[0002] Aluminum-plastic film is widely used in lithium battery packaging, electronic communication products, military and medical fields due to its high barrier properties, electrical properties, electrolyte stability and other advantages. During the production process of aluminum-plastic film, the equipment is running at high speed.

During the material collection process, when the rewinding pressure roller presses the material film onto the material shaft, when the pressure roller contacts the material film, the material film will also be scratched due to the speed difference. In order to improve the production efficiency and production quality of the equipment, preventing the material film from being scratched in the material collection unit has become a technical problem that the coating industry urgently needs to solve.

[0021] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] The present invention is used for the anti-scratch material receiving guide roller driving device of aluminum-plastic film, and its structure is as follows Figure 1-3 As shown, it includes a first drive device and a second drive device fixed on the material shaft rotating frame, the first drive device and the second drive device are connected to the material support guide roller 5 and the pressure roller 5-1 through the first magnetic coupling 4 and the second magnetic coupling 4-1 respectively, and also includes a third drive device fixed on the cutter swing arm 8, the third drive device is connected to the cutter swing arm guide roller 7 through the third magnetic coupling 4-2.

[0024] The present invention aims at the guide rollers that have the problem of scratching the material film. The material support guide roller 5, the pressure roller 5-1 and the cutter swing arm guide roller 7 are connected to the electric drive device through a magnetic coupling, and the material support guide roller 5, the pressure roller 5-1 and the cutter swing arm guide roller 7 are actively controlled. Each roller is connected to the electric drive through a magnetic coupling. Before each roller contacts the material film, it is driven first, so that the surface speed of the roller is synchronized with the speed of the material film at the moment of contacting the material film, thereby avoiding scratching the material film. At the same time, in the actual production process, since the tension state of the material film is constantly fine-tuned, the forward speed of the material film is also constantly changing, which leads to a speed difference between the material film and the roller driven by the electric drive, thereby scratching the material film. The connection between the electric drive and the roller through the magnetic coupling is a flexible connection, which can make the material film provide driving force to drive the guide roller to rotate in the actual production process, get rid of the influence of the electric drive on each roller, thereby eliminating the speed difference between the material film and each roller, and avoiding the occurrence of scratch defects on the material film.

[0025] The specific working principle is:

[0026] Before the surface of the material support guide roller 5 contacts the material film, the material support guide roller 5 is first moved by electrically driving the material support guide roller 5 to have an initial speed, so that the linear speed of the surface of the material support guide roller 5 is the same as the forward speed of the material film, thereby avoiding the occurrence of scratch defects caused by speed difference; in the actual production process, since the tension state of the material film is constantly fine-tuned, the forward speed of the material film is also constantly changing, so the driving source of the material support guide roller 5 needs to be changed from the electric drive device to the material film. At this time, the electric drive device needs to disengage the drive of the material guide roller 5, and the flexible connection of the first magnetic coupling 4 allows a relative movement between the material guide roller 5 and the electric drive device, thereby avoiding scratches on the material film due to the inconsistency between the driving speed of the active drive device and the material film speed.

[0027] Before the surface of the pressure roller 5-1 contacts the material film, the pressure roller 5-1 is first moved by electric drive to give it an initial speed. Then, the pressure roller swing arm 6 where the pressure roller 5-1 is located swings, so that the pressure roller 5-1 presses the material film to complete the material collection action. At this time, the second magnetic coupling 4-1 between the pressure roller 5-4 and the electric drive device is disengaged, so that the driving source of the pressure roller 5-1 is changed from the electric drive device to the pressed material film. At this time, the original active drive is completely changed to a passive roller driven by the material film, so that the rotation speed of the pressure roller 5-1 can always be consistent with the forward speed of the material film during the production process, avoiding the occurrence of scratch defects.

