Description

Technical Field

[0001] This invention relates to the field of cosmetic filling technology, and more specifically to a cosmetic direct filling system. Background Technology

[0002] With the rapid development of cosmetics, common cream-based cosmetics generally require processes such as heating, stirring, filling, and cooling to solidify the material. Currently, the common cosmetic filling process typically uses the traditional filling process for creams like lipsticks, where the material is filled and shaped in a silicone mold, then demolded / released, transferred, and assembled into packaging materials. This process is demanding in terms of manufacturing processes, suffers from poor demolding, and has a low yield rate. Furthermore, it requires a high-quality cosmetic formula and also carries the risk of hidden breakage and low efficiency.

[0003] Moreover, most common cosmetic filling devices currently use direct filling from the material tank. The filling volume is affected by the liquid level in the tank, which is also affected by the material pressure. This causes the filling volume to be unstable as the liquid level in the tank changes, resulting in an increased defect rate.

[0004] 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

[0005] The technical problem solved by this invention is to provide a cosmetic direct filling system with high filling efficiency and high yield.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] A cosmetic direct filling system includes a production line for conveying cosmetic packaging materials, a mold for loading the cosmetic packaging materials at a forward tilt, a preheating channel for preheating the cosmetic packaging materials, a secondary storage and filling device for filling the cosmetic packaging materials with cosmetic ingredients, and a baking device for remelting the surface of the cosmetic product after filling; the preheating channel, the secondary storage and filling device, and the baking device are sequentially arranged on the production line to form a preheating station, a filling station, and a baking station.

[0008] Furthermore, the mold includes a mold base and a packaging material mold that is tilted forward on the mold base. The packaging material mold is used to load and place the cosmetic packaging material, and its upper end is regularly provided with a plurality of packaging material positioning grooves for loading and placing the cosmetic packaging material.

[0009] Furthermore, the tilt angle of the packaging mold relative to the horizontal plane is set to 45°~75°.

[0010] Furthermore, the secondary storage and filling device includes:

[0011] 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;

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] A filling nozzle is located at the lower end of the secondary storage module and is connected to the outlet of the valve sleeve.

[0017] 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.

[0018] Furthermore, the secondary storage module is also equipped with a heating module for heating the internal secondary storage chamber and related channels.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] The beneficial effects of this invention are:

[0024] 1. This invention employs a direct filling method from the opening of the cosmetic packaging material. A secondary filling device allows for precise control of the filling volume, followed by a baking device to remelt the cosmetic surface and smooth out any shrinkage pores. This direct-filling process places lower demands on the cosmetic formulation, resulting in more moisturizing products. Furthermore, by adjusting the baking device to control the surface treatment, the defect rate of the product is reduced.

[0025] 2. This 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 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 variations in the liquid level of the cosmetic product in the storage tank during direct filling, thus enabling a direct filling process for cosmetics.

[0026] 3. 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.

[0027] 4. 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 cosmetic material from depositing at the filling nozzle, thus avoiding blockages or leaks. Attached Figure Description

[0044] 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.

[0045] 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.

[0046] like Figure 1-7 As shown, the present invention provides a cosmetic direct filling system, including a production line 1, a preheating channel 2, a mold 3, a secondary material storage and filling device 4, and a baking device 5.

[0047] The preheating channel 2, the secondary storage and filling device 4, and the baking device 5 are sequentially and regularly arranged above the production line 1 to form a preheating station, a filling station, and a baking station. The production line 1 is used to transport the mold 3, and the mold 3 is used to load cosmetic packaging materials.

[0048] The mold 3, which holds the cosmetic packaging material, passes through a preheating station, a filling station, and a baking station in sequence. The cosmetic packaging material loaded on its upper end is preheated through the preheating channel at the preheating station. The cosmetic material is directly filled into the cosmetic packaging material loaded on its upper end through the secondary storage and filling device at the filling station. Finally, the filled cosmetic material is baked and melted into shape by the baking device at the baking station.

[0049] In the direct-fill cosmetic production process, several cosmetic packages are first placed in corresponding molds 3. The packages are then adjusted to ensure their top filling ports are roughly horizontal, achieving alignment. Next, the molds containing the cosmetic packages are placed at the positioning strip or positioning mold at the front of the production line for positioning. The molds 3 carrying the cosmetic packages are conveyed on the production line conveyor belt, passing sequentially through a preheating station, a filling station, and a baking station. At the preheating station, the cosmetic packages are preheated via a preheating channel. Then, at the filling station, a secondary filling device continuously or at specific points fills the cosmetic packages. After filling, the production line continues to convey the molds to the baking station. Upon reaching the baking station, the surface of the cosmetics in the packages has solidified, but the inner layer is not yet fully solidified. Therefore, the baking device at the baking station re-melts the cosmetics in the packages to achieve a more aesthetically pleasing product surface and reduce the defect rate.

[0050] like Figure 1 As shown, production line 1 can be a single production line or multiple production lines joined together end to end.

