[0014] A method for using a crushing device for solid food detection comprises the following steps:

[0015] S1: Put the solid food into the crushing cup, and then put the crushing cup into a feeding trough arranged opposite to the weight sensor, and drive the feeding plate to rotate 90 degrees by the second stepper motor, so that the feeding plate can cooperate with the material-moving spring to move the crushing cup to the arc-shaped limit plate when rotating;

[0018] S4: After the crushing cup is removed from the weight sensor, the telescopic end of the electric telescopic rod drives the push block to reset, and at the same time, the second stepper motor continues to drive the feeding plate to rotate 90 degrees, so that the crushing blade involved in the crushing operation moves to the top of the clearance groove, and at the same time, the guide rod is pushed downward by the second arc-shaped guide boss until the crushing blade passes through the clearance groove and is inserted into the fan-shaped cover, so that the flushing nozzle installed in the fan-shaped cover sprays cleaning liquid to first flush the crushing blade and the surface of the rotating rod, and then the hot air blower air-dries the crushing blade;

[0019] S5: After the crushing blades are cleaned, the second stepper motor continues to drive the feeding plate to rotate 90 degrees to complete the crushing and cleaning operations of one group of crushing blades.

[0020] The beneficial effects of the present invention are:

[0021] 1. By setting four sets of crushing blades to alternately perform crushing and cleaning operations under the rotation of the feeding plate, it can realize continuous crushing of various solid foods and improve the crushing efficiency of solid foods;

[0022] 2. After the solid food is crushed, the second stepper motor continues to drive the feed plate to rotate 90 degrees, so that the crushing cup moves to the weight sensor. At the same time, the corresponding hemispherical top cap is removed from the bottom of the first arc-shaped guide boss, so that the guide rod can drive the rotating rod and the crushing blade to move upward out of the crushing cup under the elastic force of the reset spring. At this time, the pressure sensor installed at the bottom of the first arc-shaped guide boss will stop the first stepper motor, so that the crushing blade stops rotating, avoiding the operator from touching the rotating crushing blade when picking up the crushing cup and causing the risk of scratches.

[0037] In this embodiment, the lifting mechanism includes two support plates 13 symmetrically fixedly installed on the upper surface of the support platform 2, a support ring 14 is fixedly installed between the top ends of the two support plates 13, and the upper surface of the support ring 14 is respectively fixedly installed with a first arc-shaped guide boss 15 and a second arc-shaped guide boss 16, the first arc-shaped guide boss 15 and the second arc-shaped guide boss 16 are relatively arranged, and the second arc-shaped guide boss 16 is arranged directly above the give way groove 17, the first arc-shaped guide boss 15 and the second arc-shaped guide boss 16 have inclined surface structures on opposite sides, and the length of the second arc-shaped guide boss 16 is longer than the length of the first arc-shaped guide boss 15, a hemispherical top cap 11 is fixedly installed on the top end of the guide rod 6, and a reset assembly is installed on the outer surface of the guide rod 6, and the bottom ends of the first arc-shaped guide boss 15 and the second arc-shaped guide boss 16 are embedded with pressure sensors 21, and the reset assembly includes a reset spring 12 sleeved on the outer surface of the guide rod 6, and the reset spring 12 is arranged between the hemispherical top cap 11 and the top end of the L-shaped plate 5.

[0038] When the feeding tray 3 rotates, the corresponding guide rod 6 and the rectangular mounting frame 7 will be driven to move as a whole through the L-shaped plate 5. When the hemispherical top cap 11 installed at the top of the guide rod 6 abuts against the hypotenuse of the first arc-shaped guide boss 15, the hypotenuse of the first arc-shaped guide boss 15 will squeeze the guide rod 6 as a whole downward through the hemispherical top cap 11, so that the rotating rod 9 and the crushing blade 10 can be inserted into the crushing cup. When the hemispherical top cap 11 abuts against the pressure sensor 21 installed at the bottom end of the first arc-shaped guide boss 15, the first stepper motor 8 is started, so that the first stepper motor 8 can drive the rotating rod 9 to rotate, so that the crushing blade 10 installed on the outer periphery of the rotating rod 9 can crush the solid food in the crushing cup, so that the crushed solid food can be extracted and tested later.

