Description

Technical Field

[0001] The invention belongs to the field of packaging box production, and in particular relates to a full-automatic half-type packaging box body folding and forming system. Background Art

[0002] As people's living standards improve, they have higher and higher requirements for all aspects of goods. Nowadays, there are a wide variety of goods, and the first thing that catches the eye is often the outer packaging of the product. A good outer packaging can be a great boost to sales. Especially for some high-end products, the outer packaging of the product is more important to the sales of the product, especially it can attract consumers, increase the added value of the product, meet the spiritual needs of consumers, and consolidate the brand and corporate image.

[0003] Traditional packaging boxes are usually one-piece molding structures, which leads to serious material waste and high material costs. In order to reduce material costs, more and more sliced ​​combination packaging boxes are used in production. Even many wine manufacturers like Jiannanchun still prefer upper and lower split combination packaging boxes, that is, the entire box body is composed of two half-section packaging box bodies spliced ​​together. The two half-section packaging box bodies required for the existing upper and lower split combination packaging boxes are either made by manual bonding or by machinery. The manual bonding production is time-consuming and labor-intensive, with low production efficiency, low precision, and high labor costs. The existing upper and lower split combination packaging box manufacturing machinery is either more complex, with high equipment costs and a large footprint, or can only be semi-automated for production, with low production efficiency and unable to meet the requirements of large-scale rapid production. For this reason, people hope to have better equipment with higher production speed, higher equipment cost performance and smaller footprint to complete these tasks. Summary of the invention

[0029] The rotating bracket carries the box pressing assembly, and on the side where the box body forming workbench is located, can complete the covering of the upper box body piece on the four side surfaces of the inner box support frame of the box pressing assembly. 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.

[0030] The specific working process is as follows: On the side where the bottom-attaching and unloading workbench is located, the inner box support frame of the box pressing assembly on the rotating bracket rises to the position when the box bottom film flipping mechanism is flipped up 90 degrees, and then the box bottom film segmentation feeding mechanism supplies a piece of box bottom film material to the supporting table of the box bottom film flipping mechanism, and then the box bottom film flipping mechanism is flipped up 90 degrees to attach the box bottom film to the bottom of the inner box support frame, and then the rotating bracket rotates to the side where the box body forming workbench is located.

[0031] On the side where the box body forming workbench is located, the bottom support plate on the bottom bracket of the box pressing assembly on the rotary bracket rises to a position flush with the hollow groove, and then a box body piece with four sides that are pre-folded between two adjacent sides is placed on the hollow groove on the box body forming workbench by the box body piece grabbing robot, ensuring that the second side of the box body piece is facing the hollow groove, and the side where 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, and then the box inner support on this side with the box bottom piece attached The support frame is pressed down (the bottom support plate is moved down synchronously), and due to the squeezing effect 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 located at the bottom of the bottom support plate, and then the two side plates are pressed inward until the box body piece is completely formed and attached to the support frame inside the box, and at the same time, through the effect of the side plate with the shovel plate on one side, the edges of the fourth side surface and the first side surface of the box body piece at the outermost side can be overlapped together; then the upper pressing frame on this side is pressed down until the box body is tightly attached to the support frame inside the box, and at this time, the box body piece and the box bottom piece are also tightly bonded; Then, the swivel bracket rotates again, carrying the box inner support frame of the completed box body to the bottom unloading workbench, and then the two side panels and the upper press frame are returned to their original positions, and the suction cups at the ends of the box inner support frame are released, thereby releasing the box body. Thereafter, the material shifting block under the bottom unloading workbench acts on the top of the box body to push the box body mounted on the box inner support frame backwards, and at the same time, the unloading suction block located at the rear end cooperates to suck the bottom plate of the box body from the rear side to pull the box body backwards until the box body is completely pulled out and disengaged from the box inner support frame, thus completing the unloading of the box body, and the unloaded box body is transported to the next process via the box body output conveyor belt.

[0032] After the finished box body on the box inner support frame on the rotary bracket is unloaded, the side box inner support frame rises upward until it rises to the position where the box bottom film flipping mechanism flips upward 90 degrees, and the process of pasting the box bottom film and the box body film is completed in a cycle.

[0033] Two groups of box pressing components on both sides of the rotating bracket work simultaneously. One group is on the box body forming workbench to form the box body, and the other group is on the bottom unloading workbench to unload the box body and stick the box film. This realizes the simultaneous production of two box bodies, fast production speed, improved equipment utilization, avoided equipment waiting, and greatly improved production efficiency.

[0034] The fully automatic half-section packaging box body folding and forming system of the present invention has an ingenious structure. Through the cooperation of two sets of box pressing components and two workbenches on a rotating bracket, it can realize the simultaneous production of two half-section 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 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.

[0035] The present invention is not limited to the above-mentioned 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.
