Description

Technical Field

[0001] This utility model relates to the field of paper stacking technology, and in particular to a paper feeding and stacking machine. Background Technology

[0002] In the packaging and printing industry, paper stacking is a crucial step in the production process. The use of paper stackers improves the efficiency and accuracy of paper handling, reduces the labor intensity of manual operations, and is particularly suitable for large-scale paper production and processing enterprises, ensuring the continuity and stability of production.

[0003] Currently, common paper feeding and stacking machines mainly consist of a conveying device and a stacking device. The conveying device typically uses a conveyor belt to transport the cardboard sheets one by one, while the stacking device uses a mechanical structure to stack the cardboard sheets into stacks. However, this traditional structure has some shortcomings. In actual operation, workers need to manually place the cardboard sheets onto the conveyor belt, which is not only inefficient but also prone to jamming or shifting during transport due to uneven placement, leading to cardboard blockage and seriously affecting production efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a paper feeding and stacking machine, which aims to improve the existing technology that requires manual placement of cardboard on the conveyor belt, which is not only inefficient but also causes jamming or deviation during the conveying process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paper feeding and stacking machine, comprising a conveying frame, a cylinder rotatably connected inside the conveying frame, an arrangement assembly provided on the outer wall of the cylinder, a lifting frame fixedly connected to one end of the conveying frame, a slider slidably connected inside the lifting frame, a lifting plate fixedly connected to the outer wall of the slider, a first conveyor belt fixedly connected to the outer wall of the feeding port above the lifting frame, an electrical box provided below the first conveyor belt, and a second conveyor belt fixedly connected to the side of the first conveyor belt away from the lifting frame.

[0006] Furthermore, the arrangement assembly includes a partition, which is slidably connected inside the conveying frame, and the outer wall of the partition is slidably connected to the outer wall of the cylinder.

[0007] Furthermore, a stacking frame is fixedly connected to the side of the second conveyor belt away from the first conveyor belt, and a second connecting plate is slidably connected to the upper surface of the stacking frame. A threaded rod is rotatably connected to the side of the second connecting plate away from the stacking frame.

[0008] Furthermore, a motor is fixedly connected inside the stacking rack, a rack is slidably connected to the outer wall of the motor output end, a bearing medium is slidably connected to the inner wall of the rack, and the threaded rod is threadedly connected to the outer wall of the bearing medium inside.

[0009] Furthermore, a fixed plate is fixedly connected to the side of the lifting frame away from the conveyor belt, and a push cylinder is fixedly connected inside the fixed plate.

[0010] Furthermore, a second push cylinder is fixedly connected above the lifting frame, a rotating block is provided at the output end of the second push cylinder, a connecting rod is fixedly connected to the outer wall of the rotating block, a connecting plate is fixedly connected to the lower surface of the connecting rod, and a push block is fixedly connected to the lower surface of the connecting plate.

[0011] Furthermore, a sensor is fixedly connected to the upper surface of the conveying frame, and a sensor is fixedly connected to the upper surface of the stacking rack.

[0012] Furthermore, a positioning rod is provided on the upper surface of the stacking rack, and a baffle is fixedly connected to the outer wall of the connecting plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by setting up a conveying frame, a cylinder and an arrangement component, stable paper conveying is achieved, effectively preventing blockage. The cylinder inside the conveying frame is rotatably connected, and its outer wall is provided with an arrangement component composed of partitions. When the paper is placed on the conveyor belt, the partitions can separate and arrange the paper, ensuring that each sheet of paper remains independent and orderly during the conveying process. This avoids jamming or shifting caused by mutual interference between sheets of paper, ensures the continuity of the paper loading and stacking process, and thus improves the overall production efficiency.

[0015] 2. In this utility model, the positioning rod on the upper surface of the stacking frame and the structure that drives the connecting plate 1 to move through the motor, rack, carrying medium and threaded rod achieve a better stacking effect. The motor drives the rack to move, and the carrying medium that is slidably connected to the rack drives the threaded rod to rotate, thereby enabling the connecting plate 1, which is rotatably connected to the threaded rod and cooperates with the positioning rod, to accurately adjust its position. During the stacking process, the paper arrives above the stacking frame under the conveyor belt 2. The connecting plate 1 and its connected baffle can accurately block and stack the paper according to the set position to ensure the neatness and stability of each stack of paper. The presence of the positioning rod provides precise guidance for the movement of the connecting plate 1. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 - Figure 4 This utility model provides an embodiment of a paper feeding and stacking machine, including a conveying frame 2, a cylinder 1 rotatably connected inside the conveying frame 2, an arrangement component provided on the outer wall of the cylinder 1, a lifting frame 3 fixedly connected to one end of the conveying frame 2, a slider 5 slidably connected inside the lifting frame 3, a lifting plate 6 fixedly connected to the outer wall of the slider 5, a first conveyor belt 7 fixedly connected to the outer wall of the feeding port above the lifting frame 3, an electrical box 11 provided below the first conveyor belt 7, and a second conveyor belt 8 fixedly connected to the side of the first conveyor belt 7 away from the lifting frame 3; the arrangement component includes... The system includes a partition 20, which is slidably connected inside the conveyor frame 2, and the outer wall of the partition 20 is slidably connected to the outer wall of the cylinder 1; a fixed plate 25 is fixedly connected to the upper side of the lifting frame 3 away from the conveyor belt 7, and a push cylinder 15 is fixedly connected inside the fixed plate 25; a push cylinder 28 is fixedly connected to the upper part of the lifting frame 3, and a rotating block 9 is provided at the output end of the push cylinder 28. A connecting rod 26 is fixedly connected to the outer wall of the rotating block 9, and a connecting plate 17 is fixedly connected to the lower surface of the connecting rod 26. A push block 4 is fixedly connected to the lower surface of the connecting plate 17.

