This article will delve into the principles, application fields, functional characteristics and operating methods of hot melt glue machines to fully understand this indispensable equipment in modern industry.
1. The principle of hot melt glue machine
The principle of the hot melt glue machine is based on the characteristics of hot melt glue. Hot melt glue is a solid adhesive that can become a fluid state after being heated, and then completes the bonding after cooling and solidification. The main components of a hot melt adhesive machine include heating system, pressure system and coating system.
Heating system
The heating system is the core part of the hot melt adhesive machine and usually consists of an electric heater, heating tube and temperature controller. The electric heater and heating tube are responsible for providing sufficient heat to heat the hot melt adhesive to the temperature required for its flow state. The thermostat is used to accurately control the temperature to ensure that the hot melt adhesive always maintains proper fluidity during use.
pressure system
The pressure system controls the pressure to ensure proper fluidity of the hot melt adhesive during coating or spraying. Usually, the pressure system consists of a pneumatic or hydraulic system, and the flow rate and coating thickness of the hot melt adhesive are controlled by adjusting the system pressure.
Coating system
The coating system is responsible for evenly coating the hot melt adhesive on the surface to be bonded. This is usually accomplished with a coating roller, coating nozzle or coating knife. The design of the coating system affects the uniformity and adhesion performance of the hot melt adhesive and therefore plays an important role in the design of the hot melt adhesive machine.

3. Functional characteristics of hot melt glue machine
Hot melt glue machine. It has many unique features that make it widely used in various industries:
Fast cure . The hot melt glue used by the hot melt glue machine flows quickly after heating, and then solidifies quickly during the cooling process.
Environmental friendly . Compared with traditional solvent-based glue, hot melt glue does not require the use of harmful solvents, reducing environmental pollution.
Sturdy and solid . After curing, hot melt adhesive forms a strong and strong bond that can withstand a certain amount of tension and vibration. Therefore, it performs well in applications that require higher bonding strength.
Precise coating . The hot melt adhesive machine can achieve precise coating of hot melt adhesive through precise temperature and pressure control. Therefore, hot melt adhesive machines are suitable for applications that require higher coating thickness.
Diverse coating methods . Hot melt adhesive machines have a variety of coating methods, including roller coating, spray coating, blade coating, etc. Therefore, hot melt glue machines can adapt to different production needs.
4. How to operate the hot melt glue machine
Correct operation method is the key to ensure the normal operation of the hot melt adhesive machine and obtain the best results. The following are the basic operating steps of a general hot melt adhesive machine:
1) Turn on the power: First, connect the power supply of the hot melt glue machine to the power socket and make sure the power switch is turned off.
2) Add hot melt glue: Open the hot glue tank of the hot melt glue machine and add hot melt adhesive strips or particles into the tank. Take care to ensure you select the appropriate type and specification of hot melt adhesive to meet your specific production needs.
3) Set temperature: Set the operating temperature of the hot melt adhesive machine through the thermostat. According to the type of hot melt adhesive used and production requirements, adjust the temperature to ensure that the hot melt adhesive can reach a flowing state.
4) Start preheating: Close the hot glue tank cover and start the preheating function of the hot melt glue machine. Wait for a while until the hot melt glue completely melts and reaches the set operating temperature.
5) Adjust pressure: According to actual needs, adjust the pressure system of the hot melt adhesive machine to ensure that the hot melt adhesive has appropriate fluidity when coating or spraying.
6) Start coating: Once the hot melt adhesive reaches the appropriate temperature and pressure, the coating operation can begin. Use coating systems such as coating rollers, nozzles or coating knives to operate according to specific process requirements.
10) Turn off the machine: When the production task is completed, turn off the power switch of the hot melt adhesive machine and wait for the machine to cool down. Before cleaning and performing maintenance, make sure the melter is completely out of service.
5. Maintenance and maintenance
In order to ensure the long-term stable operation of the hot melt adhesive machine, regular maintenance and upkeep is crucial. Here are some suggestions:
Clean the hot glue tank regularly and remove residual hot melt glue to ensure that the newly added hot melt glue is not contaminated. This helps maintain the pure performance of the hot melt adhesive.
Regularly check the electric heater, heating tubes and thermostat of the heating system to ensure that they are working properly. If there is any abnormality, replace or repair it in time to avoid affecting the stable performance of the hot melt adhesive machine.
Regularly check the pressure system of the hot melt adhesive machine to ensure that the pipes, valves and sensors of the pneumatic or hydraulic system are in good condition. Adjust pressure to meet different process requirements.
For moving parts such as rollers and nozzles in the coating system, lubricate them regularly to reduce friction and improve smooth operation.
Carry out regular maintenance work according to the maintenance cycle in the hot melt adhesive machine's user manual. This may include replacing consumable parts, cleaning filters, checking electrical circuits, etc.
