Description

Technical Field

[0001] This invention relates to the field of corrugated cardboard feeding devices, specifically a feeding device for corrugated cardboard production. Background Technology

[0002] Corrugated cardboard, as an important packaging material, is widely used in industrial production. In the production process of corrugated cardboard, feeding devices are usually used to continuously transport the corrugated paper to each processing stage to maintain the continuous and efficient operation of the production line. This not only reduces the tediousness of manual handling, but also improves the transportation efficiency of corrugated paper.

[0003] Currently, patent publication number "CN217229099U" discloses a cardboard transfer vehicle. After being driven to a designated position by a drive component, the vehicle-mounted conveyor component is rotated by a steering component, thereby docking the onboard conveyor component with a conveyor belt within a designated area. This allows cardboard boxes or cardboard to be moved onto the conveyor belt within the designated area, enabling the cardboard transfer vehicle to transfer cardboard or cardboard boxes from one area to multiple different areas. However, after practical use and comparison with existing technologies, the following drawbacks still exist:

[0004] During the transfer of corrugated paper by the feeding device, the speed of the push can easily cause the corrugated paper to move and become misaligned. This requires workers to spend extra time and effort to adjust the position of the corrugated paper, increasing the complexity of the operation and reducing the transfer efficiency. Furthermore, the corrugated paper is prone to collisions during displacement, resulting in scratches or dents that affect its appearance.

[0005] Therefore, the present invention proposes a feeding device for corrugated cardboard production to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0006] In view of the deficiencies of the existing technology, the present invention provides a feeding device for corrugated cardboard production, which can effectively solve the above-mentioned technical problems.

Guide rods are slidably connected to the outer surfaces of the tops of the multiple electric push rods. The outer surfaces of the two ends of one guide rod are slidably connected to the tops of one first telescopic member. The outer surfaces of the two ends of the guide rod on the other side are slidably connected to the tops of the other first telescopic member.

[0008] More preferably, one of the guide members is slidably connected between one end of the first telescopic member on one side, and another guide member is slidably connected between one end of the first telescopic member on the other side.

[0009] More preferably, a guide frame is symmetrically fixedly connected to the upper surface of one side of the support member, and a rotating shaft is rotatably connected to one side of the top of each guide frame. A barrier cloth is fixedly wrapped around the outer surface of each rotating shaft, and a sliding frame is fixedly connected to one end of each barrier cloth. The two ends of the sliding frame are slidably connected to the inner side of the guide frame, and a first pin is slidably connected to both ends of the sliding frame. The two first pins are in opposite directions. Multiple round holes are opened in a straight line on the side of the guide frame that is far apart from each other. The round holes on the side of the guide frame that is far apart from each other are engaged with the side of the first pins that are close to each other.

[0010] More preferably, torsion springs are fixedly sleeved on the outer surfaces of the rotating shafts at opposite ends, and the ends of the torsion springs that are close to each other are fixedly connected to the opposite side of the top of the guide frame. Storage springs are fixedly sleeved on the outer surfaces of the first pins at opposite ends, and the ends of the storage springs that are close to each other are fixedly connected to both ends of the sliding frame.

[0011] More preferably, the lower surfaces of the first pins at their closest points are symmetrically inclined, and the inclined shape of the bottom of the first pins is press-fitted with the circular holes opened on the opposite side of the guide frame.

[0012] More preferably, the outer surface of the output end of the multi-section electric push rod is fixedly connected to a lower pressure frame, and the outer surfaces of both ends of the lower pressure frame are slidably connected to a third guide member, with the bottom adjacent sides of the third guide member fixedly connected to both ends of the guide member.

[0013] More preferably, the outer surfaces at both ends of the lower pressure frame are pressed together with the inner side of the third guide member.

[0014] More preferably, the inner side of the third guide member is fixedly connected with a return spring, wherein the top of the two return springs on one side is fixedly connected to the bottom of both ends of the lower pressure frame on one side, and the top of the two return springs on the other side is fixedly connected to the bottom of both ends of the lower pressure frame on the other side.

