Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and in particular to an online automatic adjustment device for the gap between pressure rollers in continuous casting and rolling coating. Background Technology

[0002] Currently, in the battery plate manufacturing process, advanced continuous casting and rolling equipment is used to produce continuously cast and rolled plates. After coating, the plates need to be rolled again by flat rollers or patterned rollers to correct the flatness of the plates. The pressure at both ends of the pressure rollers on the production line is achieved by using spring devices. The pressure is adjusted manually by adjusting the nuts, i.e., adjusting the pressure of the springs, in order to adjust the gap between the flat roller and the pressure roller, and between the patterned roller and the pressure roller.

[0003] The existing technology CN201620351297.0 describes a pressure roller machine, which includes a driving roller and a driven roller that roll with a clearance fit, and an adjusting device for adjusting the clearance between the driving roller and the driven roller. The adjusting device includes bearing assemblies located at both ends of the driven roller, an adjusting rod connected to the bearing assemblies, a pressure sensor, and a pressure controller. This structure uses the adjusting rod to correct the pressure value of the pressure controller, ensuring the consistency of pressure at both ends of the pressure roller, thereby ensuring the consistency of flatness after the electrode plate is rolled and corrected.

[0004] However, during the process of the electrode plate passing through the flat roller and the patterned roller, the gap between the pressure rollers cannot be adjusted online. Furthermore, since the flat roller and the patterned roller need to be adjusted to different gaps, the electrode plate is first subjected to the rolling pressure of the flat roller when it passes through. When the gap between the flat rollers is the smallest, it is easy to cause pressure rolling on the electrode plate. The electrode plate after passing through is prone to warping at the edges, which affects the overall rolling effect. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide an online automatic adjustment device for the gap between pressure rollers in continuous casting and rolling coating, so as to solve the problems of the inability to adjust the gap between pressure rollers online and the easy pressure rolling of the electrode plate when the gap between the flat rollers is the smallest, which makes the electrode plate prone to edge warping after passing through.

[0006] To achieve the above objectives, the present invention provides an online automatic adjustment device for the gap between pressure rollers in continuous casting and rolling coating, comprising: a base and a frame mounted on the base; a flat platform for the passage of electrode plates is fixedly mounted on the top of the base, a top platform is provided above the flat platform, the ends of the flat platform and the top platform are fixedly mounted by a support plate, a driving component is provided on one side of the support plate, an anti-tilting component is provided between the flat platform and the top platform, pressure rollers are rotatably mounted on both sides inside the flat platform, and flat rollers and patterned rollers are correspondingly provided on the left and right sides of the top platform and at the top of the pressure rollers, and an adjusting component is provided on the top of the flat rollers and patterned rollers;

[0007] The drive unit rotates the pressure roller, flat roller, and patterned roller. The electrode plate passes between the flat platform and the top platform. The adjustment unit adjusts the gap between the flat roller, patterned roller, and pressure roller respectively. When the gap between the patterned roller and the pressure roller reaches the minimum and the gap between the flat roller and the pressure roller reaches the maximum, the anti-warping unit rolls the electrode plate passing between the flat roller and the patterned roller.

[0008] Preferably, the adjusting component includes an inner slide and an outer slide that are slidably mounted on both sides of the top platform. An inner rod is fixedly mounted on the top of the inner slide, and an outer rod is mounted on the top of the outer slide. The inner and outer rods extend through one side of the top platform and into its interior. A first electric push rod and a second electric push rod are provided inside the top platform. The output end of the first electric push rod is connected to the outer rod, and the output end of the second electric push rod is connected to the inner rod. A first switch and a second switch are provided on one side of the base. The first switch is electrically connected to the first electric push rod, and the second switch is electrically connected to the second electric push rod.

[0009] Preferably, the flower roller and the flat roller are rotatably installed inside the inner slide and the outer slide, respectively. The inner slide and the outer slide are arranged in a mirror symmetrical manner with respect to the center of the top platform. A groove adapted to the inner slide is provided on one side of the frame.

[0010] Preferably, the anti-tilting component includes a straight hole opened inside the top platform, a rotating shaft movable inside the straight hole, a lever installed outside the rotating shaft, two sets of touch switches respectively arranged inside the top platform at both ends of the lever, a receiving cavity opened at the bottom of the top platform, a connecting rod slidably installed inside the receiving cavity, an electromagnet arranged inside the receiving cavity, the electromagnet being electrically connected to the two sets of touch switches, a magnetic block corresponding to the electromagnet being arranged at the top of the cavity inside the connecting rod, and a roller being arranged at the bottom of the connecting rod.

