Description

Technical Field

[0001] This utility model belongs to the field of filling equipment technology, specifically a quantitative filling equipment for detergent production. Background Technology

[0002] Detergents are indispensable cleaning products in daily life, widely used in households, industry and commerce. They remove stains, grease and other impurities through chemical action to keep items clean. Detergents are products specially formulated for cleaning through the washing process. The main components are usually composed of surfactants, detergent builders and additives. In the detergent production process, quantitative filling is a key link to ensure product quality and packaging consistency.

[0003] A Chinese patent describes a quantitative filling device for detergent production (authorized public number: CN210942366U). This device includes a base, a protective mechanism, and a shock-absorbing mechanism. The protective mechanism includes two fixed discs connected by a rotating shaft. A limit spring is wound around the outer surface of the rotating shaft, and an elastic sleeve is wound around one side of the spring. The elastic sleeve design provides rust protection for the sliding rod. The narrow slot design facilitates the unfolding of the elastic sleeve as it passes through the slot, allowing it to be fitted onto the sliding rod while simultaneously being rolled flat onto the fixed disc. The buffer pad design reduces vibration during operation, and the rough base plate design increases friction between the base and the work surface, preventing the base from shifting due to vibration. However, this device is prone to generating excessive foam due to fluid impact during filling, or leakage due to insufficient sealing of the filling head, leading to deviations in metering accuracy. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides the following technical solution: a quantitative filling device for detergent production, comprising a mounting plate frame for fixed connection with the filling device frame, a lifting and adjusting mechanism on the mounting plate frame, a mounting base fixedly connected to the lifting and adjusting mechanism, a metering cylinder fixedly connected to one side of the mounting base, the inlet end of the metering cylinder being connected to the outlet end of the storage cylinder via a hose, a flow sensor at the outlet end of the metering cylinder, a filling nozzle tube connected to the outlet end of the metering cylinder, a heating mechanism on the outer wall of the middle part of the filling nozzle tube, a circular baffle fixedly connected to the outer end of the filling nozzle tube, a sealing ring fixedly connected to the lower side wall of the circular baffle, and a defoaming mechanism on the circular baffle. The defoaming mechanism includes an annular tube sleeved outside the filling nozzle tube and located above the circular baffle. A connector tube is connected to one side of the annular tube. A negative pressure machine is connected to the end of the connector tube away from the annular tube through a telescopic flexible hose. The negative pressure machine is fixed on the mounting plate frame. A plurality of suction heads are connected to the lower side wall of the annular tube. The suction heads all penetrate the circular baffle and extend to the end of the filling nozzle tube. An electromagnetic pressure regulating valve is provided on the upper side wall of the circular baffle.

[0005] As a further embodiment of this utility model: the lifting adjustment mechanism includes a stepper motor fixed to the upper wall of the mounting plate frame. The main shaft of the stepper motor passes through the mounting plate frame and is fixedly connected to a vertically arranged lead screw. A nut block is threaded onto the lead screw. Two symmetrically arranged connecting rods are fixedly connected to one side of the nut block. Two slots are opened on the vertical section side wall of the mounting plate frame. The two connecting rods pass through the two slots respectively and are fixedly connected to the mounting base.

[0006] As a further improvement of this utility model, the inner side of the mounting plate frame is fixedly connected with two vertically symmetrically arranged limiting rods, both of which pass through the nut block.

[0007] As a further embodiment of this utility model: the heating mechanism includes a heat insulation cover fixedly sleeved on the outer wall of the filling nozzle tube, an electric heater fixedly connected to the outer wall of the heat insulation cover, and a heating tube sleeved on the outer wall of the filling nozzle tube located in the heat insulation cover, and the electric heater and the heating tube are electrically connected.

[0008] As a further improvement of this utility model, a plurality of the straw heads are arranged at equal intervals around the filling nozzle tube.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, by setting up a lifting adjustment mechanism, a circular baffle and a sealing ring, starts the stepper motor to drive the lead screw to rotate. At this time, the nut block is forced to move, which can drive the mounting base fixed to the connecting rod to rise or fall. The height of the filling nozzle can be adjusted to suit filling bottles of different heights. It can also control the sealing ring on the circular baffle to press against the filling bottle mouth to achieve a sealing effect and prevent leakage.

[0011] 2. This utility model, by setting up a defoaming mechanism, starts the negative pressure machine to generate negative pressure. Since the telescopic hose is connected to the ring pipe through the connector pipe, the suction head can generate negative pressure at the bottle mouth when it draws air, thereby achieving the effect of eliminating air bubbles and ensuring measurement accuracy. After filling, the electromagnetic pressure regulating valve is opened to make the filling bottle connected to the outside world at the same pressure, so that the sealing ring can be separated from the bottle mouth later.

