Description

Technical Field

[0001] This invention relates to the field of printing equipment technology, and more particularly to a printer and a method for installing a cutter. Background Technology

[0002] Printers provided by related technologies typically include a frame, a printing assembly disposed on the frame, and a cutter disposed on the frame. The printing assembly is used to perform printing operations on printing media. Along the direction of movement of the printing media, the cutter is located downstream of the printing assembly. The cutter includes a stationary blade assembly and a moving blade assembly. The moving blade assembly is used to cooperate with the stationary blade assembly to cut the printing media.

[0003] However, due to processing and installation errors, the relative positions of the moving blade assembly and the stationary blade assembly after installation on the frame may not meet the design requirements, thus affecting the paper cutting effect of the cutter. Summary of the Invention

[0004] The purpose of this invention is to provide a printer and a cutter installation method to improve the paper cutting effect of the cutter.

[0005] On one hand, the present invention provides a printer comprising:

[0006] The frame includes a fixed frame, a first mounting frame and a second mounting frame, wherein the first mounting frame is connected to the fixed frame and the second mounting frame is arbitrarily connected to the fixed frame;

[0007] A cutter for cutting printing media, the cutter comprising a stationary blade assembly and a moving blade assembly, the stationary blade assembly being mounted on a first mounting bracket and the moving blade assembly being mounted on a second mounting bracket;

[0008] An adjusting member is movably connected to the fixed frame, and when the adjusting member moves relative to the fixed frame, it can drive the second mounting frame to move relative to the fixed frame in a first direction to adjust the relative position of the moving blade assembly and the stationary blade assembly.

[0009] Fasteners are used to lock the position of the second mounting bracket relative to the fixed bracket.

[0010] As a preferred technical solution for the printer, the second mounting bracket includes two abutting walls that are opposite to each other and spaced apart along the first direction, and the adjusting member includes a drive wheel that can rotate relative to the fixed frame, the drive wheel being inserted between the two abutting walls;

[0011] When the drive wheel rotates relative to the fixed frame, the drive wheel can abut against one of the two abutment walls to drive the second mounting frame to translate along the first direction.

[0012] As a preferred technical solution for the printer, the drive wheel is an eccentric wheel or a cam, and when the drive wheel is an eccentric wheel, the outer diameter of the eccentric wheel is equal to the distance between the two abutting walls.

[0013] As a preferred technical solution for the printer, the mounting bracket includes a support plate, the support plate having a first side and a second side disposed opposite to each other, the second mounting bracket being located on the first side of the support plate, and the second mounting bracket being supported by the support plate;

[0014] The adjusting component further includes a connecting shaft and an operating part. The connecting shaft is rotatably inserted into the support plate. The drive wheel is located on the first side of the support plate and is fixedly connected to the first end of the connecting shaft. The operating part is disposed at the second end of the connecting shaft and protrudes from the second side of the support plate. The operating part is used to drive the drive wheel to rotate relative to the fixed frame through the connecting shaft.

[0015] As a preferred technical solution for the printer, the mounting bracket further includes a middle shell and a bottom shell. The middle shell has a receiving cavity, a first opening, and a second opening. The support plate is disposed in the receiving cavity and divides the receiving cavity into a first mounting cavity located on a first side of the support plate and a second mounting cavity located on a second side of the support plate. The first opening communicates with the first mounting cavity. The moving blade assembly and the second mounting bracket can both be installed in the first mounting cavity through the first opening. The second opening communicates with the second mounting cavity. The operating part is opposite to the second opening. The bottom shell is detachably connected to the middle shell and is used to close the second opening.

[0016] The first mounting bracket includes a top cover, which is pivotally connected to the middle shell. The top cover is rotatable relative to the middle shell and has an open position and a closed position. The stationary blade assembly is fixedly connected to the top cover.

[0017] The frame also includes a cutter cover, which is detachably connected to the middle shell. The cutter cover is used to cover the moving blade assembly. When the cutter cover is installed on the middle shell and the upper cover is in the closed position, the upper cover and the cutter cover together close the first opening, and an outlet for outputting printing media is formed between the upper cover and the cutter cover.

