Description

Technical Field

[0001] This invention relates to the field of color sorter technology, and more particularly to a color sorter slide device. Background Technology

[0002] Color sorters are devices that use photoelectric detection technology to separate granular materials. They are widely used in the fine processing of agricultural products such as grains, seeds, and nuts. During the operation of a color sorter, the material needs to be arranged in a single layer on the slide device and slide at an appropriate speed so that the photoelectric detection system can accurately identify and remove discolored particles.

[0003] As a core component of the color sorter, the width of the chute directly affects the material's sliding behavior and color sorting effect. If the chute is too wide, the material may tip over or pile up within it, disrupting the single-layer arrangement and severely impacting the accuracy of optical recognition. Conversely, if the chute is too narrow, the material may easily become clogged, hindering normal sliding. Because different materials exhibit significant differences in particle size and shape, the chute width needs to be adjusted according to the material's characteristics to achieve the optimal color sorting effect.

[0004] Currently, color sorter slide devices mainly adopt a fixed-width V-shaped chute design, providing operators with multiple slides of different widths to choose from. In the field of parent seed selection and grading, due to the large number of seed types and varieties, and the significant differences in geometric dimensions between different batches of seeds, operators can only adapt to different materials by replacing the entire slide assembly, which is cumbersome, time-consuming, and labor-intensive. Summary of the Invention

[0005] This invention provides a color sorter slide device, which can realize continuous adjustment of the opening and closing angle of the slide. It has a simple structure, is easy to operate, and effectively improves the reliability and sorting accuracy of color sorting operations.

[0006] This invention provides a color sorter slide device, comprising: multiple slide assemblies, which are sequentially hinged along a first direction; each slide assembly includes two hinged slide plates forming a chute for material to slide between them; a drive mechanism disposed on one side of the multiple slide assemblies along the first direction, the drive mechanism having a driving part movable along the first direction, the driving part being connected to the outermost slide plate; and a balancing mechanism disposed at the bottom of the multiple slide assemblies for connecting the multiple slide assemblies to enable the multiple slide assemblies to expand or retract synchronously; wherein, the first direction is perpendicular to the extension direction of the slide assemblies.

[0007] In one possible implementation, the balancing mechanism includes multiple balance plate groups, each of which is connected to two adjacent slide assemblies.

[0008] In one possible implementation, the balance plate assembly includes two connecting plates hinged at the bottom, the tops of which are fixedly connected to the slide plates of two adjacent slide assemblies, and the extending direction of the connecting plates is parallel to the width direction of the slide plates.

[0009] In one possible implementation, an adaptive adjustment system is also included, comprising: a parameter input unit for inputting material type information; and a controller electrically connected to the parameter input unit and the drive mechanism, configured to control the movement distance of the driven part of the drive mechanism according to the material type information.

[0010] In one possible implementation, the adaptive adjustment system further includes an angle detection unit, which is disposed on the slide assembly and electrically connected to the controller. The angle detection unit is used to detect the opening and closing angle of the slide and feed it back to the controller.

[0011] In one possible implementation, the angle detection unit includes at least one of a rotary encoder and a tilt sensor.

[0012] In one possible implementation, the parameter input unit is a barcode scanner or a wireless communication module.

[0013] In one possible implementation, the controller pre-stores data on the correspondence between material types and the opening and closing angles of the target chute.

[0014] In one possible implementation, the slide assembly further includes spacer pads disposed between two adjacent slide plates to define the minimum opening angle of the slide.

[0015] In one possible implementation, two adjacent slide plates are connected by a hinge shaft, and the ends of the slide plates along the width direction are provided with hinge holes that rotatably engage with the hinge shaft.

[0016] In one possible implementation, there are two drive mechanisms, which are respectively located on both sides of the multiple slide assemblies along the first direction.

[0017] In one possible implementation, the drive mechanism includes: a linear drive assembly; and a drive pull plate disposed at the output end of the linear drive assembly, the drive pull plate being connected to the outermost slide plate along a first direction.

