Description

Technical Field

[0001] This utility model relates to the technical field of pearl sorting equipment, and in particular to a pearl grading, sorting and conveying device. Background Technology

[0002] Pearls are the only organic gemstones formed naturally by living organisms. They are known as the spirits of the ocean and the queen of jewels. Unlike mineral gemstones such as diamonds and jade, pearls are born inside mollusks and carry the unique imprint of life and time. From a classification perspective, pearls can be divided into two main categories according to their production environment: seawater pearls and freshwater pearls. According to their formation method, they can be divided into natural pearls and cultured pearls. Most pearls on the market today are cultured pearls. They are formed by artificially implanting a nucleus or a small piece of the mantle to guide the mollusc to secrete a pearl layer. Grading and sorting are the key links that determine the value of pearls.

[0003] However, existing technologies still have the following problems: After the pearls are removed, pearls of different sizes will be mixed together. At this time, the pearls need to be graded and sorted. Generally, this is done by filtering and sorting through multi-level filter plates. However, in actual applications, it is difficult to conveniently adjust the filter plate pore size according to actual needs, resulting in poor sorting effect and difficulty in easily moving the pearls. The filtering and sorting process is relatively slow, the sorting efficiency is low, and production time and costs are increased. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a pearl grading, sorting, and conveying device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pearl grading and sorting conveying device, comprising a conveyor body, a first filter box fixedly connected to the top surface of the conveyor body, a second filter box provided on one side of the conveyor body, a fixed filter plate fixedly connected to the inner surface of both the first and second filter boxes, a movable filter plate slidably connected to the bottom surface of the fixed filter plate, a pusher plate fixedly connected to one side surface of the movable filter plate, a fitting box movably connected to the outer surface of the pusher plate, a first guide mechanism provided on the top surface of both the first and second filter boxes, a second guide mechanism provided below the first guide mechanism, both the second and first guide mechanisms including a guide box, a servo motor fixedly connected to one end of the guide box, a lead screw body provided in the inner cavity of the guide box, a moving plate provided below the second guide mechanism, and a toggle plate fixedly connected to the bottom surface of the moving plate.

[0006] Furthermore, inclined guide plates are fixedly connected to the inner surfaces of the first and second filter boxes, and a slot is formed on the bottom surfaces of both the first and second filter boxes.

[0008] Furthermore, the fixed filter plate has a first filter hole through its top surface, and the movable filter plate has a second filter hole through its top surface, the second filter hole having a structural size that matches that of the first filter hole.

[0009] By adopting the above technical solution, the first filter hole and the second filter hole are staggered, which makes it easy to adjust the size of the filter hole.

[0010] Furthermore, the top surface of the push plate is coated with a scale layer, and an anti-detachment plate is fixedly connected to the surface of the movable filter plate away from the push plate. The anti-detachment plate has a T-shaped vertical cross-section.

[0011] By adopting the above technical solution, the movement of the anti-detachment plate can be more accurately propelled through the scale layer.

[0012] Furthermore, a tightening screw is threaded through the top surface of the socket box, a rotating rod is fixedly connected to the outer surface of the top end of the tightening screw, and an anti-slip soft layer is fixedly connected to the bottom end of the tightening screw.

[0013] By adopting the above technical solution, the screw can be rotated and tightened more effectively by rotating the rod.

[0014] Furthermore, one end of each of the four lead screws is fixedly connected to the output end of the four servo motors, and a bearing body is provided on the outer surface of the end of each of the four lead screws away from the servo motors.

[0015] By adopting the above technical solution, the four lead screws are movably connected to the guide box through bearing bodies.

[0016] Furthermore, a sleeve block is fixedly connected to the top surface of the motion plate, and a screw hole matching the structural size of the lead screw is opened through one side surface of the sleeve block.

[0017] By adopting the above technical solutions, the movement of the motion plate assembly can be better driven.

[0018] Furthermore, a silicone soft layer is fitted and fixedly connected to the outer surface of the actuating plate, and the bottom surface of the actuating plate is slidably connected to the fixed filter plate.

