Description

Technical Field

[0001] This utility model relates to the field of roller pressing equipment technology, specifically a dry electrode film forming heating roller press. Background Technology

[0002] Roller presses, also known as extrusion mills or roller mills, are high-efficiency and energy-saving equipment that crushes and grinds materials based on the principle of high-pressure extrusion. They are widely used in building materials, mining, chemical and other fields. Their core function is to extrude block and granular materials into dense cakes, while simultaneously completing the initial crushing or deep grinding of materials, thus reducing energy consumption and improving efficiency for subsequent processing (such as ball mill grinding).

[0003] Among them, the dry electrode film heating roller press is a core piece of equipment designed specifically for the dry electrode process of lithium-ion batteries. It achieves solvent-free electrode manufacturing through the synergistic effect of heating and rolling. Its core function is to directly press the mixed powder of active materials (such as ternary materials and lithium iron phosphate), conductive agents (carbon black and carbon nanotubes) and binders into high-strength, high-pressure compaction electrode films, while optimizing the material interface bonding force through precise temperature control.

[0004] In the existing dry electrode film heating roller press operation process, after each processing operation, the steel roller needs to be manually cleaned by the staff. The core purpose of this operation is to reduce the residue and adhesion of impurities on the surface of the steel roller, thereby effectively ensuring the quality of the film in the subsequent secondary processing operation of the equipment. However, on the other hand, frequent manual wiping not only increases the labor input, but also significantly reduces the overall production efficiency. Utility Model Content

[0014] The present invention is further configured such that the inner wall of the toothed strip is provided with a gear, and the toothed strip and the gear mesh with each other, and the gear is located at one end of the fixed plate via a rotating rod.

[0015] Preferably, the rotation of the drive motor is caused by the meshing of gears and toothed racks, which drives the rotation of multiple sets of injection blocks to clean the positioning ring.

[0016] The present invention is further configured such that a liquid injection block is installed at the other end of the rotating rod, and the liquid injection block is made of a flexible material.

[0017] Preferably, the outer wall of the contact block is cleaned to reduce the impact of secondary operations on the steel roller.

[0018] The present invention is further configured such that a positioning ring is movably installed on the inner wall of the contact block, and both the contact block and the positioning ring are arc-shaped.

[0019] Preferably, the positioning ring is made to fit against the outer wall of the steel roller, which effectively improves the efficiency of cleaning the positioning ring.

[0020] The present invention is further configured such that the outer wall of the fixing plate is provided with multiple sets of through holes and grooves, and the outer wall of the positioning ring is provided with multiple sets of protrusions.

[0021] Preferably, the position of the connecting rod is limited by setting multiple sets of through holes, and the connecting rod is sleeved in the through holes and connected to them.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] First embodiment:

[0037] Please see Figures 1-5 The device includes a housing 1, with a steel roller 2 at one end and a protective shell 3 at the other end. A cleaning assembly is installed on the inner wall of the protective shell 3. This assembly includes a positioning ring 9, contact blocks 10, and injection blocks 11. A fixing plate 8 is installed at one end of the positioning ring 9, and a connecting rod 4 is movably fitted onto the inner wall of the fixing plate 8. A limit plate 5 is installed at the other end of the connecting rod 4. The cleaning assembly cleans the outer wall of the steel roller 2, ensuring the quality of the diaphragm in subsequent secondary processing operations while significantly reducing manual wiping of the steel roller 2, effectively improving overall operational efficiency. The drive motor 12 and toothed rack 7 drive the rotation of multiple injection blocks 11, cleaning the outer wall of the contact blocks 10, reducing the impact of secondary operations on the steel roller 2, and consequently reducing the frequency of regular cleaning of the contact blocks 10 by personnel, thus improving the practicality of the cleaning assembly.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figures 2-5 An electric push rod 6 is provided at the end of the limiting plate 5 away from the connecting rod 4, and multiple sets of connecting rods 4 are connected to the limiting plate 5. The electric push rod 6 drives the limiting plate 5 to move, which in turn causes the connecting rod 4 to push the positioning ring 9 to move, effectively improving the working efficiency of the component.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figures 2-5 The limiting plate 5 and the electric push rod 6 are movably connected to the inner wall of the device housing 1. The limiting plate 5 is I-shaped. The shape of the limiting plate 5 effectively improves the stability of the connection between the connecting rod 4 and the limiting plate 5, and improves the synchronization of multiple positioning rings 9.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5One end of the fixed plate 8 is equipped with a drive motor 12, and the output end of the drive motor 12 is fitted with a toothed rack 7. The drive motor 12 drives the toothed rack 7 to rotate, causing multiple sets of rotating rods to rotate, thus reducing the cost of the equipment.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figures 2-5 The inner wall of the toothed rack 7 is provided with gears, and the toothed rack 7 and the gears mesh with each other. The gears are located at one end of the fixed plate 8 through the rotating rod. The meshing of the gears with the toothed rack 7 causes the rotation of the drive motor 12 to drive the rotation of multiple sets of liquid injection blocks 11, thereby cleaning the positioning ring 9.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figures 3-5 The other end of the rotating rod is equipped with a liquid injection block 11, which is made of flexible material. The liquid injection block 11 cleans the outer wall of the contact block 10 and reduces the impact of the secondary operation of the contact block 10 on the steel roller 2.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 A positioning ring 9 is movably installed on the inner wall of the contact block 10, and both the contact block 10 and the positioning ring 9 are arc-shaped, so that the positioning ring 9 fits against the outer wall of the steel roller 2, effectively improving the cleaning efficiency of the positioning ring 9.

[0044] Second embodiment:

[0045] Please see Figure 5 The difference between Embodiment 2 and Embodiment 1 is that, while retaining the features of Embodiment 1, multiple sets of grooves 14 are provided on the outer wall of the fixing plate 8, and multiple sets of protrusions 15 are installed on the end of the positioning ring 9 near the fixing plate 8. The grooves 14 and protrusions 15 engage with each other, which effectively improves the stability of the positioning ring 9 and the contact block 10 when not in operation, reduces the displacement of the contact block 10, and effectively improves the service life of the cleaning component.

[0046] In practical operation, this utility model is as follows:

[0047] When the equipment finishes processing the material and the cleaning component is needed to clean the outer wall of the steel roller 2, the electric push rod 6 is first started by the control button on the equipment. The electric push rod 6 drives the limit plate 5 to move, which in turn drives the multiple sets of connecting rods 4 to move the multiple sets of positioning rings 9. This causes the contact block 10 to contact the outer wall of the steel roller 2 and clean the outer wall of the steel roller 2. If the surface of the steel roller 2 is not cleaned properly, the operator can rotate the steel roller 2 to perform a secondary cleaning of the outer wall of the steel roller 2.

[0048] When the contact block 10 finishes cleaning the outer wall of the steel roller 2, the electric push rod 6 retracts inward, causing the connecting rod 4 to move so that the positioning ring 9 and the contact block 10 are located on the inner wall of the protective shell 3, and the contact block 10 is in contact with the liquid injection block 11. Then the drive motor 12 is started. The rotation of the drive motor 12 drives multiple sets of gears to rotate, which in turn drives multiple sets of liquid injection blocks 11 to rotate synchronously, cleaning the outer wall of the contact block 10. The liquid injection block 11 is made of flexible material, which can clean the outer wall of the contact block 10 from multiple angles. The liquid injection block 11 contains cleaning liquid to clean the outer wall of the contact block 10.

[0049] Furthermore, the outer wall of the fixing plate 8 is provided with multiple sets of grooves 14, and the outer wall of the positioning ring 9 is also provided with multiple sets of protrusions 15. The protrusions 15 are fitted into the grooves 14, so that the fixing plate 8 limits the position of the positioning ring 9, reduces the position of the positioning ring 9, and thus improves the stability of the positioning ring 9 and the contact block 10.
