Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper processing technology, and in particular to a high-speed cored roll paper rewinding machine. Background Technology
[0002] In today's papermaking and paper product processing industry, with the increasing market demand for roll paper and increasingly stringent requirements for product quality, high-speed cored roll paper rewinders have become key equipment for improving production efficiency and ensuring product quality. They can slit large rolls of paper into smaller rolls to meet the needs of different usage scenarios, playing a vital role in the production of toilet paper, packaging paper, and other products. Their performance directly affects the production efficiency and quality of paper products.
[0003] Early roll paper rewinding machines primarily employed simple transmission mechanisms, using a motor to drive the roll and rewind the paper. Their technical principles were largely based on basic mechanical transmission principles, utilizing gear and belt drives to transmit power, lacking precise control over the complexities of the paper rewinding process. During rewinding, adjustments were made solely based on the operator's experience, lacking effective monitoring and adjustment methods for key parameters such as paper feed speed and tension.
[0004] However, traditional rewinding machines have some problems. During high-speed rewinding, the paper is prone to shifting due to uneven paper quality, minor vibrations in the conveying components, and various unstable factors during equipment operation. Once the paper shifts, the rewound roll will have uneven tension, uneven edges, and may even wrinkle and break. This leads to a large number of defective products, increases production costs, reduces product competitiveness in the market, makes it difficult to meet customer demand for high-quality roll paper, and seriously restricts the development of the paper processing industry. Therefore, a heating device for preparing glass fire retardant liquid is proposed to solve these problems. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-speed cored roll paper rewinding machine, including a housing, a support frame fixedly connected to the outer wall of the housing, a correction component arranged above the support frame, a conveying and collecting component arranged on the inner wall of the support frame, and an automatic lifting rod component arranged on the outer wall of the housing;
[0007] The correction assembly includes a correction roller, which is disposed above a support frame. A detector is fixedly connected to the upper surface of the support frame. A support rod is fixedly connected to the outer wall of the support frame. A hydraulic rod is fixedly connected to the upper surface of the support rod. A moving block is fixedly connected to the output end of the hydraulic rod. A slider is fixedly connected to the lower surface of the moving block. A sliding column is fixedly connected to the lower surface of the support rod. A rotating shaft is rotatably connected to the inner wall of the moving block. A connecting column is fixedly connected to the outer wall of the rotating shaft.
[0008] Optionally, the automatic lifting rod assembly includes a rotating rod, the inner wall of which is rotatably connected to the outer wall of the housing, a second rotating column fixedly connected to the outer wall of the rotating rod, a cylinder fixedly connected to the outer wall of the housing, a first rotating column fixedly connected to the output end of the cylinder, and a connecting plate fixedly connected to the outer wall of the first rotating column.
[0009] Optionally, the conveying and collecting assembly includes a placement roller, both ends of which are rotatably connected to the inner wall of the support frame. A motor is fixedly connected to the upper side of the outer wall of the outer shell, and a gear is fixedly connected to the output end of the motor. A rotating shaft is rotatably connected to the inner wall of the outer shell, and a gear is fixedly connected to one end of the rotating shaft. The tooth ends of the gear and gear are meshed. A rotating shaft is fixedly connected to the outer wall of the gear. A conveying roller is fixedly connected to one end of the rotating shaft, and a tension roller is fixedly connected to the other end of the rotating shaft. A motor is fixedly connected to the lower side of the outer wall of the outer shell, and a collecting roller is fixedly connected to the output end of the motor.
[0010] Optionally, the outer wall of the collecting roller is rotatably connected to the inner wall of the rotating rod, and the rotating rod is used to facilitate the handling of the processed roll of paper.
[0011] Optionally, the outer wall of the conveying roller is disposed on the inner wall of the housing, and the conveying roller is used to convey paper.

[0015] The high-speed cored roll paper rewinder provided in this embodiment of the utility model has at least one of the following technical effects:
[0016] 1. In this utility model, the paper position is monitored in real time by a detector. When the paper position deviates, the signal is transmitted to the hydraulic rod, which pushes the moving block to move. The moving block drives the slider to slide on the sliding column to maintain stability. The connecting column drives the correction roller to adjust the position and correct the paper deviation. This solves the problem that the paper is prone to deviation during rewinding. Paper deviation will lead to uneven tightness of the finished product, uneven edges, wrinkles and breakage, which will affect the quality. It achieves the goals of preventing deviation, improving rewinding accuracy, reducing the defect rate, reducing costs, and improving product competitiveness and production efficiency.
[0017] 2. In this utility model, the rotating column at the output end of the cylinder drives the connecting plate to move. The connecting plate drives the rotating rod to rotate around the outer side of the outer shell. Since the collecting roller rotates inside the rotating rod, the position of the rotating rod changes when it rotates, making it convenient for the operator to pick up the processed roll of paper. This achieves the effect of making it convenient for the operator to quickly and easily pick up the roll of paper, improving work efficiency, and optimizing the operation process.

[0030] Reference Figure 1 and Figure 3An embodiment of this utility model is provided: a high-speed cored roll paper rewinding machine, including a housing 1, a support frame 2 fixedly connected to the outer wall of the housing 1, a deviation correction component provided above the support frame 2 to prevent paper deviation, a conveying and collecting component provided on the inner wall of the support frame 2 to convey and collect paper, and an automatic lifting rod component provided on the outer wall of the housing 1 for convenient handling by workers.
