[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] The utility program mainly improves the Japanese Toshiba wet lithium battery diaphragm equipment. At present, the extraction tank in the Japanese Toshiba wet lithium battery diaphragm equipment is relatively simple in design, and the production line speed is not considered during design, so that after the production line speed is increased, the production line parts are damaged seriously, the drying box structure is short and the drying capacity is weak, and it is difficult to dry. The present scheme mainly replaces the parts in the extraction tank of the wet lithium battery diaphragm equipment to speed up the equipment and achieve better service life. The scraping liquid roller 4 device in the extraction tank is mainly replaced to achieve good liquid scraping effect. At the same time, the limited space of the original Japanese Toshiba equipment design is transformed, the scraping liquid device and the drying box are combined, and better drying effect is achieved.

[0023] Embodiment one:

[0024] Based on the technical defects of uneven scraping of the prior art, please refer to Figures 1-4 The scraping liquid roller structure for lithium battery diaphragm equipment provided by the utility model can improve the scraping effect, reduce the liquid amount of the film in production, make the film surface effect better, and includes two left and right symmetrical extraction tank side plates 1, welding plates 2 are installed on the side walls of the two extraction tank side plates 1, sealing plates 201 are arranged between the welding plates 2 and the extraction tank side plates 1, two groups of upper and lower symmetrical support mechanisms 3 are installed on the side wall of the welding plate 2, and the scraping liquid roller 4 and the straight roller 5 are rotatably connected between the two groups of horizontally arranged support mechanisms 3. When assembling, the welding plate 2 and the bearing seat 301 are firmly installed, then the ball bearing 302 is sleeved on the two ends of the scraping liquid roller 4 and the straight roller 5, and the outer end cover 303 and the inner end cover 307 are used to fix them.

[0025] The support structure at both ends of the existing scraping liquid roller 4 is prone to wear during high-speed operation, so that the scraping liquid roller 4 runs unstably, and the scraping effect on the die surface is poor. To solve this problem, please refer to Figure 2The support mechanism 3 comprises a bearing seat 301 mounted on the side wall of the welding plate 2, a ball bearing 302 sleeved in the bearing seat 301, the ball bearing 302 being sleeved at one end of the liquid scraping roller 4, one side of the ball bearing 302 being provided with an outer end cover 303 mounted on the side wall of the bearing seat 301, the other side of the ball bearing 302 being provided with an inner end cover 307 mounted on the side wall of the extraction tank side plate 1, the inner end cover 307 being sleeved with a gasket 308, the inner end cover 307 being sleeved on the outer wall of one end of the liquid scraping roller 4, and the welding plate 2 and the bearing seat 301 being further connected with an adjusting assembly 306; after the bearing seat 301 is mounted on the welding plate 2, the ball bearing 302 is then sleeved at one end of the liquid scraping roller 4 and fixed by using the outer end cover 303 and the inner end cover 307, and the ball bearing 302 is assembled at both ends thereof, so that the wear of the liquid scraping roller 4 at both ends is reduced after the production line is speeded up, and the liquid scraping roller 4 can also maintain a stable state during high-speed operation, thereby improving the liquid scraping effect, reducing the liquid amount of the film during production, and making the film surface effect better.

[0026] During actual assembly, due to certain assembly errors, the two horizontally arranged support mechanisms 3 are not on the same horizontal axis, thereby causing the problem that the liquid scraping roller 4 cannot be installed well during subsequent installation. Figure 2 The adjusting assembly 306 comprises a fixing seat 3061 fixedly connected to the welding plate 2, and an adjusting screw 3062 rotatably connected to the fixing seat 3061, one end of the adjusting screw 3062 being threadedly connected to a threaded seat 3063 fixedly connected to the bearing seat 301; by rotating the adjusting screw 3062 and moving the threaded seat 3063, the bearing seat 301 is moved forward and backward as a whole, and the forward and backward positions of the bearing seat 301 can be adjusted according to the assembly error, so as to ensure that the two support mechanisms 3 are on the same axis, thereby facilitating the subsequent installation of the liquid scraping roller 4 and the straight roller 5, and having a certain error compensation effect.

[0027] Since the ball bearing 302 is used as the support, the liquid in the extraction tank is prone to leak from the position of the ball bearing 302, and in order to avoid the leakage problem, a skeleton oil seal 304 is fixedly arranged on the inner side of the outer end cover 303; the skeleton oil seal 304 is a sealing element used in mechanical equipment, mainly used for preventing oil, lubricating grease or other fluids from leaking. It is composed of elastic material and metal skeleton, and can withstand certain pressure and temperature while maintaining good sealing effect.

[0028] In order to ensure that the outer end cover 303 and the skeleton oil seal 304 are installed in place during assembly, a limiting ring 305 is fixedly arranged on the outer wall of one end of the liquid scraping roller 4 and the straight roller 5 close to the skeleton oil seal 304; the limiting ring 305 is located on one side of the skeleton oil seal 304, and has a limiting effect on the outer end cover 303 and the skeleton oil seal 304.

[0029] Since the bolt connection is adopted between the extraction tank side plate 1 and the welding plate 2, there is also a gap between the two, so liquid leakage is easy to occur in actual use, in order to avoid this problem, the sealing plate 201 is arranged between the welding plate 2 and the extraction tank side plate 1; by the sealing plate 201 adhering between the two, the function of the sealing ring is equivalent, the sealing effect can be provided, so as to achieve the purpose of reducing leakage.

[0030] The liquid scraping roller 4 needs appropriate rotating speed in the coating process to ensure uniform liquid coating, and too high rotating speed can cause liquid splashing or uneven coating, therefore the outer wall of one end of the liquid scraping roller 4 is sleeved with the shaft sleeve 6, and the speed reducer 7 is installed on the shaft sleeve 6; the speed reducer 7 can provide more accurate rotating control, ensure the coordination of the rotating of the liquid scraping roller 4 and the coating speed, and maintain the uniformity and quality stability of the film coating.

[0031] It should be noted that the terms "comprising", "containing" or any other variant thereof are intended to cover non-exclusive inclusions, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or includes elements inherent to such process, method, article or equipment.

[0032] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
