Description

Technical Field

[0001] This invention relates to the field of Poria cocos peel processing technology, and in particular to a comprehensive inspection and selection system for Poria cocos peel. Background Technology

[0002] Poria peel is the outer skin of the sclerotium of the fungus Poria cocos. It has diuretic and swelling-reducing effects and can be used to treat edema and skin swelling. Poria peel is generally obtained by collecting and drying the outer skin that is peeled off during the processing of "Poria cocos slices" and "Poria cocos chunks".

[0003] To ensure the quality of Poria cocos peel during processing, color sorting and screening are necessary. Color sorting removes peels with defects or scars, yielding higher-quality peels. During color sorting, photoelectric detectors detect defects in the material, which are then removed through nozzles, resulting in the acquisition of normal peels. Since Poria cocos is in sheet form, defects do not affect the efficacy of other parts, nor do large or small pieces. Currently, color sorting equipment that removes entire pieces of peel wastes other parts and reduces the yield of normal peels. Summary of the Invention

[0004] This invention addresses the problem in existing Poria cocos peel color sorting equipment that removes entire pieces of Poria cocos peel during color sorting, resulting in a low yield of normal Poria cocos peel. The invention proposes a comprehensive Poria cocos peel sorting system to improve the yield of Poria cocos peel during color sorting.

[0013] The beneficial effects of this invention are:

[0014] 1. This comprehensive sorting system for Poria cocos peel is used for belt-type color sorting of Poria cocos peel. A dividing groove is set on the conveyor surface of the color sorting belt of the existing color sorting equipment. An intermediate color sorting is performed inside the dividing groove to select out large pieces of Poria cocos peel with defects. The large pieces of defective Poria cocos peel are then divided by the dividing blade to obtain small pieces of defective Poria cocos peel and small pieces of normal Poria cocos peel. Finally, the small pieces of defective Poria cocos peel and small pieces of normal Poria cocos peel are subjected to final color sorting, which can obtain more normal Poria cocos peel and improve the yield.

[0015] 2. The feeding power of the normal material feeding platform and the defective material conveyor belt inside the dividing tank of this Poria cocos peel comprehensive inspection and sorting system is driven by the rotation of the front support roller and the rear support roller through the color sorting track. The Poria cocos peels after intermediate color sorting can continue to enter the conveying surface of the color sorting track. The whole system has a compact structure.

[0016] 3. The dividing blade holder of this Poria cocos peel comprehensive inspection and sorting system can not only divide the defective Poria cocos peel on the defective material conveyor belt, but also physically separate them to reduce the entanglement of materials after subsequent conveying; at the same time, the dividing blade holder is equipped with defect detection scanners around the blade to prevent the blade from falling on the defect, reducing the number of small pieces of defective Poria cocos peel, obtaining more small pieces of normal Poria cocos peel, and further improving the yield of Poria cocos after color sorting.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Example 1

[0034] Reference Figure 1 The comprehensive sorting system for Poria cocos peel in this embodiment includes a color sorting equipment frame 1 and a feeding support 14 for color sorting Poria cocos peel. The feeding support 14 is inclined, with a lower feeding bin 13 at the feeding end of the feeding support 14 and an upper feeding bin 15 at the discharging end of the feeding support 14. The feeding support 14 is equipped with a conveyor belt. The feeding support 14 is used to feed the Poria cocos peel from the lower feeding bin 13 into the upper feeding bin 15 at the top of the frame 1, which facilitates the feeding of the color sorting equipment.

[0035] Furthermore, a color sorting conveyor belt 2 is installed on the frame 1 of the color sorting equipment. The color sorting conveyor belt 2 is located at the discharge end of the upper feed hopper 15. The Poria cocos peel inside the upper feed hopper 15 is slowly discharged and spread out on the color sorting conveyor belt 2.

[0036] The color sorting track 2 is supported and conveyed by conveyor rollers 16. A front steering roller 21, a rear steering roller 22, a front support roller 23, and a rear support roller 24 are arranged between the conveyor rollers 16. The front support roller 23 and the rear support roller 24 are located below the front steering roller 21 and the rear steering roller 22. The upper conveying surface of the color sorting track 2 sequentially passes through the front steering roller 21, the front support roller 23, the rear support roller 24, and the rear steering roller 22 to form a dividing groove 3.

