Description

Technical Field

[0001] This invention relates to the field of thickness measurement technology, specifically to a device for detecting the thickness of sliced ​​beef and mutton. Background Technology

[0002] The thickness inspection of beef and mutton slices is primarily to ensure the taste and texture of the meat. Different types and cuts of meat have specific thickness standards. In practice, beef and mutton slicers can adjust the slice thickness as needed, typically between 0 and 15 millimeters. Appropriate slice thickness is crucial for guaranteeing the taste and texture of beef and mutton. Different meat qualities and requirements necessitate different thickness standards; therefore, thickness inspection devices are needed during beef and mutton slice production to verify whether the produced slices meet the required thickness standards.

[0003] Existing thickness detection devices for sliced ​​beef and mutton obtain their thickness by directly installing a visual recognition system on the production line or by using a laser ranging module to detect the sliced ​​beef and mutton moving at the bottom. However, because some slices are not completely in contact with the conveyor belt surface, or because two slices are stacked, the subsequent detection data will be biased, thus reducing the reliability of the detection data. Moreover, it is difficult to efficiently eliminate the above problems. On the other hand, with the laser ranging scheme, the actual measurement range is all on a straight line. Therefore, the thickness of other areas on the side of the sliced ​​beef and mutton that are not irradiated by the laser module cannot be detected, thus limiting the detection range. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a beef and mutton slice thickness detection device to solve the problems mentioned in the background art. The present invention can ensure that the bottom of the beef and mutton slice is in contact with the surface of the conveyor belt during the thickness detection process, so that the final thickness data is more accurate and reliable. It can also solve the problem of stacking two or more beef and mutton slices, and automatically detect and process the stacked beef and mutton slices one by one. Moreover, the two detection components work together to expand the thickness detection range to any area of ​​each beef and mutton slice.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a thickness detection device for beef and mutton slices, comprising a thickness detection device body, the thickness detection device body including a support frame and a detection mechanism, a first conveyor belt and a second conveyor belt being constructed at the bottom of the support frame, and a docking platform being embedded between the first and second conveyor belts, the surface of the docking platform being embedded with a photosensitive module, the detection mechanism including a leveling component, a first detection component and a second detection component, an electric lifting rod being screwed to the bottom of the support frame, a lifting plate being welded to the bottom end of the electric lifting rod, the second detection component being installed below the lifting plate, a lifting column being welded to one end of the lifting plate, the first detection component being welded to the inner side of the lifting column, a rectangular groove being formed on the inner wall of the lifting column, and limit blocks being integrally formed at both ends of the leveling component, the limit blocks being embedded in the groove on the inner wall of the lifting column.

[0006] Furthermore, the first detection component includes a first laser module and a linkage plate. The inner wall of the lifting column is welded with an inner convex plate. The first laser module is screwed to the middle position of the inner convex plate. A spring rod is welded to the top of the linkage plate.

[0007] Furthermore, the top of the spring rod passes upward through the end of the inner convex plate, and the two ends of the spring on the spring rod are welded and fixed to the surfaces of the inner convex plate and the linkage plate, respectively. A first reflective sheet is embedded in the middle of the surface of the linkage plate, and the end of the linkage plate abuts against the inner wall of the lifting column.

[0008] Furthermore, the leveling component includes a pressing roller and an arc-shaped patch, and a connecting column is welded to the bottom of the linkage plate, and an arc-shaped patch is welded to the bottom of the connecting column.

[0009] Furthermore, the two ends of the pressing roller are fitted with plug plates, the limiting block is integrally formed on the top of the plug plates, and the bottom of the arc-shaped patch is attached to the top of the pressing roller.

[0010] Furthermore, the bottom of both ends of the lifting plate is integrally formed with a lower hanging plate, and a lead screw and a guide rod are inserted through the inner wall of the lower hanging plate. A threaded sleeve is sleeved on the surface of the lead screw, and a linkage column is integrally formed on both sides of the threaded sleeve. A guide sleeve is integrally formed at the end of the linkage column.

[0011] Furthermore, the end of the lead screw and both ends of the guide rod are embedded into the lower hanging plate through bearings, and a motor is installed at the other end of the lead screw. The outer shell of the motor is fixed to the surface of the lower hanging plate with screws. The guide sleeve is sleeved on the surface of the guide rod, and the guide rod and the lead screw are parallel to each other.

