Description
Technical Field
[0001] The utility model relates to the technical field of film processing, and particularly relates to a film surface printing and drying device. Background Technique
[0002] A film is a thin and soft sheet made of plastic, adhesive, rubber or other materials, and is widely used in various fields of production and life. In different application environments, sometimes it is necessary to perform printing treatment on the film surface, and the printed film surface needs to be dried and processed to make the printing fixed.
[0003] The existing printing and drying equipment for film surface processing has the following disadvantages when in use: when drying the film surface printing, generally ordinary drying equipment is used for drying, and the temperature needs to be strictly controlled during the drying process. At the same time, the existing drying components will cause the film material to be in a high-temperature state after drying. During the subsequent winding and processing, affected by the high temperature, it is easy to cause deformation of the film material and discoloration of the printing. For this reason, we propose a film surface printing and drying device. Content of the Utility Model
[0004] The main purpose of the utility model is to provide a film surface printing and drying device. By setting a drying mechanism inside the oven, it not only ensures a good drying effect, but also reduces the influence of drying on the quality of the film material, and can effectively solve the problems in the background technique.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A film surface printing and drying device includes an oven and also includes a drying mechanism. The drying mechanism is arranged inside the oven. The drying mechanism includes a fan, a wind hood, a shunt pipe, an electric heating wire and a cooling plate. A fan is installed on one side of the outer wall of the oven, and a wind hood is installed on the top of the inner wall of the oven. The exhaust end of the fan is installed with a shunt pipe and is connected to the air inlet end of the wind hood through the shunt pipe. An electric heating wire is installed inside the shunt pipe near the film material input end on one side inside the oven, and cooling plates are arranged on both sides inside the oven.
[0007] Furthermore, it also includes a water cooling mechanism. The water cooling mechanism is arranged inside the cooling plate. The water cooling mechanism includes a cooling cavity, an arc-shaped convex ring and a partition. A cooling cavity is opened inside the cooling plate, and a partition is fixedly connected inside the cooling cavity. An arc-shaped convex ring is arranged on the top of the cooling plate; after the film material enters the oven, it first passes through the surface of the cooling plate. The surface of the cooling plate is designed with an arc-shaped convex ring structure, so that the film material can contact the top of the cooling plate more smoothly during the conveying process. The cooling cavity located inside the cooling plate is used to inject cooling water. After the cooling water is injected, the partition structure inside the cooling cavity is used to guide and convey the water flow, so that the water flow evenly passes through the inside of the cooling cavity and is discharged.
[0008] Furthermore, a heat radiation lamp is provided on one side inside the oven, and the heat radiation lamp is located between the air hood and the cooling plate; when the film material enters the hot air area, the heat radiation energy generated by the heat radiation lamp is first used to preliminarily dry the printing, and after preliminary shaping, it enters the hot air area.
[0009] Furthermore, guide rollers are provided at both ends inside the oven at the positions where the film material enters and exits; the guide rollers inside the oven play a guiding role in the transportation of the film material.
[0010] Furthermore, a water inlet pipe and a drain pipe communicating with the inside of the cooling cavity are installed at one end of the surface of the cooling plate, and both ends of the water inlet pipe and the drain pipe are located outside the oven; an external cooling water circulation device is connected through the water inlet pipe and the drain pipe to realize the circulating supply of cooling water inside the cooling cavity.
[0011] Compared with the prior art, the utility model has the following beneficial effects: Cooling plates are provided on both sides inside the oven. The printed film material passes through the inside of the oven under the action of the conveying device. The guide rollers play a guiding role so that the film material can be attached to the surface of the cooling plate. On one side at the film material inlet end, by using the cooling plate to contact the bottom surface of the film material, the bottom surface can be pre-cooled and cooled, and then continue to be conveyed. The radiant heat energy of the heat radiation lamp is used for preliminary shaping of the printing. The wind generated by the fan enters the air hood through the shunt pipe. The hot air is discharged from the air hood on the side close to the heat radiation lamp to further shape and fix the printing, while the cold air that has not been heated is discharged from the other air hood, which can quickly cool and cool the surface of the shaped film material, avoiding the film material being in a high temperature state for a long time and problems such as film material aging and printing color change. The film material is then discharged after secondary cooling by the cooling plate at the discharge end; after the film material enters the inside of the oven, it first passes through the surface of the cooling plate. The surface of the cooling plate is designed with an arc-shaped convex ring structure, so that the film material can contact the top of the cooling plate more smoothly during the conveying process. The cooling cavity inside the cooling plate is used to inject cooling water. After the cooling water is injected, the partition structure inside the cooling cavity plays a guiding and conveying role for the water flow, so that the water flow evenly passes through the inside of the cooling cavity and is discharged.

