[0045] Optionally, the bag storage area 110 and the bag closing area 130 can be arranged on the left side and the right side of the bag receiving area 120 respectively (for example, as shown in Figure 1 and Figure 2 shown), or the bag storage area 110 and the bag closing area 130 can also be arranged on the right side and the left side of the bag receiving area 120 respectively, which can be set according to actual needs.

[0046] In some embodiments of the present application, as shown in Figure 4 , the bag storage mechanism 200 comprises a bag storage trolley 210 and a bag hanging assembly 220 for hanging the empty packaging bags 1, the bag storage trolley 210 comprises a trolley rack 211 and a moving wheel 212 (for example, a universal wheel) arranged at the bottom of the trolley rack 211, and two pairs of sides of the trolley rack 211 are symmetrically provided with the bag hanging assembly 220. By arranging the bag hanging assembly 220 on the bag storage trolley 210 with the moving wheel 212, since the bag storage trolley 210 can be separated from the rack 100, a plurality of bag storage trolleys 210 can be used in rotation to realize continuous replenishment of the packaging bags 1, and the bag hanging operation can be completed outside the rack 100, so that the operator does not need to enter the inside and there is no safety risk. Specifically, the operator hangs the packaging bags 1 on the bag hanging assembly 220 in advance, and pushes the bag storage trolley 210 into a designated position in the bag storage area 110 of the rack 100 for use; when the packaging bags 1 on the bag storage trolley 210 in the bag storage area 110 are used up, the operator only needs to push out the empty bag storage trolley 210 and replace it with the bag storage trolley 210 hung with the packaging bags 1 prepared in advance, so that the packaging bags 1 can be replenished in a very short time.

[0047] Optionally, the number of packaging bags 1 stored on each bag storage trolley 210 is not limited, and any number of bag hanging assemblies 220 can be arranged according to actual needs, and each pair of bag hanging assemblies 220 corresponds to one packaging bag 1. For example, as shown in Figure 1 , Figure 2 and Figure 4As shown, each storage bag trolley 210 is provided with five pairs of bag hanging assemblies 220, so that five packing bags 1 can be hung on one storage bag trolley 210.

[0048] As Figure 4 As shown, the trolley frame 211 is provided with a guide wheel 230 on each of the two sides parallel to the running direction of the storage bag trolley 210, and the rotation axis of the guide wheel 230 is parallel to the vertical direction. The frame 100 is provided with a guide groove cooperating with the guide wheel 230, the guide groove is located in the storage bag area 110 and extends along the second horizontal direction B which is perpendicular to the first horizontal direction A, and the guide wheel 230 can move along the guide groove. Through the cooperation of the guide groove and the guide wheel 230, the storage bag trolley 210 can be guided to the correct position in the frame 100, and at the same time it can also play a limiting role, so that the storage bag trolley 210 can stably stay at the correct position in the frame 100, preventing the storage bag trolley 210 from deviating, so that the bag supporting mechanism 300 can accurately grab the packing bag 1 on the storage bag trolley 210.

[0049] As Figure 5As shown, in some embodiments of the present application, the bag hanging assembly 220 comprises a hanging plate 221, a baffle 222, an elastic member 223, and a first guide rod 224 and a second guide rod 225, the first guide rod 224 is vertically arranged in the side wall of the trolley frame 211, the two ends of the first guide rod 224 are respectively connected with the hanging plate 221 and the baffle 222, and the hanging plate 221 is located at the inner side of the trolley frame 211, and the baffle 222 is located at the outer side of the trolley frame 211; the second guide rod 225 is parallel to the first guide rod 224, one end of the second guide rod 225 is connected with the side wall of the trolley frame 211 (i.e. the side wall in which the first guide rod 224 is arranged), and the other end of the second guide rod 225 is arranged in the baffle 222, and the elastic member 223 is sleeved on the second guide rod 225 and located between the baffle 222 and the side wall of the trolley frame 211 (i.e. the side wall in which the first guide rod 224 is arranged). Among them, the hanging plate 221 is used for hanging the empty packing bag 1, the first guide rod 224 is used for guiding the movement of the hanging plate 221 and the baffle 222, so as to improve the movement stability of the hanging plate 221 and the baffle 222; the second guide rod 225 is used for guiding the extension movement of the elastic member 223, so as to improve the stability of the elastic member 223 during extension; the elastic member 223 can be a spring, a sponge or other components that can generate elastic restoring force when compressed. Specifically, when it is needed to hang the empty packing bag 1 on the bag hanging assembly 220, first, fold the bag opening of the packing bag 1 outward, then pull the hanging plate 221 to move along the axis direction of the first guide rod 224 towards the inner side of the trolley frame 211, at this time, the elastic member 223 is compressed by the baffle 222, and then the folded edge of the bag opening of the packing bag 1 is hung on the hanging plate 221, then the hanging plate 221 is released, and the baffle 222 drives the hanging plate 221 to move along the axis direction of the first guide rod 224 towards the outer side of the trolley frame 211 under the action of the elastic restoring force of the elastic member 223, so that the hanging plate 221 clamps the folded edge of the bag opening of the packing bag 1 with the inner side of the trolley frame 211, thereby completing the bag hanging operation.

[0050] Optionally, the number of the first guide rod 224 can be one or more than two, for example, as shown, the first guide rod 224 is provided as two, and the second guide rod 225 is located between the two first guide rods 224, and by providing more than two first guide rods 224, the movement stability of the hanging plate 221 and the baffle 222 can be further improved.

By arranging the horizontal moving drive 312 to drive the horizontal moving slide 311 to move along the first horizontal direction A, the lifting slide 321 and the clamping jaw assembly are driven to move between the bag storage area 110 and the receiving area 120 to carry the packing bag 1; by arranging the lifting drive 322 to drive the lifting slide 321 to lift, the clamping jaw assembly is driven to lift to grab the packing bag 1 on the bag storage mechanism 200.

[0052] Specifically, when the receiving area 120 needs to replace the empty packing bag 1, the horizontal moving drive 312 drives the horizontal moving slide 311 to drive the lifting slide 321 and the clamping jaw assembly to move along the first horizontal direction A to the bag storage area 110, then the lifting drive 322 drives the lifting slide 321 to drive the clamping jaw assembly to descend together to grab the packing bag 1 on the bag storage mechanism 200, after the clamping jaw assembly grabs the packing bag 1, the lifting drive 322 drives the lifting slide 321 to drive the clamping jaw assembly to ascend, then the horizontal moving drive 312 drives the horizontal moving slide 311 to drive the lifting slide 321 and the clamping jaw assembly to move along the first horizontal direction A to the receiving area 120 to carry the empty packing bag 1 to the receiving area 120, finally the clamping jaw assembly opens the bag opening of the packing bag 1 to receive the goods, the taking and opening mechanism 300 realizes automatic carrying and opening of the packing bag 1, improves the carrying speed of the packing bag 1, and reduces the labor intensity and labor cost of the operator.
