Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a texturing machine guide structure for producing composite textured yarn (DTY). Background Technology

[0002] In the modern textile industry, the key technology is to use texturing machines to process pre-oriented yarn (POY) into textured yarn (DTY) with elasticity and bulkiness. In order to obtain a wider variety of fabric styles, it has become a mainstream trend to combine fibers with different properties (such as conventional polyester POY, T8 polyester POY, fully oriented yarn FDY, etc.) for texturing.

[0003] However, in existing TMT texturing machines and similar equipment, all the yarn bundles that need to be combined must typically be joined together before entering the shaping hot box (second hot box) and then undergo heat treatment together in the hot box. This single processing path has significant drawbacks: 1. Inability to meet the heat treatment requirements of different components: Some components (such as FDY and spandex, which already have ideal properties) do not require or are even averse to high-temperature setting. Forcing them through a hot box will lead to performance degradation, such as decreased strength of FDY, melting of low-melting-point fibers, and loss of elasticity in spandex.

[0004] 2. Limited product design space: Since all components must undergo the same heat treatment, process designers cannot fully utilize the properties of certain fibers (such as the low shrinkage of FDY) to create a more extreme differential shrinkage fluffy effect.

[0005] Therefore, there is an urgent need in the field for a texturing machine guide device that allows different filament bundles to selectively pass through or avoid the shaping heat box according to their characteristics, in order to achieve high-performance composite filament production. Utility Model Content

[0006] In view of this, the purpose of this utility model is to propose a texturing machine guide structure for producing composite textured yarn (DTY) to solve the problem that all composite yarn components must pass through the setting heat box together, which leads to damage to some fiber properties and limitations on the style of the final product.

[0007] To achieve the above objectives, this utility model provides a guide structure for a texturing machine used in the production of composite textured yarn (DTY), the guide structure being disposed on the outer wall of the setting heat box; the guide structure includes: The support frame is fixedly installed on the outer wall of the shaping and heating box; At least one guide tube is installed on the support frame, and the axis of the guide tube is parallel to the path of the yarn through the setting heat box.

[0008] Preferably, multiple guide tubes are arranged radially and perpendicular to the path of the yarn through the setting heat box.

[0009] Preferably, the length of the guide wire tube is consistent with the effective heating length of the shaping heat box.

[0010] Preferably, a gap is left between the support frame and the outer wall of the shaping hot box, and a heat insulation plate fixedly connected to the support frame is provided in the gap, wherein the heat insulation plate is made of aluminum silicate fiber board.

[0011] Preferably, the guide tube is provided with aluminum heat dissipation fins and a cooling fan on the side away from the shaping heat box. The aluminum heat dissipation fin group is directly fixed to the cooling fan through a metal frame, and the inner side of the aluminum heat dissipation fin group is in contact with the outer wall of the guide tube. The airflow output by the cooling fan passes through the gap between adjacent aluminum fins to dissipate heat from the guide tube.

[0012] Preferably, one side of the metal frame is hinged to the support frame, with the hinge axis parallel to the axis of the guide tube, and the other side of the metal frame is provided with a male buckle with a snap-fit ​​structure, and the support frame is provided with a female buckle with a corresponding snap-fit ​​structure.

[0013] Preferably, the support frame has an upper beam and a lower beam, and the two ends of the guide wire tube are fixedly connected to the upper beam and the lower beam respectively by pipe clamps. The pipe clamps are U-shaped pipe clamps that are fixed to the beam with bolts, and the inner wall of the pipe clamps is provided with rubber that contacts the outer wall of the guide wire tube.

[0014] Preferably, the outlet end of the guide tube is provided with a guide wheel for guiding the wire bundle path.

[0015] The beneficial effects of this utility model are: 1. The utility model achieves "differentiated processing" of different heat-sensitive fibers by separating paths in physical space, effectively avoiding problems such as strength reduction and elasticity failure caused by unnecessary heat treatment of fibers such as FDY and spandex, and ensuring the integrity of the functions of each component in the final product.

[0016] 2. Significantly reduced energy consumption: By allowing some of the filaments to avoid the high-temperature heating box, the electrical energy consumption required for heating is directly reduced.

[0017] 3. Improve product quality and added value: Because the low shrinkage of FDY is perfectly preserved, it creates a greater shrinkage difference with high-shrinkage POY, which improves the bulkiness of the final DTY; avoids heat damage and improves the overall strength of the composite yarn; and provides core raw materials for developing high-end fabrics with unique structures and styles.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0022] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0023] This utility model proposes a guide structure for a texturing machine used in the production of composite textured yarn (DTY), such as... Figures 1 to 4 As shown, the guide wire structure is disposed on the outer wall of the shaping heat box, and its structure includes: The support frame 1 is fixedly installed on the outer wall of the shaping heat box to provide stable support for the guide tube 2 and other components. The support frame 1 has an upper beam and a lower beam.

