[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 4 A coating device for aluminum foil processing includes a coating assembly for frictionally driving the aluminum foil to rotate and coat the aluminum foil, and also includes a folding assembly arranged on one side of the coating assembly for pushing the film to fold to the side and then performing preliminary rolling and rolling of the circumferential film. Two hot pressing assemblies for secondary heating and rolling of the side film are symmetrically arranged on the front and back of the coating assembly.

[0025] In this embodiment, the film coating assembly includes a bottom plate 101, a rotating seat 102 is arranged on the bottom plate 101, support rollers 103 and friction rollers 104 are symmetrically installed on both sides of the top of the rotating seat 102, a rotating motor 105 is installed in front of the friction roller 104, a reeling frame 106 is arranged on one side of the rotating seat 102, a film roll 107 is arranged on the top of the reeling frame 106, and a reeling motor 108 is arranged in front of the film roll 107. The rotating seat 102 is made of 45# material, and the support roller 103 is rotatably connected to the rotating seat 102, so that the width of the film on the film roll 107 is larger than the required coating. The width of the aluminum foil roll 4 is determined by placing the aluminum foil roll 4 between the support roller 103 and the friction roller 104, and pulling one end of the film on the film roll 107 to make it stick to the aluminum foil roll 4. At this time, the front and rear sides of the film extend beyond the two sides of the film. Then, the bottom plate 101 supports the rotating motor 105 through the rotating seat 102 to drive the friction roller 104 to drive the aluminum foil roll 4 to rotate under the support of the support roller 103. At the same time, the unwinding frame 106 supports the unwinding motor 108 to drive the film roll 107 to rotate and unwind synchronously, so that the film follows the rotation of the aluminum foil roll 4 and is wrapped around its surface for coating.

[0026] In this embodiment, the folding assembly includes a folding frame 201, an electric push rod 202 is arranged on the top of the folding frame 201, a moving plate 203 is installed at the extended end of the electric push rod 202, two limit rods 204 are symmetrically arranged between the moving plate 203 and the folding frame 201, two fixed plates 205 are symmetrically arranged on the side of the moving plate 203 away from the folding frame 201, a folding roller 206 is rotatably installed on the side of the fixed plate 205 away from the folding frame 201, a pressure roller 207 is rotatably installed between the two fixed plates 205, and the fixed plate 205 is shaped The shape is an L-shaped plate, and it is made of 304 stainless steel. When the film follows the rotation and just passes the position of the folding roller 206, the folding frame 201 supports the electric push rod 202 to extend and drive the moving plate 203 to move toward the aluminum foil roll 4 along the limit rod 204, so that the moving plate 203 drives the folding roller 206 through the fixed plate 205 to push the film beyond the front and rear sides of the aluminum foil roll 4 to bend, and preliminarily roll it to press it on the front and rear sides of the aluminum foil roll 4. At the same time, the pressing roller 207 rolls the film around the aluminum foil roll 4 to make it fit the aluminum foil roll 4 more closely.

[0027] In this embodiment: the hot pressing assembly includes a pressing frame 301, on which a heating roller 302 is rotatably installed, and a pressing motor 303 is arranged below the heating roller 302. The pressing frame 301 is N-shaped, and the heating roller 302 is arranged vertically. When the film moves to the position of the heating roller 302 following the rotation, the pressing frame 301 supports the pressing motor 303 to drive the heating roller 302 to rotate, and the film part that is initially rolled after folding is subjected to secondary hot pressing, so that it shrinks due to heat and fits more closely to the front and back sides of the aluminum foil roll 4.

[0028] Working principle: Make the width of the film on the film roll 107 larger than the width of the aluminum foil roll 4 to be coated. When in use, place the aluminum foil roll 4 between the support roller 103 and the friction roller 104, and pull one end of the film on the film roll 107 to make it stick to the aluminum foil roll 4. At this time, the front and back sides of the film extend beyond the two sides of the film. Then the bottom plate 101 supports the rotating motor 105 through the rotating seat 102 to drive the friction roller 104 to drive the aluminum foil roll 4 to rotate under the support of the support roller 103. At the same time, the unwinding frame 106 supports the unwinding motor 108 to drive the film roll 107 to rotate and unwind synchronously, so that the film follows the rotation of the aluminum foil roll 4 and is wrapped around its surface for coating. When the film follows the rotation and just passes the position of the folding roller 206 The folding frame 201 supports the electric push rod 202 to extend and drive the movable plate 203 to move toward the aluminum foil roll 4 along the limit rod 204, so that the movable plate 203 drives the folding roller 206 through the fixed plate 205 to push the film beyond the front and rear sides of the aluminum foil roll 4 to bend, and perform preliminary rolling on it, pressing it on the front and rear sides of the aluminum foil roll 4. At the same time, the pressing roller 207 rolls the film on the circumference of the aluminum foil roll 4 to make it fit the aluminum foil roll 4 more closely; when the film moves to the position of the heating roller 302 with the rotation, the pressing frame 301 supports the pressing motor 303 to drive the heating roller 302 to rotate, and performs secondary hot pressing on the film part that is initially rolled after folding, so that it shrinks due to heat and fits the front and rear sides of the aluminum foil roll 4 more closely.