The exhaust end of the fan 201 is installed with a shunt pipe 203 and is connected to the air inlet end of the air hood 202 through the shunt pipe 203. An electric heating wire 204 is installed inside the shunt pipe 203 on one side close to the film material input end inside the oven 1. Cooling plates 205 are arranged on both sides inside the oven 1.

The water cooling mechanism 3 includes a cooling cavity 301, an arc-shaped convex ring 302 and a partition board 303. A cooling cavity 301 is opened inside the cooling plate 205 and a partition board 303 is fixedly connected inside the cooling cavity 301. An arc-shaped convex ring 302 is arranged on the top of the cooling plate 205; after the film material enters the oven 1, it first passes through the surface of the cooling plate 205. The surface of the cooling plate 205 adopts an arc-shaped convex ring 302 structure design, so that the film material can contact the top of the cooling plate 205 more smoothly during the conveying process. The cooling cavity 301 located inside the cooling plate 205 is used to inject cooling water. After the cooling water is injected, the partition board 303 structure inside the cooling cavity 301 is used to guide and convey the water flow, so that the water flow evenly passes through the inside of the cooling cavity 301 and is discharged.
[0020] Among them, a heat radiation lamp 206 is provided on one side inside the oven 1. The heat radiation lamp 206 is located between the air hood 202 and the cooling plate 205. Guide rollers 207 are provided at both ends inside the oven 1 at the positions where the film material enters and exits. When the film material enters the hot air area, the heat radiation energy generated by the heat radiation lamp 206 is first used to preliminarily dry the printing, and after preliminary shaping, it enters the hot air area. The guide rollers 207 inside the oven 1 play a guiding role in the transportation of the film material.
[0021] Among them, a water inlet pipe 304 and a drain pipe 305 communicating with the inside of the cooling cavity 301 are installed at one end of the surface of the cooling plate 205.

[0022] It should be noted that the present utility model is a film surface printing drying device. When in use, cooling plates 205 are provided on both sides inside the oven 1. The printed film material passes through the inside of the oven 1 under the action of a conveying device.

The radiation heat energy of the heat radiation lamp 206 is used for preliminary shaping of the printing. The wind generated by the fan 201 enters the air hood 202 through the shunt pipe 203. The hot air is discharged from the air hood 202 on the side close to the heat radiation lamp 206 to further shape and fix the printing, while the unheated cold air is discharged from the other air hood 202, which can quickly cool and cool the surface of the shaped film material, avoiding the problems of the film material being in a high temperature state for a long time, film material aging and printing color change, etc. The film material is then discharged after secondary cooling by the cooling plate 205 at the discharge end. After the film material enters the inside of the oven 1, it first passes through the surface of the cooling plate 205. The surface of the cooling plate 205 is designed with an arc-shaped convex ring 302 structure, so that the film material can contact the top of the cooling plate 205 more smoothly during the conveying process. The cooling cavity 301 inside the cooling plate 205 is used to inject cooling water. After the cooling water is injected, the partition 303 structure inside the cooling cavity 301 plays a guiding and conveying role for the water flow, so that the water flow evenly passes through the inside of the cooling cavity 301 and is discharged.