[0039] After the solid food is crushed, the second stepper motor 22 continues to drive the feeding plate 3 to rotate 90 degrees, so that the crushing cup moves to the weight sensor 23. At the same time, the corresponding hemispherical top cap 11 moves away from the bottom of the first arc-shaped guide boss 15, so that the guide rod 6 can drive the rotating rod 9 and the crushing blade 10 to move upward out of the crushing cup under the elastic force of the return spring 12.

[0040] In this embodiment, a pushing mechanism is installed inside the feed tray 3, and the pushing mechanism includes a mounting groove 29 opened on the feed tray 3 near the feed trough 4, an electric telescopic rod 25 is fixedly installed on the inner wall of the mounting groove 29, and a pushing block 26 is fixedly installed on the telescopic end of the electric telescopic rod 25.

[0041] When the weight sensor 23 detects the crushing cup, the telescopic end of the corresponding electric telescopic rod 25 installed inside the feeding tray 3 will push the push block 26 to move outward, so that the push block 26 pushes the crushing cup outward from the feeding trough 4, so that the crushing cup containing the crushed solid food can be taken out for subsequent detection operations.

[0042] In this embodiment, a water collecting box 28 is placed on the upper surface of the bottom plate 1 just below the give way groove 17. When in use, the sewage used to clean the crushing blade 10 will fall into the water collecting box 28 for collection; a material-push-away spring piece 27 is fixedly installed on the outer surface of the feed tray 3 near the feed groove 4, and the material-push-away spring piece 27 can assist the feed tray 3 in pushing the crushing cup to move.

[0043] A method for using a crushing device for solid food detection comprises the following steps:

[0044] S1: Put the solid food into the crushing cup, and then put the crushing cup into a feeding trough 4 arranged opposite to the weight sensor 23, and drive the feeding plate 3 to rotate 90 degrees by the second stepping motor 22, so that the feeding plate 3 can cooperate with the material-moving spring piece 27 to move the crushing cup to the arc-shaped limit plate 24 when rotating;

[0045] S2: When the feeding tray 3 rotates, the corresponding guide rod 6 and the rectangular mounting frame 7 are driven to move as a whole through the L-shaped plate 5. When the hemispherical top cap 11 installed at the top of the guide rod 6 abuts against the hypotenuse of the first arc-shaped guide boss 15, the hypotenuse of the first arc-shaped guide boss 15 will press the guide rod 6 as a whole downward through the hemispherical top cap 11, so that the rotating rod 9 and the crushing blade 10 can be inserted into the crushing cup. When the hemispherical top cap 11 abuts against the pressure sensor 21 installed at the bottom end of the first arc-shaped guide boss 15, the first stepper motor 8 is started, so that the first stepper motor 8 can drive the rotating rod 9 to rotate, so that the crushing blade 10 installed on the outer periphery of the rotating rod 9 can crush the solid food in the crushing cup;

[0046] S3: After the solid food is crushed, the second stepper motor 22 continues to drive the feeding tray 3 to rotate 90 degrees, so that the crushing cup moves to the weight sensor 23. At the same time, the corresponding hemispherical top cap 11 is removed from the bottom of the first arc-shaped guide boss 15, so that the guide rod 6 can drive the rotating rod 9 and the crushing blade 10 to move upward out of the crushing cup under the elastic force of the return spring 12. When the weight sensor 23 detects the crushing cup, the telescopic end of the corresponding electric telescopic rod 25 installed inside the feeding tray 3 will push the push block 26 to move outward, so that the push block 26 pushes the crushing cup outward from the feeding trough 4, and the crushing cup containing the crushed solid food is taken out;

[0047] S4: After the crushing cup is removed from the weight sensor 23, the telescopic end of the electric telescopic rod 25 drives the push block 26 to reset, and at the same time, the second stepper motor 22 continues to drive the feeding plate 3 to rotate 90 degrees, so that the crushing blade 10 involved in the crushing operation moves to the top of the make way groove 17, and at the same time, the guide rod 6 is pushed downward by the second arc-shaped guide boss 16 until the crushing blade 10 passes through the make way groove 17 and is inserted into the fan-shaped cover 18, so that the flushing nozzle 19 installed in the fan-shaped cover 18 sprays the cleaning liquid to first flush the surface of the crushing blade 10 and the rotating rod 9, and then the hot air blower 20 air-dries the crushing blade 10;

[0048] S5: After the crushing blades 10 are cleaned, the second stepper motor 22 continues to drive the feeding tray 3 to rotate 90° to complete the crushing and cleaning operations of one group of crushing blades 10 .

