Description

Technical Field

[0001] This invention relates to the field of color sorting technology, and more particularly to a pickled vegetable color sorter. Background Technology

[0002] In the large-scale production of pickled vegetables, color sorting is a crucial step in ensuring product quality uniformity. High-quality pickled vegetables must have a uniform color, without obvious discolored spots or mold marks. Color sorting removes pickled vegetables with abnormal colors or defects, ensuring that the final product meets quality standards. For a long time, due to the irregular shape, high surface stickiness, and significant individual differences of pickled vegetables, the industry has mostly used manual color sorting. This involves workers visually identifying and sorting out substandard products next to the conveyor belt. This method is still relatively common in small workshops and some medium-sized enterprises. However, manual color sorting has many insurmountable problems. On the one hand, manual sorting is inefficient and cannot meet the efficiency requirements of large-scale production. On the other hand, manual identification is easily affected by subjective factors. Workers' visual fatigue, experience differences, and emotional fluctuations can lead to inconsistent judgment standards, resulting in missed or false detections, especially for defective products with subtle color differences, where the identification accuracy is often low. In addition, manual handling of pickled vegetables also poses food safety risks, increasing the risk of microbial contamination. Furthermore, long-term repetitive work can also harm workers' health, which is inconsistent with the trend of automation and standardization in modern food production. Therefore, a pickled vegetable color sorting machine has been developed. Summary of the Invention

[0014] Compared with the prior art, the present invention provides a pickled vegetable color sorter, which has the following beneficial effects: 1. This pickled vegetable color sorting machine improves color sorting accuracy by relying on a multi-dimensional adjustment and high-definition detection system. The second motor of the height adjustment mechanism drives the first threaded screw to make the first slider move up and down the lifting plate. The third motor of the longitudinal adjustment mechanism drives the second threaded screw to make the moving block move along the transverse groove.

[0015] 2. This pickled vegetable color sorter ensures feeding stability through a multi-stage pretreatment mechanism. In the rotating distribution mechanism, the first motor drives the transmission device to rotate the rotating roller in the opposite direction. The staggered feeding teeth evenly disperse the pickled vegetables falling from the feeding channel, preventing them from piling up. The rubber balls of the screening mechanism rotate with the rotating roller and impact the screen plate. Combined with the elasticity of the first spring, the screen plate vibrates at high frequency, allowing the pickled vegetables to pass through the screen holes one by one. The first electric push rod of the limiting and correction mechanism pushes the limiting plate. Combined with the vibration of the vibrating motor and the buffer of the second spring, the pickled vegetables are pushed to the middle of the conveyor belt, ensuring that the spacing between the pickled vegetables is uniform and the position is stable during subsequent testing.

[0016] 3. This pickled vegetable color sorter improves production efficiency and hygiene through automated sorting and a clean design. After receiving the detection signal, the control module links the second electric push rod to push the second push rod and the shovel plate. With the help of the high-pressure air pump, the airflow ejected through the air guide hose and the jet pipe efficiently pushes the unqualified pickled vegetables into the discharge trough, while qualified products are output along the sorting channel. The entire process requires no manual contact, reducing the risk of microbial contamination. Moreover, all contact parts of the equipment are made of food-grade materials, and the silicone material of the feeding teeth avoids damage to the pickled vegetables, meeting the hygiene standards of food production. At the same time, continuous automated operation greatly improves sorting efficiency and is suitable for large-scale pickled vegetable processing needs. Attached Figure Description

With automated sorting and clean design, production efficiency and hygiene are improved. After receiving the detection signal, the control module links the second electric push rod 12 to push the second push rod 51 and the shovel plate 52. With the airflow ejected by the high-pressure air pump 7 through the air guide hose 50 and the air jet pipe 53, the unqualified pickled vegetables are efficiently pushed into the discharge trough 49. Qualified products are output along the sorting channel 9. No manual contact is required throughout the process, reducing the risk of microbial contamination. Moreover, all contact parts of the equipment are made of food-grade materials, and the silicone material of the feeding teeth 17 avoids damage to the pickled vegetables, meeting the hygiene standards of food production. At the same time, continuous automated operation greatly improves sorting efficiency and is suitable for large-scale pickled vegetable processing needs.

[0022] In use, the pickled vegetables enter the feeding box 4 through the feeding channel 13. The first motor 22 drives the rotating rollers 16 at both ends to rotate in opposite directions through the transmission device 23. The staggered feeding teeth 17 evenly distribute the pickled vegetables to the lower screen plate 18. When the rotating rollers 16 rotate, they drive the rubber balls 14 to rotate synchronously through the rotating rod 15. The rubber balls 14 continuously hit the screen plate 18, and the elasticity of the first spring 19 causes the screen plate 18 to vibrate. The pickled vegetables fall through the screen holes 21 onto the hollow conveyor belt 3. The first electric push rod 10 pushes the first push rod 24, the connecting plate 25 and the limiting plate 27. With the buffering of the vibration motor 28 and the second spring 26, the pickled vegetables are pushed to the middle of the conveyor belt 3 and kept at a uniform spacing. Pickled vegetables enter the inspection area along conveyor belt 3. The second motor 35 drives the first threaded screw 37 to make the first slider 36 move the lifting plate 6 to adjust its height. The third motor 42 drives the second threaded screw 46 to make the second slider 48 move the moving block 44 along the transverse groove 45. The fourth motor 43 drives the rotating shaft 41 and the frame 40 to rotate, adjusting the shooting angle and position of the high-resolution industrial camera 39. The multispectral light source 32 and infrared light source 33 on the lamp holder 31 illuminate the pickled vegetables. The white background plate 29 provides a non-reflective background. The high-resolution industrial camera 39 captures images and transmits them to the data analysis module of the control box 11. After the data analysis module identifies pickled vegetables with discoloration or defects, the control module sends a signal to the second electric push rod 12 and the high-pressure air pump 7 at the corresponding positions. The second electric push rod 12 pushes the second push rod 51 and the shovel plate 52 closer to the pickled vegetables. At the same time, the high-pressure air pump 7 supplies air to the shovel plate 52 through the air guide hose 50. The airflow sprayed through the jet pipe 53 helps to push the unqualified pickled vegetables into the discharge trough 49, while the qualified pickled vegetables continue to move with the conveyor belt 3 and are finally output through the sorting channel 9 to complete the color sorting operation.
