Technical Field
[0001] This utility model belongs to the technical field of pretreatment test technology for polyester resin samples for thermosetting powder coatings. Specifically, this utility model relates to a sample bottle. Background Technology
[0002] Thermosetting polyester resins for powder coatings are a class of mixtures obtained by dehydration and polycondensation of polybasic acids (terephthalic acid, isophthalic acid, adipic acid, etc.) and polyols (neopentyl glycol, ethylene glycol, trimethylolpropane, etc.) under the catalysis of catalysts (tin compounds, etc.), and the addition of appropriate functionalizing agents. Thermosetting polyester resins are the main raw materials for powder coatings. They are mixed with curing agents, fillers, pigments, and other additives in specific proportions, sprayed onto the substrate surface, and then cured by heat to form a powder coating that provides both decoration and protection to the substrate. As one of the important raw materials for powder coatings, providing accurate polyester resin parameters is particularly important. These parameters include acid value, viscosity, softening point, and glass transition temperature, as these indicators affect the formulation, process conditions, and storage stability of the powder coating.
[0003] In the testing of this polyester resin, even slight carelessness can lead to errors in the test results. For example, during the glass transition temperature (GVT) test, touching the sample with your hand may cause the measured GVT to be several degrees lower than expected. Thermosetting powder coatings have requirements for the particle size and sheet thickness of the polyester resin. Since this polyester resin is in sheet form, the sample amount for glass transition temperature testing is generally around 10mg. Furthermore, an excessively large sample will affect the contact between the sample and the crucible, delaying heat conduction and thus affecting the accuracy of the glass transition temperature measurement. Therefore, the sample particle size must not be too large during the glass transition temperature testing of polyester resin. In the acid value testing of polyester resin, the principle for weighing and adding the sample is to add more initially and then less later. Since the sample is in sheet form, it is difficult to control the addition of small amounts of sample later, which may result in over-weighing and exceeding the specified limits, leading to excessive errors.
[0004] Chinese patent CN206103950U disclosed a sample bottle on April 19, 2017, including a cap and a body. The body includes a bottom, a mouth, and a straight cylindrical portion disposed between the bottom and the mouth. The angle between the folded edge of the mouth and the vertical plane of the straight cylindrical portion is not less than 65 degrees. The upper edge of the folded edge is the mouth rim of the bottle. However, this sample bottle cannot solve the problem of adjusting the sample particle size and cannot improve the accuracy of weighing. Utility Model Content
[0005] The present invention aims to provide a sample bottle with adjustable sample particle size and improved weighing accuracy, in order to solve the problems of excessively large sample particle size and inaccurate weighing.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A sample bottle includes a bottle body and a cap disposed on the top of the bottle body, wherein the cap is provided with an adjustment mechanism.
[0008] The adjustment mechanism includes a grinding core, an adjustment block, a threaded rod, and a spring. The adjustment block and the grinding core are sequentially arranged on one end of the threaded rod, and the spring is arranged on the outer wall of the other end of the threaded rod. The spring and the grinding core are in contact. The end of the threaded rod with the spring is connected to the bottom of the bottle cap.
[0009] The bottom of the bottle cap is provided with a grinding seat, the grinding seat is connected to a support column, the support column is connected to a threaded rod, the grinding seat is provided with a support base, the support base is connected to the inner wall of the bottle cap, and the grinding seat is connected to the top of the bottle body.
[0010] The support base is provided with a grinding cavity, and the grinding base is provided with a through hole communicating with the grinding cavity. The support column extends into the grinding cavity, and the grinding core is located inside the grinding cavity.
[0011] The grinding chamber is a stepped hole, which includes a first circular hole and a second circular hole. The diameter of the first circular hole is smaller than that of the second circular hole. The support column extends into the first circular hole, and the grinding core is located in the second circular hole. A shim is provided between the grinding core and the adjusting block.
[0012] The bottle cap has a funnel at the top, and the funnel and the bottle cap are connected by threads. The bottle body has a base at the bottom.
[0013] The bottle body and the grinding seat are threaded together.
[0014] The grinding core is conical, the adjusting block is conical, and the width of the grinding core is greater than the width of the adjusting block.
[0015] The grinding core is provided with a spiral structure, and the adjusting block is provided with a spiral structure.
[0016] The bottle body is cylindrical, and the grinding base is cylindrical.
