The inclined shape of the bottom of the first latch 25 is squeezed and matched with the circular holes on the side of the guide frame 2 that are away from each other. When the sliding frame 24 is pulled downward, the number of corrugated paper discharged can be quickly adjusted according to different needs, thereby meeting diversified production requirements, enhancing the adaptability and flexibility of the production line, and when the sliding frame 24 is pulled to adjust the spacing, it can adapt to corrugated paper of different sizes and specifications, thereby improving the versatility and flexibility of the equipment.

[0040] refer to Fig. 9 and Fig.10As shown, a feeding device for corrugated cardboard production, the outer surface of the output end of the multi-section electric push rod 110 is fixedly connected with a lower pressing frame 3, the output end of the multi-section electric push rod 110 is used to drive the lower pressing frame 3 to move up and down, the outer surfaces of both ends of the lower pressing frame 3 are slidably connected with third guide members 31, the lower pressing frame 3 is used to drive the third guide member 31 to move toward the side close to each other, the adjacent side of the bottom of the third guide member 31 is fixedly connected to the front and rear ends of the guide member 192, the third guide member 31 is used to drive the guide member 192 to move at the same time when moving, the guide member 192 is used to drive the first telescopic member 19 to move at the same time, the inner side of the third guide member 31 is fixedly connected with a reset spring 32, The tops of the two return springs 32 on the left are fixedly connected to the bottoms of the two ends of the left lower pressure frame 3, and the tops of the two return springs 32 on the right are fixedly connected to the bottoms of the two ends of the right lower pressure frame 3.

When the third guide member 31 is squeezed by the lower pressure frame 3, the first telescopic member 19 can be moved toward the side close to each other to center the corrugated paper, so that the corrugated paper can maintain a stable arrangement during the discharge process, avoiding production interruption or adjustment time caused by the displacement of the corrugated paper position, which helps to optimize the production process and improve the discharge efficiency.

[0041] refer to Fig.11 and Fig.12 As shown, a feeding device for corrugated cardboard production, the upper surface of the support member 15 is symmetrically slidably connected with four fixing members 4, the support member 15 is used to drive the fixing members 4 to move simultaneously, the bottom of the fixing members 4 is rotatably connected with a plurality of rollers 41, the front and rear adjacent ends of the fixing members 4 are slidably connected with second latches 42, the second latches 42 are used to limit the fixing members 4, the upper surface of the support member 15 is symmetrically provided with a plurality of circular holes, the bottom ends of the second latches 42 are snap-fitted with the circular holes provided on the upper surface of the support member 15, the outer surfaces of the left and right sides of the second guide member 14 are fixedly sleeved with four linear springs 43, The top of the left linear spring 43 is fixedly connected to the left side of the transport vehicle 13, and the top of the right linear spring 43 is fixedly connected to the right side of the transport vehicle 13. The linear spring 43 is used to drive the second guide member 14 to reset and move. When the roller 41 is driven to move by the fixing member 4, the outer surface of the roller 41 can be adapted to dock with processing equipment at different heights, so that the corrugated paper on the upper surface of the belt 16 can flow smoothly between different production lines, and the belt 16 can use different heights to easily cope with the feeding of corrugated paper on different production lines, thereby improving the flexibility and response speed of the production line.

[0042] The complete working principle and steps of the above embodiment are as follows:

[0043] refer to Figures 1 to 5As shown, when the feeding device is in the initial state, the guide frame 17 is in the closed state, and the first telescopic member 19 and the multi-section electric push rod 110 are in the extended state;

[0044] When using the feeding equipment to feed corrugated paper, the stacked corrugated paper can first be placed on the upper surface of the belt 16. At this time, the multi-section electric push rod 110 is started, so that the output end of the multi-section electric push rod 110 will drive the guide rod 112 to move downward. When the guide rod 112 moves downward, it can squeeze the top of the moving end of the first telescopic member 19 and prompt the moving end of the first telescopic member 19 to move downward. When the moving end of the first telescopic member 19 moves downward, it will drive the elastic belt 111 to move at the same time. When the elastic belt 111 moves downward, the lower surface of the elastic belt 111 can tightly fit the outer surface of the corrugated paper, so that when the transport vehicle 13 drives the belt 16 to move through the second guide member 14 and the support member 15, the displacement of the corrugated paper during the feeding process can be effectively limited, so that the corrugated paper can move steadily along the predetermined path and speed, reducing deviations and errors caused by displacement.