[0018] As a preferred technical solution for the printer, the adjusting component includes a lead screw and a nut. The lead screw is disposed on the fixed frame and extends along the first direction. The lead screw can rotate relative to the fixed frame about its own axis. The nut is disposed on the second mounting frame, and the lead screw is threadedly connected to the nut. When the lead screw rotates, it can drive the second mounting frame and the moving blade assembly to translate together relative to the fixed frame along the first direction through the nut. Alternatively, the adjusting component includes a gear and a rack. The gear is disposed on the fixed frame and can rotate relative to the fixed frame about its own axis. The rack is disposed on the second mounting frame and extends along the first direction. Extending in the first direction, the gear meshes with the rack. When the gear rotates, it can drive the second mounting bracket and the moving blade assembly to translate relative to the fixed bracket along the first direction via the rack. Alternatively, the adjusting member includes a worm wheel and a worm. The worm wheel is disposed on the second mounting bracket and can rotate relative to the second mounting bracket about its own axis. The worm extends along the first direction, and the worm wheel is rotatably disposed on the second mounting bracket. The worm wheel meshes with the worm. When the worm rotates, it can drive the second mounting bracket and the moving blade assembly to translate relative to the fixed bracket along the first direction via the worm wheel.

[0019] As a preferred technical solution for the printer, the first of the fixed frame and the second mounting frame is provided with a guide groove extending along the first direction, and the printer further includes a snap-fit ​​part, which includes a guide plate and a buckle;

[0020] The first end of the guide plate is connected to the second of the fixed frame and the second mounting frame, the second end of the guide plate is suspended, the guide plate is inserted into the guide groove to limit the position of the second mounting frame relative to the fixed frame in the second direction, and the guide plate can slide relative to the guide groove in the first direction;

[0021] The buckle is fixedly connected to the second end of the guide plate. The buckle passes through the guide groove and engages with the first of the fixed frame and the second mounting frame to limit the position of the second mounting frame relative to the fixed frame in a third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0022] As a preferred technical solution for the printer, the moving blade assembly includes a moving blade bracket and a moving blade. The moving blade bracket is fixedly connected to the second mounting bracket, and the moving blade is movably connected to the moving blade bracket. The moving blade can move relative to the moving blade bracket and has an extended position and a retracted position.

[0023] The stationary blade assembly includes a stationary blade bracket, a stationary blade, and an elastic element. The stationary blade bracket is fixedly connected to the first mounting bracket. The stationary blade is mounted on the stationary blade bracket and can move relative to the stationary blade bracket along the direction of printing media movement. One end of the elastic element is connected to the stationary blade bracket, and the other end of the elastic element is connected to the stationary blade.

[0024] When the moving blade is in the extended position, the moving blade cooperates with the stationary blade to cut the printing medium. When the moving blade is in the retracted position, the moving blade and the stationary blade separate, and a channel for the printing medium to pass through is formed between the moving blade and the stationary blade.

[0025] The second mounting bracket is provided with a limiting part. The elastic member is used to ensure that the stationary blade always has a tendency to move along the printing medium movement direction and abut against the limiting part. The limiting part is used to support the stationary blade to position the engagement position of the stationary blade and the moving blade along the printing medium movement direction.

[0026] As a preferred technical solution for the printer, the first mounting bracket is pivotally connected to the fixed bracket, and the first mounting bracket is rotatable relative to the fixed bracket to have a first position and a second position. When the first mounting bracket is in the first position, the stationary blade assembly and the moving blade assembly cooperate to cut the printing medium. When the first mounting bracket is in the second position, the stationary blade assembly and the moving blade assembly separate. The printer further includes a locking member for locking the first mounting bracket in the first position; or...

[0027] The first mounting bracket is fixedly connected to the fixed bracket.

[0028] The printer provided by this invention has at least the following beneficial effects:

[0029] The printer includes a frame, a cutter, an adjusting component, and fasteners. The frame includes a fixed frame, a first mounting frame, and a second mounting frame. The first mounting frame is connected to the fixed frame, and the second mounting frame is adjustablely connected to the fixed frame. The cutter is used to cut the printing media and includes a stationary blade assembly and a moving blade assembly. The stationary blade assembly is mounted on the first mounting frame, and the moving blade assembly is mounted on the second mounting frame. The adjusting component is movably connected to the fixed frame, and when the adjusting component moves relative to the fixed frame, it can drive the second mounting frame to move relative to the fixed frame along a first direction to adjust the relative position of the moving blade assembly and the stationary blade assembly. The fasteners are used to lock the position of the second mounting frame relative to the fixed frame. By adjusting the position of the second mounting frame relative to the fixed frame along the first direction through the adjusting component, the relative position of the moving blade assembly and the stationary blade assembly is adjusted, so that the relative positional relationship between the moving blade assembly and the stationary blade assembly meets the design requirements. This compensates for the influence of processing and installation errors on the relative positional relationship between the moving blade assembly and the stationary blade assembly, and improves the paper cutting effect of the cutter.

