Description

Printing device and casing module

Technical Field

The present disclosure relates to printing technology, and in particular, to a printing apparatus and a housing module.

Background

When the bar code label printer performs printing operation, the stamping structure is required to be pressed on the roller mechanism, so that the stamping structure can be ensured to be in contact with the carbon ribbon, and the printing quality is ensured.

The pressing mechanism of the stamping structure of the existing bar code label printer adopts the following steps: the thermal head is movably arranged on an embossing base of the printer, and a plurality of springs are arranged between the embossing base and the thermal head. The thermal head is pressed and pushed against by the stretching force of the springs, so that the thermal head can be in close contact with the roller piece. However, the above structural design is difficult to accurately and actively adjust the degree of the pressing force applied to the roller member by different positions of the thermal head; therefore, when a certain or part of the springs are elastically fatigue or a certain or part of the components of the stamping structure are changed or deviated, the corresponding adjustment processing cannot be performed immediately, so that the stamping structure and the carbon belt are in unreliable and incomplete contact, and the printing quality of the printer is defective.

These terms are used primarily to distinguish one element from another element. In addition, the term "or" as used herein shall include any one or combination of more of the associated listed items as the case may be.

Examples

Referring to fig. 1 to 8, a schematic perspective view, a partially exploded view of one view, a partially exploded view of the other view, a partially cross-sectional side view, a partially cross-sectional front view, a partially cross-sectional side view, a first usage status and a second usage status of a printing device according to an embodiment of the utility model are shown. As shown in the above drawings, the embodiment of the present utility model provides a printing apparatus Z, which includes a casing module D and an embossing module 2. The printing device Z of the present utility model may be a desktop or portable micro-printer, such as a barcode label printer or a thermal printer, but not limited thereto.

First, as shown in fig. 1 to 6, the chassis module D may include a housing assembly D1, a plurality of linkage assemblies D2, and a plurality of elastic assemblies D3. The housing assembly D1 may have a plurality of positioning portions D10. The plurality of linkage assemblies D2 are movably connected to the plurality of positioning portions D10. The elastic components D3 are connected to the linking components D2. For example, the housing assembly D1 may be a chassis of an upper half of the printing device Z. In the present utility model, the mechanism components of the lower half of the printing apparatus Z are omitted, but the printing apparatus Z of the present utility model does not include omitted parts. The shell component D1 may have a plurality of positioning portions D10 formed by protruding outwards on one surface of the embossing module 2, the plurality of positioning portions D10 correspond to the embossing module 2, each positioning portion D10 may have a first connection portion D100, and the first connection portion D100 may be a screw or other type of fastening structure; the positioning portion D10 may be a stud or other type of locking component. The plurality of linking members D2 and the plurality of elastic members D3 are located between the housing module 1 and the embossing module 2. The linkage assemblies D2 may be linkage assemblies, each linkage assembly D2 may have a through hole D20 penetrating through the body, and the inner wall of each linkage assembly D2 corresponding to the through hole D20 may have a second connection portion D21, where the second connection portion D21 may be a screw or other type of engagement structure; therefore, each linking assembly D2 can be connected to the corresponding first connecting portion D100 through the second connecting portion D21 so as to be connected to the corresponding positioning portion D10. One surface of each linkage assembly D2 may further be protruded outwards to form a protrusion D22, and the through hole D20 of each linkage assembly D2 penetrates through the protrusion D22. The elastic component D3 may be a spring or other type of elastic component. One end of each elastic component D3 can be sleeved on the protruding portion D22 of the corresponding linkage component D2, and the other end of each elastic component D3 abuts against the embossing module 2 and is sleeved on one of the protruding portions 20. Wherein the elastic component D3 is configured to apply a first pushing pressure to the imprint module 2 by its own elastic stretching force.

Next, as shown in fig. 1 to 3, 5 and 6, the imprint module 2 is movably disposed in the housing assembly D1. For example, the embossing module 2 may be a structure of a printing device for embossing paper, and may include a printhead and other embossing components. The embossing module 2 has a plurality of protrusions 20 thereon, which correspond to the plurality of positioning portions D10 and are used to provide the elastic component D3 arrangement.

Therefore, when the linking member D2 is rotated in the first direction, the linking member D2 is displaced in a direction approaching the imprint module 2, so as to drive the elastic member D3 to change from the initial state to the compressed state, and the elastic member D3 applies the second pushing pressure to the imprint module 2. The force of the second pushing pressure is larger than that of the first pushing pressure.

Conversely, when the linking member D2 is rotated in the second direction, the linking member D2 is displaced in a direction away from the imprint module 2, so as to drive the elastic member D3 to change from the compressed state to the initial state or the micro-expanded state. When the elastic element D3 is shifted to the micro-expanding state, the elastic element D3 applies a third pushing pressure to the imprint module 2. The force of the third pushing pressure is smaller than that of the second pushing pressure, and the force of the third pushing pressure is larger than or smaller than that of the first pushing pressure.

