Description

Technical Field

[0001] The utility model relates to the technical field related to battery production, in particular to a lead-acid battery grid paste coating device. Background Art

[0002] The grid is one of the most important components of lead-acid batteries. After the grid is produced, it needs to be filled with lead paste; and the quality of the paste is an important indicator that determines the performance of the battery.

[0003] At present, the plates of domestic lead-acid batteries are generally paste-coated plates. The production steps of paste-coated plates generally include: preparation of lead paste, pressing and filling of lead paste on the grid and drying of lead paste after filling. Pressing and filling of lead paste on the grid generally requires the use of a paste coating machine.

[0004] The existing paste coating machine consists of two paste coating rollers arranged upper and lower for coating, but the size of the paste coating roller is fixed. When coating the grid, the paste coating machine needs to adjust the inlet direction of the grid when coating grids of different sizes. For example, for a large-sized grid, lead paste will be coated on the pole ears of the grid. When coating the grid with a small size, since the size of the rotating roller of the paste coating machine is larger than that of the small-sized grid, the pole ears of the small-sized grid will also be coated with lead paste. Therefore, the lead paste on the pole ears needs to be cleaned, which affects the production efficiency of the grid. Utility Model Content

[0005] The utility model aims to provide a lead-acid battery grid paste coating device, which can solve the problem that the traditional battery grid paste coating device cannot coat grids of different sizes with paste.

[0006] To this end, the technical solution adopted by the utility model is: a lead-acid battery grid pasting device, comprising two rotating rollers spaced apart in an upper and lower manner, a feed conveyor belt and a discharge conveyor belt are respectively arranged on the front and rear sides of the rotating roller, the feed conveyor belt is positioned higher than the rotating roller located below, and the discharge conveyor belt is positioned lower than the rotating roller located below, a plurality of annular connecting grooves are arranged at intervals along the axial direction on the rotating roller, a small pasting ring for coating is installed on the annular connecting groove, a connecting block matching the annular connecting groove is arranged on the inner wall of the small pasting ring, the small pasting ring is fixed to the rotating roller by a key and the annular connecting groove, and the middle small pasting ring is fixed in the middle of the rotating roller.

[0007] More preferably, the number of the paste ringlets is an odd number, and the paste ringlets on both sides are symmetrical about the paste ringlet in the middle. When the size of the grid increases, the paste ringlets on both sides are moved toward the middle for paste application on grids of different sizes.

[0008] More preferably, both ends of the discharge conveyor belt are arranged on a rotating shaft, wherein the rotating shaft on the side away from the rotating roller is an output shaft, and both ends of the output shaft are provided with a transmission chain, and the transmission chain is installed between the output shaft and a driven shaft away from the output shaft. After the grid is coated with paste, it enters the transmission chain to facilitate the collection of the grid.

[0009] Further preferably, the transmission chain is fixed on the output shaft and the driven shaft through a rotating wheel, and the spacing between the transmission chains at both ends can be adjusted according to the size of the grid through an adjustment structure. By setting one end of the transmission chain on the output shaft, grid ears of different sizes can fall on the two transmission chains, and the grid can move with the transmission of the transmission chain, which is convenient for the transportation of the grid, and when the grid ears move with the transmission of the transmission chain, the part of the grid coated with paste is suspended in the air, which is convenient for drying the grid after the paste is applied.

[0018] The feed conveyor belt 2 is positioned higher than the rotating roller 1 located below, and the discharge conveyor belt 3 is positioned lower than the rotating roller 1 located below. A plurality of annular connecting grooves 102 are arranged on the rotating roller 1 at intervals along the axial direction, and a small paste ring 101 for coating is installed on the annular connecting groove 102. A connecting block matching the annular connecting groove 102 is arranged on the inner wall of the small paste ring 101. The small paste ring 101 is fixed to the rotating roller 1 by a key and the annular connecting groove 102, and the middle small paste ring 101 is fixedly arranged in the middle of the rotating roller 1.

[0019] Combination Figure 2 and Figure 3 As shown, the sleeve 402 is connected to the rotating wheel 401 by bolts. The size of the sleeve 402 is adjusted according to the size of the grid, so that the rotating wheel 401 can always correspond to the position of the pole ear of the grid, so that it can be suitable for the coating of grids of different sizes. A threaded hole is provided on the annular connecting groove. The paste ring 101 is first installed on the annular connecting groove, and then the annular connecting groove is fixed, and the connecting block of the paste ring 101 is fixed. When the number of paste rings 101 needs to be adjusted, the annular connecting groove is fixed to the middle paste ring 101 with a long bolt to achieve the purpose of coating grids of different sizes.

[0020] The number of the paste ringlets 101 is an odd number, and the paste ringlets 101 on both sides are symmetrical about the middle paste ringlet 101. When the size of the grid increases, the paste ringlets 101 on both sides are moved toward the middle for paste application of grids of different sizes.

[0021] Both ends of the discharge conveyor belt 3 are arranged on the rotating shaft, wherein the rotating shaft on the side away from the rotating roller 1 is the output shaft, and both ends of the output shaft are provided with a transmission chain 4, which is installed between the output shaft and the driven shaft away from the output shaft.