[0030] On the other hand, the present invention provides a cutter mounting method, including a printer implementation of any of the above-described solutions, wherein the printer further includes a first reference surface and a second reference surface, the first reference surface being disposed on the stationary blade assembly or the first mounting bracket, and the second reference surface being disposed on the moving blade assembly or the second mounting bracket, the cutter mounting method comprising:

[0031] S100: Install the static blade assembly onto the first mounting bracket;

[0032] S200: Place the moving blade assembly in the second mounting bracket;

[0033] S300: Place the gauge block between the first reference plane and the second reference plane, such that the first side of the gauge block is opposite to the first reference plane and the second side of the gauge block is opposite to the second reference plane;

[0034] S400: Drive the adjusting member to move relative to the fixed frame, so that the second mounting bracket moves relative to the fixed frame in the first direction. When the first side of the gauge block abuts against the first reference surface and the second side of the gauge block abuts against the second reference surface, use the fastener to fix the position of the second mounting bracket relative to the fixed frame.

[0035] S500: Remove the gauge block from between the first reference plane and the second reference plane.

[0036] The cutting blade installation method provided by this invention has at least the following beneficial effects:

[0037] The cutter installation method is implemented using the aforementioned printer, which also includes a first reference surface and a second reference surface. The first reference surface is disposed on the stationary blade assembly or the first mounting bracket, and the second reference surface is disposed on the moving blade assembly or the second mounting bracket. The cutter installation method includes: installing the stationary blade assembly on the first mounting bracket, placing the moving blade assembly on the second mounting bracket, placing a gauge block between the first and second reference surfaces, with the first side of the gauge block facing the first reference surface and the second side of the gauge block facing the second reference surface, driving an adjusting member to move relative to a fixed bracket, so that the second mounting bracket moves relative to the fixed bracket in a first direction. When the first side of the gauge block abuts against the first reference surface and the second side of the gauge block abuts against the second reference surface, fasteners are used to fix the position of the second mounting bracket relative to the fixed bracket, and the gauge block is removed from between the first and second reference surfaces. This configuration allows the second mounting bracket to be accurately positioned relative to the fixed bracket by means of the first side of the gauge block abutting against the first reference surface and the second side of the gauge block abutting against the second reference surface during the movement of the second mounting bracket by the adjusting member driving the second mounting bracket in the first direction, thereby improving the adjustment efficiency and accuracy of the relative installation position between the moving blade assembly and the stationary blade assembly.

[0060] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0061] Please refer to Figures 1 to 4 This embodiment provides a printer, which includes a frame 1, a cutter, an adjusting member 3, and fasteners 4. The frame 1 includes a fixed frame 11, a first mounting frame 12, and a second mounting frame 13. The first mounting frame 12 is connected to the fixed frame 11, and the second mounting frame 13 is tunably connected to the fixed frame 11. The cutter is used to cut the printing medium and includes a stationary blade assembly 21 and a moving blade assembly 22. The stationary blade assembly 21 is mounted on the first mounting frame 12, and the moving blade assembly 22 is mounted on the second mounting frame 13. The adjusting member 3 is movably connected to the fixed frame 11, and when the adjusting member 3 moves relative to the fixed frame 11, it can drive the second mounting frame 13 relative to the fixed frame 11 along a first direction (e.g., ...). Figure 3The movement (in the direction indicated by the arrow ab) adjusts the relative position of the moving blade assembly 22 and the stationary blade assembly 21; the fastener 4 is used to lock the position of the second mounting bracket 13 relative to the fixed bracket 11. The printer provided in this embodiment adjusts the position of the second mounting bracket 13 relative to the fixed bracket 11 along the first direction using the adjusting member 3, thereby adjusting the relative position of the moving blade assembly 22 and the stationary blade assembly 21. This ensures that the relative positional relationship between the moving blade assembly 22 and the stationary blade assembly 21 meets the design requirements, compensating for the impact of processing and installation errors on the relative positional relationship between the moving blade assembly 22 and the stationary blade assembly 21, and improving the paper cutting effect of the cutter.

