Generally, after large materials are sprayed and pasted by a glue spraying machine, they still need to be segmented into small material assemblies by another cutting machine, which reduces production efficiency and increases labor cost. Therefore, in order to improve the deficiencies of the existing glue spraying machine technology, the utility model provides a glue spraying device which integrates gas source treatment, glue spraying, cutting and brake functions, has the advantages of compact structure, simple operation, stable performance and the like. By accurately controlling the working parameters of each module, efficient and accurate glue spraying and bonding operations can be realized. SUMMARY

[0004] To achieve the above purpose, the utility model adopts the technical scheme of a glue spraying device, which comprises a gas source treatment assembly connected to a glue spraying system. The rated gas source pressure is used to connect the compressed air purified and filtered for operation to the glue machine inlet through the gas path change device, so as to reduce the influence of water, oil and other pollutants on the aging of the material and prolong the service life of the device body parts.

[0005] The glue spraying system comprises a glue machine and a glue spraying device, and the glue machine is connected to the glue spraying device through a glue pipe. The glue spraying device is provided with a heating device, the heating device is provided with a swing shaft, and the swing shaft is provided with a bottom plate and a rotating plate. The heating device is also provided with a protective cover and a hot air gun, and the hot air gun is provided with a heating pipe with an inlet core. The bottom plate and the rotating plate pass through two hot air guns. By adjusting the angle or position of the rotating plate, the glue spraying range and angle of the nozzle can be accurately controlled.

[0006] The hot air gun is provided with a connector below, the connector is provided with a gasket below, and the gasket is provided with a nozzle connected below. The gasket can increase the stability of the connection and prevent glue leakage. The side of the hot air gun nozzle beside the protective cover has an opening to optimize the spraying direction of the glue.

[0007] The adhesive spraying system is connected to the cutting system and the braking system via a three-way air valve. The cutting system is equipped with a cutting cylinder; compressed air acts on the piston of the cylinder to generate thrust, causing the cutter to perform the cutting operation. The cutting cylinder has guards that fix the material cutting position and control the distance between the cutter and the material, preventing over- or under-cutting.

[0008] The braking system includes a belt guiding device, a double-sided synchronous belt, and a synchronous belt tensioning device. The belt braking device comprises bearings, a synchronous belt, and synchronous pulleys. The bearings are fixed to the synchronous pulleys; the rotation of the pulleys drives the bearings to rotate. The synchronous belt wraps around two bearings spaced a distance apart. The simultaneous rotation of the two bearings drives the synchronous belt transmission. The distance between the two belt braking devices is less than the width of the material by 1-2 mm, allowing the stacked materials to separate during transmission into the machine. The double-sided synchronous belt is wound around the bearings at the same position on both belt braking devices and the synchronous belt tensioner. Before adjusting the gap distance between materials of different sizes passing through the belt braking devices, the double-sided synchronous belt is first loosened, and then the tensioner is used to relax the tension.
