Description

Technical Field

[0001] The present invention relates to the technical field of color sorting equipment, and in particular to color sorting equipment for alkaline wet materials. Background Art

[0002] Color sorting equipment is a device that automatically sorts out different-colored particles in granular materials based on the differences in the optical properties of the materials. It is a high-tech product integrating light, machinery, electricity, gas, and magnetism, and is widely used in the quality inspection and grading fields of bulk materials or packaged industrial products and foods. It can effectively achieve the removal of foreign objects and grade classification, and is a key device for ensuring the safety and quality of agricultural products and increasing the added value of agricultural products.

[0003] When the color sorting equipment screens alkaline wet materials, the materials fall in a parabolic trajectory at the end of the conveyor belt, and some materials adhere to the conveyor belt, causing them to fall on the recognition end of the optical detection system. After long-term operation, the recognition end will be blocked by the materials, resulting in a decrease in the recognition accuracy.

[0004] The existing solution is to use an electric rail-driven scraper to continuously clean the recognition end face. However, when the scraper is cleaning, it will inevitably block a recognition area, resulting in the materials in this part of the area not being recognized and sorted, thus affecting the sorting quality.

Detailed implementation manners

[0034] The following uses specific specific examples to illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0035] The existing solution is to use an electric rail to drive a scraper to continuously clean the recognition end face. However, the scraper will inevitably block a recognition area during cleaning, resulting in the materials in this part of the area not being recognized and sorted, thus affecting the sorting quality.

[0036] To solve this problem, please refer to Figures 1-9 , a color sorting device for alkaline wet materials, comprising: a feeding device 1 for conveying materials;

[0037] a receiving hopper 2 for receiving the materials conveyed by the feeding device 1;

[0038] a jet sorter 3 for screening and separating the materials conveyed by the feeding device 1 during the process of falling into the receiving hopper 2;

[0039] An optical detection system 4 for identifying the material during the process of the material conveyed by the feeding device 1 falling into the receiving hopper 2, and sending the identification result to the jet sorter 3; and

[0040] A cleaning mechanism 5 for protecting the identification end of the optical detection system 4 from contamination and ensuring that the identification of the identification end of the optical detection system 4 is not affected

[0041] During use, the alkaline wet material is continuously fed by the feeding device 1. When the material reaches the end of the feeding device 1, it will continue to move forward due to inertia and fall in a parabolic shape. The optical detection system 4 identifies the falling material, and the identified structure is sent to the jet sorter 3. The jet sorter 3 screens the material according to the identification structure. The material that is not screened out falls into the receiving hopper 2 and is transported through collection. When the optical detection system 4 identifies the material, it cannot be too far away from the falling material, and it will inevitably be contaminated by the material during identification. The cleaning mechanism 5 protects and cleans the optical detection system 4 so that it can be unaffected when identifying the material.

[0042] In a specific implementation process, such as Figure 2 shown, the cleaning mechanism 5 includes a protection component 51, a cleaning component 52, a wiping component 53, a tensioning component 54, and a transmission component 55;

[0043] The protection component 51 is used to block foreign objects from falling on the identification end of the optical detection system 4. The transmission component 55 is used to drive the protection component 51 to rotate to realize the transfer of foreign objects falling on the protection component 51. The cleaning component 52 is used to clean the transferred foreign objects, and the wiping component 53 dries and cleans the protection component 51 after cleaning. The tensioning component 54 is used to adjust the tightness of the protection component 51

[0044] During use, the protection component 51 protects the optical detection system 4 from contamination, so that its identification end can not be contaminated. Contaminants will adhere to the protection component 51 during long-term shielding. The transmission component 55 drives the protection component 51 to transfer the contaminants. The cleaning component 52 flushes the removed contaminants and collects the flushing liquid and foreign objects for subsequent reprocessing. After flushing, the wiping component 53 wipes it dry and makes it rotate for recycling.

