Description

Technical Field

[0001] This utility model relates to the field of color sorter technology, and in particular to a color sorter with a direct-connection air supply structure. Background Technology

[0002] A color sorter is a device that uses automated detection and separation technology based on differences in the optical properties of materials to precisely remove discolored, impurities, or substandard particles from a mixture. It is widely used in industries such as grain, food, plastics, minerals, and pharmaceuticals, and is a key piece of equipment for improving material purity and ensuring product quality. In actual operation, the material conveying system of the color sorter allows the material to be sorted to fall evenly through a vibrating feeder and chutes, forming a stable material flow. When the material passes through the detection area, a light source illuminates the material, and a camera captures the optical signal. The control system compares the material's optical signal with a preset standard value to identify discolored particles or impurities. When impurities pass through the rejection area, the control system triggers a high-speed valve, driving a nozzle to spray compressed air, blowing the impurities away from the normal material flow, thus achieving sorting.

[0003] In existing color sorters, the nozzles used to remove discolored particles or impurities are mostly connected to valves via air pipes. Compressed air enters the inlet of a solenoid valve from the air source. When the solenoid valve is energized and opened, the outlet of the solenoid valve directs the airflow through the air pipe to the nozzle, where it instantly sprays air to remove impurities. However, this connection method prolongs the airflow transmission path, as it takes time for the compressed air to travel from the valve opening to the nozzle via the air pipe. This may lead to a prolonged nozzle response time, resulting in rejection failures and affecting the accuracy of the rejection operation. Furthermore, when multiple air pipes are arranged, they occupy space in the color sorter, and splashed material can easily come into contact with the air pipes, accumulating on them and making subsequent cleaning of the color sorter inconvenient. Therefore, this application provides a color sorter with a direct-connection air supply structure to meet this requirement. Utility Model Content

[0004] To address the aforementioned issues, this application provides a color sorter with a direct-connection air supply structure.

[0005] To achieve the above objectives, this application provides the following technical solution: a direct-connection air-supply structure color sorter, including a frame, with a detection channel for material to fall through the inner side of the frame, and multiple nozzles arranged horizontally below the detection channel. Below the nozzles are air passages connected to them, and the air passages have multiple air inlets, each equipped with a valve. The valves are arranged horizontally below the nozzles. Compressed airflow passing through the valves passes through the air passages and is then ejected through the nozzles to the area below the detection channel, thus removing non-compliant materials from the large quantity of material falling through the detection channel.

[0006] Furthermore, a guide plate inclined to the rear is installed at the rear end of the nozzle, and the same mounting seat is provided behind multiple valves, with the guide plate fixed to the mounting seat.

[0007] Furthermore, a receiving support frame is fixed on the mounting base, the receiving support frame is located below the valve, and the air pipe interface of the valve faces the inside of the receiving support frame.

[0008] Furthermore, each of the accommodating support frames has a fixed machine platform at its bottom end. The machine platform is equipped with an air supply device, and the machine platform and the accommodating support frame are connected to the detection channel side by the same sealing baffle. The sealing baffle extends to the front side of the air passage and valve, and is located below the nozzle.

[0009] Furthermore, a vibrating feed hopper is provided at the top of the frame, and the outlet of the vibrating feed hopper corresponds to the detection channel. The material falling through the vibrating feed hopper enters the detection channel and slides down inside the detection channel.

[0010] Furthermore, the inner side of the frame is provided with a first optical detection component and a second optical detection component. The first optical detection component and the second optical detection component are located at the front and rear of the machine respectively. The material slides down inside the detection channel and leaves the detection channel at the end to enter a free fall state. At this time, the first optical detection component and the second optical detection component illuminate the material and capture particle images.

[0011] Furthermore, a receiving hopper is provided in the relative space between the first optical detection component and the machine tool. The receiving hopper is directly opposite the material outlet of the detection channel, and the material falling through the detection channel falls into the receiving hopper.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model can shorten the airflow transmission path, reduce the time required for compressed air to reach the nozzle from the valve opening, and thus reduce the time required for the nozzle to respond, enabling the nozzle to perform the rejection operation in a timely and rapid manner. It can also reduce turbulence and pressure loss generated during airflow transmission, making the airflow pressure reaching the nozzle tend to be stable, effectively avoiding the phenomenon of different jet force of nozzles at different positions, and improving the accuracy of the nozzle rejection operation.

[0014] 2. In the actual installation of the color sorter, this utility model eliminates the need to reserve space for the bending and arrangement of air pipes, effectively solving the problem of bulky internal structure caused by a large number of air pipes, which limits the miniaturization design of the machine. Furthermore, it effectively prevents splashed materials from falling onto the air pipes, reducing the difficulty of cleaning operations and facilitating subsequent cleaning of the color sorter.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Reference Figure 1-4 The color sorter with a direct-connection air supply structure shown includes a frame 1. A detection channel 3 is provided inside the frame 1 for material to fall through. Multiple nozzles 6 are arranged horizontally below the detection channel 3. An air passage 8, connected to the nozzles 6, is located below the nozzles 6. Multiple air inlets are provided on the air passage 8, and each air inlet is equipped with a valve 9, allowing the valves 9 to be arranged horizontally below the nozzles 6. The compressed airflow passing through the valves 9 passes through the air passage 8 and is then ejected through the nozzles 6 to the area below the detection channel 3, removing non-compliant materials from the large quantity of material falling through the detection channel 3.

