[0029] Specifically, such as Figure 4 As shown, the extrusion assembly 2 includes a support frame 201, which is fixedly connected to the top of the base 3, and an electric telescopic plate 202 is fixedly connected to the inner wall of the support frame 201.

[0030] Specifically, such as Figure 4 As shown, an adjustment frame 203 is fixedly connected to the bottom of the electric telescopic plate 202, and a pressing rod 204 is rotatably connected to both sides inside the adjustment frame 203.

[0031] Specifically, such as Figure 4 As shown, a collection box 205 is fixedly connected to the bottom of the base 3, a discharge pipe 206 is fixedly connected to the bottom of the collection box 205, and a valve body 207 is fixedly connected to the surface of the discharge pipe 206.

[0032] In this embodiment: the support frame 201 connects to the adjustment frame 203; the electric telescopic plate 202 connects to the adjustment frame 203 for lifting and adjustment; the adjustment frame 203 connects to the extrusion rod 204 for rotation; the extrusion rod 204 extrudes the diaphragm coating; the collection box 205 collects the scraped coating; the discharge pipe 206 discharges the scraped coating; and the valve body 207 controls the opening and closing of the discharge pipe 206.

[0034] Specifically, such as Figure 5 As shown, a slot 6 is provided on the top of the plate 5, and a second scraper 7 is fixedly connected to the bottom inside the slot 6.

[0035] In this embodiment: the clamping plate 4 can connect the plate 5, the plate 5 can support the diaphragm coating, the slot 6 can connect the second scraper 7, and the second scraper 7, in conjunction with the first scraper 103, can scrape off the coating on the diaphragm coating.

[0036] Specifically, such as Figure 5 As shown, a slot 8 is provided on the top of the base 3, and the inner wall of the slot 8 is engaged with the bottom of the card plate 4.

[0039] Working principle: First, the base 3 is fixed between the existing placeer and rewinder for diaphragm coating through the fixing holes 9 and fixing bolts 10. Then, according to the width of the diaphragm coating, a plate 5 of appropriate width is selected, and then the plate 5 is installed and fixed by clamping the clamping plate 4 into the clamping slot 8. Then, the diaphragm coating can be pulled to lay the diaphragm coating flat on the plate 5. Then, the electric telescopic plate 202 can be opened, so that the electric telescopic plate 202 can adjust the height of the adjusting frame 203. In turn, the adjusting frame 203 drives the extrusion rod 204 to adjust, so that the bottom of the extrusion rod 204 contacts the top of the diaphragm coating, thereby coating the diaphragm. During the diaphragm coating process, the extrusion process eliminates air bubbles and streaks on the diaphragm coating. Then, the electric telescopic rod 101 is opened, which adjusts the fixing frame 102. This, in turn, causes the fixing frame 102 to adjust the first scraper 103. During the adjustment process, the data transmitted back by the distance sensor 104 is observed in real time, so that the distance between the first scraper 103 and the second scraper 7 is adapted to the thickness of the diaphragm coating. This allows excess coating material to be scraped off during the diaphragm coating process. Combined with the extrusion of the extrusion rod 204, the scraping process of the diaphragm coating can be effectively completed.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
