Description

Technical Field

[0001] The utility model relates to the technical field of air jet looms, in particular to a flat weaving and twisting weaving integrated device for looms. Background Art

[0002] Twisted fabric is a fabric woven entirely with leno tissue. Unlike ordinary three-primary fabrics (warp yarns are arranged in parallel), the warp yarns in the twisted fabric are divided into two systems (twisted warp and ground warp) twisted with each other and interwoven with the weft yarns. During weaving, the ground warp is fixed in place, and the twisted warp is sometimes on the right side of the ground warp, and sometimes on the left side of the ground warp to interweave with the weft yarns. When the twisted warp is transferred from one side of the ground warp to the other, the twisted and ground warp yarns are twisted with each other once, which increases the gap between the warp yarns and the weft yarns at the twisted position, forming yarn holes on the fabric. Therefore, the twisted fabric is also called mesh cloth. Plain weaving is the most common base fabric weaving method. The advantages of plain weaving are simple structure, convenient manufacturing, low cost, and easy promotion.

[0003] The patent with the authorization announcement number CN211112461U proposes a multi-flat and multi-twist device assembly for a water jet or air jet loom, a motor and a first eccentric wheel and a second eccentric wheel driven to rotate by the motor; the first eccentric wheel is connected to a front palm frame pull rod, and the rotation of the first eccentric wheel drives the front palm frame pull rod to move left and right; the second eccentric wheel is connected to the rear palm frame pull rod, and the rotation of the second eccentric wheel drives the rear palm frame pull rod to move left and right; the left end of the front palm frame pull rod is connected to the front palm frame, and the left end of the rear palm frame pull rod is connected to the rear palm frame; the rotation of the first eccentric wheel and the second eccentric wheel drives the front palm frame pull rod and the rear palm frame pull rod to move left and right relative to each other, and the relative left and right movement of the front palm frame pull rod and the rear palm frame pull rod drives the front palm frame and the rear palm frame to move left and right relative to each other. Using the technical solution of the utility model, the motor drives the rotation of the eccentric wheel to push the pull rod, so that the front and rear palm frames move left and right relative to each other, realizing the alternation of flat weaving and twisted weaving in the same fabric.

[0004] This patent cannot adjust the angles of the front and rear palm frame pull rods during twist weaving, so that the loom cannot perform twist weaving according to different needs. Utility Model Content

[0005] In order to overcome the above-mentioned defects existing in the prior art, the utility model provides a flat weaving and twisting weaving integrated device for a loom.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a flat weaving and twisting integrated weaving device for a loom, comprising two groups of loom side frames, the loom side frames are provided with two groups, a group of mounting plates are fixedly installed on the inner side of each group of the loom side frames, two groups of sliders are slidably installed on the mounting plates, guide frames are fixedly installed on the sliders, front palm frame pull rods are slidably installed up and down between the two front guide frames, and rear palm frame pull rods are slidably installed up and down between the two rear guide frames, and a lateral displacement driving mechanism is provided on the upper side of the right loom side frame.

[0007] Furthermore, two groups of slide grooves are arranged on the installation plate, and sliding blocks are installed on the slide grooves for sliding left and right.

[0008] Furthermore, the lateral displacement drive mechanism includes a servo motor, and two groups of servo motors are arranged at the upper end of the loom side frame. The power output shaft of each group of servo motors is fixedly connected to an eccentric wheel, and a connecting column is fixedly installed on the outer side of the eccentric wheel. A first pull rod is hingedly installed on the connecting column. The left side of the first pull rod can be slidably adjusted to install a second pull rod, and the left side of the second pull rod is fixedly installed on the guide frame.

[0009] Furthermore, a mounting block is fixedly mounted on the upper end of the loom side frame on the right side, and a servo motor is fixedly mounted on the mounting block.

[0010] Furthermore, a plurality of mounting holes are arranged at the upper end of the second pull rod, and a fastening bolt is arranged at the upper end of the second pull rod, and the fastening bolt can be matched with the mounting hole for installation.

[0011] The beneficial effects of the utility model are as follows: by adjusting the internal length of the first pull rod inserted into the second pull rod, the offset generated when the front palm frame pull rod and the rear palm frame pull rod are driven by two sets of servo motors are adjusted, and the two sets of servo motors are controlled separately to achieve independent control of the front palm frame pull rod and the rear palm frame pull rod, thereby achieving the overall adjustment of the angle of the loom during weaving, which is suitable for different products.
