Description

Technical Field

[0001] This application relates to the field of printing equipment technology, and more particularly to a consumable box and a printer. Background Technology

[0002] Currently, the consumable box contains a label roll. During the printing process, the label paper on the label roll extends out of the consumable box and is held by the printing roller and print head for printing, preventing the label paper from retracting into the consumable box.

[0003] However, after printing, the print roller moves away from the print head and releases the label paper. The label paper may then retract into the consumable cartridge, causing the label paper roll to unravel and making it impossible to feed the paper back during subsequent printing. Related technologies use an anti-retraction structure within the consumable cartridge to prevent this, but this anti-retraction structure can interfere with the label paper roll, preventing smooth paper feeding. Summary of the Invention

[0004] This application provides a consumable box and a printer that can solve the technical problem of interference between the label paper retraction structure and the label paper roll.

[0005] In a first aspect, embodiments of this application provide a consumable box, which includes: The box body has a first inner sidewall; A label roll includes label paper and a roll movably connected to the box body. The label paper includes a winding portion wound on the roll and a dispensing portion located outside the roll. The dispensing portion is used to feed the paper in the paper feeding direction. A pressing member is located on opposite sides of the dispensing portion, and the pressing member is movably connected to the box body so as to be able to switch between a pressing position and a releasing position.

[0009] In some embodiments, the driving member and the pressing member are arranged axially along the first rotating shaft, with the driving member located below the pressing member.

[0010] In some embodiments, the consumable box further includes a connecting plate, which is rotatably connected to the first rotating shaft, and is also connected to the pressing member and the driving member.

[0011] In some embodiments, the drive member includes an abutment surface disposed toward the first inner sidewall, the abutment surface being used to abut against the push rod extending into the housing to drive the drive member to rotate away from the first inner sidewall via the push rod; When the pressing member is located in the pressing position, the orthographic projection of the abutting surface onto the first plane is located within the orthographic projection of the insertion hole wall onto the first plane, and the first plane is perpendicular to the axial direction of the insertion hole.

[0012] In some embodiments, the orthographic projection of the insertion hole wall onto the first plane is a first projection, the position closest to the first inner wall on the first projection is a first position, and the orthographic projection of the abutment surface onto the first plane is a second projection. When the pressing member is located at the pressing position, the distance between the second projection and the first position along the axis perpendicular to the insertion hole is d, where d satisfies: 2mm≤d≤5mm.

[0013] In some embodiments, the drive member further includes a guide surface connected to the abutment surface, and the abutment surface, the guide surface, and the insertion hole are arranged sequentially along the axial direction of the insertion hole. The guide surface is used to contact the push rod after the push rod is inserted into the insertion hole to guide the push rod to abut against the abutment surface.

[0014] In some embodiments, the pressing member and the driving member are offset in a direction perpendicular to the axial direction of the first rotating shaft, and the pressing member is disposed closer to the first inner sidewall relative to the driving member.

[0015] In some embodiments, the consumable box further includes a guide plate connected to the box body and extending along the paper feeding direction to guide the dispensing portion to feed paper along the paper feeding direction; The guide plate has an opening groove facing the first inner sidewall. When the pressing member is switched to the pressing position, the pressing member extends out from the opening groove and presses the dispensing part against the first inner sidewall.

[0016] In some embodiments, when the pressing member is in the pressing position, the height by which the pressing member protrudes toward the first inner wall relative to the guide plate is a1, where a1 satisfies: 1mm≤a1≤3mm.

[0017] In some embodiments, when the pressing member is in the released position, the height by which the pressing member protrudes relative to the guide plate toward the first inner wall is a2, where a2 satisfies: 0mm≤a2≤1mm.

[0018] In some embodiments, the guide plate includes a first end and a second end, the first end and the second end being arranged along the paper feeding direction, and the opening groove being defined between the first end and the second end; When the pressing member is in the released position, a portion of the pressing member is located within the opening groove, and the distance between the pressing member and the first end along the paper feeding direction is b1, and the distance between the pressing member and the second end along the paper feeding direction is b2. b1 and b2 satisfy: 5mm≤b1≤9mm, 5mm≤b2≤9mm.

[0020] In some embodiments, the consumable box further includes: A partition is connected to the box body, and the winding portion and the pressing member are located on opposite sides of the partition.

