Online cold glue lamination machine for WPC board

Online cold glue lamination machine for WPC board is suitable for the production of PVC, decorative paint paper and solid wood veneer on the surface of various lines such as wood, aluminum-plastic profiles, and foam materials. Instead of the traditional paint process, it is used for the production of surface laminations such as door sleeves, skirtings, gussets, curtain rods, window sills, aluminum alloy doors and windows, and photo frames.

Working principle of Online cold glue lamination machine for WPC board : Use various forming pressure rollers to simulate the action of manual veneer, and attach the surface decoration material to the surface of the substrate. Generally, the center line or the highest point or the lowest point of the profile is selected as the starting point, and the pressure roller is placed along the profile surface contour. The positions are fixed point by point and sequentially to form the envelope of the profile outline.

Covering/wrapping material of Online cold glue lamination machine for WPC board :
1. Base material: wood lines, MDF, wood plastic, plastic steel, PVC, aluminum profiles and other lines. Base material requirements: It is a regular line profile, which can have grooves and curved surfaces, but each point must be straight in the longitudinal direction, with a certain pressure resistance, and the length is generally more than 40 cm to infinite.

2. Veneer materials: PVC decorative film, decorative paper, solid wood skin, Boeing board, composite aluminum film, etc. The width is determined according to the needs of the substrate and the selected model, generally less than 50 cm. For example, the widest lamination width of the 300-type universal laminating machine is 30 cm. Generally used in rolls. There are also extra-wide profiles of about 100 cm on the market. The solid wood veneer can be rolled or single. The solid wood veneer is generally made of non-woven fabric on the bottom surface.

Online cold glue lamination machine for WPC board uses liquid glue. Liquid glue can be divided into solvent glue and water-based glue.
There are two types of blade coating and roller coating. Volatile solvent glues are applied by scraping,
The plastic box is easy to seal and prevent the coating glue from evaporating. Water-based adhesives and solvent-based adhesives with low volatility are generally used.
Apply with a roller for easy handling.

Installation and use of Online cold glue lamination machine for WPC board :
1. Determine 2-3 operators of the machine, and the equipment should be installed in a workshop with a clean environment and a flat floor. After the equipment is in place, remove the accessories on the machine, and check and verify according to the packing list.
2. Adjust the anchor bolts so that the force is evenly applied to make the fuselage reach a level state.
3. Check whether the equipment is damaged during transportation.
4. Power supply: The machine adopts 380V three-phase four-wire power supply. The power cord should be larger than 2.5mm², and the rightmost one of the incoming power line is a zero line. The machine is installed with grounding wire according to the grounding standard. Turn on the power to check whether the motor, heater, lighting, etc. are normal.
debugging:
1. Profile positioning: Take a prepared profile, and the requirements: it cannot be bent or twisted, put it on the bed conveyor wheel, and adjust the distance between the two rows of conveyor wheels according to the requirements of the profile width, shape and coating ;Adjust the width and height of the ruler and the platform to make it suitable for the covering requirements of the profile; install the guide wheels on both sides to make the profile and the direction of movement of the conveying wheel parallel.
2. Installation and adjustment of the pressure roller: Install and adjust the small pressure roller according to the profile surface profile, generally select the profile center line or section, the highest point or the lowest point of the main curve of the profile, and transition and roll along the profile profile point by point. The profile and the diaphragm are compounded together. Install the small pressure roller to balance the force of the line, and do it at the same time. There is a pressure wheel on the top, and a supporting wheel must be installed at the bottom to balance the force of the line up, down, left and right. Otherwise, there will be unrealistic phenomena at the line joints. The large plane can be gradually rolled from the center to the two sides by the small pressure roller. At the 90° corner, the small pressure roller needs to be rotated 3 times gradually. For lines with complex shapes, the small pressure rollers should be arranged naturally and cannot be forcibly formed. In particular, the covering of decorative paper should be more natural and smooth.
3. Use of plastic box or roller coating system
⑴, the operation method of cold plastic box:
①. Unloading method of the plastic box: lift the plastic box smoothly, and the plastic box will naturally separate from the platform.
②. Adjustment of the thickness of the adhesive layer: the thickness of the adhesive layer can be adjusted by turning the lifting bolts on the lower part of both sides of the plastic box.
⑵, the use of roller coating device:
Turn the squeegee shaft on the plastic box to adjust the thickness of the coating layer. Turn the adjusting handle clockwise to thicken the adhesive layer; turn it counterclockwise to thin the adhesive layer. until the glue is evenly applied.
4. Diaphragm installation and gluing adjustment
Install the cut film on the film hanging shaft, adjust the position, lift the plastic box, the film will pass through the upper film guide roller, pass through the gap at the bottom of the plastic box, add the glue into the plastic box, pull the inclined iron, The distance is slightly narrower than the diaphragm width. Adjust the screws on both sides of the front end of the plastic box to control the thickness of the glue. The thickness of the glue depends on the type of glue, generally 50-100 grams of glue per square meter.
