Feeding equipment for improving paste mixing uniformity

Abstract

The invention provides feeding equipment for improving paste mixing uniformity. The feeding equipment comprises a paste mixing box, wherein the paste mixing box is internally provided with a paste mixing plate; the paste mixing plate is driven by a paste mixing motor arranged at an upper end to rotate to stir a lead paste in the paste mixing box; a feeding sealing door is arranged on the paste mixing box; a proportioning tube is arranged at the upper end of the paste mixing box; one end of the proportioning tube is connected with the upper end of the paste mixing box; the other end of the proportioning tube is provided with an ingredient containing bucket; a powder pump is arranged at the middle section of the proportioning tube; ingredients in the ingredient containing bucket are delivered to the paste mixing box through the powder pump; a feeding valve is arranged at one end where the proportioning tube is connected with the paste mixing box; and proportioning and feeding actions arecontrolled through the feeding valve. In paste mixing, when 20% of lead powder is fed, the powder pump is powered on to work, the ingredients in the ingredient containing bucket are sucked out and are premixed and delivered into the paste mixing box, since a lead pot is sealed in the whole process, lead powder overflowing is not caused, and in addition, the feeding equipment has the characteristics of being uniform in stirring.

Description

technical field [0001] The invention relates to the field of accumulator manufacturing, in particular to a feeding device for improving the uniformity of paste. Background technique [0002] At present, when manufacturing batteries, it is necessary to blend the lead paste. In traditional blending, in order to avoid dust from the lead powder, the ingredients are usually added first, followed by the lead powder, and the automatic blending is turned on. But the mixing of this mode lead powder and batching can not be completely uniform. Another feeding method is to add the ingredients when the lead powder is 20%~30% blanked, and then add the remaining lead powder after blanking and stir. The lead powder in this way is mixed with the ingredients relatively evenly, but because the cover of the paste pot needs to be opened halfway, it will cause the lead powder to fly and endanger the health of the operator. Therefore, it is particularly important to solve the problem that the mi...

Problems solved by technology

[0003] In order to solve the above problems, the purpose of the present invention provides a kind of feeding equipment that improves the homogeneity of the paste, and pastes the lead powder through the paste box, and when the paste is mixed, the powder pump is started to start It works by sucking out the ingredients in the ingredient bucket, premixing them and sending them to the paste box. Since the lead pot is sealed throughout the process, it will not cause the lead powder to overflow, and it has the characteristics of uniform stirring, which solves the problem of lead powder and paste. The working mixing cannot be completely uniform or it is easy to cause the problem of flying lead powder
