Description

Technical Field

[0001] This utility model relates to the technical field of paper tube alignment and correction equipment for rewinding machines, and in particular to a fully automatic paper tube alignment and correction equipment for rewinding machines. Background Technology

[0002] In the modern papermaking industry and related packaging material production, the rewinding process is a crucial step in processing large paper rolls produced by paper machines into smaller paper rolls that meet the requirements of subsequent printing, packaging, and other uses. As the core carrier for paper winding during the rewinding process, the alignment accuracy of the paper tube plays a decisive role in the rewinding quality. Precisely aligned paper tubes ensure consistent tightness and flat ends of the rewound paper, reducing quality problems such as wrinkles and tears, and improving paper yield and production efficiency.

[0003] In existing technologies, the fixed slot size of some mechanical positioning pins is fixed, making it difficult to adapt to paper tubes of different specifications. Furthermore, during the insertion and removal of the positioning pins, operational errors can easily cause the paper tubes to shift, making it difficult to guarantee alignment accuracy. Some devices use a rigid contact correction method, where the positioning pins directly press against the paper tubes during correction, easily leaving indentations or even causing damage to the paper tube surface, affecting its subsequent use. In addition, their complex structure and high precision requirements for the fit of various components not only increase equipment manufacturing costs but also make subsequent maintenance and repair difficult, failing to meet the demands of efficient and high-quality production. Utility Model Content

[0004] The purpose of this invention is to solve the problems of poor alignment accuracy and complex structure that easily damages paper tubes in the existing technology, and to propose a fully automatic rewinding machine paper tube alignment and correction device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fully automatic rewinding machine paper tube alignment and correction device, comprising a support frame, a first rotating roller rotatably connected to one end of the surface of the support frame, a support base fixedly connected to the surface of the support frame, a top plate provided above the support base, the top plate fixedly connected to the surface of the support frame, a lifting structure provided at the top of the top plate, a mounting frame fixedly connected to the upper surface of the support base, a second rotating roller rotatably connected to the surface of the mounting frame, one end of the second rotating roller fixedly connected to the output end of a third motor, the third motor fixedly mounted on the rear surface of the support frame, the lifting structure comprising a hydraulic cylinder, the hydraulic cylinder fixedly mounted on the upper surface of the top plate, a hydraulic rod fixedly connected to the output end of the hydraulic cylinder, a movable plate fixedly connected to the telescopic end of the hydraulic rod passing through the mounting frame, an alignment device provided inside the movable plate, and a sliding connection between the movable plate and the mounting frame.

[0006] Furthermore, the alignment device includes a groove formed at the bottom of the movable plate, a lead screw is disposed inside the groove, a first motor is fixedly connected to the side of the movable plate, the output end of the first motor is fixedly connected to one end of the lead screw, the other end of the lead screw is rotatably connected to the inner wall of the groove, and an alignment plate is threadedly connected to the outer surface of the lead screw.

[0007] Furthermore, the calibration plate includes a connecting block threaded onto the outer surface of the lead screw, a clamping plate fixedly connected to the surface of the connecting block, a connection port provided at the lower end of the clamping plate, and a buffer component provided on the arc-shaped surface of the connection port.

[0008] Furthermore, the buffer assembly includes a spring fixedly connected to the arc-shaped surface of the connection port, and a buffer plate is fixedly connected to the end of the spring away from the arc-shaped surface of the connection port. The buffer assembly has three sets distributed circumferentially at intervals on the arc-shaped surface of the connection port.

[0009] Furthermore, several calibration plates are threadedly connected to the outer surface of the lead screw, and the calibration plates are distributed in a straight line at intervals on the outer surface of the lead screw.

[0010] Furthermore, both ends of the bottom of the support frame are fixedly connected to fixing plates, and a connecting rod is fixedly connected to the upper surface of the fixing plate, and the connecting rod is fixedly connected to the support frame.

