Description

Technical Field

[0001] The utility model relates to the technical field of film material processing, in particular to a winding device. Background Art

[0002] The slitting process is common in membrane products. Since the early production of membrane products is carried out in the form of whole sheets, but the requirements of end products are different, the membrane needs to be cut according to the requirements, and finally the cut membrane needs to be rewound. That is to say, the slitting process includes unwinding, slitting and rewinding steps; taking the isolation membrane as an example, the isolation membrane is one of the components of the lithium battery, and the slitting process is one of the important links in the production of the isolation membrane.

[0003] When the isolation film is rolled up, the rolling pressure is particularly important. Stable rolling pressure will make the rolled isolation film neat and flat. During the production process, due to factors such as differences in the thickness of the isolation film itself and the coating thickness, the rolling air shaft will jump, which will lead to unstable rolling pressure and then produce the phenomenon of rolling ribs. In the subsequent process, the ribs will wrinkle, making it unusable and increasing costs. Utility Model Content

[0030] To further illustrate, the first drive component 3 and the second drive component 4 can be synchronously arranged on the first fixing member 1 or synchronously arranged on the second fixing member 2. This embodiment is described by taking the first drive component 3 and the second drive component 4 being arranged on the first fixing member 1 as an example.

[0031] The first driving assembly 3 includes a transmission bar 31 and a first driving member 32. The transmission bar 31 is arranged on the side of the first fixing member 1 facing the second fixing member 2. The first driving member 32 is connected to the second driving member 43, and the output end of the first driving member 32 is connected to the first transmission bar 31. Specifically, the transmission bar 31 is a rack structure, and the output end of the first driving member 32 is meshed and connected with the transmission bar 31. In this embodiment, the first driving member 32 is a motor.

[0032] The second driving assembly 4 includes a guide member 41, a bearing member 42 and a second driving member 43. The guide member 41 is arranged on the side of the first fixing member 1 facing the second fixing member 2, the bearing member 42 is slidably arranged on the guide member 41, the second driving member 43 is arranged on the first fixing member 1, and the output end of the second driving member 43 is connected to the bearing member 42, and the first driving member 32 is arranged on the bearing member 42. Specifically, the number of the guide members 41 is two, and the two guide members 41 are arranged at intervals on the first fixing member 1, and the bearing member 42 is slidably connected to the two guide members 41. In this embodiment, the second driving member 43 is a cylinder.

[0033] Furthermore, the second driving component 4 also includes a first support member 44 and a second support member 45. The first support member 44 is arranged on the first fixing member 1, the second support member 45 is arranged on the bearing member 42, the second driving member 43 is arranged on the first support member 44, and the output end of the second driving member 43 is connected to the second support member 45.

[0034] Furthermore, the second drive assembly 4 further includes a pneumatic control system (not shown in the figure), wherein the pneumatic control system is connected to the second drive member 43, and the output pressure of the second drive member 43 is adjusted by the pneumatic control system. Specifically, the pneumatic control system adopts a solution combining an existing PLC system with a proportional valve, and the PLC system controls the pneumatic pressure input to the second drive member 43 through the proportional valve, thereby achieving the regulation of the output pressure of the second drive member 43.

[0035] The winding assembly 5 includes a carrier 51, a transmission shaft 52, a reel 53 and a power member (not shown in the figure), the carrier 51 is arranged on the bearing member 42, the transmission shaft 52 is rotatably arranged on the carrier 51, the reel 53 is arranged on the transmission shaft 52, and in the initial state, the reel 53 is in contact with the pressure roller 6, the power member is arranged on the side of the first fixing member 1 away from the transmission bar 31, and the output end of the power member is connected to the transmission shaft 52; the power member drives the transmission shaft 52 to rotate, and the transmission shaft 52 drives the reel 53 to rotate, and the isolation film is wound during the rotation of the reel 53. In specific applications, the number of reels 53 can be at least two, and at least two reels 53 are distributed on the transmission shaft 52 at intervals.

[0036] In specific applications, in order to avoid abrasion to the isolation membrane, the pressure roller 6 can be made of a soft material, such as a rubber roller.

[0037] When in use, the first driving member 32 works and through cooperation with the transmission bar 31, the first driving member 32 will drive the supporting member 42 and the reel 53 to move in the direction close to the pressure roller member 6. After the reel 53 contacts the pressure roller member 6, the power member and the second driving member 43 start to work. Driven by the power member, the reel 53 starts to rotate and reel the isolation film. In the process of reel 53 reeling, as the reeled isolation film increases, the outer diameter of the isolation film on the reel 53 gradually increases, and a force is generated between the pressure roller member 6 and the outermost layer of the isolation film. This force will overcome the force generated by the operation of the first driving member 32, so that the output shaft of the first driving member 32 is reversed, and then the entire reel 53 is pushed to move in the direction away from the pressure roller member 6. At the same time, the first driving member 32 and the second driving member 43 continue to work, so that the reeling process of the isolation film on the outer layer of the reel 53 maintains sufficient pressure with the pressure roller member 6.

[0038] To sum up, during the winding process of the winding component 5, the first drive component 3 continuously provides the winding component 5 with a positive force for contacting the pressure roller 6, and the second drive component 4 provides the winding component 5 with a compensation force for contacting the pressure roller 6. The compensation force overcomes the vibration generated during the working process of the winding component 5, so that the pressure between the winding component 5 and the pressure roller 6 is more stable, thereby avoiding the phenomenon of ribs and wrinkles, and at the same time it is beneficial to reduce costs.
