Description

Technical Field

[0001] This invention relates to the field of cosmetic filling technology, specifically to a powder tray and filling device for wet powder filling. Background Technology

[0002] Currently, wet powder filling generally uses direct filling, where wet powder is directly poured into a powder tray through a filling nozzle. After drying, pressing, and cooling, powder blocks / cakes are formed in the tray. However, existing wet powder production processes typically only produce single-color powder blocks / cakes, or powder blocks / cakes with only one function, from the same powder tray.

[0003] In some processes, the powder tray is redesigned with baffles or partitions to divide the tray's chamber into several independent filling zones. Different colors of wet powder can then be filled into these separate zones, allowing different colors of wet powder to be contained within the same tray. However, in this process, the baffles or partitions in the tray cannot be removed; the powder in each filling zone is separated from the others by these baffles or partitions.

[0004] Furthermore, existing wet powder production processes require the addition of a large amount of solvent to smoothly fill the wet powder into the powder tray. After filling, due to the large amount of solvent, the wet powder in the powder tray container is in a liquid state. Therefore, in order to remove excess solvent, the wet powder needs to undergo a long drying process.

[0005] Furthermore, we found that the existing wet powder production process results in insufficient adhesion between the produced wet powder and the powder tray container. Summary of the Invention

[0006] The technical problem solved by the present invention is to provide a powder tray and filling device for wet powder that can produce multiple colors or multiple functions.

[0007] The technical solution adopted by this invention to solve its technical problem is: A powder tray for wet powder filling includes an outer tray, an inner tray, and dividers; The outer disc includes a bottom plate and an outer railing that surrounds the bottom plate and extends upward, with a filling area for filling wet powder material formed between the bottom plate and the railing. The inner disc is arranged along the shape of the outer disc base plate, installed and fixed on the upper end of the outer disc base plate, and completely covers the upper end of the outer disc base plate. The inner disc serves as the upper base plate of the filling area, and the outer disc base plate serves as the lower base plate of the filling area. The inner disc and the outer disc base plate form a double-layer structure. The upper end of the inner disc is regularly provided with a partition slot for the partition to be engaged. The partition is engaged with the upper end of the inner plate through the partition slot, and separates the filling area into several independent filling areas. The inner disk is regularly provided with a number of tapered holes that penetrate the upper and lower ends of the inner disk. The tapered holes are tapered holes that are narrower at the top and wider at the bottom. The number of tapered holes are regularly distributed in the number of independent filling areas. The outer plate and the inner plate are provided with a plurality of filling holes penetrating the inner plate and the outer plate. The plurality of filling holes are regularly distributed in the plurality of independent filling areas. The wet powder filling device fills the plurality of independent filling areas with wet powder of different colors through the corresponding filling holes.

[0008] Furthermore, the inner disc extends downward at its edge to form a downwardly protruding lower inner disc fence, which separates the inner disc from the outer disc bottom plate, forming a micro gap between them. The filling area communicates with the micro gap through the plurality of conical holes. The lower end of the inner disc is regularly provided with a downwardly protruding lower fence of the second filling area along the shape and position of the partition. The lower fence of the second filling area isolates the micro gaps and forms several independent micro gaps with respect to the several independent filling areas.

[0009] Furthermore, the outer plate is regularly provided with positioning points to facilitate the positioning of the inner plate and prevent its misalignment. The inner plate is regularly provided with positioning slots at the positions of the positioning points, and the inner plate is quickly positioned and assembled on the upper end of the outer plate through the positioning slots and positioning points.

[0010] Furthermore, the filling orifice includes a filling hole on the outer plate and a filling port on the inner plate. The filling hole penetrates the upper and lower ends of the outer plate. The filling port includes a downwardly protruding boss and a through hole penetrating the boss. The boss is arranged along the shape of the filling hole and extends into the filling hole on the outer plate, fitting against its inner wall, thereby forming the filling orifice together with the filling hole for filling the wet powder material into the filling area.

