In this way, the material moving rack 811 is arranged to install the material moving and clamping parts 812 and the first material moving and clamping driving device 813, and the two material moving and clamping parts 812 are arranged to clamp the film bag. At the same time, the first material moving and clamping driving device 813 is arranged to drive the two material moving and clamping parts 812 to move and clamp the film bag, so that the material moving mechanism 8 can transfer the film bag.

[0094] Furthermore, the first material moving and clamping driving device 813 includes a first material moving driving motor arranged on the material moving frame 811, and two material moving gears meshing with each other, the two material moving gears are respectively arranged on two material moving clamping parts 812, and the first material moving driving motor drives one of the material moving clamping parts 812. In this way, the first material moving driving motor is arranged so as to drive the corresponding material moving clamping part 812 to rotate, and at the same time, the two material moving gears are arranged so as to enable the two material moving clamping parts 812 to rotate synchronously.

[0095] Furthermore, the material moving clamping portion 812 can be fixedly installed on the material moving frame 811, or can be movably installed on the material moving frame 811. The utility model does not limit this. Specifically, in the present embodiment, the material moving clamping structure 81 also includes a material moving seat 814 and a second material moving clamping driving device 815. The material moving seat 814 is movably installed on the material moving frame 811 along the second horizontal direction. The two material moving clamping portions 812 are movably installed on the material moving seat 814. The second material moving clamping driving device 815 is arranged on the material moving frame 811 and is driven and connected to the material moving seat 814. In this way, the material moving seat 814 is provided to install the material moving clamping portion 812, and the second material moving clamping driving device 815 is provided to drive the material moving seat 814 to move, so as to drive the material moving clamping portion 812 to move, so that the two material moving clamping structures 81 can flatten the bag mouth for subsequent loading of the film bag. It is understandable that the second material moving and clamping driving device 815 can be a pneumatic cylinder, an oil cylinder or an electric push rod, etc., and the present invention does not limit this.

[0096] In one embodiment of the utility model, the two material transfer clamping parts 812 and the first material transfer clamping driving device 813 are correspondingly arranged as a material transfer clamping group, and three material transfer clamping groups are arranged, and the three material transfer clamping groups are arranged at intervals along the first horizontal direction. In this way, by setting up three material transfer clamping groups, the film bags on the three workstations can be clamped at the same time, so that the material transfer mechanism 8 can transfer the film bags on the three workstations at the same time, thereby helping to improve the material transfer efficiency of the material transfer mechanism 8.

[0097] In one embodiment of the utility model, among the three material moving and clamping groups, the material moving and clamping group in the middle is set as the first material moving and clamping group 819, the material moving and clamping structure 81 also includes a material moving knife 816 and a third material moving and clamping driving device 817, the material moving knife 816 is movably installed on the material moving frame 811, and is set corresponding to the first material moving and clamping group 819, the third material moving and clamping driving device 817 is set on the material moving frame 811, and is driven and connected to the material moving knife 816, when the film bag is moved from the bag opening station to the unloading station, the third material moving and clamping driving device 817 The third material moving and clamping drive device 817 drives the material moving knife 816 to be inserted into the film bag to stabilize the bag opening so that the material unloading mechanism 6 can be inserted into the film bag. At the same time, the first material moving and clamping drive device 813 drives the two material moving clamping parts 812 to move to clamp the film bag so that the material unloading mechanism 6 can inject material into the film bag. In this way, by arranging the material moving knife 816 and the third material moving and clamping drive device 817, when the film bag is in the unloading station, the material unloading mechanism 6 is assisted in loading the material, thereby helping to improve the stability of the material unloading mechanism 6 in injecting the material.

[0098] The material transfer knife 816 can move in a variety of ways. For example, the material transfer knife 816 can move in a straight line in the up and down directions. However, since the material transfer knife 816 mainly works when the film bag is in the unloading station, if the knife moves in a straight line, it is easy to interfere with the first material transfer clamping group 819. For this reason, in the present embodiment, the material transfer clamping structure 81 also includes a material transfer connecting piece 818, and the middle part of the material transfer connecting piece 818 is rotatably mounted on the material transfer frame 819 around an axis extending along the second horizontal direction. 11. The material moving knife 816 is arranged at one end of the material moving connecting piece 818, and the third material moving clamping driving device 817 drives the other end of the material moving connecting piece 818. In this way, by setting the material moving connecting piece 818, the third material moving clamping driving device 817 can drive the material moving knife 816 to rotate, so that the material moving knife 816 can avoid the first material moving clamping group 819 when moving, so as to avoid interference between the material moving knife 816 and the first material moving clamping group 819.

[0099] It is understandable that there are many types of the third material moving and clamping driving device 817, for example, it can be a driving motor, it can also be a driving cylinder, etc., and the present utility model does not limit this.

[0100] Since the film bag is heavy after loading, if only one material moving and clamping group is provided on one side of the film bag, the clamping force of the material moving and clamping part 812 is too large, and the film bag is easily damaged when the film bag is transferred. For this reason, in the present embodiment, among the three material moving and clamping groups, the material moving and clamping group on the outer side is provided as the second material moving and clamping group, and the material moving and clamping structure 81 includes a material moving and clamping plate 851 and a fourth material moving and clamping driving device 852, and the material moving and clamping plate 851 is movably mounted on the material moving frame 811. And corresponding to the second material moving and clamping group, the fourth material moving and clamping driving device 852 is arranged on the material moving frame 811, and drives the material moving and clamping plate 851. In this way, by setting the material moving and clamping plate 851, the material moving and clamping structure 81 can clamp the film bag filled with material. At the same time, by setting the fourth material moving and clamping driving device 852, so as to drive the material moving and clamping plate 851 to move, the two material moving and clamping plates 851 on the two material moving and clamping structures 81 can clamp the film bag.

[0101] It should be noted that the material moving clamping plate 851 has multiple movable modes. The material moving clamping plate 851 can be installed on the material moving rack 811 in a horizontal direction, or can be installed on the material moving rack 811 in a rotatable manner along an axis extending horizontally, etc. The present invention does not limit this. Furthermore, the fourth material moving clamping drive device 852 can be a driving cylinder or a driving oil cylinder, etc. The present invention does not limit this.
