The forming and fixing clamps 4 are respectively arranged correspondingly to the feeding folding unit 5, the first folding pre-pressing unit 6, the second folding pre-pressing unit 7, and the discharging folding unit 8. The feeding folding unit 5, the first folding pre-pressing unit 6, the second folding pre-pressing unit 7, and the discharging folding unit 8 are respectively installed between the folding turntable 2 and the turntable support 3.

[0034] The folding turntable 2 is installed on the upper end of the folding machine frame 1 and located at the lower end of the turntable support 3. The feeding folding unit 5, the first folding pre-pressing unit 6, the second folding pre-pressing unit 7, and the discharging folding unit 8 are respectively installed around the folding turntable 2 in a circular array. With the axis of the folding turntable 2 as the center, the distance between the axis of the folding turntable 2 and the feeding folding unit 5, the first folding pre-pressing unit 6, the second folding pre-pressing unit 7, or the discharging folding unit 8 is equal.

[0035] In use, the feeding folding unit 5, the first folding pre-pressing unit 6, the second folding pre-pressing unit 7, and the discharging folding unit 8 rotate clockwise or counterclockwise around the axis of the folding turntable 2 to perform circular motion; thereby realizing the folding step in the packaging box and completing the folding action of the entire packaging box.

[0036] The folding process of the folding box machine applied for in this case is as follows: First, the sliding bracket 506 moves up and down along the moving module 505, driving the cardboard suction plate assembly 507 on the sliding bracket 506 to move up and down. The cardboard suction plate assembly 507 moves upward to suck up the flat cardboard on the turntable bracket 506 and move it downward, placing the flat cardboard into the corresponding forming and fixing fixture 4 under the feeding folding box unit 5. The forming and fixing fixture 4 then guides the flat cardboard in the hopper to form a semi-finished packaging box, thus completing the feeding process. Please refer to [reference needed]. Figure 11 Steps a1 and a2.

[0037] As the folding turntable 2 rotates, the forming and fixing fixture of the semi-finished packaging box moves to the position of the first folding pre-pressing unit 6. Driven by the first pre-pressing drive source 602, the first pre-pressing moving center rod 603 moves downwards, simultaneously driving the outer end faces of the first pre-folding elastic pressure plates 607 on both sides to move downwards. The first pre-folding elastic connecting plate 605 generates a component force to pre-press the folded edges on both sides of the semi-finished packaging box. Simultaneously, the first flattening pressure plate 609 flattens the bottom of the semi-finished packaging box, thus completing the first pre-pressing process. Please refer to [reference needed]. Figure 11 Steps a2 to a5.

[0038] Under the rotation of the folding turntable 2, the forming fixture 4, after being formed in the first pre-pressing process, moves to the position of the second folding pre-pressing unit 6. Driven by the second pre-pressing drive source mechanism 702, the second pre-pressing moving center rod 703 moves downwards, causing the second transverse folding pushing block 706 and the folding elastic frame 705 to move downwards. The second longitudinal folding pushing block 707, located on the end face of the second transverse folding pushing block 706, and the folding elastic pressure plate 713, located at the lower end of the folding elastic frame 705, cooperate to press and fold. The second transverse folding pushing block 706 folds and presses against the folding elastic pressure plate 713 outwards, achieving a second pre-pressing action on the folded edges of the semi-finished packaging box, thus completing the second pre-pressing process. Please refer to [link / reference needed]. Figure 11 Steps a5 to a10.

[0039] Under the rotation of the folding box turntable 2, the forming and fixing fixture after the second pre-pressing process moves to the position of the discharge folding box unit 8. First, driven by the transfer power source 808, the top plate 806 is driven to move upward, pushing the finished packaging box placed inside the forming and fixing fixture 4 upward. Then, the material picking vacuum suction cup assembly 813 picks up the ejected finished packaging box and moves it to the position above the discharge ladder 803. The release action drives the finished packaging box to be placed on the discharge ladder 803. Then, as the discharge ladder moves to the designated position, the discharge folding process is completed.

[0040] Thus, the feeding process, the first folding and pre-pressing process, the second folding and pre-pressing process, and the unloading and folding process are completed in sequence.

[0041] During the entire folding process described above, the first folding pre-pressing unit 6 and the second folding pre-pressing unit 7 apply a downward or inward force to the area of ​​the paper box formed by the feeding folding unit 5 that requires folding. This force is applied by the elastic pressure plate to flatten the required folding edge towards the inside of the packaging box, achieving the desired folding shape. This solves the technical problems of the edges not fitting properly or collapsing during folding.

[0042] The preferred embodiments of this utility model have been described above with reference to the accompanying drawings, but this does not limit the scope of the utility model's technical solution. Any modifications, equivalent substitutions, and improvements made by those skilled in the art without departing from the scope of protection and substantive rights of this utility model's technical solution shall be within the scope of the utility model's technical solution.