[0045] In a specific implementation process, such as Figures 3 to 6 shown, the protection component 51 at least includes: the protection component 51 at least includes: a support frame 511, a driving shaft 513, two driven shafts 514, and a film body 515;

[0046] Both ends of the support frame 511 are connected to a mounting plate 512. The driving shaft 513 is located between the two mounting plates 512 and is rotatably connected to the mounting plates 512. One end of the driving shaft 513 passes through the corresponding mounting plate 512. One of the driven shafts 514 is rotatably connected to the corresponding mounting plates 512 at both ends, and there is a tensioning assembly 54 between the other driven shaft 514 and the mounting plate 512. The two ends of the driven shaft 514 are respectively connected to the corresponding mounting plates 512 through the tensioning assembly 54. The driving shaft 513 and the two driven shafts 514 are arranged in parallel, and the geometric structure formed by the driving shaft 513 and the two driven shafts 514 tensions the membrane body 515. After the membrane body 515 is tensioned, a space for placing the optical detection system 4 is formed inside. The end of the driving shaft 513 extending out of the mounting plate 512 is in transmission connection with the transmission assembly 55;

[0047] A support plate 516 is fixed at the bottom between the two mounting plates 512. The support plate 516 is located inside the membrane body 515 to support its bottom, so that the inner surface of the membrane body 515 always slides and fits the bottom of the support plate 516.

[0048] When the protection assembly 51 is in use, the membrane body 515 is an alkali-resistant transparent film, so that it will not affect the recognition of the optical detection system 4 during use. The recognition end of the optical detection system 4 is protected by the membrane body 515. The membrane body 515 is driven to rotate continuously by the driving shaft 513 and the driven shafts 514, and the foreign matters attached to the outer surface of the membrane body 515 are moved upward, which is convenient for cleaning the foreign matters, so that the recognition end of the optical detection system 4 will not be affected when cleaning the foreign matters. The support plate 516 at the bottom of the mounting plate 512 provides a top supporting force for the wiping assembly 53 and the water hanging strip 528.

[0049] In the specific implementation process, as Figure 3 shown, the cleaning assembly 52 at least includes a water tank 521, a pumping assembly 524 and a controller 522;

[0050] A controller 522 is mounted on a pair of mounting plates 512. At the bottom of the controller 522, cleaning nozzles 523 for flushing foreign matters on the surface of the membrane body 515 are arranged in a row, and the controller 522 is used to control the opening or closing of the cleaning nozzles 523. The water tank 521 is communicated with the cleaning nozzles 523 through the pumping assembly 524. Above the water tank 521, there is a neutralization tank 525 for receiving the flushing waste liquid. A filter screen 526 is detachably arranged in the neutralization tank 525.

[0051] In use, after the film body 515 drives the foreign matter to move upward, the pumping assembly 524 pumps out the weak acid liquid in the water tank 521 and pumps it to the cleaning spray head 523. The cleaning spray head 523 is controlled by the controller 522 to discharge water simultaneously. The controller 522 is a prior art. After the pumped liquid reaches the moving pressure, the cleaning spray head 523 is simultaneously opened to discharge water simultaneously to clean the foreign matter on the outer surface of the film body 515.

[0052] In the specific implementation process, such as Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, the wiping assembly 53 at least includes a long strip box 531, a reciprocating rod 532, and a gear set 534. A reciprocating rod 532 is rotatably arranged in the long strip box 531. A reciprocating groove 533 is formed on the reciprocating rod 532. One end of the reciprocating rod 532 extending out of the long strip box 531 is in transmission connection with the output end of the gear set 534. A motor 535 in transmission connection with the input end of the gear set 534 is arranged on the support frame 511. A support rod 536 is slidably arranged on the long strip box 531. A slider 537 is slidably arranged in the reciprocating groove 533. The top of the slider 537 is rotatably connected to the bottom of one end of the support rod 536. A wiping cotton strip 538 is detachably arranged at the other end of the support rod 536. The top of the wiping cotton strip 538 is attached to the outer surface of the film body 515.

[0053] In use, after the film body 515 is rinsed with weak acid water, a part of the water stain remains on the outer surface of the film body 515. The motor 535 is started. The motor 535 drives the reciprocating rod 532 to rotate through the gear set 534. The reciprocating rod 532 drives the slider 537 through the reciprocating groove 533 on the surface to reciprocate in the long strip box 531. The slider 537 drives the wiping cotton strip 538 to reciprocate left and right through the support rod 536. The water stain on the outer surface of the film body 515 is wiped off through the movement of the wiping cotton strip 538, so that when the film body 515 rotates to the recognition side of the optical detection system 4, it will not block the recognition.

