Description

Technical Field

[0001] The utility model relates to the technical field of sewing machines, in particular to a flatbed sewing machine with a limiting structure. Background Art

[0002] A flatbed sewing machine is a machine that uses a sewing thread to form a seam on the material to interweave or sew one or more layers of material together. It is usually divided into two uses: thin materials and thick materials. Flatbed sewing machines can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as leather, plastic, and paper.

[0003] When sewing fabrics on current flatbed sewing machines, workers are usually required to manually push one or more layers of fabric to the needle of the sewing machine for sewing. During sewing, workers are required to visually inspect the neatness of the fabric sewing and manually control the straightness of the fabric pushing. As a result, workers accumulate rich experience. However, the stitches are still prone to skew after sewing, which affects the sewing effect. Therefore, a flatbed sewing machine with a limit structure is proposed to solve the above problem.

[0029] A limiting member 4 for limiting the position of the fabric is provided on the workbench 2;

[0030] The lower end of the support plate 1 is rotatably connected to a moving wheel 5 , and a support member 9 for limiting the moving wheel 5 is provided on the support plate 1 .

[0031] In the present invention, the machine body 3 is a flatbed sewing machine in the existing conventional known equipment. Its working principle and specific structure of sewing fabrics are all in the existing known technology, so they are not described in detail in the text.

[0032] In an optional embodiment, the limit member 4 includes two guide rods 43, a group of guide grooves 42 are opened on the workbench 2, the guide rods 43 are fixedly connected to the inner side of the guide grooves 42, and each guide rod 43 is slidably connected to a group of guide blocks 44, a sleeve rod 45 is fixedly connected to the guide block 44, the inner side of the sleeve rod 45 is slidably connected to the support rod 46, the outer surface of the sleeve rod 45 is fixedly connected to the connecting rod 415, the end of the support rod 46 is rotatably connected to the limiting wheel 49, a connecting spring 413 is fixedly connected between the support rod 46 and the inner side of the sleeve rod 45, the inner side of the guide block 44 is fixedly connected to a support block 47, the upper surface of the support block 47 is fixedly connected to a stop block 48, the outer surface of the front sleeve rod 45 is fixedly connected to a spring telescopic rod 410, the spring telescopic rod 410 is fixedly connected to a placement block 411, and a fabric cylinder 412 is placed on the placement block 411.

[0033] In this embodiment, the limiting wheel 49 on the support rod 46 and the stopper 48 on the support block 47 can compress and guide one or more layers of cloth so that the cloth can be stacked neatly and pushed to the needle head of the machine body 3 in a straight line for sewing, without the need for manual accumulation of much experience, thereby improving the cloth sewing efficiency and sewing effect.

[0034] It should be noted that a set of guide grooves 42 are symmetrically distributed on the front and rear sides of the body 3, two sets of guide blocks 44 are symmetrically distributed on the two guide rods 43, and a plurality of placement grooves 414 for placing the fabric tube 412 are opened on the placement block 411. The placement grooves 414 are arranged in an inclined shape, and the number of placement grooves 414 can be set according to the number of fabric layers to be sewn.

[0035] The distributing cylinder 412 is supported in the placement groove 414 by a conventional cylindrical cross bar, and when the distributing cylinder 412 is replaced, the supporting cross bar is also replaced.

[0036] Among them, the end of the support rod 46 away from the sleeve rod 45 is L-shaped, the end of the L end of the support rod 46 is T-shaped, and the limiting wheel 49 is rotatably connected between the L end and the T end of the support rod 46, and the limiting wheel 49 is stably supported by the L end and the T end of the support rod 46.

[0037] In an optional embodiment, the end of the support rod 46 away from the sleeve rod 45 is L-shaped, the end of the L end of the support rod 46 is T-shaped, and the limiting wheel 49 is rotatably connected between the L end and the T end of the support rod 46.

[0038] It should be noted that the end of the U-shaped rod away from the sleeve extends into the workbench 2, and the front of the workbench 2 is provided with a number of limit grooves 41 that are compatible with the U-shaped rod. By adjusting the U-shaped rod to extend into the limit grooves 41 in different directions, the sleeve rod 45 for lateral movement adjustment can be limited and supported.

[0039] In this embodiment, since the guide block 44 supporting the sleeve rod 45 can slide horizontally on the guide rod 43, the U-shaped rod is pulled apart from the limiting groove 41, and after the sleeve rod 45 is driven to be adjusted horizontally, the reset U-shaped rod is extended into the limiting groove 41, which can support and limit the adjusted sleeve rod 45.

[0040] In an optional embodiment, the support member 9 includes a support frame 91 slidably connected to the support plate 1, a connecting block 92 is fixedly connected to the outer side of the support frame 91, a threaded rod 93 with one end passing through the connecting block 92 is rotatably connected to the support plate 1, and a threaded hole adapted for the threaded rod 93 is provided on the connecting block 92, so that the rotating threaded rod 93 can adjust the support frame 91 to move up and down along the vertical horizontal plane on the support plate 1 through the connecting block 92.

[0041] In this embodiment, the threaded rod 93 on the support plate 1 is used to adjust the support frame 91 to move downward to contact the ground, so as to limit the moving wheel 5 on the support plate 1 to improve the stability of the entire sewing machine during operation.

[0042] In an optional embodiment, a fixing rod 7 is fixedly connected to the back of the workbench 2 , an end of the fixing rod 7 is fixedly connected to a material guide plate 6 , and a collection box 8 is placed on the inner side of the material guide plate 6 .

[0043] In this embodiment, the material guide plate 6 located on the workbench 2 can block the sewn fabrics and guide them into the collection box 8 to improve the convenience of fabric collection.

[0044] The working principle in the above embodiment is:

[0045] After placing the fabric drum 412 on the placement block 411, the ends of the fabrics on one or more fabric drums 412 can be pulled to interweave or stack, and then the ends of the fabrics can be pushed through along the gap between the front limiting wheel 49 and the front supporting block 47. After being tightly pressed by the front limiting wheel 49 and blocked by the front stopper 48, the fabrics can be pushed to the needle head of the machine body 3 for sewing. After the sewn fabrics are further limited and guided along the gap between the rear limiting wheel 49 and the rear supporting block 47, the fabrics can be pushed and sewn in a straight line all the time. At the same time, the fabrics guided by the rear limiting wheel 49 are blocked by the guide plate 6 and can be guided along the guide plate 6 to the collection box 8 for collection.

[0046] When the fabric width needs to be adjusted, the U-shaped rod on the spring telescopic rod 410 can be pulled to separate from the limiting groove 41 on the workbench 2, and the placement block 411 can be moved to adjust the spacing of the sleeve rod 45. Then, the spacing between the limiting wheel 49 and the stop block 48 can be adjusted. When the U-shaped rod is re-extended to the limiting groove 41 in the corresponding direction, the sleeve rod 45 can be re-positioned and supported. After the spacing between the limiting wheel 49 and the stop block 48 is adjusted, the fabric tube 412 of different widths can also be replaced to the placement block 411.

[0047] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