[0019] By adopting the above technical solution, the silicone soft layer avoids damage to the pearl body by the agitator.

[0020] In summary, this utility model has the following beneficial effects: 1. In this application, a first filter box and a second filter box are provided, and each filter box is equipped with a fixed filter plate and a movable filter plate. The fixed filter plate and the movable filter plate are respectively provided with a first filter hole and a second filter hole. The operator can precisely control the moving distance of the push plate according to the scale layer, and then precisely adjust the position of the movable filter plate so that the second filter hole partially or completely overlaps with the first filter hole, thereby changing the size of the filter hole diameter, realizing multi-level precise grading of pearls, and precisely controlling the size of the filter hole, thus improving the accuracy of grading and sorting. 2. In this application, by setting a first guiding mechanism, a second guiding mechanism, a moving plate and a toggle plate, with the first guiding mechanism and the second guiding mechanism arranged vertically, the movement direction and position of the toggle plate can be controlled as needed, so that the pearls pass through the filter holes more quickly during the filtration process, avoiding pearl accumulation or disorder, and improving sorting efficiency.

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] like Figure 1-5As shown in the figure, this application discloses a pearl grading, sorting and conveying device, including a conveyor body 1. The conveyor body 1 is a well-known and common conveyor belt conveyor for conveying and transporting pearls, which will not be described in detail here. A first filter box 2 is fixedly connected to the top surface of the conveyor body 1, and a second filter box 3 is provided on one side of the conveyor body 1. Inclined guide plates 12 are fixedly connected to the inner surfaces of the first filter box 2 and the second filter box 3. A straight groove is opened on the bottom surface of the first filter box 2 and the bottom surface of the second filter box 3. After sorting, the pearls fall into the collection areas corresponding to the straight grooves opened on the bottom surfaces of the first filter box 2 and the second filter box 3, and quickly enter the straight grooves through the guidance of the inclined guide plates 12.

[0025] Fixed filter plates 4 are fixedly connected to the inner surfaces of the first filter box 2 and the second filter box 3. A movable filter plate 5 is slidably connected to the bottom surface of the fixed filter plate 4. A first filter hole 13 is formed through the top surface of the fixed filter plate 4, and a second filter hole 14 is formed through the top surface of the movable filter plate 5. The second filter hole 14 matches the structure and size of the first filter hole 13. The second filter hole 14 and the first filter hole 13 can be circular or square holes, etc., depending on the actual construction needs. A push plate 6 is fixedly connected to one side surface of the movable filter plate 5. The top surface of the push plate 6 is coated with a scale layer. An anti-detachment plate 15 is fixedly connected to the side surface of the movable filter plate 5 away from the push plate 6. The anti-detachment plate 15 has a T-shaped vertical cross-section. One end of the anti-detachment plate 15 is movably connected to the first filter box 2. Alternatively, a second filter box 3 can be used to ensure the stability of the movement of the moving filter plate 5. Based on the scale layer coated on the top surface of the push plate 6, the movement distance of the push plate 6 within the fitting box 7 can be precisely controlled. As the push plate 6 moves, the moving filter plate 5 will also move accordingly, thereby causing the second filter hole 14 through the top surface of the moving filter plate 5 to partially or completely overlap with the first filter hole 13 through the top surface of the fixed filter plate 4, thus changing the size of the filter hole diameter. The fitting box 7 is movably connected to the outer surface of the push plate 6. A tightening screw 16 is threaded through the top surface of the fitting box 7. A rotating rod is fixedly connected to the outer surface of the top end of the tightening screw 16. An anti-slip soft layer made of rubber is fixedly connected to the bottom end of the tightening screw 16 to better prevent the push plate 6 from moving easily.

