Description

Technical Field

[0001] This utility model relates to the field of garment processing technology, specifically to an elastic fabric stretching and positioning frame for garment processing. Background Technology

[0002] In the garment manufacturing industry, elastic fabrics, due to their excellent stretch and resilience, are widely used in the production of various apparel products such as sportswear and underwear. Before processing such as cutting, printing, and sewing, these fabrics need to undergo stretching and positioning treatment to ensure that the fabric is in a flat and taut state. This ensures the accuracy of subsequent processing and avoids problems such as dimensional deviations in cut pieces, misaligned patterns, or irregular seams caused by fabric slack. Therefore, the stability and accuracy of fabric stretching and positioning directly affect the final processing quality and production efficiency of the garment. Developing stretching and positioning equipment adapted to the characteristics of elastic fabrics has become an important demand for improving the level of garment processing.

[0003] Currently, the industry mostly uses mechanical or semi-automated equipment to perform stretching and positioning of elastic fabrics. While this can achieve basic stretching and fixing functions, the existing equipment may struggle to control the stretching force according to the fabric characteristics due to differences in the material (such as spandex blends, nylon elastic fabrics, etc.), weight, and elasticity coefficient of different elastic fabrics. When the stretching force is too small, the fabric cannot achieve the ideal tension, and subsequent processing is prone to wrinkles or positioning deviations. When the stretching force is too large, it will exceed the elastic limit of the fabric, causing irreversible deformation or even direct damage. This not only results in fabric loss but also affects production progress, making it difficult to meet the high-quality processing requirements of diverse elastic fabrics. Utility Model Content

[0004] The purpose of this invention is to provide a stretching and positioning frame for elastic fabrics in garment processing, so as to solve the problem mentioned in the background art that existing equipment may have difficulty in refining the stretching force according to the fabric characteristics.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A stretching and positioning frame for elastic fabrics used in garment processing includes a mounting frame, wherein positioning components are provided on both sides above the mounting frame. The positioning component includes two sliding bars on both sides and two fixed frames on both sides. Limiting ports are provided on both sides of the sliding bars, and tension sensors are provided on the outside of the limiting ports.

[0006] In a preferred embodiment of this utility model, a placement plate is provided on the upper inner side of the mounting frame, and a first electric push rod is provided on the inner side of the mounting frame, with the top telescopic end of the first electric push rod connected to the placement plate.

[0007] In a preferred embodiment of this utility model, limiting rods are provided on the front and rear sides of the bottom of the placement plate, and the limiting rods are slidably connected to the mounting frame.

[0008] In a preferred embodiment of this utility model, the mounting bracket is provided with sliding grooves on both sides, and the sliding strip is slidably connected to the sliding grooves.

[0009] In a preferred embodiment of this utility model, a threaded rod is rotatably provided inside the slide groove, and a threaded opening is provided on the inner side of the sliding bar, with the threaded rod and the threaded opening being threadedly connected.

[0010] In a preferred embodiment of this utility model, a motor is provided on the outside of the slide groove, and the output end of the motor is connected to a threaded rod.

[0011] In a preferred embodiment of the present invention, a second electric push rod is provided at the top of the fixed frame, and a fixing plate is provided on the bottom telescopic end of the second electric push rod, the fixing plate being located inside the fixed frame.

[0012] In a preferred embodiment of this utility model, sliding rods are provided on both sides of the bottom of the fixed frame, the sliding rods are slidably connected to the limiting port, and the tension sensor tension detection point is fixedly connected to the outside of the sliding rods.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0014] Beneficial effects: The fabric is laid flat on both sides of the fixed frames, with the fabric between the frames spread out. The second electric push rod then pushes the fixing plate, securing the fabric to the frames. Once the fabric is fixed, the motors on both sides drive the threaded rods to rotate. Through threaded transmission, the sliding strip and fixed frame move outwards, stretching the fabric to a taut state. As the sliding strip moves outwards, the tension is transmitted to the tension sensor through the fixed frames and sliding rods, detecting the tension. When a certain tension is reached, the motor stops rotating and locks to prevent the fabric from being damaged. Different safety tension thresholds can be preset according to the material characteristics of different elastic fabrics, adapting to the processing needs of various fabrics and improving the equipment's versatility.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please refer to Figures 1-4 This utility model discloses an elastic fabric stretching and positioning frame for garment processing, comprising a mounting frame 1, which is a mounting structure used to install other structures. A placement plate 11 is provided on the upper inner side of the mounting frame 1, and a first electric push rod 12 is provided on the inner side of the mounting frame 1. The first electric push rod 12 is a DTZ300 model. The top telescopic end of the first electric push rod 12 is connected to the placement plate 11, that is, the fabric is processed on the placement plate 11, and the placement plate 11 is extended and retracted by the first electric push rod 12, thereby adjusting the height of the placement plate 11 to facilitate processing by different workers. Limiting rods 13 are provided on the front and rear sides of the bottom of the placement plate 11. The limiting rods 13 are slidably connected to the mounting frame 1, so that the placement plate 11 slides vertically on the upper inner side of the mounting frame 1, thus ensuring its lifting and lowering and stability during processing. All electrical equipment in the structure is controlled by an external PLC intelligent controller. The PLC intelligent controller is an S7-200 SMART CPU ST40, which is a conventional technical means for those skilled in the art.

