Description

Technical Field

[0001] The present invention belongs to the technical field of tea color sorting, and in particular relates to a tea light and floating material sorter. Background Art

[0002] Color sorting is a technology that utilizes the differences in the light intensity and wavelength of the reflected light on the surface of materials, combines high-precision sensors to capture characteristic information, and identifies different-color particles through image processing algorithms and triggers the sorting device to remove them. In the production process of tea, color sorting of tea is a crucial step to ensure the quality of tea.

[0003] With the continuous improvement of color sorting technology, the output of tea color sorting machines is gradually increasing, and customers' requirements for tea quality are also constantly rising. However, the existing color sorting machines on the market currently have poor effects in removing light and floating impurities (such as hair, dust, etc.), and cannot fully meet the needs of customers. Therefore, there is an urgent need for a brand-new tea light and floating material sorter that can ensure quality. Summary of the Invention

[0004] The purpose of the present invention is to address the problems raised in the above background art and provide a tea light and floating material sorter.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions: A tea light and floating material sorter, comprising:

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

[0010] Further, an adsorption assembly is provided on the conveyor belt. The adsorption assembly includes two symmetrically arranged trapezoidal blocks fixed above the conveyor belt. A rotating shaft is rotatably connected between the two trapezoidal blocks. A partition plate penetrating the rotating shaft is fixed on the rotating shaft. Two mounting plates are fixed at both ends of the partition plate. Two symmetric electrostatic plates are provided between the two mounting plates.

The control assembly includes a slide rail fixed on the partition plate. A counterweight plate is slidably fitted on the slide rail. A first conductive sheet is provided on the counterweight plate, and a second conductive sheet is provided on the mounting plate.

[0012] Further, a cleaning assembly for cleaning light substances is provided on the conveyor belt. The cleaning assembly includes a support rod fixed on the trapezoidal block. A dust suction head is fixed on the support rod. A support seat is fixed on the support plate. An air suction fan is fixed on the support seat. The air inlet of the air suction fan is communicated with the dust suction head.

[0013] Further, a storage ball is provided between the air suction fan and the dust suction head.

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

[0015] 1. In the present invention, first, the electrostatic plate adsorbs light substances such as dust, and then the air suction fan cleans the electrostatic plate. During the process of dealing with light substances, the electrostatic plate not only plays a role in transferring light substances, but also can play a role in shielding the dust suction head, avoiding the situation that the dust suction head directly adsorbs light substances and inhaling tea leaves, reducing the waste of tea leaves.

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

[0032] Such as Figures 1-8As shown in the figure, a tea light floating material separator includes a color sorting component. The color sorting component includes a workbench 1. Above the workbench 1, there is a conveyor belt 11. The conveyor belt 11 is driven by a driving motor 14. Specifically, a support plate 111 is fixed above the conveyor belt 11, and the driving motor 14 is fixed on the upper surface of the support plate 111. The output shaft of the driving motor 14 and the driving shaft of the conveyor belt 11 are connected by a pulley and a belt. A protective shell is provided outside 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. At the output end of the conveyor belt 11, there are a sorting box 12 and a receiving hopper 13. The sorting box 12 is located above the receiving hopper 13. After the tea leaves are separated from the conveyor belt 11, they fall into the receiving hopper 13 in a parabolic shape. The bottom of the receiving hopper 13 is provided with a finished product material outlet and an impurity material outlet. The tea leaves are color sorted by the sorting box 12. The finished tea leaves fall into the finished product material outlet, and the impurities fall into the impurity material outlet;

