Description

Flexible edge closing mechanism

Technical field

The invention relates to a loom apparatus, in particular to a flexible edge-receiving mechanism.

Background technique

The edging device of the conventional looms is arranged on the heald frame of the front end, and the hemming edge is finished with the heald frame of the heald frame. Since the special double-layer fabric structure requires the edging device to be installed at the front end of the heald frame, The movement of the hemming device is required to follow the uniform movement of the end heald frame. However, the opening width of the rear heald frame is large and the hemming device is difficult to install, and the edger can be closed with a small opening, which seriously affects the hemming. The service life of the machine and the weaving efficiency of the weaving machine, and the existing electronic hinges are generally flat twisted edges, which cannot meet the requirements of the weaving of each layer of the multilayer fabric.

Summary of the invention

The technical solution adopted by the invention is: a flexible edge-receiving mechanism, comprising a hemming device, comprising: more than two pulling arms, a pulling rope, a pulling rope return spring, a guiding wheel, a staking bracket, a slanting guiding support The wheel, the sling reversing wheel, the sling sling, the closing return spring, the guiding wheel are respectively connected to the loom frame via the guiding wheel bracket, and the two or more pulling arms are respectively connected to the two sides of the gantry side multi-arm box Only on the upper arm, each pull arm is pulled with a drawstring, and the drawstring is wound around the guide wheel and pulled on the other side frame or side plate of the loom by the pull rope return spring, and the plurality of edge brackets Corresponding to the weaving edge position is connected to the frame, the edge bracket is correspondingly provided with the edge guiding support wheel and the sling reversing wheel for supporting the guiding rope, and the plurality of sling reversing wheels are connected with a plurality of edges. The sling, the end of the sling is pulled on the drawstring at one end, and the other end is vertically connected to the upper end of the ripper. The lower end of the reamer is connected to the base of the loom by a returning spring.

Further, the utility model comprises a rope reversing mechanism, wherein the rope is divided into a front rope and a rear rope, the rope reversing mechanism comprises a reversing bracket and a plurality of reversing shafts, and the reversing bracket is disposed on the upper position of the corresponding arm. On one side of the machine frame, the reversing bracket rotates and traverses a plurality of reversing shafts, and each of the reversing shafts is fixedly connected with two parallel reversing swing arms, and any of the front ropes is wound around a guiding wheel Afterwards, a reversing swing arm is arranged on the reversing shaft, and the other reversing swing arm on any one of the reversing shafts is correspondingly connected to one end of the rear drawstring, and the other end of the rear drawstring is pulled through the other guide wheel. The rope return spring is pulled over the loom frame or side panel.

Further, the guiding wheel, the leading edge guiding support wheel and the sling reversing wheel are all provided with guiding grooves corresponding to the pulling rope or the slinging rope.

Further, the utility model further comprises a bundled beam support, and the bundled beam support is arranged under the edge bracket to be connected to the loom frame, and the bundled beam mouth is provided with a plurality of edge bundles, and the edge of the rope is closed. Wear and close the inside of the beam.

During operation, a plurality of swing arms of the multi-arm box drive the heald frame to pull the front section drawstring through the upper arm, and the front section drawstring guides around a guide wheel and pulls a reversing swing arm on the reversing shaft. While the shaft rotates, the rear section draws the rope through the other reversing swing arm, and the rear section drawstring guide is supported on the hem guide support wheel and is reciprocated by the pull rope return spring after being wound by the other guide wheel. The rear-end drawstring reciprocates and pulls the reciprocating sling connected to the reciprocating rope at the same time, and the sling rope guides around the sling reversing wheel and then drives the reeder under the restraint of the sling beam bundle bracket. Under the action of the lowering return spring, the upper and lower reciprocating pulls are realized, and the plurality of edging devices complete the edging under the action of a plurality of rear slings, and the mechanism can be installed on the side of the heald frame near the sley. The opening requirement can be adjusted by the combination of the pull arm and the pull rope. The tension springs of the pull ropes can meet the elastic recovery, which is beneficial to reduce the hard work damage of the edger and prolong the service life, and is independent of the key components of the weaving machine and is easy to maintain.
