Description

Technical Field

[0001] The utility model relates to the technical field of carton production, in particular to a flexible automatic sealing device for a carton. Background Art

[0002] A carton is a container made of cardboard, usually used for packaging goods and protecting items. The volume and shape of the carton vary according to the size and shape of the goods contained. Cartons are mainly made of cardboard, including corrugated cardboard, boxboard, etc. Cardboard is composited with multiple layers of paper, with three-layer, five-layer and seven-layer being common. The main function of the carton is to protect the items inside from damage and facilitate transportation, storage and display; carton sealing refers to the process of closing the opening part of the carton using specific adhesives or sealing equipment to ensure the safety, dustproof, moisture-proof and leakage prevention of the contents of the carton.

[0003] The patent document with application number CN202021123477.6 discloses an automatic carton sealing device, which includes a frame, a conveyor belt, a support frame, a motor and a tape mounting seat. The surface of the frame is connected to the conveyor belt, and the support frame is detachably connected to the top of the frame, and the motor and the tape mounting seat are respectively installed on the surface of the support frame. One end of the support frame is detachably connected to a cleaning mechanism through a card seat. The cleaning mechanism includes a circular tube, a partition, an air filter panel, an air blowing fan, a first air guide hood, an ion blower and a second air guide hood. The guide mechanisms are symmetrically installed on both side walls of the conveyor belt. The utility model has a novel design and a simple structure. A cleaning mechanism is detachably connected to one end of the support frame through a socket. The air blowing fan of the cleaning mechanism removes dust and cleans the open end of the carton, and the ion blower protects the open end of the carton from static electricity, thereby improving the firmness of the tape bonding. The carton is guided by the guide mechanism to improve the accuracy of bonding. Based on the search of the above patents and in combination with the carton sealing device in the prior art, it is found that when the existing carton sealing device is importing the carton, the cover of the carton is often in an unfolded state, and the staff needs to press it down in advance or use a pressure rod mechanism to press down the cover, which is time-consuming and labor-intensive. However, the carton sealing device needs to perform sealing operations on cartons of different specifications. The pressure rod mechanism of the existing carton sealing device has low adjustability and cannot adapt to cartons of various specifications. Utility Model Content

The carton body 4 passing through the pressing mechanism 5 will enter the gluing mechanism 6. The glue roll 603 in the gluing mechanism 6 is wound with adhesive tape, and the glue roll 602 is extended with adhesive tape. The adhesive tape is attached to the middle of the carton body 4 and then to the upper part of the carton body 4 to achieve the effect of sealing the cover of the carton body 4. If the overall position of the gluing mechanism 6 needs to be adjusted, it is only necessary to rotate the regulating screw 606 to drive the mounting bin 601, the gluing roller 602 and the glue roll 603 to adjust the height as a whole; in summary, the pressing mechanism 5 adopts a longitudinal and transverse displacement structure, which can be adjusted front and back and up and down, so that this mechanism is suitable for carton bodies 4 of various sizes, effectively improving the adaptability and practicality of the device, and then the cover of the carton body 4 can be effectively pressed down, which is convenient for subsequent gluing and sealing operations. The gluing mechanism 6 adopts an up and down adjustment structure, which can cooperate with the pressing mechanism 5 to adjust the height, so that the gluing mechanism 6 can effectively stick the tape on the carton body 4.