[0045] When the corrugated paper to be fed is relatively small, the guide frame 17 can be started to drive the sliding member 18 to move to the front and rear sides close to each other. When the sliding member 18 moves, it will drive the multi-section electric push rod 110 to move at the same time, and when the multi-section electric push rod 110 moves, it will drive the first telescopic member 19 to move at the same time. When the first telescopic member 19 moves on the outer surface of the guide rod 112, it will drive the elastic belt 111 to move at the same time, thereby reducing the distance between the elastic belts 111 on the side close to each other, so that the elastic belt 111 can adapt to smaller corrugated paper for limiting, thereby enhancing the versatility and compatibility of the equipment.

[0046] When the feeding of the corrugated paper is completed, the output end of the multi-section electric push rod 110 will drive the guide rod 112 to move upward. When the guide rod 112 moves upward, it will drive the moving end of the first telescopic member 19 to move at the same time. When the moving end of the first telescopic member 19 moves upward, it will drive the elastic belt 111 to move at the same time. When the elastic belt 111 moves upward, it will be separated from the outer surface of the corrugated paper, thereby facilitating the removal of the corrugated paper.

[0047] refer to Figures 6 to 8 As shown, when the feeding device is in the initial state, the blocking cloth 21 is in a contracted state, and the torsion spring 22 and the force storage spring 26 are in a naturally relaxed state;

[0048] When it is necessary to adjust the number of corrugated papers taken out from the upper surface of the belt 16, the staff can pull the sliding frame 24 downward. When the sliding frame 24 moves downward, the first latch 25 will be driven to move at the same time. When the first latch 25 moves downward, the inclined surface of the first latch 25 will be squeezed by the circular hole on the side away from each other of the guide frame 2, prompting the first latch 25 to move to the side away from each other. When the first latch 25 moves, the storage spring 26 will be moved to a stretched state. As the sliding frame 24 moves downward, the bottom of the blocking cloth 21 will be driven to move at the same time. When the bottom of the blocking cloth 21 moves downward, the top of the blocking cloth 21 will be pulled out on the outer surface of the rotating shaft 23. When the top of the rotating shaft 23 is pulled out on the outer surface of the blocking cloth 21, it will drive the blocking cloth 21 to rotate. As the blocking cloth 21 rotates, it will drive the torsion spring 22 to rotate to the storage state. When the first After the side of a latch 25 that is close to each other is aligned with the circular hole on the side of the guide frame 2 that is away from each other, the force storage spring 26 in a stretched state will drive the first latch 25 to slide toward the side that is close to each other. At this time, the side of the first latch 25 that is close to each other will be clamped in the circular hole on the side of the guide frame 2 that is away from each other, thereby preventing the sliding frame 24 from sliding. After the sliding frame 24 drives the blocking cloth 21 to unfold, the rear side of the blocking cloth 21 can block the corrugated paper on the top, and the belt 16 can drive the corrugated paper at the bottom to be discharged forward, so that the height of the sliding frame 24 can be adjusted to quickly adjust the number of corrugated paper discharged according to different needs, thereby meeting diversified production requirements, enhancing the adaptability and flexibility of the production line, and when the sliding frame 24 is pulled to adjust the spacing, it can adapt to corrugated paper of different sizes and specifications, thereby improving the versatility and flexibility of the equipment.

[0049] When the corrugated paper needs to be discharged all at once, the staff pulls the side of the first pins 25 that are away from each other, so that the side of the first pins 25 that are close to each other disengages from the circular hole on the side of the guide frame 2 that is away from each other. At this time, the torsion spring 22 in the force storage state can drive the rotating shaft 23 to rotate in the opposite direction. When the rotating shaft 23 rotates in the opposite direction, the top of the blocking cloth 21 can be rolled up. At this time, the bottom of the blocking cloth 21 can drive the sliding frame 24 to move upward, thereby increasing the distance between the sliding frame 24 and the belt 16, so that the corrugated paper can be taken out from the upper surface of the belt 16 at one time.

