Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically to a linkage shearing structure and a printer. Background Technology

[0002] In the field of thermal transfer printers, the coordinated cutting and resetting of the cutter and cutter button is a crucial aspect of ensuring the printer's normal operation. In existing technologies, the cutting linkage mechanism often employs a rotating linkage mechanism, which uses the rotation of the linkage to achieve the cutting action of the cutter, while the cutter's resetting is accomplished by a torsion spring connected to the cutter head.

[0003] Existing shearing linkage methods using rotating linkage mechanisms have significant drawbacks. Due to the motion characteristics of rotating linkage mechanisms, sufficient space is required inside the printer to accommodate the rotation trajectory of the linkage. This also limits the internal space layout of the printer. When the internal space is insufficient, the rotating linkage mechanism may be unable to complete the rotation path, leading to interruption or failure of the shearing action, thus affecting the normal use and reliability of the printer. Utility Model Content

[0004] Therefore, this utility model aims to solve the problem that the cutting mechanism of portable printers such as thermal transfer printers or thermal printers in the prior art requires a large space for the rotating linkage mechanism, which easily leads to unsmooth cutting action, and thus provides a linkage cutting structure and printer.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: A linkage shearing structure, comprising: Fasteners; The movable component is disposed on the fixed member and is capable of reciprocating along the first direction (X); A shearing assembly includes a fixed shearing member and a movable shearing member that can be opened and closed for shearing. The fixed shearing member is connected to the fixed member, and the movable shearing member is connected to the movable assembly. The movable assembly is adapted to drive the movable shearing member to reciprocate so that the movable shearing member and the fixed shearing member switch between a closed state and an open state. An elastic element connects the fixed element and the movable component; In this configuration, the movable shearing member and the fixed shearing member are in a closed state, and the elastic member stores energy and has a tendency to drive the movable component and cause the movable component to drive the movable shearing member to switch to an open state.

[0006] Furthermore, the activity components include: A sliding member is disposed on the fixed member, which can reciprocate along a first direction (X); A button is provided to drive the slider to move back and forth.

[0007] Furthermore, the button is rotatably connected to the fixing member, and the button is provided with a push block that abuts against the sliding member.

[0008] Furthermore, the button is located at the first end of the slider, and a guide post is provided on the second end sidewall of the slider. The movable shearing member is connected to the guide post, and the guide post is adapted to drive the movable shearing member to reciprocate.

[0009] Furthermore, the first end of the movable shearing member is adapted to shear with the fixed shearing member, the second end of the movable shearing member is connected to the guide post, and the guide post is adapted to drive the movable shearing member to reciprocate and translate.

[0010] Furthermore, the movable shearing component is provided with a strip-shaped limiting groove, and the guide post is disposed in the strip-shaped limiting groove and is adapted to drive the movable shearing component to reciprocate.

[0011] Furthermore, the elastic element is a return spring, with a first end connected to the fixed element and a second end connected to the sliding element, and the movable component is adapted to reciprocate along the extension and retraction direction of the return spring.

[0012] Furthermore, a limiting baffle is provided on one side of the fixing member, the movable component is movably disposed between the fixing member and the limiting baffle, and the movable shearing member is disposed on the side of the limiting baffle away from the fixing member.

[0013] Furthermore, the first and second ends of the movable shearing member are bent, and there is an angle of less than or equal to 90° between the first and second ends of the movable shearing member. The middle part of the movable shearing member is rotatably connected to the limiting baffle by a rivet.

[0014] A printer comprising any of the above-described linkage shearing structures.

[0015] The technical solution of this utility model has the following advantages: 1. The linkage shearing structure provided by this utility model, when the movable component moves along the first direction (X), causes the elastic element to stretch and store energy. At this time, the movable shearing component and the fixed shearing component turn to a closed state. When the movable component is released, the elastic element releases energy and retracts to its initial position under its own stress, while simultaneously driving the movable component to move to its initial position. At this time, the movable shearing component and the fixed shearing component turn to an open state. This method of stretching and storing energy through the elastic element and releasing and retracting to reset drives the movable component to reciprocate and translate, thereby driving the movable shearing component to reciprocate and achieve the opening and closing shearing of the shearing component. This linkage drive structure achieves stable shearing action of the shearing component on the consumables through horizontal movement, and achieves rapid and accurate reset through the retraction of the elastic element, realizing the effect of efficient shearing and reset action of the shearing structure within the limited space of the printer. At the same time, the movable component, as the driving structure, greatly reduces the space required for movement compared with the rotating linkage mechanism in the prior art, and the elastic element only needs to extend and retract, so there will be no jamming phenomenon when resetting, which can ensure the stable translation of the movable component, thereby maintaining the shearing stability of the shearing component.

[0016] 2. The linkage shearing structure provided by this utility model has a button rotatably connected to a fixed component, and the button is provided with a push block that abuts against the sliding component. With this configuration, simply pressing the button to rotate it will cause the push block against the sliding component to drive the sliding component to move horizontally, without the button needing to move with it. This reduces the space occupied by the button and further reduces the space required for the shearing structure to occupy in the printer's movement space.

