Description

Technical Field

[0001] The invention relates to the technical field of beef identification, in particular to a pretreatment device for beef identification. Background Art

[0002] Beef has firm texture and is full of flavor. With its high protein, low fat and good taste, it perfectly fits the contemporary consumer concept of pursuing quality and healthy eating. Therefore, it is widely sought after by consumers. Even though the price of beef is relatively expensive, consumers' enthusiasm for consumption continues to rise.

[0003] Due to the complex food processing technology, it is difficult for people to accurately judge the type and authenticity of food ingredients through intuitive methods such as looking, smelling and touching. At present, the identification of beef adulteration often uses a variety of methods such as mass spectrometry, spectral technology, sensor technology, and genetic technology. Among them, polymerase chain reaction can perform qualitative and quantitative detection of DNA with strong stability and high specificity, with high sensitivity and accuracy. Fluorescence quantitative PCR method can stably detect and quantitatively analyze samples.

[0004] In order to realize the above-mentioned detection and analysis, the obtained beef samples need to be pre-treated. Because the purchased raw meat samples have been placed for a certain period of time, many microorganisms are bred on their surfaces. In order to prevent the microorganisms on the surface of the raw meat samples from affecting the detection, the surface of the raw meat samples needs to be removed.

[0005] Because raw meat has great elasticity, the existing method of manually removing it with scissors is not convenient for fixing, which will make the cutting surface uneven during the cutting process, and easily cause the problem of incomplete removal of the surface of the raw meat sample. At the same time, the raw meat sample after the surface is removed will be exposed to the air. In order to minimize pollution as much as possible, rapid sampling is required. The meat blocks taken out by cutting in the existing technology are cumbersome to operate and are still prone to contamination.

[0006] Therefore, in view of the above problems, a pretreatment device for beef identification is proposed. Summary of the invention

[0007] The purpose of the present invention is to provide a pretreatment device for beef identification to solve the problem raised in the above background technology that "because raw meat has great elasticity, the existing manual removal method using scissors is not convenient for fixation, which will make the cutting surface uneven during the cutting process, easily resulting in incomplete removal of the surface of the raw meat sample and cumbersome operation process, and still prone to contamination."

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pretreatment device for beef identification, comprising an outer cylinder and an outer cutting knife, the inner center of the outer cylinder is slidably connected to an inner rod, the bottom end of the outer cylinder is rotatably connected to a plurality of arc covers through a hinge, the bottom end of the arc cover is fixedly connected to an arc ring, an operation window is opened on the inner side of the arc ring, a plurality of arc covers and arc rings can be spliced ​​inwardly, and a plurality of arc covers can be expanded outwardly, a torsion spring is fixedly connected between the top end of the arc cover and the bottom end of the outer cylinder, and the torsion spring provides elastic force for the arc cover to expand outwardly;

[0009] When a number of unfolded arc covers and arc rings are pressed down and brought close to the surface of raw meat, a bulge can be generated in the middle of the pressed area of ​​the raw meat, and the outer cutting knife is operated through the operating window to cut the bulge;

[0010] The bottom end of the inner rod is connected with an inner cutting knife, which can be tilted and vertical. After the protrusion is peeled off, the raw meat can be quickly sampled through the inner cutting knife.