[0011] Preferably, the magnetic poles of the end magnetic field of the electromagnet are the same as the magnetic poles of the magnetic block, and a return spring is connected to the top of the connecting rod.

[0012] Preferably, the two sets of touch switches are respectively arranged at an angle, and the rollers are irregularly distributed.

[0013] Preferably, the driving component includes a servo motor mounted on one side of the support plate. The output end of the servo motor is connected to a transmission rod. A gear column is fixedly mounted on the top end of the transmission rod. An external gear ring meshes with one side of the transmission rod, and an internal gear ring meshes with the other side of the transmission rod. The external gear ring is connected to the end of the pressure roller, and the internal gear ring is connected to the end of the flat roller. The top ends of adjacent pressure rollers are connected by a first synchronous belt, and the top ends of the flat roller and the patterned roller are connected by a second synchronous belt.

[0014] Preferably, the diameters of the inner gear ring and the outer gear ring are matched, and the support plate has sliding holes adapted to the flat roller inside.

[0015] Preferably, the frame has a through groove inside, one end of which is rounded, and a bracket is installed on the top of the frame, with multiple sets of winding rollers distributed inside the bracket.

[0016] Preferably, the gap between the through groove and the flat platform and the top platform forms an electrode channel.

[0017] The beneficial effects of the present invention are as follows: the coated electrode plate is placed between the flat platform and the top platform, and the driving component simultaneously drives the pressure roller, the flat roller and the patterned roller to rotate, so that the flat roller and the patterned roller can roll with the pressure roller. When the gap needs to be adjusted, the distance between the flat roller and the pressure roller and the gap between the patterned roller and the pressure roller are adjusted by the adjusting component, so that the coated electrode plate maintains flatness after rolling.

[0018] When the gap between the patterned roller and the pressure roller reaches its maximum, and the gap between the flat roller and the pressure roller reaches its minimum, the anti-warping component inside the top platform presses down on the electrode plate passing through the flat roller to prevent excessive pressure from causing the electrode plate to warp and to improve the rolling effect of the electrode plate.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0027] The first aspect of the invention, as Figures 1-5 As shown, an online automatic adjustment device for the gap between pressure rollers in continuous casting and rolling coating includes: a base 1 and a frame 2 mounted on the base 1; a flat platform 3 for the passage of electrode plates is fixedly installed on the top of the base 1, a top platform 4 is provided above the flat platform 3, the ends of the flat platform 3 and the top platform 4 are fixedly installed by a support plate 8, a driving component is provided on one side of the support plate 8, an anti-tilting component is provided between the flat platform 3 and the top platform 4, pressure rollers 5 are rotatably installed on both sides inside the flat platform 3, and flat rollers 6 and patterned rollers 7 are provided on the left and right sides of the top platform 4 and correspondingly at the top of the pressure rollers 5, and adjusting components are provided on the top of the flat rollers 6 and patterned rollers 7;

[0028] The drive unit rotates the pressure roller 5, the flat roller 6, and the patterned roller 7. The electrode plate passes between the flat platform 3 and the top platform 4. The adjustment unit adjusts the gap between the flat roller 6, the patterned roller 7, and the pressure roller 5 respectively. When the gap between the patterned roller 7 and the pressure roller 5 reaches the minimum, and the gap between the flat roller 6 and the pressure roller 5 reaches the maximum, the anti-warping unit rolls the electrode plate passing between the flat roller 6 and the patterned roller 7.

[0029] In this embodiment, the coated electrode plate is placed between the flat platform 3 and the top platform 4. The driving component simultaneously drives the pressure roller 5, the flat roller 6, and the patterned roller 7 to rotate, so that the flat roller 6 and the patterned roller 7 can roll against the pressure roller 5. When the gap needs to be adjusted, the distance between the flat roller 6 and the pressure roller 5, as well as the gap between the patterned roller 7 and the pressure roller 5, are adjusted by the adjusting component. After the coated electrode plate has been rolled, when the gap between the patterned roller 7 and the pressure roller 5 reaches its minimum and the gap between the flat roller 6 and the pressure roller 5 reaches its maximum, the anti-warping component inside the top platform 4 presses against the electrode plate that has passed through the flat roller 6 to prevent excessive pressure from causing the electrode plate to warp and to improve the rolling effect of the electrode plate.

