[0002] In people's daily life, work, study, there are many requirements for label printing, sticky note printing or wrong question printing. The label printer uses the thermal printing principle. The printer converts the received data into dot matrix signals to control the heating of the thermal unit, and heats and develops the thermal coating on the thermal paper. The label printer using the thermal printing principle has the advantages of fast speed, low noise, clear printing and convenient use, so it is widely used.

[0003] The existing label printer is internally loaded with a roll of thermal printing paper, and the label printer will continuously feed the paper according to the printing content. In addition, the label printer is generally equipped with a cutting knife, which is used to cut the printing paper through the cutting knife after a label is printed, and the printed label is separated from the printing paper. The existing cutting knife is arranged inside the printer housing and can reciprocate up and down above the paper feeding channel of the printing paper. The printing paper is cut by pressing the cutting knife. The advantage of this method is that the cut of the printing paper is flat and convenient for users to operate. However, in order to replace the printing paper, the label printer is generally set in two parts: the printer main body and the printer cover. The cutting knife is generally arranged on the printer cover. When the printer cover is closed, the cutting knife is located inside the printer and will not leak out. When the printer cover is opened, the cutting knife retracts inside the printer cover when not pressed, but once the cutting knife is accidentally pressed, it will protrude and may scratch the operator, there is a certain safety hazard.

[0035] See Figures 1-4 As shown, a label printer 100 with a cutter protection in this embodiment includes:

[0036] A printer main body 102;

[0037] A printer cover 101, which is installed on the printer main body 102 in an openable and closable manner. When the printer cover 101 and the printer main body 102 are in a closed state, a paper feeding channel 400 for the printing paper is formed therebetween;

[0038] A cutter assembly, which is arranged on the printer cover 101 in a reciprocating manner to perform a paper cutting operation on the printing paper 500 in the paper feeding channel 400 of the printing paper;

[0039] And a cutter protection assembly, which is arranged on the printer cover 101 and is linked with the open and closed states of the printer cover 101: the cutter protection assembly is located at a first position separated from the cutter assembly when the printer cover 101 is closed, and the cutter assembly reciprocates freely to perform a paper cutting operation; the cutter protection assembly is located at a second position for locking the cutter assembly when the printer cover 101 is opened.

[0040] For the label printer in this embodiment, by setting the cutter protection assembly and linking it with the open and closed states of the printer cover 101, when the printer cover 101 is closed, the cutter protection assembly will not interfere with the normal paper cutting operation of the cutter assembly, and the cutter assembly can reciprocate freely. When the printer cover 101 is opened, the cutter assembly will be locked, and the cutter assembly cannot be pressed after being locked. The paper cutting knife of the cutter assembly will not extend out in the state where the printer cover 101 is opened, avoiding scratching personnel when the cutter assembly extends out when the printer cover 101 is opened.

[0041] Therefore, the label printer in this embodiment realizes the self-protection function of the paper cutting knife, and automatically links to achieve locking and unlocking according to the state of the printer cover 101, without the need for the user to perform relevant operations, which is safe and reliable.

[0042] As an alternative implementation of this embodiment, refer to Figure 2 , Figure 3 and Figure 4 As shown, the cutter assembly in this embodiment includes a cutter 204 and a cutter pressing member 201 that are reciprocally arranged on the printer cover 101. By pressing the cutter pressing member 201, the cutter 204 is triggered to move into the paper feeding channel 400 of the printing paper for cutting the printing paper; the cutter protection assembly includes a protection linkage member 301 arranged on the printer cover 101. The protection linkage member 301 is located at a first position separated from the cutter pressing member 201 when the printer cover 101 is closed. By pressing the cutter pressing member 201, the cutter 204 is triggered to reciprocate freely. The protection linkage member 301 is located at a second position abutting against the cutter pressing member 201 when the printer cover 101 is opened, and the cutter pressing member 201 and the cutter 204 are locked by the protection linkage member 301.

[0043] The cutter protection assembly of this embodiment is linked with the printer cover 101 through the protection linkage member 301. When the printer cover 101 is opened, the protection linkage member 301 is synchronously triggered to act and abut against the cutter pressing member 201. At this time, the cutter pressing member 201 cannot be pressed, and the cutter 204 is kept retracted inside the printer cover 101 to avoid injury caused by the cutter 204 protruding.

