Description

Technical Field

[0001] This utility model relates to the field of polyester filament processing technology, and in particular to a twisting device for ultra-fine denier polyester filament. Background Technology

[0002] Polyester filament is made from polyester fibers. Polyester is an important type of synthetic fiber. It is a fiber-forming polymer—polyethylene terephthalate—obtained from purified terephthalic acid or dimethyl terephthalate and ethylene glycol through esterification or transesterification and polycondensation reactions. The fiber is then spun and post-processed. In the production and processing of ultrafine denier polyester filament, twisting equipment is a crucial component.

[0003] Chinese patent CN222182624U discloses a polyester twisting device. In use, multiple strands of yarn converge in the holes of the first threading ring, and then the multiple strands of yarn are wound onto the take-up drum. The first motor and the second motor operate synchronously. The operation of the first motor drives the lower support shaft, the turntable, and the yarn on the multiple yarn drums to rotate, continuously twisting to form polyester yarn. The operation of the second motor drives the side support shaft and the take-up drum to rotate and collect the polyester yarn. After the polyester yarn is completely collected, the take-up drum can be removed from the side support shaft.

[0004] The existing technology has some shortcomings. On the one hand, it lacks a thread guiding function, which fails to guide the thread in an orderly manner during the winding process, resulting in messy and disorganized threads after winding. This not only affects the product's appearance but may also lead to problems such as thread tangling and knotting during subsequent use. On the other hand, the existing equipment lacks an effective guiding function, and the single strand of thread lacks the necessary resistance during winding, resulting in a loose structure of the twisted thread.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Please see Figure 1-3 This utility model provides a twisting device for ultra-fine denier polyester filament, comprising:

[0030] The base plate 1 has four support columns 11 fixedly connected to the four corners of the upper side wall of the base plate 1;

[0031] Top plate 2 is fixedly installed at the upper end of support column 11;

[0032] The first motor 3 is installed at the center of the upper side wall of the top plate 2. The output shaft of the first motor 3 passes through the top plate 2 and is fixedly connected to the turntable 31. The lower side wall of the turntable 31 is provided with several mounting grooves, and the wire spool 32 is detachably connected in the mounting groove.

[0033] L-shaped support 4 is fixedly installed on the upper side wall of the base plate 1. A second motor 41 is installed on one outer side wall of the L-shaped support 4. The output shaft of the second motor 41 passes through one side wall of the L-shaped support 4 and is fixedly connected to a support shaft 42. A take-up drum 43 is sleeved on the outside of the support shaft 42. The take-up drum 43 is keyed to the support shaft 42.

[0034] The yarn guiding component 5 is set on the L-shaped support 4 and is used to make the twisted yarn neatly wound on the take-up drum 43.

[0035] The wire assembly 6 is mounted on the turntable 31. The wire assembly 6 is used to draw out the single strand of wire from the wire spool 32 and to provide a certain resistance during winding.

[0036] The cable management assembly 5 includes two first support plates 51 fixed on L-shaped supports 4. A reciprocating screw 52 is rotatably provided between the two first support plates 51. Two parallel guide rods 53 are also fixedly connected between the two first support plates 51. A movable seat 54 that cooperates with the reciprocating screw 52 is slidably sleeved on the two guide rods 53. An L-shaped support plate 55 is fixedly connected to the upper side wall of the movable seat 54. A follower ring 56 is fixedly connected to the other end of the L-shaped support plate 55.

[0037] With the above structure, during the winding process, the moving seat 54 can drive the follower ring 56 to move back and forth along the winding drum 43, thereby guiding the twisted yarn in an orderly manner and ensuring that the yarn can be neatly and tightly wound on the winding drum 43.

[0038] It should be noted that the reciprocating screw 52 has two threaded grooves with the same pitch and opposite directions on its surface. A slider that matches the threaded groove is provided below the moving seat 54. By rotating the reciprocating screw 52 in one direction, the side of the helical groove pushes the slider placed in the helical groove to make axial reciprocating motion.

[0039] The conductor assembly 6 includes multiple sets of second support plates 61 arranged around the lower side wall of the turntable 31. Each set of second support plates 61 consists of two plates, and a conductor roller 62 is installed between the two second support plates 61. The conductor roller 62 has a spiral lead groove 63.

[0040] By setting up the above structure, the single strand of yarn can be wound into the spiral lead groove 63 on the lead roller 62 when it is drawn out, which provides the necessary resistance for the yarn during the winding process, making the twisted yarn structure more compact and improving the product quality.

[0041] One end of the reciprocating lead screw 52 extends to the outside of the first support plate 51 and is fixedly connected to the driven gear 521, and one end of the support shaft 42 is fixedly fitted with a driving gear 421 that meshes with the driven gear 521.

[0042] With the above structure, when the output shaft of the second motor 41 drives the support shaft 42 to rotate, it can simultaneously drive the drive gear 421 to rotate. When the drive gear 421 rotates, it can drive the driven gear 521 to rotate the reciprocating screw 52. The operation of the winding and cable management assembly 5 can be completed through a single drive source, reducing costs.

[0043] Among them, the guide roller 62 is an electric heating roller. The guide roller 62 can heat the single strand of filament when it passes through the guide groove 63, reduce the hardness of the fiber, make the fiber soft, improve the plasticity of the filament, and make the twisted filament of higher quality.

[0044] Among them, a U-shaped twisting seat 7 is fixedly connected to the lower side wall of the top plate 2, and a threading ring 71 is provided at the center of the lower side wall of the U-shaped twisting seat 7.

[0045] It should be noted that this utility model is a twisting device for ultra-fine denier polyester filament. In use, a specified number of yarn spools 32 are first installed in the mounting groove. Then, the single strand of yarn on the yarn spools 32 is pulled out and wound into the lead-in groove 63 on the guide roller 62. Next, it is led out from the lead-in groove 63 and wound onto the take-up drum 43 after passing through the threading ring 71 and the follower ring 56. Then, the first motor 3 and the second motor 41 are started. The output shaft of the first motor 3 drives the turntable 31 to rotate, causing the yarn spools 32 to rotate and twisting the multiple strands of yarn. The output shaft of the second motor 41 can drive the support shaft 42 and the take-up drum 43 to rotate. When rotating, the twisted yarn can be wound up. During the winding process, the single strand of yarn will generate a certain resistance when passing through the guide groove 63, which makes the twisted yarn tighter. When the support shaft 42 rotates, it can drive the drive gear 421 to rotate, which can drive the driven gear 521 to drive the reciprocating screw 52 to rotate. When the reciprocating screw 52 rotates, the moving seat 54 can move back and forth continuously under the guidance of the guide rod 53, which will cause the follower ring 56 to drive the twisted yarn to move back and forth continuously, so that the twisted yarn can be wound orderly on the winding drum 43. After winding is completed, the winding drum 43 can be removed.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