[0031] The correction assembly includes a correction roller 26, which is positioned above the support frame 2 to correct any misaligned paper and ensure that the paper remains in the correct position during rewinding. A detector 14 is fixedly connected to the upper surface of the support frame 2 to monitor the paper position in real time. Once a paper misalignment is detected, a signal is promptly transmitted to the hydraulic rod 11. A support rod 10 is fixedly connected to the outer wall of the support frame 2, and a hydraulic rod 11 is fixedly connected to the upper surface of the support rod 10. A moving block 19 is fixedly connected to the output end of the hydraulic rod 11. After receiving the signal from the detector 14, the moving block 19 is pushed to move. A slider 20 is fixedly connected to the lower surface of the moving block 19, which cooperates with the sliding column 21 to ensure the stability of the moving block 19 during movement. A rotating shaft 18 is rotatably connected to the inner wall of the moving block 19, and a connecting column 17 is fixedly connected to the outer wall of the rotating shaft 18.
[0032] Specifically: the detector 14 monitors the paper position in real time. Once a deviation is detected, it transmits a signal to the hydraulic rod 11. The hydraulic rod 11 pushes the moving block 19, which drives the slider 20 to slide on the sliding column 21. This drives the rotating shaft 18 and the connecting column 17 to rotate the correction roller 26 to correct the deviation. After rewinding, the cylinder 22 works, and the rotating column 12 drives the connecting plate 25 to make the rotating rod 24 rotate around the outside of the outer shell 1, thus making it convenient for the operator to pick up the roll of paper.
[0033] Reference Figure 1 - Figure 5The automatic lifting assembly includes a rotating rod 24, the inner wall of which is rotatably connected to the outer wall of the housing 1. A rotating column 23 is fixedly connected to the outer wall of the rotating rod 24. A cylinder 22 is fixedly connected to the outer wall of the housing 1. A rotating column 12 is fixedly connected to the output end of the cylinder 22. A connecting plate 25 is fixedly connected to the outer wall of the rotating column 12. The conveying and collecting assembly includes a placement roller 13, which places the paper to be processed and provides initial support for the paper. Both ends of the placement roller 13 are rotatably connected to the inner wall of the support frame 2. A motor 3 is fixedly connected to the upper side of the outer wall of the housing 1. A gear 16 is fixedly connected to the output end of the motor 3, driving the gear 16 to rotate, thereby driving the entire conveying roller 7 to rotate. A rotating shaft 8 is rotatably connected to the inner wall of the housing 1. A gear 15 is fixedly connected to one end of the rotating shaft 8. The tooth end of the gear 15 meshes with the tooth end of the gear 16. A rotating shaft 6 is fixedly connected to the wall. A conveying roller 7 is fixedly connected to one end of the rotating shaft 6. A tension roller 9 is fixedly connected to the other end of the rotating shaft 8. A motor 4 is fixedly connected to the lower side of the outer wall of the outer shell 1. A collecting roller 5 is fixedly connected to the output end of the motor 4. The collected paper roll is collected after winding and rewinding. The outer wall of the collecting roller 5 is rotatably connected to the inner wall of the rotating rod 24. The rotating rod 24 is used to easily pick up the processed paper roll. The outer wall of the conveying roller 7 is set on the inner wall of the outer shell 1. The conveying roller 7 is used to convey paper. The outer wall of the gear 16 is rotatably connected to the inner wall of the outer shell 1. The gear 16 is used to drive the gear 15 to rotate. The outer wall of the connecting column 17 is fixedly connected to one end of the correction roller 26. The connecting column 17 is used to drive the correction roller 26 to rotate. The inner wall of the slider 20 is slidably connected to the outer wall of the sliding column 21. The slider 20 is used to drive the moving block 19 to move.
[0034] Specifically: Cylinder 22 drives rotating rod 24 to rotate, causing collecting roller 5 to disengage from rotating rod 24, thus enabling operators to quickly and easily pick up the roll of paper.
[0035] Working principle: When a high-speed cored roll paper rewinder is needed, the paper placed on the placement roller 13 begins the rewinding process. Motor 1 3 starts, and its output drives gear 2 16 to rotate. When gear 2 16 rotates, it drives gear 1 15 to rotate. Gear 1 15 drives shaft 2 8 to rotate. At the same time, gear 2 16 drives shaft 1 6 to rotate, which in turn drives conveyor roller 7 to rotate. Conveyor roller 7 transports the paper from the placement roller 13 to the subsequent processing position. Motor 2 4 starts, driving collection roller 5 to rotate, winding the processed roll paper onto the collection roller. 5. Tension roller 9 applies tension to the paper. Detector 14 monitors the paper position in real time. When a paper position deviation is detected, a signal is transmitted to hydraulic rod 11. The output end of hydraulic rod 11 pushes moving block 19 to move. Moving block 19 drives slider 20 to slide on sliding column 21, ensuring smooth movement of moving block 19. When moving block 19 moves, it drives rotating shaft 3 18 to rotate. Rotating shaft 3 18 drives connecting column 17 to rotate. Connecting column 17 drives correction roller 26 to rotate repeatedly, thereby correcting the paper's deviation and ensuring the accuracy of paper rewinding.
[0036] In addition, after rewinding is completed, the cylinder 22 works, and the rotating column 12 at its output end drives the connecting plate 25, which in turn drives the rotating rod 24 to rotate around the outside of the outer shell 1. Since the collecting roller 5 rotates inside the rotating rod 24, after the work is completed, the rotating rod 24 is moved, and the rotating rod 24 rotates and disengages from the collecting roller 5, realizing the automatic lifting operation, which makes it convenient for the operator to pick up the processed roll of paper.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
