Description

Technical Field

[0001] This utility model relates to the field of lipstick machine technology, and in particular to a single-tube lipstick machine. Background Technology

[0002] In the production process of lipstick, the application of automated production equipment has greatly improved production efficiency and product quality. Currently, the industry mainly uses an automated small linear lipstick machine proposed in invention patent application publication number CN114259120A and a rotary lipstick machine proposed in utility model patent authorization publication number CN208915484U to achieve automated operation. These two types of lipstick machines use a method where the mold moves on a cooling tunnel to cause the lipstick liquid in the mold to solidify and form, completing a key step in lipstick production.

[0003] However, the two lipstick machines mentioned above have significant drawbacks in practical applications. Because the mold moves on the cooling tunnel, a perfect seal between the mold and the tunnel is difficult to achieve, resulting in substantial loss of cool air. Furthermore, the large surface area of ​​the cooling tunnel further accelerates this loss. These problems not only waste energy and increase production costs but may also affect the molding quality of the lipstick due to unstable cooling, leading to a decrease in product yield. Therefore, a new technical solution is urgently needed to effectively address the severe cool air loss problem in existing lipstick machines during the cooling process, thereby improving production efficiency and product quality.

Detailed Implementation

[0033] 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.

[0034] Please see Figure 1-7 In this embodiment of the utility model, a single-tube lipstick machine includes a body 10, on which a mold conveying turntable 20, a lipstick supply device 30, a cooling chamber 40 and a lipstick receiving device 50 are provided. The body 10 is also equipped with a lipstick quantitative injection mechanism 60 connected between the mold conveying turntable 20 and the lipstick supply device 30, a mold transfer and placement mechanism 70 connected between the mold conveying turntable 20 and the cooling chamber 40, and a lipstick removal mechanism 80 connected between the mold conveying turntable 20 and the lipstick receiving device 50.

[0035] The machine body 10 is equipped with a divider drive system 21. The mold conveying turntable 20 is powered by the divider drive system 21. The mold conveying turntable 20 is surrounded by multiple evenly distributed first mold positioning grooves 22 and paste forming molds 90 positioned in the first mold positioning grooves 22. The paste forming molds 90 move stepwise by the drive of the mold conveying turntable 20 so that each paste forming mold 90 sequentially and periodically connects to the paste quantitative injection mechanism 60, the mold transfer and pick-up mechanism 70 and the paste removal mechanism 80.

[0036] The body 10 is equipped with a cooling system (not shown in the figure) that is connected to the cooling chamber 40. The cooling chamber 40 is also provided with multiple second mold positioning slots 41 arranged in an array. The second mold positioning slots 41 are used to position and place the paste forming mold 90, so that the cold air in the cooling chamber 40 cools and solidifies the paste liquid in the paste forming mold 90.

[0037] The ointment metering injection mechanism 60 is used to meterly inject the ointment from the ointment supply device 30 into the ointment forming mold 90; the mold transfer and placement mechanism 70 is used to transfer the ointment forming mold 90 with the ointment formed in the cooling chamber 40 to the mold conveying turntable 20, and to transfer the ointment forming mold 90 with the ointment injected on the mold conveying turntable 20 to the cooling chamber 40; the ointment removal mechanism 80 is used to remove the ointment formed in the ointment forming mold 90 and transfer it to the ointment receiving device 50.

[0038] During operation, the divider drive system 21 on the machine body 10 drives the mold conveying turntable 20 to rotate in a stepwise manner, so that multiple paste forming molds 90 on the turntable move sequentially and periodically to the corresponding workstations. First, the liquid injection mechanism 60 injects the liquid from the liquid supply device 30 into the liquid forming mold 90 located at the corresponding workstation. Then, the mold transfer and placement mechanism 70 moves the liquid forming mold 90, which has been injected with liquid, from the mold conveying turntable 20 to the second mold positioning slot 41 of the cooling chamber 40 for positioning. At the same time, the liquid forming mold 90, which has been cooled and solidified in the cooling chamber 40, is moved back to the first mold positioning slot 22 of the mold conveying turntable 20. The cooling system delivers cold air into the cooling chamber 40 to cool and solidify the liquid in the liquid forming mold 90 in the enclosed space. Finally, when the mold containing the formed liquid moves with the turntable to the workstation corresponding to the liquid removal mechanism 80, the liquid removal mechanism 80 removes the formed liquid from the mold and transfers it to the liquid receiving device 50, completing the forming process of a single tube lipstick. All mechanisms work together to achieve continuous production.

