[0006] The purpose of the present invention is to provide an environment-friendly crimping device and method for regenerated polyester staple fibers, by setting cleaning components to remove impurities and dust on the surface of polyester fibers, ensuring the cleanliness of polyester fibers, and helping to improve product quality. The stretching assembly is set to apply an upward pulling force to the cleaning assembly, so that the polyester fiber is in a tensioned state, which is helpful for the conveying of the polyester fiber and the subsequent crimping operation, and the steam heating of the polyester fiber is carried out by setting a steam preheating box , which significantly improves the effect of the subsequent crimping operation. By sending out the steam in the steam preheating box and making the crimping roller fully absorb the heat in the steam to increase its own temperature, it helps to improve the crimping effect on polyester fibers and reduce The waste of energy is relatively energy-saving and environmentally friendly. By setting up an exhaust fan, the continuous output of steam and the cleaning operation of the cleaning components can be realized at the same time, which reduces equipment costs and improves the overall use effect of the crimping device. The curling operation of the fiber is carried out by pushing and squeezing the curling knife, the fiber cannot be heated, the curling effect of the fiber is not good, the product quality needs to be improved, and the fiber cannot be cleaned, and the impurities and dust on the fiber surface will also affect the product. issues that adversely affect the quality of

Embodiment 1

[0055] like Figure 1-8 As shown, the environmentally friendly crimping device for recycled polyester staple fiber proposed by the present invention includes a crimping roller assembly 1, a crimping knife 2, a vertical plate 10, a base 11 and a roller 12, and a plurality of sets of rollers 12 are installed at the bottom of the base 11. There are two sets of vertical plates 10 installed on the top of 11, the curling roller assembly 1 is arranged between the two sets of vertical plates 10, the curling knife 2 is arranged between the two sets of vertical plates 10, and the curling knife 2 includes upper and lower two groups, two. The steam preheating box 3 is fixedly installed between the vertical plates 10 by bolts, and the crimping roller assembly 1 is located between the steam preheating box 3 and the crimping knife 2. The crimping roller assembly 1 and the crimping knife 2 cooperate to make the polyester fiber Crimping (this is the prior art and will not be repeated here), a ...

Embodiment 2

[0061] like Figure 7 and Figure 10 As shown, the difference between this embodiment and Embodiment 1 is that a stretching assembly 5 acting on the cleaning assembly 4 is provided between the two sets of vertical plates 10, and the stretching assembly 5 exerts an upward pulling force on the cleaning assembly 4 to make the polyester The fibers are in tension, and the stretching assembly 5 includes a horizontal plate 501, a limit cylinder 502, a vertical rod 503, a limit slider 504 and a first spring 505. The horizontal plate 501 is fixedly connected to the two sets of vertical plates 10 through bolts. Limiting cylinders 502 are vertically arranged on both sides of the bottom of the horizontal plate 501. There are two sets of vertical rods 503 and are installed on the two sets of third connection boxes 403. The position slider 504 is connected, the outer peripheral surface of the vertical rod 503 is covered with a first spring 505, the first spring 505 is a compression spring,...

Embodiment 3

[0063] like Figure 11 As shown, the difference between this embodiment and Embodiment 1 and Embodiment 2 is that the vertical plate 10 is installed with the extrusion assembly 8 acting on the lower curling roller assembly 1, and the number of extrusion assemblies 8 is two groups and located below the two ends of the curling roller 101, and each group of extrusion components 8 includes a connecting plate 801, an oblique rod 802, a guide slider 803, a first guide groove 804, an extrusion rod 805, a cross rod 806, an extrusion block 807 and a first Two springs 808, the number of connecting plates 801 is two groups and is fixedly connected to the vertical plate 10 by bolts, the bottoms of both ends of the curling roller assembly 1 (that is, the bottom of the first connecting box 102 located below and the second connecting box 103 located below. The bottom of the two groups) are symmetrically arranged with inclined rods 802, the inclined rods 802 are inclined downward toward the d...

Abstract

The invention belongs to the technical field of polyester fiber processing, and is used to solve the problem that the existing crimping device only performs the crimping operation of the fiber through the pushing and extrusion of the crimping wheel and the crimping knife, the fiber cannot be heated effectively, and the crimping effect of the fiber is not good, The quality of the product needs to be improved, and the fiber cannot be cleaned, which will also have an adverse impact on the quality of the product, specifically an environmentally friendly crimping device for recycled polyester staple fibers and a method thereof, including a crimping roll assembly, and the setting of the crimping roll assembly between the two sets of vertical plates, the crimping knife is arranged between the two sets of vertical plates; the present invention is to provide cleaning components to remove impurities and dust on the surface of the polyester fiber, ensure the cleaning of the polyester fiber, and help improve product quality , By setting a steam preheating box to heat the polyester fiber with steam, the effect of the subsequent crimping operation is significantly improved, and the overall use effect of the crimping device is further improved.

Description

technical field [0001] The invention relates to the technical field of polyester fiber processing, in particular to an environment-friendly crimping device for regenerated polyester staple fibers and a method thereof. Background technique [0002] Polyester fiber, commonly known as polyester, is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dihydric alcohol, referred to as PET fiber. The biggest advantage of ester fiber is that it has good wrinkle resistance and shape retention, high strength and elastic recovery ability, and it is firm and durable, wrinkle-resistant and iron-free. In the production process of polyester fiber, polyester fiber generally needs to be treated Crimping operation, the crimping operation of polyester fiber is completed by a crimping device; [0003] In the Chinese patent with the application number of 202020996977.4, a crimping machine for composite fiber fabric production is disclosed, w...
