[0020] The following further describes the full-automatic box folding mechanism of the present invention in detail in conjunction with the drawings and specific embodiments.

[0021] As shown in the figure, the full-automatic box folding mechanism of the present invention includes a blank placing rack 2 for placing box blanks 1, a blank picking device 5 having a blank picking suction cup turning device 3 and a blank picking suction cup lifting device 4, a box folding lifting device 6 for collecting box blanks from the blank picking suction cup lifting device, and a side box widening device 7, a left box folding device 8, a right box folding device 9, a top box tongue device 10 and a box inserting flap device 11 for successively widening, folding and inserting the box blanks collected on the box folding lifting device. There is an inclined angle between the blank placing rack 2 and the horizontal plane. The blank picking suction cup lifting device 4 is arranged at the open end on the lower side of the blank placing rack. Figure 3It can be seen that the loading rack 2 is inclined from the upper right side to the lower left side. The material taking suction cup lifting device 4 is arranged at the open end on the lower left side of the loading rack. The said material taking suction cup lifting device 4 includes a material taking rack 13, a material taking lifting cylinder 14 arranged on the material taking rack, and a material taking vacuum suction cup 15 installed on the material taking lifting cylinder. The material taking suction cup flipping device 3 is a material taking suction cup flipping cylinder 16. The fixed end of the material taking suction cup flipping cylinder 16 is hinged on the vertically arranged lower rack, and the telescopic end of the material taking suction cup flipping cylinder 16 is hinged on the material taking rack, and the material taking rack is hinged on the vertically arranged upper rack. By the extension of the telescopic end of the material taking suction cup flipping cylinder, the material taking vacuum suction cup 15 is made to face the loading rack. At the same time, by the action of the material taking lifting cylinder, it approaches the loading rack and then uses the material taking vacuum suction cup 15 to take materials. At the same time, it can also contract the telescopic end of the material taking suction cup flipping cylinder to send the box blank to the box folding lifting device after taking materials. Thus, through the cooperation of the material taking suction cup flipping device and the material taking suction cup lifting device, the purpose of taking materials from the loading rack and sending the obtained box blank to the box folding lifting device 6 is achieved; the box folding lifting device 6 includes a box folding lifting cylinder 17 and a box folding vacuum suction cup 18 arranged at the telescopic end of the box folding lifting cylinder. By the telescopic movement of the box folding lifting cylinder 17, the box folding vacuum suction cup can suck the box blank on the flipped material taking vacuum suction cup; the side box widening device 7 is arranged beside the box folding lifting device 6. The side box widening device 7 includes a side box widening cylinder 19 and a side plate 20 hinged on the telescopic end of the side box widening cylinder. By the telescopic movement of the side box widening cylinder 19, the side plate can be erected to press and fold the box blank received on the box folding lifting device, achieving the purpose of widening the box. The left box folding device 8 and the right box folding device 9 are respectively box folding cylinders capable of bending the left box tongue or the right box tongue. The left box folding device 8 is arranged at the left box tongue of the box blank, and the right box folding device 9 is arranged at the right box tongue of the box blank. Thus, the left box tongue of the box blank after widening the box can be bent by the left box folding device 8, and the right box tongue of the box blank after widening the box can be bent by the right box folding device 9. The top box tongue device 10 is arranged at the bottom box tongue of the box blank and can bend the bottom box tongue.

The top box tongue slider can bend the bottom box tongue through the telescopic movement of the top box tongue cylinder; the said insert box flap device 11 includes a folding box track plate cylinder 23 and a folding box track plate 24 connected to the telescopic end of the folding box track plate cylinder. It also includes an insert box flap 25 and an insert box flap 26 connected to the telescopic end of the insert box flap. The insert box flap inserts the box tongue into the box body through the cooperation of the folding box track plate on the folding box track plate cylinder 23 and the insert box flap on the insert box flap cylinder 25.

[0024] Its working principle is as follows:

[0025] Place the box blanks on the feeding rack in sequence. The picking suction cup flipping cylinder extends to make the picking rack flip upward. The picking suction cup lifting cylinder extends. After the picking vacuum suction cup is attached to the box blank, the vacuum is turned on. The picking suction cup lifting cylinder retracts, and the picking suction cup flipping cylinder retracts to make the picking rack flip downward;

[0026] The folding box lifting cylinder extends. The folding box vacuum suction cup is attached to the picking vacuum suction cup and the box blank after flipping. The folding box vacuum suction cup turns on to suck vacuum. The folding box lifting cylinder retracts. The picking suction cup vacuum is turned off, and the picking suction cup flipping cylinder extends to make the picking rack flip upward;

[0027] The side box widening cylinder extends, and the side box widening side plate stands up to make the box in the folding box step 1;

[0028] After the front left folding box cylinder and the right folding box cylinder extend, they pause and retract as in folding box step 2. The front top box tongue cylinder extends, and the front top box tongue slider bends the front box tongue. The front top box tongue cylinder retracts;

[0029] The folding box track plate cylinder extends, and the insert box flap cylinder extends to make the insert box flap insert the box tongue into the box body;

[0030] The folding box track plate cylinder and the insert box flap cylinder retract to complete the folding of the box;

[0031] Finally, the formed box is blown out by the discharging blowing device, and the above actions are repeated to form a full-automatic folding of the box.

[0032] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
