Shandong Alva Machinery Co., Ltd. has focused on the woodworking machinery field for 30 years. Adhering to the corporate tenet of "Creating value for customers and benefits for partners", the company takes "Product quality is produced, not inspected" as its core business philosophy. Every product undergoes research and development, practical application and strict quality inspection.
With reliable quality, its products have passed multiple international authoritative certifications including CE and SGS, and are sold well in both domestic and foreign markets. They not only occupy a significant position in the domestic woodworking machinery sector, but also successfully completed the installation and commissioning of veneer peeling machine production lines in Vietnam and other regions, helping local enterprises enhance their production capacity and market competitiveness.
Meanwhile, the company has established a comprehensive service system, providing services such as overseas equipment installation and commissioning, operator training, and 24-hour online consultation. Both the whole machine and key components are covered by warranty, with the after-sales team responding within 48 hours. In addition, the company offers product customization and personalized packaging services to fully meet the needs of customers at home and abroad.
The plywood gluing machine is a core coating equipment specially designed for modern plywood production lines. With "precision glue control, high efficiency and energy saving, and stable reliability" as its core design concepts, it is highly compatible with various veneer materials such as poplar, eucalyptus and pine.
Through an integrated intelligent control system, it realizes full-process precise control of glue coating, providing key support for the firm bonding between plywood layers and the improvement of production efficiency. Adopting an industrial-grade heavy-duty structure design, the core components are carefully selected from well-known international brands.
After rigorous environmental testing and load verification, it can seamlessly connect with the front and rear processes such as glue mixers and pre-presses. It is an ideal equipment for medium and large panel enterprises to achieve high-quality and large-scale production.
According to the production order (plywood specification, veneer material), call the preset parameters through the PLC system, and set the glue application amount, gluing roller speed and pressure roller pressure.
Check the glue tank liquid level and glue temperature, confirm that the glue supply pipeline is connected normally with the glue mixer; test the operation status of the conveying mechanism, gluing roller and safety devices.
Calibrate the gluing precision, detect the uniformity of the glue film through the test-coated sample, and fine-tune the metering roller gap until the parameters meet the standards.
After the veneers are sorted by the front feeding table, they are smoothly sent into the gluing machine by the frequency conversion conveying mechanism. The soft guide wheels automatically correct the position of the veneers to prevent deviation.
For thin veneers, start the anti-wrinkle pressure wheel for auxiliary conveying; for thick veneers, the pressure roller pressure compensation is automatically triggered to ensure that the veneers fit closely with the gluing roller.
The gluing roller and metering roller operate in coordination, and evenly transfer the glue to the veneer surface according to the preset parameters. The mesh structure ensures continuous glue film without missing coating.
The glue constant temperature system controls the temperature in real time, and the return device guides the excess glue back to the glue storage tank to improve the raw material utilization rate.
After gluing, the veneers pass through the photoelectric detection device, which automatically identifies defects such as missing coating and unevenness of the glue film, and triggers an alarm and marks when there is an abnormality.
Qualified veneers are smoothly sent to the pre-press by the output mechanism to complete the process connection; defective veneers are automatically diverted to the manual re-inspection area.
After the completion of a single batch production, close the glue supply valve, start the automatic cleaning program, and rinse the gluing roller, glue tank and pipeline.
Clean the residues on the equipment surface, turn off the power supply, record the operating parameters and equipment status, and form a production log.
