Description

Technical Field

[0001] This application relates to the field of mechanical technology, and more specifically, to a raw material conveying system and a lipstick machine. Background Technology

[0002] In the cosmetics manufacturing industry, particularly in lipstick machines, the delivery and drip control of raw materials are crucial aspects of the manufacturing process. However, in practical applications, especially for the delivery of raw materials for cosmetics such as lipsticks, the high viscosity and adhesion of these materials often make it difficult for droplets to detach smoothly from the material outlet. This adhesion may stem from the physical properties of the raw material itself, such as viscosity and surface tension, or it may be related to the material and surface treatment of the inner wall of the material tube.

[0003] When raw material droplets cannot detach smoothly due to viscosity and adhesion, they will accumulate at the raw material outlet and even block the raw material pipe. In addition, the raw material droplets cannot detach in time to enter the mixing state, making subsequent mixing impossible. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, this application provides a raw material conveying system and a lipstick machine, so as to at least solve or alleviate the above-mentioned problems of the prior art. This technical solution can significantly improve safety and accuracy.

[0005] A raw material conveying system includes: at least one raw material pipe (1), a raw material pushing structure (2), and a raw material drop cutting structure (3). The raw material pipe (1) contains raw material, and the raw material pushing structure (2) is connected to the raw material pipe (1) to push the raw material contained in the raw material pipe (1) to the raw material outlet of the raw material pipe (1) to form a raw material drop by means of the operation of the raw material pushing structure (2); the raw material drop cutting structure (3) is connected to the raw material pipe (1) to generate airflow toward the raw material drop and cut the raw material drop by means of the airflow, so that the raw material drop leaves the raw material outlet and enters the raw material mixing chamber.

[0006] A lipstick machine includes the raw material conveying system described in any embodiment of this application.

[0007] In this embodiment, the raw material tube (1) contains raw material through the raw material pushing structure (2) and the raw material drop cutting structure (3). The raw material pushing structure (2) is connected to the raw material tube (1) so that the raw material contained in the raw material tube (1) is pushed to the raw material outlet of the raw material tube (1) to form a raw material drop through the action of the raw material pushing structure (2). The raw material drop cutting structure (3) is connected to the raw material tube (1) to generate airflow toward the raw material drop and cut the raw material drop through the airflow, so that the raw material drop leaves the raw material outlet and enters the raw material mixing chamber. Thus, the cooperation of the raw material pushing structure (2) and the raw material drop cutting structure (3) is realized. On the one hand, it ensures that the raw material can be pushed to the raw material outlet to form a raw material drop evenly and stably. Then, the raw material drop cutting structure (3) uses airflow to cut the raw material drop so that the raw material drop can smoothly leave the raw material outlet and enter the raw material mixing chamber for mixing.

[0033] See Figures 1A-4B As shown, a raw material conveying system includes: at least one raw material pipe (1), a raw material pushing structure (2), and a raw material droplet cutting structure (3). The raw material pipe (1) contains raw material, and the raw material pushing structure (2) is connected to the raw material pipe (1) to push the raw material contained in the raw material pipe (1) to the raw material outlet of the raw material pipe (1) to form a raw material droplet through the operation of the raw material pushing structure (2). The raw material droplet cutting structure (3) is connected to the raw material pipe (1) to generate an airflow toward the raw material droplet and cut the raw material droplet through the airflow, so that the raw material droplet leaves the raw material outlet and enters the raw material mixing chamber. The raw material includes at least one of pigment and base material.

[0034] In this embodiment, the raw material tube (1) contains raw material through the raw material pushing structure (2) and the raw material drop cutting structure (3). The raw material pushing structure (2) is connected to the raw material tube (1) so that the raw material contained in the raw material tube (1) is pushed to the raw material outlet of the raw material tube (1) to form a raw material drop through the action of the raw material pushing structure (2). The raw material drop cutting structure (3) is connected to the raw material tube (1) to generate airflow toward the raw material drop and cut the raw material drop through the airflow, so that the raw material drop leaves the raw material outlet and enters the raw material mixing chamber. Thus, the cooperation of the raw material pushing structure (2) and the raw material drop cutting structure (3) is realized. On the one hand, it ensures that the raw material can be pushed to the raw material outlet to form a raw material drop evenly and stably. Then, the raw material drop cutting structure (3) uses airflow to cut the raw material drop so that the raw material drop can smoothly leave the raw material outlet and enter the raw material mixing chamber for mixing.

