Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The diagram shown is a structural schematic of an automatic bamboo leaf sorting device according to an embodiment of the present invention, comprising:

[0031] Screening station 1;

[0032] The first downhill slope 2 and the second downhill slope 3 are set at both ends of the screening table 1;

[0033] The groove 17 is located at the lower end of the middle part of the screening table 1, and a glass plate 4 is provided on the top.

[0034] A rotary drive structure is located at the upper part of the middle section of the screening table 1.

[0035] The screening structure is located in the middle of the screening table 1 to identify bamboo leaves;

[0036] The interception structure is located to the right of the screening structure and is used to intercept and collect defective products.

[0037] In this embodiment of the invention, when in use, when the bamboo leaves are transported to the glass plate 4 via the first downhill section 2 through the transmission device, the rotation of the rotation drive structure causes the bamboo leaves to move automatically, and the bamboo leaves are screened in cooperation with the screening structure and the interception structure.

[0038] By setting a screening structure in the middle of the screening table 1, the upper and lower sides of the passing bamboo leaves can be screened, thereby improving the quality control of the bamboo leaves. An interception structure is set at the right end of the screening table 1, which can intercept and remove the screened defective products, thereby reducing the trouble of subsequent screening.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment of this utility model, a cleaning structure is also provided on the right side of the interception structure to rinse the bamboo leaves. The cleaning structure includes a water tank 14, a support plate 19, and an electric water pumping pipe 18. An inclined groove 16 is arrayed on the outer side of the right end of the glass plate 4. The water tank 14 is inserted into the outer side of the right end of the screening table 1, and a filter screen 24 is provided at the top. The support plate 19 is symmetrically arranged on the upper and lower sides of the inclined groove 16, and a temporary storage box 21 is arranged on the facing side, and a water spraying pipe 20 is arrayed. An electric on / off valve 23 is fixedly installed at the rear end of the temporary storage box 21. The electric water pumping pipe 18 is located inside the water tank 14 and passes through the rear side of the screening table 1. A water distribution pipe 22 is fixedly connected to it. The front side of the water distribution pipe 22 is fixedly connected to the electric on / off valves 23 on the upper and lower sides respectively.

[0040] In this embodiment of the utility model, when the bamboo leaf moves to the top of the inclined groove 16, the electric water pumping pipe 18 is activated to pump the water in the water tank 14 into the water distribution pipe 22 through the electric water pumping pipe 18, and the electric on / off valve 23 is opened so that the water in the water tank 14 enters the temporary storage box 21 on the surface of the upper and lower support plates 19 respectively. Then, the water spraying pipe 20 inside the upper temporary storage box 21 sprays water onto the upper side of the bamboo leaf, while the water spraying pipe 20 inside the lower temporary storage box 21 sprays water onto the lower side of the bamboo leaf through the inclined groove 16.

[0041] By setting up a cleaning structure, water is sprayed on both sides of the bamboo leaves through the cooperation of the upper and lower water spray pipes 20, thus keeping the bamboo leaves clean and facilitating subsequent processing.

[0042] like Figure 2 As shown, in a preferred embodiment of the present invention, the interception structure includes a defect box 11, a through groove 13 and an electric rotating limit guide plate 12. The through groove 13 is opened in the middle of the right end of the glass plate 4. The defect box 11 is movably inserted into the lower part of the through groove 13. The electric rotating limit guide plate 12 is movably disposed inside the through groove 13.

[0043] In this embodiment of the utility model, when in use, the electric rotating limiting guide plate 12 in the through groove 13 is activated, causing the through groove 13 to open, and then the defective bamboo leaves hit the inner side of the electric rotating limiting guide plate 12, thereby entering the defective box 11.

[0044] By setting up an interception structure, unqualified bamboo leaves can be intercepted and collected, and with the support of the electric rotating limit guide plate 12, qualified bamboo leaves can pass smoothly above the channel 13, thus facilitating the cleaning of bamboo leaves.

[0045] like Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, the screening structure includes a positioning plate 9 and a display control terminal 15. The positioning plate 9 is symmetrically arranged at the upper and lower ends of the middle of the glass plate 4. A comparison camera 10 is arranged on the inner side of the positioning plate 9 to screen the bamboo leaves. The display control terminal 15 is symmetrically arranged on the front side of the screening table 1 and is wired to the comparison camera 10.

[0046] In this embodiment of the utility model, when the bamboo leaf moves to the working area of ​​the comparison camera 10 at the inner end of the upper and lower positioning plates 9 through the rotation drive structure, the comparison camera 10 on the upper and lower sides can capture images of the upper and lower sides of the bamboo leaf and display them on the display control terminal 15.

