[0027] Specifically, the workbench 1 provides support and protection for the entire device, and the support column 2 provides support for the workbench 1. When the metal detector body 21 does not detect the quick-frozen food containing metal objects, the quick-frozen food enters the discharge box 3 through the electric conveyor belt 5. After the metal detector body 21 detects the quick-frozen food containing metal objects, the metal detector body 21 will send out a warning indicator light. After receiving the indicator light instruction, the electric push rod 11 on the vertical plate 10 will push the push plate 8 away from the electric conveyor belt 5 and into the storage box 4. There is an iron-absorbing filter 22 in the storage box 4 that can absorb metal objects, and then the quick-frozen food without metal objects enters the storage box 4 through the holes in the iron-absorbing filter 22.

[0029] Specifically, after the quick-frozen food is placed on the electric conveyor belt 5, the hydraulic cylinder 7 is first used to adjust the height of the device on the support frame 9. When the height adjustment is completed, the first motor 12 is turned on to drive the first threaded rod 13 on one side to rotate, and the first threaded rod 13 on the other side will rotate together due to the action of the transmission belt, so that the first sliders 14 on the two first threaded rods 13 slide together, and the two first sliders 14 drive the first connecting rod 18 to move, and the first connecting rod 18 drives the support seat 20 and the metal detector body 21 on the support seat 20 to move. Similarly, the second motor 15 is turned on to drive the second threaded rod 16 on one side to rotate, and the second threaded rod 16 on the other side will rotate together due to the action of the transmission belt, so that the second sliders 17 on the two second threaded rods 16 slide together, and the two The second slider 17 drives the second connecting rod 19 to move, and the second connecting rod 19 drives the support seat 20 and the metal detector body 21 on the support seat 20 to move. By adjusting the hydraulic cylinder 7, the first motor 12 and the second motor 15, the metal detector body 21 can be moved to any position to adjust the quick-frozen food, thereby improving work efficiency and the practicality of the device. There is an electric control button on the workbench 1, which can electrically control the first motor 12, the second motor 15, the electric push rod 11 and the electric conveyor belt 5. The two first threaded rods 13 are fixed to the front and rear of the support frame 9 through four larger rectangular blocks, and the two second threaded rods 16 are fixed to the left and right of the support frame 9 through four smaller rectangular blocks. There is an indicator light on the metal detector body 21. When quick-frozen food containing metal objects is detected, the indicator light will light up.

The limit rod 25 and the support rod 26 are both close to the outer wall of the storage box 4, which has a good limiting effect on the magnetic filter 22.

[0032] Working principle: After the quick-frozen food is placed on the electric conveyor belt 5, the hydraulic cylinder 7 is first used to adjust the height of the device on the support frame 9. When the height adjustment is completed, the first motor 12 is turned on to drive the first threaded rod 13 on one side to rotate, and the first threaded rod 13 on the other side will rotate together due to the action of the transmission belt, thereby causing the first sliders 14 on the two first threaded rods 13 to slide together, and the two first sliders 14 drive the first connecting rod 18 to move, and the first connecting rod 18 drives the support seat 20 and the metal detector body 21 on the support seat 20 to move. Similarly, the second motor 15 is turned on to drive the second threaded rod 16 on one side to rotate, and the second threaded rod 16 on the other side will rotate together due to the action of the transmission belt, thereby causing the second sliders 17 on the two second threaded rods 16 to slide together, and the two second sliders 17 drive the second connecting rod 19 to move, and the second connecting rod 19 drives the support seat 20 and the metal detector body 21 on the support seat 20 to move. By adjusting the hydraulic cylinder 7, the first motor 12 and the second motor 15, the metal detector body 21 can be moved to any position to adjust the quick-frozen food. The metal detector body 21 detects the quick-frozen food containing metal objects, and the quick-frozen food enters the discharge box 3 through the electric conveyor belt 5. After the metal detector body 21 detects the quick-frozen food containing metal objects, the electric push rod 11 on the vertical plate 10 will push the push plate 8 away from the electric conveyor belt 5 and enter the storage box 4. There is an iron-absorbing filter 22 in the storage box 4 that can absorb metal objects, and then the quick-frozen food without metal objects enters the storage box 4 from the holes in the iron-absorbing filter 22. At 22, it is pulled out of the storage box 4 through the pull rod 23, and then the iron-absorbing filter 22 is pushed into the storage box 4 again, and the support rod 26 is pulled open to allow the limit rod 25 on the upper limit block 24 to pass through the pull rod 23 and enter the half-hole groove of the lower limit block 24 to fix the iron-absorbing filter 22 to prevent the iron-absorbing filter 22 from shifting due to the falling of the quick-frozen food. In this way, the device can automatically remove metal objects detected on the quick-frozen food and recycle the quick-frozen food after the metal objects are removed, thereby ensuring food safety, saving staff time and improving work efficiency.
