[0038] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clearly, the technical solutions of the present invention are further explained below with reference to the accompanying drawings and through specific implementation methods.

[0040] In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of the features, and are used to distinguish and describe features, without distinction of order or importance. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] Reference below Figures 1 to 9The coating machine material blocking device provided by the utility model is introduced. The coating machine material blocking device is fixedly arranged in the coating machine and can be closely fitted with the coating roller 300 and the knife roller 200 to constrain the coating in a preset shape so that the coating is coated on the current collector with a preset width.

[0043] Specifically, Figure 1 to Figure 2 As shown, the coating machine material blocking device mainly includes a pad strip 1 and an adjustment component 2. The pad strip 1 includes a first portion 11, a second portion 12 and a third portion 13. The third portion 13 is connected to the frame of the coating machine so that the entire pad strip 1 can remain fixed and always fit the coating roller 300. The first portion 11 and the second portion 12 are both connected to the third portion 13, and the first portion 11 and the second portion 12 are spaced apart to form an installation space, which can be used to install the above-mentioned adjustment component 2. The coating roller 300 is located on one side of the first portion 11, and the second portion 12 is located on the other side of the first portion 11. The first portion 11 is used to fit the outer peripheral surface of the coating roller 300, so as to scrape off part of the coating adhering to the coating roller 300, especially to scrape off the dry materials or impurities adhering to the surface of the coating roller 300, so that they are blocked by the cushion strip 1, and are not carried along with the coating roller 300 to the area of ​​the gap between the coating roller 300 and the cushion strip 1 to damage the collector. It can also further prevent impurities or dry materials from passing through the gap between the cushion strip 1 and the coating roller 300 and entering the slurry in the material tank, thereby reducing the problems of appearance particles, scratches, exposed foil, etc. during coating.

[0044] The adjusting assembly 2 is transmission-connected to the first portion 11 and the second portion 12, and the adjusting assembly 2 can adjust the distance between the first portion 11 and the second portion 12 in the direction toward the coating roller 300, thereby adjusting the distance between the first portion 11 and the coating roller 300 or the pressure applied by the first portion 11 to the coating roller 300, so that the first portion 11 can be attached to the outer peripheral surface of the coating roller 300. Exemplarily, after the cushion strip 1 is installed on the coating machine, when the first portion 11 is in a position where it cannot be attached to the coating roller 300, in order to make the cushion strip 1 and the coating roller 300 attached, the distance between the first portion 11 and the second portion 12 can be increased by the adjusting assembly 2, so that the first portion 11 moves toward the coating roller 300, so that the distance between the first portion 11 and the coating roller 300 can be reduced until the first portion 11 and the coating roller 300 are attached. When the first part 11 is in contact with the coating roller 300, but the pressure is low and the contact is not tight enough, in order to make the cushion strip 1 and the coating roller 300 closely contact, the distance between the first part 11 and the second part 12 can be increased by adjusting the component 2 so that the first part 11 moves toward the coating roller 300, so that the pressure between the first part 11 and the coating roller 300 can be increased, thereby increasing the pressure and the tightness of contact. When the pressure between the first part 11 and the coating roller 300 is too high, resulting in abnormal phenomena such as wear, the distance between the first part 11 and the second part 12 can be reduced by adjusting the component 2 so that the first part 11 moves away from the coating roller 300, thereby reducing the pressure between the first part 11 and the coating roller 300 and avoiding abnormal phenomena such as wear.

[0045] By providing the first part 11 and the second part 12 on the cushion strip 1, and providing an adjustment component 2 between the first part 11 and the second part 12 for adjusting the distance between the first part 11 and the second part 12, the distance between the first part 11 and the coating roller 300 or the pressure applied by the first part 11 to the coating roller 300 can be conveniently adjusted through the adjustment component 2, thereby ensuring that the first part 11 can be attached to the outer peripheral surface of the coating roller 300 with appropriate pressure, so that when the cushion strip 1 is worn or replaced, the tightness of the fit between the first part 11 and the coating roller 300 can still be quickly and conveniently ensured, ensuring that the coating quality is not affected by the wear of the cushion strip 1 or the replacement of the cushion strip 1, thereby ensuring the performance and quality of the battery.

[0046] like Figure 1 As shown, in this embodiment, the coating machine includes a material tank 100, which is connected to the frame of the coating machine and can accommodate the coating. The third part 13 is detachably mounted on the bottom plate of the material tank 100 by bolts to facilitate replacement and maintenance, and is conducive to setting the material blocking device on the existing coating machine at a relatively low cost.

[0047] like Figure 1 , Figure 2As shown, the first portion 11 is extended toward the side of the coating roller 300 away from the knife roller 200, and the first portion 11 and the third portion 13 form a fitting surface 10 for fitting the coating roller 300. Along the circumference direction of the coating roller 300, the fitting surface 10 can at least fit one-fourth of the circumference of the coating roller 300, thereby having better coverage of the coating on the coating roller 300, preventing the waste of coating, and maintaining a certain blocking effect in the event of local failure. Optionally, in some other embodiments, the fitting surface 10 can also be formed only on the first portion 11, and the fitting surface 10 can at least fit one-fourth of the circumference of the coating roller 300, which can also achieve better coverage and blocking effects.