[0011] Furthermore, the first rotating roller includes a connecting plate, the bottom of which is fixedly connected to the upper surface of a fixed plate. A second motor is fixedly connected to the side of the first rotating roller, and a rotating drum is fixedly connected to the output end of the second motor. The end of the rotating drum away from the second motor is rotatably connected to a support frame.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by combining a lifting structure with an alignment device, a hydraulic cylinder drives a hydraulic rod to lift a moving plate, allowing for precise adjustment of the alignment device's position based on the paper tube's height. A first motor drives a lead screw to rotate, causing multiple alignment plates to move synchronously, enabling precise calibration from different positions on the paper tube. Compared to the traditional single-point calibration method, this approach allows for more comprehensive detection and adjustment of paper tube deviations, significantly improving alignment accuracy and ensuring the flatness and quality of the rewound paper. Three sets of circumferentially distributed buffer components at the alignment plate connection points, when in contact with the paper tube for calibration, utilize the elastic deformation of springs in conjunction with the buffer plates to form a flexible contact, effectively mitigating impact forces during calibration and preventing scratches, dents, and other damage to the paper tube surface. Furthermore, the overall structure of the equipment is simple, with modular assembly of components, reducing manufacturing costs and facilitating disassembly and maintenance, extending equipment lifespan, and improving production efficiency.

[0015] Please see Figure 1-5 This utility model provides a technical solution: a fully automatic rewinding machine paper tube alignment and correction device, including a support frame 1, a first rotating roller 2 rotatably connected to one end of the surface of the support frame 1, a support base 3 fixedly connected to the surface of the support frame 1, a top plate 4 provided above the support base 3, the top plate 4 fixedly connected to the surface of the support frame 1, a lifting structure 5 provided on the top of the top plate 4, a mounting frame 6 fixedly connected to the upper surface of the support base 3, a second rotating roller 7 rotatably connected to the surface of the mounting frame 6, one end of the second rotating roller 7 fixedly connected to the output end of a third motor, and the third motor fixedly installed on the rear surface of the support frame 1.

[0016] The following section will explain the specific design and function of its lifting structure 5.

[0017] In this embodiment: the lifting structure 5 includes a hydraulic cylinder 51, which is fixedly installed on the upper surface of the top plate 4. The output end of the hydraulic cylinder 51 is fixedly connected to a hydraulic rod 52. The telescopic end of the hydraulic rod 52 passes through the mounting frame 6 and is fixedly connected to a movable plate 53. An alignment device 54 is provided inside the movable plate 53. The movable plate 53 is slidably connected to the mounting frame 6.

[0018] The effect achieved by the above components is that the extension and retraction of the hydraulic rod 52 can be precisely controlled by the operation of the hydraulic cylinder 51, thereby driving the moving plate 53 to slide up and down along the mounting frame 6, realizing flexible adjustment of the height position of the alignment device 54 to adapt to paper tubes of different height specifications, and improving the versatility and applicability of the equipment.

[0019] Specifically, the alignment device 54 includes a groove 541 formed at the bottom of the movable plate 53, a lead screw 542 is provided inside the groove 541, a first motor 543 is fixedly connected to the side of the movable plate 53, the output end of the first motor 543 is fixedly connected to one end of the lead screw 542, the other end of the lead screw 542 is rotatably connected to the inner wall of the groove 541, and an alignment plate 544 is threadedly connected to the outer surface of the lead screw 542.

[0020] The effect achieved by the above components is as follows: after the first motor 543 starts, it drives the lead screw 542 to rotate in the groove 541. Since the calibration plate 544 is threadedly connected to the lead screw 542, according to the principle of thread transmission, the calibration plate 544 will move along the linear direction on the lead screw 542, thereby realizing the synchronous calibration of multiple positions of the paper tube. Compared with the traditional single-point calibration, the calibration efficiency and accuracy are greatly improved.

[0021] Specifically, the calibration plate 544 includes a connecting block 5441 threaded to the outer surface of the lead screw 542, a clamping plate 5442 fixedly connected to the surface of the connecting block 5441, a connecting port 5443 provided at the lower end of the clamping plate 5442, and a buffer component 5444 provided on the arc-shaped surface of the connecting port 5443.