[0026] Both the top surfaces of the first filter box 2 and the second filter box 3 are provided with a first guide mechanism 8. Below the first guide mechanism 8 is a second guide mechanism 9. Both the second guide mechanism 9 and the first guide mechanism 8 include a guide box 91. A servo motor 92 is fixedly connected to one end of the guide box 91. A lead screw body 93 is provided inside the guide box 91. One end of each of the four lead screw bodies 93 is fixedly connected to the output end of one of the four servo motors 92. Bearings are provided on the outer surfaces of the ends of the four lead screw bodies 93 away from the servo motors 92. The four lead screw bodies 93 are movably connected to the four guide boxes 91 through the bearings. A motion plate 10 is provided below the second guide mechanism 9. A sleeve block 17 is fixedly connected to the top surface of the motion plate 10. A through-hole opening is provided on one side surface of the sleeve block 17 for connecting with the lead screw. The screw hole matches the structural dimensions of the body 93. The top surface of the guide box 91 in the second guide mechanism 9 is also fixedly connected with the sleeve block 17. The sleeve block 17 on the guide box 91 of the second guide mechanism 9 and the sleeve block 17 on the motion plate 10 are both threadedly connected to the outer surface of the screw body 93. When the screw body 93 of the second guide mechanism 9 rotates, it drives the sleeve block 17 and the motion plate 10 to move laterally. When the screw body 93 of the first guide mechanism 8 rotates, it drives the motion plate 10 and the actuating plate 11 assembly to move back and forth. The actuating plate 11 is fixedly connected to the bottom surface of the motion plate 10. A silicone soft layer is fixedly connected to the outer surface of the actuating plate 11. The bottom surface of the actuating plate 11 is slidably connected to the fixed filter plate 4. The silicone soft layer avoids damage to the pearl.

[0027] It should be noted that, with the help of those skilled in the art, all electrical components in this case, such as the servo motor 92 and the transmission body 1, should be connected to their compatible power supplies via wires. Furthermore, a suitable controller, such as a PLC controller or a microcontroller, should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0028] The working principle of the pearl grading and sorting conveying device in this embodiment is as follows: When in use, the operator first adjusts the filter aperture in the first filter box 2 and the second filter box 3 according to the different specifications of the pearls to be sorted. Furthermore, the operator can precisely control the movement distance of the push plate 6 within the housing 7 according to the scale layer. As the push plate 6 moves, the movable filter plate 5 connected to it will also slide against the bottom surface of the fixed filter plate 4. The top surface of the movable filter plate 5 is provided with a second filter hole 14, and the top surface of the fixed filter plate 4 is provided with a first filter hole 13. By adjusting the position of the movable filter plate 5, the second filter hole 14 and the first filter hole 13 can be partially or completely overlapped, thereby changing the size of the filter hole diameter. Furthermore, the operator rotates the rotating rod at the top of the threaded top screw 16 on the top surface of the sleeve box 7, so that the rubber anti-slip soft layer fixedly connected to the bottom end of the top screw 16 tightly presses against the push plate 6, thereby better fixing the push plate 6; Next, the pearls that need to be sorted are poured into the first filter box 2, and the conveyor 1 starts to run. The pearls sorted in the first filter box 2 fall onto the surface of the conveyor belt of the conveyor 1. After being transported by the conveyor 1, they fall into the second filter box 3. After being filtered by the second filter box 3, they fall into the collection box below the second filter box 3. The second filter box 3 and the first filter box 2 are both fixedly connected to a baffle by bolts on one side. The baffle is removed, and the pearls on the fixed filter plate 4 can be easily taken out. Furthermore, during the filtration process, the actuating plate 11 can be moved as needed to improve filtration efficiency. The first guide mechanism 8 and the second guide mechanism 9 start working. When the servo motor 92 in the second guide mechanism 9 starts and drives the lead screw 93 to rotate, it will drive the sleeve block 17 and the moving plate 10 to move laterally. When the lead screw 93 in the first guide mechanism 8 rotates, it drives the combination of the moving plate 10 and the actuating plate 11 to move back and forth. The actuating plate 11 is fixedly connected to the bottom surface of the moving plate 10. A silicone soft layer is fixedly connected to the outer surface of the actuating plate 11 to avoid damaging the pearl.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