[0011] Furthermore, the partition is a patterned partition, including one or more sub-partitions, with a patterned filling area formed on the inner side of the sub-partitions.

[0012] A filling device for wet powder filling includes the powder tray, filling mold and water-absorbing mold described above; The upper end of the filling mold is regularly provided with a powder tray mounting groove for loading the powder tray. Its side panel is regularly provided with several external filling interfaces for easy pipe connection. Its interior is regularly provided with several filling channels to facilitate the flow of the wet powder. The powder tray mounting groove has several internal filling interfaces regularly provided at the positions of the several filling holes to facilitate the outflow of the wet powder. The external filling interfaces are regularly connected to the internal filling interfaces through the filling channels. The external filling interfaces are connected to a material container containing the wet powder through a pipe. The material container sequentially conveys the wet powder into the filling mold through the pipe and the external filling interfaces. The wet powder is sequentially filled into the powder tray through the filling channels, the internal filling interfaces, and the filling holes on the powder tray. The water-absorbing mold presses against the upper end of the powder tray and completely covers the filling area at the upper end of the powder tray, sealing the filling area; the lower end of the water-absorbing mold has a number of tiny water-absorbing micro-holes regularly arranged at the filling area of ​​the powder tray, and a vacuum chamber is arranged inside it. Vacuum interfaces are regularly arranged on its side plate, and the number of water-absorbing micro-holes connect the vacuum chamber and the filling area of ​​the powder tray. The water-absorbing mold is connected to the vacuum chamber through the vacuum interface and vacuum pipe. The vacuum chamber evacuates the vacuum cavity inside the water-absorbing mold through the vacuum pipe, forming a vacuum environment in the vacuum cavity. The vacuum cavity removes the solvent from the wet powder material through the plurality of water-absorbing micropores.

[0013] Furthermore, one or more powder tray positioning points are regularly arranged in the powder tray mounting groove, and a powder tray positioning slot is regularly arranged at the lower end of the powder tray at the position of the powder tray positioning point. The powder tray is quickly installed and fixed in the powder tray mounting groove at the upper end of the filling mold by the mutual cooperation of the powder tray positioning slot and the powder tray positioning point.

[0014] Furthermore, a multi-layer nonwoven fabric is provided between the powder tray and the absorbent mold to separate the wet powder and the solvent.

[0015] Furthermore, the lower end of the filling mold and the upper end of the water-absorbing mold are respectively fixed to the machine by connecting plates, and then driven by a power device to press and separate them from each other, thereby realizing the process of pressing and filling and separating and discharging.

[0016] The powder tray of this invention adopts an inner and outer tray structure. The outer tray has a filling area, and the inner tray is fixed to the bottom of the filling area, serving as the upper base plate of the filling area. Simultaneously, the inner tray has partition slots for easy insertion of partitions. The partitions are engaged with the upper end of the inner tray through these slots, dividing the filling area on the outer tray into several independent filling zones. Each filling zone can be filled with wet powder of different colors, thus enabling the filling of multiple colors of wet powder into a single powder tray. After filling, the partitions can be easily removed, and the powder can then be compacted using a powder compactor. This allows for the regular filling of powder blocks / cakes of different colors or patterns into a powder tray without partitions.

[0017] The powder tray of the present invention has patterned dividers, and an independent patterned filling area is formed on the inner side of the divider. By filling different colored wet powders in the patterned filling area, different colored wet powders in a patterned manner can be filled in one powder tray, thereby increasing the texture and aesthetics of the wet powder.

[0018] The powder tray of this invention also has regularly arranged conical holes that are narrower at the top and wider at the bottom, which penetrate the inner tray. The conical holes can enhance the adhesion between the powder and the powder tray container. When the wet powder is filled and pressed, the powder will enter the conical holes of the inner tray, thereby increasing the adhesion between the powder and the powder tray container through the conical holes that are narrower at the top and wider at the bottom.

