[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides the following technical solutions: A pneumatic auxiliary feeding device for a vertical packaging machine, including a horizontal cylinder 1, a conveyor 2 and a vertical packaging machine 3. One end of the horizontal cylinder 1 is provided with a connecting seat 4, and one end of the connecting seat 4 is connected with a vertical cylinder 5;

[0024] It should be noted that the horizontal cylinder 1 is used to drive the suction cup 13 to move horizontally, the conveyor 2 is used to convey articles, the vertical packaging machine 3 is used to package articles, and its model is: BZ-L. The vertical cylinder 5 is used to drive the suction cup 13 to move vertically, and the horizontal cylinder 1, the vertical cylinder 5, the conveyor 2 and the vertical packaging machine 3 are connected with an external power supply and a control switch;

[0026] It should be noted that the suction cup 13 is connected to an external vacuum pump through a pipeline, so as to realize the grasping of articles.

[0027] Preferably: One end of the bi-directional lead screw 9 is rotationally connected to the fixed frame 7 through a bearing, the ends of the two threaded connection blocks 10 are sleeved on the outer wall of the guide rod 11, four suction cups 13 are provided, and the four suction cups 13 are opposite to each other in pairs.

[0028] During specific use, the motor 8 drives the bidirectional lead screw 9 to rotate, causing the two threaded connection blocks 10 threadedly connected to its outer wall to move towards or away from each other along the guide rod 11. As the two threaded connection blocks 10 move, the two connection brackets 12 at the bottom will adjust the distance between the suction cups 13, thus facilitating the grasping of workpieces of different sizes.

[0029] It should be noted that when the motor 8 drives the bidirectional lead screw 9 to rotate clockwise, the two threaded connection blocks 10 will move towards each other. On the contrary, when the motor 8 drives the bidirectional lead screw 9 to rotate counterclockwise, the two threaded connection blocks 10 will move away from each other. The motor 8 is connected to an external power supply and a control switch.

[0030] Preferably: A base 19 is provided at the bottom of the horizontal cylinder 1. Two columns 14 are connected to the top of the base 19.

[0031] During specific use, by starting the two electric telescopic rods 17 to drive the connection block 18 to rise and fall, and since both ends of the connection block 18 are connected to the telescopic column 15, the telescopic column 15 will rise and fall along the slide groove 16 together, thus enabling the adjustment of the device height.

[0032] It should be noted that the two electric telescopic rods 17 are connected to an external power supply and a control switch.

[0033] Working principle: First, use the conveyor 2 to convey items. When it moves to the end, lower the suction cup 13 through the vertical cylinder 5, grasp the item with the suction cup 13 and rise. During this period, drive the bidirectional lead screw 9 to rotate by the motor 8, causing the two threaded connection blocks 10 threadedly connected to its outer wall to move towards or away from each other along the guide rod 11. As the two threaded connection blocks 10 move, the two connection brackets 12 at the bottom will adjust the distance between the suction cups 13, thus facilitating the grasping of workpieces of different sizes. And by starting the two electric telescopic rods 17 to drive the connection block 18 to rise and fall, and since both ends of the connection block 18 are connected to the telescopic column 15, the telescopic column 15 will rise and fall along the slide groove 16 together, thus enabling the adjustment of the device height. Then use the horizontal cylinder 1 to drive the grasped item to move horizontally until it reaches the vertical packaging machine 3.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
