[0046] Synchronization rope 8, the synchronization rope 8 is wound around the circumferential surfaces of the two hanging rings 9 and is in contact with the spool 10.

[0047] In a specific embodiment of the present invention, the base 1 provides support for stably placing on the experimental table, the experimental platform 2 provides a stable working surface for placing the synchronous slide 13 to keep it stable, the synchronous slide 13 is used to support the test plate 3 and achieve its precise movement in the horizontal direction, the test plate 3 is used to place the test sample 5, the test sample 5 is placed on the upper side of the test plate 3, the item to be tested, the pressing plate 11 is provided with two to apply pressure to the test sample 5 to keep it stable, there are four tightening screws 12, used in pairs, threadedly connected to the test plate 3 and the experimental platform 2 to fix the position of the test plate 3, the sample fixture 14 is used to fix the test sample 5, and its size can be adjusted by the sample adjustment bolt 4, lower the force sensor 6 to a suitable position, the force sensor 6 is used to sense and measure the force applied during the test process, the synchronization bracket 7 plays a role in supporting and guiding the synchronization rope 8, the spool 10 is used to change the transmission direction of the synchronization rope 8, the two hanging rings 9 fix the position of the synchronization rope 8, the synchronization rope 8 is used to transmit motion to ensure the synchronous movement between the synchronous slide 13 and the force sensor 6.

The force sensor 6 records the change of the force value during the whole test process, providing data support for the experiment.

[0048] Specifically, please refer to Figure 1 - Figure 2 , the material of the test plate 3 is steel.

[0049] In this embodiment: Steel has a relatively high hardness and can withstand the pressure and wear that may occur during the test, ensuring the durability of the test plate.

[0051] In this embodiment, the contact surfaces of the clamping pieces have the same shape and size, which can ensure a uniform pressure distribution on the sample, avoid local stress concentration, and the clamping pieces are subjected to sandblasting treatment to increase friction and prevent the sample from sliding.

[0052] For details, please refer to Figure 1 - Figure 2 , and the synchronous rope 8 is made of nylon.

[0053] In this embodiment, nylon is famous for its high strength and can withstand a large tensile force without being easily broken, which is important for the role of the synchronous rope 8 in the texture analyzer to transmit force and stabilize the sample.

[0054] The working principle and usage process of the present utility model are as follows: The sample adjustment bolt 4 is first used to position and fix the sample fixture 14 to ensure that the test sample 5 is correctly placed. The synchronous slide 13 moves according to preset parameters, driving the sample on the test plate 3 to peel off in the 90-degree direction. The force sensor 6 monitors and records the force values received during the entire peeling process, and the data is transmitted to the control system in real time for processing and storage. The synchronous rope 8 and the spool 10 system ensure that the movement of the sample is stable and not affected by additional lateral forces, guaranteeing the accuracy of the test results. The force sensor 6 records the change in force values during the entire test process, providing data support for the experiment.
