Welcome to this article, which is an in-depth guide to gluing machine, Before you buy a new gluing machine, check out our guide that covers everything you should consider to find the best machine for you
1. What is a gluing machine?
Glue machine is also known as Glue Coating Machine, Glue Scraping Machine, Automatic Glue Spraying Machine, and so on. Gluing machine is the mechanical equipment for applying liquid adhesive to fabric, cardboard, or leather. Currently, there are many kinds of glue, such as drum glue, double action glue, double stick glue, lifting glue, and so on. Applicators use air pressure to spray a liquid, such as glue or paint, on the desired product. The device adopts three axes linkage, operates automatically, and has a computer program control path spraying. Spray thickness and spray time can be set, and it is easy to operate.
2. What types of gluing machines are there? How do they work?
There are three types of gluing machines below:
1) Double roller gluing machine
The double-roll adhesive machine is made up of the top and bottom adhesive roll and the adhesive box. The veneer is in contact with the adhesive roll when it goes between the two adhesive rolls so that the adhesive on the adhesive roll covers the top and bottom surfaces of the veneer. The amount of adhesive applied is mainly determined by adjusting the clearance of the top and bottom rubber rolls and the pressure of the top rubber roll. The thicker and narrower the veneer, the higher the pressure of rolling on the veneer, and the less the glue applied; Otherwise, the greater the amount of glue applied. The shape and the number of slots on the roll also affect the amount of adhesive applied. The glue liquid level in the glue tank should be 1/3 of that of the bottom glue roll. Too big or too small will influence the amount of glue applied.
2) Three-roll gluer
Three-roll of glue is added to the top or bottom of the rubber roll. The bonding quantity is decided by the gap between the adhesive roll and the adhesive roll. Next to the top adhesive roll, there is a rubber pressing roll, the glue pump delivers the glue by the rubber tube, and the groove formed between the glue-applying roll and the rubber extruding roll is used to store the glue. The adhesive output is not influenced by the liquid level of the glue tank. Although the adhesive quality of the three rollers is good, it can only control the bonding quantity of one side, so it is not widely used.
3) Four-roll gluer
Four-roll glue is added to the top and bottom of the glue roll to control the amount of adhesive on the board and bottom surface. Compared with the rubber coating roll, the linear velocity is reduced by 15% ~ 20%, and the gap with the rubber coating roll can be adjusted to guarantee the thickness of the top and bottom. The top and bottom rubber rolls supply glue simultaneously and do not interfere with each other, so it is easy to produce glue when sticking. It is a kind of widely used gluing equipment.
There are two arrangements of extrusion rollers for a four-roll gluer. Firstly, the adhesive roller is arranged on the two sides of the adhesive roll, and the glue pump supplies the glue through the rubber pipe. The other is that the top and bottom rubber rolls are placed on the feed side of the rubber roll, the adhesive is applied to the top rubber roll by the glue pump, and the glue is supplied to the bottom rubber roll by the glue tank. Because of the different arrangements of the rollers and the bonding method, they have different functions. The former can be applied uniformly, which can save glue, and the latter can be used to produce high efficiency.
3. What are the functions of the gluing machine?
The gluing machine is mainly used in the engine oil pan, cylinder head, upper cover, flywheel housing, window glass, etc., and can apply sealant evenly on the workpiece according to the planned trajectory. The gluing machine can achieve quantitative, uniform, and accurate gluing according to the predetermined track, and the gluing line speed can be adjusted in the range of 0~6m/min. A visual system can be added to realize automatic position confirmation before gluing and quality confirmation after gluing.
The moving parts of the gluing machine can use a mechanical arm or a robot. Adopting numerical control system control, it is very simple and convenient to change the trajectory. It can be designed as a multi-station operation to realize a common gluing machine for various workpieces. The glue applicator has the functions of automatic cleaning of the glue head and anti-glue blocking. With an anti-intrusion detection system, safe and reliable.
4. What are the advantages of the gluing machine?
The operation of the gluing machine is very simple. Regular binding of materials can be started via the four buttons on the control box. Coding is so simple that a person who does not have coding or even a rudimentary computer skill will be able to do it on their own in just one or two days.
All products are identical and of high quality. Reduce the impact of staff on the quality and productivity of products. A worker can work on two machines. As a result, this machine is able to improve product quality and efficiency and reduce production costs.
5. How to use the gluing machine?
There are some steps below:
1) Encoding
Corresponding program product. Once the glue head follows the bonding line, the machine will automatically record the bonding line, and then the program will be generated automatically. It’s very easy for us. People who don’t have the ability to code or even have basic computer skills will be able to do it on their own in just one or two days.
2) Adjust the glue seam
You can use needles with other holes or change the air pressure inside the cartridge. Glue joints should be kept to a minimum.
3) Mass production
In actual production, regular bonding can be initiated by the four buttons on the control frame. “Run”, “Stop”, “Reset” or “Scram”.
6. What are the uses of the glue machine?
It is mainly used in toys (bonding, fastening, wiring, insulation); airtight packing; leather bags; purses. Small electrical appliances, wires, connectors, connectors; sound systems, photo frames; identifying tags; hardware fixings; small paper bonding; small accessories, crafts, hairpins, water polo, etc. Fixing, bonding, insulating, and other manual or semiautomatic bonding are required.
7. Conclusion
The above is all about the introduction of the “Gluing Machine”. Hope the above information can help you.