[0051] The preheating channel 2 is mounted on the supports on both sides of the production line 1 to form a preheating station. The preheating channel includes a preheating cover, and a heating device is installed inside the preheating cover. The heating device includes, but is not limited to, an electric heating device or a lamp heating device.

[0052] Baking device 5 is also placed above production line 1 to form a baking station. The baking device can be a hot air gun or a halogen lamp, etc.

[0053] Furthermore, such as Figure 2The diagram shows the specific structure of mold 3. In this invention, mold 3 includes a mold base 31 and a packaging mold 32 that is tilted forward on the mold base. The packaging mold 32 is used to load and place cosmetic packaging materials, and its upper end is provided with several packaging material positioning grooves for loading and placing cosmetic packaging materials 33. Because the packaging mold 32 is tilted on the mold base 31, when several cosmetic packaging materials are loaded and placed in the packaging material positioning grooves at the upper end of the packaging mold, the cosmetic packaging materials also tilt forward at an angle, thereby facilitating the direct filling and remelting of the cosmetic materials.

[0054] Furthermore, such as Figure 2 As shown, in order to ensure the stability of the mold 3 and the cosmetic packaging materials 33 loaded on its upper end, the mold base 31 adopts a metal or non-metal base with a relatively high density. On the one hand, it can prevent the mold from shifting on the production line, and on the other hand, it can ensure the stability when all cosmetic packaging materials are filled with cosmetic material.

[0055] Furthermore, the packaging mold 32 is inclined at the rear end of the mold base 31 and tilted forward. When several cosmetic packaging materials 33 are loaded and placed in the packaging positioning groove at its upper end, its center of gravity is located in the middle position of the mold, which further improves its stability. The tilt angle is 45°~75° with respect to the horizontal plane.

[0056] like Figure 3-7 The diagram shown is a detailed structural diagram of the secondary storage and filling device of the present invention.

[0057] The secondary storage and filling device includes a storage tank module 41, a feed valve module 42, a secondary storage module 43, a gear pump 44, a three-way valve module 45, and a filling nozzle 46.

[0058] The storage tank module 41 includes a storage tank 411 for storing cosmetic materials and a storage tank stirring motor 412 for stirring the cosmetic materials inside the storage tank. The storage tank stirring motor 412 drives several impellers to rotate inside the storage tank 411 to stir the cosmetic materials inside the storage tank 411, so as to maintain the fluidity and uniformity of the cosmetic materials inside the storage tank 411.

[0059] The feed valve module 42 is located between the storage tank 411 and the secondary storage module 43, and is installed at the discharge port of the storage tank 411. It is used to control the feeding of material from the storage tank 411 into the secondary storage module 43 and to control the feeding amount.

[0060] like Figure 2 and Figure 3As shown, in one embodiment, the feed valve module 42 includes a feed valve body 421, a feed cylinder 422, and a feed piston 423. A valve chamber is provided in the middle of the feed valve body 421. The feed cylinder 422 drives the feed piston 423 to move within the valve chamber. Feed valve inlets 4211 and outlets 4212, respectively, are provided at the front and rear ends of the feed valve body 421, communicating with the valve chamber. To achieve communication between the feed valve inlets 4211 and outlets 4212, a valve feed hole 4231 is provided on the feed piston 423.

[0061] like Figure 3 As shown, the feed cylinder 422 is located at the upper end of the feed valve body 421. Therefore, the valve chamber in the feed valve body is vertically arranged, and the feed piston 423 is vertically installed in the valve chamber of the feed valve body 421, and is sealed to the inner wall of the valve chamber by a sealing ring. Therefore, the valve feed hole 4231 on the feed piston 423 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 421.

[0062] The secondary storage module 43 is used for secondary storage of cosmetic materials, awaiting filling. It includes a secondary storage chamber 431, a secondary storage stirring motor 432, and a liquid level sensor 433. The secondary storage chamber 431 contains a secondary storage cavity 4312 for further storing the cosmetic materials. The secondary storage motor 32 drives several impellers to rotate within the secondary storage cavity 4312 via its front-end shaft to stir the cosmetic materials inside. The liquid level sensor 433 extends into the secondary storage cavity to monitor the liquid level of the cosmetic materials and sends a command to drive the feed valve module 42 to open and inject material into the secondary storage cavity 4312.

[0063] like Figure 3 As shown, the secondary storage chamber 431 has a secondary storage chamber inlet 4311 and a secondary storage chamber outlet 4313 at its front and rear ends, respectively, both of which are connected to the secondary storage chamber 4312 in the middle. The secondary storage chamber 431 is installed at the rear end of the feed valve body 421, with its front inlet 4311 connected to the rear outlet 4212. Thus, the liquid level sensor 433 and the feed valve module 42 control the filling of the storage tank 411 into the secondary storage chamber 4312.

