[0040] The descending assembly 405 includes a descending shell 4051, a descending rod 4055 is slidingly provided at the bottom of the descending shell 4051, a descending plate 4052 is provided on the top of the descending rod 4055, a third positioning rod 4053 is provided on the top of the descending plate 4052, and the outer wall of the descending rod 4055 is provided with a fourth spring 4054 installed inside the descending shell 4051.

[0041] The fixed plate assembly 406 includes a fixed plate 4061 connected to the descending rod 4055, and mounting frames 4062 are installed on both sides of the top of the fixed plate 4061. A rubber plate 4065 is slidably set in the middle of the fixed plate 4061, and two mounting columns 4063 passing through the mounting frame 4062 are installed on both sides of the top of the rubber plate 4065. The outer wall of the mounting column 4063 between the mounting frame 4062 and the rubber plate 4065 is provided with a fifth spring 4064.

[0042] The two ends of the eighth pipeline 503 are connected to the housing 501 and the spray head 308 respectively, and the two ends of the seventh pipeline 502 are connected to the hot air blower 201 and the first diverter block 206 respectively.

[0043] The fifth pipeline 403 is installed on the top of one side of the second outer cylinder 4022 .

[0044] The lowering component 3 and the fixing component 4 and the pipes connected thereto are all filled with hydraulic oil, and the electrical components of the device are controlled by an intelligent control panel.

[0045] Working principle:

[0046] When using the device, first check the various components of the device to ensure that the various components of the device cooperate properly and that the device can work normally.

[0047] When using the device, first power on the device to ensure that the electrical components that require power connection can work.

[0048] S1. When the device is working, the flow channel component 1 first transfers its corrugated cardboard to the shell installed on the flow channel component 1. When the corrugated cardboard is transferred to the shell installed on the flow channel component 1, the flow channel component 1 stops working and no longer transfers the corrugated cardboard.

[0049] S2. After the corrugated cardboard is transported into the shell installed on the flow channel assembly 1, the vertical blowing assembly 2 is started, and the hot air blower 201 works to generate hot flow gas and discharge the hot air into the shell installed on the flow channel assembly 1 through the first pipe 205 and the hot air head 204 installed on the vertical blowing assembly 2, thereby drying the corrugated cardboard entering the shell installed on the flow channel assembly 1.

[0050] S3. When the corrugated cardboard reaches a certain position and the flow channel assembly 1 stops working, the driver 302 is started. The driver 302 starts to drive the first sealing plate 3012 and the lower extension rod 3015 to move in the installation outer cylinder 3011. When the lower extension rod 3015 moves, it drives the installation block 307 and the spray head 308 to move. The first sealing plate 3012 moves to push the hydraulic oil in the installation outer cylinder 3011 into the second pipeline 305. The hydraulic oil passes through the second pipeline 305 and the second diverter block 309. , the third pipeline 310, the connecting ring 408 and the fourth pipeline 401 enter the pushing assembly 402. When the first sealing plate 3012 moves to the top of the trigger plate 3016, the first process of the driver 302 ends. When the mounting block 307 moves, it drives the connecting block 504 to slide in the connecting shell 501. When the first process of the driver 302 ends, the connecting block 504 moves to the middle position of the connecting shell 501, and the mounting block 307 and the ejection head 308 are not attached to the top of the flow channel assembly 1.

[0051] Through the two-process design of the driver 302, when the device is working, the fixing component 4 is first implemented to fix the corrugated cardboard in advance, thereby preventing the corrugated cardboard from being moved by the wind during subsequent blowing.

[0052] S4. After the hydraulic oil enters the pushing component 402, it first passes through the first outer cylinder 4021. The hydraulic oil squeezes the second squeezing plate 4025 to move inside the first outer cylinder 4021. The second squeezing plate 4025 moves to push the pressure rod 4023 to move. When the second squeezing plate 4025 moves to the limit, the positioning plate 4028 limits the movement of the second squeezing plate 4025. When the pressure rod 4023 moves, the pressure rod 4023 pushes the first squeezing plate 4024. The first squeezing plate 4024 pushes the hydraulic oil inside its second outer cylinder 4022 through the fifth pipeline 403. When the first squeezing plate 4024 moves, the third spring 4027 moves into the pressure rod 4023, and the first squeezing plate 4024 moves to compress the through rod 4026.

