Secondary storage filling device

Abstract

This invention relates to a secondary storage and filling device, comprising a storage tank module, an inlet valve module, a secondary storage module, a gear pump, a three-way valve, and a filling nozzle. The invention utilizes a secondary storage module at the front end of the storage tank for secondary storage and filling. A sensor is installed within the secondary storage chamber of the secondary storage module to monitor the liquid level of the cosmetic material inside. By monitoring the liquid level in the secondary storage chamber, the liquid level, i.e., the volume of cosmetic material within the secondary storage chamber, can be precisely controlled. This avoids the instability in filling volume caused by fluctuations in the liquid level of the cosmetic material in the storage tank during direct filling. The pressureless gear pump then performs the filling operation, ensuring that the filling volume is unaffected by the liquid level in the storage tank, achieving precise control of the filling volume. This ensures the successful filling of special materials that cannot withstand pressure, reducing the product defect rate.

Description

Technical Field

[0001] This invention relates to the field of cosmetic filling technology, specifically to a secondary storage and filling device. Background Technology

[0002] With the rapid development of cosmetics, common cream cosmetics generally require processes such as heating, stirring, filling, and cooling to solidify the material. Currently, most cosmetic filling devices directly fill from the container, and the filling volume is affected by the liquid level in the container, i.e., the liquid pressure. This causes the filling volume to be unstable as the liquid level in the container changes, resulting in an increased defect rate.

[0003] Furthermore, in existing filling systems, filling nozzles are prone to clogging due to material buildup. A common solution is to modify the nozzle structure by adding a heated flow channel, using a high-temperature fluid to heat the nozzle. While this method can reduce material buildup in the nozzle, it significantly increases the manufacturing complexity. The high-temperature fluid is typically hot water, which can lead to sealing issues and leakage during prolonged use. Summary of the Invention

[0004] The technical problem solved by this invention is to provide a filling device that uses secondary storage, which precisely controls the liquid level in the secondary storage chamber through a sensor, and then uses a pressureless gear pump for filling, thereby reducing the impact of the liquid level of cosmetic material inside the container.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A secondary storage and filling device, comprising:

[0007] A storage tank module, comprising a storage tank for storing cosmetic materials and a storage tank stirring motor for stirring the cosmetic materials inside the storage tank;

[0008] A secondary storage module includes a secondary storage chamber for secondary storage, a secondary storage stirring motor for stirring the cosmetic material inside the secondary storage chamber, and a sensor for monitoring the liquid level of the cosmetic material inside the secondary storage chamber.

[0009] The feed valve module is disposed between the discharge port of the storage tank and the secondary storage module as an on / off valve for the storage tank and the secondary storage module. The feed valve module receives feedback signals from the sensor to open the valve to inject material into the secondary storage chamber.

[0010] A gear pump, the pump body of which is located in the discharge channel of the secondary storage module, drives a pair of meshing gears inside the pump body to rotate to extract the cosmetic material from the secondary storage chamber, thereby achieving pressureless gear filling.

[0011] The three-way valve module includes a three-way valve power unit and a three-way valve. The three-way valve includes a valve shaft and a valve sleeve. The valve shaft is provided with a valve shaft inlet and a valve shaft outlet. The valve sleeve is provided with a valve sleeve outlet and a valve sleeve return outlet. The valve shaft inlet is connected to the outlet channel of the secondary storage module. The three-way valve power unit drives the valve shaft to rotate within the valve sleeve, switching the connection between the valve shaft outlet and the valve sleeve outlet. The valve sleeve return outlet is connected to the secondary storage chamber through the return channel in the secondary storage module.

[0012] A filling nozzle is located at the lower end of the secondary storage module and communicates with the outlet of the valve sleeve.

[0013] Furthermore, the feeding valve module includes a feeding valve body, a feeding cylinder, and a feeding piston. The feeding valve body has a valve chamber in the middle, and the feeding cylinder drives the feeding piston to move within the valve chamber. The front and rear ends of the feeding valve body are respectively provided with a feeding valve inlet and a feeding valve outlet communicating with the valve chamber. The feeding piston is provided with a feeding hole communicating with the feeding valve inlet and the feeding valve outlet. The feeding valve inlet is connected to the outlet of the storage tank, and the feeding valve outlet is connected to the feeding port of the secondary storage module.

