[0003] When drying the aluminum foil surface with paint on it, the paint may not adhere well to the foil surface due to various reasons, such as improper surface treatment of the foil, improper drying temperature, uneven coating thickness, and inappropriate humidity of the coating environment, thus having a negative impact on product quality. Utility Model Content

[0004] The utility model aims to provide an aluminum foil surface coating drying device.

[0005] The technical problem solved by the utility model is that during the drying process of the aluminum foil surface, due to various reasons, the coating adhesion is poor, which in turn has a negative impact on the quality of the product.

[0024] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0025] See also Figure 1-3 As shown, the present embodiment provides an aluminum foil surface coating drying device, comprising a mounting frame 1, a pair of conveying rollers 2 are rotatably mounted on the front and rear sides of the mounting frame 1, a sprayer 3, a pair of coating rollers 4, and two vertically symmetrical extrusion assemblies 5 are arranged in sequence from front to back between the two pairs of conveying rollers 2, the coating rollers 4 are rotatably connected to the mounting frame 1, a heating plate 6 is arranged on the front and rear sides of the extrusion assembly 5, a support plate 7 is fixedly mounted on one side of the mounting frame 1 adjacent to the sprayer 3, a pressure switch 8 electrically connected to the sprayer 3 is fixedly mounted on the support plate 7, a heater is installed on the top of the heating plate 6, and push-pull assemblies 9 for causing the two extrusion assemblies 5 to move toward each other are arranged on both sides of the mounting frame 1;

[0026] The two pairs of conveying rollers 2 are used to limit the conveying track of the aluminum foil surface. When the pressure switch 8 is squeezed, the nozzle of the sprayer 3 is closed, otherwise it is opened. When the sprayer 3 is turned on, the coating is sprayed onto the surface of the aluminum foil surface. After the sprayed aluminum foil surface is conveyed between a pair of coating rollers 4, the coating rollers 4 roll the coating evenly on the aluminum foil surface, and then convey it to the bottom of the first heating plate 6 for preheating, and then convey it between the two extrusion components 5 for extrusion, and then it is thoroughly dried by the second heating plate 6;

[0027] The extrusion assembly 5 includes a sliding bracket 51 that is slidably installed on the mounting frame 1, a pair of sliding rods 52 are slidably installed on both sides of the top of the sliding bracket 51, a fixing plate 53 is fixedly installed on the top of the pair of sliding rods 52, a plurality of springs 54 are fixedly installed between the fixing plate 53 and the sliding bracket 51, and an extrusion plate 55 is fixedly installed on the bottom of the two pairs of sliding rods 52;

[0028] The push-pull assembly 9 includes a rotating plate 91 rotatably mounted on one side of the mounting frame 1 adjacent to the extrusion assembly 5, a push-pull plate 92 is rotatably mounted on the top of the rotating plate 91, and two mutually symmetrical connecting plates 93 are rotatably mounted on one end of the push-pull plate 92 away from the rotating plate 91, and the two connecting plates 93 are rotatably connected to one end of the two sliding brackets 51 respectively;

[0029] The rotating rotating plate 91 pushes and pulls the two symmetrical connecting plates 93 to push and pull the two sliding brackets 51, so that the two sliding brackets 51 move toward each other. When the push and pull plate 92 pulls the two connecting plates 93, the distance between the two sliding brackets 51 becomes smaller, and vice versa. When the preheated aluminum foil surface is transported between the two extrusion components 5, the two extrusion components 5 simultaneously squeeze the aluminum foil surface to enhance the adhesion between the coating and the aluminum foil. At this time, the extrusion plates 55 in the two extrusion components 5 squeeze the fixed plate 53 through the two pairs of sliding rods 52, so that the fixed plate 53 stretches the spring 54, and then the spring 54 is in a stressed state. The spring 54 reacts on the extrusion plate 55, so that the two extrusion plates 55 clamp the aluminum foil surface, remove the unevenness between the aluminum foil surface and the coating layer, so as to enhance the adhesion between the coating and the aluminum foil surface, and make the connection between the coating and the aluminum foil surface more firmly.

