Description

Technical Field

[0001] This utility model relates to the field of sampling equipment, specifically a vitamin E synthesis sampling device. Background Technology

[0002] Vitamin E (VE) is a general term for tocopherols, a golden or pale yellow oily substance with a mild, characteristic odor. Vitamin E is easily oxidized by light and air, turning dark red. It is miscible with acetone, chloroform, ether, or vegetable oils, but almost insoluble in water. Vitamin E is one of the earliest discovered vitamins and is an essential fat-soluble vitamin. As an excellent antioxidant and nutrient, it is widely used in clinical, pharmaceutical, food, feed, health product, and cosmetic industries. During the production and processing of vitamin E, sampling equipment is required to sample the synthesized vitamin E solution.

[0003] According to publicly available patent 202220433822.9, a vitamin E synthesis sampling device, the device includes a gun body. A handle is located on one side of the bottom of the gun body, with a handguard on the inner side of the handle. An operation button is located on the inner side of the upper end of the handle. An observation window is located on one side of the middle of the gun body. A protective cover is located at the front end of the gun body. Several sets of bolts are located on the exterior of the gun body. A base is located at the rear end of the gun body, and an electric push rod is connected to the base. A piston is connected to the top of the electric push rod. A piston cylinder is slidably connected to the piston. One end of the piston cylinder is connected to one end of a liquid storage tank. The other end of the liquid storage tank is connected to one end of a flexible tube. The other end of the flexible tube is connected to one end of a threaded tube, and a suction nozzle is located at the other end of the threaded tube. By incorporating a battery and an operation button, the operator can perform sampling operations without connecting to a power source. Furthermore, the sampling and nozzle extension / retraction can be directly controlled via the operation button, improving practicality.

[0004] However, in practice, traditional vitamin E synthesis sampling devices use a single nozzle to extract vitamin E synthesis solution samples. After sampling one type of vitamin E synthesis solution and drawing it into the storage tank, if it is necessary to sample another type of vitamin E synthesis solution, the existing synthesis solution in the storage tank must be emptied first to avoid mixing of different types of vitamin E synthesis solutions in the tank, which would affect the purity and accuracy of the sampling and make it difficult for the device to sample different types of vitamin E separately. Therefore, a new technical solution needs to be designed to address this issue. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a vitamin E synthesis sampling device. This addresses the problem that current traditional vitamin E synthesis sampling devices use a single nozzle to extract vitamin E synthesis solution samples. After sampling one type of vitamin E synthesis solution and drawing it into the storage tank, if it is necessary to sample another type of vitamin E synthesis solution, the existing synthesis solution in the storage tank must be emptied first to avoid mixing of different types of vitamin E synthesis solutions in the tank, which affects the purity and accuracy of the sampling and makes it difficult for the device to sample different types of vitamin E separately.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a vitamin E synthesis sampling device is designed, including a device housing, a placement groove is opened at the front end of the device housing, a cover plate is installed inside the placement groove, a handle is fixed on one side of the device housing, a drive motor is embedded on the other side of the device housing, a rotating rod is connected to one end of the drive motor, a fixed housing is fixed at the end of the rotating rod away from the drive motor, and a bidirectional sampling component is provided inside the fixed housing.

[0007] Preferably, the bidirectional sampling assembly includes a dual-axis motor, a threaded rod, a moving plate, a moving tube, a sampling head, a piston ring, a tube head, a hose, a micro liquid pump, and a storage tank.

[0008] Preferably, the dual-axis motor is installed on one side of the inner wall of the fixed housing, and both ends of the dual-axis motor are connected to threaded rods. The outer walls of the two threaded rods are provided with the same threads. A movable plate passes through the outside of the threaded rods, and the threaded holes inside the movable plate are threadedly connected to the threaded rods.

[0009] Preferably, a movable tube is fixed to one end of the movable plate, and the end of the movable tube away from the movable plate extends into the sampling head. The end of the movable tube inside the sampling head passes through a piston ring and is connected to a tube head, and the penetration position of the piston ring and the movable tube is fixed.

[0010] Preferably, the other end of the movable tube is connected to a flexible tube, and the end of the flexible tube away from the movable tube passes through the movable plate and is connected to a micro liquid pump, which is connected to one end of the storage tank.

[0011] Preferably, the storage box is installed in a mounting hole on the surface of the fixed housing, and the storage box extends into the fixed housing. One end of the liquid pipe is connected to the outer surface of the fixed housing, and the other end of the liquid pipe is detachably connected to a pipe cap.

