Description

Technical Field

[0001] This utility model relates to the field of rolling mill stand technology, specifically a rolling mill stand for lithium battery electrode production. Background Technology

[0002] A rolling mill is a piece of equipment that realizes the metal rolling process. It generally refers to the equipment that completes the entire process of rolling production. A conventional rolling mill is mainly composed of rollers, stands, roller gap adjustment devices, roller temperature adjustment devices, transmission devices, lubrication systems, control systems, and roll removal devices. In addition to the main components and devices of a conventional rolling mill, a precision rolling mill adds devices to ensure rolling accuracy.

[0003] For example, Chinese Patent CN117531838A (A Rolling Mill Stand) includes at least two rolls rotatably supported in a reciprocating rolling mill stand. The rolling mill stand preferably has at least one overload protection device configured as a hydraulic overload protection device. The overload protection device includes at least one push rod for hydraulic preloading and a hydraulic system. The push rod acts parallel to the rolling force on the roll mounting. The hydraulic system has devices for generating hydraulic preload and devices for unloading the preload when a predetermined overload is exceeded. This invention also relates to an overload protection device and a method for controlling the overload protection device.

[0004] However, the distance between the front and rear stands of existing rolling mill stands is fixed. When adjustments are needed based on the rolling rolls, it is necessary to replace the fixed columns of different sizes, which is time-consuming and labor-intensive, resulting in poor flexibility. Therefore, it does not meet the current requirements. In response, we have proposed a rolling mill stand for lithium battery electrode production. Utility Model Content

[0005] The purpose of this utility model is to provide a rolling mill stand for lithium battery electrode production, so as to solve the problem mentioned in the background art that the distance between the front and rear stands of the existing rolling mill stands is fixed. When it is necessary to adjust according to the rolling rolls, it is necessary to replace the fixed columns of different sizes, which is time-consuming and labor-intensive, resulting in poor flexibility.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rolling mill frame for lithium battery electrode production, comprising: a first frame, a second frame disposed at the rear of the first frame, guide grooves disposed on both sides of the first and second frames, movable guide columns disposed in the guide grooves, one side surface of the guide columns being an extrusion plane, fixing knobs disposed on both sides of the first and second frames, a movable base disposed at the lower end of the first frame, and a positioning base disposed at the lower end of the second frame.

[0007] Preferably, both sides of the first and second frames are provided with knob grooves for fixing the threaded connection of the knobs.

[0008] Preferably, the lower surface of the movable base is provided with a rotating groove, the interior of the rotating groove is provided with a rotating column, and both ends of the rotating column are provided with rotating shafts for rotating the rotating column.

[0009] Preferably, mounting plates are welded to both sides of the positioning base, and the mounting plates are fixed to the ground by external grounding bolts.

[0010] Preferably, the front and rear ends of the movable base and the positioning base are provided with fixing plates, and both ends of the fixing plates are provided with fixing screws. The movable base and the positioning base are fixed to the first frame and the second frame respectively by the fixing plates and fixing screws.

[0011] Preferably, the front surfaces of both the first frame and the second frame are provided with roll mounting grooves, and roll adjusting grooves are provided on both sides of the roll mounting grooves.

[0012] Preferably, the upper ends of the first frame and the second frame are each provided with a top cover, and the two ends of the two top covers are fixed to the first frame and the second frame respectively by a fixed component.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention fixes the second frame by setting guide grooves on both sides of the first and second frames, inserting guide posts into the guide grooves, and fixing the mounting plate to the ground with external grounding bolts. Then, four guide posts are inserted into the guide grooves of the second frame, with one end of each post passing through the second frame and continuing into the guide groove of the first frame, with the extrusion surface facing the knob slot. The distance between the first and second frames is adjusted along the guide posts. During adjustment, the second frame is already fixed, providing a positioning effect, while the guide posts provide an orientation effect, preventing the first frame from shifting during adjustment and improving stability. After adjusting the distance between the first and second frames according to the required roll length, the fixing knob is tightened. One end of the fixing knob presses and fixes the extrusion surface of the guide posts, thus fixing the first and second frames. This invention is suitable for installing rolls of different sizes. Compared to existing methods where both frames are fixed, it improves flexibility and solves the problem that the distance between the front and rear frames of existing rolling mills is fixed, requiring the replacement of different sized fixing posts when adjustments are needed based on the roll size, which is time-consuming, labor-intensive, and results in poor flexibility.

