Description

Technical Field

[0001] The utility model relates to the technical field of warp knitting machines, in particular to an adjustable pressing structure. Background Art

[0002] The warp knitting machine is mainly composed of a weaving mechanism, a comb bar transverse movement mechanism, a warp feeding mechanism, a pulling and winding mechanism, and a transmission mechanism. The transmission of the cloth within this distance cannot ensure sufficient tension, causing the cloth to be in a relatively loose state and requiring the cloth to be compressed.

[0003] For example, the Chinese patent application with application number 202221005671.3 provides an adjustable clamping structure for a warp knitting machine, which includes a bottom plate, a lifting mechanism and an adjustment mechanism. Two sets of vertical poles are fixedly installed on the top of the bottom plate, and a top plate is fixedly installed on the top of the two sets of vertical poles. The adjustable clamping structure for the warp knitting machine can compress the cloth by using the bottom plate, vertical poles, top plate, hydraulic rod, slider and lifting plate in coordination, and can compress multiple groups of cloth at the same time. However, the number of clamping frames in the clamping structure is fixed and cannot be adjusted according to actual needs. In addition, the clamping frames in the clamping structure cannot be used to compress cloth of different specifications, and the practicality is poor. Utility Model Content
