[0020] Reference Figures 1-3 A cardboard box creasing device includes a main frame 1, a transmission assembly 101 installed on the inner wall of the main frame 1, positioning assemblies 2 installed on both sides of the main frame 1 for positioning the cardboard conveyed on the surface of the transmission assembly 101, and a pressing assembly 3 installed on the top of the main frame 1 for pressing the cardboard on both sides of the creasing. The device also includes:

[0021] The clamping assembly 3 includes a first connecting frame 301, which is fixedly installed on the top of the main frame 1. An electronic telescopic rod 302 is fixedly connected to the top of the first connecting frame 301. A connecting block 303 is fixedly connected to the bottom of the electronic telescopic rod 302. An indentation knife 304 is snapped into the bottom of the connecting block 303. A mounting frame 310 is fixedly connected to the side walls of the connecting block 303 on both sides of the indentation knife 304. A connecting plate 305 is rotatably connected to the inner wall of the mounting frame 310. A rotating roller 306 is rotatably connected to the end of the connecting plate 305. A spring 307 is fixedly connected between the connecting plate 305 and the mounting frame 310.

[0022] The inner wall of the mounting bracket 310 is rotatably connected to a rotating column 308, and a limiting plate 309 is fixedly connected to the side wall of the rotating column 308, and the limiting plate 309 and the side wall of the connecting plate 305 are in contact.

[0023] A nut is threaded onto the side wall of the outer rotating column 308 located on the mounting bracket 310. The nut is used to fix the rotating column 308.

[0024] It should be noted that: the conveying component 101 is used to convey the cardboard, and the positioning component 2 is used to eliminate wrinkles on the surface of the cardboard. During creasing, the drive electronic telescopic rod 302 moves the connecting block 303 downward. Before the creasing knife 304 at the bottom of the connecting block 303 creasing the cardboard, the rotating roller 306 at the end of the connecting plate 305 first comes into contact with the surface of the cardboard. As the connecting block 303 moves downward, the rotating roller 306 rolls outward from the mounting frame 310 on the surface of the cardboard, while the connecting plate 305 rotates upward from the mounting frame 310. This allows the rotating roller 306 to press the cardboard firmly without... It will create indentations on the cardboard and keep the cardboard between the rotating rollers 306 in a taut state until the indentation knife 304 indents the cardboard. The cardboard will not curl up. The spring 307 can cause the connecting plate 305 to drive the rotating roller 306 to return to its original position after indentation. The position of the limiting plate 309 can be adjusted by rotating the rotating column 308, thereby adjusting the position of the limiting plate 309 and the connecting plate 305, thus changing the angle between the connecting plate 305 and the cardboard, and adjusting the squeezing force of the rotating roller 306 on the cardboard when it contacts the cardboard surface. It is suitable for cardboard of different thicknesses.

[0025] Reference Figures 1-3 The positioning component 2 includes a second connecting frame 201, which is fixedly installed on both sides of the top of the main frame 1, and a threaded bolt 202 is threadedly connected to the top of the second connecting frame 201.

[0026] A rotating frame 203 is rotatably connected to the bottom of the threaded bolt 202, and a pressure roller 204 is rotatably connected to the inner wall of the rotating frame 203.

[0027] A limiting post 205 is fixedly connected to the top of the rotating frame 203, and the limiting post 205 penetrates the second connecting frame 201;

[0028] It should be noted that: rotating the threaded bolt 202 at the top of the second connecting frame 201 causes the threaded bolt 202 to drive the rotating frame 203 to slide down, thereby causing the pressure roller 204 on the inner wall of the rotating frame 203 to adhere to the cardboard on the surface of the transmission assembly 101. The pressure roller 204 can eliminate the wrinkles of the cardboard, which is convenient for subsequent creasing. The limiting post 205 can prevent the rotating frame 203 from rotating with the threaded bolt 202.

[0029] Reference Figures 1-3 The bottom of the connecting block 303 is provided with a T-shaped groove 4, and the indentation tool 304 is slidably connected to the T-shaped groove 4;

[0030] Both the positioning component 2 and the clamping component 3 are symmetrical about the center line of the main frame 1;

[0031] It should be noted that the embossing tool 304 can be replaced through the sliding connection between the T-shaped groove 4 and the embossing tool 304.

[0032] Operation method: The transmission component 101 is used to transmit cardboard. Rotating the threaded bolt 202 at the top of the second connecting frame 201 causes the threaded bolt 202 to drive the rotating frame 203 to slide down, thereby causing the pressure roller 204 on the inner wall of the rotating frame 203 to adhere to the cardboard on the surface of the transmission component 101. The pressure roller 204 can eliminate the wrinkles of the cardboard, which is convenient for subsequent creasing. The position of the limiting plate 309 can be adjusted by rotating the rotating column 308, thereby adjusting the position of the limiting plate 309 and the connecting plate 305, thereby changing the angle between the connecting plate 305 and the cardboard. Adjusting the squeezing force of the rotating roller 306 on the cardboard when it contacts the cardboard surface is suitable for cardboard of different thicknesses.

[0033] During creasing, the drive electronic telescopic rod 302 moves the connecting block 303 downward. Before the creasing knife 304 at the bottom of the connecting block 303 creasing the cardboard, the rotating roller 306 at the end of the connecting plate 305 first comes into contact with the surface of the cardboard. As the connecting block 303 moves downward, the rotating roller 306 rolls outward on the surface of the cardboard towards the mounting frame 310, while the connecting plate 305 rotates upward towards the mounting frame 310. This ensures that the rotating roller 306 presses the cardboard tightly without forming a creasing, and keeps the cardboard between the rotating rollers 306 in a taut state until the creasing knife 304 creasing the cardboard. The cardboard will not warp. The spring 307 allows the connecting plate 305 to drive the rotating roller 306 to return to its original position after creasing.
