Description

Technical Field

[0001] This invention relates to the field of printing equipment technology, and in particular to a printer. Background Technology

[0002] In related technologies, to facilitate customer operation, industrial printer components are typically fixed to one side of a large board, with the other side suspended. While this structure offers operational convenience, it places high demands on the components: because the assembly is in a cantilever beam configuration, misalignment is prone to occur. In printer design, the rollers are perpendicular to the main body of the printer board, and the paper path is parallel to the board. As a crucial component, the perpendicularity of the rollers directly affects print quality and accuracy. However, due to manufacturing limitations, the flatness of the main board, and the cumulative tolerances of multiple component assembly, it is difficult for the assembled rollers to be perfectly perpendicular to the main board. For labels containing delicate components, which are small, contain a lot of information, and require multiple labels per row, the perpendicularity of the rollers is critical. Furthermore, due to current manufacturing limitations, some manufacturers' label sizes are not very precise; even a slight misalignment of the label will result in misaligned printed content, affecting print quality.

[0035] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0037] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0038] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0039] In related technologies, refer to Figure 1 To facilitate customer operation, industrial printer components are typically fixed to one side of a large printing plate, with the other side suspended. While this structure offers operational convenience, it places high demands on the components: because the assembly is in a cantilever beam configuration, misalignment is prone to occur. In printer design, the rubber roller is perpendicular to the main printing plate, and the paper path is parallel to the plate. As a crucial component, the perpendicularity of the rubber roller directly affects print quality and accuracy. However, due to manufacturing limitations, the flatness of the main printing plate, and the cumulative tolerances of multiple component assembly, it is difficult for the assembled rubber roller to be perfectly perpendicular to the main printing plate. For labels containing delicate components, which are small, contain a lot of information, and require multiple labels per row, the perpendicularity of the rubber roller is critical. Furthermore, due to current manufacturing limitations, some manufacturers' label sizes are not perfectly precise; even a slight misalignment of the label will result in misaligned printed content, affecting print quality.

[0040] Therefore, this invention proposes a printer with adjustable roller position to improve print quality.

[0041] Reference Figures 2 to 7 This invention discloses a printer, which can be an industrial printer or other types of printers. Specifically, the printer includes a base 100, a printing support assembly, and a roller assembly 300. The base 100 is provided with a mounting plate 110, which is generally vertically placed. The printing support assembly is mounted on the mounting plate 110 and is provided with a printing support plate. One end of the roller assembly 300 is connected to the mounting plate 110, and the other end is connected to the printing support plate. The printing support plate includes a fixed plate 250 and a movable plate, with the movable plate movably mounted on the fixed plate 250. One end of the roller assembly 300 is mounted on the movable plate.

[0042] Since the movable plate of the printer of the present invention is movably mounted on the fixed plate 250, and one end of the rubber roller assembly 300 is mounted on the movable plate, when the position between the rubber roller assembly 300 and the mounting plate 110 needs to be adjusted, the movable plate can be adjusted so that the rubber roller assembly 300 can be moved to a suitable position, thereby improving the printing quality.

[0043] Reference Figure 3 and Figure 4 It is understood that in some embodiments of the present invention, the movable plate is provided with a guide block 212, and the fixed plate 250 is provided with a guide groove 251. The guide block 212 is slidably installed in the guide groove 251, so that when the movable plate is adjusted, the movable plate can move along the guide groove 251 through the guide block 212, thereby limiting the direction of movement of the movable plate, which is beneficial to improving the accuracy of the position adjustment of the rubber roller assembly 300, and at the same time reducing the shaking amplitude of the rubber roller assembly 300 during the adjustment process. Specifically, the setting direction of the guide groove 251 can be vertical, horizontal, or inclined at an angle to the vertical, so that the movable plate can be moved along the vertical, horizontal, or inclined direction at an angle to the vertical to adjust its position as needed. Of course, there can be multiple guide blocks 212, thereby further improving the stability of the movement of the movable plate. For example, in some embodiments, there are two guide blocks 212 and two guide grooves 251, with the two guide blocks 212 slidably installed in the corresponding guide grooves 251.

[0044] Reference Figure 2 and Figure 3It is understood that, in order to facilitate user adjustment of the movable plate, in some embodiments of the present invention, the printing support assembly further includes a first adjusting block 230. The movable plate is provided with a first adjusting hole 211, and the first adjusting block 230 passes through the first adjusting hole 211 and is connected to the fixed plate 250. The first adjusting block 230 can push the movable plate to move along the guide groove 251. When the user needs to adjust the position of the movable plate, by rotating the first adjusting block 230, the first adjusting block 230 moves within the first adjusting hole 211, thereby pushing the movable plate to move, making the operation more convenient.

