[0001] The present invention relates to the technical field of extrusion devices, and in particular to an extrusion device for producing semi-solid lithium battery electrode sheets. Background Art
[0002] Semi-solid lithium battery is a new type of battery technology. It is an improvement on the traditional lithium battery and has some characteristics of liquid lithium battery and all-solid lithium battery. When producing semi-solid lithium battery, an extrusion device is required to extrude the electrode sheet of the semi-solid lithium battery into a suitable thickness.
[0003] In the prior art, there is a patent document with a publication number of CN218656103U, which discloses a lithium battery electrode sheet extrusion molding device, in which a bidirectional screw is rotatably installed at the middle end of the inner side of each hollow frame through a bearing, a rotating rod is fixedly installed on the bottom surface of the bidirectional screw, and a follower gear is fixedly sleeved on the outer surface of the bottom of each rotating rod. The technical solution of the patent document is respectively meshed with the transmission gear and the follower gear through the inner side of the transmission chain, so that when the servo motor is running and the transmission gear is driven to rotate, the rotating rod and the bidirectional screw on both sides can be driven to rotate synchronously and in the same direction, and then in the process of the bidirectional screw rotation transmission, the two sets of adjustment sleeves are driven together with the extrusion rollers between the inner sides thereof to move vertically synchronously, thereby realizing the adjustment of the vertical spacing between the extrusion rollers while reducing the difficulty of its adjustment operation control and the cost of the driving element.
[0004] The above-mentioned and prior arts have the following defects: when using the extrusion molding device, it is necessary to first unfold the rolled electrode sheet, and then pass the electrode sheet through two extrusion rollers. During this process, since the electrode sheet is thin and wide, and the distance between the two extrusion rollers is small, it is easy to cause the electrode sheet to bend during the alignment process, resulting in creases or even damage, which makes the operation extremely inconvenient.
[0005] Therefore, an extrusion device for producing semi-solid lithium battery electrode sheets is proposed. Summary of the invention
[0006] The purpose of the present invention is to solve the disadvantage that it is difficult to pass an electrode sheet through two extrusion rollers, and to propose an extrusion device for producing semi-solid lithium battery electrode sheets.

The extrusion structure includes a fixing rod fixedly mounted on the upper surface of the base, a roller and a pressure roller for extruding the electrode sheet, and a traction rope for linking the roller and the pressure roller. The upper end of the fixing rod is fixedly connected to a support plate;

[0048] The specific arrangement and functions of the limiting structure 6, the extruding structure 7 and the adjusting structure 8 are described in detail below.
[0049] like Figure 2-Figure 5As shown, a clamping hole 606 is provided on the surface of the connecting plate 4, and the clamping rod 601 passes through the clamping hole 606. The bending plate 602 is fixedly connected to the clamping rod 601, and the rotating plate 604 is rotatably connected to the bending plate 602. A rectangular plate 605 is fixedly connected to the surface of the bending plate 602. The arc surface of the clamping rod 601 is sleeved with a first spring 603. The two ends of the first spring 603 are respectively fixedly connected to the bending plate 602 and the fixing clamp 3. When one bending plate 602 is pulled upward, the movement of the bending plate 602 will drive the clamping rod 601 to move. When the clamping rod 601 is pulled out from the inner wall of the clamping hole 606, the fixed roller 5 is moved. The movement of the fixed roller 5 will drive one connecting plate 4 to rotate along the arc surface of the clamping rod 601, and the other connecting plate 4 will rotate along the arc surface of the clamping rod 601. The connecting plate 4 will slide out from the inner wall of the fixing clamp 3, and the fixed roller 5 will move away from the top of the driven roller 11. A clearance groove 607 is provided on the surface of the connecting plate 4. The size of the clearance groove 607 is adapted to the size of the clamping rod 601. The clearance groove 607 is connected to the clamping hole 606. The clamping rod 601 moves and abuts against the inner wall of the clearance groove 607. Continuing to move the connecting plate 4 will make the clamping rod 601 slide from the clearance groove 607 into the clamping hole 606, thereby ensuring that the clamping rod 601 can be quickly inserted into the