What is a wrapping machine used for?
What is a wrapping machine:
The wrapping machine is suitable for the production of decorative paint paper, PVC, solid wood veneer laminated on the surface of various lines such as wood, aluminium-plastic profiles, foaming materials and so on. Instead of the traditional painting process, it is used for the production of aluminium alloy doors and windows, door set lines, window sills, curtain rods, photo frames and other surface laminating.
Working Principle:
Adopting all kinds of moulding pressure wheels, simulating manual laminating action, attaching the surface decorative material to the surface of the substrate, generally choosing the centre line or the highest point or the lowest point of the profile as the starting point, and fixing the pressure wheels along the profile surface contour, point by point, and in turn, to form the envelope of the profile contour.
Wrapping material:
1、Substrate material: wood line, MDF, wood plastic, plastic steel, PVC, aluminium profiles and other lines. Substrate requirements: for the rule line profile, there can be grooves, curved surfaces, but each point longitudinally must be a straight line, with a certain degree of pressure resistance, the length of the general length of more than 40 cm to unlimited length.
2, veneer materials: PVC decorative film, decorative paper, solid wood veneer, Boeing board, composite aluminium film. The width is determined according to the needs of the substrate and the selected model, generally less than 50 cm. For example, the widest laminating width of 300 universal wrapping machine is 30cm. Generally used in rolls. There are also extra wide profiles of about 100cm on the market. Solid wood veneer can be rolled or single, solid wood veneer is generally the bottom with a non-woven fabric, without non-woven surface material shall not be permeable to glue, in the corner and easy to break.
Machine type:
Wrapping machine is generally divided into two types: cold glue and PUR hot glue.
1, cold glue wrapping machine using liquid glue. Liquid glue can be divided into solvent glue and water-based glue.
There are two types of glue coating: scraping and roller coating. The volatile solvent glue is coated by scraping.
The glue box is easy to be closed to prevent the volatility of the wrapping glue. Water-based adhesives and solvent-based adhesives with low volatility are generally coated by rollers, which is easy to operate.
Water-based adhesive and solvent adhesive with low volatility are usually coated by roller, which is easy to operate.
2、PUR hot glue wrapping machine, the use of solid adhesive, in the coating machine hot glue box Inside the hot glue box of the wrapping machine is heated and dissolved and then used, generally the heating temperature of the wrapping glue is about 220℃. Suitable for covering solid wood veneer and decorative paint paper.
3、Combination wrapping machine, in order to meet the different production needs, universal wrapping machine In order to meet different production needs, universal wrapping machine has cold glue hot glue combination type, cold glue scraping coating roller coating combination type, mesh cloth special type and so on.
