Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating roller cleaning technology, and in particular to a coating roller cleaning device. Background Technology
[0002] In the lithium battery coating process, active materials need to be coated on the surfaces of the positive and negative electrode materials of the lithium battery to improve the battery's capacity and performance to a certain level to meet specific usage requirements.
[0003] When the coating machine is working, if it encounters a slurry with too low viscosity, the slurry with low viscosity will have increased fluidity. Under the action of gravity or the rotation of the coating roller, the slurry will overflow from the gap between the foam and the steel roller. The overflowing slurry will adhere to the surface of the coating roller and then be coated onto the electrode tabs, resulting in a decrease in the coating qualification rate.
[0004] In the prior art, to solve the problem of slurry easily adhering to the coating roller of the coating machine, a flexible cleaning material is used to contact the coating roller so that the slurry adhering to the coating roller surface is wiped off by the flexible cleaning material. However, in the above-mentioned problem, due to the pressing and wiping of the flexible material, the force cannot be controlled, which can easily cause excessive force, increase the friction between the flexible material and the coating roller surface, and increase the wear of the coating roller.
[0005] Therefore, this application addresses the problem that when a coating machine encounters a low-viscosity slurry, the pressure between the flexible material and the coating roller surface is difficult to control, which can easily increase the friction on the coating roller surface. Utility Model Content
[0006] The main purpose of this invention is to provide a coating roller cleaning device, which aims to adjust the pressure between the flexible material and the coating roller surface, reduce the friction on the coating roller surface, and reduce the wear on the coating roller surface.
[0007] To achieve the above objectives, this utility model proposes a coating roller cleaning device, including a cleaning assembly for wiping the surface of the coating roller, the cleaning assembly comprising:
[0008] The shell has a groove.
[0009] A flexible element is disposed within a groove in the housing, with one end extending from an opening in the groove; and
[0010] Fiber fabric is attached to the housing and wraps the portion of the flexible element that extends out of the groove;
[0011] The flexible component is capable of deformation and can stretch the fibrous fabric with elastic force.
[0012] In the above scheme, the fiber cloth is close to the surface of the coating roller. The nano sponge is deformed due to the compression of the fiber cloth, thus buffering the compression between the fiber cloth and the coating roller. At the same time, the deformation of the fiber cloth due to compression increases the contact area between the fiber cloth and the coating roller, increasing the slurry wiping area on the coating roller surface. When the slurry is on the fiber cloth, it can penetrate the fiber cloth and be absorbed by the nano sponge, which can reduce the amount of slurry on the fiber cloth and prevent secondary adhesion.
[0013] Furthermore, the cross-section of the shell is U-shaped, semi-circular, V-shaped, trapezoidal, or T-shaped. Different cross-sectional shapes of the shell can be designed according to the shape of the flexible component, or the cross-sectional shape of the shell can be determined according to the frequency of fiber fabric replacement.
[0014] Furthermore, it also includes a slide rail, on which at least one of the housings is slidably mounted. Preferably, two housings are provided, because overflow is prone to occur at both ends of the coating roller. The housings are adjusted along the slide rail to align the fiber cloth with both ends of the coating roller, thereby achieving the purpose of cleaning the coating roller slurry.
[0015] Furthermore, the bottom of the housing is provided with a slider equipped with a positioning element, and the slider is slidably connected to the slide rail. The sliding of the slider and the slide rail improves the stability of the housing's movement. The positioning element can be a pin, bolt, or elastic plate. When the slider moves to a designated position, the pin, bolt, or elastic plate engages with the slide rail to fix the housing in the designated position, facilitating the positioning and cleaning of the slurry at the end of the coating roller.
[0016] Furthermore, the fiber fabric is a dust-free cloth, non-woven fabric, or cleaning cloth.
[0017] Furthermore, it also includes a lifting device for driving the housing to move vertically. The lifting device can drive the slide rail to rise and fall, thereby driving the fiber cloth to adhere to the surface of the coating roller, and can also drive the housing to rise and fall, thereby adhering the fiber cloth to the surface of the coating roller to meet the wiping work of the coating roller.
