Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a label printer with a cover closing detection function. Background Art

[0002] The working principle of thermal printing is that a row of semiconductor heating elements are installed on the thermal head. These heating elements will quickly generate high temperatures when a certain current passes through them. After the thermal head is heated and contacts the thermal paper, the required content can be printed on the thermal paper. Therefore, maintaining maximum line contact between the thermal head and the thermal paper is the key to improving print quality.

[0003] The top cover of the label printer is often opened, for example, to replace label paper or complete internal maintenance of the machine. When the top cover is closed, if the top cover is not completely closed or there is a closing deviation between the two, it will cause printing errors of the label paper and cause consumables loss. In addition, when there is a problem with the closure of the top cover, the heating components of the machine body are exposed, which can easily burn the user's hands. Utility Model Content

[0039] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] In order to solve the technical problem that label printers in the prior art are difficult to detect when the upper cover is closed, the present invention provides a label printer with a cover closure detection function, which can detect the status of the printer's box cover during the printer's box cover opening process.

[0041] In order to achieve the above technical purpose, the present invention adopts the following technical solutions:

[0042] like Figure 1-3 As shown, the utility model provides a label printer with a cover-closed detection function, including a printer body 10, an upper cover 20, a cover-closed detection member 30 and a trigger member 40. The printer body 10 is provided with an open paper bin 11, which is used to accommodate label paper; the upper cover 20 is hinged to the printer body 10 and can be opened or closed by rotating the paper bin 11; the cover-closed detection member 30 is installed on the printer body 10; the trigger member 40 is provided on a side of the upper cover 20 close to the cover-closed detection member 30. When the upper cover 20 is closed, the trigger member 40 contacts the cover-closed detection member 30 to detect the closed state of the upper cover 20.

[0043] Specifically, the label printer is provided with a printer body 10 and an upper cover 20. The printer body 10 is provided with an open paper bin 11. Label paper can be placed in the paper bin 11. The upper cover 20 is hinged to the printer body 10. After the label paper is placed in the paper bin 11, the upper cover 20 closes the paper bin 11, and the label paper can be printed through the printer body 10. Since the label printer is also provided with a covering detection member 30 and a trigger member 40, the covering detection member 30 and the trigger member 40 are respectively provided on the printer body 10 and the upper cover 20. When the upper cover 20 is closed, the trigger member 40 contacts the detection member. The detection member can detect the covering state of the upper cover 20 by sensing the contact of the trigger member 40, thereby ensuring that the upper cover 20 is stably covered on the printer body 10, providing protection for the stable operation of the printer, and ensuring the safety of the user.

[0044] In this embodiment, the rubber roller of the label printer is arranged on one of the upper cover 20 or the printer body 10, and the print head of the label printer is arranged on the printer body 10. When the upper cover 20 is closed, a paper feed channel is formed between the upper cover 20 and the printer body 10. The rubber roller and the print head are arranged in the paper feed channel. The rubber roller leads the label paper out of the paper bin 11 and feeds the paper through the paper feed channel. When the label paper passes the print head, it is printed by the print head.

[0045] In this embodiment, the printer is provided with an indicator light. When the cover detection member 30 detects the contact of the trigger member 40, the indicator light of the printer lights up, indicating that the upper cover 20 is tightly covered on the printer body 10. When the upper cover 20 is opened, the trigger member 40 moves away from the cover detection member 30, and the indicator light of the printer goes out.

[0046] It can be understood that the covering detection part 30 can be provided with a pressure sensing module. When the upper cover 20 is closed, the trigger part 40 acts on the covering detection part 30 through the pressure, so that the covering detection part 30 detects whether the trigger part 40 is in contact. Or, a trigger switch can be provided. When the upper cover 20 is closed, the trigger part 40 contacts the trigger switch, and the covering detection part 30 senses the contact of the trigger part 40.

[0047] In one embodiment, Figure 2-3 As shown in Figure 5 , the cover detection member 30 includes a mating member 31. When the upper cover 20 is closed, the trigger member 40 pushes the mating member 31 to a predetermined position, allowing the cover detection member 30 to detect the closed state of the upper cover 20. Specifically, due to the arrangement of the mating member 31 on the cover detection member 30, when the upper cover 20 is closed, the trigger member 40 pushes the mating member 31 a certain distance. When it reaches the predetermined position on the cover detection member 30, the cover 20 is detected.

[0048] It is understandable that the matching member 31 can be connected to the covering detection member 30 in a sliding connection or a rotational connection, etc., which can be displaced relative to the preset position, and it only needs to be able to move to the preset position under the push of the trigger member 40.

