Materials can be divided into solid materials, granular materials, powder materials, liquid materials, etc. The equipment used for packaging different types of materials varies greatly, and the packaging of materials will directly affect the subsequent storage and transportation of materials. It also involves the packaging rate, packaging accuracy, packaging loss and other issues during the packaging process.

[0003] For example, the existing patent: CN220130476U discloses a powder filling device, which adopts a combination of impeller filling and spiral filling, realizing both the fast filling characteristics of impeller filling and the precise metering characteristics of spiral filling;

Due to the different angles of the discharge bin and the particle size of the material, when transporting materials to the spiral bin, there are often problems such as poor flow, uneven flow and residue on the wall of the bin, which will lead to the problem of inaccurate material transport in the spiral filling bin. In response to the above problems, the inventor has designed a filling device for a precise fixed weight packaging machine. Utility Model Content

DETAILED DESCRIPTION

[0021] See also Figure 1-3 , the utility model provides the following technical solutions:

[0022] Specifically, it refers to a filling device of a precision fixed-weight packaging machine, including an impeller bin 1 and a spiral discharge pipe 3, a feed bin 2 is installed on the impeller bin 1, a connecting pipe 4 is fixedly connected between the impeller bin 1 and the spiral discharge pipe 3, the connecting pipe 4 is respectively connected with the impeller bin 1 and the inside of the spiral discharge pipe 3, an impeller filling structure is arranged in the impeller bin 1, and the impeller filling structure is a known technology in the existing patent: CN220130476U, which will not be described in detail here, a servo motor 5 is arranged on the side of the spiral discharge pipe 3 away from the discharge port, a spiral rod 6 is arranged in the spiral discharge pipe 3, one end of the spiral rod 6 rotates to penetrate the outer surface of the spiral discharge pipe 3, and the spiral rod 6 is installed with the output shaft of the servo motor 5 through a coupling;

[0023] When in use, granular or powdered raw materials are poured into the feed bin 2, the impeller filling structure in the impeller bin 1 operates, and the raw materials are conveyed into the connecting pipe 4, and at the same time the servo motor 5 is started, thereby synchronously driving the screw rod 6 to rotate, so that the raw materials can be accurately conveyed and filled;

[0024] Specifically, a spiral block 7 is fixedly connected to the side of the connecting pipe 4, a twisted rod 8 is arranged in the connecting pipe 4, one end of the twisted rod 8 penetrates the outer surface of the spiral block 7, and a twisted groove adapted to the twisted rod 8 is opened in the spiral block 7, one end of the twisted rod 8 located in the connecting pipe 4 is fixedly connected to a rotating shaft 9, and a plurality of stirring blades 10 are fixedly connected to the outer surface of the rotating shaft 9;

[0025] Therefore, when in use, by pushing the twisted rod 8 to move horizontally, the twisted rod 8 rotates under the restriction of the twist groove, and the rotating shaft 9 synchronously drives the stirring blade 10 to rotate in the connecting pipe 4. This rotating structure is used to force the material to be transported to the next process, thereby avoiding the phenomenon of directly filling the material into the spiral discharge pipe 3 and causing blockage, further ensuring the accuracy of the spiral rod 6 in transporting the material, with a simple structure and strong practicality.

[0026] Specifically, one end of the twisted rod 8 outside the spiral block 7 is rotatably connected to a connecting plate 11, and a spring 12 is fixedly connected between the connecting plate 11 and the spiral block 7. The spring 12 is movably sleeved on the outer surface of the twisted rod 8. When the spring 12 is not squeezed, the spring 12 will form a thrust on the connecting plate 11, so that the initial position of the connecting plate 11 is away from the spiral block 7.

[0027] Specifically, a rotating seat 13 is fixedly connected to the side of the connecting pipe 4, and a rotating push plate 14 is rotatably connected to the rotating seat 13, and one side of the rotating push plate 14 contacts the side of the connecting plate 11 facing away from the twisted rod 8;

[0028] Specifically, a rotating disk 15 is fixedly sleeved on the outer surface of one end of the spiral rod 6 outside the spiral discharge pipe 3, and the other side of the rotating push plate 14 contacts and slides with the side of the rotating disk 15, and an arc-shaped protrusion 16 is fixedly connected to the side of the rotating disk 15, and the other side of the rotating push plate 14 also contacts the arc surface of the arc-shaped protrusion 16;

[0029] When the servo motor 5 drives the screw rod 6 to rotate, the rotating disk 15 rotates synchronously, and the rotating push plate 14 slides on the side of the rotating disk 15. When the rotating push plate 14 contacts the arc surface of the arc-shaped protrusion 16, the arc-shaped protrusion 16 will form a thrust on the rotating push plate 14, so that the rotating push plate 14 rotates clockwise with the rotating seat 13 as the rotation point. Therefore, the other side of the rotating push plate 14 will form a thrust on the connecting plate 11, so that the connecting plate 11 is displaced to one side of the spiral block 7. At the same time, the spring 12 is forced to contract, thereby achieving the purpose of controlling the displacement of the twisted rod 8. When the arc-shaped protrusion 16 is no longer in contact with the rotating push plate 14, the spring 12 loses its extrusion, so that the spring 12 pushes the connecting plate 11 to move to the initial position. Through the above structure, the rotation of the screw rod 6 can be combined to achieve the control of the displacement and rotation of the twisted rod 8, and it can operate synchronously with the screw rod 6 without the need for additional electric components to control, thereby improving the environmental value of the structure.

[0030] The working principle of the filling device of the precision weight-fixed packaging machine provided by the utility model is as follows: granular or powdered raw materials are poured into the feed bin 2, the impeller filling structure in the impeller bin 1 operates, and the raw materials are transported into the connecting pipe 4, and the servo motor 5 is started, thereby synchronously driving the screw rod 6 to rotate;

[0031] The rotating disk 15 rotates synchronously, and the rotating push plate 14 slides on the side of the rotating disk 15. When the rotating push plate 14 contacts the arc surface of the arc-shaped protrusion 16, the arc-shaped protrusion 16 will form a thrust on the rotating push plate 14, so that the rotating push plate 14 rotates clockwise with the rotating seat 13 as the rotation point. Therefore, the other side of the rotating push plate 14 will form a thrust on the connecting plate 11, so that the connecting plate 11 is displaced to one side of the spiral block 7. At the same time, the spring 12 is forced to contract, so that the twist rod 8 rotates under the restriction in the twist groove. At the same time, the rotating shaft 9 synchronously drives the stirring blade 10 to rotate in the connecting pipe 4. When the arc-shaped protrusion 16 is no longer in contact with the rotating push plate 14, the spring 12 loses its extrusion, so that the spring 12 pushes the connecting plate 11 to move to the initial position.