[0044] The way to implement the protection linkage member 301 in this embodiment can adopt a mechanical linkage method, and the specific implementation method is as follows:

[0045] A label printer with cutter protection in this embodiment includes a protection trigger member 304 arranged on the printer main body 102. The protection trigger member 304 is in contact with the protection linkage member 301 in the closed state of the printer cover 101, so that the protection linkage member 301 is located at the first position. The protection trigger member 304 is separated from the protection linkage member 301 in the opened state of the printer cover 101, and the protection linkage member 301 is reset to the second position.

[0046] In this embodiment, the protection trigger member 304 triggers the protection linkage member 301 to act when the printer cover 101 is opened and closed, realizing the synchronous linkage between the protection linkage member 301 and the printer cover 101.

[0047] In order to achieve the resetting of the protection linkage 301, the protection linkage 301 described in this embodiment is rotatably mounted on the printer cover 101 through a rotating shaft 302, and the cutter protection assembly includes an elastic member 303 arranged between the protection linkage 301 and the printer cover 101. When the printer cover 101 is in a closed state, the elastic member 303 is in a deformed state. When the printer cover 101 is in an open state, the elastic member 303 restores the deformation and acts on the protection linkage 301 to maintain the second position.

[0048] As an optional implementation of this embodiment, the protection linkage member 301 described in this embodiment is a lever with a certain extended length, the rotating shaft 302 is fixed on the inner wall of the printer cover 101, and the middle part of the lever can be horizontally rotatably installed on the rotating shaft 302 to form a lever structure; one end of the lever located on the rotating shaft 302 is the driving end, and the other end located on the rotating shaft 302 is the locking end; the protection trigger member 304 is pressed against the driving end of the lever when the printer cover 101 is closed, pressing the lever to rotate and drive the locking end away from the cutter pressing member 201. The elastic member 303 is a compression spring arranged between the locking end of the lever and the printer cover 101. The compression spring is in a compressed state after installation. When the printer cover 101 is closed, the protection trigger member 304 pushes the locking end of the lever to move toward the compression spring side, further compressing the compression spring. After the printer cover 101 is opened, the protection trigger member 304 is separated from the driving end of the lever and is no longer subjected to force. The compression spring recovers its deformation to reset the lever.

[0049] In order to enable the protection trigger member 304 to trigger the action of the protection linkage member 301, a through hole is provided on the inner wall of the printer cover 101 described in this embodiment at a position corresponding to the driving end of the lever. The protection trigger member 304 is a support rod arranged on the printer body, and a laterally protruding pressure block is provided at the upper end of the support rod. The upper end of the support rod passes through the through hole when the printer cover is closed, and the protruding pressure block at the upper end of the support rod presses against the driving end of the lever.

[0050] Furthermore, a label printer with cutter protection according to this embodiment, one end of the printer cover 101 is rotatably connected to the printer main body 102 to realize the opening and closing of the printer cover 101 relative to the printer main body 102; an outlet 700 communicating with the paper feed channel 400 of the printing paper is formed between the other end of the printer cover 101 and the printer main body 102. The printer cover 101 includes a printer cover shell with an open mounting chamber inside and a printer cover plate mounted on the open end of the printer cover shell. The cutter assembly is arranged at one end close to the outlet 700 in the mounting chamber of the printer cover shell, the cutter protection assembly is arranged in the mounting chamber of the printer cover shell between the cutter assembly and the outlet 700, and the elastic member 303 is arranged in the mounting chamber of the printer cover shell, with one end abutting against the protection linkage member 301 and the other end abutting against the printer cover shell.

[0051] Specifically, in a label printer with cutter protection according to this embodiment, a first threaded post 104 and a second threaded post 105 are arranged at the end near the outlet 700 in the mounting chamber of the printer cover shell. The printer cover plate is fixedly connected to the threaded posts of the printer cover shell by screws. A connecting plate 106 is arranged between the first threaded post 104 and the second threaded post 105, and one end of the elastic member 303 is fixedly abutted against the connecting plate 106.

