Description

Technical Field

[0001] The utility model relates to the technical field of filling machines, in particular to a nutrient preparation production filling machine. Background Art

[0002] Filling machines are mainly a small category of packaging machines. From the perspective of material packaging, they can be divided into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines. In the production process of nutritional supplements, filling machines are needed to fill them for easy transportation and sales.

[0003] A fully automatic filling machine for cream production is disclosed in a Chinese patent document with publication number CN214875751U, including a filling assembly, wherein the filling assembly includes a plurality of filling cylinders, wherein the plurality of filling cylinders are fixed at one end of a plurality of fixed plates, wherein the bottoms of the plurality of filling cylinders are threadedly connected to filling nozzles, wherein one side of the upper end of the filling cylinder is connected to a first one-way valve, wherein the first one-way valve is connected to an extrusion cylinder, wherein a piston rod is movably connected inside the extrusion cylinder, wherein one end of the piston rod is connected to a piston, wherein a raw material pipe is installed at the upper end of the extrusion cylinder, wherein the raw material pipe is connected to a plurality of branch pipes, wherein one end of the branch pipe is connected to a second one-way valve, and wherein the second one-way valve is connected to the extrusion cylinder. The servo motor pushes the threaded push plate through the forward and reverse rotation of the screw. The reciprocating motion of the push plate pushes the piston rod to extrude the cream raw material for filling. When the piston rod is pulled back, the first one-way valve is closed and the second one-way valve is opened to suck in the cream. The amount of cream sucked in is controlled by the number of rotations of the screw. When the cream is extruded, the second one-way valve is closed and the first one-way valve is opened, and the cream is squeezed out through the filling nozzle.

[0004] The disadvantage of the above disclosed solution is that when the cream is filled through the filling nozzle, the cream is squeezed out by a certain pressure, so the cream is easily splashed out through the filling nozzle, resulting in a waste of cream. Utility Model Content

[0022] The feeding mechanism includes a feeding assembly and a pushing assembly. The feeding assembly includes two sleeves 8. The two sleeves 8 correspond to the two fixed cylinders 11 one by one. The sleeves 8 are arranged horizontally. The sleeves 8 are connected to the inside of the corresponding fixed cylinders 11 through a connecting pipe. The top of the sleeve 8 is connected to a feeding pipe 10. A one-way valve 9 is installed on the feeding pipe 10. The function of the one-way valve 9 is to allow the nutrient to enter the sleeve 8 only from the feeding pipe 10. A second piston is slidably installed in the sleeve 8, and a push rod 7 is fixedly installed on one side of the second piston. One end of the push rod 7 extends to the outside of the sleeve 8.

[0023] The push assembly is mounted on the bracket 1, and is connected to the push rod 7 and drives the push rod 7 to move back and forth. The push assembly includes a motor 4, which is fixedly mounted on the upper surface of the bracket 1, and a threaded rod 5 is fixedly mounted on the output end of the motor 4, and the threaded rod 5 is arranged horizontally. A push plate 6 is sleeved on the outer circumference of the threaded rod 5, and the push plate 6 is threadedly mounted with the threaded rod 5, and the push plate 6 is fixedly mounted with one end of the push rod 7.

[0024] The bracket 1 is fixedly mounted with two symmetrically arranged guide rails 3, and the ends of the two guide rails 3 away from the motor 4 are fixedly mounted with the fixed plate, and the guide rails 3 are slidably engaged with the push plate 6. Two T-shaped sliders are fixedly mounted at the bottom of the push plate 6, and the two sliders are slidably engaged with the corresponding guide rails 3, so that the push plate 6 is more stable when moving, and the push plate 6 is kept balanced under the action of the guide rails 3.

[0025] The bottom of the fixed cylinder 11 is open, and a slide groove is provided in the cylinder wall of the fixed cylinder 11 along its circumference, and the slide groove extends downward along the length direction of the fixed cylinder 11 and communicates with the outside of the fixed cylinder 11. A movable cylinder 16 is slidably installed in the slide groove, and a limiting ring 13 is fixedly installed on the inner wall of the slide groove to limit the movable cylinder 16. An annular convex edge is fixedly installed on the top of the inner wall of the movable cylinder 16, and the convex edge cooperates with the limiting ring 13 to prevent the movable cylinder 16 from falling out of the slide groove.

