Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] Example 1

[0047] like Figure 1 to Figure 6 As shown, this embodiment proposes a pole piece dry forming composite device, including:

[0048] Rack 1,

[0049] There are two composite pressing rollers 2, which are rotatably arranged on the frame 1, and there is a composite gap 3 between the two composite pressing rollers 2, and the composite gap 3 is used for passing the material belt;

[0050] A receiving roller 4 is rotatably arranged on the frame 1, and is used for receiving the material strip passing through the composite gap 3 to complete winding;

[0051] There are a plurality of feeding and mounting rollers 5 which are arranged on the frame 1 and are used for mounting material rolls.

[0052] In this embodiment, in order to solve the problem that the dry forming of the electrode in the related technology requires multiple extrusion forming equipment, and there are problems of high overall production cost and low production efficiency, this scheme first extrudes the powder into a material strip, and then completes the winding on the winding roller 4. After the winding is completed, the material roll is installed on the feeding installation roller 5, and then directly introduced into the electrode core, and then the secondary extrusion and composite molding is completed by the composite pressure roller 2. In this way, this scheme can complete the two extrusion processes with only one device, which greatly reduces the production cost. At the same time, due to the reduction in the number of equipment, the transportation process is saved, and the overall work efficiency is also greatly improved, which has extremely high practical value.

[0053] Furthermore, it also includes:

[0054] There are two cutting members 6 rotatably arranged on the frame 1 , and there is a cutting gap 7 between the cutting members 6 . The cutting gap 7 is used for the material strip passing through the composite gap 3 to pass through.

[0055] In this embodiment, in order to ensure the consistency of the electrode width after compounding, this solution is provided with a cutting piece for cutting the motor below the compound gap. The edge of the electrode strip is cut by the cutting piece to ensure the consistency of the overall width, thereby ensuring the product quality and having high practical value.

[0056] Further, the cutting element 6 comprises:

[0057] A mounting seat 8, arranged on the frame 1;

[0058] The cutting shaft 9 is rotatably arranged on the mounting seat 8. Both ends of the cutting shaft 9 are provided with cutting protrusions 10, and the cutting protrusions 10 are used to cut the ends of the material strip.

[0059] In this embodiment, the cutting method in this scheme is to cut by rotating the cutting shaft 9, pass the material strip through the cutting gap 7, and use the cutting protrusions 10 at both ends of the cutting shaft 9 to cut the edge of the material strip, thereby ensuring the consistency of the overall width of the material strip. It is worth noting that the cutting shaft 9 in this scheme can be adjusted and controlled by a separate servo motor to ensure the cutting effect for different models of products.

[0060] Furthermore, the cutting element 6 also includes:

[0061] The adjusting bolt 11 is rotatably arranged on the mounting seat 8. After the adjusting bolt 11 is rotated, the size of the cutting gap 7 is adjusted;

[0062] The elastic member 27 has one end disposed on the adjusting bolt 11 and the other end disposed on the mounting seat 8 . The elastic member 27 is used to prevent the cutting gap 7 from changing suddenly.

[0063] In this embodiment, in order to further ensure the processing of products of different models, the cutting shaft 9 in this solution can adjust the cutting gap 7 by adjusting the bolt 11. At the same time, in order to avoid excessive powder accumulation causing the cutting shaft 9 to jump during the powder pressing process, this solution has an elastic member 27 for adjusting its clamping example, thereby improving the applicability of the overall equipment.

[0064] Furthermore, it also includes:

[0065] There are a plurality of winding rollers 12 rotatably disposed on the frame 1 , and the winding rollers 12 are used to support the material strip.

[0069] The adjusting rod 17 is arranged on the material receiving pressure roller 15 . After the adjusting rod 17 rotates, it cooperates with one of the adjusting holes 14 to adjust the size of the winding gap 16 .

[0070] In this embodiment, in order to control the thickness of the material roll after winding, a winding pressure roller 15 for controlling the thickness of the material roll is provided at the winding roller 4. The specific control process is that when the winding pressure roller 15 is in contact with the material roll as the material roll is wound, the winding pressure roller 15 will rotate. When the adjusting rod 17 is inserted into the adjustment hole 14 at different positions, the size of the winding gap 16 is ensured to control the thickness of the material rolls of different sizes.

[0071] Further, two scraping assemblies 18 are included, and the scraping assemblies 18 include:

[0072] A scraping frame 19 is arranged on the frame 1;

[0073] The scraper 20 is hingedly arranged on the scraper frame 19. After the scraper 20 rotates, it abuts against the composite pressing roller 2 to scrape the powder on the composite pressing roller 2;

[0074] The adjusting member 21 is threadedly disposed on the scraping frame 19 , and the adjusting member 21 abuts against the scraper 20 . After the adjusting member 21 is rotated, it is used to adjust the rotation angle of the scraper 20 .

[0075] In this embodiment, in order to avoid excessive powder sticking to the composite pressure roller 2 when extruding the coating on the material strip, resulting in poor subsequent composite extrusion effect, the present solution also has a scraper 20 for scraping off the powder on the composite pressure roller 2. At the same time, in order to ensure the overall scraping effect, the present solution has an adjustment part 21 for adjusting the abutment force of the scraper 20. By rotating the adjustment part 21, the abutment force of the scraper 20 on the composite pressure roller 2 can be adjusted, so that the practicality of the present solution is further improved.

[0076] Further, the scraping assembly 18 also includes:

[0079] A tension sensor 24 is provided on the frame 1, and the tension sensor 24 abuts against the material strip to detect the winding tension of the material strip;

[0080] The controller 25 is disposed on the receiving roller 4 and is used to receive the winding tension and control the rotation speed of the receiving roller 4 .

[0081] Furthermore, it also includes:

[0082] The receiving guide plate 26 is hingedly arranged on the frame 1 and is located below the cutting gap 7 , and is used for guiding the material strip to the winding roller 12 .

[0083] In this embodiment, in order to ensure that the material strip can be received by the winding tube and then guided to the receiving roller 4 to complete the winding operation after being cut by the cutting shaft 9, this scheme provides a receiving guide plate 26 for guiding the material strip below the cutting gap 7. In this way, the overall receiving efficiency is further improved, which has a higher practical value.
