Preferably, the output end of the control driving unit 342 is rotatably connected to the middle portion of the first material opening and closing member 35, and the control driving unit 342 is a cylinder. When the discharging port of the bagging hopper 31 needs to be opened, the piston rod of the control driving unit 342 is contracted, the contracted piston rod pulls the first material port opening and closing member 35 to rotate counterclockwise, the first gear 343 rotates counterclockwise along with the first material port opening and closing member 35, the counterclockwise first gear 343 drives the second gear 344 to rotate clockwise, the clockwise second gear 344 drives the second material port opening and closing member 36 to rotate clockwise, and the first material port opening and closing member 35 and the second material port opening and closing member 36 are opened to open the discharging port of the bagging hopper 31. The first material opening and closing piece 35 and the second material opening and closing piece 36 rotate synchronously in a gear set meshing mode, the rotation directions of the first material opening and closing piece and the second material opening and closing piece are opposite, the rotation is stable, the synchronism is good, and the opening or closing of the material outlet of the bagging hopper 31 is facilitated.

Specifically, the main body of the control drive unit 342 is rotatably connected to the bagging hopper 31 via a first hinge 345. The structural design enables the control driving unit 342 to have a certain degree of freedom, which is beneficial for the control driving unit 342 to drive the first material opening and closing member 35 and the second material opening and closing member 36 to open or close.

Specifically, the first material opening shutter 35 or the second material opening shutter 36 is provided with a switching block 351, and the output end of the control driving unit 342 is rotatably connected to the switching block 351 via a second hinge 346. This structural design not only is convenient for control drive unit 342's output and first material mouth on-off 35 or the connection of second material mouth on-off 36, still is favorable to control drive unit 342 to drive first material mouth on-off 35 and the opening or closing of second material mouth on-off 36.

Specifically, the number of the transmission assemblies 341 is two, and the two transmission assemblies 341 are respectively located at two sides of the first material opening and closing member 35 or the second material opening and closing member 36. This structural design, structural symmetry is good, and first material mouth opening and closing piece 35 and second material mouth opening and closing piece 36 open or closed stably.

Specifically, the open/close controller 34 further includes a protective cover 38, and the protective cover 38 is covered outside the transmission assembly 341. The protective cover 38 covers the transmission assembly 341 to protect the transmission assembly 341, and has an attractive appearance.

Specifically, both sides of the discharge hole of the bagging hopper 31 are provided with side plates 39, and the top end of the first material opening and closing member 35 and the top end of the second material opening and closing member 36 are rotatably connected with the side plates 39. When the first port opener 35 and the second port opener 36 are closed, the first port opener 35, the side plate 39, and the second port opener 36 close the discharge port of the bagging hopper 31. In the bagging process, the two side plates 39 have the flaring effect on the bag opening of the packaging bag, so that the materials are guided, and the bagging stability is improved.

Specifically, the number of the bagging lifters 32 is two, and output ends of the two bagging lifters 32 are connected to both sides of the bagging hopper 31, respectively. Two bagging lifters 32 synchronous drive bagging hopper 31 goes up and down for bagging hopper 31 atress is even, has improved the stability that bagging hopper 31 goes up and down.

Specifically, the sidewall of the bagging hopper 31 is provided with a connection lug 391, and the output end of the bagging lifter 32 is connected with the connection lug 391. This structural design is convenient for the output of bagging elevator 32 to be connected with bagging hopper 31.

All the technical features in the embodiment can be freely combined according to actual needs.

The above embodiments are preferred implementations of the present invention, and the present invention can be implemented in other ways without departing from the spirit of the present invention.
