A linkage swing arm, a movement and a printer

Abstract

The application provides a linkage swing arm, a movement and a printer, and relates to the technical field of printing equipment. The linkage swing arm comprises a swing arm body and a guide arm connected with each other. The extension direction of the guide arm is perpendicular to the swing plane of the swing arm body. The width direction of the guide arm is obliquely arranged relative to the first edge of the swing arm body to correspond to the swing path of the swing arm body. The first edge is the edge of the swing arm body adjacent to one side of the guide arm. The width direction of the guide arm is obliquely arranged relative to the first edge of the swing arm body. Even if the shape of the swing arm body does not match the swing path, the guide arm is not limited by the shape of the swing arm body, and it can still match the swing path of the swing arm body. In the movement process of the swing arm body, the guide arm can stably guide the swing arm body, avoid the swing arm body from deviating or tilting, and improve the stability of the linkage swing arm. This can make the linkage swing arm respond faster and improve the linkage effect between functional components.

Description

Technical Field

[0001] This application relates to the field of printing equipment technology, and in particular to a linkage swing arm, a mechanism, and a printer. Background Technology

[0002] A wire marking machine is a printer that uses thermal transfer printing technology to print characters on consumables such as sleeves and stickers. In some existing thermal transfer printers, the ribbon cartridge and sleeve are first installed inside the printer. The printer's transmission mechanism drives the new ribbon in the cartridge to align with the consumable, and then the thermal transfer technology quickly and clearly transfers the transfer medium from the ribbon to the surface of the sleeve.

[0003] In related technologies, a linkage arm is installed inside the ribbon cartridge to achieve linkage between the coating head and the cutting mechanism, enabling them to respond to each other and avoid mutual interference during operation. However, the existing linkage arm operates unstably, and its response speed decreases, leading to instability in the relative state between the coating head and the cutting mechanism. Utility Model Content

[0004] The purpose of this application is to provide a linkage swing arm, a mechanism, and a printer to solve or alleviate the aforementioned technical problems existing in the prior art.

[0005] In a first aspect, this application provides a linkage swing arm for a printer. The linkage swing arm includes a connected swing arm body and a guide arm. The extension direction of the guide arm is perpendicular to the swing plane of the swing arm body. The width direction of the guide arm is inclined relative to a first edge of the swing arm body to correspond to the swing path of the swing arm body. The first edge is the edge of the swing arm body adjacent to the guide arm.

[0006] Secondly, this application provides a movement that includes a linked swing arm as described in the first aspect.

[0007] Thirdly, this application provides a printer that includes the mechanism described in the second aspect.

[0008] The technical solution adopted in this application can achieve the following beneficial effects: The linkage arm can coordinate at least two functional components of the printer, including but not limited to the coating head and the cutting mechanism. The linkage arm includes an arm body and a guide arm. The arm body is drively connected to at least two functional components, enabling them to move in unison. The guide arm is connected to the arm body and can cooperate with the printer's carrier to guide the arm body along a preset swing path. The carrier includes, but is not limited to, a mounting plate and the printer housing.

[0009] Compared to related technologies, the guide arm of this application is inclined relative to the first edge of the swing arm body in its width direction. Even if the shape of the swing arm body itself does not match the swing path, the guide arm is not limited by the shape of the swing arm body and can still adapt to the swing path of the swing arm body. For example, the printer carrier has a guide hole that extends along the swing path of the swing arm body. Because the guide arm corresponds to the swing path of the swing arm body, the surface of the guide arm can abut against the wall of the guide hole. This increases the contact area between the guide arm and the hole wall, ensuring stable movement of the guide arm. During the movement of the swing arm body, the guide arm can stably guide the swing arm body, preventing it from shifting or tilting, thus improving the stability of the linked swing arm. This allows the linked swing arm to respond faster and improves the linkage effect between functional components. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0014] In related technologies, a guide structure is often used to improve the stability of the linkage arm. However, the guide structure cannot perfectly adapt to the movement path of the linkage arm. For example, the guide structure can slide with the mounting plate, but due to limitations in the printer's internal space and the structure of the linkage arm, there is only line contact between the guide structure and the mounting plate, resulting in a low fit. The guiding effect of the guide structure also decreases, and the linkage arm still cannot move smoothly. This leads to the linkage arm's movement stability not meeting expectations, and its response speed also decreases, resulting in instability in the relative state between the coating head and the cutting mechanism.