[0037] refer to Figure 2 The dividing trough 3 is equipped with a normal material feeding platform 4 and a defective material conveyor belt 5. The normal material feeding platform 4 is located below the defective material conveyor belt 5. The inlet and outlet ends of the normal material feeding platform 4 and the defective material conveyor belt 5 are respectively connected to the upper conveying surface of the color sorting conveyor belt 2. An intermediate photoelectric detector 7 and a lifting nozzle 8 are installed between the inlet end of the normal material feeding platform 4 and the defective material conveyor belt 5 and the color sorting conveyor belt 2. The intermediate photoelectric detector 7 is used to detect defects in the Poria cocos peel, and the lifting nozzle 8 is used to blow the defective Poria cocos peel that comes out of the upper conveying surface of the color sorting conveyor belt 2 to the upper surface of the defective material conveyor belt 5. Normal Poria cocos peel that enters the dividing trough 3 from the upper conveying surface of the color sorting conveyor belt 2 enters the normal material feeding platform 4 due to gravity and the conveying speed of the color sorting conveyor belt 2.

[0038] Furthermore, the frame 1 is provided with a material platform bracket 17 for supporting the constant material feeding platform 4, as shown in the reference. Figure 2 and Figure 3The material platform support 17 is provided with a vibrating block 171 that is slidably connected to the material platform support 17 in the horizontal direction, and the vibrating block 171 is fixedly connected to the constant material feeding platform 4. The front end and rear end of the vibrating block 171 are respectively connected to the material platform support 17 via buffer elastic elements 174. The front end of the vibrating block 171 is provided with a front magnetic block 172, and the rear end of the vibrating block 171 is provided with a rear magnetic block 173.

[0039] The front support roller 23 and the rear support roller 24 are rotatably connected to the frame. When the color sorting track 2 passes over the front support roller 23 and the rear support roller 24, the friction between the color sorting track 2 and the front support roller 23 and the rear support roller 24 causes the front support roller 23 and the rear support roller 24 to rotate. Drive magnetic blocks 25 passing through the axis are respectively arranged inside the front support roller 23 and the rear support roller 24. The magnetic poles of the drive magnetic blocks 25 are symmetrically arranged on the front support roller 23 or the rear support roller 24. The drive magnetic blocks 25 form an attraction or repulsion with the front magnetic block 172 or the rear magnetic block 173 of the vibrating block 171.

[0040] The arrangement of the driving magnetic blocks 25 on the front support roller 23 and the rear support roller 24 satisfies the following conditions: when the driving magnetic block 25 of the front support roller 23 attracts the front magnetic block 172, the driving magnetic block 25 of the rear support roller 24 repels the rear magnetic block 173. When the driving magnetic block 25 of the front support roller 23 repels the front magnetic block 172, the driving magnetic block 25 of the rear support roller 24 attracts the rear magnetic block 173. The front support roller 23 and the rear support roller 24 rotate synchronously, and the rotation of the driving magnetic blocks 25 intermittently attracts and repels the front magnetic block 172 or the rear magnetic block 173, causing the vibrating block 171 to move back and forth horizontally, thus creating vibration. Consequently, the constant material feeding table 4 also forms a horizontal back and forth vibration state.

[0041] The upper surface of the constant material feeding platform 4 is a conveying surface, which is an inclined surface that is higher in the front and lower in the back. Because the front of the constant material feeding platform 4 is higher, when the constant material feeding platform 4 moves forward, the Poria cocos peel on the conveying surface of the constant material feeding platform 4 tends to move forward due to inertia. However, due to the friction between the Poria cocos peel and the conveying surface of the constant material feeding platform 4, the Poria cocos peel does not move forward. When the constant material feeding platform 4 moves backward, the Poria cocos peel tends to move backward. At this time, the horizontal movement of the Poria cocos peel will leave the conveying surface of the constant material feeding platform 4, and thus the Poria cocos peel will move backward, thereby forming the backward conveying of the Poria cocos peel.

[0042] refer to Figure 3 , Figure 4 and Figure 5An intermittent connecting assembly is provided between the normal material feeding platform 4 and the defective material conveyor belt 5. The intermittent connecting assembly includes a lower connecting block 41 fixedly connected to the normal material feeding platform 4 and an upper connecting block 51 fixedly connected to the side of the lower conveying surface of the defective material conveyor belt 5. The lower end of the upper connecting block 51 has a movable groove 52, and a movable block 53 that matches the movable groove 52 is provided. A connecting elastic element 54 is provided between one side of the movable block 53 and the movable groove 52, and a movable tooth 55 is provided on the other side of the movable block 53. A fixed tooth 42 that matches the movable tooth 55 is provided on one side of the lower connecting block 41. The connecting elastic element 54 abuts against the movable block 53, causing the movable tooth 55 to mesh with the fixed tooth 42.

