Description

Technical Field

[0001] The utility model relates to the technical field of lead-acid battery production, in particular to a continuous casting grid belt structure. Background Art

[0002] As an energy storage device, batteries are widely used in modern society. The core component of batteries is the grid. The grid belt is generally produced by continuous casting and rolling.

[0003] The patent document with application number CN202121984732.0 and titled "A Battery Continuous Casting and Rolling Grid Structure" discloses a battery continuous casting and rolling grid structure that can improve the processing efficiency of the grid body. The tool only needs to cut in a straight line, which can ensure the cutting quality, reduce the burrs on the pole ears, and ensure the processing quality of the grid body. In the continuous casting production of battery grids, the grids are not strong enough, and they will bend and stretch during the continuous casting process. The existing process is to reduce this situation by adding calcium, but for the positive grid, if calcium is added, it will affect the activity of the grid, and then affect the performance of the battery.

[0004] The patent document with application number CN202222461550.6 and titled "A Continuous Casting Grid Mesh Belt Structure" discloses a method of increasing the strength of the traction parts on both sides to make them less likely to deform, thereby ensuring that the moving speed of the traction parts on both sides is consistent, realizing continuous casting and rolling production of the grid, and reducing the defective rate of the continuous casting grid mesh belt structure. The method of increasing the strength of the traction parts on both sides is: embedding reinforcing ribs in the traction part to increase the strength of the traction part. However, embedding reinforcing ribs in the traction part will increase the production cost, and the reinforcing ribs need to be removed when the mesh belt waste is recycled, thereby increasing the cost of subsequent mesh belt waste recycling. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a continuous casting grid mesh belt structure which can improve the traction strength of the mesh belt traction part and reduce the subsequent recycling cost.

[0006] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0007] The continuous casting grid mesh belt structure includes a plurality of parallelly arranged traction bars, wherein two adjacent traction bars are connected by a plurality of connecting bars, the connecting bars are perpendicular to the traction bars, a plurality of grids are arranged between the two adjacent traction bars, the plurality of grids are evenly distributed along the length direction of the connecting bars, the grids are connected to the connecting bars, the thickness of the traction bars is greater than the thickness of the grids, the grids are connected to the traction bars on one side thereof by a plurality of external connecting blocks, and the two adjacent grids are connected by a plurality of internal connecting blocks.

[0008] Specifically, the thickness of the inner connecting block is equal to that of the outer connecting block, and the thickness of the traction strip is equal to that of the inner connecting block.

[0009] Specifically, the plurality of grids are arranged in a linear array along the length direction of the connecting strip.

[0010] Specifically, two adjacent grids in the length direction of the connecting strip are arranged inverted.

[0011] Specifically, the lower end of the connecting strip has a groove, the upper end of the connecting strip has a protrusion, the length direction of the groove is parallel to the length direction of the protrusion, and the length direction of the groove is parallel to the length direction of the connecting strip.

[0012] Specifically, the thickness of the traction strip is 1.5 to 2 times the thickness of the grid.

[0013] Specifically, the thickness of the connecting strip is equal to the thickness of the traction strip.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model can improve the overall structural strength of the mesh belt by increasing the thickness of the traction strips and the connecting strips, so as to make the traction speeds on both sides of the mesh belt consistent and reduce the probability of deformation of the grid during movement.

[0016] 2. When recycling waste materials, the mesh belt can directly enter the smelting furnace for smelting, which can reduce the recycling cost.

[0017] 3. The cutter only needs to cut in a straight line, which can improve the processing efficiency of the grid body. The lower ends of the connecting strip, the lower ends of the traction strip, the lower ends of the inner connecting block and the lower ends of the outer connecting block are flush, which can avoid deformation of the grid during cutting.

[0018] 4. After the connecting strip is punched, a protrusion and a groove are formed, which increases the structural strength of the connecting strip. When cutting the grid, the deformation of the connecting strip can be avoided, and the flatness of the grid cut can be ensured. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0033] Example 1: Reference Figure 1-Figure 4 As shown, the continuous casting grid mesh belt structure includes a plurality of parallel traction bars 1, wherein two adjacent traction bars 1 are connected by a plurality of connecting bars 2, the connecting bars 2 are perpendicular to the traction bars 1, and a plurality of grids 4 are arranged between two adjacent traction bars 1.

[0034] The plurality of grids 4 are evenly distributed along the length direction of the connecting strip 2. Specifically, the plurality of grids 4 are linearly arrayed along the length direction of the connecting strip 2.

[0035] The grid 4 is connected to the connecting bar 2. The lower end of the connecting bar 2 has a groove 7, and the upper end of the connecting bar 2 has a protrusion 3. The length direction of the groove 7 is parallel to the length direction of the protrusion 3, and the length direction of the groove 7 is parallel to the length direction of the connecting bar 2. The thickness of the connecting bar 2 is equal to the thickness of the traction bar 1.

[0036] The thickness of the traction bar 1 is greater than the thickness of the grid 4. Specifically, the thickness of the traction bar 1 is 1.5 to 2 times the thickness of the grid 4.

[0037] The grid 4 is connected to the traction bar 1 on one side thereof by a plurality of external connection blocks 5, and two adjacent grids 4 are connected by a plurality of internal connection blocks 6. Specifically, the thickness of the internal connection blocks 6 and the external connection blocks 5 are equal, and the thickness of the traction bar 1 is equal to the thickness of the internal connection blocks 6.

[0038] The mesh belt improves the structural strength of the mesh belt by increasing the thickness of the traction strip 1, the connecting strip 2, the inner connecting block 6 and the outer connecting block 5, so as to make the traction speed on both sides of the mesh belt consistent and reduce the probability of deformation of the grid 4 during movement.

[0039] The lower ends of the connecting strip 2, the lower ends of the pulling strip 1, the lower ends of the inner connecting block 6 and the lower ends of the outer connecting block 5 are flush with each other. The grid 4 can be prevented from being deformed during cutting.

[0040] When cutting, the tool only needs to cut in a straight line, which can improve the processing efficiency of the grid 4 body. Figure 2 As shown, the cutter can directly and linearly cut the connection between the pole ear of the grid 4 and the connecting strip 2 on one side, the connection between the bottom of the grid 4 and the connecting strip 2 on one side, and the connection between the grid 4 and the external connecting block 5 on one side. After completing the above cutting action, multiple grids 4 are connected together through the internal connecting block 6 to form a grid sheet. Then, the grid 4 is obtained by cutting the connection between the grid 4 and the internal connecting block 6.

[0041] After the connection strip 2 is punched, a protrusion 3 and a groove 7 are formed, the structural strength of the connection strip 2 is increased, deformation of the connection strip 2 can be avoided when cutting the grid 4, and the flatness of the cut of the grid 4 can be ensured.

[0042] Embodiment 2: Based on Embodiment 1, refer to Figure 5 As shown, two adjacent grids 4 in the length direction of the connecting strip 2 are arranged inverted.

[0043] Due to the structural characteristics of the grid 4, the connection area between the pole ear of the grid 4 and the connecting strip 2 on one side is small, while the connection area between the bottom of the grid 4 and the connecting strip 2 on one side is large. By inverting the two adjacent grids 4 in the length direction of the connecting strip 2, the structural strength of the mesh belt can be further improved, and the probability of deformation can be reduced when the mesh belt is pulled.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