[0045] Reference Figure 2 and Figure 7 It should be noted that the printing support assembly is also equipped with a first bolt 260, through which the movable plate is connected to the fixed plate 250. When the roller assembly 300 needs to be adjusted, first loosen the first bolt 260 to allow the movable plate to move, then rotate the first adjusting block 230 to push the movable plate, allowing the roller assembly 300 to be adjusted to the required position. Then tighten the first bolt 260 to lock the movable plate and prevent it from loosening during printing. Alternatively, the movable plate can be provided with a movable hole 213, through which the first bolt 260 passes to lock the movable plate to the fixed plate 250. The movable hole 213 can be an elongated hole, with its direction aligned with that of the guide groove 251, allowing for smoother movement and adjustment of the movable plate. Multiple movable holes 213 can also be provided, for example, two, distributed on either side of the first adjusting hole 211, resulting in more balanced force on the movable plate and smoother movement.

[0046] Reference Figure 3 It is understood that, in some embodiments of the present invention, the first adjusting block 230 is a first eccentric shaft, which includes a first threaded rod and a first eccentric head connected to each other. The first eccentric head is connected to the end of the first threaded rod and is eccentrically positioned relative to the axis of the first threaded rod. The other end of the first threaded rod is screwed to the fixed plate 250, and the outer wall of the first eccentric head abuts against the inner wall of the first adjusting hole 211. During adjustment, by rotating the first eccentric head, the first threaded rod rotates relative to the fixed plate 250, and at the same time, the first eccentric head presses and pushes the inner wall of the first adjusting hole 211, thereby causing the movable plate to move, and thus driving the rubber roller assembly 300 to move to the desired position.

[0047] Reference Figure 2Specifically, the first eccentric head is roughly cylindrical, and the first adjusting hole 211 is an oblong hole. The width of the oblong hole matches the outer diameter of the first eccentric head. When the first eccentric head is positioned inside the oblong hole, its outer wall can abut against the inner walls of the two long sides of the oblong hole. In some embodiments, the length direction of the oblong hole can be perpendicular to the direction of the guide groove 251, so that when the first eccentric head rotates, it can better push the inner wall of the long side of the oblong hole, causing the movable plate to move along the direction of the guide groove 251. In this case, a small rotation of the first eccentric head is sufficient to move the movable plate to the desired position, making operation more convenient.

[0048] Reference Figure 3 It is understood that, in order to facilitate user operation of the first adjusting block 230, in some embodiments of the present invention, the first eccentric head is provided with an adjusting groove, which is located at the end of the first eccentric head. Specifically, the adjusting groove can be a cross groove, a straight groove, a plum blossom groove, or a groove of other shapes. The user can insert a corresponding tool into the adjusting groove and then drive the first adjusting block 230 to rotate, thereby adjusting the position of the rubber roller assembly 300, making the operation more convenient and labor-saving.

[0049] Reference Figure 2 It is understood that, in order to further finely adjust the position of the rubber roller assembly 300, in some embodiments of the present invention, the movable plate includes a first movable part 210 and a second movable part 220. A first adjustment hole 211 is disposed in the first movable part 210, and a guide block 212 is disposed in the inner wall of the first movable part 210. The second movable part 220 is movably mounted on the fixed plate 250 in both the horizontal and vertical directions, and the first movable part 210 is movably mounted on the fixed plate 250 in the vertical direction, with the upper end of the first movable part 210 abutting against the lower end of the second movable part 220. Specifically, the upper end of the first movable part 210 is horizontally positioned, and the second movable part 220 is capable of moving horizontally along the upper end of the first movable part 210.

[0050] One end of the rubber roller assembly 300 is rotatably mounted on the fixed plate 250, and the other end is rotatably mounted on the second movable part 220. With this configuration, the user can adjust the verticality of the rubber roller assembly 300 by adjusting the first movable part 210 to move it vertically, or adjust the horizontally by adjusting the second movable part 220. Furthermore, the user can adjust the rubber roller assembly 300 in any direction by coordinating the first and second movable parts 210 and 220. This significantly improves the range and accuracy of the rubber roller assembly 300's position adjustment, allowing the user to move it to a more suitable position and achieve higher alignment accuracy between the rubber roller assembly 300 and the printing media, thereby further improving the printer's print quality.

