Description

Technical Field

[0001] This utility model relates to the field of battery electrode manufacturing, and in particular to a swing roller mechanism for an electrode roller press. Background Technology

[0002] After coating and drying, the peel strength between the active material and the current collector foil is very low. Therefore, the electrodes need to be rolled to enhance the adhesion between the active material and the foil, preventing peeling during electrolyte immersion and battery use. Simultaneously, electrode rolling can compress the cell volume, increase the cell energy density, reduce the porosity between the active material, conductive agent, and binder within the electrode, and lower the battery resistance, thus improving battery performance.

[0003] In current electrode processing technology, two-roll presses are commonly used to roll the electrodes. In order to maintain stable tension when the electrodes enter and exit the press, floating swing roller mechanisms are provided at the inlet and outlet of the press. Tension compensation is set by adjusting the position of the swing rollers.

[0004] However, in the existing roller presses equipped with swing roller mechanisms, the two ends of the swing roller used for tension adjustment are generally fixed directly to the guide roller support during installation. As a result, the parallelism requirement of the swing roller axis relative to the ground cannot be effectively guaranteed, and the tension of the electrode sheets when entering and exiting the roller press cannot be maintained in a stable state through adjustment. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a swing roller mechanism for an electrode roll press that can be conveniently adjusted to ensure stable swing roller tension by adjusting the parallelism of the swing roller.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a swing roller mechanism for an electrode roller press, including a rotating shaft, a swing roller, a left swing arm and a right swing arm, a spindle is rotatably installed through the swing roller, and cylinder assemblies for driving the rotating shaft are respectively provided at both ends of the rotating shaft. The rear end of the left swing arm is connected to the left end of the rotating shaft, and the rear end of the right swing arm is connected to the right end of the rotating shaft. A left support is adjustablely installed on the inner side of the front end of the left swing arm, and a right support is adjustablely installed on the inner side of the front end of the right swing arm. Self-aligning ball bearings that roll with the spindle are respectively installed in the left and right supports. A set screw seat for adjusting the position of the swing roller in the horizontal or vertical direction is fixed at the front end of the left and right swing arms, and an adjusting screw is connected to each set screw seat.

[0007] Specifically, the set screw seat includes an upper pressure plate and a side pressure plate, both connected with adjusting screws. The adjusting screws on the upper pressure plate press against the upper end face of the left support and the upper end face of the right support to adjust the position of the swing roller in the vertical direction. The adjusting screws on the side pressure plates press against the side end face of the left support and the side end face of the right support to adjust the position of the swing roller in the horizontal direction. The adjusting screws are connected with locking nuts that lock the adjusting screws after adjustment.

[0008] Furthermore, both ends of the rotating shaft are supported by mounted spherical bearings.

[0009] Specifically, the cylinder assembly includes a cylinder seat, a low-friction cylinder, and a connecting arm. The mounting end of the low-friction cylinder is movably connected to the cylinder seat. The piston rod of the low-friction cylinder is connected to a spherical bearing. The spherical bearing is movably connected to the front end of the connecting arm via a connecting pin. The rear end of the connecting arm is fixedly connected to the shaft end of the rotating shaft.

[0010] Furthermore, the rear end of the left swing arm is connected to the left end of the rotating shaft via a transmission key, and the rear end of the right swing arm is connected to the right end of the rotating shaft via a tensioning sleeve.

[0011] Furthermore, ball bearings are installed inside both ends of the swing roller, the spindle is engaged with the inner ring of the ball bearing, and positioning sleeves for fixing the ball bearings are provided on the outer sides of both ends of the swing roller.

[0012] The beneficial effects of this utility model are: by adjusting the left and right supports in the horizontal or vertical direction using the adjusting screws on the top screw seats on both sides of the swing roller, the parallelism of the swing roller can be adjusted. The structure is simple and the adjustment is convenient. Attached Figure Description

Ball bearings are installed inside the two ends of the swing roller cylinder 2, and the spindle 5 cooperates with the inner ring of the ball bearing. Positioning sleeves 19 for fixing the ball bearings are provided on the outer sides of the two ends of the swing roller cylinder 2. The rear end of the left swing arm 3 is connected to the left end of the rotating shaft 1 through a transmission key, and the rear end of the right swing arm 4 is connected to the right end of the rotating shaft 1 through a tensioning sleeve 18.

[0022] At both ends of the rotating shaft 1, there are cylinder assemblies that drive the rotating shaft 1 to rotate. The cylinder assembly includes a cylinder seat 13, a low-friction cylinder 14 and a connecting arm 15. The mounting end of the low-friction cylinder 14 is movably connected to the cylinder seat 13. The piston rod of the low-friction cylinder 14 is connected to a spherical bearing 16. The spherical bearing 16 is movably connected to the front end of the connecting arm 15 through a connecting pin 17. The rear end of the connecting arm 15 is fixedly connected to the shaft end of the rotating shaft 1.

The adjusting screw 10 on the side pressure plate 9-2 presses against the side end face of the left support 6 and the side end face of the right support 7 to adjust the horizontal position of the swing roller 2. Each adjusting screw 10 is connected to a locking nut 11 for locking the adjusting screw 10 after adjustment.
