Description

Technical Field

[0001] This invention relates to the field of moisture detection technology, and specifically to a moisture detection device for air-drying beef jerky production. Background Technology

[0002] Beef jerky is primarily made from beef, typically using tender cuts like tenderloin and shank with relatively regular marbling and a moderate fat content. This results in a better-tasting jerky. However, during processing, factors such as different batches of beef and varying processing environments can affect the final moisture content of the jerky. Therefore, testing the moisture content of dried samples allows for timely understanding of the actual drying process's effectiveness, ensuring that subsequent products meet moisture content standards. Currently, a weighing instrument is commonly used to test the moisture content of dried beef. This instrument has multiple heating rods neatly fixed to both sides of its internal cavity, and the upper surface of the plate... An electric heating plate is also fixed on the surface. Compared with traditional moisture measuring devices, this device does have certain convenience in moisture measurement. Since beef itself contains tough tissues such as fascia, relying solely on heating rods to air-dry beef jerky samples often results in the outer side of the beef drying first, while the inner fascia area still retains moisture. As a result, the moisture content varies between different areas within the same beef jerky sample, which will inevitably bring a relatively large error to the detection of the overall actual air-dried moisture content of the beef jerky sample, thus greatly reducing the accuracy of the experimental data. Summary of the Invention

[0003] The purpose of this invention is to provide a moisture detection device for air-drying beef jerky production, in order to overcome the above-mentioned shortcomings in the technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a moisture detection device for beef jerky production, comprising a weighing instrument, a heating coil, and several beef jerky samples. The top of the weighing instrument is hinged with a sealing cylinder cover that closes or opens the heating coil within the weighing instrument. Inside the sealing cylinder cover is a dehydration assembly for stably detecting the several beef jerky samples. The dehydration assembly includes several sets of positioning pins installed inside the sealing cylinder cover, and adjacent sets of positioning pins are connected to a mounting frame. Inside the sealing cylinder cover is a rotating column for driving the mounting frame. Between the rotating column and the mounting frame is a connecting plate and a swing frame for fine-tuning the beef jerky samples within the positioning pins, and the swing frame is configured with a W-shaped structure. One side of the rotating column is provided with a swing-pushing assembly that drives the connecting plate. Between the positioning pins and the rotating column is a pressure platform assembly that cooperates with the swing-pushing assembly. Between the sealing cylinder cover and the positioning pins is a receiving and pushing assembly that stably places the beef jerky samples inside the weighing instrument in the middle.

[0005] Preferably, the mounting bracket has two sliders slidably connected on the side near the rotating column, and the two sliders are used to drive the positioning pin to move relative to or towards each other along one side of the mounting bracket. The two sliders are connected together by an extension guide rod and a return spring, and the return spring is sleeved on the outside of the extension guide rod.

[0006] Preferably, the swing-push assembly includes a concentric column installed between the connecting plate and the rotating column, and a slide slidably connected to one side of the rotating column. The slide slides along one side of the connecting plate. A guide cone is installed on the top of the connecting plate. A swing groove is provided on one side of the slide for the guide cone to move and swing. The swing groove is configured with a corrugated structure. An electric push rod is installed on the side of the rotating column near the slide. The output end of the electric push rod is used to push the slide to move up and down reciprocally.

[0007] Preferably, the bottom end of the connecting plate is provided with several threaded grooves, the top of the swing frame is provided with a screw hole seat, and the screw hole seat and the connecting plate are kept in an inserted and uninserted state. An adjusting bolt is screwed on the outside of the screw hole seat, and the adjusting bolt is screwed into the threaded groove corresponding to the screw hole seat through the screw hole seat.

[0008] Preferably, the pressure table assembly includes a stabilizing sleeve fixedly connected to one side of the rotating column, and a shaft connected to one side of each of the two sliders. Two pressure table arms are movably sleeved on the outside of the two shafts, and a shaft column is sleeved between the two pressure table arms. One end of the shaft column is fixedly connected to a force push rod, and one end of the force push rod passes through the stabilizing sleeve and abuts against the bottom end of the electric push rod.

