Description

Technical Field

[0001] The utility model relates to the technical field of fiber production equipment, in particular to a raw material cleaning device for producing PTT or PBT modified fibers. Background Art

[0002] PTT / PBT modified fibers are made by melt spinning recycled polyester bottle flakes and other ingredients. Recycled polyester bottle chips are often adhered with dust and other impurities, and need to be cleaned before production and use. A cleaning device is needed to clean them. Existing cleaning devices generally require manual placement of the raw materials into a stirring device, and then stirring, with the assistance of a machine to clean the above raw materials. After cleaning, the raw materials are manually screened and fished out from the cleaning device. The more raw materials to be cleaned, the greater the burden on the staff, resulting in lower work efficiency. In addition, existing cleaning devices generally use a stirring rod to stir the raw materials when stirring and cleaning them. On the one hand, the stirring effect of this type of stirring rod is average, and on the other hand, it is easy to damage the polyester bottle flake raw materials, affecting the later salvage and even melt spinning.

Two sliding cavities 14 are symmetrically provided on the circumferential side wall of the fixed block 9, corresponding to the above-mentioned limit groove 61. An embedded limit block 15 is slidably installed in each sliding cavity 14, and a spring 16 is installed between the inner end of the limit block 15 and the inner end side of the sliding cavity 14; the outer end of the above-mentioned limit block 15 can be inserted into the limit groove 61 on the corresponding side to complete the snap-fit ​​between the material holding basket 3 and the support plate 6.

[0023] Furthermore, a connecting rod 10 is coaxially fixed to the center of the inner bottom of the material-holding mesh basket 3, arranged vertically upward, and having a hollow channel running through its length. A connecting block 11 is fixedly installed at the top of the connecting rod 10, and a pull block 12 is arranged above the connecting block 11. Two pull ropes 13 are fixedly connected to the pull block 12. The other ends of the two pull ropes 13 pass downward through the connecting block 11, the hollow channel of the connecting rod 10, the bottom of the material-holding mesh basket 3, the fixed block 9 and the sliding cavity 14 provided thereon, and are respectively fixedly connected to two limit blocks 15. Optimally, a guide shaft 17 is installed inside the fixed block 9 and on the inner end side of the sliding cavity 14. The pull rope 13 can change direction after winding around the guide shaft 17. When the pull block 12 is pulled upward, it can drive the limit block 15 to move laterally into the sliding cavity 14 and retract.

[0024] The lower end of the outer end of the above-mentioned limit block 15 is provided with an oblique edge, so that when there is no other operating means, the fixing block 9 at the bottom of the material basket 3 can be smoothly inserted downward into the connecting groove on the support plate 6 to complete the limiting fixation of the material basket 3.

[0025] The interior of the fixed base 1 is equipped with a driving mechanism capable of driving the above-mentioned washing barrel to rotate. The driving mechanism includes a rotating motor 4, which is laterally fixed to the interior of the fixed base 1, and a driving bevel gear 41 is coaxially fixed on its output end. The driving bevel gear 41 is respectively meshed with an upper driven bevel gear 42 and a lower driven bevel gear 43 rotatably mounted on the interior of the fixed base 1; wherein the upper end of the upper driven bevel gear 42 is coaxially fixed with a connecting cylinder 7, the upper end of the connecting cylinder 7 is upwardly fixedly connected to the bottom center of the outer cylinder 2, supporting and driving the outer cylinder 2 to rotate; the lower driven bevel gear 43 is coaxially arranged with the upper driven bevel gear 42, and a rotating rod 8 is coaxially fixed on its upper end.

[0027] The circumferential side walls and the bottom of the material holding basket 3 are also provided with filter mesh holes that are evenly arranged around the circumference.

[0028] The specific usage process is as follows: when in use, the raw materials are placed in the material holding net basket 3, and then the material holding net basket 3 is placed and fixed on the support plate 6; the rotating motor 4 runs, driving the active bevel gear 41 to rotate, thereby driving the upper driven bevel gear 42 and the lower driven bevel gear 43 to rotate in opposite directions, and then respectively driving the connecting cylinder 7 and the rotating rod 8 to rotate, the connecting cylinder 7 drives the outer cylinder 2 to rotate, and the rotating rod 8 drives the support plate 6 to rotate. Since the rotating column 5 and the outer cylinder 2 are connected by a bearing, the outer cylinder 2 and the material holding net basket 3 on the support plate 6 can rotate relatively smoothly in opposite directions, and the cleaning liquid inside can better clean the raw materials.

[0029] After cleaning is completed, the rotating motor 4 stops running; then the pulling block 12 is pulled upward, and the two limit blocks 15 are driven by the two pull ropes 13 to shrink and slide into the corresponding sliding cavity 14, so that the outer end of the limit block 15 is disengaged from the limit groove 61; then the connecting block 11 is pulled upward, and the material holding net basket 3 is lifted up through the connecting rod 10, and the cleaned raw materials are all taken out from the outer cylinder 2 along with the material holding net basket 3, which is convenient for flow to the next process. It is easy to use and can improve the cleaning efficiency.