[0018] Furthermore, the lifting device includes a screw threadedly connected to the slide rail and an adjusting device that drives the screw to rotate. The adjusting device can be a motor driven at the end of the screw, or a combination of a motor and a transmission structure. The transmission structure can be a pair of bevel gears meshing with each other to adjust the installation direction of the motor, or a pair of spur gears meshing to place the motor output shaft and the screw axis at different positions for easy installation.
[0019] Furthermore, the fiber fabric is detachably connected to the housing. The end of the fiber fabric can be directly hung on the side of the housing, or it can be fixed to the side of the housing with bolts, making it convenient to replace the fiber fabric after use.
[0020] Furthermore, elastic elements are provided at both ends of the fiber fabric, and the elastic elements hold the ends of the fiber fabric onto the housing.
[0021] Furthermore, the elastic element is a spring plate equipped with a locking buckle, which holds the end of the fiber fabric against the side of the housing. Specifically, the elastic element is a spring plate equipped with a locking buckle, which can release the spring plate to facilitate replacement of the fiber fabric. The spring plate holds the end of the fiber fabric against the side of the housing, and a fixing ear is also provided on the side of the housing to facilitate the spring plate to press and fix the end of the fiber fabric.
[0022] The above technical solution has the following advantages:
[0023] This invention installs a flexible component in the groove of the housing, and wraps the extension of the flexible component with fiber cloth. When the fiber cloth is pressed against the surface of the coating roller, the nano sponge deforms due to the compression of the fiber cloth, thereby buffering the pressure between the fiber cloth and the coating roller. It can automatically adjust the pressure between the flexible material and the surface of the coating roller, reduce the friction on the surface of the coating roller, and reduce the wear on the surface of the coating roller.
[0024] The fiber fabric deforms due to compression, increasing the contact area between the fiber fabric and the coating roller. This increases the slurry wiping area on the coating roller surface. When the slurry is on the fiber fabric, it can penetrate the fabric and be absorbed by the nano sponge, reducing the amount of slurry on the fiber fabric and preventing secondary adhesion.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain this utility model and do not constitute a limitation on this utility model.
[0030] like Figure 1As shown, a coating roller cleaning device includes a cleaning assembly for wiping the surface of the coating roller. The cleaning assembly includes a housing 3, a flexible member 2, and a fiber cloth 1. The housing 3 has a groove. The flexible member 2 is disposed in the groove of the housing 3, and one end extends out from the opening of the groove. The fiber cloth 1 is connected to the housing 3 and wraps the part of the flexible member 2 that extends out of the groove. The flexible member 2 is deformable and stretches the fiber cloth 1 with elastic force.
[0031] The cleaning component can wipe the slurry on the surface of the coating roller to ensure the pass rate of subsequent coating. Specifically, the housing 3 is used to place the flexible component 2, which is a deformable material, such as sponge, foam, or hydrophobic material. In this application, nano-sponge is preferred. The nano-sponge is placed in the groove of the housing 3 and partially extends out of the groove. The fiber cloth 1 wraps around the extended part of the nano-sponge. The fiber cloth 1 is a dust-free cloth, non-woven fabric, or cleaning cloth. When the fiber cloth 1 is close to the surface of the coating roller, the nano-sponge deforms due to the compression of the fiber cloth 1, thereby buffering the pressure between the fiber cloth 1 and the coating roller. At the same time, the fiber cloth 1 deforms due to compression, and the contact area between the fiber cloth 1 and the coating roller increases, increasing the slurry wiping area on the surface of the coating roller. When the slurry is in the fiber cloth 1, the slurry can penetrate the fiber cloth 1 and be absorbed by the nano-sponge, which can reduce the slurry on the fiber cloth 1 and prevent secondary adhesion.
