[0054] Example

[0055] like Figures 1 to 8 As shown, this embodiment provides a printer with a cutter protection structure, including a main body component 1, a cover component 2, a cutter component 3 and a protective component 4, the main body component 1 is provided with an unlocking column 11; the cover component 2 is rotatably arranged on the main body component 1, and a first through hole 211 is provided on the cover component 2, and the first through hole 211 corresponds to the unlocking column 11. When the cover component 2 and the main body component 1 are opened and closed, the unlocking column 11 is suitable for inserting into and moving away from the first through hole 211; the cutter component 3 is arranged in the cover component 2, and the cutter component 3 is suitable for moving up and down; the protective component 4 is arranged in the cover component 2 and is located at both ends of the cutter component 3. Under the insertion action of the unlocking column 11, the protective component 4 has a non-limiting state separated from the cutter component 3, and a limiting state abutting against the cutter component 3.

[0056] In an embodiment of the present utility model, when the cover assembly 2 and the main body assembly 1 are closed, the unlocking column 11 passes through the first through hole 211 and moves the protective assembly 4 to disengage the protective assembly 4 from the cutter assembly 3, the cutter assembly 3 is released from the restriction, and the cutter assembly 3 cuts the printed label; when the cover assembly 2 is separated from the main body assembly 1, the unlocking column 11 disengages from the first through hole 211, the protective assembly 4 returns to its initial state, the protective assembly 4 abuts against the cutter assembly 3, and the protective assembly 4 limits the cutter assembly 3, so that the cutter assembly 3 cannot move, thereby ensuring the safety of the user's hands.

[0057] During the use of the label printer, when it is necessary to change labels, in order to prevent the hands from being cut by the cutter assembly, a protective assembly is required to limit the cutter assembly when the upper cover is opened. The existing protective assembly limits the cutter assembly by a torsion spring and a limiter, and this protective structure is relatively complicated to install, thereby affecting the assembly efficiency of the printer. In the present utility model, by providing the protective assembly 4, it is possible to separate the cover assembly 2 from the main assembly 1. That is, when the cover assembly 2 is opened, the protective assembly 4 limits the cutter assembly 3 to prevent the cutter assembly 3 from moving downward and cutting the user's hands. When the cover assembly 2 is closed, the protective assembly 4 is separated from the cutter assembly 3, and the protective assembly 4 cannot limit the cutter assembly 3, and the cutter assembly 3 cuts the printed labels.

[0058] Specifically, if Figure 3 As shown, the cover assembly 2 includes a first cover 21 and a second cover 22. The first cover 21 is rotatably mounted on the main assembly 1. The first cover 21 is provided with a first through-hole 211, into which the unlocking post 11 is adapted to be inserted. The second cover 22 is mounted on the first cover 21. When the first cover 21 abuts the main assembly 1, the unlocking post 11 is inserted into the first through-hole 211 and acts on the guard assembly 4, separating it from the cutter assembly 3. The cutter assembly 3 is freed from its restraint, enabling it to cut printed labels.

[0059] Further, if Figure 5As shown, the first cover 21 is further provided with a positioning post 212 and a limiting member 213. The limiting member 213 is provided at the edge of the first cover 21 and is close to the positioning post 212. The protective assembly 4 is mounted on the positioning post 212 and is arranged opposite to the limiting member 213. In the embodiment of the present utility model, the limiting member 213 is U-shaped, with its opening facing the positioning post 212. Of course, the limiting member 213 can be provided in other forms. This embodiment does not limit the setting form of the limiting member 213. Those skilled in the art can modify the setting form of the limiting member 213 according to actual conditions, as long as the same technical effect can be achieved.

[0060] In the present invention, there are two protective components 4, and the positioning columns 212 and the limiting members 213 are respectively arranged corresponding to the protective components 4. There are also two positioning columns 212 and the limiting members 213, both of which are arranged on the edge of one end of the first cover body 21 close to the cutter component 3.

[0061] Further, if Figure 5 As shown, the first cover 21 is further provided with a mounting seat 214, and the cutter assembly 3 is mounted on the mounting seat 214. The cutter assembly 3 is adapted to move up and down in the mounting seat 214. The up and down movement of the cutter assembly 3 can cut the printed label.

[0062] Further, if Figure 5 As shown, the mounting base 214 is provided with a second through-hole 2141 at one end near the guard assembly 4. The guard assembly 4 passes through the second through-hole 2141 and engages with the cutter assembly 3. When the first cover 21 abuts the main assembly 1, the unlocking post 11 is inserted into the first through-hole 211 and rotates the guard assembly 4, causing it to move out of the second through-hole 2141. Simultaneously, the guard assembly 4 is disengaged from the cutter assembly 3, releasing the restraint on the cutter assembly 3, and the cutter assembly 3 can then cut printed labels.