clamping hole 606 later. A parallel plate 608 is fixedly connected to the surface of the fixing clamp 3, and one end of the parallel plate 608 is fixedly connected to an arc frame 609. The inner wall of the arc frame 609 is slidably connected to an arc The surface of the connecting plate 4 is fixedly connected with a transmission plate 611, and the transmission plate 611 is slidably connected to the arc plate 610. The surface of the parallel plate 608 is slidably connected with a friction block 612, and the friction block 612 is against the surface of the arc plate 610. A second spring 613 is fixedly connected between the friction block 612 and the fixing clamp 3. One end of the arc plate 610 is fixedly connected with a rubber sleeve 614. The position of the arc plate 610 relative to the transmission plate 611 is provided with a protrusion. The connecting plate 4 rotates to contact with the rubber sleeve 614. The rubber sleeve 614 will reduce the collision force between the arc plate 610 and the connecting plate 4, and then the rubber sleeve 614 will drive the arc plate 610 along the arc frame 609. The inner wall slides. At this time, since the friction block 612 is pressed against the surface of the arc plate 610 by the elastic force of the second spring 613, the friction between the friction block 612 and the arc plate 610 will slow down the sliding speed of the arc plate 610, thereby slowing down the moving speed of the fixed roller 5, avoiding the fixed roller 5 from being damaged by violent collision with external objects. The surface of the fixed clamp 3 is fixedly connected with a U-shaped plate 615, and the U-shaped plate 615 is slidably connected to the bending plate 602. When the rotating plate 604 drives the bending plate 602 to slide upward along the surface of the U-shaped plate 615, the U-shaped plate 615 limits the moving path of the bending plate 602, thereby enabling the rotating plate 604 to align with the connecting plate 4.
[0050] like Figure 6-Figure 9As shown, a mounting plate 703 is slidably connected inside the support plate 702, a roller 704 is rotatably connected to the mounting plate 703, a sliding frame 705 is slidably connected to the surface of the support plate 702, a round rod 706 is rotatably connected inside the sliding frame 705, an L-shaped plate 707 is fixedly connected to the arc surface of the round rod 706, the L-shaped plate 707 is rotatably connected to the pressure roller 708, two ends of a traction rope 709 are respectively fixedly connected to the L-shaped plate 707 and the mounting plate 703, the sliding frame 705 and the support plate 702 are both slidably connected to the traction rope 709, a bolt 710 is threadedly connected to the sliding frame 705, and the bolt 710 passes through the sliding frame 705 and rests on the surface of the support plate 702. The arc surface of the round rod 706 is sleeved with a torsion spring 711. The two ends of the torsion spring 711 are fixedly connected to the sliding frame 705 and the round rod 706 respectively. When the electrode sheet is pressed, the electrode sheet will squeeze the roller 704, and the roller 704 will drive the mounting plate 703 to move downward. The movement of the mounting plate 703 will pull the traction rope 709, and the traction rope 709 will drive the L-shaped plate 707 to move, and the L-shaped plate 707 will drive the pressure roller 708 to move. At this time, the roller 704 and the pressure roller 708 can cooperate to limit the position of the electrode sheet to prevent the electrode sheet from being moved due to its own The lower surface of the mounting plate 703 is fixedly connected with a positioning plate 713, and the lower surface of the support plate 702 is fixedly connected with a strip plate 714. A baffle plate 715 is slidably connected inside the strip plate 714. The size of the baffle plate 715 is adapted to the size of the positioning plate 713. A leaf spring 716 is fixedly connected to the surface of the baffle plate 715. One end of the leaf spring 716 is fixedly connected to the strip plate 714. When the mounting plate 703 moves downward, the movement of the mounting plate 703 will drive the movement of the positioning plate 713, and the movement of the positioning plate 713 will squeeze Baffle 715, when baffle 715 slides inside strip plate 714, leaf spring 716 will be stretched. When pressure roller 708 contacts electrode sheet, positioning plate 713 will be aligned with baffle 715. Leaf spring 716 will contract at this moment. Baffle 715 will be inserted into positioning plate 713 with the help of elastic force of leaf spring 716. Baffle 715 can limit the position of positioning plate 713, thereby limiting the position of roller 704. The lower surface of support plate 702 is rotatably connected with steering roller 712. Steering roller 712 is slidably connected with traction rope 709. Steering roller 712 can adjust the moving angle of traction rope 709.
