Description

Technical Field

[0001] This application relates to the technical field of foil winding, and in particular to a foil winding apparatus. Background Technology

[0002] Current foil winding systems mostly employ passive damping mechanisms or fully automatic electronic control systems. The former relies on the swing roller to respond to tension changes, which has the drawbacks of large inertial delay and poor suppression of high-frequency micro-amplitude fluctuations. The latter, although highly accurate, is complex, costly, and has a delay in electrical signal response. Neither can achieve high-frequency, fast, and precise tension control while ensuring economic efficiency. Utility Model Content

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] See Figure 1-3A foil winding device includes a workbench 1, with connecting plates 3 fixedly connected to the front and rear sides of the top of the workbench 1, a winding roller 4 rotatably connected to the inner wall of the connecting plates 3, a fixing plate 5 fixedly connected to the top of the connecting plates 3, a first support plate 6 fixedly connected to the front and rear sides of the bottom of the fixing plate 5, a first rotating rod 8 rotatably connected to the inner wall of the first support plate 6, a buffer roller 7 fixedly connected to the surface of the first rotating rod 8, and a matching air box 13 fixedly connected to the top of the workbench 1.

[0021] In this application, the bottom sides of the fixed plate 5 are rotatably connected to the first rotating rod 8 via the first support plate 6. The buffer roller 7 fixedly installed on the rod body constitutes the first-stage tension relief mechanism. The electric motor B12 on the back of the rear connecting plate 3 can drive the first rotating rod 8 to rotate actively, so that the buffer roller 7 can perform preliminary tension adjustment on the foil from the foil discharge device 2. The device is equipped with an oscillation generating mechanism composed of the second rotating rod 11 and the cross sleeve 14. The second rotating rod 11 and the first rotating rod 8 are linked through the synchronous wheel 10 and the synchronous belt 9 at the front end, so that the rotation energy of the buffer roller 7 is synchronously converted into the periodic rotation of the cross sleeve 14. During the rotation, the cross sleeve 14 will continuously push the lightweight plate 15 directly below it. The lightweight plate 15 transmits the mechanical vibration to the U-shaped groove 18 of the matching air box 13 through the piston rod 17 fixed at its bottom. This design converts the linear tension fluctuation of the foil into the rotational mechanical energy of the cross sleeve 14, and then dissipates it through the vibration of the lightweight plate 15, thus realizing the mechanical primary tension relief effect.

[0022] An electric motor A is provided on the back of the connecting plate 3 on the rear side. The electric motor A is fixedly connected to the winding roller 4 through a coupling. A tension detection module is provided on the fixed plate 5. A foil material discharge device 2 is fixedly provided on the right side of the top of the workbench 1. Both the front and rear ends of the first rotating rod 8 pass through the connecting plates 3 on the front and rear sides. An electric motor B12 is fixedly connected to the back of the connecting plate 3 on the rear side. The output end of the electric motor B12 is fixedly connected to the rear end of the first rotating rod 8 through a coupling.

[0023] A sensor is installed on the surface of the buffer roller 7. When the sensor detects that the buffer roller 7 is about to reach the end point, the electric motor B12 reverses and swings in the opposite direction. The swinging of the buffer roller 7 is achieved by the cooperation of the electric motor B12 and the sensor.

[0024] The inner wall of the connecting plate 3 is rotatably connected to a second rotating rod 11. A cross sleeve 14 is fixedly fitted on the surface of the second rotating rod 11. The front ends of the second rotating rod 11 and the first rotating rod 8 are both fixedly connected to a synchronous wheel 10. U-shaped grooves 18 are opened on the front and rear sides of the top of the mating air box 13. The left side of the U-shaped groove 18 is a wide groove, and the right side of the U-shaped groove 18 is a narrow groove. A piston rod 17 is slidably connected to the wall of the wide groove of the U-shaped groove 18, and a push rod 19 is slidably connected to the wall of the narrow groove of the U-shaped groove 18. A mating roller 20 is fixedly connected to the top of the push rod 19. A synchronous belt 9 is fitted on the surface of the synchronous wheel 10. Springs 16 are fixedly connected to the front and rear sides of the top of the mating air box 13. The piston rod 17 is located inside the spring 16. A lightweight plate 15 is fixedly connected to the top of the spring 16. The lightweight plate 15 is located at the bottom of the cross sleeve 14. The top of the piston rod 17 is fixedly connected to the bottom of the lightweight plate 15.

