Description

Technical Field

[0001] This application relates to the field of printer technology, and more particularly to a lifting device and a printer. Background Technology

[0002] Temporary license plates for vehicles typically require thermal transfer printing. Simply put, thermal transfer printing uses a special ribbon, similar to a fax machine printhead, to transfer the toner coating from the ribbon onto paper or other materials through heating. When printing license plates using a thermal transfer printer, the ribbon is positioned between the printing roller and the object being printed by a conveyor roller and a return roller. Then, a pressing component brings the coated surface of the ribbon into contact with the license plate surface. The heating element of the printhead heats up, transferring the dye from the ribbon's coating onto the temporary license plate, completing the printing process.

[0003] The space occupied by the printhead lifting structure in existing printers is relatively large, which makes it difficult to meet the space design requirements of printers in the industrial field. Utility Model Content

[0004] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a lifting device and a printer.

[0005] This application provides the following technical solution: a lifting device having intersecting first and second directions, comprising:

[0006] Shaft;

[0007] A connector, one end of which is connected to the rotating shaft along the first direction, is rotatable about the axis of the rotating shaft;

[0008] The printhead is located at the end of the connector away from the rotating shaft;

[0009] An eccentric wheel is disposed at one end of the connector near the print head, and the eccentric wheel is connected to the connector in a driving manner.

[0010] A printing roller is disposed along the second direction on the side of the print head facing the eccentric wheel;

[0011] During the rotation of the eccentric wheel, the print head has a raised position and a printing position along the second direction;

[0012] In the raised position, the print head is spaced apart from the print roller along the second direction;

[0013] At the printing position, the print head abuts against the print roller along the second direction.

[0014] In some embodiments, the connector includes a mounting bracket and a mounting plate, the mounting plate being disposed on one side of the mounting bracket along the second direction, and the printhead being disposed on the side of the mounting plate opposite to the mounting bracket.

[0015] In some embodiments, the lifting device further has a third direction that intersects the first direction and the second direction in pairs;

[0016] The mounting bracket includes a support plate and a connecting plate, wherein the connecting plate is provided on two opposite sides of the support plate along the third direction;

[0017] The connecting plate is provided with a transmission component on one side along the third direction, and the transmission component is connected to the eccentric wheel via a transmission.

[0018] In some embodiments, the eccentric wheel is disposed on the side of the transmission member away from the support plate along the second direction, and there is a gap between the eccentric wheel and the printing roller.

[0019] In some embodiments, the transmission element is a bearing or a pulley.

[0020] In some embodiments, a first connecting rod is provided between the two transmission components, and the first connecting rod and the transmission component are coaxially connected.

This not only simplifies the overall structure of the lifting device, but also improves the efficiency and convenience of switching between lifting and lowering the print head, reduces the transportation and installation costs of the lifting device, thereby reducing the space occupied by the lifting device in the printer, improving the space utilization of the printer, reducing the overall size of the printer, and saving space.

The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] like Figures 1 to 3As described above, some embodiments of this application provide a lifting device having intersecting first direction X and second direction Y. This device is mainly used to improve the efficiency of the lifting device during lifting and lowering, simplify the structure of the lifting device, improve the space utilization of the lifting device, reduce the transportation and installation costs of the lifting device, thereby reducing the space occupied by the lifting device in the printer, improving the space utilization of the printer, reducing the overall size of the printer, saving space, and also improving the overall aesthetics.

[0040] The lifting device includes a rotating shaft 100, a connecting piece 200, a print head 300, an eccentric wheel 400, and a print roller 500.

[0041] One end of the connector 200 along the first direction X is connected to the rotating shaft 100. The connection method between the connector 200 and the rotating shaft 100 includes any one of snap-fit, threaded connection, bolt connection, and rotatable connection, which can be specifically set according to the actual situation.

[0042] It is understood that by connecting the connector 200 and the rotating shaft 100, the connector 200 is able to rotate about the axis of the rotating shaft 100.

[0043] In this embodiment, the first direction X is the length direction of the connector 200.

[0044] The print head 300 is located at the end of the connector 200 away from the rotating shaft 100. That is, when the connector 200 rotates along the axis of the rotating shaft 100, it can drive the print head 300 to rotate synchronously, so as to adjust the distance of the print head 300 relative to the printing roller 500.

[0045] It should be noted that when the print head 300 is in contact with the print roller 500, the print head 300 and the print roller 500 can limit the license plate, thus allowing the print head 300 to print the license plate. Additionally, when the print head 300 and the print roller 500 are spaced apart, the printed license plate can move away from the print head 300 under the driving force of the print roller 500.

