Description

Hot melt adhesive quick melting device Technical Field The utility model relates to the technical field of hot melt adhesive quick melting, in particular to a hot melt adhesive quick melting device. Background The hot melt adhesive is a thermoplastic adhesive which is solid at room temperature, can be melted into liquid state when heated to a certain temperature, and can be quickly solidified after being cooled, thereby realizing the bonding function. However, in the prior art, the hot melt adhesive heating device is generally simple in structure, the heating device is arranged at the bottom, so that the heat transfer path is single, the whole heating speed of the hot melt adhesive is low, a large amount of time is required to be consumed for machine preheating, the condition of uneven heating easily occurs, the hot melt adhesive with poor fluidity is caused to agglomerate at dead corners in the box body, the hot melt adhesive is solid at normal temperature and has a certain shape and size, when the hot melt adhesive with large blocks is heated, heat can be transferred from the surface to the inside gradually, the melting temperature of the internal hot melt adhesive can be reached only by long time, the heat conducting property of the hot melt adhesive is relatively poor, and the problem of low melting speed is further aggravated, so that the hot melt adhesive quick melting device is required. Disclosure of utility model The utility model aims to provide a hot melt adhesive quick melting device, which solves the problems of low heating speed and large heat conduction difficulty of hot melt adhesives in the prior art. The hot melt adhesive quick melting device comprises a working box, a joint for discharging the hot melt adhesive is arranged on the side wall of the working box, a top plate with a sealing function is arranged above the working box, a guide box for conveying the hot melt adhesive through a conveying pipe connection is arranged above the working box, a crushing box for pouring the hot melt adhesive is arranged above the guide box, and a positive crushing roller and a negative crushing roller for crushing the hot melt adhesive are arranged inside the crushing box. Preferably, one end of the positive crushing roller is provided with a driven gear at the outer side of the crushing box, the outer wall of the driven gear is provided with a driving gear connected with one end of the reverse crushing roller, the outer wall of the crushing box is connected with a sealing shell, and the outer wall of the sealing shell is connected with a rotating motor for driving the driving gear to rotate.