[0047] By setting up a screening structure, the bamboo leaves on the glass plate 4 can be photographed from both the top and bottom sides, allowing for comparison and judgment of the quality of the bamboo leaves, thereby speeding up the screening process.

[0048] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in a preferred embodiment of the present invention, the rotary drive structure includes a rotary rod 5 and a top block 8. The rotary rod 5 is arranged in an array at both ends of the top of the screening table 1, and a transmission belt 6 is provided on its surface. A traction belt 7 is provided on the outer side of the transmission belt 6, and the top block 8 is arranged in an array on the inner side of the traction belt 7 to push the bamboo leaves.

[0049] In this embodiment of the utility model, when in use, the rotating rod 5 at one end of the screening table 1 is activated, which causes all the transmission belts 6 to rotate synchronously, and the traction belt 7 to rotate synchronously with the transmission belts 6, thereby driving the top block 8 to push the bamboo leaves.

[0050] By setting up a rotating drive structure, the bamboo leaves can be moved from left to right, thus enabling the bamboo leaves to undergo subsequent screening and cleaning.

[0051] like Figure 2 As shown, in a preferred embodiment of the present invention, the length of the electric rotating limiting guide plate 12 is equal to the length of the through groove 13, and an arc plate is provided at the bottom of the right end of the electric rotating limiting guide plate 12.

[0052] In this embodiment of the utility model, when in use, the length of the electric rotating limiting guide plate 12 is made equal to the length of the through groove 13, thereby facilitating the electric rotating limiting guide plate 12 to enter and exit the through groove 13. An arc plate is provided at the bottom of the right end of the electric rotating limiting guide plate 12, which can guide and intercept the passing bamboo leaves.

[0053] like Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, the first downslope 2 and the second downslope 3 on both sides are staggered, and the top of the second downslope 3 is equal to the bottom of the first downslope 2.

[0054] In this embodiment of the invention, when in use, the first lower slope 2 and the second lower slope 3 on both sides are staggered, and the top of the second lower slope 3 is equal to the bottom of the first lower slope 2, thereby facilitating the entry and exit of the bamboo leaves.

[0055] The present invention provides an automatic bamboo leaf screening device in the above embodiments. When in use, the defective box 11 and the water tank 14 are inserted into the groove 17 at the lower end of the screening table 1, and the rotating rods 5 at both ends of the screening table 1 are started, which causes all the transmission belts 6 to rotate synchronously, and then the traction belt 7 rotates synchronously with the transmission belts 6.

[0056] Then, when the bamboo leaf is transported to the glass plate 4 via the first downhill section 2 through the transmission device, the top block 8 will move to the surface of the glass plate 4 due to the rotation of the traction belt 7, pushing the bamboo leaf from left to right, thereby moving the bamboo leaf to the working area of ​​the comparison camera 10 at the inner end of the upper and lower positioning plates 9, so that the comparison camera 10 can compare and judge the quality of the upper and lower sides of the bamboo leaf, and display it on the display control terminal 15;

[0057] When a defective product is found, the electric rotating limit guide plate 12 inside the through slot 13 is activated, causing the through slot 13 to open. This causes the bamboo leaf to hit the inside of the electric rotating limit guide plate 12 and enter the defective box 11. Then the electric rotating limit guide plate 12 reverses, allowing qualified bamboo leaves to pass through the top of the through slot 13.

[0058] When the qualified bamboo leaves pass over the through groove 13 and move to the top of the inclined groove 16, the electric water pumping pipe 18 is then activated to pump water from the water tank 14 into the water distribution pipe 22. The electric on / off valve 23 is then opened, allowing the water from the water tank 14 to enter the temporary storage boxes 21 on the surface of the upper and lower support plates 19. Water is then sprayed onto the upper side of the bamboo leaves through the spray pipe 20 inside the upper temporary storage box 21, while water is sprayed onto the lower side of the bamboo leaves through the inclined groove 16 through the spray pipe 20 inside the lower temporary storage box 21. The combined action of the upper and lower spray pipes 20 sprays water onto both sides of the bamboo leaves, keeping them clean and facilitating subsequent processing.

[0059] The rinsed water will return to the water tank 14 through the inclined channel 16, and then be filtered by the filter screen 24 at the top of the water tank 14, so that the clean water returns to the bottom of the water tank 14, thereby realizing the recycling of water resources.

[0060] After being rinsed, the bamboo leaves will fall to the designated location under the guidance of the second downhill slope 3.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
