The embodiment of the utility model provides a hot melt adhesive vibration screening device capable of uniformly distributing materials, which comprises a screening component and a feeding component 200, wherein the screening component comprises a screening box 100 and a vibration component which is arranged at the bottom of the screening box 100 and drives the screening box 100 to vibrate, and after the materials enter the screening box 100, the screening box 100 screens out good hot melt adhesive particles through vibration.

The feeding assembly 200 comprises a feeding pipe 250, a material transferring box 240, a material homogenizing box 220 and a feeding box 210, wherein the feeding pipe 250, the material transferring box 240, the material homogenizing box 220, the feeding box 210 and the material sieving box 100 are sequentially connected from top to bottom, and materials sequentially pass through the feeding pipe 250, the material transferring box 240, the material homogenizing box 220 and the feeding box 210 under the action of self gravity and finally enter the material sieving box 100. The material feeding pipe 250 transfers the material to the material transferring box 240, and since the material homogenizing box 220, the material feeding box 210 and the material sieving box 100 are all box-shaped structures, and the material feeding pipe 250 is a tubular structure, the material transferring box 240 transfers the material inputted from the material feeding pipe 250 to primarily disperse the material. The material-equalizing box 220 is provided with a material-dropping channel 221 which is inclined relative to the vertical direction, and the material will slide down along the inclined material-dropping channel. The plurality of homogenizers 222 are arranged on the inner wall of the blanking channel 221, when falling materials touch the homogenizers 222, the materials are dispersed through the plurality of homogenizers 222, and the materials finally entering the screening box 100 are uniformly dispersed, so that the materials can be rapidly screened, and the sorting efficiency is improved. Meanwhile, the condition of material accumulation is greatly reduced, unqualified products can be quickly screened out, and the screening rate of the unqualified products is also effectively improved.

In some embodiments, the homogenizer 222 comprises two homogenizing plates connected to each other at a predetermined angle (which can be determined by those skilled in the art based on the actual situation) such that the cross-sectional shapes of the two homogenizing plates are similar to a triangle. In the blanking direction, the two material homogenizing plates are gradually far away. When the material falls, the material touching the material homogenizer 222 slides down along the material homogenizing plate, and since the two material homogenizing plates are gradually far away from each other in the falling direction, the material is gradually dispersed in the falling process.

Furthermore, in the blanking direction, the width of the blanking channel 221 is gradually increased, so that the range in which the materials can be dispersed is enlarged, and the materials can be further dispersed more uniformly. As shown in FIG. 2, the blanking channel 221 can have an isosceles trapezoid cross-section with a small upper opening and a large lower opening.

Furthermore, the homogenizers 222 are arranged in a plurality of rows in the blanking direction, and the number of the homogenizers 222 in each row of the homogenizers is gradually increased in the blanking direction, and the number of the homogenizers 222 is also increased along with the increase of the width of the blanking channel 221, so that the materials are gradually dispersed.

In some embodiments, the blanking channel 221 forms an opening on the surface of the homogenizing box 220, the opening is covered with a cover plate 230, after the cover plate 230 is opened, the material in the blanking channel 221 can be observed, and when the material is jammed, and the like, the corresponding adjustment can be made. The cover plate 230 may be hinged to the homogenizing box 220 by a hinge 232, and a handle 231 is provided on an outer surface of the cover plate 230 to facilitate pulling the cover plate 230.

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.

Feed box 210 sets up in the upper end (the higher one end relatively of height) of sieve feed box 100, and the hot melt adhesive granule that treats to select separately enters into sieve feed box 100 from feed box 210 in, and the filter screen can filter the hot melt adhesive granule that the size is unqualified, makes the defective products fall into second sieve material chamber, and the non-defective products hot melt adhesive then removes along the filter screen. The lower extreme (the one end that highly is lower relatively) of sieve workbin 100 is provided with first discharging pipe 121 with first sieve material chamber intercommunication and the second discharging pipe 122 with second sieve material chamber intercommunication, and unqualified hot melt adhesive granule is exported from second discharging pipe 122, and the yields hot melt adhesive is then exported from first discharging pipe 121. Because sieve workbin 100 and filter screen slope set up, the material can be under the action of gravity to the discharging pipe landing, and simultaneously, the vibration subassembly orders about sieve workbin 100 vibration, makes the defective work screened out more fast at the vibration in-process, and the material can be with higher speed to first discharging pipe 121 and second discharging pipe 122 removal to effectively promote separation efficiency.

Further, the vibration assembly comprises a base 310, a plurality of vibration springs 320 arranged on the base 310, and a vibration mechanism 330 arranged on the base 310, wherein the upper ends of the vibration springs 320 are connected with the screen box 100, and the lower ends are fixed on the base 310.