[0039] By setting up an independent cooling chamber 40, the paste molding mold 90 is positioned and placed inside the cooling chamber 40 for closed cooling, avoiding the sealing problem between the mold and the cooling structure during the movement of the mold, greatly reducing the loss of cold air and reducing energy consumption. At the same time, the relatively compact structure of the cooling chamber 40 also reduces the external surface area, further reducing the loss of cold air and improving cooling efficiency and cooling stability. In addition, by adopting a collaborative approach between the mold conveyor turntable 20 and the cooling chamber 40, combined with the bidirectional transfer function of the mold transfer and pick-up mechanism 70, the orderly connection and continuous production of the paste injection, cooling and paste pick-up processes are realized, improving production efficiency.

[0040] Please see Figure 3-5 Based on the above technical solution, a further proposed paste forming mold 90 includes a square plate 91 and a soft rubber sleeve 92 fixed on the square plate 91 and extending downward. The soft rubber sleeve 92 has an upward opening and is used to form the paste after the paste is injected. The soft rubber sleeve 92 can easily remove the paste from it. Its material properties allow it to easily detach from the paste when it is removed by moderate deformation, which greatly reduces the difficulty of removing the paste, avoids damage to the paste, and improves the efficiency of removing the paste and the integrity of the finished product.

[0041] On the mold conveying turntable 20, the first mold positioning groove 22 includes a first square through hole 221 that is opened through the mold conveying turntable 20 and a first support ring 222 formed inside the first square through hole 221. The paste forming mold 90 is mounted on the first support ring 222 after being connected to the first square through hole 221 by the square plate 91.

[0042] On the cooling chamber 40, the second mold positioning groove 41 includes a second square through hole 411 that is opened through the cooling chamber 40 and a second support ring 412 formed inside the second square through hole 411. The paste forming mold 90 is mounted on the second support ring 412 after being connected to the second square through hole 411 by the square plate 91.

[0043] The first mold positioning groove 22 on the mold conveying turntable 20, through the cooperation of the first square through hole 221 and the first support ring 222, and the second mold positioning groove 41 on the cooling chamber 40, through the cooperation of the second square through hole 411 and the second support ring 412, not only achieve stable positioning of the mold during conveying and cooling, preventing displacement from affecting the accuracy of injection, cooling and picking, but also ensure the consistency of mold placement, making the connection between each process smoother. At the same time, the cooperation between the square plate 91 and the square through hole can also reduce the gap between the mold and the positioning groove. Combined with the closed environment of the cooling chamber 40, it further reduces the loss of cold air from the positioning groove, enhances the cooling effect, and improves the overall production stability and product quality of the single tube lipstick machine.

[0044] Please see Figure 2Based on the above technical solution, it is further proposed that an isolation cover 42 be installed on the machine body 10 to cover the cooling chamber 40 and the mold transfer and placement mechanism 70. A window 421 is provided on one side of the isolation cover 42, through which the mold transfer and placement mechanism 70 extends out of the isolation cover 42 to dock with the paste molding mold 90 on the mold conveying turntable 20. The isolation cover 42 can form a relatively enclosed space, isolating the cooling chamber 40 and the mold transfer and placement mechanism 70 from the external environment. This effectively reduces the impact of airflow around the cooling chamber 40 on the cold air inside, further preventing cold air from diffusing outward from the working area of ​​the cooling chamber 40 and the mold transfer and placement mechanism 70. This, combined with the structure of the cooling chamber 40 itself and the mold and positioning groove... In combination, the isolation cover 42 minimizes the loss of cold air, improves cooling efficiency, and reduces energy consumption. At the same time, the isolation cover 42 can prevent external dust and impurities from entering the working area of ​​the cooling chamber 40 and the mold transfer and placement mechanism 70, reducing contamination of the cream forming mold 90 and the cream, and ensuring the hygiene and quality of the product. In addition, the setting of the window 421 ensures that the mold transfer and placement mechanism 70 can properly connect with the mold conveying turntable 20, while also reducing the gas exchange between the isolation space and the outside world, maintaining the stability of the low temperature environment inside the isolation cover 42, and further improving the operational reliability and production quality of the single tube lipstick machine. Preferably, the isolation cover 42 is generally made of transparent material, which makes it easy for operators to observe the forming of the cream in the cooling chamber 40.

