Description

Technical Field

[0001] This utility model mainly relates to the technical field of sample dissolution equipment for food testing, specifically a sample dissolution device for food testing. Background Technology

[0002] Food inspection and testing is a discipline that studies and evaluates the quality and changes of food. Based on some basic theories of physics, chemistry, and biochemistry and various technologies, it inspects the quality of food raw materials, auxiliary materials, semi-finished products, finished products and by-products in accordance with established technical standards, such as international and national food hygiene / safety standards, to ensure that the products are of qualified quality.

[0003] Existing food testing sample dissolution methods involve placing the sample and solvent into a mixing tank and then stirring them using a stirring mechanism. However, most existing dissolution stirring mechanisms are fixedly installed, and the sample tends to accumulate around the inner wall of the mixing tank, resulting in poor stirring effect and low sample dissolution efficiency. Furthermore, the stirring rod is inconvenient to disassemble, making it difficult to clean and maintain, which inconveniences the user. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a sample dissolving device for food testing. This invention features a simple structure and ease of use. A horizontal transmission mechanism drives two connecting blocks to move horizontally, which in turn drives the first stirring rod to move horizontally, thus stirring different areas within the dissolving container and increasing sample fluidity. The extension and retraction of the second telescopic rod causes the second stirring rod to move up and down, stirring the sample at the edge of the dissolving container, thereby improving the dissolving efficiency and effectiveness. Furthermore, both the first and second connecting shafts are detachably connected to the connecting sleeve, facilitating replacement and maintenance of the first and second connecting shafts, thus simplifying sample dissolving.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A sample dissolving device for food testing includes a base. Vertical rods are installed at the four corners of the base's top surface. The top ends of the four vertical rods are connected by a top plate. Two first telescopic rods, distributed laterally, are installed on the top plate. The bottom ends of the two first telescopic rods are connected by a connecting plate. A horizontal transmission mechanism is installed on the bottom surface of the connecting plate. Two connecting blocks, distributed laterally, are installed on the horizontal transmission mechanism. A stirring motor is installed on the bottom surface of each connecting block. A first connecting sleeve is installed at the bottom end of each stirring motor shaft. A first connecting shaft is detachably installed within each first connecting sleeve. Several first stirring rods are installed on each first connecting shaft. A rotary motor is installed on the top surface of the base.

Second telescopic rods are installed on both the front and rear sides of the bottom surface of the connecting plate. A horizontal plate is installed at the bottom end of each second telescopic rod. A second connecting sleeve is installed on the bottom surface of each horizontal plate. A second connecting shaft is detachably installed within each second connecting sleeve. Several second stirring rods are installed on each second connecting shaft.

[0007] Furthermore, the horizontal transmission mechanism includes a transmission motor and two left and right distributed fixed plates. The fixed plates are connected to the connecting plates. The transmission motor is mounted on one of the fixed plates. A lead screw is installed at one end of the shaft of the transmission motor. One end of the lead screw is rotatably connected to the other fixed plate. Opposite threads are opened at both ends of the lead screw. Both connecting blocks are threaded with the lead screw.

[0008] Furthermore, each of the inner walls of the first connecting sleeve and the inner walls of the second connecting sleeve is equipped with arc-shaped clamps by springs, and the arc-shaped clamps respectively contact and cooperate with the corresponding first connecting shaft and second connecting shaft.

[0009] Furthermore, a fastening bolt is installed on the front of each of the connecting sleeves and the front of each of the second connecting sleeves, and one end of the fastening bolt can contact and engage with the corresponding first connecting shaft and second connecting shaft.

[0010] Furthermore, several evenly distributed support rods are installed on the top surface of the base, and the top of each support rod slides in contact with the bottom surface of the placement plate.

[0011] Furthermore, several evenly distributed arc-shaped fastening plates are installed on the top surface of the placement plate, and all of the arc-shaped fastening plates are in contact with and fitted with the dissolving tank.

[0013] Compared with the existing technology, the beneficial effects of this utility model are:

[0014] This invention features a simple structure and is easy to use. A horizontal transmission mechanism drives two connecting blocks to move horizontally, which in turn drives the first stirring rod to move horizontally, thus stirring different areas within the dissolving container and increasing sample fluidity. The extension and retraction of the second telescopic rod allows the second stirring rod to move up and down, stirring the sample at the edge of the dissolving container, thereby improving the dissolution efficiency and effect. Furthermore, both the first and second connecting shafts are detachably connected to the connecting sleeve, facilitating replacement and maintenance of the first and second connecting shafts, thus providing convenience for sample dissolution.

[0022] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0023] like Figure 1-6As shown, the food testing sample dissolving device of this utility model includes a base 1, with vertical rods 2 installed at the four corners of the top surface of the base 1. The top ends of the four vertical rods 2 are connected by a top plate 3. Two telescopic rods 4 are installed on the top plate 3. By extending and retracting the telescopic rods 4, the connecting plate 5 can be moved up and down, thereby moving the first connecting shaft 9 and the first stirring rod 10 up and down, so as to facilitate the removal of the dissolving tank 13 after dissolving.

[0024] The two telescopic rods 4 are connected at their bottom ends by a connecting plate 5. A horizontal transmission mechanism is installed on the bottom surface of the connecting plate 5. Two connecting blocks 6 are installed on the horizontal transmission mechanism. The horizontal transmission mechanism can drive the connecting blocks 6 to move horizontally, thereby driving the stirring motor 7, the first connecting shaft 9 and the first stirring rod 10 to move horizontally. This allows for stirring at different positions inside the dissolving tank 27, thereby increasing the fluidity of the sample in the dissolving tank 27 and improving the dissolution efficiency of the sample.