[0043] refer to Figure 5 The rear tooth surface of the aforementioned movable tooth 55 is a plane, and the front tooth surface of the movable tooth 55 is an inclined plane. When the normal material feeding platform 4 moves backward, the fixed tooth 42 pushes the movable tooth 55 and the movable block 53 to move away from the fixed tooth 42, and the movable tooth 55 does not mesh with the fixed tooth 42; when the normal material feeding platform 4 moves forward, the movable tooth 55 and the fixed tooth 42 remain engaged, and the fixed tooth 42 pushes the movable tooth 55, the movable block 53, the upper connecting block 51, and the lower conveying surface of the defective material conveyor belt 5 to move forward together, so that the upper conveying surface of the defective material conveyor belt 5 can be conveyed backward.

[0044] Furthermore, a dividing blade holder 6 is provided above the defective material conveyor belt 5. The dividing blade holder 6 is connected to the frame 1 via a dividing cylinder 19, which is used to move the dividing blade holder 6 in the vertical direction. The dividing blade holder 6 is equipped with blades and is used to divide the large area of ​​defective Poria cocos peel on the defective material conveyor belt 5 into small pieces of defective Poria cocos peel and small pieces of normal Poria cocos peel.

[0045] refer to Figure 9 A limiting plate 56 is provided on the material conveyor belt 5. The limiting plate 56 is used to restrict the Poria cocos peel to the conveyor route where the dividing knife seat 6 is located, so that the dividing knife seat 6 can divide the Poria cocos peel.

[0046] In this embodiment, a vibration drive is provided between the discharge end of the color sorting track 2 and the rear steering roller 22 to generate vibration of the color sorting track 2, which helps the Poria cocos peel in the rear section of the color sorting track 2 to be laid flat and reduce stacking.

[0047] refer to Figure 1 The discharge end of the color sorting conveyor 2 is equipped with a discharge photoelectric detector 9, a discharge nozzle 10, a defective material box 11, and a normal material box 12. The discharge photoelectric detector 9 is used to detect defects in the Poria cocos peel, the discharge nozzle 10 is used to select out the defective Poria cocos peel and blow it into the interior of the defective material box 11, and the normal Poria cocos peel that comes out from the conveyor surface of the color sorting conveyor 2 enters the interior of the normal material box 12 due to gravity and the conveying speed of the color sorting conveyor 2.

[0048] The operation of the Poria cocos peel comprehensive selection system in this embodiment includes the following steps:

[0049] Step 1: Place the selected Poria cocos peel into the lower feed hopper 13, and the feeding bracket 14 will send the Poria cocos peel from the lower feed hopper 13 into the upper feed hopper 15 at the top of the frame 1.

[0050] Step 2: The Poria cocos peel inside the upper feed hopper 15 is slowly discharged and spread out on the color sorting conveyor 2;

[0051] Step 3: The Poria cocos peels on the color sorting conveyor 2 enter the dividing groove 3 with initial velocity. The photoelectric detector 7 in the middle detects the defects of the Poria cocos peels. Normal Poria cocos peels enter the normal material feeding table 4 due to gravity and initial velocity. Defective Poria cocos peels are blown to the upper surface of the defective material conveyor belt 5 by the lifting nozzle 8.

[0052] Step 4: The friction between the color sorting conveyor belt 2 and the front support roller 23 and the rear support roller 24 causes the front support roller 23 and the rear support roller 24 to rotate, driving the magnetic block 25 to rotate and form intermittent attraction and repulsion on the front magnetic block 172 or the rear magnetic block 173, forming the horizontal back and forth vibration of the normal material feeding platform 4, and the normal Poria cocos peel moves backward on the normal material feeding platform 4.

[0053] The vibration of the normal material feeding table 4 can also cause the lower conveying surface of the defective material conveyor belt 5 to move forward, thereby realizing the upper conveying surface of the defective material conveyor belt 5 to convey the defective material conveyor belt 5 backward. The defective Poria cocos skin enters the lower part of the dividing knife seat 6 under the restriction of the limiting plate 56. The dividing knife seat 6 divides the large area of ​​defective Poria cocos skin on the defective material conveyor belt 5 to obtain small pieces of defective Poria cocos skin and small pieces of normal Poria cocos skin.

[0054] Step 5: Normal Poria cocos peels on the normal material feeding platform 4 directly re-enter the upper conveyor surface of the color sorting conveyor 2, while small pieces of defective Poria cocos peels and small pieces of normal Poria cocos peels on the defective material conveyor 5 re-enter the color sorting conveyor 2.