[0009] Preferably, the receiving and pushing assembly includes a guide frame fixedly connected inside the sealed cylinder cover and a receiving block slidably connected to one side of the guide frame. A rotating disk is rotatably connected inside the sealed cylinder cover, and a rocker arm is installed at one end of the rotating disk. A servo motor is fixedly connected to the outside of the sealed cylinder cover, and the servo motor is used to drive the rotating disk to rotate. A sliding push rod is movably connected to one side of the receiving block, and the sliding push rod is set with an inverted T-shaped structure. The sliding push rod is movably sleeved on one end of the rocker arm. A column is installed at the bottom of the receiving block, and a receiving guide plate is fixedly connected to the bottom of the column. The receiving guide plate is used to guide the beef jerky sample to the middle position of the weighing instrument. A counter-flow adjustment assembly that drives the column to rotate is provided on one side of the guide frame.

[0010] Preferably, the reverse flow adjustment assembly includes an attachment frame fixedly connected to the bottom end of the guide frame, a stabilizing crossbar connected between the connecting block and the column, a positioning groove for the stabilizing crossbar to move on one side of the attachment frame, a flipping groove communicating with the inside of the positioning groove on the top of the attachment frame, a semi-rocker mounted on the outside of the stabilizing crossbar, the semi-rocker being located inside the positioning groove and the flipping groove, a gear fixedly sleeved on the outside of the stabilizing crossbar, and a rack meshing with the gear fixedly connected to the bottom of the attachment frame.

[0011] Preferably, the receiving plate is configured with a shovel-shaped structure to ensure that the bottom of the beef jerky sample is tilted after contacting the receiving plate.

[0012] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0013] 1. The present invention, through the setting of positioning pin, rotating column, sealing cylinder cover and heating ring, clamps both ends of the beef jerky sample with positioning pin, and the sample is relatively fixed in position inside the sealing cylinder cover. Each part can receive heat more evenly, and the process of moisture loss from the inside of the sample to the surface is also more uniform, thus improving the reliability of beef jerky sample detection.

[0014] 2. By setting up positioning pins, sliders and return springs, this invention can form a relatively balanced and appropriate clamping force between the positioning pins and the sample according to the actual shape of the sample. This prevents the sample from being squeezed or scratched during the restriction process due to forced fixation, thus protecting the integrity of the sample and facilitating subsequent accurate detection and analysis.

[0015] 3. The present invention makes the operation of the positioning pin more convenient and flexible when clamping the beef jerky sample by the existence of the slider. It eliminates the need for complex operations such as maintaining precise alignment between the sample and the positioning pin or forcibly clamping it. The staff can quickly fix the sample and put it into the sealed cylinder cover. At the same time, the sample can be easily removed after drying, which reduces the time spent in the clamping process and improves the work efficiency of the entire drying and testing process.

[0016] 4. The present invention, through the setting of positioning pin, sealing cylinder cover and heating ring, the tooth-shaped structure of positioning pin breaks the continuity between it and the sample surface, so that hot air can better contact more parts of the beef jerky sample through the gap between the teeth during the drying process, accelerate the air flow to remove moisture, further improve the drying efficiency, and allow the sample to reach the appropriate degree of dryness more quickly.

[0017] 5. By setting up positioning pins, pressure table arms, electric push rods and force push rods, the present invention allows the moisture inside the beef jerky sample to gradually migrate to the surface and evaporate during the drying process. By slowly moving one set of positioning pins away from the beef jerky sample, this relatively fixed obstruction pattern can be broken, allowing the moisture that might have accumulated in that area to have more space and channels to diffuse to the surrounding area. This avoids excessive moisture residue in some areas, promotes more uniform moisture loss from the entire sample, and ensures the consistency of the drying effect.

[0018] 6. The present invention, through the setting of electric push rod, slide, connecting plate, swing frame and positioning pin, can make the beef jerky sample swing slightly in the positioning pin, so that the air around the beef jerky sample can flow better, the hot air can come into full contact with each surface of the sample, accelerate the removal of moisture evaporated from the sample, and enhance the air circulation around the beef jerky sample.

[0019] 7. The present invention, through the setting of sliding push rod, guide plate, swing shaft arm, beef jerky sample and weighing instrument, can automatically take out the beef jerky sample in the positioning pin, and guide the taken out beef jerky sample to the middle position of the weighing instrument under the action of the guide plate, which can ensure that the weighing pan is evenly stressed and ensure that the test is based on the original stable state of the sample, thereby further improving the reliability of the test results.

