[0042] In order to make the above and other features and advantages of the present invention more clear, the present invention is further described below with reference to the accompanying drawings. It should be understood that the specific embodiments given herein are for the purpose of explaining to those skilled in the art and are only exemplary and not restrictive.

[0043] Combine Figures 1 to 7 According to an embodiment of the present utility model, a purge mechanism is provided, including a base plate 1, a cover shell 2, a purge assembly 3, a conveying assembly 4, a conveying track 5, a frame 6, a dust hood 7, a lifting cylinder 8, a position sensor 9 and a blocking cylinder 10.

[0044] like Figure 1 and Figure 2 As shown, according to the embodiment of the present invention, the cover 2 and the conveying track 5 are installed on the bottom plate 1, and the conveying track 5 is placed in the cover 2. The cover 2 has an opening K, and the conveying assembly 4 is arranged along the conveying direction (such as Figure 2 The raw material (shown) is transported from the opening K of the housing 2 to the interior of the housing 2.

[0045] like Figure 3 and Figure 4 As shown, the conveying track 5 is placed in the cover 2, and a frame 6 is fixed on the conveying track 5. Specifically, a fixing block is provided on the conveying track 5, and the frame 6 is fixed on the fixing block.

[0046] like Figure 3 and Figure 4 As shown, according to an embodiment of the present invention, a purge assembly 3 is installed on the top of the housing 2 inside the housing 2. The purge assembly 3 is arranged just above the frame 6.

[0047] like Figure 5 As shown, the purge assembly 3 includes an air nozzle moving cylinder 301, which is fixed to the top of the cover 2, and the output end 302 of the air nozzle moving cylinder 301 is connected to the air nozzle connecting block 306, an air nozzle (not shown in the figure) is installed at the bottom of the air nozzle connecting block 306, and an air inlet connector 307 is installed on one side of the air nozzle connecting block 306.

[0048] The air nozzle moving cylinder 301 drives the air nozzle connecting block 306 to reciprocate in a direction perpendicular to the conveying direction, thereby driving the air nozzle to reciprocate in a direction perpendicular to the conveying direction.

[0049] Furthermore, the purge assembly 3 also includes an adjustment bracket 305, the output end 302 of the air nozzle moving cylinder 301 is fixed to the adjustment bracket 305, and the adjustment bracket 305 is connected to the air nozzle connecting block 306 for adjusting the height of the air nozzle connecting block 306, thereby adjusting the height of the air nozzle.

[0050] Furthermore, the purge assembly 3 further includes a guide rail 303 , which is fixed to the top of the housing 2 . A slider 304 is mounted on the guide rail 303 , and the slider 304 is fixed to the adjustment bracket 305 .

[0051] The output end 302 of the air nozzle moving cylinder 301 drives the adjusting bracket 305 to reciprocate in a direction perpendicular to the conveying direction, and the adjusting bracket 305 drives the air nozzle connecting block 306 to reciprocate in a direction perpendicular to the conveying direction, thereby driving the air nozzle to reciprocate in a direction perpendicular to the conveying direction.

[0052] When the output end 302 of the air nozzle moving cylinder 301 drives the adjusting bracket 305 to reciprocate in a direction perpendicular to the conveying direction, the slider 304 reciprocates along the guide rail 303 to guide the adjusting bracket 305 .

[0053] Combine Figure 4 、 Figure 6 and Figure 7 In the housing 2 , a conveying assembly 4 is disposed on the conveying track 5 . The conveying assembly 4 includes a conveying plate 401 and a nozzle plate 402 fixed on the conveying plate 401 , on which a tray 403 is placed.

[0054] Specifically, the conveying plate 401 and the suction nozzle plate 402 are connected by a connecting piece 404 , thereby fixing the conveying plate 401 and the suction nozzle plate 402 .

[0055] The conveying plate 401 is placed on the conveying track 5 and reciprocates along the conveying direction, driving the suction nozzle plate 402 to reciprocate along the conveying direction, thereby driving the tray 403 placed on the suction nozzle plate 402 to move into the frame 6 or the tray 402 to move out of the frame 6.

[0056] like Figure 7 As shown, the tray 403 has a plurality of product positions 4031, which are used to place products (such as liner boards). In this embodiment, the tray 403 has 8 product positions.

[0057] The nozzle plate 402 is provided with a plurality of nozzle blocks 4021, each nozzle block 4021 corresponding to a product position 4031, and each nozzle block 4021 is provided with a plurality of nozzles 4022. In this embodiment, the nozzle plate 402 is provided with eight nozzle blocks 4021, and each nozzle block 4021 is provided with four nozzles 4022.

