Description

Hot fix rhinestone gluing equipment

Technical Field

The invention belongs to the technical field of hot-fix rhinestone upper base glue, and particularly relates to hot-fix rhinestone gluing equipment.

Background

The hot-fix rhinestone is similar to the traditional diamond in appearance, the side surface of the hot-fix rhinestone is provided with a plurality of edge surfaces, and the areas of two end surfaces are one large and one small; at present, the production link of the hot-fix rhinestone is complex, and the technological processes are different; however, as the final application of the rhinestone, a layer of hot melt adhesive bottom is arranged on the bottom surface with a larger rhinestone area. The adhesive is adhered to a target material in a pressing mode in the application links of clothes, cases, belts, mobile phone shells and the like. Therefore, whether the primer of the crystal hot drill is uniform or not is related to the quality of the hot drill; in the prior art, a manual gluing mode is basically adopted, and in the manual gluing, the uniformity of glue powder at the bottom of the crystal hot-melting rhinestone cannot be guaranteed due to manual glue spreading, so that the uniformity of the base glue after hot melting is different, and the quality of the crystal hot-melting rhinestone is reduced; meanwhile, the processing efficiency is reduced by adopting a manual powder scattering mode; a few devices realize automatic gluing of the rhinestones, the devices have a good foot-feeding effect on rhinestones of a single specification, but are difficult to adapt to when the rhinestones of different specifications are replaced and processed, and the device limitation is large.