[0030] As one implementation method, such as Figure 1 , Figure 4 and Figure 5 As shown, an online automatic adjustment device for the gap between pressure rollers in continuous casting and rolling coating is disclosed. The adjustment components include an inner slide 71 and an outer slide 72 slidably mounted on both sides of a top platform 4. An inner rod 73 is fixedly mounted on the top of the inner slide 71, and an outer rod 74 is mounted on the top of the outer slide 72. The inner rod 73 and the outer rod 74 extend through one side of the top platform 4 and into the interior of the top platform 4. A first electric push rod 75 and a second electric push rod 76 are provided inside the top platform 4. The output end of the first electric push rod 75 is connected to the outer rod 74, and the output end of the second electric push rod 76 is connected to the inner rod 73. A first switch 77 and a second switch 78 are provided on one side of the base 1. The first switch 77 is electrically connected to the first electric push rod 75, and the second switch 78 is electrically connected to the second electric push rod 76.

[0031] Preferably, the flower roller 7 and the flat roller 6 are rotatably installed inside the inner slide 71 and the outer slide 72, respectively. The inner slide 71 and the outer slide 72 are arranged in a mirror symmetrical manner with reference to the center of the top platform 4. A slide groove adapted to the inner slide 71 is opened on one side of the frame 2.

[0032] In this embodiment, when it is necessary to adjust the gap between the flat roller 6 and the pressure roller 5, the first switch 77 is activated, and the first electric push rod 75 drives the outer slide block 72 at the end of the outer rod 74 to move, changing the gap between the flat roller 6 and the pressure roller 5 in the outer slide block 72. When adjusting the gap between the patterned roller 7 and the pressure roller 5, the second switch 78 is activated, and the second electric push rod 76 drives the inner rod 73 to move, causing the inner slide block 71 at the end of the inner rod 73 to move, thus changing the gap between the patterned roller 7 and the pressure roller 5 in the inner slide block 71.

[0033] As one implementation method, such as Figure 1 , Figure 4 and Figure 5 As shown, an online automatic adjustment device for the gap between pressure rollers in continuous casting and rolling coating includes an anti-warping component comprising a straight hole 41 opened inside a top platform 4, a rotating shaft 42 movable inside the straight hole 41, a lever 43 mounted outside the rotating shaft 42, two sets of touch switches 44 respectively provided inside the top platform 4 at both ends of the lever 43, a receiving cavity 45 opened at the bottom of the top platform 4, a connecting rod 46 slidably installed inside the receiving cavity 45, an electromagnet 47 provided inside the receiving cavity 45, the electromagnet 47 being electrically connected to the two sets of touch switches 44, a magnetic block 48 corresponding to the electromagnet 47 being provided at the top of the cavity inside the connecting rod 46, and a roller 49 being provided at the bottom of the connecting rod 46.

[0034] Preferably, the magnetic poles of the end magnetic field of the electromagnet 47 are the same as the magnetic poles of the magnetic block 48, and a return spring is connected to the top of the connecting rod 46.

[0035] Preferably, the two sets of touch switches 44 are respectively set to tilt correspondingly, and the rollers 49 are irregularly distributed.

[0036] In this embodiment, when the gap between the flat roller 6 and the pressure roller 5 reaches its maximum, and the gap between the patterned roller 7 and the pressure roller 5 reaches its minimum, the paddle 43 is tilted under the lifting of the inner rod 73 and the outer rod 74. At this time, the top of the paddle 43 contacts a set of touch switches 44, and the bottom of the paddle 43 contacts another set of touch switches 44, so that the electromagnet 47 generates magnetic force to push the connecting rod 46 after current is passed through it. The connecting rod 46 contacts the passing electrode plate at the bottom of the top platform 4.

[0037] When the flat roller 6 and the patterned roller 7 move downward or upward at the same time, the outer rod 74 and the inner rod 73 simultaneously drive the rotating shaft 42 and the paddle 43 to move inside the straight hole 41. When moving upward or downward, they contact a set of touch switches 44, preventing the electromagnet 47 from being turned on. If the patterned roller 7 in the inner slide 71 moves downward, it drives the inner rod 73 downward, preventing the touch switch 44 from being contacted.