[0011] The pretreatment device in the present invention is flexible and compact, easy to use and can achieve a good pollution-free sampling effect. Under the above settings, before the present invention is used, the device is disinfected and cleaned before use, and the raw meat is rinsed with physiological saline. When in use, first, a plurality of arc covers and arc rings are in an outwardly expanded state, and then a plurality of arc covers and arc rings are placed on the raw meat, and the plurality of arc covers and arc rings are always kept under downward pressure on the raw meat, and then the plurality of arc covers and arc rings are gradually spliced ​​inwardly and brought closer together. In the process of splicing and bringing closer together, the raw meat under the plurality of arc covers and arc rings will be squeezed, so that the raw meat will be bulged and tightened in the middle position of the downward pressure area, and the tightened raw meat will be easier to cut, and then the outer cutting knife is operated through the operation window. The cutting of the protrusions is realized, and finally the surface of the raw meat sample is cut. This cutting method can make the incision tight and neat, and avoids the problem that the manual removal method with scissors in the prior art is not convenient for fixing, which will make the cutting surface uneven during the cutting process, and easily cause the problem of incomplete removal of the surface of the raw meat sample. At the same time, because the arc cover and the arc ring are spliced ​​close together, a short-term relatively sealed environment is formed at the cutting place, ensuring a pollution-free environment for sampling. The set inner cutting knife starts to press down and cut for sampling, and also realizes rapid and continuous sampling, avoiding the raw meat sample after removing the surface from being exposed to the air for a long time. While being convenient and fast, it minimizes pollution and improves the accuracy of identification.

[0012] As a preferred pretreatment device for beef identification of the present invention, after the arc cover and the arc ring are spliced ​​and brought close together, the bottom end of the arc ring is inclined inwards.

[0017] When the swivel rotates, the swivel can move downward on the outer cylinder, and the swivel drives the pressure ring to move downward through the swivel and the connecting rod.

Then, the connecting rod drives the inner cutting knife to tilt inward. During the tilting process, the inner cutting knife still rotates through the inner rod, and continuously peels off the raw meat to be sampled.

[0027] Under the above setting, the lifting mode of the cone is that the motor rotates, and the motor drives the screw to rotate. Because the screw is spirally connected to the inner side of the cone, when the screw rotates, the cone can move upward or downward.

[0028] As a preferred pretreatment device for beef identification of the present invention, the outer side of the inner rod is also fixedly connected to a limiting rod, and the outer side of the limiting rod is slidably connected to the inner side of the cone cylinder to increase the stability of the cone cylinder when it is raised or lowered.

In the process of splicing and bringing closer, the raw meat under the plurality of arc covers and arc rings will be squeezed, so that the raw meat will be bulged and tightened in the middle position of the downward pressure area, and the tightened raw meat is easier to cut, and then the outer cutting knife is passed through The protrusions are cut through the operation window, and finally the surface of the raw meat sample is cut. This cutting method can make the incision tight and neat, and avoids the problem of uneven cutting surface during cutting due to the inconvenience of fixing in the prior art method of removing by scissors, which can easily cause the problem of incomplete removal of the surface of the raw meat sample. At the same time, because the arc cover and the arc ring are spliced ​​close together, a short-term relatively sealed environment is formed at the cutting position, ensuring a pollution-free environment for sampling.

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Example 1, please refer to Figure 1-Figure 4 and Figure 7-Figure 8 , the present invention provides a technical solution:

[0049] A pretreatment device for beef identification, comprising an outer cylinder 1 and an outer cutting knife 12, wherein an inner rod 9 is slidably connected to the inner center of the outer cylinder 1, and a plurality of arc covers 2 are rotatably connected to the bottom end of the outer cylinder 1 through a hinge, and an arc ring 3 is fixedly connected to the bottom end of the arc cover 2, and an operation window 4 is provided on the inner side of the arc ring 3, and a plurality of arc covers 2 and arc ring 3 can be spliced ​​inwardly and moved closer, and a plurality of arc covers 2 can be expanded outwardly, and a torsion spring 23 is fixedly connected between the top end of the arc cover 2 and the bottom end of the outer cylinder 1, and the torsion spring 23 provides elastic force for the arc cover 2 to expand outwardly;

[0050] After the arc covers 2 and the arc rings 3 are pressed down and brought close to the surface of the raw meat 13, a bulge 16 can be generated in the middle of the pressed area of ​​the raw meat 13, and the outer cutting knife 12 is operated through the operating window 4 to cut the bulge 16;

[0051] The bottom end of the inner rod 9 is connected with an inner cutting knife 15 , which can be tilted and vertical. After the protrusion 16 is peeled off, the raw meat 13 can be quickly sampled through the inner cutting knife 15 .