[0062] Alternatively, please refer to Figure 3 In this embodiment, the second mounting bracket 13 includes two abutment walls 131 that are opposite to and spaced apart along a first direction. The adjusting member 3 includes a drive wheel 31 that can rotate relative to the fixed bracket 11. The drive wheel 31 is inserted between the two abutment walls 131. When the drive wheel 31 rotates relative to the fixed bracket 11, the drive wheel 31 can abut against one of the two abutment walls 131 to drive the second mounting bracket 13 to translate along the first direction. This arrangement allows the position of the second mounting bracket 13 relative to the fixed bracket 11 along the first direction to be adjusted by rotating the drive wheel 31, thereby adjusting the relative position of the moving blade assembly 22 and the stationary blade assembly 21, which is easy to operate.

[0063] As an alternative, the adjusting component 3 includes a lead screw and a nut. The lead screw is mounted on the fixed frame 11 and extends along a first direction, allowing it to rotate relative to the fixed frame 11 around its own axis. The nut is mounted on the second mounting frame 13, and the lead screw and nut are threadedly connected. When the lead screw rotates, it drives the second mounting frame 13 and the moving blade assembly 22 to translate together relative to the fixed frame 11 along the first direction via the nut. With this configuration, by rotating the lead screw to cause the nut to drive the second mounting frame 13 to translate relative to the fixed frame 11 along the first direction, the relative position of the moving blade assembly 22 and the stationary blade assembly 21 can also be adjusted.

[0064] As an alternative, the adjusting component 3 includes a gear and a rack. The gear is mounted on the fixed frame 11 and can rotate relative to the fixed frame 11 around its own axis. The rack is mounted on the second mounting frame 13 and extends along a first direction. The gear meshes with the rack. When the gear rotates, it can drive the second mounting frame 13 and the moving blade assembly 22 to translate together relative to the fixed frame 11 along the first direction via the rack. With this configuration, by rotating the gear to drive the rack to translate the second mounting frame 13 relative to the fixed frame 11 along the first direction, the relative position of the moving blade assembly 22 and the stationary blade assembly 21 can also be adjusted.

[0065] As an alternative, the adjusting component 3 includes a worm gear and a worm. The worm is mounted on the fixed frame 11 and can rotate relative to the fixed frame 11 around its own axis. The worm extends along a first direction. The worm gear is mounted on the second mounting frame 13 and can rotate relative to the second mounting frame 13 around its own axis. The worm gear meshes with the worm. When the worm rotates, it can drive the second mounting frame 13 and the moving blade assembly 22 to translate together relative to the fixed frame 11 along the first direction via the worm gear. With this configuration, by rotating the worm and causing the worm gear to drive the second mounting frame 13 to translate relative to the fixed frame 11 along the first direction, the relative position of the moving blade assembly 22 and the stationary blade assembly 21 can also be adjusted.

[0066] Alternatively, please refer to Figure 3 In this embodiment, the drive wheel 31 is an eccentric wheel. The outer diameter of the eccentric wheel is equal to the distance between the two abutment walls 131. With this configuration, the outer circumferential surface of the eccentric wheel and the two abutment walls 131 can always remain in contact along the first direction, so that the relative position of the eccentric wheel and the second mounting bracket 13 along the first direction can remain stable. When the second mounting bracket 13 moves to a suitable position along the first direction under the drive of the eccentric wheel, the eccentric wheel can reliably maintain the second mounting bracket 13 in that position without any external force acting on it. This makes it easy to lock the position of the second mounting bracket 13 relative to the fixed bracket 11 using the fastener 4, which is convenient to operate and provides high precision in adjusting the relative position of the moving blade assembly 22 and the stationary blade assembly 21.

[0067] As an alternative, the drive wheel 31 can also be a cam, or the drive wheel 31 can be a roller that can roll in the first direction.

