The specific implementation method is as follows:

[0017] The operator first transports the corrugated box to the top of the lifting plate through the conveyor line, and then starts the lifting cylinder to lift the lifting plate, and then continues to start the movable cylinder to drive the clamping parts at both ends of the movable circular cover plate to move closer together, until the resistance block touches the fins on the corrugated box, and then continues to move relative to each other, squeezing the resistance block to slide toward the inner cavity of the movable frame, and the edge of the movable groove of the movable frame squeezes the bending rod inward, and the fixed wedge block on the bending rod clamps the fins on the corrugated box to complete the clamping. Even if the corrugated box is rotating, the fixed wedge block pulls the bending rod to continue bending, and the corrugated box will not be separated from the clamping parts. Due to the different spacings on different corrugated boxes, before touching the resistance block, it first collides with the guide cone. After the two groups of guide cones first pass into the gap between the fins of the corrugated box, the first thrust spring is squeezed to drive the movable frame to slide on the moving rod, and the resistance block is correctly guided to the fin surface of the corrugated box, so as to achieve adaptation to the fins of the corrugated box with different gaps.

[0018] After the clamping is completed, the driving roller is started to drive the corrugated box to slide to the center of the rust removal pipe, and the two ends of the rust removal pipe are closed by the movable circular cover plate, and then the lifting cylinder is started to slowly lift the leakage trough to connect with the leakage trough on the rust removal pipe, and then the lifting cylinder is started to slowly lift the push plate to slowly pass the friction material in the material receiving box into the rust removal pipe, and at the same time, the driving motor is started to flip the clamping part to flip the corrugated box. In the process of gradually increasing friction material, the early bending plate drives the friction material to fall and hit the fins of the corrugated box to loosen the rust. After that, after the friction material increases, it has a grinding effect. After the rust removal is completed, the rust material falls between the friction materials, and the lifting cylinder continues to descend, and the friction material falls into the material receiving box, and the collection of the rust material is completed. Then the rotating motor is started to rotate the rotating ring until other material receiving boxes are replaced to the bottom of the leakage trough to complete the update of the friction material;

[0019] When the friction material in the material receiving box needs to be cleared, the lifting cylinder is started to vibrate up and down. Since the rust material is fine and broken, it is very easy to fall under the material receiving box. There is a grid or hole in the middle of the push plate, and then it flows out through the grid or hole on the push plate.

[0020] Since there are clamping mechanisms on both sides of the bellows, if you are worried about the poor treatment effect, start the clamping part and move it to the top of the lifting plate. After the lifting plate is lifted up by the lifting cylinder and presses against the bottom surface of the bellows, the clamping part releases the clamping and starts the lifting cylinder to descend. During the descent of the lifting cylinder, the abutment area of ​​the movable teeth is converted from the linear guide to the rotating guide, driving the lifting plate to rotate during the descent, completing the direction change on the lifting plate, and continuing to repeat the above operations can realize the change of different clamping surfaces to meet the rust removal needs.

[0021] After rust removal is completed, start the driving roller to slide the movable circular cover to move the corrugated box to the middle of the oil removal pipe. The movable circular cover will tightly buckle the two ends of the oil removal pipe, and then the water in the water storage tank will be pumped into the center of the oil removal pipe through the liquid outlet pipe until the water overflows from the opening of the oil removal pipe. The rotating drive motor drives the corrugated box to rotate, and the fat-soluble cleaning material in the water flow removes the grease on the corrugated box and agglomerates, drifting above the water surface, and flows out through the opening of the oil removal pipe until no agglomerates flow out. Then, start the solenoid valve to let the remaining water in the movable circular cover fall into the water storage tank to complete the recovery. After that, the driving roller can be started to drive it to the relevant transport line through the sliding guide rail to complete the rust removal and cleaning of the corrugated box. At the same time, the rust removal and cleaning can be carried out in the opposite order, depending on the actual situation.

[0022] The equipment has a simple structure and can effectively handle the rust removal process of corrugated boxes of different sizes. At the same time, rust materials can be centrally processed or collected. It also has a good cleaning effect on corrugated boxes with deeper fins. It has good practicality and is beneficial to the promotion and use of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] In practice, the lifting cylinder 45 is started to descend. During the descent of the lifting cylinder 45, the abutment area of ​​the movable tooth 4221 is transferred from the linear guide rail 4211 to the rotating guide rail 4212, driving the lifting plate 42 to rotate during the descent, thereby completing the change of direction on the lifting plate 42.