[0035] Optionally, the raw material droplet cutting structure (3) includes: an airflow channel and an airflow control switch (32). The airflow channel is used to receive airflow input from an external airflow source. The airflow control switch (32) "opens" or "closes" the airflow channel to control the airflow input from the external airflow source to form an airflow towards the raw material droplet through the airflow channel.

[0036] Optionally, the airflow channel includes: an airflow input channel (31) and an airflow output channel (33). The airflow input channel (31) is used to receive airflow input from an external airflow source. The airflow control switch (32) "opens" or "closes" the connection between the airflow input channel (31) and the airflow output channel (33) to control the airflow input from the external airflow source to be input from the airflow input channel (31) to the airflow output channel (33) to form an airflow towards the raw material droplets.

[0037] Therefore, introducing a raw material droplet cutting structure (3) with an airflow input channel (31), an airflow control switch (32), and an airflow output channel (33) into the raw material conveying system has the following technical advantages:

[0038] (1) By using the airflow control switch (32), it is possible to accurately determine whether the airflow input from the external airflow source flows into the airflow output channel (33), thereby achieving precise control over the cutting of the raw material droplets. This precise control is crucial for ensuring the smooth detachment of the raw material droplets and maintaining the stability of the manufacturing process.

[0039] (2) The airflow control switch (32) allows users to adjust the intensity and duration of the airflow according to actual needs. For raw materials with different viscosity and adhesion, the best cutting effect can be found by adjusting the airflow parameters, thereby improving production efficiency and product quality.

[0040] Optionally, the airflow control switch (32) is disposed between the airflow input channel (31) and the airflow output channel (33) to "open" or "close" the connection between the airflow input channel (31) and the airflow output channel (33).

[0041] Optionally, the airflow control switch (32) includes a valve core and an electromagnet. When the electromagnet is energized, it generates an electromagnetic force, which attracts the valve core to keep the connection between the airflow input channel (31) and the airflow output channel (33) in an "open" state. When the electromagnet is stopped, the electromagnetic force disappears, causing the valve core to reset. The reset of the valve core keeps the connection between the airflow input channel (31) and the airflow output channel (33) in a "closed" state.

[0042] Optionally, the airflow control switch (32) further includes a sealed cavity in which the valve core is disposed. Electromagnets are disposed on both sides of the cavity to generate electromagnetic force when the electromagnets are energized. The electromagnetic force attracts the valve core so that the connection between the airflow input channel (31) and the airflow output channel (33) is in the "open" state.

[0043] Therefore, designing the airflow control switch (32) as a structure including a sealed cavity, a valve core, and electromagnets arranged on both sides has the following technical advantages:

[0044] (1) By energizing and de-energizing the electromagnet, the movement of the valve core can be quickly controlled, thereby realizing the rapid switching between the airflow input channel (31) and the airflow output channel (33). This design makes the system's airflow control very precise, and can quickly open or close the airflow channel as needed.

[0045] (2) The mechanical structure composed of electromagnet and valve core is simple and reliable. Due to the characteristics of electromagnetic force, the valve core has stable and repeatable operation. This design enables the airflow control switch (32) to maintain high reliability during long-term use.

[0046] (3) When airflow is not needed, simply stop energizing the electromagnet to close the airflow channel, thereby saving energy. In addition, the electromagnet itself has relatively low energy consumption, which helps to reduce the energy consumption of the entire system.

[0047] (4) Due to its relatively simple structure, the airflow control switch (32) is also relatively easy to maintain and replace. When a problem occurs, it can be quickly located and resolved, reducing the time of production interruption.