[0018] In one possible implementation, the slide assembly further includes an elastic sheet disposed along the extension direction of the slide assembly, with both ends of the elastic sheet connected to two slide plates respectively, and the top of the elastic sheet recessed to form a groove.

[0019] The color sorter slide device provided by this invention, through the movement of the driving part of the drive mechanism along a first direction, directly pulls the outermost slide plate to move, changing the overall width of multiple slide components along the first direction. Due to the hinged constraint relationship between the slide plates, the linear motion of the driving part is converted into the oscillation of the slide plates, thereby changing the opening angle and width of the trough formed between two slide plates. This ensures the accuracy and repeatability of the trough width adjustment. Operators can make fine adjustments according to the actual size of the seeds, keeping the material in a stable single-layer flow state in the trough. This avoids the side-tipping and stacking of seeds caused by wide troughs and the blockage caused by narrow troughs, providing ideal material presentation conditions for the photoelectric detection system. The balancing mechanism realizes the linkage control of multiple slide components. When a slide component expands or retracts under the action of the drive mechanism, the balancing mechanism synchronously transmits this motion to other slide components, ensuring that the opening and closing angles of all troughs are consistent. This avoids the width deviation that may occur due to independent adjustment of each slide, ensuring that the flow conditions of the material on different slides are the same, and improving the sorting consistency and stability of the entire color sorting system. The color sorter slide device provided by this invention can realize continuous adjustment of the opening and closing angle of the slide. It has a simple structure, is easy to operate, and effectively improves the reliability and sorting accuracy of color sorting operations. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0024] The following is combined with Figures 1 to 5 The present invention describes a color sorter slide device, comprising: multiple slide assemblies 1, a drive mechanism 2, and a balancing mechanism 3, wherein: Multiple slide assemblies 1 are sequentially hinged along the first direction X. Each slide assembly 1 includes two hinged slide plates 11, and a chute 12 for material to slide is formed between the two slide plates 11.

[0025] The drive mechanism 2 is disposed on one side of the plurality of slide rail assemblies 1 along the first direction X. The drive mechanism 2 has a driving part that can move along the first direction X, and the driving part is connected to the outermost slide rail piece 11.

[0026] The balancing mechanism 3 is located at the bottom of multiple slide rail assemblies 1 and is used to connect multiple slide rail assemblies 1 so that multiple slide rail assemblies 1 can be expanded or retracted synchronously.

[0027] Wherein, the first direction X is perpendicular to the extension direction of the slide assembly 1.

[0028] In this invention, the driving part of the driving mechanism 2 moves along the first direction X, directly pulling the outermost slide plate 11 to move, changing the overall width of multiple slide assemblies 1 along the first direction X. Due to the hinge constraint relationship between the slide plates 11, the linear motion of the driving part is converted into the swing of the slide plates 11, thereby changing the opening angle and width of the trough 12 formed between the two slide plates 11. This ensures the accuracy and repeatability of the trough 12 width adjustment. The operator can make fine adjustments according to the actual size of the seeds, so that the material maintains a stable single-layer flow state in the trough 12, avoiding the side-tipping and stacking of seeds caused by wide trough 12 and the blockage caused by narrow trough 12, thus providing ideal material presentation conditions for the photoelectric detection system. The balancing mechanism 3 enables the coordinated control of multiple slide rail components 1. When a slide rail component 1 expands or retracts under the action of the drive mechanism 2, the balancing mechanism 3 synchronously transmits this motion to other slide rail components 1, ensuring that the opening and closing angles of all slide rails 12 remain consistent. This avoids width deviations that may occur due to independent adjustment of each slide rail, ensures that the flow conditions of materials on different slide rails are the same, and improves the sorting consistency and stability of the entire color sorting system. The color sorter slide rail device provided by this invention can realize continuous adjustment of the opening and closing angles of the slide rails 12. It has a simple structure, is easy to operate, and effectively improves the reliability and sorting accuracy of color sorting operations.

