Description

Technical Field

[0001] This utility model relates to the field of lipstick production technology, and in particular to a PPU-type lipstick filling mechanism for use in lipstick machines. Background Technology

[0002] In the lipstick manufacturing industry, with the increasing demand for automation, various lipstick machines have emerged. Their core purpose is to achieve highly efficient automation of the lipstick production process, thereby improving production efficiency and reducing labor costs. Currently, the common workflow of a lipstick machine is as follows: first, the mold used to form the lipstick paste is placed in a cooling chamber for cooling. After the paste has cooled and solidified, it is removed from the mold and transferred to a rotatable packaging material, ultimately producing the lipstick product. For example, a fully automatic multi-station paste-filling mechanism disclosed in utility model patent announcement number CN220865828U innovatively uses a method where the packaging material moves downwards along the top of the paste-forming mold, precisely fitting the bottom of the paste onto the packaging material. Then, through an upward motion, the paste and packaging material are removed together, successfully completing the lipstick manufacturing process.

[0003] However, existing technologies typically require the setup of Z-axis and Y-axis conveyor lines. These two conveyor lines rely on two independent power sources, and in actual operation, precise and synchronized control of these two power sources is necessary to ensure the stable transport of packaging materials along the preset path. This undoubtedly increases the energy consumption of the equipment significantly. Furthermore, the coordinated control of dual power sources places high demands on the complexity of the programming settings.

[0004] In summary, existing lipstick production technologies suffer from high energy consumption and complex process control in the lipstick encapsulation stage, urgently requiring an innovative technological solution to improve them and meet the lipstick manufacturing industry's demand for efficient, energy-saving, and precise automated production.

[0026] 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.

[0027] Please see Figure 1-5 In this embodiment of the present invention, a PPU-type lipstick filling mechanism for a lipstick machine includes a base plate 10. A demolding unit 20, a packaging material supply unit 30, and a PPU flipping and clamping unit 40 are mounted on the base plate 10. The PPU flipping and clamping unit 40 includes a fixing frame 41 mounted on the base plate 10, a PPU robotic arm 42 mounted on the fixing frame 41, and a flipping and clamping mechanism 43 powered by the PPU robotic arm 42.

[0028] The demolding unit 20 is used to receive the paste forming mold 1 at a fixed point and to initially separate the paste and the mold inside the paste forming mold 1; the packaging material supply unit 30 is used to supply the packaging material 2 with the opening facing upward at a fixed point;

[0029] The flipping clamping mechanism 43 has a 180-degree flipping mechanism 44 and a power gripper 45 powered to the 180-degree flipping mechanism 44. The power gripper 45 is used to grip the packaging material 2 and flip the packaging material 2 180 degrees through the 180-degree flipping mechanism 44. The PPU robot arm 42 is used to drive the gripped packaging material 2 to the demolding unit 20 to insert the paste, and also to drive the packaging material 2 after inserting the paste to the packaging material supply unit 30.

