DETAILED DESCRIPTION

[0035] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the figures and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0036] Please refer to Figure 1 and Figure 2 A printer 100 provided by an embodiment of the present application includes a body 10, a cover 20 and a detection assembly 30. The body 10 has a paper feeding opening 11. The cover 20 includes a connecting end 201 and a movable end 202. The connecting end 201 and the movable end 202 are two ends of the cover 20 arranged oppositely. The connecting end 201 is rotationally connected with the body 10, so that the cover 20 has a closed state and an open state. The body 10 has a mounting surface 12 on the part where the paper feeding opening 11 is formed and / or the movable end 202. The mounting surface 12 is provided with a mounting hole structure 121. The detection assembly 30 is located in the mounting hole structure 121 and is lower than the mounting surface 12.

[0037] It can be understood that the top surface of the body 10 has a paper feeding opening 11, and the printed label paper can be extended out from the body 10 to the outside through the paper feeding opening 11. The cover 20 is in the shape of a plate structure with a certain curvature, and the connecting end 201 of the cover 20 can be rotatably connected with the body 10, so that the cover 20 can be rotated towards the body 10 and away from the body 10, so that the cover 20 can be switched between the closed state and the open state. More clearly, when the cover 20 is rotated towards the body 10 to be closed with the body 10, the cover 20 is in the closed state, and the movable end 202 of the cover 20 is arranged opposite to the paper feeding opening 11. When the cover 20 is rotated away from the body 10 to be arranged at an angle with the body 10, the cover 20 is in the open state, and the movable end 202 of the cover 20 is away from the paper feeding opening 11.

[0038] It should be noted that the side wall of the body 10 forming the paper feeding opening 11 can have a mounting surface 12, or the movable end 202 of the cover 20 can have a mounting surface 12, or both the side wall of the body 10 forming the paper feeding opening 11 and the movable end 202 of the cover 20 have a mounting surface 12, and the mounting surface 12 is provided with a mounting hole structure 121, and the detection assembly 30 can be arranged in the mounting hole structure 121, so that the detection assembly 30 is entirely recessed in the interior of the printer 100, that is, the detection assembly 30 does not extend out of the mounting surface 12, and the entire detection assembly 30 is located in the interior of the mounting hole structure 121.

[0039] When printing the label paper, the cover 20 is rotated to the closed state, and the detection assembly 30 can be opposite to the paper feeding opening 11, and the printed label paper can be extended out from the body 10 to the outside through the paper feeding opening 11. At this time, the detection assembly 30 can detect the label paper to ensure that the printing process of the label paper is efficient, accurate and reliable, and since the detection assembly 30 is recessed in the interior of the printer 100, it can prevent the label paper from rubbing against the detection assembly 30 and adversely affecting the detection accuracy of the detection assembly 30.

[0040] Please refer to Figure 2 In some embodiments, the mounting surface 12 is provided with a rib 122, and the rib 122 is arranged adjacent to the mounting hole structure 121.

[0041] It can be understood that the ribs 122 protrude outward relative to the mounting surface 12, so that the top surface of the ribs 122 is higher than the mounting surface 12, so that the top surface of the ribs 122 is above the mounting hole structure 121, and in the process of printing the label paper, the printed label paper extends out of the paper outlet 11, and the label paper contacts the ribs 122, so that the label paper passes above the mounting hole structure 121, that is, the label paper passes above the detection assembly 30, so that the label paper is separated from the detection assembly 30, and further friction between the label paper and the detection assembly 30 can be prevented.

[0042] In the embodiment, the mounting surface 12 is provided with a plurality of ribs 122, and the plurality of ribs 122 are sequentially and spaced apart along the width direction of the machine body, so that the label paper extending out of the paper outlet 11 can contact the plurality of ribs 122, that is, the plurality of ribs 122 support the label paper, and further friction between the label paper and the detection assembly 30 can be prevented.

[0043] Please refer to Figure 2 In some embodiments, the detection assembly 30 includes a first sensor group 31, the first sensor group 31 includes a first transmitting sensor 311, a first receiving sensor 312, and a light guide 313, the first transmitting sensor 311 and the first receiving sensor 312 are arranged on one of the machine body 10 and the cover 20, the light guide 313 is arranged on the other one of the machine body 10 and the cover 20, and the light guide 313 includes a receiving end 3131 and a transmitting end 3132 connected to each other, when the cover 20 is in the closed state, the receiving end 3131 is opposite to the first transmitting sensor 311 in position, and the transmitting end 3132 is opposite to the first receiving sensor 312 in position.

[0044] In the embodiment, the first transmitting sensor 311 and the first receiving sensor 312 are arranged on the cover 20, and the end surface of the movable end 202 of the cover 20 has the mounting surface 12, when the cover 20 is in the closed state, the end surface of the movable end 202 faces the paper outlet plate on the machine body 10, the first transmitting sensor 311 and the first receiving sensor 312 are recessed on the mounting surface 12, so that the first transmitting sensor 311 and the first receiving sensor 312 are located inside the movable end 202, that is, the first transmitting sensor 311 and the first receiving sensor 312 do not protrude from the end surface of the movable end 202, and the first transmitting sensor 311 and the first receiving sensor 312 are spaced apart along the width direction of the machine body 10.