[0048] Optionally, if there are multiple raw material tubes (1), the multiple raw material tubes (1) are divided into several groups. For each group of raw material tubes, one raw material tube (1) corresponds to one raw material drop cutting structure (3). The multiple raw material drop cutting structures (3) corresponding to each group of raw material tubes share the same airflow input channel (31). Different raw material tubes (1) correspond to independent airflow output channels (33) and independent airflow control switches (32) to control the corresponding raw material drop cutting structure (3) to "open" or "close" based on one airflow control switch (32).

[0049] Therefore, if there are multiple raw material pipes (1), and these raw material pipes (1) are divided into several groups, each group of raw material pipes is equipped with an independent airflow control switch (32) and an independent airflow output channel (33), but they share the same airflow input channel (31), the following technical advantages are available:

[0050] (1) Multiple raw material pipes (1) share the same airflow input channel (31), which can simplify the pipeline design of the system, reduce the number of required airflow sources, and thus reduce the overall complexity and cost of the system.

[0051] (2) The grouping design makes each group of raw material pipes and its corresponding raw material drip cutting structure (3) a relatively independent unit. This design facilitates group management and maintenance, and improves work efficiency.

[0052] (3) Each raw material pipe (1) corresponds to an independent airflow control switch (32) and airflow output channel (33), enabling the system to control the raw material droplet cutting operation of each raw material pipe (1) individually. This flexible control method can meet the different needs that may exist when cutting different raw material pipes (1).

[0053] (4) By independently controlling the raw material droplet cutting operation of each raw material tube (1), the system can ensure that the raw material droplets of each raw material tube (1) are cut off at the most appropriate time, thereby improving production efficiency and product quality.

[0054] Optionally, multiple raw material drop cutting structures (3) are fixed side by side on a support in such a way that they are aligned with the raw material outlets of their respective corresponding raw material tubes (1).

[0055] Optionally, the raw material conveying system further includes a transition connection channel (34), one end of which is connected to the raw material outlet and the other end is connected to the raw material droplet cutting structure (3) to convey the airflow generated toward the raw material droplet to the raw material outlet and cut the raw material droplet.

[0056] Therefore, introducing a transitional connecting channel (34) into the raw material conveying system as a bridge connecting the raw material outlet and the raw material drip cutting structure (3) has the following technical advantages:

[0057] (1) The transition connection channel (34) can ensure that the airflow generated from the raw material droplet cutting structure (3) is accurately guided to the raw material outlet to effectively cut the raw material droplet that is about to be formed.

[0058] (2) Through the design of the transition connection channel (34), the airflow can reach the raw material outlet more directly and quickly, thereby improving the cutting efficiency, helping to reduce the waste of raw material droplets, and improving production efficiency and product quality.

[0059] (3) Due to the precise guiding effect of the transition connection channel (34), the system can utilize airflow energy more effectively, reduce unnecessary energy loss, and help reduce the system's energy consumption and improve energy utilization efficiency.

[0060] (4) The introduction of the transition connection channel (34) makes the structure of the raw material conveying system more compact and simplified, which not only facilitates the installation and maintenance of the system, but also helps to improve the stability and reliability of the system.

[0061] (5) The design of the transition connection channel (34) can be adjusted and optimized according to actual needs to adapt to the requirements of different raw material outlets and raw material drip cutting structures (3), so that the system has stronger adaptability and flexibility and can adapt to a wider range of application scenarios.

[0062] Optionally, the raw material conveying system further includes: a raw material injection seat (35), which is disposed below the raw material pipe (1) and communicates with the raw material outlet. The transition connection channel (34) is communicated with the raw material injection seat (35) so that one end of it is communicated with the raw material outlet. The raw material droplet leaves the raw material outlet and passes through the raw material injection seat (35) into the raw material mixing chamber.

