Technical Field
[0001] The present application relates to the field of coating devices, and in particular to a stirring mechanism and a coating device. Background Art
[0002] During the coating production process, the coating liquid is pumped into the liquid supply tank and coated using a coating roller.
[0003] However, some coating liquids contain micron or nanometer particles (hereinafter referred to as particles), which are prone to sedimentation during the coating process and deposited at the bottom of the liquid supply tank. The coating liquid is usually required to be sanitary, so the existing stirring device cannot stir it. Even if it can be stirred, the stirring effect will be poor, resulting in particle deposition or interference with the operation of the coating roller. Utility Model Content
[0004] The purpose of the embodiments of the present application is to provide a stirring mechanism and a coating device, which can effectively stir the coating liquid in the liquid tank without affecting the quality of the coating liquid in the liquid tank, alleviate or avoid particle deposition, and has a compact structure and does not interfere with the coating roller, etc.
[0005] In a first aspect, an embodiment of the present application provides a stirring mechanism, which includes a liquid material tank, a stirring member, and a magnetic adsorption member.
[0006] The liquid material tank extends along a first direction, and the material of the liquid material tank is a non-magnetic material; the stirring member is slidably arranged in the liquid material tank along the first direction, and the material of the stirring member is stainless iron; the magnetic adsorption member is arranged outside the liquid material tank, and the magnetic adsorption member is configured to reciprocate along the first direction to synchronously drive the stirring member to reciprocate in the liquid material tank for stirring.
[0007] In the above implementation process, a magnetic adsorption member is arranged outside the liquid material tank, and a stirring member is arranged inside the liquid material tank, and the stirring member is made of stainless iron. On the one hand, the magnetic adsorption member is used to magnetically adsorb the stirring member, so that the magnetic adsorption member moves back and forth along the first direction while synchronously driving the stirring member to move back and forth in the liquid material tank, thereby achieving stirring of the liquid in the liquid material tank, avoiding particle deposition, making it evenly distributed in the coating liquid, and improving the yield of the film layer formed by coating. On the other hand, since the two realize transmission through magnetic adsorption, the heat generated by the movement of the stirring member and the introduction of impurities can be effectively reduced, avoiding contamination of the coating liquid in the liquid material tank or causing changes in its performance, reducing or avoiding affecting the quality of the coating liquid in the liquid material tank, and at the same time, the structure is compact, and does not interfere with the coating roller during the actual coating process.
[0008] In a possible implementation manner, the stirring element is laid on the inner side of the bottom wall of the liquid material tank.
[0009] In the above implementation process, the above arrangement is simple and has high space utilization, which is conducive to stirring the bottom of the coating liquid to avoid particle deposition.
[0010] In a possible embodiment, the stirring member is plate-shaped, and has a bottom surface that fits the inner side of the bottom wall of the liquid tank.
[0011] In the above implementation process, the plate-shaped setting is not only conducive to rinsing the stirring element after stirring is completed to avoid particles from depositing on the surface of the stirring element, but the plate-shaped setting is also conducive to the stirring element to have both light weight and large area, thereby increasing the adsorption area with the magnetic adsorption element, and facilitating the magnetic adsorption element to synchronously drive the stirring element to move back and forth in the liquid material tank. The bottom surface setting is also conducive to improving the stirring effect and avoiding the formation of dead corners for particle deposition.
[0012] In a possible implementation, the width of the stirring member in the second direction is ≤ the width of the liquid tank in the second direction, the difference between the width of the stirring member in the second direction and the width of the liquid tank in the second direction is ≤ 2 cm, and the second direction is perpendicular to the first direction.
[0013] In the above implementation process, by utilizing the width limitation, on the one hand, the stirring element can be smoothly slidably disposed in the liquid material tank along the first direction; on the other hand, due to the small width difference, the generation of particle deposition dead corners can be reduced during movement, thereby improving the stirring effect.
[0014] In a possible implementation, the magnetic adsorption component is located outside the bottom wall of the liquid tank.
[0015] In the above implementation process, the magnetic adsorption component is located outside the bottom wall of the liquid material tank rather than in other positions, so that the overall structure of the stirring mechanism is compact and the space utilization rate at the bottom of the liquid material tank is improved.
