Description
Technical Field
[0001] This utility model belongs to the field of color sorter technology, specifically relating to a uniform feeding device for a color sorter. Background Technology
[0002] Color sorters are key equipment in the field of material sorting and are widely used for quality screening of raw materials such as grains, plastic granules, and ores. Their core working efficiency is closely related to the uniformity and cleanliness of the feeding process.
[0003] In practical applications of existing color sorter feeding devices, there are certain shortcomings: First, raw materials (such as grains in humid environments and easily agglomerated plastic granules) are easily affected by humidity and pressure during storage or transportation, causing them to stick together and clump. After being poured into the feeding device, they can easily cause blockage of the feed inlet or lead to uneven falling speed of the raw materials, resulting in an imbalance in the distribution of raw materials in the sorting channel of the color sorter, directly reducing the color sorting accuracy, and even causing frequent equipment shutdowns for cleaning. Second, a large amount of dust is generated during the pouring process of raw materials. Existing feeding devices mostly lack efficient integrated dust removal mechanisms. The dust diffuses into the workshop environment, not only polluting the production site, but may also be inhaled by operators, endangering their health. Utility Model Content
[0004] The purpose of this utility model is to provide a uniform feeding device for a color sorter, so as to solve the problems mentioned in the background art, that the feeding devices of some existing color sorters cannot break up the raw materials, the sticky raw materials are prone to blockage of the feed inlet, or cause uneven falling speed of the raw materials, and that existing feeding devices mostly lack an efficient integrated dust removal mechanism.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a uniform feeding device for a color sorter, comprising a feeding box and a guide sleeve fixed to the top of the feeding box. A drive motor is installed on one outer wall of the feeding box, and a drive shaft is fixed to the output end of the drive motor. Multiple conveying blades are fixed to the outer wall of the drive shaft. A rotary motor is installed on one outer wall of the guide sleeve, and a protective shell is fixed inside the guide sleeve. A rotating shaft is rotatably connected inside the protective shell. Multiple dispersing rods are fixed to the outer walls of the rotating shaft. A feeding hopper is fixed to the top of the guide sleeve, and a dust removal structure is installed on the feeding hopper. An installation box is fixed to the back of the feeding hopper, and movable grooves are opened on both outer walls of the feeding hopper. Dustproof plates are movably connected in the movable grooves.
[0006] In a further embodiment, the output end of the rotary motor is fixed with a rotating shaft extending into the protective housing, the outer wall of the rotating shaft is fixed with a driving bevel gear, and the bottom of the rotating shaft is fixed with a driven bevel gear that meshes with the driving bevel gear.
[0007] In a further embodiment, the dust removal structure consists of a dust removal box, a suction fan, and a suction hood. The dust removal box is fixed to the outer wall of the feed hopper, the suction fan is fixed to the outer wall of the dust removal box, and the suction hood is fixed to the inner wall of the feed hopper. A ventilation pipe is installed between the dust removal box and the suction hood.
[0008] In a further embodiment, a sealing groove is provided on the top of the dust collection box, a sealing plate is installed in the sealing groove, a filter plate is installed at the bottom of the sealing plate, and the suction pipe of the suction fan extends into the dust collection box.
[0009] In a further embodiment, a stepper motor is installed on one inner wall of the mounting box, and a guide post is fixed to the output end of the stepper motor. The outer wall of the guide post is provided with two sets of threaded grooves with opposite directions.
[0010] In a further embodiment, the two sets of threaded grooves on the outer wall of the guide column are each threadedly connected to a guide block that is fixedly connected to the dustproof plate, and a guide groove for the guide block to move is provided on the back of the feed hopper.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] This color sorter's uniform feeding device uses a rotary motor to drive a rotating shaft. The meshing of the active and driven bevel gears drives the rotating shaft and multiple dispersing rods within the protective housing to rotate at high speed. This fully covers the material falling area within the guide sleeve, efficiently breaking up clumps of material and preventing material agglomeration that could cause blockages or uneven flow rates. This lays a uniform foundation for subsequent feeding stages. Simultaneously, a drive motor inside the feeding box drives the drive shaft and conveyor blades to rotate. The conveyor blades stably transport the material along the cylindrical inner wall of the feeding box, preventing material accumulation and further ensuring uniformity of material supply to subsequent processes, significantly improving color sorting accuracy and sorting efficiency.
