Description

Technical Field

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

[0002] The color sorting of tea refers to the process of selecting and classifying the color of tea during the tea processing. The main purpose of this process is to ensure the beautiful appearance and stable quality of tea. At the same time, it also affects the market price of tea and the choice of consumers. Color sorting can remove the miscellaneous colors, breakage and parts that do not meet the appearance requirements in tea, ensuring the beautiful appearance and stable quality of the whole tea. At the same time, it can also remove some impurities such as branches and feathers in tea. This is particularly important for high-grade tea because consumers often judge the quality and value of tea by its appearance.

[0003] Currently, when sorting tea, after increasing the moving speed of the tea and making it thrown out, during the process of the tea making a parabolic motion, an infrared detection device is used to sense the impurities in the tea, and then the corresponding air nozzles are controlled to spray air, so that part of the tea with impurities is blown away, thereby improving the quality of the tea. However, during the process of accelerating the tea, a long conveyor belt needs to be set, which requires a large floor area. Especially when multi-stage color sorting of tea is needed to further improve the quality, the floor area occupied by the equipment is extremely large, which may pose challenges in factory layout and space utilization. In view of this, the utility model proposes a waterfall type color sorter. Summary of the Utility Model

[0004] The purpose of the utility model is to propose a waterfall type color sorter for the problem that when multi-stage color sorting of tea is needed to further improve the quality, the floor area occupied by the equipment is extremely large, which may pose challenges in factory layout and space utilization in the background art.

[0031] Embodiment

[0032] As Figures 1-3 shown, a waterfall type color sorter proposed by the present utility model includes a frame 1. A feed hopper 2 is installed at the top of the frame 1. Feeding is carried out above the feed hopper 2, and uniform feeding is carried out through a flexible vibrating disk (the purpose of the flexible vibrating disk is to make the tea leaves evenly distributed after vibration, which is prior art and will not be elaborated here). This ensures a high uniformity of the tea leaves entering the feed hopper 2, thereby preventing the tea leaves from accumulating during movement and improving the accuracy of impurity detection. Three groups of miscellaneous color sensing mechanisms 3 are arranged below the feed hopper 2. The three groups of miscellaneous color sensing mechanisms 3 are arranged in a stepped manner, which is convenient for multi-level screening of the tea leaves and improves the accuracy of color sorting. Each of the three groups of miscellaneous color sensing mechanisms 3 includes a fixed block 31 installed in the frame 1. A slideway 32 for the tea leaves to pass through is provided in the fixed block 31. An infrared detection module 33 is arranged inside the slideway 32. The infrared detection module 33 is used to irradiate the tea leaves and detect the tea leaves when they pass by, so as to timely detect the impurities carried in the tea leaves. A supplementary light 34 facing the infrared detection module 33 is also arranged in the slideway 32. The supplementary light 34 is used to increase the brightness, thereby improving the accuracy of the infrared detection module 33 when detecting the tea leaves. A discharge cylinder 35 is installed at the bottom of the fixed block 31, which is convenient for the tea leaves to be directly discharged downward.

[0033] Further, the above color sorter includes three groups of air jet impurity removal mechanisms 4 respectively arranged in the three groups of miscellaneous color induction mechanisms 3. The air jet impurity removal mechanism 4 is used to separate impurities in the tea. The air jet impurity removal mechanism 4 includes an air jet module 41 installed at the bottom of the fixed block 31. A number of groups of air pipes 42 are connected to the air jet module 41. After receiving the position information of the tea impurities sensed by the infrared detection module 33, the air jet module 41 controls the corresponding air pipes 42 to discharge air. The inner wall of the slideway 32 is fixedly connected with a fixed plate 43. A number of groups of nozzles 44 are installed on the fixed plate 43. The fixed plate 43 keeps the positions of the nozzles 44 fixed. One ends of the number of groups of air pipes 42 far away from the air jet module 41 respectively penetrate through the fixed plate 43 and communicate with the number of groups of nozzles 44. After the air pipes 42 discharge air, they drive the nozzles 44 communicated with them to blow air, so as to blow off the part of the tea with impurities from its original moving path. The fixed plate 43 is arranged at the position between the infrared detection module 33 and the supplementary light 34, and the fixed plate 43 is located below the infrared detection module 33 and the supplementary light 34. The tea moves to the position of the fixed plate 43 after being detected by the infrared detection module 33. A miscellaneous material hopper 45 is arranged on one side of the discharge cylinder 35 far away from the fixed plate 43. The miscellaneous material hopper 45 is installed in the fixed block 31 and communicated with the slideway 32, which is convenient for the nozzles 44 to blow the tea with impurities into the miscellaneous material hopper 45 when blowing air. The two upper miscellaneous material hoppers 45 are communicated through a centralized pipe 46. An installation box 47 is arranged at the bottom of the centralized pipe 46, which is convenient for the tea with impurities in the primary color sorting and secondary color sorting to be concentrated together. A first conveyor belt 48 is installed in the installation box 47. A first servo motor 49 is installed on one side of the frame 1. The first servo motor 49 is used to drive the first conveyor belt 48 to move, which is convenient for the output of the tea with impurities and convenient for centralized collection, so that a part of the intact tea can be recycled from it, reducing the loss of tea during color sorting.

