Description

Technical Field

[0001] This utility model relates to the field of paper winding technology, and in particular to a constant speed winding device. Background Technology

[0002] After paper is produced or cut, it needs to be rolled up in paper tubes for easy transportation and storage.

[0003] Current winding devices, such as the winding device in a slitting machine as described in application number 2024226272849, generally involve wrapping a roll around an air shaft and then rotating the air shaft and the roll located outside it to perform paper winding. However, this winding method has a drawback: as the winding process proceeds, the number of paper layers wrapped around the roll increases, resulting in a larger diameter of the paper roll. If the rotation speed of the air shaft remains unchanged after the number of paper layers increases, the winding speed will increase significantly, affecting the winding quality. Therefore, improvements are needed. Utility Model Content

[0023] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Reference Figures 1-3According to an embodiment of the constant speed winding device of this utility model, it includes a base frame 11, on which two left and right distributed bearing rollers 12 are rotatably connected via mounting bases 92. It also includes an output box 91 for driving the two bearing rollers 12. The output box 91 is used to drive the bearing rollers 12 to rotate. Specifically, the output box 91 is provided with two drive motors. The first output shaft of the drive motor is connected to the two bearing rollers 12 respectively via a universal coupling 93. Through the universal coupling 93, the output box 91 can reduce the accuracy requirements for the relative position of the bearing rollers 12 and the first output shaft when it is independent of the base frame 11.

[0028] In addition, a vertical plate 13 is provided on the front and rear sides of the bottom frame 11, and a lifting frame 14 is slidably connected between the two vertical plates 13. A pressure roller 15 is rotatably connected to the lower side of the lifting frame 14, and a pressing mechanism for controlling the up and down position of the pressure roller 15 is also included.

[0029] Each of the vertical plates 13 is also connected to a telescopic frame 16 via a lifting mechanism. A sliding sleeve 17 is slidably connected in the telescopic frame 16, and a rotating roller 18 is rotatably connected in the sliding sleeve 17. A hand crank 25 is also installed at the ends of the two rotating rollers 18 that are far apart from each other, and a plug sleeve 35 is installed on the side of the two rotating rollers 18 that are close to each other. The system also includes a locking mechanism for controlling the two plug sleeves 35 to move towards each other.

[0030] To ensure the tension of the paper during winding, a swing plate 31 is rotatably connected to each of the two vertical plates 13, and a tension roller 32 is rotatably connected between the two swing plates 31. A cylinder seat 33 is also hinged to the vertical plate 13, and a third piston cylinder 34 is fixed on the cylinder seat 33. The end of the third piston rod in the third piston cylinder 34 is hinged to the swing plate 31. The third piston cylinder 34 is used to control the angle of the swing plate 31 and the tension roller 32, thereby controlling the tension of the paper during winding.

[0031] When the winding operation is performed, the roll for winding the paper is placed between the two carrying rollers 12, and the paper is wound around the roll after being wound around the tension roller 32. Then, the locking mechanism is used to bring the inserts 35 closer to each other, at which time the inserts 35 are inserted into the roll.

[0032] Then, the pressing mechanism lowers the lifting frame 14 until the pressure roller 15 presses on the paper wrapped around the roll. Then, the drive motor is energized and the carrier roller 12 rotates. At this time, the roll rotates and performs winding. The function of the pressure roller 15 is to increase the friction between the carrier roller 12 and the roll and the paper outside the roll, so as to prevent the carrier roller 12 from spinning idly. The function of the insert 35 is to prevent the paper roll from shifting back and forth during the winding process.

[0033] In existing schemes that directly control the rotation of the roll for winding, the winding speed gradually increases as the number of paper layers on the roll accumulates (assuming the roll speed remains constant). However, in the constant speed winding device described above, the process of driving the roll to rotate through the carrier roller 12 for winding can stabilize the winding speed and ensure stable quality of the wound paper.

[0034] It should also be noted that during the rotation and winding of the carrying roller 12, as the number of paper layers around the paper tube increases, the paper tube will gradually move upward. During this process, the pressing mechanism will cause the pressure roller 15 to gradually move upward to ensure that the force applied by the pressure roller 15 to the paper and the roll remains constant. In addition, the lifting mechanism will control the telescopic frame 16 to gradually move upward to avoid deformation of the paper tube due to force.

[0035] In this embodiment, the pressing mechanism includes racks 19 mounted on the two vertical plates 13 respectively, and a dual-axis motor 20 is installed inside the lifting frame 14. A gear meshing with the racks 19 is mounted on the two second output shafts inside the dual-axis motor 20. When the dual-axis motor 20 is powered on, it drives the second output shafts and the gears to rotate, thereby controlling the lifting frame 14 and the pressure roller 15 to move up and down.

[0036] The lifting mechanism includes a first piston cylinder 21 located in the vertical plate 13. The lower end of the first piston rod in the first piston cylinder 21 is fixed to the telescopic frame 16, and the first piston cylinder 21 is covered by a baffle.

[0037] The locking mechanism includes a second piston cylinder 22 located within the telescopic frame 16. A locking sleeve 23 is installed at the end of the second piston rod within the second piston cylinder 22, and the locking sleeve 23 is fixed to the outside of the sliding sleeve 17, which is located within the same telescopic frame 16 as the second piston cylinder 22. The operator can control the second piston cylinder 22, thereby controlling the front and rear positions of the sliding sleeve 17 and the rotating roller 18.

[0038] To maintain structural stability, two support frames 24 are also included, one at the front and one at the back. Several support rods are installed on the lower side of the support frame 24. The bottom frame 11 and the vertical plate 13 are both fixed to the support frame 24.

[0039] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