[0017] 3. The linkage shearing structure provided by this utility model has a strip-shaped limiting groove on the movable shearing component, and a guide post is disposed in the strip-shaped limiting groove and adapted to drive the movable shearing component to reciprocate. This arrangement, through the cooperation of the strip-shaped limiting groove and the guide post, limits the movement path of the movable shearing component, enabling the movable shearing component to reciprocate stably and achieving stable opening and closing shearing of the shearing assembly.

[0018] 4. The linkage shearing structure provided by this utility model has the following configuration: In the initial state, the first end of the sliding member is close to the first end of the return spring; in the stretched state, the first end of the sliding member moves toward the second end of the return spring. With this configuration, when the button is pressed and the sliding member is pushed to move away from the button, the second end of the return spring moves away from the first end of the return spring to stretch; when the pushing force on the sliding member is released, under its own stress, the second end of the return spring quickly moves toward the first end of the return spring to return to the initial state, simultaneously causing the sliding member to quickly move toward the button to reset. The movement response is fast and smooth, and there is no jamming during the translation process, effectively ensuring the normal operation of the printer.

[0019] 5. The linkage shearing structure provided by this utility model has a limiting baffle on one side of the fixed component, a movable component movably disposed between the fixed component and the limiting baffle, and a movable shearing component disposed on the side of the limiting baffle away from the fixed component. This arrangement allows the limiting baffle to limit the movement of the movable component, ensuring its stability and thus maintaining the stability of the movable shearing component during its shearing motion. Simultaneously, the limiting baffle separates the movable component and the movable shearing component, preventing mutual interference when they move simultaneously. Attached Figure Description

[0022] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] In the description of this utility model, it should be noted that the term "end" refers to a section of structure with a certain length, and does not simply indicate a single point. The terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] like Figures 1-6 The illustrated linkage shearing structure includes a fixed member 1, a movable component 3 movably connected to the fixed member 1 via an elastic member 2, and a shearing component 4 connecting the fixed member 1 and the movable component 3. The movable component 3 is disposed on the fixed member 1 and can reciprocate along a first direction (X). The shearing component 4 includes a fixed shearing member 41 and a movable shearing member 42 that can be opened and closed for shearing. The fixed shearing member 41 is connected to the fixed member 1, and the movable shearing member 42 is connected to the movable component 3. The movable component 3 is adapted to drive the movable shearing member 42 to reciprocate so that the movable shearing member 42 and the fixed shearing member 41 can switch between a closed state and an open state. The elastic member 2 is connected between the fixed member 1 and the movable component 3. When the movable shearing member 42 and the fixed shearing member 41 are in the closed state, the elastic member 2 stores energy and has the tendency to drive the movable component 3, so that the movable component 3 drives the movable shearing member 42 to switch to the open state.

[0027] This linkage shearing structure, by pushing the movable component 3 to move along the first direction (X), causes the elastic element 2 to stretch and store energy. At this time, the movable shearing element 42 and the fixed shearing element 41 turn to a closed state. When the movable component 3 is released, the elastic element 2 releases energy and retracts to its initial position under its own stress, simultaneously driving the movable component 3 to move to its initial position. At this time, the movable shearing element 42 and the fixed shearing element 41 turn to an open state. This method of stretching and storing energy through the elastic element 2 and releasing and retracting to reset drives the movable component 3 to reciprocate translation, thereby driving the movable shearing element 42 to reciprocate to achieve shearing. The opening and closing of the cutting component 4 is a linkage drive structure. This structure achieves stable cutting of consumables by the cutting component 4 through horizontal movement, and quick and accurate reset through the retraction of the elastic element 2. This achieves efficient cutting and reset within the limited space of the printer. At the same time, the translational movable component 3 serves as the drive structure, which greatly reduces the required space compared to the rotating linkage mechanism in the prior art. Moreover, the elastic element 2 only needs to extend and retract, and there will be no jamming during reset. This ensures the stable translation of the movable component 3, thereby maintaining the stable cutting of the cutting component 4.

[0028] In this embodiment, as Figures 3-5 As shown, the movable component 3 includes a slider 33 movably connected to the elastic member 2 and a button 31 adapted to drive the slider 33. The button 31 is connected to the slider 33 and is adapted to drive the slider 33 to reciprocate. Specifically, the button 31 is rotatably connected to the fixed member 1, and the button 31 is provided with a push block 32 that abuts against the slider 33. With this configuration, simply pressing the button 31 to rotate it will cause the push block 32 abutting against the slider 33 to drive the slider 33 to translate. The button 31 does not need to translate along with it, reducing the space occupied by the button 31 and further reducing the movable space of the printer required by the shearing structure.