[0068] Alternatively, please refer to Figure 3 and Figure 4In this embodiment, the fixing frame 11 includes a support plate 111, which has a first side and a second side disposed opposite to each other. The second mounting frame 13 is located on the first side of the support plate 111 and is supported by the support plate 111. The adjusting member 3 also includes a connecting shaft 32 and an operating part 33. The connecting shaft 32 is rotatably inserted into the support plate 111. The drive wheel 31 is located on the first side of the support plate 111 and is fixedly connected to the first end of the connecting shaft 32. The operating part 33 is disposed on the second end of the connecting shaft 32 and protrudes from the second side of the support plate 111. The operating part 33 is used to drive the drive wheel 31 to rotate relative to the fixing frame 11 through the connecting shaft 32. This configuration allows the operator to drive the connecting shaft 32 to rotate via the operating unit 33 on the second side of the support plate 111. The connecting shaft 32 drives the drive wheel 31 to rotate relative to the fixed frame 11, thereby driving the second mounting frame 13 located on the first side of the support plate 111 to move along the first direction. This enables adjustment of the relative positions of the moving blade assembly 22 and the stationary blade assembly 21 along the first direction. The operating unit 33 has a large operating space and is flexible in operation. Furthermore, the efficient use of space on both sides of the support plate 111 contributes to the printer's structural compactness. Specifically, the support plate 111 has mounting holes 120, and the connecting shaft 32 is inserted into these holes. The shaft diameter of the connecting shaft 32 matches the diameter of the mounting hole 120. The operating unit 33 drives the connecting shaft 32 and the drive wheel 31 to rotate together around the axis of the connecting shaft 32. This configuration improves the positional stability of the adjusting member 3 relative to the support plate 111, thereby improving the stability of the adjusting member 3 driving the second mounting frame 13 to move along the first direction.

[0069] Optionally, the operating part 33 includes a first mating part 331 disposed at the second end of the connecting shaft 32. The first mating part 331 is configured to engage with and rotate with a second mating part of a compatible tool (e.g., a wrench). One of the first mating part 331 and the second mating part is a groove, and the other is a protrusion. With this configuration, the operating part 33 is driven to rotate by the tool, and then the operating part 33 drives the drive wheel 31 to rotate relative to the fixed frame 11 about the axis of the connecting shaft 32 via the connecting shaft 32. In this embodiment, an exemplary scheme is provided in which the first mating part 331 is a groove and the second mating part is a protrusion. Both the protrusion and the groove can be configured as a straight line, a cross shape, a star shape, or a regular polygon, etc.

[0070] As an alternative, the operating unit 33 includes a knob located on the second side of the support plate 111. By rotating the knob, the knob drives the operating unit 33 to rotate, which in turn enables the operating unit 33 to drive the connecting shaft 32 to drive the drive wheel 31 to rotate around the axis of the connecting shaft 32 relative to the fixed frame 11.

[0071] As an alternative, the printer also includes a motor, which is connected to the drive wheel 31 and drives the drive wheel 31 to rotate.

[0072] Alternatively, please refer to Figures 1 to 4 The mounting bracket 11 also includes a middle shell 112 and a bottom shell 113. The middle shell 112 has a receiving cavity, a first opening 119, and a second opening. A support plate 111 is disposed in the receiving cavity and divides the receiving cavity into a first mounting cavity 114 located on the first side of the support plate 111 and a second mounting cavity 117 located on the second side of the support plate 111. The first opening 119 communicates with the first mounting cavity 114. The moving blade assembly 22 and the second mounting bracket 13 can both be installed in the first mounting cavity 114 through the first opening 119. The second opening communicates with the second mounting cavity 117. The operating part 33 is opposite to the second opening. The bottom shell 113 is detachably connected to the middle shell 112. 13 is used to close the second opening; the first mounting bracket 12 includes an upper cover 121, which is pivotally connected to the middle shell 112. The upper cover 121 can rotate relative to the middle shell 112 to have an open position and a closed position. The stationary blade assembly 21 is fixedly connected to the upper cover 121; the frame 1 also includes a cutter cover 14, which is detachably connected to the middle shell 112. The cutter cover 14 is used to cover the moving blade assembly 22. When the cutter cover 14 is installed on the middle shell 112 and the upper cover 121 is in the closed position, the upper cover 121 and the cutter cover 14 together close the first opening 119, and an outlet 6 for outputting printing media is formed between the upper cover 121 and the cutter cover 14. This arrangement ensures that when the printer is working normally, the upper cover 121 and the cutter cover 14 together close the first opening 119, making it difficult for the user to access the adjusting member 3, the moving blade assembly 22, and the fastener 4, thereby maintaining a stable relative position between the second mounting bracket 13 and the moving blade assembly 22. Preferably, please refer to Figure 3 The first mounting cavity 114 includes a first cavity 115 and a second cavity 116 that are connected. The moving blade assembly 22 and the second mounting bracket 13 are both mounted in the first cavity 115 through the first opening 119. The second cavity 116 is used to hold the paper roll for drawing out the printing medium.