[0013] The dust removal structure creates negative pressure within the dust collection chamber using a suction fan. Combined with the suction hood on the inner wall of the feed hopper, it can adsorb dust generated during the pouring and falling of raw materials in real time. After entering the dust collection chamber through the ventilation pipe, the dust is trapped by the filter plate, effectively preventing dust from spreading to the working environment and protecting the health of operators. Furthermore, the sealing plate and filter plate in the sealing groove at the top of the dust collection chamber are designed to be detachable, facilitating regular disassembly, cleaning, or replacement of the filter plate to maintain a long-term stable dust removal effect. In addition, a stepper motor drives the guide column to rotate, and the guide block and dustproof plate automatically open and close through the reverse thread groove on the outer wall of the guide column, eliminating the need for manual operation. This not only improves the convenience of feeding but also allows for quick closure of the feed hopper after feeding, blocking the dust leakage path and further enhancing the dustproof effect. The color sorter's uniform feeding device can prevent raw materials from sticking together, thus ensuring uniform feeding and also has a dustproof function, guaranteeing a clean working environment.

[0032] Working principle:
[0033] The uniform feeding device for the color sorter is installed in a suitable position on the color sorter. After the device is started, the stepper motor 20 in the mounting box 19 is controlled to run. The stepper motor 20 drives the guide column 21 at the output end to rotate. Since the outer wall of the guide column 21 has two sets of threaded grooves with opposite directions, the guide block 22, which is threadedly connected to the threaded groove, will move in the opposite direction along the guide groove on the back of the feed hopper 13 and the through groove of the mounting box 19. This will drive the dustproof plates 23 in the moving grooves on both sides of the feed hopper 13 to open synchronously. Then, the raw material to be processed is poured into the feed hopper 13. At the same time, the suction fan 17 in the dust removal structure is started. The operation of the suction fan 17 creates a negative pressure inside the dust removal box 14. Under the action of negative pressure, the dust generated by the raw material in the feed hopper 13 enters the ventilation pipe through the suction hood 18 on the inner wall of the feed hopper 13, and is then transported to the dust removal box 14 through the ventilation pipe. The dust is intercepted by the filter plate 16 at the bottom of the sealing plate 15, and the clean air is discharged from the dust removal box 14 through the suction pipe of the suction fan 17.
[0034] After the raw material slides down the inner wall of the feed hopper 13 into the guide sleeve 5, the rotary motor 6 on one side of the guide sleeve 5 starts, driving the rotary shaft 8, whose output end extends into the protective shell 7, to rotate. The driving bevel gear 9 on the outer wall of the rotary shaft 8 rotates accordingly and meshes with the driven bevel gear 11 at the bottom of the rotary shaft 10, thereby driving the rotary shaft 10 and multiple dispersing rods 12 fixed around it to rotate at high speed inside the protective shell 7, fully dispersing the raw material that is still sticky during the fall. The dispersed raw material falls evenly into the feeding box 1. At this time, the drive motor on one side of the feeding box 1 starts to rotate. When motor 2 starts, it drives the drive shaft 3 and multiple conveying blades 4 fixed on the outer wall to rotate. The conveying blades 4 steadily convey the raw materials forward along the cylindrical inner wall of the feeding box 1 and evenly convey them to the subsequent sorting process of the color sorter through the discharge port at the bottom of the feeding box 1. After the raw materials are added, the stepper motor 20 is controlled to rotate in reverse, driving the guide column 21 to rotate in reverse, so that the two sets of guide blocks 22 move towards each other along the guide groove, thereby driving the dustproof plate 23 to close the top opening of the feeding hopper 13 along the moving groove, preventing dust from leaking out of the feeding hopper 13 during the subsequent color sorting process.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
