Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a rice processing color sorter. Background Art

[0002] A rice processing color sorter is a machine specifically used for sorting out different-colored particles in rice. Based on the differences in the optical properties of rice, it uses optoelectronic technology and image processing technology to automatically sort out different-colored particles in rice, thereby improving the quality of rice and removing impurities.

[0003] After retrieval, the patent with the publication number CN214132865U discloses a high-efficiency rice processing color sorter. Although the device can drive the rice on the conveyor belt 3 to shake by setting the vibrator 7 during use, so that the dust on the rice can be shaken off, and then under the action of the exhaust fan 13, the moisture and dust in the conveying pipe are sucked into the dust collection box 9, thus avoiding the influence of the dust carried by the rice on color sorting. However, during the use of this device, dust will accumulate on the lens of the optoelectronic detector. The lens is one of the core components of the color sorter, responsible for capturing images of rice and performing precise analysis. Once the lens is covered with dust, it will directly affect the clarity of the image and the accuracy of recognition, thereby reducing the color sorting effect. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a rice processing color sorter, which solves the problems raised in the background art.

[0005] The solution of the utility model to the above technical problems is as follows:

[0006] A rice processing color sorter includes a frame, a screening structure is mounted on the frame, a feed hopper is mounted on the screening structure, and a blanking mechanism is mounted at the bottom end of the frame corresponding to the screening structure.

[0007] The screening structure is provided with a vibration motor, a blanking screen plate is installed on the vibration motor, a guide plate is arranged on one side of the blanking screen plate, a supplementary light lamp and an air distribution block are installed at the bottom end of the guide plate, and a CCD camera module is installed on the frame corresponding to the supplementary light lamp.

[0008] The CCD camera module is provided with a base, a CCD camera body is installed in the base, a fixing seat is installed on the base, and a multi-layer PP film is installed on the fixing seat.

[0009] On the basis of the above technical solutions, the utility model can also be improved as follows.

[0010] Further, the blanking mechanism is provided with a first blanking hopper and a second blanking hopper. The second blanking hopper is used for blanking normal raw materials, and the first blanking hopper is used for blanking the screened raw materials.

[0011] The beneficial effects of adopting the above further scheme are as follows:

[0012] By separately setting the first blanking hopper and the second blanking hopper, the qualified raw materials (normal raw materials) and unqualified raw materials (screened raw materials) can be clearly distinguished, avoiding quality problems that may be caused by mixed blanking. This method of classified collection helps to further process or recycle the unqualified raw materials subsequently, thereby improving the overall product quality. The design of the blanking mechanism makes the screening and classified collection process of raw materials smoother and more efficient. When the CCD camera module identifies unqualified raw materials, the control system can respond quickly and separate them to the first blanking hopper through air flow, while the qualified raw materials continue to fall along the original path to the second blanking hopper. This automated classified blanking method reduces manual intervention and improves production efficiency.

[0013] Further, the air distribution block is evenly provided with nozzles, and the raw materials identified by the CCD camera module are driven to the first blanking hopper for blanking through the air flow blown out by the nozzles of the air distribution block.

[0014] The beneficial effects of adopting the above further scheme are as follows:

[0015] Using air flow instead of mechanical contact to separate discolored or unqualified rice grains avoids mechanical wear and component loss that may be brought about by traditional mechanical separation methods. This non-contact design extends the service life of the equipment and reduces the downtime caused by mechanical failures. The high-precision identification ability of the CCD camera module combined with the evenly distributed nozzles on the air distribution block can ensure the rapid and accurate identification of discolored or unqualified rice grains and separate them from the normal rice flow through air flow. This efficient separation method improves production efficiency and product quality.

[0016] Further, a window is opened at the position corresponding to the CCD camera body on the fixed seat, and the light passes through the PP film and the window and is received and identified by the CCD camera body.

