Description

Technical Field

[0001] This utility model relates to the technical field of carton sealing equipment, and in particular to a carton sealing device and a fully automatic packaging system. Background Technology

[0002] Automated cardboard packaging refers to the process of packaging goods using cardboard using automated technology and equipment, and the resulting packaged products. It mainly includes: Cardboard conveying: automatically conveying stacks of raw cardboard to specific positions on the packaging equipment; Cardboard forming: folding, cutting, and die-cutting the cardboard according to a preset program and the dimensions of the goods to form boxes or cartons that can hold the goods; Item filling: accurately placing the items to be packaged into the pre-formed cardboard packaging using mechanical devices or robots; Sealing: sealing the cardboard containing the goods.

[0003] In the current carton sealing process, when switching between producing different sized cartons based on the item's dimensions, if the sealing dimensions are not easily adjustable, it may be impossible to find a suitable carton for packaging. Some items may have special packaging requirements, such as needing to add cushioning materials inside the carton or combining different packaging materials. Sealing systems with inflexible dimensions may not be able to meet these requirements because they cannot seal the carton according to the actual dimensions after adding materials. For example, when packaging fragile glass products, a large amount of foam or other cushioning materials needs to be placed inside the carton. If the sealing dimensions are fixed, the carton may be too tight, damaging the item, or the carton may not be completely sealed. Furthermore, inflexible sealing dimensions can disrupt the coordination between the sealing process and upstream and downstream processes such as carton forming and item filling. If the dimensions of the formed carton deviate slightly, and the sealing dimensions cannot be adjusted, it may lead to sealing difficulties, requiring manual intervention or rework.

[0004] Currently, no effective solutions have been proposed to address the problems of inconvenient box size adjustment and difficulty in sealing in related technologies. Utility Model Content

[0244] (a) First Baoding Process

[0245] The cardboard box enters the first conveying element 604 from the previous process, and the thirteenth drive element 606 is activated, causing it to drive the first conveying element 604 through the twenty-first transmission element 603. The first conveying element 604 drives the push element 605 to move accordingly, and the push element 605 performs the first conveying process of the cardboard box. During this process, the first drive element 121c is activated, causing it to drive the two first movable elements 121d to move towards each other in the horizontal direction through the cooperation of the first transmission element 121a and the second transmission element 121b. The two first movable elements 121d are driven by the cooperation of the corresponding seventh support element 121e and the eighth support element 122c. The two first holding elements 130 and the two first dispensing elements 140 move in a corresponding manner; the two second driving elements 122e are activated, so that they drive the corresponding second movable elements 122b to reciprocate in the vertical direction through the corresponding third transmission element 122d. The two second movable elements 122b drive the two first holding elements 130 and the two first dispensing elements 140 to move in a corresponding manner through the corresponding eighth support element 122c until the two first holding elements 130 and the two first dispensing elements 140 are adjusted to the designated position (so that the two first holding elements 130 are in contact with the fifth cardboard e), and then the first driving element 121c and the two second driving elements 122e stop working.

[0246] (ii) Second Baoding process

[0247] The third drive element 221e is activated, causing it to drive the third movable element 221b to move vertically downwards via the fourth transmission element 221d. The third movable element 221b then drives the two second fixing elements 230 to move accordingly via the ninth support element 221c until it contacts the third cardboard c, at which point the third drive element 221e stops operating. During this process, the fourth drive element 241b is activated, causing it to drive the two third fixing elements 250 to move horizontally away from the second fixing elements 230 via the tenth support element 241a, thereby assisting the two second fixing elements 230 in performing a second fixing process on the third cardboard c.

[0248] (III) First dispensing process

[0249] As the carton moves horizontally via the pushing element 605, the two first dispensing elements 140 operate, performing the first dispensing process on the fifth cardboard e, and finally the carton enters the second conveying element 704.

[0250] (iv) Restricting the movement of cardboard boxes

[0251] The fourteenth drive element 705 is activated, causing it to drive the second conveying element 704 via the twenty-second transmission element 703. The second conveying element 704 then performs a second conveying process on the carton. During this process, the two twentieth drive elements 922 are activated, causing them to drive the corresponding second limiting elements 930 vertically upward until the two second limiting elements 930 protrude from the second conveying element 704. Then, the two twentieth drive elements 922 stop operating. The nineteenth drive element 915 is activated, causing it to drive the eleventh movable element 913 horizontally via the twenty-eighth transmission element 914. The eleventh movable element 913 drives the two second limiting elements 930 to move accordingly via the twenty-fourth support element 921 until they are adjusted to the designated position. Then, the nineteenth drive element 915 stops operating.

[0266] (xii) Carton lifting process

[0267] The carton is conveyed to the two third conveying elements 1009 via the second conveying element 704. The sixteenth drive element 1010 is activated, causing it to drive the two twenty-fifth drive elements 1007 to rotate via the twenty-fourth transmission element 1006. The two twenty-fifth drive elements 1007 drive the third conveying element 1009 via the corresponding twenty-sixth transmission element 1008.

[0268] The advantages of this invention are as follows: the coordinated use of the first dispensing unit, the holding unit, the second dispensing unit, the first bending unit, and the second bending unit allows for corresponding adjustments to the dispensing, bending, and holding processes of the cartons, thereby meeting the sealing operations for cartons of different sizes and satisfying the packaging needs of different items. This avoids the problem of sealing difficulties caused by cartons not fitting the product. The coordinated use of the first and second limiting units allows for the limiting operations of cartons of different sizes, ensuring the reliability of the sealing process. The lifting unit lifts the cartons, facilitating the transport of the sealed cartons to the next process, thus improving the overall practicality of the device.