[0014] Furthermore, the secondary storage module is equipped with a heating module for heating the internal secondary storage chamber and related channels.

[0015] In one embodiment, preferably, the heating module uses heating rods for heating, and several heating rods are regularly arranged inside the lower end of the secondary storage module and encapsulated in the secondary storage module by a partition.

[0016] In one embodiment, preferably, the heating module uses high-temperature fluid heating, and the secondary storage module has heating pipes arranged in a regular pattern inside. The high-temperature fluid circulates in the heating pipes to achieve the fluidity of the cosmetic material inside the secondary storage module.

[0017] Furthermore, the power unit of the three-way valve is a three-way valve cylinder, which drives the valve shaft to reciprocate within the valve sleeve via an adapter rod assembly.

[0018] Furthermore, the lower end of the secondary storage chamber in the secondary storage module is provided with a discharge port and sealed by a plug, and the front end or side end of the return channel in the secondary storage module is also designed to be open and sealed by a plug.

[0019] Furthermore, the storage bin module is flexibly mounted on the work frame via a slide table, and its height on the work frame is adjusted via the slide table.

[0020] Furthermore, the material storage tank outlet is sealed with sealing rings between itself and the inlet valve module, between the inlet valve module and the secondary storage module, between the secondary storage module and the gear pump, and between the secondary storage module and the three-way valve and the filling nozzle.

[0021] The beneficial effects of this invention are:

[0022] 1. This invention utilizes a secondary storage module at the front end of the storage tank for secondary filling. A sensor is installed within the secondary storage chamber of this module to monitor the liquid level of the cosmetic product. By monitoring the liquid level in the secondary storage chamber, the volume and capacity of the cosmetic product within can be precisely controlled. This avoids the instability in filling volume caused by fluctuations in the liquid level of the cosmetic product when directly filling from the storage tank.

[0023] 2. This invention uses a pressureless gear pump for filling, so the filling volume is not affected by the liquid level in the storage tank, achieving precise control of the filling volume. This ensures the smooth filling of special materials that cannot be pressurized, reduces the product defect rate, and thus improves product consistency and yield.

[0024] 3. This invention uses a three-way valve cylinder to drive the valve shaft to rotate within the valve sleeve. When the valve shaft outlet rotates to connect with the valve sleeve outlet, filling begins, thus opening the three-way valve. When the valve shaft outlet rotates to connect with the valve sleeve return port, the filling process ends, closing the three-way valve. At this time, the return channel is open, and the cosmetic material from the secondary storage chamber outlet at the rear of the gear pump and the three-way valve flows back into the secondary storage chamber through the return channel. This design not only effectively achieves precise filling but also prevents the accumulation of cosmetic material at the filling nozzle, thus avoiding blockages or leaks. Attached Figure Description

[0037] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] like Figure 1-5 As shown, the present invention provides a secondary storage and filling device, including a storage tank module 1, a feeding valve module 2, a secondary storage module 3, a gear pump 4, a three-way valve module 5, and a filling nozzle 6.

[0040] The storage tank module 1 includes a storage tank 11 for storing cosmetic materials and a storage tank stirring motor 12 for stirring the cosmetic materials inside the storage tank. The storage tank stirring motor 12 drives several impellers to rotate inside the storage tank 11 to stir the cosmetic materials inside the storage tank 11, so as to maintain the fluidity and uniformity of the cosmetic materials inside the storage tank 11.

[0041] The feed valve module 2 is located between the storage tank 11 and the secondary storage module 3, and is installed at the discharge port of the storage tank 11. It is used to control the feeding of material from the storage tank 11 into the secondary storage module 3 and to control the feeding amount.

[0042] like Figure 2 and Figure 3 As shown, in one embodiment, the feed valve module 2 includes a feed valve body 21, a feed cylinder 22, and a feed piston 23. A valve chamber is provided in the middle of the feed valve body 21. The feed cylinder 22 drives the feed piston 23 to move within the valve chamber. Feed valve inlets 2101 and outlets 2102, respectively, are provided at the front and rear ends of the feed valve body 21, communicating with the valve chamber. To achieve communication between the feed valve inlets 2101 and outlets 2102, a valve feed hole 2301 is provided on the feed piston 23.

