Description

Technical Field

[0001] This utility model relates to the field of sample clamping technology, and in particular to a sample clamping mechanism for testing tea polyphenols in textile fibers. Background Technology

[0002] With the textile industry's continuous transformation towards functionality and intelligence, the research and application of functional textile materials are becoming increasingly widespread. Among them, functional textile fibers containing tea polyphenols, due to their excellent properties such as anti-oxidation, antibacterial, and UV resistance, have shown great potential in fields such as health apparel and medical textiles. To ensure product quality and performance meet standards, accurately detecting the tea polyphenol content in textile fibers has become a core requirement in production, research and development, and quality supervision. However, in the existing technology, the clamping mechanism of the existing detection device uses a spring clamp structure. The clamping force of the sample clamping mechanism fluctuates significantly with the sample thickness. When clamping smaller parts, the spring clamp is difficult to provide sufficient clamping force, causing the sample to slide and the detection position to deviate from the instrument window. This results in unstable detection signals and poor data repeatability. When detecting thicker samples, the spring deformation is too large, and the clamping force far exceeds the sample's tolerance range. This can easily cause fiber breakage or structural damage, altering the distribution and release path of tea polyphenols in the fibers and affecting the detection accuracy. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a sample clamping mechanism for detecting tea polyphenols in textile fibers.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a textile fiber tea polyphenol detection sample clamping mechanism, comprising: A clamping frame, on which a support plate is slidably connected; An adjustable clamping structure includes a lower pressure plate slidably connected within a clamping frame, a transmission plate slidably connected to the lower pressure plate, a transmission rod slidably connected to the transmission plate, an inner sliding frame fixedly connected to the transmission rod, a support shaft fixedly connected to the inner sliding frame, a rotating shaft rotatably connected to the support shaft, an inner buckle plate rotatably connected to the rotating shaft, a support rod fixedly connected to the transmission plate, and a sliding frame slidably connected to the support rod.

[0005] In a preferred embodiment, two rotating shafts are provided, which are rotatably connected to both ends of the inner buckle plate. The inner buckle plate is rotatably connected to the bottom of the transmission plate via the rotating shafts. A motor is fixedly connected to the clamping frame, and a lead screw is fixedly connected to the output end of the motor. The lead screw is threadedly connected to the lower pressure plate.

[0006] Using the above technical solution: when in use, the rotation of the electric screw of the motor causes the lower pressure plate to be driven to move vertically within the clamping frame.

[0007] In a preferred embodiment, the transmission plate has an inclined groove, the transmission rod is slidably connected in the inclined groove of the transmission plate, and a limit rod is fixedly connected to the lower pressure plate, the limit rod being slidably connected in the clamping frame.

[0008] The above technical solution is adopted so that when the transmission rod slides in the inclined groove during use, it can drive the transmission plate to move towards the side closer to the lower pressure plate. The limiting rod supports the lower pressure plate to prevent it from being driven to rotate by the lead screw.

[0009] In a preferred embodiment, two inner sliding frames are provided, and a spring is fixedly connected between the two inner sliding frames.

[0010] By adopting the above technical solution, the spring on the inner slide frame can prevent the inner slide frame from sliding too much during use.

[0011] In a preferred embodiment, the clamping frame has a slot, and the support shaft is slidably connected to the slot on the clamping frame.

[0012] The above technical solution allows the slots on the clamping frame to guide the sliding of the support shaft during use.

[0013] In a preferred embodiment, the support plate has an opening, and the transmission rod is slidably connected in the opening of the support plate.

[0014] The above technical solution is adopted: during use, openings are made in the support plate to prevent the transmission rod from falling off.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows: The sliding engagement between the inclined groove on the transmission plate and the transmission rod in this invention allows for automatic adjustment of the clamping force transmission path based on sample thickness. When the sample thickness changes, the upward lifting of the sliding frame driven by the support rod balances the displacement of the transmission plate. Thinner samples require a smaller lifting amount, resulting in a shorter sliding distance of the transmission rod within the inclined groove and a gentler increase in clamping force. Thicker samples trigger a larger lifting amount, causing the transmission rod to push the transmission plate to slide inwards towards the clamping frame. Through the linkage between the support shaft and the rotating shaft, the inner clamping plate synchronously compresses the sample, achieving an adaptive effect where the clamping force increases more uniformly with increasing thickness. This solves the problem that traditional spring clamps cannot adapt to samples of different thicknesses. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5 As shown, a sample clamping mechanism for detecting tea polyphenols in textile fibers includes: Clamping frame 1, with a support plate 11 slidably connected to clamping frame 1; The adjustable clamping structure 2 includes a lower pressure plate 23 slidably connected within the clamping frame 1, a transmission plate 211 slidably connected to the lower pressure plate 23, a transmission rod 212 slidably connected to the transmission plate 211, an inner sliding frame 29 fixedly connected to the transmission rod 212, a support shaft 214 fixedly connected to the inner sliding frame 29, a rotating shaft 28 rotatably connected to the support shaft 214, an inner buckle plate 26 rotatably connected to the rotating shaft 28, a support rod 213 fixedly connected to the transmission plate 211, and a sliding frame 24 slidably connected to the support rod 213.

