Abstract

This application discloses a label printer, including a receiving chamber, a roll mounting module, and a cover. The receiving chamber has an opening communicating with its interior cavity and an output port for discharging label stickers. The roll mounting module is replaceably mounted in the receiving chamber through the opening. The roll mounting module includes a positioning member, a winding member, and a deflecting and peeling member. The positioning member is used to rotatably mount the label sticker roll. The winding member is driven to pull the label sticker roll to rotate and wind up the backing paper. The deflecting and 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 through the output port. The cover is used to confine the roll mounting module within the receiving chamber. One end of the cover adjacent to the output port is rotatably connected to the receiving chamber, and the other end is detachably connected to the receiving chamber to open or close the opening. This solves the problem of the cover not closing tightly, ensuring stable output of label stickers.

Description

Technical Field

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

[0002] A label printer is a device that peels off the backing paper from a roll of label stickers and outputs the stickers. It peels off each sticker individually from a wound roll of label stickers for easy user access. Existing label printers typically include: a cover with a sticker outlet, a receiving compartment for housing a roll mounting module, and the roll mounting module itself. The roll mounting module includes a positioning element for positioning the label sticker roll, a winding element for winding the backing paper, and a deflecting element for peeling the label stickers off the backing paper. During use, the backing paper passes the deflecting element and is wound along its underside by the winding element.

[0003] However, in related technologies, when the cover is closed, assembly errors, loose buckles, or stress accumulation due to the cover's own weight or the opening and closing process after long-term use can easily cause the free end near the output port to warp, resulting in an incomplete cover closure. An incomplete cover closure can cause the roll material mounting module in the receiving chamber to shift, causing the peeling mechanism to deviate from the output port, resulting in skewed label output. In severe cases, the label may adhere to the side wall of the receiving chamber, causing a paper jam.

[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 machine, which aims to solve the technical problem that the label machine cover does not close tightly, resulting in skewed sticker output.

[0006] To achieve the above objectives, the label printer proposed in this utility model includes: A receiving compartment having an opening communicating with the interior of the receiving compartment and an output port for dispensing label stickers; A roll mounting module is replaceably mounted in the receiving compartment via the opening. The roll mounting module includes a positioning element, a winding element, and a deflecting and peeling element. The positioning element is used to rotatably mount the label sticker roll. The winding element is driven to pull the label sticker roll to rotate and wind up the backing paper. The deflecting and peeling element cooperates with the winding element to change the direction of travel of the backing paper, so that the label sticker can be partially or completely peeled off from the backing paper and output through the output port. A cover is used to confine the roll mounting module within the receiving chamber. One end of the cover adjacent to the output port is rotatably connected to the receiving chamber, and the other end is detachably connected to the receiving chamber to open or close the opening.

[0007] Furthermore, the labeling machine also includes an elastic ejector, which is disposed between the side of the roll mounting module away from the opening and the receiving chamber, so that the elastic ejector acts elastically on the roll mounting module in the direction toward the opening, and after the cover is removed, the roll mounting module pops out of the opening a preset distance.

[0008] Furthermore, the inner wall of the receiving compartment is provided with a mounting shaft extending in the direction toward the opening; the positioning element includes a mounting cylinder for rotatably fitting the label roll; the mounting cylinder is fitted around the mounting shaft; The cover is detachably connected to the mounting shaft.

[0009] Furthermore, the labeling machine includes a screwing component rotatably connected to the end of the mounting shaft; The cover is provided with a locking part extending along the rotation direction of the screwing member; the thickness of the locking part gradually increases along the preset rotation direction; the screwing member extends out of the cover and locks into the locking part to have a locked position; the screwing member gradually presses the locking part inward along the preset rotation direction; the screwing member can rotate to an unlocked position that is separated from the locking part, and in the unlocked position, the cover can rotate relative to the receiving compartment.

[0010] Furthermore, the cover is provided with a clearance hole, and at least two locking parts are protruding from the inner wall surface of the clearance hole; adjacent locking parts are spaced apart in the circumferential direction of the clearance hole; The locking portion has a thin-walled region and a thick-walled region that are connected to each other; wherein the thin-walled region of one locking portion is adjacent to the thick-walled region of an adjacent locking portion; The screwing component has a tightening portion located on the outside of the cover body. The tightening portion is pressed against the outside of the locking portion, and the tightening portion can be rotated to disengage from between two adjacent locking portions, so as to separate the cover body from the mounting shaft.