[0017] The beneficial effects of adopting the above further scheme are as follows:

[0018] The PP film acts as a protective barrier, effectively preventing rice grains, dust, or other impurities from directly contacting and contaminating the lens of the CCD camera body. This protection mechanism extends the service life of the camera lens and reduces recognition errors or equipment failures caused by lens contamination. After passing through the PP film and the window, the light can still maintain sufficient clarity and brightness and be accurately received and recognized by the CCD camera body. The PP film has good light transmittance and does not significantly affect the image quality, thus ensuring the accurate recognition of the color, shape, and other characteristics of rice grains by the color sorter. When the PP film is contaminated or worn, its protective performance can be restored through a simple replacement operation. This design makes the cleaning and maintenance of the equipment more convenient and fast, reducing the maintenance cost and time cost.

[0019] Furthermore, a handle is provided on one side of the PP film, and the handles of multiple layers of PP films are distributed in a stepped and staggered manner. The PP film is removed through the handle.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] When the PP film is contaminated or worn, the operator can quickly and conveniently remove it from the fixed seat through the handle. This design greatly simplifies the process of replacing the PP film, reduces the downtime, and improves the maintenance efficiency of the equipment. The fast replacement process means that the equipment can return to the production state faster, thus reducing the production interruption time caused by replacing the PP film. This is of great significance for improving production efficiency and meeting production requirements. Since the replacement process of the PP film is simple and fast, the maintenance cost can be reduced. In addition, the design of multiple layers of PP films also extends the service life of the overall protective layer, further reducing the maintenance cost.

[0022] Furthermore, buckles are provided around the fixed seat, and a slot is opened on the base. The fixed seat is installed on the base through the mutual clamping of the buckles and the slot.

[0023] The beneficial effects of adopting the above further scheme are:

[0024] The design of the buckles and the slot makes the installation process of the fixed seat very simple and fast. The operator only needs to align the buckles of the fixed seat with the slots of the base and then gently snap them in to complete the installation, without the need for additional tools or complex operating steps. Similar to the installation process, the disassembly of the fixed seat is also equally simple. When cleaning, repairing, or replacing the fixed seat is required, the operator can easily separate the fixed seat from the base through the buckles without spending too much time and effort.

[0025] Further, one side surface of the PP film is provided with nano micro suction glue. The PP film is adsorbed and fixed on the fixed seat through the nano micro suction glue, and multiple layers of PP films are adhesively fixed to each other through the nano micro suction glue.

[0026] The beneficial effects of adopting the above further scheme are as follows:

[0027] The nano micro suction glue adopts nano technology and has a strong adsorption capacity. It can ensure that the PP film is tightly adsorbed on the fixed seat, is not easy to fall off or shift, thus ensuring the stability and reliability of the equipment. The nano micro suction glue and the PP film can be reused after being cleaned, which greatly reduces the production cost and material consumption. At the same time, it also reduces the waste generated due to frequent film replacement, which is beneficial to environmental protection and sustainable development. When the PP film is contaminated or worn, due to the adsorption effect of the nano micro suction glue, it can be easily removed from the fixed seat and a new film can be replaced. This design simplifies the replacement process and improves the maintenance efficiency. Both the nano micro suction glue and the PP film have good cleaning performance. During the cleaning process, appropriate cleaning agents and water can be used for cleaning without damaging the film or the adsorption performance of the nano micro suction glue. This design enables the equipment to maintain cleanliness and hygiene, which is beneficial to ensuring product quality and food safety.

[0028] The present utility model provides a rice processing color sorter. It has the following beneficial effects:

[0029] Through the feeding sieve plate driven by a vibration motor, combined with the high-precision recognition of the CCD camera module, unqualified or differently colored rice grains can be quickly and accurately separated from the raw materials. This automated screening process greatly improves the production efficiency and product quality. The first feeding hopper and the second feeding hopper are designed respectively to collect the screened unqualified raw materials and normal raw materials. This design makes the processing process more flexible and facilitates the subsequent further processing or recycling of the unqualified raw materials.