[0024] At least one guide tube 2 is mounted on the support frame 1, with its axis parallel to the path of the yarn passing through the setting heat box. It is used to transport heat-sensitive yarn bundles (such as FDY and spandex) that do not require setting. Multiple guide tubes 2 can be arranged radially and perpendicular to the path of the yarn passing through the setting heat box to accommodate the simultaneous processing of multiple yarn bundles. The length of the guide tube 2 is consistent with the effective heating length of the setting heat box, ensuring that the yarn bundle transport rhythm is synchronized with the yarn bundles inside the heat box. A guide wheel 7 is provided at the outlet end of the guide tube 2 to precisely guide the yarn bundle path, ensuring the subsequent yarn bundles merge and reducing or avoiding scratching against the inner wall of the guide tube 2, guiding the yarn bundles precisely to subsequent merging components (such as yarn guides and network nozzles).

[0025] The two ends of the guide wire tube 2 are fixedly connected to the upper beam and lower beam of the support frame 1 by pipe clamps 6 respectively. The pipe clamps 6 are U-shaped pipe clamps 6, which are fixed to the beam by bolts. The inner wall of the pipe clamp 6 is provided with a rubber layer that contacts the outer wall of the guide wire tube 2, which not only achieves a stable fixation, but also avoids wear of the guide wire tube 2 due to hard contact.

[0026] A gap is left between the support frame 1 and the outer wall of the shaping heat box. A heat insulation plate 3 is fixedly connected to the support frame 1 in the gap. The heat insulation plate 3 is made of aluminum silicate fiberboard (but not limited to this). Its excellent heat insulation performance can effectively block the heat radiation of the shaping heat box from being transmitted to the wire guide tube 2, creating a low temperature transport environment for the heat-sensitive wire bundle.

[0027] The guide tube 2, away from the shaping heat box, is equipped with aluminum heat dissipation fins 41 and a cooling fan 4. The aluminum heat dissipation fins 41 are directly fixed to the cooling fan 4 via a metal frame 5. The inner side of the aluminum heat dissipation fins 41 are in contact with the outer wall of the guide tube 2, which can quickly dissipate the heat of the guide tube 2. The airflow output by the cooling fan 4 passes through the gap between adjacent aluminum fins, efficiently dissipating heat from the guide tube 2 and further controlling the temperature inside the tube. One side of the metal frame 5 is hinged to the support frame 1, with the hinge axis parallel to the axis of the guide tube 2. The other side of the metal frame 5 is equipped with a male buckle 51 with a snap-fit ​​structure, and the support frame 1 is equipped with a female buckle 52 with a corresponding snap-fit ​​structure. This design allows the cooling structure to be opened and closed easily, facilitating the inspection and maintenance of the guide tube 2.

[0028] Workflow: 1. The filament bundles that need to be shaped enter the shaping hot box through the conventional path to undergo the necessary heat shaping treatment in order to eliminate internal stress and stabilize the curled structure.

[0029] 2. Non-setting yarn bundles (e.g., fully oriented FDY, spandex, etc.): These yarn bundles do not enter the setting heat box, but are instead introduced into parallel guide tubes 2. Within these tubes, the yarn bundles are transported at or near room temperature, completely avoiding heat treatment.

[0030] 3. Final Fusion: The filament bundles treated in the shaping heat box and those passing through the parallel guide tube 2 are precisely fused at the guide tube below the outlet of the shaping heat box. Subsequently, the fused filament bundles pass together through the network nozzle and are finally wound into shape.

[0031] The resulting composite DTY has a full and fluffy feel and excellent elasticity; compared with passing all the filaments through a single shaping heat box, this product has higher loft and higher breaking strength; the processing is stable and the FDY is free of stiff or fuzzy fibers.

[0032] During the above production process, the cooling fan 4 runs continuously, and the airflow passes through the gaps between the fins to remove heat. Together with the heat insulation plate 3, it maintains the low temperature environment inside the guide tube 2, ensuring that the performance of heat-sensitive yarns such as FDY and spandex is not damaged during the transportation process, and finally produces composite textured yarn DTY with high bulk and excellent elasticity.

[0033] When the guide tube 2 needs to be cleaned or repaired, simply unfasten the metal frame 5 and flip the cooling assembly around the hinge axis to easily operate the guide tube 2, greatly improving the convenience of operation and maintenance.

[0034] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0035] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