[0011] In one embodiment, the receiving compartment includes a compartment body and a connector fixedly connected to the compartment body; the roll mounting module is replaceably mounted in the compartment body via the opening; the wall thickness of the connector is greater than the wall thickness of the compartment body; and the cover is rotatably connected to the connector.

[0012] Furthermore, the labeling machine also includes a sensor for detecting the position where the label sticker is peeled off from the backing paper, with a portion of the sensor penetrating the wall of the chamber and connected to the connector.

[0013] In one embodiment, the labeling machine further includes a plurality of elastic ejector members, wherein a portion of the elastic ejector members are positioned corresponding to or adjacent to the winding member, and another portion of the elastic ejector members are positioned corresponding to or adjacent to the positioning member.

[0014] In one embodiment, the labeling machine further includes a driving component disposed within the receiving chamber; the driving component includes an output shaft, and the output shaft has a connecting portion on the end face of the roll mounting module in the ejection direction; The wall surface opposite the connecting part of the winding member is provided with a mating part.

[0015] In one embodiment, the receiving chamber has an output port on its side wall and a force application window communicating with the output port on its top wall; the steering stripper is exposed in the force application window at least in the portion adjacent to the output port.

[0016] Furthermore, the output port and the force application window extend toward the cover to penetrate the receiving compartment; when the cover closes the opening, the cover blocks the edges of the output port and the force application window.

[0017] Furthermore, the side wall of the receiving compartment is provided with a hand placement space below the steering stripper.

[0018] This utility model label machine uses a roll-mounting module that can be interchangeably installed in the receiving chamber through the opening, allowing the roll-mounting module to be quickly removed and reinstalled in the receiving chamber, facilitating the replacement and maintenance of label rolls. Simultaneously, by rotatably connecting one end of the cover near the output port to the receiving chamber and detachably connecting the other end, the roll-mounting module is confined within the receiving chamber, solving the problem of the cover near the output port easily warping and causing incomplete sealing. This ensures the roll-mounting module is stably installed in the receiving chamber, preventing its turning and peeling parts from deviating from the output port, guaranteeing the correct label output, and thus making the label output more stable.

[0026] This utility model proposes a labeling machine.

[0027] In this embodiment of the utility model, please refer to Figures 1 to 9 The label sticker 11 is peelably adhered to the backing paper 12 and wound into a label sticker roll 10. The label machine 100 includes a receiving chamber 20, a roll mounting module 30, and a cover 40. The receiving chamber 20 has an opening 21 communicating with the inner cavity of the receiving chamber 20 and an output port 22 for outputting the label sticker 11. The roll mounting module 30 is replaceably mounted in the receiving chamber 20 through the opening 21. The roll mounting module 30 includes a positioning member 31, a winding member 32, and a deflecting peeling member 33. The positioning member 31 is used for rotatably mounting the label sticker 11. The unit includes a label roll 10; a rewinding member 32 driven to pull the label roll 10 to rotate and rewind the backing paper 12; a deflecting peeling member 33 cooperating with the rewinding member 32 to change the direction of travel of the backing paper 12, so that the label 11 is peeled off from the backing paper 12 and output through the output port 22; and a cover 40 for confining the roll assembly within the receiving chamber, with one end of the cover 40 adjacent to the output port 22 rotatably connected to the receiving chamber 20 and the other end detachably connected to the receiving chamber 20 to open or close the opening 21.

[0028] In this embodiment, the receiving chamber 20 provides installation space for the roll mounting module 30 and the label sticker roll 10. The receiving chamber 20 has an outward-facing opening 21, which makes it easier to install and remove the roll mounting module 30 and replace the label sticker roll 10; at the same time, the output port 22 allows the label sticker 11 to be easily peeled off and output.

[0029] The roll mounting module 30 is a key component for peeling and conveying the label sticker 11 and winding the backing paper 12. It can be understood that it can be replaced and mounted in the receiving chamber 20, either as a whole or in part, via the opening 21, to facilitate the replacement and adjustment of the label sticker roll 10. The roll mounting module 30 can be detachably connected, allowing it to be quickly removed and reinstalled into the receiving chamber 20, facilitating the replacement and maintenance of the label sticker roll. Detachability can be achieved through methods such as plug-in snap-fit, sliding rail limiting, slot-protrusion engagement, or socketing.