[0052] The pretreatment device in the present invention is flexible and compact, easy to use and can achieve a good pollution-free sampling effect. Under the above settings, before the present invention is used, the device is disinfected and cleaned before use, and the raw meat 13 is rinsed with physiological saline. When in use, first, a plurality of arc covers 2 and arc rings 3 are in an outwardly expanded state, and then a plurality of arc covers 2 and arc rings 3 are placed on the raw meat 13, and the plurality of arc covers 2 and arc rings 3 always maintain downward pressure on the raw meat 13, and then, the plurality of arc covers 2 and arc rings 3 are gradually spliced ​​inwardly and brought closer. In the process of splicing and bringing closer, the raw meat 13 under the plurality of arc covers 2 and arc rings 3 will be squeezed, so that the raw meat 13 will have a bulge 16 in the middle position of the downward pressure area and be tightened. The tightened raw meat is easier to cut, and then the outer cutting knife 12 The protrusion 16 is cut by operating the operating window 4, and finally the surface of the raw meat sample is cut. This cutting method can make the incision tight and neat, and avoids the problem that the manual removal method of scissors in the prior art is not convenient for fixing, which will make the cutting surface uneven during the cutting process, and easily cause the problem of incomplete removal of the surface of the raw meat sample. At the same time, because the arc cover 2 and the arc ring 3 are spliced ​​close together, a short-term relatively sealed environment is formed at the cutting position, ensuring a pollution-free environment for sampling. The set inner cutting knife 15 starts to press down to cut for sampling, and also realizes rapid and continuous sampling, avoiding the raw meat sample after removing the surface from being exposed to the air for a long time. While being convenient and fast, it minimizes pollution and improves the accuracy of identification.

[0053] After the arc cover 2 and the arc ring 3 are spliced ​​together, the bottom end of the arc ring 3 is inclined inwards.

[0054] In the present invention, after the arc cover 2 and the arc ring 3 are spliced ​​and brought close together, the bottom end of the arc ring 3 will be inclined inwards. This setting can increase the sensitivity of the protrusion 16 and make the protrusion more obvious.

[0055] Specifically, a pressure ring 8 is slidably connected to the outer side of the outer cylinder 1, and the pressure ring 8 is pressed downward to bring a plurality of unfolded arc covers 2 and arc rings 3 closer together.

[0056] Specifically, a thread is provided on the upper side of the outer cylinder 1, and a swivel 5 is spirally connected to the upper side of the outer cylinder 1. The bottom end of the swivel 5 is rotatably connected to a connecting ring 6 for rotation compensation. The bottom end of the connecting ring 6 is fixedly connected to a connecting rod 7. The bottom end of the connecting rod 7 is fixedly connected to the top end of the pressure ring 8 to realize synchronous up and down movement. The lifting and lowering movement of the pressure ring 8 is realized by the rotation of the swivel 5.

[0057] Under the above settings, in the present invention, the arc hoods 2 and arc rings 3 are expanded and brought together in the following manner: because a torsion spring 23 is fixedly connected between the top end of the arc hood 2 and the bottom end of the outer tube 1, the torsion spring 23 provides an elastic force for the arc hood 2 to expand outwards, and when the pressure ring 8 is not in contact with the arc hood 2, the arc hood 2 can be automatically expanded under the action of the torsion spring 23;

[0058] When the swivel 5 rotates, the swivel 5 can move downward on the outer cylinder 1, and the swivel 5 drives the pressure ring 8 to move downward through the swivel 5 and the connecting rod 7. After the pressure ring 8 moves downward and contacts the arc cover 2, the arc cover 2 starts the polarity approaching operation, and finally the protrusion 16 appears and plays the role of closing the sampling space.

