Description

A color sorter for removing substandard sunflower seeds during processing. Technical Field

[0001] This utility model belongs to the field of sorting technology, specifically relating to a color sorter for removing substandard sunflower seeds. Background Technology

[0002] Color sorters are used in the food and agricultural product processing industries, such as the processing of sunflower seeds, rice, and beans, to accurately remove defective products with abnormal colors, such as discolored, moldy, or spotted particles, ensuring the appearance quality and consistency of products, and improving the overall quality and market competitiveness of products.

[0003] In existing technologies, some color sorters may experience seed accumulation at the feed inlet when processing materials such as sunflower seeds. This is usually due to poor seed flowability or a mismatch between the feeding speed and the processing speed. When sunflower seeds accumulate at the feed inlet, it may affect the feeding efficiency of the color sorter. Although some color sorters are equipped with a continuously rotating mixing plate at the feed inlet to prevent seed accumulation, when too many seeds accumulate and the mixing plate needs to rotate at high speed, it may cause seeds to splatter. This not only wastes materials but may also affect the cleanliness of the working environment and may even cause injury to operators. Summary of the Invention

[0004] The purpose of this invention is to provide a color sorter for removing substandard sunflower seeds, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A color sorter for removing substandard sunflower seeds includes a color sorter body, a frame, a feed inlet fixedly connected to the top of the frame, a chute communicating with the outlet of the feed inlet, an optical detector adapted to be installed on the outside of the chute, an observation window fixedly connected to the inner surface of the feed inlet, and a control panel fixedly installed on the outside of the optical detector.

[0007] The anti-blocking mechanism includes a drive assembly for preventing sunflower seeds from accumulating in the feed inlet, and a clutch assembly for transmitting the rotational power of the drive assembly when the drive assembly rotates too fast, the clutch assembly being located outside the drive assembly.

[0008] The drive assembly includes a servo motor adapted to be installed on the outside of the feed port, a drive rod fixedly connected to the output end of the servo motor via a coupling, and a mixing plate fixedly connected to the outer surface of the drive rod.

[0009] As a preferred embodiment of the present invention, the clutch assembly includes a first belt reel fixedly sleeved on the outer surface of the drive rod, a synchronous belt sleeved on the outer surface of the first belt reel, a second belt reel sleeved on the inner surface of the other end of the synchronous belt, and a transmission column fixedly connected to the outer end face of the second belt reel.

[0010] As a preferred embodiment of the present invention, the clutch assembly further includes a turntable fixedly connected to the outer end face of the transmission column, a plurality of rotating columns fixedly installed on the outer surface of the turntable, a swing block rotatably sleeved on the outer surface of the rotating columns, a friction block fixedly installed on the outside of the swing block, and a tension spring sequentially fixedly connected to the outer surfaces of the plurality of swing blocks.

[0011] In a preferred embodiment of this utility model, the mixing plate is located above the outlet of the feed inlet, and a rotating bearing sleeve is installed at the connection between the drive rod and the feed inlet. A plurality of the rotating columns are arranged in a circumferential array on the outer surface of the turntable.

[0012] When the transmission column drives the turntable to rotate at high speed, it can drive several of the swing blocks to rotate outward around the rotating column simultaneously through centrifugal force.

[0013] As a preferred embodiment of the present invention, the anti-blocking mechanism further includes an anti-splash component for preventing sunflower seeds from splashing when the mixing plate rotates at high speed, and the anti-splash component is disposed on the outside of the swing block.

[0014] As a preferred embodiment of this utility model, the splash-proof assembly includes a force-receiving plate disposed on the outside of the swing block, a rotating rod fixedly installed on the outer surface of the force-receiving plate, and a baffle plate fixedly connected to the outer surface of the rotating rod.

[0015] In a preferred embodiment of this utility model, a rotating bearing sleeve is installed at the connection between the rotating rod and the feed inlet, and the baffle plate is located directly above the mixing plate;

[0016] When several of the aforementioned swing blocks rotate outward around the rotating column simultaneously, they can drive the force-receiving disk, rotating rod, and baffle plate to rotate synchronously through the friction block, thereby causing the baffle plate to block the splashed sunflower seeds by rotating and guide them back into the feed inlet.