[0049] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when in use, solid food is placed in the crushing cup, and then the crushing cup is placed in a feeding trough 4 arranged opposite to the weight sensor 23, and the feeding disc 3 is driven by the second stepping motor 22 to rotate 90°, so that when the feeding disc 3 rotates, it can cooperate with the material-shifting spring piece 27 to shift the crushing cup to the arc-shaped limiting plate 24, so that the arc-shaped limiting plate 24 and the feeding trough 4 can limit the crushing cup, thereby preventing the crushing cup from moving during the solid food crushing operation, thereby affecting the crushing effect;

[0050] When the feeding tray 3 rotates, the corresponding guide rod 6 and the rectangular mounting frame 7 will be driven to move as a whole through the L-shaped plate 5. When the hemispherical top cap 11 installed at the top of the guide rod 6 abuts against the hypotenuse of the first arc-shaped guide boss 15, the hypotenuse of the first arc-shaped guide boss 15 will press the guide rod 6 as a whole downward through the hemispherical top cap 11, so that the rotating rod 9 and the crushing blade 10 can be inserted into the crushing cup. When the hemispherical top cap 11 abuts against the pressure sensor 21 installed at the bottom end of the first arc-shaped guide boss 15, the first stepper motor 8 is started, so that the first stepper motor 8 can drive the rotating rod 9 to rotate, so that the crushing blade 10 installed on the outer periphery of the rotating rod 9 can crush the solid food in the crushing cup, so that the crushed solid food can be extracted and tested later.

[0051] After the solid food is crushed, the second stepper motor 22 continues to drive the feeding tray 3 to rotate 90°, so that the crushing cup moves to the weight sensor 23. At the same time, the corresponding hemispherical top cap 11 is removed from the bottom of the first arc-shaped guide boss 15, so that the guide rod 6 can drive the rotating rod 9 and the crushing blade 10 to move upward out of the crushing cup under the elastic force of the reset spring 12 (at this time, the pressure sensor 21 installed at the bottom of the first arc-shaped guide boss 15 will stop the first stepper motor 8, so that the crushing blade 10 stops rotating, to avoid the operator from hitting the rotating crushing blade 10 when taking the crushing cup and causing the risk of scratches). When the weight sensor 23 detects the crushing cup, the telescopic end of the corresponding electric telescopic rod 25 installed inside the feeding tray 3 will push the push block 26 to move outward, so that the push block 26 pushes the crushing cup outward from the feeding trough 4, so that the crushing cup containing the crushed solid food can be taken for subsequent detection operations;

[0052] After the crushing cup is removed from the weight sensor 23, the telescopic end of the electric telescopic rod 25 drives the push block 26 to reset, and at the same time, the second stepper motor 22 continues to drive the feeding plate 3 to rotate 90 degrees, so that the crushing blade 10 involved in the crushing operation moves to the upper side of the clearance groove 17, and at the same time, the guide rod 6 is pushed downward by the second arc-shaped guide boss 16 until the crushing blade 10 passes through the clearance groove 17 and is inserted into the fan-shaped cover 18, so that the flushing nozzle 19 installed in the fan-shaped cover 18 sprays a cleaning liquid to first flush the surface of the crushing blade 10 and the rotating rod 9, and then the hot air blower 20 air-dries the crushing blade 10 so that the crushing blade 10 can crush the solid food next time; by arranging four groups of crushing blades 10 to alternately perform crushing and cleaning operations, continuous crushing operations for multiple solid foods can be achieved, thereby improving the crushing efficiency of solid foods;

[0053] When the hemispherical top cap 11 abuts against the pressure sensor 21 installed at the bottom of the second arc-shaped guide boss 16, the first stepper motor 8 continues to drive the rotating rod 9 to rotate, so that the crushing blade 10 can rotate accordingly, so that the flushing nozzle 19 and the hot air blower 20 can fully clean the crushing blade 10;

[0054] After the crushing blades 10 are cleaned, the second stepper motor 22 continues to drive the feeding tray 3 to rotate 90 degrees to complete the crushing operation and cleaning operation of one group of crushing blades 10 .

