Description

Technical Field

[0001] The invention relates to the technical field of indigo leaf production and sorting, and in particular to an automatic sorting device for indigo leaf production. Background Art

[0002] Reed leaves are the most commonly used rice dumplings leaves in the Jiangnan area. The leaves are basically round, large, with fine hairs on the back, 10-35 cm long and about 2-5 cm wide. The leaves are relatively wide, making them very suitable for wrapping the triangular and square rice dumplings popular in the Jiangnan area. Reed leaves can not only be used to wrap rice dumplings, but are also a Chinese medicine. Reed leaves have the effect of promoting blood circulation and unblocking meridians. They have a good effect on headaches, toothaches, hot coughs and heatstroke. After being picked, the reed leaves will be transported to the processing plant through a conveyor for processing.

[0003] For example, the publication number CN221955115U discloses an automatic conveying device for processing indigo leaves, including a workbench, a feeding device is provided on the workbench, a first conveyor belt is provided on the workbench, a conveying mechanism is provided on the workbench, a cleaning device is provided on the workbench, and a collecting tank is fixedly connected to the workbench. By controlling the motor to start operation, the tooth plate is driven to move, and the indigo leaves are transferred to the tooth plate to achieve feeding, and three tooth plates are provided to achieve the effect of continuous feeding, thereby enhancing the efficiency of work. By setting a second conveyor belt, the effect of automatically conveying the indigo leaves can be enhanced, thereby enhancing the work efficiency. By controlling the submersible pump to start operation, the water in the water tank is extracted and transferred to the spray head, the indigo leaves below are sprayed, the surface of the indigo leaves is cleaned, and then the indigo leaves after cleaning are collected through the set collecting tank.

[0004] Indigofera leaves contain moisture and are easily stuck to the conveyor belt. If they stick to the conveyor belt, it will be inconvenient to sort them, which will affect the sorting efficiency. In addition, it will be difficult to separate them from the conveyor belt during unloading, resulting in low sorting and conveying efficiency. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an automatic sorting device for the production of indigo leaves in view of the deficiencies in the above-mentioned prior art.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: an automatic sorting device for producing indigo leaves, comprising a bottom plate, the top of the bottom plate is fixedly connected to two vertical plates, a three-stage conveyor belt is arranged between the two vertical plates, the tops of the two vertical plates are fixedly connected to a support frame, the bottom of the support frame is fixedly connected to a visual detection camera, the top of the vertical plate is fixedly connected to a fixed plate, the back of the fixed plate is fixedly connected to a first telescopic rod, one end of the first telescopic rod is fixedly connected to a first connecting plate, the bottom of the first connecting plate is fixedly connected to a second telescopic rod, the bottom of the second telescopic rod is fixedly connected to a second connecting plate, and the bottom of the second connecting plate A suction cup is fixedly connected, and when the indigo leaves pass the bottom of the visual inspection camera and a defect of the indigo leaves is detected, the indigo leaves are adsorbed by the suction cup, and the indigo leaves at the bottom of the suction cup are driven to be sorted by the first telescopic rod, thereby realizing the sorting of defective indigo leaves, and an anti-sticking mechanism is arranged on the top of the bottom plate, and the anti-sticking mechanism comprises a cylinder, and a connecting rod is fixedly connected to the output end of the cylinder, and one end of the connecting rod is fixedly connected to a top plate, and the connecting rod is driven to lift and move by the cylinder, thereby driving the top plate to move up and down by the connecting rod, and the indigo leaves at the top of the three-stage conveyor belt can be lifted up by the up and down movement of the top plate, thereby reducing the adhesion between the indigo leaves and the three-stage conveyor belt.

[0007] Preferably, a plurality of longitudinal holes are opened inside the top plate, a sliding rod is fixedly connected inside the longitudinal hole, and a sliding sleeve is movably sleeved on the outer wall of the sliding rod.

[0008] Preferably, the top of the sliding sleeve is fixedly connected with a top block, and a support rod is hinged between the sliding sleeve and the top of the bottom plate. The up and down movement of the top plate will drive the sliding sleeve to slide on the sliding rod through the support rod, thereby driving the top block on the top of the sliding sleeve to move longitudinally and drive one end of the bamboo leaf to be lifted, thereby promoting the separation effect of the bamboo leaf and the three-stage conveyor belt.

[0009] Preferably, a scraping mechanism is provided on the top of the bottom plate, and the scraping mechanism includes a transverse groove, which is opened on the vertical plate, and a first slider is slidably connected inside the transverse groove, and a first spring is fixedly connected between the first slider and the transverse groove, and a scraper is fixedly connected to the front of the first slider, and the scraper is fitted with the three-stage conveyor belt. By setting the scraper, the sticky moisture and impurities on the three-stage conveyor belt can be scraped and cleaned, thereby reducing the stickiness of the bamboo leaves.