[0015] This application provides a linkage swing arm 110; please refer to [link / reference]. Figure 1 This addresses the aforementioned issues. The linkage arm 110 is applied to printer 1. It should be noted that printer 1 in this application can be a wire marking machine or a barcode printer, etc., and is not limited thereto. However, for ease of understanding, the following description uses a wire marking machine as an example.

[0016] Please see Figure 2 as well as Figure 3The linkage arm 110 can link at least two functional components of the printer 1, including but not limited to the coating head 131 and the cutting mechanism 132. For example, the linkage arm 110 drives the coating head 131 and the cutting mechanism 132. The linkage arm 110 has a first state and a second state. When the linkage arm 110 is in the first state, the cutting mechanism 132 performs a feed operation and cuts the consumable material. The coating head 131 is separated from the consumable material. When the linkage arm 110 is in the second state, the cutting mechanism 132 performs a retraction operation and is separated from the consumable material. The coating head 131 abuts against the surface of the sleeve. The linkage arm 110 enables the linkage between the coating head 131 and the cutting mechanism 132, allowing them to respond to each other and preventing mutual interference during operation. The consumable material includes, but is not limited to, sleeves and stickers.

[0017] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0018] Please continue reading. Figure 1 The linkage arm 110 may include an arm body 111 and a guide arm 112, and the arm body 111 and the guide arm 112 are connected.

[0019] In the embodiments of this application, please refer to Figure 2 The swing arm body 111 is drivenly connected to at least two functional components, enabling the at least two functional components to move in unison; details are not elaborated here. The guide arm 112 is connected to the swing arm body 111. For example, the guide arm 112 can movably engage with the carrier 120 of the printer 1 to guide the swing arm body 111 to move along a preset swing path. The carrier 120 includes, but is not limited to, a mounting plate and a housing.

[0020] Please continue reading. Figure 4The extension direction of the guide arm 112 is perpendicular to the swing plane 1111 of the swing arm body 111. For example, the extension direction of the guide arm 112 can be perpendicular to the swing direction of the swing arm body 111. The guide arm 112 can extend into the guide hole 121, and the wall of the guide hole 121 can restrict the guide arm 112. Through the limiting cooperation between the wall of the guide hole 121 and the guide arm 112, the guide arm 112 can move along the guide hole 121, preventing the swing arm body 111 from easily deviating in the extension direction of the guide arm 112. The swing arm body 111 can only move within the swing plane 1111, thereby effectively improving the activity stability of the swing arm body 111.

[0021] Please continue reading. Figure 3 and Figure 4 The width direction of guide arm 112 (as shown in the figure) Figure 4 (As shown in L2) relative to the first edge 1112 of the swing arm body 111 (the extension direction of the first edge 1112 is as follows) Figure 4 The guide arm 112 (as shown in L1) is inclined to correspond to the swing path of the swing arm body 111, and the first edge 1112 is the edge of the swing arm body 111 adjacent to the guide arm 112. The width direction of the guide arm 112 can be parallel or collinear with the swing plane 1111 of the swing arm body 111. Compared to related technologies, the guide arm 112 of this application is inclined relative to the first edge 1112 of the swing arm body 111. Even if the shape of the swing arm body 111 itself does not match the swing path, the guide arm 112 is not limited by the shape of the swing arm body 111 and can still adapt to the swing path of the swing arm body 111. For example, the carrier 120 of the printer 1 has a guide hole 121. The guide hole 121 can extend along the swing path of the swing arm body 111, and because the guide arm 112 corresponds to the swing path of the swing arm body 111, the surface of the guide arm 112 can abut against the wall of the guide hole 121. This increases the contact area between the guide arm 112 and the hole wall, ensuring that the guide arm 112 can move stably. During the movement of the swing arm body 111, the guide arm 112 can stably guide the swing arm body 111, preventing the swing arm body 111 from deviating or tilting, thus improving the stability of the linkage swing arm 110. This allows the linkage swing arm 110 to respond faster and improves the linkage effect between functional components.