[0063] Therefore, introducing a raw material injection seat (35) into the raw material conveying system and connecting it to the transition connection channel (34) and the raw material outlet has technical advantages:

[0064] (1) The setting of the raw material injection seat (35) provides an optimized transport path, ensuring that the raw material droplets can smoothly and accurately enter the raw material mixing chamber after leaving the raw material outlet. This design reduces the risk of loss and contamination of raw material droplets during transport.

[0065] (2) The structural design of the raw material injection seat (35) can further enhance the guidance of the raw material droplets, ensuring that the raw material droplets can enter the raw material mixing chamber according to the predetermined trajectory. This is especially important for application scenarios that require precise control of the position and distribution of raw material droplets.

[0066] (3) Enhance the jetting effect of raw material droplets: By providing airflow to the raw material jetting seat (35) through the transition connecting channel (34), a certain jetting force can be generated, which helps the raw material droplets to better detach from the raw material outlet and enter the raw material mixing chamber. This jetting effect helps to improve the mixing effect of raw material droplets and product quality.

[0067] (4) The introduction of the raw material injection seat (35) makes the structure of the raw material conveying system more compact and simplified. This not only facilitates the installation and maintenance of the system, but also helps to improve the stability and reliability of the system.

[0068] (5) The optimized raw material droplet transport path and spraying effect can improve the system's production efficiency. The raw material droplets can enter the raw material mixing chamber more quickly and accurately, thereby reducing waiting time and resource waste in the production process.

[0069] (6) The raw material injection seat (35) can be designed and adjusted according to different application requirements. For example, its shape, size or position can be adjusted to meet the requirements of different raw material outlets and raw material mixing chambers. This flexibility allows the system to adapt to a wider range of application scenarios.

[0070] Optionally, if there are multiple raw material pipes (1), each raw material pipe (1) corresponds to a raw material injection seat (35), and multiple raw material injection seats (35) are connected to form a raw material injection seat integrated structure, which is located below multiple raw material pipes (1).

[0071] Optionally, the raw material pipe (1) includes: an upper pipe body (11), an intermediate pipe body (12), and a lower pipe body (13). The upper pipe body (11) is connected to the intermediate pipe body (12), and the intermediate pipe body (12) is connected to the lower pipe body (13) to form a cavity for accommodating the raw material (14).

[0072] Optionally, the outer wall of the upper tube (11) is connected to a driving device (16) via a transmission mechanism (15), and a lead screw (11) is provided in the upper tube (11). A pressure plate (112) meshes with the lead screw (11). When the driving device (16) drives the upper tube (11) to rotate via the transmission mechanism (15), the upper tube (11) drives the lead screw (11) to rotate. The rotation of the lead screw (11) drives the pressure plate (112) to press down, so as to push the raw material (14) in the cavity toward the lower tube (13) until a raw material (14) that can flow out of the lower tube (13) is formed.

[0073] like Figures 5A-10BAs shown, the raw material pipe may include: an upper pipe body (11), an intermediate pipe body (12), and a lower pipe body (13). The upper pipe body (11) is connected to the intermediate pipe body (12), and the intermediate pipe body (12) is connected to the lower pipe body (13) to form a cavity for accommodating the raw material (14). The outer wall of the upper pipe body (11) is connected to a driving device (16) through a transmission mechanism (15), and a lead screw (111) is provided in the upper pipe body (11). A pressure plate (112) engages on the rod (111) so that when the drive device (16) drives the upper tube (11) to rotate through the transmission mechanism (15), the upper tube (11) drives the lead screw (111) to rotate, and the rotation of the lead screw (111) drives the pressure plate (112) to press down, so as to push the raw material (14) in the cavity toward the lower tube (13) until the raw material (14) can flow out from the lower tube (13).

