[0058] The wide film environmental protection powder coating and recycling device combines

[0059] As shown in the figure, it comprises a casing 1, a powder coating mechanism 2, a powder supply mechanism 3, a powder brushing mechanism 4 and a driving device 5. The casing 1 is provided with an inlet 11 and an outlet 12. The powder coating mechanism 2 and the powder brushing mechanism 4 are installed in the closed casing 1. The wide film enters the casing 1 through the inlet 11, passes through the powder coating mechanism 2 and the powder brushing mechanism 4 in sequence and then exits through the outlet 12. The powder coating mechanism 2 is used for coating powder on both sides of the wide film. The powder supply mechanism 3 is used for supplying powder to the powder coating mechanism 2. The powder brushing mechanism 4 comprises a first brush roller 41 and a second brush roller 42. The wide film passes around the first brush roller 41 and the second brush roller 42 in sequence. The first brush roller 41 and the second brush roller 42 brush the two surfaces of the wide film respectively. The driving device 5 drives the first brush roller 41 and the second brush roller 42 to rotate.​

[0055] The powder supply mechanism 3 of the present application supplies powder to the powder coating mechanism 2. The wide film first enters through the inlet 11, then passes through the powder coating mechanism 2, and then the powder coating mechanism 2 coats powder on both sides of the wide film. Then the wide film coated with powder passes through the first brush roller 41 and the second brush roller 42 to make the powder evenly distributed on the wide film. Finally, the wide film passes out of the outlet 12 to the next process. The present application uniformly coats powder on both sides of the wide film to prevent the wide film from sticking together during subsequent processing.

[0056] Specifically, the inner side of the inlet 11 is provided with a first long brush assembly, which includes a first left long brush and a first right long brush. The tails of the first left long brush and the first right long brush are fixed on both sides of the inlet 11 respectively, and the brush heads of the first left long brush and the first right long brush are oppositely arranged. The wide film passes through the first left long brush and the first right long brush when passing through the inlet 11. The first left long brush and the first right long brush play a role in blocking and plugging to prevent powder from flying out of the inlet 11.

[0057] Preferably, the powder coating mechanism 2 includes a first baffle 21 and a second baffle 22, which form a powder coating cavity. The top of the powder coating cavity is provided with a first opening, and the bottom is provided with a second opening. The powder supply mechanism 3 supplies powder into the powder coating cavity, and the wide film enters into contact with the powder through the first opening and then passes out through the second opening. A certain amount of powder is stored in the powder coating cavity. After the wide film passes through the powder coating cavity, the powder adheres to both sides of the wide film.

[0058] Preferably, the first baffle 21 and the second baffle 22 are arranged in a "V" shape, and the top ends of the first baffle 21 and the second baffle 22 are separated to form the first opening. The bottom ends of the first baffle 21 and the second baffle 22 have a gap to form the second opening. The "V" shape makes it easier for the powder to accumulate to a certain height, and then the wide film passes through the gap between the bottom ends of the first baffle 21 and the second baffle 22 to be more easily coated with sufficient powder. The powder supply mechanism 3 adopts a tube chain conveyor, which includes a forward conveying pipe 31 and a return conveying pipe 32.

The forward conveying pipe 31 and the return conveying pipe 32 are both provided with spray holes, and the powder leaks out of the spray holes and enters the powder coating cavity through the first opening. The tube chain conveyor transports the powder located outside the machine shell 1 to the forward conveying pipe 31 and the return conveying pipe 32, and the powder leaks out through the spray holes of the forward conveying pipe 31 and the return conveying pipe 32 to be sprayed onto both surfaces of the wide film and into the powder coating cavity.

[0059] Specifically, the pipe chain conveyor transports the powder outside the casing 1 to the outgoing conveying pipe 31 inside the casing 1 through the first conveying pipe, and then into the return conveying pipe 32 through the second conveying pipe, and then into the turning mechanism through the third conveying pipe, and then completes the turning of the conveying chain after the turning mechanism, thereby realizing the circulation of the powder.

[0060] Specifically, the second conveying pipe is provided with a feeding hopper 33 for feeding of the powder mechanism 3, and the feeding hopper 33 can avoid too little powder in the return conveying pipe 32; the first conveying pipe is provided with a standby hopper 34 as a standby.

[0064] After the gas enters the first groove 211 and the second groove 221, the gas one-way passing property of the first one-way plate 212 and the second one-way plate 222 is utilized to make the powder be blown up more uniformly and reliably after the gas is blown out to adhere to the surface of the wide film, and to avoid the powder entering the first groove 211 and the second groove 221.