[0016] In a possible embodiment, the stirring mechanism includes a screw and a screw nut installed on the screw. The screw extends along a first direction, is axially stationary and circumferentially rotatably arranged on the outer side of the bottom wall of the liquid tank, and the screw nut is connected to the magnetic adsorption component.
[0017] In the above implementation process, the magnetic adsorption component is smoothly moved back and forth along the first direction through the screw structure, thereby improving the stirring stability.
[0018] In a possible embodiment, the stirring mechanism further includes a driving assembly, which is drivingly connected to the screw to drive the screw to rotate forward and reverse.
[0019] In the above implementation process, the driving assembly drives the screw rod to rotate forward and reverse, so that the magnetic adsorption component can move back and forth smoothly along the first direction, thereby improving the stirring efficiency and realizing automatic stirring operation.
[0020] In a possible embodiment, the liquid material tank includes a coating liquid inlet and a baffle, at least a portion of the baffle is perpendicular to the axis of the coating liquid inlet, and the baffle is used to disperse the coating liquid entering from the coating liquid inlet.
[0021] In the above implementation process, the baffle is provided to disperse the coating liquid, prevent splashing, and avoid wasting the coating liquid or causing other adverse effects.
[0022] In a possible embodiment, the baffle includes, from top to bottom, a vertical section extending vertically along a third direction, an inclined section, and a horizontal section extending horizontally along a second direction, the vertical section is spaced apart from the side wall of the liquid material tank, the horizontal section is spaced apart from the bottom wall of the liquid material tank, the horizontal section extends toward the side away from the coating liquid inlet, and the first direction, the second direction and the third direction are perpendicular to each other.
[0023] In the above implementation process, the flow dispersion and drainage effects are effectively improved by improving the baffle structure.
[0024] In a second aspect, an embodiment of the present application provides a coating device, which includes the stirring mechanism and a coating roller provided in the above-mentioned embodiments. The coating roller extends along a first direction and is configured to be rotatably disposed above a liquid material tank and partially extend into the liquid material tank.

[0037] See also Figures 1 to 3 The present application provides a coating device 1000 , which includes a stirring mechanism 10 and a coating roller 20 .
[0038] See also Figure 1 as well as Figure 2 The stirring mechanism 10 includes a liquid material tank 100 , a stirring member 110 and a magnetic adsorption member 120 .
[0039] The liquid tank 100 extends along the first direction X, and the material of the liquid tank 100 is a non-magnetic material; the stirring member 110 is slidably arranged in the liquid tank 100 along the first direction X, and the material of the stirring member 110 is stainless iron; the magnetic adsorption member 120 is arranged outside the liquid tank 100, and the magnetic adsorption member 120 is configured to reciprocate along the first direction X to synchronously drive the stirring member 110 to reciprocate in the liquid tank 100 for stirring.
[0040] The liquid tank 100 is used to contain the coating liquid.
[0041] It is understandable that, since the stirring member 110 is made of stainless steel, the magnetic adsorption member 120 can magnetically adsorb the stirring member 110, thereby realizing that the magnetic adsorption member 120 synchronously drives the stirring member 110 to reciprocate in the liquid tank 100 for stirring. Since the liquid tank 100 is made of non-magnetic material, it will not interfere with the magnetic adsorption member 120 adsorbing the stirring member 110.
[0042] The magnetic adsorption member 120 may be a permanent magnet, including but not limited to a ferrite magnet, a neodymium iron boron magnet, an aluminum nickel cobalt magnet or a samarium cobalt magnet, etc. In order to improve the direct adsorption capacity of the two, the magnetic adsorption capacity between the magnetic adsorption member 120 and the stirring member 110 is as strong as possible. For example, the magnetic adsorption member 120 is a neodymium iron boron magnet. Those skilled in the art can choose according to actual needs, and no limitation is made here.
