[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0022] The following detailed description of the specific embodiments of this utility model, in conjunction with the accompanying drawings, illustrates the following: A packaging bag assembly for holding continuous packaging bags includes a support 21, a lower cover 22, a packaging bag roll 28, and a support ring 8. The support 21 has a "┳" shaped structure, with a through hole A23 opening at the center and multiple through holes B evenly distributed on the upper surface of the support 21. The lower end of the support 21 has a lower cover 22, which is a ring. The inner diameter of the lower cover 22 is larger than [missing information - likely a diameter value]. The lower outer diameter of the bracket 21 and the end face of the lower cover 22 are evenly distributed with multiple through holes C, which are adapted to through holes B. A bolt 24 is inserted between through holes B and through holes C. The bolt 24 passes through the bracket 21 and the lower cover 22, and the lower end of the bolt 24 protrudes from the lower cover 22. A nut A25 is provided at the protruding end of the bolt 24 for fixing the lower cover 22. A nut B26 is provided on the inner side of the bolt 24 and the lower cover 22 for adjusting the distance between the inner sides of the bracket 21 and the lower cover 22. The distance is such that the lower cover 22 cannot move up and down. In actual use, in order to avoid the packaging bag 27 inside the packaging bag assembly from being contaminated by the external environment, such as dust pollution in the production workshop, a dust cover can be wrapped around the bolt 24 to avoid external pollution without affecting the use. The packaging bag roll 28 is sleeved on the outside of the middle column of the support 21. The packaging bag roll 28 is made of soft material and is formed by folding multiple consecutive packaging bags 27 with openings at the top and bottom. The inner diameter of the packaging bag 27 is larger than the outer diameter of the column of the support 21 so that the packaging bags 27 can be folded together. While saving space, more packaging bags 27 can be placed. The starting end of the packaging bag roll 28 passes through the gap between the lower cover 22 and the support 21. In the process of making the packaging bag assembly, multiple consecutive packaging bags 27 are first sleeved on the central column of the support 21 to form the packaging bag roll 28, and then the lower cover 22 is placed on the packaging bag roll 28 and fixed by bolts.
[0023] During transportation, the lower cover 22 has multiple protective plates 29 on its lower end face. The protective plates 29 have mounting holes at both ends and are mounted on bolts 24 through the mounting holes. Since the lower cover 22 and the bracket 21 are only connected by a few bolts, they are easily damaged during transportation. Therefore, when transporting the packaging bag assembly, the protective plates 29 are installed on the lower end face of the lower cover 22 to effectively prevent damage to the packaging bag assembly during transportation.
[0024] When the packaging bag assembly is in use, a support ring 8 is provided on the lower end face of the lower cover 22. The support ring 8 includes an outer ring 81 and an inner ring 83, which are connected by a connecting rod. A fixing seat 82 is provided at the upper end of the inner ring 83, and the fixing seat 82 is installed on the lower end face of the lower cover 22 by screws. The outer ring 81 is adapted to the inner diameter of the packaging bag 27. In order to facilitate the removal of the packaging bag 27, the outlet diameter at the lower end of the lower cover 22 is smaller than the diameter of the packaging bag 27, which is prone to wrinkles. The support ring 8 can support the packaging bag 27, which can effectively reduce wrinkles and facilitate the use of the packaging bag 27.
[0025] The usage process of this utility model is as follows: When making the packaging bag assembly, first, the bracket 21 is inverted on the bagging device, and then the packaging bag 27 is placed on the outside of the middle column of the bracket 21 and folded to form a packaging bag roll 28; then, the lower cover 22 is placed on the upper end of the packaging bag roll 28, and the starting end of the packaging bag roll 28 is passed through the gap between the lower cover 22 and the bracket 21, and then the lower cover 22 and the bracket 21 are connected together using bolts 24. During connection, the distance between the inner sides of the bracket 21 and the lower cover 22 can be adjusted using nuts B26; when the packaging bag assembly needs to be transported, a protective plate 29 can be installed on the lower end face of the lower cover 22 for transportation; when the packaging bag assembly is in use, a support ring 8 can be installed on the lower end face of the lower cover 22, and then the packaging bag assembly is placed on the conveying pipe of the dustproof automatic feeding bagging device, and the lower end face of the packaging bag assembly is fixed using the support rod of the bracket; when filling corundum powder, the packaging bag 27 in the packaging bag assembly 2 passes through the gap between the lower cover 22 and the bracket 21. The packaging bag 27 passes through the gap between the supports 21; the packaging bag 27 first passes through the conveyor belt 7; at this time, the lower end of the packaging bag 27 is located at the sealing and cutting device 4, and the conveyor belt 7 moves the packaging bag 27 downward to a certain length; after the packaging bag 27 has moved, the corundum powder flows out from the outlet of the weighing hopper 3 and enters the packaging bag 27 through the conveying pipe 1; then, the conveyor belt 7 moves to clamp the packaging bag 27; after the sealing and cutting device 4 clamps the packaging bag 27, the heating plate of the sealing and cutting device 4 is activated, the heating plate seals the packaging bag 27, and then the cutter of the sealing and cutting device 4 cuts the packaging bag 27; after the packaging bag 27 is cut, it is placed on the conveyor belt 5 and enters the next process with the movement of the conveyor belt 5; finally, the conveyor belt 7 moves the packaging bag 27 downward to a certain length again and continues the next filling; when the packaging bag 27 of the packaging bag assembly is used up, the used packaging bag assembly is removed, a new packaging bag assembly is replaced, and the production operation continues.