[0021] In some embodiments, the consumable box further includes a pressure plate connected to the first inner sidewall, and the pressure plate protrudes toward the pressure member to form a convex arc surface; When the pressing member is in the pressing position, the pressing member presses the dispensing portion against the convex arc surface.

[0022] In some embodiments, the consumable cartridge includes a ribbon assembly movably connected to the cartridge body, the ribbon assembly being used to dispense ribbons; When the pressing member switches between the pressing position and the releasing position, the pressing member and the ribbon assembly are spaced apart.

[0023] Secondly, embodiments of this application provide a printer, which includes: The printer body has a receiving slot; A push rod is disposed within the receiving groove and connected to the bottom surface of the receiving groove; As described in any of the preceding claims, the consumable box is assembled within the receiving slot.

[0024] The consumable box and printer based on the embodiments of this application have at least the following beneficial effects: By movably positioning the roller within the consumable cartridge, the roller can dispense label paper. The portion wound around the roller is the label paper winding portion, while the portion outside the roller is the label paper dispensing portion. A pressing member is movably connected to the cartridge body, with the pressing member and the first inner wall of the cartridge body located on opposite sides of the dispensing portion. When the pressing member is in the pressing position, it presses the label paper dispensing portion against the first inner wall, preventing the label paper from retracting into the cartridge body. When the pressing member is in the releasing position, it disengages from the label paper dispensing portion, allowing the label paper dispensing portion to feed along the paper feed direction for printing. Furthermore, the pressing member maintains a distance from the label paper winding portion throughout the transition from the pressing to the releasing position, preventing interference and ensuring smooth paper feeding for improved print quality.

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] In related technologies, the consumable box is equipped with an anti-reverse structure, the main function of which is to prevent the dispensed label paper from returning to the consumable box. However, during the normal paper feeding process, the anti-reverse structure can interfere with the label paper roll, causing the label paper to not feed smoothly.

[0030] Specifically, when the anti-reverse structure is in an unlocked state (i.e., the anti-reverse structure does not apply pressure to the label paper), the label paper may accidentally cause the anti-reverse structure to rotate during the paper feeding process, causing the anti-reverse structure to change from an unlocked state to a locked state (i.e., the anti-reverse structure presses against the label paper), thereby hindering the smooth feeding of the label paper.

[0031] Firstly, please refer to Figures 1 to 3 To address the aforementioned technical problems, this application provides a consumable box 100. The consumable box 100 includes a box body 1, a label roll 2, and a pressing member 3. The box body 1 has a first inner sidewall 11 inside. The label roll 2 includes label paper 21 and a roll 22 movably connected to the box body 1. The label paper 21 includes a winding portion 211 wound on the roll 22 and a dispensing portion 212 located outside the roll 22. The dispensing portion 212 is used to feed paper along the paper feeding direction. The pressing member 3 and the first inner sidewall 11 are located on opposite sides of the dispensing portion 212. The pressing member 3 is movably connected to the box body 1 so as to be able to switch between a pressing position and a releasing position. When the pressing member 3 is in the pressing position, the pressing member 3 presses against the dispensing portion 212 against the first inner sidewall 11. When the pressing member 3 is in the releasing position, the pressing member 3 is disengaged from the dispensing portion 212, and the pressing member 3 is spaced apart from the winding portion 211 during the process of switching from the pressing position to the releasing position.

[0032] Optionally, the box body 1 is a structure that defines the outer contour shape of the consumable box 100. The box body 1 includes a peripheral side plate, a first side plate and a second side plate. The first side plate and the second side plate are arranged opposite to each other. The peripheral side plate is located between the first side plate and the second side plate, and the peripheral side plate is connected to both the first side plate and the second side plate, so that the peripheral side plate, the first side plate and the second side plate can surround and define the mounting cavity. The side of the peripheral side plate facing the mounting cavity includes a first inner sidewall 11.

[0033] The label roll 2 is disposed in the mounting cavity, and the roll 22 is rotatably connected to the first side plate or the second side plate, so that the roll 22 can rotate around the first axis. The label paper 21 includes a winding portion 211 wound on the roll 22 and a dispensing portion 212 located outside the roll 22. During printing, the winding portion 211 can be driven to detach from the roll 22 and become the dispensing portion 212 by rotating the roll 22. The dispensing portion 212 can then feed paper along the paper feeding direction to achieve printing.

