Description

Technical Field

[0001] The utility model provides an on-line dry wiping device for a rolling roll, belonging to the technical field of roll pressing of battery electrode sheets. Background Art

[0002] During the roll pressing process of a battery electrode sheet rolling roll, stains will adhere to the roll surface. The current mainstream roll wiping technology is to soak a non-woven fabric and then cooperate with a scraper to scrape off the sewage. When the machine stops, there will be residual water on the roll surface, which will stick to the electrode sheet and cause pollution to the electrode sheet. The existing roll drying technology is a movable roll wiping structure driven by a lead screw. This structure cannot effectively cover the entire roll surface, and when the scraper is damaged and fails, it cannot be detected in time, which will cause large-area pollution to the electrode sheet.

[0020] Next, the present utility model will be further described in conjunction with the drawings.

[0021] An on-line dry wiping device for a roller includes two groups of rotating seats and fixed seats; the rotating seats and the fixed seats are in one-to-one correspondence; the rotating seats are all connected to the bearing seats at both ends of the roller through the corresponding fixed seats;

[0022] Both ends of the supporting plate are fixedly connected to the corresponding two rotating seats; a wiping component is arranged inside the supporting plate, and an air extraction box is arranged outside; a negative pressure cavity is continuously formed by air extraction in the air extraction box, and a humidity sensor is arranged therein, and the humidity sensor is connected to an alarm;

[0028] Next, in conjunction with the attached Figures 1-4 drawings and embodiments, the specific implementation manners of the present invention will be further described in detail.

[0029] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings of the embodiments will be briefly introduced below. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0030] The assembly relationship of this embodiment:

[0031] The backing plate 3 is fixed at the front end of the pallet 1, the pressing plate 2 is fixed at the upper end of the pallet 1, the non-woven fabric 4 is connected to the pressing plate 2 by a wing bolt 9 and overlaps on the backing plate 3, the rotating seat 6 is connected to the pallet 1, one end of the fixed seat 5 is connected to the rotating seat 6, and the other end is fixedly connected to the bearing seat 10. The air extraction box 7 is fixedly connected to the rear end of the pallet 1, and the humidity sensor 8 is connected to the air extraction box 7.

[0032] Working principle:

[0033] Connect the non-woven fabric 4 to the pressing plate 2 with bolts, and then fix it to the pallet 1 through the wing bolt 9.