[0019] In this invention, a very small micro-gap is provided between the inner and outer base plates of the powder tray. Furthermore, a second lower guardrail for the filling area is regularly provided at the lower end of the inner tray, in a shape and position consistent with the partition, to separate the micro-gap. This second lower guardrail isolates the micro-gap, creating several independent micro-gap areas at the upper end of the inner tray. This effectively prevents wet powder from flowing into the micro-gap through the conical holes of the inner tray during filling, thus avoiding mixing of different materials.

[0020] The filling device of this invention includes a filling mold, a powder tray, and a water-absorbing mold, with multiple layers of non-woven fabric disposed between the powder tray and the water-absorbing mold. The lower end of the water-absorbing mold has a plurality of tiny water-absorbing micropores regularly arranged in the filling area of ​​the powder tray, and a vacuum chamber is provided inside it. Vacuum interfaces are regularly arranged on its side plate. The water-absorbing mold is connected to a vacuum chamber through the vacuum interfaces and vacuum pipes, thereby using the vacuum chamber and vacuum pipes to evacuate the vacuum chamber inside the water-absorbing mold, creating a vacuum environment within the vacuum chamber. Excess solvent in the wet powder is then removed using the vacuum and the tiny water-absorbing micropores, thereby improving the adhesion of the powder. Attached Figure Description

[0022] 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.

[0023] 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.

[0024] like Figures 1-5 As shown, the present invention provides a powder tray for wet powder filling, including an outer tray 11, an inner tray 12, and partitions 13. The outer tray 11 includes a bottom plate 111 and an outer railing 112 surrounding the bottom plate and extending upwards, forming a filling area / chamber for filling wet powder. The inner tray 12 is arranged along the shape of the bottom plate 111, installed and fixed to the upper end of the bottom plate 111, and completely covers the upper end of the bottom plate 111. The inner tray 12 serves as the upper bottom plate of the filling area, and the outer tray bottom plate 111 serves as the lower bottom plate of the filling area, forming a double-layer structure. The partitions 13 are engaged with the upper end of the inner tray 12, separating the filling areas inside the outer tray into several independent filling areas.

[0025] Among them, such as Figure 3 As shown, after the partition 13 and the inner plate 12 are assembled, in one embodiment, a first filling area 1301 is formed outside the partition 13, and a plurality of second filling areas 1302 are formed inside the partition 13. The plurality of second filling areas 1302 are independent of each other by the partition 13. The first filling area 1301 and the plurality of independent second filling areas 1302 are respectively connected to the outside through a plurality of small holes (filling holes) regularly arranged on the bottom plates of the inner plate and the outer plate, so that different materials are filled into each filling area through the plurality of small holes.

[0026] Furthermore, several second filling zones 1302 independently form patterns.

[0027] Furthermore, such as Figure 1As shown, the outer chassis base plate 111 is regularly provided with positioning points 113 for positioning the inner chassis 12 and preventing misalignment. Correspondingly, the inner chassis 12 is regularly provided with positioning slots 121 that cooperate with the positioning points 113. The inner chassis 12 is quickly positioned and assembled onto the upper end of the outer chassis base plate 111 by cooperating with the positioning points 113 on the outer chassis base plate through the positioning slots 121. Then, it is fixed to the upper end of the outer chassis base plate by adhesive, ultrasonic welding, and fasteners, or it can be fixed to the upper end of the outer chassis base plate by a reasonable snap-fit ​​structure.

[0028] Furthermore, such as Figure 1 As shown, the upper end of the inner plate 12 is regularly provided with a partition slot 122 for the partition 13 to be engaged. The partition slot 122 is arranged along the shape of the partition 13, so as to facilitate the partition 13 to be engaged in the upper end of the inner plate 12.

