winding shaft 221 rotates, the backing paper 202 is gradually wound, ensuring smooth peeling of the label roll 200 during operation. Preferably, the winding shaft 221 is located below the peeling member 23 so that the winding shaft 221 exerts a downward pulling force on the backing paper 202, thereby peeling the label sticker 201 off the backing paper 202, and after the label sticker 201 is peeled off, the adhesive side of the label sticker 201 faces downward.

[0050] The top wall of the housing 10 has a force-applying notch 13, through which at least a portion of the peeling member 23 is exposed. On one hand, the user can clearly see the pattern on the label sticker 201 through the force-applying notch 13, preventing the user from taking the wrong sticker. On the other hand, the force-applying notch 13 creates space for the user to apply upward force. When the user takes the label sticker 201, due to the pulling force of the winding member 22 below the peeling member 23, the user grasps the label sticker 201 and applies an upward force, making it easier to peel the label sticker 201 off the backing paper 202, avoiding the backing paper 202 being pulled out due to excessive horizontal pulling force.

[0051] The force-applying notch 13 is connected to the output port 121 and the opening 111 respectively. The shape of the force-applying notch 13 can be square, circular, or other shapes, and is not limited here. In this embodiment, the overall shape of the force-applying notch 13 and the output port 121 can be L-shaped and connected to the opening 111. This provides the user with more operating space when replacing the paper roll carrier 20, making the replacement of the paper roll carrier 20 more convenient.

[0052] In one embodiment, the peeling member 23 has a peeling angle 231 exposed in the force application notch 13, and the peeling angle 231 is disposed adjacent to or within the output port 121.

[0053] In this embodiment, the peeling member 23 has a peeling angle 231, which is located at the end of the peeling member 23 and exposed in the force application notch 13. When the user takes the label sticker 201, they can directly contact the label sticker 201 at the peeling angle 231, thus facilitating quick removal of the label sticker 201. The peeling angle 231 is located near the output port 121 or inside the output port 121. By arranging the peeling angle 231 near or inside the output port 121, after peeling, the front end of the label sticker 201 is always partially attached to the backing paper 202, rather than completely detaching from the backing paper 202 and overlapping the peripheral wall of the output port 121. Therefore, the space below the output port 121 no longer needs to be a fixed supporting structure, thus providing more possibilities for the spatial layout of the housing 10. For example, the front wall 12 can be provided with an exposed notch communicating with the output port 121 to achieve more functions.

[0054] In one embodiment, the label dispenser 100 further includes a sensor 40, a main control board, and a drive unit 60. The main control board and the motor are disposed inside the housing 10. The sensor 40 is installed in the housing 10 and is located below the peeling angle 231. The sensor 40 is used to send a stop signal to the main control board when it detects that the label sticker 201 protrudes from the peeling member 23 to a preset position, so that the main control board stops the drive unit 60. The sensor 40 is also used to send a drive signal to the main control board after it detects that the label sticker 201 is peeled off from the backing paper 202, so that the main control board drives the drive unit 60.

[0055] In this embodiment, the label dispenser 100 is electrically powered. The label dispenser 100 also includes a sensor 40, a main control board, and a drive unit 60. The drive unit 60 may include a motor and its transmission assembly. The motor is connected to the take-up member 22 to provide power to the take-up member 22. The main control board and the motor are both located within the housing 10. The main control board is used to control and coordinate the entire operation of the label dispenser 100. The sensor 40 can be installed on the outside of the front wall 12 of the housing 10 or inside the housing 10. The sensor 40 is located below the peeling angle 231. The sensor 40 can be a photoelectric sensor 40, an infrared sensor 40, or a capacitive sensor 40, used to detect the output state of the label sticker 201. In this embodiment, when the sensor 40 detects that the label sticker 201 protrudes from the peeling member 23 to a preset position, it sends a stop signal to the main control board, causing the main control board to control the motor to stop rotating, thereby preventing the label sticker 201 from being over-dispensed. After the user takes the label sticker 201, the sensor 40 is also used to send a drive signal to the main control board when it detects that the label sticker 201 has been peeled off from the backing paper 202, so that the main control board can drive the motor to rotate again, thereby continuing to pull the backing paper 202 and output the next label sticker 201, thus improving the intelligence of the label dispenser 100.

