When it is necessary to take out the paper stuck in the paper feeding path or take out and replace the long label paper in the paper feeding path, press the printing plate 200 downward to rotate the printing plate 200 downward around the mounting part 110 to open the paper feeding channel, and automatically The locking pin 311 moves from the free end 211 to the self-locking end 212 due to the action of the torsion spring 313, and locks the printing plate 200 to keep the paper passage open, which is convenient for the user to take out the paper in the paper passage and realize quick paper change; Then, press the printing plate 200 again, the self-locking pin 311 moves from the self-locking end 212 to the free end 211 under the action of the torsion spring 313, and the printing plate 200 rotates upward around the mounting portion 110 under the action of the elastic member 320 to close the the paper path and remain closed for printing again.

Embodiment 2:

Referring to FIGS. 6 to 9 , the difference from the previous embodiment is that the locking portion is set as a support shaft, fixedly connected to the side plates on both sides of the middle of the printing board 200 , and protrudes from the side plates. It can be understood that the locking portion is The part can also be the protruding end of the protruding side plate, as long as it can bear the weight of the printing plate 200. The locking mechanism 300 includes a cam plate 330 and an operating lever 340 that are rotatably arranged on the side wall of the body 100. The cam plate 330 is connected to the The operating rod 340 is rigidly connected, and the specific cam plate 330 and the operating rod 340 form an included angle of 90°, and the extension end of the support shaft abuts on the cam board 330; the connection point between the operating rod 340 and the body 100 is the lever point, According to the lever principle, when the operation lever 340 is pressed down, the cam plate 330 rotates following the operation lever 340, the cam plate 330 moves the extended end of the support shaft to the top of the cam plate 330, and drives the printing plate 200 to move up to close the paper path At the same time, the extended end of the support shaft can stably abut on the top of the cam plate 330 to ensure normal printing; when the operating lever 340 is pulled up, the cam plate 330 rotates along with it, and the extended end of the support shaft extends from the cam plate 330. The top slides down to the angle between the cam plate 330 and the operating rod 340, and stably contacts the angle, the printing plate 200 moves downward, and the paper passage is opened, which is convenient for the user to take out the paper in the paper passage.

6 , further, the cam plate 330 is provided with a first stepped portion 331 , the first stepped portion 331 is protruded and provided with a second stepped portion 332 , the first stepped portion 331 is set flat, and the first stepped portion 331 is used for bearing support When the operating lever 340 is pressed down, the cam plate 330 moves the protruding end of the support shaft upward from the included angle to the top of the cam plate 330, the second step portion 332 can prevent the support shaft from slipping off the other end of the cam plate 330, Make sure to close the paper path steadily.

Further, the first stepped portion 331 adopts a circular arc transition, so that the extension end of the support shaft slides more smoothly between the included angle and the top of the cam plate 330, which facilitates opening or closing the paper feeding channel.

6, further, an indication switch is provided, and the indication switch is electrically connected to a warning light (not shown in the figure). Specifically, the indication switch is arranged on the side panel of the printer body 100, and is located below the operation lever 340, and is pressed down. When the operation lever 340 closes the paper path, the operation lever 340 simultaneously closes the indicator switch, and the warning light goes out, indicating that the printer can work normally; when the operation lever 340 is pulled up to open the paper path, the operation lever 340 simultaneously turns the indicator switch off. On, the warning light is on, indicating that the printer suspends work. Setting the indicating switch and warning light can remind the user of the current state of the printing board 200 to avoid misoperation.

When it is necessary to take out the paper stuck in the paper path or take out and replace the long label paper in the paper path, pull up the operation lever 340 to make the protruding end of the support shaft slide down from the top of the cam plate 330 to the position between the cam plate 330 and the cam plate 330. The operating lever 340 is located at the included angle, and is stably abutted at the included angle, the printing plate 200 moves down, and the paper feeding channel is opened, which is convenient for the user to take out the paper in the paper feeding channel and realize quick paper change. After the paper is taken out, press down Operating the lever 340, the cam plate 330 moves the protruding end of the support shaft up from the included angle to the top of the cam plate 330, and stably abuts the top of the cam plate 330, the printing plate 200 moves up, the paper feeding channel is closed, and it can be used again to print.

The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned embodiments. Within the scope of knowledge possessed by those of ordinary skill in the technical field, various modifications can be made without departing from the purpose of the present invention. kind of change.