[0051] Reference Figure 3 It is understood that, in order to facilitate smooth adjustment of the second movable part 220, in some embodiments of the present invention, the second movable part 220 is provided with a second adjustment hole 221, and the printing support assembly also includes a second adjustment block 240. The second adjustment block 240 passes through the second adjustment hole 221 and is connected to the fixed plate 250, and the second adjustment block 240 can push the second movable part 220 to move laterally. Specifically, the second movable part 220 is also locked to the fixed plate 250 by a second bolt 270. When it is necessary to adjust the position of the second movable part 220, the second bolt 270 can be loosened first to allow the second movable part 220 to have a certain amount of room to move relative to the fixed plate 250. Then, the second adjustment block 240 is rotated, and the second adjustment block 240 pushes the second movable part 220 to move laterally. After the second movable part 220 moves into place, the second bolt 270 is tightened to complete the adjustment of the position of the second movable part 220. It should be noted that when actually adjusting the position of the rubber roller assembly 300, the main adjustment is to the vertical position of the rubber roller assembly 300, while the adjustment of the horizontal position of the rubber roller assembly 300 is very small, usually at the micrometer level. In actual adjustment, it is only necessary to slightly turn the first adjusting block 230 and / or the second adjusting block 240 by a very small angle.

[0052] Understandably, in order to enable the second adjusting block 240 to smoothly push the second movable part 220, in some embodiments of the present invention, the second adjusting block 240 is provided with a second screw rod and a second eccentric head. The second screw rod is screwed to the first movable part 210, and the second eccentric head abuts against the inner wall of the second adjusting hole 221. During adjustment, by rotating the second eccentric head, the second screw rod rotates relative to the fixed plate 250, and at the same time, the second eccentric head presses and pushes against the inner wall of the second adjusting hole 221, thereby causing the second movable part 220 to move, and thus driving the rubber roller assembly 300 to move. It should be noted that, in order to enable the second movable part 220 to move laterally via the second adjusting block 240, the second eccentric head is approximately cylindrical, and the second adjusting hole 221 is an oblong hole. The width of the oblong hole matches the outer diameter of the second eccentric head. When the second eccentric head is disposed in the oblong hole, the outer wall of the second eccentric head can abut against the inner walls of the two long sides of the oblong hole. In some embodiments, the length direction of the elongated hole can be set to be perpendicular to the upper end face of the first movable part 210, so that when the second eccentric head rotates, the second eccentric head can better push the inner wall of the long side of the elongated hole, so that the second movable part 220 moves along the upper end of the first movable part 210, that is, the second movable part 220 moves laterally. Moreover, at this time, the second eccentric head can move the second movable part 220 to the required position by rotating a small angle, which makes the operation more convenient.

[0053] Reference Figure 2It is understood that, in some embodiments of the present invention, the end of the second movable part 220 is provided with a mounting groove, and one end of the rubber roller assembly 300 is engaged with the mounting groove, thereby enabling the second movable part 220 to drive the rubber roller assembly 300 to move. Specifically, the rubber roller assembly 300 includes a rubber roller 310 and two bearings 320, which are respectively sleeved on both ends of the rubber roller 310. One bearing 320 is mounted on the second movable part 220, and the other bearing 320 is mounted on the mounting plate 110, thereby enabling the rubber roller 310 to be rotatably mounted.

[0054] Reference Figure 5 Of course, the printer also includes a printhead assembly 400, which is mounted on the mounting plate 110 and positioned opposite to the roller assembly 300. The printhead assembly 400 includes a printhead, a printhead support plate 420, and a printhead mounting bracket. The printhead mounting bracket is fixedly mounted on the mounting plate 110, and the printhead is fixedly mounted on the printhead support plate 420. The printhead support plate 420 can be movably mounted on the printhead bracket 410 in a transverse direction. The printhead support plate 420 is provided with a slot 421 that matches the end of the roller assembly 300. The printhead support plate 420 is engaged with the end of the roller assembly 300 through the slot 421. When the position of the roller assembly 300 is adjusted, the roller assembly 300 can drive the printhead support plate 420 to move, thereby ensuring that the relative position between the printhead and the roller 310 is not affected by the movement of the roller 310, which is beneficial to maintaining the printing quality. Specifically, the print head support 410 may be provided with a transverse hole 411, and the end of the print head support plate 420 is installed in the transverse hole 411 and can move along the transverse hole 411.

[0055] Reference Figure 6 and Figure 7 Specifically, in some embodiments of the present invention, when the printer prints label 500, label 500 is a three-row label with a label paper width of approximately 104mm. The label content is close to the top of the label, requiring dimensions A and B to be basically consistent. If label 500 is manufactured accurately, the rubber roller 310 needs to be perpendicular to the paper feed path; otherwise, the rubber roller 310 needs to be adjusted to adapt to the paper. According to the paper feed direction shown in the figure, if A < B during printing, the second adjusting block 240 needs to be rotated, causing the second movable part 220 to move laterally backward, thereby moving the rubber roller 310 backward to make the values ​​of A and B closer to meet the requirements, thus improving the printing quality.

[0056] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