[0043] The stirring mechanism 10 provided in the present application is arranged outside the liquid tank 100 by using a magnetic adsorption member 120, and the stirring member 110 is located in the liquid tank 100, and the material of the stirring member 110 is stainless iron. On the one hand, the stirring member 110 is magnetically adsorbed by the magnetic adsorption member 120, so that the magnetic adsorption member 120 moves back and forth along the first direction X and simultaneously drives the stirring member 110 to move back and forth in the liquid tank 100, thereby achieving the stirring of the liquid in the liquid tank 100, avoiding the deposition of particles, making them evenly distributed in the coating liquid, and improving the yield of the film layer formed by coating. On the other hand, since the two realize transmission by magnetic adsorption, the heat generated by the movement of the stirring member 110 and the introduction of impurities can be effectively reduced, avoiding contamination of the coating liquid in the liquid tank 100 or causing changes in its performance, reducing or avoiding affecting the quality of the coating liquid in the liquid tank 100, and at the same time, the structure is compact, and does not interfere with the coating roller 20 and the like during the actual coating process.
[0044] like Figure 1 as well as Figure 2 As shown, the stirring member 110 is laid on the inner side of the bottom wall 101 of the liquid tank 100 .
[0045] The inner side of the bottom wall 101 refers to the side of the bottom wall 101 facing the inside of the liquid tank 100 .
[0046] The above arrangement improves space utilization and helps to stir the bottom of the coating liquid to avoid particle deposition.
[0047] The stirring member 110 may be in a rod shape, a plate shape, a wave shape or an irregular shape.
[0048] like Figure 2 As shown, the stirring member 110 has a relative top surface 111 and a bottom surface 112, wherein the bottom surface 112 can be in contact with the inner side of the bottom wall 101 of the liquid tank 100, and the top surface 111 can be a flat surface, a wavy surface or a curved surface, etc., and technical personnel in this field can choose according to actual needs.
[0049] In this embodiment, the stirring member 110 is plate-shaped and has a bottom surface 112 that is in contact with the inner side of the bottom wall 101 of the liquid tank 100 .
[0050] The plate-shaped setting is not only conducive to rinsing the stirring element 110 after stirring is completed to avoid particles from depositing on the surface of the stirring element 110, but the plate-shaped setting is also conducive to the stirring element 110 to have a lighter weight and a larger area, thereby increasing the adsorption area with the magnetic adsorption element 120, and facilitating the magnetic adsorption element 120 to synchronously drive the stirring element 110 to move back and forth in the liquid tank 100. The setting of the bottom surface 112 is also conducive to improving the stirring effect and avoiding the formation of dead corners for particle deposition.
[0051] like Figure 1 As shown, the inner side of the bottom wall 101 of the liquid tank 100 is a plane, and the top surface 111 of the stirring member 110 is parallel to the bottom surface 112 and both are planes.
[0052] Optionally, when the stirring member 110 is plate-shaped, the top surfaces 111 of the stirring member 110 at both ends along the first direction X may be provided with external chamfers, or as shown in FIG. Figure 2 As shown, the top surfaces 111 at both ends of the stirring member 110 along the first direction X and the connection between the two side surfaces of the stirring member 110 in the first direction are smoothly transitioned, which is conducive to the stable and smooth movement of the stirring member 110 along the first direction X.
[0053] The width of the stirring member 110 in the second direction Y is ≤ the width of the liquid tank 100 in the second direction Y, the difference between the width of the stirring member 110 in the second direction Y and the width of the liquid tank 100 in the second direction Y is ≤ 2 cm, and the second direction Y is perpendicular to the first direction X.
[0054] By limiting the width, on the one hand, the stirring member 110 can be smoothly slidably disposed in the liquid tank 100 along the first direction X, and on the other hand, due to the small width difference, the generation of particle deposition dead angles can be reduced during the movement, thereby improving the stirring effect.
[0055] The magnetic attraction member 120 is located outside the bottom wall 101 of the liquid tank 100 .
[0056] The magnetic adsorption component 120 is located outside the bottom wall 101 of the liquid tank 100 instead of other positions, so that the structure is compact and the space utilization rate at the bottom of the liquid tank 100 is improved.
