Two side panels 4.3 that can move away from or approach the bottom support plate 4.2 are symmetrically arranged on the base 4.1 and on both sides of the bottom support plate 4.2. The upper end of each side panel 4.3 is also fixedly connected with a shoveling block 4.4 perpendicular to the side panel and facing the bottom support plate 4.2, so that the two side edges of the box body piece themselves can be overlapped and formed by the action of the shoveling plate; next to one side of the double-station rotary bracket 1, a box body forming workbench 2 for pre-placing the box body piece 100 is provided in cooperation, and a hollow groove 7 for the bottom support plate 4.2, the inner support frame 5 and the upper pressing frame 6 to press down is opened on the box body forming workbench 2 corresponding to the position of the box pressing assembly.

[0028] The side plate 4.3 is fixedly connected to the movable end of a cylinder fixedly connected to the base 4.1 through a bracket, so that its movement is achieved by the drive of the cylinder and is guided by a guide rod passing through the bracket.

[0029] The support frame 5 inside the box is driven by a linear drive mechanism arranged on the double-station rotary bracket 1 so as to be able to move up and down along the double-station rotary bracket 1. The upper pressure frame 6 is driven by a linear drive mechanism fixedly connected to the support frame 5 inside the box so as to be able to move up and down relative to the support frame 5 inside the box, thereby being able to move up and down along the double-station rotary bracket 1.

[0030] The linear drive mechanism that drives the support frame 5 inside the box to move up and down along the double-station rotary bracket 1 is a screw nut sleeve linear drive mechanism 1.1 driven by a motor arranged on the double-station rotary bracket 1. The upper pressure frame 6 is driven by a cylinder fixedly connected to the support frame 5 inside the box to achieve up and down movement relative to the support frame 5 inside the box.

[0031] Next to the hollow groove 7 of the box body forming workbench 2, a limiting mechanism 3 for positioning the box body piece is provided.

[0032] Next to the other side of the double-station rotary support 1, there are provided an automatic bottom-attaching mechanism for attaching the bottom film 200 to the outer end of the inner box support frame 5 and an automatic unloading mechanism for removing the completed box body 300 from the inner box support frame 5. The automatic bottom-attaching mechanism and the automatic unloading mechanism can be arranged one above the other.

[0033] The automatic bottom pasting mechanism is a patch robot or a flip feeding and pasting mechanism.

[0034] The automatic unloading mechanism is a unloading robot or a lever unloading mechanism. When unloading with the lever unloading mechanism, when the inner support frame carrying the completed box body 300 is moved to the unloading mechanism, the unloading lever acts on the top or bottom of the box body to release the box body mounted on the inner support frame and unload it. Furthermore, the lever is driven back and forth by a linear drive mechanism.

[0035] The forming principle of the half-type packaging box body:

[0036] The double-station rotary bracket fits the upper box bottom sheet to the outer end of the inner box support frame 5 on one side and cuts the formed box body. On the other side (i.e., the side where the box body forming workbench is located), the upper box body sheet is closely fitted to the four side surfaces of the inner box support frame 5. Thus, the box bottom sheet and the box body sheet are combined to form a half-type packaging box body. The specific forming process of the half-type packaging box body is as follows:

[0037] Working process:

[0038] The rotating bracket carries the box pressing assembly and can complete the pasting of the box bottom film on the outer end surface of the box inner support frame of the box pressing assembly on the side opposite to the box body forming workbench, and complete the unloading of the half-type packaging box body formed on the box inner support frame.

[0039] The rotating bracket carries the box pressing assembly, and can complete the covering of the upper box body piece on the four sides of the inner box support frame of the box pressing assembly on the side where the box body forming workbench is located. The box body piece cooperates and fits with the box bottom piece that has been attached to the outer end surface of the inner box support frame to complete the forming of the half-type packaging box body.