[0052] Since the protection linkage member 301 of this embodiment realizes elastic reset through a compression spring, in order to make the protection linkage member 301 abut against the cutter pressing member 201 at a determined position under the elastic force of the compression spring, see Figure 2 As shown, the cutter protection assembly of this embodiment includes a protection limiting member 107 arranged on the printer cover 101. The protection limiting member 107 is located between the protection linkage member and the cutter assembly and is used for limiting and abutting against the protection linkage member 301 when the printer cover 101 is opened, so as to keep the protection linkage member 301 in the second position.

[0053] In order to realize the abutment between the cutter pressing member 201 and the protection linkage member 301, see Figure 3 As shown, a locking block 202 is arranged on the cutter pressing member 201 of this embodiment. The locking block 202 abuts against the protection linkage member 301 when the printer cover 101 is opened, and the cutter pressing member 201 is limited and locked.

[0054] The way to realize the protection linkage member 301 in this embodiment can adopt the way of detection linkage, and the specific implementation method is as follows:

[0055] A position detection sensor for monitoring the open or closed state of the printer cover 101 is provided on the printer cover 101 or the printer body 102 of this embodiment. An electric locking assembly is provided at a position of the printer cover 101 of this embodiment close to the cutter assembly. The label printer detects that the printer cover 101 is in an open state through the position detection sensor, controls the electric locking assembly to lock the cutter assembly, so that the cutter pressing member 201 cannot be pressed, and the cutter remains retracted inside the printer cover 101. The label printer detects that the printer cover 101 is in a closed state through the position detection sensor, controls the electric locking assembly to unlock the cutter assembly, and the cutter pressing member can be freely pressed to drive the cutter to cut paper.

[0056] Specifically, the position detection sensor of this embodiment can be a micro switch provided on the printer body 102. When the printer cover 101 is closed, the micro switch closes and sends a closing message. When the micro switch is not closed, it can be determined that the printer cover 101 is open. The electric locking assembly of this embodiment includes a locking drive motor and a locking member, and the locking drive motor drives the locking member to move to lock the cutter assembly and unlock the cutter assembly.

[0057] See Figure 4 As shown, the cutter pressing member 201 of this embodiment is installed on the printer cover 101 through a first spring 205, and the first spring 205 is used for resetting when the cutter pressing member 201 is pressed down. The cutter assembly of this embodiment includes a tool rest 203 fixedly connected to the cutter pressing member 201, and the cutter 204 is installed on the tool rest 203. The cutter assembly of this embodiment includes a paper pressing block connected to the cutter pressing member 201 through a second spring 208. The paper pressing block includes a first paper pressing portion 206 on one side of the cutter 204 and a second paper pressing portion 207 on the other side of the cutter 204. When pressing the cutter pressing member 201 to cut paper, the first paper pressing portion 206 and the second paper pressing portion 207 first contact the upper surface of the printing paper 500 in the paper feeding channel 400 of the printing paper to press both sides of the cutting position of the printing paper 500, and then continue to press down the cutter pressing member 201. The first paper pressing portion 206 and the second paper pressing portion 207 are resisted and no longer move downwards, which will compress the second spring 208, but the cutter 204 will continue to move downwards with the cutter pressing member 201 to cut the printing paper. The cutter assembly of this embodiment presses the paper on both sides of the cutter 204 through the first paper pressing portion 206 and the second paper pressing portion 207, which is more conducive to the cutter 204 to perform the paper cutting operation.

[0058] The printer cover 101 in this embodiment is rotatably connected to the printer main body 102 through a rotating shaft 103. Inside the printer main body 102 in this embodiment, a paper feed roller 600 is provided below the paper feed path 400 of the printing paper, and the paper feed of the printing paper 500 is realized by controlling and driving the paper feed roller 600; a thermal printing head (not shown) is provided inside the printer main body 102 in this embodiment within the paper feed path 400 of the printing paper for performing thermal printing on the printing paper. In addition, there is a paper bin (not shown) inside the printer main body 102 in this embodiment for placing a roll of printing paper, and the paper replacement operation can be performed by opening the printer cover 101 in this embodiment.

[0059] The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention.
