Description

Technical Field

[0001] This invention relates to aquatic product sampling technology, specifically to a high-efficiency aquatic product sampling device. Background Technology

[0002] In the field of food testing, the preparation of minced meat samples from aquatic products (such as fish, shellfish, and crustaceans) typically relies on traditional homogenizing equipment, such as meat grinders and homogenizers. When preparing different batches of samples, these devices require manual disassembly and cleaning of components like blades and homogenizing cups, a cumbersome and time-consuming process that results in low sample preparation efficiency. More importantly, manual cleaning is prone to errors that can lead to residue contamination of subsequent samples, directly affecting the accuracy of test results. Although some automated equipment attempts to improve the process by incorporating cleaning modules, most employ a single-station design, preventing parallel cleaning and sample preparation. Furthermore, the complex piping systems pose a risk of secondary contamination, making it difficult to simultaneously meet the requirements of efficiency and safety. Summary of the Invention

[0003] The purpose of this invention is to provide a high-efficiency aquatic product sampling equipment to solve the problems of low efficiency caused by cumbersome manual cleaning in existing aquatic product sampling equipment, and the low efficiency caused by the single-station design which makes cleaning and sampling impossible to be carried out in parallel.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency aquatic product sample preparation device, comprising:

[0005] Base;

[0006] The circular conveyor track is fixedly installed on the base and has four stopping positions: sample injection position, homogenization position, dispensing position and cleaning position;

[0007] Two homogenizing cups are symmetrically arranged on a circular conveyor track. The homogenizing cups include:

[0008] The cup body has a drainage component at the bottom;

[0009] The top cover is detachable from the cup body;

[0010] Two sets of rotating blades are coaxially arranged inside two homogenizing cups. A first rotating drive mechanism is connected to one side of the rotating blades to drive the rotating blades to rotate around the axis of the homogenizing cup outside them.

[0011] The liftable rotating arm assembly includes a rotating arm, a lifting mechanism, and a second rotating drive mechanism. The rotating arm includes a vertical section and a horizontal section. The two ends of the horizontal section of the rotating arm are fixedly connected to the top cover. The lifting mechanism is used to drive the rotating arm to move up and down along the height direction of the homogenizing cup. The second rotating drive mechanism is used to drive the rotating arm to rotate around the center line of the annular conveying track and drive the homogenizing cup to rotate synchronously.

[0012] Furthermore, when one homogenizing cup rotates to the sample injection position, the other homogenizing cup rotates simultaneously to the dispensing position; when one homogenizing cup rotates to the homogenizing position, the other homogenizing cup rotates simultaneously to the washing position.

[0013] Two sets of rinsing nozzles correspond one-to-one with two homogenizing cups. The spraying ends of the two sets of rinsing nozzles pass through the top cover of their respective homogenizing cups and extend into the cup body. The other ends of the two sets of rinsing nozzles are connected to a water supply component for water supply.

[0014] Furthermore, the drainage assembly includes a drainage hole at the bottom of the cup body, the drainage hole being connected to a drainage pipe, and a valve A being fixedly installed on the drainage pipe.

[0015] Furthermore, the first rotary drive mechanism includes a first rotary drive component and a rotating shaft. The rotating blade is fixedly installed at the bottom end of the rotating shaft, and the top end of the rotating shaft passes through the top cover on one side and is fixedly connected to the output shaft end of the first rotary drive component. The first rotary drive component is fixedly installed on the top cover on one side.

[0016] Furthermore, the lifting mechanism includes a movable frame, both ends of which are connected to guide members that restrict the movement of the movable frame along the height direction of the homogenizing cup. A moving drive member for driving its movement is connected to one side of the movable frame, and the bottom end of the vertical section of the rotating arm is rotatably connected to the movable frame.

[0017] Furthermore, the guide includes a guide rod, and a sliding sleeve is slidably connected to the outside of the guide rod. The outer wall of the sliding sleeve is fixedly connected to the movable frame.

[0018] Furthermore, the second rotary drive mechanism includes a second rotary drive component, which is fixedly mounted on the movable frame. The output shaft end of the second rotary drive component is connected to the vertical section of the rotary arm via a transmission belt.

[0019] Furthermore, a slider is provided at the bottom of the cup body, and the slider is slidably mounted on a circular conveyor track.

