A side block connecting plate 515 and a side block 501 are also provided at the top of the side block bracket 514.

[0050] The working principle and working process of the present invention are as follows:

[0051] The positioning knob of the bagging device 2 is used to adjust the relative position of the movable support frame 203 and the bracket 209, so as to adjust the distance between the movable support frame 203 and the fixed support frame 205 to adapt to bag openings of different sizes.

[0052] According to the size of the bag opening, after determining the scale along the ruler, first fix the fixed support frame 205, then put one side of the bag opening on the movable support frame 203, and manually pull the other side of the bag opening to make the movable support frame 203 move to the right along the guide shaft 204 until the other side of the bag opening is put on the fixed support frame 205. After releasing your hand, the movable support frame 203 moves to the left along the guide shaft 204 under the action of the spring connecting rod 201 until the bag opening is opened by the movable support frame 203 and the fixed support frame 205.

[0053] After the bag opening is opened, the bag transfer cylinder 402 of the upper bag transfer trolley 4 extends, pushes the swing arm cylinder seat 416 through the connecting bent plate 420, pushes the swing arm cylinder 417 and the swing arm 418 to the position of the bagging device 2, the swing arm cylinder seat 416 shrinks, the swing arm turns downward, and the bag support plate 419 extends into the packaging bag with the bag opening jointly opened by the movable support frame 203 and the fixed support frame 205, and the packaging bag is removed;

[0054] Subsequently, the bag transfer cylinder 402 contracts, driving the swing arm 418 to move to the left, and moving the packaging bag taken by the swing arm 418 to the discharge port at the lower end of the material port 313 on the clamping bag support device 3, and the swing arm cylinder seat 416 extends, and the swing arm 418 rotates upward, driving the bag opening to move upward and be sleeved at the discharge port.

[0055] Subsequently, the connecting rod cylinder 314 on the clamping bag-holding device 3 extends downward, driving the bent rod 308 to rotate outward, pushing the support rod 309 to hold the bag mouth open in the left and right directions; the clamping cylinder 306 opens, pulling the material mouth baffle to open, and holding the bag mouth open in the front and back directions. The material mouth baffle and the material mouth 313 clamp the bag mouth together, completing the clamping bag-holding, i.e., bag loading process.

[0056] Subsequently, the material opening 313 discharges the material into the packaging bag. After the material discharge is completed, the clamping cylinder 404 of the upper bag transfer trolley 4 drives the clamping bent plate 403 to clamp the bag opening of the upper packaging bag that has been loaded. The bag holding cylinder 406 drives the bag holding plate 405 to clamp the packaging bag. The upper bag transfer trolley 4 transports the packaging bag to the next process, that is, after the packaging bag discharge process is completed, it is transported to the next process. The clamping bent plate 403, the clamping cylinder 404, the bag holding plate 405, and the bag holding cylinder 406 are all two groups, symmetrically arranged on the trolley bracket 407 and the front and rear sides of the conveyor 1 to prevent the packaging bag from tipping over during transportation.

[0057] Therefore, the bag loading and transferring trolley 4 can realize the synchronous shifting of the last full packaging bag while the swing arm 418 takes and loads the bags, thus completing the action process of switching the workstation of the bag loading and transferring trolley 4.

[0058] The conveyor lifting and width adjustment device 5, when the full packaging bags delivered by the bag transfer trolley 4 and the conveyor belt 502 are conveyed to the subsequent workstation under the limit of the side block 501; when the packaging bags are of different sizes, it is necessary to drive the conveyor frame 506 and the conveyor belt 502, etc. under the action of the lifting cylinder 519, which is controlled by the lifting roller group 516 and the lateral positioning roller 520, and slowly moves up and down along the lifting shaft 517 to reach the appropriate position of the position scale, and manually press the pin 509 into the corresponding hole of the position scale 508 to complete the height positioning of the conveyor belt 502;

[0059] When it is necessary to adjust the width of the side block 501, that is, to adjust the distance in the width direction of the side block 501 according to the thickness of the packaging bag conveyed on the conveyor belt 502, the hand-cranked rotating disk 512 drives the parallel connecting rod 511, the linkage assembly 510, the side block bracket 514, the side block connecting plate 515 and the side plate 501 to complete the positioning in the width direction, and the nut on the movable plate 513 is locked at the current width position to complete the adjustment of the width direction of the conveyor.

[0060] The above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms. Any technician familiar with the profession may use the above disclosed technical content to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention without departing from the technical solution of the present invention still belongs to the protection scope of the technical solution of the present invention.
