Description

Technical Field

[0001] The present invention belongs to the technical field of electrode roll forming equipment, and particularly relates to a roll forming equipment with a cooling structure. Background Art

[0002] The dry electrode is a method for preparing electrodes in the production of lithium-ion batteries. Its main feature is that no solvent is used during the electrode preparation process, and the electrode material is prepared into flakes by drying and pressing. The dry electrode roll pressing equipment is mainly used to compound dry powder electrode active substances with current collectors to form electrode membranes. During the roll pressing process, a large amount of heat is generated. To ensure the forming and processing quality of the dry electrode, the equipment needs to be cooled.

[0003] For example, in a Chinese patent document (CN119502437A), a dry electrode roll pressing equipment with controllable pressure roll gap includes a pressure roll with an inner cavity. There are at least two pressure rolls, and there is a roll pressing gap between the two pressure rolls; a first touch member is arranged in the inner cavity and is separately arranged from the pressure roll. The first touch member has a first touch part, and the first touch part touches the inner wall of the inner cavity. The first touch part and the roll pressing gap are respectively located on the inner and outer sides of the pressure roll wall. Through the above technical solution, the problem in the prior art that the dry powder material is unevenly distributed, resulting in deformation of the pressure roll, reduction of the gap between adjacent pressure rolls, affecting the quality of the formed electrode membrane, and possibly causing uneven thickness, uneven surface, etc. is solved. However, during the use of this equipment, its mechanical energy will be converted into heat energy during roll pressing. If the heat accumulates, it will cause the temperature of the electrode membrane and the pressure roll to rise, and the change of the roll gap caused by the thermal expansion of its material will further affect the forming quality of the electrode membrane. Therefore, improvement is needed. Summary of the Invention

[0004] The purpose of the present invention is to propose a roll forming equipment with a cooling structure to solve the problem in the prior art that during the use process, its mechanical energy will be converted into heat energy during roll pressing. If the heat accumulates, it will cause the temperature of the electrode membrane and the pressure roll to rise, and the change of the roll gap caused by the thermal expansion of its material will further affect the forming quality of the electrode membrane.

[0005] To achieve the above purpose, the present invention adopts the following technical solution: A roll forming equipment with a cooling structure includes a housing. A roll driving unit is arranged on one side of the top of the housing. Two sets of roll units with opposite rotation directions are arranged inside the roll driving unit. A cooling component is arranged inside the roll unit. The cooling component includes a first installation frame, a second installation frame, and a first spiral blade located between the two. An adjustment and adaptation component is arranged inside the first installation frame, and an auxiliary cooling component is arranged inside the second installation frame; The adjusting and adapting component includes a main oil bladder disposed inside the first spiral blade. One side of the main oil bladder is fixedly connected to a second spiral blade. One side of the main oil bladder is communicated with a plurality of auxiliary oil bladders through a pipeline. A plurality of bumps are arranged between the plurality of auxiliary oil bladders. The plurality of bumps are fixedly connected to the same rotating shaft. The liquid inside the auxiliary oil bladder is conveyed into the main oil bladder through the rotating shaft and the bumps to adjust the pitch distance between the second spiral blade and the first spiral blade.

[0006] When the use distance between the plurality of pressure rollers inside the pressure roller unit is adjusted by an external adjusting device, the liquid inside the auxiliary oil bladder is conveyed into the main oil bladder through the pipeline, causing the main oil bladder to expand and drive the second spiral blade to move, so as to adjust the use pitch between the second spiral blade and the first spiral blade, which helps to improve the flow rate of the coolant between the first spiral blade and the second spiral blade, further destroys the coolant laminar flow, and thus effectively improves the overall cooling effect of the equipment. By dynamically adjusting, the equipment is made suitable for the cooling requirements of different thickness electrode membranes in variable working condition production.

[0007] As a further description of the above technical solution: One end of the rotating shaft extends into the first mounting frame and is fixedly connected to a second annular gear. The outer peripheral side of one end of the rotating shaft is rotatably connected inside the first mounting frame through a bearing, and the rotating shaft is arranged as a hollow shaft. One side above the second annular gear is provided with a connecting frame.

[0008] As a further description of the above technical solution: One side of the connecting frame is fixedly connected to the inner wall of the first mounting frame. One side inside the connecting frame is fixedly connected to an auxiliary liquid bladder. One side of the auxiliary liquid bladder is communicated with a main liquid bladder through a pipeline. Springs are arranged on both sides of the auxiliary liquid bladder.