[0029] In this embodiment, as Figure 3 , 4 As shown in Figures 6 and 7, button 31 is located at the first end of slider 33, and guide post 34 is provided on the second end sidewall of slider 33. Movable shearing member 42 is connected to guide post 34, and guide post 34 is adapted to drive movable shearing member 42 to reciprocate. Specifically, the first end of movable shearing member 42 is adapted to shear with fixed shearing member 41, and the second end of movable shearing member 42 is connected to guide post 34, and guide post 34 is adapted to drive movable shearing member 42 to reciprocate.

[0030] In this embodiment, as Figures 3-4As shown, the fixed shearing component 41 is fixedly connected to the fixed component 1, and the movable shearing component 42 is rotatably connected to the fixed shearing component 41 via rivets 44. The first end of the movable shearing component 42 is provided with a shearing part suitable for shearing engagement with the fixed shearing component 41. The movable shearing component 42 has a strip-shaped limiting groove 43, and a guide post 34 is disposed in the strip-shaped limiting groove 43 and is suitable for driving the movable shearing component 42 to reciprocate. With this configuration, the movement path of the movable shearing component 42 is limited by the cooperation of the strip-shaped limiting groove 43 and the guide post 34, so that the movable shearing component 42 reciprocates stably, realizing the stable opening and closing shearing of the shearing assembly 4.

[0031] In this embodiment, as Figures 3-4 As shown, the elastic element 2 is a return spring. The first end of the return spring is connected to the fixed element 1, and the second end is connected to the sliding element 33. The movable component 3 is adapted to reciprocate along the extension and retraction direction of the return spring. Specifically, in the initial state, the first end of the sliding element 33 is close to the first end of the return spring; in the stretched state, the first end of the sliding element 33 moves toward the second end of the return spring. With this configuration, when the button 31 is pressed, pushing the sliding element 33 to move away from the button 31, the second end of the return spring moves away from the first end of the return spring to stretch; when the pushing force on the sliding element 33 is released, under its own stress, the second end of the return spring moves quickly toward the first end of the return spring to return to the initial state, while simultaneously driving the sliding element 33 to quickly move toward the button 31 to reset. The movement response is fast and smooth, and there is no jamming during the translation process, which can effectively ensure the normal operation of the printer. Specifically, hooks 21 are provided at both ends of the return spring, and the two ends of the return spring are connected to the fixed element 1 and the sliding element 33 respectively through the hooks 21.

[0032] In this embodiment, as Figures 5-7 As shown, a limiting baffle 5 is provided on one side of the fixed component 1, the fixed shearing component 41 is integrally formed on the limiting baffle 5, the movable component 3 is movably disposed between the fixed component 1 and the limiting baffle 5, and the movable shearing component 42 is disposed on the side of the limiting baffle 5 away from the fixed component 1. This arrangement allows the limiting baffle 5 to limit the movement of the movable component 3, ensuring the stability of its movement and thus maintaining the stability of the movable shearing component 42 during its shearing motion. Simultaneously, the limiting baffle 5 separates the movable component 3 and the movable shearing component 42, preventing mutual interference when they move simultaneously.

[0033] Specifically, the first and second ends of the movable shearing member 42 are bent, and there is a 90° angle between the first and second ends of the movable shearing member 42. The middle part of the movable shearing member 42 is rotatably connected to the limiting baffle 5 by a rivet 44. With this configuration, the bent movable shearing member 42 can further reduce the space required for movement compared to the vertically arranged shearing member, which can effectively ensure that the shearing assembly 4 can perform the shearing action completely and smoothly within the limited space of the printer.

[0034] A printer includes a linkage shearing structure as described above, wherein the fixing member 1 included in the linkage shearing structure is a fixing plate connected to the printer mechanism.

[0035] In summary, this linkage shearing structure, by pushing the movable component 3 to move along the first direction (X), causes the elastic element 2 to stretch and store energy. At this time, the movable shearing element 42 and the fixed shearing element 41 turn to a closed state. When the movable component 3 is released, the elastic element 2 releases energy and retracts to its initial position under its own stress, simultaneously driving the movable component 3 to move to its initial position. At this time, the movable shearing element 42 and the fixed shearing element 41 turn to an open state. This method of stretching and storing energy through the elastic element 2 and releasing and retracting to reset drives the movable component 3 to reciprocate translation, thereby driving the movable shearing element 42 to reciprocate to achieve... The shearing assembly 4 opens and closes for shearing. This linkage drive structure achieves stable shearing of consumables by the shearing assembly 4 through horizontal movement, and quick and accurate reset through the retraction of the elastic element 2. This achieves efficient shearing and reset within the limited space of the printer. At the same time, the translational movable component 3 serves as the drive structure, which greatly reduces the required space compared to the rotating linkage mechanism in the prior art. Moreover, the elastic element 2 only needs to extend and retract, and there will be no jamming during reset, which can ensure the stable translation of the movable component 3, thereby maintaining the shearing stability of the shearing assembly 4.

[0036] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
