[0002] After printing and die-cutting, cardboard boxes need to have fold lines rolled out on them, and then the boxes are folded into shape according to the fold lines.

[0003] The patent with authorization announcement number CN210453926U provides a post-printing creasing machine for cartons, including a belt conveyor and a creasing device disposed on one side of the belt conveyor. The belt conveyor has multiple conveyor belts and two guide plates are provided on one side of the belt conveyor, with a guide channel separated by the two guide plates. It also includes a first gantry fixedly connected to the frame of the belt conveyor and multiple sets of heat and humidity devices installed on the first gantry. Each set of heat and humidity devices is disposed in the gap between two adjacent conveyor belts.

[0004] Although the existing technical solutions mentioned above can prevent the carton from cracking by first wetting the area to be creasing it before creasing, the existing carton printing creasing equipment cannot adjust the pressure of the creasing roller according to the thickness of the carton. Excessive creasing can easily cause damage to the direction, while insufficient pressure will make it difficult to assemble.

[0005] In view of this, we propose an integrated carton printing and creasing machine with adjustable pressure. Utility Model Content

[0015] 3. Beneficial effects

[0016] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0017] (1) This application is equipped with an adjustment component. After the drive motor is started, the connecting rod drives the two worm gears to rotate synchronously, so that the worm wheel rotates and the threaded rod rotates synchronously, which will drive the sliding block to move vertically. The two sliding blocks cause the two ends of the static pressure roller assembly to rise and fall synchronously, changing the distance between the static pressure roller assembly and the dynamic pressure roller assembly, thereby changing the pressure magnitude. This allows for creasing of cartons of different thicknesses, making folding easier and reducing damage.

[0018] (2) This application is equipped with a positioning component. By rotating the rotating disk, the bidirectional lead screw rotates, which drives the two moving parts to move relative to each other. This can limit the position of the cardboard and position the cardboard to the center position. The rotating disk can be replaced by a motor. The auxiliary rod is mainly used to assist the horizontal movement of the positioning rod and position the cardboard to the center, which facilitates accurate printing operations.

Detailed Implementation

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] Please see Figure 1-4This utility model provides an embodiment of an adjustable pressure carton printing and creasing integrated machine, including a printing and creasing integrated machine 110, a positioning component 200, and an adjusting component 300. A conveyor belt 113 is rotatably mounted inside the top of the printing and creasing integrated machine 110. Support back plates 120 are symmetrically arranged at one end of the printing and creasing integrated machine 110. A moving pressure roller assembly 122 and a stationary pressure roller assembly 121 are arranged parallel inside the two support back plates 120. Crimping rings are evenly arranged on the surfaces of the stationary pressure roller assembly 121 and the moving pressure roller assembly 122. A track frame 111 is mounted at the top of the printing and creasing integrated machine 110, and a printing module 115 is slidably mounted inside the track frame 111. A track frame 111 is located on one side of the track frame 111. An electric push rod 112 is provided, with one side of the electric push rod 112 connected to the side of the printing module 115. Threaded rods 314 are threadedly installed inside two sliding blocks 313, and worm gears 316 are provided at the top of the threaded rods 314. A worm gear 311 is meshed on one side of the worm gear 316. A connecting rod 312 is provided on one side of the two worm gears 311, and a drive motor 310 is connected to one side of the worm gear 311. An adjusting assembly 300 is provided inside the two support back plates 120. The adjusting assembly 300 includes a sliding rail 315 that conforms to the support back plate 120. A sliding block 313 is slidably disposed inside the sliding rail 315, and one side of the sliding block 313 is connected to one side of the static pressure roller assembly 121. (Reference) Figure 4 After the drive motor 310 starts, it drives the two worm gears 311 to rotate synchronously through the connecting rod 312, causing the worm wheel 316 to rotate. The threaded rod 314 rotates synchronously, which drives the sliding block 313 to move vertically. The two sliding blocks 313 cause the two ends of the static pressure roller assembly 121 to rise and fall synchronously, changing the distance between it and the moving pressure roller assembly 122, thereby changing the pressure. This allows for creasing of cartons of different thicknesses, facilitating folding and reducing damage.

[0027] Furthermore, the positioning component 200 is disposed at the output end of the conveyor belt 113. The positioning component 200 includes a bidirectional lead screw 212 fixedly disposed inside the printing and creasing machine 110. Moving parts 214 are symmetrically threaded on both sides of the bidirectional lead screw 212, and a positioning rod 211 is disposed at the top of the moving parts 214. One end of the bidirectional lead screw 212 is connected to a rotating disk 210, and an auxiliary rod 213 is parallel to the bottom end of the bidirectional lead screw 212. The bottom of the moving parts 214 is slidably connected to the outer side of the auxiliary rod 213. (Reference) Figure 3 By rotating the rotating disk 210, the bidirectional lead screw 212 rotates, driving the two moving parts 214 to move relative to each other, which can limit the position of the cardboard and position the cardboard to the center position. The rotating disk 210 can be replaced by a motor. The auxiliary rod 213 is mainly used to assist the horizontal movement of the positioning rod 211 to position the cardboard to the center, which facilitates precise printing operations. After printing, the cardboard enters the creasing assembly through the output end of the conveyor belt 113 and is discharged after creasing.

[0028] Furthermore, a fiber optic sensor 114 is installed in the middle of one side of the track frame 111. The physical property type fiber optic sensor utilizes the sensitivity of optical fiber to environmental changes to convert the input physical quantity into a modulated optical signal. Its working principle is based on the optical modulation effect of optical fiber. After the fiber optic sensor 114 detects the cardboard, it causes the conveyor belt 113 to stop printing.

[0029] In summary, the adjustable pressure carton printing and creasing machine disclosed in this application operates by rotating the rotating disk 210, causing the bidirectional lead screw 212 to rotate and driving the two moving parts 214 to move relative to each other. This restricts the position of the cardboard, positioning it at the center. The rotating disk 210 can be replaced by a motor. The auxiliary rod 213 mainly assists the horizontal movement of the positioning rod 211, positioning the carton towards the center for precise printing. After printing, the cardboard enters the creasing assembly through the output end of the conveyor belt 113 and is discharged after creasing. After the drive motor 310 starts, it drives the two worm gears 311 to rotate synchronously through the connecting rod 312, causing the worm wheel 316 to rotate. The synchronous rotation of the threaded rod 314 drives the sliding block 313 to move vertically. The two sliding blocks 313 cause the two ends of the static pressure roller assembly 121 to rise and fall synchronously, changing the distance between it and the moving pressure roller assembly 122, thereby changing the pressure. This allows for creasing of cartons of different thicknesses, facilitating folding and reducing damage.
