Description

Technical Field

[0001] The present invention relates to the technical field of color sorters, and in particular to a special screening device for color sorters and a system thereof. Background Art

[0002] A color sorter is a device that uses photoelectric detection technology to automatically separate particles of different colors from granular materials based on differences in the materials' optical properties. Color sorters are used for quality inspection and grading of bulk materials, packaged industrial products, and foods. Photoelectric color sorters are non-destructive sorting equipment used for quality inspection and grading of bulk materials. They are widely used in the grain, food, pigment, and chemical industries. They are particularly effective in sorting difficult-to-sort impurities and specialty materials, such as recycled plastic flakes, plastic granules, corn, various beans, various types of rice, minerals, chili peppers, Sichuan peppercorns, garlic, melon seeds, raisins, seeds, traditional Chinese medicine, dried shrimp, dried shrimp, anchovies, glass, metal, and homochromic rods.

[0003] A search revealed a Chinese patent application numbered CN201721774319.5, which discloses a sorting device for a color sorter. The device relates to the technical field of color sorter equipment. It includes a base plate and a feeding device fixed to the base plate.

The sorting device includes symmetrically arranged side panels, a light source, a detector, and a microscope objective lens. The aforementioned sorting device for a color sorter has the following drawbacks:

[0004] Although the overall device can sort the materials, when the materials are fed, they will accumulate and stack in the feed hopper, which may cause the storage hopper to be blocked. Therefore, there is an urgent need for a special screening device and system for color sorting machines. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a special screening device for color sorters and a system thereof.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A special screening device for a color sorter comprises a main body box, a mounting bracket is provided on the outer wall of one side of the back of the main body box, and fixing brackets are provided on the outer walls on both sides of the top of the mounting bracket respectively, a feed hopper is clamped on the top outer wall of the fixing bracket, a material guide assembly is provided in the feed hopper, the bottom outer wall of the feed hopper is provided on the chassis, and an anti-blocking assembly is provided in the chassis, a material guide hole is provided on the top middle outer wall of the mounting bracket, and a material guide channel is provided in the material guide hole, a first collecting hopper and a second collecting hopper are provided on the outer walls of the bottom front and back of the main body box respectively, and one side of the first collecting hopper and the second collecting hopper are connected to a material cover by a hinge, a connecting hole is provided on the outer wall of the top back of the main body box, and the bottom end of the material guide channel is plugged into the connecting hole, and a support plate is provided on the outer wall of the main body box close to the two first collecting hoppers.

[0008] Preferably: the material guide assembly includes a material guide plate, an L-shaped plate, a rotating shaft, a cross plate, a spring column and a transparent guide roller, and the two rotating shafts are respectively rotatably connected to the inner walls on both sides of the feed hopper, and the two cross plates are respectively arranged on the circumference of the two rotating shafts.

[0009] Furthermore, each of the four L-shaped plates is connected to the four corners of each cross plate through spring columns, and a telescopic shaft is provided at the end of each L-shaped plate.

[0010] On the basis of the above solution: each of the material guide plates is respectively arranged at the end of the extension rod of each two opposite telescopic shafts, and the two ends of the transparent guide roller are respectively arranged at the opposite ends of the two rotating shafts.

[0011] A better solution among the above solutions is: the anti-blocking component includes a conveying plate, a slide rail, a limit plate, a motor, a mounting frame, a connecting plate, a guide block, a linkage plate, a guide shaft, a rectangular plate, a connecting shaft and a guide hole, and the chassis contains a driving area and a conveying area.

[0012] As a further solution of the present invention: the slide rail is arranged in the driving area on one side of the chassis, and the top of the linkage plate is slidably connected to the slide rail, the guide block is slidably connected to one side of the linkage plate, the connecting plate is arranged on one side of the guide block, and the conveying plate is arranged on the top of the connecting plate.

