[0043] Force sensing element 11, the force sensing element 11 is provided on the upper side of the base 3;

[0044] Lipstick model 9, the lipstick model 9 is provided at the lower end of the force sensing element 11;

[0045] Lipstick fixing fixture 10, the lipstick fixing fixture 10 is fixedly connected to the surface of the lipstick model 9, and the lipstick fixing fixture 10 is located at the lower end of the force sensing element 11;

[0046] The upper end of the base 3 is fixedly connected with a pulley bracket 4. One side end of the pulley bracket 4 is rotatably connected with a winding drum 5 through a connecting rod, and a weight 2 is provided at the lower end of the pulley bracket 4.

[0047] In a specific embodiment of the present utility model, the texture analyzer fixing platform 1 and the base 3 provide stable support for the device. The clamping table 6 is used to support the slide rod, and the slide rod ensures the linear movement of the sliding block 7. The sliding block 7 freely slides along the slide rod to achieve displacement in the horizontal direction. The free translation slide 12 can move vertically along the sliding block 7 to achieve multi-dimensional displacement control. The test paper bracket 8 is used to fix the test paper and simulate the lip contact surface. The test paper pressing plate 13 is connected to the test paper bracket 8 through the pressing plate fixing screw 14 and is used to press the test paper to ensure its flatness and tight fit. There are two groups of the test paper pressing plate 13 and the pressing plate fixing screw 14. One of the two pressing plate fixing screws 14 connects the test paper pressing plate 13 and the test paper bracket 8, and the other connects the free translation slide 12 and the test paper bracket 8 to ensure the stability of the test paper during the test. The force sensing element 11 is used to measure the force value generated during lipstick application and feedback the application performance data. The lipstick model 9 simulates the actual shape of the lipstick and is used to receive the application action of the test paper. The lipstick fixing fixture 10 is used to fix the lipstick to be tested to ensure the position of the lipstick remains unchanged during the test. The pulley bracket 4 supports and positions the winding drum 5 and at the same time provides a rotational connection point for the connecting rod. The pulley bracket 4 ensures that the winding drum 5 can rotate smoothly without generating additional friction, so as to accurately transmit the magnitude of the force. Hang the nylon rope on one side of the free translation slide 12, then wind it around the surface of the winding drum 5, and connect the other end to the weight 2 to lift the weight 2. The mass of the weight 2 can be adjusted by changing its quantity to simulate different application pressures. The force sensing element 11 can accurately measure the change of the force value during the application process, improving the accuracy of the test result. Through the design of the lipstick model 9 and the lipstick fixing fixture 10, it simulates the actual use environment and enhances the authenticity and reliability of the test. The combination of the free translation slide 12 and the sliding block 7 provides multi-dimensional displacement control, facilitating the adjustment of the test angle and distance.

[0048] For details, please refer to Figure 1 - Figure 2 , and the sliding block 7 is bolted to the freely translatable slide 12.

[0049] In this embodiment: The bolt connection provides sufficient rigidity and stability to ensure that the freely translatable slide 12 does not experience unnecessary shaking or displacement during the application test, which is crucial for obtaining accurate test results. If the position of the freely translatable slide 12 needs to be adjusted, the bolts can be loosened, the position adjusted, and then tightened again, which gives the device a certain degree of flexibility and allows for fine-tuning according to different test requirements.

[0050] For details, please refer to Figure 1 - Figure 2 , and the sliding block 7 matches the slide bar.

[0051] In this embodiment: The aperture diameter or groove width of the sliding block 7 is slightly larger than the diameter or width of the slide bar, but not so large as to cause obvious gaps or frictional resistance during sliding, so as to reduce the frictional force during sliding and ensure smooth operation over a long period of use.

[0052] For details, please refer to Figure 1 - Figure 2 , and the material of the pulley bracket 4 is a solid structure.

[0053] In this embodiment: A solid structure usually has high strength and rigidity, can withstand large external forces without being easily deformed, and the solid-structured pulley bracket 4 is more durable in the face of wear and impact, which can extend the service life of the device.

[0054] The working principle and usage process of the present utility model: Fix the lipstick on the texture analyzer probe, lay a test paper flat on a freely translatable flat plate to ensure effective contact between the lipstick and the test paper, apply a constant force to the moving platform to simulate the force applied by a human hand through the lipstick on the lips, then turn on the texture analyzer to make the lipstick slide on the test paper, record the frictional force between the lipstick and the test paper, and reflect the spreadability of the lipstick by the magnitude of the test force. Fix the freely translatable slide 12 on the fixed platform 1 of the texture analyzer, loosen the pressure plate fixing screw 14, remove the test paper pressure plate 13, lay the test paper on the test paper bracket 8, then press the test paper with the test paper pressure plate 13 and tighten the pressure plate fixing screw 14. Then fix the lipstick on the force sensor 11 with the lipstick fixing fixture. The force sensor 11 is connected to the texture analyzer. Adjust the angle, hang the appropriate weight 2 on one side of the nylon rope, and turn on the texture analyzer to start the test.

[0055] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
