[0066] A first rotating disk 52, which rotates around a center of a circle and is located below the barrel 51;

[0067] A plurality of quantitative output mechanisms 53, which are horizontally mounted on the first rotating disk 52 along the circumferential direction and are connected to the barrel 51 through a conduit, and each quantitative output mechanism 53 is provided with a rotatably mounted switch member 54;

[0068] The first toggle assembly 55 and the second toggle assembly 56 are respectively disposed at two sides of the first rotating disk 52 and are located directly above the switch member 54;

[0069] When the first rotating disk 52 rotates, it drives the quantitative output mechanism 53 to revolve around its center. Each switch member 54 has a first state in which the quantitative output mechanism 53 is opened and the material is discharged by contacting the first toggle assembly 55 during the rotation process, and a second state in which the quantitative output mechanism 53 is closed and the discharge is stopped by contacting the second toggle assembly 56. The filling device of the present technical solution can automatically complete the filling process of liquid material packaging and can fine-tune the filling amount accuracy during the operation of the equipment. Due to the eccentric design of the first driving mechanism or the second driving mechanism, the connection state conversion of the piston cylinder and the three-way valve core, and the cooperation between the first toggle assembly and the second toggle assembly and the switch member, each time the piston member extracts a quantitative material, the first toggle assembly opens the switch member, converts the connection state of the piston cylinder and the three-way valve core, and the piston member then discharges the material through the conduit and the feeding head to the packaging bag below. After the discharge, the second toggle assembly closes the switch member, converts the connection state of the three-way valve core and the piston cylinder, and the piston member extracts a quantitative material again to fill the piston cylinder, and the quantitative material is output repeatedly, which has the advantages of good practicality and precise filling.

[0070] The quantitative output mechanism 53 includes:

[0071] A piston cylinder 531, in which a piston member 532 is provided for horizontal reciprocating motion;

[0072] A three-way valve core 533, which is rotatably mounted in the piston cylinder 531 and has a distal end extending out of the piston cylinder 531 and fixedly connected to the switch member 54;

[0073] The circumferential outer wall of the piston cylinder 531 is provided with a first feed hole 5311 connected to the conduit and a first discharge hole 5312 connected to the feeding head;

[0075] When the switch element 54 is in the second state, the first feed hole 5311 is connected with the second feed hole 5331, while the first discharge hole 5312 and the second discharge hole 5332 are not connected, and the piston element 532 moves upward through the first feed hole 5311 and the second feed hole 5331 to draw the material into the piston cylinder 531; when the switch element 54 is in the first state, the first discharge hole 5312 is connected with the second discharge hole 5332, while the first feed hole 5311 and the second feed hole 5331 are not connected, and the piston element 532 moves downward through the first discharge hole 5312 and the second discharge hole 5332 to discharge the material from the piston cylinder 531. When the piston moves toward the center of the first turntable and fills the piston cylinder with material, the first feed hole and the second feed hole are in a connected state. When the piston moves to the extreme position, the piston cylinder is filled with material. Then the switch touches the first toggle assembly and rotates, so that the first discharge hole and the second discharge hole are in a connected state and the first feed hole and the second feed hole are in a closed state. At this time, the piston moves in the opposite direction to discharge the material through the first discharge hole and the second discharge hole into the packaging bag below. Because the positions of the center of the first turntable and the center of the second turntable remain unchanged, the movement stroke of each piston is the same, and the capacity of each piston cylinder is the same. Therefore, the volume of material discharged from the packaging bag each time is the same.

[0076] In addition, in this embodiment, pipe joints connecting the first discharge hole 5312 and the conduit 534 and the first feed hole 5311 and the conduit 534 are respectively provided between the two. The first feed hole is connected to the barrel through the conduit, and the first discharge hole is connected to the feeding head of the corresponding packaging bag through the conduit.

When passing through the first toggle assembly, the first toggle assembly touches the first toggle portion to rotate the switch member, so that the first discharge hole 5312 is connected with the second discharge hole 5332 and the first discharge hole and the second discharge hole are not connected. When the piston cylinder rotates and passes through the second toggle assembly, the second toggle assembly touches the second toggle portion to rotate the switch member, so that the first feed hole 5311 is connected with the second feed hole 5331 and the first discharge hole 5312 is not connected with the second discharge hole 5332.

[0078] The first toggle assembly 55 comprises:

[0079] A first mounting seat 551, which is fixedly mounted on the column 11 and located above the circumferential edge of the first rotating disk 52;

[0082] The first toggle plate 552 is tilted on a vertical plane, the first turntable 52 drives the switch member 54 to rotate and contacts the first toggle rod 541 when passing through the lower surface of the first toggle plate 552, causing the switch member 54 to rotate to the first state; the rotation of the first turntable drives the piston cylinder to rotate, the first toggle plate is within the range of motion of the switch member, the switch member at the end of the piston cylinder contacts the first toggle plate and is subjected to force, causing the switch member to rotate.

[0083] The third driving member can drive the first toggle plate to move, so that the first toggle plate swings around the hinge point, thereby adjusting the tilt angle of the first toggle plate; thus achieving controllability of opening and closing the switch member.

[0088] The second shifting plate 563 is provided with an arc surface 567 on the lower side facing the switch member 54. When the first rotating disk 52 drives the switch member 54 to rotate and passes through the second shifting plate 563, the arc surface 567 contacts the second shifting rod 542 and rotates the switch member 54 to the second state.

[0089] The rotation of the first turntable drives the piston cylinder to rotate, and the arc surface is located above the movement stroke of the switch member. The switch member at the end of the piston cylinder contacts the arc surface and is subjected to force, causing the switch member to rotate to the second state, wherein the first elastic member provides a pre-tightening force for the second toggle plate to always contact the switch member; in addition, in this embodiment, the second toggle plate is a hinged structure. If the switch member is stuck and cannot rotate, in order to protect the equipment, the second toggle plate can swing to protect the switch member; wherein the limit nut limits the second toggle plate.