[0025] In this application, the U-shaped groove 18 is divided into a wide groove on the left and a narrow groove on the right. The piston rod 17 sliding in the wide groove and the push rod 19 sliding in the narrow groove form a differential air chamber. When the cross sleeve 14 pushes the lightweight plate 15 down, the lightweight plate 15 compresses the spring 16 and pushes the piston rod 17 into the wide groove, compressing the gas in the air chamber. Due to the smaller cross-sectional area of ​​the narrow groove, the compressed gas generates greater pressure, which quickly pushes the push rod 19 and its top mating roller 20 upward, thereby lifting the foil and instantly relaxing its path and releasing tension. When the protruding part of the cross sleeve 14 turns, the lightweight plate 15 is lifted under the reset action of the spring 16, the piston rod 17 rises, and a negative pressure is formed in the air chamber, attracting the push rod 19 to drive the mating roller 20 down, re-tensioning the foil. This high-frequency, small-amplitude up-and-down reciprocating motion of the mating roller 20 continuously performs a "tension-relaxation" cycle on the foil, effectively dissolving concentrated tension fluctuations into high-frequency micro-amplitude vibrations, thereby achieving tension relief control.

[0026] The above-mentioned tension control is divided into two cases;

[0027] When the electric motor B12 rotates forward, it drives the buffer roller 7 to rotate continuously in one direction, making it work as an active tension roller, applying a stable reverse tension to the foil, thereby directly offsetting and absorbing most of the macroscopic tension fluctuations. At the same time, this rotational motion drives the cross sleeve 14 to rotate at a constant speed through the synchronous belt 9, thereby stimulating the mating roller 20 to perform high-frequency, small-amplitude "tension-relaxation" micro-vibration. In this path, this application achieves tension relief by combining "active tensioning" and "high-frequency micro-vibration".

[0028] When the electric motor B12 reverses (i.e., periodically swings forward and backward), the buffer roller 7 transforms into a swinging buffer arm. Its discontinuous motion directly applies a low-frequency mechanical disturbance to the foil, thereby disrupting and dispersing the original tension fluctuations. At the same time, this swinging motion still drives the cross sleeve 14 to rotate, maintaining the high-frequency micro-vibration function of the mating roller 20. In this path, this application dissipates tension energy through the combined effect of "low-frequency mechanical disturbance" and "high-frequency micro-vibration".

[0029] In this application, the take-up roller 4, the buffer roller 7, and the cooperating roller 20 constitute a dynamic tension relief system. The electric motor A drives the take-up roller 4 to provide the main driving force for winding, while the electric motor B12 drives the buffer roller 7 to not only directly participate in tension adjustment, but also distribute the power to the second rotating rod 11 through the synchronous belt 9, making the cross sleeve 14 a controlled mechanical oscillation source within the system. The wide and narrow groove design of the U-shaped groove 18 makes the displacement response speed of the push rod 19 faster than the reset speed of the piston rod 17, forming an asymmetrical motion cycle. This characteristic makes the upward movement of the cooperating roller 20 rapid and decisive in relieving tension, while the downward movement restores contact smoothly and stably, effectively avoiding excessive instantaneous relaxation of the foil. Throughout the process, the macroscopic tension energy of the foil is converted into the rotational energy of the buffer roller 7, the rotational kinetic energy of the cross sleeve 14, the vibrational energy of the lightweight plate 15, and the internal energy of the gas in the air box 13. Finally, through multi-stage conversion and dissipation, the goal of high-efficiency and high-stability tension relief is achieved, ensuring uniform winding quality.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
