Description

Technical Field

[0001] The present application relates to the field of edge material winding, and in particular to an edge material outer protection mechanism for a rubber roller. Background Art

[0002] 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.

[0003] As one of the most common equipment in the diaphragm industry, the independent arm slitting machine has a unique winding structure that ensures that each workstation will not affect each other, reducing the occurrence of problems such as warping and jagged edges. The pressure roller at the winding position plays a vital role. The pressure roller is divided into various materials such as steel rollers and rubber rollers. The steel roller has low roughness and high hardness. It can achieve a good winding effect under the action of tension. However, the high hardness causes the winding core to continuously hit the steel roller, causing the diaphragm to stretch and produce ribs. In order to improve the disadvantages of steel rollers, the most widely used winding pressure roller in the industry is now a rubber roller. However, when the independent arm slitting machine is winding, the width of the edge material is usually much narrower than the normal winding width. Under the same slitting parameters, the actual winding tension and pressure of the edge material are relatively large, which will cause irreversible indentations and deformation on the surface of the rubber roller.

[0004] In the related art, a gasket is sleeved on the outer circumference of the rubber roller, and the rubber roller is separated from the edge material by the gasket, so as to prevent the edge material from directly contacting the surface of the rubber roller when the edge material is rolled up, thereby reducing the possibility of indentation and deformation of the pressure roller. In view of the above technical solution, the inventor believes that when the axial position of the edge material rolling changes, the axial position of the gasket on the rubber roller needs to be adjusted synchronously. However, the friction between the inner side of the gasket and the surface of the rubber roller is large, and it is difficult to slide on the surface of the rubber roller, and it is not easy to adjust the axial position of the gasket on the rubber roller. Utility Model Content

[0005] In order to facilitate the adjustment of the axial position of the gasket on the rubber roller, the present application provides an edge material outer protection mechanism for the rubber roller.

[0006] The present application provides a rubber roller edge material outer protection mechanism, which adopts the following technical solution:

[0008] By adopting the above technical solution, when the axial position of the edge material winding changes, the gasket body can be removed from the rubber roller by splitting the gasket body into a male half ring and a female half ring, so as to facilitate the adjustment of the installation position of the gasket body. After the installation position is determined, the male half ring and the female half ring are assembled and fixed to form a complete gasket body. The present application provides a detachable gasket body, which protects the rubber roller and facilitates the adjustment of its own installation position on the rubber roller.

[0016] By adopting the above technical solution, the gasket body is guaranteed to have a better service life. In addition, stainless steel has good rigidity and relies on its own rigid structure to prevent the edge material from squeezing the rubber roller when the edge material is rolled up, thereby preventing the rubber roller from being irreversibly damaged.

When installing, just plug the plug connector and the plug slot into place to assemble the gasket body, which is convenient and quick.

[0019] Optionally, a guide slope is provided on one side of the clamping block close to the opening of the plug-in slot, and when the elastic member is at the compression limit, the guide slope is entirely located in the mounting slot; when the elastic member is in a natural state, one end of the guide slope extends out of the mounting slot, and the other end is located in the mounting slot.

[0020] By adopting the above technical solution, when the plug connector is inserted into the plug slot, the plug connector can be squeezed into the guide slope to compress the clamping block into the installation slot, and the elastic member is compressed to accumulate force. The plug connector is continued to be inserted until the position of the clamping slot is relative to the installation slot, and the elastic member is reset to bounce the clamping block into the clamping slot, thereby realizing the splicing and fixation of the male half ring member and the female half ring member.

When the elastic member 411 is at the compression limit, the guide slope 421 is completely located in the installation slot 41. When the elastic member 411 is in the natural state, one end of the guide slope 421 extends out of the installation slot 41, and the other end is located in the installation slot 41. When the plug connector 3 is inserted into the plug slot 4, the clamping block 42 can be compressed into the installation slot 41 by squeezing the guide slope 421 by the plug connector 3. The elastic member 411 is compressed and stored. When the plug connector 3 is inserted further until the positions of the clamping slot 31 and the installation slot 41 are opposite, the elastic member 411 is reset, and the clamping block 42 is ejected into the clamping slot 31, so as to realize the splicing and fixation of the male half ring member 21 and the female half ring member 22.
