Description

Technical Field

[0001] The utility model relates to the technical field of coated aluminum foil, and particularly relates to a device for adjusting the dyn value of coated aluminum foil. Background Art

[0002] During the aluminum foil coating process, the dyn value is an important parameter, which reflects the surface tension or wettability of the material. The aluminum foil with a higher dyn value has a greater surface tension, can better attract and hold the coating, thus contributing to the uniformity of coating. If the dyn value of the aluminum foil surface is lower, it may lead to uneven distribution of the coating, forming spots or stripes. Moreover, for the purchased raw material aluminum foil, the higher the dyn value of its surface, the higher the price.

[0003] During the surface carbon coating process of aluminum foil, according to customer requirements, some aluminum foils need to be coated with ceramic coatings on both sides of the carbon-coated aluminum foil. To improve the coating effect of the ceramic coating on the aluminum foil surface and reduce the use cost, the prior art generally uses alcohol solution to be applied on the aluminum foil surface first to increase the dyn value of the surface of the aluminum foil coated with the ceramic coating. However, in the prior art, a brush dipped in alcohol solution is generally used to apply the specified aluminum foil surface. This manual application method of alcohol is relatively troublesome and has a large workload, which is not suitable for long-term application work; moreover, the brush will be contaminated by the aluminum foil surface. If the contaminated brush cannot be cleaned in time, it will affect the uniformity of the subsequent coating on the aluminum foil. Summary of the Utility Model

[0004] To solve the technical problems existing in the above background art, the utility model provides a device for adjusting the dyn value of coated aluminum foil.

[0005] The technical solution of the utility model is as follows:

[0006] A device for adjusting the dyn value of coated aluminum foil is arranged on an aluminum foil unwinding mechanism. The aluminum foil unwinding mechanism has an unwinding roller, and includes a first aluminum foil wiping mechanism arranged on the front or back of the aluminum foil. A single first aluminum foil wiping mechanism includes a guide shaft, and a fabric winding and unwinding mechanism and an alcohol drip tank arranged on the guide shaft. The guide shaft is arranged on one side of the unwinding roller, and its axis is parallel to the axis of the unwinding roller;

[0007] The fabric winding and unwinding mechanism includes a winding wheel set, an unwinding wheel set, and a first fabric wound around the winding wheel set and the unwinding wheel set. The first fabric is tightly arranged on the front or back of the aluminum foil, and its unwinding direction is opposite to the aluminum foil unwinding direction;

[0008] The alcohol drip tank is arranged on one side of the fabric and can convey alcohol solution to the first fabric;

[0009] The outer side of the first fabric is tightly attached to the front or back of the aluminum foil.

[0010] Install the first aluminum foil wiping mechanism on one side of the front or back of the carbonized aluminum foil. Wipe the front or back of the aluminum foil with the first cloth with alcohol solution. The first cloth is unwound and wound through the winding wheel set and the unwinding wheel set. The first cloth that contacts and applies alcohol to the surface of the aluminum foil will leave impurities after contacting the surface of the aluminum foil. The used first cloth is wound by the winding wheel set, so that the surface of the aluminum foil is always in contact with the clean cloth with alcohol solution, reducing the influence of impurities on the first cloth on the subsequent coating of ceramics or other coatings on the aluminum foil.

[0011] The structure that the above-mentioned winding wheel set and unwinding wheel set can move on the guide shaft is that the cloth winding and unwinding mechanism further includes a mounting seat. The guide shaft is passed through the mounting seat, and the mounting seat can move along the axis of the guide shaft. The winding wheel set and the unwinding wheel set are arranged on the mounting seat.

[0012] To facilitate adjusting the tightness of the cloth between the winding wheel set and the unwinding wheel set and to facilitate adjusting the better contact between the cloth and the surface of the aluminum foil, there is also an adjusting roller parallel to its axis on one side of the unwinding roller. Both ends of the adjusting roller are connected to the housing of the aluminum foil unwinding mechanism. The inner side of the first cloth is slidably connected to the adjusting roller. The gap between the adjusting roller and the unwinding roller can accommodate the aluminum foil and the first cloth.

