Description

Technical Field

[0001] The invention relates to the technical field of roller press processing, and in particular to a roller press with an automatic spraying and wiping roller structure and a working method thereof. Background Art

[0002] The rolling of battery pole pieces refers to the process in which the friction between the rollers and the battery pole pieces in the roller press pulls the battery pole pieces between the rotating upper and lower roller systems, and the battery pole pieces are compressed and deformed. The rolling of battery pole pieces is a process of combining and compacting the battery materials and substrates on the positive and negative plates. Its purpose is to increase the compaction density of the positive or negative electrode materials. The bonding strength between the battery materials and the substrate directly determines the cycle life of the battery. However, since the battery materials and the substrate are not made of the same material, they are easy to separate and it is not easy to ensure the compaction density.

[0003] The rollers of a roller press are prone to uneven loads during long-term use, which can cause the rollers to bend and deform, affecting the flatness of the processed battery electrodes. At the same time, the roller spacing adjustment steps of the roller press are cumbersome, which can lead to uneven product thickness, reduced surface quality and reduced production efficiency during the processing. After the processing is completed, coarse particles and dust particles will be attached to the roller surface. A single scraper structure can only remove the coarse particles on the roller surface, and the scraper mechanism cannot remove the cleaning liquid attached to the roller surface. Directly spraying the rollers through a spray mechanism will cause the cleaning liquid to splash, and the splashed cleaning liquid carries dust particles that pollute the equipment as a whole. Summary of the invention

[0004] The problem solved by the present invention is to provide a roller press with an automatic spraying and wiping roller structure and a working method thereof, which solves the problem that the rollers of the roller press are easily subjected to uneven loads during long-term use, which leads to bending and deformation of the rollers, affecting the flatness of the processed battery pole pieces. At the same time, the roller spacing adjustment steps of the roller press are cumbersome, which leads to uneven thickness of the product, reduced surface quality and reduced production efficiency during the processing. After the processing is completed, coarse particles and dust particles will be attached to the roller surface. Only the coarse particles on the roller surface can be removed by a single scraper structure, and tiny particles such as dust cannot be removed, thereby affecting the product quality and equipment.

[0015] The beneficial effects of the present invention are as follows: the gap adjustment mechanism is used to adjust the gap between the upper roller and the lower roller, and the gap adjustment mechanism includes two modes: coarse adjustment and fine adjustment, thereby accurately controlling the thickness of the negative electrode material, helping to evenly distribute the pressure, reduce product surface defects, improve surface smoothness and flatness, and can adapt to the processing requirements of different materials; The bending deformation of the roller during operation is corrected by the bending correction mechanism to ensure its straightness and precision, improve product quality and extend roller life; The belt threading mechanism facilitates the negative electrode material to pass between the upper roller and the lower roller, optimizes the loading steps, and improves the loading efficiency; The coarse particles on the upper roller and the lower roller are removed by the adjustable scraper on the scraper mechanism, and when the upper roller and the lower roller are cleaned, the cleaning liquid on the upper roller and the lower roller is scraped off by the scraper rubber knife, so as to achieve rapid liquid removal on the upper roller and the lower roller and avoid spilling of the cleaning liquid everywhere; The tightness of the wiping roller cloth is adjusted by the upper and lower retracting and extending components of the wiping roller mechanism, and the wiping roller cloth rotates in the opposite direction with the upper roller and the lower roller at a low speed respectively, and cooperates with the spray component to clean the roller surface of the upper roller and the lower roller, actively wipe off the dust particles adhering to the roller surface, and keep the roller surface clean. The rubber roller of the wiping roller assembly moves, which can not only drive the wiping roller cloth to fit closely with the upper roller and the lower roller during cleaning, but also separate the wiping roller cloth from the upper roller and the lower roller when the machine is working, so as to avoid interfering with the normal operation of the machine.

10. A working method of a roller press with an automatic spraying and wiping roller structure according to claim 9, characterized in that: The specific steps of this working method are as follows: Step 1: fix the end of the negative electrode sheet on the feeding rod (35) of the belt threading mechanism (15), drive the manual roller (31) to rotate by turning the handle (36), and then drive the chain (34) to transmit on the end sprocket (32) and the installation sprocket (33), at which time the negative electrode sheet moves with the feeding rod (35) and passes between the upper roller (6) and the lower roller (7), completing the feeding work; Step 2: The first motor (13) is operated, the first reducer (12) is speed-regulated, and the upper roller (6) and the lower roller (7) are driven to rotate through the universal coupling (14), and the negative electrode sheet is subjected to roller pressing. The bending cylinder seat (10) is driven to rotate through the telescopic movement of the bidirectional cylinder (11), thereby correcting the bending deformation of the upper roller (6) and the lower roller (7) during operation. At the same time, the second movable inclined iron (26) is driven to rotate between the top inclined iron (21) and the lower inclined iron (25). The first movable bevel iron (24) moves between the first movable bevel iron (24), and the linear bearing (19) and the optical axis (20) cooperate and guide to achieve coarse adjustment of the gap between the upper roller (6) and the lower roller (7). The second motor (29) works, and the second reducer (28) adjusts the speed to drive the fine adjustment screw rod (23) to rotate, thereby driving the first movable bevel iron (24) to move between the second movable bevel iron (26) and the gap adjustment base plate (18), thereby achieving fine adjustment of the gap between the upper roller (6) and the lower roller (7); Step 3: When the processing is completed, the coarse particles on the surface of the upper roller (6) and the lower roller (7) are removed by the scraper mechanism (16), and the first regulating cylinder (38) is extended to drive the flip plate (39) to rotate until the scraper (40) contacts the upper roller (6) and the lower roller (7). At this time, the telescopic cylinder (42) works to drive the scraper rubber knife (41) to be retracted into the flip plate (39). As the upper roller (6) and the lower roller (7) rotate, the scraper (40) scrapes the coarse particles on the surface of the upper roller (6) and the lower roller (7); Step 4: The wiping cloth (48) on one of the air expansion shafts (47) is connected to the other air expansion shaft (47) through the aluminum guide roller (55) and the rubber roller (58), and the second regulating cylinder (56) drives the shaft seat (57) and the rubber roller (58) to move until the wiping cloth (48) is pressed against the roller surfaces of the upper roller (6) and the lower roller (7), and the air expansion shaft (47) is driven to rotate by the third motor (50) to reel up the wiping cloth (48), and the wiping cloth (48) rubs over the upper roller (6) and the lower roller (7) at a low speed, and at the same time, the electric slide rail (51) drives the slide frame (52) and the nozzle (53) to move, and the cleaning liquid is evenly sprayed to the upper roller (6) and the lower roller (7). On the wiping roller cloth (48), the upper roller (6) and the lower roller (7) respectively move in the opposite direction with the wiping roller cloth (48) at a low speed to clean the entire roller surface. During cleaning, the second regulating cylinder (56) contracts, and the telescopic cylinder (42) drives the scraper rubber knife (41) to extend from the flip plate (39). The position of the flip plate (39) is adjusted by the first regulating cylinder (38) to ensure that the scraper rubber knife (41) is in contact with the upper roller (6) and the lower roller (7), and the scraper (40) is separated from the upper roller (6) and the lower roller (7). The cleaning liquid on the upper roller (6) and the lower roller (7) is scraped off by the scraper rubber knife (41).