[0049] In this embodiment, the cover detection member 30 is also provided with a reset spring (not marked in the figure), which abuts against the matching member 31. When the trigger member 40 is out of contact with the matching member 31, the matching member 31 is reset under the drive of the reset spring.

[0050] It can be understood that the preset position of the cover detection part 30 is provided with a sensing element such as a pressure sensor or a proximity switch. When the matching part 31 moves to the pressure sensor under the push of the trigger part 40, the pressure sensor senses the pressure change, thereby triggering the indicator light of the printer to light up, and it can be detected that the printer cover 20 is in the closed state at this time; or when the proximity switch senses that the matching part 31 is approaching, it triggers the indicator light of the printer to light up, and it can be detected that the printer cover 20 is in the closed state at this time. The matching part 31 can also be provided with a displacement sensor. When the displacement sensor senses that the matching part 31 moves to the preset position, it triggers the indicator light of the printer to light up, and it can be detected that the printer cover 20 is in the closed state at this time.

[0051] In one embodiment, the cover detection member 30 is further provided with a sensing portion, which is located on the moving path of the matching member 31. The sensing portion detects the cover state of the upper cover 20 by sensing the matching member 31. Specifically,

[0052] In this embodiment, the sensing portion is provided with a sensing element such as a pressure sensor or a proximity switch. When the sensing element senses the fitting member 31 , it is detected that the upper cover 20 is in the closed state.

[0053] In one embodiment, the engaging member 31 is rotatably connected to the cover detection member 30. When the upper cover 20 is closed, the trigger member 40 pushes the engaging member 31 to rotate. Specifically, when the upper cover 20 is closed, the trigger member 40 pushes the engaging member 31 to rotate to a predetermined position of the cover detection member 30, thereby determining that the upper cover 20 is fully closed, thereby detecting the closing condition of the upper cover 20.

[0054] In this embodiment, the sensing part is located on the rotation path of the fitting 31 and is provided with a contact switch. When the fitting 31 contacts the contact switch by rotation, the contact switch closes and the trigger indicator light turns on, thereby realizing the detection of the closing status of the upper cover 20.

[0055] In one embodiment, Figure 2-3 As shown in Figures 5 and 6 , the cover detection member 30 is further provided with a terminal head 32, which is located at the end of the cover detection member 30 away from the mating member 31. Specifically, the cover detection member 30 can be connected to the power module via the terminal head 32, and the power module is used to supply power to maintain the operation of the cover detection member 30. By arranging the terminal head 32 at the end of the cover detection member 30 away from the mating member 31, the wire connecting the terminal head 32 can be prevented from obstructing the contact between the trigger member 40 and the cover detection member 30.

[0056] In one embodiment, Figure 2-5As shown, the printer body 10 is provided with a limit installation slot 12, and the capping detection member 30 is installed in the limit installation slot 12. Specifically, the limit installation slot 12 limits the capping detection member 30, thereby ensuring the stability of the capping detection member 30.

[0057] In one embodiment, Figure 2-5 As shown, the printer body 10 is provided with a first limiting wall 13 and a second limiting wall 14, which are arranged opposite each other and form a limiting installation slot 12. Specifically, the first limiting wall 13 and the second limiting wall 14 can limit the position of the cover detection member 30 on both sides. The limiting installation slot 12 formed by the first limiting arm and the second limiting arm does not require a separate limiting installation slot 12 structure in the printer body 10. An opening can be formed on the side of the limiting installation slot 12 to facilitate wiring of the cover detection member 30.

[0058] In one embodiment, Figure 2-5 As shown, the printer body 10 is further provided with a positioning rod 15, and the capping detection member 30 is provided with a positioning hole 33 adapted to fit the positioning rod 15. The positioning rod 15 penetrates the positioning hole 33. Specifically, the positioning rod 15 provides a positioning for the installation of the capping detection member 30. The cooperation between the positioning rod 15 and the positioning hole 33 in the capping detection member 30 prevents the capping detection member 30 from shifting, thereby ensuring the stability of the capping detection member 30.

[0059] In one embodiment, Figure 2-5 As shown, the printer body 10 is further provided with a positioning groove 16, and the capping detection member 30 is provided with a positioning protrusion 34 adapted to the positioning groove 16. The positioning protrusion 34 is inserted into the positioning groove 16. Specifically, the positioning protrusion 34 on the capping detection member 30 cooperates with the positioning groove 16 on the printer body 10 to further position the capping detection member 30 and ensure its stability.

[0060] In this embodiment, Figure 2-5 As shown, the positioning hole 33 and the positioning protrusion 34 are respectively located at two ends of the covering detection member 30.

[0061] It is understandable that the trigger member 40 can be any structure that can contact the closing detection member 30 when the upper cover 20 is closed.