[0012] Furthermore, the second detection component includes a second laser module and a bonding plate. A column is welded to the bottom of the threaded sleeve, and a detection plate is integrally formed at the bottom of the column. Through holes are opened at both ends of the detection plate, and the second laser module is screwed to the bottom of the detection plate.

[0013] Furthermore, a pin is welded to the bottom of the guide sleeve, a second reflective sheet is embedded in the middle of the surface of the bonding plate, a lifting sleeve is welded to the top of the bonding plate, and the pin passes through the inside of the lifting sleeve.

[0014] Furthermore, the lifting sleeve extends upward from the inside of the top through hole, and a convex limiting ring structure is provided on the outer side of the top of the lifting sleeve. One end of the lifting plate is perpendicular to the side of the lifting column, and the second laser module irradiates towards the center point of the second reflector.

[0015] The beneficial effects of this invention are:

[0016] 1. After detecting the entry of beef and mutton slices into the bottom of the slice, the beef and mutton slice thickness detection device controls the entire detection mechanism to move downward. Through the second detection component and the leveling component, it ensures that the bottom of the beef and mutton slice is in contact with the surface of the conveyor belt during the thickness detection process. This avoids the problem of some beef and mutton slices lifting up at the bottom, which would lead to an overestimation of the thickness detection result, and makes the final thickness data more accurate and reliable.

[0017] 2. This beef and mutton slice thickness detection device addresses the issue of stacked beef and mutton slices. A second detection component is embedded into the edge of the bottom layer of beef and mutton slices, pulling the slice along. A leveling component then blocks another unattached slice from the stack, preventing it from passing through the detection mechanism. This process continues until the first slice is detected. Once the detection mechanism is lifted, subsequent separated slices can be detected, thus achieving automatic, sequential detection and processing of stacked beef and mutton slices.

[0018] 3. The beef and mutton slice thickness detection device uses two detection components working together. The second detection component is inserted into a fixed point on the surface of the beef and mutton slice and pulled, while the first detection component is kept in a fixed position and applies uniform pressure to the bottom of the beef and mutton slice as it moves across. Therefore, if the beef and mutton slice itself is stacked or there are foreign objects underneath, the thickness abnormality can be detected when the foreign objects move across the second detection component, and the thickness detection range can be expanded to any area of ​​each beef and mutton slice.

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] Please see Figures 1 to 7The present invention provides the following technical solution: a thickness detection device for beef and mutton slices, comprising a thickness detection device body, the thickness detection device body comprising a support frame 3 and a detection mechanism 4, a first conveyor belt 1 and a second conveyor belt 2 being constructed at the bottom of the support frame 3, and a docking platform 6 being embedded between the first conveyor belt 1 and the second conveyor belt 2, the surface of the docking platform 6 being embedded with a photosensitive module 7, the detection mechanism 4 comprising a leveling component 12, a first detection component 11 and a second detection component 13, an electric lifting rod 5 being screwed to the bottom of the support frame 3, a lifting plate 8 being welded to the bottom end of the electric lifting rod 5, the second detection component 13 being installed below the lifting plate 8, a lifting column 10 being welded to one end of the lifting plate 8, the first detection component 11 being welded to the inner side of the lifting column 10, a rectangular groove being formed on the inner wall of the lifting column 10, and limiting blocks 37 being integrally formed at both ends of the leveling component 12, the limiting blocks 37 being embedded in the groove on the inner wall of the lifting column 10. This beef and mutton slice thickness detection device is used to detect the thickness of beef and mutton slices after slicing on the production line, and automatically handles problems such as wrinkles and curling of individual beef and mutton slices or stacking of multiple beef and mutton slices during the detection process.

