Description

Technical Field

[0001] The utility model relates to the technical field of recycled plastic processing equipment, in particular to a fully automatic feeding device for recycled plastic particle production. Background Art

[0002] Recycled plastics refer to plastic raw materials obtained after processing waste plastics through physical or chemical methods such as pretreatment, melt granulation, and modification. It is the reuse of plastics. A feeding device is required during the pretreatment process.

[0003] After searching, the publication number CN219155859U is a negative pressure feeder for recycled plastic bottle flakes, which includes a raw material box and a feeder box. A conveying pipe is provided at the bottom of the raw material box, and the other end of the conveying pipe is connected to the feeder box. An exhaust fan is provided on the top of the feeder box. A filter screen is movably installed inside the feeder box through an anti-blocking vibration unit. The anti-blocking vibration unit includes connecting blocks fixed at both ends of the filter screen and a vibration groove opened on the feeder box, and the connecting block is slidably installed in the vibration groove. Compared with the prior art, the utility model can maintain a high-frequency vibration state of the filter screen during negative pressure feeding by arranging an anti-blocking vibration unit between the feeder box and the filter screen, so that the suction screen can be sucked. The recycled plastic flakes attached to its surface vibrate down, thereby preventing the flakes from being adsorbed and blocked in the filter and causing obstructed exhaust, which can ensure good exhaust of negative pressure feeding, thereby ensuring stable negative pressure feeding effect and efficiency. However, the negative pressure feeding machine only uses an exhaust fan to drive the filter to vibrate, and the vibration effect is poor. After the actual feeding is completed, the exhaust fan needs to be turned off. At this time, the filter will no longer be able to vibrate, resulting in smaller raw materials remaining on the surface of the filter, and the feeding effect cannot be well guaranteed. Before the negative pressure feeding works, raw materials accumulate in the raw material box, which will cause the raw materials to block the discharge pipe at the bottom of the raw material box, and then the exhaust fan cannot be used for feeding, resulting in low feeding efficiency.

[0004] To this end, a fully automatic feeding device for the production of recycled plastic particles is proposed, which has the advantages of good feeding effect and high feeding efficiency, thereby solving the problems in the above-mentioned background technology. Utility Model Content

[0033] Working principle:

[0034] When in use, in the utility model, the raw material box 1 filled with raw materials through the feed hopper 15 is moved to the side of the upper material box 2, and the two ends of the conveying pipe 13 are respectively connected with the discharge pipe 12 and the feed pipe 14. The anti-blocking stirring mechanism is formed by setting the stirring motor 6, the stirring paddle 7, the stirring rod 9, and the scraper 10. In this mechanism, the battery set in the battery box 8 provides electric energy for the stirring motor 6, so that the stirring motor 6 drives the anti-blocking stirring mechanism to rotate. When the anti-blocking stirring mechanism rotates, the raw materials in the raw material box 1 can be lifted up to ensure the air permeability in the raw material box 1, and the raw materials are prevented from accumulating at the bottom of the raw material box 1 to block the discharge pipe 12 and cause In the event that the material cannot be fed, the feeding effect can be guaranteed, the feeding effect of the device can be better, and the feeding efficiency can be improved.

When feeding, the exhaust fan 16 is turned on, which can keep the second filter 17 and the third filter 18 in a high-frequency vibration state, so as to avoid the sheet material being adsorbed and blocked in the filter and causing the exhaust to be blocked.

Through this morphological structure, it is more conducive to the falling of raw materials with smaller surface volume on the second filter screen 17 and the third filter screen 18 to avoid raw material residue. After the feeding is completed, the second filter screen 17 and the third filter screen 18 can be driven to vibrate by the vibration motor 23 alone, so that the raw materials with smaller surface volume fall off to avoid raw material residue. When the raw materials enter the interior of the feeding box 2, A raw material crushing mechanism is formed by setting a crushing motor 20 and a crushing roller 26.