[0048] More specifically, refer to Figure 2 As shown, in this embodiment, the pad strip 1 is made of a deformable material as a whole, such as polyurethane, polytetrafluoroethylene, etc., so that the second part 12 plays a certain supporting role on the adjustment component 2, and enables the first part 11 to move in the direction toward and away from the coating roller 300 under the action of the adjustment component 2, so as to adjust the distance and pressure between the first part 11 and the coating roller 300. Preferably, in this embodiment, the pad strip 1 is made of polyurethane in one piece. The polyurethane material is soft, elastic, tough, not easy to wear, has a long service life, and has better stability, chemical resistance, resilience and mechanical properties than polytetrafluoroethylene, has smaller compression deformation, and can more conveniently adjust the distance and pressure. It should be noted that regardless of whether the second part 12 moves away from the coating roller 300 under the action of the adjustment component 2, as long as the second part 12 can support the adjustment component 2 and enable the first part 11 to move toward the coating roller 300 when the distance between the first part 11 and the second part 12 increases, it belongs to the scope of protection of the utility model.

[0049] Optionally, in some embodiments, the first part 11 and the third part 13 may be rotatably connected via a rotating shaft, or movably connected via a flexible connector made of rubber or other materials, or one of the first part 11 and the third part 13 may be made of a deformable material, so that the distance and pressure between the first part 11 and the coating roller 300 can be adjusted. Therefore, the material and structure of the cushion strip 1 are not further specifically limited in the present invention, as long as the first part 11 and the third part 13 are connected in an adjustable angle, it falls within the scope of protection of the present invention.

[0050] Reference Figure 3 , Figure 4As shown, in this embodiment, the adjustment component 2 includes an elastic member 21, and the elastic member 21 can apply elastic force to the first part 11, so that the first part 11 abuts against the outer surface of the coating roller 300. The elastic member 21 is a spring, and the spring has a first end and a second end, and the distance between the first end and the second end is adjustable. The first end is transmission-connected to the first part 11, and the second end is transmission-connected to the second part 12. The spring is arranged between the first part 11 and the second part 12 in a compressed state to change the distance between the first part 11 and the second part 12. For example, when the coating roller 300 has radial runout, the elastic force of the spring can make the first part 11 always abut against the outer peripheral surface of the coating roller 300, that is, to have a suitable pressure between the first part 11 and the coating roller 300.

[0051] Reference Figure 4 As shown, the adjustment assembly 2 also includes an adjustment screw 22, the second part 12 is provided with a threaded hole, and the screw portion of the adjustment screw 22 is inserted into the threaded hole and threadedly connected to the second part 12. The spring is arranged in a compressed state, and its first end is transmission-connected to the first part 11, and the second end is transmission-connected to the second part 12 through the screw portion. When the adjustment screw 22 is rotated to make it penetrate into the first part 11 and the second part 12, the spring will be compressed and generate a greater elastic force, so that the distance between the first part 11 and the second part 12 is increased, so as to shorten the distance between the first part 11 and the coating roller 300 or increase the pressure between the first part 11 and the coating roller 300. When the adjustment screw 22 is rotated to make it away from the first part 11 and the second part 12, the deformation of the spring is reduced, and the elastic force generated by the spring is also reduced accordingly, so that the distance between the first part 11 and the second part 12 is reduced, so as to reduce the pressure between the first part 11 and the coating roller 300.

[0052] Preferably, in this embodiment, the adjustment assembly 2 further includes an anti-rotation pad 23, which is rotatably mounted on the end of the screw portion and abutted between the screw portion and the spring to prevent the spring from twisting when the adjustment screw 22 is rotated. Figure 4 , Figure 5 As shown, the anti-rotation pad 23 includes a plug-in portion 231 and a support portion 232 that are connected and arranged. The plug-in portion 231 has a plug-in hole, and the end of the screw portion can be plugged into the plug-in portion 231, and when rotating, it will slide and rub against the inner surface of the plug-in portion 231. Of course, it can be understood that the plug-in portion 231 can also have a threaded hole, and the end of the screw portion can be threadedly connected to the plug-in portion 231. As long as the connection between the screw portion and the anti-rotation pad 23 can be achieved, this embodiment is not limited here. The support portion 232 has a support surface larger than the diameter of the spring, which can fully and stably support the second end of the spring, thereby avoiding the phenomenon of bending of the spring and ensuring the stability of the fit between the first portion 11 and the coating roller 300.

[0053] Furthermore, if Figure 4 , Figure 6 As shown, the adjustment assembly 2 further includes an anti-bending limit shaft 24. One end of the anti-bending limit shaft 24 is fixedly connected to the first portion 11, and the other end of the anti-bending limit shaft 24 can abut against the anti-rotation pad 23 to limit the minimum distance between the first portion 11 and the second portion 12, that is, to limit the maximum compression of the spring, to prevent abnormal wear between the first portion 11 and the coating roller 300 due to excessive pressure. Optionally, the anti-bending limit shaft 24 is inserted into the spring, which can also prevent the spring from bending and deforming, thereby ensuring the fitting stability between the first portion 11 and the coating roller 300.

