[0034] The working principle of the bag opening platform 100 of the present application will be described in detail in combination with the drawings.
[0035] Firstly, the packaging bag 200 to be opened is placed in the bag opening area 40, the first suction cup 22 adsorbs and fixes the front end of the lower surface of the packaging bag 200, and the second suction cup 23 adsorbs and fixes the middle rear end area of the lower surface of the packaging bag 200.
[0036] Then, the first lifting driving mechanism 31 drives the first lifting mounting seat 32 to move the third suction cup 33 vertically downward to the front end of the upper surface of the packaging bag 200, and then the third suction cup 33 adsorbs the front end of the upper surface of the packaging bag 200. Then, the first lifting driving mechanism 31 drives the first lifting mounting seat 32 to move the third suction cup 33 vertically upward, that is, the third suction cup 33 drives the front end of the upper surface of the packaging bag 200 to move upward, thereby preliminarily opening the bag opening 201 of the packaging bag 200.

At the same time, the third opening claw 58 and the fourth opening claw 59 are driven to move apart from each other in the left-right direction by the second opening and closing driving mechanism 55, the third opening claw 58 is driven downward by the fourth lifting driving mechanism 56b through the fourth lifting mounting base 56a, and the fourth opening claw 59 is driven to move vertically up and down by the fifth lifting driving mechanism 57b through the fifth lifting mounting base 57a. So that the first opening claw 65 and the second opening claw 66 can be opened in the left-right direction while moving upward synchronously, and the third opening claw 58 and the fourth opening claw 59 can be opened in the left-right direction while moving downward synchronously, so as to ensure that the opened bag opening 201 is in a state of opening and tensioning.
[0040] Finally, the first connecting arm 73 drives the second connecting arm 74 to drive the rotating connecting base 75 to drive the rotating pressing plate 76 to press on the part of the bag opening 201 of the packaging bag 200 between the third opening claw 58 and the fourth opening claw 59, so as to press the part of the bag opening 201 of the packaging bag 200 between the third opening claw 58 and the fourth opening claw 59 on the front end of the bearing plate 21, thereby completing the opening operation of the bag opening 201 of the packaging bag 200, that is, the product can be loaded into the packaging bag 200 from the opened bag opening 201.