[0054] In the specific implementation process, such as Figure 9 As shown, the tensioning assembly 54 includes a fixing plate 541. The fixing plate 541 is fixed on the opposite side of the corresponding mounting plate 512. A threaded rod 542 is fixed on one side of the fixing plate 541. An elastic member 543 is arranged on one side of the fixing plate 541. Connecting blocks 544 are slidably arranged on the threaded rods 542. The connecting blocks 544 are respectively rotatably arranged at both ends of the driven shaft 514. The other end of the elastic member 543 is fixedly connected to the connecting block 544. Nuts 545 are respectively threaded on the ends of the threaded rods 542.

[0055] When the membrane body 515 is in use, it may be too tightly tensioned or too loose, both of which will affect the normal use of the protection component 51. When the membrane body 515 is too tightly tensioned, turn the nut 545. The nut 545 pushes the connecting block 544 to move towards the mounting plate 512 and squeezes the elastic member 543. The connecting block 544 drives a driven shaft 514 to move towards the driving shaft 513, reducing the pulling force on the membrane body 515 and the tension of the membrane body 515. When the membrane body 515 is too loose, turn the nut 545 in the reverse direction. The nut 545 moves towards the end of the threaded rod 542, and the elastic member 543 will push the connecting block 544 to move together with the nut 545. The connecting block 544 drives the driven shaft 514 away from the driving shaft 513, increasing the pulling force on the membrane body 515 to make it tensioned.

[0056] In the specific implementation process, such as Figure 6 and Figure 9 As shown, the transmission component 55 includes a driving wheel 551 and a driven wheel 552. The driving wheel 551 is arranged at one end of the reciprocating rod 532 away from the motor 535, and the driven wheel 552 is arranged at one end of the driving shaft 513 extending out of the mounting plate 512. A transmission belt 553 is sleeved on the driving wheel 551 and the driven wheel 552, and a protective cover 554 is arranged outside the driving wheel 551 and the driven wheel 552.

[0057] During use, when the motor 535 drives the reciprocating rod 532 to rotate through the gear set 534, the reciprocating rod 532 drives the driving wheel 551 to rotate together. The driving wheel 551 drives the driven wheel 552 to rotate through the transmission belt 553. The rotation of the driven wheel 552 provides power for the driving shaft 513, so that it drives the membrane body 515 to rotate in a cycle through the friction force on the inner surface of the membrane body 515. The protective cover 554 outside the driving wheel 551 and the driven wheel 552 protects them, preventing the alkaline wet material from polluting and corroding them.

[0058] In the specific implementation process, such as Figure 4 and Figure 7 As shown, a water receiving hopper 527 is arranged on one side of the neutralization tank 525 close to the membrane body 515. A water hanging strip 528 is arranged at the upper edge of the water receiving hopper 527, and the water hanging strip 528 is attached to the outer surface of the membrane body 515.

[0059] During use, after the neutralization tank 525 collects the rinsed wastewater, there will still be a large amount of residue on the surface of the membrane body 515. A large amount of wastewater residue will affect the wiping effect of the wiping component 53, and the wiping cotton strip 538 needs to be replaced frequently. The wastewater remaining on the outer surface of the membrane body 515 after rinsing will first pass through the water hanging strip 528. The water hanging strip 528 first hangs down a large amount of wastewater and flows into the neutralization tank 525 through the water receiving hopper 527 for collection, and a small amount is wiped off by the wiping component 53.

[0060] In a specific implementation process, such as Figure 6 shown, the diameter of the driving wheel 551 is smaller than that of the driven wheel 552.

[0061] During use, the diameter of the driving wheel 551 is smaller than that of the driven wheel 552. By using different diameters to adjust the moving speeds of the film body 515 and the wiping cotton strip 538, in the optimal case, when the wiping cotton strip 538 moves left and right for a round trip, the moving distance of the film body 515 is exactly equal to the length of the wiping cotton strip 538.

[0062] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