[0073] Alternatively, please refer to Figure 4One of the cutter cover 14 and the middle shell 112 is provided with a snap-fit ​​hole 141, and the other is provided with a snap-fit ​​protrusion 150. When the cutter cover 14 is installed on the middle shell 112, the snap-fit ​​protrusion 150 engages with the snap-fit ​​hole 141. This configuration ensures the stability of the relative position of the cutter cover 14 and the middle shell 112 during normal printer operation through the snap-fit ​​engagement of the snap-fit ​​protrusion 150 and the snap-fit ​​hole 141. In this embodiment, an exemplary configuration is provided where the middle shell 112 is provided with a snap-fit ​​protrusion 150 and the cutter cover 14 is provided with a snap-fit ​​hole 141. In other embodiments, the middle shell 112 may also have a snap-fit ​​hole 141, and the cutter cover 14 may have a snap-fit ​​protrusion 150.

[0074] Alternatively, please refer to Figure 3 and Figure 4 In this embodiment, the fastener 4 passes through the second mounting bracket 13 via the first mounting cavity 114 and is threadedly connected to the support plate 111. When the cutter cover 14 is installed on the middle shell 112, the cutter cover 14 covers the fastener 4 to prevent the user from contacting the fastener 4, ensuring the relative position stability of the second mounting bracket 13 and the support plate 111, thereby ensuring the stability of the relative positional relationship between the moving blade assembly 22 and the stationary blade assembly 21. In other embodiments, the fastener 4 can also pass through the support plate 111 via the second mounting cavity 117 and be threadedly connected to the second mounting bracket 13.

[0075] Alternatively, please refer to Figures 4 to 7 The printer further includes a first of the two mounting brackets 11 and 13, which has a guide groove 118 extending in a first direction. The printer also includes a snap-fit ​​part 5, which includes a guide plate 51 and a latch 52. The first end of the guide plate 51 is connected to the second of the two mounting brackets 11 and 13, and the second end of the guide plate 51 is suspended. The guide plate 51 is inserted into the guide groove 118 to restrict the second mounting bracket 13 relative to the mounting bracket 11 in a second direction (e.g., ...). Figure 7 The guide plate 51 is positioned in the direction indicated by the middle arrow cd, and the guide plate 51 can slide relative to the guide groove 118 in the first direction; the buckle 52 is fixedly connected to the second end of the guide plate 51, and the buckle 52 passes through the guide groove 118 and engages with the first of the two, the fixing frame 11 and the second mounting frame 13, to limit the second mounting frame 13 relative to the fixing frame 11 in a third direction (such as...). Figure 7The first, second, and third directions are perpendicular to each other, as indicated by the arrow ef. This arrangement restricts the position of the second mounting bracket 13 relative to the fixed bracket 11 along the second direction through the cooperation of the guide plate 51 and the guide groove 118. The first mounting bracket 12 is restricted from the fixed bracket 11 along the third direction by the snap fastener 52 engaging with the fixed bracket 11. This ensures that the adjusting member 3 can only drive the second mounting bracket 13 to move relative to the fixed bracket 11 along the first direction, meaning the adjusting member 3 can only adjust the position of the moving blade assembly 22 relative to the stationary blade assembly 21 along the first direction, thus improving the stability of the adjustment. In this embodiment, the guide groove 118 is provided on the fixed bracket 11, and the snap fastener 5 is provided on the second mounting bracket 13. In other embodiments, the guide groove 118 can also be provided on the second mounting bracket 13, and the snap fastener 5 on the fixed bracket 11.