[0074] In this embodiment, the meshing design of the lead screw (11) and the pressure plate (112) allows the lead screw (11) to rotate and drive the pressure plate (112) to press down when the drive device (16) drives the upper tube (11) to rotate through the transmission mechanism (15). This mechanical structure ensures that the raw material (14) can be accurately and stably pushed into the lower tube (13), achieving precise distribution of the raw material. By controlling the rotation speed and direction of the drive device (16), the flow rate and direction of the raw material can be further controlled to meet different usage requirements. The upper tube (11) is connected to the drive device (16) through the transmission mechanism (15), so that the entire raw material distribution process can be automated by controlling the drive device (16), greatly improving the convenience and efficiency of operation. The docking design between the upper tube (11), the middle tube (12), and the lower tube (13) ensures the structural stability and sealing of the raw material tube (1), avoiding the problem of raw material leakage or contamination. Meanwhile, the selection and configuration of the transmission mechanism (15) and the drive device (16) also take into account the reliability and durability of the equipment, ensuring that the raw material pipe (1) can operate stably for a long time.

[0075] Optionally, the upper end of the upper tube (11) is provided with a tooth (113) on its outer wall. The transmission mechanism (15) includes a transmission sleeve (151) and a helical gear (152). The transmission sleeve (151) is provided with a groove (1511). The transmission sleeve (151) engages with the tooth (113) in the upper tube (11). The helical gear (152) meshes with the transmission sleeve (151). The driving device (16) is connected to the helical gear (152) so that the driving device (16) drives the helical gear (152) to rotate. The rotation of the helical gear (152) drives the transmission sleeve (151) to rotate. The rotation of the transmission sleeve (151) drives the upper tube (11) to rotate, thereby driving the lead screw (111) to rotate.

[0076] The raw material pushing structure (2) in the above embodiments may include the lead screw (111) and pressure plate (112). Of course, in some embodiments, it may also include the transmission mechanism (15) and drive device (16). The specific structure design can be used to determine the specific structure. However, as long as the function of this application is achieved, it is acceptable.

[0077] Therefore, the transmission mechanism (15) with a convex tooth (113), a transmission sleeve (151), and a helical gear (152) added to the above-mentioned raw material pipe (1) design has the following technical advantages:

[0078] (1) The engagement design between the protruding tooth (113) and the groove (511) on the transmission sleeve (151) ensures the precise connection and transmission between the upper tube body (11) and the transmission sleeve (151). This design avoids slippage or error during the transmission process and ensures the precise distribution of raw materials (14).

[0079] (12) The meshing design of the helical gear (152) and the transmission sleeve (151), as well as the connection between the helical gear (152) and the drive device (16), constitute a highly efficient power transmission system. This design enables the power of the drive device (16) to be transmitted quickly and accurately to the upper tube body (11), thereby driving the lead screw (11) to rotate and realize the propulsion of the raw materials.

[0080] (3) The integrated design of the convex tooth (113), transmission sleeve (151) and helical gear (152) makes the entire transmission mechanism (15) compact and space-saving. This is very important for the overall design of the raw material pipe (1) because it helps to reduce the size and weight of the equipment and improve its portability and flexibility.

[0081] (4) The rotation of the helical gear (152) drives the transmission sleeve (151) to rotate, which in turn drives the upper tube body (11) to rotate. This transmission method has the characteristics of stability and reliability, and can ensure that the transmission mechanism (15) can still maintain stable performance during long-term and high-frequency use, without loosening or failure.

[0082] (5) Since the structure of the transmission mechanism (15) is relatively simple and the connection between each component is clear, the relevant components can be easily disassembled and replaced during equipment maintenance, which reduces maintenance costs and difficulty.

[0083] Optionally, the lead screw (11) is connected to a lead screw seat (111), the lead screw seat (111) is located in the inner cavity of the upper tube (11), and the top of the lead screw seat (111) engages with the top of the upper tube (11) to fix the lead screw seat (111) in the inner cavity of the upper tube (11) so that the lead screw (11) can rotate synchronously when the upper tube (11) rotates.