[0046] In this embodiment, the eccentric wheel 400 is disposed at one end of the connector 200 near the print head 300, and the eccentric wheel 400 is connected to the connector 200 in a transmission manner, so that the print head 300 is lifted or lowered during the rotation of the eccentric wheel 400. By placing the eccentric wheel 400 adjacent to the print head 300, the transmission distance between the eccentric wheel 400 and the print head 300 is reduced, thereby improving the space utilization of the lifting device.

[0047] It is understandable that by aligning the eccentric wheel 400 adjacent to the print head 300, the length of the lifting device along the first direction X is reduced. By connecting the eccentric wheel 400 and the connector 200, the eccentric wheel 400 can drive the print head 300 to rotate synchronously during rotation, thereby achieving the lifting or lowering of the print head 300. This not only simplifies the lifting structure of the print head 300, but also improves the efficiency and convenience of switching between lifting and lowering the print head 300.

[0048] In some embodiments, the connection between the eccentric wheel 400 and the connector 200 includes a rotating connection or a sliding connection, so as to ensure the smoothness and stability of the transmission between the eccentric wheel 400 and the connector 200 during rotation, reduce the friction between the eccentric wheel 400 and the connector 200, reduce resistance, and improve the service life of the eccentric wheel 400 and the connector 200.

[0049] Furthermore, the print roller 500 is positioned along the second direction Y on the side of the print head 300 facing the eccentric wheel 400. It is understood that the print roller 500 and the print head 300 are positioned opposite each other along the second direction Y, with the print roller 500 adjacent to the eccentric wheel 400, to reduce the distance between the print roller 500 and the eccentric wheel 400. This improves the space utilization of the print roller 500 and the eccentric wheel 400 in the lifting device, effectively reducing the length of the lifting device along the first direction X, improving the compactness of the lifting device, and enabling it to adapt to various types of printers, thus increasing the utilization rate of the lifting device.

[0050] It should be noted that, in this embodiment, during the rotation of the eccentric wheel 400, the print head 300 has a lifting position and a printing position along the second direction Y. That is, during the rotation of the eccentric wheel 400, the print head 300 can switch between the lifting position and the printing position to achieve the purpose of printing and transmitting license plates.

[0051] In the raised position, the print head 300 is spaced apart from the print roller 500 along the second direction Y. That is, at this time, the distance between the print head 300 and the print roller 500 is the largest, so that the license plate after printing can move away from the print head 300 under the transmission action of the print roller 500, thereby realizing the printing and transmission of the license plate.

[0052] Additionally, at the printing position, the print head 300 abuts against the print roller 500 along the second direction Y. At this time, the print head 300 and the print roller 500 can limit the license plate, that is, the license plate is located between the print head 300 and the print roller 500.

[0053] In this embodiment, the printing position is the position after the print head 300 descends. That is, when the print head 300 is in the printing position, it can limit the license plate, and at the same time, the print head 300 can print the license plate.

[0054] It should be noted that in this embodiment, the second direction Y is the vertical direction.

[0055] In addition, by shortening the length of the lifting device along the first direction X, the length of the ribbon can be reduced, thereby lowering the printing cost of the lifting device.

[0056] like Figure 1 As shown, in some embodiments of this application, the connector 200 includes a mounting bracket 210 and a mounting plate 220. The mounting plate 220 is disposed on one side of the mounting bracket 210 along the second direction Y. The connection method between the mounting bracket 210 and the mounting plate 220 includes any one of threaded connection, snap-fit, adhesive, welding, and bolt connection, which can be specifically set according to the actual situation.

[0057] The print head 300 is disposed on the side of the mounting plate 220 away from the mounting bracket 210, so as to fix the print head 300 on the mounting bracket 210 through the mounting plate 220, thereby ensuring the stability of the print head 300 on the mounting bracket 210.

[0058] In addition, the connection method between the printhead 300 and the mounting plate 220 includes any one of the following: threaded connection, snap-fit, adhesive connection, welding, or bolted connection, which can be specifically set according to the actual situation.

[0059] In some embodiments, the printhead 300 and the mounting plate 220 are connected in a detachable manner to ensure the efficiency of installation or removal between the printhead 300 and the mounting plate 220, so as to facilitate cleaning, maintenance or replacement.

[0060] In this embodiment, the mounting bracket 210 defines an installation space along one side of the first direction X. The mounting plate 220 and the print head 300 are respectively housed in the installation space and connected to the mounting bracket 210 to improve the compactness of the connection structure between the print head 300 and the connector 200 and further improve space utilization.

[0061] like Figure 1 As shown, in some embodiments of this application, the lifting device further has a third direction Z that intersects the first direction X and the second direction Y in pairs.

