Problems solved by technology

[0004] When coating the existing pipelines, the primer and the outer multi-layer coatings are generally painted. The coating materials are usually prepared by personnel first, and then the pipelines are manually painted, or the pipelines are immersed in the paint to adhere to a layer, but due to the fluidity of the paint body, when the personnel paint manually, it will cause unevenness everywhere, and the immersion paint will have flow marks due to the flow of the paint, resulting in defects in the paint film. For this reason, we propose a BOPP film surface multi-layer coating method and device

Embodiment 1

[0034] A multilayer coating method of a BOPP film surface, including the following steps:

[0035] S1. Wipe the plastic pipe with a BOPP film in advance, then adjust the paint layer, intermediate coating and the paint layer;

[0036] S2. Apply the primer layer coating to the plastic tube through the coating device 1, and then dry for 4 hours;

[0037] S3. Apply the intermediate coating coating of the debugging to the outside of the plastic tube through the coating device 1, and then dry for 4 hours;

[0038] S4. Apply a tested topcoat layer coating to the outside of the plastic tube through the coating device 1, and then dry for 4 hours.

[0039] In this embodiment, please refer to figure 1 The coating apparatus 1 in the illustrated film includes a bottom table 2, and a rotating table 3 is rotated in the base 2, and the rotation table 3 is mounted with a photovation mechanism 4 for paint applications, and the drive member 5 is mounted outside the rotation table 3;

[0040] It shou...

Embodiment 2

[0051] See Figure 5 - Figure 7 The present embodiment is further explained in the first embodiment, and the clamping assembly 14 in the illustrated map includes a spray frame 27 that rotates at the bottom of the moving ring 7, and the casing frame 27 is rotated at the bottom of the closure plate, a hlamp The mounting groove 28 is opened inside, and the mounting groove 28 is inserted with a brush plate that is fitted with the outer wall of the plastic tube, and the inner portion of the mounting groove 28 is fixed at the inner position of the mounting groove 29, the splay frame. The outer side of the 27 is fixed, and the wire rod 6 is opened, and the outer sheet of the outer casing steering gear 32 is fixed to the outer side of the steering gear 32, and the rotation column 33 is rotatably connected to the bottom of the moving ring 7. The outer side of the hula frame 27 is fixed to the transmission tooth ring 34 with the steering gear 32.

[0052] It should be noted that in this aspe...

Embodiment 3

[0057] See figure 2 The present embodiment is further illustrated for other embodiments, and the coating apparatus 1 in the illustrated film includes a bottom table 2, and a turntable station 3 is rotated in the bottom 2, and the rotation table 3 is mounted with a smear body 4 for paint applications. The drive 5 is mounted outside the rotation table 3.

[0058] Among them, a connecting sleeve 44 is attached at the intermediate position of the rotation table 3, and one end of the rotation table 3 is fixed to the air nozzle 45 in communication with the connection sleeve 44.

[0059] It is worth noting that the connecting sleeve 44 in this scenario is a rubber sleeve, which can be expanded by blowing.

[0060] In this scheme, when the interaction of the connection sleeve 44 and the air supply nozzle 45 is mounted on the rotation table 3, the inner wall of the plastic conduit can be discharged to the inner wall of the plastic conduit by the connection sleeve 44, so that the plastic pi...

Abstract

The invention discloses a BOPP film surface multi-layer film coating method and device. The device comprises a primer layer, a middle coating and a finishing coat layer, and the primer layer, the middle coating and the finishing coat layer are smeared at the outer side of a plastic pipeline. According to the method, the conventional film coating method is optimized, the designed film coating device is adopted so that uniform film coating on the outer wall of the pipeline is achieved, and compared with a manual brushing and immersion film covering mode, the film covering effect is better, non-uniformity of the outer side of the film and coating flowing marks are avoided, and film flaws are reduced.

Description

Technical field [0001] The present invention relates to the field of multilayer coating film surface of the BOPP film, in particular, a multilayer coating film method and apparatus for the surface of the BOPP film. Background technique [0002] Bopp is the abbreviation of * # * biaxially oriented polypropylene * # *, the BOPP film is two-way tensile polypropylene film. [0003] The production of the BOPP film is to first form a sheet or thick film by the long tension, and then in a dedicated stretch, simultaneously or step by step at a certain temperature and setting speed. A stretching perpendicular to the vertical direction (longitudinal direction, lateral), and after appropriate cooling or heat treatment or special processing (e.g., corona, coating, etc.), the general plastic pipe is covered with BOPP film, in order to improve the life of the BOPP film, the film is applied to the outer wall of the plastic pipe, and is applied to the surface of the plastic pipe with the coating...