[0076] Alternatively, please continue to refer to Figures 4 to 7 The second mounting bracket 13 has a snap-fit ​​portion 5 at both ends along the second direction, and the fixing bracket 11 has a guide groove 118 at both ends along the second direction. The guide grooves 118 at both ends of the fixing bracket 11 correspond one-to-one with the snap-fit ​​portions 5 at both ends of the second mounting bracket 13. This arrangement further improves the stability of the second mounting bracket 13 moving relative to the fixing bracket 11 along the first direction. Preferably, along the second direction, the guide groove 118 has a first groove wall 130 and a second groove wall 140 that are opposite to each other and spaced apart. Along the second direction, the two first groove walls 130 of the two guide grooves 118 located at both ends of the fixing frame 11 are situated between the two second groove walls 140. The thickness of the guide plate 51 is less than the width of the guide groove 118. The second end of the guide plate 51 can elastically deform relative to the first end of the guide plate 51, allowing the buckle 52 to pass through the guide groove 118. After the buckle 52 passes through the guide groove 118, the guide plate 51, under the action of its elastic restoring force, abuts against the first groove wall 130 or the second groove wall 140 of the guide groove 118, causing the buckle 52 to engage with the fixing frame 11. This arrangement improves the reliability of the buckle 52 engaging with the fixing frame 11 and the reliability of the guide plate 51 in defining the position of the second mounting frame 13 relative to the fixing frame 11 along the second direction. More preferably, both ends of the fixing frame 11 along the second direction are provided with at least two guide grooves 118 spaced apart along the first direction. More preferably, the guide plate 51 and the buckle 52 of the snap-fit ​​part 5 are integrally formed, and the second mounting bracket 13 and each snap-fit ​​part 5 are integrally formed. Specifically, the guide groove 118 is provided on the support plate 111, and the buckle 52 passes through the guide groove 118 and snaps into the support plate 111.

[0077] Alternatively, please continue to refer to Figure 3 , Figure 4 and Figure 6The moving blade assembly 22 includes a moving blade support 221 and a moving blade 222. The moving blade support 221 is fixedly connected to the second mounting bracket 13, and the moving blade 222 is movably connected to the moving blade support 221. The moving blade 222 can move relative to the moving blade support 221 and has an extended position and a retracted position. The stationary blade assembly 21 includes a stationary blade support 212, a stationary blade 211, and an elastic member 213. The stationary blade support 212 is fixedly connected to the first mounting bracket 12. The stationary blade 211 is mounted on the stationary blade support 212 and can move relative to the stationary blade support 212 along the direction of printing media movement. One end of the elastic member 213 is connected to the stationary blade support 212. The other end is connected to the stationary blade 211; when the moving blade 222 is in the extended position, the moving blade 222 cooperates with the stationary blade 211 to cut the printing medium; when the moving blade 222 is in the retracted position, the moving blade 222 and the stationary blade 211 separate, and a channel for the printing medium to pass through is formed between the moving blade 222 and the stationary blade 211; the second mounting bracket 13 is provided with a limiting part 132, and the elastic member 213 is used to make the stationary blade 211 always have a tendency to move along the printing medium movement direction and abut against the limiting part 132. The limiting part 132 is used to support the stationary blade 211 to position the cooperation position of the stationary blade 211 and the moving blade 222 along the printing medium movement direction. This configuration improves the flexibility of the movement direction of the second mounting bracket 13 relative to the fixed bracket 11, helps to make reasonable use of the installation space of the frame 1, improves the structural compactness of the printer, and when the second mounting bracket 13 drives the moving blade 222 to the set position along the first direction, the stationary blade 211 can automatically abut against the second mounting bracket 13 along the printing media movement direction under the action of the elastic element 213, ensuring the relative position of the moving blade 222 and the stationary blade 211 along the printing media movement direction. Preferably, in this embodiment, the elastic element 213 is a metal spring, one end of which is connected to the stationary blade support 212, and the other end abuts against the stationary blade 211. In other embodiments, the elastic element 213 can also be a compression spring or a tension spring.

[0078] Alternatively, please refer to Figure 6 The stationary blade support 212 is provided with a guide post 215, the axial direction of which extends along the direction of movement of the printing medium. The stationary blade 211 is provided with a guide hole 214 that matches the guide post 215. The guide hole 214 is sleeved with the guide post 215, allowing the stationary blade 211 to move relative to the stationary blade support 212 along the axial direction of the guide post 215. This configuration improves the stability of the stationary blade 211 moving along the direction of movement of the printing medium under the drive of the elastic element 213.

[0079] Alternatively, please refer to Figure 5In this embodiment, the first mounting bracket 12 is pivotally connected to the fixed bracket 11. The first mounting bracket 12 can rotate relative to the fixed bracket 11 and has a first position and a second position. When the first mounting bracket 12 is in the first position, the stationary blade assembly 21 and the moving blade assembly 22 cooperate to cut the printing medium. When the first mounting bracket 12 is in the second position, the stationary blade assembly 21 and the moving blade assembly 22 are separated. The printer also includes a locking member (not shown in the figure), which is used to lock the first mounting bracket 12 in the first position. This arrangement ensures the stability of the cooperation between the stationary blade assembly 21 and the moving blade assembly 22 when the printer is working.