[0055] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

A second stepper motor (22) is fixedly mounted on the lower surface of the support platform (2), and the output end of the second stepper motor (22) passes through the upper surface of the support platform (2) and is fixedly mounted to the rotation center of the feeding tray (3).

8. The solid food testing crushing device according to claim 1, characterized in that: A water collecting box (28) is placed on the upper surface of the bottom plate (1) directly below the clearance groove (17), and a material-discharging spring piece (27) is fixedly mounted on the outer surface of the feeding tray (3) close to the feeding groove (4).

9. A method for using a crushing device for solid food testing, characterized in that: The solid food crushing device according to any one of claims 1 to 8 comprises the following steps: S1: Put the solid food into the blending cup, and then put the blending cup into a feeding trough (4) arranged opposite to the weight sensor (23), and drive the feeding plate (3) to rotate 90 degrees by the second stepping motor (22), so that the feeding plate (3) can cooperate with the material shifting spring (27) to shift the blending cup to the arc-shaped limit plate (24) when rotating; S2: When the feeding plate (3) rotates, the corresponding guide rod (6) and the rectangular mounting frame (7) are driven to move as a whole through the L-shaped plate (5). When the hemispherical top cap (11) installed at the top of the guide rod (6) abuts against the hypotenuse of the first arc-shaped guide boss (15), the hypotenuse of the first arc-shaped guide boss (15) presses the guide rod (6) as a whole downward through the hemispherical top cap (11), so that the rotating rod (9) and the crushing blade (10) can be inserted into the crushing cup. When the hemispherical top cap (11) abuts against the pressure sensor (21) installed at the bottom end of the first arc-shaped guide boss (15), the first stepper motor (8) is started, so that the first stepper motor (8) can drive the rotating rod (9) to rotate, so that the crushing blade (10) installed on the outer periphery of the rotating rod (9) can crush the solid food in the crushing cup; S3: After the solid food is crushed, the second stepper motor (22) continues to drive the feeding plate (3) to rotate 90 degrees, so that the crushing cup moves to the weight sensor (23). At the same time, the corresponding hemispherical top cap (11) moves away from the bottom of the first arc-shaped guide boss (15), so that the guide rod (6) can drive the rotating rod (9) and the crushing blade (10) to move upward out of the crushing cup under the elastic force of the return spring (12). When the weight sensor (23) detects the crushing cup, the telescopic end of the corresponding electric telescopic rod (25) installed inside the feeding plate (3) will push the push block (26) to move outward, so that the push block (26) pushes the crushing cup out of the feeding trough (4), and the crushing cup containing the crushed solid food is taken out; S4: After the crushing cup is removed from the weight sensor (23), the telescopic end of the electric telescopic rod (25) drives the push block (26) to reset, and at the same time, the second stepping motor (22) continues to drive the feeding plate (3) to rotate 90 degrees, so that the crushing blade (10) involved in the crushing operation moves to the upper side of the clearance groove (17), and at the same time, the guide rod (6) is pushed downward by the second arc-shaped guide boss (16) until the crushing blade (10) passes through the clearance groove (17) and is inserted into the fan-shaped cover (18), so that the flushing nozzle (19) installed in the fan-shaped cover (18) sprays a cleaning liquid to first flush the surface of the crushing blade (10) and the rotating rod (9), and then the hot air blower (20) air-dries the crushing blade (10); S5: After the crushing blades (10) are cleaned, the second stepper motor (22) continues to drive the feeding plate (3) to rotate 90 degrees to complete the crushing operation and cleaning operation of one group of crushing blades (10).
