Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of starch production equipment, and in particular to a sampling device for testing potato starch. Background Technology
[0002] Potato starch plays an important and diverse role in many industries, including the food industry (using it as a thickener, gelling agent, and binder to improve the texture and mouthfeel), the paper industry (strengthening paper and improving surface properties), the textile industry (as a sizing component to aid weaving), and the pharmaceutical industry (as a pharmaceutical excipient). Sampling equipment is needed to test potato starch to ensure sample representativeness, testing precision and accuracy, compliance with quality control and standards, and to improve work efficiency and safety.
[0003] Sampling equipment for potato starch testing generally consists of sampling components, a power unit, and auxiliary devices. This potato starch sampling equipment uses manual or power-driven sampling heads, tubes, spoons, and other components to sample solid and liquid starch in a corresponding manner. It uses stirring paddles and transmission components to achieve sample mixing and dispersion. It utilizes various principles such as mechanical scale or electronic induction depth control, vibrators or ventilation channels to prevent clogging, and nozzles and cleaning brushes to achieve sampling and related auxiliary functions.
[0004] Existing sampling equipment for potato starch testing often fails to automate the dispersion of starch, as many tests require high sample homogeneity. For example, in the chemical property testing of starch, such as detecting reducing sugar content or starch content itself, if the starch is not dispersed, reagents cannot fully contact and react with the starch during chemical analysis. For instance, when using chemical titration to detect reducing sugar content, lumpy starch can cause uneven reagent penetration, preventing the internal starch from fully participating in the reaction, thus leading to inaccurate results and reduced testing precision. Therefore, this paper proposes a sampling device for potato starch testing to address these issues. Utility Model Content

[0031] 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.
[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a sampling device for potato starch testing, comprising a main body 1 as the core frame of the entire sampling device, made of sturdy and corrosion-resistant aluminum alloy, which provides a stable support structure for the internal components, ensuring that the device is not easily deformed or damaged during long-term use. A rotating shell 3 is rotatably connected to one side of the main body 1. The rotating shell 3 can rotate flexibly, and its rotating connection part uses high-precision bearings, resulting in smooth rotation and low noise, facilitating opening, closing, or angle adjustment during specific operations.
[0033] The main body 1 has a drive assembly internally fixedly connected to drive the parts. The core of the drive assembly is a motor 4, which is a DC motor with appropriate power and stable operation. Its bottom is fixedly connected to the inside of the main body 1 by high-strength bolts, ensuring that the motor 4 will not shift during operation. A rotating disk 5 is fixedly connected to the top of the motor 4. The rotating disk 5 is made of stainless steel, which has good strength and wear resistance, and can stably withstand the force transmitted by the connecting rod 6 and drive it to rotate. The bottom of the connecting rod 6 is rotatably connected to the inside of the rotating disk 5. When the motor 4 starts, the motor 4 drives the rotating disk 5, causing the rotating disk 5 to rotate at high speed.
[0034] A linkage rod 7 is fixedly connected to the outer side of the connecting rod 6. The linkage rod 7 is made of a lightweight and sturdy alloy material, which can effectively transmit power and its own weight will not put too much burden on the operation of the device. A limiting box 8 is fixedly connected to the side of the linkage rod 7 away from the connecting rod 6. The limiting box 8 is a cuboid structure, and a limiting frame 12 is fixedly connected inside it. The limiting frame 12 is made of metal and has been treated with anti-rust. It can play a good role in limiting and supporting the tray 13. The tray 13 is slidably connected inside the limiting frame 12. The tray 13 is made of food-grade plastic material, with a smooth surface that is easy to clean. It can directly contact potato starch to ensure that the starch is not contaminated.