The scraper always keeps in contact with the three-stage conveyor belt. When the top plate rises, the folding rod will be driven to rise, so that the first protrusion will be out of contact with the contact plate, so that the scraper will apply a slight pressure to the three-stage conveyor belt under the elastic action of the first spring, and a vibration force will be formed over a long period of time. The slight vibration will make the scraper more helpful in breaking the surface tension of the water, making it easier to separate the moisture from the surface of the conveyor belt. For some moisture with strong viscosity or attached to the texture of the conveyor belt, the vibration can loosen it, making it easier for the scraper to scrape it off, thereby improving the thoroughness of scraping.

[0011] Preferably, the vertical plate is provided with an arc groove, the inside of the arc groove is slidably connected with a ball, the outer wall of the ball is fixedly connected with the arc groove, and a second spring is fixedly connected between the outer wall of the ball and the arc groove, and the outer wall of the ball is fixedly connected with a cross bar, and the outer wall of the cross bar is fixedly connected with the first push plate, and the outer wall of the cross bar is provided with a first torsion spring, and the outer wall of the cross bar is affixed with the top of the first push plate. The first push plate is arranged to move on the scraper to scrape moisture impurities and the like into the collection box. The first push plate in the current figure is in a cleaned state. When the folding rod is lifted, the first push plate will be reset under the elastic reset action of the second spring, so that the first push plate and the scraper maintain a non-contact state. The non-contact is to avoid affecting the circulation of moisture and impurities. When the folding rod descends, it will contact the first push plate, so that the first push plate will descend accordingly, thereby contacting the scraper, and maintain a certain angle under the limiting action of the first torsion spring to move on the scraper to scrape moisture impurities into the collection box, thereby avoiding affecting the scraping effect of the scraper due to impurities.

[0012] Preferably, a shaking mechanism is provided at the top of the bottom plate, and the shaking mechanism includes two support plates, the two support plates are fixedly connected to the top of the bottom plate, a sieve plate is rotatably connected between the two support plates, a second torsion spring is provided between the sieve plate and the support plates, and a resistance rod is fixedly connected to the bottom of the top plate, and the resistance rod is provided at the bottom of the sieve plate. The indigo leaves pass through the sieve plate and then flow to the three-stage conveyor belt. The up and down movement of the top plate will drive the up and down movement of the resistance rod, which will drive the sieve plate to rotate up and down, thereby realizing the shaking of the indigo leaves, and the moisture sticking on the indigo leaves flows out from the holes inside the sieve plate, reducing the moisture on the indigo leaves, thereby reducing the adhesion between the indigo leaves and the three-stage conveyor belt.

[0013] Preferably, two horizontal plates are fixedly connected to the top of the sieve plate, a second push plate is hinged on one side of the horizontal plate, the second push plate is fitted with the top of the sieve plate, a third spring is fixedly connected between the second push plate and the horizontal plate, a fixing rod is hinged on one side of the second push plate, a second protrusion is fixedly connected on one side of the two vertical plates, the second protrusion is in contact with the fixing rod, and when the sieve plate rotates, it drives the fixing rod to move up and down, so that the fixing rod drives the second push plate to push inward under the action of the second protrusion, and the bamboo leaves can be automatically gathered to the middle by the second push plate to prevent them from piling up on the edge in the early stage of transportation, ensuring that the bamboo leaves are evenly distributed when entering the conveyor belt, laying the foundation for the subsequent stable and efficient sorting process, and at the same time reducing the burden of moisture processing in subsequent processes.

[0014] The present invention adopts the above technical solution to bring the following beneficial effects:

[0015] 1. The automatic sorting device for the production of indigo leaves lifts up the indigo leaves and separates them from the three-stage conveyor belt by moving the top plate up and down, directly acts on the indigo leaves on the three-stage conveyor belt, periodically reduces the pressure between the indigo leaves and the conveyor belt, destroys the sticky interface that may be formed, and then drives the longitudinal movement of the top block to achieve longitudinal lifting of one end of the indigo leaves, cleverly destroys the adhesion between the indigo leaves and the conveyor belt, promotes the smooth separation of the indigo leaves, and promotes the separation of the indigo leaves from the conveyor belt from multiple angles, preventing the indigo leaves from adhering to the conveyor belt due to moisture or their own viscosity, thereby ensuring the smoothness of the indigo leaf transportation, thereby improving the sorting efficiency and transportation efficiency by reducing the adhesion between the indigo leaves and the three-stage conveyor belt.

