Technical Field

The utility model relates to a strip unreels transmission technical field, specifically is an unwinding device convenient to adjustment transmission direction.

Background

The battery pole piece material is formed by one layer of base material and two layers of foil through ultrasonic welding, when welding, the foil needs to be unreeled and transmitted through a foil unreeling mechanism, and the linear speed requirement of the foil unreeling transmission is matched with the linear speed of the base material unreeling transmission. In the case of a strip material, the conveying speed of the strip material needs to be determined according to the roll diameter of the roll material, a distance sensor is usually fixedly arranged at an unreeling station to measure the roll diameter of the roll material, and the distance sensor is usually used for measuring the distance from the sensor to the outermost layer of the roll material to determine the size of the roll diameter.

If the direction of coil placement is different, then the direction of coil transmission is then different, but usually the distance sensor is fixed in certain definite position, if the coil placement is reverse, then the measuring path of distance sensor will be sheltered from in the coil transmission course, just also can't realize the timely effective measurement of coil diameter.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-3, the utility model provides a technical scheme, an unwinding device convenient to adjustment transmission direction, including frame riser 10, logical key formula physiosis axle 20, unreel guide roll 40 and preceding backup pad 30, logical key formula physiosis axle 20 rotates with frame riser 10 and cup joints, be provided with distance sensor 60 on the preceding backup pad 30, the perpendicular fixedly connected with branch 73 in back of preceding backup pad 30, branch 73 connects perpendicularly in the front of frame riser 10, preceding backup pad 30 is located one side position above logical key formula physiosis axle 20, the rear end of unreeling guide roll 40 rotates perpendicularly and cup joints the one end that openly is close to logical key formula physiosis axle 20 at preceding backup pad 30, the positive other end of preceding backup pad 30 rotates perpendicularly and cup joints aluminium roller 50 of rectifying, distance sensor 60 is located the intermediate position of unreeling guide roll 40 and aluminium roller 50 of rectifying.

In this embodiment, the perpendicular fixedly connected with slide rail 11 in back of frame riser 10, slide clamping has movable platform 70 on slide rail 11, the rear end fixed connection of logical key formula physiosis axle 20 in movable platform 70's upper surface, movable platform 70 upper surface still fixed mounting has drive logical key formula physiosis axle 20 pivoted servo motor 90, the perpendicular fixedly connected with riser 71 in rear end of movable platform 70 upper surface, the telescopic cylinder 80 of rectifying is connected with in front of riser 71, the flexible end of the telescopic cylinder 80 of rectifying and the back fixed connection of frame riser 10, backup pad 72 behind one side fixedly connected with on riser 71 top, the rear end of branch 73 runs through behind the back of frame riser 10 with the front fixed connection of backup pad 72, and branch 73 cup joints with frame riser 10 slip.

The working principle is as follows: when the uncoiling device is used, the coiled material is firstly sleeved on the through key type air expansion shaft 20, and the servo motor 90 drives the through key type air expansion shaft 20 to rotate so as to carry out uncoiling operation; if the coiled material is placed correctly, the through-key type inflatable shaft 20 rotates clockwise to unreel, at the moment, the free end of the coiled material sequentially bypasses from the outer side and the top of the unreeling guide roller 40 and then bypasses from the top of the deviation-correcting aluminum roller 50, and at the moment, the detection path of the distance sensor 60 is positioned at the lower right side of the coiled material transmission direction, so that the detection point of the distance sensor 60 can fall on the outermost layer of the coiled material and cannot be shielded; when the coiled material is placed in wrong direction, the through key type air inflation shaft 20 needs to be changed into the operation that the anticlockwise rotation can unreel, the free end of the coiled material is transmitted after being bypassed around the inner side and the top of the deviation rectifying aluminum roller 50 in sequence at the moment, and the detection path of the distance sensor 60 is arranged on the upper left side of the coiled material transmission direction at the moment, so that the detection point of the distance sensor 60 can fall on the outermost layer of the coiled material and cannot be shielded.

When the deviation of the unreeled strip needs to be corrected, the deviation correcting telescopic cylinder 80 is stretched to enable the movable platform 70 to slide back and forth on the slide rail 11, and meanwhile, the through key type air inflation shaft 20 and the support rod 73 are sleeved back and forth relative to the stand plate 10 of the rack, so that the support rod 73 drives the deviation correcting aluminum roller 50 and the unreeling guide roller 40 to move back and forth through the front support plate 30 to finish the deviation correcting process of strip material transmission; the distance sensor 60 is stationary relative to the web throughout the correction process, avoiding deviation of the detection points.
