Embodiment Construction

[0020] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0021] See figure 1 , figure 2 , the present invention includes a fixed plate 1 with a hole for placing the cloth mechanism in the center, figure 1 The mesh cloth 3 has been placed in the supporting hole of the supporting cloth mechanism described in , and the shape and size of the setting hole should match the supporting cloth mechanism. On the fixed plate 1, the clamping device 2 is fixed around the hole for placing the cloth mechanism. The clamping device 2 includes a pneumatic slide base 20, and the pneumatic slide base 20 is connected to the pneumatic slide table 22. The pneumatic slide table 22 is connected with the pneumatic system. Connection, the pneumatic slide table 22 is connected to the clamping fixed plate 24, and one end of the clamping fixed plate 24 is connected to the cylinder rotating plate 25 by means of a hinge shaft,...

Abstract

The invention provides a three-dimensional (3D) cloth-wrapping tensioning mechanism for a seat backrest cloth-wrapping machine. The 3D cloth-wrapping tensioning mechanism is characterized by comprising a fixed plate, wherein a cloth-supporting mechanism mounting hole is formed in the center of the fixed plate; a clamping device is fixed on the fixed plate and at the periphery of the cloth-supporting mechanism mounting hole; the clamping device comprises a pneumatic sliding platform seat; the pneumatic sliding platform seat is connected with a pneumatic sliding platform; the pneumatic sliding platform is connected with a clamping fixed plate; one end of the clamping fixed plate is connected with a cylinder rotating plate through a hinged shaft; two ends of the cylinder rotating plate are fixedly connected with a lower clamping plate and a cylinder pedestal respectively; the cylinder pedestal is connected with a cylinder through a hinged shaft; a piston rod of the cylinder and the lower clamping plate are connected with a turnover plate respectively through a hinged shaft; and one side of the turnover plate is connected with an upper clamping plate. Compared with the traditional manual operation method, the 3D cloth-wrapping tensioning mechanism can tension net cloth and realizes different tensioning forces required at various positions of the net cloth. The 3D cloth-wrapping tensioning mechanism can save labor and can improve product quality and production efficiency.

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...