[0029] Specifically, when the driving part of the drive mechanism 2 moves along the first direction X, the outermost slide plate 11 connected to it moves accordingly. Due to the hinged arrangement between the slide plate assemblies 1, adjacent slide plate assemblies 1 will rotate relative to each other. The balancing mechanism 3 transmits this motion to all slide plate assemblies 1 by connecting the bottom of multiple slide plate assemblies 1, ensuring that the two slide plates 11 in each slide plate assembly 1 are adjusted according to the same angular relationship, so that the width of all slide grooves 12 remains consistent.

[0030] In one specific embodiment, when color sorting of rice with different particle sizes is required, the operator can adjust the width of the chute 12 by adjusting the drive mechanism 2. For fine broken rice, the slide assembly 1 retracts to narrow the chute 12, preventing the broken rice from rolling laterally and affecting the color sorting accuracy; for large, intact rice grains, the slide assembly 1 expands to widen the chute 12, ensuring that the rice grains slide smoothly without clogging. Throughout the adjustment process, the width of all chute 12 remains uniform, ensuring the consistency of the color sorting operation.

[0031] In related technologies, color sorter tracks typically employ a fixed-width V-groove design, or multiple fixed tracks of varying widths are used for switching. In the field of parent seed selection and grading, due to the large variety of seed types and varieties, and significant differences in the geometric dimensions of different processing batches, operators can only adapt to different materials by replacing the entire track assembly 1, which is cumbersome, time-consuming, and labor-intensive. However, in this embodiment of the invention, the coordinated operation of the hinged track assembly 1 and the balancing mechanism 3 achieves continuous adjustment of the groove width 12, allowing a single track device to adapt to materials with various particle sizes. Compared to a fixed-width design, this improves applicability; compared to multiple track switching methods, it simplifies the structure and saves space.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the balancing mechanism 3 includes a plurality of balancing plate groups 31, each balancing plate group 31 being connected to two adjacent slide rail assemblies 1.

[0033] In this invention, the balancing mechanism 3 includes multiple balancing plate groups 31, each of which is connected to two adjacent slide rail assemblies 1. The segmented connection method enables the effective transmission of driving force between the slide rail assemblies 1. When the outermost slide rail assembly 1 is subjected to driving force, the adjacent balancing plate group 31 transmits the motion and force to the next slide rail assembly 1, forming a step-by-step motion chain to ensure that all slide rail assemblies 1 can move synchronously.

[0034] Specifically, each balance plate assembly 31 acts as an independent transmission unit, responsible for connecting only two adjacent slide rail assemblies 1. When the slide rail assembly 1 unfolds or retracts, the balance plate assembly 31 follows the slide rail assembly 1 and transmits this motion to the adjacent slide rail assembly 1. Multiple balance plate assemblies 31 work together to gradually transmit the motion of the outermost slide rail assembly 1 to the innermost one, achieving overall synchronous adjustment.

[0035] like Figure 3 As shown, the balance plate assembly 31 further includes two connecting plates 311 hinged at the bottom. The tops of the two connecting plates 311 are respectively fixedly connected to the slide plates 11 of two adjacent slide assemblies 1. The extending direction of the connecting plates 311 is parallel to the width direction of the slide plates 11.

[0036] In this invention, the balance plate assembly 31 includes two connecting plates 311 hinged at the bottom. The tops of the two connecting plates 311 are respectively fixedly connected to the slide plates 11 of two adjacent slide assemblies 1. The extending direction of the connecting plates 311 is parallel to the width direction of the slide plates 11, forming a transmission mechanism with motion adaptability. The bottom hinge structure allows the two connecting plates 311 to automatically adjust their included angle as the position of the slide assembly 1 changes, maintaining an effective connection with the slide plates 11.