[0045] Please see Figure 6-7 Based on the above-mentioned isolation cover 42, in order to ensure the compactness of the structure and to enable the mold transfer and pick-up mechanism 70 to extend out of the isolation cover 42 through the window 421 to dock with the paste forming mold 90 on the mold conveying turntable 20, on the basis of the above technical solution, it is further proposed that the mold transfer and pick-up mechanism 70 includes a first linear guide rail 71 set on both sides of the cooling chamber 40, an X-axis linear module 72 slidably connected to the first linear guide rail 71, a Y-axis linear module 73 installed on one side of the cooling chamber 40 and poweredly connected to the X-axis linear module 72, a lifting mechanism 74 poweredly connected to the front of the X-axis linear module 72, and a mold clamping mechanism 75 poweredly connected to the front of the lifting mechanism 74. The X-axis linear module 72 is slidably mounted above the cooling chamber 40 through the first linear guide rail 71, and the mold clamping mechanism 75 can extend out of the isolation cover 42 along the window 421 through the X-axis linear module 72 and the lifting mechanism 74.

[0046] The proposed X-axis linear module 72 includes a base plate 721, a lifting frame 722 fixed below both ends of the base plate 721 for sliding connection with a first linear guide rail 71, a second linear guide rail 723 fixedly mounted on the base plate 721, a first lead screw seat 724 mounted on the base plate 721 and located at both ends of the second linear guide rail 723, a first lead screw body 725 movably connected to the first lead screw seat 724, a first motor 726 fixed on the base plate 721 and poweredly connected to the first lead screw body 725, and a pushing component 727 slidably connected to the second linear guide rail 723 and threadedly connected to the first lead screw body 725. A lifting mechanism 74 is fixedly mounted in front of the pushing component 727.

[0047] The lifting mechanism 74 includes a vertical plate 741 fixedly installed in front of the pushing component 727, a third linear guide rail 742 vertically installed in front of the vertical plate 741, a second lead screw seat 743 installed in front of the vertical plate 741 and located at both ends of the third linear guide rail 742, a second lead screw body 744 movably connected to the second lead screw seat 743, a second motor 745 fixed in front of the vertical plate 741 and poweredly connected to the second lead screw body 744, and an extension plate 746 slidably connected in front of the third linear guide rail 742 and threadedly connected to the second lead screw body 744. The extension plate 746 extends forward, and the mold clamping mechanism 75 is fixedly installed downward at the front end of the extension plate 746.

[0048] By sliding the X-axis linear module 72 above the cooling chamber 40, and combining it with the first linear guide rail 71 and the Y-axis linear module 73 to achieve horizontal movement adjustment, and with the lifting mechanism 74 and the mold clamping mechanism 75 to achieve vertical lifting and mold gripping, the overall structure is compact and can efficiently utilize the space above and on both sides of the cooling chamber 40, ensuring the overall compactness of the equipment. The X-axis linear module 72 is slidably connected to the first linear guide rail 71 through the lifting frame 722, and works with the second linear guide rail 723, the first lead screw body 725 and the first motor 726 to drive the push component 727 to move precisely. The lifting mechanism 74 is driven by the third linear guide rail. 742, the second lead screw body 744, and the second motor 745 drive the extension plate 746 and the mold clamping mechanism 75 to rise and fall stably. The precise cooperation of each component ensures that the mold clamping mechanism 75 can accurately extend the isolation cover 42 along the window 421 and stably dock with the cream forming mold 90 on the mold conveying turntable 20, realizing the smooth transfer of the mold. At the same time, the extension plate 746 is extended forward so that the mold clamping mechanism 75 can flexibly extend to the required position to meet the stroke requirements of picking up and placing the mold. The modular structure design facilitates installation and maintenance, further improving the reliability and efficiency of the mold transfer and picking process, and ensuring the smooth connection of each process of the single tube lipstick machine.

[0049] The paste receiving device 50 can be a conveyor line or similar mechanism used to transfer the formed paste from the machine body 10. For improved automation, please refer to [link / reference needed]. Figure 5 Based on the above technical solution, it is further proposed that the paste receiving device 50 has a packaging material positioning component 51 and a packaging material body 52 positioned on the packaging material positioning component 51; the paste taking mechanism 80 includes a fixed frame 81 fixedly installed on the machine body 10, a transverse linear module 82 installed on the fixed frame 81, a longitudinal linear module 83 powered on the transverse linear module 82, a flipping power mechanism 84 powered on the longitudinal linear module 83, and a packaging material clamping mechanism 85 powered on the flipping power mechanism 84. The packaging material clamping mechanism 85 is used to clamp the packaging material body 52, and the packaging material body 52 takes out the paste from the paste forming mold 90 by the drive of the paste taking mechanism 80.