[0050] Working principle of the present invention:

[0051] The operator first transports the corrugated box 7 to the top of the lifting plate 42 through the transport line 41, and then starts the lifting cylinder 45 to lift the lifting plate 42, and then continues to start the movable cylinder 17 to drive the clamping parts at both ends of the movable circular cover plate 15 to move relatively close, until the resistance block touches the fins on the corrugated box 7, and then continues to move relatively, squeezing the resistance block to slide toward the inner cavity of the movable frame 183, and the edge of the movable groove 1831 of the movable frame 183 squeezes the bending rod 187 inward, and the fixed wedge block 1871 on the bending rod 187 clamps the fins on the corrugated box 7, and the end The bellows 7 is clamped, and even if the fixed wedge block 1871 pulls the bending rod 187 to continue bending while the bellows 7 is rotating, the bellows 7 will not be separated from the clamping piece. Due to the different spacings on different bellows 7, before touching the resistance block, it first collides with the guide cone 185. After the two groups of guide cones 185 first pass into the gap between the fins of the bellows 7, the first thrust spring 1833 is squeezed to drive the movable frame 183 to slide on the moving rod 1832, and the resistance block is correctly guided to the surface of the fin of the bellows 7, so as to achieve adaptation to the fins of the bellows 7 with different gaps.

[0052] After the clamping is completed, the driving roller 162 is started to drive the corrugated box 7 to slide to the center of the rust removal pipe 11, and the two ends of the rust removal pipe 11 are closed by the movable circular cover plate 15, and then the lifting cylinder 32 is started to slowly lift the leakage groove 13 to connect the leakage groove 13 on the rust removal pipe 11, and then the lifting cylinder 34 is started to slowly lift the push plate 131, and the friction material in the material receiving box 14 is slowly passed into the rust removal pipe 11, and at the same time, the driving motor 18 is started to flip the clamping part to flip the corrugated box 7. As the friction material gradually increases, the bending plate 1812 at the early stage moves the friction material to fall and hit the fins of the corrugated box 7, so that the rust is loosened. After that, when the friction material increases, it has a grinding effect. After the rust removal is completed, the rust material falls into the friction material, and the lifting cylinder 34 continues to descend, and the friction material falls into the material receiving box 14, so that the rust material can be collected. Then, the rotating motor 331 is started to rotate the rotating ring 31 until other material receiving boxes 14 are replaced to the bottom of the leakage groove 13, and the friction material is updated;

[0053] When the friction material in the material receiving box 14 needs to be removed, the lifting cylinder 32 is started to vibrate up and down. Since the rust material is fine and broken, it is very easy to fall under the material receiving box 14. A grid or hole is provided in the middle of the push plate 131, and then it flows out through the grid or hole on the push plate 131.

[0054] Since there are clamping mechanisms on both sides of the bellows 7, if there is concern about poor treatment effect, start the clamping part and move it to the top of the lifting plate 42. After the lifting plate 42 is lifted up by the lifting cylinder 45 to abut against the bottom surface of the bellows 7, the clamping part releases the clamping and starts the lifting cylinder 45 to descend. During the descent of the lifting cylinder 45, the abutment area of ​​the movable tooth 4221 is converted from the linear guide rail 4211 to the rotating guide rail 4212, driving the lifting plate 42 to rotate during the descent, completing the direction change on the lifting plate 42, and continuing to repeat the above operations can realize the change of different clamping surfaces to meet the rust removal needs.

[0055] After rust removal is completed, the driving roller 162 is started to slide the movable circular cover plate 15 to move the corrugated box 7 to the middle of the oil removal pipe 51. The movable circular cover plate 15 tightly buckles the two ends of the oil removal pipe 51, and then the water is pumped into the center of the oil removal pipe 51 through the liquid outlet pipe 55 in the water storage tank 53 until the water overflows from the oil removal pipe opening 52. The rotating driving motor 18 drives the corrugated box 7 to rotate, and the fat-soluble cleaning material in the water flow removes the grease on the corrugated box 7 and agglomerates, drifts above the water surface, and flows out through the oil removal pipe opening 52 for removal until no agglomerates flow out. Then, the solenoid valve 551 is started to make the remaining water in the movable circular cover plate 15 fall into the water storage tank 53 to complete the recovery. After that, the driving roller 162 can be started to drive it to the relevant transportation line 41 through the sliding guide rail 161 to complete the rust removal and cleaning of the corrugated box 7. At the same time, the rust removal and cleaning can be performed in the opposite order, depending on the actual situation.