[0022] In some other cases, the surface of the carrier 120 is provided with a guide groove, and the guide arm 112 is movably engaged with the guide groove. The guide groove on the surface of the carrier 120 provides a movement path for the guide arm 112, and the width direction of the guide arm 112 is consistent with the extension direction of the guide groove, so that the guide arm 112 can fit against the guide groove. During the movement of the guide arm 112, the groove wall of the guide groove forms a limit from both sides of the guide arm 112, restricting the guide arm 112 from deviating or wobbling in the width direction, ensuring that the guide arm 112 can only move along the extension direction of the guide groove. Through the guiding and limiting effect of the guide groove, the movement of the guide arm 112 remains stable, effectively improving its movement stability.

[0023] In the embodiments of this application, please refer to Figure 5 The guide arm 112 may include a guide body 1121 and a connecting part 1122. The guide body 1121 and the connecting part 1122 are connected, and the connecting part 1122 is detachably connected to the swing arm body 111. This allows for a detachable connection between the guide arm 112 and the swing arm body 111. Compared to the overall linkage swing arm 110, the smaller guide arm 112 is easier to install independently, avoiding interference from the swing arm body 111 during the installation of the guide arm 112. Furthermore, if the detachably connected guide arm 112 suffers structural damage during operation, maintenance personnel only need to replace the guide arm 112, reducing maintenance costs.

[0024] Please continue reading. Figure 5 The connecting part 1122 is perpendicular to the guide body 1121. The guide body 1121 can restrict the swing arm body 111 in a direction perpendicular to the swing plane 1111 through the connecting part 1122, preventing the swing arm body 111 from deviating in the extension direction of the guide arm 112, so that the swing arm body 111 can only move within the preset swing plane 1111, thereby improving the activity stability of the swing arm body 111.

[0025] In one implementation, please refer to Figure 5 and Figure 6 The connecting part 1122 has a positioning surface 1123, which is aligned with the first edge 1112. The alignment of the positioning surface 1123 with the first edge 1112 provides a positioning function for the engagement of the swing arm body 111 and the connecting part 1122. During assembly, the swing arm body 111 and the connecting part 1122 can form a preset spatial position relationship with the guide body 1121 through the reference function of the positioning surface 1123. This ensures that the extension direction of the guide arm 112 is perpendicular to the swing plane 1111 of the swing arm body 111, eliminating the need for repeated adjustments to the positions of the guide arm 112 and the swing arm body 111, thereby improving assembly efficiency.

[0026] Please see Figure 6The connecting portion 1122 has a notch 1126 that penetrates the positioning surface 1123. The guide body 1121 is connected to the positioning surface 1123. The guide body 1121 is bent relative to the connecting portion 1122 through the notch 1126, so that the width direction of the guide body 1121 is inclined relative to the positioning surface 1123. The notch 1126 of the connecting portion 1122 provides necessary clearance space for the bending of the guide body 1121 relative to the positioning surface 1123, avoiding structural interference between the guide body 1121 and the connecting portion 1122 when bending. This also shortens the distance between the connecting portion 1122 and the guide body 1121, making the structure of the guide arm 112 more compact. The guide body 1121 is connected to the positioning surface 1123, and the clearance space formed by the notch 1126 allows the guide body 1121 to be bent relative to the connecting portion 1122. Furthermore, this arrangement allows the structure of the guide arm 112 to be more compact, while at least ensuring that the inner edge of the guide body 1121 is on the plane of the positioning surface 1123. This edge can abut against the first edge 1112 of the swing arm body 111, ensuring that the positioning surface 1123 and the first edge 1112 can be positioned relative to each other, and the relative positions of the guide arm 112 and the swing arm body 111 are fixed, avoiding positional shifts between the two.