[0037] Specifically, when the slide assembly 1 unfolds, the distance between two adjacent slide assemblies 1 increases, and the included angle between the two connecting plates 311 in the balance plate assembly 31 increases accordingly to adapt to this change; when the slide assembly 1 retracts, the included angle between the connecting plates 311 decreases. The design that the extension direction of the connecting plate 311 is parallel to the width direction of the slide plate 11 ensures that the direction of force transmission is consistent with the direction of movement of the slide plate 11, avoiding interference from the lateral component force generated during transmission to the slide plate 11.

[0038] Optionally, a floating support unit is provided at the bottom of the slide rail assembly 1. This floating support unit supports the bottoms of multiple slide rail assemblies 1. When the opening angle of the slide groove 12 of the slide rail assembly 1 changes, the overall height of the slide rail assembly 1 will fluctuate slightly. The floating support unit supports the fluctuating slide rail assembly 1, ensuring the stability of the slide rail assembly 1 structure. The floating support unit includes a lifting plate extending in a first direction X. A sliding groove is provided at the top of the lifting plate along the first direction X. A sliding block is provided at the bottom of each slide rail assembly 1, slidingly positioned within the sliding groove, thereby effectively supporting the slide rail assembly 1.

[0039] like Figure 1 and Figure 2 As shown, in some embodiments, an adaptive adjustment system 4 is also included. The adaptive adjustment system 4 includes: a parameter input unit 41 for inputting material type information; and a controller 42 electrically connected to the parameter input unit 41 and the drive mechanism 2. The controller 42 is configured to control the movement distance of the drive mechanism 2 driven by the material type information.

[0040] In this invention, after receiving the material type information, the parameter input unit 41 transmits the information to the controller 42. The controller 42's built-in control program retrieves the corresponding chute 12 width parameter based on the material type information, calculates the distance the drive mechanism 2 needs to move, and outputs a control signal to drive the mechanism 2 to perform the corresponding action. The entire adjustment process requires no manual intervention, greatly improving operational efficiency. It can automatically determine the most suitable chute 12 width based on the characteristic parameters of different materials, eliminating the subjectivity and inconsistency of human judgment.

[0041] In one specific embodiment, when the color sorting production line switches from processing mung beans to processing red beans, the operator inputs the variety information of the red beans through the parameter input unit 41. The controller 42 recognizes that red beans have a larger particle size than mung beans and automatically controls the drive mechanism 2 to unfold the slide assembly 1, adjusting the width of the chute 12 to a suitable state for the red beans to slide. After adjustment, the red beans slide smoothly in the chute 12, preventing blockage due to the chute being too narrow or lateral rolling due to the chute being too wide, thus avoiding impact on color sorting accuracy. The adaptive adjustment system 4 automatically adjusts based on accurate information about the material variety, and the adjustment results have good reproducibility and consistency. Compared to manual adjustment, automatic adjustment eliminates the influence of the operator's experience level, improving adjustment accuracy and operational efficiency.

[0042] like Figure 3 As shown, in some embodiments, the adaptive adjustment system 4 further includes an angle detection unit 43, which is disposed on the slide assembly 1 and electrically connected to the controller 42. The angle detection unit 43 is used to detect the opening and closing angle of the slide 12 and feed it back to the controller 42.

[0043] In this invention, the angle detection unit 43 compares the actual opening and closing angle of the slide 12 with the target angle set by the controller 42. When a deviation exists, the controller 42 automatically corrects and adjusts, forming a complete closed-loop control system to ensure precise control of the width of the slide 12. Specifically, the angle detection unit 43 monitors the change in the included angle between the slide plates 11 in real time and transmits the detected angle signal to the controller 42. The controller 42 compares the actual angle with the target angle and calculates the deviation value. When the deviation exceeds the set range, the controller 42 outputs a correction signal to control the drive mechanism 2 to make fine adjustments until the actual angle reaches the target requirement. This feedback control mechanism effectively compensates for errors caused by factors such as clearance and wear in mechanical transmission.

[0044] In this embodiment of the invention, the introduction of the angle detection unit 43 and closed-loop control enables precise control and real-time correction of the opening and closing angle of the slide 12. Compared with open-loop control, closed-loop control can automatically compensate for various error factors, ensuring adjustment accuracy and long-term stability.