[0020] Furthermore, the water supply components include a tap water inlet pipe, a purified water inlet pipe, and a water distribution assembly. The water distribution assembly includes an upper water distribution component and a lower water distribution component arranged coaxially. The inner wall of the upper water distribution component is rotatably connected to the outer wall of the lower water distribution component. The end of the rinsing spray pipe away from the homogenizing cup passes through the upper water distribution component and is connected to the inside of the water distribution assembly. One end of the tap water inlet pipe and the purified water inlet pipe passes through the lower water distribution component and is connected to the inside of the water distribution assembly. A B valve is fixedly installed on the tap water inlet pipe, the purified water inlet pipe, and the two rinsing spray pipes. The other end of the tap water inlet pipe and the purified water inlet pipe are respectively connected to an external water supply mechanism.

[0021] Compared with the prior art, the present invention provides a high-efficiency aquatic product sampling device, which uses a set ring track to carry double homogenizing cups, so that the sample feeding and dispensing station and the homogenizing and washing station operate synchronously. When one homogenizing cup is in the homogenizing position for sample processing, the other homogenizing cup is simultaneously in the washing position to complete rinsing, which effectively shortens the single batch sampling cycle and greatly improves the sampling efficiency.

[0022] The integrated flushing nozzle on the top cover, combined with the water distribution component, enables a three-stage cleaning process: two rinses with tap water and one final rinse with purified water. The entire process requires no manual intervention, effectively eliminating the risk of cross-contamination and reducing microbial residue. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Please see Figures 1 to 7 A high-efficiency aquatic product sample preparation device, including a base 1;

[0035] The circular conveyor track 2 is fixedly installed on the base 1 and has four stopping positions: sample feeding position, homogenization position, dispensing position and cleaning position;

[0036] Two homogenizing cups 3 are symmetrically arranged on the annular conveyor track 2. The homogenizing cups 3 include:

[0037] The cup body 31 has a drainage component 32 at the bottom and a slider 34 at the bottom of the cup body 31. The cup body 31 is fixed to the slider 34 by a bracket and the slider 34 is slidably mounted on the annular conveyor track 2.

[0038] The top cover 33 is detachably fitted to the cup body 31;

[0039] Two sets of rotating blades 4 are coaxially arranged inside two homogenizing cups 3. A first rotating drive mechanism 41 is connected to one side of the rotating blades 4 to drive the rotating blades 4 to rotate around the axis of the homogenizing cup 3 outside them.

[0040] The liftable rotating arm assembly 5 includes a rotating arm 51, a lifting mechanism 52, and a second rotating drive mechanism 53. The rotating arm 51 includes a vertical section and a horizontal section. The two ends of the horizontal section of the rotating arm 51 are fixedly connected to the top cover 33. The lifting mechanism 52 is used to drive the rotating arm 51 to move up and down along the height direction of the homogenizing cup 3. The second rotating drive mechanism 53 is used to drive the rotating arm 51 to rotate around the center line of the annular conveying track 2 and drive the homogenizing cup 3 to rotate synchronously.

[0041] Furthermore, when one homogenizing cup 3 rotates to the sample injection position, the other homogenizing cup 3 simultaneously rotates to the dispensing position; when one homogenizing cup 3 rotates to the homogenization position, the other homogenizing cup 3 simultaneously rotates to the cleaning position.

[0042] Two sets of rinsing nozzles 6 correspond one-to-one with two homogenizing cups 3. The spraying ends of the two sets of rinsing nozzles 6 pass through the top cover 33 of their respective homogenizing cups 3 and extend into the cup body 31. The other ends of the two sets of rinsing nozzles 6 are connected to a water supply component for water supply.

[0043] Currently, aquatic product minced meat samples are usually prepared using homogenization equipment, such as household meat grinders, homogenizers, blade grinders, and handheld homogenizers. To ensure that the samples are not contaminated, the blades, homogenizing cups, and other tools that come into direct contact with the samples need to be cleaned before each sample is prepared. However, the cleaning process requires manual disassembly of the blades and homogenizing cups, manual cleaning, and then reinstallation of the blades and homogenizing cups on the equipment. This cleaning process takes a lot of time and is inefficient. Moreover, due to human error, the tools may not be cleaned properly, causing cross-contamination of the samples and affecting the test results.

