Automotive trim formed skin small-angle sewing device

Abstract

The invention relates to an automotive trim formed skin small-angle sewing device. The device comprises the components of a small-head sewing machine and an auxiliary feeding tool. The small-head sewing machine comprises a sewing machine frame, a small sewing machine head and an arc-shaped narrow sewing table structure which are correspondingly arranged on the sewing machine frame up and down, anda guide pin structure which is arranged on the small sewing machine head and corresponds to the narrow sewing table structure; the auxiliary feeding tool is correspondingly matched with the small-head sewing machine; the auxiliary feeding tool comprises a tool base arranged beside the sewing machine frame, a rotation driving structure arranged on the tool base, a telescopic driving structure connected with the rotation driving structure, and a skin supporting wheel structure arranged at the end of the telescopic driving structure; and the skin supporting wheel structure is correspondingly matched with the narrow sewing table structure. The problem that in the prior art, when a small-radius corner structure or a small-rounded-corner near-end structure of a formed skin is sewn, wrinkles, damage, marks and other appearance defects are likely to be generated can be solved.

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...
