Problems solved by technology

[0002] Electrostatic ions are attached to the film of aluminum-plated products. Due to the influence of raw materials, coatings, ambient temperature, humidity and other factors, static electricity will be generated during aluminum plating, which will cause product deformation, film zigzag and black lines, etc., and in BOPP transfer film and other non- Electrostatic tree marks will be generated when aluminum is plated on polar plastic films; static electricity removal treatment is required before coating; due to the material relationship of BOPP film, wrinkles are prone to occur during coating

Embodiment Construction

[0033] Such as Figure 1-12 Shown, a kind of coating process for BOPP electrical film, comprises the following steps:

[0034] a. Prepare accessories;

[0035] b. Sanitation of cleaning equipment;

[0036] c. Equipment preheating;

[0037] d. Use a feeder to send BOPP into the coating machine; first place the BOPP film on the moving block 10, and drive the moving block 10 to move laterally; The film is sucked on the rotating disk 21; the docking device 2 includes a rotating disk 20, a transition cavity 22, a fixed block 23, and a docking mechanism 3; the rotating disk 20 is rotatably embedded in the bottom of the transition chamber 11; the transition chamber 22 is provided with 4, the cross section is fan-shaped, is arranged on the upper end surface of rotating disc 20; Said fixed block 23 is arranged in each transition chamber 22; Said docking mechanism 3 is arranged on the fixed block 23; Before coating, transition The air extractor on the warehouse 11 starts to pump the...

Abstract

The invention discloses a film coating process for a BOPP electrical film. The film coating process comprises the following steps: a, preparing auxiliary materials and accessories; b, cleaning equipment is sanitary; c, preheating equipment; d, feeding the BOPP into a coating machine by adopting a feeding machine; firstly, a BOPP film is placed on a moving block, and the moving block is driven to move transversely; when the moving block moves to the transition bin, the butt joint device is started, and the BOPP film is sucked on the transition disc; the butt joint device comprises a rotating disc arranged on the transition cavities, a plurality of transition cavities formed in the rotating disc, fixing blocks arranged in the transition cavities and butt joint mechanisms arranged on the fixing blocks. The device is simple in structure, and pretreatment before film coating is facilitated; the BOPP film can be subjected to static electricity removing treatment before film coating, and the influence of static electricity during film coating is prevented; and meanwhile, during feeding, connection with air exhaust can be achieved, so that the BOPP film is more stable during film coating, and dislocation is avoided.

Description

technical field [0001] The invention belongs to the technical field of coating, and in particular relates to a coating process for BOPP electrical film. Background technique [0002] Electrostatic ions are attached to the film of aluminized products. Due to the influence of raw materials, coatings, ambient temperature, humidity and other factors, static electricity will be generated during aluminizing, which will cause product deformation, film zigzag and black lines, etc., and in BOPP transfer film and other non- Electrostatic tree marks will be generated when aluminum is plated on polar plastic films; static electricity removal treatment is required before coating; due to the material relationship of BOPP film, wrinkles are prone to occur during coating. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a coating process for BOPP electrical film. [0004] In order to achieve the above object, the pr...