[0015] More preferably, the upper surface of the support member is symmetrically slidably connected with multiple fixing members, the bottom of each fixing member is rotatably connected with multiple rollers, and each adjacent end of the fixing member is slidably connected with a second pin.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. When the guide rod moves downward by multiple electric push rods, the elastic band can tightly fit the outer surface of the corrugated paper, effectively limiting the displacement of the corrugated paper during the feeding process. This allows the corrugated paper to move steadily along a predetermined path and speed, reducing deviations and errors caused by displacement. Furthermore, restricting the corrugated paper can reduce collisions with its surroundings and lower the risk of damage.

[0019] 2. When the sliding frame is pulled down, the number of corrugated paper sheets discharged can be quickly adjusted according to different needs, thereby meeting diverse production requirements, enhancing the adaptability and flexibility of the production line, and adjusting the spacing by pulling the sliding frame can accommodate corrugated paper sheets of different sizes and specifications, thus improving the versatility and flexibility of the equipment.

[0020] 3. When the third guide member is squeezed by the lower pressure frame, the first telescopic member can move to the side that is closer to each other to center and limit the corrugated paper. This can keep the corrugated paper in a stable arrangement during the discharge process, avoid production interruption or adjustment time caused by the position of the corrugated paper, help optimize the production process, improve discharge efficiency, and the center discharge of corrugated paper can improve the accuracy and consistency of subsequent processing steps and ensure product quality.

[0021] 4. When the roller is moved by the fixing component, the outer surface of the roller can be connected to processing equipment of different heights, so that the corrugated paper on the upper surface of the belt can flow smoothly between different production lines. The belt can easily handle the feeding of corrugated paper from different production lines by using different heights, which improves the flexibility and response speed of the production line.

[0036] The present invention will be further described below with reference to embodiments.

[0037] Embodiments of the present invention

[0038] refer to Figures 1 to 5As shown, a feeding device for corrugated cardboard production includes a slide rail 1. First guide members 11 are slidably connected to the upper surfaces of both sides of the slide rail 1, and the first guide members 11 slide on the upper surfaces of both ends of the slide rail 1. A transport vehicle 13 is slidably connected between the outer surfaces of the top of the first guide members 11, and the first guide members 11 drive the transport vehicle 13 to move simultaneously. Compression springs 12 are fixedly connected to the upper surfaces of both sides of the first guide members 11, and the tops of the compression springs 12 are fixedly connected to the lower surfaces of the left and right sides of the transport vehicle 13, reducing the swaying amplitude of the transport vehicle 13 during movement. Second guide members 14 are slidably connected between the outer surfaces of the left and right sides of the transport vehicle 13, and the transport vehicle 13 drives the second guide members 14 to move simultaneously. A support member 15 is rotatably connected to the upper surface of the second guide member 14. The second guide member 14 drives the support member 15 to move simultaneously. The support member 15 is used to adjust the transport angle on the upper surface of the second guide member 14. A belt 16 is rotatably connected to the upper surface of the support member 15. The support member 15 drives the belt 16 to rotate simultaneously. The belt 16 is used to transport corrugated paper. Guide frames 17 are fixedly connected to both sides of the support member 15. Sliding members 18 are slidably connected to both ends of the two guide frames 17. The guide frames 17 drive the sliding members 18 to slide back and forth. Second telescopic members 191 are fixedly connected to the sides of the sliding members 18 that are far apart from each other. The sliding members 18 drive the second telescopic members 191 to move simultaneously. The movement of the second telescopic members 191... Each of the moving ends is fixedly connected to a first telescopic member 19. A second telescopic member 191 is used to drive the first telescopic member 19 to move simultaneously. One guide member 192 is slidably connected between the right ends of the left first telescopic member 19, and another guide member 192 is slidably connected between the left ends of the right first telescopic member 19. The side of the guide members 192 that is close to each other is used to limit the corrugated paper. Multiple electric push rods 110 are fixedly connected to the side of the guide frame 17 that is far apart from each other. Guide rods 112 are slidably connected to the outer surface of the top of the multiple electric push rods 110. The moving end of the multiple electric push rods 110 is used to drive the guide rods 112 to move up and down. The outer surfaces of the two ends of the left guide rod 112 are slidably connected between the tops of the left first telescopic member 19, and the right guide rod 112 is slidably connected to the top of the right first telescopic member 19. The outer surfaces of both ends of the rod 112 are slidably connected to the top of the first telescopic member 19 on the right side. When the guide rod 112 moves up and down, it drives the moving end of the first telescopic member 19 to move simultaneously. An elastic band 111 is slidably connected between the tops of the first telescopic members 19 on the left and right sides, close to each other. The moving end of the first telescopic member 19 drives the elastic band 111 to move simultaneously. The lower surface of the elastic band 111 is used to limit the corrugated paper. When the guide rod 112 moves downward by the multi-section electric push rod 110, the elastic band 111 can tightly fit the outer surface of the corrugated paper, effectively limiting the displacement of the corrugated paper during the feeding process, so that the corrugated paper can move forward stably according to the predetermined path and speed, reducing deviations and errors caused by displacement.

