[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] See also Figure 1-Figure 3 , the utility model provides the following technical solutions:

[0029] A texture analyzer adhesion test probe, comprising:

[0030] Bottom plate 8;

[0031] The movable support plate 1 is arranged at the upper end of the bottom plate 8;

[0032] The force sensing element 2, the pressure roller bracket 3 and the pressure roller 7 are all arranged at the upper end of the bottom plate 8. The force sensing element 2 is connected to the pressure roller bracket 3, and the pressure roller 7 is rotatably connected to the pressure roller bracket 3.

[0033] The sample pressing plate 14 is provided on one side of the movable supporting plate 1;

[0034] The sample layer 12 is located in the sample pressing plate 14;

[0035] A horizontal movable platform 10 is provided on the upper side of the base plate 8;

[0036] Threaded holes are provided on both sides of the movable support plate 1. Fastening screws 9 are provided on both sides of the movable support plate 1. Fastening screws 9 are threadedly connected to the threaded holes. Fastening screws 11 are threadedly connected to the inner thread of the sample pressing plate 14.

[0037] In a specific embodiment of the present invention, the bottom plate 8 is a supporting part to ensure the stability of the structure. The movable support plate 1 is used to carry the sample and apply pressure. The force sensing element 2 is used to measure the force acting on the sample. It is a high-precision pressure sensor connected to the pressure roller bracket 3 to monitor and record data in real time. The pressure roller bracket 3 supports the pressure roller 7 and keeps it stable. The pressure roller 7 rolls on the sample surface to simulate the contact and friction process in actual application. The sample pressing plate 14 is used to fix the sample to be tested to ensure that it will not shift during the test. The sample pressure strip 12 enhances the stability of the sample fixation. The horizontal movable platform 10 can move in the horizontal direction to adjust the relative position between the pressure roller 7 and the sample to achieve adhesion force measurement under different test conditions. The fastening screw 9 is used to adjust the position of the movable support plate 1 and maintain its stability during operation. The fastening screw 11 adjusts the clamping force of the sample pressing plate 14 on the sample. The force sensing element 2 can accurately capture subtle changes in force value, ensuring the accuracy of the test results. Through the design of the horizontal movable platform 10 and the pressure roller 7, different contact and separation speeds can be simulated to improve the efficiency of use.

[0038] For details, please refer to Figure 1-Figure 3 A hanging ring is provided on one side of the horizontal movable platform 10, and the upper end of the base plate 8 is fixedly connected to the pulley bracket 5. One side end of the pulley bracket 5 is rotatably connected to two I-shaped wheels 13 through a rotating rod. A nylon rope is provided on the surface of the hanging ring, and the nylon rope is connected to the surface of the two I-shaped wheels 13. A weight 6 is provided at the other end of the nylon rope.

[0039] In this embodiment: the hanging ring is used to hang the nylon rope and provide a fulcrum. The pulley bracket 5 is provided with two groups of I-wheels 13 for supporting and guiding the rotational movement to ensure that the nylon rope transmits force smoothly. There are two I-wheels 13 in each group of pulley brackets 5 for changing the direction of the nylon rope so that it can extend downward from the hanging ring to the weight 6. The use of nylon rope ensures the smooth transmission of force while having certain strength and durability. The weight 6 is connected to the other end of the nylon rope to generate a constant downward pulling force. This force can be adjusted by replacing weights 6 of different masses, thereby accurately controlling the force applied to the horizontal moving platform 10. A closed force transmission chain is formed between the hanging ring and the weight 6 through the nylon rope, so the moving speed of the platform and the magnitude of the force applied to the sample can be accurately controlled.

[0040] For details, please refer to Figure 1-Figure 3 , the material of the sample pressing plate 14 is steel.

[0041] In this embodiment: the steel has high strength and rigidity to ensure that it is not easily deformed when subjected to external force, can effectively fix the sample, ensure stability during the test process, and can maintain a good surface condition even under long-term use or high pressure, thereby reducing test errors caused by wear.

[0042] For details, please refer to Figure 1-Figure 3 The pulley bracket 5 is made of a solid core structure.

[0043] In this embodiment, the solid structure has a higher material density than the hollow structure under the same volume, so that the pulley bracket 5 has better anti-bending and anti-torsion capabilities, ensuring structural stability when bearing loads and external forces.

[0044] For details, please refer to Figure 1-Figure 3 The upper end of the bottom plate 8 is fixedly connected to the pressure roller thrust shaft 4, and the pressure roller thrust shaft 4 is located on one side of the pressure roller bracket 3.

[0045] In this embodiment: the pressure roller thrust shaft 4 can limit the lateral movement of the pressure roller 7, ensuring that it runs on a predetermined track, avoiding deviation or shaking during the test, and improving the accuracy of the test. The pressure roller thrust shaft 4 provides additional guide support for the pressure roller 7, which helps the pressure roller 7 to maintain linear motion during the rolling process. The pressure roller thrust shaft 4 can help quickly locate the starting position of the pressure roller 7, facilitating initial setting or calibration work.

[0046] The working principle and usage process of the present invention are as follows: the sample to be tested is placed on the sample pressing plate 14, and the sample is fixed by tightening the screw 2 11 and the sample pressure strip 12. According to the test requirements, the position of the horizontal movable platform 10 is adjusted to ensure that the pressure roller 7 is in good contact with the sample surface. The equipment is started, and the pressure roller 7 begins to apply a preset pressure and rolls along the sample surface. The force sensing element 2 monitors and records the force exerted by the pressure roller 7 on the sample in real time, thereby obtaining the adhesion data. After the test is completed, the data is recorded and analyzed to obtain the adhesion evaluation result.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