[0063] Specifically, if Figure 4 and Figure 5As shown, the protective assembly 4 includes a rotating member 41 and a first spring 42. The rotating member 41 is rotatably mounted on the positioning post 212. One end of the first spring 42 is engaged within the limiting member 213, and the other end abuts against the rotating member 41. Under the elastic force of the first spring 42, the rotating member 41 is adapted to limit the position of the cutter assembly 3. In the present invention, by directly engaging the first spring 42 within the limiting member 213 and then sleeved on the positioning post 212, the present invention is more convenient and quicker to assemble than conventional torsion spring installation, thereby improving the assembly efficiency of the printer.

[0064] Further, if Figure 6 As shown, a rotating hole 411 is provided at one end of the rotating member 41, and the rotating hole 411 is sleeved on the positioning column 212, and the rotating member 41 is suitable for rotating with the positioning column 212 as a fulcrum; the other end of the rotating member 41 is provided with an abutment portion 412, and the abutment portion 412 is suitable for passing through the second through hole 2141 to engage with the cutter assembly 3, and leaving the second through hole 2141 to disengage from the cutter assembly 3. When the cover assembly 2 and the main body assembly 1 are closed, the unlocking column 11 is inserted into the first through hole 211 and the rotating member 41 is rotated clockwise with the positioning column 212 as the fulcrum, so that the abutting portion 412 is away from the second through hole 2141, and at the same time, the abutting portion 412 is disengaged from the cutter assembly 3, and the cutter assembly 3 is released from the restriction, and then the cutter assembly 3 performs the cutting operation on the printed label; when the cover assembly 2 and the main body assembly 1 are separated, the unlocking column 11 leaves the first through hole 211, and the unlocking column 11 releases the restriction on the rotating member 41. The rotating member 41 rotates counterclockwise under the elastic force of the first spring 42, and the abutting portion 412 passes through the second through hole 2141 and engages with the cutter assembly 3. The rotating member 41 restricts the cutter assembly 3, and the cutter assembly 3 cannot move downward, thereby ensuring the safety of the user's hands.

[0065] Specifically, if Figure 7 and Figure 8As shown, the cutter assembly 3 includes a moving part 31, a paper pressing part 32, a cutter 33, a second spring 34 and a third spring 35. The moving part 31 is arranged on the mounting seat 214, and the moving part 31 is engaged with the abutting portion 412; the paper pressing part 32 is arranged on the moving part 31; the cutter 33 is arranged on the moving part 31 and is located on one side of the paper pressing part 32; the second spring 34 is arranged on the upper side of the paper pressing part, and one end abuts against the paper pressing part 32, and the other end abuts against the moving part 31; the third spring 35 is arranged on the lower side of the paper pressing part, and one end abuts against the paper pressing part 32, and the other end abuts against the first cover body 21. When the movable member 31 is pressed, the movable member 31 overcomes the elastic force of the second spring 34 and pushes the paper pressing member 32 downward so that the paper pressing member 32 abuts against the printed label. The movable member 31 is continuously pressed, and the movable member 31 overcomes the elastic force of the third spring 35 and pushes the cutter 33 to continue to move downward to cut the printed label.

[0066] Furthermore, the printer with the cutter protection structure also includes a pressing assembly 5, which is disposed on the second cover 22 and abuts against the cutter assembly 3. The pressing assembly 5 is adapted to drive the cutter assembly 3 to cut printed labels. Pressing the pressing assembly 5 pushes the movable member 31 downward, which in turn drives the cutter 33 downward, thereby cutting the printed labels.

[0067] The specific working process of the printer with the cutter protection structure provided by the utility model is as follows:

[0068] When the cover assembly 2 and the main body assembly 1 are closed, the unlocking column 11 passes through the first through hole 211, pushing the rotating member 41 to rotate clockwise, and at the same time, the abutting portion 412 disengages from the moving member 31 and moves away from the second through hole 2141, and the cutter assembly 3 is released from the restriction. By pressing the pressing assembly 5, the moving member 31 is pushed downward, and the moving member 31 drives the cutter 33 to move downward to cut the printed label; when the cover assembly 2 is separated from the main body assembly 1, the unlocking column 11 leaves the first through hole 211, and the unlocking column 11 releases the restriction on the rotating member 41. The rotating member 41 rotates counterclockwise under the action of the first spring 42, so that the abutting portion 412 passes through the second through hole 2141 and engages with the moving member 31, and the abutting portion 412 restricts the moving member 31, so that the moving member 31 cannot move downward, and the cutter 33 cannot move downward, thereby ensuring the safety of the user's hands when changing labels.

[0069] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
