[0039] Working principle and advantages of the present invention: When the weighing device for solid food detection performs weight detection on solid food products, the working process is as follows:

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, the motor is started to work, so that the motor drives the turntable 7 to rotate through the rotating shaft 9, so that the turntable 7 drives the conveyor belt 8 to run, and the conveyor belt 8 is set to Figure 1 The machine runs counterclockwise, and the heights of the three detection baffles 20 on the cross support plate 10 increase from right to left in sequence under the adjustment of the screw 19. The heights of the detection baffles 20 can be adjusted by the screw 19 according to the weight range of the solid food products to be detected. This can be suitable for weight detection of solid food products of different weight specifications, improve practicality, and adjust the qualified weight range of the solid food products to be detected.

[0041] After adjusting the height of each detection baffle 20, the solid food products to be inspected are placed one by one on the tray 5 at the rightmost end of the horizontal section of the conveyor belt 8 using a robotic arm or manually. The conveyor belt 8 drives the tray 5 to move the solid food products to be inspected thereon to the left, and due to the effect of gravity, the solid food products to be inspected drive the support 11 to move downward through the tray 5. The greater the mass of the solid food products to be inspected, the greater the downward movement of the support 11. The downward movement of the support 11 compresses the spring 12, so that the spring 12 obtains an upward restoring force.

[0042] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the downward movement of the support platform 11 synchronously drives the slide bar 25 downward, so that the slide bar 25 synchronously drives the slide 16 downward, and then the slide 16 drives the rack 21 and the protruding rod 17 downward. When the solid food product to be detected is overweight, the protruding rod 17 moves downward by a large amplitude, so that in the process of moving left, it first contacts and buckles with the shortest detection stopper 20 at the right end of the cross brace 10, and the detection stopper 20 drives the rack 21 to move right on the slide 16 through the protruding rod 17, so that the rack 21 compresses the spring 23 through the vertical rod 12, so that the spring 23 obtains a restoring force, and the rightward movement of the rack 21 The gear 15 drives the rack 13 to move upward. While the rack 13 moves upward, the two connecting rods 1 28 apply a pulling force to the two connecting rods 3 39, so that the two connecting rods 3 39 are close to each other, so that the two connecting rods 3 39 drive the two ends of the lower end of the scissor rod group 29 to be close to each other, so that the two angles in the upper and lower directions of the scissor rod group 29 become smaller, and the length in the vertical direction increases, so that the two ends of the upper end of the scissor rod group 29 are close to each other, and the slide 31 is lifted up by the two connecting rods 2 30, so that the slide 31 pushes the pallet 5 to flip around the hinge shaft 32, so that the pallet 5 turns the overweight on it. The solid food products are unloaded onto the corresponding guide plates 33, so that the overweight solid food products are collected in the corresponding collection box 34 through the guide plates 33, and after the tray 5 unloads the solid food, it is no longer subjected to downward pressure, so that the support table 11 is moved up and reset under the restoring force of the spring 12, and then the support table 11 drives the slide 16, the rack 21 and the convex rod 17 to move up and reset through the slide bar 25. After the convex rod 17 is reset, it is separated from the detection stopper 20, so that the rack 21 is moved leftward and reset on the slide 16 under the restoring force of the spring 23, and at the same time, the rack 21 drives the gear 15 to move upward and reset. When the rack bar 13 moves downward, the two connecting rods 1 28 apply a thrust to the two connecting rods 3 39 at the same time, so that the two connecting rods 3 39 move away from each other, thereby making the two connecting rods 3 39 drive the two ends of the lower end of the scissor lever group 29 to move away from each other, thereby making the two angles of the scissor lever group 29 in the upper and lower directions larger, and reducing the length in the vertical direction, thereby making the two ends of the upper end of the scissor lever group 29 move away from each other, and driving the slide 31 downward through the two connecting rods 2 30, thereby making the slide 31 push the tray 5 to flip in the opposite direction around the hinge shaft 32, thereby making the tray 5 automatically reset after unloading the solid food product.

[0043] When the solid food product to be detected is too light, the downward movement of the protruding rod 17 is small. Therefore, during the left movement process, it first contacts and engages with the detection stop rod 20 which is the highest at the left end of the cross brace 10. As mentioned above, the detection stop rod 20 drives the unloading mechanism through the trigger mechanism to push the tray 5 to flip around the hinge shaft 32, thereby causing the tray 5 to unload the solid food product that is too light onto the corresponding guide plate 33, so that the solid food product that is too light is collected in the corresponding collection box 34 through the guide plate 33. After the tray 5 unloads the solid food, it is no longer subjected to the downward pressure. Therefore, under the action of the restoring force of the spring 12, the support platform 11 is moved up and reset, and then the support platform 11 drives the slide 16, the rack 21 and the protruding rod 17 to move up and reset through the slide bar 25. After the protruding rod 17 is reset, it is disengaged from the detection stop rod 20. Therefore, when the trigger mechanism is reset, the unloading mechanism is driven to drive the tray 5 to flip in the opposite direction around the hinge shaft 32, thereby causing the tray 5 to automatically reset after unloading the solid food product.

[0044] When the weight of the solid food product to be detected is within the qualified range, the protruding rod 17 moves downward by a moderate amplitude, so that in the process of moving to the left, it first contacts and engages with the detection stop rod 20 in the middle position on the cross brace 10, and as mentioned above, the detection stop rod 20 drives the unloading mechanism through the trigger mechanism to push the tray 5 to flip around the hinge shaft 32, so that the tray 5 can unload the solid food products that are too light on it to the corresponding guide plate 33, so that the qualified solid food products are collected in the corresponding collection box 34 through the guide plate 33, and after the tray 5 unloads the solid food, it is no longer subjected to the downward pressure, so that under the action of the restoring force of the spring 12, the support platform 11 moves up and resets, and then the support platform 11 drives the slide 16, the rack 21 and the protruding rod 17 to move up and reset through the slide bar 25. After the protruding rod 17 is reset, it disengages from the detection stop rod 20, so that when the trigger mechanism is reset, the unloading mechanism is driven to drive the tray 5 to flip in the opposite direction around the hinge shaft 32, so that the tray 5 automatically resets after unloading the solid food products.

[0045] In summary, the present application realizes weight detection of solid food products one by one, and at the same time, overweight products, qualified products, and underweight products are sorted and collected separately, so that products that do not meet the weight requirements are accurately and comprehensively selected. The whole process has a high degree of automation, which greatly improves work efficiency, and facilitates the comprehensive weight detection of solid food products, improves the qualified rate of products, and the circulating operation of the conveyor belt 8 makes the whole working process continuous, greatly improving work efficiency.