[0030] The roll mounting module 30 includes a positioning element 31, a winding element 32, and a deflecting and peeling element 33. The positioning element 31 rotatably mounts the label roll 10 onto itself, allowing it to rotate smoothly during output. Essentially, one end of the label roll 10 is fixedly connected to the positioning element 31, allowing it to gradually rotate and release as needed. The winding element 32 drives the tensioning and winding of the backing paper 12 via a drive (such as a motor or mechanical transmission device), thus collecting the used backing paper 12. The deflecting and peeling element 33 changes the direction of travel of the backing paper 12, causing the label 11 to separate from the backing paper 12 at the bending point and be output smoothly. This structure ensures stable label peeling position and improves peeling efficiency.

[0031] The cover 40 serves to confine the roll installation module 30, label sticker roll 10, etc., within the receiving chamber 20, so that the label machine 100 can effectively protect the internal structure when not in use, and seal the receiving chamber 20 to prevent external dust and dirt from entering.

[0032] One end of the cover 40 adjacent to the outlet 22 is rotatably connected to the receiving chamber 20, making this end a stable pivot point. This ensures that the cover 40 has a defined force axis during opening and closing, preventing random misalignment. Structurally, this ensures the cover 40 falls precisely into the preset position when closed, preventing issues like the end near the outlet 22 being suspended or warped. The end of the cover 40 adjacent to the outlet 22 can be rotatably connected to the receiving chamber 20 via a pivot or hinge; this is not limited here. It can be understood that the cover 40 can be directly or indirectly rotatably connected to the receiving chamber 20.

[0033] Meanwhile, the rotating end of the cover 40 (the end adjacent to the output port 22) serves as a fixed fulcrum, allowing the cover 40 to be easily disassembled and reassembled by simply connecting and disconnecting the free end (the end furthest from the output port 22) during opening and closing operations. This simplifies the user's operation, reduces effort, and prevents the cover 40 from detaching or falling apart. Therefore, compared to traditional multi-point snap-fit ​​or completely separable cover 40 structures, the rotating section design in this invention significantly improves the quick-release performance and ease of operation of the cover 40.

[0034] The end of the cover 40 furthest from the outlet 22 is detachably connected to the receiving compartment 20. By using a snap, magnet, slot, or other detachable structure, the free end of the cover 40 is firmly fixed when closed. This not only overcomes the "half-closed" or loosening caused by relying solely on gravity for closure, but also maintains sufficient clamping or adsorption force after long-term use, thus effectively preventing the cover 40 from tilting outward.

[0035] One end of the cover 40 adjacent to the outlet 22 is rotatably connected to the receiving chamber 20, while the other end is detachably connected to the receiving chamber 20. Thus, the two ends work together to improve the reliability and stability of the cover 40 closing the opening 21. Specifically, the rotating end ensures the direction of movement and positioning accuracy, while the free end ensures the closing strength and holding effect. The combination of these two aspects creates a dual constraint mode of "hinged fixation + end locking" for the entire cover 40 in the closed state. Compared to the traditional method of only single-sided snap-fit ​​connection, the cover 40 fits the receiving chamber 20 more smoothly and tightly, solving the problem of easy warping near the outlet 22.

[0036] The label machine 100 of this utility model is replaceably installed in the receiving chamber through the opening via a roll mounting module 30, which allows the roll mounting module 30 to be quickly removed and reinstalled in the receiving chamber 20, facilitating the replacement and maintenance of the label roll 10. At the same time, by rotatably connecting one end of the cover 40 near the output port 22 to the receiving chamber 20 and detachably connecting the other end to the receiving chamber 20, the roll mounting module 30 is confined within the receiving chamber 20, solving the problem of the cover 40 near the output port 22 easily warping and causing incomplete sealing. This ensures that the roll mounting module 30 is stably installed in the receiving chamber 20, preventing its turning and peeling parts 33 from deviating from the output port, ensuring the label 11 is output in the correct position, and thus making the output of the label 11 more stable.

[0037] The receiving compartment 20 provides installation space and realizes the fixing, pulling and peeling output of the label sticker roll 10 and the storage of the backing paper 12 through the roll installation module 30, so that the sticker output is smooth; and the rotational connection with the cover 40 realizes the quick opening and closing operation of the cover 40, which improves the convenience of replacing the label sticker roll 10.