[0030] The CCD camera module is equipped with multiple layers of PP films and nano micro suction glue. These designs not only protect the camera lens from contamination and damage, but also ensure the effective transmission of light and the clear capture of images. The use of nano micro suction glue makes the replacement of the PP film simple and fast, improving the maintenance efficiency and service life of the equipment. The stepped misaligned handle design of the multiple layers of PP films enables the film to be easily removed and replaced with a new film when the film is contaminated, thus maintaining the clear vision and recognition accuracy of the camera. This design greatly reduces the difficulty and cost of cleaning and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Please refer to Figures 1 to 5 shown, the embodiments provided by the present utility model:

[0042] Embodiment 1

[0043] A rice processing color sorter, comprising a frame 3, on which a material screening structure 2 is mounted, on which a feed hopper 1 is mounted, at the bottom of the material screening structure 2 on the frame 3, a blanking mechanism 4 is mounted. The blanking mechanism 4 is provided with a first blanking hopper 401 and a second blanking hopper 402. The second blanking hopper 402 discharges normal raw materials, and the first blanking hopper 401 discharges the screened raw materials. By separately providing the first blanking hopper 401 and the second blanking hopper 402, it is possible to clearly distinguish qualified raw materials from unqualified raw materials, thus effectively avoiding quality problems that may be caused by mixed blanking. This mode of classified collection helps to further process or recycle unqualified raw materials subsequently, thereby improving the overall product quality. The careful design of the blanking mechanism 4 makes the screening and classified collection process of raw materials smoother and more efficient. When the CCD camera module identifies unqualified raw materials, the control system can quickly respond, and separate them to the first blanking hopper 401 by means of air flow, while the qualified raw materials will continue to fall along the original path to the second blanking hopper 402. This automated classified blanking method reduces manual intervention and significantly improves production efficiency. The material screening structure 2 is provided with a vibration motor 204, on which a blanking screen plate 201 is mounted. On one side of the blanking screen plate 201, a guide plate 202 is provided. At the bottom of the guide plate 202, a supplementary light 207 and an air distribution block 206 are mounted. The air distribution block 206 is evenly provided with nozzles 205. The raw materials identified by the CCD camera module 203 are driven by the air flow blown out by the nozzles 205 of the air distribution block 206 to the first blanking hopper 401 for blanking. The use of air flow instead of mechanical contact to separate different-colored or unqualified rice grains avoids mechanical wear and component loss that may be caused by traditional mechanical separation methods. This non-contact design prolongs the service life of the equipment and reduces the downtime caused by mechanical failures. The high-precision recognition ability of the CCD camera module, combined with the evenly distributed nozzles 205 on the air distribution block 206, can ensure the rapid and accurate recognition of different-colored or unqualified rice grains and separate them from the normal rice flow by means of air flow. This efficient separation method not only improves production efficiency but also improves product quality. A CCD camera module 203 is mounted on the frame 3 corresponding to the supplementary light 207.