[0024] Specifically, the conveyor frame 2 serves as the basic structure of the entire paper loading and stacking machine, providing support and installation positions for various internal components. The internally rotating cylinder 1 works in conjunction with the arrangement assembly to achieve orderly arrangement and conveying of the paper. During the rotation of the cylinder 1, the arrangement assembly on its outer wall can sort and separate the paper. The partition 20 in the arrangement assembly is slidably connected inside the conveyor frame 2 and its outer wall is slidably connected to the outer wall of the cylinder 1. When the cylinder 1 rotates, the partition 20 guides the paper placed on it, preventing the paper from sticking or stacking during conveying. The lifting frame 3, slider 5, and lifting plate 6: one end of the lifting frame 3 is fixedly connected to the conveyor frame 2, and its internally slidably connected... The slider 5 can move up and down within the frame. A lifting plate 6 is fixedly connected to the outer wall of the slider 5, enabling vertical lifting and lowering under the slider 5's influence. During paper conveying, the lifting plate 6 transitions the paper from the conveyor frame 2 to the conveyor belt 7. When the lifting plate 6 rises to a suitable height, it smoothly delivers the paper onto the conveyor belt 7, ensuring continuous paper conveying and preventing paper from falling or jamming due to height differences. The conveyor belt 7 is fixedly connected to the outer wall of the feeding port above the lifting frame 3. It primarily receives the paper from the lifting plate 6 and continues to convey the paper forward. The electrical box 11 located below the conveyor belt 7 provides power to the entire stacker. The second conveyor belt 8 is fixedly connected to the conveyor belt 7. Conveyor Belt 7, located away from the lifting frame 3, transports the paper from Conveyor Belt 7 to the stacking area. Conveyor Belt 8 extends the paper's transport path, ensuring accurate arrival at the stacking position. Its coordinated operation with Conveyor Belt 7 guarantees high efficiency and stability throughout the entire transport process. Fixed Plate 25 is fixedly connected to the lifting frame 3 on the side away from Conveyor Belt 7. Inside, a push cylinder 15 is fixedly connected, providing a pushing function. During paper transport, Push Cylinder 15 can extend or retract as needed. For example, when paper is waiting to be transported on Lifting Plate 6, Push Cylinder 15 can push the paper, allowing it to enter the transport range of Conveyor Belt 7 more smoothly, or when paper is on Conveyor Belt 7... When slight jamming occurs, push cylinder 15 can assist the paper to continue moving forward, ensuring smooth paper delivery. Push cylinder 2 18 is fixedly connected above the lifting frame 3. The rotating block 9 at its output end can rotate under the drive of push cylinder 2 18. The connecting rod 26 fixedly connected to the outer wall of the rotating block 9 changes angle as the rotating block 9 rotates, thereby driving the connecting plate 17 fixedly connected to the lower surface of the connecting rod 26 to move. The push block 4 fixedly connected to the lower surface of the connecting plate 17 can make precise position adjustments in the horizontal direction under the drive of the connecting plate 17. Through the cooperation of push block 4 and push cylinder 15, the paper can be accurately transported to the top of the conveyor belt 7 for transmission.

[0025] Reference Figure 1 - Figure 3A stacking frame 22 is fixedly connected to the side of conveyor belt 2 away from conveyor belt 7. A connecting plate 23 is slidably connected to the upper surface of the stacking frame 22. A threaded rod 12 is rotatably connected to the side of the connecting plate 23 away from the stacking frame 22. A motor 16 is fixedly connected inside the stacking frame 22. A rack 14 is slidably connected to the outer wall of the output end of the motor 16. A carrying medium 24 is slidably connected to the inner wall of the rack 14. The threaded rod 12 is threadedly connected to the outer wall of the carrying medium 24. A sensor 19 is fixedly connected to the upper surface of the conveyor frame 2. A sensor 21 is fixedly connected to the upper surface of the stacking frame 22. A positioning rod 13 is provided on the upper surface of the stacking frame 22. A baffle 10 is fixedly connected to the outer wall of the connecting plate 23.

