Description

Technical Field

[0001] This utility model relates to the technical field of knitted fabric processing equipment, specifically a cutting device for knitted fabric processing. Background Technology

[0002] Knitted fabrics are fabrics formed by bending yarns into loops and interlocking them using knitting needles. They are widely used in clothing fabrics and linings, home textiles and other products. Knitted fabrics are soft, have good wrinkle resistance and breathability, and have great stretch and elasticity, making them comfortable to wear and therefore loved by consumers.

[0003] When processing knitted fabrics, it is necessary to cut and divide the large areas of connected fabric. However, when general cutting equipment is used, it may not have appropriate auxiliary devices to fix the fabric and change its tension, which may result in uneven cut surfaces and low cutting quality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model discloses a cutting device for processing knitted fabrics, including a processing table 1, an unwinding motor 2 at the upper end of the processing table 1, an unwinding shaft 3 at the output end of the unwinding motor 2, a knitted fabric body 4 wound on the unwinding shaft 3, a positioning frame 6 at the upper end of the processing table 1, a positioning shaft 5 rotatably mounted on the positioning frame 6 to limit the position of the knitted fabric body 4, and the positioning shaft 5 is located above the knitted fabric body 4.

[0025] The processing table 1 is provided with a fixed frame 7 and a first slot 15 above it. The fixed frame 7 is located above the first slot 15. The fixed frame 7 is provided with a base 12 below it. The base 12 is provided with a second drive motor 13. The output end of the second drive motor 13 is provided with a cutter 14 located inside the first slot 15. One end of the fixed frame 7 is provided with a first drive motor 9. The output end of the first drive motor 9 is provided with a threaded rod 10 that penetrates the top seat 8 and is threadedly connected to the top seat 8. The lower end of the fixed frame 7 is provided with a guide rod 11 that penetrates the top seat 8 and is slidably connected to the top seat 8.

[0026] The upper end of the fixed frame 7 is provided with a lifting component 18, the output end of the lifting component 18 is provided with a U-shaped rod 19, the two ends of the U-shaped rod 19 are provided with a limiting frame 20, and a limiting shaft 21 is rotatably provided on the limiting frame 20. The limiting shaft 21 is located on both sides of the first slot 15 and above the knitted fabric body 4, which limits the knitted fabric body 4 on the processing table 1.

[0027] The lifting assembly 18 has a vertically mounted lifting rod at its output end. The U-shaped rod 19 is fixed to the upper end of the lifting rod with screws, and the limiting frame 20 is fixed to both ends of the U-shaped rod 19 with screws.

[0028] The unwinding motor 2, the first drive motor 9, and the second drive motor 13 are all servo motors, and the lifting assembly 18 is a cylinder.

[0029] This knitted fabric processing cutting device achieves precise fabric cutting through the coordinated operation of multiple components. After the unwinding motor 2 starts, it drives the unwinding shaft 3 to rotate, causing the wound knitted fabric body 4 to gradually unfold. The positioning shaft 5 on the positioning frame 6 rolls above the fabric, guiding and limiting it to ensure the fabric is flat and adheres to the surface of the processing table 1. When the fabric is unwound to the required length, it is manually pulled to tighten it. Then, the lifting component 18 is activated, driving the U-shaped rod 19 to lower the two end limit frames 20, causing the limit shaft 21 to apply downward pressure to the fabric on both sides of the first slot 15, forming a stable clamping state.

[0030] During the cutting process, the second drive motor 13 drives the cutter 14 to rotate at high speed. At the same time, the first drive motor 9 drives the top seat 8 through the threaded rod 10, causing the fixed frame 7 to drive the cutter 14 to move laterally along the guide rod 11 in the first slot 15.

[0031] A support rod is provided on one side of the base 12, and a U-shaped plate 16 located in front of the cutter 14 is provided at the bottom end of the support rod. A second slot is provided in the middle part of the U-shaped plate 16, and the cutter 14 passes through the second slot. Multiple rollers 17 that contact the knitted fabric body 4 are rotatably arranged at the lower end of the U-shaped plate 16.

[0032] The roller 17 at the lower end of the U-shaped plate 16 on one side of the base 12 always keeps in contact with the fabric surface, providing support and rolling assistance as the cutter 14 moves forward, preventing the fabric from shifting during cutting due to elastic deformation. This linkage mechanism of "unwinding-positioning-tensioning-cutting" ensures the stability and cutting accuracy of the knitted fabric during the cutting process.

[0033] The roller 17 rolls in front of the cutter 14 to support the fabric, preventing stretching and deformation of the fabric at the moment of cutting through dynamic support, thus keeping the cut surface flat and neat. This mechanical structure requires no additional power source and optimizes the fabric tension solely through physical support.

[0034] The cutting blade 14 is made of high-speed steel and has been hardened to a hardness of ≥HRC60, ensuring long-term cutting sharpness.

[0035] In the description herein, it should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
