Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sewing machines, in particular to a mesh guiding clamp for a sewing machine, a sewing machine and a sewing process. BACKGROUND

[0002] In the field of garment production, the sewing quality of the fabric edge directly affects the durability and aesthetics of the product. At present, after the fabric (cotton, hemp, knitted fabric, etc.) is sewn, the thread ends at the edge are prone to looseness and scattering after washing and rubbing, resulting in damage to the fabric edge and thus shortening the service life of the product. Since the mesh has high toughness and tensile resistance, it can be wrapped with a layer of mesh at the edge during sewing of the fabric edge and sewed together with the needle thread to enhance the toughness and tensile resistance of the fabric edge. In this way, a protective layer can be formed at the edge of the fabric after sewing, which can effectively lock the thread ends and solve the above problems.

[0003] However, when sewing the mesh on the fabric, the following problems exist: 1. Since the mesh is light and thin and prone to deformation, it is difficult to accurately control its direction during manual sewing, and the protective layer cannot completely wrap the fabric, which cannot fully play its reinforcing role. 2. In order to effectively wrap the fabric edge before sewing, the mesh needs to be pre-folded (folded inward) before being sewn with the fabric, but the folding force and angle are uneven, resulting in large differences in the folding shape of the mesh in the same batch of products, which cannot be uniformly sewn on the fabric, thereby affecting the aesthetics of the product. SUMMARY

[0004] In view of this, the purpose of the present application is to provide a mesh guiding clamp for a sewing machine and capable of folding the mesh inward and uniformly sewing it on the fabric.

[0027] Further, the edges on both sides of the guide groove 3 can be stuck with anti-slip silicone strips (adapted to the special material of the net to increase friction), which can prevent the net from sliding longitudinally when being dragged by the sewing machine.

[0028] In the present solution, the bending amplitudes of the upper clamp plate 2 and the lower clamp plate 1 gradually increase from front to back, so that the shape of the inlet end of the guide groove 3 is designed as a gentle arc, and the shape of the outlet end is close to a semicircle. This not only facilitates the entry of the net into the guide groove 3, but also enables the net to be smoothly sent out from the guide groove 3 during sewing.

[0029] In the present solution, the length of the upper clamp plate 2 is shorter than that of the lower clamp plate 1, and the rear end of the upper clamp plate 2 is aligned with the rear end of the lower clamp plate 1. In this way, a gap is formed above the front end of the guide groove 3, which facilitates the net to be pasted to the upper side of the lower clamp plate 1 and extend into the guide groove 3.

[0030] In the present solution, the rear sides of the upper clamp plate 2 and the lower clamp plate 1 are inclined surfaces, so that the outlet end of the guide groove 3 is an inclined guide surface, which facilitates the net to be folded in half after extending out of the guide groove 3 and pasted to the edge of the fabric.