[0035] A sliding block 9 is fixedly connected to the bottom of the limiting box 8. The sliding block 9 is made of wear-resistant engineering plastic, and a slide rail 11 is slidably connected to its outer side. The slide rail 11 is made of metal and its surface is finely polished, resulting in low friction. Limiting blocks 10 are fixedly connected to both sides of the sliding block 9. The outer side of the limiting blocks 10 is slidably connected to the inside of the slide rail 11. Through this structural design, the limiting box 8 can only slide back and forth along the slide rail 11. When the rotating disk 5 rotates, the connecting rod 6 will also rotate with the rotating disk 5, and the linkage rod 7 connected to the outer end of the connecting rod 6 will also rotate with the rotating disk 5. This causes the linkage rod 7 to drive the limiting box 8 to slide backward. Under the guidance of the slide rail 11, the limiting box 8 can swing back and forth smoothly, thereby causing the potato starch inside the tray 13 to disperse. This prevents the potato starch from piling up when the sampling device places it inside the tray 13, ensuring the uniformity and accuracy of the sampling.
[0036] Reference Figure 1 , Figure 2 , Figure 4 A control panel 2 is fixedly connected to the top of the main body 1. The control panel 2 has clear operation buttons and a display screen, making it convenient for operators to control and set parameters for components such as the motor 4. A power cord 14 is fixedly connected to one side of the main body 1. The power cord 14 uses a rubber outer sheath with good insulation and bend resistance to wrap the internal copper core wire, ensuring stable current transmission and safe use. The other end of the power cord 14 is rotatably connected to a take-up reel 15. The take-up reel 15 is made of plastic and has a hole on its top. A limiting component for restricting the power cord 14 is fixedly connected to the top of the take-up reel 15.
[0037] The limiting component includes a second limiting block 16, the bottom of which is fixedly connected to the top of the take-up reel 15. A rotating block 17 is rotatably connected inside the second limiting block 16. The rotating block 17 rotates flexibly, and a rotating plate 18 is rotatably connected to its bottom. A spring 20 is fixedly connected to the side of the rotating plate 18 away from the rotating block 17. The spring 20 has a suitable elastic coefficient, and its other end is slidably connected to the top of the take-up reel 15. A limiting post 19 is fixedly connected to the side of the rotating plate 18 away from the rotating block 17, and the outer side of the limiting post 19 is slidably connected inside the hole.
[0038] Under normal circumstances, the rotating plate 18 is restricted to the top of the take-up reel 15 by the rotating block 17, thus confining the power cord 14 wound inside the take-up reel 15. When it is necessary to test the potato starch, the restriction of the rotating plate 18 can be removed by rotating the rotating block 17, thereby causing the spring 20 to spring up the rotating plate 18, which in turn causes the limiting post 19 to leave the inside of the take-up reel 15. At this time, the power cord 14 can be taken out from the inside of the take-up reel 15, which facilitates the storage and use of the power cord 14 and prevents it from being scattered at will when the device is not in use, thus avoiding damage or safety hazards.
[0039] Working principle: When staff need to sample and test potato starch, they can place the potato starch into the tray 13 using a sampling device. Then, the motor 4 is started, driving the rotating disk 5. A connecting rod 6 rotates on top of the rotating disk 5, which in turn drives the linkage rod 7. Because the rotating disk 5 rotates, the connecting rod 6 also rotates with it, and the linkage rod 7 connected to the outer end of the connecting rod 6 rotates with the rotating disk 5. This causes the linkage rod 7 to slide the limiting box 8 backward. A sliding block 9 is connected to the bottom of the limiting box 8, which slides inside the slide rail 11. The slide rail 11 creates a back-and-forth swaying effect on the limiting box 8, causing the potato starch inside the tray 13 to disperse, preventing the potato starch from piling up when the sampling device places it inside the tray 13.
[0040] When potato starch needs to be tested, the restriction of the rotating plate 18 can be removed by rotating the rotating block 17, so that the spring 20 will spring the rotating plate 18 up, thereby causing the limiting post 19 to leave the inside of the take-up reel 15. Under normal circumstances, the rotating plate 18 is restricted to the top of the take-up reel 15 by the rotating block 17, so that the power cord 14 wound inside the take-up reel 15 can be restricted inside. When the rotating plate 18 is rotated, the power cord 14 can be taken out from the inside of the take-up reel 15.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
