Description

Technical Field

[0001] This utility model relates to the field of color sorters, and in particular to a color sorter for food processing. Background Technology

[0002] A color sorter is a device that automatically sorts discolored particles from granular materials by utilizing differences in the optical properties of the materials and employing photoelectric detection technology. During operation, the material to be sorted enters from the hopper at the top of the machine. Vibration from a vibrator causes it to slide down a channel and accelerate into the observation area of ​​the sorting chamber, subsequently passing through the area between the sensor and the background plate. Under illumination, the system generates an output signal based on the intensity and color changes of the light, driving a solenoid valve to blow discolored particles into the waste chamber of the receiving hopper, while qualified material continues to fall into the finished product chamber of the receiving hopper, thus achieving the sorting purpose.

[0003] In actual grain color sorting processes, when the grain is fed too quickly, the color sorter may be unable to identify and separate impurities or substandard grain particles in a timely and accurate manner. This can lead to defects and omissions in the color sorting process, affecting not only the efficiency of the color sorter but also potentially negatively impacting the overall quality of the grain.

[0004] To address color sorting issues caused by excessively rapid feeding, sometimes the feed inlet is set to a smaller outlet. However, this approach can introduce new problems, namely feed inlet clogging. When the feed inlet size decreases, the flow resistance of the grain particles increases, making clogging more likely if the grain's moisture content, viscosity, or particle size distribution is uneven. This not only affects the color sorter's continuous operating capacity but can also increase maintenance costs and downtime. Utility Model Content

[0005] The main objective of this invention is to provide a color sorter for food processing, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A color sorter for food processing includes a base frame, a color sorting box, and a feeding box. The color sorting box is mounted on the base frame, and the feeding box is located at the top rear end of the color sorting box. Grain is fed into the color sorting box through the feeding box for color sorting.

[0008] The upper end of the feeding box is provided with a feeding hopper, and the feeding hopper is provided with two connecting rollers of different heights. The two connecting rollers are inserted into the feeding box and the two ends are connected with bearing assemblies. A first stirring material release device and a second stirring material release device are respectively installed on the two connecting rollers. The first stirring material release device and the second stirring material release device realize the slow release of grain.

[0009] The outer ends of the two connecting rollers are respectively connected to a first transmission gear and a second transmission gear, which are meshed together. The outer end of the first transmission gear is connected to an input connecting rod, which is connected to the drive motor to realize power input.

[0010] In an optional embodiment of this application, a support frame is installed at the upper end of the base frame. The support frame wraps around the color sorting box and is fixed to the color sorting box by bolts and anti-slip strips. The support frame covers the connection between the color sorting box and the feeding box to provide protection. The connection is sealed with an adhesive strip.

[0011] In an optional embodiment of this application, the bearing assembly is fixed to the feed box by bolts, there is a gap between the bearing assembly and the first transmission gear and the second transmission gear, the input connecting rod is fixedly connected to the first transmission gear, and the input connecting rod passes through the first transmission gear and is fixed to the connecting roller by bolts and nuts;

[0012] In an optional embodiment of this application, a plurality of first stirring material releasers are equidistantly distributed on the connecting roller, and the outer wall of the first stirring material releaser is provided with a plurality of arc-shaped strips, which are distributed in a ring on the body of the first stirring material releaser. The structures of the first stirring material releaser and the second stirring material releaser are identical.

[0013] In an alternative embodiment of this application, a plurality of the first stirring material releasers are equidistantly distributed on a connecting roller, and a plurality of the second stirring material releasers are equidistantly distributed on another connecting roller;

[0014] In an optional embodiment of this application, the notches of the first stirring material releaser and the second stirring material releaser are designed to be staggered. The second stirring material releaser is located at the outlet of the feed hopper, which promotes the movement of grain at the outlet of the feed hopper and prevents blockage.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By using a first agitator and a second agitator installed on two connecting rollers at different heights, the grain is released slowly and evenly. This design avoids blockage and accumulation of grain during the feeding process, ensuring that the grain can smoothly enter the color sorting box for color sorting.

[0017] The notches of the first and second agitator-type material releasers are staggered, with the second agitator-type material releaser located at the outlet of the feed hopper. This design effectively promotes grain movement at the feed hopper outlet, further preventing grain blockage and improving the smoothness and efficiency of grain entering the color sorting box.

[0018] Multiple primary and secondary agitator material releasers are equidistantly distributed on the connecting roller, ensuring uniform release and dispersion of material within the color sorting chamber. This distribution improves the efficiency and accuracy of color sorting, enabling the color sorter to better identify and separate grains of different colors or qualities.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 - Figure 4 As shown, a color sorter for food processing consists of a base frame 1, a color sorting box 3, and a feeding box 4. The color sorting box 3 is mounted on top of the base frame 1, while the feeding box 4 is located at the top rear end of the color sorting box 3. Through the feeding box 4, grains can be smoothly fed into the color sorting box 3 for efficient color sorting.