[0055] Step Six: The Poria cocos peels arrive at the discharge end of the color sorting conveyor belt 2. The discharge photoelectric detector 9 detects defective Poria cocos peels, and the discharge nozzle 10 blows large and small pieces of defective Poria cocos peels into the defective material box 11. Normal Poria cocos peels enter the normal material box 12 due to gravity and the conveying speed of the color sorting conveyor belt 2.

[0056] Example 2

[0057] refer to Figure 6The dividing blade holder 6 includes an upper blade holder 61 located above the upper conveyor belt of the defective material conveyor belt 5 and a lower detection holder 62 located below the upper conveyor belt of the defective material conveyor belt 5. The upper blade holder 61 and the lower detection holder 62 are fixedly connected by a connecting plate 63. The defective material conveyor belt 5 is transparent to facilitate the lower detection holder 62 to detect the subcutaneous surface of Poria cocos on the defective material conveyor belt 5.

[0058] A pressure seat 613 is provided at the lower part of the upper tool holder 61. In this embodiment, both the pressure seat 613 and the lower detection seat 62 are circular. (See reference) Figure 7 The lower surface of the pressure base 613 is provided with four separating blocks 614, a central platform 615, and cross blades 616. The central platform 615 is fixedly disposed in the middle of the pressure base 613, and the cross blades 616 are fixedly disposed on the central platform 615. The separating blocks 614 are located between the blades of the cross blades 616, and the separating blocks 614 are movably connected to the pressure base 613 in the horizontal direction. The cross blades 616 are used to cut the defective Poria cocos peel into four small pieces. The movable separating blocks 614 are used to separate the divided small pieces of Poria cocos peel, facilitating color sorting at the discharge end. The lower surface of the separating blocks 614 is provided with contact bristles 617, which are used to directly and flexibly contact the Poria cocos peel to reduce damage to the peel. The tips of the cross blades 616 are lower than the lower surface of the separating blocks 614 and the tips of the contact bristles 617.

[0059] Furthermore, an upper scanner 618 is provided on the intermediate stage 615, which is used to identify defects on the surface of the Poria cocos peel. (Reference) Figure 8 The lower detection seat 62 and the pressure seat 613 are opposite each other, and a lower scanner 621 is provided. The position of the lower scanner 621 corresponds to the position of the upper scanner 618. The lower scanner 621 is used to identify defects on the subcutaneous surface of Poria cocos skin. The upper scanner 618 is located between the cross blade 616 and each of the separation blocks 614, that is, on both sides of the blade of the cross blade 616. When the blade is cut, it avoids the blade from falling on defects, so that it falls on one small piece of Poria cocos skin after cutting as much as possible, reducing the number of small pieces of Poria cocos skin with defects, obtaining more small pieces of normal Poria cocos skin, and improving the yield of Poria cocos after color sorting.

[0060] To achieve active separation of separation block 614, refer to Figure 6 A fixed seat 611 is provided on the upper part of the upper knife holder 61, and a separation cylinder 612 is provided below the fixed seat 611. A supporting elastic element 6112 is provided between the fixed seat 611 and the separation cylinder 612. The fixed seat 611 is fixedly connected to the guide block 6113 through the connecting rod 6111. The guide block 6113 is located inside the separation cylinder 612 and is slidably connected to the separation cylinder 612 in the vertical direction.

[0061] Furthermore, the pressure seat 613 is internally provided with a sliding groove 6131 and a slider 6132 that matches the sliding groove 6131. ​​The extension direction of the sliding groove 6131 and the movement direction of the slider 6132 pass through the center of the pressure seat 613. The lower end of the slider 6132 is fixedly connected to the separation block 614. One end of the slider 6132 is connected to the groove wall of the sliding groove 6131 through a return elastic element 6133. The other end of the slider 6132 is hinged to one end of the connecting rod 6134. The other end of the connecting rod 6134 is hinged to the lower end of the separation starting rod 6135. The upper end of the separation starting rod 6135 is fixedly connected to the guide block 6113.

[0062] In this embodiment, when the defective Poria cocos peel passes through the dividing blade holder 6, the upper scanner 618 and the lower scanner 621 scan the defective Poria cocos peel. After the defect passes through the blade, the dividing cylinder 19 presses down for the first time, pushing the dividing blade holder 6 to divide the Poria cocos peel. After the division is completed, the dividing cylinder 19 presses down for the second time, the supporting elastic element 6112 contracts, and the guide block 6113 pushes the separation starting rod 6135 to move downward. The separation starting rod 6135 pushes the slider 6132 and the separating block 614 through the connecting rod 6134. The separating block 614 leaves the intermediate platform 615, and the separating block 614 drives the small pieces of Poria cocos peel below to separate, which facilitates subsequent color sorting.