[0054] Preferably, refer to Figure 6 As shown, the end of the anti-bending limit shaft 24 connected to the first part 11 is provided with a connecting portion 241, and the diameter of the connecting portion 241 is not less than the diameter of the spring, so as to evenly transmit the elastic force to the first part 11, and improve the fit between the first part 11 and the coating roller 300. Of course, in some other embodiments, the connecting portion 241 can also be provided on the first part 11, or connected to the first part 11 or the anti-bending limit shaft 24 by various fixed connection methods such as bonding and welding, which are all within the scope of protection of the present utility model.

[0055] Further optionally, in this embodiment, if Figure 6 , Figure 7 As shown, the anti-bending limit shaft 24 includes a fixed shaft 242 and a limiting shaft 243, one end of the fixed shaft 242 abuts against the first part 11, the other end of the fixed shaft 242 is provided with a plug hole along the axial direction, one end of the limiting shaft 243 is slidably inserted in the plug hole, and the other end of the limiting shaft 243 abuts against the anti-rotation pad 23. At this time, the fixed shaft 242 and the limiting shaft 243 can also play the effect of limiting the minimum distance between the first part 11 and the second part 12, and can play the effect of preventing the spring from bending and deforming.

[0056] Of course, in some embodiments, the anti-bending limit shaft 24 may also only include the fixed shaft 242, so as to facilitate the installation and removal of the spring, which is also within the scope of protection of the present utility model.

[0057] Optionally, in some other embodiments, the spring can also provide elastic force in a stretched state. Exemplarily, the second portion 12 is provided with a through hole, and the screw portion of the adjustment screw 22 is passed through the through hole. The first portion 11 is provided with a threaded hole, and the screw portion passes through the second portion 12 and is threadedly connected to the first portion 11, and the threaded connection length between the screw portion and the first portion 11 is adjustable. Figure 8As shown, the spring is in a stretched state and is connected to the second part 12 and the nut part of the adjusting screw 22. The stretched spring will pull the nut part toward the second part 12 under the action of elastic force, and then the screw part moves synchronously through the through hole of the second part 12, and the adjusting screw 22 pushes the first part 11 to move toward the coating roller 300, so as to achieve the first part 11 abutting against the coating roller 300. Of course, the first part 11 can also be fitted with the coating roller 300 by the way of the rotating shaft and the torsion spring or the spring sheet. Therefore, the specific type of the elastic member 21 is not limited in the utility model.

[0058] like Fig. 9 As shown, in this embodiment, the pad strip 1 is arranged in a direction parallel to the axis of the coating roller 300, or at least two pad strips 1 are arranged at intervals in a direction parallel to the axis of the coating roller 300, so that the pad strip 1 and the coating roller 300 are fitted at different positions along the axis direction through the adjustment of the adjustment component 2, for example, two pad strips 1 are arranged at both ends of the coating roller 300, so that the middle part of the coating roller 300 is not fitted by the pad strip 1, while the two sides of the middle part are fitted by the pad strip 1, or three pad strips 1 are respectively arranged in the middle part and both ends of the coating roller 300, and other positions are not fitted by the pad strip 1. In this way, the specific fitting position of the pad strip 1 and the coating roller 300 can be conveniently adjusted to meet different needs in actual production.

[0059] Illustratively, in this embodiment, at least two adjustment components 2 are arranged along a direction parallel to the axis of the coating roller 300 to adjust the distance between the first part 11 and the second part 12 at different positions of the coating roller 300, respectively, so as to achieve the effect of only the two sides of the middle part of the coating roller 300 being fitted.

[0060] Furthermore, if Figure 3 As shown, at least two adjustment components 2 are arranged between the first part 11 and the second part 12 in a direction parallel to the tangent line of the outer peripheral surface of the coating roller 300. By adjusting the components 2, the first part 11 can be well fitted with the coating roller 300 along the circumferential direction. Exemplarily, when the end of the first part 11 is more worn than the middle part, the adjustment components 2 at the end of the first part 11 are adjusted separately to bend the first part 11, so that the end of the first part 11 can be kept consistent with the middle part after wear, thereby continuing to achieve a better material blocking effect.

[0061] Therefore, in this embodiment, multiple adjustment components 2 are arranged between the first part 11 and the second part 12 in a direction parallel to the axis of the coating roller 300 and in a direction parallel to the tangent of the outer peripheral surface of the coating roller 300, so that each part of the first part 11 can be individually adjusted to fit the coating roller 300, thereby ensuring the material blocking effect and coating quality.

[0062] It is understandable that the pad strip 1 can also be an integrated structure, that is, the pad strip 1 extends in a direction parallel to the axis of the coating roller 300, and at the same time extends in a direction parallel to the tangent of the outer peripheral surface of the coating roller 300, so that the fit between the first part 11 and the coating roller 300 can be adjusted individually through each part of the first part 11, thereby ensuring the material blocking effect and coating quality.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.