[0022] The effects achieved by the above components are as follows: the connecting block 5441 is used to securely connect the clamping plate 5442 to the lead screw 542, so that the clamping plate 5442 can move with the rotation of the lead screw 542; the connecting port 5443 at the lower end of the clamping plate 5442 can contact the paper tube to realize the positioning and calibration of the paper tube; the buffer component 5444 can play a buffering protection role when the clamping plate 5442 contacts the paper tube.

[0023] Specifically, the buffer assembly 5444 includes a spring 54441 fixedly connected to the arc-shaped surface of the connection port 5443. A buffer plate 54442 is fixedly connected to one end of the spring 54441 away from the arc-shaped surface of the connection port 5443. The buffer assembly 5444 has three sets of components that are circumferentially spaced on the arc-shaped surface of the connection port 5443.

[0024] The effect achieved by the above components is as follows: when the calibration plate 544 moves and comes into contact with the paper tube, the three sets of circumferentially distributed buffer components 5444 can be evenly subjected to force from different directions. The buffer plate 54442 first comes into contact with the surface of the paper tube and is compressed after being squeezed, compressing the spring 54441. The impact force is absorbed by the elastic deformation of the spring 54441, avoiding rigid collision between the calibration plate 544 and the paper tube, and effectively protecting the surface of the paper tube from scratches or pressure damage.

[0025] Specifically, there are several calibration plates 544 threadedly connected to the outer surface of the lead screw 542, and the calibration plates 544 are distributed in a straight line at intervals on the outer surface of the lead screw 542.

[0026] The effect achieved by the above components is that multiple alignment plates 544, which are distributed in a straight line, can simultaneously calibrate multiple positions of the paper tube, comprehensively detect and adjust deviations of the paper tube in different parts, further improve the accuracy of paper tube alignment, and ensure the stable quality of rewound paper.

[0027] Specifically, both ends of the bottom of the support frame 1 are fixedly connected to the fixing plate 11, and the upper surface of the fixing plate 11 is fixedly connected to the connecting rod 12, which is fixedly connected to the support frame 1.

[0028] The effects achieved by the above components are as follows: the fixing plate 11 increases the contact area between the equipment and the ground, enhancing the stability of the equipment; the connecting rod 12 connects the fixing plate 11 and the support frame 1, further reinforcing the structure of the support frame 1, so that the entire equipment remains stable during operation and reduces calibration errors caused by shaking.

[0029] Specifically, the first rotating roller 2 includes a connecting plate 21, the bottom of which is fixedly connected to the upper surface of the fixed plate 11. A second motor 22 is fixedly connected to the side of the first rotating roller 2. A rotating drum 23 is fixedly connected to the output end of the second motor 22. The end of the rotating drum 23 away from the second motor 22 is rotatably connected to the support frame 1.

[0030] The effect achieved by the above components is as follows: the second motor 22 drives the rotating drum 23 to rotate, which in turn drives the first rotating roller 2 to rotate, thereby conveying the paper tube and enabling the paper tube to smoothly enter the calibration working area. In conjunction with the second rotating roller 7, it realizes the stable transmission and calibration operation of the paper tube on the equipment.

[0031] Working principle: When using the paper tube alignment and correction equipment of this fully automatic rewinding machine, first place the paper tube on the first rotating roller 2 and the second rotating roller 7, start the second motor 22 and the third motor to make the first rotating roller 2 and the second rotating roller 7 rotate, driving the paper tube forward. According to the height of the paper tube, start the hydraulic cylinder 51, adjust the extension length of the hydraulic rod 52, and drive the moving plate 53 and the alignment device 54 to rise and fall to the appropriate position.

[0032] Next, the first motor 543 is started, which drives the lead screw 542 to rotate, causing several alignment plates 544 to move synchronously on the lead screw 542 until the connection port 5443 of the alignment plates 544 contacts the paper tube. At this time, the buffer assembly 5444 comes into play, preventing damage to the paper tube through the cushioning of the spring 54441 and the buffer plate 54442. Multiple alignment plates 544 calibrate from different positions on the paper tube, adjusting the paper tube to a precise alignment state, and then the paper tube continues to be conveyed for subsequent rewinding.