[0038] As one implementation method, such as Figure 1 , Figure 2 and Figure 3 As shown, an online automatic adjustment device for the gap between pressure rollers in continuous casting and rolling coating includes a driving component comprising a servo motor 81 mounted on one side of a support plate 8. The output end of the servo motor 81 is connected to a transmission rod 82. A toothed column 83 is fixedly mounted on the top end of the transmission rod 82. An external toothed ring 84 meshes with one side of the transmission rod 82, and an internal toothed ring 85 meshes with the other side of the transmission rod 82. The external toothed ring 84 is connected to the end of the pressure roller 5, and the internal toothed ring 85 is connected to the end of the flat roller 6. The top ends of adjacent pressure rollers 5 are connected by a first synchronous belt 86, and the top ends of the flat roller 6 and the patterned roller 7 are connected by a second synchronous belt 87. The diameters of the internal toothed ring 85 and the external toothed ring 84 are matched. The support plate 8 has sliding holes inside that are adapted to the flat roller 6.

[0039] In this embodiment, the servo motor 81 starts and drives the transmission rod 82 to rotate. The transmission rod 82 drives the toothed column 83 at the top to rotate synchronously. The toothed column 83 meshes with the outer toothed ring 84 and the inner toothed ring 85 at the same time, thereby driving the corresponding flat roller 6 and pressure roller 5 to rotate and roll. When the gap between the flat roller 6 and the pressure roller 5 is adjusted, the inner toothed ring 85 moves outside the toothed column 83 while rotating, which can maintain rolling while adjusting the gap. At the same time, under the action of the first synchronous belt 86 and the second synchronous belt 87, the patterned roller 7 rotates accordingly when the gap is adjusted.

[0040] In one embodiment, a through groove 9 is provided inside the frame 2. One end of the through groove 9 is rounded. The gap between the through groove 9 and the flat platform 3 and the top platform 4 forms an electrode plate channel. A bracket 10 is installed on the top of the frame 2. Multiple sets of winding rollers 11 are distributed inside the bracket 10.

[0041] In this process, the electrode plate channel is formed by the gap between the through groove 9, the flat platform 3, and the top platform 4. After coating, the electrode plate passes through the electrode plate channel and the winding roller 11 in the support 10, thereby guiding the path of the rolled electrode plate.

[0042] Working principle: The coated electrode plate is placed between the flat platform 3 and the top platform 4. The servo motor 81 starts and drives the transmission rod 82 to rotate. The transmission rod 82 drives the toothed column 83 at the top to rotate synchronously. The toothed column 83 meshes with the outer toothed ring 84 and the inner toothed ring 85, thereby driving the corresponding flat roller 6 and pressure roller 5 to rotate and roll. When it is necessary to adjust the gap between the flat roller 6 and the pressure roller 5, the first switch 77 is activated. The first electric push rod 75 drives the outer slide block 72 at the end of the outer rod 74 to move. The gap between the flat roller 6 and the pressure roller 5 in the outer slide block 72 changes. When adjusting the gap between the patterned roller 7 and the pressure roller 5, the second switch 78 is activated. The second electric push rod 76 drives the inner rod 73 to move. The inner slide block 71 at the end of the inner rod 73 moves, changing the gap between the patterned roller 7 and the pressure roller 5 in the inner slide block 71, thus achieving the purpose of adjusting the gap between the pressure rollers.

[0043] When the gap between the flat roller 6 and the pressure roller 5 is adjusted, the inner gear ring 85 rotates while moving outside the gear column 83, which can maintain rolling pressure while adjusting the gap. When the gap between the flat roller 6 and the pressure roller 5 reaches the minimum, and the gap between the patterned roller 7 and the pressure roller 5 reaches the maximum, the paddle 43 is tilted under the lifting of the inner rod 73 and the outer rod 74. At this time, the top of the paddle 43 contacts a set of touch switches 44, and the bottom of the paddle 43 contacts another set of touch switches 44, so that the electromagnet 47 generates magnetic force to push the connecting rod 46 after current is passed through it. The connecting rod 46 contacts the passing electrode plate at the bottom of the top platform 4, and presses the electrode plate that has passed through the flat roller 6 to avoid excessive pressure causing the electrode plate to warp and improve the rolling effect of the electrode plate.
