Description

Technical Field

[0001] The present invention relates to the technical field of food preservative detection, and more particularly to a food preservative detection sampling device. Background Art

[0002] Through regular testing and sampling, potential safety hazards can be discovered and eliminated in a timely manner, preventing food poisoning accidents.

[0003] During testing, the food needs to be sampled and crushed, then stirred and the reagents are dropped into the mixture after stirring, and then purified and separated before testing.

[0004] Chinese patent document (CN116990102A) discloses a pre-prepared food preservative detection device, which states in the specification that "a pre-prepared food preservative detection device comprises a base, a servo motor is fixedly mounted in the middle of the top of the base, and a clean water tank, a crushing tank, a mixing detection tank and a cleaning tank are respectively mounted at equal angles on the top of the base, and the angles between the clean water tank, the crushing tank, the mixing detection tank and the cleaning tank are all ninety degrees. The present invention cooperates with the absorption and injection of the solution, and utilizes the injection process of the solution or clean water to achieve the expansion of the stirring and crushing range, so that stirring and crushing are carried out immediately after injection, and at the same time utilizes the absorption process of the solution to achieve the reduction of the stirring range, so that the stirring range is reduced to the minimum value, and the degree of disturbance of the solution is reduced to the minimum, which can minimize the problem of more internal residues in the extracted solution due to the stirring and crushing structure, improve the mixing uniformity of the extracted solution, and will not affect the crushing, thereby improving the detection quality". However, in actual use, it can only combine the stirring and crushing steps, and still requires a large amount of equipment and the cooperation of multiple personnel to use, and has a large demand for human resources.

[0005] At present, many food preservative testing equipment still tends to handle key steps such as stirring and crushing, solvent mixing, purification and separation independently in design. This decentralized processing method brings multiple challenges in practical applications. First, it often requires the collaborative work of multiple staff members, which undoubtedly increases the consumption of human resources. The connection and coordination of each step need to be carefully arranged to ensure the smooth progress of the testing process. Secondly, this processing method also means that a variety of different equipment are needed to complete the entire testing process. This not only puts high demands on the equipment configuration of the laboratory, but also challenges the skill level of the operators. They need to master the operating skills of various equipment to ensure the accuracy and reliability of the test results. However, in actual operation, this reliance on multiple equipment and multiple skills often increases the difficulty of testing and sampling, making it difficult to ensure the efficiency of testing. In view of this, we propose a food preservative detection sampling device. Summary of the invention

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention designs a driving component, a transmission component and a movable component. After the raw material is injected into the feed port, the low-speed operation mode is started, and the driving gear is driven by the low-speed operation of the driving component. At this time, the driving gear drives the four driven components to rotate, and at the same time, the transmission component and the movable component rotate at the same time, and the transmission component drives the grinding component to rotate in the opposite direction to the movable component, so that the raw material is crushed through the contact part between the grinding component and the movable component. While the movable component rotates, because it is connected to the guide component, the movable component moves up and down repeatedly along the surface of the guide component, thereby mixing the reagent and the raw material. When running at high speed, the drive shaft assembly is deformed and synchronously drives the docking assembly to rotate. At this time, the four processing cylinders will revolve along the motor due to the drive of the driven assembly, and the centrifugal treatment of the raw materials is realized under the high-speed rotation state. Compared with the existing equipment, the device only needs personnel to control the high-speed and low-speed operation of the motor to realize the steps of stirring and crushing, solvent mixing and purification and separation of the raw materials, which reduces the steps and equipment required for sampling and testing food, and at the same time reduces the demand for personnel for machine operation, and avoids the situation where the investment of a large amount of equipment and human resources leads to rising costs, thereby reducing the difficulty of sampling and testing, and ensuring the detection efficiency.

[0031] 2. The present invention also designs a grinding component, a transmission component, a movable component and a guide component. After the raw material is injected into the feed port, a low-speed operation mode is started. At this time, the driving gear will drive the four driven gears to rotate, and the driven gear will synchronously drive the first transmission wheel and the grinding roller to rotate through the rotator. At the same time, because the grinding roller will discharge several guide blocks and several sealing sheets below under the action of centrifugal force when rotating, so that the sealing sheet fits with the collecting barrel below, thereby ensuring that the grinding roller can drive the raw material in the collecting barrel to circulate quickly in the two collecting barrels through several sealing sheets when moving up and down, so that a large amount of raw material flows through the grinding barrel multiple times. On the one hand, by driving the raw material to flow, it is made to contact with the grinding barrel and the grinding roller multiple times, thereby ensuring the grinding and crushing effect of the raw material. On the other hand, after the raw material reagent is put in, the device can improve the mixing effect between the raw material and the reagent by accelerating the flow of the raw material in the collecting barrel, and at the same time, reduce the difficulty of using the device.

