Description

Technical Field

[0001] This utility model relates to the field of lipstick production technology, and in particular to a high-efficiency cooling mechanism for lipstick machines. Background Technology

[0002] In the lipstick manufacturing industry, the lipstick forming process in fully automated lipstick machines is a crucial step affecting production efficiency and product quality. Currently, the mainstream fully automated lipstick machine lipstick forming structure in the industry typically adopts an integrated design: the mold for carrying the lipstick is integrated into the conveyor line, which is designed as a closed tank structure. The mold slides and moves through the tank via a sliding part at its bottom. The forming core of the mold is a silicone sleeve installed on the sliding part, which extends into the tank. After the lipstick to be formed is injected into the silicone sleeve, the subsequent cooling process is completed in the closed space of the tank. To achieve rapid cooling and forming of the lipstick, a connected cooling system is usually installed in the tank. By continuously supplying cold air to the tank, the heat conduction properties of the silicone sleeve are used to cool and solidify the lipstick inside. At the same time, to reduce the dissipation of cold air during mold transfer, a cover is installed at the top of the conveyor line, allowing the mold to complete the cooling process in a closed space, thereby ensuring cooling efficiency. However, the existing technical solutions have the following obvious drawbacks in practical applications:

[0003] Firstly, because the mold conveyor line needs to meet the time required for the molten paste to cool sufficiently, it must be long enough. This results in the integrated structure of the conveyor line and the cooling system, which directly increases the overall surface area of ​​the equipment. This not only increases the installation space requirements of the equipment but also accelerates the heat exchange loss of the cold air through the equipment shell due to the increased surface area. In addition, the air inlet and outlet of the cooling system are usually located at the beginning and end of the tank, respectively. To achieve the cold air delivery, long-distance pipes are required, which further exacerbates the dissipation of cold air during the transmission process. This results in a longer pre-cooling time before startup, significantly extending the production preparation cycle.

[0004] Secondly, due to the limited design of the air inlet and outlet positions, the distribution of cold air within the tank is prone to gradient differences. Molds closer to the air inlet cool faster, while molds farther from the air inlet may experience reduced cooling due to the attenuation of cold air, making it difficult to ensure consistent cooling of all pastes in mass production. At the same time, long-distance pipeline transportation and large-area equipment structure lead to reduced cold air utilization, requiring the cooling system to operate continuously at high load to compensate for losses, thus increasing energy consumption.

[0005] Third, the existing structure is mainly designed for mass production of lipsticks, and its cooling efficiency depends on the continuous operation of the conveyor line and the long cooling path. However, in the case of small batch orders, due to the inability to form a continuous production rhythm, the matching between the cold air supply of the cooling system and the mold transfer decreases, resulting in a significant reduction in the cooling and molding efficiency of the lipstick, which makes it difficult to meet the high-efficiency requirements of small batch production.

[0006] In summary, the existing fully automated lipstick machine's lipstick forming structure has significant shortcomings in terms of equipment compactness, cooling efficiency, and flexibility for small-batch production, and an improved technical solution is urgently needed to solve these problems.

Detailed Implementation

[0027] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Please see Figure 1-5 In this embodiment of the present invention, a high-efficiency cooling mechanism for a lipstick machine includes a cooling chamber 10, a mold positioning plate 20 docked to the upper end of the cooling chamber 10, and a plurality of paste forming molds 30 docked to the mold positioning plate 20.

[0029] The cooling chamber 10 is equipped with a cold air supply unit 40. The cold air supply unit 40 has an air outlet 41 and an air inlet 42 located inside the cooling chamber 10. The air outlet 41 of the cold air supply unit 40 faces the mold positioning plate 20, so that circulating cold air can be formed inside the cooling chamber 10 and blown toward the mold positioning plate 20 through the cold air supply unit 40.

[0030] Multiple cooling ports 21 corresponding to the paste forming mold 30 are provided on the mold positioning plate 20. The cooling ports 21 are connected to the cooling chamber 10. A step portion 22 is provided inside the cooling port 21. The paste forming mold 30 includes a positioning frame 31 and a silicone sleeve 32. The silicone sleeve 32 is mounted on the positioning frame 31 and is sealed to the inner side of the positioning frame 31. The positioning frame 31 is positioned and connected to the cooling port 21 and is mounted on the step portion 22.

[0031] The cold air supply unit 40 in the cooling chamber 10 forms circulating cold air, and the air outlet 41 faces the mold positioning plate 20, so that the cold air can be blown directly to the paste forming mold 30 positioned at the cooling port 21 of the mold positioning plate 20. The positioning frame 31 of the paste forming mold 30 is mounted on the step 22 of the cooling port 21. The silicone sleeve 32, which is mounted on the positioning frame 31 and is sealed, can receive the injected paste. The circulating cold air acts on the silicone sleeve 32 through the cooling port 21, and uses the thermal conductivity of the silicone sleeve 32 to cool the paste inside. At the same time, the cold air circulates in the cooling chamber 10, continuously providing a cold source for the cooling process.

[0032] This design, featuring an independent cooling chamber 10 and circulating cold air, eliminates the need for long conveyor lines, significantly reducing the overall size of the equipment and lowering the external surface area to minimize cold air dissipation and shorten pre-cooling time. The cold air is directly blown onto the mold and circulates, improving cooling uniformity and efficiency and ensuring the quality of the paste molding. It is suitable for rapid production of small batch orders, providing efficient cooling even during small-batch production, enhancing production flexibility, while the circulation system reduces energy consumption and improves energy efficiency.

