Description

Technical Field

[0001] This utility model relates to the field of filling technology, specifically to an adjustable speed screw quantitative filling device. Background Technology

[0002] "Filling" generally refers to the process of filling liquid, semi-fluid, or powder materials into containers (such as bottles, cans, bags, etc.), and is widely used in the food, beverage, chemical, and pharmaceutical industries.

[0003] Currently, filling requires the use of quantitative filling equipment. However, current filling equipment lacks the function of completely squeezing out the quantitative material. The material will generally be discharged from the pipe and enter the tank on its own. This state will cause a large amount of material to remain on the inner wall of the discharge pipe. This residual material will cause inaccurate filling and affect the filling quality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an adjustable speed screw quantitative filling device, which can scrape off excess material through a rotating scraper to make the material quantitatively filled, and push out the material remaining on the wall of the quantitative tube through an extrusion column, so as to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: an adjustable speed screw quantitative filling device, including a housing, a quantitative tube communicating with the inner cavity of the housing is installed at one end of the housing, a positioning tube communicating with the inner cavity of the housing is installed at the other end of the housing, the positioning tube is arranged perpendicularly to the quantitative tube, a baffle is provided at the end of the quantitative tube away from the housing, a central column is provided inside the housing, a scraper is installed on the outer ring surface of the central column, an extrusion column is provided in the opening at the end of the positioning tube away from the quantitative tube, and a drive mechanism for moving the extrusion column is installed on the outer end face of the extrusion column.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention discloses an adjustable speed screw quantitative filling device, comprising a housing 1. A quantitative tube 2 communicating with the inner cavity of the housing 1 is installed at one end of the housing 1, and a positioning tube 3 communicating with the inner cavity of the housing 1 is installed at the other end of the housing 1. The positioning tube 3 is arranged perpendicularly to the quantitative tube 2. A baffle 10 is provided at the end of the quantitative tube 2 away from the housing 1. A central column 16 is provided inside the housing 1. A scraper 17 is installed on the outer ring surface of the central column 16. An extrusion column 4 is provided in the opening at the end of the positioning tube 3 away from the quantitative tube 2. A drive mechanism for moving the extrusion column is installed on the outer end face of the extrusion column 4.

[0023] In this embodiment, the driving mechanism includes a lead screw 5, a first motor 6, a positioning plate 7, and a fixing frame 8. One end of the fixing frame 8 is mounted on the housing 1, and the other end extends to the end face of the extrusion column 4 and is fixedly connected to the first motor 6. A lead screw hole is vertically provided on the exposed end face of the extrusion column 4. The rotating shaft of the first motor 6 passes through the fixing frame 8 and is fixedly connected to the lead screw 5 through a coupling. The other end of the lead screw 5 is threaded into the lead screw hole. A positioning groove is provided on one side of the extrusion column 4 located in the lead screw hole. The positioning plate 7 is set in the positioning groove. One end of the positioning plate 7 extends to the outside and is mounted on the fixing frame 8.

[0024] In this embodiment, the central column 16 is located at the center of the inner cavity of the housing 1. A mounting hole is provided at the center of one end of the housing 1. A sealed bearing is installed in the mounting hole. A shaft is installed in the inner ring of the sealed bearing. One end of the shaft is installed on the central column 16. A second motor 18 connected to the shaft is installed at the center of the housing 1.

[0025] In this embodiment, the baffle 10 is bent upward on both sides to form a side, and the metering tube 2 is provided with guide grooves on both sides. A guide strip 11 is installed on the inner side of the side and the guide strip 11 is slidably disposed in the guide groove. A fixing block 12 is installed on one side and a cylinder 14 is installed on the fixing block 12. The outer shell of the cylinder 14 is installed on the metering tube 2. The baffle can be positioned by the guide strip and the positioning groove, so that the baffle can only move back and forth along the guide groove to ensure the stability after installation.

[0026] The cylinder, the first motor, and the second motor are all controlled by a microcontroller. After a certain period of time, when the amount of material discharged has reached the required level, the first motor is activated, causing the extrusion column to descend and seal the opening of the feed pipe. Simultaneously, the second motor is activated, and its rotation drives the central column and scraper. The scraper removes excess material from the metering tube to ensure filling accuracy. The second motor stops after one revolution, while the first motor, after a short pause, can start running again, increasing its rotational speed so that the extrusion column descends quickly. The descent speed can be controlled to rapidly push out the internal material, increasing the discharge speed. The friction between the extrusion column and the metering tube removes residual material, ensuring filling accuracy.

[0027] In this embodiment, a feed pipe 9 is installed on the metering tube 2. The feed pipe 9 is located below the extrusion column 4 so that the material discharged from the feed pipe can flow out smoothly and enter the metering tube through the positioning tube.

[0028] In this embodiment, a discharge pipe 15 is installed at the end of the housing 1 away from the positioning tube 3. A flexible hose can be connected to the discharge pipe, and the other end of the flexible hose can be placed into the collection box so that the discharged material can be collected and reused later.

[0029] In this embodiment, support frames 13 are installed on both sides of the housing 1.

[0030] The feed pipe is connected to the storage tank through a pipeline and is equipped with a material pump, which allows the material to be injected into the positioning tube along the pipeline and feed pipe and fall into the metering tube. As the material increases, the excess material will overflow from the metering tube. The second motor can drive the rotation of the central column and scraper. The scraper can scrape off the excess material at the top of the metering tube and push it along the shell until it is discharged from the discharge pipe. The discharged material can be recycled and reused, avoiding waste.

[0031] As the second motor starts, the first motor also starts synchronously. The start of the first motor drives the lead screw, and the rotation of the lead screw pushes the extrusion column. As the extrusion column descends, it seals the opening of the feed tube, preventing further feeding. The extension of the piston rod on the cylinder pushes the baffle outward, causing the baffle to move away from the end face of the metering tube. After the baffle opens, the material is quickly discharged through the squeezing of the extrusion column and gravity. The extrusion column also pushes out any residual material on the wall of the metering tube, ensuring filling accuracy.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