[0025] Each connecting block 6 has a stirring motor 7 mounted on its bottom surface. Each stirring motor 7 has a connecting sleeve 8 mounted on its bottom shaft. Each connecting sleeve 8 can be detachably installed with a first connecting shaft 9. Several first stirring rods 10 are mounted on each first connecting shaft 9. The top surface of the base is provided with a dissolving tank 27. A discharge pipe is installed on one side of the dissolving tank 27, and a control valve is installed on the discharge pipe. When the two stirring motors 7 are working, they work in opposite directions, which drives the two first stirring shafts 9 to rotate in opposite directions, thereby increasing the fluidity of the sample in the dissolving tank 27 and further improving the solution efficiency.

[0026] A rotary motor 11 is installed on the top surface of the base 1. A placement plate 12 is installed on the top of the rotating shaft of the rotary motor 11. A dissolving tank 27 is installed on the top surface of the placement plate 12. When the rotary motor 11 is working, it can drive the placement plate 12 and the dissolving tank 27 to rotate, thereby driving the sample to rotate. This facilitates the first stirring rod 10 and the second stirring rod 17 to fully stir the sample in the dissolving tank 27, further increasing the flow of the sample in the solution.

[0027] The connecting plate 5 has a second telescopic rod 13 installed on both the front and rear sides of its bottom. Each second telescopic rod 13 has a horizontal plate 14 installed at its bottom end. Each horizontal plate 14 has a second connecting sleeve 15 installed on its bottom surface. A second connecting shaft 16 can be detachably installed in each second connecting sleeve 15. Several second stirring rods 17 are installed on each second connecting shaft 16. By extending and retracting the second telescopic rods 13, the horizontal plate 14 can be moved up and down. The movement of the horizontal plate 14 can drive the second connecting shaft 16 and the second stirring rods 17 to move up and down, thereby changing the position of the second stirring rods 17 in the dissolving tank 27, thereby further increasing the stirring of the sample and thus increasing the dissolution of the sample.

[0028] Specifically, the horizontal transmission mechanism includes a drive motor 18 and two left-right distributed fixed plates 19. The fixed plates 19 are connected to the connecting plate 5. The drive motor 18 is mounted on one of the fixed plates 19. A lead screw 20 is installed at one end of the shaft of the drive motor 18. One end of the lead screw 20 is rotatably connected to the other fixed plate 19. The two ends of the lead screw 20 have opposite threads. Both connecting blocks 6 are threadedly engaged with the lead screw 20. When the drive motor 18 operates, it drives the lead screw 20 to rotate. Because the threads at both ends of the lead screw 20 are opposite and the connecting blocks 6 are threadedly engaged with the lead screw 20, the rotation of the lead screw 20 will drive the two connecting blocks 6 to move relative to each other (or in opposite directions), thereby driving the first connecting shaft 9 and the first stirring rod 10 to move horizontally, thus increasing the fluidity of the sample and improving the dissolution efficiency.

[0029] Specifically, each of the inner walls of the first connecting sleeve 8 and the second connecting sleeve 15 is fitted with arc-shaped clamping plates 22 via springs 21. These arc-shaped clamping plates 22 respectively contact and engage with the corresponding first connecting shaft 9 and second connecting shaft 16. Through the elastic force of the springs 21, the two arc-shaped clamping plates 22 can clamp the top of the first connecting shaft 9 and the second connecting shaft 16, thus facilitating the operator's tightening of the first connecting shaft 9 and the second connecting shaft 16.

[0030] Specifically, a fastening bolt 23 is installed on the front of each connecting sleeve 8 and the front of each second connecting sleeve 15. One end of the fastening bolt 23 can contact and engage with the corresponding first connecting shaft 9 and second connecting shaft 16. The fastening bolt 23 can contact and engage with the corresponding first connecting shaft 9 and second connecting shaft 16, thereby limiting the movement of the first connecting shaft 9 and second connecting shaft 16.

[0031] Specifically, several evenly distributed support rods 24 are installed on the top surface of the base 1, and the top end of each support rod 24 slides in contact with the bottom surface of the placement plate 12. The support rods 24 provide lateral support for the placement plate 12, improving the stability of the placement plate 12.

[0032] Specifically, several evenly distributed arc-shaped fastening plates 25 are installed on the top surface of the placement plate 12, and all of the arc-shaped fastening plates 25 are in contact with and fitted with the dissolving tank 27. The arc-shaped fastening plates 25 have a limiting function on the dissolving tank 27, ensuring the stability of the dissolving tank 27.

[0033] Specifically, two left and right lateral limiting rods 26 are slidably installed on each of the horizontal plates 14, and the top of each limiting rod 26 is connected to the connecting plate 5. The limiting rods 26 limit the horizontal plate 14 to the left and right, thereby improving the stability of the horizontal plate 14.

[0034] This solution also includes a controller, the location of which is set by the staff according to the actual situation during operation. The controller is used to control all electrical components within this solution. The controller is one of an Intel processor, AMD processor, PLC controller, ARM processor, or microcontroller. It is used in conjunction with a motherboard, memory modules, storage media, and power supply, which is AC power or a 20-cell lithium battery. When a display screen is provided, a graphics card is also included.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
