Description

Technical Field

[0001] This utility model relates to the field of fabric spreading machine technology, and in particular to an automatic fabric spreading machine for producing women's tops. Background Technology

[0002] In the production of women's tops, the fabric spreading machine is the core equipment connecting the fabric supply and cutting process. Its main function is to continuously and flatly spread the rolled fabric on the cutting bed according to the preset length and number of layers, providing a foundation for the accurate cutting of subsequent pieces. The quality of fabric spreading directly affects the pattern accuracy, fabric utilization rate and production efficiency of women's tops.

[0003] In existing technologies, it is inconvenient to tension the fabric during the fabric spreading process. Women's tops commonly use a variety of fabrics, including lightweight materials such as silk and chiffon, as well as knitted elastic fabrics and thin denim. Different fabrics have significantly different tension requirements. Traditional fabric spreading machines often have a single fixed tensioning mechanism with a narrow tension adjustment range and insufficient precision, making it difficult to adapt to the diverse characteristics of fabrics. For lightweight fabrics, excessive tension can easily lead to stretching deformation and edge fraying. For elastic fabrics, uneven tension can easily cause wrinkles. For heavy fabrics, it is difficult to provide sufficient tension to avoid traction slippage. Therefore, this utility model proposes an automatic fabric spreading machine for the production of women's tops to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes an automatic fabric stretching machine for the production of women's tops, which solves the problem of inconvenience in tensioning fabrics in the prior art.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: an automatic fabric spreading machine for producing women's tops, including a support frame, a fixing plate installed on the top of the support frame, first electromagnetic slide rails installed at both ends of the fixing plate, a first electromagnetic slider installed on the top of the outer side of the first electromagnetic slide rails, an mounting plate installed on the top of the first electromagnetic slider, a fabric clamp installed at one end of the mounting plate, a cutting mechanism provided on one side of the top of the support frame, a raw material roller installed on one side of the support frame, and a tensioning mechanism provided on the top of the raw material roller;

[0006] The tensioning mechanism includes a mounting base, a servo motor, a threaded rod, a threaded sleeve, a tensioning roller, and a limiting structure. The mounting base is installed at both ends of one side of the support frame. A servo motor is installed above one of the mounting bases. A threaded rod is installed inside the mounting base. The output end of the servo motor is connected to one end of the threaded rod. A threaded sleeve is provided on the outer wall of the threaded rod. A tensioning roller is installed at one end of the threaded sleeve.

[0007] A further improvement is that the tensioning roller has two roller bodies inside, and the two roller bodies are adapted to each other.

[0008] A further improvement is that the limiting structure includes a limiting rod and a limiting sleeve. The limiting rod is installed inside another mounting base, and a limiting sleeve is provided on the outer side wall of the limiting rod. One end of the limiting sleeve is connected to one end of the tensioning roller.

[0009] A further improvement is that the cross-section of the limiting rod is smaller than the cross-section of the limiting sleeve, and the limiting rod and the limiting sleeve form a sliding structure.

[0010] A further improvement is that the cutting mechanism includes a second electromagnetic slide rail, a second electromagnetic slider, a cutting blade, and a pressing assembly. The second electromagnetic slide rail is mounted above the support frame, and a second electromagnetic slider is provided at one end of the second electromagnetic slide rail. A cutting blade is mounted at one end of the second electromagnetic slider.

[0011] A further improvement is made in that: the pressing assembly includes a horizontal plate, an electric telescopic rod, a pressure plate, a guide hole, a guide rod, and a support plate. The support plate is installed on the inner side of the support frame, and the horizontal plate is installed on the upper part of the inner side of the support frame. An electric telescopic rod is installed at the top of the horizontal plate, and the bottom end of the electric telescopic rod extends to the bottom of the horizontal plate. A pressure plate is installed at the bottom end of the electric telescopic rod. A guide hole is formed through the interior of the horizontal plate, and a guide rod is installed inside the guide hole. The bottom end of the guide rod is connected to the top of the pressure plate.

[0012] A further improvement is that two guide rods are provided above the pressure plate, and the two guide rods are symmetrically distributed about the central axis of the pressure plate.

[0013] The beneficial effects of this utility model are as follows: By setting a tensioning mechanism at one end of the support frame, and utilizing the cooperation between the tensioning mechanism's mounting base, servo motor, threaded rod, threaded sleeve, tensioning roller, limiting rod, and limiting sleeve, the fabric tension can be precisely adjusted. This adapts to various materials such as silk, soft and wrinkle-resistant fabrics, elastic fabrics, and cotton and linen for women's tops, preventing the stretching and deformation of thin fabrics, wrinkling of elastic fabrics, and slippage of heavy fabrics. Simultaneously, it ensures the flatness of the fabric and the accuracy of interlayer alignment, reducing cutting errors. Furthermore, it is linked with processes such as feeding and cutting, eliminating the need for manual calibration and improving efficiency. This system improves production efficiency and product qualification rate. By incorporating a cutting mechanism, the system utilizes the cooperation of a second electromagnetic slide rail, a second electromagnetic slider, a cutting blade, a horizontal plate, an electric telescopic rod, a pressure plate, guide holes, guide rods, and a support plate. The pressure plate firmly secures the fabric, especially thin and multi-layered fabrics, preventing displacement and frayed edges during cutting.

[0025] Two guide rods 15 are provided above the pressure plate 13. The two guide rods 15 are symmetrically distributed about the central axis of the pressure plate 13. In use, the guide hole 14 and the guide rod 15 cooperate with each other to guide the pressure plate 13 when it moves, making the pressure plate 13 more stable when it moves.

[0026] Working principle: The operator first installs the raw material roller 10 on one side of the support frame 1, passes the fabric between the tension rollers 21, then passes it over the conveyor roller, and pulls it to the top of the support plate 16. The fabric clamp 6 then clamps the fabric. The first electromagnetic slider 4 is activated to move the mounting plate 5, and the fabric clamp 6 pulls the fabric. After the fabric cutting blade 9 is positioned appropriately, the electric telescopic rod 12 is activated. Under the limit of the guide hole 14 and the guide rod 15, the electric telescopic rod 12 moves the pressure plate 13, which presses and fixes the fabric. Then, the operation is started... The second electromagnetic slide rail 7 drives the second electromagnetic slider 8 to move, which in turn drives the cutting blade 9 to move. The cutting blade 9 is used to cut the fabric. Then the fabric clamp 6 is released to loosen the fabric. The fabric clamp 6 is then moved back to its initial position to pull the fabric again. When it is necessary to adjust the tension of the fabric, the servo motor 18 is started to drive the threaded rod 19 to rotate, which in turn drives the threaded sleeve 20 to move.
