TECHNICAL FIELD

[0001] The utility model relates to the technical field of film processing, especially to a resin smearing structure for packaging film processing coating. BACKGROUND

[0002] A resin smearing structure for packaging film processing coating generally involves applying a specific type of resin in the form of a coating to the surface of a film to enhance its performance or meet specific application requirements. The structure mainly consists of a resin coating and a film substrate.

[0003] The resin coating is uniformly applied to the surface of the film substrate through specific process means such as spraying, dipping, and scraping. This resin coating may contain various components such as film-forming substances (mainly composed of resin), solvents (used to adjust the viscosity and workability of the coating), pigments and fillers (used to improve the decorative and performance of the coating), and additives (used to improve the production process and coating performance).

[0004] However, the traditional resin smearing structure for packaging film processing coating, after the resin coating is applied, the wet resin coating is prone to dripping from the film, making it difficult to clean the table.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0023] The resin smearing structure for packaging film processing coating disclosed by the utility model mainly applies to the scene that the undried resin coating is easy to drip from the film after the resin coating is smeared, leading to the difficulty in cleaning the table top.

[0024] Referring to Figure 1 , Figure 3 , Figure 4 and Figure 5 , a resin smearing structure for packaging film processing coating, comprising a chassis 1, a conveying assembly, a first support table 12, a second support table 13 and a film body 2, further comprising: a preheating mechanism: the preheating mechanism is arranged on the opposite side inner wall of the chassis 1, the opposite side inner wall of the chassis 1 is provided with a same assembly frame 6, three groups of air outlets 16 are formed in the opposite side inner wall of the assembly frame 6, each group has two air outlets 16, an inner wall of one of the air outlets 16 is provided with a fan 15, and one end of each group of air outlets 16 is provided with a conveying pipe 7, three heat conduction rollers are arranged on the opposite side inner wall of the assembly frame 6, a plurality of equidistantly arranged air deflectors 14 and two support frames 17 are arranged on the circumferential inner wall of the heat conduction roller, and a same electric heating wire 18 is arranged on the opposite side outer wall of the two support frames 17; a stirring mechanism: the stirring mechanism is arranged on the top outer wall of the first support table 12.

[0025] In the specific embodiment, the preheating mechanism heats by the electric heating wire 18, preheats the smearing film body 2 to a suitable temperature, improves the coating adhesion, effectively prevents the resin from dripping on the table top before drying, shortens the subsequent baking period, improves the overall operation efficiency of the production line, the air deflectors 14 can help the heat to be evenly distributed, the structure thereof prolongs the effective temperature area of the heat conduction roller, the setting of the fan 15 and the conveying pipe 7 realizes the circulation of heat, avoids the film scalding problem caused by the high temperature of the electric heating wire 18, a temperature sensor is arranged in the heat conduction roller, the temperature inside the heat conduction roller is monitored in real time by the temperature sensor, the preheating temperature can be accurately controlled, and the film is preheated in a suitable temperature range.

[0026] For example, in actual application, after the film body 2 on the production line passes through the resin coating, the heat conduction roller of the preheating mechanism preheats the film to a suitable temperature range, which can ensure that the resin coating does not drip due to incomplete drying and provide a good starting point for the subsequent baking process.

[0027] With reference to Figure 1 , Figure 2 and Figure 3 , in a preferred embodiment, the conveying assembly includes two guide rollers 4, a pressing roller 5, a feeding roller 8, and a collecting roller 9, all of which are arranged on the inner walls of the opposite sides of the chassis 1.

[0028] The coordinated work of the two guide rollers 4, the pressing roller 5, the feeding roller 8, and the collecting roller 9 in the conveying assembly ensures the rapid transmission and efficient processing of the film during the processing, thereby improving the production efficiency. The arrangement of the two guide rollers 4 ensures the smooth transmission of the film body 2 during the processing, which can guide the film to move along the predetermined path and avoid the deviation or jamming of the film during the transmission. When the resin is coated, the pressing roller 5 can apply a certain pressure to the film, so that the resin coating is more tightly attached to the surface of the film, improving the adhesion and uniformity of the coating.

The entire process is completed in one go, reducing intermediate links and transfer time and improving production efficiency. The cooperation of the coating roller 10 and the pressing roller 5 can ensure that the resin coating is fully pressed and uniformly distributed on the film. The uniform pressure of the pressing roller 5 helps to eliminate bubbles and voids in the coating, improving the adhesion and density of the coating.

[0034] The oblique arrangement of the assembly frame 6 makes the contact between the heat conducting roller and the film body 2 more closely and uniformly, which helps to more effectively transfer heat from the heat conducting roller to the film body 2, thereby improving the preheating efficiency. The oblique assembly frame 6 can also ensure that the film maintains a certain tension during transmission, avoiding relaxation or wrinkling, further ensuring the uniformity of heat transfer.

[0035] Working principle: in use, the film body 2 starts from the feeding roller 8, is conveyed through the guide roller 4, is stained with the resin paint uniformly stirred by the stirring mechanism by the paint roller 10, is coated by the pressure roller 5, is heated by the heating wire 18 after coating, and is heated by the fan 15, the air deflector 14 and the conveying pipe 7 to uniformly distribute heat in the heat conducting roller, thereby heating the back of the coated film body 2 to prevent the resin from dripping on the table before drying, and finally entering the oven 3 for baking and curing, and finally winding the film body 2.
