Technical Field
[0001] This utility model relates to the field of extrusion press technology, and more specifically, to a magnetic iron removal device for the extrusion press feed port. Background Technology
[0002] Chinese Utility Model Patent Application No. CN202120181083.4 discloses a screw extruder for processing fermented corn, relating to the agricultural field. This utility model aims to solve the problems of current twin-screw extruders for processing fermented corn, which are inconvenient for removing attached fermented corn and have insufficient extrusion pressure. This utility model features through holes on the outer periphery of the twin screws and a movable sleeve inside the cavity of the twin screws. The through holes on the movable sleeve correspond to the through holes on the upper screw, and a blower removes the fermented corn attached to the twin screws. Simultaneously, a shearing block is added to increase the extrusion pressure of the twin-screw extruder.

[0032] As described in the background section, there is a situation where raw materials and iron filings are fed together at the feed port of the extruder, resulting in the produced products containing foreign matter such as iron filings, which makes it impossible to ensure their quality and safety.

[0038] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0039] Example 1
[0040] Please refer to Figure 1-6A magnetic iron removal device for the discharge port of an extruder includes: a mounting frame 1, on which an extruder body 2 is mounted; an iron removal frame 3 is installed at the discharge port of the extruder body 2; a collection box 4 is installed on the lower side of the iron removal frame 3; collection boxes 5 are slidably fitted on both sides of the iron removal frame 3; a snap-fit assembly is provided between the collection box 5 and the iron removal frame 3; magnetic rods 8 are rotatably fitted on both sides inside the iron removal frame 3; the magnetic rods 8 cooperate with the iron removal frame 3; a dispersion assembly and a driving assembly are respectively provided inside and outside the iron removal frame 3; the driving assembly cooperates with the two magnetic rods 8. The upper and lower sides of the iron removal frame 3 are divided into a dispersion chamber 6 and two iron removal chambers 7, which are connected. One side of the inner wall of each of the two iron removal chambers 7 is an arc-shaped surface 18; and a scraper 9 is installed inside the collection box 5. The inner walls of the dispersion chamber 6 are provided with first rotating grooves 12 on both sides, and the inner walls of the two iron removal chambers 7 are provided with second rotating grooves 13 on both sides. The bottoms of the two iron removal chambers 7 are provided with discharge ports 14. Baffle plates 17 are installed at the connection points between the dispersion chamber 6 and the two iron removal chambers 7. The dispersion assembly includes a first rotating rod 19 rotatably fitted within the first rotating groove 12. Multiple dispersion frames 20 are installed around the periphery of the first rotating rod 19. A fixing plate 21 is installed on the outer side of the iron removal frame 3. The drive assembly is mounted on a servo motor 22 on the fixing plate 21. The output shaft of the servo motor 22 is equipped with a first gear 23. A second gear 24 is installed at one end of each of the two first rotating rods 19. The two second gears 24 are located on both sides of the first gear 23 and mesh with it. The magnetic rod 8 is equipped with a second rotating rod 25 on both sides. The second rotating rod 25 is rotatably fitted in the second rotating groove 13. One end of the first rotating rod 19 and the second rotating rod 25 is equipped with a pulley 26. A transmission belt 27 is provided between the two pulleys 26.
[0041] Implementation process: By turning on the servo motor 22, the first gear 23 is driven to rotate. The rotating first gear 23 drives the second gears 24 on both sides to rotate in opposite directions. The two second gears 24 drive the first rotating rod 19 and the dispersing frame 20 to rotate, which disperses the material in the dispersing chamber 6, so that the iron filings and foreign objects mixed in the material are dispersed. The dispersed material falls downwards by gravity to the arc-shaped surfaces 18 on both sides, which slows down the speed. The baffles 17 on both sides guide the falling material. At this time, the two second gears 24 rotating in opposite directions drive the two magnetic rods 8 to rotate in opposite directions in the iron removal chambers 7 on both sides through the pulley 26 and the transmission belt 27. At this time, the rotating magnetic rods 8 attract the iron filings and foreign objects in the material. When the magnetic rods 8 that have attracted the iron filings and foreign objects rotate to the scraping plate 9, the iron filings and foreign objects on their surface are scraped off and collected in the collection box 5.
[0042] Benefits of implementation: The magnetic rod 8 and the scraper 9 work together to facilitate the real-time collection of iron filings and foreign objects in the material.
[0043] Example 2
[0044] A handle 10 is installed on one side of the collection box 5, and a positioning block 11 is installed on the bottom of the collection box 5. Placement slots 15 are provided on both sides of the iron removal frame 3. The collection box 5 is slidably fitted within the placement slots 15. A positioning groove 16 is provided at the bottom of the inner wall of the placement slot 15, and the positioning block 11 is slidably fitted within the positioning groove 16. A sliding groove 28 is provided on one side of the positioning groove 16. The locking assembly includes a locking block 29 that is slidably fitted within the sliding groove 28. An elastic element 30 is installed between the locking block 29 and one side of the inner wall of the sliding groove 28. A lever 31 is installed on one side of the locking block 29, and the lever 31 is located on the outside of the collection box 5.
[0045] Implementation process: By sliding the collection box 5 into the placement groove 15, the positioning block 11 slides into the positioning groove 16 to press the locking block 29. The inclined side of the locking block 29 is set outward to facilitate the sliding of the positioning block 11 into the positioning groove 16. The locking block 29 is reset by the force of the elastic element 30, so that the collection box 5 can be installed in the iron removal chamber 7, so that the scraping plate 9 and the surface of the magnetic rod 8 are in contact to scrape off the iron filings and foreign objects on their surface. Conversely, by pulling the lever 31, the locking block 29 is moved into the sliding groove 28, which makes it easy to take out the collection box 5.
[0046] Benefits of implementation: The snap-fit assembly makes it easy to detach and assemble the collection box 5 from the iron removal frame 3, and makes it easy to empty the iron filings and foreign objects collected in the collection box 5.
