5 Gallon Hot Melt Glue Machine
Progressive Heating and Melting
The heating plate is located above the adhesive. When the heating plate is heated, only the upper layer of the adhesive in the bucket comes into contact with the heating plate and melts once reaching the melting point, while the lower part of the adhesive in the bucket remains unmelted. This achieves the requirement of melting only as much as needed during production.
Isolation from Air During Hot Melting
There is an O-ring seal between the rim of the heating plate and the inner rim of the adhesive bucket, which prevents the melted liquid adhesive from coming into contact with air. This solves the problem that adhesives like PUR cannot be exposed to air during melting.
Teflon Coating Protection
The outer surface of the heating plate is coated with Teflon, which prevents carbonization, ensures optimal adhesive quality, and reduces clogging.

5 Gallon Hot Melt Glue Machine
In the field of industrial production, the performance of hot melt adhesive machines directly affects production efficiency and product quality. Our 5-gallon hot melt adhesive machine stands out among many similar products with excellent technology and advanced design, providing efficient and stable adhesive solutions for multiple industries such as woodworking wrapping and bonding, textile fabric composite, PET transparent boxes, automotive interior parts, car lights, book binding, and household appliance assembly.
1、 Core technological advantages
(1) Progressive heating melting
Adopting advanced progressive heating technology to ensure uniform heating of hot melt adhesive, the transition process from solid to liquid is smooth and steady. This heating method avoids the deterioration of the adhesive caused by local overheating, effectively improves the performance of the adhesive, and enables the adhesive to maintain good fluidity and viscosity during coating, ensuring the bonding quality of the product.
(2) During hot melting, the glue is isolated from the air
A sealing structure has been specially designed for adhesives that are sensitive to air, such as PUR. An O-ring seal is installed between the groove of the heating plate and the inner ring of the glue bucket, ensuring that the melted liquid glue does not come into contact with air at all. This perfectly solves the problem of the adhesive reacting and affecting its performance due to contact with air during the melting process, ensuring that the adhesive is always in its optimal state.
2、 Humanized functional design
(1) Stepless adjustment of adhesive output
Equipped with advanced variable speed motors and pumps that can adapt to various flow rates, and driven by an AC motor through a frequency converter to drive a gear pump for glue supply, achieving stepless adjustment of glue volume. Whether it is micro coating or large-scale adhesive production needs, it can be precisely controlled to meet the diverse requirements of different products and processes for adhesive quantity, effectively avoiding adhesive waste and improving production flexibility and accuracy.
(2) The operation of the main motor is humanized and has protective functions
The main motor adopts a humanized design, running smoothly and with low noise, creating a relatively comfortable working environment for operators. At the same time, the motor has comprehensive protection functions. When the equipment experiences abnormal situations such as overload or overheating, it can automatically trigger the protection mechanism, stop running, avoid motor burnout and other serious faults, ensure safe and reliable operation of the equipment, and extend the overall service life of the equipment.
(3) Glue shortage alarm function
Built in high-precision position sensor, real-time monitoring of the position of the pressure plate in the rubber drum. Once the glue level is too low or the glue bucket is about to be emptied, the sensor immediately triggers the glue shortage alarm function, promptly notifying the operator to replenish the glue, avoiding production interruption caused by glue shortage, ensuring the continuity of the production process, and improving production efficiency.
