Serious drawing of hot melt adhesive, slowing down the efficiency of packaging assembly line? This way, the efficiency doubles!

In the packaging assembly line operation, many enterprises encounter serious problems of overheating adhesive wire drawing: after spraying, the adhesive wire keeps winding around the equipment and sticking products, which not only affects the cleanliness of the packaging appearance, but also requires frequent shutdowns to clean the adhesive wire, seriously slowing down the efficiency of the assembly line, increasing adhesive consumption and labor costs.

Hot melt adhesive wire drawing is not without solution, the core is to identify the root cause, solve it targetedly, and more importantly, choose the right specialized hot melt adhesive that is suitable for the packaging assembly line. Today, we will help you completely bid farewell to the problem of wire drawing and make the packaging assembly line run efficiently from three aspects: cause analysis, quick solution, and high-quality adhesive recommendation!

1、 Is the hot melt adhesive drawing serious? 3 core reasons

1. Improper temperature control (the most common reason)
   Each hot melt adhesive has a fixed optimal melting temperature range (commonly 160-180 ℃ for packaging adhesive).
   Low temperature: Insufficient melting of colloids, high viscosity, poor flowability, like viscous syrup, easy to pull out long filaments when lifting or moving the gun;
   Excessive temperature: Excessive melting of colloids, damage to cohesion, and the formation of fine flying fibers may also lead to colloid carbonization, impurities, and intensified wire drawing;
   Environmental impact: In winter, the temperature is low, and the colloid cools quickly, causing premature solidification at the nozzle and more severe wire drawing.
2. The adhesive performance does not match the assembly line
   High viscosity: poor fluidity in the molten state, difficult to break the adhesive, and obvious drawing;
   Excessive cohesion: Colloidal molecules have strong intermolecular forces, making it difficult to break quickly and easily forming continuous gel fibers after pulling and pulling;
   Unreasonable curing time: The curing is too slow, and the gel continues to flow and draw after spraying; If the solidification is too fast and the colloid solidifies before spreading, it can also cause wire drawing.
3. Inadequate operation and maintenance of equipment
   Improper spraying distance: The nozzle is too far away from the adhered object, causing excessive stretching of the glue during spraying, resulting in wire drawing;
   Insufficient equipment cleaning: nozzle blockage, residual carbide glue, uneven glue dispensing, resulting in wire drawing;
   Abnormal pressure setting: The pressure of the glue machine is too high, resulting in excessive extrusion of glue and easy wire drawing after accumulation.

2、 Quickly solve wire drawing problems! 4 Practical Methods

1. Accurate temperature control
   Referring to the adhesive parameters, set the temperature at the recommended midpoint, and increase it by 10-20 ℃ in winter; Avoid prolonged high temperature heating to prevent colloid aging and carbonization.
2. Optimize device operation
   Adjust the distance between the nozzle and the adhesive to ensure stable dispensing; Regularly clean the nozzle and hose, and remove residual impurities; Reasonably adjust the pressure of the glue machine and control the glue output to be moderate.
3. Standardize the usage process
   Add a small amount of glue multiple times to avoid clumping of the glue; Close the nozzle promptly after shutdown to prevent glue from overflowing and carbonizing; Keep equipment insulated in winter to reduce the impact of environmental temperature on colloids.
4. Replace with high-quality hot melt adhesive that is compatible
   If the drawing problem is still not solved after adjusting the temperature and equipment, the core solution is to replace the glue! Choose specialized packaging hot melt adhesive with good fluidity, moderate cohesion, and fast curing to eliminate wire drawing from the root.
