Description

Technical Field

[0001] The invention relates to the technical field of plastic molding, in particular to a melt extrusion method and an extruder for regenerated environment-friendly liquid-dyed antibacterial polyester fibers. Background Art

[0002] Recycled polyester fiber is a waste product. Its raw materials primarily come from discarded spinning, polyester bottle flakes, and pulp blocks. These wastes undergo a series of recycling processes, including crushing, washing, drying, and spinning, before being processed into new fibers. Recycled polyester fibers can be categorized as long or short fibers based on their length, each with distinct application characteristics.

[0003] This fiber is significantly environmentally friendly because it significantly reduces the amount of waste and reduces pollution to the environment. Compared with traditional polyester fibers, the production process of recycled polyester fibers is more in line with the concept of sustainable development. In addition, recycled polyester fibers also have good physical properties, such as good wear resistance, high softness and comfort, and are easy to dye, which makes them widely used in clothing, household goods, industrial products and other fields. In the recycled polyester fiber, the masterbatch is mixed into the material and extruded to achieve liquid coloring, so that the fiber has strong color fastness. However, the existing polyester fiber has insufficient antibacterial ability. In order to improve the antibacterial properties of the fiber, antibacterial materials are often added during fiber extrusion. However, since antibacterial powder materials such as silver powder or ceramic powder containing silver, copper, and zinc ions are expensive, how to achieve the enrichment of antibacterial materials on the surface of the fiber and save materials as much as possible has become a problem.

[0043] The first collecting plate 51 is installed at the end of the extrusion system 2. The first collecting plate 51 is provided with a plurality of guide columns 512. The antibacterial powder flow plate 52 and the second collecting plate 53 both slide along the guide columns 512. The sides of the antibacterial powder flow plate 52 and the second collecting plate 53 are sealed by a flexible sleeve 54. The flexible sleeve 54 is provided with an air inlet pipe 55 and an air exhaust pipe 56. A powder cavity 57 is formed between the antibacterial powder flow plate 52 and the first collecting plate 51. A powder inlet pipe 522 is provided on the side of the antibacterial powder flow plate 52 close to the air inlet pipe 55. The powder inlet pipe 522 passes through the flexible sleeve 54. A powder outlet channel 523 is provided on the side of the antibacterial powder flow plate 52 close to the air exhaust pipe 56. The powder inlet pipe 522 feeds the antibacterial powder in.

The exhaust pipe 56 draws air, and the antibacterial powder is sucked in under negative pressure, and the antibacterial powder is blown away and sent into the powder chamber 57, and the antibacterial powder is sprayed onto the molten material just extruded from the extrusion hole. In order to reduce the stroke of the molten material passing through the first through hole 511, the second through hole 521 and the third through hole 531 in sequence, and facilitate the extrusion of the molten material, when the molten material is just extruded, the first collecting plate 51, the antibacterial powder flow plate 52 and the second collecting plate 53 are close to each other, which is convenient for the extrusion of the molten material.

The product has strong antibacterial ability and low cost.

[0044] Specifically, the power system 1 includes a power motor 11 and a reduction gearbox 12. The power motor 11 and the reduction gearbox 12 are both installed on the frame 6. The power motor 11 is connected to the reduction gearbox 12, and the reduction gearbox 12 is connected to the extrusion system 2. The power motor 11 drives the reduction gearbox 12 to rotate, and then the reduction gearbox 12 drives the extrusion system 2 to extrude.

[0045] Specifically, the extrusion system 2 includes an extrusion barrel 21, an extrusion screw, and a spinneret 22. The spinneret 22 is mounted at the end of the extrusion barrel 21, with extrusion holes provided on the spinneret 22. The extrusion screw is rotatably mounted within the extrusion barrel 21 and is in transmission connection with the power system 1. The rotation of the extrusion screw causes the material to be extruded from the extrusion barrel 21. A first collector plate 51 is mounted on the spinneret 22. A powder passage cavity 57 formed between the first collector plate 51 and the antibacterial powder flow plate 52 allows the molten material ejected from the spinneret 22 to pass through the first collector plate 51 in a timely manner and adhere to the antibacterial powder, ensuring that the extruded material and the antibacterial material are firmly adhered.

[0046] Specifically, the feeding system 3 includes a hopper mounted on the extrusion barrel 21 to achieve timely supply of materials.

[0047] Specifically, the heating system 4 includes several heaters, which include a heating ring 41 and a heat dissipation fan 42.

When the antibacterial powder that is not firmly adhered passes through the third through hole 531, the air flow velocity increases due to the suction of the suction pipe 56, and the antibacterial powder is extracted from the suction pipe 56 for reuse.

[0049] Specifically, the antibacterial powder flow plate 52 includes a sealed side wall 527 and a flow plate body 525. The sealed side wall 527 is installed on the flow plate body 525.

The powder outlet slits realize uniform diversion of the antibacterial powder, prevent accumulation, and ensure that the antibacterial powder adheres to each fiber evenly.

[0050] Specifically, the height of the powder inlet pipe 522 is higher than that of the powder outlet channel 523 , and the antibacterial powder is quickly diverted by the antibacterial powder diverter plate 526 under the action of its own gravity and falls and scatters.

[0051] Specifically, a control cylinder 58 is installed on the second current collecting plate 53 , one end of the control cylinder 58 is installed at the end of the extrusion system 2 , and the other end of the control cylinder 58 is installed on the second current collecting plate 53 , thereby pushing the second current collecting plate 53 .

[0052] A method for melt-extruding a regenerated, environmentally friendly, liquid-dyed antibacterial polyester fiber using a regenerated, environmentally friendly, liquid-dyed antibacterial polyester fiber melt extruder comprises the following steps:

[0053] S1: The first collecting plate 51, the antibacterial powder flow plate 52, and the second collecting plate 53 approach each other, and the power system 1 drives the extrusion system 2 to extrude the material from the extrusion hole until the material passes through the first through hole 511, the second through hole 521, and the third through hole 531 in sequence;

[0054] S2: The air is extracted from the exhaust pipe 56, and the antibacterial powder is sprayed in from the powder inlet pipe 522;

[0055] S3: The second collecting plate 53 is separated from the antibacterial powder flow plate 52 until there is no more antibacterial powder firmly attached to the molten material. The excess antibacterial powder falls off between the antibacterial powder flow plate 52 and the second collecting plate 53 and is extracted from the exhaust pipe 56.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
