Description

Technical Field

[0001] The present invention relates to the technical field of sampling devices, and more particularly to a sampling device for detecting meat tenderness. Background Art

[0002] In the field of meat tenderness detection, sampling the meat is a crucial step to obtain accurate data. However, in the actual sampling process, the handling of mutton fascia has always troubled the relevant workers. Mutton fascia is not only tough but also tightly attached, making it difficult to separate it from the meat during sampling.

[0003] Traditional methods for removing mutton fascia usually require a large amount of time and effort. Since the fascia in mutton is complexly distributed and tightly connected to the muscle, manually removing the fascia not only requires high professional skills but also is very time-consuming and laborious. For example, in a laboratory environment, technicians need to spend a lot of time carefully separating the fascia and muscle to obtain muscle samples for tenderness detection, which seriously affects the sampling efficiency. Moreover, the meat contains certain moisture and viscous substances such as proteins and fats. When the meat is cut, these viscous substances will be exposed on the surface, making the meat slices easily adsorb to each other, resulting in adhesion. The temperature of the meat also affects the adhesion situation. If the temperature of the meat is relatively low, the fat in it will become more viscous, further increasing the possibility of meat slice adhesion, thus increasing the sampling difficulty. How to invent a sampling device for detecting meat tenderness to solve these problems has become an urgent problem for those skilled in the art. Summary of the Invention

Detailed implementation manners

[0019] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Example, refer to Figures 1-8 , a sampling device for detecting meat tenderness, including a conveying rack 1 and a bearing platform 8. The bearing platform 8 is connected with a conveyor belt 4. A discharging seat 9 is arranged inside the conveying rack 1. A pressing roller 6 and a cutting blade 7 are arranged on the inner side of the conveying rack 1. The conveying rack 1 is connected with an adjusting component 3. It also includes: A driving component 2, the driving component 2 is connected with the conveying rack 1, and the driving component 2 is used to prevent the cutting blade 7 from sticking. A conveying component 5, the conveying component 5 is connected with the conveying rack 1, and the conveying component 5 is used to promote the conveying of meat.

[0021] Furthermore; the conveying rack 1 is fixedly connected with the bearing platform 8 and the discharging seat 9 respectively. The bearing platform 8 is located above the discharging seat 9. The bearing platform 8 is located below one of the conveyor belts 4. A docking slot hole 101 is opened on the side wall of the conveying rack 1. The adjusting component 3 includes a fixing plate 35. The fixing plate 35 is fixedly connected with the conveying rack 1. A limiting frame 32 is fixedly connected to the side wall of the fixing plate 35. A second motor 31 is arranged at the upper end of the limiting frame 32. A buffer spring 34 and a lead screw 36 are arranged inside the limiting frame 32. The lead screw 36 is threadedly connected with a connecting plate 33. The connecting plate 33 is arranged in an "L" shape. The connecting plate 33 is slidably connected with the limiting frame 32. One end of the connecting plate 33 is rotatably connected with the pressing roller 6. The buffer spring 34 is sleeved on the outer wall of the lead screw 36. The two ends of the buffer spring 34 are respectively fixedly connected with the side wall of the connecting plate 33 and the fixing plate 35. One end of the lead screw 36 is rotatably connected with the side wall of the fixing plate 35. The other end of the lead screw 36 penetrates through the side wall of the limiting frame 32 and is fixedly connected with the second motor 31.

[0022] Adjustment of the adjusting component 3 for meats of different thicknesses: The adjusting component 3 is mainly composed of a fixing plate 35, a limiting frame 32, a second motor 31, a buffer spring 34, a lead screw 36, etc. When the second motor 31 is started, it drives the lead screw 36 to rotate. Since the lead screw 36 is threadedly connected with the connecting plate 33, and the connecting plate 33 is in an "L" shape and is slidably connected with the limiting frame 32, the rotation of the lead screw 36 will cause the connecting plate 33 to slide up and down in the limiting frame 32. The buffer spring 34 is sleeved on the outer wall of the lead screw 36, and its function is to buffer the movement of the connecting plate 33 to avoid excessive extrusion of the meat by the pressing roller 6. When it is necessary to adapt to meats of different thicknesses, by controlling the forward and reverse rotation of the second motor 31, the rotation direction and number of turns of the lead screw 36 are adjusted, and then the height of the pressing roller 6 is accurately adjusted to ensure that appropriate pressure can be provided for meats of different thicknesses and ensure the stability of the meat during the conveying and cutting processes.