[0029] In use, the beef and mutton slices are conveyed along the first conveyor belt 1 towards the rear end. After being transferred to the docking platform 6, they directly cover the bottom photosensitive module 7, allowing detection of the beef and mutton slices at that position. The top electric lifting rod 5 is then activated, pressing the entire detection mechanism 4 downwards until the leveling component 12 is pressed onto the surface of the beef and mutton slice. The second detection component 13 is then embedded into the edge of the beef and mutton slice. Finally, the motor 14 is activated, and the second detection component 13 is used to separate the beef and mutton slices. The meat slicer is pulled and pressed and leveled by the leveling component 12. During the movement of the meat slicer, the thickness of the meat slicer at the insertion position can be accurately measured by the second detection component 13. At the same time, the first detection component 11 can be used to detect whether other areas of the meat slicer are flat. After the measurement process of the meat slicer is completed, the electric lifting rod 5 can be controlled again to pull the detection mechanism 4 up and reset the second detection component 13. The above process can be repeated to continue the detection.

[0030] In this embodiment, the first detection component 11 includes a first laser module 29 and a linkage plate 30. An inner convex plate 28 is welded to the inner wall of the lifting column 10. The first laser module 29 is screwed to the middle position of the inner convex plate 28. A spring rod 31 is welded to the top of the linkage plate 30. The top of the spring rod 31 passes upwards from the end of the inner convex plate 28, and both ends of the spring on the spring rod 31 are welded and fixed to the surfaces of the inner convex plate 28 and the linkage plate 30, respectively. A first reflective sheet 33 is embedded in the middle of the surface of the linkage plate 30, and the end of the linkage plate 30 abuts against the inner wall of the lifting column 10. Specifically, the first laser module 29 illuminates the first reflective sheet 33. Since the bottom of the first detection component 11 is constantly pressed against the surface area of ​​the beef and mutton slice to be tested by the pressing roller 32, the thickness change of the beef and mutton slice is converted into the amplitude change of the up-and-down overturning of the pressing roller 32. The first laser module 29 continuously detects the surface position of the linkage plate 30. Therefore, by obtaining the amplitude change of the distance between the linkage plate 30 and the first laser module 29, it can be determined whether the beef and mutton slice that has been moved at the bottom has folds or foreign objects pressed on it. If the beef and mutton slice... If a fold or foreign object is found at the bottom, the foreign object will move past the bottom of the pressing roller 32 and lift the pressing roller 32 significantly. This, in conjunction with the arc-shaped patch 35 and the connecting post 34, will lift the linkage plate 30. The first laser module 29 will then detect a sudden and significant decrease in the spacing data. At this point, it can be determined that there is a foreign object at the bottom of the beef or mutton slice or that the slice itself has folded. This structure can also be used to detect uneven thickness of a single beef or mutton slice. Therefore, even if the thickness difference at any point on the edge of the beef or mutton slice is too large, it will interfere with the pressing effect of the pressing roller 32 and will be detected.

[0031] In this embodiment, the leveling component 12 includes a pressing roller 32 and an arc-shaped patch 35. A connecting column 34 is welded to the bottom of the linkage plate 30, and an arc-shaped patch 35 is welded to the bottom of the connecting column 34. Insertion plates 36 are inserted into both ends of the pressing roller 32. A limiting block 37 is integrally formed on the top of the insertion plate 36, and the bottom of the arc-shaped patch 35 is in contact with the top of the pressing roller 32. Two detection components work together. The second detection component 13 is inserted into a fixed point on the surface of the beef and mutton slice and pulled, while the first detection component 11 maintains a fixed position and applies uniform pressure to the bottom of the beef and mutton slice as it moves. Therefore, if the beef and mutton slice itself is stacked or there are foreign objects underneath, the thickness abnormality can be detected when the foreign object moves past the second detection component 13, and the thickness detection range can be extended to any area of ​​each beef and mutton slice.

[0032] Specifically, when multiple beef and mutton slices are stacked together, since the second detection component 13 can only be inserted at the outermost edge, as long as the two beef and mutton slices are not completely aligned at the edge, it can be ensured that when the second detection component 13 is used to pull, only one beef and mutton slice can be pulled for movement and detection. The other stacked beef and mutton slices will be blocked by the pressing roller 32, which will prevent them from moving synchronously. Therefore, the phenomenon of unreliable detection data caused by the synchronous movement of multiple beef and mutton slices can be avoided.

