[0019] After the chrysanthemum is processed in the factory, in order to prolong the shelf life and freshness of the chrysanthemum and other mobile solid small particle materials, facilitate storage and better adapt to the needs of consumers at different levels, the chrysanthemum is sealed and packaged in a packaging bag after a series of processing.

[0020] In this embodiment, a rotating disc type packaging machine is arranged on the machine table, which is mainly used for bagging chrysanthemums. When the chrysanthemums are quantitatively packaged, the packaging bags are first sent one by one and in order to the bag clamping station of the packaging machine by using the bag feeding device.

[0021] When the bag is fed, a packaging bag is first taken from the bag placing bin by using the bag taking assembly and moved to the bag taking station, and then the packaging bag is clamped by using the clamping hand and sent to the bag clamping station. Specifically, when the bag is fed by using the clamping hand, the rotating assembly drives the swing arm to rotate backward, and the two clamping hands are in an open state. In this process, under the action of the guide rod, the bag clamping arm rotates reversely, that is, the clamping hand rotates backward. When the clamping hand rotates to the position, the bag opening of the packaging bag is located between the two clamping hands, the clamping hand clamps the packaging bag, and then the rotating assembly drives the swing arm to rotate forward, and the bag clamping arm rotates forward under the drive of the guide rod, that is, the clamping hand rotates forward. When the swing arm rotates to the position, the clamping hand rotates to the bag clamping station, and the bag clamping assembly on the packaging frame clamps the packaging bag. Then the clamping hand is opened, and the next packaging bag is taken and clamped.

[0022] In the structure, when the rotating assembly drives the swing arm to rotate, the driving motor drives the rotating shaft to rotate, the rotating disc rotates, the roller drives the rotating plate to rotate up and down under the action of the cam groove, the connecting plate rotates up and down, and the swing arm rotates forward and backward to realize the continuous bag feeding effect of the clamping hand, thereby greatly improving the bag feeding efficiency.

[0023] In addition, as Figure 1 A pair of front and rear limiting columns 18 are arranged on the stand 1, and the two limiting columns are used to limit the rotating angle of the swing arm, so that the clamping hand can be accurately rotated to the corresponding station.

[0024] As a preferred structure, as Figure 1 , Figure 4 The bag storage bin includes a fixed frame 19, a loading plate 20 arranged on the fixed frame 19, a bag taking opening 21 arranged on the loading plate 20, a pair of left and right side plates 22 arranged on the loading plate 20, a baffle 23 formed by bending the front end of the side plate 22 inward, a connecting plate 24 arranged at the tail of the loading plate 20, a blocking frame 25 formed at the front end of the connecting plate 24, and a blocking strip 26 arranged at the front end of the blocking frame 25.

[0025] In the device, the bag storage bin is used to stack the packaging bags, and the bag opening of the packaging bag is arranged forward. The bag storage bin includes the fixed frame, the loading plate arranged on the fixed frame, a pair of left and right side plates arranged on the loading plate, and a baffle formed at the front end of the side plate and arranged in the loading plate. The side plate, the blocking frame form a bag storage area, and the stacked packaging bags are arranged in the bag storage area. The front end of the loading plate and the blocking strip support the packaging bags respectively.

[0026] In addition, a pair of adjusting grooves 27 are arranged on the left and right sides of the loading plate 20, a waist round hole 28 is arranged on the side plate 22 corresponding to the same side adjusting groove, a locking bolt (not shown in the figure) is inserted into the waist round hole 28, the locking bolt is locked after passing out of the adjusting groove, a long groove 29 is arranged on the connecting plate 24, and a fixing bolt is inserted into the long groove 29 and locked after passing out of the loading plate 20.

[0027] In the device, the size of the bag storage area can be adjusted according to the specifications of the packaging bag. If the width of the bag storage area is to be adjusted, first loosen all the locking bolts, at this time the side plate can be moved inward, the width of the bag storage area gradually decreases until the adjustment is completed, and then all the locking bolts are tightened. If the length of the bag storage area is to be adjusted, similarly, first loosen the fixing bolt, at this time the connecting plate is pushed forward, the length of the bag storage area gradually decreases until the adjustment is completed, and then the fixing bolt is tightened. It can be seen that the whole adjustment process is relatively simple.

[0028] Further, as a preferred structure, the bag taking assembly comprises a bag taking cylinder 30 mounted on the machine table 1, and a suction disc holder 31 is arranged on the driving shaft of the bag taking cylinder 30, and the suction disc holder 31 is used for mounting a suction disc assembly (not shown in the figure). Figure 1 , Further, as a preferred structure, the bag taking assembly comprises a bag taking cylinder 30 mounted on the machine table 1, and a suction disc holder 31 is arranged on the driving shaft of the bag taking cylinder 30, and the suction disc holder 31 is used for mounting a suction disc assembly (not shown in the figure).

[0029] When the bag taking assembly is used to take the bag, at this time, the bag taking cylinder drives the suction disc holder to move upwards, the suction disc assembly passes through the bag taking opening and adsorbs the lowermost packaging bag, the bag taking cylinder drives the suction disc holder to move downwards until the suction disc holder moves to the bag taking station, and then the clamping hand clamps the packaging bag and moves to the bag clamping station.

[0030] The above only describes the preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
