Quick sewing device for zippers
ActiveCN224199618Uincrease flexibilityImprove applicabilityWork-feeding meansStructural engineeringThreaded rod
The utility model relates to the technical field of zipper sewing machines, and discloses a rapid zipper sewing device which comprises a supporting seat, a sewing machine is arranged at the top of the supporting seat, a sewing adjusting assembly is arranged in the supporting seat, a limiting assembly is arranged at the top of the supporting seat, and the sewing adjusting assembly comprises a limiting groove. The inner wall of the limiting groove is slidably connected with a zipper splicing block, a limiting block sliding groove is formed in the inner wall of the limiting groove, the inner wall of the limiting block sliding groove is slidably connected with a limiting block, and the bottom of the limiting block is slidably connected to the surface of the zipper splicing block. By rotating the rotating handle, the rotating handle drives the two-way threaded rod to rotate on the inner wall of the supporting seat, so that the limiting block slides towards the inner wall of the limiting block sliding groove along the outer wall of the two-way threaded rod, the limiting block is separated from the surface of the zipper splicing block, the zipper splicing block loses limitation, and then the zipper splicing block is replaced. And the flexibility and the applicability of replacing zipper splicing blocks with different sizes are improved.

An outdoor tent fabric sewing device
ActiveCN224280700Uachieve stabilizationImplementation angleWork-feeding meansSpool-pin assembliesBall bearingElectric machinery
This utility model provides an outdoor tent fabric sewing device, relating to the technical field of outdoor product processing equipment. It includes a workbench with a sewing head fixedly connected to the top right side. A connecting groove is formed on the top left side of the workbench, and a conveying component is fixedly connected to the inner surface of the connecting groove. This utility model utilizes a rotating knob to drive a threaded column, which, through the threaded engagement, causes an annular pressure plate to move downwards via a sliding insert. A ball bearing, under the action of a spring, presses the fabric firmly, ensuring that the lower surface of the fabric is in contact with the rotating ring. An electric motor drives a feeding roller to achieve linear fabric conveying. The drive motor, through a bevel gear, drives the rotating ring to rotate within the annular groove, thereby adjusting the fabric angle. This structure solves the problems of easy fabric shifting and inconvenient angle adjustment in existing devices, making tent fabric sewing more precise, adapting to different sewing angle requirements, and improving operational convenience.