[0080] Alternatively, please refer to Figure 4 and Figure 8 The printer also includes a printing assembly 7, located upstream of the cutter along the direction of movement of the printing medium. The printing assembly 7 includes a print head 71 and a printing roller 72. The printing roller 72 is mounted on a first mounting bracket 12, and the print head 71 is mounted on a second mounting bracket 13. A locking element includes a limiting protrusion on the printing roller 72 and a limiting groove on the second mounting bracket 13. When the first mounting bracket 12 is in a first position, the limiting protrusion engages with the limiting groove, fixing the relative positions of the first mounting bracket 12 and the second mounting bracket 13. The printing roller 72 and the print head 71 cooperate to print on the printing medium. In other embodiments, the locking element includes a locking hook on the first mounting bracket 12 and a locking shaft on the fixed bracket 11. The locking hook engages with the locking shaft to lock the first mounting bracket 12 in the first position.

[0081] As an alternative, the first mounting bracket 12 can also be fixedly connected to the fixing bracket 11.

[0082] This embodiment also provides a method for installing a cutter, which is implemented using the printer described above.

[0083] Please refer to Figure 8 The printer also includes a first reference surface 81 and a second reference surface 82. The first reference surface 81 is disposed on the stationary blade assembly 21 or the first mounting bracket 12, and the second reference surface 82 is disposed on the moving blade assembly 22 or the second mounting bracket 13. In this embodiment, the first reference surface 81 is disposed on the stationary blade 211 of the stationary blade assembly 21, and the second reference surface 82 is disposed on the moving blade support 221 of the moving blade assembly 22. In other embodiments, the first reference surface 81 may be disposed on the stationary blade support 212 or the first mounting bracket 12 of the stationary blade assembly 21, and the second reference surface 82 may be disposed on the moving blade 222 or the second mounting bracket 13 of the moving blade assembly 22.

[0084] Please refer to Figure 9 The method for installing the cutter includes the following steps:

[0085] S100: Install the stationary blade assembly 21 onto the first mounting bracket 12.

[0086] S200: Place the moving blade assembly 22 on the second mounting bracket 13.

[0087] S300: Place the gauge block 9 between the first reference surface 81 and the second reference surface 82, such that the first side of the gauge block 9 is opposite to the first reference surface 81 and the second side of the gauge block 9 is opposite to the second reference surface 82.

[0088] S400: Drive the adjustment member 3 to move relative to the fixed frame 11 so that the second mounting bracket 13 moves relative to the fixed frame 11 in the first direction. When the first side of the gauge block 9 abuts against the first reference surface 81 and the second side of the gauge block 9 abuts against the second reference surface 82, use the fastener 4 to fix the position of the second mounting bracket 13 relative to the fixed frame 11.

[0089] S500: Remove gauge block 9 from between the first reference plane 81 and the second reference plane 82.

[0090] The cutting tool installation method provided in this embodiment can accurately position the second mounting bracket 13 relative to the fixed bracket 11 by means of the first side of the gauge block 9 abutting against the first reference surface 81 and the second side abutting against the second reference surface 82 during the process of the adjusting member 3 driving the second mounting bracket 13 to move along the first direction. This improves the adjustment efficiency and accuracy of the installation position of the moving blade 222 relative to the stationary blade 211 along the first direction (the movement direction of the moving blade 222).

[0091] It should be noted that when the upper cover 121 is in the closed position, the first reference surface 81 and the second reference surface 82 are opposite to each other and spaced apart along the movement direction of the moving blade 222. Step S300 is executed after the upper cover 121 is rotated to the closed position.

[0092] Optionally, when the second reference surface 82 is set on the stationary blade 211, the stationary blade support 212 includes a support surface 216, and the stationary blade 211 is supported on the support surface 216. Along the movement direction of the moving blade 222, the distance between the support surface 216 and the first reference surface 81 is less than the distance between the second reference surface 82 and the first reference surface 81. In step S300, when the gauge block 9 is placed between the first reference surface 81 and the second reference surface 82, the lower surface of the gauge block 9 is supported on the support surface 216. This arrangement ensures that the gauge block 9 is supported by the support surface 216 after being placed between the first reference surface 81 and the second reference surface 82, so that the support member 216 can limit the placement position of the gauge block 9 in the printing media movement direction, eliminating the need to manually hold the gauge block 9, thus facilitating the adjustment operation of the adjustment member 3.