[0023] Refer to Figure 6 and Figure 7, further; the conveying assembly 5 includes a conveying roller 51, which is rotatably connected to the rotating shaft 23, and a plurality of placement grooves 53 distributed in a circumferential array are opened inside the conveying roller 51, and a plurality of movable holes 57 distributed in a linear array are opened on the inner wall of the placement groove 53, and a movable plate 52 is slidably connected to the inner wall of the placement groove 53, and a plurality of evenly distributed return springs 55 are fixedly connected to one side of the movable plate 52, and the end of the return spring 55 away from the movable plate 52 is fixedly connected to the inner wall of the placement groove 53, and the side wall of the movable plate 52 is fixedly connected to a displacement sensor 56, and the displacement sensor 56 is located on the inner side of one of the return springs 55; the conveying assembly 5 also includes a movable rod 54, which is arranged in a "T" shape, and one end of the movable rod 54 passes through the movable hole 57 and is fixedly connected to the side wall of the movable plate 52, and the other end of the movable hole 57 is fixedly connected to the bristles 541.

[0024] The conveying roller 51 increases the stability during cutting: when the meat moves on the conveying roller 51, pressure is generated on the movable plate 52 through the movable rod 54, causing the movable plate 52 to compress the return spring 55. The elastic action of the return spring 55 can be adaptively adjusted according to the weight and shape of the meat, always providing a stable supporting force for the meat. If the meat is heavier, the return spring 55 will be compressed more severely, but at the same time it will also produce a greater reverse elastic force, causing the movable rod 54 to press tightly against the meat to prevent it from shaking during the conveying process; for lighter meat, the compression degree of the return spring 55 is smaller, and the supporting force provided is relatively moderate, which can also ensure the stability of the meat. In the process of the movable plate 52 moving with the meat, the movable rod 54 will move synchronously, driving the brush 541 to clean the surface of the meat. The brush 541 can remove impurities, debris and substances that may cause the meat slices to stick together on the surface of the meat, thereby reducing the problem of unstable conveying caused by unclean or sticky surfaces. During the cleaning process, the brush 541 can also It can play a certain role in limiting and straightening the meat, ensuring that the meat maintains the correct position in the placement groove 53, further improving the stability of transportation, and the bristles 541 can be made of food-grade silicone, which usually has good high-temperature resistance to ensure the normal use of the bristles 541 under heated conditions, and the movable rod 54 as a whole has an electric heating function, and heating wires can be set inside. These heating wires are made of high-temperature resistant, corrosion-resistant and thermally conductive materials to ensure stable heating during long-term use without contaminating the meat. In addition, in order to achieve accurate temperature control, a high-precision temperature sensor can be set on the movable rod 54, which can monitor the temperature changes of the movable rod 54 in real time and feed back the data to the external controller connected to it. The outside of the movable rod 54 is wrapped with a layer of high-efficiency heat-insulating material. This layer of heat-insulating material can effectively reduce heat loss and improve energy utilization efficiency. At the same time, it prevents operators from being scalded by contact with the movable rod 54, thereby ensuring the safety of operation. A displacement sensor 56 is fixedly connected to the side wall of the movable plate 52, which can monitor the displacement changes of the movable plate 52 in real time. Since the displacement of the movable plate 52 is related to factors such as the weight and thickness of the meat, when the position of the displacement sensor 56 changes, the acquired data can be fed back to the control system of the entire sampling device. The control system can adjust the temperature emitted by the movable rod 54 according to these data, and can trigger the movable rod 54 to heat the meat when the position of the displacement sensor 56 changes. The heat is conducted to its surface through the material of the movable rod 54. Since the movable rod 54 is in close contact with the meat sample, the heat can be quickly transferred to the meat. For some meats with a high fat content, proper heating can soften the fat, reduce its viscosity, effectively reduce the adhesion between meat slices, make the cutting process smoother, and improve sampling efficiency. When cutting mutton, the fat in the mutton becomes easy to separate after heating, and the debris generated during cutting is significantly reduced, which not only improves the cutting quality but also reduces the loss of the cutting blade 7.

