Description

Technical Field

[0001] The present utility model relates to the technical field of battery winding, and particularly relates to a feeding mechanism of a protective battery winding machine. Background Art

[0002] The core winding technology is a process of alternately laminating positive and negative electrode materials and forming a core structure through steps such as winding, electrode forming, liquid injection, and welding. This technology is widely used in various battery power application fields, such as vehicle-mounted batteries, energy storage batteries, and portable electronic devices. In core winding, the positive and negative electrode materials are electrode sheets. When winding the electrode sheets, it is usually necessary to feed them, and a feeding mechanism is required for feeding.

[0003] In the prior art, such as the feeding mechanism of a lithium thionyl chloride battery winding machine disclosed in the publication number: CN218274728U, it includes a base body with a slide rail opened at its upper end, and a battery sheet is inside the slide rail; a limit block plate is arranged inside the slide rail, the limit block plates are symmetrically arranged, and the limit block plate and the first servo motor form a fine adjustment mechanism. The feeding mechanism of this lithium thionyl chloride battery winding machine is provided with a flattening mechanism. By setting a linkage mechanism, the device can drive a roller to rotate to feed the battery sheet, and at the same time can drive a flattening pressing plate to intermittently flatten the upper end of the battery sheet, flattening the concave and convex parts on the surface of the battery sheet. Limit block plates are arranged on both sides of the slide rail, and the distance between the limit block plates can be controlled by a motor, so as to flexibly adjust the distance according to the width of the battery sheet, prevent the slide rail from being too wide, resulting in deviation during feeding, and increase the practicability.

[0004] However, this device still has some problems. Among them, by setting a linkage mechanism, the device can drive a roller to rotate to feed the battery sheet, and at the same time can drive a flattening pressing plate to intermittently flatten the upper end of the battery sheet, flattening the concave and convex parts on the surface of the battery sheet. However, in the actual use process, when the roller rotates to feed the battery sheet, it is continuous, and whenever the flattening pressing plate presses down, it will intermittently squeeze and fix the battery sheet. When the battery sheet is squeezed and fixed, since the roller is still feeding, it will pull the battery sheet, which may cause the battery sheet to be torn or deformed, resulting in a problem of decreased subsequent winding quality. Therefore, we disclose a feeding mechanism of a protective battery winding machine to meet people's needs. Summary of the Utility Model

[0005] The purpose of this application is to provide a feeding mechanism for a protective battery winding machine to solve the problem proposed in the above background technology that when the rotating roller rotates to feed the battery sheet continuously, and whenever the flattening pressing plate presses down, it will intermittently squeeze and fix the battery sheet. When the battery sheet is squeezed and fixed, since the rotating roller is still feeding, it will pull the battery sheet, which may cause the battery sheet to tear or deform, resulting in a decline in the subsequent winding quality.

[0006] To achieve the above purpose, this application provides the following technical solutions: A feeding mechanism for a protective battery winding machine includes a box body.

Flattening rollers are rotatably installed on the two brackets. The two flattening rollers correspond to each other. Two driving motors are fixedly installed on the inner wall of the box body. Driving rollers are fixedly installed at the output ends of the two driving motors. Feeding ports are opened on both sides of the box body.

[0007] Preferably, a first-level bidirectional threaded rod is rotatably installed on the inner bottom wall of the box body. Both of the two adjusting blocks are screwed and installed in the threaded areas on the surface of the first-level bidirectional threaded rod.

A moving groove is opened on the upper side of the placing plate. Two moving blocks are slidably installed in the moving groove. Limiting plates are fixedly installed on the upper sides of the two moving blocks.

[0010] Preferably, a rotating hole is opened on one side of the placing plate. A second-level bidirectional threaded rod is rotatably installed in the rotating hole. Both of the two moving blocks are screwed and installed in the threaded areas on the surface of the second-level bidirectional threaded rod.

[0011] Preferably, two connecting rods are fixedly installed on the inner wall of the box body. Solenoid valves are fixedly installed on one side of each of the two connecting rods. A number of spray holes are opened on one side of the solenoid valve. Nozzles are fixedly installed in the number of spray holes.

[0012] Preferably, a box door is rotatably installed on one side of the box body. Two load-bearing grooves are opened on one side of the box door. The two load-bearing grooves are adapted to the two driving rollers.

[0013] In summary, the technical effects and advantages of this utility model:

When in use, the pole piece can be inserted through one through opening at one end and placed in sequence between the driving roller 11 and the two flattening rollers 7, and then on the other driving roller 11, and then passed out through the through opening on the other side.

[0025] As Figure 3 shown, a first-stage bidirectional threaded rod 9 is rotatably installed on the inner bottom wall of the box body 1. The two adjusting blocks 5 are both screwed and installed in the threaded areas on the surface of the first-stage bidirectional threaded rod 9. The first-stage bidirectional threaded rod 9 is a prior art, and there are two threaded areas with opposite threads on its surface. The two adjusting blocks 5 are respectively screwed and installed on the two opposite threaded areas.

[0026] As Figure 3 shown, an adjusting motor 8 is fixedly installed on the inner bottom wall of the box body 1. The output shaft of the adjusting motor 8 is coaxially installed with the bottom end of the first-stage bidirectional threaded rod 9.

The two adjusting blocks 5 respectively drive the two brackets 6 to approach. The two brackets 6 respectively drive the two flattening rollers 7 to approach each other, so as to squeeze and flatten the upper and lower sides of the pole piece. Then, through the driving rollers 11 installed on both sides of the two flattening rollers 7 and driven by the driving motors 10 respectively to transport it, it can be ensured that the pole piece will not be torn due to extrusion and fixation during the flattening process, improving the feeding effect.

[0028] Embodiment 2 is a further optimization based on Embodiment 1:

Nozzles 19 are fixedly installed in the plurality of spray holes. Two external connection holes 20 are formed on one side of the box body 1. The two electromagnetic valves 18 are both installed on the upper sides of the two placing plates 13. Before use, cleaning gas can be introduced through the two external connection holes 20 and the nozzles 19 can be opened or closed by controlling the electromagnetic valve 18, which is convenient for cleaning the pole piece.
