The centering device 5 centers the inner and outer bags. The front trolley 23 is provided with a bag taking device 22 to send the bags to Filling station, the bag taking device 22 is provided with air claws 35 for grabbing the inner and outer bags, driven by an air cylinder, the filling station includes a telescopic tube 19, and an upper part of the telescopic tube 19 is provided The discharge gate 18 is provided with a buffer hopper 6 at the upper end of the discharge gate 18, and an automatic scale 8 is provided above the buffer hopper 6, and above the automatic scale 8 is a scale upper gate 9. 8 and the upper gate 9 on the scale weigh the raw materials of the specified weight and put them into the buffer hopper 6, and around the telescopic tube 19 is provided with a charging opening 20 that clamps the inner and outer bags of the double-layer bag and the double The inside and outside bags of the layered bag are gripped by the charging grab bag 21, the charging opening bag 20 and the charging grab bag 21 open the bag, the telescopic tube 19 extends into the double bag, and the discharge gate 18 is opened. Drop into the double-layer bag to realize automatic canning. After the canning is completed, it is clamped by the bag clamping device 17 on the small car 27 and sent to the twisting and binding station. The twisting and binding station includes a twisting device 15 and The opening device 13 is located on the right side of the twisting device 15. A twisting bag opening 14 and a twisting grabbing bag 16 are respectively arranged in the front and rear direction and the left and right direction of the twisting device 15. It is arranged in the front and rear direction and the left and right direction of the twisting device, that is, the twisting device is located in the middle, and the inner bag is twisted by the twisting device 15 first, and then the tying device 13 is used for tying. After finishing the twisting, the twisting The bag opening 14 and the twisting grab bag 16 open the outer bag, and the twisting device 15 will The bag is stuffed into the outer bag, and after completion, the bag is sent to the conveyor 29 by the bag holding device 12 of the linkage mechanism driven by the cylinder on the rear trolley 28, and the conveyor 29 sends the bag into the seam. The seaming station includes a bag mouth shaping 11 for shaping the mouth of the bag. A sewing machine 10 for sewing the outer bag is provided at the right end of the bag mouth shaping 11, and the sewing bag passes through the conveyor 29 output, complete the complete set of actions such as automatic bag loading, inner bag sorting, bag centering, firm filling and twisting and binding. It is an automatic packaging machine. The small and medium-sized car 27 is provided with a double-layer bag A solid mechanism 26 for carrying out raw materials. The solid mechanism 26 is driven by an air cylinder or a cylinder and a connecting rod mechanism. The double-layer bag is stiffened by the air cylinder or a cylinder and a connecting rod mechanism. The bag clamping device on the small and medium car An exhaust device 24 for venting the bag and an air blowing device 25 for arranging the bag are provided on 17. The exhaust device 24 is composed of an exhaust plate or an exhaust plate driven by compressed air plus a flexible inflation device. The blowing device 25 is composed of a blower tube driven by compressed air or a fan. A cleaning device 7 is provided above the buffer bucket 6, and the cleaning device 7 is a nozzle for cleaning the buffer bucket 6 that sprays compressed air. , The preferred number of nozzles is three, and the compressed air sprayed from multiple nozzles cleans the packaged particles in the buffer hopper.

[0036] A packaging method for a fully automatic double bag packaging machine, the packaging method includes the following steps:

[0037] (1) Bag loading: manually place one or more double-layer bags on the bag platform 1;

[0038] (2) Sorting and centering: The bag separating device 2 removes the single double-layer bag and sends it to the inner bag sorting device 3. The bag is smoothed by the inner bag sorting 3, and the bag is sent to the inner bag sorting device 4 after being smoothed. The centering device 5, the centering device 5 centers the inner and outer bags;

[0039] (3) Filling and solid: the bag taking device 22 on the front trolley 23 sends the bag to the filling station. Grasp the inside and outside of the bag firmly, then the front trolley 23 returns to load and open the bag 20, and the charging grab 21 punches the bag for filling. At this time, the automatic scale 8, the upper gate 9 of the scale will weigh the raw materials of the specified weight And put it into the buffer bucket 6, the telescopic tube 19 stretches into the double bag and opens, the discharge gate 18 opens the discharge to realize automatic filling, while filling, the solid mechanism 26 on the medium and small cart 27 solidifies the raw materials;

[0040] (4) Tie the mouth: After filling, the bag clamping device 17 on the small car 27 clamps the bag and sends it to the tying station. The exhaust device 24 on the bag clamping device 17 exhausts the bag while blowing air. The device 25 sorts the bag; after the bag is sent to the tying station, the inner and outer bags are clamped and grasped by the twisting opening 14 and the twisting grabbing bag 16 respectively. The twisting device 15 first twists the inner bag, and then The tying device 13 performs the tying. After the tying is completed, the outer bag is opened by twisting the bag 14 and twisting the grabbing bag 16, and the inner bag is stuffed into the outer bag by the twisting device 15, and the bag holding device 12 on the rear trolley 28 The bag is sent to the conveyor 29, and the bag mouth shaping 11 reshapes the mouth of the bag. After that, the sewing machine 10 sews the outer bag. After completion, the conveyor 29 outputs the bag.