[0062] The mounting frame 210 includes a support plate 211 and a connecting plate 212. The support plate 211 has the connecting plate 212 on two opposite sides along the third direction Z. The connecting plate 212 and the support plate 211 are integrally formed to improve the overall strength and stability of the mounting frame 210.

[0063] In some embodiments, the two connecting plates 212 are parallel to each other and are symmetrically arranged on opposite sides of the support plate 211.

[0064] In addition, the connecting plate 212 is provided with a transmission member 600 on one side along the third direction Z, and the transmission member 600 is connected to the eccentric wheel 400 for transmission. During the rotation of the eccentric wheel 400, the transmission member 600 is driven to move along the first direction X, thereby driving the mounting frame 210 to move along the first direction X, and driving the print head 300 to move along the first direction X through the mounting frame 210, thereby controlling the print head 300 to switch between the lifting position and the printing position.

[0065] It is understood that in some embodiments, the transmission component 600 is disposed on the side of the connecting plate 212 facing the print head 300; in other embodiments, the transmission component 600 is disposed on the side of the connecting plate 212 away from the print head 300, and can be specifically set according to the actual situation.

[0066] like Figure 1 and Figure 3 As shown, in some embodiments of this application, the eccentric wheel 400 is disposed on the side of the transmission member 600 away from the support plate 211 along the second direction Y. The eccentric wheel 400 is close to the printing roller 500, and there is a gap between the eccentric wheel 400 and the printing roller 500 to avoid the eccentric wheel 400 from contacting the printing roller 500 during rotation, so as to ensure the stability and smoothness of the printing roller 500 and the eccentric wheel 400 during rotation.

[0067] like Figure 1 and Figure 3 As shown, in some embodiments of this application, the transmission component 600 is a bearing or a pulley, so that the eccentric wheel 400 can drive the transmission component 600 to rotate during the rotation, thereby reducing the friction between the transmission component 600 and the eccentric wheel 400, and improving the smoothness and stability of the print head 300 during the lifting or lowering process along the second direction Y.

[0068] like Figure 1 As shown, in some embodiments of this application, a first connecting rod 700 is provided between the two transmission components 600. The first connecting rod 700 and the transmission component 600 are coaxially connected so that during the rotation of the eccentric wheel 400, the transmission component 600 can be driven to rotate and the mounting frame 210 and the print head 300 can be driven to rise or fall along the second direction Y through the first connecting rod 700, so as to ensure the stability and smoothness of the print head 300 during the rising or falling process.

[0069] like Figure 1As shown, in some embodiments of this application, along the third direction Z, the eccentric wheels 400 are respectively provided on two opposite sides of the connector 200.

[0070] In addition, a second connecting rod 800 is provided between the two eccentric wheels 400. The second connecting rod 800 and the eccentric wheels 400 are coaxially connected, that is, one end of the second connecting rod 800 is coaxially connected to one of the eccentric wheels 400, and the other end of the second connecting rod 800 is coaxially connected to the other eccentric wheel 400.

[0071] In this embodiment, two eccentric wheels 400 are symmetrically arranged at both ends of the second connecting rod 800 to ensure that the other two eccentric wheels 400 rotate synchronously, thereby further improving the stability and smoothness of the print head 300 during the lifting or lowering process.

[0072] It should be noted that the lifting device also includes a drive motor, the output end of which is connected to at least one eccentric wheel 400 so that during the process of the drive motor controlling the rotation of the eccentric wheel 400, another eccentric wheel 400 is driven to rotate synchronously through the second connecting rod 800, thereby controlling the lifting or lowering of the connecting piece 200 and the print head 300.

[0073] In some embodiments of this application, the axis of the first connecting rod 700, the axis of the second connecting rod 800, and the axis of the rotating shaft 100 are parallel.

[0074] In some embodiments of this application, the lifting device further includes a drive member (not shown in the figure), which is connected to the printing roller 500 to drive the printing roller 500 to rotate about its own axis.

[0075] Along the third direction Z, one end of the printing roller 500 is provided with a driven gear, and the output end of the drive member is provided with a driving gear. The driving gear and the driven gear mesh so that during the operation of the drive member, the driving gear is driven to rotate coaxially with the output end of the drive member, and the driven gear is driven to rotate through the driving gear, thereby driving the printing roller 500 to rotate through the driven gear.

[0076] Some embodiments of this application provide a printer that includes the lifting device described in any of the foregoing embodiments.

[0077] It should be noted that the printer provided in this embodiment has the structure of the lifting device described in any of the above embodiments and the beneficial effects thereof, which will not be elaborated here.

[0078] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0079] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0080] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