[0038] Furthermore, referring to Figure 2 and Figure 3 The labeling machine 100 also includes an elastic ejector 50, which is located between the roll mounting module 30 on the side away from the opening 21 and the receiving chamber 20, so that the elastic ejector 50 elastically acts on the roll mounting module 30 in the direction toward the opening 21, and after the cover 40 is removed, the roll mounting module 30 pops out of the opening 21 by a preset distance.

[0039] The elastic ejector 50 is used to eject the roll mounting module 30, avoiding the need for the user to invert the opening to remove the roll mounting module 30 from the receiving chamber 20, thus avoiding the risk of damage to the label roll or equipment caused by inverting the opening. Specifically, when the cover 40 is closed, the elastic ejector 50 is in a compressed state; when the cover 40 is opened, the elastic ejector 50 restores its deformation and generates elastic force, pushing the roll mounting module 30 towards the opening 21 and protruding out of the receiving chamber 20.

[0040] The elastic ejector 50 can be an elastic element in the form of a spring, leaf spring, elastic pad, or elastic block (such as a rubber block), or it can be a combination of the above elastic elements and other structural components. The specific installation method of the elastic ejector 50 is not limited in detail here, as long as it can achieve the elastic ejection function of the coil mounting module 30. For example, one end of the elastic ejector 50 is confined to the fixed structure of the receiving chamber 20, and the other end freely abuts against the coil mounting module 30. Specifically, such as... Figure 2 and Figure 3 As shown, the receiving chamber 20 also includes a partition plate 81 disposed within the cavity, dividing the receiving chamber 20 into a first chamber for accommodating the roll mounting module 30 and a second chamber for accommodating a portion of the drive unit 70. An elastic ejector 50, capable of reciprocating between the first and second chambers, is inserted into the partition plate 81. One end of the elastic ejector 50 located in the first chamber abuts against the roll mounting module 30.

[0041] In one embodiment, reference is made to Figure 2 and Figure 4 The inner wall of the receiving compartment 20 is provided with a mounting shaft 23 extending in the direction toward the opening 21; the positioning member 31 includes a mounting cylinder 311 for rotatably fitting the label roll 10; the mounting cylinder 311 is fitted around the mounting shaft 23; the cover 40 is detachably connected to the mounting shaft 23.

[0042] In this embodiment, the mounting shaft 23 extends along the direction toward the opening 21 and is disposed on the inner wall surface of the receiving chamber 20, providing guidance and support for the mounting cylinder 311 (roll mounting module 30). The label roll 10 is rotatably mounted on the outer wall of the mounting cylinder 311, which serves as the rotation center of the label roll.

[0043] Both the cover 40 and the mounting cylinder 311 are installed based on the same mounting shaft 23, meaning they share a common mounting reference, thus avoiding offset problems caused by different mounting references. Furthermore, the cover 40 is detachably connected to the mounting shaft to secure the cover 40 to the receiving chamber 20, while simultaneously and stably confining the coil mounting module 30 within the receiving chamber 20.

[0044] The cover 40 is detachably connected to the mounting shaft 23. This detachable connection can be achieved through plug-in snap-fit, slide rail limit, slot-boob engagement, sleeve connection, etc.

[0045] Furthermore, referring to Figure 1 , Figure 2 , Figure 8 as well as Figure 9The label printer 100 includes a screwing member 232 rotatably connected to the end of the mounting shaft 23; a locking part 41 extending along the rotation direction of the screwing member 232 is provided on the cover 40; the thickness of the locking part 41 gradually increases along a preset rotation direction; the screwing member 232 extends out of the cover 40 and locks into the locking part 41 to have a locked position; the screwing member 232 gradually presses the locking part 41 inward along the preset rotation direction; the screwing member 232 can rotate to an unlocked position separated from the locking part 41, in which the cover 40 can rotate relative to the receiving chamber 20.

[0046] In this embodiment, the screw-on component 232 is rotatably connected to the end of the mounting shaft 23. In one example, the screw-on component 232 is axially limited by a snap-fit ​​with the mounting shaft 23 and has circumferential rotational freedom. By the user screwing it in a preset direction, the screw-on component 232 locks or releases from the locking part 41 on the cover 40, thereby determining whether the cover 40 is in a locked state. At different rotation angles, different clamping forces can be applied to the cover 40 to achieve gradual locking or releasing. The screw-on component 232 can be disc-shaped, winged, nut-shaped, etc.

