Description

False twister structure with front axle

The present invention relates to the construction of a false twisting machine, and more particularly to a false twisting machine construction having a front axle.

Since the surface of the raw fiber of the chemical fiber is smooth and seamless, the fabric made of the original yarn is easy to adhere to the skin due to non-absorption of water, and the touch is not good. Therefore, most of the fabric can only be used as a general fabric for making umbrellas, raincoats, General items such as canvas. If you want to make clothes or other close-fitting accessories, you need to use the false twisting machine to process the raw silk to form the loose crepe of the material, and then use the false crepe to make the fabric.

The conventional false twister structure 10, as shown in FIG. 1, includes a first active roller 12, a first driven roller 13, a heater 14, a false twister 16, a second active roller 18, and a The second driven roller 19 is provided. The raw yarn 101 passes between the first driving roller 12 and the first driven roller 13, is heated by the heater 14, and then enters the false twister 16 to perform false twisting, and finally passes through the second active roller 18 and the second driven roller 19 Between, the output becomes a false twisted yarn 103.

The rotation speed of the first driving roller 12 is slower than the rotation speed of the second driving roller 18 . By using the difference in rotational speed between the first driving roller 12 and the second driving roller 18, the original yarn 101 can be stretched. After the raw yarn 101 passes through the heater 14, it enters the false twister 16, and can be twisted by a process such as stretching, twisting or rubbing, and after being shaped by heating, it can be formed into a soft and soft false twisted yarn 103. The false crepe 103 can be further processed into a variety of fabrics, or other finished products.

Although the false twisting machine 10 of this type can produce the false twisted yarn 103 with good texture, since the material is too uniform, the fiber crystallinity of the false twisted yarn 103 is consistent with the forward direction, and the color is single and unchanged after being colored, and the texture is too Monotonous, chilly.

2 to 4 are respectively a schematic structural view of a first embodiment of the present invention, a partial structural schematic view of a front axle module, and a schematic view of an embodiment of a pre-treatment wire. As shown in the figure, the false twisting machine 20 having the front axle of the present invention comprises a front axle module 30, a wire feeding roller 22, a pressing unit 23, a heater 24, a false twister 26, and a Yarn roller 28 and a yarn pressing unit 29.

The front axle module 30 includes a front roller 36, a front spinning unit 38, and a The driving unit 34 and a toggle unit 32 are connected to the front roller 36 for driving the front roller 36 to rotate. The wire 201 passes between the front roller 36 and the front wire pressing unit 38 via the dial unit 32, passes between the wire feeding roller 22 and the spinning wire unit 23, enters the heater 24 for heating, and is further heated by the false twister 26. In the false twisting operation, the special yarn 205 is formed and finally outputted via the yarn discharge roller 28 and the yarn pressing unit 29. Wherein, the rotation speed of the front roller 36 is slower than the rotation speed of the yarn feeding roller 22, and when the thread 201 enters the region between the front roller 36 and the yarn feeding roller 22, the preliminary stretching effect is obtained due to the difference in rotation speed between the two. A pre-treatment wire 203 is formed.

The surface of the front roller 36 of the present invention has at least one imprint block 361, each imprint The block 361 has a height difference from the surface of the front roller 36, respectively. The toggle unit 32 can randomly move the wire 201 to position the contact position between the wire 201 and the front roller 36 to prevent the front roller 36 from being excessively worn due to friction with the wire 201 for a long time at a certain position. The embodiment shown in FIG. 3 is described by taking a stamp block 361 as an example, and the scope of the present invention is not limited thereto.

Since the imprint block 361 and the surface of the front roller 36 have a height difference, the thread The clamping force received by the stamping block 361 is different from that of the other portions of the front roller 36, so that the degree of stretching formed between the yarn feeding roller 22 and the yarn feeding roller 22 is also different. Therefore, the portion of the pre-treatment wire 203 passing through the surface of the front roller 36 will have a different thickness from the portion passing through the imprint block 361.

In an embodiment of the invention, each of the imprint blocks 361 can be selected as a concave A trap or a bump. If the imprint block 361 is a recessed block, when the wire 201 passes through the imprint block 361, since the pre-crushing unit 38 and the pre-roller 36 cannot form the state in which the wire 201 is held, the pre-processed wire 203 is not Stretching to form a bulky portion 207, as shown in Fig. 4.

In an embodiment of the invention, each stamp block 361 is in the axial direction of the front roller The directions respectively have a first end 363 and a second end 365, and the widths of the first end 363 and the second end 365 are not equal. In the present embodiment, when the wires 201 pass through different positions of the imprint block 361, the bulk portions 207 of different sizes can be formed.

Since the degree of stretching of the bulky portion 207 is small, if the thread of the raw yarn 201 has a color At this time, the color of the bulky portion 207 is diluted to a lesser extent, so that the false twister 26 can still have a darker color than the other portions of the thread after the false twist, thereby forming a deepening effect. If the original yarn is transparent or white, the crystallinity and the degree of forwardness of the bulky portion 207 are small, and after dyeing, more pigment can be adsorbed than other portions of the thread, and the effect of the deepening can be formed as well.

Please refer to Figure 5 and Figure 6 for the other part of the front axle module of the present invention. A schematic diagram of a partial configuration of the embodiment and a schematic view of another embodiment of the pretreatment filament. The pre-roller 56 of the present embodiment is described by taking two stamp blocks 361 and 563 as an example, but the scope of the present invention is not limited thereto.

As shown, the front roller 56 has two stamp blocks in this embodiment. 361, 563, wherein the imprint block 361 is a recessed block, and the imprint block 563 is a bump. When the wire 201 passes through the imprint block 361, the pre-treated wire 203 will produce a loft portion 207. When the wire 201 passes through the imprint block 563, since the clamping force formed between the imprint block 563 and the pre-crushing unit 38 is large, the stretching effect formed between the wire and the yarn feeding roller 22 is also large. Therefore, a tightening portion 209 will be formed on the pretreatment wire 203.

Since the stretched portion 209 has a large stretched portion, the crystallinity and the forward direction are high, because This has a lighter color than the other portions on the special yarn 205 after false twisting by the false twister 26, and the effect of floating white is formed.

In an embodiment of the present invention, since the imprint blocks 361 and 563 have different widths, the bulk portions 207 and the constricted portions 209 of different widths can be formed on the pre-treatment wires 203. Therefore, the effect of different depths of floating and floating can be formed on the special yarn 205 after the false twist.

In an embodiment of the present invention, the imprint blocks 361 and 563 may also have an irregular shape, and the bulk portions 207 and the constricted portions 209 of different sizes may be formed on the pre-treatment wires 203.

In an embodiment of the present invention, the driving unit 34 of the front axle module 30 can also change the rotational speed of the front rollers 36, 56, and can be used for the front rollers 36, 56 and the yarn feeding roller 22 by using different rotational speeds. Different tensile strengths are formed therebetween, and the action of the imprint blocks 361 and 563 can be combined to form a more diverse stretched shape on the wire 201, and a more diverse effect can be formed on the special yarn 205 after the false twist.

The above is only the embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the equivalent changes and modifications of the shapes, structures, features, methods and spirits described in the claims of the present invention. All should be included in the scope of the patent application of the present invention.