[0040] The specific working process is as follows:

[0041] Next to the double-station rotary bracket, on the side opposite to the box body forming workbench, a box bottom film 200 is attached to the outer end of the box inner support frame 5 of the box pressing assembly on this side, and the attached box bottom film 200 is fixed by the suction cup located on the outer end of the box inner support frame 5;

[0042] Then the double-station rotary bracket rotates to bring the group of box pressing components with a box bottom film attached to the outer end of the inner box support frame 5 to the side where the box body forming workbench is located; on this side, the bottom support plate on the bottom bracket of the group of box pressing components rises to a position flush with the hollow groove on the box body forming workbench 2. On the box body forming workbench 2, a box body piece with four sides, with creases pre-folded between two adjacent sides, has been placed in advance by manual or mechanical means, with the second side of the box body piece facing the hollow groove, and the side on which the fourth side of the box body piece is located is the same side as the side plate 4.3 with the shovel pressing plate on the bottom bracket 4;

[0043] Then the inner support frame on that side, on which the bottom film has been affixed, is pressed down (the bottom support plate moves downwards simultaneously). Due to the squeezing action of the two side plates of the bottom support plate, the box body piece stands up along the folds on both sides of the side surface at the bottom of the bottom support plate. Then both side plates are pressed inwards until the box body piece is completely formed and fitted onto the inner support frame. At the same time, the side plate with the shovel pressing plate on one side allows the edges of the fourth side surface and the first side surface of the box body piece on the outermost side to overlap together. Then the upper pressing frame on that side is pressed down until the box body is tightly attached to the inner support frame. At this time, the box body piece and the bottom film are also tightly bonded, completing the forming of the half-type packaging box body.

[0044] Then, the double-station rotary bracket rotates again, carrying the box body's inner support frame to the opposite side of the box body forming workbench. Then the two side plates and the upper pressing frame in the side pressure box assembly are returned to their original positions, and the suction cups at the ends of the box body's inner support frame are released, thereby releasing the box body. After that, the box body is removed from the box body's inner support frame through a manual or automatic unloading mechanism to complete the unloading of the box body.

[0045] After the completed box body on the box inner support frame on the double-station rotary bracket is unloaded, the box inner support frame of the side pressure box assembly circulates to complete the processes of pasting the box bottom film and the box body film.

[0046] The two groups of box pressing components on both sides of the double-station rotary bracket work simultaneously. When one group is forming the box body on one side, the other group is unloading the box body and pasting the box film on the other side, realizing the simultaneous production of two box bodies, fast production speed, improved equipment utilization, avoiding equipment waiting, and greatly improving production efficiency.

[0047] The various linear drive mechanisms used in the embodiments of the present invention are all commonly used linear drive structures in the prior art. The way in which the double-station rotary bracket realizes double-station rotation is also a commonly used way in the prior art, and will not be elaborated on here. For example, such a structure: the rotary bracket includes a workbench, a rotary mechanism and a drive mechanism; the workbench has two groups of press box assemblies, and the two groups of press box assemblies are symmetrically arranged on both sides of the workbench; the rotary mechanism includes a rotating spindle, bearings and rotating gears, and the bearings and rotating gears are both sleeved on the outside of the rotating spindle; the drive mechanism includes a telescopic mechanism and a transmission rack, the transmission rack is meshed with the rotating gear, the telescopic end of the telescopic mechanism is fixed to the transmission rack, and the telescopic length of the telescopic end is half of the circumference of the rotating gear; the workbench is fixedly connected to the rotating spindle.

[0048] The half-type packaging box body folding and forming device of the present invention has an ingenious structure. Through the cooperation of two sets of box pressing components on the double-station rotary bracket working at the same time, it can realize the simultaneous production of two half-type split box bodies. It can also be used to produce split box bodies of different heights for subsequent assembly into a complete packaging box. The production speed is fast, and the box body and the box bottom are combined and formed quickly and accurately. The equipment is streamlined, occupies a small area, and has low cost. It can adapt to the large-scale and rapid production of split packaging boxes, has strong practicality, and is worthy of promotion.

[0049] The present invention is not limited to the aforementioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