[0059] Example 2: This example is a further development of Example 1. Figure 1-Figure 10 The same parts as those in Example 1 are not described in detail in this embodiment. The difference lies in that the top of the inner rod 9 is fixedly connected to a turntable for easy rotation, the bottom of the inner rod 9 is fixedly connected to a chassis 18, the inner side of the outer edge of the chassis 18 is rotatably connected to a rotating ball 21, the bottom end of the rotating ball 21 is fixedly connected to the top of the inner cutting knife 15, and the top of the rotating ball 21 is fixedly connected to a connecting rod 20. The angle of the inner cutting knife 15 can be changed by changing the inclination angle of the connecting rod 20.

[0060] Under the above setting, after the protrusion 16 is cut, the operator controls the inner rod 9 to descend, and the inner rod 9 drives the inner cutting knife 15 to descend and penetrate into the inner side of the raw meat 13 with the skin removed, so that the inner rod 9 rotates, drives the inner cutting knife 15 to rotate, and peels off the inside of the raw meat surrounded by multiple inner cutting knives 15, and then, the connecting rod 20 drives the inner cutting knife 15 to tilt inward. During the tilting process, the inner cutting knife 15 is still rotated by the inner rod 9, and the inner cutting knife 15 continuously peels off the raw meat to be sampled. When the bottom ends of multiple inner cutting knives 15 are in contact, the peeling is completed, and the inner rod 9 and its entire device are moved upward to complete the sampling of uncontaminated samples inside the raw meat.

[0061] Specifically, the number of the rotating balls 21 and the inner cutting knives 15 is at least two and they are evenly distributed on the chassis 18 .

[0062] Under the above arrangement, the number of the inner cutting knives 15 in the present invention is at least 2. This arrangement enables the multiple inner cutting knives 15 to clamp the sampled raw meat, thereby facilitating rapid completion of sampling.

[0063] Specifically, the outer side of the inner rod 9 is slidably connected with a cone cylinder 11, the bottom end of the cone cylinder 11 has a cone surface, the outer side of the bottom end of the cone cylinder 11 is provided with a slide groove 19 for limiting, the top end of the connecting rod 20 is slidably connected with the inner side of the slide groove 19, and the inner cutting knife 15 is tilted inwardly by the descent of the cone cylinder 11.

[0064] Under the above arrangement, the connecting rod 20 drives the inner cutting knife 15 to tilt in the following manner: when the cone 11 descends, the cone surface forces the connecting rod 20 to tilt outwards, and after the connecting rod 20 tilts outwards, the inner cutting knife 15 tilts inwards under the action of the rotating ball 21;

[0065] Specifically, a tension spring 22 is fixedly connected between the connecting rod 20 and the top end of the chassis 18 . After the cone 11 rises, the inner cutting knife 15 can be reset under the action of the tension spring 22 .

[0066] Under the above arrangement, after sampling is completed, the cone 11 moves upward, and the connecting rod 20 rotates toward the inner rod 9 under the action of the tension spring 22. At this time, the multiple inner cutting knives 15 are opened to realize the feeding of the sampled raw meat;

[0067] Specifically, the outer side of the inner rod 9 is fixedly connected to the motor 10, the main shaft end of the motor 10 is fixedly connected to the screw 17, the outer side of the screw 17 is spirally connected to the inner side of the cone 11, and the upward or downward movement of the cone 11 is achieved by the rotation of the motor 10.

[0068] Under the above arrangement, the cone 11 is lifted and lowered in the following manner: the motor 10 rotates, and the motor 10 drives the screw 17 to rotate. Since the screw 17 is spirally connected to the inner side of the cone 11, when the screw 17 rotates, the cone 11 can move upward or downward.

[0069] Specifically, the outer side of the inner rod 9 is also fixedly connected to a limit rod 14, and the outer side of the limit rod 14 is slidably connected to the inner side of the cone 11, so as to increase the stability of the cone 11 when it is lifted or lowered.