[0050] The paste receiving device 50 also includes a rotary power mechanism 53 mounted on the body 10, a packaging material conveying turntable 54 powered by the rotary power mechanism 53, and a packaging material rotator 55 mounted on the side of the body 10 for docking packaging materials. Multiple packaging material positioning components 51 are provided, and the multiple packaging material positioning components 51 are mounted on the packaging material conveying turntable 54 and evenly distributed along the edge of the packaging material conveying turntable 54.

[0051] The lipstick receiving device 50 precisely positions the packaging body 52 via the packaging positioning component 51. In conjunction with the packaging conveying turntable 54 driven by the rotary power mechanism 53, multiple packaging bodies 52 move orderly with the turntable. Combined with the packaging rotator 55, operators can remove the packaged lipstick from the packaging conveying turntable 54 and insert it into the packaging rotator 55. The rotator 55 then rotates the lipstick uniformly, causing it to retract into the packaging, thus completing the entire lipstick production process. In the lipstick removal mechanism 80, the transverse linear module 82 and the longitudinal linear module 83 work together to drive the packaging clamping mechanism 85 to move flexibly. The flipping power mechanism 84 adjusts the angle of the packaging body 52, ensuring precise alignment with the lipstick forming mold 90 and smooth removal of the lipstick. This achieves automated transfer of the lipstick from the mold to the packaging, significantly improving production continuity.

[0052] To facilitate the loading of the lipstick paste from the soft sleeve 92 into the packaging material, this technical solution can employ a lipstick paste demolding mechanism similar to that described in Utility Model Patent Publication No. CN219835312U, which is used in lipstick machines. A liftable vacuum mechanism is installed below the lipstick paste removal mechanism 80 on the mold conveyor turntable 20. When the lipstick forming mold 90 moves to the corresponding position, the vacuum mechanism is raised to align with the lower end of the mold conveyor turntable 20, forming a sealed space. The soft sleeve 92 is then located within this sealed space. Vacuuming expands the soft sleeve 92, allowing the lipstick paste to be easily removed. If necessary, a top support piece is installed above the soft sleeve 92 to assist in lifting the vacuum mechanism and restrict the area above the mold conveyor turntable 20, improving the sealing of the sealed space, effectively preventing damage during lipstick paste removal, and enhancing product integrity.

[0053] Please see Figure 1-2 Based on the above technical solution, it is further proposed that a leveling mechanism 11 acting on the mold conveying turntable 20 is also installed on the machine body 10. After the paste is injected into the paste forming mold 90, it is rotated through the mold conveying turntable 20 to the position of the leveling mechanism 11. The leveling mechanism 11 is used to level the paste. A preheating mechanism 12 acting on the mold conveying turntable 20 is also installed on the machine body 10. After the paste is taken out from the paste forming mold 90, it is rotated through the mold conveying turntable 20 to the position of the preheating mechanism 12. The preheating mechanism 12 is used to heat the paste forming mold 90.

[0054] The leveling mechanism 11, after the lipstick is injected into the lipstick forming mold 90, uses an air duct to level the lipstick, ensuring that the lipstick is evenly distributed within the mold. This prevents unevenness of the lipstick surface from affecting the shape and quality of the lipstick after cooling and solidification, thus improving the appearance precision of the lipstick. The preheating mechanism 12, after the lipstick is removed from the mold, heats the lipstick forming mold 90 on the mold conveyor turntable 20. This removes residual cold air from the mold, restoring it to a suitable temperature for the next injection. This prevents the low temperature of the mold from affecting the initial state of the lipstick, ensuring the stability of the mold during repeated use and extending its service life.

[0055] The above-mentioned lipstick supply device 30 refers to the mixing tank proposed in Utility Model Patent Publication No. CN220045166U, the lipstick quantitative injection mechanism 60 refers to a lipstick filling mechanism for a lipstick machine proposed in Utility Model Patent Publication No. CN219835310U, the leveling mechanism 11 uses air ducts to level the lipstick in the lipstick forming mold 90, and the preheating mechanism 12 refers to a heating device in an automated small linear lipstick machine proposed in Utility Model Patent Publication No. CN114259120A. Therefore, the specific structures of the lipstick supply device 30, the lipstick quantitative injection mechanism 60, the leveling mechanism 11 and the preheating mechanism 12 will not be described in detail in this application.

[0056] 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.
