[0002] Packaging machines are very common in modern industrial production processes. The packaging machines used for packaging different products are also different. Bag-feeding packaging is one of them. Bag-feeding packaging machines require the cooperation of multiple mechanisms during use. The bag feeding mechanism is one of them. Its main function is to continuously transport the packaging bags to the bottom of the bag feeding mechanism. The bag feeding mechanism continuously picks up the packaging bags at the predetermined position of the bag feeding mechanism, thereby cooperating to complete the packaging bag supply task.

[0003] The position of the suction nozzle of the bag feeding device of the existing bag-feeding packaging machine is usually fixed and cannot be adjusted according to the specifications of the empty packaging bag. In addition, when the packaging bag has static electricity, two or more bags will be adsorbed at the same time, and the bag cannot be fed normally individually. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] Example 1

[0020] See also Figure 1-3 The bag feeding device of the bag feeding type packaging machine comprises a mounting plate 1, on which a pipe sleeve 2 is rotatably arranged through a rotating shaft, in which a movable rod 3 is movably arranged, and a support member 4 is fixedly arranged at the bottom end of the movable rod 3. A driving component for driving the support member 4 to flip at a right angle is also provided on the mounting plate 1. A pair of transverse plates 5 are symmetrically arranged on the support member 4, and a plurality of suction nozzles 6 are evenly spaced on the transverse plates 5. The support member 4 is provided with strip holes 7 for the suction nozzles 6 to slide, and the support member 4 is also provided with an adjusting component for adjusting the spacing between the two transverse plates 5. By setting the transverse plate 5, the strip holes 7 and the adjusting component, the adjusting component can make the suction nozzles 6 on the two transverse plates 5 relatively close to or far away from each other when adjusting the spacing between the two transverse plates 5, so as to realize the adjustment of the position of the suction nozzle 6. The adjusted suction nozzle 6 can be suitable for feeding empty packaging bags of different specifications, and has the advantage of wider practicality.

[0021] Among them, the adjustment component includes an outer shell 8, a rotating member 9, a first connecting rod 10 and a push-pull rod 11. The outer shell 8 is fixedly mounted on the support member 4, and the bottom end of the movable rod 3 is fixedly mounted on the top surface of the outer shell 8. The rotating member 9 is rotatably arranged in the outer shell 8 and is driven by a servo motor arranged in the cover shell. Push-pull rods 11 are symmetrically and movably inserted on both sides of the outer shell 8. One end of the push-pull rod 11 is fixedly connected to the cross plate 5, and the other end is connected to the rotating member 9 through the first connecting rod 10, wherein the two ends of the first connecting rod 10 are respectively hinged to the push-pull rod 11 and the rotating member 9. Specifically, when the motor drives the rotating member 9 to rotate, under the action of the two first connecting rods 10, the two push-pull rods 11 are synchronously extended and retracted on the side wall of the outer shell 8, thereby promoting the relative movement of the two cross plates 5 and realizing the adjustment of the position of the suction nozzle 6.

[0022] Among them, the driving assembly includes a mounting shaft 13, a flip rod 14, a fixed plate 15 and a power unit. The mounting shaft 13 is rotatably mounted on the mounting plate 1, and the flip rod 14 is fixedly mounted on one end of the mounting shaft 13. The fixed plate 15 is fixedly mounted on the support member 4, and a boss 16 is rotatably mounted on the fixing plate 15. The boss 16 is fixedly mounted on the side of the flip rod 14. The power unit is used to provide power for the reciprocating rotation of the mounting shaft 13.

[0023] Specifically, the power unit includes a rotating rod 17, a second connecting rod 18, a driving rod 19 and a stepper motor 20. The rotating rod 17 is fixedly mounted on the other end of the mounting shaft 13, the stepper motor 20 is fixedly mounted on the side of the mounting plate 1, and the output end of the stepper motor 20 is fixedly mounted with the driving rod 19, the driving rod 19 is connected to the rotating rod 17 through the second connecting rod 18, wherein the two ends of the second connecting rod 18 are hinged to the driving rod 19 and the rotating rod 17 respectively. Specifically, in the process of driving the driving rod 19 to rotate, the stepper motor 20 can drive the rotating rod 17 to connect with the mounting shaft 13 to reciprocate within a certain angle range under the action of the second connecting rod 18. During this process, the flipping rod 14 rotates reciprocatingly therewith. When the flipping rod 14 flips toward the direction of the support member 4, it can drive the support member 4 to connect with the movable rod 3 to move downward to achieve the adsorption of the empty packaging bag. Conversely, when the flipping rod 14 flips in the opposite direction, the support member 4 first moves upward and then turns 90° to deliver the bag.

[0024] Example 2

[0025] This embodiment is improved on the basis of embodiment 1, specifically:

[0026] See also Figure 2 A pair of vibrators 12 are also fixedly arranged on the support member 4. The vibrators 12 are arranged so that after the suction nozzle 6 adsorbs the empty packaging bag, the two vibrators 12 can drive the support member 4 to vibrate at a high frequency, so as to separate the empty packaging bags adsorbed together by electrostatic force, thereby ensuring that the device can stably deliver a single bag.