[0084] Therefore, in the design of the raw material pipe (1), the lead screw (11) is fixed in the inner cavity of the upper pipe body (11) through the lead screw seat (111), which has the following technical advantages:

[0085] (1) The lead screw seat (111) stably fixes the lead screw (11) in the inner cavity of the upper tube (11). When the upper tube (11) is driven to rotate, the lead screw (11) can rotate synchronously and stably. This design ensures that the raw material (14) can be pushed continuously and smoothly, avoiding the possible stagnation or unevenness of the raw material during the pushing process.

[0086] (2) The top of the lead screw seat (111) is locked and fixed to the top of the upper tube body (11). This design makes the installation and removal of the lead screw seat (111) simple and convenient. When it is necessary to repair or replace the lead screw (11) or the lead screw seat (111), it can be easily removed, reducing maintenance costs and time.

[0087] (3) The fixing function of the lead screw seat (111) reduces the shaking and friction of the lead screw (11) during rotation, thereby reducing the wear and noise of the equipment. This is of great significance for improving the service life of the equipment and the comfort of the working environment.

[0088] (4) Through the fixing effect of the lead screw seat (111), the lead screw (11) can work more stably, reducing the failure and downtime caused by unstable rotation. This design improves the reliability and stability of the equipment and ensures the continuity and accuracy of the raw material distribution process.

[0089] Optionally, the drive device (16) includes a motor (161), a power output frame (162), and a power output shaft (163). The motor (161) is connected to the power output frame (162) to drive the power output frame (162) to rotate. The power output shaft (163) is connected to the power output frame (162) to drive the power output shaft (163) to rotate through the rotation of the power output frame (162). The helical gear (152) is sleeved on the power output shaft (163) to drive the helical gear (152) to rotate through the rotation of the power output shaft (163). The rotation of the helical gear (152) drives the transmission sleeve (151) to rotate.

[0090] Therefore, in the design of the raw material pipe (1), a drive device (16) including a motor (161), a power output frame (162) and a power output shaft (163) is introduced to drive the helical gear (152) and the transmission sleeve (151), thereby driving the upper pipe body (11) and the lead screw (11) to rotate, which has the following technical advantages:

[0091] (1) The motor (161) serves as a power source and can output power stably and efficiently. Through the transmission of the power output frame (162) and the power output shaft (163), the power can be transmitted to the helical gear (152) without loss, thereby ensuring the rapid and precise rotation of the transmission mechanism (15) and the upper tube (11).

[0092] (2) The motor (161) usually has a speed regulation function, which can precisely control the speed and direction of rotation. This allows the pushing speed of the raw material (14) to be adjusted as needed, so as to achieve precise raw material distribution.

[0093] (3) Using an electric motor (161) as a power source can automate the raw material distribution process. Users only need to set the corresponding parameters, and the equipment can automatically complete the pushing and distribution of raw materials, reducing the difficulty and labor intensity of manual operation.

[0094] (4) The combination of the motor (161), power take-off frame (162), and power take-off shaft (163) has high operational stability and reliability. This design reduces downtime caused by mechanical failures and improves the overall performance and service life of the equipment.

[0095] (5) The relative independence of the motor (161) and the transmission mechanism (15) makes the maintenance and upkeep of the equipment simpler and more convenient. When a component fails, it can be replaced or repaired individually without disassembling the entire equipment.

[0096] Optionally, the lower tube (13) includes a nozzle (131) and a locking cap (132). The nozzle (131) is connected to the intermediate tube (12) so that the raw material (14) can be pushed outside the raw material tube (1). The locking cap (132) is used to lock the connection when the nozzle (131) is connected to the intermediate tube (12).

[0097] Therefore, in the design of the raw material pipe (1), the design of the lower pipe body (13) including the nozzle (131) and the locking cap (132) has the following technical advantages:

[0098] (1) The nozzle (131) is directly connected to the intermediate tube (12), so that the raw material (14) can be smoothly pushed from the raw material tube (1) to the outside. This design simplifies the raw material distribution process and improves the convenience of operation.

[0099] (2) The locking cap (132) provides a locking function when the nozzle (131) is connected to the intermediate tube (12), effectively preventing waste or contamination of raw materials due to accidental leakage during transportation or storage. This design increases the safety and reliability of the raw material tube (1).

