Description

Composite cloth moving frame structure of needling machine

Technical Field

The invention belongs to the technical field of needling machinery, and particularly relates to a composite cloth moving frame structure of a needling machine.

Background

The needling machine is developed from a needling machine, namely, related components which meet the requirements of needling of fabrics are additionally arranged on the basis of the needling machine, and typical examples of the related components are the composite cloth moving frame structure. In the actual use process, the full-computer servo control is usually adopted, all technical parameters and functions such as the needling frequency, the needling depth of a needling needle, the tension of a roller, the speed of the roller, needling, non-needling and the like can be set arbitrarily by a computer, and the method can be used for needling, carding, napping, compounding and the like of fabric fabrics with different weights and different styles in four seasons of spring, summer, autumn and winter, and can also be used for producing floor mats, wall mats, liners, shoe materials and non-woven fabrics with various patterns.

The cloth moving frame structure of the composite cloth can make the composite cloth in the overlapped state repeatedly move left and right and move back and forth as required in the process of needling by the needling mechanism.

Technical information of needling machines such as CN101492861B (automated multifunctional needling machine), CN102373579B (endless needling machine), CN102677397B (structurally modified biaxial needling machine), CN102677297B (structurally modified biaxial needling machine), CN102677398a (biaxial needling machine), CN102808290B (drum needling machine), CN106087288a (double-sided butt needling machine), CN105734836A (a low noise needling machine), CN106087259A (a high speed biaxial oriented ectopic butt needling machine) and CN106988023a (a small-diameter felt sleeve needling machine), etc. are visible in the published chinese patent literature.

Technical information which is essentially directed to the needling machine, although it appears under the name of the needling machine, such as CN207313868U (needling machine with lifting function), CN207313869U (spindle drive of needling machine), CN107500396U (dynamic balancing device of needling machine), CN207468846U (spindle and motor shaft synchronous belt expanding device of needling machine), CN207378152U (spindle head sealing device of needling machine) and CN207468848U (supporting net plate adjusting device of needling machine), etc. is also visible in the published chinese patent literature.

Because the needling of the fabric is performed on the composite cloth, the composite cloth is double-layer cloth or multi-layer cloth formed by overlapping upper and lower layers of cloth, upper, middle and lower layers of cloth or more layers of cloth, the lower layer of cloth is extracted to the surface layer of cloth by a needling needle to form a pattern, and the change of the needling depth of the needling needle determines that a certain lower layer of cloth is lifted upwards to the surface layer of cloth; in the needling process, the composite cloth is required to be continuously displaced left and right and back according to the technological requirements, so that the composite cloth moving frame structure forcing the composite cloth to move plays an important role on the whole set of needling machine, however, corresponding technical suggestions are not seen in the middle and outer patents and non-patent documents disclosed so far, and the technical scheme to be described below is generated under the background.