Detailed Implementation

[0014] Please see Figures 1-4This embodiment provides a quantitative filling device for detergent production. This application only relates to a Chinese patent for a quantitative filling device for detergent production, authorized public number: CN210942366U. The improvement in the filling nozzle in that patent is the only relevant improvement. The other components are existing technology for filling equipment and will not be explained in detail here. The device includes a mounting plate 1 for fixed connection to the frame of the filling equipment. The mounting plate 1 can be installed below the liquid storage cylinder of the filling equipment. The mounting plate 1 is equipped with a lifting and adjusting mechanism, and a mounting base 2 is fixedly connected to the lifting and adjusting mechanism. A metering cylinder 3 is fixedly connected to one side of the mounting base 2 for detergent filling. A piston-type metering cylinder is used. The inlet end of the metering cylinder 3 is connected to the outlet end of the storage cylinder through a hose. The outlet end of the metering cylinder 3 is equipped with a flow sensor 4 to accurately monitor the amount of detergent being filled. The outlet end of the metering cylinder 3 is connected to a filling nozzle tube 5. The outer wall of the middle part of the filling nozzle tube 5 is equipped with a heating mechanism. A circular baffle 6 is fixedly connected to the outer end of the filling nozzle tube 5. A sealing ring 7 is fixedly connected to the lower side wall of the circular baffle 6. A defoaming mechanism is provided on the circular baffle 6. When filling detergent, the filling nozzle tube 5 is inserted into the bottle mouth from top to bottom until the sealing ring 7 on the circular baffle 6 is pressed against the bottle mouth to achieve a sealing effect, prevent leakage, and improve the metering accuracy of filling. The defoaming mechanism includes an annular tube 8 sleeved outside the filling nozzle tube 5 and located above the circular baffle 6. A connector tube 9 is connected to one side of the annular tube 8. The end of the connector tube 9 away from the annular tube 8 is connected to a negative pressure unit 11 via a flexible telescopic hose 10. The negative pressure unit 11 is fixed to the mounting plate frame 1. Several suction heads 12 are connected to the lower side wall of the annular tube 8. All suction heads 12 penetrate the circular baffle 6 and extend to the end of the filling nozzle tube 5. An electromagnetic pressure regulating valve 23 is provided on the upper side wall of the circular baffle 6. Valve 23 is connected to the inside of the bottle mouth. When filling the bottle with detergent, the sealing ring 7 is pressed against the bottle mouth to achieve a seal. The negative pressure machine 11 is started to generate negative pressure. Since the telescopic hose 10 is connected to the ring pipe 8 through the connector pipe 9, the suction head 12 can draw air to generate negative pressure at the bottle mouth, thereby eliminating air bubbles and ensuring measurement accuracy. After filling, the electromagnetic pressure regulating valve 23 is opened to make the filling bottle connected to the outside pressure so that the sealing ring 7 can be separated from the bottle mouth later.

[0015] like Figure 1 and Figure 4As shown: The lifting and adjusting mechanism includes a stepper motor 13 fixed to the upper wall of the mounting plate 1. The main shaft of the stepper motor 13 passes through the mounting plate 1 and is fixedly connected to a vertically arranged lead screw 14. A nut block 15 is threaded onto the lead screw 14. Two symmetrically arranged connecting rods 16 are fixedly connected to one side of the nut block 15. Two slots 17 are opened on the vertical section side wall of the mounting plate 1. The two connecting rods 16 pass through the two slots 17 respectively and are fixedly connected to the mounting base 2. When the stepper motor 13 is started, it drives the lead screw 14 to rotate. Since the lead screw 14 is threadedly connected to the nut block 15, the nut block 15 is forced to move, which can drive the mounting base 2 fixed to the connecting rod 16 to rise or fall. The height of the filling nozzle tube 5 can be adjusted to suit filling bottles of different heights. It can also control the sealing ring 7 on the round baffle 6 to press against the filling bottle mouth.

[0016] like Figure 4 As shown: There are two vertically symmetrically arranged limiting rods 18 fixedly connected to the inner side of the mounting plate frame 1. Both limiting rods 18 are set through the nut block 15, so that the nut block 15 maintains a straight up and down displacement.

[0017] like Figure 2 and Figure 3 As shown: The heating mechanism includes a heat insulation cover 19 fixedly sleeved on the outer wall of the filling nozzle tube 5. An electric heater 20 is fixedly connected to the outer wall of the heat insulation cover 19. A heating tube 21 is sleeved on the outer wall of the filling nozzle tube 5 located in the heat insulation cover 19. The electric heater 20 is electrically connected to the heating tube 21. When the electric heater 20 is started to work, it supplies electricity to the heating tube 21 to heat it, which can slightly heat the detergent in the filling nozzle tube 5, thereby preventing condensation due to low temperature and avoiding blockage.

[0018] like Figure 2 As shown: Several straw heads 12 are arranged in a circle with equal spacing around the filling nozzle tube 5, which has a wide absorption range for detergent foam and a good defoaming effect.

[0019] like Figure 1 As shown: A PLC controller 22 is fixedly connected to the mounting bracket 1. The PLC controller 22 is electrically connected to the lifting and adjusting mechanism, the metering cylinder 3, the flow sensor 4, the heating mechanism, and the defoaming mechanism. It is easy to operate and has an external power supply. The circuit involved is existing technology and can be fully implemented by those skilled in the art, so there is no need to elaborate.

[0020] Working principle: When filling detergent, the stepper motor 13 is started, driving the lead screw 14 to rotate. Since the lead screw 14 is threadedly connected to the nut block 15, the nut block 15 is forced to move, which can drive the mounting base 2 fixed to the connecting rod 16 to rise or fall. This can adjust the height of the filling nozzle tube 5 to accommodate bottles of different heights. It can also control the sealing ring 7 on the round baffle 6 to press against the bottle mouth, achieving a sealing effect and preventing leakage. Then, the negative pressure machine 11 is started to generate negative pressure. Since the telescopic hose 10 is connected to the ring tube 8 through the connector tube 9, the suction head 12 can draw air to generate negative pressure at the bottle mouth, thereby eliminating air bubbles and ensuring measurement accuracy. After filling, the electromagnetic pressure regulating valve 23 is opened to make the bottle connected to the outside pressure, so that the sealing ring 7 can be separated from the bottle mouth later.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