[0017] The technical advantages of this utility model are as follows: The sample bottle provided by this utility model rotates the adjusting mechanism by rotating the grinding base. The bottle cap of the sample bottle is equipped with a funnel. The bottle body and the cap of the sample bottle are inverted. The sample is poured out from the funnel after grinding, which reduces the sample particle size and ensures that the sample particle size meets the testing requirements. It can also pour out a small amount of sample, making the weighing more accurate. The sample is not in contact throughout the process, which improves the accuracy of the test. By only rotating the grinding base, the complex process of sample preparation is reduced and the efficiency of sample testing is improved. Attached Figure Description

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this utility model, and to facilitate its implementation.
[0024] like Figure 1 As shown, a sample bottle includes a bottle body 1 and a bottle cap 2 located on top of the bottle body 1. The bottle cap 2 has an adjustment mechanism 3 inside. The bottle body 1 is made of glass. When not sampling, the bottle body 1 is covered with an ordinary steel cap. When sampling, the ordinary steel cap is opened and the bottle cap 2 with the adjustment mechanism 3 inside is installed.
[0025] like Figure 1 and Figure 2 As shown, the adjusting mechanism 3 includes a grinding core 4, an adjusting block 5, a threaded rod 6, and a spring 7. The adjusting block 5 and the grinding core 4 are sequentially arranged on one end of the threaded rod 6, and the spring 7 is arranged on the outer wall of the other end of the threaded rod 6. The spring 7 is in contact with the grinding core 4. The end of the threaded rod 6 with the spring 7 is connected to the bottom of the bottle cap 2. The adjusting mechanism 3 is located inside the bottle body 2 near the bottom. The grinding core 4 is a ceramic product, and the grinding core 4 is threadedly connected to the threaded rod 6. The adjusting block 5 is also threadedly connected to the threaded rod 6, and the spring 7 is sleeved on the outer wall of the threaded rod 6.
[0026] The bottle cap 2 has a grinding seat 8 at its bottom, which is connected to a support column 9. The support column 9 is connected to a threaded rod 6. A support base 10 is provided on the grinding seat 8, which is connected to the inner wall of the bottle cap 2. The grinding seat 8 is also connected to the top of the bottle body 1. The grinding seat 8 at the bottom of the bottle cap 2, connected to the support column 9, and the threaded rod 6 are connected to the support column 9, allows the grinding seat 8 to rotate at the bottom of the bottle cap 2, thereby rotating the entire regulator 3. The support base 10 is located inside the bottle cap 2 housing and serves as a limit, preventing the regulator 3 from shifting position and restricting the vertical movement of the grinding seat 8 during rotation. Before sampling, determine the required particle size. Remove the funnel 14 from the top of the bottle cap 2. Move the adjusting block 5 and grinding core 4 downwards, pressing the spring 7. This reduces the gap between the grinding core 4 and the support base 10, resulting in a smaller particle size after grinding. Move the adjusting block 5 and grinding core 4 upwards, stretching the spring 7. This increases the gap between the grinding core 4 and the support base 10, resulting in a larger particle size after grinding. After adjustment, reinstall the funnel 14. When installing the bottle cap 2, the top of the bottle body 1 is threaded to the grinding base 8, ensuring that rotating the bottle body 1 drives the rotating grinding base 8. At this point, the rotating grinding base 8 experiences greater force, making the process slightly easier.
[0027] The support base 10 is provided with a grinding chamber 12, and the grinding base 8 is provided with a through hole 13 communicating with the grinding chamber 12. The support column 9 extends into the grinding chamber 12, and the grinding core 4 is located inside the grinding chamber 12. The support base 10 is provided with a grinding chamber 12, and the grinding base 8 is provided with a through hole 13. The through hole 13 is circular, and multiple sets of through holes 13 are provided. The sample passes through the through holes 13 sequentially from the inside of the bottle body 1, and then enters the grinding chamber 12. After being ground in the grinding chamber 12, it enters the top of the bottle cap 2.
