Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0018] like Figure 1-Figure 3 As shown, a powder bagging mechanical device comprises a base 1, a driving motor 2, a transmission shaft 3, a large arm 4, a square shaft 5, a small arm 6, a driving cylinder 7 and a pneumatic clamp 8. Two bases 1 are symmetrically arranged, and a transmission shaft 3 is arranged between the bases 1. The base 1 is convenient for the device to be installed on the assembly line equipment;

[0019] A driving motor 2 for driving a transmission shaft 3 is arranged on a base 1;

[0020] A large arm 4 is arranged in the middle of the transmission shaft 3. When the driving motor 2 drives the transmission shaft 3 to rotate, the large arm 4 rotates accordingly.

[0021] A square shaft 5 is provided at the end of the big arm 4, and small arms 6 are provided at both ends of the square shaft 5. When the square shaft 5 rotates, the small arms 6 rotate accordingly;

[0022] A driving cylinder 7 is hinged in the middle of the big arm 4, and a connecting bracket 9 is provided in the middle of the square shaft 5. The piston rod of the driving cylinder 7 is connected to the square shaft 5 by the connecting bracket 9. The driving cylinder 7 drives the square shaft 5 to rotate, which can drive the small arm 6 to rotate;

[0023] Pneumatic clamps 8 are respectively provided at the middle part of the small arm 6 and the end far away from the square shaft 5. The pneumatic clamps 8 are used to clamp the four corners of the bag opening of the packaging bag so that the bag opening remains open and rectangular during the bagging process, and the bag opening is also rectangular when the bag sealing operation is required later.

[0024] Furthermore, a buffer plate 10 is provided at one end of the transmission shaft 3, and a buffer block 11 that can cooperate with the buffer plate 10 is provided at the upper end and the middle part of the base 1, and the buffer block 11 is connected to the base 1 by a limiting plate 12; the cooperation between the buffer plate 10 and the buffer block 11 limits the maximum rotation stroke of the transmission shaft 3 and plays a buffering role.

[0025] Furthermore, a reinforcing rod 13 is provided between the bases 1, and the reinforcing rod 13 strengthens the connection strength between the two bases 1, so that the base 1 can better support the device.

[0026] Furthermore, the forearm 6 includes a first side plate 14 and a second side plate 15, and the first side plate 14 and the second side plate 15 are respectively connected to the transmission shaft 3 by means of a fixing block 16; the first side plate 14 and the second side plate 15 are respectively provided with a hinge plate 17 for fixing the driving cylinder 7, and the driving cylinder 7 is hinged on the hinge plate 17, and no motion interference occurs when the driving cylinder 7 is in motion.

The cooperation between the rotating rod 18 and the bearing 19 enables the square shaft 4 to rotate at the end of the small arm 6.

[0028] Furthermore, both ends of the transmission shaft 3 are circular shafts, and the circumference facilitates the rotation of the transmission shaft 3 between the bases 1; the middle section of the transmission shaft 3 is a prismatic shaft, and the prismatic shaft enables the upper arm 4 to be firmly fixed on the transmission shaft 3 and move accurately.

[0029] Working principle: When the utility model is in use, the base 1 is fixed on the bag opening equipment, the driving motor 2 is activated, the transmission shaft 3 rotates, and the upper arm 4 and the lower arm 6 are swung to the bag opening position (origin) of the packaging bag. After they are in place, the pneumatic clamp 8 is activated to clamp the bag; then, the motor is reversed and the bag is swung to the bag clamping mouth; after the bag clamping mouth clamps the bag, the pneumatic clamp 8 is released, the driving cylinder 7 is activated, the lower arm 6 is lifted upward, and the pneumatic clamp 8 is separated from the packaging bag to avoid interference between the pneumatic clamp 8 and the packaging bag being packaged and the bag clamp; then the upper arm 4 rotates to the origin, the lower arm 6 is lowered, and the next step is continued.
