Problems solved by technology

The seamless underwear circular machine adopts the suction and negative pressure pulling method. When weaving, the suction motor starts to work, and the damper controller driven by the stepping motor provides the pulling force to pull the clothes from the feeding port to the discharging The bell mouth, and the different lengths of clothing fabrics are not uniformly pulled, and there may be problems such as uneven clothing appearance
[0003] In addition, due to the small weight of light and thin fabrics during the weaving process, the negative pressure generated by the suction fan cannot provide sufficient pulling force for the fabric, and the fabric is easy to float out of the gap between the needle cylinder and the Huff dial, and the fabric loops are insufficient. , easy to cause fabric defects and damage knitting needles
In addition to ultra-thin fabrics, some special pleated fabrics or high-elastic fabrics experience excessive shrinkage of the fabric during weaving, and accumulate at the needle cylinder opening, resulting in knitting needle defects and broken needles; Fabrics that are too long are more likely to be pulled by suction and negative pressure than fabrics that are too short, resulting in problems such as differences in the appearance of fabric loops
[0004] However, regarding the problem of uneven pulling force on the fabric, in the prior art, elastic yarns are mostly used for weaving. After being boiled off the machine, the fabric shrinks, and the problem of uneven appearance will become less obvious, which limits the selection of yarns. , also restricts the application of the developed product, so there is still no effective solution

Embodiment 1

[0060]The present embodiment provides an inductive uniform tension seamless underwear circular machine pulling device. Take the pulling device of the Santo Tony TOP-2 seamless single-sided jacquard underwear round machine as an example, the specific parameters are: machine number E28; Number of needles 1344; Barrel diameter 15 inches. as Figure 1 As shown, the seamless underwear circular machine adopts the method of suction negative pressure traction, when weaving, the suction motor device begins to work, and the damper controller driven by the stepper motor provides pulling force, pulling the clothing from the unloading port to the outlet flare, and the pulling force of the clothing fabric of different lengths and short sections is uneven, and the appearance of the clothing will be uneven.

[0061] The present embodiment provides an inductive seamless underwear circular machine, such as Figure 1 As shown, the underwear circular machine comprises a body, a pulling device, a clothi...

Embodiment 2

[0070] The present embodiment provides a traction device of an inductive uniform tension seamless underwear circular machine. as Figure 4 Shown, the seamless underwear circular machine traction system induction device 11 is located in the 8 wall of the cloth tube and the bottom of the Huff disc 9, the induction device of the fusk 8 and the Huff disc 9 by sensing the pressure of different fabrics in its vertical direction to work. When weaving high-elastic, specially organized fabrics, fabric fabrics will have weaving problems such as excessive shrinkage and folding, or accumulation in the gaps in the bottom of the disc without pulling. The present embodiment is provided with an induction device in the syringe and the Huff disc, Figure 5 The induction device showing the bottom of the Huff disc 9, when weaving this type of fabric, the fabric is easy to shrink seriously, folds into clumps, the suction negative pressure on the fabric has a small pulling force, the fabric begins to acc...

Embodiment 3

[0072]The present embodiment provides a induction uniform tension seamless underwear circular machine traction device, suction unit negative pressure x in the normal state of 60.0kpa ~ 70.0kpa or so, and the use of two kinds of fine denier fiber or ultra-fine denier fiber as raw material, the fabric is extremely thin, suction negative pressure on the fabric of the pull is small, the pressure change in the vertical direction of the cylinder wall is not easy to capture, the induction device is extremely sensitive, so the pulling device described in the present embodiment is provided with an induction device at different diameters of the winding tube (a, b, c, d, e), This is shown in Figure 6(a) and Figure 6(b). When weaving, the induction device at a place senses the fabric, and feedback to the control system to control the suction unit 1 gear of strength (+20.0kpa), as the fabric continues to weave, the fabric is still relatively thin, but the fabric fabric becomes longer, the suct...

Abstract

The invention discloses an inductive seamless underwear circular knitting machine and a method for controlling fabric pulling force, belonging to the technical field of knitting circular weft knitting machines. The circular knitting machine for underwear includes a main body, a winding drum, a half disc and a pulling device. The circular knitting machine is provided with an induction device at the opening of the winding drum and / or the half disc, and the sensing device is used to sense the movement of the circular knitting machine. The pulling force that the fabric fabric receives during the weaving process; the pulling device includes a suction unit, which is connected to the suction port through a trachea and a stepping motor, and the suction unit is used to control the work of the suction port state. The sensing device is connected to the control system through a circuit, and the control system is connected to the suction unit. The circular knitting machine captures the pulling force of the fabric through the sensing device and feeds it back to the control system in time. The pulling force collected by the device changes the suction negative pressure in time, so that the pulling force on the fabric of the circular knitting machine is uniform during the weaving process.

Description

Technical field [0001] The present invention relates to an induction type seamless underwear circular machine and a method of controlling the pulling force of the fabric, which belongs to the technical field of knitting circular weft machine. Background [0002] In order to adapt to the improvement of people's living and working environment and the requirements of wearing comfort, as well as the application of fine yarn branches, the lightness and thinning of knitted underwear products has become a popular trend. In the seamless underwear circular machine, the pulling mechanism adopts the suction type, and the suction force generated by the suction fan is used to absorb the fabric, so that the formed fabric is drawn out of the circle area to ensure the smooth progress of weaving. Seamless underwear round machine using suction negative pressure traction method, in the weaving, suction motor began to work, by the stepper motor driven damper controller to provide pulling force, the ...