[0028] The grinding chamber 12 is a stepped hole, including a first circular hole 16 and a second circular hole 17. The diameter of the first circular hole 16 is smaller than that of the second circular hole 17. The support column 9 extends into the first circular hole 16, and the grinding core 4 is located in the second circular hole 17. A shim 11 is provided between the grinding core 4 and the adjusting block 5. The grinding chamber 12 is a stepped hole, including a first circular hole 16 and a second circular hole 17. The diameter of the first circular hole 16 is smaller than that of the second circular hole 17. The first circular hole 16 is a smaller circular hole, and the second circular hole 17 is a larger circular hole. The support column 9 extends into the first circular hole 16, and the grinding core 4 is located in the second circular hole 17. The shim 11 is an anti-wear shim, used to prevent direct contact between the ceramic grinding core 4 and the adjusting block 5 during the grinding process, preventing friction from causing adhesion or damage, protecting the structural integrity of the grinding core 4, and extending its service life.
[0029] like Figure 1 and Figure 3As shown, the bottle cap 2 has a funnel 14 on top, and the funnel 14 and the bottle cap 2 are connected by threads. The bottle body 1 has a base 15 at the bottom. The funnel 14 on top of the bottle cap 2 is made of stainless steel. The funnel 14 can guide the sample into the designated container. The slender tubular design of the funnel 14 also makes it easy to control the sample flow rate and prevent over-weighing and inaccurate results that may affect the experiment. The base 15 is cylindrical, which provides stability when placed and facilitates the rotation of the bottle body 1.
[0030] The bottle body 1 and the grinding seat 8 are threaded together. The grinding seat 8 is located at the bottom of the bottle cap 2. The inner wall of the bottle body 1 is provided with internal threads and the outer wall of the grinding seat 8 is connected with external threads. After the bottle body 1 and the grinding seat 8 are threaded together, the bottle body 1 extends into the bottle cap 2, ensuring that the rotation of the bottle body 1 drives the grinding seat 8 to rotate.
[0031] The grinding core 4 is conical, and the adjusting block 5 is also conical. The width of the grinding core 4 is greater than the width of the adjusting block 5. The grinding core 4 is positioned below the adjusting block 5. The larger width of the grinding core 4 results in a smaller gap between the grinding core 4 and the support base 10, which facilitates grinding of the sample as it passes through them.
[0032] The grinding core 4 and the adjusting block 5 are equipped with spiral structures. The spiral structures on both the grinding core 4 and the adjusting block 5 increase friction during grinding, thereby further improving the grinding effect.
[0033] The bottle body 1 is cylindrical, and the grinding base 8 is cylindrical. The cylindrical bottle body 1 and the grinding base 8 are suitable for rotation during grinding.
[0034] The working principle of this utility model is as follows: A sample bottle includes a bottle body 1 and a bottle cap 2 located on the top of the bottle body 1. An adjustment mechanism 3 is provided inside the bottle cap 2. The adjustment mechanism 3 includes a grinding core 4, an adjusting block 5, a threaded rod 6, and a spring 7. The spring 7 is sleeved on one end of the outer wall of the threaded rod 6. The grinding core 4 and the threaded rod 6 are connected at the middle, and the adjusting block 5 is connected to the other end of the threaded rod 6. A gasket 11 is provided between the grinding core 4 and the adjusting block 5. A grinding seat 8 is provided at the bottom of the bottle cap 2. The grinding seat 8 is connected to a support column 9, which is connected to the threaded rod 6. A support base 10 is provided on the grinding seat 8 and is located inside the shell of the bottle cap 2. The support base 10 has a grinding chamber 12, and the grinding seat 8 has a through hole 13. A funnel 14 is provided at the top of the bottle cap 2, and a base 15 is provided at the bottom of the bottle body 1. The bottle body 1 and the grinding seat 8 are threaded together. The grinding core 4 and the adjusting block 5 have spiral structures. Before sampling, remove the funnel 14 from the bottle cap 2, rotate the adjusting block 5, tighten the spring 7, and adjust the distance between the grinding core 4 and the support column 9. During sampling, install the bottle cap 2 with the adjusting mechanism 3 onto the bottle body 1, invert the bottle body 1 and bottle cap 2, and rotate the bottle body 1 and grinding seat 8. The grinding seat 8 drives the threaded rod 6 on the support column 9 to rotate, and the rotation of the threaded rod 6 drives the grinding core 4, the gasket 11 and the adjusting block 5 to rotate. The sample in the bottle body 1 enters the grinding chamber 12 of the support seat 10 through the through hole 13 on the grinding seat 8, and after grinding, enters the funnel 14 through the gap between the grinding core 4 and the support seat 10. From the funnel 14, it slowly enters the designated container, reducing the sample particle size to meet the testing requirements, slowing down the pouring speed, and achieving smaller sample pours for more accurate weighing.
