The threaded rod 203 is threadedly connected to the interior of the support frame 201. The movable plate 204 is rotatably connected to the bottom of the threaded rod 203. Both ends of the movable plate 204 are slidably connected to the inner wall of the slide groove 202 and extend to the outside of the support frame 201. The reduction motor 205 is bolted to one side of the movable plate 204. The indentation roller 206 is coaxially arranged at the output end of the reduction motor 205. In use, by rotating the threaded column 304, the moving plate 204 slides up and down on the inner wall of the slide groove 202. Adjust the distance between the creasing roller 206 and the top of the operating table 1, start the reduction motor 205 to make the creasing roller 206 rotate, and then push the cardboard to the bottom of the creasing roller 206. At this time, the operating table 1 can provide support for the bottom of the cardboard, so that the depth of the creasing on the cardboard is consistent.

[0036] like Figure 2 and Figure 5 As shown, the limiting component 3 includes an adjusting groove 301, a limiting strip 302, an extension plate 303, a threaded post 304, and a nut 305. The four adjusting grooves 301 are all opened through the interior of the operating table 1. The four adjusting grooves 301 are arranged in pairs and opposite to each other. The two limiting strips 302 are arranged opposite to each other on the top of the four adjusting grooves 301. The two extension plates 303 are respectively fixedly connected to one side of the two limiting strips 302. The four threaded posts 304 are respectively fixedly connected to the bottom of the two extension plates 303 and slidably connected to the interior of the adjusting grooves 301. The four nuts 305 are respectively threadedly connected to the outer wall of the four threaded posts 304. The top of the nut 305 is tightly fitted to the bottom of the operating table 1. In use, the threaded post 304 can slide in the adjusting groove 301, thereby adjusting the position of the limiting strip 302 and the extension plate 303. By screwing the nut 305 into the outer wall of the threaded post 304 and making the top of the nut 305 fit tightly against the bottom of the operating table 1, the position of the extension plate 303 and the limiting strip 302 can be fixed. When creasing, the cardboard can be placed between the two limiting strips 302 to limit the cardboard and prevent the cardboard from deviating in position during creasing.

[0037] like Figure 2 and Figure 4As shown, the stabilizing assembly 4 includes an extension frame 401, a placement groove 402, springs 403, a stabilizing plate 404, a roller 405, and sliding rods 406.

The contracted spring 403 will continuously provide pressure to the moving cardboard to prevent the cardboard from warping and affecting subsequent creases, while the roller 405 can keep the cardboard moving smoothly.

[0038] like Figure 2 As shown, a mounting base 5 is fixedly connected to one side of the operating table 1, an electric push rod 6 is provided on one side of the mounting base 5, and a push plate 7 is provided on one side of the electric push rod 6. After the cardboard is placed between the two limit strips 302, the electric push rod 6 can be activated to make the push plate 7 push the cardboard to the creasing roller 206, reducing manual operation and avoiding safety hazards.

[0039] like Figure 1 As shown, a camera 8 is installed on the top of the operating table 1, and a single-chip microcontroller 9 and a display screen 10 are respectively installed on one side of the operating table 1. Both the camera 8 and the display screen 10 are electrically connected to the single-chip microcontroller 9. The camera 8 can continuously photograph the cardboard after creasing and transmit the data to the single-chip microcontroller 9. The single-chip microcontroller 9 processes the data, determines the number of cardboard pieces that have passed through, and finally transmits the data to the display screen 10, so that external workers can count the number of cardboard pieces after creasing.

[0040] like Figure 2 As shown, a movable groove 11 is provided on the top of the operating table 1, and a movable block 12 is slidably connected to the inner wall of the movable groove 11. The top of the movable block 12 is fixedly connected to the bottom of the push plate 7. When the push plate 7 moves, it will synchronously drive the movable block 12 to slide in the movable groove 11, thereby improving the stability of the push plate 7 during movement.

[0041] like Figure 2 As shown, the top of the operating table 1 has two scale lines 13, which are located at the bottom of the two extension plates 303 respectively. The limiting strip 302 and the extension plates 303 slide along the length of the scale lines 13. The scale lines 13 make it easy for workers to adjust the position of the limiting strip 302 and the extension plates 303 according to different sizes of cardboard.

[0042] Specifically, when using this cardboard creasing machine: Adjust the positions of the limiting strip 302 and extension plate 303 according to the scale line 13, based on the cardboard size. After adjustment, screw the nut 305 into the outer wall of the threaded post 304 to fix the limiting strip 302 and extension plate 303. By rotating the threaded post 304, the moving plate 204 slides up and down on the inner wall of the slide groove 202, adjusting the distance between the creasing roller 206 and the top of the operating table 1. Start the reduction motor 205 to rotate the creasing roller 206. Then, place the cardboard between the two limiting strips 302 and start the electric push rod 6 to push the cardboard to the bottom of the creasing roller 206. At this time, the operating table 1 can... The bottom of the cardboard is supported to ensure consistent crease depth. After the cardboard is creased, it moves to the bottom of the roller 405, causing the roller 405, stabilizing plate 404, and sliding rod 406 to move slightly upward and the spring 403 to contract. The contracted spring 403 continuously applies pressure to the moving cardboard to prevent it from warping and affecting subsequent creases, while the roller 405 keeps the cardboard moving smoothly. The camera 8 continuously captures images of the creased cardboard and transmits the data to the microcontroller 9. The microcontroller 9 processes the data, determines the number of cardboard pieces that have passed through, and finally transmits the data to the display screen 10 so that external workers can count the number of creased cardboard pieces.

[0043] All technical features in this embodiment can be freely combined according to actual needs.

[0044] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
