[0001] The invention belongs to the technical field of meat detection and testing devices, and in particular relates to a multifunctional sample preparation device for meat detection and testing. Background Art

[0002] Meat quality testing is of great significance in the breeding industry. The preparation of meat samples for testing has a great impact on the test results. In the existing meat testing process, meat samples are mostly prepared manually, which has the characteristics of high labor intensity, low meat sample size accuracy, and easy to cause cuts to the experimenters. This leads to low utilization rate of meat samples and low test efficiency. At the same time, low sample preparation accuracy can easily lead to slow progress in improving breeding technology based on the test results.

[0003] Existing sample preparation devices for meat inspection and testing are mostly for the preparation of meat samples of specific sizes. For example, patent application number 202010109202.5 discloses a standard square meat sampling mold, which is a meat sampling device for food inspection and testing. The device is mainly a mold for the preparation of standard square meat samples of specific sizes. The invention can prepare standard square meat samples of different thickness specifications and has an automatic demolding function.

[0004] According to the objective evaluation method of meat quality in the agricultural industry standard NY / T2793-2015, the meat quality testing test standard has strict requirements on the preparation size of meat samples in meat testing tests, especially the detailed description of the longitudinal and transverse dimensions of meat samples for testing. It is of great significance to design a multifunctional meat testing sample preparation device according to the size requirements of meat samples in the test. Summary of the invention

[0005] In order to solve the above-mentioned problems existing in the prior art, the purpose of the present invention is to provide a multifunctional sample preparation device for meat detection and testing, which has vertical and horizontal cutting functions, and the vertical cutting direction can be adjusted so that the device can cut in three dimensions, which can meet the preparation of meat samples of various shapes and thicknesses, greatly reducing the labor intensity of sample preparation in meat detection, and at the same time improving the accuracy of sample preparation.

[0006] The technical solution adopted by the present invention is:

[0007] A multifunctional sample preparation device for meat detection and testing comprises a frame, a lifting drive mechanism is installed in the frame, the output end of the lifting drive mechanism is connected to a lower pressure plate, a tapered hole rotating shaft is installed on the lower pressure plate, the lower end of the tapered hole rotating shaft is connected to a rotating frame, a vertical tool guide rail is horizontally arranged on the rotating frame, a plurality of vertical tool assemblies are slidably arranged on the vertical tool guide rail, and a plurality of clamping mechanisms are connected to the vertical tool assembly; an angle adjustment mechanism is installed on the top of the frame, and the tapered hole rotating shaft engages with the angle adjustment mechanism after the lower pressure plate is raised; a transverse driving mechanism is also installed in the frame, the output end of the transverse driving mechanism is connected to a horizontal tool holder, a height adjustment member is vertically installed on the horizontal tool holder, and a horizontal tool assembly is connected to the height adjustment member.

[0008] Place the meat block to be sampled at a specific position in the rack, adjust the spacing of the vertical knife assembly according to the length and size of the meat sample, and fix it. The lifting drive mechanism drives the lower pressure plate to move downward, and the clamping mechanism on the vertical knife assembly first contacts the meat block, and automatically clamps it under the action of the clamping mechanism. As the lower pressure plate continues to move downward, the vertical knife assembly cuts the meat sample vertically (in the length direction).

[0009] The lower pressing plate is raised by the lifting drive mechanism, and the angle adjustment mechanism is engaged with the tapered hole shaft on the rotating frame. The spacing of the vertical knife assembly is adjusted again according to the width size requirements of the meat sample and fixed. The lifting drive mechanism drives the lower pressing plate to move downward, the pressing mechanism presses the meat block, and the vertical knife assembly cuts the meat sample vertically (in the width direction).

[0010] Next, the lifting drive mechanism drives the lower pressing plate to move upward so that the tapered hole axis engages with the angle adjustment mechanism again. According to the requirements of the meat sample in the thickness direction, the height of the horizontal tool assembly is adjusted by the height adjustment member. The lower pressing plate is moved downward by the lifting drive mechanism until the clamping mechanism contacts the meat block to complete the clamping of the meat block. Then, the horizontal tool assembly is driven by the transverse drive mechanism to complete the cutting of different meat sample thickness sizes (thickness direction). After the cutting is completed, the meat sample is taken out to complete the preparation operation of the meat sample with the length, width and thickness direction size requirements.

[0011] When the present invention cuts the meat sample in the length, width and thickness directions, the meat sample is positioned and pressed by a pressing mechanism, thereby avoiding the need to re-place the meat block, and the size of the meat sample is accurately controlled, thereby greatly improving the sample preparation efficiency.

[0012] The present invention can adjust the lateral position of the vertical knife assembly, the angle of the vertical knife assembly, and the height of the horizontal knife assembly, so that the meat sample after cutting meets the size requirements in different length, width and thickness directions, greatly reducing the repeated measurement and positioning of the meat sample during the sample preparation process, and improving the sample preparation efficiency and labor workload.

[0013] After the meat sample is cut in the length direction, the invention can adjust the direction of the vertical knife assembly through the angle adjustment mechanism so as to cut the meat sample in the width direction. The invention can complete the cutting in the length direction and the width direction only through the vertical knife assembly, which can simplify the system structure and the operation difficulty.

[0014] As a preferred solution of the present invention, a sample preparation platform is provided at the bottom of the frame, and a sample preparation plate for placing meat is provided on the sample preparation platform. When preparing samples of meat to be tested, the sample preparation plate is first taken out, the meat block is placed on the sample preparation plate, and then the sample preparation plate is placed on the sample preparation platform.