[0013] Regarding the setting position of the alcohol drip irrigation, it is convenient to put the alcohol solution in it on the cloth. The alcohol drip irrigation is arranged on one side of the mounting seat close to the adjusting roller, and the liquid outlet of the alcohol drip irrigation is inclined downward towards the inner side of the first cloth.

[0014] The specific structure of the above-mentioned alcohol drip irrigation is that the alcohol drip irrigation includes a tank body and a liquid outlet head connected in communication. The tank body is connected to the external alcohol solution through a hose. The liquid outlet head is arranged close to the adjusting roller, and the liquid outlet of the liquid outlet head is arranged close to the inner side of the first cloth at the lower position.

[0015] Regarding the mounting seat that can slide along its axis on the guide shaft for applying to the surfaces of aluminum foils at different positions and will not rotate on the guide shaft, a non-circular through hole is opened in the mounting seat. The guide shaft is passed through the non-circular through hole and is connected to the mounting seat through a tightening mechanism.

[0016] The specific structure of the above-mentioned tightening mechanism is that the tightening mechanism includes a tightening member and a tightening plate located in the non-circular through hole. The tightening member can pass through the mounting seat to tighten the tightening plate against the outer surface of the guide shaft.

[0017] In order to be able to apply alcohol to both the front and back sides of the aluminum foil simultaneously, improve the surface tension values of both sides of the aluminum foil, and enhance the effect of uniformly applying the coating on the surface of the aluminum foil, a second aluminum foil wiping mechanism is provided on the back or front side of the aluminum foil. The second aluminum foil wiping mechanism has the same structure as the first aluminum foil wiping mechanism and is respectively arranged on both sides perpendicular to the width direction of the aluminum foil. The second cloth of the second aluminum foil wiping mechanism is closely attached to the back or front side of the aluminum foil.

[0018] The beneficial effects of the present utility model are as follows;

[0019] The first aluminum foil wiping mechanism is arranged on one side of the aluminum foil unwinding mechanism. After applying carbon to the middle of the aluminum foil, when other coatings need to be applied to both sides of the aluminum foil, the first cloth winding and unwinding mechanism drives the first cloth to move on the surface of the aluminum foil and in the opposite direction of the aluminum foil, and the alcohol solution is put onto the first cloth through the liquid outlet of the alcohol drip irrigation. Then, the part of the aluminum foil that needs to increase the surface tension value is coated with alcohol by the first cloth with the alcohol solution, and the cloth after contacting the surface of the aluminum foil is collected to avoid the first cloth with impurities contacting the surface of the aluminum foil and affecting the cleanliness of the aluminum foil surface;

[0020] By providing a second aluminum foil wiping mechanism on the other surface of the aluminum foil, cooperating with the first aluminum foil wiping mechanism to apply alcohol to both sides of the aluminum foil simultaneously, the surface tension value of the aluminum foil is increased, facilitating the uniform coating of the coatings on both sides of the front and back of the aluminum foil;

[0021] The cloth winding and unwinding mechanism can move along the length direction of the guide roller and is fixedly connected to the guide roller through the pressing mechanism, facilitating the adjustment of the contact surface position between the cloth and the surface of the aluminum foil. After adjusting the position, the mounting seat is fixed on the guide roller through the pressing mechanism. Description of the Drawings

[0032] See Figure 1 and Figure 2 As shown in

[0033] See Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown in

[0034] See Figure 6As shown, the specific structure of the above-mentioned tightening mechanism is that the tightening mechanism includes a tightening member 5 and a tightening plate 6 located in the non-circular through-hole 81. The tightening member 5 can pass through the mounting seat 8 to press the tightening plate 6 against the outer surface of the guide shaft 21. One end of the tightening member 5 close to the tightening plate 6 is rotatably connected to the tightening plate 6. This connection method is a prior art. The tightening member 5 is threadedly connected to the mounting seat 8, so that when the tightening member 5 is tightened, it can drive the tightening plate 6 to press against the guide shaft 21, and when loosened, it can drive the tightening plate 6 to disengage from the guide shaft 21. Moreover, when the tightening member 5 rotates, it will not drive the tightening plate 6 to rotate.