[0033] A leveling component is provided on the support plate 111. The leveling component includes a screw rod 21 threadedly connected to the middle of the support plate 111. The screw rod 21 penetrates through the support plate 111. A handle 22 is fixed at the top of the screw rod 21. A scraping plate 23 is provided at the bottom end of the screw rod 21. When the tea leaves are conveyed on the conveyor belt 11, the scraping plate 23 levels the tea leaves, so that the tea leaves are evenly distributed in a single layer on the conveyor belt, avoiding the tea leaves from stacking together and interfering with each other, and improving the color sorting accuracy. Above the scraping plate 23, three fixing blocks 24 are fixed. The bottom end of the screw rod 21 is rotatably connected to the middle fixing block 24. Sleeves 25 are fixed on the two fixing blocks 24 on both sides. A sliding rod 26 is slidably fitted in the sleeve 25. The top end of the sliding rod 26 is fixed to the lower surface of the support plate 111. During specific operation, by rotating the handle 22 to drive the screw rod 21 to rotate, the height of the scraping plate 23 can be adjusted to be suitable for leveling different types of tea leaves, with a wide range of applications. In addition, when the sorting box 12 needs to be debugged or there are minor faults, 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 conveyance of the tea leaves, so that the sorting box 12 can be debugged or repaired without stopping the machine;

[0034] An adsorption component is provided on the conveyor belt 11. The adsorption component 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 technologies, such as driving the rotating shaft 32 to rotate intermittently through a hydraulic telescopic rod cooperating with a gear and a rack, or driving the rotating shaft 32 to rotate intermittently through a Geneva mechanism between the rotating shaft 32 and the driving shaft of the conveyor belt 11 (the specific driving method of the rotating shaft is not shown in the figure). A partition 33 penetrating 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, such as Figure 2As shown, when the rotating shaft 32 rotates intermittently, it rotates 180° each time. Two mounting plates 34 are fixed at both ends of the partition plate 33. Two symmetric static plates 35 are provided between the two mounting plates 34. A plurality of rubber strips are provided on the surface of the static plate 35 to prevent the light substances adsorbed on it from slipping when the static plate 35 is powered off. A control component for controlling the energization state of the static plate 35 is provided on the partition plate 33. The control component includes a slide rail 36 fixed on the partition plate 33. A counterweight plate 37 is slidably fitted on the slide rail 36. A first conductive sheet 371 is provided on the counterweight plate 37. 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 plate 33 are electrically connected to the static plate 35;

[0035] During specific operation, the counterweight plate 37 below the partition plate 33 slides down along the slide rail 36 under the action of gravity, so that the first conductive sheet 371 below the partition plate 33 is connected to the second conductive sheet 38, and the static plate 35 below the partition plate 33 is powered on. After the tea leaves are separated from the conveyor belt 11, the light substances such as dust and hair in the tea leaves are adsorbed by the static plate 35. When the rotating shaft 32 rotates, it drives the partition plate 33 and the static plate 35 to rotate synchronously. When the rotating shaft 32 rotates, the counterweight plate 37 slides in the direction away from the rotating shaft 32 under the action of centrifugal force. Therefore, when the rotating shaft 32 rotates, the two first conductive sheets 371 are respectively connected to the corresponding second conductive sheets 38, so that the two static plates 35 are both in the energized state, avoiding the situation that the adsorption effect becomes poor due to improper angle when the static plate 35 rotates. 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 above the partition plate 33 is separated from the second conductive sheet 38, and thus the static plate 35 above the partition plate 33 is powered off;

[0036] A cleaning component for cleaning light substances is provided on the conveyor belt 11. The cleaning component includes a support rod 41 fixed on the trapezoidal block 31. A dust suction head 42 is fixed on the support rod 41. A support seat 43 is fixed on the support plate 111. An air suction fan 44 is fixed on the support seat 43. The air inlet of the air suction fan 44 is communicated with the dust suction head 42. A storage ball 45 is provided between the air suction fan 44 and the dust suction head 42. Both ends of the storage ball 45 are respectively communicated with the dust suction head 42 and the air suction fan 44. A filter plate 46 is provided in the storage ball 45. A cleaning port 47 is provided at the top of the storage ball 45;

[0037] During specific operation, the air suction fan 44 generates suction force, so that the dust suction head 42 cleans the static plate 35 above the partition plate 33, and sucks the light substances such as dust and hair on the static plate 35 above the partition plate 33 into the storage ball 45. The filter plate 46 filters the light substances to prevent them from entering the interior of the air suction fan 44. When the color sorting work is completed, the end cover at the cleaning port 47 is opened, and the light substances are removed 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. When adjusting, rotate the handle 22 to drive the screw 21 to rotate. Under the action of thread fit, the scraping plate 23 is driven to move up or down, and the scraping plate 23 is adjusted to an appropriate height, so that the tea passes through the bottom of the scraping plate 23 and is evenly laid on the conveyor belt 11 in a single layer, avoiding the tea from stacking together and interfering with each other, and improving the color sorting accuracy.

