Description

Technical Field

[0001] This utility model relates to the field of coating die heads, and in particular to a single-layer extrusion coating die head. Background Technology

[0002] In modern industrial production, coating technology is widely used in many fields such as electronics, packaging, and building materials. Single-layer extrusion coating, as a common coating method, plays a key role in the manufacturing process of various products, such as the coating of battery electrodes and the surface treatment of paper. Its coating quality directly affects the performance and quality of the final product. In the processing of industrial products, it is often necessary to apply a layer of coating evenly and smoothly onto a substrate. This is where coating processes are used. Among these processes, extrusion coating, which involves melting the coating into a slurry and applying it to the substrate, is well-suited for coating relatively soft substrates. During extrusion coating, the slurry is evenly and smoothly extruded from the die onto the substrate. In this process, the coating die directly determines the coating effect and important parameters such as the thickness, areal density, and size of the electrode. The consistency of these parameters directly determines the lifespan and performance of the power lithium battery.

[0003] During the coating process, the slurry is added to the cavity of the storage die head. The slurry at the bottom layer will deposit before being coated, which will affect the density distribution of the slurry. Long-term coating will cause changes in viscosity. In addition, the orifice diameter of each die head is fixed, so it is necessary to replace the die head with a different orifice diameter to adapt to the coating requirements of different thicknesses. In view of this technical problem, this application proposes a single-layer extrusion coating die head. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a single-layer extrusion coating die. A motor drives a second sprocket to rotate, which in turn drives a first sprocket via a chain. This first sprocket, in turn, rotates a rotating rod and a stirring plate, thus agitating the slurry within the cavity. This prevents slurry sedimentation, ensuring uniformity and fluidity, and allowing for smoother extrusion from the outlet, thereby improving product quality and stability. By tightening a bolt, an adjusting plate can be raised, changing the outlet diameter to achieve different slurry thicknesses. The adjustment method is simple and easy, requiring no complex operations or tools, meeting the slurry extrusion volume requirements of different product manufacturing processes, and improving the practicality and applicability of the device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A single-layer extrusion coating die head includes an upper die head body, a lower die head body located at the bottom of the upper die head body, a cavity formed at the top rear end of the lower die head body, a rotating rod disposed within the cavity, a stirring plate fixedly connected to the outer wall of the rotating rod, a transmission assembly disposed at the left end of the rotating rod, a rotating block disposed at the top front end of the lower die head body, an adjusting plate fixedly connected to the outer wall of the rotating block, a bolt disposed at the bottom of the adjusting plate, and the bolt being threadedly connected to the lower die head body.

[0007] Furthermore, the transmission assembly includes a sprocket one fixedly connected to the left end of the rotating rod, and a sprocket two is connected to the outer wall of the sprocket one via a chain.

[0008] Furthermore, a motor is provided at the right end of the second sprocket, the non-driving end of the motor is connected to the lower die head body, and the driving end of the motor is fixedly connected to the second sprocket.

[0009] Furthermore, a fixed rod is rotatably connected to the middle of the rotating block, and the fixed rod is fixedly connected to the lower die head body.

[0010] Furthermore, the rear end of the lower die head body is provided with a feed port, which is connected to the cavity.

[0011] Furthermore, a gasket is provided on the adjacent side of the upper die head body and the lower die head body.

[0012] Furthermore, the tip of the bolt penetrates the lower die head body.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the motor drives the second sprocket to rotate, and the second sprocket can drive the first sprocket to rotate through the chain, thereby causing the first sprocket to rotate with the rotating rod and the stirring plate to stir the slurry in the cavity, avoid the slurry from settling in the cavity, ensure the uniformity and fluidity of the slurry, and make the slurry be extruded more smoothly from the discharge port, thereby improving the quality and stability of product production.

[0015] 2. In this utility model, the adjusting plate can be lifted by turning the bolt, thereby changing the diameter of the discharge port to achieve the application of slurry of different thicknesses. The adjustment method is simple and easy to implement, without complicated operation and tools, which meets the requirements of different product production for slurry extrusion volume and improves the practicality and applicability of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-3 This utility model provides an embodiment of a single-layer extrusion coating die head, including an upper die head body 1, a lower die head body 2 at the bottom of the upper die head body 1, and a cavity 8 at the top rear end of the lower die head body 2 for storing slurry. A rotating rod 10 is disposed inside the cavity 8, and a stirring plate 13 is fixedly connected to the outer wall of the rotating rod 10. By rotating the rotating rod 10, the stirring plate 13 on its outer wall can be rotated, thereby stirring the slurry in the cavity 8 and preventing slurry sedimentation. A sprocket 9 is fixedly connected to the left end of the rotating rod 10, and the outer wall of the sprocket 9 is connected by a chain. A second sprocket 11 is connected. When the second sprocket 11 rotates, it can drive the first sprocket 9 to rotate via the chain, which in turn causes the first sprocket 9 to rotate the rotating rod 10. A rotating block 3 is provided at the top front end of the lower die head body 2. An adjusting plate 5 is fixedly connected to the outer wall of the rotating block 3. A bolt 4 is provided at the bottom of the adjusting plate 5. When the bolt 4 is turned upward, the bolt 4 can lift the adjusting plate 5. When the bolt 4 is turned downward, the bolt 4 can lower the adjusting plate 5. The bolt 4 is threadedly connected to the lower die head body 2. The front ends of the lower die head body 2 and the upper die head body 1 are the discharge ports.

[0023] Reference Figure 1-3The upper die head 11 has a motor 12 at its right end. The non-driving end of the motor 12 is connected to the lower die head body 2, and the driving end of the motor 12 is fixedly connected to the upper die head 11. The motor 12 can drive the upper die head 11 to rotate. A fixed rod 14 is rotatably connected to the middle of the rotating block 3. The rotating block 3 can rotate on the outer wall of the fixed rod 14, thereby allowing the adjusting plate 5 to rotate. The fixed rod 14 is fixedly connected to the lower die head body 2. A feed port 7 is provided at the rear end of the lower die head body 2. The feed port 7 communicates with the cavity 8, and the slurry enters the cavity 8 through the feed port 7. A gasket 6 is provided on the adjacent side of the upper die head body 1 and the lower die head body 2. The top of the bolt 4 penetrates the lower die head body 2.

[0024] Working principle: First, the slurry enters the cavity 8 through the feed port 7, and then is extruded through the front end of the upper die head body 1 and the lower die head body 2. The motor 12 drives the sprocket 11 to rotate. The sprocket 11 drives the sprocket 9 to rotate through the chain. The sprocket 9 drives the rotating rod 10 to rotate. By rotating the rotating rod 10, the stirring plate 13 on its outer wall can be rotated, thereby stirring the slurry in the cavity 8 to prevent slurry sedimentation. When it is necessary to adjust the diameter of the discharge port, the adjusting plate 5 can be lifted upward by turning the bolt 4, thereby causing the rotating block 3 to rotate, thereby reducing the distance between the adjusting plate 5 and the bottom of the upper die head body 1 to adjust the diameter of the discharge port.