[0026] The upper part of the feeding box 4 is designed with a feeding hopper 5, and the feeding hopper 5 is equipped with two connecting rollers 6 of different heights. These two connecting rollers 6 pass through both ends of the feeding box 4 and are connected to the bearing assembly 9. A first stirring material release device 7 and a second stirring material release device 8 are respectively installed on the connecting rollers 6. They work together to achieve slow and uniform release of grain.

[0027] The outer ends of the connecting roller 6 are connected to the first transmission gear 10 and the second transmission gear 12, respectively, and these two transmission gears mesh with each other for transmission. The outer end of the first transmission gear 10 is connected to an input connecting rod 11, which is connected to the drive motor to realize the input of power and ensure the smooth operation of the entire color sorting process.

[0028] A support frame 2 is installed on the upper part of the base frame 1. The support frame 2 surrounds and wraps around the color sorting box 3, and is firmly fixed to the color sorting box 3 with bolts and anti-slip strips. The support frame 2 not only covers the connection between the color sorting box 3 and the feed box 4, but also provides protection. In addition, the connection is sealed with an adhesive strip to ensure the airtightness and stability of the equipment.

[0029] The bearing assembly 9 is fixed to the feed box 4 by bolts, and an appropriate gap is left between the bearing assembly 9 and the first transmission gear 10 and the second transmission gear 12. The input connecting rod 11 is fixedly connected to the first transmission gear 10, passes through the first transmission gear 10, and is fixed to the connecting roller 6 by bolts and nuts. This design ensures the accuracy and reliability of the transmission.

[0030] Multiple first-stage stirring material releasers 7 are equidistantly distributed on the connecting roller 6, and each first-stage stirring material releaser 7 has multiple arc-shaped strips on its outer wall. These arc-shaped strips are distributed in a ring on the main body of the first-stage stirring material releaser 7, forming a unique structure. The structural design of the first-stage stirring material releaser 7 and the second-stage stirring material releaser 8 is consistent, which ensures their synchronicity and coordination during operation;

[0031] Multiple first-stage agitator material releasers 7 are equidistantly distributed on a connecting roller 6, while multiple second-stage agitator material releasers 8 are equidistantly distributed on another connecting roller 6. This distribution method ensures uniform release and dispersion of material within the color sorting box 3, thereby improving the efficiency and accuracy of color sorting.

[0032] The notches of the first agitator material releaser 7 and the second agitator material releaser 8 are staggered, with the second agitator material releaser 8 located at the outlet of the feed hopper 5. This design effectively promotes the movement of grain at the outlet of the feed hopper 5, prevents grain blockage, and ensures that the grain smoothly enters the color sorting box 3, thereby improving the efficiency and reliability of the entire color sorting process.

[0033] Ensure the color sorter is correctly installed on the base frame 1, and that the color sorting box 3 and the feed box 4 are correctly connected. Check that all bolts and anti-slip strips are secure, and ensure a good seal at the connection between the color sorting box 3 and the feed box 4. Confirm that the support frame 2 is wrapped around the color sorting box 3 and securely fixed to it with bolts and anti-slip strips. Check that the bearing assembly 9 is bolted to the feed box 4, and ensure that there is an appropriate gap between it and the drive gear.

[0034] Turn on the drive motor, causing the input connecting rod 11 to rotate the first transmission gear 10. Since the first transmission gear 10 and the second transmission gear 12 mesh with each other, the second transmission gear 12 will also rotate. The connecting roller 6, connected to the transmission gears, begins to rotate, driving the first stirring material releaser 7 and the second stirring material releaser 8 to work. Grain is poured into the feed hopper 5. The grain passes through the feed hopper 5 into the first stirring material releaser 7 and the second stirring material releaser 8 on the connecting roller 6. The staggered notches of the first stirring material releaser 7 and the second stirring material releaser 8 promote the even release and dispersion of the grain.

[0035] The grain undergoes efficient color sorting within the color sorting chamber 3. The color sorter uses optical sensors to identify and separate grains of different colors or qualities. The sorted grain is discharged from the outlet of the color sorting chamber 3, completing the entire color sorting process. During the color sorting process, the equipment operation is checked regularly to ensure there are no blockages or abnormal noises. After the color sorting task is completed, the drive motor is turned off, and any residual grain in the feed hopper 5 and color sorting chamber 3 is cleaned. The bearing assembly 9 and transmission gears are regularly inspected and maintained to ensure long-term stable operation of the equipment.
