Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lead-acid battery production technology, and in particular relates to an acid injection mechanism for a negative pressure acid filling system for lead-acid batteries. Background Technology
[0002] In the manufacturing process of lead-acid batteries, each cell needs to be filled with acid. Because the sealed cell has a small volume and contains gas, direct filling is time-consuming and difficult to implement. Therefore, a negative pressure acid filling system is usually used to fill lead-acid batteries with acid.
[0003] Currently, in existing negative pressure acid filling systems, the multiple acid injection heads of the injection mechanism are typically fixed, meaning the distance between adjacent injection heads is not adjustable. Therefore, when filling lead-acid batteries of different sizes, the injection mechanism may need to be replaced. This not only affects the acid filling efficiency of the lead-acid batteries but also increases the operating cost of the negative pressure acid filling system and impacts the production efficiency of lead-acid batteries. Therefore, there is an urgent need to research an acid injection mechanism for a negative pressure acid filling system for lead-acid batteries to solve the above problems. Utility Model Content

In use, depending on the size of the lead-acid battery, the adjusting component 5 drives the slider 4 to slide on the guide rail 3, causing multiple sliders 4 to be evenly distributed on the guide rail 3, thereby adjusting the spacing between multiple acid filling heads 6. This ensures that multiple acid filling heads 6 meet the acid filling requirements of the lead-acid battery, which not only guarantees the acid filling efficiency of the lead-acid battery, but also reduces the operating cost of the negative pressure acid filling system. It also ensures the production efficiency of lead-acid batteries and can be applied to the acid filling needs of lead-acid batteries of different sizes.
[0025] Example 2:
[0026] Based on Example 1, as follows Figure 3-4 As shown, the adjustable assembly 5 includes a mounting base 501 bolted to one side edge of the support frame 2 and a guide rod 502 horizontally positioned below the support frame 2; a conventional cylinder 503 is horizontally bolted to the mounting base 501; the extension direction of the output end of the cylinder 503 is parallel to the length direction of the guide rail 3; the output end of the cylinder 503 slides through the mounting base 501 and is bolted to a transmission strip 504; one end of the transmission strip 504 is slidably sleeved on the outer periphery of the guide rod 502; both ends of the guide rod 502 are bolted to opposite sides of the support frame 2; multiple directional blocks 505 corresponding to sliders 4 are slidably sleeved side by side on the guide rod 502; the multiple directional blocks 505 are bolted to the multiple sliders 4; adjacent two directional blocks 505 are connected by a tension spring 506; the tension spring 506 is sleeved on the guide rod 502; the tension spring 506 is always in a compressed state; one surface of a certain directional block 505 abuts against one end of the transmission strip 504. In use, the cylinder 503 drives the transmission plate 504 to move linearly, causing the transmission plate 504 to slide on the guide rod 502. Due to the elasticity of the tension spring 506, the directional block 505 also slides on the guide rod 502. The directional block 505 drives the slider 4 to slide on the guide rail 3. Due to the uniformity of the elastic force of the tension spring 506 on the directional block 505, it is possible to achieve equidistant adjustment of multiple sliders 4, effectively ensuring the position adjustment effect of the acid injection head 6.

Then, the lower surface of the limiting nut 603 is attached to the upper surface of the limiting block 8 by rotating the limiting nut 603, thereby installing the acid injection head 6 on the limiting block 8. This facilitates the installation or removal of the acid injection head 6 and effectively ensures the performance of the negative pressure acid injection system.
