Technical Field

The invention relates to glue spraying equipment, in particular to a combined glue gun and a glue spraying device.

Background

In the production and manufacturing process, the processes of glue dispensing and glue applying are still unavoidable or completely replaced by automatic equipment. In order to prevent the phenomena of looseness, poor oxidation contact and the like caused by vibration generated in the production process of accessories, components and the like, finished product transportation and field use, and the requirements of insulation sealing glue protection and the like, the production requirements of products still need to be met by glue dispensing and gluing processes, wherein a plurality of processes are limited to manual gluing processes.

The manual gluing is suitable for the process requirements of small batch, small range, complex angle direction, gap contact and the like. At present, manual tools or semi-automatic auxiliary tools have inconvenience and limitations, and the method specifically comprises the following steps:

1. when the single hose adhesive, the silica gel and the like are used, the diameter of the outlet of the rubber cap is required to be cut according to the size of the dispensing area and the volume. When the diameter is too small, the control of the squeezing pressure of the rubber tube root is difficult, the rubber tube is easy to fatigue and shake, and the phenomena of uneven gluing and the like are generated. The diameter opening is too large, the glue output quantity is increased, the glue beating speed is difficult to control, and unnecessary waste or a non-glue beating area is covered. And the corrugated position is repeatedly extruded by the hose packaging aluminum foil, so that the rear end is easy to leak glue, and the whole rubber tube cannot be used.

2. Although the force of the syringe type adhesive or trigger type glue gun is controllable or labor-saving, the rear end holding still influences the glue beating action, and the accuracy is continuously reduced. If the user pulls or pushes the handle for a long time, the hand still can be tired, the precision is reduced, and the persistence is poor. And the packaging cost of the syringe is increased, or the filling is troublesome to cause the pollution of production environment.

3. The existing pneumatic glue applying method still pushes a needle cylinder type push rod or a piston column through compressed air power, and the structure limitation holding mode is generally a rear-end gun type. The volume is too large, the holding is inconvenient, the gluing position cannot be accurately and finely controlled, and the syringe type filling cost is high and the syringe type filling cannot be reused.

4. The AB type adhesive glue gun is special for glue guns, has no mixing device or simple mixing glue heads, and adopts a manual or simple pneumatic mode. The double-tube is still pushed manually by a needle cylinder type push rod or a trigger type, and the resistance is increased by the simple mixing device, so that the labor is wasted and the mixture is not uniform. The aforementioned problems still exist in pneumatic operation, and the mixing device cannot operate independently, and only mixes by means of the thrust generated when the adhesive itself overflows, and the mixing is not uniform.