[0056] In one embodiment, the front wall 12 of the housing 10 has a clearance notch 122 below the peel angle 231, which communicates with both the opening 111 and the outlet 121. This creates a through opening between the outlet 121 and the opening 111, preventing the front wall 12 of the housing 10 from forming a barrier that obstructs the removal of the paper roll carrier 20, as is common in conventional structures. Furthermore, the clearance notch 122, located below the peel angle 231, forms a hand placement space 123, allowing the user to insert their hand into the clearance notch 122, grasp the label sticker 201, and apply upward pressure.

[0057] In one embodiment, a hand placement space 123 is provided below the peeling angle 231 on the front wall 12 of the housing 10. Specifically, the hand placement space 123 may or may not be connected to the opening 111, and its shape and implementation are varied and not limited here. For example, in one example, the front wall 12 of the housing 10 is recessed inward at the position corresponding to the peeling angle 231, thereby forming the hand placement space 123 at the front wall 12; in another example, the peeling angle 231 protrudes from the front wall 12 of the housing 10 along the front-rear direction, and the peeling angle 231 and the peripheral wall of the housing 10 enclose the hand placement space 123; in yet another example, a clearance notch 122 is provided below the peeling member 23 on the housing 10, and the clearance notch 122 is connected to the sticker outlet, thereby forming the hand placement space 123 below the peeling angle 231. Thus, compared to solutions where the peeling member 23 is inside the housing 10 or where no hand placement space 123 is provided below the peeling member 23, this embodiment provides a hand placement space 123 below the peeling angle 231, allowing users to more easily insert their fingers to apply force, further reducing operational difficulties caused by space limitations, and ensuring that users can directly peel off the label sticker 201 with an upward motion.

[0058] In one embodiment, the paper roll support frame 20 further includes a front plate 24, which is disposed below the peeling member 23. The front plate 24 extends from the top of the paper roll support frame 20 to the bottom and is inclined inward. The inner wall surface of the front plate 24 is used to support the liner paper 202.

[0059] In this embodiment, the paper roll carrier 20 also includes a front plate 24, which is located below the peel angle 231 and extends from the top to the bottom of the paper roll carrier 20. The front plate 24 is arranged inclined inward relative to the vertical direction of the paper roll carrier 20. When the liner paper 202 passes the peel angle 231, its path fits precisely against the inner wall surface of the front plate 24. With the inclined support of the front plate 24, the liner paper 202 can be smoothly guided to the winding mechanism, avoiding wrinkles or jamming of the liner paper 202 in a free-hanging state. Secondly, in the event of improper user operation, such as pulling out a large section of the liner paper 202 that has not been completely peeled, the front plate 24 can also guide and separate the liner paper 202 and the label sticker 201 when the winding shaft 221 continues to wind up the liner paper 202. Specifically, when the rewind roller 221 rewinds the liner paper 202, the label sticker 201 is separated from the outer wall of the front plate 24 and cannot enter the paper roll carrier 20 along with the liner paper 202, thus avoiding the problem of the label sticker 201 accumulating or getting stuck in the paper roll carrier 20.

[0060] Furthermore, the outer wall surface of the front panel 24 may be provided with anti-adhesion protrusions, which extend along the length of the front panel 24 to prevent the label sticker 201 from adhering to the front panel 24.

