Description

Technical Field

[0001] This utility model relates to the field of automatic liquid dispensing machine technology, and in particular to a multi-channel quantitative automatic liquid dispensing machine. Background Technology

[0002] The liquid filling machine is a piston-type liquid filling machine that can fill pharmaceutical liquids, liquid foods, lubricating oils, shampoos, hair creams, and other paste / liquid substances. It has the functions of an integrated paste and liquid filling machine.

[0003] Patent document CN215798459U discloses a liquid dispensing mechanism and its liquid dispensing machine, including a base. Two support plates are welded to the top of the base. Three support rods are welded to the top of each of the two support plates. The six support rods are grouped into sets of three, and a support plate is welded between the tops of each set of support rods. A fixing plate is welded between the tops of the two support plates. A fixing through hole is formed at the top of the fixing plate, and a water tank is fixed to the inner wall of the fixing through hole. A fixing pipe is fixedly connected to the bottom of the water tank. A connecting pipe is fixedly connected to the bottom of the fixing pipe. Multiple water outlet pipes are fixedly connected to the bottom of the multiple water outlet pipes, and an electric valve is fixedly connected to the bottom of each of the multiple water outlet pipes. The outlet of the electric valve is fixedly connected to a conical pipe. The storage tank is moved by an electric telescopic rod, reducing the distance between the inside of the storage tank and the conical pipe. This prevents water from being discharged from the conical pipe and colliding with the ground inside the storage tank due to gravity, thus preventing water waste. The base supports the storage tank, increasing the efficiency of the equipment, while the support rod fixes the connecting plate, increasing the structural stability of the equipment. However, in existing multi-channel quantitative automatic liquid dispensing machines, many air bubbles are generated on the surface of the liquid in the dispensing tank during filling. These air bubbles interfere with the accuracy of the liquid level sensor, often causing false triggering and affecting production efficiency. Utility Model Content

[0004] This utility model discloses a multi-channel quantitative automatic liquid dispensing machine, which aims to solve the technical problem that when filling liquids with materials, many air bubbles will be generated on the surface of the liquid in the dispensing tank. These air bubbles will interfere with the accuracy of the liquid level sensor detection, often causing false triggering and affecting production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-channel quantitative automatic liquid dispensing machine includes a dispensing tank. A top cover is fixedly connected to the top of the dispensing tank by a bolt. A liquid level sensor is installed on the top of the top cover. A liquid inlet is installed on the top of the top cover. A sealing cover is rotatably connected to the top of the liquid inlet via a rotating shaft. A dispensing box is located on the bottom side of the dispensing tank. A dispensing pipe is installed on the side of the dispensing box. An injection pipe is threadedly connected to the bottom of the dispensing pipe. A first rotating wheel is located on the side of the dispensing tank. One end of the first rotating wheel penetrates the bottom side of the dispensing tank and is fixedly connected to a stirring rod. A second rotating wheel is connected to the side of the first rotating wheel via a belt drive. An internal threaded rod is fixedly connected to the inner side of the second rotating wheel, and a defoaming frame is threadedly connected to the outer side of the internal threaded rod.

[0007] In a preferred embodiment, a positioning groove is provided on the bottom side of the sealing cover, and a positioning block located at the bottom of the sealing cover is engaged with the inner side of the positioning groove.

[0008] In a preferred embodiment, the top of the dispensing box is provided with a solenoid valve located inside the dispensing tube.

[0009] In a preferred embodiment, a motor is fixedly connected to the bottom side of the separatory tank, and the output shaft of the motor is fixedly connected to one end of the stirring rod. The first and second rotating wheels on the side of the separatory tank are connected by belt drive, and the inner sides of the first and second rotating wheels are respectively provided with a stirring rod and an internal screw. The motor drives the stirring rod to rotate at a uniform speed, and the stirring blades on the side of the stirring rod are in contact with the bottom of the separatory tank to stir the liquid at the bottom of the separatory tank, so as to prevent it from settling at the bottom of the separatory tank and causing uneven concentration during separation and filling.

[0010] In a preferred embodiment, the bottom of the defoaming rack is provided with a cleaning net and a limiting plate, respectively, and the side of the limiting plate is inlaid with ball bearings.

[0011] In a preferred embodiment, the side of the separator is detachably connected to a side cover by bolt two, and the first and second rotating wheels are located inside the side cover.