[0009] As a further description of the above technical solution: The side of the auxiliary liquid bladder away from the connecting frame is fixedly connected to a sliding seat. A rack is arranged inside the other side of the sliding seat. One side of the top of the rack is provided with a first electromagnet. One side of the first electromagnet away from the rack is provided with a second electromagnet. The second electromagnet is located inside the sliding seat. The rack is slidably connected inside the connecting frame, and the bottom of the rack meshes with the second annular gear. A connecting spring is arranged on the side of the rack away from the first electromagnet, and the other side of the connecting spring is fixedly connected to the inner wall of the sliding seat. The springs are respectively fixedly connected to the sliding seat and the inner wall of the connecting frame on both sides.

[0010] When the use distance between the plurality of pressure rollers is increased, at this time, the first battery iron and the second electromagnet are powered off, and the limiting mechanism releases the limiting effect on the rotating shaft. The plurality of pressure rollers will stretch the main liquid bladder, and the springs will drive the sliding seat and the rack to move and squeeze the auxiliary liquid bladder, causing the rack to drive the second annular gear to rotate.

[0011] As a further description of the above technical solution: A connecting shaft is rotatably connected to the outer peripheral side of the rotating shaft. The connecting shaft is fixedly connected to the inner peripheral side of the first spiral blade. A plurality of the auxiliary oil sacs are distributed in a circumferential array inside the connecting shaft, and one side of the auxiliary oil sac is fixedly connected to the inner wall of the connecting shaft. A wear-resistant plate is fixedly connected to the side of the auxiliary oil sac away from the inner wall of the connecting shaft. The second spiral blade is slidably sealed inside the first spiral blade.

[0012] As a further description of the above technical solution: The two sets of roll pressing units are symmetrically distributed about the center of the roll pressing drive unit, and a composite gap is provided between the two sets of roll pressing units. A feed port is provided on one side at the top of the roll pressing unit. The feed port is provided on the side away from the center of the housing. Rewinding units are provided on both the upper and lower sides of the roll pressing unit. The rewinding units are located at the center position of the roll pressing drive unit, and one side of the rewinding unit is fixedly connected to the inner wall of the housing.

[0013] As a further description of the above technical solution: The roll pressing unit is composed of a plurality of rollers, and hollow shafts are provided on both sides of the rollers. The outer peripheral side of the hollow shaft is connected to the drive unit inside the roll pressing drive unit through a mounting seat. The use distance between the plurality of rollers inside the roll pressing unit becomes smaller and smaller relative to the feed port. Conveying pipes are communicated on both sides of the roll pressing unit. The main liquid sac is fixedly connected between two adjacent mounting seats.

[0014] When the feed port conveys the material into the roll pressing unit, at this time, the roll pressing unit will convey the electrode film sheet after roll pressing to the composite gap, and after passing through the composite gap, it will be wound inside the rewinding unit. When it is necessary to perform single-sided lamination of the pole piece and the film, the pole piece roll is wound inside the rewinding unit on the other side, so that it is laminated with the electrode film sheet after roll pressing by one side of the roll pressing unit at the composite gap, and then the laminated single-sided electrode is wound on the outer peripheral side of the rewinding unit on the other side. When it is necessary to perform double-sided lamination of the pole piece and the film, the pole piece roll is wound inside the rewinding unit on the other side, so that it is laminated with the electrode film sheets after roll pressing by both sides of the roll pressing unit at the composite gap at the same time. After that, the laminated electrode product is wound on the outer peripheral side of the rewinding unit on the other side or the finished product rewinding unit.

[0015] As a further description of the above technical solution: A hollow conveying rod is connected to the centers inside the first mounting frame and the second mounting frame. The hollow conveying rod is arranged on the inner peripheral side of the rotating shaft, and the hollow conveying rod, the rotating shaft and the connecting shaft are on the same axis. A through hole is formed on one side of the hollow conveying rod facing away from the second mounting frame. One end of the hollow conveying rod away from the second mounting frame extends to the outside of the hollow shaft and is provided with a mounting sleeve. One end of the mounting sleeve away from the hollow conveying rod is communicated with a water outlet, and the water outlet is communicated with the hollow conveying rod. One side at the bottom of the mounting sleeve is communicated with a water inlet, and the water inlet is communicated with the inside of the pressing roller. A limiting through hole is formed on one side inside the second mounting frame, and the limiting through hole is located on one side of the turbine and is arranged in an opposite direction to the through hole inside the hollow conveying rod.

[0016] During the process of driving the pressing roller unit to rotate, the pressing roller driving unit can enable an external liquid supply device to convey coolant to the inside of the pressing roller through the water inlet. At this time, the liquid will be between the inner wall of the hollow conveying rod and the pressing roller, and at this time, the edge on one side of the pressing roller will be cooled. After that, the liquid will be conveyed to the first spiral blade through a pipeline, and the first spiral blade will convert the direct water flow entering the central area inside the pressing roller into a spiral water flow.