[0034] Combination Figure 4 In this embodiment, the pressing member 3 is rotatably connected to the box body 1, allowing the pressing member 3 to rotate around a second axis, which can be parallel to the first axis. The pressing member 3 can rotate around the second axis toward the first inner wall 11 to a pressing position, and can also rotate around the second axis away from the first inner wall 11 to a releasing position. In other embodiments, the pressing member 3 can also be slidably connected to the box body 1, allowing the pressing member 3 to slide toward the first inner wall 11 to a pressing position, and can also slide away from the first inner wall 11 to a releasing position.

[0035] Combination Figure 5 and Figure 6 When the pressing member 3 is in the pressing position, it can press the dispensing portion 212 of the label 21 against the first inner sidewall 11, preventing the label 21 from retracting into the box body 1. Figure 7 and Figure 8 When the pressing member 3 is in the released position, the pressing member 3 can disengage from the dispensing part 212 of the label paper 21, so that the dispensing part 212 of the label paper 21 can feed paper in the paper feeding direction for printing. In addition, during the process of switching from the pressing position to the released position, the pressing member 3 is always kept at a distance from the winding part 211 of the label paper 21, which can avoid interference between the pressing member 3 and the winding part 211 of the label paper 21, so that the dispensing part 212 of the label paper 21 can feed paper smoothly and improve the printing quality.

[0036] Please see Figure 4 In some embodiments, the consumable box 100 further includes a reset member 4, one end of which is connected to the box body 1 and the other end of which is connected to the pressing member 3. The reset member 4 is used to drive the pressing member 3 to move toward the first inner sidewall 11 to the pressing position.

[0037] Optionally, when the pressing member 3 is rotatably connected to the box body 1 via a rotating shaft, the resetting member 4 can be a torsion spring. The torsion spring can be sleeved on the rotating shaft, with one end of the torsion spring abutting against the box body 1 and the other end abutting against the pressing member 3. This allows the resetting member 4 to drive the pressing member 3 to move towards the first inner wall 11 to the pressing position, thereby pressing the dispensing portion 212 of the label paper 21 against the first inner wall 11. When the consumable box 100 is not in use, this prevents the dispensing portion 212 of the label paper 21 from retracting onto the roll 22. When the pressing member 3 is slidably connected to the box body 1, the resetting member 4 can be a spring. One end of the spring is connected to the box body 1, and the other end of the spring is connected to the pressing member 3. The resetting member 4 can also drive the pressing member 3 to move towards the first inner wall 11 to the pressing position.

[0038] Please see Figure 1 , Figures 5 to 8 In some embodiments, the housing 1 has an insertion hole 12 facing the pressing member 3. The housing 1 is used to be assembled in the receiving groove 202 of the printer 200, and the insertion hole 12 is used to allow the push rod 203 on the printer 200 to extend into the housing 1 so as to drive the pressing member 3 to move away from the first inner sidewall 11 to the released position.

[0039] Optionally, the printer 200 includes a printer body 201, which has a receiving groove 202. The push rod 203 is a long straight rod connected to the bottom surface of the receiving groove 202 and extends along the depth direction of the receiving groove 202. The second side plate of the box body 1 is provided with an insertion hole 12, the diameter of which is larger than the diameter of the push rod 203.

[0040] More specifically, when the consumable box 100 is assembled in the receiving groove 202, the second side plate of the box body 1 is positioned opposite to the bottom surface of the receiving groove 202. The push rod 203 can pass through the insertion hole 12 and extend into the box body 1, so that the push rod 203 can contact the pressing member 3 and drive the pressing member 3 to move away from the first inner side wall 11, so that the pressing member 3 can move to the released position, and then the label paper 21 dispensing part 212 can feed paper normally along the paper feeding direction, so that the printer 200 can print the label paper 21.

[0041] When the consumable box 100 is removed from the receiving slot 202, the push rod 203 is pulled out from the insertion hole 12 and disengages from the pressing member 3. Driven by the reset member 4, the pressing member 3 can move to the pressing position, thereby pressing the dispensing portion 212 of the label 21 against the first inner sidewall 11, preventing the dispensing portion 212 of the label 21 from retracting onto the roll 22. Therefore, placing the consumable box 100 into the receiving slot 202 allows the pressing member 3 to move to the loosened position, and removing the consumable box 100 from the receiving slot 202 allows the pressing member 3 to move to the pressing position, making it convenient to use the consumable box 100.

