Abstract

The invention relates to a 3D wrapping cloth welding mechanism of a seat back wrapping machine for welding a mesh on a 3D back rest. The 3D wrapping cloth welding mechanism comprises an overall lifting cylinder; the overall lifting cylinder is connected with a fixing plate; the fixing plate is connected with a first welding device; a second welding device is arranged on a frame; cylinders are arranged on the frame bodies of the first welding device and the second welding device; a piston rod of the cylinder is connected with an ultrasonic wave welding head; a sliding rail pointing to a centredirection of the fixing plate is connected below the fixing plate; the sliding rail is connected with a sliding plate; the sliding plate is connected with the piston rod of a sliding plate cylinder; a cylinder body of a first welding head lifting cylinder is vertically connected on the sliding plate; the piston rod of the welding head lifting cylinder is hinged with the frame body of the first welding device; the piston rod of a second welding head lifting cylinder is hinged with the frame body of the second welding device, and the first welding device and the second welding device are staggered in groups. The 3D wrapping cloth welding mechanism, disclosed by the invention, can save welding time, precisely meet the demand of a 3D welding surface, meet the requirement of mass production and have good welding consistency.

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 back of the 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 tension shape of the 3D (that is, three-dimensional curved surface) backrest frame and the cloth backrest cushion. Learn different tensions. 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 mesh cloth in the previous step under clamping state; [0006] 4. Lay and compress the mesh cloth tensioned in th...