[0017] As a further description of the above technical solution: One end of the connecting shaft is rotatably connected inside the second mounting frame. One end of the connecting shaft away from the second mounting frame extends into the first mounting frame and is fixedly connected with a first annular gear. One side at the bottom of the first annular gear is meshed with a gear. A driving motor is arranged inside the gear through a fixed shaft. One side of the driving motor is fixedly connected with the inner wall of the first mounting frame. A limiting mechanism is arranged on one side of the connecting shaft, and the limiting mechanism is sleeved on the outer peripheral side of the rotating shaft.

[0018] The driving motor drives the fixed shaft and the gear to rotate. By using the linkage effect between the gear and the first annular gear, the power is transmitted to the first annular gear, so that the first annular gear drives the connecting shaft, the first spiral blade and the second spiral blade to rotate, so as to make the first spiral blade and the second spiral blade push the liquid to flow, reducing the pressure drop during the use of the cooling system, ensuring the overall operation stability and cooling effect of the cooling system, enabling the equipment to be suitable for the cooling requirements of electrodes with different thicknesses. At this time, the first battery iron and the second electromagnet are electrified and adhered together, and the rotating shaft rotates with the connecting shaft under the action of the limiting mechanism, without affecting the use distance between the first spiral blade and the second spiral blade, so as to ensure the stability of the equipment during use.

[0019] As a further description of the above technical solution: The auxiliary cooling component includes a turbine, which is rotatably connected inside the second mounting frame through a rotating sleeve. An inner cavity is formed on the other side of the second mounting frame, and the turbine is arranged on one side of the through hole. The other end of the rotating sleeve extends into the inner cavity and is fixedly connected with a fan blade. One side of the fan blade is communicated with an air extraction pipe, and the other end of the air extraction pipe passes through the hollow shaft and extends to the outside thereof. A plurality of air outlets are communicated with the outer peripheral side of the inner cavity. The air outlets are located inside the second mounting frame and are arranged on the side opposite to the air extraction pipe.

[0020] The cooled liquid will be transported to the inside of the second mounting frame through the limit through hole, and then transported to the inside of the hollow transport rod through the through hole, and discharged through the hollow transport rod, the mounting sleeve and the water outlet. The flowing liquid will drive the turbine to rotate, so that the rotating sleeve of the turbine drives the fan blade to rotate. The fan blade will be transported to the inside of the pressure roller through the air extraction pipe and the air outlet to cool the edge of the pressure roller on the other side.

[0021] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows: In the present invention, under the comprehensive cooperation of the adjustment and adaptation component, the cooling component and the auxiliary cooling component, the use distance between multiple pressure rollers inside the pressure roller unit is adjusted through an external adjustment device. At this time, the spring will drive the sliding seat and the rack to move, so that the second ring gear drives the rotating shaft and the convex block to rotate, and the liquid inside the auxiliary oil sac is transported to the inside of the main oil sac, causing the main oil sac to expand and drive the second spiral blade to move, so as to adjust the use pitch between the second spiral blade and the first spiral blade, which helps to improve the flow rate of the cooling liquid between the first spiral blade and the second spiral blade, destroys the laminar flow of the cooling liquid, and thus effectively improves the overall cooling effect of the equipment. By dynamically adjusting to make the equipment applicable to the cooling requirements of different thickness electrode membranes in variable working conditions production, while the first spiral blade and the second spiral blade strengthen the heat exchange inside the center of the pressure roller, the equipment uses the drainage power to drive the fan to rotate, realizing the targeted cooling of the edge of the pressure roller, reducing the influence of the cooling water on the other edge of the pressure roller, and further improving the cooling effect of the equipment.

The outer peripheral side of the hollow shaft 5 is connected to the drive unit inside the roller drive unit 2 through a mounting seat. The use distance between multiple rollers inside the roller unit 3 becomes smaller relative to the feed port 4. Conveying pipelines are communicated on both sides of the roller unit 3. The main liquid bladder 812 is fixedly connected between adjacent two mounting seats; Specifically: First, place the device in a suitable position, connect the water inlet 702 to an external liquid supply device, and provide a finished product winding unit on one side of the housing 1 according to actual needs. When the feeding port 4 conveys the material into the pressing roller unit 3, at this time, the pressing roller unit 3 will convey the roll-pressed electrode film to the composite gap, and after passing through the composite gap, it will be wound inside the winding unit 6.