[0035] See Figure 5 and Figure 7 As shown, the winding wheel set 22 includes winding wheels. One side of the winding wheel is connected with a first driving motor 24, and the first driving motor 24 can drive the winding wheel to rotate. The unwinding wheel set 23 includes unwinding wheels. One side of the unwinding wheel is connected with a second driving motor 25. The first fabric 3 is connected to the winding wheel and the unwinding wheel. The second driving motor 25 cooperates with the first driving motor 24 to unwind and wind the first fabric 3 on the winding wheel and the unwinding wheel. The rotational speeds of the first driving motor 24 and the second driving motor 25 are adjustable. The first driving motor 24 and the second driving motor 25 are respectively installed on the mounting seat 8 and are located on both sides of the mounting seat 8. The first fabric 3 is disposed closely against the front surface 41 or the back surface 42 of the aluminum foil 4, and its unwinding direction is opposite to the unwinding direction of the aluminum foil 4. To facilitate adjusting the tightness of the fabric between the winding wheel set 22 and the unwinding wheel set 23 and to facilitate adjusting the better contact between the fabric and the surface of the aluminum foil 4, there is also an adjusting roller 7 parallel to its axis on one side of the unwinding roller 12. Both ends of the adjusting roller 7 are connected to the housing 11 of the aluminum foil unwinding mechanism 1. The inner side surface of the first fabric 3 is in sliding contact with the adjusting roller 7. The gap between the adjusting roller 7 and the unwinding roller 12 can accommodate the aluminum foil 4 and the first fabric 3. The outer side surface of the first fabric 3 is closely against the front surface 41 of the aluminum foil 4.

[0036] See Figure 4 and Figure 5As shown in the figure, the alcohol drip irrigation is arranged on one side of the fabric and can deliver an alcohol solution to the first fabric 3. Regarding the installation position of the alcohol drip irrigation, it is convenient to place the alcohol solution therein on the fabric. The alcohol drip irrigation is arranged on the side of the mounting seat 8 close to the adjusting roller 7. The liquid outlet 271 of the alcohol drip irrigation is inclined downward towards the inner side of the first fabric 3. The alcohol output from the liquid outlet 271 can drip on the first fabric 3 and penetrate the first fabric 3. The alcohol is smeared on the surface of the aluminum foil 4 through the first fabric 3, which also facilitates the uniform dispersion of the alcohol solution on the surface of the aluminum foil 4. The specific structure of the above-mentioned alcohol drip irrigation is that the alcohol drip irrigation includes a tank body 26 and a liquid outlet head 27 connected in communication. The liquid outlet head 27 is arranged close to the adjusting roller 7, and the liquid outlet 271 of the liquid outlet head 27 is arranged close to the inner side of the first fabric 3 at a lower position. The liquid outlet 271 is arranged at the lower part of the liquid outlet head 27, and the liquid outlet head 27 is a long-shaped hollow structure. The length direction of the liquid outlet head 27 is the same as the width direction of the first fabric 3, which is convenient for dripping alcohol on the first fabric 3 along the width direction of the first fabric 3. The tank body 26 is connected to an external alcohol liquid outlet pump through a hose, and the liquid output volume of the liquid outlet 271 can be controlled through the alcohol liquid outlet pump.

[0037] In this embodiment, a first aluminum foil wiping mechanism 2 is installed on one side of the front side 41 of the carbon-coated aluminum foil 4. The front side 41 of the aluminum foil 4 is wiped with a fabric with an alcohol solution by the first aluminum foil wiping mechanism 2. The fabric is unwound and wound through the unwinding wheel set 22 and the winding wheel set 23. The fabric that contacts and smears alcohol on the surface of the aluminum foil 4 will leave impurities after contacting the surface of the aluminum foil 4. The used fabric is wound by the winding wheel set 22, so that the surface of the aluminum foil 4 is always in contact with a clean fabric with an alcohol solution, reducing the influence of impurities on the fabric on the subsequent coating of ceramics or other coatings on the aluminum foil 4.