[0030] In the above technical solution, the PPU-type lipstick filling mechanism is applied in a lipstick machine, involving the operation of removing the cooled and formed lipstick from the mold onto the packaging material 2. This is achieved by setting up a demolding unit 20, a packaging material supply unit 30, and a PPU flipping and clamping unit 40. The demolding unit 20 is used to receive the lipstick forming mold 1 at a fixed point and to initially separate the lipstick from the mold within the mold. The packaging material supply unit 30 is used to supply the packaging material 2 with its opening facing upwards at a fixed point. Specifically, the demolding unit 20 includes a lifting mechanism 21 installed at the lower end of the base plate 10, and a power connection to... The lifting mechanism 21 is capable of lifting the vacuum chamber 22 onto the base plate 10, and the top abutment frame 23 is mounted on the base plate 10. A mold conveying line 11 is provided between the top abutment frame 23 and the vacuum chamber 22. The mold conveying line 11 is used to provide a silicone paste molding mold 1 between the vacuum chamber 22 and the top abutment frame 23. The vacuum chamber 22 seals the paste molding mold 1 against the top abutment frame 23 by the lifting mechanism 21, and the top abutment frame 23 has an opening for docking with the paste molding mold 1. As shown in the figure, a turntable mechanism is used to transport the mold. After the cream cools and solidifies, the turntable mechanism transports the mold to the demolding unit 20. When the vacuum chamber 22 is driven by the lifting mechanism 21 to lift the cream forming mold 1 to the top abutment frame 23, a closed space is formed between the cream forming mold 1 and the vacuum chamber 22. More specifically, refer to the cream demolding mechanism for lipstick machines described in the utility model patent authorization announcement number CN219835312U. Therefore, the vacuuming step of the cream forming mold 1 will not be described in detail in this technical solution. The packaging material supply unit 30 includes a turntable transfer mechanism 31 and multiple packaging material positioning fixtures 32 evenly installed on the turntable transfer mechanism 31. After the packaging material 2 is placed on the packaging material positioning fixture 32 with its opening facing upward, it is transferred to the position of the PPU flipping clamping unit 40 by the turntable transfer mechanism 31. After being clamped by the power gripper 45, it is flipped 180 degrees and transferred to the position of the paste forming mold 1 at the demolding unit 20. The paste in the paste forming mold 1 is fixed to the packaging material 2 by inserting the packaging material 2. Then, the paste forming mold 1 is separated from the paste by vacuuming the vacuum chamber 22, so that the paste fixed on the packaging material 2 can be easily removed from the paste forming mold 1.

[0031] By setting up a PPU flip-grip unit 40, in which the PPU robot arm 42 can directly drive the flip-grip mechanism 43 to complete the transfer of packaging material 2 from packaging material supply unit 30 to demolding unit 20, it replaces the dual power source drive mode of the Z-axis conveyor line and Y-axis conveyor line in the existing technology. Only a single power control is needed to realize the path transfer of packaging material 2, which effectively reduces power consumption and greatly simplifies the complexity of program settings. The flip-grip mechanism 43 integrates a 180-degree flip function and a power gripper 45, eliminating the need for an additional independent flip-grip mechanism 43 and simplifying the equipment structure. In addition, with the fixed-point operation design of demolding unit 20 and packaging material supply unit 30, the entire process of clamping, flipping, paste insertion and transfer of packaging material 2 can be precisely connected, improving the stability and efficiency of packaging material 2 transfer and paste shell filling.

