Description

Technical Field

[0001] The utility model relates to the technical field of carton production, and particularly relates to a carton folding and packaging device. Background Technique

[0002] In modern logistics, warehousing and retail industries, cartons, as one of the main materials for commodity packaging, have huge and continuously growing demand. The traditional carton packaging process often relies on manual labor, which is not only inefficient but also costly. Especially when facing large-volume and high-speed production demands, manual packaging seems powerless. In addition, it is difficult to ensure the consistency and standardization of packaging by manual labor, increasing the risks of product damage and returns. To overcome the above problems, automated carton folding and packaging devices have emerged. Through various technical means such as machinery, electronics, pneumatics or hydraulics, these devices have realized the automated operation of a series of packaging processes for cartons from the flat state to forming, filling, sealing, etc.

[0003] Refer to the patent with the name of a carton folding and packaging device (publication number: CN220350104U), which includes a positioning base plate. Through an electric push rod, the pressing plate can be pushed downward to apply a downward pressure on the cardboard. Through a suction cup, the folded cardboard can be adsorbed. Subsequently, the rotation of the pressing plate带动 the cardboard to rotate, thereby changing the angle. Then, the cardboard is folded again. Through the coordinated use of a sleeve, a plug rod, a bearing plate and a telescopic spring, the pressing plate during the downward pressing process can be buffered. When the pressing plate is lifted, the bearing plate is reset through the telescopic spring. Through the coordinated use of a U-shaped mounting frame, a rotating rod, a folding plate, a fixed ring and a torsion spring, the function of folding the cardboard is achieved. When the pressing plate is lifted, the folding plate is reset through the torsion spring. Through the coordinated use of a bidirectional threaded rod, a first driving motor and a driving block, the distance between two U-shaped mounting frames can be adjusted, thereby folding the cardboard into cartons of different specifications.

[0004] Based on the above document, in the prior art, during the carton forming process of the device, when performing mechanical automated folding and pressing, for some folding cardboard with relatively thick thickness, the problem of uneven edge creases easily occurs,继而 affecting the accuracy of the finished packaging cartons. For this reason, the utility model provides a carton folding and packaging device. Content of the Utility Model

[0014] Beneficial effects

[0015] The utility model provides a carton folding packaging device. Compared with the existing technology, it has the following advantages:

[0016] (1) The carton folding and packaging equipment is designed with a rolling assembly. When the workpiece needs to be rolled, the telescopic cylinder is started to drive the extrusion mechanism to descend as a whole until the rolling wheel contacts the surface of the carton board. The motor is started and the gear transmission mechanism drives the threaded shaft on the same side to rotate. Since the threaded shaft and the threaded sleeve are threadedly connected and the upper limit of the frame is used, the threaded sleeve will move along its axial direction under the rotation of the threaded shaft. The rolling wheel is rotatably installed on the lower end of the threaded sleeve. Therefore, as the threaded sleeve moves, the rolling wheel will roll horizontally to roll the workpiece, thereby pre-pressing creases on the carton board, facilitating subsequent folding processing, and effectively avoiding the deviation of the carton folding packaging.

[0017] (2) The carton folding and packaging equipment is designed with a folding and pressing component. After the rolling prefabrication process is completed, the hydraulic cylinder is started, and the hydraulic rod at its end pushes the pressing block downward to formally fold and shape the workpiece. The pressure plate moves downward under the pressure of the workpiece, driving the elastic telescopic rod to compress. The design of the elastic telescopic rod provides the necessary downward pressing space and reset function for the folding process, ensuring the folding and forming of the carton board. As the pressure plate descends, the workpiece is gradually folded into the required shape between the pressure plate and the processing table. After the processing is completed, the elastic telescopic rod returns to its original shape, driving the pressure plate to rise and reset, ready for the next processing, and is easy to operate.
