[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0018] Reference Figure 1 and Figure 2, a bag mouth clamping device, the device comprises a feeding pipe 1 and a dust collecting pipe 3 sleeved outside the feeding pipe 1, a dust cover 2 which cooperates with the pipe wall of the feeding pipe 1 and seals is arranged on the top of the dust collecting pipe 3, a dust collecting pipe 5 is arranged on the dust cover 2, and a clamping assembly for tightening the bag mouth is arranged at the bottom of the dust collecting pipe 3; the clamping assembly comprises a clamping ring 4 sleeved on the dust collecting pipe 3 and a clamping groove 8 which cooperates with the clamping ring 4, the clamping groove 8 is arranged on the circumference of the outer pipe wall of the dust collecting pipe 3, and a power mechanism which sends the clamping ring into the clamping groove to press the bag mouth is installed on the outer pipe wall above the clamping groove 8, and the power mechanism is a cylinder body such as a cylinder 7, an oil cylinder, an electric cylinder, etc., and can also be any power structure disclosed in the prior art that can make the clamping ring move up and down.

[0019] A plurality of suction blocks 6 for pressing the bag opening are provided at the lower part of the dust collecting tube 3. The suction blocks 6 are arranged along the circumference of the dust collecting tube 3. There are three suction blocks, which are evenly arranged along the circumference of the dust collecting tube; each suction block 6 is provided with two magnetic blocks, one of which is a fixed magnetic block fixed on the outer wall of the dust collecting tube, and the other is a movable magnetic block hoisted on the outer wall of the dust collecting tube; the movable magnetic block is covered with a silicone skin to prevent wear on the bag opening.

[0020] A conical section inclined toward the center of the dust collecting pipe is provided at the lower part of the pressing groove 8, and a cylindrical section consistent with the diameter of the dust collecting pipe is provided at the upper part of the pressing groove.

[0021] When the bag mouth is assembled, the bag mouth is first manually put on the outside of the dust collecting tube 3 and tied tightly, the bag mouth is pressed by the suction block 6, and then the compression ring 4 is sent to the compression groove 8 by the cylinder 7. The bottom of the compression groove 8 is designed to be sloped. The lower the cylinder is, the narrower the groove is, and the better the compression effect is, thus completing the clamping of the entire bag mouth. Since the compression ring 4 and the compression groove 8 are arranged in a circle along the circumference of the dust collecting tube, the entire bag mouth will be compressed, thereby solving the problem of poor sealing when the bag mouth is clamped, preventing dust from overflowing, and protecting the environment.