[0047] The locking part 41 extends along a preset rotation direction, and its thickness gradually increases along this direction. When the screwing member 232 rotates, due to the change in thickness of the locking part 41, the screwing member 232 gradually comes into contact with its contact surface, so that the whole reaches a "from loose to tight" locking state and is stably maintained in the locked position. In this way, the cover 40 is reliably and stably closed; and the opening and closing operation is simplified by switching between the locked and unlocked positions through the action of the screwing member 232. The locking part 41 can be an arc-shaped gradually thickened structure (similar to a beveled ring), a trapezoidal step type, a spiral surface with a taper, etc.

[0048] Furthermore, the cover 40 is provided with a clearance hole 42, and at least two locking portions 41 are respectively provided on the inner wall surfaces of the clearance hole 42 that are arranged opposite to each other along its radial direction; two adjacent locking portions 41 are spaced apart in the circumferential direction of the clearance hole 42; the locking portions 41 have thin-walled areas and thick-walled areas that are connected to each other; the thin-walled area of ​​one locking portion 41 is adjacent to the thick-walled area of ​​the adjacent locking portion 41; the screwing member 232 has a tightening portion located on the outside of the cover, the tightening portion is correspondingly pressed against the outside of the locking portion 41, and the tightening portion can be rotated to disengage from the two adjacent locking portions, so that the cover 40 is separated from the mounting shaft 23.

[0049] In this embodiment, a clearance hole 42 is provided on the cover 40, providing a through-hole path for the installation of the screw-on component 232. The screw-on component 232 extends out of the receiving chamber 20 from the clearance hole 42 for the user to hold and operate. The two locking parts 41 are locked on both sides of the free end of the cover 40, avoiding the risk of tilting of the free end of the cover 40 due to unilateral force.

[0050] In this embodiment, two locking parts 41 are provided at the free end of the cover 40 and simultaneously locked to the screwing part 232, so that the free end of the cover 40 forms a double-point positioning constraint when closed, making the cover 40 subject to uniform force and a reliable seal. At the same time, the double locking parts 41 can distribute the force and wear, enhancing the durability of the cover 40 under long-term and frequent use conditions, and achieving better sealing performance and reliability.

[0051] The tightening part is designed for user hand operation. The tightening part of the screw-on component 232 is designed in a form that is easy for the hand to grip, such as a cylinder or wing with anti-slip texture, to improve the feel and stability during operation.

[0052] In one embodiment, reference is made to Figure 2 The receiving compartment 20 includes a compartment body and a connector 26 fixedly connected to the compartment body; the roll material mounting module 30 is replaceably installed in the compartment body 20 through the opening; the wall thickness of the connector 26 is greater than the wall thickness of the compartment body; the cover 40 is rotatably connected to the connector 26.

[0053] Compared to the wall structure where the cover 40 is rotatably connected to the compartment body, this embodiment adds a connector 26 with a larger wall thickness, giving the cover a more stable rotating base. This reduces the impact of compartment body deformation on the opening and closing accuracy of the cover 40, thus ensuring that the cover 40 is stably rotatably connected to the compartment body. The connector can be fixedly connected to the compartment body by screws, inserts, or slot-and-buckle joints.

[0054] Furthermore, referring to Figure 1 The labeling machine 100 also includes a sensor 60 for detecting the position where the label sticker 11 is peeled off from the backing paper, and part of the sensor 60 passes through the wall of the chamber and is connected to the connector 26.

[0055] In this embodiment, the sensor 60 is used to detect the position and state of the label sticker 11 on the output path. For example, it can detect the position and gap of the front edge of the label to determine the peeling position of each label, which facilitates control of the subsequent peeling process. The sensing method can be a photoelectric sensor, a capacitive sensor, or an infrared sensor, etc., providing non-contact or contact detection according to different needs. The sensor 60 can be located beside or below the output path (i.e., the area through which the label sticker 11 and the backing paper 12 pass) to accurately identify the position of the label sticker 11.

[0056] When the sensor 60 detects that the label sticker 11 protrudes from the preset position of the turning peeler 33, it sends a stop signal to the main control board to stop the motor. The sensor 60 is also used to detect that after the label sticker 11 is peeled off from the backing paper 12, it sends a drive signal to the main control board to drive the motor.

