Description

Technical Field

[0001] The invention relates to the technical field of plastic particle pretreatment, in particular to an automatic sorting device for plastic particle processing. Background Art

[0002] Plastic particles are usually used in the production and processing of various plastic products. Since the particle size of plastic particles required for the production of different plastic products is different, in order to facilitate the use of manufacturers, screening machines are usually used to grade and screen the plastic particles according to the particle size requirements. At present, the most commonly used screening is to place the screen plate on a vibrating machine and use vibration to screen and sort the plastic particles on the screen plate. When the plastic particles are screened by vibration, the filtered plastic particles fall only by gravity. At the same time, since the plastic particles only fall by gravity, the plastic particles will be stuck in the screen of the screen plate, causing the screen plate to be blocked, thereby affecting the rapid screening and sorting of the plastic particles.

[0008] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0009] 1. By pouring the plastic particles from the feed funnel into the interior of the sorting cylinder, the plastic particles accumulate above the upper screen plate, and the fan is turned on to generate negative pressure suction inside the sorting cylinder. The suction generated by the fan adsorbs the screened plastic particles downward, and the fan provides downward suction for the plastic particles. At the same time, the suction generated by the fan will drive the convex plate in the synchronous kinetic energy component to contact the lower surface of the upper screen plate, driving the upper screen plate to reciprocate up and down in the sorting cylinder, so that the upper screen plate vibrates while the fan provides suction to the plastic particles, so that the plastic particles are in a vibrated state. At the same time, the adsorption force provided by the fan to the plastic particles is increased, and the plastic particles are prevented from being blocked in the upper screen plate, so that the plastic particles can be quickly screened and sorted.

[0010] 2. By setting the sleeve plate and two air duct slots, when the plastic particles are screened and fall downward from the outside of the upper screen plate, the sleeve plate assists the plastic particles to fall stably into the outside of the lower screen plate. At the same time, when the fan starts to generate suction to the inside of the sorting cylinder, the air duct slots on both sides assist and guide the negative pressure suction generated by the fan to directly contact the rotating blades, so that the suction generated by the fan drives the rotating blades to make the convex plate stably rotate on the outside of the upper screen plate, thereby improving the stable reciprocating squeezing and pushing workmanship of the upper screen plate.

[0011] 3. After screening the plastic particles on the outside of the upper screen plate, start the motor to drive the vertical axis to rotate and make the push plate rotate synchronously. The push plate rotates outside the guide table with the vertical axis as the axis toward the inside of the separation groove. The push plate rotates and causes the shielding component to shrink inside the separation groove. The push plate pushes the plastic particles on the surface of the upper screen plate and pushes them into the inside of the storage partition for collection, thereby achieving the effect of quickly discharging and collecting the plastic particles.

[0012] 4. By setting up a split component, the inside of the sorting cylinder is opened by the split component. At this time, the lower screen plate inside the sorting cylinder can be taken out, and the plastic particles placed outside the lower screen plate after sorting can be collected, so as to achieve the rapid sorting and collection of plastic particles.

[0013] 5. By setting up a shielding component, the shielding component performs a circular block on the upper part of the upper screen plate to prevent the plastic particles from escaping from the center above the upper screen plate when subjected to up and down vibrations, thereby ensuring stable sorting workmanship of the plastic particles.

[0028] Working principle:

[0029] When in use: the first step is to pour the plastic particles from the feed hopper 11 into the interior of the sorting drum 10, and the plastic particles are accumulated above the upper screen plate 15, and the fan 18 is turned on to generate negative pressure suction inside the sorting drum 10, and the suction generated by the fan 18 adsorbs the screened plastic particles downward, and the fan 18 provides downward suction for the plastic particles. At the same time, the suction generated by the fan 18 drives the rotating blades 33 to rotate outside the transmission shaft 35, and the rotation of the rotating blades 33 drives the transmission shaft 35 and causes the cam 34 to rotate, and the cam 34 continues to rotate and contacts with the lower surface of the upper screen plate 15, driving the upper screen plate 15 to reciprocate up and down inside the sorting drum 10, so that the upper screen plate 15 vibrates while the fan 18 provides suction to the plastic particles, so that the plastic particles are in a vibrated state and cooperate with the adsorption force provided by the fan 18 to the plastic particles.

[0030] By providing the sleeve plate 30 and the two air duct slots 31, when the plastic particles are screened and fall downward from the outside of the upper sieve plate 15, the sleeve plate 30 assists the plastic particles to stably fall into the outside of the lower sieve plate 16. At the same time, when the fan 18 starts to generate suction to the inside of the sorting drum 10, the air duct slots 31 on both sides assist and guide the negative pressure suction generated by the fan 18 to directly contact the rotating blades 33, so that the suction generated by the fan 18 drives the rotating blades 33 to make the convex plate 34 stably rotate on the outside of the upper sieve plate 15.

[0031] In the second step, after screening the plastic particles on the outside of the upper screen plate 15, the motor 23 is started to drive the vertical shaft 22 to rotate and the push plate 20 to rotate synchronously. The push plate 20 rotates outside the guide plate 21 with the vertical shaft 22 as the axis toward the inside of the partition groove 13. The push plate 20 rotates and contacts the inclined ring edge on the outside of the outer sealing ring plate 42 and squeezes and contracts the outer sealing ring plate 42 inside the inner ring groove 47. When the outer sealing ring plate 42 contracts, it drives the inner sealing ring plate 46 to contract inside the upper ring groove 40. At the same time, the push plate 20 squeezes the plastic particles on the surface of the upper screen plate 15 and pushes them into the inside of the storage partition 12 for collection.

[0032] The third step is to lift the insertion roller 58 upward outside the sleeve 55 and separate it from the inside of the slot 56. At this time, hold the sealing slot 51 to drive the sealing door 50 to rotate outward inside the sleeve 55 with the rotating abutment plate 54 as the center. The sealing door 50 rotates to open the inside of the sealing slot 51. At this time, the lower screen plate 16 located inside the sorting cylinder 10 can be taken out, and the plastic particles placed outside the lower screen plate 16 after sorting can be collected.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
