Description

Technical Field

[0001] The invention belongs to the technical field of tea color sorting, and in particular relates to a machine for sorting light and floating materials in tea leaves. Background Art

[0002] Color sorting is a technology that uses the differences in light intensity and wavelength reflected from the surface of a material, combined with high-precision sensors to capture characteristic information, identify discolored particles through image processing algorithms, and trigger a sorting device to remove them. In the tea production process, color sorting of tea is a crucial step in ensuring tea quality.

[0003] With the continuous improvement of color sorting technology, the color sorting output of tea machines is gradually increasing, and customers' requirements for tea quality are also constantly improving. However, the existing color sorters on the market are not very effective in removing light impurities (hair, dust, etc.) and cannot fully meet customer needs. Therefore, there is an urgent need for a new and quality-guaranteed light impurity sorting machine for tea. Summary of the Invention

[0004] The purpose of the present invention is to provide a machine for sorting light-weight materials in tea leaves in response to the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a light-leaf tea material sorting machine, comprising:

[0006] A color sorting component includes a workbench, a conveyor belt is provided above the workbench, the conveyor belt is driven by a drive motor, a sorting box and a receiving hopper are provided at the output end of the conveyor belt, and the sorting box is located above the receiving hopper.

[0007] Furthermore, a support plate is fixed above the conveyor belt, the drive motor is fixed to the upper surface of the support plate, and the output shaft of the drive motor is connected to the drive shaft of the conveyor belt through a pulley and a belt transmission.

[0008] Furthermore, a scraping assembly is provided on the support plate, and the scraping assembly includes a screw threadedly connected to the middle of the support plate, the screw passes through the support plate, a handle is fixed on the top of the screw, and a scraping plate is provided at the bottom of the screw.

[0009] Furthermore, three fixed blocks are fixed above the scraper plate, the bottom end of the screw is rotatably connected to the middle fixed block, sleeves are fixed on the two fixed blocks on both sides, a sliding rod is slidably fitted in the sleeve, and the top end of the sliding rod is fixed to the lower surface of the support plate.

[0010] Furthermore, an adsorption component is provided on the conveyor belt, and the adsorption component includes two symmetrically arranged trapezoidal blocks fixed above the conveyor belt, a rotating shaft is rotatably connected between the two trapezoidal blocks, a partition passing through the rotating shaft is fixed on the rotating shaft, two mounting plates are fixed at both ends of the partition, and two symmetrical electrostatic plates are provided between the two mounting plates.

[0011] Furthermore, the partition is provided with a control component for controlling the power-on state of the electrostatic plate, and the control component includes a slide rail fixed on the partition, a counterweight plate is slidably fitted on the slide rail, a first conductive plate is provided on the counterweight plate, and a second conductive plate is provided on the mounting plate.

[0012] Furthermore, the conveyor belt is provided with a cleaning component for cleaning light materials, the cleaning component includes a support rod fixed on the trapezoidal block, a dust collection head is fixed on the support rod, a support seat is fixed on the support plate, a suction fan is fixed on the support seat, and the air inlet of the suction fan is connected to the dust collection head.

[0014] Compared with the existing technology, the advantages of the present invention are:

[0015] 1. The present invention first absorbs light materials such as dust through an electrostatic plate, and then cleans the electrostatic plate through a suction fan. In the process of processing light materials, the electrostatic plate not only plays a role in transferring light materials, but also has a shielding effect on the dust collector head, avoiding the suction of tea leaves when the dust collector head directly absorbs light materials, thereby reducing the waste of tea leaves.

[0016] 2. The electrostatic plate in the present invention also plays a light-shielding role, preventing the camera from being overexposed due to strong external light, which is beneficial to improving color sorting accuracy.

[0017] 3. The present invention provides a scraping plate to scrape the tea leaves on the conveyor belt flat, so that the tea leaves are evenly spread on the conveyor belt in a single layer, thereby avoiding the tea leaves from stacking on the conveyor belt, thereby avoiding mutual interference between the tea leaves and further improving the color sorting accuracy.

[0018] 4. The scraping plate in the present invention also plays a blocking role. When the sorting box needs temporary adjustment or a minor fault occurs, the scraping plate can be lowered by rotating the handle so that the scraping plate abuts against the conveyor belt. The scraping plate can block the conveyance of tea leaves, so that the sorting box can be debugged or repaired without stopping the machine, which is conducive to improving work efficiency.

[0031] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0032] like Figures 1-8As shown, a light-weight material sorting machine for tea leaves comprises a color sorting component, which comprises a workbench 1. A conveyor belt 11 is provided above the workbench 1. The conveyor belt 11 is driven by a driving motor 14. Specifically, a support plate 111 is fixed above the conveyor belt 11. The driving motor 14 is fixed to the upper surface of the support plate 111. The output shaft of the driving motor 14 is connected to the driving shaft of the conveyor belt 11 through a pulley and a belt transmission. A protective shell is provided on the outer side of the pulley and the belt. The output shaft of the driving motor 14 and the driving shaft of the conveyor belt 11 are both rotatably connected to the protective shell. A sorting box 12 and a receiving hopper 13 are provided at the output end of the conveyor belt 11. The sorting box 12 is located above the receiving hopper 13. After the tea leaves separate from the conveyor belt 11, they fall into the receiving hopper 13 in a parabolic shape. A finished product material port and an impurity material port are provided at the bottom of the receiving hopper 13. The tea leaves are color-sorted through the sorting box 12, and the finished tea leaves fall into the finished product material port, and the impurities fall into the impurity material port.