[0040] Place the tea to be selected on the conveyor belt 11, power on the device and start the drive motor 14. The drive motor 14 drives the conveyor belt 11 to operate and transport the tea to the output end of the conveyor belt 11. After the tea separates from the output end of the conveyor belt 11, it falls in a parabolic shape. The sorting box 12 performs color sorting on the falling tea. The tea with good quality naturally falls into the finished product outlet at the bottom of the receiving hopper 13 along the parabola, and the impurities are blown into the impurity outlet at the bottom of the receiving hopper 13 by the spray valve of the sorting box 12.

[0041] After the tea separates from the output end of the conveyor belt 11, since the density of the tea is greater than that of dust or hair, the tea will separate from the dust or hair, and the dust or hair is located above the tea. Since the first conductive sheet 371 below the partition plate 33 is in an on state with the second conductive sheet when the rotating shaft 32 is in a static state, the electrostatic plate 35 below the partition plate 33 is synchronously powered on after the device is powered on. After the electrostatic plate 35 is powered on, it has an adsorption effect on the dust and hair, adsorbing the dust or hair on the electrostatic plate 35, avoiding the dust and hair from entering the receiving hopper 13, and improving the finished product quality.

[0042] When the rotating shaft 32 starts to rotate under the drive of the driving device, the two counterweight plates 37 both move away from the rotating shaft 32 under the action of centrifugal force, so that the two first conductive sheets are respectively connected to the corresponding second conductive sheets 38, so that the two electrostatic plates 35 are both in a powered-on state, avoiding the situation that the adsorption effect becomes poor due to improper angle when the electrostatic plate 35 rotates, and at the same time, it can also avoid the situation that the light substances such as dust slide down due to power-off when the electrostatic plate 35 below the partition plate 33 rotates to the upper part. When the rotating shaft 32 rotates 180° and then 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 above the partition plate 33 is separated from the second conductive sheet 38, so that the electrostatic plate 35 above the partition plate 33 is powered off, and the first conductive sheet 371 below the partition plate 33 continues to be connected to the corresponding second conductive sheet 38, and the electrostatic plate 35 below the partition plate 33 continues to adsorb the dust and hair. In addition, the electrostatic plate 35 also plays a role in shading, avoiding overexposure of the camera caused by external strong light irradiation, and further improving the color sorting accuracy.

[0043] The device is powered on to synchronously power on the suction fan 44. The suction fan 44 generates suction force, so that the suction head 42 cleans the electrostatic plate 35 above the partition plate 33, and sucks the light substances such as hair adsorbed on the electrostatic plate 35 above the partition plate 33 into the storage ball 45. The filter plate 46 filters the light substances to prevent the light substances from entering the suction fan 44 and affecting the service life of the suction fan 44. In the present invention, the electrostatic plate 35 adsorbs the light substances such as dust first, and then the suction fan 44 cleans the electrostatic plate 35 after adsorption. During the process of dealing with the light substances, the electrostatic plate 35 not only plays a role in transferring the light substances, but also can block the suction head 42 to avoid the situation that the suction head 42 directly adsorbs the light substances and inhales tea leaves, reducing the waste of tea leaves;

[0044] When the sorting box 12 needs to be temporarily adjusted or there is a minor fault, 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 transportation 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 substances in the storage ball 45 are centrally cleaned.

[0046] The above are only the 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 principle of the present invention shall be included in the protection scope of the present invention.
