Description

Technical Field

[0001] This utility model relates to the field of paper production and processing technology, and in particular to a paper winding device that prevents breakage. Background Technology

[0002] In the field of paper winding technology, traditional winding devices typically consist of a paper roll, a drive motor, and a tension control system. The motor drives the roll to rotate, completing the paper winding operation. Existing technologies generally use pneumatic or mechanical clutches to adjust the winding tension, and some systems introduce PID control algorithms to achieve dynamic tension balance, preventing the paper from being too tight or too loose.

[0003] A search revealed that patent CN209367487U discloses a paper winding device that prevents breakage. It uses a pull rod to adjust the clamping device for easy fixing of the central shaft, and uses an air expansion shaft for installing the winding roll, making disassembly and fixing convenient. Furthermore, it employs a tensioning device in conjunction with a linear displacement sensor, and uses a microcontroller to control the drive motor to adjust the unloading tension with high precision, effectively ensuring the stability of paper winding and enabling better paper winding.

[0004] However, the above-mentioned device still has the following drawbacks: It relies on a linear displacement sensor to detect the position of the moving support frame and adjusts the drive motor frequency via a microcontroller, which is a single feedback control. It does not consider factors such as dynamic changes in paper tension, inertia, and motor response delay, easily leading to control lag or oscillation. Furthermore, it cannot achieve active tension adjustment. Secondly, if paper breaks during the winding process, the system will continue to operate, potentially causing the paper on the roll surface to become loose.

[0005] Therefore, this utility model proposes a paper winding device that prevents paper breakage in order to address the above-mentioned shortcomings. Utility Model Content

[0026] 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.

[0027] Reference Figures 1-3 An embodiment of this utility model provides a paper winding device to prevent breakage, comprising a base 1, a vertical plate 2 fixed to the side of the upper surface of the base 1, a winding motor 3 fixed to the top surface of the vertical plate 2, a drive shaft 4 fixed to the output end of the winding motor 3, an air shaft 5 fixed to the other end of the drive shaft 4, and a winding drum 6 sleeved on the surface of the air shaft 5, a support component 7 provided on the side of the upper surface of the base 1 facing the winding motor 3, a tension adjustment component 8 provided in the middle of the surface of the vertical plate 2, a paper clamping component 9 installed on the top of the other side of the surface of the vertical plate 2, and a controller 10 installed on the surface of the vertical plate 2.

[0028] In this embodiment, the controller 10 can be a PLC controller, specifically the S7-1200 series CPU 1214C (6ES7 214-1BG40-0XB0).

[0029] The support assembly 7 includes an electric telescopic rod 71 fixed to the upper surface of the base 1. A tray 72 is installed at the top telescopic end of the electric telescopic rod 71. The end of the air shaft 5 away from the winding motor 3 is located on the surface of the tray 72. The electric telescopic rod 71 is electrically connected to the controller 10.

[0030] The electric telescopic rod 71 can be extended or shortened by the controller 10. When the electric telescopic rod 71 is extended, the pallet 72 supports the air shaft 5, and the air shaft 5 drives the roll 6 to rotate, making the paper winding more stable. When it is necessary to replace the roll 6, the electric telescopic rod 71 can be started first to drive the pallet 72 to descend. At this time, the roll 6 can be removed from the support assembly 7.

[0031] The tension adjustment assembly 8 includes a linear motor 81 fixed to the surface of the vertical plate 2, and a square tube 82 is fixed to the moving end surface of the linear motor 81, with the opening of the square tube 82 facing downward. A square rod 83 is slidably connected inside the square tube 82. A pressure sensor 84 is fixed to the inner top wall of the square tube 82. A spring 85 is provided between the pressure measuring end of the pressure sensor 84 and the top end of the square rod 83. An adjustment shaft 86 is rotatably connected to the bottom of the square rod 83 through a bearing.

[0032] Both the pressure sensor 84 and the linear motor 81 are electrically connected to the controller 10.

[0033] In this embodiment, the pressure sensor 84 is model JC410.

[0034] When the paper passes over the bottom of the adjusting rod 86, the paper exerts an upward pushing force on the adjusting rod 86, causing the square rod 83 to move upward along the square tube 82. The spring 85 is compressed, and the other end of the spring 85 compresses the pressure sensor 84. The pressure sensor 84 monitors the tension of the paper in real time during its movement. This tension value is fed back to the controller 10, which then drives the linear motor 81 to move the entire structure on its surface upward or downward, thereby changing the height of the adjusting rod 86. This achieves active tension adjustment. When the tension on the paper increases, the linear motor 81 drives the adjusting rod 86 upward; when the tension on the paper decreases, the linear motor 81 drives the adjusting rod 86 downward. This ensures that the surface tension of the paper remains constant within a certain range, preventing the paper from breaking.

[0035] The square tube 82 has a strip-shaped opening 87 on its side wall, and a slider 88 is fixed on the surface of the square rod 83. The slider 88 is slidably connected to the strip-shaped opening 87.

[0036] By setting the slider 88 to move within the slot 87, the square rod 83 can be prevented from detaching from the bottom of the square tube 82.

[0037] The paper clamping assembly 9 includes an electromagnetic telescopic rod 92 and a fixed rod 91 fixed to the surface of the vertical plate 2. A pressure rod 93 is fixedly connected to the telescopic end of the bottom of the electromagnetic telescopic rod 92. The pressure rod 93 is located directly above the fixed rod 91. The electromagnetic telescopic rod 92 and the winding motor 3 are both electrically connected to the controller 10.

[0038] When the paper breaks, the pressure sensor 84 instantly loses its squeezing force. After the signal is fed back to the controller 10, the controller 10 controls the winding motor 3 to stop rotating and controls the electromagnetic telescopic rod 92 to extend, thereby driving the pressure rod 93 to descend. The pressure rod 93 and the fixing rod 91 are used to clamp the paper to prevent the paper on the surface of the roll 6 from becoming loose.

[0039] Working principle: After passing between the fixed rod 91 and the pressure rod 93, the paper passes under the adjusting rod 86 and then winds onto the surface of the roll 6. The paper passes under the adjusting shaft 86 of the tension adjusting assembly 8, and the paper tension generates an upward thrust on the square rod 83, causing it to slide within the square tube 82 and compress the spring 85. The other end of the spring 85 presses against the pressure sensor 84, which transmits the real-time detected tension signal to the controller 10. The controller 10 compares and calculates based on the set value and outputs a control signal to drive the linear motor 81 to move the square tube 82, square rod 83, and adjusting shaft 86 upwards or downwards as a whole, thereby dynamically adjusting the paper tension: when the tension increases, the linear motor 81 drives the adjusting shaft 86 upwards; when the tension decreases, it moves downwards to maintain constant tension and prevent breakage. During winding, the winding motor 3 drives the air shaft 5 and the winding roll 6 to rotate via the drive shaft 4 for winding. The electric telescopic rod 71 of the support assembly 7 can control the lifting and lowering of the support plate 72 to assist in supporting the air shaft 5 or facilitate the disassembly of the winding roll 6. If a paper break occurs, the signal of the pressure sensor 84 changes abruptly, and the controller 10 immediately stops the winding motor 3 and starts the electromagnetic telescopic rod 92 of the paper clamping assembly 9 to push the pressure rod 93 down, which together with the fixing rod 91 clamps the paper to prevent the roll from loosening.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
