Description

Technical Field

[0001] This utility model relates to the field of imaging technology, specifically to a printer and its driving components. Background Technology

[0002] Imaging devices such as printers inevitably require drive components to move the printhead assembly, paper pressure shaft assembly, and other structures. Drive components generally include motors and other driving parts, as well as positioning seats for mounting the drive components. To secure the drive components and reduce vibration, the ends of the drive components often have positioning parts, and the positioning seats correspondingly have positioning holes for positioning and engaging the positioning parts. When installing the drive component, the end of the drive component's output shaft must first be inserted axially into the positioning hole, and then the drive component must be pushed axially until the positioning part is properly engaged in the positioning hole. When disassembling the drive component, it must first be pushed axially in the opposite direction until the end of the output shaft disengages from the positioning hole before the drive component can be removed. This structure not only makes it inconvenient for operators to install and disassemble the drive component, but also, because the output shaft of the drive component often requires the installation of gears or pulleys for power transmission, the output shaft often has a certain length. This necessitates sufficient lateral space within the printer for the axial movement of the drive component during installation and disassembly, increasing the printer's lateral dimensions and cost. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a drive component that is easy for operators to disassemble and assemble, saves the horizontal space of the printer, makes the printer structure more compact, and reduces the cost of the printer.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: a driving component, including a driving member and a positioning seat for positioning and installing the driving member, the driving member including a main body and an output shaft rotatably connected to the main body, the main body having a positioning part, the positioning seat including a positioning plate, the positioning plate having a positioning hole for positioning and connecting the positioning part, the top of the positioning plate having a mounting groove that allows the output shaft to pass through, the mounting groove extending from the top of the positioning plate to the positioning hole.

[0005] Compared to existing technologies, the advantages of this invention are as follows: This drive assembly has a through-groove extending from the top of the positioning plate to the positioning hole. During installation, the output shaft of the drive component is first driven downwards through the through-groove and into the positioning hole. Then, the drive component is pushed axially until its positioning part is inserted into the positioning hole, thus positioning and installing the drive component onto the positioning seat. This eliminates the need to insert the end of the output shaft axially into the positioning hole before pushing the drive component axially to insert the positioning part. During disassembly, the drive component is first pushed axially in the opposite direction until its positioning part disengages from the positioning hole. Then, the drive component is lifted upwards so that the output shaft passes upwards through the through-groove, allowing the drive component to be removed from the positioning seat. This eliminates the need to push the drive component axially in the opposite direction until the end of the output shaft disengages from the positioning hole before removing the drive component from the positioning seat. Therefore, this drive assembly facilitates disassembly and assembly by operators, saves lateral space in the printer, makes the printer structure more compact, and reduces printer costs.

[0006] In the aforementioned drive assembly, the width of the mounting slot is approximately equal to the diameter of the output shaft.

[0007] In the aforementioned drive assembly, both sides of the mounting slot are provided with guide slopes.

[0008] The aforementioned drive assembly further includes a drive shaft, a drive wheel, and a driven wheel. The drive shaft is rotatably connected to the positioning plate. The drive wheel and the driven wheel are respectively fixedly connected to the output shaft and the drive shaft. The drive wheel is directly or indirectly connected to the driven wheel to drive the driven wheel to rotate with the drive shaft.

[0009] The aforementioned drive assembly also includes a belt, with the two ends of the belt connected to the driving pulley and the driven pulley, respectively.

[0010] In the aforementioned drive assembly, the driving pulley is a driving pulley, the driven pulley is a driven pulley, the belt is a synchronous belt, and the two ends of the synchronous belt are respectively engaged with the driving pulley and the driven pulley.

[0011] The aforementioned drive assembly also includes a tensioning wheel, which is rotatably connected to the positioning plate and abuts against the outer side of the belt.

[0012] In the aforementioned drive assembly, the outer wall of the tension wheel is provided with an annular groove along the circumference, and the bottom wall of the annular groove abuts against the outer side of the belt.

[0013] In the aforementioned drive assembly, the width of the annular groove is greater than the width of the belt.

[0014] This invention also provides a printer that includes the aforementioned drive component. Since the printer uses the aforementioned drive component, it has at least all the beneficial effects that the aforementioned drive component can bring.

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 3 An embodiment of this utility model provides a drive assembly, including a drive component 100 and a positioning seat 200 for positioning and mounting the drive component 100. The drive component 100 may be a drive structure such as a drive motor, including a main body 110 and an output shaft 120 rotatably connected to the main body 110. The main body 110 has a positioning part 111. The positioning seat 200 includes a positioning plate 210. The positioning plate 210 has a positioning hole 211 for positioning and connecting the positioning part 111. The top of the positioning plate 210 has a mounting groove 212 that allows the output shaft 120 to pass through. The mounting groove 212 extends from the top of the positioning plate 210 to the positioning hole 211.

