Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, and in particular to a fabric strip clamping device for a flatbed sewing machine. Background Technology

[0002] Computerized flatbed sewing machines are widely used as important production equipment in the sewing process of fabrics, leathers, and other materials in various industries such as garment manufacturing, home decoration, and automotive interiors. Traditional sewing machines usually use manual fixing or simple mechanical clamping devices when processing fabric strips. Manual fixing relies on the operator's manual operation, which can easily lead to operator fatigue during long-term work and affect the stability and accuracy of clamping. Although mechanical clamping devices improve the automation of clamping to a certain extent, mechanical clamping devices are usually structured with a fixed width, lacking flexibility and making it difficult to adapt to fabric strips of different sizes.

[0019] In practice, the fabric strip is placed above the work plate 102. The bidirectional lead screw 409 is rotated according to the width of the fabric strip. The rotation of the bidirectional lead screw 409 drives the two outer second sleeves 412 and the outer moving plate 413 to move.

The mounting block 206 and the first moving block 205 can be locked and fixed or disassembled and replaced by screws, which is convenient for personnel to perform maintenance and adjustment. When working, the first motor 204 is started to rotate the first lead screw 202. The rotation of the first lead screw 202 drives the first motor 204 to move. The movement of the first motor 204 drives the first moving block 205 at the outer end to move left and right. The movement of the first moving block 205 drives the computerized flatbed sewing machine 3 above to move left and right. At the same time, the computerized flatbed sewing machine 3 processes the fabric strip.

[0022] Reference Figure 3 , Figure 4The clamping mechanism 4 includes a second motor 401, one end of which is connected to a gear transmission box 402. A second lead screw 403 is connected inside the gear transmission box 402. Right-angle steering boxes 404 are connected to both ends of the second lead screw 403. A third lead screw 405 is connected to the upper end of the right-angle steering box 404. A first sleeve 406 is connected to the outer end of the third lead screw 405. A second moving block 407 is connected to the outer end of the first sleeve 406. A linkage frame 408 is connected to one side of the second moving block 407. A bidirectional lead screw 409 is connected inside the linkage frame 408.

The square plate 416 is connected to a second electric push cylinder 417 on one side, and the lower end of the second electric push cylinder 417 is connected to a pressure plate 418.

[0023] In practice, when clamping the fabric strip, firstly, based on the width of the fabric strip, the outer end of the linkage frame 408 is connected to the second moving block 407, and the inner part is connected to the bidirectional lead screw 409. The third motor 411 is started, driving the synchronous belt 410 via a rotating shaft. The bidirectional lead screw 409 rotates following the synchronous belt 410. The rotation of the bidirectional lead screw 409 drives the second sleeve 412 at its outer end to move in opposite directions. The movement of the second sleeve 412 drives the moving plate 413 connected to its outer end to move. The movement of the moving plate 413 drives the second electric push cylinder 4 at one end to move. 17. The opposing movement adjustment spacing corresponds to the width of the fabric strip. The second motor 401 is started, causing the second lead screw 403 to rotate via the gear transmission box 402. The second lead screw 403 drives the third lead screw 405 to rotate via the right-angle steering box 404. The rotation of the third lead screw 405 causes the first sleeve 406 to move downwards. The movement of the first sleeve 406 causes the linkage frame 408 on one side of the second moving block 407 to move downwards, driving the second electric push cylinder 417 downwards. The second electric push cylinder 417 then activates the pressure plate 418 to fix the fabric strip. In specific implementations, a protective cover can be installed on the outside of the lead screw to prevent it from being exposed. The protective cover often adopts a flexible, foldable structure or has a groove on the outside for the slider to connect and slide.