[0042] Please see Figure 1 , Figures 5 to 8 In some embodiments, the consumable box 100 further includes a first rotating shaft 5 and a driving member 6. The first rotating shaft 5 is connected to the box body 1, the pressing member 3 is rotatably connected to the first rotating shaft 5, the driving member 6 is rotatably connected to the first rotating shaft 5, and the driving member 6 is also connected to the pressing member 3. The driving member 6 is disposed opposite to the insertion hole 12. When the box body 1 is assembled in the receiving slot 202 of the printer 200, the driving member 6 is driven to rotate around the first rotating shaft 5 in a direction away from the first inner sidewall 11 by the push rod 203, so as to drive the pressing member 3 to rotate to the loosened position.

[0043] Optionally, the two opposite ends of the first rotating shaft 5 are respectively connected to the first side plate and the second side plate, and the pressing member 3 is connected to the driving member 6, and both the pressing member 3 and the driving member 6 are rotatably connected to the first rotating shaft 5, so that the driving member 6 and the pressing member 3 can rotate synchronously around the first rotating shaft 5.

[0044] When the consumable box 100 is assembled in the receiving slot 202, the push rod 203 can pass through the insertion hole 12 and extend into the box body 1 to contact the drive member 6, so that the push rod 203 can drive the drive member 6 to rotate away from the first inner sidewall 11, thereby the drive member 6 can drive the pressing member 3 to rotate synchronously to the release position, and then the label paper 21 dispensing part 212 can feed paper normally along the paper feeding direction, so that the printer 200 can print the label paper 21.

[0045] When the consumable box 100 is removed from the receiving slot 202, the push rod 203 will be pulled out from the insertion hole 12 and disengage from the drive member 6. Under the drive of the reset member 4, the pressing member 3 can move to the pressing position, thereby pressing the dispensing part 212 of the label paper 21 against the first inner sidewall 11, which can prevent the dispensing part 212 of the label paper 21 from retracting onto the roll 22. By setting the drive member 6 and the first rotating shaft 5, the pressing member 3 can be easily switched between the loose position and the pressing position.

[0046] Please see Figure 4In some embodiments, the driving member 6 and the pressing member 3 are arranged along the axial direction of the first rotating shaft 5, and the driving member 6 is located below the pressing member 3.

[0047] Optionally, with the depth direction of the receiving groove 202 as the vertical direction and the opening of the receiving groove 202 located above the bottom surface of the receiving groove 202, the driving member 6 is positioned below the pressing member 3. When the consumable box 100 is placed in the receiving groove 202, the push rod 203 can be inserted into the box body 1 from below, and the push rod 203 can first contact the driving member 6, thereby facilitating the push rod 203 to drive the driving member 6.

[0048] If the drive unit 6 is positioned above the pressing unit 3, the push rod 203 must be positioned on the cover plate of the printer 200. Since the cover plate is rotatably connected to the main unit of the printer 200, during the process of closing the cover plate, the push rod 203 does not extend into the cartridge 1 along the axial direction of the insertion hole 12, but gradually extends into the cartridge 1 in a direction inclined relative to the insertion axis. In order to facilitate the push rod 203 to extend into the cartridge 1 from the insertion hole 12, the diameter of the insertion hole 12 needs to be designed to be large enough. However, a large diameter insertion hole 12 is prone to dust entering, which may eventually cause dust to fall on the label paper 21, resulting in unclear printing.

[0049] Please see Figure 4 In some embodiments, the consumable box 100 further includes a connecting plate 7, which is rotatably connected to the first rotating shaft 5, and is also connected to the pressing member 3 and the driving member 6.

[0050] Optionally, the connector is provided with a connecting hole, and the first rotating shaft 5 passes through the connecting hole, so that the connector can rotate around the axial direction of the first rotating shaft 5. The pressing member 3 and the driving member 6 are located on the same side of the connector, and the pressing member 3 and the driving member 6 rotate with the connector, so that the connector can drive the pressing member 3 and the driving member 6 to rotate synchronously around the axial direction of the first rotating shaft 5. The connector can increase the structural strength of the pressing member 3 and the driving member 6.