[0012] In a preferred embodiment, the length of the defoaming rack is less than the width of the inner side of the dispensing tank; a liquid level sensor is installed on the top cover of the dispensing tank, the liquid level sensor is located inside the dispensing tank, and the length of the defoaming rack inside the dispensing tank is less than the width of the inner side of the dispensing tank, so that the defoaming rack can avoid colliding with the bottom of the liquid level sensor when it moves.

[0013] In a preferred embodiment, an inner plate is fixedly connected to the inner side of the top of the dispensing tank. A limiting groove is formed on the inner side of the inner plate, and the inner side of the limiting groove is slidably connected to the side of the limiting plate at the top of the defoaming frame. The outer side of the inner screw is threadedly connected to the defoaming frame with a cleaning net installed at the bottom. The motor drives the stirring rod to rotate, and at the same time, the inner screw drives the cleaning net at the bottom of the defoaming frame to move at a uniform speed. The motor is a stepper motor, which can realize forward and reverse rotation, so that the cleaning net at the bottom of the defoaming frame can be repeatedly driven to move left and right at a uniform speed. This can scrape off the foam generated on the top of the liquid surface in the dispensing tank, avoiding the generation of many bubbles floating on the liquid surface in the dispensing tank. These bubbles can interfere with the accuracy of the liquid level sensor detection, often causing false triggering and affecting production efficiency. The limiting groove on the inner side of the inner plate is slidably connected to the limiting plate at the top of the defoaming frame. When the defoaming frame moves the cleaning net, the limiting plate at the top of the defoaming frame slides inside the limiting groove on the top of the inner plate, which can keep the defoaming frame stable during movement.

[0014] As can be seen from the above, the multi-channel quantitative liquid automatic dispensing machine provided by this utility model has the following technical effects.

[0015] Firstly, the separator is connected to two rotating wheels on the side of the separator via a belt drive. Each wheel has a stirring rod and an internal lead screw on its inner side. The stirring rod rotates at a constant speed, and the stirring blades on its side are in contact with the bottom of the separator, agitating the liquid at the bottom and preventing sedimentation that could lead to uneven concentration during filling. The internal lead screw is threaded to a defoaming frame with a cleaning screen installed at the bottom. A motor drives the stirring rod to rotate, and simultaneously, the internal lead screw moves the cleaning screen at the bottom of the defoaming frame at a constant speed. The motor is a stepper motor, capable of achieving forward and reverse rotation. The reverse motion allows the cleaning mesh at the bottom of the defoaming frame to move left and right at a uniform speed, scraping away the foam generated on the top of the liquid surface in the dispensing tank. This prevents the formation of numerous floating bubbles on the liquid surface, which can interfere with the accuracy of the liquid level sensor, frequently causing false triggering and affecting production efficiency. The limiting groove on the inner side of the inner plate inside the dispensing tank is slidably connected to the limiting plate on the top of the defoaming frame. When the defoaming frame moves the cleaning mesh, the limiting plate on the top of the defoaming frame slides inside the limiting groove on the top of the inner plate, ensuring the defoaming frame remains stable during movement.

[0016] Secondly, by installing a liquid level sensor on the top cover of the separatory tank, with the liquid level sensor located inside the separatory tank, and the length of the defoaming rack inside the separatory tank being less than the width of the inside of the separatory tank, the defoaming rack can avoid colliding with the bottom of the liquid level sensor when it moves.

A sealing cover 6 is rotatably connected to the top of the inlet trough 5 via a rotating shaft. A dispensing box 9 is provided on the bottom side of the dispensing tank 1. A dispensing pipe 10 is installed on the side of the dispensing box 9. An injection pipe 11 is threadedly connected to the bottom of the dispensing pipe 10. A rotating wheel 15 is provided on the side of the dispensing tank 1. One end of the rotating wheel 15 passes through the bottom side of the dispensing tank 1 and is fixedly connected to a stirring rod 18. A rotating wheel 17 is driven to the side of the rotating wheel 15 via a belt 16. An internal threaded rod 26 is fixedly connected to the inner side of the rotating wheel 17. A defoaming frame 20 is threadedly connected to the outer side of the internal threaded rod 26.