[0025] Reference Figure 3 、 Figure 4 and Figure 8 , further; the cutting blade 7 is located on one side of one of the conveyor belts 4, one end of the cutting blade 7 is detachably connected to the docking slot 101, a through slot 72 is provided inside the cutting blade 7, the upper side wall of the cutting blade 7 is fixedly connected to a plurality of convex strips 71 distributed in a linear array, and the inner wall of the cutting blade 7 is provided with a plurality of exhaust holes 73 distributed in a linear array; the buffer spring 34 is sleeved on the outer wall of the screw rod 36, and the two ends of the buffer spring 34 are respectively fixedly connected to the side walls of the connecting plate 33 and the fixing plate 35, and one end of the screw rod 36 is fixed to the fixing plate 35 The side wall of the wind collecting cover 24 is rotatably connected, and the other end of the screw rod 36 passes through the side wall of the limit frame 32 and is fixedly connected to the motor 2 31; the driving assembly 2 also includes a wind collecting cover 24, which is fixedly connected to the side wall of the conveying frame 1, and one end of the wind collecting cover 24 is connected to the docking slot 101. The side wall of the wind collecting cover 24 is rotatably connected to a rotating rod 28, and one end of the rotating rod 28 located inside the wind collecting cover 24 is fixedly connected to the turbine fan blade 27, and the other end of the rotating rod 28 is fixedly connected to the driven gear disc 25, and the driven gear disc 25 and the active gear disc 22 are connected through a toothed belt 26.

[0026] The cutting blade 7 is used to prevent the meat from sticking: the cutting blade 7 is located on one side of the conveying roller 51 and is detachably connected to the conveying frame 1 through the docking slot 101, which is convenient for replacement and maintenance. The through slot 72 inside the cutting blade 7, the ridge 71 on the upper side wall and the exhaust hole 73 on the inner wall all have specific functions. When cutting, the ridge 71 can increase the friction between the blade and the meat, making the cutting smoother, and the through slot 72 helps to reduce the weight of the blade and improve the cutting efficiency. When cutting meat, the motor 21 can be started to drive the rotating shaft 23 to rotate, thereby rotating the active gear disc 22 fixed on the rotating shaft 23. The active gear disc 22 is connected to the driven gear disc 25 through the toothed belt 26, driving the driven gear disc 25 to rotate. The driven gear disc 25 is mounted on the rotating rod 28, and the rotating rod 28 is located in the wind collecting cover 24, and the turbine fan blade 27 at one end thereof rotates accordingly. When the blades 27 are in motion, the turbine blades 27 rotate to generate airflow, which passes through the end of the wind collecting cover 24 connected to the docking slot 101, blows to the inside of the through slot 72, and is finally discharged from the exhaust hole 73, thereby generating airflow between the cutting blade 7 and the cut meat, which can effectively prevent the cutting blade 7 from sticking, thereby ensuring the cutting performance and service life of the cutting blade 7. Therefore, when cutting meat, the cutting blade 7 can accurately cut the transported meat under the coordinated action of the driving component 2, thereby avoiding the situation where the meat sticks to the blade and improving the cutting effect. The transmission ratio between the active toothed disc 22 and the driven toothed disc 25 can be adjusted according to the situation to ensure that there is sufficient wind force. In addition, part of the cut meat is transported to the surface of the supporting platform 8 through the conveyor belt 4, and the other part falls through the discharge seat 9 to achieve separation of the two.