[0051] Please see Figure 9 In some embodiments, the driving member 6 includes an abutment surface 61, which is disposed toward the first inner sidewall 11. The abutment surface 61 is used to abut against the push rod 203 that extends into the housing 1, so as to drive the driving member 6 to rotate away from the first inner sidewall 11 by the push rod 203. When the pressing member 3 is in the pressing position, the orthographic projection of the abutment surface 61 on the first plane is located in the orthographic projection of the hole wall of the insertion hole 12 on the first plane, and the first plane is perpendicular to the axial direction of the insertion hole 12.

[0052] More specifically, after the push rod 203 extends into the housing 1 through the insertion hole 12, the push rod 203 will abut against the contact surface 61 of the drive member 6. As the push rod 203 gradually extends into the housing 1, the push rod 203 will push the drive part away from the first inner sidewall 11, so that the drive part can drive the pressing member 3 to rotate away from the first inner sidewall 11 to the release position.

[0053] When the pressing member 3 is in the pressing position, the orthographic projection of the abutting surface 61 on the first plane is located within the orthographic projection of the hole wall of the insertion hole 12 on the first plane, so that the push rod 203 can directly abut the abutting surface 61 when it extends into the box 1 along the axial direction of the insertion hole 12, and the push rod 203 can easily drive the driving member 6.

[0054] However, if the pressing member 3 is in the pressing position, the orthographic projection of the abutting surface 61 on the first plane is outside the orthographic projection of the hole wall of the insertion hole 12 on the first plane. Therefore, the push rod 203 cannot abut against the abutting surface 61 when it extends into the box 1 along the axial direction of the insertion hole 12. It is necessary to extend the push rod 203 into the box 1 in a direction that is inclined relative to the insertion axis, which will cause the diameter of the insertion hole 12 to become larger.

[0055] In some embodiments, the orthographic projection of the wall of the insertion hole 12 onto the first plane is the first projection, the position closest to the first inner wall 11 on the first projection is the first position, the orthographic projection of the abutting surface 61 onto the first plane is the second projection, and when the pressing member 3 is in the pressing position, the distance between the second projection and the first position along the axis perpendicular to the insertion hole 12 is d, where d satisfies: 2mm≤d≤5mm.

[0056] In this embodiment, the insertion hole 12 is a circular hole, so the outer contour shape of the first projection is circular. The point on the first projection closest to the first inner sidewall 11 is the first position. The abutment surface 61 is a plane that is axially inclined relative to the insertion hole 12, so the outer contour shape of the second projection is square. The pressing member 3 is located in the pressing position. When the push rod 203 extends into the box 1 from the insertion hole 12, at least part of the push rod 203 first extends between the abutment surface 61 and the hole wall of the insertion hole 12. As the push rod 203 gradually extends into the box 1, the push rod 203 will drive the abutment surface 61 away from the first inner sidewall 11.

[0057] When the pressing part 3 is in the pressing position, if d < 2mm, the distance between the abutting surface 61 and the first position is too small, or the diameter of the insertion hole 12 is too small. Since the diameter of the push rod 203 is matched with the diameter of the insertion hole 12, the diameter of the push rod 203 will also be too small, causing the push rod 203 to break easily. If d > 5mm, the distance between the abutting surface 61 and the first position is too large, or the diameter of the insertion hole 12 is too large, causing dust to easily enter the box 1 through the insertion hole 12. Therefore, when d satisfies: 2mm ≤ d ≤ 5mm, the insertion hole 12 is not easy to get dust in, and the push rod 203 will not break easily.

[0058] Please see Figure 9 In some embodiments, the drive member 6 further includes a guide surface 62, which is connected to the abutment surface 61. The abutment surface 61, the guide surface 62, and the insertion hole 12 are arranged sequentially along the axial direction of the insertion hole 12. The guide surface 62 is used to contact the push rod 203 after the push rod 203 is inserted into the insertion hole 12, so as to guide the push rod 203 to abut against the abutment surface 61.