After the lower pressure plate is raised by the lifting drive mechanism, the tapered hole of the tapered hole shaft contacts and meshes with the tapered shaft. Since the cross-sectional shapes of the tapered hole shaft and the tapered shaft are both polygonal, when the handle is turned, the handle can drive the rotating frame and the vertical tool assembly on the rotating frame to rotate, so as to cut the width direction of the meat block after completing the length direction. In addition, when the lower pressure plate is lowered, the tapered hole shaft can be automatically separated from the tapered shaft.

[0016] As a preferred solution of the present invention, a rotating guide groove is provided on the top of the frame, a positioning spring pin is fixed on the handle, and the lower part of the positioning spring pin is slidably arranged in the rotating guide groove, and the shape of the rotating guide groove is a quarter arc groove centered on the tapered axis. The rotating guide groove is a quarter arc groove, so that the rotating guide groove can limit the positioning spring pin on the handle. When the handle is rotated to the extreme position on one side, the vertical tool assembly rotates to the length cutting direction; when the handle is rotated to the extreme position on the other side, the vertical tool assembly rotates to the width cutting direction.

The spring is sleeved on the pressure rod. In a natural state, the lower end of the pressure rod is lower than the lower end of the vertical tool assembly. When the lower pressure plate is lowered, the pressure rod first contacts the meat block under the action of the spring, so that the pressure rod can press the meat block to avoid the movement of the meat sample when cutting in the length direction, width direction and thickness direction respectively, thereby ensuring the accuracy of the meat sample cutting. When cutting in the length direction and width direction, the lower pressure plate is continued to be lowered, and the spring is compressed, so that the vertical tool assembly can contact the meat block and cut the meat block.

[0019] As a preferred solution of the present invention, the horizontal tool assembly includes a horizontal tool mounting plate, the horizontal tool mounting plate is connected to the height adjustment member, and a horizontal tool is mounted on the horizontal tool mounting plate.

When preparing samples of meat to be tested, the sample preparation plate 17 is first taken out, the meat block is placed on the sample preparation plate 17, and then the sample preparation plate 17 is placed on the sample preparation platform 16. After cutting is completed, the sample preparation plate 17 is taken out to take out the meat sample.

[0047] Specifically, Figure 5 and Figure 6As shown, a fixed plate 18 is fixed on the top of the frame 1, and the angle adjustment mechanism 6 includes a tapered shaft 61 connected to the fixed plate 18 through a bearing. After the lower pressing plate 2 is raised, the tapered hole of the tapered hole rotating shaft 21 is meshed with the tapered shaft 61, and a handle 62 is connected to the tapered shaft 61. The cross-sectional shapes of the tapered hole rotating shaft 21 and the tapered shaft 61 are both polygonal. After the lifting drive mechanism raises the lower pressing plate 2, the tapered hole of the tapered hole rotating shaft 21 contacts and meshes with the tapered shaft 61. Since the cross-sectional shapes of the tapered hole rotating shaft 21 and the tapered shaft 61 are both polygonal, when the handle 62 is rotated, the handle 62 can drive the rotating frame 3 and the vertical tool assembly 4 on the rotating frame 3 to rotate, so as to cut the width direction of the meat block after completing the length direction. In addition, when the lower pressing plate 2 is lowered, the tapered hole rotating shaft 21 can be automatically separated from the tapered shaft 61.

The spring 53 is sleeved on the pressure rod 52. In a natural state, the lower end of the pressure rod 52 is lower than the lower end of the vertical tool assembly 4. When the lower pressing plate 2 is lowered, the pressure rod 52 first contacts the meat block under the action of the spring 53, so that the pressure rod 52 can press the meat block tightly to avoid the meat sample from moving when cutting in the length direction, width direction and thickness direction respectively, thereby ensuring the accuracy of the meat sample cutting. When cutting in the length direction and width direction, the lower pressing plate 2 is continuously lowered, and the spring 53 is compressed, so that the vertical tool assembly 4 can contact the meat block and cut the meat block.

After the cutting is completed, the lower pressing plate 2 moves up under the control of the cutting device controller 9 and the lower pressing plate position sensor 22 so that the tapered hole shaft engages with the tapered shaft 61. Then rotate the handle 62 to drive the tapered shaft 61 to rotate, thereby driving the tapered hole shaft, the tapered hole shaft drives the rotating frame 3 to rotate, and the rotation of the rotating frame 3 drives the vertical knife holder 41 to rotate, completing the adjustment of the angle of the vertical tool 42. Then adjust the distance between the vertical knife holders 41 according to the width direction size requirements of the meat sample. Start the vertical automatic cutting button 92 again to complete the cutting of the width direction size of the meat sample in the vertical direction. After the cutting is completed, the lower pressing plate 2 moves upward under the control of the cutting device controller 9 and the lower pressing plate position sensor 22, so that the tapered hole axis is again engaged with the tapered axis 61. Then the sample preparation plate 17 is taken out, and the preparation operation of the meat sample with the required length and width dimensions is completed.

[0056] In some cases, it is also necessary to cut the meat in the thickness direction. After completing the cutting in the length and width directions, the lower pressing plate 2 is moved up under the control of the cutting device controller 9 and the lower pressing plate position sensor 22 so that the tapered hole axis is meshed with the tapered axis 61 again. According to the requirements of the meat sample in the thickness direction, the adjustment screw 71 is adjusted to complete the adjustment in the thickness direction.