[0028] Before the surface of the cutter swing arm guide roller 7 contacts the material film, during the process of the cutter swing arm 8 swinging from the preparation position to the working position, the cutter swing arm guide roller 7 is rotated by electrically driving the cutter swing arm guide roller 7 to have an initial speed, so that the linear speed of the surface of the cutter swing arm guide roller 7 and the forward speed of the material film are the same before they contact each other, thereby avoiding the occurrence of scratch defects caused by speed difference; in the actual production process, since the tension state of the material film is constantly fine-tuned, the forward speed of the material film is also constantly changing, so the driving source of the cutter swing arm guide roller 7 needs to be changed from the electric drive device to the material film. At this time, the electric drive device needs to be disengaged from the drive of the cutter swing arm guide roller 7, and the flexible connection of the magnetic coupling allows a relative movement between the cutter swing arm guide roller 7 and the electric drive device, thereby avoiding scratches on the material film due to the driving speed of the active drive device being inconsistent with the material film speed.

[0029] Example 2

[0030] The present invention is used for the anti-scratch material receiving guide roller driving device of aluminum-plastic film, and its structure is as follows Figure 1-3 As shown, it includes a first drive device and a second drive device fixed on the material shaft rotating frame, the first drive device and the second drive device are connected to the material support guide roller 5 and the pressure roller 5-1 through the first magnetic coupling 4 and the second magnetic coupling 4-1 respectively, and also includes a third drive device fixed on the cutter swing arm 8, the third drive device is connected to the cutter swing arm guide roller 7 through the third magnetic coupling 4-2.

[0031] The first driving device includes a first motor 1 fixed on the material shaft rotating frame, the output end of the first motor 1 is fixedly connected to the input end of the first reducer, the output end of the first reducer is fixedly connected to the first rotating shaft 3, the other end of the first rotating shaft 3 is fixedly connected to one end of the first magnetic coupling 4, and the other end of the first magnetic coupling 4 is fixedly connected to one end of the supporting material guide roller 5. The first motor 1, the first reducer, the first rotating shaft 3, the first magnetic coupling 4 and the supporting material guide roller 5 are connected together to form a roller driving device on the material shaft rotating frame.

[0032] The working principle of this embodiment is:

[0033] Working principle of the over-roller driving device: before the surface of the support guide roller 5 contacts the material film, the support guide roller 5 is first driven to move by the first motor 1 so that it has an initial speed, so that the linear speed of the surface of the support guide roller 5 is the same as the forward speed of the material film, thereby avoiding the occurrence of scratch defects caused by speed difference; in the actual production process, since the tension state of the material film is constantly fine-tuned, the forward speed of the material film is also constantly changing, so the driving source of the support guide roller 5 needs to be changed from the active drive of the first motor to the passive drive of the material film. At this time, the drive of the first motor 1 to the support guide roller 5 needs to be disengaged, and the flexible connection of the first magnetic coupling 4 allows a relative movement between the support guide roller 5 and the output end of the motor 1, thereby avoiding scratches on the material film due to the inconsistency between the driving speed of the active drive device and the material film speed.

[0034] Before the surface of the pressure roller 5-1 contacts the material film, the pressure roller 5-1 is first moved by electric drive to give it an initial speed. Then, the pressure roller swing arm 6 where the pressure roller 5-1 is located swings, so that the pressure roller 5-1 presses the material film to complete the material collection action. At this time, the second magnetic coupling 4-1 between the pressure roller 5-4 and the electric drive device is disengaged, so that the driving source of the pressure roller 5-1 is changed from the electric drive device to the pressed material film. At this time, the original active drive is completely changed to a passive roller driven by the material film, so that the rotation speed of the pressure roller 5-1 can always be consistent with the forward speed of the material film during the production process, avoiding the occurrence of scratch defects.