[0024] The inclined groove on the transmission plate 211 of this utility model and the sliding engagement of the transmission rod 212 can automatically adjust the transmission path of the clamping force according to the sample thickness. When the sample thickness changes, the upward lifting of the sliding frame 24 driven by the support rod 213 is balanced with the displacement of the transmission plate 211. Thin samples correspond to a smaller lifting amount, and the sliding distance of the transmission rod 212 in the inclined groove is short, resulting in a gradual increase in clamping force. Thicker samples trigger a larger lifting amount. The transmission rod 212 pushes the transmission plate 211 to slide inward to the clamping frame 1. Through the linkage of the support shaft 214 and the rotating shaft 28, the inner clamping plate 26 synchronously squeezes the sample, achieving an adaptive effect where the clamping force increases more uniformly as the thickness increases. This solves the problem that the traditional spring 210 clamp cannot adapt to samples of different thicknesses.

[0025] Furthermore, such as Figures 1 to 5 As shown, there are two rotating shafts 28, which are rotatably connected to both ends of the inner buckle plate 26. The inner buckle plate 26 is rotatably connected to the bottom of the transmission plate 211 through the rotating shafts 28. A motor 21 is fixedly connected to the clamping frame 1. A lead screw 22 is fixedly connected to the output end of the motor 21. The lead screw 22 is threadedly connected to the lower pressure plate 23. When in use, the motor 21 rotates the lead screw 22, causing the lower pressure plate 23 to be driven to move vertically within the clamping frame 1.

[0026] A slanted groove is provided on the transmission plate 211, and the transmission rod 212 is slidably connected in the slanted groove on the transmission plate 211. A limit rod 25 is fixedly connected to the lower pressure plate 23. The limit rod 25 is slidably connected in the clamping frame 1. When the transmission rod 212 slides in the slanted groove, it can drive the transmission plate 211 to move closer to the lower pressure plate 23. The limit rod 25 supports the lower pressure plate 23 to prevent it from being rotated by the lead screw 22.

[0027] There are two inner sliding frames 29, and a spring 210 is fixedly connected between the two inner sliding frames 29. When in use, the spring 210 on the inner sliding frame 29 can prevent the inner sliding frame 29 from sliding too much.

[0028] The clamping frame 1 has a slot, and the support shaft 214 is slidably connected in the slot on the clamping frame 1. When in use, the slot on the clamping frame 1 can guide the sliding of the support shaft 214.

[0029] The support plate 11 has an opening, and the transmission rod 212 is slidably connected in the opening on the support plate 11. In use, the opening on the support plate 11 prevents the transmission rod 212 from falling off.

[0030] Working principle: like Figure 1-5As shown, when in use, the sample is placed on the sliding frame 24. By starting the motor 21, the motor 21 drives the lead screw 22 to rotate, causing the lower pressure plate 23 to slide down and press against the sample on the sliding frame 24, completing the initial clamping. At this time, the transmission rod 212 does not contact the transmission plate 211. As the lead screw 22 continues to rotate, the lower pressure plate 23 causes the support rod 213 to slide further down. At this time, the clamping force increases, causing the support rod 213 to drive the support plate 11 to slide down. The support plate 11 contacts the transmission rod 212, and at the same time, the support plate 11 will squeeze the inner buckle plate 26, causing the inner buckle plate 26 to drive the rotating shaft 28 to move. This causes the rotating shaft 28 to drive the support shaft 214 to clamp and slide on the clamping frame 1, causing the transmission rod 212 to clamp and move inward on the transmission plate 211, causing the transmission plate 211 to slide closer to the clamping frame 1. The support rod 213 is driven to squeeze the sliding frame 24, causing the sliding frame 24 to rise upward and increase the squeezing force.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