[0043] like Figure 3 As shown, the feed cylinder 22 is located at the upper end of the feed valve body 21. Therefore, the valve chamber in the feed valve body is vertically arranged, and the feed piston 23 is vertically installed in the valve chamber of the feed valve body 21, and is sealed to the inner wall of the valve chamber by a sealing ring. Therefore, the valve feed hole 2301 on the feed piston 23 is horizontally arranged, thereby communicating with the valve feed port and valve discharge port that are horizontally arranged at both ends of the feed valve body 21.

[0044] The secondary storage module 3 is used for secondary storage of cosmetic materials, awaiting filling. It includes a secondary storage chamber 31, a secondary storage stirring motor 32, and a liquid level sensor 33. The secondary storage chamber 31 contains a secondary storage cavity 3102 for further storing the cosmetic materials. The secondary storage motor 32 drives several impellers to rotate within the secondary storage cavity 3102 via its front-end shaft, thus stirring the cosmetic materials within. The liquid level sensor 33 extends into the secondary storage cavity to monitor the liquid level of the cosmetic materials and sends a command to open the feed valve module 2 to inject material into the secondary storage cavity 3102.

[0045] like Figure 3 As shown, the secondary storage chamber 31 has a secondary storage chamber inlet 3101 and a secondary storage chamber outlet 3103 at its front and rear ends, respectively, both of which are connected to the secondary storage chamber 3102 in the middle. The secondary storage chamber 31 is installed at the rear end of the feed valve body 21, with its front inlet 3101 connected to the rear outlet 2102. Thus, the liquid level sensor 33 and the feed valve module 2 control the storage tank 11 to fill the secondary storage chamber 3102.

[0046] The gear pump 4 is installed in the outlet 3103 of the secondary storage chamber 31 to achieve pressureless gear filling of cosmetic materials. A pump mounting groove for the gear pump body is provided in the middle of the outlet flow channel of the secondary storage chamber 31. The inlet and outlet of the gear pump body are aligned and connected with the outlet 3103 of the secondary storage chamber, thereby enabling pressureless gear conveying and filling of the cosmetic materials in the secondary storage chamber through a pair of meshing gears inside the pump body.

[0047] The three-way valve module 5 is located between the secondary storage chamber 31 and the filling nozzle 6, and is used to control the filling operation of the filling nozzle 6. The three-way valve module 5 includes a three-way valve cylinder 51, a valve shaft 52, and a valve sleeve 53. The three-way valve cylinder 51 drives the valve shaft 52 to rotate within the valve sleeve 53, and the valve shaft 52 and valve sleeve 53 form a three-way valve. The front end and side of the valve shaft 52 are respectively provided with a valve shaft inlet 5201 and a valve shaft outlet 5202, which are interconnected. Figure 3 As shown, the valve shaft inlet and outlet form an L-shaped flow channel.

[0048] like Figure 3 and Figure 5As shown, the front end of the valve sleeve 53 is provided with a valve shaft groove. The front end of the valve shaft 52 is installed in the valve shaft groove and rotates along the inner wall of the valve shaft groove. The tail end of the valve shaft 52 extends through the tail end of the valve sleeve 53 and is connected to the rotating shaft of the three-way valve cylinder 51 through an adapter rod assembly. The three-way valve cylinder 51 drives the valve shaft 52 to rotate within the valve shaft groove of the valve sleeve 53 through the adapter rod assembly. The front ends of the valve shaft 52 and the valve sleeve 53 are aligned and positioned on the same horizontal plane.

[0049] Furthermore, the valve sleeve 53 is provided with a valve sleeve outlet 5301 and a valve sleeve return port 5302 on its side. Both the valve sleeve outlet and the valve sleeve return port are connected to the valve shaft rotation groove in the valve sleeve. The positions of the valve sleeve outlet and the valve sleeve return port are aligned with the position of the valve shaft outlet 5202 on the side of the valve shaft, and are designed along the same cross-section. Therefore, when the three-way valve cylinder drives the valve shaft 52 to rotate inside the valve sleeve 53, the connection between the valve shaft outlet 5202 and the valve sleeve outlet 5301 and the valve sleeve return port 5302 can be switched.