[0057] Because connector 26 has a relatively large wall thickness, it provides a more stable mounting base for sensor 60. Part of sensor 60 penetrates the wall of receiving compartment 20 and is connected to connector 26. This not only enhances the installation stability of sensor 60 but also avoids occupying too much internal space. The connection between sensor 60 and connector 26 can be detachable or non-detachable, such as snap-fit, plug-in, screw-in, riveting, etc.

[0058] In this embodiment, by reusing the connector 26, the connector 26 serves as both the rotational support for the cover 40 and the mounting base for the sensor 60, effectively improving the stability and compactness of the overall structure.

[0059] In one embodiment, reference is made to Figure 2 and Figure 3 The label printer 100 also includes multiple elastic ejector parts 50, some of which are positioned to correspond to or be close to the winding part 32, and others are positioned to correspond to or be close to the positioning part 31.

[0060] If a single elastic ejector 50 is only provided in a certain part of the receiving chamber 20 (such as the rear end of the positioning member 31), the elastic force application point will be too concentrated, and the coil installation module 30 will easily tilt or jam. In this embodiment, elastic ejectors 50 are provided on both the winding member 32 and the positioning member 31, which can form two or more points of joint force, maintain balance during pushing, and thus achieve uniform movement of the entire mounting frame. In one example, since the weight of the coil installed on the positioning member 31 is large, the ejection force requirement is large. Therefore, the number of elastic ejectors 50 provided at the position of the positioning member 31 is greater than the number of elastic ejectors 50 provided at the position of the winding member 32, so as to meet the different elastic force requirements of different areas.

[0061] In one embodiment, the labeling machine 100 further includes a drive unit 70 disposed in the receiving chamber 20; the drive unit 70 includes an output shaft 71, and the output shaft 71 has a connecting portion 711 on the end face of the roll mounting module 30 in the ejection direction; The wall surface opposite to the connecting part 711 of the winding member 32 is provided with a mating part 321. The connecting part 711 and the mating part 321 can be separated and connected in the axial direction, and are mated in the circumferential direction. The circumferential wall of the mating part 321 is exposed in the connecting part 711 to facilitate the axial separation of the winding member 32 and the output shaft 71.

[0062] In operation, the drive unit 70 drives the take-up member 32 to rotate via the output shaft 71, thereby winding the backing paper 12. When the user needs to replace the roll mounting module 30, the roll mounting module 30 pops out towards the opening 21 under the action of the elastic ejector 50, and the take-up member 32 also separates from the output shaft 71. Since the output shaft 71 and the take-up member 32 are connected by a limiting fit between the connecting part 711 and the mating part 321, the disassembly process is simple and reliable, and quick separation can be achieved without additional operation. After the roll mounting module 30 is reinstalled into the receiving chamber 20, the mating part 321 on the end face of the take-up member 32 can naturally insert into the connecting part 711 on the end face of the output shaft 71, achieving automatic alignment and limiting fit, thereby restoring normal transmission connection.

[0063] Compared to the common peripheral surface mating structure in the prior art, such as the output shaft 71 having a polygonal cross-section and being inserted into the insertion hole of the take-up member 32, the output shaft 71 and the take-up member 32 in this embodiment adopt a method of mating with opposite end faces in the ejection direction, which is more structurally simpler and makes it easier to quickly detach when the roll mounting module 30 needs to be replaced.

[0064] If a circumferential mating structure is adopted, there is a large area of ​​interlocking between the output shaft 71 and the take-up piece 32. When the roll mounting module 30 is ejected, additional force is often required to disengage the take-up piece 32 from the output shaft 71. This not only increases the difficulty of replacement operations, but may also cause the roll mounting module 30 to shake or even be damaged during disassembly and assembly.

[0065] In this embodiment, when the user removes the cover 40, the roll mounting module 30 pops out towards the opening 21 under the action of the elastic ejector 50. Since the output shaft 71 and the take-up member 32 only form a limiting fit between the connecting part 711 and the mating part 321 on the end face, the take-up member 32 can smoothly separate from the output shaft 71 without generating large frictional resistance due to the large area of ​​contact on the circumferential surface, thereby ensuring that the roll mounting module 30 can pop out smoothly at a preset distance.

