Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery technology, and in particular relates to a curing and drying rack for tubular extrusion plates. Background Technology

[0002] Lead-acid batteries are a common chemical power source, widely used in automobiles, power, and energy storage. Tubular plates are a type of lead-acid battery plate and a key component of lead-acid batteries. The manufacturing process of tubular plates involves first forming an alloy grid, then inserting the lead reinforcing bars of the grid into tubing, loading the active material into the tubing using specific production methods, and finally sealing the bottom.

[0003] There are two main production methods for tubular electrode plates: powder filling and paste extrusion. Powder filling produces more dust and does not meet environmental protection requirements. In contrast, paste extrusion has the advantages of less pollution and less noise. Therefore, mainstream manufacturers mainly use paste extrusion to produce tubular electrode plates.

[0004] During normal production, the tubular plates after extrusion are placed on a curing and drying rack in a curing chamber for curing and drying. Existing curing and drying racks are basically used to place the plates vertically, keeping them suspended in the air. Under the influence of gravity, this placement method causes the active material in the upper part of the tubular extrusion plate tubes to tend to move downwards, resulting in a certain difference in the density of active material in the upper and lower tubes of the tubular plate. This difference has an adverse effect on the tubular extrusion plate, and consequently, on the battery performance. Utility Model Content

[0005] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0006] A curing and drying rack for tubular extruded electrode plates includes four columns. Every two columns are connected by horizontal support bars to form a cube or cuboid curing and drying rack. Several vertical support bars are fixedly connected between the two horizontal support bars. Electrode plate placement slots for placing tubular extruded electrode plates are fixedly installed on both sides of the vertical support bars and on the side of the column near the vertical support bars.

[0007] As a preferred embodiment of the above technical solution, a corner pad is fixedly connected to the top of the column, and the bottom of the corner pad is the same size as the bottom of the column.

[0008] As a preferred embodiment of the above technical solution, the top of the column is provided with a groove, the bottom of the pad corner is provided with a through opening of the same size as the groove, and the bottom of the column is provided with a retractable positioning shaft, the size of which is the same as that of the through opening and the groove.

[0009] As a preferred embodiment of the above technical solution, the bottom end of the column is provided with a storage groove, and an elastic element is installed inside the storage groove. The elastic element is fixedly connected to the positioning shaft.

[0010] As a preferred embodiment of the above technical solution, a threaded hole communicating with the groove is provided on one side of the column. A fastening bolt is threadedly connected to the threaded hole, and a knob and an anti-slip pad are respectively fixedly connected to both ends of the fastening bolt. The anti-slip pad is located inside the groove.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The curing and drying rack of this utility model eliminates the original false tabs of the tubular extrusion plate, reduces the material cost in the manufacturing process, and reduces the process of removing false tabs, thus saving labor costs;

[0013] 2. The tubular extruded electrode plate of this utility model is placed parallel to the ground, which makes the overall density of the extruded electrode plate more uniform, which is beneficial to the performance of the battery.

[0014] 3. The electrode plate placement groove of this utility model has a reasonable placement gap, which is conducive to the curing and drying of the tubular extrusion electrode plate and improves the consistency of the electrode plate curing and drying process. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] Example

[0022] like Figure 1 , Figure 2 and Figure 3As shown, the curing and drying rack for tubular extruded electrode plates includes four columns 1. Every two columns 1 are connected by horizontal support bars 5 to form a cube or cuboid curing and drying rack. Several vertical support bars 6 are fixedly connected between two horizontal support bars 5. Electrode plate placement slots 8 for placing tubular extruded electrode plates are fixedly installed on both sides of the vertical support bars 6 and on the side of the column 1 near the vertical support bars 6. A pad 3 is fixedly connected to the top of the column 1. The bottom of the pad 3 is the same size as the bottom of the column 1. A baffle 7 is provided at the center of the horizontal support bars 5 and the vertical support bars 6.

[0023] Specifically, there are four uprights 1, perpendicular to the ground along the four sides of the curing and drying rack, serving as the main support columns and providing overall support. Corner pads 3 are at the top of uprights 1, allowing the curing and drying racks to be stacked. Horizontal support bars 5 are on the front, back, and two sides, with three on each side, distributed at the top, middle, and bottom, primarily for lateral support to ensure the lateral stability of the curing and drying rack. Vertical support bars 6 are three on the front and back, and one at the center of each side, primarily for vertical support to ensure the vertical stability of the curing and drying rack. Baffles 7 are at the center of both front and back, primarily for spacing, allowing for the placement of tubular extrusion plates on both sides, increasing the number of plates that can be placed. Plate placement slots 8 are fixed inside the curing and drying rack, mainly used to place the extruded tubular plates. The pull-out design ensures the overall balance of the plates with the ground, preventing gravity from causing differences between the upper and lower parts of the tubular plates. During the manufacturing process, the tubular electrode plates after the paste is extruded can be directly inserted into the electrode plate placement slot 8.

[0024] like Figure 1 and Figure 2 As shown, the top of the column 1 has a groove 2, the bottom of the pad corner 3 has a through hole 4 of the same size as the groove 2, and the bottom of the column 1 is equipped with a retractable positioning shaft, the size of which is the same as the through hole 4 and the groove 2.

[0025] Specifically, it allows for easy assembly of the bottom of one column 1 with the top of another column 1 for stacking, thus reducing the floor space required.

[0026] like Figure 2 As shown, a storage groove is provided at the bottom of the column 1, and an elastic element is installed inside the storage groove. The elastic element is fixedly connected to the positioning shaft.

[0027] It should be noted that the combination of the storage slot and the positioning shaft makes the two columns 1 stacked together less likely to collapse, resulting in high stability.

[0028] like Figure 2As shown, a threaded hole communicating with the groove 2 is provided on one side of the column 1. A fastening bolt is threaded into the threaded hole. A knob and an anti-slip pad are fixedly connected to both ends of the fastening bolt, and the anti-slip pad is located inside the groove 2.

[0029] It should be noted that the rubber pad is made of, but is not limited to, rubber. The distance between the anti-slip pad and the positioning shaft is controlled by rotating the fastening bolt. When the anti-slip pad and the positioning shaft are tightly fitted together, the friction between them is increased, making it difficult for the anti-slip pad to be pulled out of the groove 2.

[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
