[0002] A fabric folding device is a mechanical device or tool used to fold the edges of fabric. It is mainly used to improve folding efficiency and ensure edge neatness. It is suitable for processing fabrics of different sizes and materials. These devices usually include components such as constraint structures, folding strips or pressure plates. They achieve single or multiple layers of folding through mechanical or automated means, such as clamping the fabric into the slot to form a fold. The design of folding devices emphasizes flexibility and precise control, such as adjustable folding width and fixing mechanisms to prevent fabric slippage. They are widely used in the garment manufacturing industry.

[0003] Existing fabric hemming devices require manual hemming of the fabric before locking it in place. However, during manual operation, the fabric may detach from the hemming device, causing deviations during the hemming process. This necessitates manual repositioning of the fabric hemmed into the device, leading to decreased work efficiency. Therefore, a new fabric hemming device is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing fabric hemming devices, which require manual hemming of the fabric before locking it in place. Manual operation can lead to fabric slippage from the hemming device, causing deviations during the hemming process. This necessitates manual re-insertion of the fabric hemmed into the device, resulting in decreased work efficiency. Therefore, this invention provides a new fabric hemming device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fabric folding device includes a base plate, a fixing plate 1 fixedly connected to the upper part of the base plate, a slider 2 movably connected inside the fixing plate 1, a folding plate fixedly connected to the side of the fixing plate 1, a slider 1 movably connected to the side of the folding plate, a pressing column 1 rotatably connected inside the slider 1, a fixing plate 3 fixedly connected to the bottom of the slider 1, and a pressing column 2 rotatably connected inside the folding plate. By clamping the fabric with the pressing column 1 and the pressing column 2, the fabric is able to detach from the folding device when folding the fabric.

[0006] The above technical solution further includes: A second fixed plate is fixedly connected to the side of the first fixed plate, a movable plate is slidably connected to the outside of the second fixed plate, and a support block is rotatably connected to the side of the movable plate. By sliding the second fixed plate and the movable plate, and by rotating the movable plate and the support block, the system can adapt to sewing machines of different specifications.

[0007] The movable plate has a screw threaded connection to a knob one, which is movably connected to a fixed plate two. The movable plate also has a screw threaded connection to a support block. Tightening knob one fixes the fixed plate two to the movable plate, and tightening knob two fixes the movable plate to the support block.

[0008] The interior of slider two is rotatably connected to extrusion column one, and extrusion column one can rotate simultaneously inside slider one and slider two.

[0009] The size of the protrusions on the two sides of the slider is adapted to the size of the two openings inside the fixed plate, and the size of the slider is adapted to the size of the opening inside the fixed plate. The slider can be adjusted within the two openings inside the fixed plate.

[0010] The size of the protrusion on one side of the slider is adapted to the size of the two openings inside the folded edge plate, and the slider can be adjusted within the two openings inside the folded edge plate.

[0011] Both the first and second extrusion columns are wavy in shape, which allows the first and second extrusion columns to clamp the fabric tightly and prevent the fabric from slipping.

[0012] The shape of the fixing plate three is semi-elliptical, so that the fixing plate three can press the bottom fabric tightly.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the fabric is clamped by the cooperation of the first extrusion column and the second extrusion column, and the shapes of the first extrusion column and the second extrusion column are both wavy, so that the fabric is clamped and cannot slide in the opening formed by the first extrusion column and the second extrusion column. The fabric is squeezed by the fixed plate three at the bottom of the slider, so that the fabric on the bottom plate is squeezed, and the fabric is prevented from sliding due to the uneven width of the fold when the fabric is folded. 2. In this utility model, by the cooperation of the boss on one side of the slider with the two openings inside the folding plate, and by the cooperation of the boss on the other side of the slider with the two openings inside the fixing plate, the extrusion column can be adjusted to different heights, thereby adjusting the size of the opening formed by the extrusion column and the extrusion column, so as to adapt to fabrics of different thicknesses.