[0064] The gear pump 44 is installed in the outlet 4313 of the secondary storage chamber 431 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 431. The inlet and outlet of the gear pump body are aligned and connected with the outlet 4313 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.

[0065] The three-way valve module 45 is located between the secondary storage chamber 431 and the filling nozzle 46, and is used to control the filling operation of the filling nozzle 46. The three-way valve module 45 includes a three-way valve cylinder 451, a valve shaft 452, and a valve sleeve 453. The three-way valve cylinder 451 drives the valve shaft 452 to rotate within the valve sleeve 453, and the valve shaft 452 and valve sleeve 453 form a three-way valve. The front end and side of the valve shaft 452 are respectively provided with a valve shaft inlet 4521 and a valve shaft outlet 4522, which are interconnected. Figure 3 As shown, the valve shaft inlet and outlet form an L-shaped flow channel.

[0066] like Figure 3 and Figure 5 As shown, the front end of the valve sleeve 453 is provided with a valve shaft groove, and the front end of the valve shaft 452 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 452 extends through the tail end of the valve sleeve 453 and is connected to the shaft of the three-way valve cylinder 451 through an adapter rod assembly. The three-way valve cylinder 451 drives the valve shaft 452 to rotate in the valve shaft groove of the valve sleeve 453 through the adapter rod assembly. The front ends of the valve shaft 452 and the valve sleeve 453 are aligned and set on the same horizontal plane.

[0067] Furthermore, the valve sleeve 453 is provided with a valve sleeve outlet 4531 and a valve sleeve return port 4532 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 4522 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 452 to rotate inside the valve sleeve 453, the connection between the valve shaft outlet 4522 and the valve sleeve outlet 4531 and the valve sleeve return port 4532 can be switched.

[0068] like Figure 3As shown, the filling nozzle 46 is installed at the lower end of the secondary storage chamber 431, and the three-way valve module is installed between the secondary storage chamber 431 and the filling nozzle 46. A valve sleeve mounting groove for installing a valve sleeve 453 is provided between the secondary storage chamber 431 and the filling nozzle 46. The valve sleeve 453 is installed in the valve sleeve mounting groove, with its valve shaft inlet 4521 at its front end communicating with the outlet 4313 of the secondary storage chamber. Its side outlet 4531 is vertically downward and communicates with the filling channel in the filling nozzle 46. When the three-way valve cylinder 451 drives the valve shaft 452 to rotate, rotating the valve shaft outlet 4522 on the side of the valve shaft to the outlet 4531 of the valve sleeve, the outlet 4313 of the secondary storage chamber is connected to the filling channel of the filling nozzle 46, and the filling process begins.

[0069] like Figure 5 As shown, a secondary storage chamber 431 has a secondary storage chamber reflux port 4315 at its rear end. The secondary storage chamber reflux port 4315 is connected to the secondary storage chamber 4312 at its front end. The valve sleeve reflux port 4532 on the side of the valve sleeve 453 is connected to the secondary storage chamber reflux port 4315. 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.

[0070] The three-way valve cylinder 451 drives the valve shaft 452 to rotate within the valve sleeve 453. When the valve shaft outlet 4522 rotates to connect with the valve sleeve outlet 4531, filling begins, thus opening the three-way valve. When the valve shaft outlet 4522 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 44 and the three-way valve flows back to the secondary storage chamber 4312 through the return channel. This design not only effectively achieves precise filling but also prevents the cosmetic material from depositing at the filling nozzle, thus avoiding blockages or leaks.

[0071] like Figure 3 and Figure 5 As shown, to facilitate the cleaning and maintenance of the channels in the secondary storage chamber 431, a discharge port 4314 is opened 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 4315 of the secondary storage chamber is also designed to be open and sealed with a plug.

[0072] Furthermore, to ensure the flowability of the cosmetic material between the secondary storage chamber 431 and the filling nozzle, a heating device is also installed on the secondary storage chamber 431. For example... Figure 3As shown, a heating device mounting groove 434 is provided on the secondary storage cavity 431. The heating device is installed in the heating device mounting groove 434 and sealed in the secondary storage cavity 431 by a partition 4341.

[0073] In one embodiment, the heating device uses a heating rod to uniformly heat the secondary storage cavity 431, thereby uniformly heating the secondary storage cavity, inlet channel, outlet channel, return channel and filling nozzle 46 inside, and preventing the cosmetic material from depositing inside.

[0074] Of course, fluid heating can also be used. Heating pipes can be reasonably set in the secondary storage cavity 431. 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.

[0075] A heating rod is preferred as the heating device for the secondary storage cavity of the present invention.

[0076] Furthermore, such as Figure 1 As shown, the storage tank module 41 is flexibly mounted on the work frame 48 via a slide table 47. The height of the storage tank module on the work frame is adjusted via the slide table, thereby adjusting the height during filling.

[0077] All of the above-mentioned inlets and outlets form corresponding flow channels, passages, or pipeline structures in their respective components.

[0078] 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.

[0079] 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.