[0050] refer to Fig. 9 and Fig.10As shown, as the output end of the multi-section electric push rod 110 moves downward, it will drive the lower pressure frame 3 to move at the same time, and the lower pressure frame 3 can squeeze the top of the reset spring 32 when it moves downward. When the top of the reset spring 32 is squeezed, the bottom of the reset spring 32 will drive the third guide member 31 to move toward the side close to each other. When the third guide member 31 moves, it can drive the guide member 192 to move at the same time, and when the guide member 192 moves toward the side close to each other, it will drive the first telescopic member 19 to move at the same time. When the first telescopic member 19 moves, it will bring the moving end of the second telescopic member 191 to the expanded state, and when the first telescopic member 19 moves toward the side close to each other, it can fit the outer surface of the corrugated paper and push the corrugated paper to the center position of the upper surface of the belt 16, so that the corrugated paper can maintain a stable arrangement during the discharge process, avoiding production interruption or adjustment time caused by the position offset of the corrugated paper, which helps to optimize the production process and improve the discharge efficiency.

[0051] As the corrugated paper is discharged from the upper surface of the belt 16, the output end of the multi-section electric push rod 110 will drive the lower pressure frame 3 to move upward. When the lower pressure frame 3 moves upward, it will prompt the return spring 32 to move to a relaxed state, and when the lower pressure frame 3 moves, it can also squeeze the inner side of the third guide member 31, so that the third guide member 31 moves to the side away from each other. When the third guide member 31 moves, it will drive the first telescopic member 19 to move at the same time through the guide member 192. When the first telescopic member 19 moves to the side away from each other, it will prompt the second telescopic member 191 to move back to a contracted state. As the first telescopic member 19 moves to one side away from each other, the corrugated paper can be conveniently placed on the upper surface of the belt 16.

[0052] refer to Fig.10 and Fig.11 As shown, when the support member 15 needs to be docked with a higher processing equipment, the staff can push the transport vehicle 13, and the transport vehicle 13 will drive the fixing member 4 to move at the same time through the second guide member 14, and as the fixing member 4 moves, it will drive the roller 41 to move at the same time. At this time, the bottom of the roller 41 can be placed on the upper surface of the processing equipment, and as the fixing member 4 drives the roller 41 to continue to push, the roller 41 will drive the fixing member 4 to move upward, and when the fixing member 4 moves upward, it will drive the second guide member 14 to move at the same time. When the second guide member 14 moves upward, it will prompt the linear spring 43 to move to a compressed state, and when the second guide member 14 moves upward, it will drive the belt 16 to move at the same time through the support member 15. At this time, the upper surface of the belt 16 can be kept parallel to the processing equipment, so that it can be suitable for docking with processing equipment of different heights, so that the corrugated paper on the upper surface of the belt 16 can flow smoothly between different production lines.

[0053] When the corrugated paper feeding is completed, the staff can push the transport vehicle 13 in the opposite direction. When the transport vehicle 13 is pushed, the fixing member 4 will be driven to move at the same time through the second guide member 14. When the fixing member 4 moves, it will drive the roller 41 to move at the same time, so that the lower surface of the roller 41 is out of contact with the processing equipment. At this time, the linear spring 43 in a compressed state will move downward by driving the support member 15 through the second guide member 14. When the support member 15 moves downward, it will drive the belt 16 to move at the same time, so that the belt 16 returns to its initial state.

[0054] When it is necessary to dock a narrower device, the staff can pull up the second pin 42 so that the bottom of the second pin 42 is disengaged from the circular hole on the upper surface of the support 15, so that the fixing member 4 can be pushed left and right on the upper surface of the support 15 to change the width between the fixing members 4 so that the width between the fixing members 4 can adapt to the processing equipment. When the fixing members 4 are adjusted, the staff can press the second pin 42 downward so that the bottom of the second pin 42 is re-engaged in the circular hole on the upper surface of the support 15, thereby fixing the fixing member 4 to prevent the fixing member 4 from sliding. At this time, the staff can push the transport vehicle 13 so that the fixing members 4 can be docked with the narrower processing equipment, thereby increasing the flexibility of docking.

[0055] Although the present disclosure has been shown and described with reference to specific exemplary embodiments of the present disclosure, it should be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents. Therefore, the scope of the present disclosure should not be limited to the above-mentioned embodiments, but should be determined not only by the appended claims, but also by the equivalents of the appended claims.
