[0001] The utility model relates to the technical field of battery preparation, in particular to a scraper structure with a scraper blade capable of being quickly replaced. Background Art

[0002] In the production and manufacturing process of lithium-ion batteries, the rolling process is very critical. However, during the normal operation of the roller press, the electrode coating, especially the negative electrode coating, will stick to the surface of the roller, which will have an adverse effect on the electrode rolling process, so a scraper mechanism must be installed to scrape it off.

[0003] The current scraper mechanism structure is to drive the scraper blade to extend and retract through a cylinder to achieve contact with the roller for scraping. For example, Chinese patent announcement number "CN213887237U" discloses a scraper device for rolling lithium battery pole pieces, which includes a scraper assembly for attaching scraper material to the battery pole pieces and a propulsion assembly for driving the scraper assembly to move; the scraper assembly includes a guide wheel, a scraper, and a scraper fixing plate for fixing the scraper.

[0004] However, when replacing the scraper blade, the existing scraper mechanism needs to remove the cylinder and manually rotate the scraper seat to take out the old scraper blade and install the new scraper blade. The action is cumbersome, time-consuming and labor-intensive. Therefore, how to further replace the scraper blade more conveniently and quickly is worthy of further exploration. Summary of the Invention

[0005] The utility model aims to solve the shortcomings of the prior art such as manually rotating the scraper seat to remove the old scraper blade, which is cumbersome, and proposes a scraper structure that can quickly replace the scraper blade.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A scraper structure with a quickly replaceable scraper blade is designed and installed on a roller press, comprising a support assembly and a scraper assembly, wherein the scraper assembly contacts the roller of the roller press;

[0008] The scraper assembly is rotationally connected to the support assembly, and a driving assembly is also provided between the scraper assembly and the support assembly. The driving assembly is used to drive the scraper assembly to rotate circumferentially to control the contact and separation of the scraper assembly and the roller.

[0009] Furthermore, the support assembly includes two spaced-apart mounting plates, and the scraper assembly is rotatably disposed between the two mounting plates.

[0010] Furthermore, a longitudinal waist hole and a longitudinal groove are formed on the end surface of one of the mounting plates, and a longitudinal guide block is slidably connected in the longitudinal groove;

[0011] A transverse waist hole and a transverse groove are provided on the end surface of the other mounting plate, and a transverse guide block is slidably connected in the transverse groove.

[0012] Furthermore, the scraper assembly includes a scraper seat, and the scraper seat rotates between the two mounting plates via a rotating shaft;

[0013] Wherein, a pressure plate is fixed on the scraper seat by a fastener, and a scraper blade is clamped between the scraper seat and the pressure plate.

[0014] Furthermore, a protective block is provided at the bottom of the knife pressing plate.

[0015] Furthermore, the driving assembly includes a gear fixedly mounted on the rotating shaft, a rack is slidably connected to the mounting plate, the rack is engaged with the gear, and a driving member for driving the rack to move up and down is also provided on the mounting plate.

[0016] Furthermore, a rack pressing plate is fastened to the end surface of the mounting plate, and the rack pressing plate has a channel for the rack to pass through.

[0017] Furthermore, a windshield is fixed on the end surface of the mounting plate, and the windshield is sleeved on the outside of the meshing portion between the rack and the gear.

[0018] The utility model proposes a scraper structure that can quickly replace the scraper blade. The beneficial effect is that: in the utility model, two mounting plates are fixed on the wall panels on both sides of the roller press, and the scraper seat and the scraper blade installed on the scraper seat can be rotated around the rotating shaft through the driving component. When the scraper blade needs to be replaced, the driving part can be directly rotated out to allow the old scraper blade to be directly removed and replaced with a new scraper blade. After the replacement is completed, the driving part is allowed to rotate the scraper blade until it fits with the roller to complete the blade changing operation. When replacing the scraper blade, there is no need to disassemble the cylinder and manually rotate the scraper seat out, thereby saving time and manpower and improving the convenience of operation.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-3 An embodiment of the present invention discloses a scraper structure with a quickly replaceable scraper blade, which is installed on a roller press. Specifically, the scraper structure includes a support assembly 1 and a scraper assembly 2, wherein at least a portion of the scraper assembly 2 is in contact with a roller 3 of the roller press;

[0025] The scraper assembly 2 is rotatably connected to the support assembly 1, and a drive assembly 4 is also provided between the scraper assembly 2 and the support assembly 1. The drive assembly 4 is used to drive the scraper assembly 2 to rotate circumferentially to control the contact and separation of the scraper assembly 2 and the roller 3. That is, in this embodiment, the scraper blade 24 of the scraper assembly 2 is used to contact the roller 3 to scrape off the electrode coating adhered to the surface of the roller.

