Description

Technical Field

[0001] The invention relates to the technical field of lead-acid battery plate manufacturing, in particular to a device for preventing thickness differences of continuous coating plates caused by rolling with a leveling roller. Background Art

[0002] Electric bicycles are light and practical, and have been used by more and more urban residents. With the development of science and technology, the automation of lead-acid battery production is getting higher and higher. The extensive use of four-link technology equipment is a full reflection of this. In the development and use of automation equipment, some parts have not reached the optimal state, which gradually emerges in production. The continuous coating plate is slightly curved after slitting because the slitting knife is fixed on the round roller, and the flattening roller behind is required to roll it flat.

[0003] After slitting, the plate is rolled on the conveyor belt, and the leveling roller is on the conveyor belt. The plate is driven by the conveyor belt and rolled by the leveling roller to make the plate surface flat. During rolling, the leveling roller is pressed on the conveyor belt, and the conveyor belt is pressed down in an arc shape with the leveling roller. In this way, there is no gap between the leveling roller and the conveyor belt. The wet plate thickness of the raw plate is greater than 2.0mm, while the grid thickness is only 0.8mm. There is 0.6mm of wet lead paste on the upper and lower frames, and the moisture content is 10%. The wet lead paste is relatively soft. During rolling, the lead paste first enters the frame rolled by the leveling roller and is subjected to rolling extrusion, causing the lead paste to be squeezed and pushed, resulting in a slight pile-up of the squeezed and pushed lead paste, and the surface thickness of the plate is deviated. The plates are stacked together, and the thickness difference on both sides is obvious. After the plate is assembled into the battery, it will cause uneven pressure on the battery pole group, affecting the battery life. The traditional plate flattening device lacks a structure to prevent thickness differences. Summary of the invention

[0027] By arranging a vacuum suction hood 7 under the conveyor belt 6, the interior of the vacuum suction hood 7 is in a negative pressure state, thereby sucking and bending the conveyor belt 6 downward, so that the conveyor belt 6 fits on the lining plate 13 to form an arc-shaped bend. Under the extrusion of the leveling roller 2, the overall thickness of the green plate is kept consistent, avoiding the uneven thickness of the green plate caused by the traditional rolling device when rolling the green plate, thereby affecting the efficiency of the later battery.

[0028] The tensioning assembly 11 includes a support plate 111 arranged at the bottom of the inner cavity of the machine frame 1, and both ends of the support plate 111 are fixed on the inner wall of the machine frame 1. An electric push rod 112 is arranged below the support plate 111, and the electric push rod 112 is installed at the center of the bottom of the support plate 111.

[0032] The vacuum suction hood 7 is located on the inner side of the fixed side plate 8, and the side surface of the fixed side plate 8 is 40 to 50 mm larger than the side surface of the vacuum suction hood 7. By limiting the side dimensions of the vacuum suction hood 7 and the dimensions of the fixed side plate 8, it is ensured that the fixed side plate 8 can seal both sides of the vacuum suction hood 7 to ensure sealing.

[0033] Grooves 20 are provided at the front and rear ends of the top of the vacuum suction hood 7. The sealing shaft 10 rotates in the groove 20 through bearings. The sealing shaft 10 and the vacuum suction hood 7 are sealed by a first foam rubber sheet 21. The grooves 20 are provided at the front and rear ends of the top of the vacuum suction hood 7 to ensure the connection between the sealing shaft 10 and the vacuum suction hood 7. The sealing shaft 10 and the vacuum suction hood 7 are sealed by the first foam rubber sheet 21, and the sealing roller is fitted with the conveyor belt 6 to ensure the sealing of the vacuum suction hood 7. When the vacuum suction hood 7 is in a negative pressure state, the conveyor belt 6 can be adsorbed to make the conveyor belt 6 bend downward.

The driving motor 22 drives the driving roller 3 to rotate, and then the conveyor belt 6 is supported by the driving roller 3, the driven roller 4 and the tensioning roller 5. The rotation of the driving roller 3 can drive the conveyor belt 6 to rotate to transport the green plates.

[0035] Limit rods 23 are fixed on both sides of the bottom of the installation frame 113. The top of the limit rod 23 passes through the support plate 111 and is fixed with a limit ring. A connecting spring 24 is sleeved on the outer side of the limit rod 23. The two ends of the connecting spring 24 are respectively connected to the limit ring and the support plate 111. The setting of the limit rod 23 passing through the support plate 111 facilitates the limiting of the installation frame 113 to avoid shaking of the installation frame 113 during the up and down movement, which affects the tensioning effect of the tensioning roller 5 on the conveyor belt 6. At the same time, the connecting spring 24 can assist in adjusting the up and down movement of the installation frame 113.

[0036] Second foam rubber sheets 25 are bonded to both sides of the vacuum suction hood 7 , and the second foam rubber sheets 25 are attached to the inner wall of the fixed side plate 8 . The second foam rubber sheets 25 are used to improve the sealing between the vacuum suction hood 7 and the fixed side plate 8 .

[0037] During specific use, the drive motor 22 is started, and the drive motor 22 drives the drive roller 3 to rotate, and then the electric push rod 112 drives the installation frame 113 to move downward, so that the tensioning roller 5 tightens the conveyor belt 6, and then the conveyor belt 6 rotates with the cooperation of the drive roller 3, the driven roller 4 and the tensioning roller 5 to convey the green plate. When the green plate is conveyed to the bottom of the leveling roller 2, the conveyor belt 6 is squeezed downward by the green plate and depressed. At the same time, the vacuum suction hood 7 is fitted with the conveyor belt 6 through the sealing shaft 10. When the vacuum joint 9 is used, the vacuum suction hood 7 is in a negative pressure state, and then the conveyor belt 6 bends downward and fits on the lining plate 13. Then the green plate passes between the downward bent conveyor belt 6 and the leveling roller 2, and is squeezed and flattened by the leveling roller 2. During the process, the rolling pressure of the green plate is kept uniform, thereby ensuring the uniform thickness of the plate.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