[0012] Preferably, the plurality of sampling heads are respectively inserted through both ends of the fixed housing, and the insertion positions of the sampling heads and the fixed housing are fixed.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model combines a drive motor, a fixed housing, and a bidirectional sampling assembly. The drive motor rotates the sampling heads at both ends of the fixed housing, enabling the sampling heads to switch positions and move to the bottom to sample vitamin E synthetic solution at different locations. Furthermore, the device is equipped with dual storage tanks and a micro-liquid pump. When the piston moves and draws vitamin E synthetic solution into the sampling head, the micro-liquid pump quickly draws the solution from the sampling head into the storage tank. The piston movement controls the sampling volume, ensuring accuracy for each sample. Additionally, vitamin E synthetic solution tends to have high viscosity, which increases the difficulty of extraction. The initial movement of the piston... Initial suction breaks the surface tension of the liquid, providing sufficient initial flow to the micro-liquid pump and thus enhancing its suction capacity. Through the cooperation of the piston and the micro-liquid pump, the sampling efficiency is effectively improved. This solves the technical problem of traditional vitamin E synthesis sampling devices that use a single nozzle to extract vitamin E synthesis liquid samples. After sampling one type of vitamin E synthesis liquid and sucking it into the storage tank, if it is necessary to sample another type of vitamin E synthesis liquid, the existing synthesis liquid in the storage tank must be emptied first to avoid mixing of different types of vitamin E synthesis liquid in the tank, affecting the purity and accuracy of the sampling, and making it difficult for the device to sample different types of vitamin E separately.

[0015] 2. This utility model combines a dual-axis motor, a threaded rod, and a moving plate. The dual-axis motor drives the threaded rod, which simultaneously moves multiple moving tubes in the same direction. When one sampling head reaches the bottom position, the dual-axis motor drives the corresponding moving tube upwards, which in turn moves the piston ring at the bottom upwards, enabling the sampling head to sample the vitamin E synthesis solution. Simultaneously, the moving tube above, driven by the dual-axis motor, also moves its internal piston ring upwards, completing a reset action and preparing for the next sampling. This achieves automatic reset of the other sampling head during the sampling process, effectively improving sampling efficiency. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: A vitamin E synthesis sampling device, see [link to example]. Figures 1 to 3The device includes a housing 1, with a placement groove 101 at its front end. A cover plate 102 is installed inside the placement groove 101. A handle is fixed to one side of the housing 1, and a drive motor 2 is embedded in the other side of the housing 1. One end of the drive motor 2 is connected to a rotating rod 201, and a fixed housing 202 is fixed to the end of the rotating rod 201 away from the drive motor 2. A bidirectional sampling component is installed inside the fixed housing 202. First, the drive motor 2 drives the rotating rod 201 to rotate, and the rotation of the rotating rod 201 in turn drives the fixed housing 202 to rotate. The rotation causes one of the sampling heads 211 on the fixed housing 202 to rotate to the bottom position. Once the sampling head 211 reaches the bottom and is fully immersed in the synthesis liquid, the dual-axis motor 207 starts. The dual-axis motor 207 drives the threaded rod 208 located at the bottom to rotate via its output shaft. As the threaded rod 208 rotates, the threadedly connected moving tube 210 moves upward along the direction of the threaded rod 208. This movement, in turn, causes the piston ring 214 located inside the moving tube 210 to move upward, thereby creating a negative pressure inside the sampling head 211. Due to the negative pressure... Under pressure, the vitamin E synthesis solution is smoothly drawn into the sampling head 211. Then, the micro-liquid pump 213 starts, using its suction capacity to draw the vitamin E synthesis solution from the sampling head 211 through the tube head 215 and the moving tube 210, and then transport it through the connected hose 212 to the storage tank 204 for storage. When another vitamin E synthesis solution needs to be extracted, simply use the drive motor 2 to rotate the fixed housing 202 again, causing the other sampling head 211 to rotate to the bottom position, and repeat the above extraction steps, thus achieving multiple extractions. The rapid switching and efficient sampling between sample heads 211 greatly improve the efficiency and accuracy of sampling work. It solves the technical problem of traditional vitamin E synthesis sampling devices that use a single nozzle to extract vitamin E synthesis solution samples. After completing the sampling of one type of vitamin E synthesis solution and sucking it into the storage tank, if it is necessary to sample another type of vitamin E synthesis solution, the existing synthesis solution in the storage tank must be emptied first to avoid mixing of different types of vitamin E synthesis solutions in the tank, which would affect the purity and accuracy of the sampling and make it difficult for the device to sample different types of vitamin E separately.

[0022] For details, see Figure 2 The bidirectional sampling assembly includes a dual-axis motor 207, a threaded rod 208, a moving plate 209, a moving tube 210, a sampling head 211, a piston ring 214, a tube head 215, a hose 212, a micro liquid pump 213, and a storage tank 204.

[0023] Further, see Figure 2The dual-axis motor 207 is installed on one side of the inner wall of the fixed housing 202. Both ends of the dual-axis motor 207 are connected to threaded rods 208. The outer walls of the two threaded rods 208 are provided with the same threads. A movable plate 209 passes through the outside of the threaded rods 208. The screw holes in the movable plate 209 are threadedly connected to the threaded rods 208.