[0045] Preferably, the angle detection unit 43 includes at least one of a rotary encoder and a tilt sensor.

[0046] In this invention, the angle detection unit 43 includes at least one of a rotary encoder and a tilt sensor, providing multiple technical solutions for detecting the opening and closing angle of the slide 12. The rotary encoder determines the opening and closing angle of the slide 12 by detecting the rotation angle of the hinge shaft 14 of the slide plate 11, and has the characteristics of high resolution and fast response speed; the tilt sensor calculates the opening and closing angle of the slide 12 by detecting the tilt angle of the slide plate 11 relative to the horizontal plane, and is easy to install and has strong anti-interference ability.

[0047] Specifically, a rotary encoder is mounted on the hinge shaft 14 of the slide plate 11. When the slide plate 11 rotates, the encoder outputs a corresponding pulse signal or digital signal. The controller 42 determines the precise rotation angle by calculating the number of pulses or reading the digital value. An inclination sensor is fixed on the slide plate 11 and uses an internal accelerometer or gyroscope to detect the tilt state of the slide plate 11 and transmits the tilt angle data to the controller 42.

[0048] In some embodiments, the parameter input unit 41 is a barcode scanner or a wireless communication module.

[0049] In this invention, the parameter input unit 41 is a barcode scanner or a wireless communication module, providing a convenient and efficient solution for obtaining material type information. The barcode scanner can quickly read the barcode or QR code information on the material packaging and automatically identify the material type; the wireless communication module can establish a data connection with the production management system, receiving material information from the host computer, thus realizing information management. When a barcode scanner is used as the parameter input unit 41, the operator only needs to scan the identification code on the material packaging, and the scanner can parse the material type, specifications, and other information and transmit it to the controller 42. When a wireless communication module is used, the production management system can send detailed information about the current batch of materials to the color sorter via a wireless network, eliminating the need for manual input.

[0050] In some embodiments, the controller 42 stores pre-stored data on the correspondence between material types and the opening angle of the target chute 12.

[0051] In this invention, the controller 42 searches for the corresponding optimal opening and closing angle parameters of the chute 12 based on the input material type information, realizing data-driven intelligent adjustment. The establishment of a pre-stored database eliminates the need to reset parameters for each adjustment, improving adjustment efficiency and consistency.

[0052] Specifically, the mapping database contains the product codes, material characteristic parameters, and optimal chute 12 opening angles for various materials. When the controller 42 receives material product information, it quickly obtains the optimal chute 12 opening angle value for that material by searching the corresponding record in the database. The parameters in the database have been verified through extensive experiments and optimized through production practice, ensuring the reliability of the adjustment results.

[0053] In one specific embodiment, the database stores optimal chute 12 parameters for dozens of common agricultural products, including rice, wheat, corn, soybeans, and mung beans. When Thai jasmine rice needs to be color-sorted, the controller 42 finds the optimal opening angle of 25 degrees corresponding to Thai jasmine rice in the database and immediately controls the drive mechanism 2 to adjust to that angle. The pre-stored correspondence database is established based on scientific experimental data and production experience, providing optimal chute 12 parameters for each material.

[0054] In some embodiments, the slide assembly 1 further includes a spacer 13 disposed between two adjacent slide pieces 11 to define the minimum opening and closing angle of the slide groove 12.

[0055] In this invention, a spacer 13 is disposed between two adjacent slide plates 11 to limit the minimum opening angle between the two adjacent slide plates 11, providing safety protection for the width adjustment of the chute 12. The spacer 13 prevents the slide plates 11 from excessively retracting, causing the chute 12 to completely close, ensuring that the chute 12 always maintains the minimum passage width, avoiding material blockage and equipment damage. When the slide plates 11 retract to the minimum opening angle, the spacer 13 bears the compressive force of the slide plates 11 and prevents them from continuing to retract. The thickness of the spacer 13 determines the minimum opening angle between the slide plates 11, and the size of the spacer 13 can be determined according to the smallest particle size material to be processed.

