Hot melt glue dispensing machine
1. Hot melt glue dispensing machine working Principle
The hot melt glue dispensing machine heats the solid hot melt glue to a molten state through an electric heating device, turning it into a liquid state. Subsequently, the liquid glue is pushed to the dispensing head through air pressure, mechanical extrusion, etc., and finally the glue amount and dispensing position are accurately controlled by the control system to achieve precise dispensing. The hot melt glue solidifies quickly after cooling to form a strong bonding effect.
2. Hot melt glue dispensing machine Components
1. Heating system: including heater and temperature control system, used to heat the hot melt glue to the required temperature. The efficient heating system can ensure that the hot melt glue melts quickly in a short time.
2. Dispensing head: The dispensing head is a component that accurately applies the molten glue to the target position. The design of the dispensing head determines the accuracy and uniformity of the dispensing.
3. Glue delivery system: including glue guns, hoses, etc., used to deliver molten hot melt glue. Air pressure or mechanical extrusion is often used to drive the delivery of hot melt glue.
4. Control system: including program controllers and sensors, which control various links of the dispensing process through preset parameters, such as dispensing speed, time and glue amount.
5. Glue storage device: used to store solid hot melt adhesive and ensure that it can be quickly heated and transported when needed.
3. Hot melt glue dispensing machine Classification
According to different application requirements and technical characteristics, hot melt glue dispensing machines can be divided into the following categories:
1. Manual hot melt glue dispensing machine: simple operation, suitable for small-scale production or manual operation.
2. Semi-automatic hot melt glue dispensing machine: combines manual and automatic functions, suitable for small and medium-scale production.
3. Fully automatic hot melt glue dispensing machine: fully automated, suitable for large-scale industrial production, can significantly improve production efficiency.
4. Desktop hot melt glue dispensing machine: small size, suitable for laboratories and small production lines.
5. Portable hot melt glue dispensing machine: light size, suitable for on-site maintenance and small-scale operations.
4、Hot melt glue dispensing machine Application fields
1. Electronic industry: used for fixing electronic components, encapsulating circuit boards, bonding heat sinks, etc.
2. Automobile manufacturing: used for bonding and sealing of components such as headlights, doors, and interiors.
3. Packaging industry: used for packaging and bonding of cartons, gift boxes, packaging bags, etc.
4. Furniture manufacturing: used for furniture assembly and bonding of decorative parts.
5. Crafts production: used for bonding various decorative materials in crafts and gift making.
5、Hot melt glue dispensing machine Advantages and disadvantages
1. Advantages:
Fast curing: hot melt adhesive cools quickly and has high bonding efficiency.
Easy operation: the equipment is simple to operate, easy to master and use.
Environmentally friendly and safe: hot melt adhesive has no solvent, does not produce harmful gases, and is safe and environmentally friendly to use.
Low cost: the equipment is easy to maintain, has low operating costs, and is suitable for large-scale production.
2. Disadvantages:
Poor temperature resistance: hot melt adhesive is sensitive to high temperatures and has poor temperature resistance.
Limited initial adhesion: in some cases, the initial adhesion may be insufficient and requires a certain amount of curing time.
Limited scope of application: not suitable for all materials, especially in some high temperature environments or occasions with high-strength bonding requirements.
6、 Hot melt glue dispensing machine Operation precautions
1. Temperature control: strictly control the heating temperature to avoid excessively high or low temperatures affecting the performance of the glue.
2. Regular maintenance: regularly check and maintain the equipment to ensure the normal operation of the heating system and the dispensing head.
3. Glue material selection: select the appropriate hot melt adhesive material according to the specific application requirements to ensure the bonding effect.
4. Safe operation: pay attention to safety during operation to avoid burns and equipment damage.