[0016] 2. This automatic sorting device for the production of indigo leaves can continuously scrape off impurities such as moisture, dust, and broken leaves on the surface, keep the conveyor belt clean, avoid secondary contamination of the indigo leaves, and maintain the cleanliness of the indigo leaves during the transmission process, which is conducive to sorting and conveying the indigo leaves. The slight vibration generated by the scraper cleverly uses the vibration characteristics to break the surface tension of the water, making it easier for sticky moisture to leave the conveyor belt, while loosening impurities attached to the deep texture of the conveyor belt, allowing the scraper to scrape more thoroughly and improve cleaning efficiency.

[0017] 3. This automatic sorting device for the production of indigo leaves can push the scraped impurities to the collection box in time through the automatic cleaning action of the first push plate, preventing them from accumulating at the scraper and affecting the scraping effect, thereby ensuring that the scraping mechanism operates stably and efficiently for a long time.

[0018] 4. The automatic sorting device for the production of indigo leaves shakes off a large amount of water carried by the indigo leaves by shaking the sieve plate, allowing the water to be discharged through the holes in the sieve plate, thereby reducing the overall humidity of the indigo leaves, thereby reducing the adhesion between the indigo leaves and the three-stage conveyor belt, to improve the sorting and conveying efficiency. During the rotation of the sieve plate, the second push plate can automatically gather the indigo leaves to the middle to prevent them from accumulating at the edge in the early stage of transportation, ensuring that the indigo leaves are evenly distributed when entering the conveyor belt, laying the foundation for the subsequent stable and efficient sorting process, while reducing the burden of moisture processing in subsequent processes.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-8 One embodiment of the present invention is: an automatic sorting device for producing indigo leaves, comprising a bottom plate 1, two vertical plates 2 are fixedly connected to the top of the bottom plate 1, a three-stage conveyor belt 3 is arranged between the two vertical plates 2, a support frame 41 is fixedly connected to the top of the two vertical plates 2, a visual detection camera 42 is fixedly connected to the bottom of the support frame 41, a fixed plate 43 is fixedly connected to the top of the vertical plate 2, a first telescopic rod 44 is fixedly connected to the back of the fixed plate 43, one end of the first telescopic rod 44 is fixedly connected to the first connecting plate 45, and the first The bottom of the connecting plate 45 is fixedly connected with a second telescopic rod 46, the bottom of the second telescopic rod 46 is fixedly connected with a second connecting plate 47, the bottom of the second connecting plate 47 is fixedly connected with a suction cup 48, when the indigo leaf passes the bottom of the visual detection camera 42, when the defect of the indigo leaf is detected, the indigo leaf is adsorbed by the suction cup 48, and the indigo leaf at the bottom of the suction cup 48 is driven by the first telescopic rod 44 to be sorted, so as to realize the sorting of defective indigo leaves, the top of the bottom plate 1 is provided with an anti-sticking mechanism 5, and the anti-sticking mechanism 5 includes a cylinder 5 11, the output end of the cylinder 511 is fixedly connected to a connecting rod 512, one end of the connecting rod 512 is fixedly connected to a top plate 513, the cylinder 511 drives the connecting rod 512 to move up and down, thereby driving the top plate 513 to move up and down through the connecting rod 512, and the top plate 513 can drive the indigo leaves on the top of the three-stage conveyor belt 3 to be lifted up through the up and down movement of the top plate 513, thereby reducing the adhesion between the indigo leaves and the three-stage conveyor belt 3, and a plurality of longitudinal holes 514 are opened inside the top plate 513, and the inner part of the longitudinal holes 514 is fixed A sliding rod 515 is fixedly connected, and a sliding sleeve 516 is movably sleeved on the outer wall of the sliding rod 515. A top block 517 is fixedly connected to the top of the sliding sleeve 516. A support rod 518 is hinged between the sliding sleeve 516 and the top of the bottom plate 1. The up and down movement of the top plate 513 will drive the sliding sleeve 516 to slide on the sliding rod 515 through the support rod 518, thereby driving the top block 517 on the top of the sliding sleeve 516 to move longitudinally, driving one end of the indigo leaf to be lifted, thereby promoting the separation effect of the indigo leaf and the three-stage conveyor belt 3.