[0027] In traditional color sorters, valve 9 and nozzle 6 are mostly connected by an air pipe. Compressed air enters the air inlet of valve 9 from the air source. When valve 9 is energized and opened, the air outlet guides the airflow through the air pipe and the air passage 8 into nozzle 6. Nozzle 6 sprays air to remove impurities.

[0028] In this invention, by directly connecting the valve 9 to the air passage 8 below the nozzle 6, the airflow transmission path can be shortened, reducing the time required for compressed air to reach the nozzle 6 when the valve 9 is opened, thereby reducing the time required for the nozzle 6 to respond. For high-speed moving materials, the nozzle 6 can perform a timely and rapid rejection operation.

[0029] At the same time, by shortening the airflow transmission path, turbulence and pressure loss generated during airflow transmission can be reduced, making the airflow pressure reaching the nozzle 6 tend to be stable, effectively avoiding the phenomenon of jet force difference between nozzles 6 at different positions, and improving the accuracy of nozzle 6 rejection operation.

[0030] Furthermore, by shortening the airflow transmission path, compared to traditional tubular connections, issues such as tubing wear and aging, loose connections leading to leaks, and tubing entanglement and interference can be effectively avoided. When a nozzle 6 experiences abnormal airflow, it is unnecessary to check each corresponding tubing for blockages, leaks, or valve malfunctions, reducing maintenance and replacement costs. Moreover, during the actual deployment of the color sorter, no space needs to be reserved for tubing bends and arrangements, effectively solving the problem of bulky internal structures caused by numerous tubing, which limits the miniaturization of the machine design.

[0031] Example 2: Based on Example 1, such as Figure 5-8As shown, a guide plate 61 inclined backward is installed at the rear end of the nozzle 6, and the same mounting base 62 is provided behind multiple valves 9. The guide plate 61 is fixed to the mounting base 62. The guide plate 61 guides the material splashed behind the nozzle 6, allowing the splashed material to fall behind it. Combined with the docking method adopted by the valve 9 and the air passage 8 below the nozzle 6 in Embodiment 1, the splashed material can be effectively prevented from falling onto the air pipe, so as to facilitate centralized cleaning of the splashed material and reduce the difficulty of the cleaning operation.

[0032] To maintain the stability of nozzle 6, in this invention, a receiving support frame 63 is fixed on the mounting base 62. The receiving support frame 63 is located below valve 9, and the air pipe interfaces of valve 9 all face the inner side of the receiving support frame 63. (See [reference]). Figure 8 As shown.

[0033] like Figure 8 As shown, a machine base 64 is fixed to the bottom of the housing support frame 63. An air supply device 10 is installed inside the machine base 64. During actual use of the color sorter, the air supply device 10 is connected to the air pipe interface of valve 9 via a flexible pipeline. The flexible pipeline is located inside the machine base 64 and the housing support frame 63. Furthermore, the machine base 64 and the housing support frame 63 facing the detection channel 3 are connected by the same sealing baffle 65. The sealing baffle 65 extends to the front of the air passage 8 and valve 9, and is located below the nozzle 6. The sealing baffle 65 protects the flexible pipeline and the air supply device 10 from splashed material, facilitating subsequent cleaning operations of the color sorter.

[0034] Example 3: As Figure 1 , Figure 2 As shown, a vibrating feed hopper 2 is located at the top of the frame 1. The outlet of the vibrating feed hopper 2 corresponds to the detection channel 3. The vibrating feed hopper 2 uses high-frequency vibration (usually driven by a vibrating motor) to evenly and loosely "spread" the material and convey it to the inlet of the detection channel 3 at a stable speed. Its core function is to ensure that the material enters the detection channel 3 in a single, non-overlapping, and non-congested manner. The detection channel 3 is usually an inclined metal or wear-resistant plastic slide. The material slides down the detection channel 3 and is released from its constraint at the end of the detection channel 3, entering a free-falling state.

[0035] like Figure 1As shown, a first optical detection component 5 and a second optical detection component 7 are provided inside the frame 1, located at the front and rear of the machine base 64, respectively. The lenses of the first optical detection component 5 and the second optical detection component 7 must be aligned with the free fall area at the end of the detection channel 3 to ensure complete imaging of individual material particles. The material slides down inside the detection channel 3, detaches from the detection channel 3 at the end, and enters a free fall state. At this time, the first optical detection component 5 and the second optical detection component 7 illuminate the material and capture particle images.

[0036] The control system processes the image, extracts the optical features of each particle (such as color value and grayscale value), and compares them with the preset qualification standards (set through the human-machine interface). If the particle features exceed the qualification range (such as discoloration or mold), it is judged as "waste material" and its position and falling time are recorded.

[0037] like Figure 2 As shown, a receiving hopper 4 is provided in the relative space between the first optical detection component 5 and the machine base 64. The receiving hopper 4 is directly opposite the material outlet of the detection channel 3, and the material falling through the detection channel 3 falls into the receiving hopper 4. The receiving hopper 4 is composed of a waste hopper and a finished product hopper. The finished product hopper is the main channel located below the nozzle 6. Qualified materials are not disturbed by the air jet and fall into the finished product hopper along their original trajectory. The waste hopper is located on the side of the finished product channel. When discolored particles fall to the "sorting point" corresponding to the nozzle 6, the control system triggers the corresponding nozzle 6, and a high-speed airflow is instantly ejected, blowing the discolored particles into the waste hopper inside the receiving hopper 4.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