[0033] The support plate 111 is provided with a scraping assembly, which includes a screw 21 threadedly connected to the middle of the support plate 111. The screw 21 passes through the support plate 111. A handle 22 is fixed to the top of the screw 21. A scraping plate 23 is provided at the bottom of the screw 21. When the tea leaves are transported on the conveyor belt 11, the scraping plate 23 scrapes the tea leaves so that the tea leaves are evenly distributed on the conveyor belt in a single layer, thereby avoiding the tea leaves from stacking together and interfering with each other, thereby improving the color sorting accuracy. Three fixed blocks 24 are fixed above the scraping plate 23. The bottom end of the screw 21 is rotatably connected to the fixed block 24 in the middle, and the two on both sides are connected A sleeve 25 is fixed on the fixed block 24, and a slide rod 26 is slidably fitted in the sleeve 25. The top of the slide rod 26 is fixed to the lower surface of the support plate 111. During operation, the height of the scraping plate 23 can be adjusted by rotating the handle 22 to drive the screw 21 to rotate. It is suitable for scraping different types of tea leaves and has a wide range of applications. In addition, when the sorting box 12 needs to be debugged or a minor fault occurs, the scraping plate 23 can be lowered so that the scraping plate 23 abuts against the conveyor belt 11. The scraping plate 23 can block the transportation of the tea leaves, so that the sorting box 12 can be debugged or repaired without stopping the machine.

[0034] The conveyor belt 11 is provided with an adsorption assembly, which includes two symmetrically arranged trapezoidal blocks 31 fixed above the conveyor belt 11. A rotating shaft 32 is rotatably connected between the two trapezoidal blocks 31. The rotating shaft 32 is driven by existing technology, such as by a hydraulic telescopic rod in conjunction with a gear and a rack to drive the rotating shaft 32 to rotate intermittently, or by a grooved wheel mechanism between the rotating shaft 32 and the driving shaft of the conveyor belt 11 to drive the rotating shaft 32 to rotate intermittently (the specific driving method of the rotating shaft is not shown in the figure). A partition 33 that passes through the rotating shaft 32 is fixed on the rotating shaft 32. When the rotating shaft 32 is stationary, the partition 33 is in an inclined state. Figure 2As shown in , the rotating shaft 32 rotates 180° each time when it rotates intermittently. Two mounting plates 34 are fixed at both ends of the partition 33. Two symmetrical electrostatic plates 35 are provided between the two mounting plates 34. The surface of the electrostatic plate 35 is provided with multiple rubber strips to prevent the light substances adsorbed thereon from sliding off when the electrostatic plate 35 is powered off. A control component for controlling the power state of the electrostatic plate 35 is provided on the partition 33. The control component includes a slide rail 36 fixed to the partition 33. A counterweight plate 37 is slidably fitted on the slide rail 36. The counterweight plate 37 is provided with a first conductive sheet 371. A second conductive sheet 38 is provided on the mounting plate 34. The first conductive sheet 371 and the second conductive sheet 38 on the same side of the partition 33 are electrically connected to the electrostatic plate 35.

[0035] During operation, the counterweight plate 37 below the partition 33 slides down along the slide rail 36 under the action of gravity, so that the first conductive sheet 371 below the partition 33 is connected to the second conductive sheet 38, and the electrostatic plate 35 below the partition 33 is energized. After the tea leaves are separated from the conveyor belt 11, the dust, hair and other light substances in the tea leaves are adsorbed by the electrostatic plate 35. When the rotating shaft 32 rotates, the partition 33 and the electrostatic plate 35 are driven to rotate synchronously. When the rotating shaft 32 rotates, the counterweight plate 37 moves away from the rotating shaft 32 under the action of centrifugal force. When the rotating shaft 32 rotates, the two first conductive sheets 371 are connected to the corresponding second conductive sheets 38, so that both electrostatic plates 35 are in an energized state, thereby avoiding the situation where the adsorption effect is poor due to an improper angle when the electrostatic plates 35 rotate. When the rotating shaft 32 stops rotating again, the counterweight plate 37 slides down along the slide rail 36 under the action of gravity, so that the first conductive sheet 371 and the second conductive sheet 38 above the partition 33 are separated, thereby disconnecting the electrostatic plate 35 above the partition 33;

[0036] The conveyor belt 11 is provided with a cleaning assembly for cleaning light materials. The cleaning assembly includes a support rod 41 fixed to the trapezoidal block 31, a dust collection head 42 is fixed to the support rod 41, a support base 43 is fixed to the support plate 111, a suction fan 44 is fixed to the support base 43, an air inlet of the suction fan 44 is connected to the dust collection head 42, a storage ball 45 is provided between the suction fan 44 and the dust collection head 42, two ends of the storage ball 45 are respectively connected to the dust collection head 42 and the suction fan 44, a filter plate 46 is provided in the storage ball 45, and a cleaning port 47 is provided on the top of the storage ball 45;

[0037] During specific operation, the suction fan 44 generates suction so that the dust collector head 42 cleans the electrostatic plate 35 above the partition 33, and sucks dust, hair and other light substances on the electrostatic plate 35 above the partition 33 into the storage ball 45. The filter plate 46 filters the light substances to prevent them from entering the interior of the suction fan 44. When the color sorting work is completed, the end cover at the cleaning port 47 is opened to remove the light substances from the storage ball 45.

