Description

Technical Field

[0001] The present application relates to the technical field of roller presses, and in particular to an adaptive device for correcting roller deformation and deflection. Background Art

[0002] In the production process of lithium batteries, the roller press is one of the indispensable equipment. The main function of the roller press is to compact the lithium battery pole pieces that have been coated and dried to a certain degree to meet the manufacturing process requirements.

[0003] In order to improve production efficiency, battery manufacturers produce pole pieces with wider widths, from the usual 800mm width to the current pole pieces with widths of more than 1500mm. The corresponding width of the roller press also becomes wider. With the same roller diameter, the wider the roller surface, the greater its deflection deformation. The deflection deformation of the roller will cause the compaction thickness of the pole piece to be inconsistent with the requirements. This problem is the key and difficult problem in the roller pressing process.

[0004] The roller presses currently on the market solve the above problems mainly by using hydraulic bending cylinder technology to control the roller deflection and deformation of the roller press during wide-width rolling. However, the upper roller bearing seats of most manufacturers are directly hard-connected to the top of the arch, resulting in a situation where a large bending cylinder force is required but the roller deflection and deformation are not obvious. Utility Model Content

[0005] Based on this, it is necessary to provide a roll deformation deflection correction adaptive device, including an arch assembly, a roll assembly, a bending cylinder assembly, a hydraulic system, and an arc pad assembly. The arch assembly includes an arch frame in the shape of a "mouth"; the roll assembly includes an upper roll assembly and a lower roll assembly, and the upper roll assembly and the lower roll assembly are arranged in the arch assembly with an upper and lower interval, and the two ends of the upper roll assembly and the lower roll assembly are respectively connected to the arch frame; the two ends of the upper roll assembly and the lower roll assembly are respectively positioned with the arch frame through the bending cylinder assembly;

[0006] The hydraulic system is installed on the arch assembly and is located directly below the lower roller assembly; the arc pad assembly includes an upper arc pad and a lower arc pad, the upper arc pad is installed on the upper inner wall of the arch frame, and the lower arc pad is installed on the upper roller assembly, and the upper arc pad and the lower arc pad are arranged vertically opposite each other.

[0007] The upper arc pad and the lower arc pad both include a support pad pressing block and a docking portion. The support pad pressing block is provided with a screw hole. The support pad pressing block is installed on the mounting surface or the upper roller assembly through threads.

[0008] One side of the docking portion is fixed to the support pad pressing block, and the other side is in an arc shape; the other sides of the two docking portions correspond to each other.

[0009] The upper arc pad and the lower arc pad are respectively provided with a countersunk hole and a threaded hole for positioning, and the countersunk hole and the threaded hole are communicated.

[0010] A limiting screw is connected between the arch frame and the upper roller assembly, and the limiting screw is arranged on one side of the arc pad assembly close to the end of the upper roller assembly.

[0011] The two ends of the upper roller assembly and the lower roller assembly are respectively installed on the arch frame through bearing seats, the lower arc pad is fixed on the bearing seat of the upper roller assembly, and the lower arc pads are installed on the bearing seats at both ends of the upper roller assembly, and the upper arc pad is provided directly above the lower arc pad.

[0012] The arc pad assembly is located directly above the hydraulic system.

[0013] Both ends of the upper roller assembly and both ends of the lower roller assembly are provided with bent cylinder seats for connecting the bent cylinder assembly. The archway frame is provided with multiple fixed seats for connecting the bent cylinder assembly. The multiple bent cylinder seats correspond to the multiple fixed seats one by one, and the two ends of the bent cylinder assembly are respectively connected to the corresponding bent cylinder seats and fixed seats.