[0015] By setting a rotating column inside the rotating groove on the lower surface of the movable base, and setting a rotating shaft at both ends of the rotating column for rotating the column, the rotating column rotates due to friction when the first frame is adjusted, thereby improving the smoothness of the adjustment of the first frame and avoiding friction damage to the lower surface of the movable base. Furthermore, the movable base and the positioning base are fixed to the first frame and the second frame respectively by fixing plates and fixing screws, which facilitates the fixing and disassembly of the movable base and the positioning base and improves the convenience of replacement.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4 An embodiment of this utility model provides a rolling mill frame for lithium battery electrode production, comprising: a first frame 1, a second frame 2 disposed at the rear of the first frame 1, guide grooves 6 disposed on both sides of the first frame 1 and the second frame 2, movable guide posts 7 disposed in the guide grooves 6, one side surface of the guide posts 7 being an extrusion plane 8, fixing knobs 9 disposed on both sides of the first frame 1 and the second frame 2, a movable base 10 disposed at the lower end of the first frame 1, a positioning base 11 disposed at the lower end of the second frame 2, knob grooves 17 for fixing the threaded connection of the knobs 9 disposed on both sides of the first frame 1 and the second frame 2, mounting plates 15 welded to both sides of the positioning base 11, and the mounting plates 15 being fixed to the ground by external grounding bolts.

[0023] After one end of the guide post 7 passes through the second frame 2, it continues to be inserted into the guide groove 6 of the first frame 1, with the side having the extrusion surface 8 facing the knob groove 17. Adjust the distance between the first frame 1 and the second frame 2 along the guide post 7. During adjustment, since the second frame 2 is already fixed, it has a positioning effect, and the guide post 7 has an orientation effect, preventing the first frame 1 from shifting during adjustment and improving stability. After adjusting the distance between the first frame 1 and the second frame 2 according to the required roll length, tighten the fixing knob 9. The extrusion surface 8 of the guide post 7 is extruded and fixed through one end of the fixing knob 9, thereby fixing the first frame 1 and the second frame 2. This is suitable for the installation of rolls of different sizes and improves flexibility.

[0024] Please see Figure 1 , 2 4. A rotating groove 16 is provided on the lower surface of the movable base 10. A rotating column 14 is provided inside the rotating groove 16. Both ends of the rotating column 14 are provided with rotating shafts 19 for rotating the rotating column 14. When adjusting the first frame 1, the rotating column 14 receives friction and rotates, thereby improving the smoothness of the adjustment of the first frame 1 and avoiding friction damage to the lower surface of the movable base 10.

[0025] Please see Figure 1 The front and rear ends of the movable base 10 and the positioning base 11 are provided with fixing plates 12, and the two ends of the fixing plates 12 are provided with fixing screws 13. The movable base 10 and the positioning base 11 are fixed to the first frame 1 and the second frame 2 respectively by fixing plates 12 and fixing screws 13, which facilitates the fixing and disassembly of the movable base 10 and the positioning base 11 and improves the convenience of replacement.

[0026] Please see Figure 1 The front surfaces of the first frame 1 and the second frame 2 are both provided with roll mounting grooves 18, and roll adjusting grooves 5 are provided on both sides of the roll mounting grooves 18. The upper ends of the first frame 1 and the second frame 2 are both provided with top covers 3. The two ends of the two top covers 3 are fixed to the first frame 1 and the second frame 2 respectively by the fixed components 4. The fixed ends of the rolls are inserted along the roll mounting grooves 18. The fixed position of the fixed ends of the rolls is adjusted by the roll adjusting grooves 5, realizing the position adjustment between multiple rolls and improving flexibility. The top covers 3 are fixed by the fixed components 4 to cover the top of the roll mounting grooves 18 and improve safety.

[0027] Working principle: In use, the movable base 10 and the positioning base 11 are fixed to the first frame 1 and the second frame 2 respectively by the fixing plate 12 and the fixing screw 13. The mounting plate 15 is fixed to the ground by the external grounding bolt, thus fixing the second frame 2. Then, four guide posts 7 are inserted into the guide grooves 6 of the second frame 2, and one end of the guide post 7 passes through the second frame 2 and continues to be inserted into the guide groove 6 of the first frame 1, with the side with the pressing surface 8 facing the knob groove 17. The distance between the first frame 1 and the second frame 2 is adjusted along the guide posts 7. During adjustment, since the second frame 2 is already fixed, it has a positioning effect, and the guide posts 7 have a directional effect, preventing the first frame 1 from shifting during adjustment and improving stability. When frame 1 is in operation, the rotating column 14 rotates due to friction, thereby improving the smoothness of the adjustment of the first frame 1 and preventing friction damage to the lower surface of the moving base 10. After adjusting the distance between the first frame 1 and the second frame 2 according to the required roller length, tighten the fixing knob 9. The pressing plane 8 of the guide column 7 is pressed and fixed through one end of the fixing knob 9, thereby fixing the first frame 1 and the second frame 2. Then, the fixed end of the roller is inserted along the roller mounting groove 18. The fixed position of the fixed end of the roller is adjusted by the roller adjusting groove 5, realizing the position adjustment between multiple rollers and improving flexibility. The top cover 3 is fixed by the fixing component 4 to cover the top of the roller mounting groove 18 and improve safety.