[0020] 8. By using the guide plate, half-rocker, sliding push rod, and swing shaft arm, the sliding push rod is designed to reciprocate along the inside of the sealed cylinder cover without contacting the top of the beef jerky sample. This makes the airflow between the beef jerky sample and the sliding push rod more complex and thorough, allowing for more comprehensive contact with all surfaces of the sample. This removes more moisture that has evaporated from the sample, further promoting uniform moisture loss and improving the accuracy of the test results. Attached Figure Description

A sealing cylinder cover 12 is hinged to the top of the weighing instrument 1 to close or open the heating coil 11 within the weighing instrument 1. Inside the sealing cylinder cover 12 is a dewatering assembly 2 for stably detecting the several beef jerky samples 13. The dewatering assembly 2 includes several sets of positioning pins 21 installed inside the sealing cylinder cover 12, and adjacent sets of positioning pins 21 are connected to a mounting frame 23. A rotating column 22 for driving the mounting frame 23 is rotatably connected inside the sealing cylinder cover 12. Between the rotating column 22 and the mounting frame 23 is a connecting plate 28 for fine-tuning the beef jerky samples 13 within the positioning pins 21 and a swing frame 24, with the swing frame 24 having a W-shaped structure.

[0040] Two sliders 25 are slidably connected to the side of the mounting bracket 23 near the rotating column 22. The two sliders 25 are used to drive the positioning pin 21 to move relative to or towards each other along one side of the mounting bracket 23. The two sliders 25 are connected together by an extension guide rod 27 and a return spring 26, and the return spring 26 is sleeved on the outside of the extension guide rod 27.

[0041] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, there are eight sets of positioning pins 21, and each set of positioning pins 21 contains two positioning pins 21. Similarly, there are eight sets of sliders 25, return springs 26, and guide rods 27, which are used in pairs. The positioning pins 21 are toothed. Furthermore, a servo motor is installed inside the sealing cylinder cover 12, and the output end of the servo motor is fixedly connected to the top of the rotating column 22, driving the rotating column 22 to rotate along the inside of the sealing cylinder cover 12. The guide rod 27 is a telescopic structure, and the guide rod 27 is located... The two sliders 25 are either contracted or extended towards the middle from both ends, and the presence of the guide rod 27 is used to limit the contraction of the return spring 26, preventing the return spring 26 from elastically bending and ensuring the stable movement of the two sliders 25; and the telescopic end of the electric push rod 35 is fixedly connected to the bottom of the slide 31, which is used to push the slide 31 to move along one side of the rotating column 22. The swing groove 32 is set with a corrugated structure, and the two ends of the swing groove 32 are in a horizontal state, so that the guide cone 33 is in the starting position at both ends of the swing groove 32, which is used to keep the slide 31 stable during movement.

[0042] refer to Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a swing push assembly 3 is provided on one side of the rotating column 22 to drive the connecting plate 28 to move. The swing push assembly 3 includes a concentric column 34 installed between the connecting plate 28 and the rotating column 22 and a slide 31 slidably connected to one side of the rotating column 22. The slide 31 slides along one side of the connecting plate 28. A guide cone 33 is installed on the top of the connecting plate 28. A swing groove 32 is opened on one side of the slide 31 to allow the guide cone 33 to move and swing. The swing groove 32 is set with a corrugated structure. An electric push rod 35 is installed on the side of the rotating column 22 near the slide 31. The output end of the electric push rod 35 is used to push the slide 31 to move up and down reciprocally.

[0043] The bottom end of the connecting plate 28 is provided with several threaded grooves 37, the top of the swing frame 24 is provided with a screw hole seat 36, and the screw hole seat 36 and the connecting plate 28 are kept in an inserted and uninserted state. An adjusting bolt 38 is screwed on the outside of the screw hole seat 36, and the adjusting bolt 38 is screwed into the threaded groove 37 corresponding to the screw hole seat 36 through the screw hole seat 36.

[0044] refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the number of threaded grooves 37 is set to 3, and the screw hole seat 36 is also provided with a screw hole for the adjusting bolt 38 to be screwed in. One end of the adjusting bolt 38 is screwed into the screw hole and is connected to one of the threaded grooves 37. Thus, the screw hole seat 36 and the connecting plate 28 are stably connected. Through the arrangement of the screw hole seat 36, threaded grooves 37, adjusting bolt 38, connecting plate 28 and swing frame 24, the indirect connection between the swing frame 24 and the beef jerky sample 13 can be adjusted, so that the swing frame 24 and the beef jerky sample 13 maintain stable contact, and ensure that the beef jerky sample 13 swings stably.

