Description

Technical Field

[0001] The utility model relates to the technical field of raw material melting devices, in particular to a hot melt adhesive raw material melting device. Background Art

[0002] The hot melt adhesive raw material melting device is a device used to heat and melt solid hot melt adhesive particles or block raw materials into a liquid state, so as to facilitate subsequent applications such as coating, bonding or injection. Publication No. CN211586519U discloses a particle melting device for hot melt adhesive production, including a melting box and a fixed base, a feeding funnel is connected to one side of the top of the melting box, a servo motor is installed at the middle position of the top of the melting box, the output end of the servo motor is connected to a rotating shaft through a coupling, the rotating shaft passes through the top of the melting box and is rotatably connected to the melting box, a stirring rod is welded on the circumference of the rotating shaft, and a heat conducting plate is arranged below the stirring rod at the bottom of the melting box. The particle melting device heats and melts the raw material particles through a heating plate, and drives a stirring rod to rotate to stir the raw material particles, thereby increasing the melting speed and making the melting more complete. However, in actual use, the device needs to wait until all the internal particles are melted before receiving the material, otherwise incompletely melted particles will mix in and escape, and the flexibility is low. Moreover, if only a filter plate is added on the inside to intercept the unmelted particles, the material discharge efficiency may be slow, which needs to be improved. Utility Model Content

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, by arranging mounting rods, sliding rods, filter plates, pads, springs, corrugated plates, transverse plates, positioning rods, striking heads, tension springs, and arc-shaped plates, solid-liquid separation of hot melt adhesive can be achieved during operation, so that the hot melt adhesive can be taken as needed, which improves flexibility. During the operation of the motor, the filter plate will be driven to slide up and down along the sliding rod in a small range, so that the efficiency of discharging the melted hot melt adhesive can be effectively accelerated, and no extra power source is required, thereby reducing unnecessary capital expenditure.

[0027] Working principle: When working, firstly, the hot melt adhesive particles are put into the melting tank 1 from the feed bin 3, then the heating plate 2 is started to drive the temperature inside the melting tank 1 to rise, and under the action of temperature and gravity, the hot melt adhesive melted into liquid will flow downward through the filter plate 8, then the motor 4 is started and the mounting rod 5 is driven to rotate, during which the stirring plate 6 is driven to rotate, and then the hot melt adhesive particles can be stirred to improve the melting efficiency, and the mounting rod 5 will drive the corrugated plate 11 to rotate at the same time, and the positioning rod 13 will be pushed upward under the action of the corrugation of the corrugated plate 11 and the arc surface of the arc plate 16, so as to drive the striking head 1 4 hits the filter plate 8 and drives the filter plate 8 to slide slightly along the slide bar 7.