[0050] like Figure 3 As shown, the filling nozzle 6 is installed at the lower end of the secondary storage chamber 31, and the three-way valve module is installed between the secondary storage chamber 31 and the filling nozzle 6. A valve sleeve mounting groove for installing a valve sleeve 53 is provided between the secondary storage chamber 31 and the filling nozzle 6. The valve sleeve 53 is installed in the valve sleeve mounting groove, with its valve shaft inlet 5201 at its front end communicating with the outlet 3103 of the secondary storage chamber. Its side outlet 5301 is vertically downward and communicates with the filling channel in the filling nozzle 6. When the three-way valve cylinder 51 drives the valve shaft 52 to rotate, rotating the valve shaft outlet 5202 on the side of the valve shaft to the outlet 5301, the outlet 3103 of the secondary storage chamber is connected to the filling channel of the filling nozzle 6, and the filling process begins.

[0051] like Figure 5 As shown, the secondary storage chamber 31 also has a secondary storage chamber reflux port 3105 at its rear end. The secondary storage chamber reflux port 3105 is connected to the secondary storage chamber 3102 at its front end. The valve sleeve reflux port 5302 on the side of the valve sleeve 53 is connected to the secondary storage chamber reflux port 3105. When the three-way valve module closes the valve on the filling nozzle, the reflux channel will open, thereby effectively preventing the sedimentation of the internal material.

[0052] The three-way valve cylinder 51 drives the valve shaft 52 to rotate within the valve sleeve 53. When the valve shaft outlet 5202 rotates to connect with the valve sleeve outlet 5301, filling begins, thus opening the three-way valve. When the valve shaft outlet 5202 rotates to connect with the valve sleeve return port, the filling operation ends, closing the three-way valve. At this time, the return channel is open, and the cosmetic material from the secondary storage chamber outlet at the rear of the gear pump 4 and the three-way valve flows back to the secondary storage chamber 3102 through the return channel. This design not only effectively achieves precise filling but also prevents the accumulation of cosmetic material at the filling nozzle, thus avoiding blockages or leaks.

[0053] like Figure 3 and Figure 5 As shown, to facilitate the cleaning and maintenance of the channels in the secondary storage chamber 31, a discharge port 3104 is provided at the lower end of the secondary storage chamber 31 and sealed with a plug. The front end or side end of the return port 3105 of the secondary storage chamber is also designed to be open and sealed with a plug.

[0054] Furthermore, to ensure the flowability of the cosmetic material between the secondary storage chamber 31 and the filling nozzle, a heating device is also installed on the secondary storage chamber 31. For example... Figure 3 As shown, a heating device mounting groove 34 is provided on the secondary storage cavity 31. The heating device is installed in the heating device mounting groove 34 and sealed in the secondary storage cavity 31 by a partition 3401.

[0055] In one embodiment, the heating device uses a heating rod to uniformly heat the secondary storage cavity 31, thereby uniformly heating the secondary storage cavity, inlet channel, outlet channel, return channel and filling nozzle 6 inside, and preventing the cosmetic material from depositing inside.

[0056] Of course, fluid heating can also be used. Heating pipes can be reasonably set in the secondary storage cavity 31. By adding high-temperature fluid to the heating pipes of the secondary storage cavity, uniform heating treatment can be achieved on its interior and filling nozzle.

[0057] A heating rod is preferred as the heating device for the secondary storage cavity of the present invention.

[0058] Furthermore, such as Figure 1 As shown, the storage tank module 1 is flexibly mounted on the work frame 8 via the slide table 7. The height of the storage tank module on the work frame is adjusted by the slide table, thereby adjusting the height during filling.

[0059] All of the above-mentioned inlets and outlets form corresponding flow channels, passages, or pipeline structures in their respective components.

[0060] The aforementioned feed cylinder and three-way valve cylinder are both power devices. In other embodiments, a power device such as an electric motor can also be used to drive them.

[0061] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