[0038] The working principle of the present invention is as follows:

[0039] During operation, the height of the scraping plate 23 is adjusted according to the type of tea to be selected. During adjustment, the handle 22 is rotated to drive the screw 21 to rotate, thereby driving the scraping plate 23 to move upward or downward under the action of the threaded fit. The scraping plate 23 is adjusted to an appropriate height so that the tea leaves pass through the bottom of the scraping plate 23 and are evenly spread on the conveyor belt 11 in a single layer, thereby preventing the tea leaves from stacking and interfering with each other, thereby improving the color sorting accuracy.

[0040] The tea leaves to be selected are placed on the conveyor belt 11, the device is powered on and the drive motor 14 is turned on. The drive motor 14 drives the conveyor belt 11 to move and transport the tea leaves to the output end of the conveyor belt 11. After the tea leaves are separated from the output end of the conveyor belt 11, they fall in a parabola. The sorting box 12 performs color sorting on the falling tea leaves. The tea leaves with good quality naturally fall along the parabola into the finished product outlet at the bottom of the receiving hopper 13. The impurities are blown out of the impurity outlet at the bottom of the receiving hopper 13 by the spray valve of the sorting box 12.

[0041] After the tea leaves are separated from the output end of the conveyor belt 11, the tea leaves are separated from the dust or hair because the density of the tea leaves is greater than that of the dust or hair, and the dust or hair is located above the tea leaves. Since the rotating shaft 32 is in a stationary state, the first conductive sheet 371 and the second conductive sheet below the partition 33 are in a connected state. Therefore, when the device is powered on, the electrostatic plate 35 below the partition 33 is simultaneously powered on. After being powered on, the electrostatic plate 35 has an adsorption effect on the dust and hair, adsorbing the dust or hair on the electrostatic plate 35, preventing the dust and hair from entering the receiving hopper 13, thereby improving the quality of the finished product.

[0042] When the rotating shaft 32 begins to rotate under the drive of the driving device, the two counterweight plates 37 move away from the rotating shaft 32 under the action of centrifugal force, so that the two first conductive plates are connected to the corresponding second conductive plates 38, thereby keeping both electrostatic plates 35 in an energized state. This prevents the adsorption effect from being reduced due to improper angles when the electrostatic plates 35 rotate. It also prevents dust and other light objects from sliding off due to power failure when the electrostatic plates 35 below the partition 33 rotate to the upper side. When the rotating shaft 32 rotates 180 degrees and stops rotating again, the counterweight plates 37 slide down along the slide rails 36 under the action of gravity, separating the first conductive plate 371 and the second conductive plate 38 above the partition 33. The electrostatic plate 35 above the partition 33 is de-energized, while the first conductive plate 371 below the partition 33 remains connected to the corresponding second conductive plate 38, allowing the electrostatic plate 35 below the partition 33 to continue to adsorb dust and hair. In addition, the electrostatic plates 35 also serve as light shielding, preventing strong external light from overexposure to the camera, further improving color sorting accuracy.

[0043] When the device is powered on, the suction fan 44 is powered on synchronously. The suction fan 44 generates suction so that the dust collection head 42 cleans the electrostatic plate 35 above the partition 33, and sucks the light matter such as hair adsorbed on the electrostatic plate 35 above the partition 33 into the storage ball 45. The filter plate 46 has a filtering effect on the light matter, preventing the light matter from entering the suction fan 44 and affecting the service life of the suction fan 44. The present invention first adsorbs light matter such as dust through the electrostatic plate 35, and then cleans the electrostatic plate 35 through the suction fan 44 after adsorption. In the process of processing light matter, the electrostatic plate 35 not only plays a role in transferring light matter, but also has a shielding effect on the dust collection head 42, preventing the dust collection head 42 from directly adsorbing light matter and sucking in tea leaves, thereby reducing tea waste.

[0044] When the sorting box 12 needs temporary adjustment or a minor fault occurs, the scraping plate 23 can be lowered by rotating the handle 22 so that the scraping plate 23 abuts against the conveyor belt 11. The scraping plate 23 can block the conveyance of tea leaves, so that the sorting box 12 can be debugged or repaired without stopping the machine.

[0045] After the color sorting work is completed, the device is powered off, the end cover at the cleaning port 47 is opened, and the light objects in the storage balls 45 are centrally cleaned.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