[0100] (3) The locking cover (132) can not only prevent raw material leakage, but also protect the nozzle (131) from external environmental corrosion, such as dust and moisture, when the raw material is not in use, thereby extending the service life of the nozzle.

[0101] (4) The design of the locking cover (132) allows the nozzle (131) to be easily cleaned and maintained when needed. When the nozzle is clogged or needs cleaning, the user can easily access the nozzle by opening the locking cover to perform the necessary cleaning or maintenance work.

[0102] (5) The combined design of the nozzle (131) and the locking cap (132) makes the raw material tube (1) more user-friendly and improves the user's operating experience and satisfaction. Users can easily control the distribution of raw materials according to their own needs without worrying about problems such as raw material leakage or nozzle damage.

[0103] Alternatively, for example, the nozzle (131) may be connected to the intermediate tube (12) via a set collar (133).

[0104] Optionally, the lower tube body (13) further includes a locking spring (133), which engages on the outer wall of the locking cover (132) to lock the locking cover (132) when the locking cover (132) locks the connection.

[0105] Therefore, in the design of the raw material pipe (1), the introduction of a locking spring (133) into the lower pipe body (13) has the following technical advantages:

[0106] (1) When the locking cover (132) locks the connection between the nozzle (131) and the intermediate tube (12), the locking spring (133) can be stably locked on the outer wall of the locking cover (132), ensuring that the connection between the locking cover (132) and the raw material tube (1) is tight and firm. This design effectively prevents the problem of raw material leakage caused by accidental loosening and improves the safety and reliability of the raw material tube (1).

[0107] (2) The use of the locking spring (133) makes the locking operation of the latch cover (132) simpler and faster. The user only needs to align the latch cover (132) with the nozzle (131) and rotate it, and the locking spring (133) will automatically snap into the outer wall of the latch cover (132) to complete the locking process. This design reduces the user's operation steps and time, and improves the efficiency of use.

[0108] (3) The locking circlip (133) is usually made of elastic materials, such as stainless steel or spring steel, which have good wear resistance and corrosion resistance. This design enables the locking circlip (133) to maintain stable performance during long-term use, and it is not easy to be damaged or deformed, thereby extending the service life of the raw material tube (1).

[0109] (4) The design of the locking spring (133) enables the raw material tube (1) to adapt to different working environments and conditions. Whether in high temperature, low temperature or humid environment, the locking spring (133) can maintain a stable locking effect, ensuring that the raw material tube (1) can work normally in various environments.

[0110] (5) Since the locking circlip (133) is simple in design and easy to replace, when the locking circlip (133) is damaged or worn, the user can easily remove it and replace it with a new locking circlip (133) without disassembling or repairing the entire raw material tube (1). This design reduces the maintenance cost and difficulty of the raw material tube (1).

[0111] Optionally, the lower tube body (13) further includes an anti-backflow structure (134), which is disposed in the nozzle (131). When the raw material (14) is to be pushed outside the raw material tube (1), the anti-backflow device is closed so that the raw material (14) can be pushed outside the raw material tube (1). When the pushing of the raw material (14) to the outside of the raw material tube (1) is to be stopped, the anti-backflow device is opened so that the raw material (14) is blocked inside the raw material tube (1).

[0112] Therefore, the anti-backflow structure (134) included in the lower pipe body (13) plays a key role in the design of the raw material pipe (1) and has the following technical benefits:

[0113] (1) The anti-backflow structure (134) in the nozzle (131) ensures that when the material (14) is stopped from being pushed to the outside of the material pipe (1), the material will not flow back into the pipe due to gravity or other reasons. This function is crucial in keeping the inside of the material pipe (1) clean and preventing material contamination.

[0114] (2) When it is necessary to push the raw material (14) to the outside of the raw material pipe (1), the anti-backflow device is closed, allowing the raw material to flow out smoothly. This design simplifies the operation process and improves work efficiency.

