DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0019] like Figure 1-Figure 4As shown, a powder bag clamp exhaust structure includes a support sliding assembly, an air pipe 1 and a dust suction assembly. The air pipe 1 is slidably provided on the support sliding assembly, and a cylinder 2 for driving the suction pipe to move up and down is provided on one side of the support sliding assembly; an air pipe joint 3 is provided at the upper end of the air pipe 1, and a dust suction assembly is provided at the lower end of the air pipe 1; the air pipe joint 3 is used to connect to an external exhaust device (such as an exhaust fan 19). When the exhaust device is exhausting air, negative pressure is generated in the air pipe 1, and the dust suction assembly is located inside or above the packaging bag 21, sucking away dust that falls onto the packaging bag 21 from the bag clamp opening and dust that is leaked from the packaging bag 21 due to the rebound of dust in the packaging bag 21;

[0020] The dust suction assembly includes a conical straw 4, a silicone mouth plate 5 and an open pressure plate 6. The upper end of the conical straw 4 is connected to the trachea 1, and the lower end of the conical straw 4 is provided with a silicone mouth plate 5. An open pressure plate 6 is provided below the silicone mouth plate 5. A connecting piece is provided on the open pressure plate 6, and the connecting piece is screwed to the lower end of the conical straw 4; the silicone mouth plate 5 can cooperate with the bag clamp discharge port 20 of the external bag clamp mechanism 22. After the silicone mouth plate 5 rises into place, the bag clamp discharge port 20 of the bag clamp mechanism 22 can be closed; the open pressure plate 6 fixes the silicone mouth plate 5 to the lower end of the conical straw 4.

[0021] Furthermore, the supporting sliding assembly includes a mounting plate 7, which connects the device to an external platform or a bag clamp frame 18; a through hole 8 that can cooperate with the trachea 1 is opened in the middle of the mounting plate 7, and the trachea 1 can pass through the through hole 8 to prevent movement interference; a support frame 9 is provided on the mounting plate 7 outside the through hole 8, and rollers 10 that can cooperate with the trachea 1 are symmetrically arranged inside the support frame 9. The symmetrically arranged rollers 10 guide the trachea 1 to prevent the trachea 1 from tilting when rising or falling.

[0022] Furthermore, rotating shafts 11 are respectively provided at the four inner corners of the support frame 9, and rollers 10 are rotatably installed on the rotating shafts 11. Roller grooves 12 that can cooperate with the trachea 1 are respectively opened on the rollers 10. The shape of the rolling grooves 12 is adapted to the outer contour of the trachea 1 to increase the contact area. The four rollers 10 can better ensure the accuracy of the movement path of the trachea 1.

[0023] Furthermore, the cylinder 2 is connected to the mounting plate 7 using a cylinder bracket 13, and the piston rod of the cylinder 2 is connected to the trachea 1 using a connecting bracket 14. The cylinder bracket 13 ensures a firm connection between the cylinder 2 and the mounting plate 7, and the connecting bracket 14 enables the trachea 1 to move up and down when the piston rod of the cylinder 2 moves up and down.

[0024] Furthermore, a threaded hole 16 capable of cooperating with the connecting piece 15 is opened at the lower end of the conical straw 4. The connecting piece 15 is a connecting bolt. The rod of the connecting piece 15 is screwed into the threaded hole 16, and the silicone mouth plate 5 is firmly fixed to the lower end of the conical straw 4 through the open pressure plate 6.

[0025] Furthermore, the tapered straw 4 is in an inverted "V" shape as a whole, and the lower end opening 17 of the tapered straw 4 is a willow-leaf-shaped opening that is wide in the middle and narrow at both ends. The willow-leaf-shaped opening reduces the lower end surface area of the tapered straw 4 to avoid blocking the material from entering the packaging bag.

[0026] Furthermore, the middle openings of the silicone port plate 5 and the opening pressure plate 6 match the lower end opening 17 .

[0027] Working Principle: When using the utility model, first use the mounting plate 7 to install the support sliding assembly on the external platform or the bag clamp frame 18, adjust the height of the air pipe 1 so that when the piston rod of the cylinder 2 is extended, the silicone port plate 5 can seal the bag clamp discharge port 20;

[0028] When the packaging bag 21 is loaded and packaged, the cylinder 2 contracts, the air pipe 1 drives the silicone mouth plate 5 to descend, the bag clamp discharge port is opened, and the dust suction component is extended into the opened packaging bag 21. At this time, the loading operation can be carried out. While the loading work is in progress, the exhaust fan 19 works, and a negative pressure is formed inside the air pipe 1. The conical suction pipe 4 of the dust suction component is used to suck away the dust rebounding from the packaging bag 21; when the packaging bag 21 completes the loading operation, the piston rod of the cylinder 2 is extended, and the silicone mouth plate 5 closes the bag clamp discharge port 20 again. When the piston rod of the cylinder 2 rises, it drives the dust suction component to rise. During the rising process of the conical suction pipe 4, the negative pressure in the conical suction pipe 4 can suck away the dust floating above the packaging bag 21, thereby achieving the effect of removing dust from the bag mouth of the packaging bag 21.

[0029] It is understood that the above embodiments are merely exemplary embodiments for illustrating the principles of the present invention, and the present invention is not limited thereto. Those skilled in the art may make various modifications and improvements without departing from the spirit and substance of the present invention, and such modifications and improvements are also considered to be within the scope of protection of the present invention.
