A polyester grey fabric air-jet loom

Abstract

This utility model relates to a polyester greige fabric air-jet loom. The structure includes: an air-jet loom body, a take-up roller, and a pressing mechanism. The back of the air-jet loom body is the greige fabric output end. A take-up roller for taking up the greige fabric is rotatably connected to the air-jet loom body. A pressing mechanism for tension adjustment is provided on one side of the take-up roller. By installing the pressing mechanism, the take-up roller takes up the fabric output from the air-jet loom body. As the fabric diameter increases, an electric push rod inside the protective shell is activated. The moving end of the electric push rod gradually extends, driving the displacement frame to gradually approach the take-up roller. The pressure applied by the pressing component continuously increases, compensating for the tension of the fabric and ensuring tension balance during fabric take-up.

Description

Technical Field

[0001] This utility model relates to the field of air-jet loom technology, and in particular to an air-jet loom for polyester fabric. Background Technology

[0002] The "air jet loom" is an automated weaving device that uses compressed air as the power source for weft insertion. Its core principle is to use jet airflow to pull the weft yarn through the warp yarn opening at high speed to complete the fabric interlacing. This model adopts electronic control technology, which can precisely adjust the airflow pressure, jet timing and opening angle. It is suitable for various yarns such as cotton, chemical fiber and blended yarns. The weaving speed can reach more than 1,000 revolutions per minute, which is far more efficient than traditional shuttle looms. Its advantages are low noise, low vibration, optimized energy consumption, and support for the production of high-density fabrics and complex jacquard structures.

[0003] In the processing stage of air-jet looms, circular rollers are typically used to wind up the fabric. However, these rollers have a design flaw: they lack a tension adjustment structure around them. During the winding process, as the fabric continues to wind up and its diameter increases, the lack of effective tension adjustment causes tension fluctuations. These tension fluctuations can lead to a series of problems, such as the fabric becoming tight on the inside and loose on the outside, or wrinkles forming. These problems can negatively impact subsequent processing, making it difficult to achieve the desired processing results. Ultimately, this reduces the quality of the fabric winding, affecting the entire production process and product quality.

[0004] Therefore, in response to the above problems, a new air-jet loom for polyester greige fabric is proposed. Utility Model Content

[0005] To overcome the problems existing in related technologies, this utility model provides a polyester fabric air-jet loom that can control the pressure roller to squeeze the fabric during the winding process via an electric push rod, thereby compensating for the tension attenuation caused by the increase in fabric diameter and ensuring tension balance.

[0006] To achieve the above objectives, the first aspect of this utility model provides a polyester grey fabric air-jet loom, comprising:

[0007] Air-jet loom body, take-up rollers, and extrusion mechanism;

[0008] The back of the air-jet loom is the fabric output end. A take-up roller for taking up the fabric is rotatably connected to the air-jet loom body. A pressing mechanism for tension adjustment is provided on one side of the take-up roller.

[0009] The extrusion mechanism includes a protective shell, an extrusion assembly, a displacement frame, and an electric push rod;

[0010] A protective shell is provided on one side of the take-up roller, and an extrusion assembly is provided between the take-up roller and the protective shell. The extrusion assembly is in contact with the surface of the fabric. A displacement frame is installed on the extrusion assembly. An electric push rod is fixedly connected inside the protective shell, and the output shaft of the electric push rod is fixedly connected to the displacement frame.

[0011] Furthermore, an infrared pressure detector is fixedly connected to the upper surface of the protective shell.

[0012] Furthermore, limit seats are fixedly connected to both sides of the protective shell, and T-shaped rods that slide through the limit seats are symmetrically fixedly connected to the displacement frame.

[0013] Furthermore, the extrusion assembly includes an extrusion roller and an extrusion pad;

[0014] A compression roller is fixedly connected to the displacement frame, and compression pads are equidistantly sleeved on the compression roller.

[0015] Furthermore, the extrusion assembly also includes a first adhesive sheet and a second adhesive sheet;

[0016] A first adhesive sheet is fixedly connected to the surface of the extrusion roller, and a second adhesive sheet is fixedly connected to the surface of the extrusion pad near the surface of the extrusion roller. The first adhesive sheet and the second adhesive sheet are bonded to each other.

[0017] Furthermore, a rubber pad is fixedly connected to the surface of the take-up roller.

[0018] Furthermore, the surface of the T-shaped rod is provided with a spiral groove.

[0019] The technical solution provided by this utility model can include the following beneficial effects:

[0020] In this example, by installing a squeezing mechanism, the take-up roller takes up the fabric output from the main output end of the air-jet loom. As the fabric diameter increases, the electric push rod inside the protective shell is activated, and the moving end of the electric push rod gradually extends, driving the displacement frame to gradually approach the take-up roller. The pressure applied by the squeezing assembly continuously increases, compensating for the tension of the fabric and ensuring tension balance when the fabric is taken up.

[0053] In this embodiment, how to ensure tension balance during fabric winding, combined with... Figures 1 to 3 The specific implementation method is as follows: the take-up roller 2 takes up the fabric output from the output end of the air-jet loom body 1. As the diameter of the fabric continues to increase, the electric push rod 6 inside the protective shell 3 is activated.

Figure 3 The specific implementation method is as follows: the infrared pressure detector 7 monitors the fabric winding pressure, controls the extension or contraction of the moving end of the electric push rod 6, and controls the extrusion component 4 to strengthen or weaken the pressure.
