Pre-flattening device of thin-film capacitor winding machine

Abstract

The invention discloses a pre-flattening device of a thin-film capacitor winding machine. The device comprises a machine body and a fixing frame, the fixing frame is installed at the upper end of the machine body, a left rolling belt is rotatably connected to the interior of the upper end of the fixing frame, a right rolling belt is rotatably connected to the interior of the upper end of the fixing frame, the left rolling belt is attached to the right rolling belt, and a conveying frame is fixed to the upper end of the machine body; by adopting the mode that a gear is matched with an alignment toothed rod, when the fixing rod on the working left side of the pre-flattening device moves upwards, the fixing rod can make contact with a ratchet wheel to drive a threaded rod to rotate, meanwhile, a connecting rod on the pre-flattening device can also drive the threaded rod to rotate through a transmission gear, and the fixing rod and the connecting rod drive the threaded rod to rotate in opposite periods, the rotating time is complementary, the threaded rod rotates to push a push plate to reciprocate along with a threaded sleeve, machined materials on the fixing frame are pushed away and reset, automatic treatment on the materials after pre-flattening is achieved, the automation degree of the pre-flattening device is higher, and the pre-flattening device is more convenient to use.

Description

technical field [0001] The invention belongs to the technical field related to film capacitors, and in particular relates to a pre-flattening device of a film capacitor winding machine. Background technique [0002] Film capacitors use metal foil as an electrode, which is overlapped with plastic films such as polyethylene, polypropylene, polystyrene or polycarbonate from both ends, and then wound into a cylindrical capacitor. The film capacitor is wound Machine winding production, the internal winding of the film capacitor produced is not tight enough, which will affect the normal use of the film capacitor, and the internal gap needs to be squeezed by a hot press, but because the film capacitor is in the shape of a cylinder after winding, it will The surface of the press will roll, which is inconvenient for alignment and extrusion, and it needs to be placed neatly manually to prevent adjacent capacitors from sticking together after extrusion and cannot be used normally. For ...
