Description
Technical Field
The invention belongs to the technical field of looms, and particularly relates to a pneumatic selvedge folding device of a rapier loom.
Background
The rapier loom, like an air jet loom, a projectile loom, etc., belongs to the category of shuttleless looms, and the shuttleless loom has the weft insertion characteristic of a weft insertion mechanism in the weaving process, so that selvedge is a burr, and can not naturally form a smooth edge in the weft insertion process like the shuttle loom, if the burr is not processed, the looking and quality of the fabric can be affected, and the burr is processed in the modes of cutting, flanging, sewing, etc., the labor and time are wasted, the material is wasted, and the production cost of the fabric of a textile manufacturer is increased. In view of this, the rapier loom is equipped with the above-mentioned selvedge folding-in devices in addition to weft yarn cutting devices such as CN204982245U (a rapier loom electronic weft yarn cutting mechanism), CN207619605U (loom rotary weft yarn cutting device), CN202809134U (a rotary electromagnetic weft yarn cutting device) and CN103757811a (an electronic weft yarn cutting device), and the like.
Technical information about pneumatic selvedge folding-in devices of rapier looms is not known in the published chinese patent literature, for example, CN103668718A recommends "a pneumatic weft yarn folding-in nozzle" and CN205556948U is provided with "a pneumatic selvedge folding-in device" and CN104630973B describes "a shuttleless loom short burr pure pneumatic selvedge folding-in device with adaptive mounting mechanism", etc., and none of these patents is limited to the exemplified technical teaching of integrating weft yarn cutting devices, i.e. weft cutting devices, with selvedge folding-in devices. Because, the weft shearing device and the folding-in edge device are integrated together, the weft shearing device and the folding-in edge device can show good modularization effect, simplify the structure, reduce the manufacturing cost and facilitate installation and debugging.
The disclosure of CN204151520U, a "built-in scissor type pneumatic tuck-in edge device" gives a teaching of integrating the weft scissor device with the pneumatic tuck-in edge device, but does not disclose the relevant components of the structural system of the weft scissor device. Since the "a pneumatic scissors and tuck-in edge device" disclosed in CN105803645a teaches that the pneumatic scissors (i.e., the components of the structural system of the weft scissors device) and the components of the structural system of the tuck-in edge device are assembled on the same scissors seat, the technical effects of the three aspects described in paragraphs 0018 to 0020 of the specification can be basically and faithfully exhibited. However, because the scissors are opened and closed by pushing the shifting fork (the shifting fork is arranged on the scissor shaft) by two plungers (the first plunger and the second plunger are respectively driven by the patent), and because the scissors are opened and closed by two independent air paths, and because the two plungers slide relatively to the scissor seat frequently and are equivalent to a single-acting air cylinder, the structure of the whole weft shearing device is complicated, the convenience in manufacturing and assembly is not facilitated, and the detection and the protection in daily use are not facilitated (see paragraphs 0032 to 0033 of the specification of the CN 105803645A).
