Description

Technical Field

[0001] This utility model relates to the field of battery processing auxiliary equipment, and in particular to an electrode coating die slurry recovery device. Background Technology

[0002] Appendix Figure 1 The structure shown is that of the current positive electrode, with tabs (101) at both ends and a main material coating layer (103) in the middle. Between the main material coating layer and the tabs is a side coating layer (102). After the side coating layer and the main material coating layer are coated, some coating will slide off. In order to recover the sliding coating, the device shown in patent publication document CN221208775U is usually used to recover the coating. However, since the coating used in the adhesive layer and the main material coating layer are different, the device shown in CN221208775U will cause the two coatings to mix completely during the sliding process. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes an electrode coating die slurry recovery device. By combining a base plate and a diversion trough plate, the coating material flowing down the electrode is diverted through the diversion trough plate, thereby achieving the recovery and reuse of a portion of the flowing coating material.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A slurry recovery device for electrode coating die heads includes a base plate, a first hopper, a second hopper, a third hopper, and a diversion trough plate. The first, second, and third hoppers are all disposed at one end of the base plate, and the first and third hoppers are respectively located at both ends of the second hopper, and both the first and third hoppers are connected to the second hopper. The diversion trough plate is disposed on the base plate, and there are two diversion trough plates. The outlet of one diversion trough plate is connected to the first and second hoppers, and the outlet of the other diversion trough plate is connected to the second and third hoppers. Each diversion trough plate contains several diversion plates, and the diversion plates in each diversion trough plate are parallel and do not contact each other.

[0006] The method of using this type of die head slurry recovery device is as follows: First, fix the base plate below the positive electrode sheet, with one end of the base plate close to the positive electrode sheet. The positive electrode sheet is above the base plate, and the first, second, and third hoppers are below the base plate. The coatings on the edge adhesive layer (denoted as coating A) and the main material coating layer (denoted as coating B) on the positive electrode sheet will flow at the base plate. At the beginning of the downward flow, coating A and coating B flow downward together. A diversion trough plate is set below the junction of the edge adhesive layer and the main material coating layer. The diversion trough plate will divide the remaining coatings. The two diversion trough plates divide the coatings into three sections: left, middle, and right. The left section, coating A+B, flows into the first hopper, the middle section, coating B, flows into the second hopper, and the right section, coating B+A, flows into the third hopper. In this way, coating B is recovered. The coatings in the first and third hoppers, which are A+B, cannot be directly reused because they are a mixture. They need to be separated before reuse or directly discarded.

[0007] Similarly, in this device, parallel and non-contact guide plates are set inside the diversion channel plate. The guide plates can divert the paint, thereby ensuring that the paint flows down with a more obvious boundary.

[0008] Specifically, to facilitate the collection of paint, collection buckets are installed below the first, second, and third hoppers.

[0009] In summary, by combining the base plate and the diversion trough plate, the coating that slides down the electrode sheet is diverted through the diversion trough plate, thereby achieving the recycling of part of the sliding coating.

[0010] Optionally, the base plate is provided with a clamping buckle, and the diversion channel plate is provided with a locking plate, the locking plate engaging with the clamping buckle.

[0011] The diversion channel plate engages with the clamping buckle on the base plate via its own locking plate. Since the diversion channel plate and the locking plate are engaged together, different specifications of diversion channel plates can be replaced as needed to divert the coating flowing down from the electrode sheets of different specifications.

[0012] Optionally, it also includes a flow guide, which is an arc-shaped flow guide, with one end of the flow guide abutting the flow divider plate and the other end of the flow guide abutting the base plate.

[0013] The function of the flow guide is twofold: to guide the flow and to serve the purpose of clamping the plate and holding buckle. In use, one end of the flow guide is attached to the flow distribution plate, and the other end of the flow guide is attached to the electrode plate.

[0014] Optionally, the base plate is provided with mounting holes.

[0015] Optionally, there are multiple mounting holes, and the mounting holes are circular.

[0016] The base plate is installed onto the corresponding equipment through the mounting holes.

[0017] Optionally, the diversion plate is provided at the junction of the first hopper and the second hopper, and at the junction of the second hopper and the third hopper.

[0018] The flow divider is provided at the junction of the second hopper and the third hopper. The flow divider ensures that the separated paint will not mix again when it finally enters the hopper.

[0019] Optionally, the diverter plate is perpendicular to the base plate.

[0020] Optionally, the distance between two adjacent flow dividers on the same flow divider plate is equal.

