The scraper cooperates with the side wall of the filter cylinder. An outlet component is provided inside the rotating cylinder to discharge impurities from the filter cylinder. A rotating component is provided on the connecting frame to drive the filter cylinder to rotate and accelerate the filtration of hot melt adhesive.

[0005] Furthermore, the filter cartridge comprises, from top to bottom, a straight cylinder, an inverted cone cylinder, and a collection platform, with the diameters of the straight cylinder, the inverted cone cylinder, and the collection platform decreasing sequentially.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Combined with appendix Figure 1 Appendix Figure 2 and attached Figure 3 A high-efficiency hot melt adhesive filtration device includes a support and a filter tank 1 mounted on the support. The bottom of the filter tank 1 is provided with an adhesive outlet pipe 2. The filter tank 1 is provided with a filter cylinder 3. The filter cylinder 3 includes a straight cylinder 9, an inverted cone cylinder 10 and a collection platform 11 from top to bottom. The diameters of the straight cylinder 9, the inverted cone cylinder 10 and the collection platform 11 decrease sequentially.

[0024] During the production of hot melt adhesives, various impurities and particles, such as unmelted raw materials, are often mixed in. If these are not filtered, they can easily affect product quality and clog nozzles and adhesive circuits during use.

[0025] Existing hot melt adhesive filtration devices mostly use plate-shaped or cylindrical 9-type filter screens for filtration.

[0026] In this application, the filter cylinder 3 includes a straight cylinder 9, an inverted cone cylinder 10 and a collection platform 11 from top to bottom, with the diameter decreasing sequentially. Filter holes are provided on both the straight cylinder 9 and the inverted cone cylinder 10, and filter holes can be provided on the collection platform 11 as needed, so that solid impurities in the hot melt adhesive can accumulate on the collection platform 11.

[0027] Combined with appendix Figure 3 Appendix Figure 4 and attached Figure 6 The top of the filter cartridge 3 is rotatably installed through the filter tank 1. The filter tank 1 is provided with a connecting frame 4. The connecting frame 4 is provided with a rotating component 8 that can drive the filter cartridge 3 to rotate and accelerate the filtration of hot melt adhesive. The rotating component 8 includes a second gear set 19 on a drive shaft 17. The drive shaft 17 drives the rotating drum 5 through the second gear set 19. The rotating drum 5 is provided with a third gear set 20. The rotating drum 5 drives the filter cartridge 3 through the third gear set 20.

[0028] Due to its physical properties, hot melt adhesive has high viscosity without external force, resulting in low filtration efficiency.

[0029] In this application, the filter cartridge 3 is driven to rotate by the rotating component 8, which generates centrifugal force in the filter cartridge 3. Under the action of centrifugal force, the hot melt adhesive passes through the filter holes on the filter cartridge 3 and is introduced into the bottom of the filter tank 1. Finally, it is discharged through the adhesive outlet pipe 2, which facilitates the improvement of filtration efficiency.

[0030] The drive shaft 17 drives the rotating drum 5 through the second gear set 19. The rotating drum 5 drives the third gear set 20 and the scraper 6 to rotate. The third gear set 20 is a planetary gear set, including a sun gear on the rotating drum 5. The connecting frame 4 is provided with planetary gears meshing with the sun gear on both sides of the sun gear. The top of the filter cylinder 3 is provided with a gear ring meshing with the planetary gears. The rotating drum 5 drives the sun gear to rotate. The sun gear drives the gear ring through the planetary gears to rotate the filter cylinder 3, thereby generating centrifugal force.

[0031] Combined with appendix Figure 3 Appendix Figure 4 and attached Figure 6 A rotating cylinder 5 is rotatably mounted on the connecting frame 4. The bottom end of the rotating cylinder 5 extends to the bottom of the filter cylinder 3 and is provided with a scraper 6 at the end. The scraper 6 cooperates with the side wall of the filter cylinder 3. The diameter of the rotating cylinder 5 is not greater than the diameter of the collection platform 11, and there is a gap 21 between the bottom wall of the rotating cylinder 5 and the collection platform 11. An outlet assembly 7 is provided inside the rotating cylinder 5 to export impurities from the filter cylinder 3. The outlet assembly 7 includes an outlet pipe 12 provided on the filter tank 1. The outlet pipe 12 has an L-shaped structure. The bottom end of the outlet pipe 12 is rotatably sealed to the top end of the rotating cylinder 5. A rotating shaft 13 is rotatably mounted inside the outlet pipe 12. A driving component 14 is provided on the connecting frame 4 to drive the rotating shaft 13 to rotate. The rotating shaft 13 extends to the bottom end of the filter cylinder 3 and is provided with a spiral plate 15 on the outside. The spiral plate 15 is provided with several filter holes.

[0032] Combined with appendix Figure 5 The driving component 14 includes a motor 16 mounted on the connecting frame 4. The power output end of the motor 16 is provided with a drive shaft 17. The drive shaft 17 is provided with a first gear set 18. The drive shaft 17 drives the rotating shaft 13 through the first gear set 18.

[0033] Most existing filter components are equipped with scrapers 6, which can scrape off impurities on the filter cartridge 3. However, the density of the scraped impurities is greater than that of hot melt adhesive. Under the combined action of centrifugal force and gravity, they are eventually collected on the collection platform 11, requiring subsequent manual removal.

[0034] Impurities collected by scraper 6 are guided to collection platform 11. The gap 21 facilitates the introduction of impurities into the spiral plate 15. Motor 16 drives drive shaft 17 to rotate. Drive shaft 17 drives rotating shaft 13 to rotate relatively slowly through first gear set 18. Rotating shaft 13 drives spiral plate 15 to transfer impurities on collection platform 11 to outlet pipe 12 at the top of rotating drum 5. Finally, the impurities are discharged through the other end of outlet pipe 12. Due to the filter holes on spiral plate 15, hot melt adhesive can easily flow back into filter cylinder 3, which helps to avoid exporting hot melt adhesive as much as possible while exporting impurities.
