A hot melt jet dispenser is a mechanical device used to melt a solid state of hot melt adhesive and spray it in liquid form onto the product that needs to be bonded. This equipment is widely used in automobiles, packaging, handicrafts and other industries that require adhesive technology.
The hot melt adhesive jetting machine has an integrated design of heating control, pressurization function, liquid delivery and spraying function, which can spray hot melt adhesive into leather, paper, shoe materials, insoles and other products that need to be bonded in different shapes such as dots, strips, and fogs. Depending on the need, the equipment can be equipped with different nozzles and outlets to meet different production needs.
When using a hot melt jet dispenser, care needs to be taken to control the heating temperature and pressure to ensure that the hot melt adhesive can be fully melted and evenly sprayed. At the same time, the appropriate type and model of hot melt adhesive should be selected according to the need, and attention should be paid to operation safety and environmental protection.
At present, the hot melt adhesive jet dispensing machine manufacturers have Hongdahui Technology. Founded in 2013, Hongdahui Technology Co., Ltd. is a high-tech enterprise that provides precision dispensing, coating, gluing, industrial dispensing equipment, auxiliary material assembly equipment, plasma cleaning equipment and other equipment in the industry.
The working principle of the hot melt adhesive jet dispenser is to heat and melt the solid hot melt adhesive, spray the melted glue onto the product to be bonded by pressure, and realize bonding after the glue cools and solidifies.
Specifically, a hot melt adhesive jetting dispenser uses a heating system to heat a solid hot melt adhesive to a molten state, and the spraying system accurately sprays the melted glue onto the product to be bonded. A spraying system typically consists of a nozzle that creates a fine flow of glue and a pressure system that ejects the glue out of the nozzle by applying pressure.
In hot melt jet dispensers, the design and control of the heating system and spraying system are critical. The heating system needs to be able to evenly heat the hot melt adhesive to the appropriate temperature to ensure the viscosity and spraying effect of the glue. Spraying systems need to precisely control the amount and speed of spraying to ensure that the glue evenly covers the area to be bonded and that the bond is good.
In addition, the heating and spraying systems of hot melt jet dispensers are often modular, allowing users to swap out different modules as needed to accommodate different types and specifications of bonding needs.

4.High degree of automation: The hot melt adhesive jet dispensing machine can be integrated with the production line automation to achieve automated production and improve production efficiency and product quality.
5.Environmental protection and safety: The hot melt adhesive jet dispensing machine adopts environmentally friendly materials and will not produce harmful gases and wastewater, which is in line with the current concept of green environmental protection. At the same time, the safety performance of the equipment is high, which can effectively prevent safety accidents such as glue curing and clogging needles.
6.Wide range of application: Hot melt adhesive jetting machine is suitable for various industries that need to be bonded, such as automotive, packaging, clothing, etc., with a wide range of applications.
In a word, the hot melt adhesive jetting machine has the advantages of fast curing, high viscosity, easy operation, high degree of automation, environmental protection and safety, and a wide range of applications, which can greatly improve production efficiency and product quality.
1.Preparation: Check that the power and air supply of the hot melt jet dispenser are working properly, and make sure that the equipment is well grounded. Check whether the storage container of glue or sealant is sufficient, and replenish it in time if it is insufficient. Clean the work area of the bench and dispenser to ensure that it is free of debris and dust.
2.Adjust parameters: Adjust the parameters of the hot melt spray dispenser according to the product requirements and process requirements, such as dispensing speed, dispensing volume, nozzle moving position, etc.
3.Preheating: After the rated voltage of the machine is turned on, turn on the power switch of the heater, and the power indicator of the heater will light up. Adjust the temperature controller of the storage tank between 130-140 and the temperature controller of the gluing roller between 140-150. The above temperature is for reference only, and the actual melting point of the hot melt adhesive shall prevail. At this point, the heater preheating procedure is complete.
4.Start the motor: After the hot melt adhesive in the glue tank has melted after 30 minutes of preheating, the motor start indicator light will be on, and the motor power switch can be turned on, and then the motor speed adjustment knob can be adjusted to the desired working speed. If the motor fails to turn, wait until the hot melt adhesive is completely melted before turning it on. At this point, the starting motor is complete.
5.Adjust the glue volume and thickness: adjust the glue amount adjustment knob, thicken in the clockwise direction and thinn in the counterclockwise direction, and adjust it to the required glue amount.
6.Debugging the nozzle: Align the nozzle of the hot melt dispenser with the test board, press the glue spraying button, and observe the glue spraying situation. If the glue is sprayed evenly and the glue is smooth, it means that the hot melt dispenser is successfully commissioned. If the glue is dispensed unevenly or the glue is not smooth, the temperature needs to be readjusted or the nozzle needs to be cleaned.
7.Shutdown sequence and method: 5-10 minutes before the shutdown stops working, please turn off the power switch of the heater first, so that the temperature of the rubber roller and the rubber storage tank is reduced, so as to prevent the carbonization of the hot melt adhesive on the rubber roller. When the heater power switch is turned off for 5-10 minutes, the temperature drops, you can adjust the motor speed adjustment button to zero, and then turn off the motor power switch. Finally, turn off the power of the input machine to complete the shutdown procedure.
It should be noted that during operation and commissioning, it is necessary to follow the safety operation procedures to ensure personal safety and equipment safety. At the same time, the equipment should be maintained regularly to ensure the normal operation and service life of the equipment.
