Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paste shaping device for a lead-acid battery plate, which shapes the paste filled in the main body of the plate when manufacturing the lead-acid battery plate.

Plate plates for lead-acid batteries are made by filling an electrode frame body made of an electrode base made of lead or a lead alloy and a synthetic resin frame body with a lead oxide paste to form the main body of the plate. A mat body made of woven or non-woven fabric is welded to both sides of the main body. Conventionally, when manufacturing this type of electrode plate, 1
A pair of paste shaping rollers are opposed to each other, and the paste is shaped between the paste shaping rollers by passing through the electrode plate main body filled with paste, and then the mat body is welded to the synthetic resin portion of the electrode plate main body. However, simply shaping the paste with a paste shaping roller cannot avoid leaving paste on the synthetic resin part that is the main part of the electrode plate. There was a drawback that the welding strength was significantly impaired and the capacity performance and life of the battery were reduced.

An object of the present invention is to provide a paste shaping device for a lead-acid battery electrode plate that eliminates the above-mentioned drawbacks by scraping off the paste adhering to the synthetic resin portion of the electrode plate after shaping the paste.

Embodiments of the present invention will be described in detail below with reference to the drawings.

Figures 1 and 2 schematically show an example of the structure of the electrode plates of a lead-acid battery. In these figures, 1 is a grid-shaped electrode base 2 made of lead or a lead alloy.
The electrode frame body is formed by integrating a frame body 3 made of synthetic resin and a frame body 3 made of synthetic resin, and 2a is an ear portion protruding from the end of the electrode base body 2. The electrode frame 1 is filled with a paste 4 made of lead oxide, and the electrode frame 1 and the paste 4 constitute an electrode main body 5. Both sides of the electrode main body are covered with mat bodies 6 that press the paste 4. It is being said. The mat body 6 is made of a woven fabric or a non-woven fabric, and is heat-welded to the synthetic resin frame 3 that constitutes a part of the electrode main body 5.

The paste shaping device of the present invention has the above-mentioned electrode plate main body 5.
A device for shaping the paste filled in the container,
The configuration of its main parts is schematically shown in FIGS. 3 and 4. In FIG. 3, reference numerals 11 and 11 are a pair of first shaping rollers arranged opposite to each other;
2 and 12 are a pair of second shaping rollers that are similarly arranged opposite to each other. A cloth 13 for preventing the paste 4 from adhering to the outer peripheries of these first and second shaping rollers 11, 11 and 12, 12 is tightly attached. A pair of opposing paste scraping rotating bodies 14, 14 are disposed on the extension of the second shaping rollers 12, 12. These paste scraping rotors are composed of a boss portion 16 and a plurality of blades 15 arranged radially and attached to the boss portion 16. As shown in FIG. 4, each blade 15 has a flat claw portion 15a whose tip abuts against the synthetic resin frame 3 of the electrode plate main body 5, and a substantially semi-cylindrical cross-section projecting from the frame 3. Avoidance recesses 15b formed to avoid the paste portion are alternately provided on one side of the main plate 5 side. The paste scraping rotors 14, 14 scrape off the paste while rotating relative to the paste surface, and are rotationally driven by a drive source (not shown). In this embodiment, as shown by arrows in FIG.
It is designed to be rotated in the direction opposite to the movement of.

When manufacturing an electrode plate using the apparatus of the present invention constructed as described above, as shown in FIG. The paste is inserted between the first shaping rollers 11 and 11 and between the pair of second shaping rollers 12 and 12 to shape the paste. Next, the plate main body 6 that has passed through each shaping roller is passed between a pair of rotationally driven paste scraping rotors 14, 14 to scrape off excess paste adhering to the synthetic resin portion of the plate main body 6. At this time, paste scraping rotating body 1
The paste scraped off by the rotors 4 and 14 is forcibly moved in a direction away from the main plate body 6 by the rotation of the rotors 14 and 14. Therefore, the scraped paste does not accumulate between the rotating body and the main electrode plate, and the paste can be scraped off smoothly. In this way, the electrode main body 6
Next, a mat body is welded to the main body of the electrode plate from which the paste adhering to the synthetic resin portion has been removed.

As described above, according to the present invention, after the paste mainly consisting of the electrode plate is shaped by the shaping roller, the excess paste adhering to the synthetic resin portion of the electrode plate is scraped off by the paste rotor, so that the paste of the mat body is This has the advantage that the welding strength can be increased when welding to the main electrode plate, and the capacity performance and life of the battery can be improved. In particular, in the present invention, since the paste is scraped off by the rotation of the paste scraping rotary body, the scraped paste can be scattered in the direction away from the main electrode plate by the rotation of the rotary body, and the paste can be scraped off by rotating the paste scraping rotary body. Work can proceed smoothly.
