Description

Technical Field

[0001] The utility model relates to the field of coating, and particularly relates to a double-sided coating device. Background Art

[0002] The double-sided coating device includes two coating dies arranged oppositely, and the material passes between the two coating dies. Each coating die coats the corresponding end face of the material to achieve double-sided coating of the material. However, in the related art, the double-sided coating device occupies a large space, and the coating effect of the material is poor. Summary of the Utility Model

[0003] The utility model is made based on the inventor's discovery and recognition of the following facts and problems:

[0004] The inventor found that in the double-sided coating device of the related art, two coating dies arranged oppositely are spaced along the moving direction of the material. During the coating operation, one coating die coats one end face of the material first, and then the other coating die coats the other end face of the material. However, after one end face is coated, the material has a slight shake, which will cause the distance between the other coating die and the other end face to fluctuate, affecting the coating effect of the other end face. At the same time, after one end face is coated, the thickness and humidity of the material will change. Therefore, when the two end faces are coated separately, there are also differences in the thickness and humidity of the material, resulting in differences in the coating effects of the two end faces, and thus the double-sided coating effect of the material is poor. In addition, the fact that the two coating dies are spaced along the moving direction of the material also leads to a large occupied space.

[0005] The utility model aims to solve at least one of the technical problems in the related art to some extent. For this purpose, an embodiment of the utility model provides a double-sided coating device, which has a better coating effect and occupies a smaller space.

[0006] The double-sided coating device according to the embodiment of the utility model includes a first coating die and a second coating die. The coating outlets of the first coating die and the second coating die are arranged oppositely, and the first coating die and the second coating die are spaced along the direction of the opposite arrangement, so that the material moves through between the first coating die and the second coating die. The center line of the coating outlet of the first coating die and the center line of the coating outlet of the second coating die are located in the same virtual plane.

[0007] The centerlines of the coating outlets of the first coating die head and the second coating die head of the double-sided coating device according to the embodiments of the present utility model are located in the same virtual plane, so that the first coating die head and the second coating die head can simultaneously coat two end faces of the same position of the material. The impact force of the first coating die head on the material is offset by the impact force of the second coating die head on the material, and the thickness and humidity of the two end faces of the material are the same when being coated, so that a better coating effect can be obtained, and at the same time, the double-sided coating device has a smaller occupied space.

[0023] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0024] Below, refer to Figures 1-3 to describe a double-sided coating device according to an embodiment of the present invention.

[0025] As Figures 1-3 shown, the double-sided coating device according to the embodiment of the present invention includes a first coating die head 1 and a second coating die head 2.

[0026] The coating outlets of the first coating die head 1 and the second coating die head 2 are arranged oppositely, and the first coating die head 1 and the second coating die head 2 are arranged at intervals along the oppositely arranged direction, so that the material 3 moves through between the first coating die head 1 and the second coating die head 2. The center line of the coating outlet of the first coating die head 1 and the center line of the coating outlet of the second coating die head 2 are located in the same virtual plane.

[0027] Specifically, as Figure 1 and Figure 2 shown, the first coating die head 1 and the second coating die head 2 are arranged at intervals in the left-right direction, and the material 3 moves from top to bottom and passes between the first coating die head 1 and the second coating die head 2. Preferably, a guide roller 14 is provided above the first coating die head 1 and the second coating die head 2. The material 3 first moves in the left-right direction, then abuts against the outer peripheral surface of the guide roller 14, and under the guidance of the outer peripheral surface of the guide roller 14, it becomes to move from top to bottom and then passes between the first coating die head 1 and the second coating die head 2.

[0028] The coating outlet of the first coating die head 1 is arranged to the right, and the coating outlet of the second coating die head 2 is arranged to the left, so that the coating outlets of the first coating die head 1 and the second coating die head 2 are arranged oppositely in the left-right direction.

[0029] The center line of the coating outlet of the first coating die head 1 and the center line of the coating outlet of the second coating die head 2 are located in the same virtual plane. Specifically, the center line of the coating outlet of the first coating die head 1 extends in the left-right direction, and the center line of the coating outlet of the second coating die head 2 also extends in the left-right direction. The coating outlet of the first coating die head 1 and the coating outlet of the second coating die head 2 are located at the same height position to form a horizontally arranged virtual plane. In other words, the virtual plane is a horizontal plane.