[0019] This drive assembly has a mounting groove 212 extending through to the positioning hole 211 at the top of the positioning plate 210. During installation, the output shaft 120 of the drive member 100 is first pushed downward through the mounting groove 212 and into the positioning hole 211. Then, the drive member 100 is pushed axially so that the positioning part 111 of the drive member 100 is positioned and inserted into the positioning hole 211. This allows the drive member 100 to be positioned and installed on the positioning seat 200 without needing to insert the end of the output shaft 120 axially into the positioning hole 211 before continuing to push the drive member 100 axially. The actuator 100 positions the positioning part 111 into the positioning hole 211. During disassembly, the actuator 100 is first pushed axially in the opposite direction to disengage the positioning part 111 from the positioning hole 211. Then, the actuator 100 is lifted upwards so that the output shaft 120 passes upwards through the mounting slot 212, allowing the actuator 100 to be removed from the positioning seat 200. This eliminates the need to push the actuator 100 axially in the opposite direction until the end of the output shaft 120 disengages from the positioning hole 211 before removing it from the positioning seat 200. Therefore, this drive assembly is easy for operators to assemble and disassemble, saves lateral space in the printer, makes the printer structure more compact, and reduces printer costs. Furthermore, when disassembling the drive assembly, it is not necessary to remove gears or other structures on the output shaft 120. During transportation, some parts of the drive assembly can be pre-assembled, facilitating packaging and transportation and further improving the convenience for consumers to assemble and disassemble the drive assembly.

[0020] Reference Figure 2In some embodiments, the positioning base 200 further includes a mounting plate 220. The mounting plate 220 and the positioning upright plate 210 are integrally formed and arranged in an "L" shape. When the drive assembly is installed into the printer, the mounting plate 220 can be installed in a preset position inside the printer and fixed with screws or other structures. Further, the width of the mounting groove 212 is approximately equal to the diameter of the output shaft 120, and the width of the mounting groove 212 is slightly larger than the diameter of the output shaft 120, for example, 1mm to 2mm larger, so that the output shaft 120 can pass through the mounting groove 212. Since the presence of the mounting groove 212 will cause a notch to be formed on the side of the positioning hole 211, and the width of the mounting groove 212 is set to be approximately equal to the diameter of the output shaft 120, the notch on the side of the positioning hole 211 will not be too large, and the positioning effect of the positioning hole 211 on the positioning part 111 will not be affected. Furthermore, both sides of the groove opening of the mounting groove 212 are provided with guide slopes 2121 to facilitate the alignment of the output shaft 120 and its smooth entry into the mounting groove 212. Specifically, the guide slopes 2121 are located on the upper part of the two sides of the groove opening of the mounting groove 212, while the lower part of the two sides of the groove opening of the mounting groove 212 is transitionally connected to the wall of the positioning hole 211. Therefore, it is not necessary to add additional guide slopes to provide guidance for the output shaft 120 to enter the mounting groove 212. In other words, the transitional connection between the side wall of the mounting groove 212 and the wall of the positioning hole 211 can serve as a guide slope.

[0021] Reference Figure 1 The drive assembly of this utility model further includes a transmission shaft 300, a driving wheel 400, and a driven wheel 500. The transmission shaft 300 is rotatably connected to the positioning plate 210. The driving wheel 400 and the driven wheel 500 are respectively fixedly connected to the output shaft 120 and the transmission shaft 300. The driving wheel 400 is directly or indirectly connected to the driven wheel 500. The printer's printhead assembly, paper pressure shaft assembly, and other structures can be connected to the transmission shaft 300. When the drive unit 100 is started, the driving wheel 400 begins to rotate, thereby driving the driven wheel 500 to rotate together with the transmission shaft 300, so as to transmit power to the printhead assembly, paper pressure shaft assembly, and other structures. When the drive assembly is used to drive the paper pressure shaft assembly, the transmission shaft 300 can directly be the paper pressure shaft.

[0022] In some embodiments, both the driving gear 400 and the driven gear 500 are gears, and they can be directly meshed together, or they can be respectively meshed with intermediate transmission gears to achieve power transmission. In other embodiments, refer to... Figure 1 and Figure 2Both the driving pulley 400 and the driven pulley 500 are pulleys, connected by a belt 600. Further, the driving pulley 400 is a driving pulley, the driven pulley 500 is a driven pulley, and the belt 600 is a synchronous belt, with its two ends meshing with the driving pulley and the driven pulley, respectively. Further, a tensioning pulley 700 is also provided on the positioning plate 210, rotatably connected to the positioning plate 210, and abutting against the outer side of the belt 600 to provide tension to the belt 600. Further, refer to... Figure 3 The outer wall of the tensioning pulley 700 is provided with an annular groove 710 along the circumference. The width of the annular groove 710 is greater than the width of the belt 600. The bottom wall of the annular groove 710 abuts against the outer side of the belt 600. While providing tension, it can also provide a certain limit to reduce the lateral vibration of the synchronous belt. At the same time, it ensures that there is sufficient contact area between the tensioning pulley 700 and the synchronous belt. The contact width is equal to the width of the synchronous belt to ensure the tensioning effect. Furthermore, the tensioning wheel 700 is rotatably connected to the positioning plate 210 via the rotating shaft 800. Alternatively, the rotating shaft 800 can be rotatably connected to the positioning plate 210, while the tensioning wheel 700 is fixedly connected to the rotating shaft 800. Or, the rotating shaft 800 can be fixedly connected to the positioning plate 210, while the tensioning wheel 700 is rotatably connected to the rotating shaft 800. As long as the tensioning wheel 700 is allowed to rotate, it is acceptable. During the operation of the belt 600, the tensioning wheel 700 can also rotate relative to the positioning plate 210, thereby achieving tension while reducing friction with the belt 600.

[0023] An embodiment of this utility model also provides a printer including the aforementioned drive component. Since the printer uses the aforementioned drive component, the printer has at least all the beneficial effects that the aforementioned drive component can bring.