[0030] A half-circle gear 10 is rotatably installed at a position near the rotating plate 91 on one side of the mounting frame 1, and a driving motor (not shown in the figure) for driving the half-circle gear 10 to rotate is installed on the mounting frame 1. A full gear 11 meshing with the half-circle gear 10 is rotatably installed on one side of the mounting frame 1. The full gear 11 and the conveying roller 2, and the half-circle gear 10 and the rotating plate 91 are all driven by pulleys. A push-pull plate 12 is slidably installed through the support plate 7, and a pressing plate 13 is fixedly installed at one end of the slide rod 52. The other end of the push-pull plate 12 is rotatably connected to the end of the push-pull plate 1 92 away from the rotating plate 91;

[0031] The rotating half-circle gear 10 drives the full gear 11 to rotate intermittently, and the full gear 11 drives the conveying roller 2 to rotate synchronously through the pulley, so that the conveying roller 2 intermittently drives the aluminum foil surface to move toward the rear side of the mounting frame 1, and at this time, the rotating half-circle gear 10 drives the rotating plate 91 to rotate synchronously through the pulley. When the aluminum foil surface moves, the rotating plate 91 drives the push-pull plate to push the two connecting plates 93, so that the two extrusion components 5 moving in opposite directions are separated from each other to avoid the extrusion components 5 hindering the movement of the aluminum foil surface. When the two extrusion components 5 moving in opposite directions clamp the aluminum foil surface, the conveying roller 2 stops rotating, so that the aluminum foil surface stops moving. Then, after the two extrusion components 5 are separated from the surface of the aluminum foil surface, the conveying roller 2 rotates again to drive the aluminum foil surface to move again.

[0032] When the push-pull plate 1 92 pulls the two connecting plates 93 to make the two extrusion components 5 clamp the aluminum foil surface, the push-pull plate 2 12 is pulled, so that the push-pull plate 2 12 drives the pressing plate 13 to squeeze the pressure switch 8, thereby turning off the sprayer, and then when the aluminum foil surface stops moving, the sprayer is turned off to avoid uneven spraying on the aluminum foil surface. When the two extrusion components 5 are separated from the aluminum foil surface, the push-pull plate pushes the push-pull plate 2 12, so that the push-pull plate 2 12 drives the pressing plate 13 to separate from the squeezing of the pressure switch 8, thereby turning on the sprayer, and the sprayer 3 moves on the aluminum foil surface to spray paint on it, so as to ensure that the paint is evenly sprayed on the aluminum foil surface.

[0033] When the utility model is in use, the aluminum foil surface is passed through from front to back in sequence, between the conveying rollers 2, between the coating rollers 4, and between the two extrusion assemblies 5, and then passed out from between the conveying rollers 2 on the rear side of the mounting frame 1, so that the half-circle gear 10 rotates, and the conveying roller 2 is driven to rotate intermittently through the full gear 11. At this time, the rotating plate 91 rotates synchronously with the half-circle gear 10, and then the rotating plate 91 drives the two extrusion assemblies 5 to move toward each other by pushing and pulling one and two connecting plates 93, and the aluminum foil surface is driven to move intermittently through the intermittently rotating rollers. When the aluminum foil surface moves, the two extrusion assemblies 5 are separated from the surface of the aluminum foil surface, and the sprayer 3 is turned on to spray the paint on the surface of the aluminum foil surface. When the aluminum foil surface stops moving, the two extrusion assemblies 5 just clamp the aluminum foil surface preheated by the first heating plate 6, and the sprayer 3 is just turned off. When the paint is firmly attached to the aluminum foil surface, the two extrusion assemblies 5 are separated from the surface of the aluminum foil surface again, and the aluminum foil surface is moved to the second heating plate 6 for heating, thereby completely drying the paint.