[0026] Specifically, conveyor belt 28 transports the paper to the stacking rack 22, which is fixedly connected to it. The stacking rack 22 provides a working platform for subsequent stacking operations. Connecting plate 23, which is slidably connected to its surface, can slide laterally on the stacking rack 22 to adjust its position. The threaded rod 12, which is rotatably connected to the side of connecting plate 23 away from the stacking rack 22, rotates under the drive of motor 16, which is fixedly connected inside the stacking rack 22. The rack 14, which is slidably connected to the outer wall of the output end of motor 16, moves under the drive of motor 16. The carrying medium 24, which is slidably connected to the inner wall of rack 14, rotates with the movement of rack 14. Since the threaded rod 12 is threadedly connected to the inner wall of carrying medium 24, the rotation of carrying medium 24 will cause the threaded rod 12 to rotate, thereby driving connecting plate 23 to move laterally, accurately adjusting the position of baffle 10 to adapt to the stacking requirements of different sizes of paper and ensure that the paper can be accurately stacked. Sensor 19, which is fixedly connected to the upper surface of conveyor frame 2, is used to detect the position and status of the paper on conveyor frame 2. When the paper is placed or conveyed... If any abnormalities occur during the process, such as paper accumulation or jamming, sensor 19 can detect them in time and transmit the signal to the control system for timely handling, ensuring the normal operation of the conveying process. Sensor 21, which is fixedly connected to the upper surface of the stacking frame 22, mainly monitors the stacking of paper on the stacking frame 22. For example, when the paper stack reaches a certain height or the paper stacking position is inaccurate, sensor 21 will send a signal to control the relevant components to adjust, ensuring the accuracy and stability of the stacking. The positioning rod 13 set on the upper surface of the stacking frame 22 provides precise guidance for the movement of the connecting plate 23 and the baffle 10 connected to it, ensuring that the baffle 10 always maintains a straight line during the lateral movement, so that the baffle 10 can accurately block the paper and ensure that the paper is neatly arranged during the stacking process. The baffle 10, which is fixedly connected to the outer wall of the connecting plate 23, plays a key role in the stacking process. It can block the paper from moving forward and stack the paper in front of the baffle 10, so as to adapt to the stacking of paper of different sizes and ensure the neatness and stability of the paper stack.

[0027] Working Principle: First, the paper to be stacked is placed on the cylinder 1 inside the conveyor frame 2 via a conveyor device. The partition 20 on the outer wall of the cylinder 1 performs initial separation and sorting of the paper. At this time, the slider 5 inside the lifting frame 3 drives the lifting plate 6 to rise, lifting the paper to a position level with the first conveyor belt 7. Then, the pushing cylinder 15 inside the fixed plate 25 pushes the paper, allowing it to smoothly enter the first conveyor belt 7. During this process, the sensor 19 monitors the position and status of the paper on the conveyor frame 2 in real time. If any abnormality occurs, such as paper accumulation or jamming, it will promptly transmit a signal to the control system for appropriate handling. After the paper enters the first conveyor belt 7, the first conveyor belt 7 smoothly conveys the paper forward to the second conveyor belt 8. The second conveyor belt 8 continues to transport the paper to the top of the stacking rack 22. Throughout the entire conveying process, the stable operation of the first conveyor belt 7 and the second conveyor belt 8 ensures the uniform movement of the paper and reduces the possibility of paper deviation. When the paper reaches the stacking rack 22... At the same time, the sensor 21 on the upper surface of the stacking frame 22 monitors the stacking status of the paper. The motor 16 inside the stacking frame 22 starts, and the rack 14 slidably connected to the outer wall of the output end of the motor 16 begins to move. The carrying medium 24 slidably connected to the inner wall of the rack 14 will rotate along with it. Since the outer wall of the threaded rod 12 is threadedly connected to the inside of the carrying medium 24, the rotation of the carrying medium 24 causes the threaded rod 12 to rotate, thereby driving the connecting plate 23, which is rotatably connected to the threaded rod 12 and cooperates with the positioning rod 13, to move laterally and precisely adjust the position of the baffle 10. The baffle 10 blocks the paper from moving forward and stacks the paper in front of the baffle 10. At the same time, the push cylinder 18 above the lifting frame 3 can drive the rotating block 9 to rotate as needed. Through the connecting rod 26, the connecting plate 17 and the push block 4 connected to it move, which assists in the positioning and stacking of the paper during the stacking process, ensuring the neatness and stability of each stack of paper and adapting to the stacking requirements of different sizes of paper.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