[0057] There are many ways to configure the magnetic adsorption component 120 to reciprocate along the first direction X. For example, a guide rail or guide groove extending along the first direction X is provided on the outer side of the bottom wall 101 of the liquid tank 100, and the magnetic adsorption component 120 is slidably embedded in the guide groove or installed on the guide rail along the first direction X.
[0058] like Figure 2 as well as Figure 3 As shown, the stirring mechanism 10 includes a screw 131 and a screw nut installed on the screw 131. The screw 131 extends along the first direction X. The screw 131 is axially fixed and circumferentially rotatable on the outside of the bottom wall 101 of the liquid tank 100. The screw nut is connected to the magnetic adsorption component 120.
[0059] The screw rod 131 structure enables the magnetic adsorption member 120 to move back and forth smoothly along the first direction X, thereby improving the stirring stability.
[0060] like Figure 2 as well as Figure 3 As shown, the stirring mechanism 10 further includes a driving assembly 140 , which is transmission-connected to the screw rod 131 to drive the screw rod 131 to rotate forward and reverse.
[0061] In the above implementation process, the driving assembly 140 drives the screw rod 131 to rotate forward and reverse, so that the magnetic adsorption component 120 can move back and forth smoothly along the first direction X, thereby improving the stirring efficiency and realizing automatic stirring operation.
[0062] The driving component 140 is, for example, a servo motor, the base of which is fixed on the liquid tank 100, and the rotating shaft of the servo motor can be coaxially connected to the screw rod 131 or connected with a belt drive, thereby driving the screw rod 131 to rotate forward and reverse, thereby realizing the reciprocating and smooth movement of the magnetic adsorption component 120 along the first direction X.
[0063] like Figure 1 As shown, the liquid tank 100 includes a coating liquid inlet 150 and a baffle 160 , at least a portion of the baffle 160 is perpendicular to the axis of the coating liquid inlet 150 , and the baffle 160 is used to disperse the coating liquid entering from the coating liquid inlet 150 .
[0064] The baffle 160 is provided to disperse the coating liquid, prevent splashing, and avoid wasting the coating liquid or causing other adverse effects.
[0065] Please continue reading Figure 1 The baffle 160 includes, from top to bottom, a vertical section 161 extending vertically along the third direction Z, an inclined section 162, and a horizontal section 163 extending horizontally along the second direction Y. The vertical section 161 is spaced apart from the side wall of the liquid material tank 100, the horizontal section 163 is spaced apart from the bottom wall 101 of the liquid material tank 100, and the horizontal section 163 extends toward a side away from the coating liquid inlet 150. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.
[0066] The flow dispersion and drainage effects are effectively improved by improving the structure of the baffle 160 .
[0067] The coating roller 20 extends along the first direction X. The coating roller 20 is configured to be rotatably disposed above the liquid tank 100 and partially extend into the liquid tank 100. The coating roller 20 is, for example, a micro-concave roller. The coating roller 20 is used to apply the coating liquid to the base film by rotating.
[0068] It should be noted that the coating roller 20 is located above the horizontal plane where the horizontal section 163 of the baffle 160 is located, and the stirring member 110 is located below the horizontal plane where the horizontal section 163 of the baffle 160 is located. This arrangement can effectively avoid interference between the stirring member 110 and the coating roller 20 during the stirring process.
[0069] See also Figures 1 to 3 , the use process of the coating device 1000 provided in this application is:
[0070] The coating liquid enters the liquid supply tank from the coating liquid inlet 150, flows through the baffle 160 from bottom to top to fill the liquid supply tank, and the coating roller 20 rotates to apply the coating liquid to the base film, and the driving component 140 drives the screw 131 to move back and forth in the first direction X to drive the magnetic adsorption component 120. The magnetic adsorption component 120 drives the stirring component 110 made of stainless steel to reciprocate in the first direction X in the liquid supply tank through magnetic force to stir and lift up the settled particles.
[0071] The stirring mechanism provided in the present application can effectively stir the coating liquid in the liquid tank without affecting the quality of the coating liquid in the liquid tank, alleviate or avoid particle deposition, make it evenly distributed in the coating liquid, and improve the yield of the film layer formed by the coating device.
[0072] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
