[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1-5 As shown, embodiments of the present invention include:

[0020] A corrugated cardboard box forming device includes a platform 1, a support channel 2, a shifting carrier 3, a corrugated sheet pressing forming cylinder 4, four-sided initial forming guide plates 5, a long-side inner page initial folding strip 6, a side support mechanism 7, and a long-side inner page pressing and folding cylinder 8. The platform 1 is provided with the support channel 2, along which a first station 21, a second station 22, and a third station 23 are arranged. The shifting carrier 3 is matched and matched below the support channel 2. The corrugated sheet pressing forming cylinder 4 is provided above the first station 21. At station 21, a four-sided initial forming guide plate 5 is provided around the transposition carrier 3. The corrugated sheet pressing forming cylinder 4 descends through the four-sided initial forming guide plate 5 and is pushed into the transposition carrier 3. Between station 21 and station 22, a long-side inner page initial folding strip 6 is arranged in the same direction as the supporting flow channel 2. At station 22, a side support mechanism 7 is provided connected to the tail end of the long-side inner page initial folding strip 6. Above station 22, a long-side inner page pressing and folding cylinder 8 is provided to push into the transposition carrier 3.

[0021] The shifting carrier 3 consists of a pneumatic optical axis slide 31 and two alternating material cavities 32 arranged on the pneumatic optical axis slide 31, which alternately connect to the first station 21, the second station 22, and the third station 23 in a single shifting action. Each alternating material cavity 32 is provided with a pair of long side guard plates 33 for cardboard boxes, and a negative pressure suction cup 34 is provided between the long side guard plates 33 for cardboard boxes.

[0022] Furthermore, the supporting channel 2 is composed of a pair of strip-shaped angle steels, which are used to support the wide sides of the bottom of the corrugated cardboard box.

[0023] Furthermore, the long side guard plate 33 of the paper box is divided into a first guard plate 331 and a second guard plate 332 arranged opposite to each other. The first guard plate 331 is divided into a static guard plate 334 of an active guard plate 333 arranged vertically. The active guard plate 333 is connected to a horizontally arranged long side inner page folding cylinder 335. The upper edges of the active guard plate 333 and the second guard plate 332 are both outwardly curved.

[0024] Furthermore, the long-side inner page initial folding strip 6 is horizontally arranged at the same height as the lower edge of the active guard plate 333, which is used to press the long side of the paper box.

[0025] Furthermore, the side support mechanism 7 consists of two side support telescopic cylinders 71 symmetrically arranged on the outside of the support channel 2, and the side support telescopic cylinders 71 are equipped with position guide forks 72.

[0026] Furthermore, a wide-edge inner page pneumatic initial folding plate 9 is provided at the three workstations 23, and a liftable wide-edge inner page dropping and pressing block 73 is provided above the three workstations 23.

[0027] In addition, the corrugated sheet pressing and forming cylinder 4 can be designed as a segmented telescopic structure. That is, it can be composed of a primary lifting cylinder and a secondary lifting cylinder cascaded under the primary lifting cylinder. The secondary lifting cylinder is connected to a horizontally arranged cardboard box bottom liner. The cardboard box bottom liner is integrated with a negative pressure upper suction cup. The cardboard box bottom liner is surrounded by a non-contact cardboard box four-sided pre-folding liner connected to the primary lifting cylinder.

[0028] The four-sided initial forming guide plate 5 surrounds and matches the outline of the four-sided pre-folded backing plate of the paper box. The upper edges of the four-sided initial forming guide plate 5 are all outwardly curved. A pair of long-side pre-folded guide rods are horizontally arranged between the four-sided initial forming guide plates 5. The long-side pre-folded guide rods are higher than the four-sided initial forming guide plates 5, and the distance between the long-side pre-folded guide rods is greater than the distance between the four-sided initial forming guide plates 5.

[0029] The long-side inner page pressing and folding cylinder 8 consists of a long-side lifting cylinder and two sets of external support locking cylinders cascaded below the long-side lifting cylinder. The lower end of the long-side lifting cylinder is provided with a long-side pressing block, and the external support locking cylinder is provided with an external support plate. The external support plates are arranged horizontally back to back.

[0030] like Figure 1 and 5 As shown, the corrugated sheet pressing and forming cylinder 4, the long side inner page pressing and folding cylinder 8, and the wide side inner page dropping and pressing block 73 are suspended on the upper suspension 100 in sequence corresponding to the first, second, and third workstations, and are all lifted and lowered by independent cylinders. Figure 1The corrugated cardboard sheet is sucked up by a vacuum suction cup on the corrugated sheet pressing cylinder 4. As the cylinder 4 descends, the cardboard sheet is squeezed between the long side guard plates 33, forming a partially shaped box. To improve the reliability of the pressing process, different four-sided initial forming guide plates 5 are assigned to each side and lug of the box. At this time, the long and wide inner pages of the box are vertically exposed. Next, these inner pages need to be folded into the box. The corrugated cardboard sheet has snap-fit ​​holes for these inner pages. Therefore, the function achieved at the second station is to fold the long side inner pages and snap them in place. See details. Figure 4 The side-support telescopic cylinder 71 first supports the side of the cardboard box to prevent it from veering off course, then... Figure 5 As shown, the long side inner page pressing and folding cylinder 8 moves downward, pressing the inner page in and supporting it outward, thus installing the long side. Similarly, the folding and locking of the wide side inner page is achieved at the third station.

[0031] In summary, this invention provides a corrugated cardboard box forming equipment that addresses the problems of large scale and complex structure in traditional assembly line processing equipment. By independently placing the inner page folding part on the upper side of the flow channel and independently placing the shaping guide plate along the platform flow channel, the inner page folding is achieved by the cooperation of the pneumatic optical axis slide table and the long side inner page initial folding pressure strip 6, thereby improving the compactness of the equipment and increasing the integration of the mechanism.

Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