[0059] Optionally, both the guide surface 62 and the abutment surface 61 are planar, and the abutment surface 61 and the guide surface 62 are set at an angle. The guide surface 62 has a first side and a second side arranged opposite to each other along the axial direction of the insertion hole 12. The first side is connected to the abutment surface 61, and the second side is away from the axis of the insertion hole 12 relative to the first side. When the pressing member 3 is in the pressing position, the push rod 203 extends into the box 1 along the axial direction of the insertion hole 12. The first end 82 of the push rod 203 first contacts the second side of the guide surface 62, and as the push rod 203 gradually extends into the box 1, the first end 82 of the push rod 203 moves toward the direction closer to the first side until the first end 82 of the push rod 203 contacts the abutment surface 61. Thus, the guide surface 62 can guide the push rod 203 to move to abut against the abutment surface 61, so that the push rod 203 can push the driving member 6 away from the first inner sidewall 11.

[0060] Please see Figure 6 In some embodiments, the pressing member 3 and the driving member 6 are offset in a direction perpendicular to the axial direction of the first rotating shaft 5, and the pressing member 3 is positioned closer to the first inner sidewall 11 than the driving member 6.

[0061] More specifically, a clearance space can be formed between the directly below the pressing member 3 and the side of the driving member 6 facing the first inner wall 11. After the push rod 203 extends into the box 1 from the insertion hole 12, the push rod 203 is located in the clearance space and pushes the pressing member 3 to the release position, thereby facilitating the insertion of the push rod 203 into the box 1 and reducing the volume occupied by the pressing member 3 and the driving member 6.

[0062] If the driving component 6 and the pressing component 3 are not offset along a direction perpendicular to the first rotating shaft 5, but the driving component 6 is directly below the pressing component 3, then the side of the driving component 6 and the pressing component 3 facing the first inner sidewall 11 will have the aforementioned clearance space. After the push rod 203 extends into the box 1 from the insertion hole 12, the push rod 203 will push both the driving component 6 and the pressing component 3 to the side of the push rod 203 facing away from the first inner sidewall 11. In order for the pressing component 3 to press the label paper 21 against the first inner sidewall 11 when it is in the pressing position, the side of the pressing component 3 facing the first inner sidewall 11 needs to be set closer to the first inner sidewall 11, which will cause the volume of the pressing component 3 to increase, and thus increase the volume of the consumable box 100.

[0063] Please see Figure 3 and Figure 4 In some embodiments, the consumable box 100 further includes a guide plate 8, which is connected inside the box body 1 and extends along the paper feeding direction. The guide plate 8 is used to guide the dispensing part 212 to feed paper along the paper feeding direction. The guide plate 8 has an opening groove 81, which is disposed facing the first inner sidewall 11. When the pressing member 3 is switched to the pressing position, part of the pressing member 3 extends out from the opening groove 81 and presses the dispensing part 212 against the first inner sidewall 11.

[0064] Optionally, the box body 1 is also provided with a paper outlet. The dispensing part 212 moves to the paper outlet along the paper feeding direction and extends out of the box body 1 from the paper outlet. The guide plate 8 is an arc-shaped plate, and one end of the guide plate 8 extends to the paper outlet. The guide plate 8 can guide the dispensing part 212 to feed paper along the paper feeding direction. The guide plate 8 is also provided with an opening groove 81. When the dispensing part 212 feeds paper along the paper feeding direction, the dispensing part 212 will pass through the opening groove 81. When the pressing member 3 switches to the pressing position, the pressing member 3 will extend out from the opening groove 81 and press the dispensing part 212 against the first inner sidewall 11, which can prevent the dispensing part 212 from retracting. By providing an opening groove 81 on the guide plate 8, it is convenient for the pressing member 3 to press the dispensing part 212.

[0065] Please see Figure 5 and Figure 6 In some embodiments, when the pressing member 3 is in the pressing position, the height by which the pressing member 3 protrudes relative to the guide plate 8 toward the first inner sidewall 11 is a1, and a1 satisfies: 1mm≤a1≤3mm.

[0066] More specifically, when the pressing member 3 is in the pressing position, it protrudes a certain distance relative to the guide plate 8 towards the first inner wall 11, pressing the dispensing part 212 against the first inner wall 11. At this time, the dispensing part 212 is lifted by the pressing member 3 and forms an arch. If a1 > 3mm, the distance the dispensing part 212 is lifted by the pressing member 3 will be relatively large, and the size of the arch formed will also be relatively large. When the pressing member 3 switches to the releasing position, the lifted dispensing part 212... It may retract back onto the roll 22, causing the wound portion 211 to unwind, making it impossible to retract the paper during normal printing. If a1 < 1mm, the distance between the first inner sidewall 11 and the guide plate 8 will be too small, affecting the normal paper feeding of the dispensing portion 212. Therefore, when a1 satisfies: 1mm ≤ a ≤ 3mm, it can facilitate the normal paper feeding of the dispensing portion 212, and when the pressing member 3 is switched to the loose position, it can also reduce the occurrence of the dispensing portion 212 retracting back onto the roll 22.