[0032] like Figure 1 As shown, the cross-section of the shell 3 is U-shaped, semi-arc, V-shaped, trapezoidal, or T-shaped. The groove of the shell 3 can be designed with different shapes according to the shape of the flexible part 2 in order to place the flexible part 2. The cross-sectional shape of the shell 3 can also be determined according to the frequency of replacement of the fiber fabric 1. Taking the cross-section as U-shaped as an example, the flexible part 2 can be placed stably in the shell 3. Under the action of compression, the slurry adsorbed inside the flexible part 2 gradually sinks, which also improves the adsorption capacity of subsequent slurry. The flexible part 2 is preferably placed directly in the groove of the shell 3, which facilitates the direct replacement of the flexible part 2.
[0033] like Figure 1 and Figure 2As shown, this application also includes a slide rail 10, on which at least one housing 3 is slidably disposed. Multiple housings 3 can be disposed on the slide rail 10 to adjust the flexible member 2 and the fiber cloth 1 at different positions on the coating roller, thereby accommodating coating rollers of different lengths. Preferably, the bottom of the housing 3 is provided with a slider 8 equipped with a positioning member 4. The slider 8 is slidably connected to the slide rail 10. This application provides two housings 3 on the slide rail 10. Since the ends of the coating roller are prone to overflow, the housings 3 are adjusted along the slide rail 10 to align the fiber cloth 1 with the ends of the coating roller to clean the slurry adhering to the coating roller. The housings 3 can slide directly with the slide rail 10 or slide with the slide rail 10 through the slider 8, thereby improving the stability of the movement of the housings 3. The positioning member 4 can be a pin, bolt, or elastic plate. When the slider 8 moves to the designated position, the pin, bolt, or elastic plate cooperates with the slide rail 10 to fix the position of the housing 3 in the designated position, which facilitates the positioning and cleaning of the slurry at the end of the coating roller.
[0034] like Figure 2 As shown, this application also includes a lifting device 11 for driving the housing 3 to move vertically. The lifting device 11 can drive the housing 3 to rise and fall, thereby adhering the fiber cloth 1 to the surface of the coating roller. Alternatively, the lifting device 11 can drive the slide rail 10 to rise and fall, thereby also adhering the fiber cloth 1 to the surface of the coating roller. Specifically, the lifting device 11 includes a screw threaded to the slide rail 10 and an adjusting device 9 for driving the screw to rotate. The adjusting device 9 can be a motor driven at the end of the screw, or a combination of a motor and a transmission structure. The transmission structure can be a pair of bevel gears meshing with each other to adjust the installation direction of the motor. Alternatively, a pair of spur gears can mesh to place the output shaft of the motor and the axis of the screw at different positions for easy installation. In addition, the lifting device 11 can also use a cylinder or electric cylinder to drive the entire slide rail 10 to rise and fall, or it can use a scissor fork and hydraulic cylinder to drive the slide rail 10 to rise and fall. Only the lifting part of the cylinder, electric cylinder, or scissor fork needs to be installed at the bottom of the slide rail 10 to drive the slide rail 10 to achieve the lifting operation.
[0035] like Figure 1As shown, the ends of the fiber fabric 1 can be directly fixed to the housing 3, such as by heat fusion. In one embodiment of this application, the fiber fabric 1 and the housing 3 are detachably connected. The ends of the fiber fabric 1 can be directly hung on the side of the housing 3, or they can be tightened to the side of the housing 3 with bolts. In this application, preferably, elastic members 6 are provided at both ends of the fiber fabric 1. The elastic members 6 hold the ends of the fiber fabric 1 onto the housing 3, and the elastic members 6 directly press the ends of the fiber fabric 1 tightly onto the housing 3. Specifically... The elastic element 6 is a spring plate equipped with a locking buckle 7. The locking buckle 7 can release the spring plate to facilitate the replacement of the fiber cloth 1. The spring plate holds the end of the fiber cloth 1 against the side of the housing 3. A fixing ear is also provided on the side of the housing 3 to facilitate the spring plate to press and fix the end of the fiber cloth 1. The end of the spring plate is also provided with an anti-slip pad 5. After the spring plate is locked, the anti-slip pad 5 presses the fiber cloth 1 against the side of the housing 3, effectively preventing the fiber cloth 1 from easily slipping or misaligning when wiping the coating roller.
[0036] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