[0039] refer to Figures 6 to 8 As shown, a feeding device for corrugated cardboard production includes a guide frame 2 symmetrically fixedly connected to the upper surface of the front side of a support member 15. A rotating shaft 23 is rotatably connected to the rear side of the top of each guide frame 2. A blocking cloth 21 is fixedly wound around the outer surface of each rotating shaft 23. When the blocking cloth 21 is pulled, it drives the rotating shaft 23 to rotate, thus blocking the corrugated cardboard. A torsion spring 22 is fixedly sleeved on the outer surface of each rotating shaft 23 at opposite ends. The ends of the torsion springs 22 that are close to each other are fixedly connected to the opposite side of the rear end of the top of the guide frame 2. The torsion spring 22 drives the rotating shaft 23 to return to its original rotation. A sliding frame 24 is fixedly connected between the bottom ends of the blocking cloth 21. The two ends of the sliding frame 24 are slidably connected between the inner sides of the guide frame 2. The sliding frame 24 drives the bottom ends of the blocking cloth 21 downwards. First pins 25 are slidably connected to both ends of the sliding frame 24, with the two first pins 25 in opposite directions. The sliding frame 24 drives the first pins 25 simultaneously... The guide frame 2 has multiple circular holes on its opposite sides, which are arranged in a straight line. These holes engage with the adjacent sides of the first pin 25. The circular holes restrict the movement of the first pin 25. A storage spring 26 is fixedly fitted onto the outer surface of the opposite side of the first pin 25. The adjacent ends of the storage springs 26 are fixedly connected to both ends of the sliding frame 24. The storage springs 26 are used to drive the first pin 25 to reset. The lower surfaces of the adjacent ends of the first pin 25 are symmetrically inclined. The inclined bottom of the first pin 25 engages with the circular holes on the opposite side of the guide frame 2. When the sliding frame 24 is pulled downwards, the number of corrugated sheets discharged can be quickly adjusted according to different needs, thereby meeting diverse production requirements, enhancing the adaptability and flexibility of the production line, and adapting to different sizes and specifications of corrugated sheets when the spacing is adjusted by pulling the sliding frame 24, improving the versatility and flexibility of the equipment.

[0040] refer to Figure 9 and Figure 10As shown, a feeding device for corrugated cardboard production includes a lower pressure frame 3 fixedly connected to the outer surface of the output end of a multi-section electric push rod 110. The output end of the multi-section electric push rod 110 drives the lower pressure frame 3 to move up and down. A third guide member 31 is slidably connected to the outer surface of both ends of the lower pressure frame 3. The lower pressure frame 3 drives the third guide member 31 to move towards each other. The bottom adjacent sides of the third guide member 31 are fixedly connected to the front and rear ends of a guide member 192. When the third guide member 31 moves, it drives the guide member 192 to move simultaneously. The guide member 192 drives the first telescopic member 19 to move simultaneously. A return spring 32 is fixedly connected to the inner side of each third guide member 31. The tops of the two return springs 32 on the left are fixedly connected to the bottoms of both 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 both ends of the right lower pressure frame 3. The lower pressure frame 3 is used to squeeze the return springs 32, and the return springs 32 are used to drive the third guide member 31 to move further towards each other. When the lower pressure frame 3 squeezes the third guide member 31, the first telescopic member 19 can move towards each other to center and limit the corrugated paper. This can keep the corrugated paper in a stable arrangement during the discharge process, avoid production interruption or adjustment time caused by the position deviation of the corrugated paper, help optimize the production process and improve discharge efficiency.