[0062] In one embodiment, Figure 2-4 As shown, when the upper cover 20 is closed, the trigger member 40 is engaged with the printer body 10. Specifically, the trigger member 40 is in contact with the closing detection member 30 and can also be engaged with the printer body 10, thereby locking the upper cover 20.

[0063] In this embodiment, the printer utilizes the original locking component on the upper cover 20 to trigger the cover detection component 30, and no separate trigger component is required, thereby simplifying the printer structure.

[0064] It is understandable that the trigger member 40 can be engaged with the printer body 10 by friction with the printer body 10 , or by providing a protruding structure that cooperates with the printer body 10 .

[0065] In one embodiment, Figure 1-4 As shown, the trigger member 40 is provided with a hook portion 41. The hook portion 41 extends toward the cover detection member 30. When the upper cover 20 is closed, the hook portion 41 contacts the cover detection member 30 and engages with the printer body 10. Specifically, the provision of the hook portion 41 enables the trigger member 40 to form a hook structure. When the upper cover 20 is closed, the hook structure of the hook portion 41 can engage the trigger member 40 with the printer body 10, thereby locking the upper cover 20.

[0066] In this embodiment, when the upper cover 20 is closed, the lower end of the hook portion 41 pushes the mating piece 31 and drives the mating piece 31 to rotate. When the upper cover 20 is completely closed, the hook portion 41 drives the mating piece 31 to rotate to the sensing portion of the closing sensing piece, thereby detecting the closing state of the upper cover 20.

[0067] In one embodiment, Figure 1 As shown, the printer body 10 is provided with a penetration hole 17. When the upper cover 20 is closed, the hook portion 41 overcomes the elastic force and penetrates the penetration hole 17, thereby engaging with the printer body 10 under the elastic force. In this embodiment, the penetration hole 17 provides a position limit for the trigger member 40, preventing the trigger member 40 from deflecting, thereby ensuring stable locking of the upper cover 20.

[0068] It is understandable that the trigger member 40 can be fixed to the upper cover 20 and engaged with the printer body 10 through its own elastic force, or be rotatably connected to the upper cover 20 and engaged with the printer body 10 through the elastic force of an external elastic component.

[0069] In one embodiment, the trigger member 40 is rotatably connected to the upper cover 20 , and the label printer further includes a locking spring 50 , one end of the locking spring 50 abuts against the trigger member 40 , and the other end of the locking spring 50 abuts against the upper cover 20 .

[0070] In one embodiment, Figure 2-4 As shown, the upper cover 20 is provided with an abutting wall 21 , the abutting wall 21 is opposite to the trigger member 40 , and the locking spring 50 is located between the abutting wall 21 and the trigger member 40 .

[0071] In this embodiment, the abutment arm is provided with a limit post 211, and the locking spring 50 is mounted on the limit post 211. This ensures the stability of the locking spring 50. To open the top cover 20, one only needs to overcome the elastic force of the locking spring 50, rotate the trigger member 40, disengage the trigger member 40 from the printer body 10, and then rotate the top cover 20 upward.

[0072] In one embodiment, Figure 2-5 As shown, the printer body 10 is further provided with a limit member 18, which is opposite to the cover detection member 30. The limit member 18 is provided with a limit cavity 181 with a side opening. When the upper cover 20 is closed, the side of the hook portion 41 away from the cover detection member 30 is located in the limit cavity 181, and the side of the hook portion 41 close to the cover detection member 30 contacts the cover detection member 30. Specifically, the hook portion 41 passes through the perforation 17 and then enters the limit cavity 181. The limit cavity 181 can provide a limit for the hook portion 41, thereby ensuring stable contact between the hook portion 41 and the cover limit member 18.

[0073] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the present invention is described in detail: when printing label paper, the label paper is placed in the paper bin 11, and then the upper cover 20 is closed. During the closing process of the upper cover 20, the trigger part 40 overcomes the elastic force of the locking spring 50, so that the hook part 41 is penetrated into the perforation 17. During the penetration of the perforation 17, the hook part 41 pushes the matching part 31 and drives the matching part 31 to rotate. When the hook part 41 penetrates the perforation 17, the locking spring 50 acts on the elastic force of the trigger part 40, so that the hook part 41 is engaged with the printer body 10. At the same time, the hook part 41 drives the matching part 31 to rotate to the sensing part of the closing sensing part, and the trigger indicator light is on. At this time, the upper cover 20 is in a closed state, thereby detecting the closing state of the upper cover 20. When the upper cover 20 needs to be opened, it is only necessary to overcome the elastic force of the locking spring 50 to control the rotation of the trigger member 40 so that the trigger member 40 is disengaged from the printer body 10 and the contact with the cover detection member 30, and then the upper cover 20 is rotated upward.

[0074] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