[0034] Furthermore, the above color sorter further includes a guiding component 5 installed on the three groups of fixed blocks 31. The guiding component 5 is used to guide the tea. The guiding component 5 includes a first guiding hopper 51 arranged below the feed hopper 2. The first guiding hopper 51 is installed on the top of the uppermost group of fixed blocks 31. A second guiding hopper 52 is arranged between adjacent two groups of fixed blocks 31. The second guiding hopper 52 is fixed on the frame 1. The first guiding hopper 51 and the second guiding hopper 52 are used to guide the tea when it moves, so that the moving path of the tea is correct and the tea is prevented from scattering.

[0035] Finally, the above color sorter includes a second conveyor belt 61 disposed below the lowermost set of discharge cylinders 35. The second conveyor belt 61 is used to output tea without impurities. A third conveyor belt 62 is disposed below the lowermost set of waste hoppers 45. The third conveyor belt 62 is used to output tea with impurities. A second servo motor 6 is installed on the frame 1. The second servo motor 6 is used to drive the second conveyor belt 61 and the third conveyor belt 62 to move synchronously, sharing a set of second servo motors 6 to reduce energy consumption. Two sets of symmetrically arranged guide plates 63 are respectively disposed at the tops of the second conveyor belt 61 and the third conveyor belt 62. The guide plates 63 are fixed to the frame 1 to prevent the tea from scattering during transportation.

[0036] In this embodiment, first, the tea dispersed by the flexible vibrating disk enters the feed hopper 2. After being guided by the feed hopper 2, it is then guided by the first guiding hopper 51 into the first set of fixing blocks 31 and slides in the first set of chutes 32. The tea is irradiated by the supplementary light lamp 34 and then detected by the infrared detection module 33. When impurities are contained in the tea, the infrared detection module 33 promptly detects the impurities and sends the position information of the impurities to the jetting module 41. At this time, the tea continues to move downward. When the tea moves to the position of the fixing plate 43, the jetting module 41 receives the impurity position information and controls the corresponding air pipe 42 to discharge air, and at the same time, the corresponding nozzle 44 jets air to blow the tea in the entire area containing impurities into the waste hopper 45. Thus, the tea without impurities or with less impurities is discharged through the first set of discharge cylinders 35 and enters the second set of fixing blocks 31 after being guided by the first set of second guiding hoppers 52. The tea is subjected to secondary impurity removal in the same treatment manner as above. At this time, the tea with impurities is concentrated into the installation box 47 through the concentrating pipe 46, and after the first servo motor 49 is started, it drives the first conveyor belt 48 to move to discharge the tea with impurities. A material box is placed below the discharge end of the first conveyor belt 48 to recycle the tea with impurities. The tea that has undergone the second impurity removal enters the third set of fixing blocks 31 for the third impurity removal, so that the tea discharged through the lowermost set of discharge cylinders 35 is free of impurities, and the impurity removal accuracy is extremely high, improving the quality of the tea product. Also, a material box is provided below the discharge end of the third conveyor belt 62 to receive the tea with impurities, facilitating the recycling of the intact tea therein and reducing the loss of tea during the color sorting process.

[0037] The above specific embodiments are merely an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