[0067] Please see Figure 7 and Figure 8 In some embodiments, when the pressing member 3 is in the released position, the height by which the pressing member 3 protrudes relative to the guide plate 8 toward the first inner sidewall 11 is a2, and a2 satisfies: 0mm≤a2≤1mm.

[0068] Optionally, when the pressing member 3 is in the released position, the pressing member 3 will be located at the opening slot 81. At this time, the pressing member 3 can guide the dispensing part 212. The pressing member 3 can guide the dispensing part 212 to feed paper in the paper feeding direction. If a2 > 1mm, the pressing member 3 in the released position will lift the dispensing part 212 and form an arch, which will cause the dispensing part 212 to feed paper unevenly. If the pressing member 3 is in the released position, the pressing member 3 is located on the side of the guide plate 8 facing away from the first inner sidewall 11. When the dispensing part 212 feeds paper to the opening slot 81, the pressing member 3 cannot support the dispensing part 212. The dispensing part 212 is prone to paper jam at the opening slot 81, which will cause the dispensing part 212 to feed paper unevenly.

[0069] Please see Figure 7 and Figure 8 In some embodiments, the guide plate 8 includes a first end 82 and a second end 83, which are arranged along the paper feeding direction, and an opening groove 81 is defined between the first end 82 and the second end 83. When the pressing member 3 is in the released position, part of the pressing member 3 is located in the opening groove 81, and the distance between the pressing member 3 and the first end 82 along the paper feeding direction is b1, and the distance between the pressing member 3 and the second end 83 along the paper feeding direction is b2. b1 and b2 satisfy: 5mm≤b1≤9mm, 5mm≤b2≤9mm.

[0070] Optionally, when the pressing member 3 is in the released position, part of the pressing member 3 is located in the opening groove 81, and the pressing member 3 is located in the middle position of the opening groove 81, so that there is a gap between the pressing member 3 and the first end 82 along the paper feeding direction, and there is also a gap between the pressing member 3 and the second end 83 along the paper feeding direction, so that the opening groove 81 has enough space for the pressing member 3 to move toward the first inner sidewall 11, which can facilitate the pressing member 3 to switch from the released position to the pressing position.

[0071] If b1 < 5mm and b2 < 5mm, the distance between the pressing member 3 and the first end 82 along the paper feeding direction is too small, and the distance between the pressing member 3 and the second end 83 along the paper feeding direction is too small. This will cause the pressing member 3 to be unable to move from the opening slot 81 toward the first inner sidewall 11 when switching to the pressing position, which will affect the pressing member 3 from pressing the dispensing part 212 against the first inner sidewall 11.

[0072] If b1 > 9mm and b2 > 9mm, the distance between the pressing member 3 and the first end 82 along the paper feeding direction is too large, and the distance between the pressing member 3 and the second end 83 along the paper feeding direction is too large. When the dispensing part 212 passes through the opening slot 81 along the paper feeding direction, the dispensing part 212 may get stuck between the pressing member 3 and the first end 82, which will affect the normal paper feeding of the dispensing part 212.

[0073] Therefore, when b1 and b2 satisfy: 5mm≤b1≤9mm, 5mm≤b2≤9mm, it is convenient to change the pressing part 3 to the pressing position, and it will not affect the normal paper feeding of the dispensing part 212.

[0074] Please see Figure 4 , Figure 7 as well as Figure 9 In some embodiments, the guide plate 8 includes a first surface 84 located between a first end 82 and a second end 83, and the first surface 84 is connected to the first end 82 and the second end 83 and together defines an opening groove 81. The pressing member 3 includes a second surface 31 disposed opposite to the first surface 84, and the distance between the second surface 31 and the first surface 84 along the direction perpendicular to the paper feed is h, where h satisfies: 0.3mm≤h≤1mm.

