[0002] The extensibility of dough is an important indicator of its ability to hold fillings, and it is commonly used in laboratory measurements with dough measuring fixtures from physical property testing instruments. However, existing dough measuring fixtures have relatively large center hole spacing, making them particularly unsuitable for determining the extensibility of wonton and glutinous rice ball wrappers.

[0003] With the increasing demand for industrial production of glutinous rice balls and cold skin noodles, research on relatively soft dough formulations has increased year by year. However, due to their soft texture and difficulty in fixing, the dough measurement fixtures of current physical property testing instruments cannot meet the growing scientific research needs.

[0016] According to the present invention, a test platform for testing the extensibility of face skin is provided, wherein the first clamping plate and the second clamping plate are rectangular plates.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, 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 scope of protection of this utility model.

[0030] The following is combined with Figures 1-3 This invention describes a test stand for testing the extensibility of facial skin.

[0031] like Figure 1 As shown in the figure, this utility model embodiment provides a test platform for testing the extensibility of dough sheets, used to clamp dough sheet samples, including a first clamping plate 1 and a second clamping plate 2. The dough sheet sample can be a pancake wrapper, dumpling wrapper, wonton wrapper, cold skin noodle wrapper, etc.

[0032] The first clamping plate 1 has a first through hole 101, which is a crucial position for placing the dough sample. The second clamping plate 2 is detachably connected to the top of the first clamping plate 1, meaning the second clamping plate 2 and the first clamping plate 1 are stacked vertically. The second clamping plate 2 has a second through hole 201; and the second through hole 201 is correspondingly arranged to the first through hole 101, meaning the second through hole 201 and the first through hole 101 are connected vertically to form a smooth channel. The dough sample is clamped between the first through hole 101 and the second through hole 201, and different sized spherical probes 10 are used to connect to the instrument for measurement depending on the softness or hardness of the dough.

[0033] The top side of the first through hole 101 is provided with a first arc chamfer 102, and the bottom side of the second through hole 201 is provided with a second arc chamfer 202. The first clamping plate 1 and the second clamping plate 2 clamp the dough sample at the first arc chamfer 102 and the second arc chamfer 202 to distribute the stress as evenly as possible, avoid the dough sample from breaking at the clamping position and generating abnormal values, and ensure that the extensibility of soft dough samples such as wonton wrappers can be accurately characterized. The operation is simple and the measurement accuracy is guaranteed, thereby achieving efficient testing of dough extensibility.

[0034] like Figure 1 As shown, in this embodiment of the invention, the dough sample is carefully placed on the first clamping plate 1, and then the second clamping plate 2 is placed on top to clamp and fix the dough sample. The first clamping plate 1 and the second clamping plate 2 are respectively provided with a first through hole 101 and a second through hole 201, both of which are circular, allowing the circular dough sample to be exposed. Depending on the sample's hardness, a spherical probe 10 of different sizes is connected to the instrument for measurement. During the test, the first clamping plate 1 and the second clamping plate 2 tightly clamp the dough sample at the first rounded chamfer 102 and the second rounded chamfer 202. This unique clamping method effectively disperses stress, preventing the dough sample from breaking due to stress concentration at the clamping position, thereby preventing the generation of abnormal values.

[0035] In some feasible embodiments of this utility model, the opposing surfaces of the first clamping plate 1 and the second clamping plate 2 are both set as frosted surfaces. The fine particles densely distributed on the frosted surface significantly increase the contact area between the first clamping plate 1 and the dough sample, as well as between the second clamping plate 2 and the dough sample. At the same time, the roughness is improved, which gently but powerfully grips the dough sample and prevents it from shifting or slipping during the force test by the spherical probe 10.

[0036] The frosted surface can be achieved by surface treatment of the opposing surfaces of the first clamping plate 1 and the second clamping plate 2, or by pasting a relatively rough surface layer onto the opposing surfaces of the first clamping plate 1 and the second clamping plate 2, as long as it can increase the friction between the opposing surfaces of the first clamping plate 1 and the second clamping plate 2.

[0037] In some feasible embodiments of this utility model, fasteners 3 are also included. Fasteners 3 are evenly disposed on the first clamping plate 1 and the second clamping plate 2. Fasteners 3 are used to clamp the first clamping plate 1 and the second clamping plate 2, providing strong assistance for the cooperation of the first clamping plate 1 and the second clamping plate 2. Fasteners 3 ensure that during the testing process, force is applied simultaneously from multiple directions to tightly pull the first clamping plate 1 and the second clamping plate 2 together. As the fasteners 3 are gradually tightened, the two clamping plates gradually come into contact from their initial state, holding the dough sample securely with just the right amount of force. This prevents the dough sample from shifting during testing due to excessively loose clamping, and also prevents damage to the sample due to excessive force.

