An embodiment of the present invention provides a hot melt adhesive sorting and feeding device, as shown in fig. 1, which includes a material sieving assembly and an air supply assembly, wherein the material sieving assembly includes a material sieving box 100 and a vibration assembly disposed at the bottom of the material sieving box 100 and driving the material sieving box 100 to vibrate, and the material sieving box 100 may be rectangular and is used for sieving materials. The sieve material box 100 is obliquely arranged relative to the horizontal direction, one end of the sieve material box 100 in the length direction is higher than the other end of the sieve material box in the length direction, a filter screen is arranged in the sieve material box 100, and the filter screen can be parallel to the length direction of the sieve material box 100 and is also obliquely arranged relative to the horizontal direction. The filter screen may be located in a central position within sieve box 100, thereby dividing the interior space of sieve box 100 into a first sieve material chamber and a second sieve material chamber located above the first sieve material chamber. The filter screen is densely distributed with meshes with preset sizes so as to screen out unqualified hot melt adhesive particles with the sizes smaller than the preset sizes.

The feed inlet 110 that feeds through with first sieve material chamber is provided with in the upper end (the higher one end relatively of height) of sieve workbin 100, and the hot melt adhesive granule that treats to select separately enters into sieve workbin 100 from feed inlet 110, and the filter screen can filter the unqualified hot melt adhesive granule of size, makes the defective work fall into second sieve material chamber, and the non-defective products hot melt adhesive then removes along the filter screen.