[0027] In the embodiments of this application, please refer to Figure 6 The guide arm 112 may also include a protrusion 1124, which connects to the positioning surface 1123. The protrusion 1124 extends beyond the first edge 1112 and connects to the guide body 1121. Since the guide body 1121 is not confined within the vertical range of the first edge 1112 of the swing arm body 111, the guide arm 112 is not structurally obstructed by the edge of the swing arm body 111, allowing it to be tilted relative to the first edge 1112 of the swing arm body 111. This improves the stability of the linked swing arm 110 and enhances the linkage effect between functional components.

[0028] Please refer again to the embodiments in this application. Figure 2 as well as Figure 3The guide arm 112 is adapted to engage with the carrier 120 of the printer 1 to guide the swing arm body 111 to move along a swing path. For example, the carrier 120 may be a mounting plate with a guide hole 121 into which the guide arm 112 can extend, allowing the guide arm 112 to move along the extension direction of the guide hole 121. The carrier 120 provides a limiting base for the guide arm 112, preventing it from shifting or wobbling during movement and avoiding twisting of the swing arm body 111 that could lead to structural damage. During the movement of the linked swing arm 110, the guide arm 112 can move along a preset swing path, limiting and guiding the swing arm body 111, preventing it from deviating from its predetermined trajectory due to lack of guidance, thus maintaining the stability of the swing arm body 111's movement and effectively improving its reliability.

[0029] Please refer to the previous document. Figure 5 The guide arm 112 is provided with an abutment portion 1125, which abuts against the surface of the carrier 120. Exemplarily, the end of the guide arm 112 away from the swing arm body 111 is bent to form the abutment portion 1125. The abutment portion 1125 may have an abutment surface that abuts against the surface of the carrier 120 along the extending direction of the guide arm 112. The carrier 120 provides support for the guide arm 112, enabling stable movement of the guide arm 112 and ensuring that the direction of movement of the guide arm 112 is parallel or overlaps with the swing plane 1111 of the swing arm body 111. The guide arm 112 transfers the weight of the swing arm body 111 to the carrier 120, preventing the swing arm body 111 from being damaged by excessive bending loads.

[0030] In one implementation, please refer to Figure 7 and Figure 8The abutment portion 1125 includes at least a first abutment portion 1125a and a second abutment portion 1125b. Exemplarily, the number of abutment portions 1125 can be at least two, such as two, three, or more, and is not limited thereto. The first abutment portion 1125a and the second abutment portion 1125b are spaced apart along the extending direction of the guide arm 112. The first abutment portion 1125a and the second abutment portion 1125b are respectively located on opposite sides of the carrier 120. Exemplarily, multiple portions on the guide arm 112 are bent to form the first abutment portion 1125a and the second abutment portion 1125b, which abut against opposite surfaces of the carrier 120. During the movement of the guide arm 112 relative to the carrier 120, the first abutting part 1125a and the second abutting part 1125b can jointly apply abutting force to the carrier 120. The carrier 120 can limit the guide arm 112, that is, the carrier 120 restricts the guide arm 112, so that the guide arm 112 can move according to the swing path of the swing arm body 111, preventing the guide arm 112 from tilting or sinking in its own extension direction, avoiding uneven force or shaking caused by the difference in abutting effect between the carrier 120 and the guide arm 112, and thus ensuring the stability of the movement of the guide arm 112 by stably abutting the carrier 120.