[0051] like Fig. 9 and Fig.10As shown, the inner wall of the threaded tube 81 is threadedly connected with a threaded rod 82, the threaded rod 82 is rotatably connected to the guide ball 83, the guide ball 83 is slidably connected to the traction rope 709, and the arc surface of the threaded rod 82 is fixedly connected with a dial ring 84. When the dial ring 84 is dialed, the threaded rod 82 will drive the guide ball 83 to move downward and tighten the traction rope 709, so that the traction rope 709 can work normally, and the arc surface of the guide ball 83 is fixedly connected with a positioning rod 85, one end of the positioning rod 85 is fixedly connected with a positioning ring 86, and the positioning ring 86 is slidably connected to the threaded tube 81. The outer periphery of the cross section of the threaded tube 81 is a regular hexagon. The movement of the guide ball 83 will drive the positioning rod 85 to move, and the movement of the positioning rod 85 will drive the positioning ring 86 to slide along the surface of the threaded tube 81. At this time, the threaded tube 81 with a regular hexagonal outer periphery in the cross section can limit the moving path of the positioning ring 86, thereby limiting the position of the guide ball 83.
[0052] The overall working principle is that when the electrode sheet of the semi-solid lithium battery is extruded, the rolled electrode sheet is placed on the placement rack 12, and then a bending plate 602 is pulled upward. The movement of the bending plate 602 will drive the clamping rod 601 to move. When the clamping rod 601 is pulled out from the inner wall of the clamping hole 606, the fixed roller 5 is moved. The movement of the fixed roller 5 will drive a connecting plate 4 to rotate along the arc surface of the clamping rod 601, and the other connecting plate 4 will slide out from the inner wall of the fixing clamp 3. At this time, the fixed roller 5 will move away from the top of the driven roller 11. In this process, the transmission plate 611 follows the movement of the rotating connecting plate 4 to drive the arc plate 610 to slide along the inner wall of the arc frame 609. When the arc plate 610 slides a certain distance, it will be out of contact with the transmission plate 611, and the connecting plate 4 continues to rotate. The rubber sleeve 614 will contact with the rubber sleeve 614, and the rubber sleeve 614 will reduce the collision force between the arc plate 610 and the connecting plate 4. Then the rubber sleeve 614 will drive the arc plate 610 to slide along the inner wall of the arc frame 609. At this time, since the friction block 612 is pressed against the surface of the arc plate 610 with the help of the elastic force of the second spring 613, the friction between the friction block 612 and the arc plate 610 will delay the sliding speed of the arc plate 610, thereby delaying the moving speed of the fixed roller 5, and avoiding the fixed roller 5 from being damaged by violent collision with external objects. After that, the electrode sheet is unfolded. At this time, the electrode sheet can be directly placed above the moving roller 11. In this process, there is no need to frequently adjust the electrode sheet to pass through the moving roller 11 and the fixed roller 5, which is convenient for operation. Then, the electrode sheet continues to be moved. The electrode sheet makes the electrode sheet contact with the roller 704, and then presses the electrode sheet, the electrode sheet will squeeze the roller 704, the roller 704 will drive the mounting plate 703 to move downward, the movement of the mounting plate 703 will pull the traction rope 709, the traction rope 709 will slide along the surface of the steering roller 712, the support plate 702 and the sliding frame 705, the steering roller 712 can adjust the movement angle of the traction rope 709, the traction rope 709 will drive the L-shaped plate 707 to move, the L-shaped plate 707 will drive the pressure roller 708 to move, the round rod 706 will follow the L-shaped plate 707 to rotate and twist the torsion spring 711, in the process of the mounting plate 703 moving downward, the movement of the mounting plate 703 will drive the positioning plate 713 to move, the movement of the positioning plate 713 will squeeze the baffle 715, the baffle 715 Sliding along the strip plate 714 will stretch the leaf spring 716. When the pressure roller 708 contacts the electrode sheet, the positioning plate 713 will be aligned with the baffle 715. At this time, the leaf spring 716 contracts, and the baffle 715 will be inserted into the positioning plate 713 with the help of the elastic force of the leaf spring 716. The baffle 715 reaches the position of limiting the positioning plate 713, thereby limiting the position of the roller 704. At this time, the roller 704 and the pressure roller 708 can cooperate to limit the position of the electrode sheet to prevent the electrode sheet from rebounding due to its own elastic force, which affects the subsequent resetting of the fixed roller 5. Then, the connecting plate 4 is moved in the opposite