[0021] The beneficial effects of this utility model are: by combining the base plate and the diversion groove plate, the coating that slides down on the electrode sheet is diverted through the diversion groove plate, thereby realizing the recycling of part of the sliding coating.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0029] As attached Figure 2 As shown, an electrode coating die slurry recovery device includes a base plate 2, a first hopper 501, a second hopper 502, a third hopper 503, and a diversion trough plate 3. The first hopper 501, the second hopper 502, and the third hopper 503 are all located at one end of the base plate 2. The first hopper 501 and the third hopper 503 are located at both ends of the second hopper 502, and the first hopper 501 and the third hopper 503 are connected to the second hopper 502. The diversion trough plate 3 is located on the base plate 2. There are two diversion trough plates 3. The outlet of one diversion trough plate 3 is connected to the first hopper 501 and the second hopper 502, and the outlet of the other diversion trough plate 3 is connected to the second hopper 502 and the third hopper 503. Each diversion trough plate 3 contains several diversion plates 4, and the diversion plates 4 in each diversion trough plate 3 are parallel and do not contact each other.

[0030] The method of using this type of die head slurry recovery device is as follows: First, fix the base plate 2 to the positive electrode plate (structure as shown in the attached figure). Figure 1Below the bottom plate 2 (as shown), one end of the bottom plate 2 is attached to the positive electrode sheet. The positive electrode sheet is above the bottom plate 2, and the first hopper 501, the second hopper 502, and the third hopper 503 are below the bottom plate 2. The coatings on the edge coating layer 102 (denoted as coating A) and the main material coating layer 103 (denoted as coating B) on the positive electrode sheet flow to the bottom plate 2. When they first start flowing downwards, coating A and coating B flow downwards together. A flow divider plate 3 is provided below the junction of the edge coating layer 102 and the main material coating layer 103. Plate 3 will divide the remaining paint into three sections: left, middle, and right. The left section, paint A+B, flows into the first hopper 501; the middle section, paint B, flows into the second hopper 502; and the right section, paint B+A, flows into the third hopper 503. This achieves the recycling of paint B. The paint A+B in the first hopper 501 and the third hopper 503 is a mixture and cannot be directly reused. It needs to be separated before reuse or directly discarded.

[0031] Similarly, in this device, parallel and non-contact guide plates are set inside the diversion trough plate 3. The guide plates can divert the paint, thereby ensuring that the paint flows down with a more obvious boundary.

[0032] Specifically, in order to collect the paint, a collection bucket 6 is installed below the first hopper, the second hopper 502, and the third hopper.

[0033] In summary, by combining the base plate 2 and the diversion trough plate 3, the coating that slides down the electrode sheet is diverted through the diversion trough plate 3, thereby realizing the recycling of part of the sliding coating.

[0034] As attached Figure 2 As shown, a clamping buckle 202 is provided on the base plate 2, and a locking plate 301 is provided on the diversion channel plate 3. The locking plate 301 and the clamping buckle 202 are engaged together.

[0035] The diversion trough plate 3 engages with the clamping buckle 202 on the base plate 2 via its own locking plate 301. Since the diversion trough plate 3 and the locking plate 301 are engaged together, different specifications of diversion trough plates 3 can be replaced as needed to divert the coating flowing down from the electrode sheets of different specifications.

[0036] As attached Figure 2 As shown, it also includes a flow guide, which is an arc-shaped flow guide. One end of the flow guide abuts against the flow divider plate 3, and the other end of the flow guide abuts against the bottom plate 2.

[0037] The function of the flow guide is twofold: to guide the flow and to serve the purpose of clamping plate 301 and clamping buckle 202. In use, one end of the flow guide is attached to the flow distribution plate 3, and the other end of the flow guide is attached to the electrode sheet.

[0038] As attached Figure 2 As shown, mounting holes are provided on the base plate 2.

[0039] As attached Figure 2 As shown, there are multiple mounting holes, and the mounting holes are circular.

[0040] The base plate 2 is installed onto the corresponding equipment through the mounting holes.

[0042] A flow divider 4 is provided at the junction of the second hopper 502 and the third hopper 503. The flow divider 4 ensures that the paint that has been separated will not mix again when it finally enters the hopper.

[0043] As attached Figure 2 As shown, the diverter plate 4 is perpendicular to the base plate 2.

[0044] As attached Figure 2 As shown, the distance between two adjacent diversion plates 4 on the same diversion plate 3 is equal.
