[0030] Furthermore, the gate mechanism 3 also includes two connecting plates 3-2 respectively arranged on both sides of the arc plate 3-1; one end of the two connecting plates 3-2 are connected to the arc plate 3-1, and the other end is provided with a mounting shaft 3-3 rotatably connected to the outer shell 1; the two mounting shafts 3-3 are connected to the outer shell 1 through a bearing seat, and one of the mounting shafts 3-3 extends out of the outer shell 1; a handle 3-4 is provided on the end of the mounting shaft 3-3 extending out of the outer shell 1, and the mounting shaft 3-3 is driven to rotate by the handle 3-4, so that the connecting plate 3-2 drives the arc plate 3-1 to rotate, thereby opening and closing the outlet of the feed gate 2, so that the arc plate 3-1 and the outlet of the feed gate 2 are frictionless, thereby further avoiding leakage.

[0031] Furthermore, a locking shaft 3-5 is threadedly connected to one of the connecting plates 3-2 on the outer shell 1; the inner end of the locking shaft 3-5 is provided with a silicone pad 3-6 in contact with the connecting plate 3-2, and the other end is provided with a holding knob 3-7. By rotating the holding knob 3-7, the silicone pad 3-6 at the inner end of the locking shaft 3-5 is in contact with the connecting plate 3-2, thereby limiting the connecting plate 3-2, thereby facilitating the adjustment of the position of the arc plate 3-1 and realizing the flow regulation of the feed gate 2.

[0032] Furthermore, when the arc plate 3-1 closes the outlet of the feed gate 2, both ends of the arc plate 3-1 cover the outlet of the feed gate 2, so that the arc plate 3-1 can completely cover the outlet of the feed gate 2, further avoiding leakage.

The arc plate 3-1 is eccentrically arranged with the outlet of the feed gate 2, so that the arc plate 3-1 is more closely fitted with the outlet of the feed gate 2 when closed, so that the arc plate 3-1 has good sealing performance when closing the outlet of the feed gate, and the problem of material leakage is solved. At the same time, when the arc plate 3-1 is opened, there is no friction between it and the outlet of the feed gate 2, which avoids the situation that the arc plate 3-1 leaks due to wear. In addition, a locking shaft 3-5 is provided, and by rotating the holding knob 3- 7 makes the silicone pad 3-6 at the inner end of the locking shaft 3-5 contact with the connecting plate 3-2, thereby limiting the connecting plate 3-2, so as to facilitate the adjustment of the position of the arc plate 3-1, realize the flow adjustment of the feed gate 2, and at the same time form a cavity 1-1 between the outer wall of the feed gate and the inner wall of the outer shell 1; the side wall of the shell is also provided with a suction interface 1-2 connected to the cavity 1-1, which can be connected to a suction device, and particles with heavy specific gravity can fall into the packaging bag under the action of gravity, while dust particles with light specific gravity will be cleaned by the suction device through the suction interface 1-2, thereby cleaning dust during the packaging process to avoid dust harm to operators.