[0029] Furthermore, such as Figure 1 and Figure 2 As shown, the outer plate 111 has one or more first filling holes 1101 regularly arranged in the first filling area 1301, and one or more second filling holes 1102 regularly arranged in the second filling area 1302. Correspondingly, on the inner plate 12 at the positions of the first filling hole 1101 and the second filling hole 1102, there are a number of first filling ports 1201 and a number of second filling ports 1202 regularly arranged.

[0030] Both the first filling port 1201 and the second filling port 1202 include a boss and a through hole penetrating the boss. For example... Figure 2 As shown, the bosses of the first and second filling ports extend into the first and second filling holes, respectively, with their outer surfaces fitting or press-fitting against the inner walls of the filling holes. Through holes penetrating the bosses connect the first and second filling holes to the first and second filling areas, respectively, thereby allowing wet powder to be sequentially filled into the filling areas through the filling holes on the outer plate and the filling ports on the inner plate.

[0031] Furthermore, such as Figure 1 and Figure 5 As shown, the inner disk 12 has several tapered holes 123 regularly arranged on it. The tapered holes 123 penetrate the upper and lower ends of the inner disk 12, with a smaller diameter at the upper end and a larger diameter at the lower end, thus forming a gradually expanding tapered hole at both ends. The tapered holes 123 enhance the adhesion between the powder block and the powder disk container. During filling and pressing, the wet powder enters the tapered holes of the inner disk, and the tapered holes, being narrower at the top and wider at the bottom, increase the adhesion between the powder block and the powder disk container.

[0032] Preferably, in one embodiment, the tapered holes 123 are arranged in an array on the inner disk 12, and a plurality of tapered holes are provided in each filling area.

[0033] Furthermore, such as Figure 2 and Figure 5 As shown, the inner disc 12 extends downwards at its edge to form a downwardly protruding lower inner disc guard 124. The lower inner disc guard 124 separates the inner disc 12 from the outer disc base plate 111, forming a very small micro-gap 14 between them. In this way, wet powder will further flow from the conical hole 123 into the micro-gap 14 and adhere to each other in the micro-gap 14, thereby further strengthening the adhesion between the powder and the powder disc container.

[0034] Furthermore, to prevent the material from flowing from the first filling zone 1301 and several second filling zones 1302 into the micro-gap 14 through the conical hole 123 during the filling process, and mixing in the micro-gap 14, or flowing into different filling zones through the micro-gap 14 and the conical hole, causing mixing between different materials, a downwardly extending protruding lower fence 125 for the second filling zone is regularly provided at the lower end of the inner disc 12 along the shape of the partition 13. The lower fence 125 of the second filling zone isolates the micro-gap 14 independently, forming several independent micro-gap between the first filling zone and several second filling zones. This effectively prevents the wet powder material from flowing into the micro-gap 14 through the conical hole of the inner disc during filling, thus avoiding mixing between different materials.

[0035] Furthermore, the upper end of the partition 13 extends above the upper end of the outer disc enclosure 112. After the wet powder is filled, the partition 13 can be safely removed through the extended part at the top, and then the wet powder in the outer disc can be compacted by the powder press to form powder blocks / cakes. In this way, wet powder of different colors / patterns can be regularly filled into a powder tray container.

[0036] The above-mentioned partitions are single partitions, such as... Figure 3 As shown, in one embodiment, a partition 13 is provided on the inner tray 12. In this embodiment, a single partition 13 includes a plurality of arrayed sub-partitions 131, which are independent of each other, forming an independent second filling area in each sub-partition 131. Therefore, different colored patterns can be filled into a powder tray container through a single partition 13.

[0037] Therefore, in another embodiment, the inner plate 12 may be provided with a plurality of partitions 13, so that a powder tray container can be filled with an array of different colors.

