Small-angle sewing device for automotive interior molded skin

Abstract

The invention relates to a small-angle sewing device for automotive interior molded skin, comprising: a small-head sewing machine, including a sewing machine frame, a small sewing machine head and an arc-shaped narrow sewing table structure arranged on the sewing machine frame correspondingly up and down, and a device A guide foot structure on the head of the small sewing machine and corresponding to the structure of the narrow sewing table; auxiliary feeding tooling, correspondingly matched with the small head sewing machine; the auxiliary feeding tooling includes a tooling arranged beside the sewing machine frame The base, the rotating drive structure arranged on the tooling base, the telescopic driving structure connected with the rotating driving structure, and the skin support wheel structure located at the end of the telescopic driving structure, the skin support wheel structure and the The structure of the narrow sewing table is matched accordingly. The present invention can solve the problem in the related art that wrinkles, breakage, imprints and other appearance defects are likely to occur when sewing the small-radius corner structure or the small-round proximal structure of the formed epidermis.

Description

technical field [0001] The invention relates to the technical field of automobile interior decoration, in particular to a small-angle sewing device for automobile interior molding skin. Background technique [0002] Suture design is becoming more and more common in automotive interiors. Suture design on the molded skin can produce soft interior products with exquisite craft texture and rich and beautiful stitch shapes. [0003] Affected by the performance and structure of the formed skin and the structure of the sewing machine, there are many restrictions on the shape of the sutures on the formed skin. The conventional sewing of the formed skin has a three-dimensional structure, and the skin needs to be placed on the sewing table first when sewing. However, the sewing table of the sewing machine is a planar structure, so when the skin cannot be spread out on the sewing table, the sewing cannot be carried out smoothly. The formed skin often has some trihedral structure, smal...