[0044] Embodiment 2

[0045] For dust-proof protection of the CCD camera module 203, exemplarily, such as Figures 1 to 5As shown in the figure, the present invention further includes: The CCD camera module 203 is provided with a base 2037. Inside the base 2037, a CCD camera body 2032 is installed. On the base 2037, a fixing seat 2036 is installed. There are buckles 2039 around the fixing seat 2036. A card slot 2031 is opened on the base 2037. The fixing seat 2036 is installed on the base 2037 by the mutual clamping of the buckle 2039 and the card slot 2031. The design of the buckle 2039 and the card slot 2031 makes the installation process of the fixing seat 2036 extremely simple and fast. The operator only needs to align the buckle 2039 of the fixing seat 2036 with the card slot 2031 of the base 2037, and then gently snap it in to complete the installation, without the need to use additional tools or complex operating steps. Similar to the installation process, the disassembly of the fixing seat 2036 is also equally simple. When cleaning, repairing or replacing the fixing seat 2036 is required, the operator can easily separate the fixing seat 2036 from the base 2037 through the buckle 2039, without spending too much time and effort. A multi-layer PP film 2034 is installed on the fixing seat 2036. On one side surface of the PP film 2034, nano micro-suction glue 2038 is provided. The PP film 2034 is adsorbed and fixed on the fixing seat 2036 through the nano micro-suction glue 2038, and the multi-layer PP films 2034 are adhesively fixed to each other through the nano micro-suction glue 2038. The nano micro-suction glue 2038 adopts nano technology and has a strong adsorption capacity. It can ensure that the PP film is tightly adsorbed on the fixing seat 2036 and is not easy to fall off or shift, thus ensuring the stability and reliability of the equipment. The nano micro-suction glue 2038 and the PP film can be reused after being cleaned, which greatly reduces the production cost and material consumption. At the same time, it also reduces the waste generated due to frequent film replacement, which is beneficial to environmental protection and sustainable development. When the PP film is contaminated or worn, due to the adsorption of the nano micro-suction glue 2038, it can be easily removed from the fixing seat 2036 and a new film can be replaced. This design simplifies the replacement process and improves the maintenance efficiency. Both the nano micro-suction glue 2038 and the PP film have good cleaning performance. During the cleaning process, appropriate cleaning agents and water can be used for cleaning without damaging the film or the adsorption performance of the nano micro-suction glue 2038. This design enables the equipment to maintain cleanliness and hygiene, which is beneficial to ensuring product quality and food safety. On one side of the PP film 2034, a handle 2035 is provided. The handles 2035 of the multi-layer PP films 2034 are distributed in a stepped and staggered manner. When the PP film 2034 is contaminated, it can be quickly removed through the handle 2035. When the PP film is contaminated or worn, the operator can quickly and conveniently remove it from the fixing seat 2036 through the handle 2035. This design greatly simplifies the process of replacing the PP film, reduces the downtime, and improves the maintenance efficiency of the equipment. The fast replacement process means that the equipment can return to the production state faster, thus reducing the production interruption time caused by replacing the PP film.This is of great significance for improving production efficiency and meeting production requirements. Since the replacement process of the PP film is simple and fast, the maintenance cost can be reduced. In addition, the design of the multi-layer PP film also extends the service life of the overall protective layer, further reducing the maintenance cost. A window 2033 is provided at the position corresponding to the CCD camera body 2032 on the fixing seat 2036. After the light passes through the PP film 2034 and the window 2033, it is received and recognized by the CCD camera body 2032. As a protective barrier, the PP film can effectively prevent rice grains, dust or other impurities from directly contacting and contaminating the lens of the CCD camera body. This protection mechanism extends the service life of the camera lens and reduces the risk of recognition errors or equipment failures caused by lens contamination. After passing through the PP film and the window 2033, the light can still maintain sufficient clarity and brightness and be accurately received and recognized by the CCD camera body. The good light transmittance of the PP film will not have an obvious impact on the image quality, thus ensuring the accurate recognition of the color, shape and other characteristics of rice grains by the color sorter. When the PP film is contaminated or worn, its protective performance can be restored through a simple replacement operation. This design makes the cleaning and maintenance work of the equipment more convenient and efficient, reducing the maintenance cost and time cost.

[0046] Working principle:

[0047] The rice raw materials are put into the feeding hopper 1 and then enter the screening structure 2 by gravity. The vibrating motor 204 in the screening structure 2 drives the feeding sieve plate 201 to vibrate, so that the rice raw materials are evenly distributed on the sieve plate and move forward. During the vibration process, large impurities or foreign objects in the rice raw materials may be preliminarily separated due to gravity, vibration or size differences.

[0048] When the rice raw materials pass through the guide plate 202 of the screening structure 2, the supplementary light lamp 207 provides a stable light source to illuminate the rice grains to be recognized. The CCD camera module 203 is installed on the rack 3 at a position corresponding to the supplementary light lamp 207 and is used to capture the images of the rice grains. The CCD camera body 2032 receives light through the multi-layer PP film 2034 and the window 2033 on the fixing seat 2036 to form clear images. The combination of the multi-layer PP film 2034 and the nano micro-suction glue 2038 protects the camera lens from contamination while allowing light to pass through. The image processing system built in the CCD camera module 203 analyzes the captured images and identifies the discolored or unqualified rice grains.

[0049] Once the discolored or unqualified rice grains are identified, the CCD camera module 203 will send a signal to the control system. The control system controls the nozzles 205 on the air distribution block 206 to eject airflows according to the signal. The airflows act on the discolored or unqualified rice grains and separate them from the normal rice stream. The separated discolored or unqualified rice grains are driven by the airflows to the first hopper 401 for collection. The normal rice grains continue to fall along the original path to the second hopper 402 for collection.

[0050] The foregoing has shown and described the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.

Therefore, it is intended to embrace all changes within the meaning and scope of the equivalent elements of the claims in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed claim.

[0051] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard 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.