[0014] Compared with the prior art, the advantages of the utility model are:

[0015] The utility model provides a roller deformation deflection correction adaptive device. When the roller deformation deflection correction adaptive device is working, when the upward force of the hydraulic system causes the lower roller assembly to deform upward, a reaction force is applied to the roller assembly through the bending cylinder assembly. Since the upper roller assembly and the arch frame are not connected in the original hard connection mode, but are connected through an arc pad assembly, the upper roller assembly has space for upward deformation, thereby increasing the torque of the bending cylinder force. Specifically, when the upper roller assembly is subjected to force, it can adaptively deform according to the size and direction of the external force, thereby reducing the impact force and vibration force on the mechanical structure or equipment, which is beneficial to improving the stability and reliability of the equipment, and also enables it to be suitable for the needs under different working conditions, and realizes the effect of large deformation of the roller with small bending cylinder force; and the arc pad assembly adopted in the present application has good stress distribution characteristics, which can reduce the stress concentration degree of the roller assembly and the material, reduce material stress and deformation, and is beneficial to extending the service life of parts.

[0030] A self - adaptive device for correcting the deformation deflection of a roll includes a housing component, a roll component, a bending cylinder component 4, a hydraulic system 9, and an arc - shaped pad component 8. The roll component includes an upper roll component 2 and a lower roll component 3. The housing component includes a housing frame 1 in the shape of a "mouth". The upper roll component 2 and the lower roll component 3 are arranged at intervals, one above the other, inside the housing frame 1. The two ends of the upper roll component 2 and the lower roll component 3 are respectively connected to the housing frame 1; the two ends of the upper roll component 2 and the lower roll component 3 are respectively positioned on the housing frame 1 through the bending cylinder component 4, and the bending cylinder force is provided through the bending cylinder component 4 to apply a reaction force to the roll component to solve the problem of roll deformation.

[0031] The hydraulic system 9 is installed on the arch frame 1 and is located directly below the lower roller assembly 3; the arc pad assembly 8 includes an upper arc pad 80 and a lower arc pad 81, the upper arc pad 80 is installed on the upper inner wall of the arch frame 1, and the lower arc pad 81 is installed on the upper roller assembly 2, and the upper arc pad 80 and the lower arc pad 81 are arranged vertically opposite to each other. The previous hard connection method between the arch assembly and the upper roller assembly 2 is changed to a connection method through the arc pad assembly 8. The arc pad assembly 8 cooperates with the bending cylinder assembly 4 to achieve the effect of large deformation of the roller with small bending cylinder force. At the same time, the elastic arc pad assembly 8 can also absorb external impact and vibration to a certain extent.

[0032] This kind of roller deformation deflection correction adaptive device, when working, the upward force of the hydraulic system 9 causes the lower roller assembly 3 to deform upward, and a reaction force is applied to the roller assembly through the bending cylinder assembly 4. Since the upper roller assembly 2 and the arch frame 1 are not connected in the original hard connection mode, but are connected through the arc pad assembly 8, the upper roller assembly 2 has space for upward deformation, thereby increasing the torque of the bending cylinder force. Specifically, when the upper roller assembly 2 is subjected to force, it can adaptively deform according to the size and direction of the external force, thereby reducing the impact force and vibration force on the mechanical structure or equipment, which is beneficial to improving the stability and reliability of the equipment, and also enables it to meet the needs of different working conditions, and achieve the effect of small bending cylinder force and large roller deformation; and the arc pad assembly 8 used in the present application has good stress distribution characteristics, which can reduce the stress concentration of the roller assembly and reduce material stress and deformation, which is beneficial to extending the service life of parts.

[0033] In the utility model, the upper arc pad 80 and the lower arc pad 81 both include a support pad block 82 and a docking portion 83. The support pad block 82 is provided with a screw hole 84. The support pad block 82 is installed on the mounting surface or the upper roller assembly 2 by means of a screw 10, and is easy to disassemble. The upper arc pad and the lower arc pad are respectively provided with a countersunk hole and a threaded hole for positioning. The countersunk hole and the threaded hole are connected. When installing the upper arc pad 80 and the lower arc pad 81, a bolt 86 is passed through the countersunk hole 85 and the threaded hole to position the upper arc pad 80 and the lower arc pad 81. After the installation is completed, the bolt 86 is removed to facilitate the provision of deformation space for the upper roller assembly.