[0026] The inner wall of the chute is also provided with a discharge hole 12 connected to the interior of the fixed cylinder 11, and the discharge hole 12 is located below the limit ring 13. A first piston 15 is slidably installed in the fixed cylinder 11, and a spring 14 is fixedly installed between the first piston 15 and the top wall in the fixed cylinder 11, one end of the spring 14 is fixedly installed with the first piston 15, and the other end of the spring 14 is fixedly installed with the top wall in the fixed cylinder 11. The bottom of the first piston 15 is fixedly installed with the bottom wall in the movable cylinder 16, and a discharge pipe 17 connected to the interior of the movable cylinder 16 is installed at the bottom of the movable cylinder 16, and the discharge pipe 17 is funnel-shaped for easy discharge.

[0027] A groove is provided at the bottom of the inner wall of the fixed cylinder 11 along its circumference, and the groove is located below the connecting pipe connecting the sleeve 8 and the fixed cylinder. The top wall of the groove forms a step with the inner wall of the fixed cylinder 11, and the inner wall of the groove is slidably mounted with the first piston 15. The top wall of the groove serves as a limit for the first piston 15. The groove is connected to the inside of the movable cylinder 16 through the discharge hole 12. When no material is discharged, the top surface of the first piston 15 is located above the discharge hole 12, and the first piston 15 blocks the discharge hole 12.

[0028] The working principle of a nutrient preparation production filling machine provided by the utility model is as follows:

[0029] In the initial state, the top wall of the first piston 15 fits with the top wall of the groove, and the first piston 15 blocks the discharge hole 12 .

[0030] During filling, the feed pipe 10 is connected to the external conveying mechanism and the raw materials are introduced. The raw materials enter the sleeve 8 through the one-way valve 9. The motor 4 is started, and the output end of the motor 4 rotates clockwise to drive the threaded rod 5 to rotate. The threaded rod 5 rotates and drives the push plate 6 to move toward the fixed cylinder 11. The push plate 6 pushes the push rod 7 to move. The push rod 7 pushes the second piston to squeeze the raw materials in the sleeve 8. At this time, the one-way valve 9 is closed. At the same time, the raw materials are squeezed and pressure is generated on the first piston 15. When the pressure is greater than the tension of the spring 14, the spring 14 is stretched, and the raw materials push the first piston 15 to move downward. The first piston 15 drives the movable cylinder 16 to move downward, and the discharge pipe 17 on the movable cylinder 16 extends into the container mouth. The filling amount is controlled by adjusting the number of revolutions of the motor 4.

[0031] At the same time, after the convex edge of the movable cylinder 16 is in contact with the stop ring 13, the movable cylinder 16 no longer moves downward, and the top surface of the first piston 15 moves below the discharge hole 12, and the first piston 15 no longer blocks the discharge hole 12. Then the raw material is squeezed out from the discharge hole 12 and filled into the container along the inner wall of the movable cylinder 16 and the discharge pipe 17. This prevents the raw material from splashing when entering the container from the discharge pipe 17.

[0032] When the motor 4 rotates a preset number of times and the container is filled, the output end of the motor 4 is controlled to rotate counterclockwise, and the threaded rod 5 drives the push rod 7 to pull back through the push plate 6, and the push rod 7 drives the second piston to pull back. At this time, the raw material is no longer squeezed, so that the pressure of the raw material on the first piston 15 is reduced to less than the tension of the spring 14, and the spring 14 retracts, so that the first piston 15 is pulled upward by the spring 14 until the top surface of the first piston 15 fits with the top wall of the groove, and the first piston 15 blocks the discharge hole 12 again. When the second piston is pulled back, the one-way valve 9 opens and the raw material is sucked into the sleeve 8, and the raw material enters the sleeve 8 through the feed pipe 10. The suction amount is controlled by adjusting the number of turns of the motor 4. After the output end of the motor 4 rotates a preset number of times, the above action is repeated to continue the filling work.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
