[0019] 2. The structure of the bag separating mechanism is designed so that the first servo motor drives the first suction nozzle and the second suction nozzle to swing up and up, which can suck the bottom bag of the bag group from the bag storage mechanism. When the first servo motor drives the first suction nozzle and the second suction nozzle to swing down, the bottom bag of the bag group can be sucked and separated from the bag group, so that the bag group can be automatically separated and the bag separating efficiency is greatly improved.

[0020] 3. The structure of the bag feeding mechanism is designed so that the third servo motor drives the first bag opening component and the second bag opening component to move synchronously to the bag separating mechanism to suck the two outer walls of the bag opening of the packaging bag sucked and separated by the bag separating mechanism. The fourth servo motor drives the first bag opening component and the second bag opening component to separate, which can drive the two outer walls of the bag opening of the packaging bag to open outward to open the bag opening of the packaging bag. At the same time, the third servo motor drives the first bag opening component and the second bag opening component to move to the bagging station to put the packaging bag with the opened bag opening on the large item.

It has the advantages of high packaging efficiency, good packaging effect and low packaging cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In one embodiment, the working principle of the flexible packaging bag dispenser is as follows: when the handwheel 7 of the packaging bag storage mechanism 1 is rotated forward and reverse, the double-headed stud 6 can be driven to rotate forward and reverse synchronously to adjust the distance between the first distance adjusting plate 10 and the second distance adjusting plate 11, so that it can be suitable for stacking and preparing packaging bags of different widths. It sets the axial cross-section of the second roller 182 and the third roller 183 to a diamond structure and the middle part of the guide plate 16 to an arched structure. When the packaging bag group is placed on it, it can be arched by the second roller 182, the third roller 183 and the guide plate 16 to facilitate the bag-dispensing mechanism 2 to absorb the packaging bag at the bottom of the packaging bag group. The structural design of the packaging bag storage mechanism 1 makes it easy to absorb the packaging bags and ensures high efficiency in absorbing the packaging bags.

[0040] The first servo motor 24 of the bag-splitting mechanism 2 drives the flip plate 26 to swing back and forth via the first rotating shaft 23. The bag-feeding slide plate 202, the first suction nozzle mounting plate 204, and the second suction nozzle mounting plate 205 can swing along with the swinging of the flip plate 26. The first suction nozzle 206 and the second suction nozzle 207 can swing along with the swinging of the first suction nozzle mounting plate 204 and the second suction nozzle mounting plate 205. When the first suction nozzle 206 and the second suction nozzle 207 swing upward under the drive of the first servo motor 24, they can suck the bottommost bag in the bag group from the bag storage mechanism 1. When the first suction nozzle 206 and the second suction nozzle 207 swing downward under the drive of the first servo motor 24, they can suck the bottommost bag in the bag group and separate the bottommost bag from the bag group. This realizes the automatic separation of the bag group and greatly improves the bag separation efficiency of the bag group.

[0041] The third servo motor 35 of the bag feeding mechanism 3 drives the second belt transmission assembly 34 to drive the bearing frame 30 to move along the fourth linear sliding module 31, so that the first bag opening assembly 41 and the second bag opening assembly 42 are transferred to the bag dividing mechanism 2 together with the movement of the bearing frame 30. The first bag opening assembly 41 uses the third suction nozzle 417 and the fourth suction nozzle 418 and the second bag opening assembly 42 uses the fifth suction nozzle 427 and the sixth suction nozzle 428 to respectively suck the two outer walls of the packaging bag opening separated by the bag dividing mechanism 2. The fourth servo motor 38 drives the driving plate 301 to rotate through the third reducer 39 to drive the first bag opening assembly 41 and the second bag opening assembly 42 to separate, so that the two outer walls of the packaging bag opening can be opened outward as the first bag opening assembly 41 and the second bag opening assembly 42 are separated to complete the opening of the packaging bag. At the same time, the third servo motor 35 drives the first bag opening assembly 41 and the second bag opening assembly 42 to move to the bagging station to put the packaging bag with the opened bag opening onto the large items, thereby realizing automatic bagging of the large items.

[0042] The coordinated use of the packaging bag storage mechanism 1, the bag dividing mechanism 2 and the bag feeding mechanism 3 can realize the automatic extraction of a single packaging bag from the packaging bag group, the automatic opening of the packaging bag and the automatic packaging of large items, and the above series of operations do not require manual participation, so that it has the advantages of high packaging efficiency, good packaging effect and high degree of packaging automation for large items, and can reduce the labor intensity of workers, reduce the labor cost of enterprises and reduce packaging costs. It effectively solves the problems of low bagging efficiency, low degree of automation, high labor intensity of workers and high labor cost of bagging for enterprises due to the lack of automatic equipment for automatically opening the bag on the market.

Any technical solution that is identical or equivalent to the content described in the claims of the present invention should be included in the protection scope of the present invention.
