Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, specifically to a roller surface cleaning scraper mechanism for a rolling mill and a rolling mill. Background Technology

[0002] Currently, the cleaning of the roll surfaces of lithium electrode sheet rolling mills is generally carried out by scrapers. Their function is to remove impurities such as carbon powder, dust, and other active particles from the roll surface, especially metal particles. This ensures that the upper and lower roll surfaces are clean and flat, providing continuous rolling of the electrode sheets, thereby extending the service life of the rolls and ensuring the thickness and surface flatness of the electrode sheets after rolling. Therefore, the cleaning effect of the scraper on the roll surface directly affects the quality of the lithium electrode sheets and the service life of the rolls, playing a key role in the normal operation of the mill.

[0003] The cleaning roller surface of the scraper mechanism is generally achieved by moving the scraper frame so that the blades come into contact with the roller surface to remove carbon dust and other active particles and other impurities. However, after the scraper blades have been used for a period of time, the blade edges may become worn, dull, or deformed. In order to ensure the cleanliness of the roller surface, the blades need to be replaced.

[0004] However, in order to facilitate waste discharge, the existing scrapers are generally tilted downwards at a 45-degree angle towards the roller surface. When replacing the blades, the blades can easily slip off after the locking mechanism is released, which can cause damage to the blades or even personal injury. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings and deficiencies in the prior art and to provide a roller surface cleaning scraper mechanism for a roller pressing mill and a roller pressing mill.

[0006] One embodiment of this utility model provides a roller surface cleaning scraper mechanism for a roll pressing mill, comprising: Mounting base; A tool holder, rotatably mounted on the mounting base, the tool holder having a mounting gap and a blade detachably mounted within the mounting gap, the cutting edge of the blade extending beyond the opening of the mounting gap; A translation drive assembly is connected to the mounting base and is used to drive the mounting base to move back and forth. The tool holder can be rotated relative to the mounting base to a cleaning position and a replacement position; When the blade holder is rotated to the cleaning position, the opening of the mounting gap is tilted downward toward the cleaning side of the mounting base, and the blade edge is tilted downward. When the blade holder is rotated to the replacement position, the opening of the mounting gap faces the side of the mounting base away from the cleaning side and is tilted upwards, and the blade edge is arranged tilted upwards.

[0007] In some optional embodiments, when the tool holder is rotated to the cleaning position, the angle of the opening of the mounting gap relative to the horizontal plane is 30° to 60°. When the tool holder is rotated to the replacement position, the angle of the opening of the installation gap relative to the horizontal plane is 30°~60°.

[0008] In some alternative embodiments, a damping structure is provided between the tool holder and the mounting base.

[0009] In some alternative embodiments, the damping structure includes a first damping gear and a second damping gear, the first damping gear being disposed on the tool holder, the second damping gear being rotatably disposed on the mounting base, and the second damping gear meshing with the first damping gear.

[0010] In some alternative embodiments, the tool holder is provided with a plurality of locking bolts that extend into the mounting gap to press the blade into the mounting gap.

[0011] In some alternative embodiments, the tool holder is provided with a plurality of handles.

[0012] In some alternative embodiments, the translation drive assembly includes a plurality of drive cylinders, the output ends of which are kinetically connected to the mounting base.

[0013] In some alternative embodiments, a limiting wheel is rotatably provided on the mounting base. The limiting wheel is located on the side of the tool holder away from the cleaning side. When the tool holder rotates to the replacement position, the limiting wheel abuts against the tool holder and restricts the rotation of the tool holder.

[0014] In some alternative embodiments, the roll surface cleaning scraper mechanism for the rolling mill further includes a dust collection assembly, which includes a dust collection box and a waste discharge pipe. The dust collection box is provided with a plurality of dust collection holes, and the waste discharge pipe is disposed on the mounting base. The dust collection holes are connected to the waste discharge pipe. When the blade holder is in the cleaning position, the blade is positioned above the dust collection box.

[0015] Another embodiment of this utility model provides a roll forming mill, including: a roll surface cleaning scraper mechanism for a roll forming mill as described above.

[0016] Compared to existing technologies, the roller surface cleaning scraper mechanism of this utility model for a rolling mill switches between cleaning and replacement positions via a scraper holder. After cleaning the roller surface, the scraper can be positioned with the scraper facing upwards, making it convenient for workers to remove and replace it. This prevents the blade from falling out of the installation gap and improves safety.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0024] Please see Figures 1 to 3 This utility model provides a roller surface cleaning scraper mechanism for a rolling mill, comprising: Mounting base 10; The tool holder 20 is rotatably mounted on the mounting base 10. The tool holder 20 is provided with a mounting gap 21 and a blade 22 that is detachably mounted in the mounting gap 21. The cutting edge of the blade 22 extends out of the opening of the mounting gap 21. Translation drive assembly 30 is driven to drive the mounting base 10 to move back and forth. The tool holder 20 can rotate relative to the mounting base 10 to a cleaning position and a replacement position; When the blade holder 20 is rotated to the cleaning position, the opening of the mounting gap 21 is tilted downward toward the cleaning side of the mounting base 10, and the blade edge of the blade 22 is tilted downward. When the blade holder 20 is rotated to the replacement position, the opening of the mounting gap 21 faces the side of the mounting base 10 away from the cleaning side and is tilted upwards, and the blade edge of the blade 22 is tilted upwards.

[0025] It should be noted that the clean side of the mounting base 10 refers to the side of the mounting base 10 facing the roll surface of the rolling mill.