direction. The connecting plate 4 will drive the fixed roller 5 to move. The connecting plate 4 moves and contacts with the rotating plate 604. At this time, the connecting plate 4 will squeeze the rotating plate 604, and the rotating plate 604 will rotate and contact with the rectangular plate 605.At this time, the rectangular plate 605 will prevent the rotating plate 604 from continuing to rotate, so the connecting plate 4 continues to squeeze the rotating plate 604, which will cause the rotating plate 604 to drive the bending plate 602 to slide upward along the surface of the U-shaped plate 615. The U-shaped plate 615 reaches the effect of limiting the moving path of the bending plate 602, so that the rotating plate 604 can be aligned with the connecting plate 4. The movement of the bending plate 602 will lift the clamping rod 601 and stretch the first spring 603. When the connecting plate 4 slides into the fixing clamp 3 and is located under the clamping rod 601, the rotating plate 604 will be out of contact with the connecting plate 4. At this time, the first spring 603 begins to shrink, and the bending plate 602 will use the elastic force of the first spring 603 to drive the clamping rod 601 to move downward. The movement of the clamping rod 601 will abut against the inner wall of the yielding groove 607. Continuing to move the connecting plate 4 will cause the clamping rod 601 to slide from the yielding groove 607 into the clamping hole 60 6, when the clamping rod 601 will continue to slide downward and insert into the clamping hole 606 to limit the position of the connecting plate 4, during this process, the transmission plate 611 will follow the rotating connecting plate 4 to move and contact the arc plate 610, and the transmission plate 611 will slide along the surface of the arc plate 610. When the clamping rod 601 is aligned with the clamping hole 606, the transmission plate 611 will contact the protrusion on the surface of the arc plate 610. At this time, the arc plate 610 will prevent the transmission plate 611 from continuing to move, thereby preventing the connecting plate 4 from continuing to rotate, and further facilitating the insertion of the clamping rod 601 into the clamping hole 606. After that, the connecting plate 10 is driven to move by controlling the electric push rod 9. The movement of the connecting plate 10 will cause the moving roller 11 to squeeze the electrode sheet on the arc surface of the fixed roller 5. When the electrode sheet is pulled by external equipment, the moving roller 11 cooperates with the fixed roller 5 to squeeze the electrode sheet to a suitable thickness.
[0053] When it is necessary to extrude electrode sheets of different widths, the bolt 710 is turned to disengage the bolt 710 from the support plate 702, and then the dial ring 84 is turned. The dial ring 84 drives the threaded rod 82 to rotate, and the threaded rod 82 drives the guide ball 83 to move upward with the help of the thread. At this time, the traction rope 709 is relaxed, and then the sliding frame 705 is moved along the surface of the support plate 702. The round rod 706 moves along with the movement of the sliding frame 705 to drive the L-shaped plate 707 to move. The movement of the L-shaped plate 707 drives the pressure roller 708 to move and pull the traction rope 709. After the distance between the two pressure rollers 708 is adjusted to a suitable position, the pressure roller 708 is rotated. The bolt 710 is rotated in the direction. When the bolt 710 contacts the surface of the support plate 702, the bolt 710 reaches the function of limiting the position of the sliding frame 705. Then, the dial ring 84 is turned in the opposite direction. At this time, the threaded rod 82 will drive the guide ball 83 to move downward and tighten the traction rope 709, so that the traction rope 709 can work normally. The movement of the guide ball 83 will drive the positioning rod 85 to move. The movement of the positioning rod 85 will drive the positioning ring 86 to slide along the surface of the threaded tube 81. At this time, the threaded tube 81 with a regular hexagonal outer periphery in the cross section can limit the moving path of the positioning ring 86, thereby limiting the position of the guide ball 83.
[0054] When it is no longer necessary to extrude the electrode sheet, pull the baffle 715 to disengage the baffle 715 from the positioning plate 713. At this time, the torsion spring 711 begins to twist, and the torsion spring 711 drives the round rod 706 to rotate. The rotation of the round rod 706 causes the L-shaped plate 707 to rotate in the opposite direction and reset. The rotation of the L-shaped plate 707 causes the pressure roller 708 to disengage from the electrode sheet, so that the electrode sheet is no longer extruded, which facilitates the subsequent processing of the electrode sheet. At the same time, the electrode sheet will pull the traction rope 709, and the traction rope 709 will drive the mounting plate 703 to move upward through the steering roller 712. The movement of the mounting plate 703 will reset the roller 704.