[0034] In the utility model, a limit screw 11 is connected between the arch frame 1 and the upper roller assembly 2, and the limit screw 11 is arranged on one side of the arc pad assembly 8 close to the end of the upper roller assembly 2. Specifically, there is a certain gap between the limit screw 11 and the arch frame 1, and the limit screw 11 includes a head 12 and a screw 13. The diameter of the head 12 is larger than the diameter of the screw. A slot 14 for the head to be embedded is provided on the arch frame 1. The inner diameter of the slot 14 is slightly larger than the diameter of the head. The opening of the slot 14 faces downward, toward the bearing seat 7 at the end of the upper roller assembly 2. The bearing seat 7 is provided with a screw hole threadedly connected to the screw 13. The diameter of the opening of the slot 14 is smaller than the diameter inside the slot 14. Therefore, the head can move in the slot 14, providing conditions for the deformation of the upper roller assembly 2.

[0035] In the utility model, one side of the docking portion 83 is fixed to the support pad block 82, and the other side is in an arc shape; the other sides of the two docking portions 83 correspond to each other, and the other sides of the two docking portions 83 fit together. As the roller assembly is compressed and rebounded with the amount of deformation, the length of the fulcrum and the force is lengthened, achieving the effect of small force and large deformation, while absorbing part of the impact and vibration, thereby improving the stability and reliability of the equipment.

[0036] In the utility model, both ends of the upper roller assembly 2 and the lower roller assembly 3 are respectively installed on the arch frame 1 through the bearing seats 7, the lower arc pad 81 is fixed on the bearing seat 7 of the upper roller assembly 2, and the lower arc pads 81 are installed on the bearing seats 7 at both ends of the upper roller assembly 2, and the upper arc pads 80 are provided directly above the lower arc pads 81, and the arc pad assembly 8 is arranged directly above the hydraulic system 9, and the action rod of the hydraulic system 9 contacts the bottom surface of the bearing seat of the lower roller assembly. In this way, when the upward force of the hydraulic system 9 acts on the lower roller assembly 3, it can directly correspond to the arc pad assembly 8 located directly above, so that the arc pad assembly 8 can receive the extrusion force faster and more directly, and play a role quickly.

[0037] In the utility model, both ends of the upper roller assembly 2 and both ends of the lower roller assembly 3 are provided with a bending cylinder seat 6 for connecting the bending cylinder assembly 4, and the arch frame 1 is provided with a plurality of fixing seats 5 for connecting the bending cylinder assembly 4, and the plurality of bending cylinder seats 6 correspond to the plurality of fixing seats 5 one by one, and the two ends of the bending cylinder assembly 4 are respectively connected to the corresponding bending cylinder seat 6 and the fixing seat 5, and the bending cylinder assembly 4 connects the roller assembly and the arch frame 1, and can be more directly connected to an upward force exerted by the hydraulic system 9 on the roller assembly, thereby quickly applying a reaction force to the roller assembly and reducing the deformation of the roller assembly caused by deflection.

[0038] In this embodiment, hydraulic systems 9 are provided below both ends of the lower roller assembly 3, arc pad assemblies 8 corresponding to the two hydraulic systems 9 are provided at both ends of the upper roller assembly 2, two bending cylinder seats 6 are provided on both sides of the end of the upper roller assembly 2, and two bending cylinder seats 6 are also provided on both sides of the end of the lower roller assembly 3. That is to say, a total of eight bending cylinder seats 6 are provided, and correspondingly, eight fixed seats 5 are also provided on the arch frame 1, which are arranged one by one with the eight bending cylinder seats 6. The eight bending cylinder assemblies 4 are respectively connected to the eight fixed seats 5 and the eight bending cylinder seats 6, which play a role of positioning and providing bending cylinder force. The eight bending cylinder assemblies 4 cooperate with the two arc pad assemblies 8 to solve the problem of unclear roll disturbance deformation.

[0039] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
