Description

Zinc paste injection machine for alkaline manganese cell

The invention relates to an automatic paste injection device for injecting cathode zinc paste into a battery diaphragm sleeve in the production of an alkaline zinc-manganese battery (an alkaline manganese battery for short).

The alkaline manganese battery is a high-performance battery which is developed recently in recent years, is a new product upgraded and updated internationally, has the advantages of large output power, large capacity, good discharge performance, strong low-temperature performance and the like, and has a fast development speed since the advent.

The zinc paste injection process of the alkaline manganese battery is an important link for producing the alkaline manganese battery, and directly influences the performance and quality of the battery. At present, most manufacturers of alkaline manganese batteries (except for introducing a complete production line) in China basically adopt a manual injection method for the zinc paste injection process (see figure 4). When pouring the zinc cream, a worker carries the glass thin rod to reciprocate up and down in the funnel by hand, holds the battery shell by the other hand, aligns the inner opening of the diaphragm sleeve with the discharge spout of the funnel, and the zinc cream is poured into the diaphragm sleeve along with the up-and-down movement of the glass thin rod. In the paste injection process, a worker needs to move the battery case out of the discharge spout several times, and the zinc paste is solidified on the iron block or the wood block, otherwise, the sufficient injection is difficult. The manual paste injection has low production efficiency and high labor intensity of workers, and the injection amount of the zinc paste is mastered by the experience of the workers, so that the paste injection precision cannot be ensured.

In an LR6 battery production line used by Japan Songdahu electric company, a plurality of glass thin tubes are utilized in the process of injecting the zinc paste, and the processes of extracting the paste, lifting, transposition and injecting the paste are realized, so that the machine has high manufacturing cost (about 20 ten thousand dollars), the glass thin tubes are easy to break, the occupied area is large, accessories are not easy to purchase, and faults are not easy to remove.

The hinge portion of the lever 19 has a hinge pin slot.

The left end of the pumping and injecting lever 19 is a mandril 7, the mandril 7 is provided with an adjusting sleeve nut 14 for adjusting the length of the mandril so as to adjust the stroke of the pumping and injecting rod 12 of the pumping and injecting mechanism, thereby controlling the capacity of pumping and injecting the zinc paste, the lower part of the mandril 7 is contacted with a cam 6 on a distribution shaft 37 through a roller, when the cam 6 rotates to jack up one end of the pumping and injecting lever 19 through the mandril 7, a group of pumping and injecting zinc paste mechanisms on the upper part of a material groove 13 pump the zinc paste; while a set of pumping mechanisms on the upper part of the carrier plate 28 injects the zinc paste into the battery diaphragm sleeve, and pumping and injecting are carried out simultaneously. And because the distances from the fulcrum seat 20 of the pumping lever 19 to the pumping mechanisms at the two ends are equal, the capacities of the two groups of pumping mechanisms for pumping paste and injecting paste are equal.

The pumping and injecting rod 12 and the needle tube 11 of the pumping and injecting zinc paste mechanism are made of plastics, are not easy to break and are convenient to replace.

The kingpin 21 is driven in intermittent indexing motion by a geneva gear 36, 35 on the motion distribution shaft and a pair of bevel gears 33, 32. In order to ensure that the nozzle 11 is aligned with the correct position of the battery diaphragm pocket in the carrier plate 28 during paste injection, the machine is provided with a positioning device. The rotating arm 22 is provided with a positioning block 24, a positioning head 23 is matched with the rotating arm, the positioning head 23 is connected with a sliding rod 26, the sliding rod 26 is controlled to move through the swinging of a swinging rod 27 to realize the positioning movement, and the swinging of the swinging rod 27 is generated by the rotation of the end face cam 1 at the lower end of the swinging rod 27; the head of slide bar 26 has a roller directly attached to it to position carrier plate 28.

The cam 5 rotates, the chute 13 is jacked up through the roller and the bracket 8 to realize that the head of the needle tube 11 is inserted into the zinc material to extract the zinc paste, after the zinc paste is sufficiently extracted, the chute 13 descends under the action of self weight, and the rotating arm 22 starts to rotate.