[0056] In some embodiments, two adjacent slide plates 11 are connected by a hinge shaft 14, and the end of the slide plate 11 along the width direction is provided with a hinge hole 111 that rotatably engages with the hinge shaft 14.

[0057] In this invention, two adjacent slide plates 11 are connected by a hinge shaft 14. Each slide plate 11 has a hinge hole 111 at its width end, which rotatably engages with the hinge shaft 14, establishing a standardized hinged connection structure. The engagement of the hinge shaft 14 and the hinge hole 111 provides stable rotational support for the slide plate 11, ensuring smooth movement and accurate positioning during adjustment and preventing loosening or jamming. Specifically, the hinge shaft 14 passes through the hinge hole 111 of adjacent slide plates 11, forming a rotating pair connection. The slide plate 11 can rotate freely around the hinge shaft 14, allowing adjustment of the opening angle of the slide groove 12. A suitable clearance is maintained between the hinge hole 111 and the hinge shaft 14, ensuring rotational flexibility while avoiding loosening caused by excessive clearance. The design of the hinge hole 111 at the width end of the slide plate 11 ensures a reasonable rotational axis position and low rotational resistance.

[0058] In some embodiments, there are two drive mechanisms 2, which are respectively disposed on both sides of the plurality of slide rail assemblies 1 along the first direction X.

[0059] In this invention, by setting two driving mechanisms 2 to adjust the two ends of the slide assembly 1 along the first direction X, the dual-side synchronous driving of the slide device is realized, ensuring the uniform distribution of the adjustment force, avoiding the uneven force and deformation problems that may be caused by single-side driving, and improving the adjustment accuracy and system reliability.

[0060] Specifically, the two drive mechanisms 2 work synchronously, driving the outermost slide plates 11 on both sides of the slide device respectively. When the slide assembly 1 needs to be deployed, the two drive mechanisms 2 move outwards simultaneously, causing the slide device to deploy from both ends at the same time; when the slide assembly 1 needs to be retracted, the two drive mechanisms 2 move inwards simultaneously, achieving symmetrical retraction. This dual-side drive method ensures the motion symmetry and force balance of the slide device.

[0061] In one specific embodiment, the total width of the slide rail device of a large color sorter reaches 2 meters, comprising 20 slide rail components 1. When using single-sided drive, the slide rail component 1 furthest from the drive end has poor adjustment accuracy and is prone to torsional deformation. By switching to dual-sided drive, the adjustment force acts simultaneously from both ends, resulting in a smooth adjustment process for the entire slide rail device and consistent adjustment accuracy across all parts, significantly improving the uniformity of the color sorting effect. The dual-drive mechanism 2 halves the transmission distance, reducing the cumulative error of the transmission chain. Dual-sided synchronous drive also eliminates the unbalanced force caused by single-sided drive, improving the adjustment accuracy and service life of the slide rail device.

[0062] like Figure 5 As shown, in some embodiments, the drive mechanism 2 includes: a linear drive assembly 21; and a drive pull plate 22 disposed at the output end of the linear drive assembly 21, wherein the drive pull plate 22 is connected to the outermost slide plate 11 along the first direction X.

[0063] In this invention, the drive mechanism 2 includes a linear drive assembly 21 and a drive pull plate 22. The drive pull plate 22 is located at the output end of the linear drive assembly 21 and connected to the outermost slide plate 11, forming a precise linear drive transmission chain. The linear drive assembly 21 provides stable linear motion power, and the drive pull plate 22 effectively transmits the driving force to the slide plate 11, achieving precise control of the width of the slide groove 12. The linear drive assembly 21 outputs stable linear motion, and the drive pull plate 22 moves with the linear drive assembly 21, driving the outermost slide plate 11 connected to it to move synchronously. The drive pull plate 22 extends along the length direction of the slide plate 11, and the length of the drive pull plate 22 is consistent with the length of the slide plate 11, which can traction the entire outermost slide plate 11, avoiding uneven force on the slide plate 11 and improving the accuracy and reliability of continuous adjustment.

