Abstract

The invention relates to a cloth wrapping machine for a seat backrest, which comprises a machine frame. A three-dimensional (3D) cloth wrapping and tightly pressing mechanism is arranged on one side of the machine frame, a 3D cloth wrapping and tensioning mechanism and a 3D cloth wrapping and annularly pressing mechanism are respectively arranged between an upper die and a lower die of the 3D cloth wrapping and tightly pressing mechanism, and a cloth supporting mechanism is arranged in the lower die. A 3D cloth wrapping and welding mechanism is arranged on the other side of the machine frame, the 3D cloth wrapping and annularly pressing mechanism is arranged on a moving and positioning mechanism, and the moving and positioning mechanism is installed on the machine frame and located under the 3D cloth wrapping and welding mechanism. The mechanisms are respectively connected with a pneumatic system and an electronic control system. The cloth wrapping machine for the seat backrest achieves mechanized automatic production of seat backrest cloth wrapping, can ensure different positions on backrest sieve cloth to meet quality requirements of different tensile force of ergonomics, and produced backrest cushion products are good in quality. The cloth wrapping machine for the seat backrest is high in production efficacy and capable of saving a great amount of labor power and working hours.

Description

technical field [0001] The invention relates to the technical field of cloth-wrapped backrest seats, in particular to a cloth-wrapping machine for wrapping the backrest of such a seat. Background technique [0002] Cloth-backed chairs are widely used in homes and various office spaces, and comfort is an important indicator of cloth-backed chairs. The comfort of the cloth backrest chair mainly depends on the 3D (that is, three-dimensional curved surface) backrest frame and the tensioned shape of the cloth backrest. The cloth backrest that meets the design requirements should have ergonomics at different positions on the backrest mesh Different tension. In the prior art, the back cushion of 3D form is artificially produced, and the steps of its production method are as follows: [0003] 1. First, design and manufacture a 3D backrest frame according to ergonomics; [0004] 2. Cut and unfold the mesh according to the shape and size of the 3D backrest; [0005] 3. Tension the...