[0066] The connecting part 711 can be a groove, dovetail groove or polygonal slot structure. The number of grooves can be one, two or more. The mating part 321 can be a pin, a protrusion or a corresponding polygonal connector. The number of protrusions is set to correspond to the number of grooves to ensure a stable connection and efficient transmission between the winding part 32 and the output shaft 71.

[0067] In one example, the label printer 100 also includes a drive unit 70 and a mounting chamber. The mounting chamber and the receiving chamber 20 are separated by a partition wall. The drive unit 70 can be disposed within the mounting chamber, and its output shaft 71 passes through the partition wall to connect with the take-up member 32 and provide driving force to the take-up member 32. Specifically, the end face of the output shaft 71 in the ejection direction of the roll mounting module 30 is opposite to the end face of the take-up member 32 in the ejection direction. One of them has a connecting part 711, and the other has a mating part 321. The connecting part 711 and the mating part 321 cooperate with each other so that the output shaft 71 can be detachably connected to the take-up member 32 in the ejection direction, and a reliable transmission connection between the take-up member 32 and the output shaft 71 is ensured.

[0068] In one embodiment, the side wall of the receiving chamber 20 is provided with an outlet 22, and the top wall of the receiving chamber 20 is provided with a force application window 24 communicating with the outlet 22; at least a portion of the steering stripper adjacent to the outlet 22 is exposed in the force application window 24.

[0069] In this embodiment, a force-applying window 24 is provided on the top wall of the receiving compartment 20, which connects to the output port 22. The shape of the force-applying window 24 can be square, circular, or other shapes, and is not limited here. In this embodiment, the overall shape of the force-applying window 24 and the output port 22 can be L-shaped. The deflecting peeling member is exposed inside the force-applying window 24, thereby forming a force-applying space between the output port 22 and the force-applying window 24. In other words, the force-applying space is the space above the force-applying window 24. When the user takes the label sticker 11, due to the pulling force of the winding member 32 below the deflecting peeling member, the user grasps the label sticker 11 and applies an upward force, making it easier to peel the label sticker 11 off the backing paper 12, avoiding the backing paper 12 being pulled out additionally due to excessive horizontal pulling force. The force-applying window 24 and the output port 22 form a continuous paper output space, allowing the user to directly tear or pick up the label sticker 11 from above, which is convenient.

[0070] By positioning the rewinding component 32 below the peeling component and providing a force application window 24 on the top wall of the receiving chamber 20, the label machine 100 allows the user to apply an upward force to the label sticker 11 after it has been peeled off by the peeling component. Due to the downward pulling force of the rewinding component 32 on the backing paper 12 below the peeling component, the label sticker 11 is more easily peeled off from the backing paper 12, avoiding the problem in the prior art where the user can only pull the label horizontally forward. This ensures that the backing paper 12 remains in the normal winding path and is not excessively pulled out, thereby effectively preventing the backing paper 12 from being excessively pulled and causing the unpeeled label to move with the backing paper 12, thus improving the user experience.

[0071] In one embodiment, reference is made to Figure 1 and Figure 2The outlet 22 and the force application window 24 extend toward the cover 40 to penetrate the receiving chamber 20; when the cover 40 closes the opening 21, the cover 40 blocks the edges of the outlet 22 and the force application window 24.

[0072] 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 removal of the roll installation module 30 will not be hindered by the baffles of the output port 22 and the force application window 24. The output port 22 can be a strip-shaped opening 21, extending horizontally along its length. The lateral dimension of the output port 22 can be set according to the width of the label sticker 11, allowing the label sticker 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 sticker 11 from being scratched during output.

[0073] Furthermore, referring to Figure 5 The side wall of the receiving compartment 20 is provided with a hand placement space 25 below the steering stripping component 33.

[0074] In this embodiment, the hand placement space 25 may or may not be connected to the opening 21, and its shape and implementation are varied and not limited here. For example, in one example, the front wall of the receiving chamber 20 is recessed inward at the position corresponding to the position of the directional peeling member 33, thereby forming the hand placement space 25 at the front wall. Thus, compared to the solution where the peeling member is inside the receiving chamber 20, or where no hand placement space 25 is provided below the peeling member, this embodiment, by providing the hand placement space 25 below the directional peeling member 33, allows the user to more easily insert their fingers to apply force, further reducing the operational difficulties caused by space constraints, and ensuring that the user can directly peel off the label sticker 11 with an upward movement.

[0075] 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.