[0020] Positioning components are provided on both sides of the upper part of the mounting frame 1. The positioning components include two sliding strips 2 and two fixing frames 3. A second electric push rod 31 is provided on the top of the fixing frame 3. The second electric push rod 31 is a DTZ100 model. A fixing plate 32 is provided on the bottom telescopic end of the second electric push rod 31. The fixing plate 32 is located inside the fixing frame 3. The two sides of the fabric are laid in the fixing frames 3 on both sides, and the fabric in the middle of the fixing frames 3 is flattened. At this time, the fixing plate 32 is pushed by the second electric push rod 31, thereby fixing the two sides of the fabric in the fixing frame 3. The mounting frame 1 has a sliding groove 14 on both sides, and the sliding strips 2 are connected to the sliding groove. 14 is slidably connected. A threaded rod 21 is rotatably installed inside the slide groove 14. A threaded opening 22 is provided on the inner side of the sliding bar 2. The threaded rod 21 and the threaded opening 22 are threadedly connected. A motor 24 is provided on the outer side of the slide groove 14. The motor 24 is a 60ST-M00630 servo motor with a built-in braking structure. The output end of the motor 24 is connected to the threaded rod 21. After the fabric is fixed, the threaded rod 21 is driven to rotate by the motors 24 on both sides. Through the threaded transmission, the sliding bar 2 and the fixed frame 3 move outward, which can stretch the fabric and make it taut for easy processing. Limit ports 23 are provided on both sides of the sliding bar 2. A tension sensor 34 is provided on the outside of the limit port 23. The tension sensor 34 is an LC6203 model. The tension sensor 34 is electrically connected to the motor 24. Slide rods 33 are provided on both sides of the bottom of the fixed frame 3. The slide rods 33 are slidably connected to the limit ports 23, so that the fixed frame 3 and the sliding bar 2 are slidably connected. The tension detection point of the tension sensor 34 is fixedly connected to the outside of the slide rods 33. When the sliding bar 2 moves outward, since the fabric is fixed in the fixed frame 3, the tension will be transmitted to the tension sensor 34 through the fixed frame 3 and the slide rods 33 to detect the tension. When a certain tension is reached, the motor 24 stops rotating and locks to prevent the fabric from being damaged. The corresponding safe tension threshold can be preset according to the material characteristics of different elastic fabrics to adapt to the processing needs of various fabrics and improve the versatility of the equipment.

[0021] The working principle of this utility model is as follows: The fabric is processed on the placement plate 11, and the placement plate 11 is extended and retracted by the first electric push rod 12 to adjust the height of the placement plate 11, so that it can be processed by different workers. The two sides of the fabric are laid in the fixed frames 3 on both sides, and the fabric in the middle of the fixed frames 3 is flattened. At this time, the fixed plate 32 is pushed by the second electric push rod 31 to fix the two sides of the fabric in the fixed frames 3. After the fabric is fixed, the threaded rod 21 is driven by the motors 24 on both sides to rotate. Through the threaded transmission, the sliding strip 2 and the fixed frame 3 move outward, which can stretch the fabric and make it taut for easy processing. When the sliding strip 2 moves outward, since the fabric is fixed in the fixed frame 3, the tension is transmitted to the tension sensor 34 through the fixed frame 3 and the sliding rod 33 to detect the tension. When a certain tension is reached, the motor 24 stops rotating and locks to prevent the fabric from being damaged.