[0044] Therefore, this application rigidly connects the top cover 33 of the homogenizing cup 3 to the rotating arm 51. When the top cover 33 is on the cup body 31, the second rotary drive mechanism 53 drives the rotating arm 51 to rotate around the center line of the annular conveyor track 2. The rotating arm 51 drives the cup body 31 to rotate synchronously through the top cover 33, thus realizing the rotation of the homogenizing cup 3 around the center line of the annular conveyor track 2. This allows the homogenizing cup 3 to switch between four positions: sample injection position, homogenizing position, dispensing position, and cleaning position. Simultaneously, two homogenizing cups 3 are provided. In the initial state, one homogenizing cup 3 is located in the sample injection position (feeding position). When the material is being processed, another homogenizing cup 3 must be located at the dispensing position (sampling) (station phase difference 180°). After the rotating arm 51 rotates 90°: when one homogenizing cup 3 moves to the homogenizing position (blade homogenization), the other homogenizing cup 3 moves to the cleaning position (spray nozzle rinsing). Blade homogenization is achieved by driving the rotating blade 4 to rotate around the axis of the homogenizing cup 3 outside it through the first rotating drive mechanism 41. Spray nozzle rinsing supplies water to the rinsing nozzle 6 through the water supply component. The rinsing nozzle 6 inputs cleaning water (tap water and purified water) into the homogenizing cup 3 to rinse the rotating blade 4 and the inner wall of the homogenizing cup 3.

[0045] Meanwhile, when the homogenizing cup 3 is in the sample inlet / dispensing position, the lifting mechanism 52 drives the rotating arm 51 to move upward, causing the top cover 33 to move upward to expose the cup opening, so as to put the sample into the cup body 31 and take the sample; when in the homogenizing position / washing position, the lifting mechanism 52 drives the rotating arm 51 to move upward, causing the top cover 33 to move downward to seal the cup opening of the cup body 31.

[0046] A closed-loop cleaning process was achieved, replacing manual disassembly and effectively improving sample preparation efficiency. Furthermore, the asynchronous operation of the dual homogenizing cups 3 allows homogenization and cleaning to proceed in parallel, further enhancing sample preparation efficiency.

[0047] In one embodiment of the present invention, the drainage assembly 32 includes a drainage hole opened at the bottom of the cup body 31, the drainage hole is connected to a drainage pipe 321, and a valve A 322 is fixedly installed on the drainage pipe 321.

[0048] Specifically, during the cleaning process, valve A 322 is opened, and the waste liquid is discharged through drain pipe 321. Valve A 322 can be an electromagnetic diaphragm valve.

[0049] In one embodiment of the present invention, the first rotary drive mechanism 41 includes a first rotary drive member 411 and a rotating shaft 412. The rotating blade 4 is fixedly installed at the bottom end of the rotating shaft 412. The top end of the rotating shaft 412 passes through the top cover 33 on one side and is fixedly connected to the output shaft end of the first rotary drive member 411. The outer side wall of the rotating shaft 412 is rotatably connected to the top cover 33. The first rotary drive member 411 is fixedly installed on the top cover 33 on one side. The first rotary drive member 411 can be a motor or a rotary cylinder.

[0050] Specifically, when the homogenizing cup 3 enters the homogenizing station, the first rotary drive 411 is activated, and the output torque is transmitted to the rotating blade 4 via the rotating shaft 412, driving the blade to rotate at high speed to cut the sample; the rotating shaft 412 and the top cover 33 can achieve dynamic sealing through bearings to ensure zero leakage of slurry during the homogenizing process.

[0051] In one embodiment of the present invention, the outer side wall of the rotating arm 51 is movably connected to the base 1, the lifting mechanism 52 includes a movable frame 521, both ends of the movable frame 521 are connected to guide members that restrict the movement of the movable frame 521 along the height direction of the homogenizing cup 3, one side of the movable frame 521 is connected to a movable drive member 522 for driving its movement, the movable drive member 522 is a telescopic cylinder or a hydraulic cylinder, the movable end of the movable drive member 522 is fixedly connected to the movable frame 521, the fixed end of the movable drive member 522 is fixedly connected to the base 1, and the bottom end of the vertical section of the rotating arm 51 is rotatably connected to the movable frame 521.

