The output end of the hydraulic rod 6 extends below the top plate 4 and is fixedly installed with a pressing plate 7. A pressing block 8 is fixedly installed at the center of the bottom surface of the pressing plate 7. By starting the hydraulic rod 6, the pressing plate 7 is driven to move downward, and the pressing plate 7 drives the pressing block 8 to move downward, which is convenient for pressing and forming the carton cardboard. An adjusting assembly is installed on the upper surface of the placing plate 3 for adjusting the position of the cardboard. An ejecting assembly is installed inside the forming box 2 to facilitate ejecting the formed carton from the forming box 2. The ejecting assembly includes an ejecting plate 17 slidably arranged inside the forming box 2. Connecting plates 18 are fixedly installed on both sides of the ejecting plate 17.

[0022] Further, slopes are provided on the inner walls at the openings on the upper surface of the forming box 2, facilitating the formation of creases around the cardboard and on its bottom surface when pressing the cardboard, thus facilitating the pressing of the cardboard into a carton. Communication grooves 21 are provided on both sides of the forming box 2, and the connecting plates 18 extend to the outside of the forming box 2 through the communication grooves 21, facilitating the up-and-down movement of the connecting plates 18 and the normal progress of the ejection operation.

[0023] Refer to Figures 1-3 , the adjusting assembly includes two connecting guide rods 9 inserted through the placing plate 3. Auxiliary pressing plates 10 are fixedly installed at the tops of the connecting guide rods 9. Working openings 16 are provided at the centers of the auxiliary pressing plates 10. A group of guide rods 15 are hinged on both sides of each auxiliary pressing plate 10. Push plates 12 are hinged at the bottoms of each group of guide rods 15. A plurality of springs 13 are fixedly connected to the opposite surfaces of the two push plates 12. Buffer plates 14 are fixedly connected to one ends of the springs 13.

[0024] By starting the hydraulic rod 6, the pressing plate 7 is driven to move downward and contact the auxiliary pressing plate 10, pushing the auxiliary pressing plate 10 to move downward. The auxiliary pressing plate 10 pushes the push plate 12 to slide on the sliding frame 11 through the guide rods 15. The push plate 12 pushes the buffer plate 14 to slide towards the center of the placing plate 3 through the springs 13, adjusting the position of the carton cardboard to the center of the placing plate 3. At the same time, the buffer plate 14 can also perform a certain limit fixation on the position of the carton cardboard, preventing subsequent sliding of the cardboard from affecting the operation of the device and facilitating the subsequent pressing of the cardboard to form the box body.

[0025] By providing springs between the push plate 12 and the buffer plate 14, a certain buffering effect can be achieved, preventing the push plate 12 from rigidly pushing the buffer plate 14 into contact with the side of the cardboard and damaging the cardboard, thus affecting the production quality of the carton.

[0026] Among them, the size of the pressing block 8 matches the inside of the forming box 2. The length and width of the pressing plate 7 are both larger than the length and width of the working opening 16, facilitating the pressing plate 7 to drive the auxiliary pressing plate 10 to move downward and ensuring the normal operation of the device.

[0027] Further, each group of guide rods 15 consists of two and is arranged on both sides of the connecting guide rod 9. A sliding frame 11 is installed on the upper surface of the placing plate 3. One ends of the push plates 12 are sleeved on the outer surface of the sliding frame 11 and are slidably connected to the sliding frame 11, facilitating the limitation of the movement of the push plates 12 and ensuring the normal operation of the device.

[0028] Refer to Figure 4 , mounting plates 19 are fixedly installed at the bottoms of the connecting guide rods 9. Second springs 20 are fixedly installed on the upper surface of the base 1. The tops of the second springs 20 are fixedly connected to the mounting plates 19. One ends of the connecting plates 18 are fixedly connected to the mounting plates 19.

[0029] After the pressing is completed, the hydraulic rod 6 drives the pressing plate 7 and the pressing block 8 to move upward and move out from the inside of the forming box 2. The pressing plate 7 is separated from the auxiliary pressing plate 10. The second spring 20 will drive the mounting plate 19 to move upward through its own elastic force. The mounting plate 19 drives the ejector plate 17 to move upward through the connecting plate 18, which facilitates ejecting the cardboard box inside the forming box 2, facilitating the staff to take out the processed cardboard box, and improving the production efficiency of the cardboard box. When the mounting plate 19 moves upward, it will also drive the auxiliary pressing plate 10 and the buffer plate 14 back to their original positions to facilitate the next operation.

[0030] Working principle: For this cardboard box forming device, when in use, first place the cardboard of the cardboard box on the placing plate 3, and then start the hydraulic rod 6 to drive the pressing plate 7 to move downward to contact the auxiliary pressing plate 10, and push the auxiliary pressing plate 10 to move downward. The auxiliary pressing plate 10 pushes the push plate 12 to slide on the sliding frame 11 through the guide rod 15. The push plate 12 pushes the buffer plate 14 to slide towards the center of the placing plate 3 through the spring 13, adjusting the position of the cardboard of the cardboard box to the center of the placing plate 3. At the same time, the buffer plate 14 can also limit and fix the position of the cardboard of the cardboard box to a certain extent, preventing the subsequent sliding of the cardboard from affecting the operation of the device and facilitating the subsequent pressing of the cardboard to form the box body.

[0031] When the auxiliary pressing plate 10 moves downward, it will also drive the mounting plate 19 to move downward through the connecting guide rod 9. The mounting plate 19 compresses the second spring 20 and drives the connecting plate 18 to move downward. The connecting plate 18 drives the ejector plate 17 to move downward, facilitating the emptying of the inside of the forming box 2. Then the hydraulic rod 6 continues to drive the pressing plate 7 to move downward. The pressing plate 7 drives the pressing block 8 to move downward to press the cardboard and push the cardboard into the inside of the forming box 2. The four sides and the bottom surface of the cardboard are folded to form creases, facilitating pressing the cardboard into a cardboard box.

[0032] After the pressing is completed, the hydraulic rod 6 drives the pressing plate 7 and the pressing block 8 to move upward and move out from the inside of the forming box 2. The pressing plate 7 is separated from the auxiliary pressing plate 10. The second spring 20 will drive the mounting plate 19 to move upward through its own elastic force. The mounting plate 19 drives the ejector plate 17 to move upward through the connecting plate 18, which facilitates ejecting the cardboard box inside the forming box 2, facilitating the staff to take out the processed cardboard box, and improving the production efficiency of the cardboard box. When the mounting plate 19 moves upward, it will also drive the auxiliary pressing plate 10 and the buffer plate 14 back to their original positions to facilitate the next operation.
