Method for antilocking for shuttle operation of three-dimensional textile machine

Abstract

A method of the anti-blocking of the operation of the shuttle of a three dimensional fabric knitting machine arranges the shuttle in the slot of a shuttle box and the shuttle can be controlled to slide to and fro along the slot of the shuttle box; while the shuttle box can slide to and fro under the pushing of a shuttle box push bar; at the moment, a tiny transmission intermission exists between the shuttle box push bar and the shuttle box during design and mounting; besides, the lower plane part of each shuttle box is internally embedded with a plurality of shuttle box magnets arrayed in certain distance; while the upper plane parts of the bases of the shuttle boxes corresponding to the position of each shuttle box magnet is internally embedded with A-position magnets of the bases of the shuttle boxes with the same quantity; B-position magnets of the bases of the shuttle boxes with the same quantity are also embedded at the position which is one traverse step length to the A-position magnets of the bases of the shuttle boxes. The poles of the A-position magnets of the bases of the shuttle boxes and the B-position magnets of the bases of the shuttle boxes are collocated with the magnets of the shuttle boxes to form an 'opposite attraction' state to finish the automatic accurate contraposition of the shuttle boxes in A-position and B-position by the mutual attraction. Consequently, during the operation of the knitting machine, each push bar of the shuttle box pushes corresponding shuttle box in a not very accurate and in place mode; while the accurate position is automatically adjusted and reached by the opposite attraction of the shuttle box magnets to the magnets of the bases of the shuttle boxes, thus improving the operation state of the knitting machine to lead the knitting machine to be well-off and accurate.

Description

Technical field [0001] The invention relates to a technology of a three-dimensional fabric knitting machine, in particular to a technology for preventing jamming of a shuttle of the three-dimensional fabric knitting machine. Background technique [0002] Three-dimensional woven fabric is a high-tech product that is being researched and developed at home and abroad in recent years. It is mainly used as a prefabricated part of special-shaped composite materials. The use performance of cracking, as a new material for key parts in military industry, national defense, aerospace and civil special fields, is getting more and more attention. [0003] The three-dimensional fabric weaving machine is the core processing equipment of this high-tech product. In terms of weaving methods, there are two typical applications: two-step three-dimensional weaving and four-step three-dimensional weaving. Among them, four-step three-dimensional weaving is widely used at present. For the conven...

Figure 2 shows the result of running operation that is often produced in practice: after each step of running in direction A, the shuttle box 2 and the shuttle 1 therein cannot ensure that each row or column is accurately arranged as a "row" and "column" In this way, the operation in the direction B will not be smooth in the future, and the phenomenon of "stuck" will easily occur, that is, it is easy to cause some shuttles 1 to be stuck due to the inappropriate movement along the "soil" shaped groove. Between two rows of shuttle boxes 2
