[0018] As Figures 1 to 3 shown, the utility model discloses a stable bagging device for a granular packaging machine, which includes a material bin 1. An outlet channel 2 is provided on the material bin 1. The height of the outlet channel 2 decreases successively along the direction away from the material bin 1 and forms an inclined outlet side wall. Bag pressing openings 21 and a bag pressing mechanism 3 are provided on both sides of the outlet channel 2. The bag pressing mechanism 3 is used to press the packaging bag sleeved at the bottom end of the outlet channel 2 into the bag pressing openings 21 to fix the packaging bag. A support plate 4 is provided below the outlet channel 2. The support plate 4 is used to support the packaging bag. After the packaging bag is sleeved on the port of the outlet channel 2, part of the packaging bag is pressed into the bag pressing openings 21 by the bag pressing mechanism 3 to fix the packaging bag. In this way, the hands of workers can be liberated and the working intensity of workers can be reduced. Since the bag pressing openings 21 are recessed downward, after part of the packaging bag is pressed into the bag pressing openings 21, the packaging bag can be stably fixed. And by pressing to fix the packaging bag, damage to the bag mouth of the packaging bag can be prevented, so that the breakage of the bag mouth of the packaging bag can be avoided and the subsequent sealing quality of the packaging bag can be affected.

[0019] In this embodiment, the specific structure of the bag pressing mechanism 3 includes a cylinder 31 and a pressing plate 32. The pressing plate 32 is located at one end facing the bag pressing opening 21 as the pressing end. One side of the output end of the cylinder 31 is provided with a connecting rod 33. A first rocker 34 is provided between the connecting rod 33 and the pressing plate 32. One end of the first rocker 34 is rotatably connected to the connecting rod 33, and the other end is rotatably connected to the pressing plate 32. An outwardly extending connecting flange 35 is provided on the output end of the cylinder 31. A second rocker 36 is provided between the connecting flange 35 and the pressing plate 32. One end of the second rocker 36 is rotatably connected to the connecting flange 35, and the other end is rotatably connected to the pressing plate 32. A driving rod 37 is provided between the output end of the cylinder 31 and the first rocker 34. One end of the driving rod 37 is rotatably connected to the first rocker 34, and the other end is rotatably connected to the output end of the cylinder 31. After the worker sets the packaging bag on the port of the discharge channel 2, by extending the output end of the cylinder 31, the second rocker 36 can be driven to rotate towards the bag pressing opening 21, and the first rocker 34 can also be driven to rotate towards the bag pressing opening 21 under the push of the driving rod 37. In this way, the pressing end can be driven to press into the bag pressing opening 21 to fix the packaging bag. Similarly, after the packaging bag is filled with granular materials, by retracting the output end of the cylinder 31, the pressing end can be driven to move away from the bag pressing opening 21 to release the packaging bag. At this time, the packaging bag can be taken off. In this way, only by the telescopic movement of the output end of the cylinder 31, the fixing and releasing of the packaging bag can be realized, which is convenient for operation and use.

[0020] In this embodiment, the support plate 4 includes a base portion 41 and a moving portion 42. A spring 5 is provided between the base portion 41 and the moving portion 42. There are multiple springs 5 and they are arranged at intervals. One end of the spring 5 is fixed to the base portion 41, and the other end is fixed to the moving portion 42. When filling the granular materials into the packaging bag, the spring 5 provided can buffer the packaging bag to prevent the gravity generated due to the too fast filling speed of the granular materials from tearing the packaging bag.

[0021] In this embodiment, guide plates 6 are further fixed on both sides of the base portion 41. First guiding flanges 421 protruding from both sides of the moving portion 42 are provided. First guiding grooves 61 corresponding to the first guiding flanges 421 are provided on the inner sides of the guide plates 6. The first guiding flanges 421 are coupled to the first guiding grooves 61, and a sliding fit can be formed between the two. When filling the granular materials into the packaging bag, as the granular materials in the packaging bag increase, the moving portion 42 can be gradually pressed down. During the movement of the moving portion 42, the first guiding flanges 421 can slide along the first guiding grooves 61. In this way, it plays a guiding role in the movement of the moving portion 42, making the movement of the moving portion 42 more stable.

[0022] In this embodiment, a slidable baffle 7 is provided in the discharge channel 2. Second guiding flanges 71 protruding from both sides of the baffle 7 are provided, and corresponding second guiding grooves 22 are provided on the inner side of the discharge channel 2. The second guiding flanges 71 are coupled to the second guiding grooves 22 and can form a sliding fit therebetween. By providing the baffle 7, the discharge channel 2 can be closed when the packaging bag is loaded into the port of the discharge channel 2 and when the packaging bag is removed from the port of the discharge channel 2, thereby avoiding the leakage of the pellets in the silo 1. When bagging the pellets, after pouring the pellets to be bagged into the silo 1, the packaging bag is sleeved on the port of the discharge channel 2, and the packaging bag is fixed by the bag pressing mechanism 3. Then, the baffle 7 is slid upward to open the discharge channel 2. Subsequently, under the action of gravity, the pellets in the silo 1 can slide into the packaging bag through the discharge channel 2. After the pellets in the packaging bag are filled, the baffle 7 is slid downward to close the discharge channel 2. Then, after the packaging bag is released by the bag pressing mechanism 3, the packaging bag filled with pellets can be removed.

[0023] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