[0045] refer to Figure 4 , Figure 6 and Figure 7 As shown, a pressure plate assembly 4 that cooperates with the swing push assembly 3 is provided between the positioning pin 21 and the rotating column 22. The pressure plate assembly 4 includes a stabilizing sleeve 43 fixedly connected to one side of the rotating column 22. A shaft 45 is connected to one side of each of the two sliders 25. Two pressure plate arms 41 are movably sleeved on the outside of the two shafts 45. A shaft column 42 is sleeved between the two pressure plate arms 41. A force push rod 44 is fixedly connected to one end of the shaft column 42, and one end of the force push rod 44 passes through the stabilizing sleeve 43 and abuts against the bottom end of the electric push rod 35.

[0046] refer to Figure 7 , Figure 8 and Figure 9As shown, a push assembly 5 is provided between the sealing cylinder cover 12 and the positioning pin 21 to stably place the beef jerky sample 13 inside the weighing instrument 1 in the middle. The push assembly 5 includes a guide frame 51 fixedly connected inside the sealing cylinder cover 12 and a block 55 slidably connected to one side of the guide frame 51. A rotating disk 53 is rotatably connected inside the sealing cylinder cover 12. A rocking shaft arm 54 is installed at one end of the rotating disk 53. A servo motor 52 is fixedly connected to the outside of the sealing cylinder cover 12 and is used to drive the rotating disk 53 to rotate. A sliding push rod 56 is movably connected to one side of the block 55 and is set as an inverted T-shaped structure. The sliding push rod 56 is movably sleeved on one end of the rocking shaft arm 54. A column 57 is installed at the bottom end of the block 55 and a guide plate 58 is fixedly connected to the bottom end of the column 57. The guide plate 58 is used to guide the beef jerky sample 13 to the middle position of the weighing instrument 1.

[0047] refer to Figure 7 , Figure 8 and Figure 9 As shown, a flow-reversing assembly 6 is provided on one side of the guide frame 51 to drive the column 57 to rotate. The flow-reversing assembly 6 includes an attachment frame 61 fixedly connected to the bottom of the guide frame 51. A stabilizing column 63 is connected between the connecting block 55 and the column 57. A positioning groove 62 for the stabilizing column 63 to move is opened on one side of the attachment frame 61. A flipping groove 67 communicating with the inside of the positioning groove 62 is opened at the top of the attachment frame 61. A semi-rocker 64 is installed on the outside of the stabilizing column 63, and the semi-rocker 64 is located inside the positioning groove 62 and the flipping groove 67. A gear 65 is fixedly sleeved on the outside of the stabilizing column 63. A rack 66 that meshes with the gear 65 is fixedly connected to the bottom of the attachment frame 61. The receiving guide plate 58 is set with a shovel-shaped structure to ensure that the bottom of the beef jerky sample 13 is changed to an inclined shape after contacting the receiving guide plate 58.

[0048] refer to Figure 7 , Figure 8 and Figure 9 As shown, the guide plate 58, the semi-rocker 64, the gear 65 and the rack 66 are arranged so that the guide plate 58 can maintain a corresponding state with the guide frame 51 inside the sealing cylinder cover 12 when not in use. This facilitates the storage of the guide plate 58 inside the sealing cylinder cover 12. Furthermore, the guide plate 58 is located at the corner inside the sealing cylinder cover 12, which reduces the interference caused by the airflow inside the sealing cylinder cover 12 and ensures that the air inside the sealing cylinder cover 12 flows relatively smoothly.

[0049] Working principle:

[0050] When using;

[0051] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when testing the moisture content of the same dried beef sample and evaporation is required, firstly, the sealing cylinder cover 12 is slowly folded open along the top of the weighing instrument 1. At this time, the rotating column 22 and the positioning pin 21, which were originally hidden inside the sealing cylinder cover 12, will be revealed. Then, the prepared dried beef sample 13 is carefully placed between the two positioning pins 21. At the moment of placement, the sample will come into contact with the two positioning pins 21. Subsequently, due to this contact, the two positioning pins 21 will drive the two connected sliders 25 to move relative to each other along one side of the mounting bracket 23. When this external force disappears, the return spring 26 will drive the two sliders 25 to move towards each other based on its own elasticity. This will cause the two positioning pins 21 to generate a reaction force under the action of the two sliders 25. In this way, it can be ensured that the outside of the sample and the two positioning pins 21 always maintain a stable contact state.