For example, as shown in fig. 1 to 7, in actual use of the printing device Z of the present utility model, when the interlocking component D2 is located at the initial position (as shown in fig. 6), the space (or the distance) between the interlocking component D2 and the imprinting module 2 is larger, so that the elastic margin of the elastic component D3 is larger; therefore, the elastic component D3 applies a smaller pressure and force (i.e., the first pushing pressure) to the imprint module 2. When the user finds that at least a portion of the information (such as text, numbers, patterns, etc., but not limited to) on the paper (such as heat-sensitive paper, but not limited to) printed by the printing device Z is unclear or lighter, the user can improve the printing definition of the embossing module 2 by adjusting the position of the linkage assembly D2. Furthermore, the user can separate the embossing module 2 from the housing assembly D1, and adjust the linkage assembly D2 corresponding to the position of the embossing module 2 corresponding to the unclear information on the paper; in the process of adjusting the interlocking component D2, at least one interlocking component D2 (i.e. the interlocking component D2 corresponding to the unclear or lighter printed position) is rotated in a first direction (e.g. clockwise or counterclockwise) to drive the interlocking component D2 to move towards the stamping module 2 and away from the housing component D1; at this time, since the space (interval) between the interlocking component D2 and the imprinting module 2 is reduced, the phase change compresses the movable space of the elastic component D3; therefore, the elastic member D3 is pushed and compressed by the linking member D2 to be converted from the initial state to the compressed state (as shown in fig. 7). Then, the elastic component D3 can provide a pressure and force path higher than the first pushing pressure, and apply the second pushing pressure to the imprint module 2, i.e. apply the second pushing pressure to the imprint module 2. The pressing module 2 pressed by the second pressing pressure is higher than the previous pressure, so that the pressing module 2 can strengthen the force of contacting the paper or the roller assembly (not shown in the figure), and deepen the definition of the information on the paper pressed by the printing device Z, thereby improving the printing quality.

Conversely, as shown in fig. 1 to 8, when the user finds that at least a part of the information (such as text, numbers, patterns, etc., but not limited to,) on the paper printed by the printing device Z is too dark, or the information is burnt out, the user can separate the imprinting module 2 from the housing assembly D1 first, and adjust the linkage assembly D2 corresponding to the position of the imprinting module 2 corresponding to the position where the information is not displayed well on the paper; in the process of adjusting the interlocking component D2, at least one interlocking component D2 (i.e. the interlocking component D2 corresponding to the position with poor quality printed on the surface) is rotated in a second direction (e.g. clockwise or anticlockwise direction, but opposite to the first direction) so as to drive the interlocking component D2 to move towards the housing component D1 and away from the embossing module 2; at this time, since the space (interval) between the interlocking component D2 and the imprinting module 2 is increased (as shown in fig. 7 or fig. 8 and fig. 6 in comparison), the interlocking component D2 releases a part of space for compressing the elastic component D3, and the phase change increases the moving space and moving margin of the elastic component D3; therefore, the elastic component D3 obtains more expansion space and changes from the compressed state to the slightly expanded state or the initial state (the change to the slightly expanded state or the initial state depends on the degree to which the user releases the elastic component D3). When the elastic component D3 is shifted to the micro-expanding state (as shown in fig. 8), the space compressed by the elastic component D3 is enlarged, so that the pressure and force applied by the elastic component D3 to the imprint module 2 are smaller than the second pushing pressure and larger than the first pushing pressure; thus, the print quality of the printing apparatus Z can be gradually corrected.

Therefore, according to the above technical scheme, the printing device Z of the present utility model utilizes the plurality of positioning portions D10 and the plurality of interlocking members D2 provided between the housing assembly D1 and the imprinting module 2, and each positioning portion D10 and the corresponding interlocking member D2 correspond to different positions of the imprinting module 2, so that the printing position (i.e. the printing position) of the imprinting module 2 with poor printing quality can be adjusted, each position of the imprinting module 2 contacting the carbon ribbon can contact the carbon ribbon evenly and reliably, and the imprinting module 2 prints information with consistent quality, thereby improving the printing quality.

In addition, according to the above disclosure, the present disclosure further provides a casing module D suitable for a printing apparatus, and the casing module may include a casing assembly D1 and a plurality of linkage assemblies D2. The housing assembly D1 may have a plurality of positioning portions D10, the housing assembly D1 being configured to connect with the platen module 2 of the printing device Z. The plurality of linkage assemblies D2 are movably connected to the plurality of positioning portions D10, and each linkage assembly D2 is configured as an elastic assembly D3 for connecting to the printing device Z.

Further, each positioning portion D10 may have a first connecting portion D100, each coupling element D2 may have a through hole D20 penetrating through the body, an inner wall of each coupling element D2 corresponding to the through hole D20 may have a second connecting portion D21, and each coupling element D2 may be connected to the corresponding first connecting portion D100 through the second connecting portion D21 so as to be connected to the corresponding positioning portion D10. The specific embodiments may be similar to those described in the foregoing embodiments, and will not be described herein in detail.

Further, one surface of each of the linking members D2 may be protruded outwards to form a protrusion D22, and the through hole D20 penetrates the protrusion D22. One end of the elastic component D3 is sleeved on the protruding portion D22. The specific embodiments may be similar to those described in the foregoing embodiments, and will not be described herein in detail.

Further, when the linking member D2 is rotated in the first direction, the linking member D2 is displaced in a direction approaching the imprint module 2, so as to drive the elastic member D3 to change from the initial state to the compressed state. The specific embodiments may be similar to those described in the foregoing embodiments, and will not be described herein in detail.

Further, when the linking member D2 is rotated in the second direction, the linking member D2 is displaced away from the imprint module 2, so as to drive the elastic member D3 to change from the compressed state to the initial state or the micro-expanded state. The specific embodiments may be similar to those described in the foregoing embodiments, and will not be described herein in detail.

However, the above examples are only one of possible embodiments and are not intended to limit the present utility model.