[0038] In some feasible embodiments of this utility model, a bracket (not shown in the figure) is also included to support the first clamping plate 1. The first clamping plate 1 is placed on the bracket. The bracket provides the first clamping plate 1 with a horizontal, stable and appropriately high working platform, which not only solves the problem of placing the test bench in different working scenarios, but also makes it easier for operators to perform soft leather tests by optimizing the operating height.

[0039] In some feasible embodiments of this utility model, the thickness of the first clamping plate 1 and the second clamping plate 2 is 8-10 mm. The thickness of 8-10 mm gives the clamping plates sufficient rigidity, enabling them to maintain a stable shape without bending or deforming when subjected to the testing force applied by the spherical probe 10. More preferably, the thickness is 9 mm.

[0040] like Figure 2 and Figure 3 As shown, the chamfer radius of the first rounded chamfer 102 and the second rounded chamfer 202 is 1.5 mm. The 1.5 mm chamfer radius can effectively distribute the stress on the skin sample at the clamping position. When the spherical probe 10 applies a pulling force to the skin sample, the curved surface structure of the first rounded chamfer 102 and the second rounded chamfer 202 can evenly distribute the stress over a large area, avoiding sample breakage caused by stress concentration.

[0041] It should be noted that the thickness of the first clamping plate 1 is the dimension along the axial direction of the first through hole 101; the thickness of the second clamping plate 2 is the dimension along the axial direction of the second through hole 201.

[0042] In some feasible embodiments of this utility model, the first clamping plate 1 and the second clamping plate 2 are rectangular plates, which are convenient for the operator to use.

[0043] In some feasible embodiments of this utility model, the center of the first through hole 101 coincides with the center point of the first clamping plate 1; the center point of the second through hole 201 coincides with the center point of the second clamping plate 2. That is, the first through hole 101 is located in the middle of the first clamping plate 1, and the second through hole 201 is located in the middle of the second clamping plate 2. When the dough sample is placed between the through holes for testing, the central position of the through holes ensures that the clamping plates are subjected to uniform force in all directions during clamping, effectively avoiding sample displacement or testing errors caused by uneven force. At the same time, the centrally located through holes make it easy for operators to quickly and accurately locate the position of the dough sample without repeated adjustments and calibrations, greatly improving testing efficiency.

[0044] In some feasible embodiments of this utility model, both the first clamping plate 1 and the second clamping plate 2 have a long side and a wide side. Mounting holes 4 are provided near the four corners of both the first clamping plate 1 and the second clamping plate 2. Fasteners 3 are correspondingly disposed within the mounting holes 4. The clamping of the first clamping plate 1 and the second clamping plate 2 is achieved by the fasteners 3 passing through the mounting holes 4. The mounting holes 4 distributed at the four corners and the fasteners 3 ensure that the clamping plates are subjected to uniform force during clamping, avoiding deformation of the clamping plates or damage to the samples caused by localized stress concentration. This ensures stable and reliable force transmission during testing and improves the accuracy of the test data.

[0045] In some feasible embodiments of this utility model, the distance between the center of the mounting hole 4 and its nearest long edge is the first distance, and the distance between the center of the mounting hole 4 and its nearest wide edge is the second distance, with the first and second distances being equal. This equidistant arrangement ensures that the clamping plate will not twist or deform due to uneven force during tightening, effectively avoiding test errors caused by clamping plate deformation. The symmetrical layout of the mounting holes 4 reduces installation difficulty; operators do not need to repeatedly compare and adjust the position, enabling them to quickly and accurately install the fasteners 3, significantly improving testing efficiency.

[0046] In some feasible embodiments of this utility model, the diameters of the first through hole 101 and the second through hole 201 are equal and are 38-42mm, more preferably 40mm. The length of the first clamping plate 1 and the width of the second clamping plate 2 are 100mm and 90mm respectively. Of course, the above dimensions can also be adjusted adaptively according to requirements.

[0047] In summary, the test platform for dough extensibility testing provided by this utility model can ensure that the sample does not slip or break at the clamping position during measurement, and can accurately characterize the extensibility of soft dough samples such as wonton wrappers. It is simple to operate and ensures measurement accuracy.