[0064] like Figure 4As shown, in some embodiments, the slide assembly 1 further includes an elastic sheet 15, which is disposed along the extending direction of the slide assembly 1. The two ends of the elastic sheet 15 are respectively connected to two slide pieces 11, and the top of the elastic sheet 15 is recessed to form a groove 12.

[0065] In this invention, the elastic sheet 15 is arranged along the extension direction of the slide assembly 1, with both ends connected to two slide plates 11 respectively, and the top recessed to form a groove 12, which solves the technical problem of easy material jamming in the traditional V-shaped groove 12. The elastic sheet 15 can automatically adjust the shape and width of the groove according to the change of the included angle of the slide plates 11, forming a more adaptable sliding channel.

[0066] Specifically, the elastic plate 15 is made of a material with a certain degree of elasticity. When the slide plate 11 unfolds, the elastic plate 15 is stretched, widening the groove; when the slide plate 11 retracts, the elastic plate 15 rebounds, narrowing the groove. The groove at the top of the elastic plate 15 is arc-shaped, which provides better material adaptability compared to the traditional V-shaped slide groove 12. When materials slide in the arc-shaped groove, the contact area is larger, making it less likely for them to get stuck at the sharp corners of the groove bottom.

[0067] In one specific embodiment, a color sorter frequently encounters the problem of small particles getting stuck at the bottom of the V-shaped chute 12 when processing crushed corn, affecting sorting efficiency. By using an arc-shaped chute 12 formed by an elastic sheet 15, the crushed corn slides smoothly within the chute 12, significantly reducing the jamming phenomenon. The elastic sheet 15 automatically adapts to different chute 12 widths as the included angle of the slide plate 11 is adjusted, eliminating the need for additional adjustment mechanisms and simplifying the system structure.

[0068] The present invention also provides a method for adjusting the slide device of a color sorter, comprising the following steps: S1. Input material type information through parameter input unit 41; S2, Controller 42 retrieves the pre-stored target chute opening and closing angle parameters based on the material type information; S3. Drive mechanism 2 drives slide rail assembly 1 according to the opening and closing angle parameters of target slide rail 12 to adjust the opening and closing angle of slide rail 12; S4. The angle detection unit 43 detects the actual opening and closing angle of the slide 12 and feeds it back to the controller 42. If there is a deviation, it will be corrected and adjusted.

[0069] In this invention, the adjustment method for the color sorter slide device establishes a complete automatic adjustment workflow, including four steps: parameter input, data retrieval, automatic adjustment, and feedback correction, thus realizing intelligent operation of the slide device. This method standardizes and automates the complex adjustment process, greatly simplifying the operation steps and improving adjustment efficiency and accuracy.

[0070] Specifically, the adjustment process first receives material type information through parameter input unit 41, then controller 42 retrieves pre-stored optimal parameters based on the material information, and then controls drive mechanism 2 to execute the adjustment action. Finally, angle detection unit 43 detects the actual result and makes necessary corrections. The entire process forms a closed-loop control to ensure the accuracy of the adjustment result.

[0071] In one specific embodiment, a grain processing plant's color sorting production line needs to process three different materials—rice, wheat, and corn—within a single day. After adopting this adjustment method, each material change only requires scanning the material label, and the system automatically adjusts the width of the chute 12, reducing the adjustment time from 10 minutes to 2 minutes. Adjustment accuracy and consistency are significantly improved, with consistent results across different shifts, thus enhancing product quality stability. The standardized automatic adjustment method eliminates the influence of human factors, ensuring a fast and accurate adjustment process. The closed-loop control mechanism guarantees adjustment accuracy, and the repeatability of the method ensures stable production quality. Compared to manual adjustment, this method significantly improves production efficiency and automation levels.

[0072] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate. The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs.
