Description

TECHNICAL FIELD

[0001] The utility model relates to lipstick machine technical field especially is connected in cooling system's lipstick machine mould conveying device. BACKGROUND

[0002] In the lipstick production process, paste cooling forming is a crucial link. At present, the conventional lipstick machine operation mode is: first, the liquid paste is accurately injected into the pre-designed mold, then the mold carrying the liquid paste is placed in a special cooling environment, and the mold is taken out after the paste is cooled and solidified to form a solid paste, and finally the shaped paste is firmly installed on the corresponding package material, thereby completing the production of lipstick.

[0003] In the process of paste forming, the existing technology has achieved many results. For example, the utility model patent authorized publication number CN216453833U discloses an automatic small straight line lipstick machine, which organically combines the cooling mechanism with the mold pushing machine group. The cooling mechanism is composed of a cooling tunnel and a cold air supply device, and the cold air supply device is responsible for providing cold air for the cooling tunnel to create a cooling environment. The mold pushing machine group includes a plurality of paste forming molds and four first pushing cylinders, and the plurality of paste forming molds are sequentially arranged in the cooling tunnel, and the four first pushing cylinders are respectively arranged at the corner positions of the cooling tunnel. With the help of the four first pushing cylinders, the paste forming mold is sequentially pushed to realize the circulating pushing action of the paste forming mold in the cooling tunnel, and the circulating use of the mold and the continuous cooling forming of the paste are achieved.

[0004] However, the inventor found that this kind of lipstick machine with a meandering structure cooling tunnel has significant defects.

Specific implementation

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0034] Please refer to Figures 1-9 In the embodiment of the present application, a lipstick mold conveying device connected to a cooling system comprises a base plate 10, a closed-loop conveying channel 20 and a mold pushing machine set 30 are integrated on the base plate 10, a plurality of paste forming molds 40 are slidingly connected on the closed-loop conveying channel 20, the wall surface of the closed-loop conveying channel 20 is provided with a sliding table part 21, the paste forming molds 40 are arranged on the sliding table parts 21 on both sides of the closed-loop conveying channel 20 and can slide along the sliding table parts 21, the mold pushing machine set 30 is used for pushing the paste forming molds 40, so that the paste forming molds 40 move step by step on the closed-loop conveying channel 20; wherein: the closed-loop conveying channel 20 comprises a material taking and placing conveying channel 22 and a cooling conveying channel 23 vertically connected to both ends of the material taking and placing conveying channel 22, the cooling conveying channel 23 has a plurality of straight channels 231 connected in a meandering manner, the side parts of adjacent straight channels 231 are combined, the base plate 10 is provided with a cooling window 11 connected to the lower end of the cooling conveying channel 23, and the cooling window 11 is used for providing cold air to cool the paste forming molds 40 conveyed on the cooling conveying channel 23.

[0035] The lipstick machine mold conveying device is combined with a cooling system and applied to a lipstick machine, such as the automatic small straight-line lipstick machine described in the invention patent application publication No. CN114259120A. In the operation process of the lipstick machine, a plurality of paste forming molds 40 are slidably connected to the slide table parts 21 on both sides of the closed-loop conveying channel 20. The mold pushing unit 30 starts to work and pushes the paste forming molds 40 to move step by step on the closed-loop conveying channel 20. When the paste forming molds 40 enter the material taking and placing conveying channel 22, the paste liquid can be injected into the molds through the paste filling mechanism. Then, the molds continue to move. Since the closed-loop conveying channel 20 is composed of the material taking and placing conveying channel 22 and the cooling conveying channel 23 vertically connected to both ends of the material taking and placing conveying channel 22, the molds enter the cooling conveying channel 23. The cooling conveying channel 23 is composed of a plurality of straight channels 231 connected in a meandering manner. The paste forming molds 40 move along the straight channels 231 in sequence through the pushing of the mold pushing unit 30. At the same time, the cooling window 11 on the base plate 10 provides cooling air to cool the paste forming molds 40 moving on the cooling conveying channel 23, so that the liquid paste in the paste forming molds 40 cools and solidifies. After the paste is cooled, the paste forming molds 40 return to the material taking and placing conveying channel 22 again. At this time, the paste formed in the paste forming molds 40 is taken out through the package clamp paste loading mechanism, and new liquid paste is injected again. The above-mentioned paste filling mechanism and package clamp paste loading mechanism are mechanisms in CN114259120A, and the utility model will not be further described.

Secondly, the cooling window 11 accurately provides cooling air for the cooling conveying channel 23, avoids the ineffective diffusion of cooling air, improves the energy utilization rate, reduces the energy consumption, and thus reduces the production cost of the lipstick. In addition, the closed-loop conveying channel 20 cooperates with the mold pushing unit 30, which mainly utilizes the structure design of the cylinder arranged at the corner position of the traditional meandering structure to push the mold. Although the present technical solution changes the traditional meandering structure to a meandering structure, the mold pushing unit 30 used to push the paste forming molds 40 is essentially the same as the principle of the traditional cylinder pushing the paste forming molds 40. The circulation use of the paste forming molds 40 is realized, the production efficiency of the lipstick machine is improved, and it is conducive to the development of the lipstick production industry in a more efficient and energy-saving direction.

[0040] The above two cooperate to accurately push the paste molding mold 40 at different positions of the closed-loop conveying channel 20, further optimize the mold circulation process, improve the efficiency of the lipstick machine, and the power mode based on the belt transmission mechanism has lower energy consumption than the traditional cylinder direct pushing, which improves the production efficiency while further reducing energy consumption and production cost, and helps the efficient and energy-saving development of the lipstick production industry.

[0041] Please refer to Figure 3 and Figure 4 , on the basis of the above technical solutions, it is further proposed that the second pushing unit 32 and the third pushing unit 33 each have at least two groups of power pushing mechanisms 50 mounted outside the end positions of the straight channel 231, the power pushing mechanisms 50 are each provided with a pushing block 51 combined to the inner wall of the closed-loop conveying channel 20, and the power pushing mechanisms 50 drive the pushing block 51 to abut against the side of the paste molding mold 40 and push the paste molding mold 40;

The paste forming mold 40 adopts the design of the mold main plate 42 matched with the paste profiling silica gel piece 43, and the paste profiling silica gel piece 43 is in abutment with the sliding table part 21, which not only ensures the smoothness of the mold sliding on the sliding table part 21, but also provides a precise profiling space for paste forming, which helps to improve the paste forming quality.
