Description

Technical Field

[0001] The present application relates to the field of diaphragm slitting equipment, and in particular to a magnetic roller that is easy to clean. Background Art

[0002] With the continuous development of science and technology, human beings have a higher demand for energy. As a highly efficient energy storage device that can be repeatedly charged and discharged, lithium batteries have been widely used in new energy vehicles, 3C products, Bluetooth headsets and other fields.

[0003] As an important component of the battery, the diaphragm plays the role of electrolyte isolation and battery protection. At the same time, the quality of the diaphragm has a crucial impact on the processing and performance of lithium batteries. Once the diaphragm has problems such as poor appearance, it will affect the processing accuracy and battery performance of the battery.

[0004] Usually, the production scale of base membrane is very large, and it is difficult to ensure that the membrane surface is free of deformation, edge collapse, etc. Therefore, coating one or more layers of micron-thick powder on the outer layer of the base membrane can not only effectively cover the original base membrane edge collapse and deformation problems; but also improve the diaphragm's liquid retention, thermal stability, and puncture performance, and ultimately reduce battery short circuits, enhance battery cycle life, and prevent battery swelling.

[0005] As lithium battery / diaphragm production equipment, strict attention should be paid to the control of metal particles. Metal particles may pierce the diaphragm and pole piece, thus causing battery fire and explosion. Therefore, most diaphragm production equipment is equipped with magnetic bars to attract metal foreign matter, and the magnetic bars are cleaned after shutdown. However, due to the rapid accumulation of metal particles, frequent shutdowns are required for cleaning, which has a great impact on production efficiency. In addition, some magnetic bars are not easy to clean, which further affects the cleaning efficiency and cleaning effect. In other words, the current magnetic roller has the defect of being inconvenient to clean. Utility Model Content

DETAILED DESCRIPTION

[0046] The following is combined with Figure 1-2 , further details of this application are given.

[0047] The present application embodiment discloses a magnetic roller that is easy to clean. Figure 1 and Figure 2 , a magnetic roller that is easy to clean, includes a body, a magnetic roller 2, a sleeve 3 and a cleaning component 4.

The sleeve 3 is provided with a plurality of through holes 32, and the plurality of through holes 32 are arranged in an array along the circumference of the sleeve 3. Two groups of cleaning windows 31 are also provided on the sleeve 3, and the two groups of cleaning windows 31 are symmetrically arranged at the two ends of the axial direction of the sleeve 3, and one group of cleaning windows 31 includes two cleaning windows 31 symmetrically arranged about the axis of the sleeve 3. The cleaning component 4 is installed on the magnetic roller 2, and the cleaning component 4 is used to clean the metal particles attached to the magnetic roller 2.

[0048] Under the attraction of the magnetic roller 2, the metal particles can enter the sleeve 3 through the through hole 32 and adhere to the magnetic roller 2. The metal particles can gather in the sleeve 3. The metal particles attached to the magnetic roller 2 are cleaned by the cleaning component 4 and removed from the sleeve 3 through the cleaning window, thereby completing the cleaning of the magnetic roller 2.

[0049] During the cleaning process of the cleaning component 4, the main body, i.e., the diaphragm production equipment, can be used normally without stopping, and the normal working efficiency of the diaphragm production equipment can be maintained. In addition, the cleaning component 4 can accurately clean the adhesion on the magnetic roller 2, i.e., the magnetic roller 2 has excellent cleaning effect and cleaning efficiency.

[0050] Reference Figure 1 and Figure 2 Each cleaning window extends along the circumference of the sleeve 3, and the length of the cleaning window in the circumference of the sleeve 3 is less than 1 / 2 of the circumference of the sleeve 3. That is, the cleaning windows in a group will not penetrate the sleeve 3, so that the sleeve 3 can be stably connected to the magnetic roller 2. The size of the through hole 32 located on the sleeve 3 is 2-5mm, that is, the diameter of the through hole 32 can be 2mm, 3mm, or 5mm, which can be selected according to actual needs. The through hole 32 with a suitable aperture can allow metal particles to pass through the sleeve 3 smoothly and be attracted by the magnetic roller 2.

[0051] Reference Figure 1 and Figure 2The magnetic roller 2 includes a magnetic section 21 and two non-magnetic bearing sections 22. Specifically, the magnetic section 21 is a magnetic rod, and the length of the magnetic rod is less than the length of the sleeve 3. Further, the length of the magnetic rod is less than the distance between two adjacent cleaning windows in the axial direction of the sleeve 3, that is, the cleaning window can expose the non-magnetic bearing section 22. Each non-magnetic bearing section 22 includes a connecting portion 221 and a sealing portion 222. Specifically, the connecting portion 221 is a connecting rod, one end of the connecting portion 221 is fixedly connected to the magnetic section 21, and the other end of the connecting portion 221 is connected to the body. The sealing portion 222 is a baffle, and the sealing portion 222 can close the open end of the sleeve 3, and the sealing portion 222 is tightly against the inner wall of the sleeve 3.

[0052] Reference Figure 1 and Figure 2 The cleaning assembly 4 includes a cleaning plate 41 and a driving member. The number of the cleaning plate 41 and the driving member are both two. The cleaning plate 41 is sleeved outside the magnetic section 21. The cleaning plate 41 can slide axially along the sleeve 3. The cleaning plate 41 is formed into a circular ring structure. There is a gap between the cleaning plate 41 and the inner wall of the sleeve 3. Each driving member includes two pull rods 42. The two pull rods 42 are symmetrically arranged on both sides of the magnetic section 21. One end of each pull rod 42 is connected to one end of the cleaning plate 41 close to the sealing portion 222, and the other end of each pull rod 42 extends to the outside of the sleeve 3 through the sealing portion 222. The cleaning plate 41 is driven to move along the magnetic section 21 by the pull rod 42, and the metal particles attached to the magnetic section 21 are driven to move synchronously until the metal particles move to the non-magnetic bearing section 22 and move out of the cleaning window 31. The provision of two cleaning plates 41 can shorten the time for cleaning the magnetic roller 2 and improve the cleaning efficiency.

[0053] The implementation principle of the easy-to-clean magnetic roller of the embodiment of the present application is as follows: when the metal particles need to be cleaned, the pull rod 42 is pulled to drive the corresponding cleaning plate 41 to move away from the center of the magnetic roller 2, thereby driving the metal particles attached to the magnetic roller 2 to move until they move to the cleaning window, completing one cleaning of the magnetic roller 2, and then pushing the pull rod 42 toward the center of the magnetic roller 2 to push the cleaning plate 41 to the center of the magnetic roller 2 again, so as to facilitate the next cleaning of the magnetic roller 2. During the cleaning process, the production device does not need to be shut down, and the production efficiency is maintained, and the cleaning operation is simple and the effect is excellent.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