[0061] In one embodiment, the front wall 12 of the housing 10 has a clearance notch 122, which may be rectangular, semi-racetrack shaped, or other shapes. The notch communicates with the opening 111 and the outlet 121, respectively. At least the inclined portion of the front plate 24 is exposed through the clearance notch 122 to prevent the label sticker 201 from directly contacting and adhering to the front wall 12 of the housing 10 during the peeling process. In other words, the exposure of the front plate 24 through the clearance notch 122 allows the label sticker 201 to separate from the outer wall surface of the front plate 24 when being peeled, without remaining on the surface of the front wall 12 of the housing 10 or being wound into the paper roll carrier 20. If the clearance notch 122 is not provided on the front wall 12 of the housing 10, the front plate 24 will be completely hidden inside the housing 10. In this case, the label sticker 201 is likely to come into contact with the inner surface of the front wall 12 of the housing 10 during the peeling process, and may adhere to the front wall 12, resulting in poor output or peeling failure of the label sticker 201.

[0062] In one embodiment, reference is made to Figures 2 to 6 The label dispenser 100 also includes an elastic ejector 70, which is located between the paper roll carrier 20 on the side away from the opening 111 and the housing 10, so that the elastic ejector 70 acts elastically on the paper roll carrier 20 in the lateral direction, and after the cover 30 is removed, the paper roll carrier 20 is ejected from the opening 111 by a preset distance.

[0063] In this embodiment, the elastic ejector 70 can be a compression spring, torsion spring, rubber elastic sheet, or elastic pad, etc., and is not limited thereto. Furthermore, the elastic force of the elastic ejector 70 can be set according to the weight and installation depth of the paper roll support frame 20 to ensure smooth ejection without causing the paper roll support frame 20 to pop out quickly due to excessive ejection force, thus affecting operational safety.

[0064] By providing an elastic ejector 70 between the paper roll carrier 20 and the housing 10, when changing the label roll 200, the user does not need to use tools or forcefully pry off the paper roll carrier 20. Simply removing the cover 30 allows the paper roll carrier 20 to automatically eject a certain distance under the action of the elastic ejector 70, thus providing sufficient operating space for the user. The user can easily remove the paper roll carrier 20 and replace the new label roll 200 by manually pulling it. Furthermore, since there is no baffle between the output port 121 and the opening 111, the paper roll carrier 20 can be easily ejected.

[0065] In one embodiment, the label dispenser 100 further includes a drive member 60, which is disposed inside the housing 10. The drive member includes an output shaft 61, and the output shaft 61 has a connecting portion 611 on its end face in the ejection direction of the paper roll carrier 20. The wall surface of the take-up shaft 221 opposite to the connecting portion 611 has a mating portion 222. The connecting portion 611 and the mating portion 222 are axially separable and are circumferentially locked together. The peripheral wall of the mating portion 222 is exposed on the connecting portion 611.

[0066] In this embodiment, the label dispenser 100 further includes a drive unit 60. The housing 10 may include a surrounding wall 15 and a partition wall 16. The two opposite walls of the partition wall 16 respectively enclose the surrounding wall 15 to form a receiving compartment 11 and an installation compartment. The drive unit 60 may be disposed in the installation compartment, and its output shaft 61 passes through the partition wall 16 to connect with the take-up shaft 221 and provide driving force to the take-up shaft 221. Specifically, the end face of the output shaft 61 in the ejection direction of the paper roll carrier 20 is disposed opposite to the end face of the take-up shaft 221 in the ejection direction, one of which is provided with a connecting part 611 and the other with a mating part 222. The connecting part 611 and the mating part 222 cooperate with each other so that the output shaft 61 can be detachably connected to the take-up shaft 221 in the ejection direction, and ensure a reliable transmission connection between the take-up shaft 221 and the output shaft 61.