[0030] Working principle: When the indigo leaves start to be transported along with the three-stage conveyor belt 3 and pass under the visual inspection camera 42, the visual inspection camera 42 will conduct a comprehensive scan of the indigo leaves. Once defects such as damage, insect infestation, etc. are detected in the indigo leaves, the control system will immediately issue a command. At this time, the second telescopic rod 46 drives the second connecting plate 47 and the suction cup 48 at the bottom to descend, so that the suction cup 48 is in close contact with the defective indigo leaves and adsorbs them. Subsequently, the first telescopic rod 44 is started, driving the first connecting plate 45 and the adsorbed indigo leaves to move to the specified position, completing the sorting of the defective indigo leaves, ensuring that the quality of the indigo leaves entering the subsequent processing link meets the requirements, and the cylinder 511 is started, and its output end drives the connecting rod 512 to do a lifting movement, thereby causing the top plate 513 connected to the connecting rod 512 to move up and down. When the top plate 513 rises, it directly acts on the indigo leaves on the three-stage conveyor belt 3, partially lifting it, periodically reducing the pressure between the indigo leaves and the three-stage conveyor belt 3, destroying the sticky interface that may be formed, and when the top plate 513 moves up and down, the support rod 518 drives the sliding sleeve 516 to slide on the sliding rod 515, so that the top block 517 moves longitudinally, further lifting one end of the indigo leaves from multiple angles. This multi-dimensional action makes it easier to separate the indigo leaves from the three-stage conveyor belt 3, avoids the indigo leaves from adhering to the three-stage conveyor belt 3 due to moisture or self-stickiness, ensures the smoothness of the indigo leaf transportation, and effectively improves the sorting and transportation efficiency.

[0031] See also Figure 1-8On the basis of the above embodiment, in another embodiment of the present invention, a scraping mechanism 6 is provided on the top of the bottom plate 1, and the scraping mechanism 6 includes a transverse groove 611, and the transverse groove 611 is opened on the vertical plate 2. A first slider 612 is slidably connected inside the transverse groove 611, and a first spring 613 is fixedly connected between the first slider 612 and the transverse groove 611. A scraper 614 is fixedly connected to the front of the first slider 612, and the scraper 614 is in contact with the three-stage conveyor belt 3. By setting the scraper 614, the moisture and impurities sticking on the three-stage conveyor belt 3 can be scraped and cleaned, thereby reducing the sticking effect on the indigo leaves. A folding rod 615 is fixedly connected to the bottom of the top plate 513, and a contact plate 6 is fixedly connected to the outer wall of the folding rod 615. 16. One end of the scraper 614 is fixedly connected with a first protrusion 617, which contacts with the contact plate 616. The top of the bottom plate 1 is fixedly connected with a collecting box 618. The scraper 614 always keeps in contact with the three-stage conveyor belt 3. When the top plate 513 rises, the folding rod 615 is driven to rise, so that the first protrusion 617 is out of contact with the contact plate 616, so that the scraper 614 is subjected to a slight applied pressure under the elastic action of the first spring 613. A vibration force is formed over a long period of time. The vibration makes the scraper 614 produce a tiny high-frequency vibration at the moment of contact with the conveyor belt, which helps to break the surface tension of the water and makes it easier to separate the water from the surface of the conveyor belt. For some water with strong viscosity or attached to the texture of the conveyor belt, vibration can loosen it, making it easier for the scraper 614 to scrape it off, thereby improving the thoroughness of scraping. An arc groove 619 is provided on the vertical plate 2, and a ball 620 is slidably connected inside the arc groove 619. A second spring 621 is fixedly connected between the outer wall of the ball 620 and the arc groove 619, and a cross bar 622 is fixedly connected to the outer wall of the ball 620. A first push plate 623 is fixedly connected to the outer wall of the cross bar 622. A first torsion spring 624 is provided on the outer wall of the cross bar 622. The outer wall of the folding rod 615 is in contact with the top of the first push plate 623. The first push plate 623 is arranged to move on the scraper 614 so that water impurities can be scraped off The collecting box 618 comes, and the first push plate 623 in the current figure is in a cleaned state. When the folding rod 615 is lifted, the first push plate 623 will be reset under the elastic reset action of the second spring 621, so that the first push plate 623 and the scraper 614 maintain a non-contact state. The non-contact is to avoid affecting the circulation of moisture and impurities. When the folding rod 615 descends, it will contact the first push plate 623, so that the first push plate 623 will descend accordingly, thereby contacting the scraper 614, and under the limiting action of the first torsion spring 624, it maintains a certain angle and moves on the scraper 614 to scrape the moisture impurities into the collecting box 618, thereby avoiding the scraping effect of the scraper 614 being affected by impurities.