[0058] The tray 403 is placed on the suction nozzle plate 402 , and the suction nozzle block 4021 is embedded in the product position 4031 . When the suction nozzle 4022 is vacuumed, the suction nozzle 4022 absorbs the product (such as a liner) placed in the product position 4031 .

[0059] Furthermore, a detection sensor 4023 is provided on the nozzle block 4021 for detecting whether a product (eg, a liner) is placed in the product position 4031 .

[0060] Combine Figure 2 and Figure 4 According to an embodiment of the present invention, a lifting cylinder 8 is fixed on the bottom plate 1 and is located directly below the conveying track 5. When the conveying plate 401 drives the tray 403 into the frame 6, the lifting cylinder 8 lifts the conveying assembly 4 as a whole, thereby lifting the tray 403 upward.

[0061] like Figure 4 As shown, a position sensor 9 is installed on the conveying track 5, and a blocking cylinder 10 is fixed on the base plate 1. The position sensor 9 is located at the end of the frame 6, and the blocking cylinder 10 is located at the end of the frame 6.

[0062] When the conveying plate 401 drives the tray 403 to move into the frame 6, the position sensor 9 detects the position of the conveying plate 401. After the position sensor 9 detects that the conveying plate 401 is in place, the blocking cylinder 10 rises to block the conveying plate 401, thereby placing the tray 403 in the purge position.

[0063] Back to Figure 2 and Figure 3 According to an embodiment of the present invention, a dust hood 7 is mounted on the frame 6, facing the purge assembly 3. When the purge airflow from the air nozzle (not shown) mounted at the bottom of the air nozzle connection block 306 of the purge assembly 3 blows the upper surface of the products placed in the product position 4031 of the tray 403, dust generated on the product surface is sucked into the fixed collection mechanism through the dust hood 7, thereby preventing secondary contamination of the products.

[0064] The following combination Figure 1 The figure illustrates the working process of a purge mechanism provided by the present invention.

[0065] First, place a product (such as a liner) at the product position 4031 of the tray 403 , and place the tray 403 on the nozzle plate 402 , with each nozzle block 4021 of the nozzle plate 402 embedded in the corresponding product position 4031 of the tray 403 .

[0066] The conveying plate 401 moves along the conveying direction on the conveying track 5 to convey the tray assembly 4 from the opening K of the cover shell 2 to the interior of the cover shell 2 .

[0067] When the conveying plate 401 drives the tray 403 to move into the frame 6, the position sensor 9 detects the position of the conveying plate 401. After the position sensor 9 detects that the conveying plate 401 is in place, the blocking cylinder 10 rises to block the conveying plate 401, thereby placing the tray 403 in the purge position.

[0068] Then, the lifting cylinder 8 is pushed upward to lift the conveying assembly 4 as a whole, thereby lifting the tray 403 upward to a suitable position.

[0069] The detection sensor 4023 of each nozzle block 4021 on the nozzle plate 402 detects whether a product (e.g., a liner) is placed in the corresponding product position 4031 of the tray 403. When the detection sensor 4023 of a nozzle block 4021 detects the presence of a product in the corresponding product position 4031, the nozzle 4022 of the nozzle block 4021 is vacuumed to absorb the product in the corresponding product position 4031.

[0070] Then, the compressed air is fed into the air nozzle connecting block 306 through the air inlet joint 307 on one side of the air nozzle connecting block 306 , so that the air nozzle (not shown in the figure) installed at the bottom of the air nozzle connecting block 306 generates a purge airflow.

[0071] Then, the output end 302 of the air nozzle moving cylinder 301 drives the adjusting bracket 305 to reciprocate in a direction perpendicular to the conveying direction, and the adjusting bracket 305 drives the air nozzle connecting block 3065 to reciprocate in a direction perpendicular to the conveying direction, so that the air nozzle reciprocates in a direction perpendicular to the conveying direction above the tray 403, and the air nozzle generates a purge airflow to clean the dust and dirt on the upper surface of the product in the product position 4031 of the tray 403.

[0072] In one embodiment, the height of the air nozzle is adjusted by adjusting the bracket 305 to adjust the height of the air nozzle, so that the air nozzle maintains a suitable distance from the upper surface of the product in the product position 4031 of the tray 403 .

[0073] After cleaning the dust and dirt from the product surface, lift cylinder 8 moves downward to reset, causing conveyor assembly 4 to move downward as a whole, placing conveyor plate 401 on conveyor track 5. Suction nozzle 4022 of nozzle block 4021 breaks the vacuum, releasing the product from product position 4031 and blocking the descent of cylinder 10. Conveyor plate 401, on conveyor track 5, moves in the opposite direction of the conveying direction, removing tray assembly 4 from housing 2 through opening K. Tray 403 is then removed from nozzle plate 402 and sent to the next process.

[0074] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