[0032] 3. The present invention also designs a driven component and a docking component. When the motor is at high speed, the motor will drive the driving shaft to rotate at high speed. At this time, several counterweights outside the driving shaft will pull the elastic telescopic rod to extend under the action of centrifugal force. At this time, the driving teeth will be engaged between the docking teeth, so that the driving shaft is synchronously driven by the docking wheel and the connecting plate, so that the four processing cylinders rotate as a whole, and the centrifugal force generated during the overall rotation is used to centrifuge the sample, so that the device can not only quickly complete the sampling and processing of food, but also the equipment is convenient to use, the equipment cost is low, and it is more convenient to promote and use.

[0061] Working principle: This embodiment provides a food preservative detection sampling device. When in use, the high-speed operation mode and the low-speed operation mode of the motor 102 can be adjusted to achieve the crushing of food raw materials, the mixing of reagents and centrifugal separation. After the raw materials are processed, the discharge port 209 can be opened and the samples can be tested;

[0062] After the raw material is injected into the feed port 208, the low-speed operation mode is started, and the driving gear 104 is driven by the low-speed operation of the driving component 103. At this time, the driving gear 104 will drive the four driven components 202 to rotate. At the same time, the transmission component 204 and the movable component 205 will rotate at the same time, and the transmission component 204 will drive the grinding component 203 to rotate in the opposite direction of the movable component 205, so that the raw material is crushed through the contact part between the grinding component 203 and the movable component 205. While the movable component 205 rotates, since it is connected to the guide component 207, the movable component 205 will repeatedly move up and down along the surface of the guide component 207, so as to mix the reagent and the raw material. When running at a high speed, the driving shaft 1031 component is deformed and synchronously drives the docking component 105 to rotate. At this time, the four processing cylinders 201 will be driven by the driven component 202 to revolve along the motor 102, and the raw material is centrifuged under the high-speed rotation state.

[0063] After the raw material is injected into the feed port 208, the low-speed operation mode is started. By running the driving shaft 1031 at a low speed, the counterweight block 1033 and the driving latch 1034 remain in place due to insufficient centrifugal force. At this time, the driving gear 104 will drive the four driven gears 2024 to rotate, and the driven gear 2024 will synchronously drive the first transmission wheel 2025 and the grinding roller 2051 to rotate through the rotator 2023. When the first transmission wheel 2025 drives the second transmission wheel 2043 to rotate, it will synchronously drive the transmission gear block 2035 in the collecting barrel 2031, so that the collecting barrel 2031 and the grinding roller 2051 rotate in the opposite direction, so that the raw material will be affected when it flows in the collecting barrel 2031. Grinding, and as the grinding roller 2051 rotates, the grinding roller 2051 will reciprocate up and down on the surface of the guide rod 2072 due to the setting of the connecting hole 2052, the connecting block 2053 and the second guide groove 2074. At the same time, because the grinding roller 2051 will discharge the several guide blocks 2056 and the several sealing sheets 2055 below under the action of centrifugal force when rotating, so that the sealing sheet 2055 fits with the collecting barrel 2031 below, thereby ensuring that the grinding roller 2051 can drive the raw materials in the collecting barrel 2031 to quickly flow in the two collecting barrels 2031 through the several sealing sheets 2055 when moving up and down, so that a large amount of raw materials flow through the grinding barrel 2032 multiple times;

[0064] After the raw materials are crushed and mixed, it is necessary to stop the operation of the equipment briefly. At this time, several sealing sheets 2055 will lose the centrifugal force during rotation and reset under the action of the elastic force of the spring 2057. The raw materials will fall into the processing cylinder 201 under the action of gravity due to the loss of the shielding of the sealing sheets 2055. Then the operation mode of the motor 102 is changed. When the high-speed motor 102 is turned on, the motor 102 will drive the drive shaft 1031 to rotate at a high speed. At this time, several counterweights 1033 outside the drive shaft 1031 will pull the elastic telescopic rod 1032 to extend under the action of centrifugal force. At this time, the driving tooth 1034 will be engaged between the docking teeth 1052, so that the drive shaft 1031 is synchronously driven by the docking wheel 1051 and the connecting plate 2022, so that the four processing cylinders 201 rotate as a whole, and the sample is centrifuged through the centrifugation generated during the overall rotation.