[0052] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, following subsequent operations, the sample is securely restrained at both ends by two adjacent sets of positioning pins 21 inside the sealing cylinder cover 12. This ensures the sample remains stable within the sealing cylinder cover 12, preventing easy displacement. After all samples are accurately secured inside the sealing cylinder cover 12 by the positioning pins 21, the sealing cylinder cover 12 is slowly pushed back, re-sealing it with the weighing instrument 1. After this process, the heating coil 11 begins to generate heat, which gradually spreads into the sealing cylinder cover 12, drying the sample before formal testing. It is worth noting that each drying process... During the drying process, all operations can be performed according to uniform standard conditions, such as setting specific temperatures and specifying specific durations. Through this standardized processing method, it can be ensured that all samples to be tested are in a standardized drying state, providing a unified benchmark for subsequent testing work and greatly ensuring the accuracy and consistency of test results. Finally, inside the sealed cylinder cover 12, the servo motor starts to run, driving the rotating column 22 to rotate. Through the rotation of the rotating column 22, different parts of the sample can be fully exposed to heat, thereby achieving comprehensive and uniform drying treatment of different parts of the sample, allowing the drying effect of the sample to reach the optimal state, and laying a good foundation for subsequent accurate moisture detection.

[0053] refer to Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, after both ends of the sample reach an adaptive clamping state with the positioning pin 21, if it is necessary to intermittently separate one end of the sample from the positioning pin 21 and form a slight swing, the following series of linkage operations will be triggered. First, the electric push rod 35 begins to extend and retract, and its extension and retraction will drive the swing groove 32 to slowly move downward along one side of the rotating column 22. During this process, one side of the swing groove 32 will closely fit one side of the connecting plate 28 and move along its guide. At the same time, the inside of the swing groove 32 will move along the outside of the guide cone 33. As the movement continues, the guide cone 33... It will gradually slide out of the horizontal position inside the swing groove 32, and then move towards the corrugated interior of the swing groove 32. At this stage, the interior of the swing groove 32 will come into contact with the exterior of the guide cone 33. This contact force will push the guide cone 33 to move along the interior of the swing groove 32 according to the guide. This movement of the guide cone 33 inside the swing groove 32 is not unidirectional, but will swing back and forth. With the back and forth swing of the guide cone 33, it will drive the connecting plate 28 to make lever movement along the exterior of the concentric column 34, and then make the connecting plate 28 also start to swing back and forth along one side of the rotating column 22.

[0054] refer to Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, during this process, another set of linked actions is also performed simultaneously. As the electric push rod 35 moves downwards, it comes into contact with the top of the force push rod 44. The force generated by this contact pushes the force push rod 44 downwards along the interior of the stabilizing sleeve 43. Immediately afterwards, the movement of the force push rod 44 pushes the shaft column 42 upwards in sync. As the shaft column 42 moves upwards, its exterior comes into contact with the interior of the two pressure arm 41. This contact force drives the two pressure arm 41 downwards. During the downward movement of the two pressure arm 41, the angle between them and the shaft column 42 gradually increases, and the tilt amplitude of the two pressure arm 41 is adjusted accordingly. Subsequently, the two pressure arm 41 continue to move downwards, generating a thrust on the two shaft rods 45. Under the action of this thrust, the two shaft rods... The two shafts 45 will move relative to each other, and the movement of the two shafts 45 will drive the two connected sliders 25 and the two positioning pins 21 to move synchronously. In this way, a certain floating distance will be maintained between the two positioning pins 21 and the bottom of the beef jerky sample 13. Then, as the connecting plate 28 is swinging left and right, it will drive the connected swing frame 24 to move synchronously. One end of the swing frame 24 will come into contact with the beef jerky sample 13 and push the beef jerky sample 13 to make a slight displacement within the positioning pin 21. Moreover, during the swinging process, the other end of the swing frame 24 will also come into contact with one side of the beef jerky sample 13 and push the beef jerky sample 13 again. In this way, through the above series of actions, the beef jerky sample 13 can finally swing slightly within the positioning pin 21.

