Secondary sealing machine for battery

The utility model provides a secondary sealing machine for a battery, which comprises a vacuumizing packaging mechanism, the vacuumizing packaging mechanism comprises a liquid receiving tank, the liquid receiving tank is provided with a liquid flow hole, and the liquid flow hole is connected with a vacuumizing device. By adopting the technical scheme of the utility model, the liquid flowing hole of the liquid receiving tank is improved, and electrolyte can quickly flow out of the liquid receiving tank and enter the vacuum pipeline during secondary sealing air exhaust, so that the liquid receiving tank cannot be blocked. And the improved liquid receiving tank can be cleaned once every 3-5 days, so that the cleaning is more convenient, and the production efficiency is improved. 本实用新型提供了一种电池用二封机，其包括抽真空封装机构，所述抽真空封装机构包括接液槽，所述接液槽设有液流孔，所述液流孔与抽真空装置连接。采用本实用新型的技术方案，对接液槽流液孔洞进行了改良，在二封抽气时电解液能快速流出接液槽并进入真空管道内，使接液槽不会出现堵塞。而且改良后的接液槽可以3-5天清理一次，清理起来更加方便，提高了生产效率。
