Description

Technical Field

[0001] This utility model relates to the field of fabric straightening technology, and in particular to a device for straightening semi-elastic woven fabric. Background Technology

[0002] Semi-elastic woven fabrics are widely used in clothing, home textiles, and other fields due to their combination of elastic recovery and dimensional stability. However, during the production process, these fabrics often suffer from problems such as inconsistent width and uneven selvage due to tension fluctuations or localized stretching deformation, which seriously affect subsequent cutting or the quality of the finished product.

[0003] Chinese patent document CN222923419U discloses a device for straightening semi-elastic woven fabric, relating to the field of fabric wrinkle removal technology. This invention includes an operation box, on which a mixing component and a conveying component are respectively arranged. The mixing component is used for pre-wrinkling the woven fabric for subsequent ironing, and the conveying component is used for conveying the woven fabric after being shaped by the mixing component. A worktable is connected to the inner bottom of the operation box, and a drive source is connected to the inner top of the operation box. This invention uses a sealing gasket and a through-slot to prevent leakage of the wrinkle-removing agent. By controlling the downward movement of the concave block and the sealing gasket, the wrinkle-removing agent can be used to wet the first and second sponge blocks, facilitating contact with the upper surface of the woven fabric for application of the wrinkle-removing agent. This pre-wrinkle treatment of the woven fabric surface provides convenience for subsequent ironing and shaping. An ironing board facilitates ironing of the woven fabric located below it.

[0004] Because semi-elastic fabrics are sensitive to tension, the above-mentioned semi-elastic woven fabric straightening device only moves the fabric by pulling it with the winding equipment when in use. It cannot dynamically adjust the tension according to the tension requirements of different areas of the fabric, which can easily lead to local overstretching or loosening, affecting the overall effect of the fabric. Utility Model Content

[0005] The purpose of this utility model is to provide a semi-elastic woven fabric straightening device, which can solve the problem that, due to the sensitivity of semi-elastic fabric to tension, the above-mentioned semi-elastic woven fabric straightening device can only move the fabric by pulling it with the winding equipment during use, and cannot dynamically adjust the tension according to the tension requirements of different areas of the fabric, which can easily lead to local overstretching or loosening, affecting the straightening effect of the fabric.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a semi-elastic woven fabric straightening device, comprising a support frame, a tension adjustment mechanism, and a cooling mechanism. The tension adjustment mechanism is located inside the support frame and includes a threaded rod, an internal threaded block, a movable rod, a U-shaped bracket, and a pressure roller. The outer wall of the threaded rod is threadedly connected to the inner thread of the internal threaded block. The bottom of the internal threaded block is fixedly connected to one end of two sets of movable rods, and the other end of the movable rod is fixedly connected to the top of the U-shaped bracket. Pressure rollers are rotatably mounted on the inner walls of the front and rear sides of the U-shaped bracket. The cooling mechanism is located inside the support frame and includes an air inlet hood and a fan. A fan is fixedly mounted on the top inner side of the air inlet hood.

[0007] Preferably, the tension adjustment mechanism further includes a fixed plate, a hollow block, and a servo motor. The fixed plate is fixedly installed on the inner walls of the front and rear sides of the support frame. The hollow block is fixedly installed on the top of the fixed plate. The top of the inner side of the hollow block and the top of the fixed plate are respectively rotatably connected to both ends of the threaded rod. The servo motor is fixedly installed on the top of the hollow block. The output shaft of the servo motor is fixedly connected to one end of the threaded rod. The outer wall of the movable rod is slidably connected to the inside of the fixed plate. The downward pressure of the pressure roller is adjusted in real time through the pressure feedback detected by the tension detection roller. The fabric tension is dynamically adjusted according to the needs of different areas of the fabric to avoid excessive local tension causing fabric deformation or insufficient tension affecting the overall effect.

[0008] Preferably, the cooling mechanism further includes a mounting plate. The mounting plate is fixedly installed on the inner walls of the front and rear sides of the support frame. Two sets of air inlet hoods are fixedly installed on the top of the mounting plate. The air inlet hoods are connected to the bottom of the mounting plate to blow air onto the heated and leveled fabric, so that the fabric is cooled and shaped before being rolled up. This prevents the fabric surface printing, dyes, auxiliaries, and other substances from softening and sticking together, avoids the fabric temperature being too high after rolling up and burning the workers, and reduces safety hazards during operation.

[0009] Preferably, multiple sets of guide rollers are rotatably mounted on the front and rear inner walls of the support frame.

[0010] Preferably, tension detection rollers are rotatably mounted on the inner walls of the front and rear sides of the support frame. The tension detection rollers are commercially available products with pressure sensors evenly distributed on their surface for real-time detection of fabric tension. The PLC controller is connected to the servo motor.

[0011] Preferably, two sets of electric heating rollers are rotatably mounted on the inner walls of the front and rear sides of the support frame.

[0012] Preferably, the support frame has rectangular openings on the front, back, and bottom sides for ventilation and fabric adjustment.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The semi-elastic woven fabric straightening device uses a tension detection roller, a fixed plate, a hollow block, a servo motor, a threaded rod, an internal threaded block, a movable rod, a U-shaped bracket and a pressure roller in combination. The pressure feedback detected by the tension detection roller adjusts the downward pressure of the pressure roller in real time. The fabric tension is dynamically adjusted according to the needs of different areas of the fabric to avoid excessive local tension causing fabric deformation or insufficient tension affecting the overall effect.

[0015] (2) The semi-elastic woven fabric straightening device blows air onto the heated and leveled fabric by using a mounting plate, an air inlet hood and a blower in combination. This cools and shapes the fabric before it is rolled up, preventing the fabric surface from softening and sticking, avoiding the fabric temperature from being too high after rolling up and burning the workers, thus reducing safety hazards during operation.

The PLC controller is connected to the servo motor 403. Two sets of electric heating rollers 5 are rotatably installed on the inner walls of the front and rear sides of the support frame 1. Rectangular openings 7 are respectively provided on the front, rear, and bottom sides of the support frame 1 for ventilation and fabric adjustment.

[0024] Secondly, the tension adjustment mechanism 4 also includes a fixed plate 401, a hollow block 402, and a servo motor 403.

The servo motor 403 is fixedly installed on the top of the hollow block 402. The output shaft of the servo motor 403 is fixedly connected to one end of the threaded rod 404. The outer wall of the movable rod 406 is slidably connected to the inside of the fixed plate 401. The downward pressure of the pressure roller 408 is adjusted in real time through the pressure feedback detected by the tension detection roller 3.