[0038] like Figure 6-10 As shown, the present invention also provides a filling apparatus for wet powder filling, comprising as follows: Figure 1-5The powder tray 1, filling mold 2, and absorbent mold 3 are shown. The powder tray 1 is mounted on the upper end of the filling mold 2, and the absorbent mold 3 is pressed on the upper end of the powder tray 1, completely covering the filling area at the upper end of the powder tray and sealing the filling area at the upper end of the powder tray, thereby preventing the wet powder from overflowing during the filling process.

[0039] Furthermore, such as Figure 7 and Figure 9 As shown, the upper end of the filling mold 2 is regularly provided with a powder tray mounting groove 201 for loading the powder tray 1. Several external filling interfaces 202 are regularly provided on the side plate of the filling mold 2, and several filling channels 204 are regularly provided inside the filling mold 2. The external filling interfaces 202 guide the powder into the powder tray mounting groove 201 through the several filling channels 204, forming several upwardly protruding internal filling interfaces 203 in the powder tray mounting groove 201. The internal filling interfaces 203 are used to extend into the filling holes 102 on the powder tray 1, and the outer surface of the internal filling interfaces 203 is in contact with the inner wall of the filling holes 102 on the powder tray. The external filling interfaces 201 are connected to the material bucket through a pipe. The wet powder in the material bucket flows sequentially through the pipe, the external filling interfaces 201, the filling channels 204, and the filling holes 102 on the powder tray into the filling area 103 of the powder tray, thereby realizing the filling of the wet powder.

[0040] Furthermore, several filling channels 204 are set according to actual needs. Filling areas of the same color share the same external filling interface 202 and filling channel 204. Then, after diversion processing, they are diverted to different filling areas to form several internal filling interfaces 203.

[0041] Furthermore, such as Figure 7 As shown, the lower end of the outer plate of the powder tray 1 is regularly provided with several powder tray positioning slots 101 for positioning the powder tray and preventing it from moving or misaligning. Correspondingly, the powder tray mounting groove 201 at the upper end of the filling mold 2 has several cooperating powder tray positioning points 2011 regularly provided at the positions of the powder tray positioning slots 101. The powder tray 1 is quickly installed and fixed in the powder tray mounting groove 201 at the upper end of the filling mold 2 through the cooperation of the powder tray positioning slots 101 and the powder tray positioning points 2011.

[0042] Furthermore, such as Figure 9 and Figure 10As shown, the lower end of the absorbent mold 3 has several small absorbent micropores 302 regularly arranged in the powder filling area. A vacuum chamber 301 is provided inside the absorbent mold 3, and vacuum interfaces 303 are regularly arranged on the side plate of the absorbent mold 3. The absorbent mold 3 is connected to a vacuum chamber through the vacuum interfaces 303 and vacuum pipes, thereby using the vacuum chamber and vacuum pipes to evacuate the vacuum chamber 301 inside the absorbent mold, creating a vacuum environment within the vacuum chamber 301. Then, the vacuum and the numerous small absorbent micropores 302 are used to remove excess solvent from the wet powder, thereby improving the adhesion of the powder.

[0043] Furthermore, during the use of the filling device of the present invention, multiple layers of non-woven fabric are placed between the powder tray 1 and the absorbent mold 3. Through the multiple layers of non-woven fabric, the wet powder and solvent can be separated during filling. The solvent passes through the multiple layers of non-woven fabric and enters a plurality of absorbent micropores 302 at the lower end of the absorbent mold 3, and is then drawn away through the vacuum chamber 301.

[0044] Furthermore, such as Figure 6 As shown, the lower end of the filling mold 2 and the upper end of the water-absorbing mold 3 are respectively fixed to the corresponding machines by the connecting plate 4, and then driven by the power device to press and separate them, thereby realizing the process of pressing and filling and separating and discharging.

[0045] The shape of the powder tray described above is not limited. In one embodiment, such as... Figure 1 As shown, a circular powder tray can be used. Of course, in other embodiments, powder trays of other shapes can also be used.

[0046] 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.
