[0044] In the embodiment of the present application, the implementation principle of a printing device for corrugated cardboard box production is as follows: When the device is working, place the cardboard box above the placement rack 102. By running the motor 113, the output of the motor 113 rotates the motor rotating rod 112. The motor rotating rod 112 rotates the second rotating rod 111, and the second rotating rod 111 drives the conveyor belt 110 and the second conveyor belt 115 to rotate. The cardboard box placed on the placement rack 102 is sent to the next technological process through the conveyor belt 110. The conveyor belt can improve efficiency, reduce manual labor through automation, and lower production costs. Moreover, it can transport materials and products smoothly and continuously in the production line, reducing human operation errors and the risk of work-related injuries. Also, by rotating the first threaded rod 105 and the second threaded rod 108, while the first threaded rod 105 rotates, the first slider 104 will move along the thread on the surface of the first threaded rod 105 along the first chute 103 to realize the limitation of the cardboard box and make it move forward straight.

The adjustment gap can be adjusted to make the cardboard boxes pass through one by one, ensuring smooth operation in the production line and reducing possible accidents during operation. When the cardboard box moves forward along the conveyor belt 110 and the second conveyor belt 115 after being restricted by the limit block 204, the second motor 302 can be run. The output end of the second motor 302 rotates the bidirectional threaded rod 303, and the bidirectional threaded rod 303 rotates the limit baffle 304, causing the two side limit baffles 304 to move closer inward. The limit slide rod 310 contracts inward while limiting the limit baffle 304, and the cardboard box can be aligned along the limit baffle 304 and transported straight to the next process, accurately controlling the position of the materials or products on the conveyor belt to ensure that they reach the correct position at the correct time. This helps to improve production efficiency and product quality. When the cardboard box enters the printing machine 402 along the third conveyor belt 307 and is printed, the cardboard box will move downward along the roller rotating rod 404 and the roller 405 on the inner wall of the guide plate 403 at the outlet of the printing machine 402. Then, the printed cardboard box will slide down from the guide plate 403 into the storage box 409. When the storage box 409 is full, rotate the second limit block 411 outward. The second limit block 411 opens outward along the rotating rod five 410. Then, slide the storage box 409 along the bottom roller two 408 and take it out along the storage channel 406. Place the next storage box 409 in place and close the second limit block 411 to limit the storage box 409, which is convenient for collecting and replacing the storage box 409.