[0053] By providing the pushing component 402 and adopting a segmented design, it is possible to avoid the outer cylinder 3011 being designed too large, while ensuring that the hydraulic oil inside the pushing component 402 can be supplied to the two second pipelines 305 for use, thereby ensuring the normal operation of the device.

[0054] S5. After the hydraulic oil enters the interior of the descending assembly 405 through the fifth pipeline 403 and the sixth pipeline 404, the hydraulic oil pushes the descending plate 4052 to move inside the descending shell 4051. The hydraulic oil pushes the descending plate 4052 to move, driving the descending rod 4055 to move. The descending plate 4052 moves to compress the fourth spring 4054. The descending rod 4055 moves to drive the fixed plate assembly 406 to descend.

[0055] S6. After the fixing plate assembly 406 contacts the corrugated cardboard, the fixing plate assembly 406 continues to descend, and the rubber plate 4065 moves upward in the fixing plate 4061. The rubber plate 4065 moves upward so that its two mounting posts 4063 slide on the mounting frame 4062. The rubber plate 4065 moves to compress the fifth spring 4064, and the rubber plate 4065 fixes the corrugated cardboard.

[0056] The fixed plate assembly 406 adopts this design to avoid the corrugated cardboard from being crushed due to excessive pressure in the device, thereby ensuring the yield of the corrugated cardboard.

[0057] S7. The driver 302 continues to start the second process, prompting the first sealing plate 3012 to continue to move. When the first sealing plate 3012 moves, it pushes the trigger plate 3016 to move. The movement of the trigger plate 3016 drives the two limiting rods 3017 to move. When the trigger plate 3016 moves, it compresses the second spring 3018. When one of the limiting rods 3017 moves, it drives the connecting plate 3019 and the sealing disc 3020 to move. When the first sealing plate 3012 moves, the excess hydraulic oil inside the outer cylinder 3011 in which it is installed is pushed into 2031 through the overflow groove and the through hole. The hydraulic oil pushes the second sealing plate 3063 to move upward. The movement of the second sealing plate 3063 drives the positioning rod 3066 to move. The movement of the second sealing plate 3063 compresses the first spring 3065.

[0058] By providing the recovery component 306, it is possible to collect the excess hydraulic oil inside the outer cylinder 3011 to ensure the normal operation of the device.

[0059] S8. When the first sealing plate 3012 moves to the limit, the mounting block 307 contacts the top of the flow channel assembly 1.

[0060] S9. After the mounting block 307 contacts the top of the flow channel assembly 1, the connecting block 504 connects the seventh pipeline 502 and the eighth pipeline 503, and the hot air blows the corrugated cardboard placed on the flow channel assembly 1 through the first diverter block 206, the connecting assembly 5 and the first diverter block 206 to dry the middle part of the corrugated cardboard.

[0061] The cooperation between the mounting block 307 and the connection component 5 can achieve that air is blown only after the corrugated cardboard is fixed. When it is not fixed, the device will not blow air, thereby avoiding the problem of the corrugated cardboard being blown off course due to continuous blowing.

[0062] S10. After drying a piece of corrugated cardboard, the driver 302 rotates in the opposite direction, causing the device to move in the opposite direction. The hydraulic oil set in the recovery component 306 is first pushed into the interior of the installation outer cylinder 3011. After the hydraulic oil in the recovery component 306 is pushed into the interior of the installation outer cylinder 3011, the hydraulic oil in the fixing component 4 is gradually pushed into the installation outer cylinder 3011. The descending component 405 and the fixing plate component 406 no longer fix the corrugated cardboard. When the device is reset, the descending component 405 is reset, cutting off the connection between the seventh pipeline 502 and the eighth pipeline 503, so that the recovery component 306 no longer blows air.

[0063] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