[0017] Compared with the prior art, the beneficial effects of this utility model are: through the cooperation of the components in the anti-blocking mechanism, not only can the sunflower seeds gathered in the feed inlet be dispersed in time to ensure smooth feeding, but also when there are too many sunflower seeds and the mixing plate needs to rotate at high speed, the baffle plate can be automatically driven to rotate synchronously to block the splashed sunflower seeds and guide them back into the feed inlet, so as to maintain the stable operation of the color sorter body while avoiding material waste and keeping the environment clean.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example

[0028] Referring to Figures 1 to 4, an embodiment of this utility model is provided, which is a color sorter for removing substandard sunflower seeds, comprising:

[0029] The color sorter body 100 includes a frame 110, a feed inlet 120 fixedly connected to the top of the frame 110, a chute 130 connected to the outlet of the feed inlet 120, an optical detector 140 adapted to be installed on the outside of the chute 130, an observation window 150 fixedly connected to the inner surface of the feed inlet 120, and a control panel 160 fixedly installed on the outside of the optical detector 140.

[0030] It should be noted that the frame 110 is used to support and fix other components in the color sorter body 100, ensuring the stability of the equipment and providing a basic structure for overall operation. The feed inlet 120 is the entrance for sunflower seeds to enter the color sorter body 100, thus providing a material source for the subsequent screening process. The chute 130 is used to guide the sunflower seeds from the feed inlet to the optical detector 140, so that the sunflower seeds can be screened according to the set path, ensuring the smoothness of material transmission. The optical detector 140 uses optical principles to detect the color of sunflower seeds. By identifying the color difference of sunflower seeds, it can be determined whether they are defective products. The optical detector 140 is existing technology, and this solution will not describe it in detail. Moreover, those skilled in the art can clearly understand its working principle. The observation window 150 allows the operator to easily observe the internal condition of the feed inlet 120, such as the feeding status of sunflower seeds, whether there are any abnormalities such as blockages, so as to detect problems in time and deal with them. The control panel 160 is used to control the operating parameters of the color sorter body 100, such as starting and stopping the equipment and adjusting the detection accuracy of the optical detector.

[0031] The anti-blocking mechanism 200 includes a drive assembly 210 for preventing sunflower seeds from accumulating in the feed inlet 120, and a clutch assembly 220 for transmitting the rotational power of the drive assembly 210 when the rotational speed is too fast. The clutch assembly 220 is located outside the drive assembly 210.

[0032] The drive assembly 210 includes a servo motor 211 adapted to be installed on the outside of the feed port 120, a drive rod 212 fixedly connected to the output end of the servo motor 211 via a coupling, and a mixing plate 213 fixedly connected to the outer surface of the drive rod 212.

[0033] It should be noted that the servo motor 211 is used to provide rotational power, drive the drive rod 212 to rotate, and then drive the mixing plate 213 to rotate synchronously. The mixing plate 213 disperses the sunflower seeds gathered in the feed inlet 120 by rotating, preventing them from piling up and ensuring feeding efficiency.

[0034] Specifically, the clutch assembly 220 includes a first belt reel 221 fixedly sleeved on the outer surface of the drive rod 212, a timing belt 222 sleeved on the outer surface of the first belt reel 221, a second belt reel 223 sleeved on the inner surface of the other end of the timing belt 222, and a transmission column 224 fixedly connected to the outer end face of the second belt reel 223.

[0035] Furthermore, the clutch assembly 220 also includes a turntable 225 fixedly connected to the outer end face of the transmission column 224, a plurality of rotating columns 226 fixedly installed on the outer surface of the turntable 225, a swing block 227 rotatably sleeved on the outer surface of the rotating column 226, a friction block 228 fixedly installed on the outside of the swing block 227, and a tension spring 229 sequentially fixedly connected to the outer surface of the plurality of swing blocks 227.

[0036] Preferably, the mixing plate 213 is located above the outlet of the feed inlet 120, and a rotating bearing sleeve is installed at the connection between the drive rod 212 and the feed inlet 120. Several rotating columns 226 are arranged in a circumferential array on the outer surface of the turntable 225.

[0037] When the transmission column 224 drives the turntable 225 to rotate at high speed, it can drive several swing blocks 227 to rotate outward around the rotating column 226 simultaneously through centrifugal force.