[0030] When the material 3 passes between the first coating die head 1 and the second coating die head 2, the first coating die head 1 coats the left end face of the material 3, and the second coating die head 2 coats the right end face of the material 3. The coating position of the first coating die head 1 on the material 3 and the coating position of the second coating die head 2 on the material 3 are at the same height. Therefore, the impact force of the first coating die head 1 on coating the material 3 cancels out the impact force of the second coating die head 2 on coating the material 3, and the material 3 will not shake. At the same time, when the left and right end faces of the material 3 are coated, the thickness and humidity of the material 3 faced by the first coating die head 1 and the second coating die head 2 are consistent, thereby avoiding the problem of poor coating effect caused by sequential coating in the related art. Moreover, the first coating die head 1 and the second coating die head 2 being located at the same height position can also make the occupied space of the double-sided coating device smaller, so as to be applicable to more environmental spaces and improve the compactness of the production line.

[0031] Preferably, both the first coating die head 1 and the second coating die head 2 are slit die heads.

[0032] In the double-sided coating device according to the embodiment of the present invention, the center line of the coating outlet of the first coating die head and the center line of the coating outlet of the second coating die head are located in the same virtual plane, so that the first coating die head and the second coating die head can simultaneously coat the two end faces of the same position of the material. The impact force of the first coating die head on coating the material cancels out the impact force of the second coating die head on coating the material, and the thickness and humidity of the two end faces of the material are consistent when being coated, thereby being able to obtain a better coating effect and at the same time making the double-sided coating device have a smaller occupied space.

[0033] In some embodiments, the virtual plane is orthogonal to the moving direction of the material 3.

[0034] As Figure 1 and Figure 2 shown, the material 3 moves from top to bottom and passes between the first coating die head 1 and the second coating die head 2. The virtual plane is a horizontal plane. Therefore, the virtual plane is orthogonal to the moving direction of the material 3 to ensure that the coating position of the first coating die head 1 on the material 3 and the coating position of the second coating die head 2 on the material 3 are at the same height and on the two end faces of the material 3, thereby ensuring the coating effect.

[0035] In some embodiments, the double-sided coating device of the embodiment of the present utility model further includes a base 4. The base 4 is provided with a channel 41 that penetrates the base 4 along the moving direction of the material 3. The channel 41 is used for the material 3 to move through. The base 4 is provided with a first coating die head 1 and a second coating die head 2. The first coating die head 1 is located on one side of the channel 41 along the relatively arranged direction, and the second coating die head 2 is located on the other side of the channel 41 along the relatively arranged direction.

[0036] As Figure 1 and Figure 2 shown, the base 4 is horizontally arranged. The base 4 is provided with a channel 41 that penetrates the base 4 along the vertical direction. The channel 41 extends in a strip shape along the front-rear direction for the material 3 to pass through from top to bottom. The left end of the top surface of the base 4 is provided with the first coating die head 1, and the right end of the top surface of the base 4 is provided with the second coating die head 2. The channel 41 is located between the first coating die head 1 and the second coating die head 2. By installing the first coating die head 1 and the second coating die head 2 on the base 4, it is ensured that the first coating die head 1 and the second coating die head 2 are located at the same height position, and further ensured that the coating outlets of the first coating die head 1 and the second coating die head 2 are located at the same height position.

[0037] In some embodiments, both the first coating die head 1 and the second coating die head 2 are movable relative to the base 4 along the relatively arranged direction.

[0038] As Figure 1 and Figure 2 shown, the first coating die head 1 is movable relative to the base 4 along the left-right direction to adjust the distance between the first coating die head 1 and the material 3. The second coating die head 2 is movable relative to the base 4 along the left-right direction to adjust the distance between the second coating die head 2 and the material 3. Thus, the double-sided coating device can be applicable to the coating of various materials 3.

[0039] In some embodiments, the double-sided coating device of the embodiment of the present utility model further includes a limiting component 5. The limiting component 5 is arranged on the base 4. The limiting component 5 is connected to at least one of the first coating die head 1 and the second coating die head 2 to limit the position of at least one of the first coating die head 1 and the second coating die head 2 relative to the base 4 along the relatively arranged direction. Both the first coating die head 1 and the second coating die head 2 are connected to the corresponding limiting component 5.

[0040] As Figures 1-3As shown, the base 4 is provided with a limiting component 5. The limiting component 5 can be connected to the first coating die head 1 and the second coating die head 2 simultaneously, or can be only connected to the first coating die head 1 or the second coating die head 2. However, both the first coating die head 1 and the second coating die head 2 are connected with corresponding limiting components 5. It should be noted that when the limiting component 5 can be connected to the first coating die head 1 and the second coating die head 2 simultaneously, the corresponding limiting components 5 connected to the first coating die head 1 and the second coating die head 2 can be the same limiting component 5. When the limiting component 5 is only connected to the first coating die head 1 or the second coating die head 2, the corresponding limiting components 5 connected to the first coating die head 1 and the second coating die head 2 are different limiting components 5.