[0115] (3) By effectively preventing raw material backflow, the anti-backflow structure (134) reduces the waste of raw materials and avoids pipeline contamination and raw material cross-contamination that may be caused by backflow.

[0116] (4) The anti-backflow structure (134) is part of the design of the raw material pipe (1), which increases the stability and reliability of the entire equipment. Its precise design and reliable performance ensure the stable operation of the raw material pipe (1) under various working conditions.

[0117] (5) The design of the anti-backflow structure (134) enables it to adapt to different application scenarios, including those requiring precise control of raw material flow and prevention of backflow. This flexibility has led to the widespread use of the raw material pipe (1) in many industries.

[0118] (6) The anti-backflow structure (134) is usually designed as a detachable or washable component, which makes it easy to maintain and clean when needed, extending the service life of the raw material pipe (1).

[0119] Optionally, the anti-backflow structure (134) includes a ball (1341) and a spring (1342) located in the nozzle (131). The spring (1342) presses against the ball (1341). When the raw material (14) is to be pushed outside the raw material tube (1), the spring (1342) is squeezed so that the ball (1341) opens the nozzle (131) so that the raw material (14) can be pushed outside the raw material tube (1). When the pushing of the raw material (14) to the outside of the raw material tube (1) is to be stopped, the spring (1342) returns to its original state so that the ball (1341) blocks the nozzle (131) so that the raw material (14) is blocked inside the raw material tube (1).

[0120] Therefore, the anti-backflow structure (134) consisting of a ball (1341) and a spring (1342) has the following technical advantages in the design of the raw material pipe (1):

[0121] (1) A simple and efficient anti-backflow mechanism is achieved by combining a ball (1341) and a spring (1342). When the raw material (14) is pushed, the ball (1341) is pushed open, allowing the raw material to pass through; when the pushing stops, the ball (1341) is quickly reset under the action of the spring (1342), blocking the nozzle (131) and effectively preventing the raw material from flowing back.

[0122] (2) Because the anti-backflow structure (134) can quickly and accurately control the flow of raw materials, it helps to improve the accuracy of raw material distribution. This structure provides reliable performance in applications such as precision coating, dispensing, or other applications that require precise control of raw material quantity.

[0123] (3) By preventing raw material backflow, the accumulation and sedimentation of raw materials in the pipeline are reduced, thereby reducing the risk of pipeline blockage. This helps to keep the raw material pipe (1) unobstructed and extend the service life of the equipment.

[0124] (4) Effectively preventing raw material backflow means reducing the waste of raw materials caused by backflow. At the same time, it avoids pipeline contamination and cross-contamination of raw materials that may be caused by raw material backflow, and maintains the purity and consistency of raw materials.

[0125] (5) The anti-backflow structure consisting of the ball (1341) and spring (1342) is relatively simple, easy to disassemble and clean. When replacement or cleaning is required, the user can easily complete these operations and keep the equipment in good condition.

[0126] (6) This anti-backflow structure is suitable for a variety of different types of raw materials and working environments. Whether it is a viscous liquid, a powdery substance or other types of materials, as long as the appropriate ball (1341) and spring (1342) are selected, an effective anti-backflow function can be achieved.

The tube body has a cavity for accommodating raw material (14). The outer wall of the tube body is connected to a driving device (16) through a transmission mechanism (15). The screw (11) is provided in the tube body. The pressure plate (112) is engaged on the screw (11). When the driving device (16) drives the tube body to rotate through the transmission mechanism (15), the tube body drives the screw (11) to rotate. The rotation of the screw (11) drives the pressure plate (112) to press down, so as to push the raw material (14) in the cavity toward the outside of the tube body until a raw material (14) that can flow out of the tube body is formed.

[0128] Based on the above embodiments, a lipstick machine is provided, which includes the raw material conveying system described in any embodiment of this application, wherein the raw materials in each raw material tube (1) are of different colors, and the raw materials in multiple raw material tubes (1) can be mixed to obtain the desired lipstick color.
