Uneven dispensing of hot melt adhesive machine? Saipu teaches you one easy trick to handle, it's super easy to use and adjust at the same time!

On the production line, uneven glue output from the hot melt glue machine is definitely a headache - the amount of glue is too much or too little, which either leads to weak adhesion of the product, overflow of glue and waste of raw materials, and even affects subsequent processes, slowing down production progress. Many customers encounter this situation and their first reaction is to seek help from a repairman or suspect that the machine has a major problem. Actually, there's no need to panic! Dongguan Saipu Machinery Manufacturing Co., Ltd. has been deeply involved in the field of hot melt glue machine for many years, and has long understood the core key for everyone: the scraper plate of the hot melt glue machine is kept parallel to the drum, and the glue naturally comes out evenly. More importantly, we have designed a super simple adjustment plan for our customers, which allows them to see the effect while working without stopping or using complex tools. Even beginners can easily get started!

Core principle: Parallel means uniform, the key to precise control of glue

The adhesive effect of the hot melt glue machine depends on the coordination between the scraper plate and the roller. When the two are completely parallel, the hot melt adhesive passes through the gap between the roller and the scraper plate, and is subjected to uniform pressure and stable flow rate. The final adhesive layer applied to the product will be uniform in thickness, smooth and even. On the contrary, if there is a tilt between the scraper plate and the drum, and the gap is wide or narrow, the amount of glue will naturally be biased - more glue will be dispensed in areas with wide gaps, and less glue will be dispensed in areas with narrow gaps. This is the core reason for uneven glue dispensing.

Practical guide: Adjust while working, with real-time results

The adhesive effect of the hot melt glue machine depends on the coordination between the scraper plate and the roller. When the two are completely parallel, the hot melt adhesive passes through the gap between the roller and the scraper plate, and is subjected to uniform pressure and stable flow rate. The final adhesive layer applied to the product will be uniform in thickness, smooth and even. On the contrary, if there is a tilt between the scraper plate and the drum, and the gap is wide or narrow, the amount of glue will naturally be biased - more glue will be dispensed in areas with wide gaps, and less glue will be dispensed in areas with narrow gaps. This is the core reason for uneven glue dispensing.

1. Keep the machine running normally: There is no need to stop the machine, let the hot melt adhesive machine work according to the normal production rhythm, and ensure that the hot melt adhesive is in a stable melting state.

2. Observe the adhesive state: Carefully inspect the adhesive layer applied by the roller, identify areas with excessive or insufficient adhesive, and clarify the direction of adjustment.

3. Fine tune the scraper plate: Find the adjustment screw on the scraper plate, gently rotate it according to the glue dispensing situation - on the side with more glue dispensing, slightly loosen the screw to reduce the gap and then fix it; The side with less adhesive will increase the gap.

4. Confirm the effect and fix it: During the adjustment process, observe the changes in the adhesive in real time until the adhesive layer evenly covers the drum and the amount of adhesive applied to the product is stable and consistent. Then tighten and fix the adjustment screw on top, and the adjustment is complete!

Advantages of Maolong: Reducing operational difficulty from the design source

Why is it so easy to adjust Saipu's hot melt adhesive machine? Because we always design from the customer's production perspective:

Optimize the adjustment structure: adopting a precise knob style adjustment design, the adjustment stroke is clear, the force is easy to control, and excessive adjustment is avoided.

Visual operation: The fitting area between the scraper plate and the roller is unobstructed, and the gap changes and adhesive effect can be clearly observed during adjustment, without blind debugging.

Stable and durable: After adjustment, it is firmly fixed and not easily displaced due to machine vibration, ensuring long-term stable glue dispensing. Uniform dispensing is the foundation for ensuring product quality and the key to improving production efficiency and reducing costs.

Saipu Electromechanical always adheres to the design concept of "simple operation, stable and efficient", so that every hot melt adhesive machine can adapt to the actual production needs of customers and solve pain points and problems in production. If your production line also encounters the problem of uneven glue output from the hot melt glue machine, you may want to try the above method!