[0041] refer to Figure 11 and Figure 12 As shown, a feeding device for corrugated cardboard production includes a support member 15 with four fixed members 4 symmetrically slidably connected to its upper surface. The support member 15 drives the fixed members 4 to move simultaneously. Multiple rollers 41 are rotatably connected to the bottom of each fixed member 4. Second pins 42 are slidably connected to adjacent ends of each fixed member 4, limiting their movement. Multiple circular holes are symmetrically formed on the upper surface of the support member 15, and the bottom ends of the second pins 42 engage with these holes. Four linear springs 43 are fixedly sleeved on the outer surfaces of both sides of the second guide member 14. 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 14 to move back to its original position. When the roller 41 is moved by the fixing part 4, the outer surface of the roller 41 can be connected to 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. The belt 16 can easily handle the feeding of corrugated paper from different production lines using different heights, which improves the flexibility and response speed of the production line.

[0042] The complete working principle and steps of the above embodiments 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 this feeding device 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 activated, so that the output end of the multi-section electric push rod 110 drives 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 cause 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 simultaneously. 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. Thus, when the transport vehicle 13 drives the belt 16 to move through the second guide member 14 and the support member 15, it can effectively limit the displacement of the corrugated paper during the feeding process, 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 small, the guide frame 17 can be activated, causing the guide frame 17 to move the sliding member 18 to move forward and backward to the two sides that are close to each other. When the sliding member 18 moves, it will drive the multi-section electric push rod 110 to move simultaneously. When the multi-section electric push rod 110 moves, it will drive the first telescopic member 19 to move simultaneously. When the first telescopic member 19 moves on the outer surface of the guide rod 112, it will drive the elastic band 111 to move simultaneously, thereby reducing the distance between the elastic bands 111 on the side that are close to each other. This allows the elastic band 111 to adapt to the smaller corrugated paper for limiting, enhancing the versatility and compatibility of the equipment.

[0046] When the corrugated paper is finished being fed, 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 simultaneously. When the moving end of the first telescopic member 19 moves upward, it will drive the elastic band 111 to move simultaneously. When the elastic band 111 moves upward, it will disengage from the outer surface of the corrugated paper, thus 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 barrier cloth 21 is in a contracted state, and the torsion spring 22 and the energy storage spring 26 are in a naturally relaxed state.

[0048] When it is necessary to adjust the number of corrugated sheets removed from the upper surface of belt 16, the operator can pull the sliding frame 24 downwards. As the sliding frame 24 moves downwards, it will simultaneously move the first pin 25. When the first pin 25 moves downwards, its inclined surface will press against the circular hole on the opposite side of the guide frame 2, causing the first pin 25 to move towards the opposite side. The movement of the first pin 25 will move the storage spring 26 to a stretched state. As the sliding frame 24 moves downwards, it will simultaneously move the bottom of the barrier cloth 21. When the bottom of the barrier cloth 21 moves downwards, the top of the barrier cloth 21 will be pulled out from the outer surface of the rotating shaft 23. When the top of the rotating shaft 23 is pulled out from the outer surface of the barrier cloth 21, it will cause the barrier cloth 21 to rotate. As the barrier cloth 21 rotates, it will cause the torsion spring 22 to rotate to a stored state. When the first... After the first pin 25 is aligned with the circular holes on the opposite side of the guide frame 2, the tensioned spring 26 will cause the first pin 25 to slide towards the opposite side. At this time, the first pin 25 will be engaged in the circular holes on the opposite side of the guide frame 2, thus preventing the sliding frame 24 from sliding. After the sliding frame 24 drives the barrier cloth 21 to unfold, the rear side of the barrier cloth 21 can block the corrugated paper at the top, and the belt 16 can drive the corrugated paper at the bottom to be discharged forward. Thus, adjusting the height of the sliding frame 24 can quickly adjust the number of corrugated papers discharged according to different needs, thereby meeting diverse production requirements, enhancing the adaptability and flexibility of the production line, and adjusting the spacing of the sliding frame 24 can accommodate corrugated paper of different sizes and specifications, improving the versatility and flexibility of the equipment.

