Embodiment 1

[0020] like figure 1 , shown in Fig. 2, a kind of pneumatic jacquard device described in the present embodiment, it comprises heddle 7, return heald spring 8 and the lifting unit that drives the heddle 7 that warp yarn 9 promotes, and described lifting unit is made of cylinder 51 and A pneumatic unit composed of an air source 1 , the heald 7 is connected to the pneumatic piston rod 6 in the cylinder 51 , and the cylinder 51 is pneumatically connected to the air source 1 through the air circuit 4 . Healds 7 at different positions for lifting warp yarns 9 at different positions are respectively pneumatically connected to cylinders 51 at different positions, and the cylinders 51 at different positions form an integrated cylinder group module 5 . An electromagnetic reversing valve 31 and a pressure regulating valve 2 that control the execution of the cylinder 51 are provided on the connecting air path 4 between the cylinder 51 and the air source 1. The control input end of the ele...

Abstract

The pneumatic jacquard device designed in the present invention consists of harness wire, harness-back springs and the harness wire lifting unit which drives warp yarn lifting. Said lifting unit is a pneumatic unit including cylinder and air supply, harness wires are connected with the pneumatic piston rod in cylinder, and cylinder is connected with air supply through air course pneumatically. Said harness wire in different position which lifts warp yarn in different position can be linked with cylinder in different position pneumatically, and the cylinders in different position combines the integrated cylinder group module. The pneumatic jacquard device renews the mechanism of jacquard device, designs s single energy signal, namely, the control signals and execution signals are both pneumatic signals to simplify the structure and modularity, so the total elevation of jacquard device is homologous to ordinary loom. The invention uses cylinder and lifts warp yarn through harness wire, avoids the complex parts of motor, drive shaft, gear boxes, upgrade arm, broach and so on in mechanical lifting harness wire device and the device is greatly simplified.

Description

technical field [0001] The invention relates to a novel textile machine, in particular to a pneumatic jacquard device. Background technique [0002] Different design patterns of jacquard fabrics are mainly realized by different combinations of warp lifting and lowering. Comparing the existing technology with the traditional technology, the lifting of the heald depends on the mechanical force of the lifting knife, and the falling depends on the restoring force of the heald spring. The difference is that the control method of warp selection has changed from the traditional mechanical mechanism to the electronic-electromagnetic components, hence the name electronic jacquard machine, in fact, the main movement form of heald lifting is the same. [0003] Although electronic jacquard technology has developed to a fairly mature stage, it still exists: [0004] 1. The electromagnetic force of the control signal and the mechanical force of the execution signal are different physica...