[0032] Please see Figure 3-4Based on the above technical solution, a further proposed PPU manipulator 42 includes a fixed plate 421, a motor assembly 422, a U-shaped groove plate 423, a transverse linear guide rail 424, a longitudinal linear guide rail 425, and a swing arm 426. The fixed plate 421 is fixedly mounted on the fixed frame 41. The U-shaped groove plate 423 is fixedly mounted in front of the fixed plate 421 and has an inverted U-shaped groove 427. The motor assembly 422 is mounted on the fixed plate 421, and the motor shaft of the motor assembly 422 is located at the center of the inverted U-shaped groove 427. The transverse linear guide rail 424 is fixedly mounted on the fixed plate 421, and the longitudinal linear guide rail 425 is slidably connected to the transverse linear guide rail 426. On the linear guide rail 424, one end of the swing arm 426 is powered to the motor shaft of the motor assembly 422, and the other end of the swing arm 426 is rotatably connected to the fixing block 428. The fixing block 428 is guided and engaged with the inverted U-shaped slide groove 427. The fixing block 428 is fixedly installed on the longitudinal linear guide rail 425, and the flipping clamping mechanism 43 is fixedly installed at the lower end of the longitudinal linear guide rail 425. The motor assembly 422 drives the longitudinal linear guide rail 425 to move along the transverse linear guide rail 424 through the swing arm 426. With the guidance of the inverted U-shaped slide groove 427 of the U-shaped groove plate 423, the transfer path of the packaging material 2 can be precisely controlled to ensure the positional accuracy of actions such as clamping, flipping and inserting the paste. Two horizontal linear guides 424 and two vertical linear guides 425 are provided. The two horizontal linear guides 424 are distributed above and below the inverted U-shaped slide groove 427. Each of the two horizontal linear guides 424 has a slider, and a connecting plate 429 is installed on the slider of each of the two horizontal linear guides 424. Each of the two vertical linear guides 425 has two sliders. One slider of each of the two vertical linear guides 425 is installed on the connecting plate 429 of one of the horizontal linear guides 424, and the other slider of each of the two vertical linear guides 425 is installed on the connecting plate 429 of the other horizontal linear guide 424. The guide rails 425 are spaced apart; two transverse linear guide rails 424 are distributed vertically and connected to the sliders of the longitudinal linear guide rails 425 via connecting plates 429. The two longitudinal linear guide rails 425 are spaced apart and are both connected to the transverse guide rails via double sliders. This symmetrical structure of double guide rails and double sliders can distribute the force and avoid swaying or deviation caused by uneven force on a single guide rail, greatly improving motion stability and enhancing the load-bearing capacity of the mechanism to meet the needs of long-term high-frequency production. In addition, the overall structure achieves motion transmission through mechanical linkage without the need for additional power components. While continuing the energy-saving advantages of a single power source, it further reduces the risk of mechanical wear and extends the service life of the equipment.

[0033] Please see Figure 3-4Based on the above technical solution, it is further proposed that the fixing block 428 is fixedly installed at the middle position of the two longitudinal linear guide rails 425, so that the driving force transmitted by the swing arm 426 can be evenly applied to the two longitudinal linear guide rails 425, avoiding unilateral wear or movement jamming of the guide rails due to the offset of the force point; and the fixing block 428 is rotatably connected to a rotating shaft located between the two longitudinal linear guide rails 425. The rotating shaft is guided and slidably connected to the inverted U-shaped slide groove 427. The swing arm 426 is rotatably connected to the rotating shaft, so that the force of the swing arm 426 is always in the symmetrical center area of ​​the guide rail, reducing the torque deviation during the movement process and improving the smoothness and positional accuracy of the longitudinal linear guide rail 425 when sliding along the transverse linear guide rail 424.

[0034] Please see Figure 3 and Figure 5 Based on the above technical solution, it is further proposed that the flipping clamping mechanism 43 also includes a fixed base 46 installed at the lower end of the two longitudinal linear guide rails 425. This connection method allows the flipping clamping mechanism 43 to be stably assembled on the longitudinal linear guide rails 425, ensuring the stability of the overall structure and preventing loosening during transfer and flipping. The 180-degree flipping mechanism 44 includes a rotating shaft 441 movably connected to a fixed base 46 and a rotary motor 442 mounted on the fixed base 46 and powered by the rotating shaft 441. The power gripper 45 includes a gripping cylinder 451 mounted at the end of the rotating shaft 441 and a gripper body 452 powered by the gripping cylinder 451. The 180-degree flipping mechanism 44 uses the rotary motor 442 to directly power the rotating shaft 441, which can accurately control the rotation angle and speed of the rotating shaft 441 to ensure that the 180-degree flipping action of the packaging material 2 is accurate and in place. The power gripper 45 is driven by the gripping cylinder 451 to drive the gripper body 452. The gripping force can be precisely adjusted by the cylinder, which can stably grip the packaging material 2 and avoid damage to the packaging material 2 due to excessive gripping force. In addition, the air pipe connected to the clamping cylinder 451 is a spiral structure air pipe, which is wound around the rotating shaft 441 and connected to an external air pump by setting an adapter on the fixed seat 46, so that the air supply to the clamping cylinder 451 will not be affected when rotating.

[0035] 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.
