The interior of the shell 201 is provided with a stopper 205. Block 205, a second spring 206 is provided on the outside of the block 205, a connecting block 207 is provided on the outer wall of the block 205, the housing 201 is slidably connected to the block 205, the slide bar 203 is adhesively connected to the two sets of mounting blocks 204, the housing 201 is fixedly connected to one side of the second spring 206, the housing 201 is slidably connected to the connecting block 207, the connecting blocks 207 are not connected to the mounting block 204, the block 205 is not connected to the connecting block 207, a flip cover 3 is fixed on the side of the connecting block 207 away from the block 205, and a connecting rod 5 is fixed to the inner wall of the paper box 1.

[0027] Pull the stopper 205 outward to separate the stopper 205 from the connecting block 207. The pressure on the first spring 202 is released, causing the connecting block 207 to pop out of the housing 201. The slide bar 203 serves to increase stability and at the same time drives one side of the flip cover 3 away from the outer wall of the paper tray 1. After the paper roll is placed on the top of the connecting rod 5, the flip cover 3 is pushed, driving the connecting block 207 into the interior of the housing 201. The first spring 202 is retracted by the pressure and accumulates force, and the stopper 205 prevents the connecting block 207 from popping out.

[0028] Reference Figure 3 and Figure 4 As shown, cleaning structures 4 are installed on both sides of the bottom of the flip cover 3. The cleaning structure 4 includes a gear 401, a belt 402, a special-shaped tooth 403, a rack 404, a slider 405, a brush 406 and a dirt collecting tank 407. The opposite sides of the gear 401 are installed on both sides of the bottom of the flip cover 3. The belt 402 is installed on the outside of the gear 401. The inner wall of the belt 402 away from the gear 401 is installed with a special-shaped tooth 403. The bottom end of the special-shaped tooth 403 is installed with a rack 404. The bottom surface of the rack 404 is welded with Brushes 406 are attached to the slider 405 and the opposite side of the rack 404. A dirt collecting groove 407 is provided at the bottom of the brush 406. The gear 401 is connected to the paper tray 1 through an axis. The gear 401 is rotatably connected to the flip cover 3. The gear 401 is meshed with the belt 402. The belt 402 is meshed with the special-shaped teeth 403. The special-shaped teeth 403 are meshed with the rack 404. The slider 405 is slidably connected to the paper tray 1. The bottom end of the brush 406 is in conflict with the paper tray 1 and is not connected. The dirt collecting groove 407 is slidably connected to the paper tray 1.

[0029] There is no need for separate manual cleaning. During the process of changing the roll of paper, the flip cover 3 is opened or closed, and the flip cover 3 drives the gear 401 to rotate inside the paper tray 1, thereby driving the brush 406 to sweep the dust and paper scraps at the bottom of the connecting rod 5 into the inside of the dirt collecting trough 407. When the dust is full, the sliding dirt collecting trough 407 can place it outside the paper tray 1, thereby realizing the function of the device to clean the paper tray 1.

[0030] In summary, if Figures 1-4As shown, when the barcode scale is in use, the stopper 205 is pulled to drive the second spring 206 to retract, so that the stopper 205 is separated from the connecting block 207. The pressure of the first spring 202 is released and the connecting block 207 is ejected through the mounting block 204. The connecting block 207 drives the top of the flip cover 3 away from the outer wall of the paper box 1. The bottom of the flip cover 3 rotates inside the paper box 1. The flip cover 3 drives the gear 401 to rotate. The gear 401 drives the special-shaped gear 403 to rotate through the belt 402. The special-shaped gear 403 drives the rack 404 to move. The rack 404 drives the slider 405 to move in the paper box. 1, and at the same time, the rack 404 drives the brush 406 to slide at the bottom of the paper tray 1, placing the paper roll on the top of the connecting rod 5, pushing the top of the flip cover 3, driving the connecting block 207 to enter the interior of the shell 201, and the second spring 206 and the first spring 202 are retracted under pressure. After stopping pushing, the second spring 206 returns to the relaxed state, driving the stopper 205 to contact the connecting block 207, so that the connecting block 207 is fixed to the inside of the shell 201, and sliding the dirt collecting trough 407 to the outside of the paper tray 1, so that the dust inside it can be cleaned.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
