[0031] The working principle is as follows: First, the first electric telescopic rod 10 drives the spreading strips 11 to move to the appropriate position. Then, the corrugated carton to be spread is placed on the two sets of spreading strips 11. Then, the drive motor 4 drives the bidirectional threaded screw 5 to rotate, and the threaded rings 6 move on the bidirectional threaded screw 5. The two sets of threaded rings 6 move in opposite directions, thus spreading the carton. The existing device can spread the carton, but it is not convenient to lift the four corners of the bottom of the carton. Spreading the four corners allows the carton to form a stable bottom structure more quickly, reducing packaging time and improving production efficiency. Therefore, this needs to be improved. The second hook and loop fastener 20 is attached to the first hook and loop fastener 19, and the protective layer 21 is installed on the lifting block 13. Then, the lifting block 13 is pushed from top to bottom so that the bottom of the second assembly block 16 is attached to the top of the support block 15, and the first assembly block 14 and the second assembly block 16 are attached. Then, the threaded rod 18 is fixed into the threaded groove 17, and the lifting block 13 is installed on the second... At the output end of the electric telescopic rod 12, after the carton is opened, the second electric telescopic rod 12 drives the lifting block 13 to move, and the four sets of lifting blocks 13 lift and open the four corners of the carton. At the same time, the lifting blocks 13 can be disassembled and replaced. Corrugated carton manufacturers need to conduct small and medium-sized sample test runs. The inner wall dimensions of the carton are a mandatory inspection item upon arrival at the factory, so it is necessary to open it and then measure the carton. Different carton samples are different and require different measuring rulers. Therefore, it is necessary to store and facilitate the use of measuring rulers of different units. First, different measuring rulers 25 are placed in the card sleeve 23, and the rubber sealing ring 24 limits the measuring ruler 25. The label sleeve 27 is used to place the detailed label paper of the measuring ruler 25 on one side, so that the staff can quickly measure the unit of the measuring ruler 25. The protective cover 28 is attached to the top of the convenient box 22 by the magnetic block 29, which facilitates the storage of the measuring ruler 25 and makes it easy to take out and use the measuring ruler 25.