[0026] In some embodiments, the support assembly 1 in the present invention includes two spaced-apart mounting plates 11, and the scraper assembly 2 rotates between the two mounting plates 11. Furthermore, in this embodiment, a hole is opened on the end face of the mounting plate 11, and a bearing is embedded in the hole, which rotates through the bearing and the rotating shaft 22 to improve the rotation stability of the scraper assembly 2.

[0027] Specifically, in this embodiment, a longitudinal waist hole 12 and a longitudinal groove are opened on the end surface of one of the mounting plates 11, and a longitudinal guide block 13 is slidably connected in the longitudinal groove;

[0028] A transverse waist hole 14 and a transverse groove are formed on the end surface of the other mounting plate 11 , and a transverse guide block 15 is slidably connected in the transverse groove.

[0029] When fixing, the longitudinal guide block 13 and the transverse guide block 15 are installed and guided in the X and Y directions. After the longitudinal guide block 13 and the transverse guide block 15 are pre-fixed, since the longitudinal guide block 13 and the transverse guide block 15 both have the ability to slide, when further fixed, the longitudinal waist hole 12 and the transverse waist hole 14 can be used to adjust the position of the entire scraper structure in X and Y by a small distance, thereby improving the adaptability of the installation and avoiding the problem of difficulty in installation due to misalignment of the wire holes.

[0030] On the basis of the above embodiment, the scraper assembly 2 in the present invention includes a scraper seat 21, and the scraper seat 21 rotates between the two mounting plates 11 via a rotating shaft 22;

[0031] A pressure plate 23 is fixed to the scraper seat 21 via fasteners. In this embodiment, the fasteners are preferably bolts. A scraper blade 24 is clamped between the scraper seat 21 and the pressure plate 23 .

[0032] Furthermore, in order to protect the scraper assembly 2, a protective block 25 is provided at the bottom of the pressure plate 23 in this embodiment. The protective block 25 is preferably a nylon block, which can protect the bottom of the pressure plate 23 by virtue of its own elasticity.

[0033] In addition, in the present invention, the driving assembly 4 includes a gear 41 fixedly mounted on the rotating shaft 22, a rack 42 is slidably connected to the mounting plate 11, and the rack 42 is engaged with the gear 41, wherein the mounting plate 11 is also provided with a driving member 43 that drives the rack 42 to move up and down.

[0034] In this embodiment, the above-mentioned driving member 43 is preferably a cylinder, which is fixed on the mounting plate 11. Those skilled in the art know that in other embodiments, the driving member 43 can also be designed as a hydraulic cylinder or an electric push rod to achieve the same technical effect.

[0035] In more detail, during operation, the rack 42 is driven up and down by the driving member 43, and the rack 42 drives the gear 41 to rotate, thereby driving the rotating shaft 22 to rotate. When the rotating shaft 22 rotates circumferentially, it will drive the scraper blade 24 to rotate and separate from the roller 3. After the scraper blade 24 rotates to the threshold distance, the scraper blade 24 can be disassembled and replaced by removing the pressure plate 23. Compared with the method of first disassembling the cylinder and then manually rotating the scraper seat to replace the scraper blade in the prior art, the operation is simpler.

[0036] On the basis of the above embodiment, in the utility model, a rack pressure plate 44 is fastened on the end face of the mounting plate 11, and the rack pressure plate 44 has a channel for the rack 42 to pass through. The channel is designed to provide a sliding space for the rack 42 and to guide and constrain the up and down movement of the rack 42. Furthermore, in this embodiment, the rack pressure plate 44 is fastened to the mounting plate 11 by bolts.

[0037] The above descriptions all take a single driving assembly 4 as an example. In this embodiment, two driving assemblies 4 are designed and are respectively located on opposite surfaces of two mounting plates 11 to enhance the stable driving of the scraper assembly 2 .

[0038] Furthermore, in this embodiment, a windshield 45 is fixed on the end face of the mounting plate 11. The windshield 45 is mounted on the outside of the meshing portion between the rack 42 and the gear 41. The windshield 45 is designed to protect the mechanical movement, which can effectively improve the movement installation performance of the structure and prevent foreign matter from entering between the rack 42 and the gear 41 and causing jamming.

[0039] In summary, in the present invention, by fixing two mounting plates 11 on the wall panels on both sides of the roller press, the scraper seat 21 and the scraper blade 24 installed on the scraper seat 21 can be rotated around the rotating shaft 22 through the driving component 4. When the scraper blade 24 needs to be replaced, the driving part 43 can be directly used to rotate the scraper seat 21 out, so that the old scraper blade 24 can be directly removed and replaced with a new scraper blade 24. After the replacement is completed, the driving part 43 is used to rotate the scraper blade 24 until it fits with the roller 3 to complete the blade changing operation. When replacing the scraper blade 24, there is no need to disassemble the cylinder and manually rotate the scraper seat 21, thereby saving time and manpower and improving the convenience of operation.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