[0045] The light guide 313 is arranged on the machine body 10, and the entire light guide 313 is located inside the machine body 10. The mounting surface 12 on the machine body 10 has a mounting hole structure 121. The receiving end 3131 and the emitting end 3132 of the light guide 313 are inserted into the mounting hole structure 121 on the machine body 10. When the cover body 20 is in the closed state, the receiving end 3131 can be opposite to the position of the first emitting sensor 311, and the emitting end 3132 can be opposite to the position of the first receiving sensor 312. The first emitting sensor 311 can send a light beam towards the receiving end 3131. After the receiving end 3131 receives the light beam, the light beam can be transmitted to the emitting end 3132, so that the light beam can be sent from the emitting end 3132 towards the first receiving sensor 312. Thus, the paper feeding condition of the paper feeding opening 11 can be detected by the condition of receiving the light beam by the first receiving sensor 312.

[0046] Of course, it should be noted that in other embodiments, the first emitting sensor 311 and the first receiving sensor 312 can also be arranged on the machine body 10, and the light guide 313 can be arranged on the movable end 202 of the cover body 20. The position of the first sensor group 31 can be set according to actual conditions.

[0047] Please refer to Figure 2 In some embodiments, the mounting hole structure 121 includes two first mounting holes 1211 and two second mounting holes 1212.

The light guide 313 is arranged inside the machine body 10, and the receiving end 3131 and the emitting end 3132 can be respectively inserted into the two first mounting holes 1211 from the inside of the machine body 10. It should be noted that the receiving end 3131 and the emitting end 3132 do not protrude out of the first mounting hole 1211.

[0057] Please refer to Figure 4 In some embodiments, the connecting column 3130 comprises a first connecting column 3133, an arc-shaped connecting column 3134 and a second connecting column 3135 connected in sequence, the first connecting column 3133 has the receiving end 3131, the second connecting column 3135 has the emitting end 3132, and the limiting column 3136 is connected with the arc-shaped connecting column 3134.

[0058] In the embodiment, the first connecting column 3133 is connected with one end of the arc-shaped connecting column 3134, and the second connecting column 3135 is connected with the other end of the arc-shaped connecting column 3134, so that the shape of the connecting column 3130 is similar to a U-shaped structure, the arc-shaped connecting column 3134 constitutes a closed end of the connecting column 3130, the first connecting column 3133 and the second connecting column 3135 constitute an open end 141 of the connecting column 3130, the limiting column 3136 is connected with the arc-shaped connecting column 3134, the receiving end 3131 and the transmitting end 3132 are respectively inserted into the two first mounting holes 1211, the open end of the connecting column 3130 can be limited, the limiting column 3136 is inserted into the limiting hole 14 in a plug-in manner, the closed end of the connecting column 3130 can be limited, so that the connecting column 3130 can be more stably installed on the fuselage 10.

[0059] Please refer to Figure 3 and Figure 5 In some embodiments, the side wall of the limiting hole 14 has an opening 141, the opening 141 is in communication with the limiting hole 14, and the limiting column 3136 is inserted into the limiting hole 14 from the opening 141.

[0060] Specifically, the side wall of the limiting hole 14 away from the first mounting hole 1211 has an opening 141, the opening 141 can be used for inserting the limiting column 3136 into the limiting hole 14 in a direction perpendicular to the axis of the limiting hole 14, more specifically, the axis of the first mounting hole 1211 is perpendicular to the axis of the limiting hole 14, when the connecting column 3130 is inserted into the first mounting hole 1211 along the axis of the first mounting hole 1211, the limiting column 3136 gradually approaches the limiting hole 14 in a direction perpendicular to the axis of the limiting hole 14, so that the limiting column 3136 can be inserted into the limiting hole 14 from the opening 141, and the light guide 313 can be conveniently installed on the fuselage 10.

[0061] Please refer to Figure 5 In some embodiments, the opening 141 has two oppositely arranged guide inclined surfaces 142, and the distance between the two guide inclined surfaces 142 gradually decreases in a direction close to the axis of the limiting hole 14.

[0062] It can be understood that the opening 141 penetrates the side wall of the limiting hole 14, and the opening 141 can extend along the axial direction of the limiting hole 14, and the opening 141 can have two oppositely arranged guide inclined surfaces 142, the two guide inclined surfaces 142 can be symmetrically arranged, and the distance between the two guide inclined surfaces 142 gradually decreases in the direction close to the axial line of the limiting hole 14, so that the guide inclined surface 142 can be inclined towards the direction close to the axial line of the limiting hole 14, and the opening 141 has one side with a larger size and the other side with a smaller size, and during the process of inserting the limiting column 3136 into the limiting hole 14 from the opening 141, the limiting column 3136 can be inserted into the opening 141 from the side with a larger size, and the limiting column 3136 can be moved along the guide inclined surface 142 to the smaller side of the opening 141, until the limiting column 3136 is completely inserted into the limiting hole 14, and the two guide inclined surfaces 142 can guide the limiting column 3136 to be inserted into the limiting hole 14, so as to facilitate the installation of the light guide 313.

[0063] Please refer to Figure 5 In some embodiments, the guide inclined surface 142 is provided with a limiting protrusion 143.

[0064] It can be understood that after the limiting column 3136 is inserted into the limiting hole 14 from the opening 141, the limiting column 3136 has the risk of being separated from the limiting hole 14 from the opening 141, and the limiting protrusion 143 arranged on the guide inclined surface 142 can prevent the limiting column 3136 from being separated from the limiting hole 14 from the opening 141, so that the limiting column 3136 can be stably inserted into the limiting hole 14.

[0065] Please refer to Figure 2 In some embodiments, the distance between the first transmitting sensor 311 and the first receiving sensor 312 is h, and h satisfies: 10mm≥h≥5mm.