[0026] The working principle of a roll surface cleaning scraper mechanism for a rolling mill according to an embodiment of the present invention is described below: Please see Figures 4 to 5 The blade holder 20 rotates to the cleaning position, and the translation drive assembly 30 drives the mounting base 10 to move toward the roll surface of the rolling mill, so that the cutting edge of the blade 22 abuts against the roll surface, and then the roll surface cleaning operation can be performed. When cleaning the roll surface, the cutting edge of the blade 22 is tilted downward, which helps to scrape impurities off the roll surface and make them fall off.

[0027] When the blade 22 needs to be replaced, the translation drive assembly 30 drives the mounting base 10 to move away from the roll surface of the rolling mill, so that the blade 22 is away from the roll surface. Then the blade holder 20 is rotated to the replacement position. At this time, the opening of the mounting gap 21 is tilted upward, and then the blade 22 can be disassembled. Since the opening of the mounting gap 21 is upward, the weight of the blade 22 will keep the blade 22 within the mounting gap 21 during the disassembly process and it will not easily fall off, thus preventing the blade 22 from falling off due to accident. Moreover, the blade edge is also facing upward, which enhances safety.

[0028] In some optional embodiments, when the tool holder 20 is rotated to the cleaning position, the angle of the opening of the mounting gap 21 relative to the horizontal plane is 30° to 60°. In this embodiment, the angle of the opening of the mounting gap 21 relative to the horizontal plane is 45 degrees downward. Of course, the orientation of the opening of the mounting gap 21 when the tool holder 20 is in the cleaning position can also be adjusted according to actual needs, and is not limited to the above-mentioned angle.

[0029] When the tool holder 20 is rotated to the replacement position, the angle of the opening of the installation gap 21 relative to the horizontal plane is 30°~60°. In this embodiment, the angle of the opening of the installation gap 21 relative to the horizontal plane is 45 degrees upward. Of course, the orientation of the opening of the installation gap 21 when the tool holder 20 is in the replacement position can also be adjusted according to actual needs, and is not limited to the above-mentioned angle.

[0030] In some optional embodiments, a damping structure 11 is provided between the tool holder 20 and the mounting base 10. The damping structure 11 slows down the rotation speed of the tool holder 20, thereby preventing accidental injury caused by the tool holder 20 rotating too fast and improving safety.

[0031] Please see Figure 6The specific structure of the damping structure 11 can be designed according to actual needs. For example, the tool holder 20 can be rotatably engaged with the mounting base 10 via a damping shaft. Alternatively, in this embodiment, the damping structure 11 includes a first damping gear 111 and a second damping gear 112. The first damping gear 111 is mounted on the tool holder 20, and the second damping gear 112 is rotatably mounted on the mounting base 10. The second damping gear 112 meshes with the first damping gear 111. When the tool holder 20 rotates, the second damping gear 112 also rotates with the tool holder 20, and the second damping gear 112 will drive the first damping gear 111 to rotate. The friction between the first damping gear 111 and the second damping gear 112 slows down the rotation of the first damping gear 111, thereby slowing down the rotation speed of the tool holder 20. Of course, a certain resistance can also be applied to the second damping gear 112, so that the second damping gear 112 can further apply damping force to the first damping gear 111, thereby more effectively reducing the rotation speed of the tool holder 20.

[0032] The specific installation method of the tool holder 20 and the blade 22 can be designed according to actual needs. For example, in some optional embodiments, the tool holder 20 is provided with multiple locking bolts. The locking bolts extend into the installation gap 21 to press the blade 22 into the installation gap 21, thereby achieving detachable locking of the blade 22 through the locking bolts. When removing the blade 22, the locking bolts are loosened, allowing the locking bolts to disengage from the blade 22. Then, because the blade 22 is held within the installation gap 21 by its own weight, it is not easy to fall off, thus improving safety.

[0033] In some alternative embodiments, the tool holder 20 is provided with a plurality of handles 23, which are convenient for the operator to hold and operate to rotate the tool holder 20, thus facilitating the operator's operation.

[0034] The specific structure of the translation drive assembly 30 can be designed according to actual needs. For example, the translation drive assembly 30 can be a lead screw drive assembly, a rotary motor translation drive assembly 30, a belt translation drive assembly 30, a cylinder translation drive assembly 30, or a linear motor translation drive assembly 30. In some optional embodiments, the translation drive assembly 30 includes several drive cylinders, and the output end of the drive cylinders is connected to the mounting base 10 for transmission.

[0035] In some alternative embodiments, a limiting wheel 12 is rotatably mounted on the mounting base 10. The limiting wheel 12 is located on the side of the tool holder 20 away from the cleaning side. When the tool holder 20 rotates to the replacement position, the limiting wheel 12 abuts against the tool holder 20 and restricts the rotation of the tool holder 20. Because the limiting wheel 12 can rotate, the friction between the tool holder 20 and the limiting wheel 12 can be reduced.

[0036] In some optional embodiments, the roll surface cleaning scraper mechanism for the rolling mill also includes a dust collection assembly 40, which includes a dust collection box 41 and a waste discharge pipe 42. The dust collection box 41 is provided with a plurality of dust collection holes 411, and the waste discharge pipe 42 is provided on the mounting base 10. The dust collection holes 411 are connected to the waste discharge pipe 42. When the blade holder 20 is in the cleaning position, the blade 22 is above the dust collection box 41. The waste discharge pipe 42 is connected to a negative pressure suction device. The negative pressure suction device draws in the dust collection holes 411 to generate negative pressure. When the blade 22 abuts against the roll surface for cleaning, impurities that fall from the roll surface will be sucked into the dust collection holes 411 and then discharged through the waste discharge pipe 42.

[0037] The aforementioned roller surface cleaning scraper mechanism for a rolling mill can be applied to a rolling mill, which includes: the roller surface cleaning scraper mechanism for a rolling mill as described above.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