[0052] The guide includes a guide rod 523, with both ends of the guide rod 523 fixedly connected to the base 1. A sliding sleeve 524 is slidably connected to the outside of the guide rod 523, and the outer side wall of the sliding sleeve 524 is fixedly connected to the movable frame 521.

[0053] Specifically, when the equipment needs to switch workstations, the moving drive component 522 drives the moving frame 521 to rise and fall vertically along the guide rod 523, thereby raising or lowering the rotating arm 51 as a whole; the sliding sleeve 524 is precisely engaged with the guide rod 523 to constrain the moving direction of the moving frame 521; after the lifting and lowering are in place, the second rotating drive mechanism 53 drives the arm to rotate horizontally.

[0054] In one embodiment of the present invention, the second rotary drive mechanism 53 includes a second rotary drive member, which is fixedly mounted on the movable frame 521. The output shaft end of the second rotary drive member is connected to the vertical section of the rotary arm 51 via a transmission belt.

[0055] Specifically, when a workstation needs to be switched, the second rotary drive unit is activated, transmitting torque to the vertical section of the rotating arm 51 via a transmission belt, driving the double homogenizing cups 3 to be precisely positioned to the target workstation. The second rotary drive unit can be used in conjunction with a servo motor and a harmonic reducer. The output shaft of the servo motor is connected to the input end of the harmonic reducer. Both the output end of the harmonic reducer and the vertical section of the rotating arm 51 are fixedly fitted with transmission wheels. The two transmission wheels are fitted with the same transmission belt. The harmonic reducer converts the high-speed output of the motor into high-precision indexing motion, improving the accuracy of the equipment operation.

[0056] In one embodiment of the present invention, the water supply component includes a tap water inlet pipe 61, a purified water inlet pipe 62, and a water distribution assembly 63. The water distribution assembly 63 includes an upper water distribution component 631 and a lower water distribution component 632 arranged coaxially. The upper water distribution component 631 is fixedly installed on the outside of the rotating arm 51. The inner side wall of the upper water distribution component 631 is rotatably connected to the outer side wall of the lower water distribution component 632. One end of the flushing spray pipe 6 away from the homogenizing cup 3 passes through the upper water distribution component 631 and is connected to the inside of the water distribution assembly 63. One end of the tap water inlet pipe 61 and the purified water inlet pipe 62 passes through the lower water distribution component 632 and is connected to the inside of the water distribution assembly 63. A B valve 64 is fixedly installed on the tap water inlet pipe 61, the purified water inlet pipe 62, and the two flushing spray pipes 6. The B valve 64 can be an electromagnetic diaphragm valve. The other end of the tap water inlet pipe 61 and the purified water inlet pipe 62 are respectively connected to an external water supply mechanism.

[0057] Specifically, when the rotating arm 51 drives the homogenizing cup 3 to rotate, the flushing nozzle 6 fixed to the top cover 33 rotates accordingly. The upper water distribution component 631 is fixed to the rotating arm 51 and rotates synchronously. Both the tap water inlet pipe 61 and the purified water inlet pipe 62 are rigid pipes to support the lower water distribution component 632. The lower water distribution component 632 can also be fixed by a bracket. A sealing ring is provided between the upper water distribution component 631 and the lower water distribution component 632. The tap water and purified water inlet pipes 62 are transported to the flushing nozzle 6 through the axial channels inside the upper water distribution component 631 and the lower water distribution component 632. The switching between tap water and purified water is realized by controlling the closing of valve B 64.

[0058] In one embodiment of the present invention, a corresponding control unit can be set up for cooperative use. This control unit can be any type of controller connected to the electrical components in this application, thereby controlling the start-up and shutdown of each electrical component. This part is prior art. Here, a microcontroller can be provided as the control unit for demonstration. In this embodiment, the microcontroller is a typical embedded microcontroller unit, consisting of an arithmetic logic unit (ALU), a controller, memory, input / output devices, etc., equivalent to a miniature computer. Compared with general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings.

[0064] Steps 4-6: Three-stage automatic cleaning:

[0068] Step 7, Return to the initial position: The control unit starts the second rotary drive mechanism 53 to control the rotating arm 51 to rotate 90°, and the double homogenizing cups 3 rotate synchronously to the injection position and the dispensing position, and the rotating arm 51 is raised to open the top cover 33;