[0035] Before the surface of the cutter swing arm guide roller 7 contacts the material film, during the process of the cutter swing arm 8 swinging from the preparation position to the working position, the cutter swing arm guide roller 7 is rotated by electrically driving the cutter swing arm guide roller 7 to have an initial speed, so that the linear speed of the surface of the cutter swing arm guide roller 7 and the forward speed of the material film are the same before they contact each other, thereby avoiding the occurrence of scratch defects caused by speed difference; in the actual production process, since the tension state of the material film is constantly fine-tuned, the forward speed of the material film is also constantly changing, so the driving source of the cutter swing arm guide roller 7 needs to be changed from the electric drive device to the material film. At this time, the electric drive device needs to be disengaged from the drive of the cutter swing arm guide roller 7, and the flexible connection of the magnetic coupling allows a relative movement between the cutter swing arm guide roller 7 and the electric drive device, thereby avoiding scratches on the material film due to the driving speed of the active drive device being inconsistent with the material film speed.

[0045] The working principle of this embodiment is:

[0046] Working principle of the roller drive device:

[0047] Before the surface of the support guide roller 5 contacts the material film, the support guide roller 5 is first driven to move by the first motor 1 so that it has an initial speed, so that the linear speed of the surface of the support guide roller 5 is the same as the forward speed of the material film, thereby avoiding the occurrence of scratch defects caused by speed difference; in the actual production process, since the tension state of the material film is constantly fine-tuned, the forward speed of the material film is also constantly changing, so the driving source of the support guide roller 5 needs to be changed from the active drive of the first motor to the passive drive of the material film.

[0065] The working principle of this embodiment is:

[0066] Working principle of the roller drive device:

[0067] Before the surface of the support guide roller 5 contacts the material film, the support guide roller 5 is first driven to move by the first motor 1 so that it has an initial speed, so that the linear speed of the surface of the support guide roller 5 is the same as the forward speed of the material film, thereby avoiding the occurrence of scratch defects caused by speed difference; in the actual production process, since the tension state of the material film is constantly fine-tuned, the forward speed of the material film is also constantly changing, so the driving source of the support guide roller 5 needs to be changed from the active drive of the first motor to the passive drive of the material film.

[0068] Working principle of winding roller drive device:

At this time, the original active drive is completely transformed into a passive roller driven by the material film, so that the rotation speed of the pressure roller 5-1 can always be consistent with the forward speed of the material film during the production process, avoiding the occurrence of scratch defects.

[0070] The working principle of the upper roller drive device of the cutter swing arm is:

[0071] Before the surface of the cutter swing arm guide roller 7 contacts the material film, during the process of the cutter swing arm 8 swinging from the preparation position to the working position, the third motor 1-2 is driven to drive the driven pulley 3-3, thereby driving the cutter swing arm guide roller 7 to rotate, so that it has an initial speed, so that the linear speed of the surface of the cutter swing arm guide roller 7 and the forward speed of the material film are the same before they contact each other, thereby avoiding the occurrence of scratch defects caused by speed difference; in the actual production process, since the tension state of the material film is constantly fine-tuned, the forward speed of the material film is also constantly changing, so the driving source of the cutter swing arm guide roller 7 needs to be changed from the electric drive device to the material film. At this time, the electric drive device needs to be disengaged from the drive of the cutter swing arm guide roller 7, and the flexible connection of the magnetic coupling allows a relative movement between the cutter swing arm guide roller 7 and the electric drive device, thereby avoiding the driving speed of the active drive device being inconsistent with the material film speed and scratching the material film.

[0072] The present invention is different from the traditional guide roller design. The traditional structural design adopts a passive design. During the working actions of the disc rotating, the built-in pressure roller pressing down, and the cutter arm lifting in the winding process, the passive guide roller will change from a state of zero speed to a state of working speed, and the high-speed moving material film provides power for the passive guide roller. The present invention adopts the structural design of an active roller, and drives each guide roller through a motor so that the guide roller has a certain initial velocity before contacting the material film. Secondly, a magnetic coupling is used to achieve a flexible driving connection between the guide roller and the motor. When the guide roller with a certain initial velocity contacts the material film, the motor drive disengages from the guide roller. At this time, the guide roller will only be driven by the material film, so that there is a relative movement between the guide roller and the motor shaft, and the surface speed of the guide roller is synchronized with the material film to avoid the risk of scratches.
