Description

Technical Field

[0001] The utility model belongs to the technical field of film drying, in particular to a film drying device. Background Art

[0002] The related technology discloses a film drying device with announcement number CN219368302U. The device uses a hot oil pipeline on a heating plate to heat the air blown out by the air supply mechanism, thereby increasing the temperature of the air blown to the drying bracket, thereby drying the film and ensuring the efficiency of film drying. This device uses a hot oil pipeline to heat the blowing air, avoiding the use of electrical equipment, and avoiding moisture contacting the electrical equipment during drying to cause leakage and short circuit, thereby improving the safety of the device.

[0003] However, when the device is in use, the film may be heated unevenly, resulting in a higher temperature in the area of ​​the film close to the air supply mechanism, while the temperature in the area of ​​the film away from the air supply mechanism is lower, resulting in inconsistent drying degrees at different positions of the film, which may affect the flatness of the film and cause wrinkles on the surface of the film.

[0011] Furthermore, the fixing assembly includes a plurality of sliding grooves opened at the left end and the right end of the drum, and the inner bottom walls of the plurality of sliding grooves are fixedly connected with springs.

[0012] Furthermore, one end of several of the springs away from the inner bottom wall of the corresponding chute is fixedly connected to a limit plate, and several of the limit plates are slidably connected to the corresponding chute.

[0015] The utility model has the following beneficial effects:

[0016] 1. By setting up an induced draft mechanism, start motor 1, and motor 1 drives shaft 1 to rotate. When shaft 1 rotates, it drives the gear fixedly connected to shaft 1 to rotate. When the gear fixedly connected to shaft 1 rotates, it drives the gear connected to shaft 2 to rotate. When the gear rotates, it drives the fixed rod to rotate. When the fixed rod rotates, it drives connecting plate 1 to move. When connecting plate 1 moves, it drives the induced draft plate to move on sliding rod 1. The induced draft mechanism can continuously change the flow direction of the hot air in the drying box. The hot air in the drying box is no longer a simple one-way flow or a static state. The hot air forms a circulating flow in the drying box, distributing the heat more evenly to every corner, so that the film at any position in the drying box can receive relatively uniform heat, thereby improving the drying quality and reducing the deformation of the film or uneven drying caused by local temperature differences.

The rotating mechanism allows the film to rotate during the drying process, so that all parts of the film can be heated evenly, and thus every part of the film has the opportunity to directly contact the hot air flow, avoiding the situation where some areas are overheated and some areas are underheated due to local obstruction or uneven air flow. At the same time, the rotation of the film helps to renew the air layer on the surface of the film, and can continuously replace the air on the surface of the film, allowing fresh and dry air to contact the surface of the film, thereby accelerating the vaporization rate of moisture, thereby improving the drying efficiency.

[0029] The rotating mechanism 3 includes a rotating assembly and a fixed assembly. The rotating assembly includes a motor 2 31 fixedly connected to the right side of the drying box 1. The output shaft of the motor 2 31 is fixedly connected to the rotating shaft 32 through a shaft coupling. The left end of the rotating shaft 32 extends to the interior of the drying box 1 and is rotatably connected to the drying box 1. The roller 33 is fixedly connected to the rotating shaft 32. The fixed assembly includes a plurality of slide grooves 34 opened at the left and right ends of the roller 33. The inner bottom walls of the plurality of slide grooves 34 are fixedly connected to springs 35. The ends of the plurality of springs 35 away from the inner bottom walls of the corresponding slide grooves 34 are fixedly connected to limit plates 36. The plurality of limit plates 36 are slidably connected to the corresponding slide grooves 34. The sides of the plurality of limit plates 36 away from the corresponding springs 35 are fixedly connected to slide rods 2 37.

[0030] A specific application of this embodiment is as follows: the blower 210 is started, and the blower 210 blows air into the drying box 1. The wind blown into the drying box 1 by the blower 210 is guided by the guide plate 211 to reduce the diffusion of the wind and make the wind force more concentrated. The wind blown into the drying box 1 is heated by the heating plate 212 and the steam pipe 213, and the heated hot air dries the film. At the same time, the motor 1 21 is started, and the motor 1 21 drives the rotating shaft 1 22 to rotate. When the rotating shaft 1 22 rotates, it drives the gear 24 fixedly connected to the rotating shaft 1 22 to rotate. When the gear 24 fixedly connected to the rotating shaft 1 22 rotates, it drives the gear 24 connected to the rotating shaft 23 to rotate. When the gear 24 rotates, it drives the fixed rod 25 to rotate. When the fixed rod 25 rotates, it drives the connecting plate 1 28 to move. When the connecting plate 1 28 moves, it drives the air induction plate 27 to move on the sliding rod 1 26. The gear 24 fixedly connected to the rotating shaft 23 and the fixed rod 23 rotate. The fixed rod 25 is eccentrically connected, so that the movement of the air induction plate 27 forms convection of the air inside the drying box 1. When the two air induction plates 27 move closer to or farther away from each other, the two air induction plates 27 will drive the nearby hot air to move with them during the movement, so that the hot air will continue to follow the movement of the two movable plates 27 in the drying box. When the two movable plates 27 approach each other, they will drive the hot air from the left and right sides of the drying box 1 to the middle position of the drying box 1. When the two movable plates 27 move away from each other, they will drive the hot air in the middle position of the drying box 1 to move to the left and right sides of the drying box 1, thereby constantly changing the flow direction of the hot air in the drying box 1, so that any position in the drying room can receive more uniform heat, thereby improving the drying quality. At the same time, the air induction plate 27 is limited by the sliding rod 1 26 to prevent the air induction plate 27 from deviating from a certain path when moving.

[0031] The sealing door 311 is opened and the film to be dried is wound on the roller 33. Before winding the film, the springs 35 on the inner walls of the four slide grooves 34 are reset under their own elastic action. The four slide grooves 34 are evenly distributed at the left and right ends of the roller 33. The two slide grooves 34 at the same end of the roller 33 are coaxial and the axis passes through the center of the end face of the roller 33. When the four springs 35 are reset, they drive the corresponding slide rods 37 to move away from the axis of the roller 33, and then drive the four curved plates 39 to move, so that the corresponding two curved plates 39 are easy to separate, and then the film is wound on the roller 33. After the film is wound on the roller 33, the corresponding two curved plates 39 are close to each other. At this time, the curved plates 39 will drive the slide rods 37 to move closer to the center of the roller 33. The film is fixed by the bolt 310, thereby preventing the film from rotating and falling during the subsequent drying process. When the film is fixed, the sealing door 311 is closed, and the motor 1 21 and the blower 210 are started to dry the film. Then the motor 2 31 is started, and the motor 2 31 drives the shaft 32 to rotate. When the shaft 32 rotates, it drives the roller 33 to rotate, thereby driving the film on the roller 33 to rotate, so that every part of the film has the opportunity to directly contact the hot air flow, avoiding the situation where some areas are overheated and some areas are underheated due to local obstruction or uneven air flow.