[0013] At the same time, the limit plate is arranged on the top of the conveying plate, the motor is fixed to the driving area side of the chassis through the support block, the connecting shaft is arranged at the output end of the motor, and the rectangular plate is arranged at the end of the connecting shaft, and the guide hole is opened on one side of the rectangular plate.

[0014] As a preferred embodiment of the present invention, the installation frame is arranged on the inner wall of the chassis close to the connecting plate, and the guide shaft is slidably connected to the guide hole.

[0015] At the same time, the bottom end of the guide shaft forms a sliding fit with the inner ring of the installation frame, and the guide shaft penetrates the bottom of the connecting plate through a thread.

[0016] A system for a special screening device for a color sorter, comprising the following steps:

[0017] S1: Pour the material into the feed hopper continuously. When the material enters the feed hopper vertically through the conveying equipment, the falling material will be dispersed along the guide plate;

[0018] S2: The guide plate revolves around two rotating shafts, and the transparent guide rollers at the ends of the two rotating shafts cushion the scattered materials and drop them into the conveying area inside the chassis;

[0019] S3: Start the motor, the motor drives the connecting shaft to rotate, the rotating connecting shaft drives the rectangular plate to rotate, and the rotating rectangular plate drives the guide shaft to rotate. During this process, the guide shaft slides in the guide hole in the rectangular plate;

[0020] S4: The bottom end of the guide shaft also slides in the inner ring of the mounting frame, and the rotating guide shaft drives the guide block on one side of the connecting plate to move up and down on the linkage plate. The linkage plate slides horizontally on the slide rail, driving the material on the conveying plate to move up and down and horizontally, and stably delivering the material into the guide channel;

[0021] S5: The materials enter the main box along the material guide channel to perform color sorting of the materials. After the color sorting is completed, the selected materials are poured into the first collection hopper and the second collection hopper respectively.

[0022] The beneficial effects of the present invention are:

[0023] 1. This special screening device and system for a color sorter continuously pours the material into the feed hopper during operation. At this time, the material guiding component in the feed hopper first breaks up the material, thereby ensuring the quality of subsequent color sorting. During the material dredging process, the anti-blocking component is activated to effectively promote the overturning and transportation of the falling material, avoiding the problems of accumulation and stacking of materials during the material guiding process, ensuring the continuity of material feeding and guiding, and improving the efficiency of material color sorting. Then, the material enters the material guiding channel and enters the main box along the material guiding channel for material color sorting. After the color sorting work is completed, the selected materials are poured into the first collection hopper and the second collection hopper respectively.

[0024] 2. This is a special screening device and system for color sorters. When the material enters the feed hopper vertically through the conveying equipment, the falling material will be driven to disperse along the guide plate, and at the same time, the guide plate will revolve around two rotating shafts, thereby effectively promoting the material dispersion effect. During this process, the transparent guide rollers located at the ends of the two rotating shafts can effectively weaken the splashing force of the dispersed material, ensuring the dredging of the material. At the same time, the spring column and telescopic shaft play a role in stabilizing the overall structure.

[0025] 3. A special screening device and system for a color sorter. When the material enters the conveying area in the chassis, the material falls onto the top of the conveying plate. At this time, the motor is started, and the motor drives the connecting shaft to rotate. The rotating connecting shaft drives the rectangular plate to rotate, and the rotating rectangular plate drives the guide shaft to rotate. During this process, the guide shaft slides in the guide hole in the rectangular plate. At the same time, the bottom end of the guide shaft also slides in the inner ring of the mounting frame, and the rotating guide shaft drives the guide block on one side of the connecting plate to rise and fall on the linkage plate. At the same time, the linkage plate slides horizontally on the slide rail, thereby driving the lifting and horizontal movement of the material on the conveying plate, effectively promoting the stable conveying of the material, and allowing the material on the top of the conveying plate to be effectively overturned, avoiding the problem of agglomeration after stacking during the material conveying process, which causes the color sorting quality of the material to decline, improving the looseness of the material conveying, and ensuring the granularity of the internal components of the material, thereby improving the quality of its color sorting.