[0024] It is worth noting that, see Figure 2 and Figure 3 A movable tube 210 is fixed to one end of a movable plate 209. The end of the movable tube 210 away from the movable plate 209 extends into a sampling head 211. The end of the movable tube 210 inside the sampling head 211 passes through a piston ring 214 and is connected to a tube head 215. The piston ring 214 and the movable tube 210 are fixed at the same penetration position. During sampling, when one of the sampling heads 211 reaches the bottom position as the movable tube 210 moves, the dual-axis motor 207 drives the piston ring 214 at the bottom of the movable tube 210 to move upward via a threaded rod 208. The upward movement of the piston ring 214... A negative pressure area is formed inside the sampling head 211, which allows the vitamin E synthesis liquid to be smoothly drawn into the sampling head 211 under the action of external atmospheric pressure, completing the sampling operation. Driven by the dual-axis motor 207, the upper moving tube 210 also moves synchronously. During the upward movement of the upper moving tube 210, the piston ring 214 completes the reset action, that is, returns to the initial position, ready for the next sampling. This realizes the automatic reset of the other sampling head 211 during the sampling process without the need for an additional reset mechanism or step, which greatly improves the efficiency and continuity of sampling.

[0025] It is worth noting that, see Figure 2 The other end of the movable tube 210 is connected to a flexible tube 212. The end of the flexible tube 212 away from the movable tube 210 passes through the movable plate 209 and is connected to a micro liquid pump 213. The micro liquid pump 213 is connected to one end of the storage box 204.

[0026] It is worth mentioning that, see Figure 1 and Figure 2 The storage box 204 is installed in the mounting hole 203 on the surface of the fixed housing 202, and the storage box 204 extends into the fixed housing 202. One end of the liquid pipe 205 is connected to the outer surface of the fixed housing 202, and the other end of the liquid pipe 205 is detachably connected to the pipe cap 206.

[0027] It is worth emphasizing that, see Figure 2 Multiple sampling heads 211 are respectively inserted through both ends of the fixed housing 202, and the insertion positions of the sampling heads 211 and the fixed housing 202 are fixed.

[0028] It should be noted that the drive motor 2 controls its rotation direction to move multiple sampling heads 211 to the bottom position in a clockwise and counterclockwise manner. Instead of making the sampling heads 211 rotate continuously, the clockwise and counterclockwise rotation method is adopted, which effectively avoids the problem of wires (such as power lines, signal lines, etc.) tangling, ensures the smooth progress of the sampling process, and improves the reliability and stability of the device.

[0029] When using a vitamin E synthesis sampling device, the drive motor 2 first drives the rotating rod 201 to rotate. The rotation of the rotating rod 201 then drives the fixed housing 202 to rotate, causing one of the sampling heads 211 on the fixed housing 202 to rotate to the bottom position. When the sampling head 211 reaches the bottom and is completely immersed in the synthesis liquid, the dual-axis motor 207 is then started. The dual-axis motor 207 drives the threaded rod 208 located at the bottom to rotate through its output shaft. As the threaded rod 208 rotates, the movable tube 210 threaded to it moves along the threaded rod 208. The direction of 08 moves upward, which in turn moves the piston ring 214 located in the moving tube 210 upward, thereby creating a negative pressure inside the sampling head 211. Due to the negative pressure, the vitamin E synthesis solution is smoothly drawn into the sampling head 211. Then, the micro liquid pump 213 starts. Using its suction capacity, the micro liquid pump 213 draws the vitamin E synthesis solution in the sampling head 211 through the tube head 215 and the moving tube 210, and then delivers it to the storage tank 204 for storage through the connected hose 212. When it is necessary to extract another type of vitamin E synthesis solution, only... The drive motor 2 is used again to rotate the fixed housing 202, causing another sampling head 211 to rotate to the bottom position, and the above extraction steps are repeated. This achieves rapid switching and efficient sampling between multiple sampling heads 211, greatly improving the efficiency and accuracy of the sampling work. During the sampling process, when one of the sampling heads 211 reaches the bottom position as the moving tube 210 moves, the dual-axis motor 207 drives the piston ring 214 located at the bottom of the moving tube 210 to move upward via the threaded rod 208. The upward movement of the piston ring 214 forms a [feature] inside the sampling head 211. A negative pressure zone was created, allowing the vitamin E synthesis solution to be smoothly drawn into the sampling head 211 under the action of external atmospheric pressure, completing the sampling operation. Driven by the dual-axis motor 207, the upper moving tube 210 also moves synchronously. During the upward movement of the upper moving tube 210, the piston ring 214 completes the reset action, that is, returns to the initial position, ready for the next sampling. This realizes the automatic reset of the other sampling head 211 during the sampling process without the need for an additional reset mechanism or step, greatly improving the efficiency and continuity of sampling.
