Description

The utility model relates to the equipment of weaving machines, in particular, to shedding mechanisms for the formation of triaxial fabric.

Known shedding mechanism for the formation of a triaxial tissue [RU 182016, U1, D03C 13/00, D03D 13/00, 02/26/2018], containing cantilevered heddles with eyes for the warp threads, mounted on housings that interact with the guide elements during longitudinal and transverse movement warp threads, where the longitudinal movement of the warp threads to form a shed, and the transverse movement of the warp threads to form a triaxial fabric.

The disadvantage of this technical solution is the relatively high complexity.

The closest in technical essence to the proposed one is a shedding mechanism for the formation of a triaxial tissue [RU 191225, U1, D03C 13/00, D03D 13/00, 05/24/2019], containing cantilevered heddles with eyes for the warp threads, mounted on bodies having an I-beam a profile interacting with the guide elements in the longitudinal and transverse directions of the warp threads, where the longitudinal movement of the warp threads to form a shed, and the transverse movement of the warp threads to form a triaxial fabric.

The disadvantage of the closest technical solution is also the relatively high complexity caused by the need to ensure high accuracy in the manufacture of transverse guide surfaces of shaft frames and cantilever heddles. This technical solution is also characterized by a relatively high complexity of adjustment, due to the requirement for high accuracy in the installation of cantilever heddles within the value of a small gap between them and maintaining it during operation.

All these factors reduce the reliability of the device, since violation of these requirements during the manufacturing process or adjustment during operation, which is characterized by a complex mechanical interaction of the elements of the mechanism with each other, can lead to malfunctions in the mechanism and the occurrence of malfunctions.

The objective of the utility model is to create a shedding mechanism for the formation of a triaxial fabric, characterized by structural simplicity and reliability of weaving equipment.

The desired technical result is to increase the reliability of work.

The problem will be solved, and the required technical result is achieved in a shedding mechanism for forming a triaxial fabric, containing cantilever heddles with eyes for warp threads, fixed on bases having an I-beam profile and interacting with guide elements during longitudinal and transverse movement of the warp threads, where the longitudinal movement of the threads warp is designed to form a shed, the transverse movement of the warp threads - to form a triaxial fabric, and, according to the utility model, the guide elements for the longitudinal movement of the warp threads are made in the form of channels with conical entries directed towards each other, and the guide elements for the transverse movement of the warp threads are made in the form of a closed loop, consisting of heddle carriers of heald frames and half rings placed at different levels with interpenetrating ends.

The utility model is illustrated by graphic images:

in fig. 1 - shedding mechanism for the formation of a triaxial fabric together with the warp and weft threads;

in fig. 2 - shedding mechanism for the formation of triaxial tissue, view A.

The shedding mechanism for forming a triaxial tissue contains console heddles 1 with eyes 2 for warp threads 3. Cantilever heddles 1 are fixed on bases 4 with an offset "e". The bases 4 are installed in the channels 5 of the movable bar 6. Channels 7 are placed on a fixed bar 8. Channels 5 and 7 have conical entries 9 directed towards each other, under which a cracker 10 is installed. machine. The base 4 is connected to the shaft frame 12 by heddle carriers 13. There are half rings 14 along the edges of the loom. The mechanism has a rotary device 15 with grippers 16. On the frame 11 of the loom, a batan 17 and a breast 18 are installed. The warp threads 3 form a shed of the weft thread 19.

Positions 20, 21, 22, 23, 24, 25 indicate the direction of movement of parts and components of the device.

Shedding mechanism for the formation of triaxial tissue works as follows.

According to his work, the guide elements for the longitudinal movement of the warp threads 3 are made in the form of channels with conical entries directed towards each other, and the guide elements for the transverse movement of the warp threads 3 are a closed circuit consisting of heddle carriers of shaft frames and half rings placed at different levels with interpenetrating ends, wherein one part of the cantilevered heddles is fixed on the housings with an offset relative to the other part, and the cantilevered heddles bodies are made flat.

When moving cantilever heddles 1 along channel 7 (direction 20), a shed is formed, into which weft thread 19 is laid. Conical entries 9 correct the position of cantilever heddles 1 before shedding.

Batan 17 nails the weft thread 19 to the edge of the fabric 26 (direction 24). The fabric is retracted by the commodity shaft (direction 25). The commodity shaft is not shown in the figure.

Capture 16 of the rotary device 15 takes the cantilever heddle 1 (direction 21).

The rotary device 15 moves the cantilever heddle 1 along the heddle carrier 13 until it engages with the half ring 14 and, after disengaging from the heddle carrier 13, transfers it to the other side of the shedding mechanism (direction 23) until it engages with the heddle carrier of another heald frame, the direction of the transverse movement of the warp threads changes. Thus, the movement of the console heddle 1 when changing the direction of the transverse movement occurs under the control of the half ring 14, and the transverse movement of the console heddles 1 occurs in each cycle of the loom (direction 22).

The two-tier arrangement of the cantilever heddles 1, the adjustment of the cantilever heddles 1 before shedding, the control of the movement of the cantilever heddles 1 when changing the direction of the transverse movement of the warp threads 3, and the flat design of the bodies of the cantilever heddles 1 reduce the dependence of the shedding mechanism on manufacturing accuracy and increase reliability. This ensures the achievement of the desired technical result.