[0032] Working principle: When the three-stage conveyor belt 3 rotates, the scraper 614 that is always in contact with the three-stage conveyor belt 3 will continue to scrape off the moisture and impurities on its surface. In the initial state, the contact plate 616 on the folding rod 615 at the bottom of the top plate 513 is in contact with the first protrusion 617 at one end of the scraper 614. When the top plate 513 rises and drives the folding rod 615 to rise, the contact plate 616 and the first protrusion 617 are out of contact. At this time, the scraper 614 moves to the left under the elastic action of the first spring 613, which enhances the scraping force between the scraper 614 and the three-stage conveyor belt 3. Over time, this reciprocating elastic action will cause the scraper 614 to vibrate slightly. The tiny high-frequency vibrations generated by the vibration help break the surface tension of the water, making it easier for the moisture to separate from the surface of the conveyor belt. For water that is highly sticky or attached to the texture of the conveyor belt, vibration can also loosen it, allowing the scraper 614 to scrape it off more easily, significantly improving the thoroughness of scraping. Figure 5 The first push plate 623 is in a cleaning state. When the folding rod 615 is lifted, the first push plate 623 is reset under the elastic reset action of the second spring 621, and keeps a non-contact state with the scraper 614 to avoid affecting the normal circulation of water and impurities. When the folding rod 615 drops and hits the first push plate 623, the first push plate 623 drops accordingly and hits the scraper 614. Under the limiting action of the first torsion spring 624, the first push plate 623 moves on the scraper 614 at a certain angle, pushing the scraped water and impurities to the collection box 618, avoiding the accumulation of impurities affecting the scraping effect of the scraper 614.

[0033] See also Figure 1-8, on the basis of the above embodiments, in another embodiment of the present invention, a shaking mechanism 7 is provided on the top of the bottom plate 1. The shaking mechanism 7 includes two support plates 711. The two support plates 711 are fixedly connected to the top of the bottom plate 1. A sieve plate 712 is rotatably connected between the two support plates 711. A second torsion spring 713 is provided between the sieve plate 712 and the support plate 711. The bottom of the top plate 513 is fixedly connected with a contact rod 714. The contact rod 714 is arranged at the bottom of the sieve plate 712. The bamboo leaves pass through the sieve plate 712 and then flow onto the three-stage conveyor belt 3. The up and down movement of the top plate 513 will drive the up and down movement of the contact rod 714, which will drive the sieve plate 712 to rotate up and down, so as to realize the shaking of the bamboo leaves, and the water adhered to the bamboo leaves will flow out through the holes inside the sieve plate 712, reducing the water on the bamboo leaves, thereby reducing the adhesion force between the bamboo leaves and the three-stage conveyor belt 3. Two cross plates 715 are fixedly connected to the top of the sieve plate 712. One side of the cross plate 715 is hinged with a second push plate 716. The second push plate 716 is attached to the top of the sieve plate 712. A third spring 717 is fixedly connected between the second push plate 716 and the cross plate 715. One side of the second push plate 716 is hinged with a fixing rod 718. One side of the two vertical plates 2 is fixedly connected with a second convex block 719. The second convex block 719 contacts the fixing rod 718. When the sieve plate 712 rotates, it will drive the fixing rod 718 to move up and down, so that the fixing rod 718 drives the second push plate 716 to push inward under the action of the second convex block 719. The second push plate 716 can automatically gather the bamboo leaves in the middle, preventing them from accumulating at the edge during the early stage of transportation, ensuring that the bamboo leaves are evenly distributed when entering the conveyor belt, laying a foundation for the subsequent stable and efficient sorting process, and at the same time reducing the burden of subsequent processes in dealing with water.

[0034] Working principle: The bamboo leaves flow onto the three-stage conveyor belt 3 from the sieve plate 712. The up and down movement of the top plate 513 will drive the up and down movement of the contact rod 714, which will drive the sieve plate 712 to rotate up and down, so as to realize the shaking of the bamboo leaves. Through the shaking of the sieve plate 712, a large amount of water carried by the bamboo leaves themselves is shaken off, and it is discharged through the holes of the sieve plate 712, reducing the overall humidity of the bamboo leaves, thereby reducing the adhesion force between the bamboo leaves and the three-stage conveyor belt 3, improving the sorting and conveying efficiency. When the sieve plate 712 rotates, it will drive the fixing rod 718 to move up and down, so that the fixing rod 718 drives the second push plate 716 to push inward under the action of the second convex block 719. The second push plate 716 can automatically gather the bamboo leaves on both sides in the middle, preventing the bamboo leaves from accumulating at the edge during the early stage of transportation, ensuring that the bamboo leaves are evenly distributed when entering the conveyor belt, laying a foundation for the subsequent stable and efficient sorting process, and at the same time reducing the burden of subsequent processes in dealing with water.

The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention. All components not specified in this embodiment can be implemented by existing technologies.