[0027] In this embodiment, the first rotating wheel 15 and the second rotating wheel 17 on the side of the dispensing tank 1 are connected by a belt 16. The inner sides of the first rotating wheel 15 and the second rotating wheel 17 are respectively equipped with a stirring rod 18 and an internal lead screw 26. The motor 19 drives the stirring rod 18 to rotate at a constant speed. The stirring blades on the side of the stirring rod 18 are in contact with the bottom of the dispensing tank 1, stirring the liquid at the bottom of the dispensing tank 1 to prevent it from settling at the bottom and causing uneven concentration during dispensing and filling. The external thread of the internal lead screw 26 is connected to a defoaming frame 20 with a cleaning net 21 installed at the bottom. The motor 19 drives the stirring rod 18 to rotate, and simultaneously the internal lead screw 26 drives the cleaning net 21 at the bottom of the defoaming frame 20 to move at a constant speed. The motor 19 is a stepper motor, which can achieve… The forward and reverse rotation allows the cleaning net 21 at the bottom of the defoaming frame 20 to move left and right at a uniform speed, scraping away the foam generated on the top of the liquid surface in the dispensing tank 1. This prevents the material from generating many bubbles floating on the liquid surface in the dispensing tank 1, which can interfere with the accuracy of the liquid level sensor 4 and frequently cause false triggering, affecting production efficiency. The limiting groove 25 on the inner side of the inner plate 24 inside the dispensing tank 1 is slidably connected to the limiting plate 22 on the top of the defoaming frame 20. When the defoaming frame 20 moves the cleaning net 21, the limiting plate 22 on the top of the defoaming frame 20 slides inside the limiting groove 25 on the top of the inner plate 24, which keeps the defoaming frame 20 stable during movement.

The inner sides of the first rotating wheel 15 and the second rotating wheel 17 are respectively provided with a stirring rod 18 and an internal screw 26. The stirring rod 18 can stir the liquid at the bottom of the liquid separator 1 to prevent it from settling at the bottom of the liquid separator 1, which would result in uneven concentration during liquid separation and filling.

A limiting groove 25 is formed on the inner side of the inner plate 24.

[0031] In this embodiment, the inner threaded rod 26 is connected to the defoaming frame 20 with the cleaning net 21 installed at the bottom. This can scrape off the foam generated on the top of the liquid surface in the dispensing tank 1, preventing the material from generating many bubbles floating on the liquid surface in the dispensing tank 1. These bubbles can interfere with the accuracy of the liquid level sensor 4, often causing false triggering and affecting production efficiency. The limiting groove 25 on the inner side of the inner plate 24 provided inside the dispensing tank 1 is slidably connected to the limiting plate 22 on the top of the defoaming frame 20. When the defoaming frame 20 moves the cleaning net 21, the limiting plate 22 on the top of the defoaming frame 20 slides inside the limiting groove 25 on the top of the inner plate 24, which can keep the defoaming frame 20 stable during movement.

[0033] Working Principle: During use, the liquid is poured into the inner side of the separatory tank 1 through the feed trough, and then the sealing cap 6 is rotated to close. The first rotating wheel 15 and the second rotating wheel 17 on the side of the separatory tank 1 are connected by a belt 16. The inner sides of the first rotating wheel 15 and the second rotating wheel 17 are respectively equipped with a stirring rod 18 and an internal screw 26. The motor 19 drives the stirring rod 18 to rotate at a constant speed. The stirring blades on the side of the stirring rod 18 are in contact with the bottom of the separatory tank 1, stirring the liquid at the bottom of the separatory tank 1 to prevent it from settling at the bottom and causing uneven concentration during filling. The external thread of the internal screw 26 is connected to the defoaming frame 20 with a cleaning net 21 installed at the bottom. The motor 19 drives the stirring rod 18 to rotate, and simultaneously the internal screw 26 drives the cleaning net 21 at the bottom of the defoaming frame 20 to move at a constant speed. The motor 19 is a stepper motor, which can achieve forward and reverse rotation, thus repeatedly driving the cleaning net 21 at the bottom of the defoaming frame 20 to move left and right at a constant speed, which can effectively clean the liquid. The foam generated at the top of the liquid surface in the separating tank 1 is scraped off to prevent the material from generating many bubbles floating on the liquid surface. These bubbles can interfere with the accuracy of the liquid level sensor 4, often causing false triggering and affecting production efficiency. The limiting groove 25 on the inner side of the inner plate 24 inside the separating tank 1 is slidably connected to the limiting plate 22 on the top of the defoaming frame 20. When the defoaming frame 20 moves the cleaning net 21, the limiting plate 22 on the top of the defoaming frame 20 slides inside the limiting groove 25 on the top of the inner plate 24, which can keep the defoaming frame 20 stable during movement.

The liquid level sensor 4 is located inside the separating tank 1, and the length of the defoaming frame 20 inside the separating tank 1 is less than the width of the inner side of the separating tank 1, which can prevent the defoaming frame 20 from colliding with the bottom of the liquid level sensor 4 when moving.
