Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic melt filtering, and particularly relates to a plastic melt filtering device capable of preventing blockage. BACKGROUND

[0002] In the field of plastic product processing, melt filtering is a key process for ensuring product quality. In traditional filtering devices, the filter screen is fixed between the hot melt machine and the injection mold, and the plastic melt enters the molding process after the impurities are intercepted by the filter screen. However, as the filtering continues, the accumulation of impurities can cause the filter screen to be blocked, and the filter screen must be disassembled and cleaned. This process not only consumes time and increases the intensity of manual operation, but also significantly reduces efficiency due to frequent interruptions in the production process.

[0003] To improve the above problems, the existing technology proposes a filtering device with self-cleaning function. For example, Patent No. CN211518450U discloses a device comprising a screen cylinder, a scraping plate, and a translation mechanism, which removes impurities by reciprocating the scraping plate along the inner wall of the screen cylinder and discharges them through the slag discharge pipe, which can theoretically achieve uninterrupted filtering. However, this solution still has the following defects:

[0004] 1. When the screen cylinder needs to be replaced or cleaned deeply, the linkage components such as the translation cylinder, the scraping plate, and the rear plate must be disassembled first to remove the screen cylinder. The multi-component coupled structure makes the maintenance process complicated, which increases the labor burden;

[0005] 2. Long-term disassembly causes the plastic melt remaining on the surface of the screen cylinder to condense, making it difficult for workers to clean up, resulting in longer cleaning time and affecting overall production efficiency. SUMMARY

[0043] The working principle and use process of the utility model are as follows:

[0044] In use:

[0045] When installing the hollow filter disc 552, first, place the middle part of the hollow filter disc 552 on the surface of the T-shaped column 556, and then align the counterbore 553 with the hole of the stud 551. At this time, the staff can fix and connect the hollow filter disc 552 and the stud 551 through the bolt 554. After fixing, install the sealing component 54. When installing, first, pull the pull rod 523. When the pull rod 523 moves, it will stretch the reset damping rod 522. At the same time, the pull rod 523 drives the locking rod 524 to separate from the butt joint hole 521. After separation, the staff aligns the butt joint rod 542 with the butt joint hole 521 and inserts it. At this time, the sealing circular table 544 will enter the filter box 51, and one side of the sealing cover 541 will be in close contact with one side of the filter box 51.

After resetting, the locking rod 524 is inserted into the locking hole 543, and the sealing component 54 is fixed on one side of the filter box 51.

[0046] In use, first, connect the conveying end of the hot melting machine with the feeding pipe 2, and connect the mold with the collecting pipe 9. Finally, connect the recycling equipment with the discharge pipe 4.

[0047] After connection, the hot-melt plastic melt is injected into the cylinder 1. At this time, the plastic melt will move to both sides, so that the plastic melt passes through the hollow filter disc 552, and finally flows into the collecting box 8 through the liquid discharge pipe 53 and is injected into the mold through the collecting pipe 9, which is convenient for post-injection molding.

[0048] When the plastic fluid flows into the cylinder 1, start the driving motor 7. The driving motor 7 drives the driving shaft 555 to rotate through the worm gear and the worm wheel. When the driving shaft 555 works, it drives the T-shaped column 556 and the spline rod 557 to rotate, so as to drive the cleaning shaft 32 and the cleaning knife 33 to rotate. When the cleaning knife 33 rotates, it starts to clean the impurities on the surface of the hollow filter disc 552. The cleaned impurities are located at the lower part of the inner cavity of the cylinder 1, and finally are discharged through the discharge pipe 4.