[0038] It should be further explained that when the drive rod 212 rotates, it drives the first belt disc 221 to rotate. Through the cooperation of the first belt disc 221 and the synchronous belt 222, it drives the second belt disc 223 to rotate. In turn, the second belt disc 223 drives the transmission column 224 and the turntable 225 to rotate. When the speed of the drive rod 212 is too high, the turntable 225 drives the swing block 227 and the friction block 228 to rotate outward around the rotating column 226 through centrifugal force. At this time, the tension spring 229 is stretched.

[0039] It should be noted that the anti-blocking mechanism 200 also includes an anti-splash component 230 for preventing sunflower seeds from splashing when the mixing plate 213 rotates at high speed. The anti-splash component 230 is located on the outside of the swing block 227.

[0040] Furthermore, the splash guard assembly 230 includes a force-receiving plate 231 located outside the swing block 227, a rotating rod 232 fixedly installed on the outer surface of the force-receiving plate 231, and a baffle plate 233 fixedly connected to the outer surface of the rotating rod 232.

[0041] It should be explained that when the friction block 228 rotates, it can drive the force-receiving disk 231 to rotate synchronously through friction, thereby causing the rotating rod 232 and the baffle plate 233 to rotate synchronously. The baffle plate 233 can block the splashing sunflower seeds by rotating and guide them back to the feed port 120, so as to avoid material waste and prevent the impact on the working environment.

[0042] Specifically, a rotating bearing sleeve is installed at the connection between the rotating rod 232 and the feed inlet 120, and the baffle plate 233 is located directly above the mixing plate 213;

[0043] When several swing blocks 227 rotate outward around the rotating column 226 at the same time, they can drive the force plate 231, the rotating rod 232 and the baffle plate 233 to rotate synchronously through the friction block 228, so that the baffle plate 233 can block the splashed sunflower seeds by rotating and guide them to re-enter the feed inlet 120.

[0044] When in use, start the color sorter through the control panel 160, set the operating parameters such as the detection accuracy of the optical detector 140, and then pour the sunflower seeds to be sorted into the feed inlet 120. The sunflower seeds enter the chute 130 by their own gravity and flow towards the optical detector 140 under the guidance of the chute.

[0045] During this process, the servo motor 211 is powered on and drives the drive rod 212 and the mixing plate 213 to rotate synchronously. The rotation of the mixing plate 213 disperses the gathered sunflower seeds, effectively preventing the sunflower seeds from accumulating in the feed inlet 120 and ensuring smooth feeding. At this time, the drive rod 212 drives the first belt disc 221 to rotate, generating a weak centrifugal force.

[0046] When there are too many sunflower seeds in the feed inlet 120: the speed of the servo motor 211 is increased, causing the drive rod 212 to drive the first belt disc 221 to rotate at high speed, and then the second belt disc 223 is driven to rotate through the synchronous belt 222, which in turn drives the transmission column 224 and the turntable 225 to rotate at high speed. At this time, the turntable 225 generates a strong centrifugal force, which drives the swing block 227 to rotate outward around the rotating column 226. The tension spring 229 is stretched, and the friction block 228 on the outside of the swing block 227 rotates accordingly.

[0047] When the friction block 228 rotates, the friction force drives the force plate 231 to rotate synchronously, which in turn drives the rotating rod 232 and the baffle plate 233 to rotate. The rotation of the baffle plate 233 blocks the sunflower seeds that are splashed due to the high-speed rotation of the mixing plate 213, and guides these sunflower seeds back to the feed inlet 120 to avoid material waste and pollution of the working environment.

[0048] Finally, the sunflower seeds are inspected by an optical detector 140. Substandard sunflower seeds with abnormal color are identified and removed, while qualified sunflower seeds continue to the next step of the process to complete the screening.

[0049] In summary, through the coordinated operation of the components in the anti-blocking mechanism 200, not only can the sunflower seeds gathered in the feed inlet 120 be dispersed in a timely manner to ensure smooth feeding, but also when there are too many sunflower seeds and the mixing plate 213 needs to rotate at high speed, the baffle plate 233 will be automatically driven to rotate synchronously to block the splashing sunflower seeds and guide them back into the feed inlet 120. This achieves the effect of maintaining the stable operation of the color sorter body 100 while avoiding material waste and keeping the environment clean.