[0049] When all the corrugated paper needs to be discharged at once, the worker pulls the side of the first pin 25 that is far apart, so that the side of the first pin 25 that is close together disengages from the round hole on the side of the guide frame 2 that is far apart. At this time, the torsion spring 22, which is in a stored state, can drive the rotating shaft 23 to rotate in the opposite direction. When the rotating shaft 23 rotates in the opposite direction, it can roll up the top of the barrier cloth 21. At this time, the bottom of the barrier 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 once.

[0050] refer to Figure 9 and Figure 10As shown, when the output end of the multi-section electric push rod 110 moves downward, it drives the lower pressure frame 3 to move simultaneously. When the lower pressure frame 3 moves downward, it can compress the top of the return spring 32. When the top of the return spring 32 is compressed, the bottom of the return spring 32 will drive the third guide member 31 to move towards each other. When the third guide member 31 moves, it can drive the guide member 192 to move simultaneously. When the guide member 192 moves towards each other, it will drive the first telescopic member 19 to move simultaneously. When the first telescopic member 19 moves, it will drive the moving end of the second telescopic member 191 to the unfolded state. When the first telescopic member 19 moves towards each other, it can fit against the outer surface of the corrugated paper and push the corrugated paper to the center position on the upper surface of the belt 16. This can keep the corrugated paper in a stable arrangement during the discharge process, avoid production interruption or adjustment time caused by the position displacement of the corrugated paper, help optimize the production process and improve 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 drives the lower pressure frame 3 to move upward. When the lower pressure frame 3 moves upward, it causes the return spring 32 to move to a relaxed state. When the lower pressure frame 3 moves, it can also squeeze the inner side of the third guide member 31, causing the third guide member 31 to move to the side away from each other. When the third guide member 31 moves, it will drive the first telescopic member 19 to move simultaneously through the guide member 192. When the first telescopic member 19 moves to the side away from each other, it will cause the second telescopic member 191 to move back to the retracted state. As the first telescopic member 19 moves to the side away from each other, the corrugated paper can be easily placed on the upper surface of the belt 16.

[0052] refer to Figure 10 and Figure 11 As shown, when the support member 15 needs to be connected with a higher processing equipment, the operator can push the transport vehicle 13. The transport vehicle 13 will drive the fixing member 4 to move simultaneously through the second guide member 14. As the fixing member 4 moves, it will drive the roller 41 to move simultaneously. At this time, the bottom of the roller 41 can rest on the upper surface of the processing equipment. As the fixing member 4 drives the roller 41 to be pushed, the roller 41 will drive the fixing member 4 to move upward. When the fixing member 4 moves upward, it will drive the second guide member 14 to move simultaneously. When the second guide member 14 moves upward, it will cause the linear spring 43 to move to the compressed state. When the second guide member 14 moves upward, it will drive the belt 16 to move simultaneously 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 connected to processing equipment of different heights. This allows the corrugated paper on the upper surface of the belt 16 to flow smoothly between different production lines.

[0053] When the corrugated paper feeding is completed, the worker can push the transport vehicle 13 in the opposite direction. When the transport vehicle 13 is pushed, it will drive the fixing part 4 to move simultaneously through the second guide 14. When the fixing part 4 moves, it will drive the roller 41 to move simultaneously, so that the lower surface of the roller 41 is separated from the processing equipment. At this time, the linear spring 43, which is in a compressed state, will drive the support part 15 to move downward through the second guide 14. When the support part 15 moves downward, it will drive the belt 16 to move simultaneously, so that the belt 16 returns to its initial state.

[0054] When it is necessary to connect to narrower equipment, the operator can pull the second pin 42 upwards, causing the bottom of the second pin 42 to disengage from the round hole on the upper surface of the support member 15. This allows the fixing member 4 to be pushed left and right on the upper surface of the support member 15, changing the width between the fixing members 4 to accommodate the processing equipment. After the fixing members 4 are adjusted, the operator can press the second pin 42 downwards, causing the bottom of the second pin 42 to re-engage into the round hole on the upper surface of the support member 15, thereby fixing the fixing member 4 and preventing it from sliding.