[0033] In this embodiment, the bottom ends of the lifting plate 8 are integrally formed with lower hanging plates 9. A lead screw 15 and a guide rod 16 are inserted into the inner wall of the lower hanging plate 9. A threaded sleeve 17 is fitted on the surface of the lead screw 15. Linkage columns 18 are integrally formed on both sides of the threaded sleeve 17. A guide sleeve 19 is integrally formed at the end of the linkage column 18. The end of the lead screw 15 and both ends of the guide rod 16 are embedded into the lower hanging plate 9 through bearings. A motor 14 is installed at the other end of the lead screw 15. The outer shell of the motor 14 is fixed to the surface of the lower hanging plate 9 with screws. The guide sleeve 19 is fitted on the surface of the guide rod 16, and the guide rod 16 and the lead screw 15 are parallel to each other. To address the issue of stacked beef and mutton slices, the second detection component 13 is embedded into the edge of the bottom beef and mutton slice and pulled. The leveling component 12 then blocks another unconnected beef and mutton slice from the stack, preventing it from passing through the detection mechanism 4. After the first beef and mutton slice has been detected, the detection mechanism 4 is lifted again to detect and process the subsequently separated beef and mutton slices. This achieves the effect of automatically detecting and processing the stacked beef and mutton slices one by one.

[0034] Specifically, after starting the motor 14, the motor 14 drives the lead screw 15 to rotate, the lead screw 15 drives the threaded sleeve 17 to move, and in turn drives the wire sleeves at both ends, as well as the bottom pin 25, column 20, and detection plate 21 to move. Since the electric lifting rod 5 at the top can simultaneously drive the entire detection mechanism 4 to move up and down, after controlling the entire detection mechanism 4 to move down, the bottom pin 25 can be embedded into the edge of the beef and mutton slice below. At this time, starting the motor 14 can use the pull of the pin 25 to slide the entire beef and mutton slice along the docking platform 6 until it is moved to the surface of the second conveyor belt 2, where the thickness of the beef and mutton slice can be detected separately. During the detection, the bonding plate 23 will always press on the fixed area on the surface of the beef and mutton slice. Therefore, the thickness of the fixed point on the surface of the beef and mutton slice can be detected by the second laser module 22 at the top. The pressing effect of the bonding plate 23 ensures that the beef and mutton slice in the bottom detection area can remain in contact with the surface of the conveyor belt until the entire detection process is completed.

[0035] In this embodiment, the second detection component 13 includes a second laser module 22 and a bonding plate 23. A column 20 is welded to the bottom of the threaded sleeve 17, and a detection plate 21 is integrally formed at the bottom of the column 20. Through holes 26 are opened at both ends of the detection plate 21, and the second laser module 22 is screwed to the bottom of the detection plate 21. A pin 25 is welded to the bottom of the guide sleeve 19. A second reflective sheet 27 is embedded in the middle of the surface of the bonding plate 23, and a lifting sleeve 24 is welded to the top of the bonding plate 23. The pin 25 passes through the inside of the lifting sleeve 24. The lifting sleeve 24 extends upward from the inside of the through hole 26 at the top, and a protruding limiting ring structure is provided on the outer side of the top end of the lifting sleeve 24. One end of the lifting plate 8 is perpendicular to the side of the lifting column 10. The second laser module 22 irradiates the center point of the second reflective sheet 27. After detecting the bottom of the beef and mutton slices, the entire detection mechanism 4 is controlled to move downwards. The second detection component 13, in conjunction with the leveling component 12, ensures that the bottom of the beef and mutton slices is in contact with the surface of the conveyor belt during the thickness detection process. This avoids the problem of some beef and mutton slices lifting up at the bottom, which would lead to an overestimation of the thickness detection result, making the final thickness data more accurate and reliable.

[0036] Specifically, when the second detection component 13 is embedded at the edge of the beef and mutton slice and the beef and mutton slice is pulled, since the pressing roller 32 has already pressed on the surface of the beef and mutton slice and the pressing roller 32 does not move synchronously with the horizontal movement of the beef and mutton slice, when the beef and mutton slice is pulled out from the bottom of the pressing roller 32, the pressure provided by the pressing roller 32 can be used to flatten the beef and mutton slice. Therefore, for some beef and mutton slices that are warped inside and attached to the surface of the conveyor belt, or for folds and small foreign objects at the bottom, the pressing and pushing process can achieve the purpose of flattening.

[0037] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