[0067] In operation, the drive unit 60 drives the take-up shaft 221 to rotate via the output shaft 61, thereby winding the backing paper 202. When the user needs to replace the paper roll carrier 20, the paper roll carrier 20 pops out towards the opening 111 under the action of the elastic ejector 70, and the take-up shaft 221 also separates from the output shaft 61. Since the output shaft 61 and the take-up shaft 221 are connected by a limiting fit between the connecting part 611 and the mating part 222, the disassembly process is simple and reliable, and quick separation can be achieved without additional operation. After the paper roll carrier 20 is reinstalled into the receiving chamber 11, the mating part 222 on the end face of the take-up shaft 221 can naturally insert into the connecting part 611 on the end face of the output shaft 61, achieving automatic alignment and limiting fit, thereby restoring normal transmission connection.

[0068] Preferably, the connecting part 611 can be a groove, dovetail groove or polygonal slot structure, and the number of grooves can be one, two or more. The mating part 222 can be a pin, a protrusion or a corresponding polygonal plug, and the number of protrusions is set to correspond to the number of grooves to ensure a stable connection and efficient transmission between the winding shaft 221 and the output shaft 61.

[0069] In this embodiment, the output shaft 61 and the take-up shaft 221 are connected by an end-face fit in the ejection direction. Compared with the common peripheral fit structure in the prior art, such as the output shaft 61 having a polygonal cross-section and being inserted into the hole of the take-up shaft 221, where the hole of the take-up shaft 221 has the same cross-sectional shape as the output shaft 61, the end-face fit is structurally simpler and makes it easier to quickly detach when the paper roll carrier 20 needs to be replaced. Specifically, when the user removes the cover 30, the paper roll carrier 20 ejects towards the opening 111 under the action of the elastic ejector 70. Since the output shaft 61 and the take-up shaft 221 only form a limiting fit between the connecting part 611 and the fitting part 222 on the end face, the take-up shaft 221 can smoothly separate from the output shaft 61 without generating large frictional resistance due to large peripheral contact, thereby ensuring that the paper roll carrier 20 can eject smoothly a preset distance. If a circumferential mating structure is adopted, there is a large area of ​​interlocking between the output shaft 61 and the take-up shaft 221. When the paper roll carrier 20 pops out, additional force is often required to disengage the take-up shaft 221 from the output shaft 61. This not only increases the difficulty of replacement operations, but may also cause the paper roll carrier 20 to shake or even be damaged during disassembly and assembly.

[0070] In one embodiment, the end of the cover 30 is hinged to the front wall 12 of the housing 10, and the bottom wall of the receiving compartment 11 is provided with a limiting member 14 protruding from the wall surface of the opening 111. The limiting member 14 passes through the mounting member 21 in the pop-out direction and is detachably connected to the cover 30.

[0071] In this embodiment, the end of the cover 30 is hinged to the front wall 12 of the housing 10, allowing the cover 30 to rotate relative to the housing 10 between an open and closed position. When the user needs to replace the label roll 200, they only need to rotate the cover 30 to the open position to take out or put in the paper roll carrier 20 through the opening 111, thereby improving operational convenience. A limiting member 14 protrudes from the bottom wall of the receiving compartment 11 towards the wall surface of the opening 111. The limiting member 14 passes through the mounting member 21 along the ejection direction of the paper roll carrier 20 and is detachably connected to the cover 30. When the cover 30 is in the closed state, the limiting member 14 can form a stable fit with the cover 30, thereby limiting and fixing the paper roll carrier 20 and preventing the paper roll carrier 20 from loosening due to vibration or external force during operation.

[0072] When the user needs to replace the paper roll carrier 20, first release the limiting member 14 from the housing 10, then rotate the cover 30 to the open position. Under the push of the elastic ejector 70, the paper roll carrier 20 can smoothly pop out a preset distance in the direction of the opening 111, thereby providing the user with sufficient operating space for subsequent removal and replacement.

[0073] In this embodiment, the limiting member 14 can be a protruding post, and a knob is provided at the end of the limiting member 14. The knob protrudes from the cover 30 in a certain direction and is rotated and engaged with the cover 30. In some embodiments, the limiting member 14 and the housing 10 can also be detachably connected by magnetic attraction or threaded connection.