[0041] The limiting component 5 is used to limit the positions of the connected first coating die head 1 and / or the second coating die head 2 relative to the base 4 in the left-right direction, thereby limiting the distance between the first coating die head 1 and / or the second coating die head 2 and the material 3.

[0042] Preferably, the distances between the first coating die head 1 and the second coating die head 2 and the material 3 are the same.

[0043] In some embodiments, the limiting component 5 is provided on at least one side in the extending direction of the channel 41. The extending direction of the channel 41 is orthogonal to the opposite setting direction and the moving direction of the material 3. The limiting component 5 is connected to both the first coating die head 1 and the second coating die head 2, and can respectively limit the positions of the first coating die head 1 and the second coating die head 2 relative to the base 4 in the opposite setting direction.

[0044] As Figures 1-3 shown, both the first coating die head 1 and the second coating die head 2 are strip-shaped extending in the front-rear direction. The limiting component 5 is connected to the first coating die head 1 and the second coating die head 2 simultaneously. The limiting components 5 are provided on both the front side and the rear side of the base 4 to avoid interference with the material.

[0045] The limiting component 5 on the front side is connected to the front end of the first coating die head 1 and the front end of the second coating die head 2 simultaneously. The limiting component 5 on the rear side is connected to the rear end of the first coating die head 1 and the rear end of the second coating die head 2 simultaneously. By the limiting components 5 on the front side and the rear side, it is ensured that the distance between the first coating die head 1 and the material 3 is constant in the front-rear direction, and the distance between the second coating die head 2 and the material 3 is constant in the front-rear direction, avoiding the change of the distance between the first coating die head 1 and the second coating die head 2 and the material 3 caused by the inclination of the first coating die head 1 and the second coating die head 2.

[0046] In some embodiments, the limit component 5 includes a limit support 51 and a limit adjuster 52. The limit support 51 is provided on the base 4 and is located in the extending direction of the channel 41. Limit adjusters 52 are provided on both sides of the limit support 51 along the relatively arranged direction. The limit adjuster 52 is movable relative to the limit support 51 along the relatively arranged direction. One side of the limit adjuster 52 is connected to the first coating die head 1, and the other side of the limit adjuster 52 is connected to the second coating die head 2.

[0047] As Figures 1-3 shown, the limit component 5 includes a limit support 51 and a limit adjuster 52. The limit support 51 is provided on the top surface of the base 4, and corresponding limit supports 51 are provided on the front side and the rear side of the channel 41.

[0048] Corresponding limit adjusters 52 are provided at both the left and right ends of the limit support 51. The limit adjuster 52 extends in the left-right direction and is movable relative to the limit support 51 along the left-right direction.

[0049] The left end of the left-end limit adjuster 52 abuts against the first coating die head 1 to limit the position of the first coating die head 1 relative to the base 4 in the left-right direction by abutting against the first coating die head 1, thereby limiting the distance between the first coating die head 1 and the material 3.

[0050] The right end of the right-end limit adjuster 52 abuts against the second coating die head 2 to limit the position of the second coating die head 2 relative to the base 4 in the right-left direction by abutting against the second coating die head 2, thereby limiting the distance between the second coating die head 2 and the material 3.

[0051] Preferably, the limit adjuster 52 is threadedly connected to the limit support 51 to enable the limit adjuster 52 to move relative to the limit support 51 along the left-right direction.

The first coating die head 1 is provided on the two sliding components 6 on the left side, so that the first coating die head 1 can slide relative to the base 4 in the left - right direction. The second coating die head 2 is provided on the two sliding components 6 on the right side, so that the second coating die head 2 can slide relative to the base 4 in the left - right direction. The sliding component 6 is preferably a linear module.

[0054] At least two driving components 7 are further provided on the base 4. Corresponding driving components 7 are provided on both the left and right sides of the channel 41. Preferably, two corresponding driving components 7 are provided on both the left and right sides of the channel 41.

The at least two die head supports 9 provided on the same carrier plate 8 are connected to the corresponding first coating die head 1 or the corresponding second coating die head 2. The arrangement direction of the at least two sliding components 6 on the same side is the same as the arrangement direction of the at least two die head supports 9 on the same carrier plate 8, and both are orthogonal to the relatively - arranged direction and the moving direction of the material 3.

[0057] As Figures 1-3As shown in the figure, corresponding carrier plates 8 are respectively provided on the left and right sides of the channel 41.