[0055] refer to Figure 7 , Figure 8 and Figure 9As shown, when faced with the situation where the dried beef jerky sample 13 needs to be pushed out along the inside of the positioning pin 21 and stably placed in the middle of the weighing instrument 1, firstly, the servo motor 52 starts to rotate. Driven by the motor, the rotating disk 53 connected to it will rotate synchronously. As the rotating disk 53 rotates, the swing shaft arm 54 connected to it will also rotate synchronously. At this time, the swing shaft arm 54 will make a circular motion along one end of the servo motor 52. Then, the movement of the swing shaft arm 54 will drive the sliding push rod 56 to move upward along one side of the receiving block 55. During the movement, the bottom end of the sliding push rod 56 will gradually maintain a horizontal state with the bottom of the receiving block 55 until the upward distance of the sliding push rod 56 reaches its maximum. Subsequently, as the swing shaft arm 54 continues to rotate, it will drive the sliding push rod 56 to start moving horizontally. Under the action of the horizontal movement of the sliding push rod 56, the receiving block 55... The 5 will move horizontally along one side of the guide frame 51 and gradually approach the top of the beef jerky sample 13. Then, with the further rotation of the swing shaft arm 54, the sliding push rod 56 will be pushed to move downward. At this time, the sliding push rod 56 will slowly move downward along one side of the receiving block 55 until the sliding push rod 56 comes into contact with the bottom of the beef jerky sample 13, thereby pushing the beef jerky sample 13. After that, the receiving guide plate 58 begins to play its role. It is used to contact the bottom of the beef jerky sample 13. Due to structural and positional factors, the bottom of the beef jerky sample 13 and the receiving guide plate 58 will maintain an inclined state. With this state and the guiding effect of the receiving guide plate 58, the beef jerky sample 13 can smoothly slide out from the inside of the positioning pin 21 and, under the guidance of the receiving guide plate 58, move towards the middle position of the weighing instrument 1, finally achieving the purpose of being stably placed in the middle of the weighing instrument 1.

[0056] refer to Figure 7 , Figure 8 and Figure 9As shown, when the sliding push rod 56 drives the connecting block 55 to move horizontally along one side of the guide frame 51, and it is necessary to perform a flipping operation on the guide plate 58 so that it can better guide the beef jerky sample 13, the entire device will trigger the following series of actions. First, the movement of the guide frame 51 will drive the connected horizontal stabilizer 63, the semi-rocker 64 and the gear 65 to move synchronously. Then, the outside of the semi-rocker 64 will start to move along the inside of the positioning groove 62 towards the inside of the flipping groove 67. Before the semi-rocker 64 has finished moving... During the process of moving fully into the tilting slot 67, its moving posture remains unchanged, maintaining its initial state. Subsequently, the semi-cradle 64 continues to move deeper into the tilting slot 67 along the positioning slot 62. Once inside the tilting slot 67, the semi-cradle 64 is freed from the original constraint of the positioning slot 62. Immediately afterwards, the gear 65 meshes with the rack 66. Driven by this meshing action, the semi-cradle 64 begins to rotate around a certain axis. As the semi-cradle 64 continues to rotate, it will move along... The interior of the tilting groove 67 rotates synchronously, and its original posture changes accordingly. When the semi-rocker 64 rotates along the tilting groove 67 until it is horizontal again with the positioning groove 62, the semi-rocker 64 moves back along the tilting groove 67 and re-enters the interior of the positioning groove 62. At this time, the gear 65 and the rack 66 disengage accordingly. After this, the semi-rocker 64 continues to maintain horizontal displacement under the action of the positioning groove 62. Meanwhile, due to the rotation of the semi-rocker 64, It will also cause the connected stabilizing column 63 to rotate synchronously, and the rotation of the stabilizing column 63 will cause the column 57 to move accordingly, thereby causing the receiving guide plate 58 to rotate along one side of the receiving block 55. Through this rotation process, the relative state between the receiving guide plate 58 and the receiving block 55 will change from the original vertical state to the vertical state, and finally realize that the receiving guide plate 58 corresponds to the middle position of the weighing instrument 1, so as to better guide the beef jerky sample 13 and make it accurately placed in the middle area of ​​the weighing instrument 1.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