[0075] Optionally, the first surface 84 can be a plane, and the first surface 84 is located between the first end 82 and the second end 83. The opposite two sides of the first surface 84 are connected to the first end 82 and the second end 83 respectively, so that the first surface 84, the first end 82 and the second end 83 can surround and define the opening groove 81. The first surface 84 can be the bottom surface of the opening groove 81. The opening groove 81 is a U-shaped groove. The pressing member 3 can extend into the opening groove 81 from the side. The second surface 31 on the pressing member 3 is arranged opposite to the first surface 84.

[0076] If h < 0.3 mm, the second surface 31 and the first surface 84 may rub against each other when the pressing member 3 switches between the pressing and releasing positions, making the switching between the pressing and releasing positions not smooth. If h > 1 mm, the distance between the pressing member 3 and the first surface 84 is too large, requiring the pressing member 3 to be moved upwards, which increases the volume of the consumable box 100. Therefore, when h satisfies 0.3 mm ≤ h ≤ 1 mm, the volume of the consumable box 100 will not increase, and the pressing member 3 can easily switch between the pressing and releasing positions.

[0077] Please see Figure 3 and Figure 4 In some embodiments, the consumable box 100 further includes a partition 9, which is connected to the box body 1, and the winding portion 211 and the pressing member 3 are located on opposite sides of the partition 9.

[0078] Optionally, the partition 9 can be connected to the guide plate 8, and the partition 9 is located between the winding portion 211 and the pressing member 3, so that the partition 9 can separate the winding portion 211 and the pressing member 3, so that when the pressing member 3 switches between the pressing position and the releasing position, the pressing member 3 and the winding portion 211 are always separated by a distance, thereby further reducing the possibility of interference between the pressing member 3 and the winding portion 211.

[0079] Please see Figure 3 and Figure 4 In some embodiments, the consumable box 100 further includes a pressure plate 10 connected to the first inner sidewall 11, and the pressure plate 10 protrudes toward the pressure member 3 to form a convex arc surface 101. When the pressure member 3 is in the pressure position, the pressure member 3 presses the dispensing portion 212 against the convex arc surface 101.

[0080] Optionally, the pressure plate 10 can be configured as an arc-shaped plate, and the pressure plate 10 is connected to the first inner sidewall 11, so that the pressure plate 10 is located between the first inner sidewall 11 and the pressure member 3. The side of the pressure plate 10 facing the pressure member 3 is a convex arc surface 101. When the pressure member 3 switches from the loose position to the pressing position, the pressure member 3 can press the dispensing part 212 against the convex arc surface 101, thereby shortening the distance that the pressure member 3 moves from the loose position to the pressing position, and thus reducing the height of the pressure member 3 protruding relative to the guide plate 8. In this way, the pressure member 3 only needs to lift the dispensing part 212 by a small distance to press the dispensing part 212 against the pressure plate 10, so that when the pressure member 3 switches from the pressing position to the loose position, the length of the dispensing part 212 retracting onto the roll 22 can be reduced.

[0081] Please see Figure 3 , Figure 5 as well as Figure 7In some embodiments, the consumable box 100 includes a ribbon assembly 20, which is movably connected to the box body 1. The ribbon assembly 20 is used to dispense the ribbon 23. When the pressing member 3 switches between the pressing position and the releasing position, the pressing member 3 and the ribbon assembly 20 are spaced apart.

[0082] Optionally, the ribbon assembly 20 can be used to dispense the ribbon 23, and the ribbon 23 can move together with the dispensing part 212 in the paper feed direction, so that the printing roller can press the ribbon 23 and the dispensing part 212 together against the print head. The print head heats the ribbon 23, so that the toner on the ribbon 23 is transferred to the dispensing part 212, thereby completing the printing.

[0083] When the pressing part 3 switches between the pressing position and the releasing position, the pressing part 3 and the ribbon assembly 20 are always kept at a distance, which can prevent interference between the pressing part 3 and the ribbon assembly 20, thereby preventing the pressing part 3 from interfering with normal printing.

[0084] Secondly, please refer to Figure 1 The present application provides a printer 200, which includes a printer body 201, a push rod 203 and a consumable box 100. The printer body 201 has a receiving groove 202, the push rod 203 is disposed in the receiving groove 202 and is connected to the bottom surface of the receiving groove 202, and the consumable box 100 is assembled in the receiving groove 202.

[0085] The beneficial effects of the printer 200 in this embodiment are the same as those of the consumable box 100 in this embodiment, and will not be repeated here.