[0033] Based on the structural design of the air supply unit 40 and the cooling chamber 10, this technical solution proposes the following specific implementation method:

[0034] Please see Figure 2-3 Based on the above technical solution, this technical solution further proposes that the air supply unit 40 includes a partition 43, a cooler 44, and an air supply unit 45. The partition 43 is fixed inside the cooling chamber 10 and forms an inner cavity with an air outlet 41 and an air inlet 42. The cooler 44 is installed in the inner cavity and connected to the air inlet 42. The air supply unit 45 is connected to the air outlet 41. There are two partitions 43, with their left and right sides respectively connected to the left and right sides of the cooling chamber 10. One of the partitions 43 is connected to one side of the cooling chamber 10. The cooler 44 is connected between the two partitions 43, and the connecting end of the cooler 44 extends out of the cooling chamber 10 along the partition 43 connected to the cooling chamber 10.

[0035] In a further proposed technical solution, the cold air supply unit 40 forms an inner chamber with an air outlet 41 and an air inlet 42 within the cooling chamber 10 through two partitions 43. The cooler 44 is installed in the inner chamber with its connecting end extending outside the cooling chamber 10, and the air supply unit 45 is connected to the air outlet 41. This design makes the generation and supply of cold air more concentrated and efficient. The connection between the two partitions 43 and the cooling chamber 10 enhances the sealing of the inner chamber and reduces cold air leakage. The external connecting end of the cooler 44 facilitates installation and maintenance and avoids interference with the cold air circulation inside the cooling chamber 10. The air supply unit 45 is precisely connected to the air outlet 41, which can enhance the force and stability of the cold air blowing onto the mold positioning plate 20, further improving the cooling uniformity and efficiency. At the same time, the compact structure also helps to miniaturize the equipment and reduce energy consumption.

[0036] Please see Figure 2-3 Based on the above technical solution, this technical solution further proposes that the cooling chamber 10 includes an air guide shroud 11, a bending plate 12, and two side plates 13. The upper and lower ends of the air guide shroud 11 are open structures. The mold positioning plate 20 is sealed and connected to the upper end of the air guide shroud 11. The upper edges of the two side plates 13 are respectively sealed and connected to the left and right edges of the lower end of the air guide shroud 11. Two partitions 43 are mated between the two side plates 13. The bending plate 12 has a rear side 121, a bottom 122 connected to the lower edge of the rear side 121 and extending forward, and a connecting... The front side 123 is connected to the bottom 122 and faces upward; the upper edge of the rear side 121 is sealed to the rear edge of the lower end of the air guide shroud 11, and the left and right edges of the rear side 121 are sealed to the rear edge of the two side plates 13; the left and right edges of the bottom 122 are sealed to the lower edge of the two side plates 13 respectively; the left and right edges of the front side 123 are sealed to the lower edge of the front end of the two side plates 13 respectively, so that an opening is formed between the front side 123 and the air guide shroud 11, and one of the partition plates 43 is sealed to the opening.

[0037] The proposed cooling chamber 10 structure forms a closed space through the sealed connection of the air guide shroud 11, the bending plate 12 and the two side plates 13. The upper end of the air guide shroud 11 is sealed and connected to the mold positioning plate 20. Each part of the bending plate 12 is sealed and connected to the air guide shroud 11 and the side plates 13 respectively. Only the front side 123 and the air guide shroud 11 are reserved with an opening and sealed and connected by the partition plate 43. This design significantly improves the overall sealing of the cooling chamber 10 through the sealed connection of multiple components, effectively reducing the leakage of cold air from the gaps in the chamber and reducing the loss of cooling capacity. The open upper and lower end structure of the air guide shroud 11, together with the sealed mold positioning plate 20, can guide the cold air to flow more concentratedly to the cooling port 21 of the mold positioning plate 20, enhancing the cooling targeting of the paste molding mold 30. At the same time, the modular splicing structure facilitates the disassembly and maintenance of each component, while the sealed docking design of the specific opening and the partition plate 43 provides a stable interface for the integration of the cold air supply unit 40, further ensuring the efficient operation of the circulating cold air system and contributing to the compactness of the equipment structure while improving cooling efficiency.

[0038] Based on the structural design of the mold positioning plate 20 and the paste forming mold 30, this technical solution proposes the following specific implementation method:

[0039] Please see Figure 4-5 This technical solution further proposes that the cooling port 21 has a square structure, and multiple cooling ports 21 are arranged in an array. The stepped portion 22 is a closed-loop structure surrounding the inner side of the cooling port 21, so that the edge of the positioning frame 31 abuts against the stepped portion 22. The inner side of the positioning frame 31 has a flange groove 311, and the upper end of the silicone sleeve 32 has a flange face 321. The silicone sleeve 32 is sealed and connected to the flange groove 311 through the flange face 321, so that the upper end face of the silicone sleeve 32 is flush with the upper end face of the positioning frame 31.

[0040] In the further proposed technical solution, the cooling port 21 adopts a square structure and is arranged in an array. Combined with the closed-loop structure of the stepped part 22, the edge of the positioning frame 31 is stably abutted against the stepped part 22. This not only improves the accuracy and stability of mold positioning and avoids mold displacement during cooling, which affects the molding quality, but also achieves an orderly layout of multiple molds through the array of cooling ports 21, which can cool multiple pastes at the same time and improve cooling efficiency. The flange groove 311 on the inner side of the positioning frame 31 is sealed and connected with the flange face 321 at the upper end of the silicone sleeve 32, and the upper surfaces of the two are flush. This not only enhances the sealing between the silicone sleeve 32 and the positioning frame 31, preventing cold air from escaping from the gaps and ensuring the cooling effect, but also ensures the flatness of the paste during injection and reduces defects in the paste molding. At the same time, this structural design facilitates the quick disassembly and replacement of the silicone sleeve 32, improving the convenience of equipment maintenance.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