[0031] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0032] Preferably, please refer to Figure 8The first abutting portion 1125a and the second abutting portion 1125b are located on the same side of the guide body 1121 and are spaced apart along the extending direction of the guide body 1121. On the same side of the guide body 1121, the first abutting portion 1125a and the second abutting portion 1125b respectively abut against two opposite surfaces of the carrier 120. For example, the guide body 1121 may be a strip-shaped structure, and the carrier 120 has a guide hole 121, into which the guide body 1121 can extend. The first abutting portion 1125a and the second abutting portion 1125b are distributed on opposite sides of the wall of the guide hole 121. This configuration allows the first abutment portion 1125a and the second abutment portion 1125b on the same side to apply limiting abutment forces to the main body from the opposite sides of the guide arm 112, respectively, to prevent the guide body 1121 from shifting or misaligning along the extension direction of the guide arm 112 when tilted, and to ensure that the guide body 1121 and the carrier 120 maintain a stable positional relationship even when the printer 1 vibrates or is bumped, thus ensuring the stability of the guide arm 112's movement.

[0033] Of course, in some other cases, in addition to the guide arm 112, other parts of the swing arm body 111 are provided with other guide structures. Other guide structures can also be movably matched with the carrier 120. The structure of other guide structures can be the same as or different from the structure of the guide arm 112. For example, other guide structures can be mounting columns, sliders, etc., to further improve the activity stability of the swing arm body 111. These will not be listed or described in detail here.

[0034] This application also provides a movement 100; please refer to the previous section. Figure 2 The movement 100 may include the linkage arm 110 as described above.

[0035] In the embodiments of this application, please continue to refer to Figure 2 The mechanism 100 may also include a carrier 120, which may be the casing or mounting plate of the printer 1, and is not limited thereto. In one embodiment, the carrier 120 has a guide hole 121, and the width direction of the guide arm 112 is in the same direction as the extension direction of the guide hole 121. For example, the guide hole 121 may be a strip-shaped hole that can extend along a preset swing path of the swing arm body 111. For example, the surface of the carrier 120 may be provided with a rotating shaft 122, and the swing arm body 111 may be rotatably connected to the rotating shaft 122, so that the swing arm body 111 can rotate around the rotating shaft 122. The extension direction of the strip-shaped hole may be arc-shaped to adapt to the path of the rotating shaft 122.

[0036] The guide arm 112 extends into the guide hole 121, and the guide arm 112 is movably engaged with the wall of the guide hole 121. The guide arm 112 and the wall of the guide hole 121 form a movable engagement, and the surface of the guide arm 112 can abut against the wall of the guide hole 121. The wall of the guide hole 121 can limit the guide arm 112 from both sides, restricting its offset or swaying in a first direction. This first direction intersects the width direction of the guide arm 112. This allows the guide arm 112 to move stably along the extension direction of the guide hole 121, ensuring a stable trajectory and effectively improving the stability of the linkage swing arm 110.

[0037] For further details, please refer to Figure 9 The guide hole 121 has a first section 1211 and a second section 1212 that are interconnected. The wall of the first section 1211 can abut against the guide arm 112 to support the swing arm body 111. The width of the second section 1212 is greater than that of the first section 1211, and the second section 1212 can pass through the abutment portion 1125 of the guide arm 112. This avoids the wall of the second section 1212 from obstructing the disassembly or installation of the abutment portion 1125, thereby improving the installation effect of the guide arm 112. This will not be described in detail here.

[0038] In some other cases, the surface of the carrier 120 is provided with a guide groove, and the guide arm 112 is movably engaged with the guide groove. Alternatively, the guide arm 112 abuts against and is movably engaged with the side of the carrier 120, and the side of the carrier 120 guides the guide arm 112 to move along a preset movement path to improve the movement stability of the guide arm 112, which will not be described in detail.

[0039] This application also provides a printer 1, please refer to... Figure 10 The printer 1 may include the mechanism 100 as described above. The printer 1 in this application may be a wire marking machine or a barcode printer, etc., and is not limited thereto.

[0040] Furthermore, it should be noted that the scope of the methods and apparatus in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in the reverse order, depending on the functions involved. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. In addition, features described with reference to certain examples may be combined in other examples.

[0041] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto.
