Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1, please refer to Figures 1-4 This utility model provides a technical solution:

[0023] A closing structure for the material inlet of a container bag includes a fixed support plate 1, a fixed support leg 2 fixedly connected to the bottom end face of the fixed support plate 1, a material filling groove 3 extending through the center of the inner side of the fixed support plate 1, a fixed mounting ring 4 fixedly connected to the top end face of the fixed support plate 1, a mounting support plate 5 fixedly connected to the top end face of the fixed support plate 1, a movable clamping plate 6 provided on the top of the fixed support plate 1, an electric telescopic rod 7 fixedly connected to one side of the mounting support plate 5, a movable mounting ring 8 rotatably connected to the bottom end face of the fixed support plate 1, a movable toothed ring 9 fixedly connected to the outer side of the movable mounting ring 8, and a drive motor 10 fixedly connected to the top end face of the fixed support plate 1.

[0024] As a preferred technical solution of this utility model, there are four fixed support legs 2, which are evenly distributed at the four corners of the bottom of the fixed support plate 1, and the other end of each fixed support leg 2 is fixedly connected with an anti-slip block; thus ensuring the stability of the equipment during use.

[0025] As a preferred technical solution of this utility model, the inner diameter of the fixed mounting ring 4 matches the inner diameter of the filling groove 3, and the diameter of the movable mounting ring 8 is larger than the diameter of the fixed mounting ring 4; thus ensuring that the filling and use can be carried out reasonably.

[0026] As a preferred technical solution of this utility model, there are two movable clamping plates 6 arranged symmetrically, and the two movable clamping plates 6 are respectively fixedly connected to the electric telescopic rod 7. Both movable clamping plates 6 are arc-shaped, and the other side of both movable clamping plates 6 is provided with anti-slip pads; this facilitates clamping the bag opening and prevents the bag from falling off during filling.

[0027] Please refer to Example 2 Figure 4 The difference between this embodiment and Embodiment 1 is that:

[0028] As a preferred technical solution of this utility model, the main shaft of the drive motor 10 is fixedly connected to the drive gear 11 through a coupling, and the drive gear 11 is meshed with the movable gear ring 9. The bottom of the fixed support plate 1 is fixedly connected to the mounting bracket 12, and the side of the mounting bracket 12 is rotatably connected to the wire feeding roller 13.
