Description

Shedding mechanism of loom

Technical Field

The utility model relates to a loom component, specifically speaking are loom shedding mechanism.

Background

The shedding mechanism of the weaving machine divides the densely arranged warps on the weaving machine into two groups which are mutually spaced, and the two groups of warps are alternately separated up and down to form a shed for a shuttle to pass through for weft insertion. The existing shedding mechanism of the loom comprises a plurality of structural components such as heald frames, healds, pull knives, drag hooks, heald lifting rods and the like, the shedding mechanism is complex in structure, and weft insertion gravitation needs to be increased to increase the speed of the loom, so that weft faults are more, the speed of the loom is limited, and the improvement of the productivity of the loom and the reduction of the production cost are not facilitated. In addition, the shedding mechanism causes loud noise and vibration of the loom.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a loom shedding mechanism to solve the problem that the action is complicated, the loom productivity is low and the vibration noise is big that current loom shedding mechanism causes because of the structure is complicated.

The utility model discloses a realize like this: the loom shedding mechanism has the structure that threading holes are respectively arranged at the positions of two sides of the top of a take-up frame, the two threading holes are positioned at the same height of the take-up frame and are symmetrically distributed by taking the central line of the take-up frame as the center line, the two threading holes are used for threading two adjacent warps on a loom, and the lower part of the take-up frame is fixed on a swinging shaft which drives the take-up frame to do reciprocating swinging motion.

The utility model discloses utilize the oscillating axle to drive the take-up frame and do reciprocating swing, make two through wires holes on the take-up frame rise and fall in a reciprocating manner to reach and drive two adjacent warp and play in turn and fall in order to form the shed, supply the shuttle to pass and the purpose of wefting insertion.

Set up on the loom the utility model discloses, can save a plurality of structural component such as current heald frame, harness wire, broach, drag hook and lifting rod, also avoided corresponding complicated actuating mechanism, only with the reciprocal swing control of oscillating axle, can realize the opening operation, not only simplified opening mechanism greatly, simplified the loom structure, also simplified actuating mechanism and action mode. Because the limit of the heald frame is not provided, the fabric can adapt to high-speed and wide-width weaving; because the shedding mechanism is simplified into the reciprocating swing of the swing shaft, the speed and the production efficiency of the weaving machine can be correspondingly improved, and the faults are reduced; because the arrangement of the heald frame is not adopted, the resonance of the impact motion is broken, so that the vibration of the loom is reduced, the noise is reduced, and the working environment of workers is improved.

In the figure: 1. a thread take-up frame; 2. threading holes; 3. a swing shaft; 4. fixing ring, 5, warp.

Detailed Description

Example 1:

as shown in fig. 1, the take-up frame 1 is a flat plate structure, and the upper portion thereof is rectangular and the lower portion thereof is inverted triangular. The top of the thread picking frame 1 is provided with a threading hole 2, and the threading hole 2 is arranged at the two corners of the top of the thread picking frame 1. The two threading holes 2 are positioned at the same height of the thread picking frame 1 and are symmetrically distributed by taking the central line of the thread picking frame as the center line.

The lower part of the take-up stand 1 can be fixed on the swing shaft 3 by various methods such as a fastener. Another feasible mode is that the bottom of the take-up stand 1 is connected with a fixing ring 4 for connecting a swinging shaft in a penetrating way, the fixing ring 4 and the take-up stand 1 are not in the same plane, namely the fixing ring 4 is axially sleeved on the swinging shaft 3 in a penetrating way, and the plane of the take-up stand and the plane of the fixing ring 1 form a certain included angle on the horizontal plane (figure 2). The inclined arrangement mode which enables the take-up stand to form a certain included angle on the horizontal plane can enable the two threading holes 2 on the take-up stand 1 to be just opposite to the two warps 5 which are adjacently arranged on the weaving machine, thereby enabling the two adjacent warps on the weaving machine not to be mutually influenced and to pass through the threading holes 2 on the take-up stand 1. When a plurality of shedding mechanisms are threaded on the swinging shaft 3 in a row and fixed, the warps on the weaving machine correspondingly pass through the threading holes on the take-up frames which are opposite to the straight lines of the warps, and all the warps can be divided into two groups of warps which are mutually spaced.

The swinging shaft 3 is driven by the driving mechanism to swing in a reciprocating manner, and drives the take-up frame 1 to swing in a reciprocating manner. When the swinging shaft 3 drives the take-up frame 1 to one end of the swing amplitude of the take-up frame, two groups of warps can be separated up and down; when the swinging shaft 3 drives the take-up frame 1 to the other end of the swing amplitude of the take-up frame, two groups of warp threads can be reversely separated up and down. In this way, by means of a simple pivoting movement of the shedding mechanism, it is possible to form a crossing shedding of the warp threads of the weaving machine and thus a shed. Therefore, the original complex shedding mechanism consisting of the heald frame, the heald rope and the like is thoroughly changed.

Example 2:

as shown in fig. 3, the take-up stand 1 is a V-shaped member bent with a wire, and the threading hole 2 is a loop provided at the top of each extension arm. The threading hole 2 may be a closed circular ring or a ring wound with a steel wire. The two threading holes 2 are positioned at the same height of the thread picking frame 1 and are symmetrically distributed by taking the central line of the thread picking frame as the center line.

The lower part of the wire picking frame 1 can be an arc section which is matched with the shaft surface of the swinging shaft and is fixed on the shaft surface of the swinging shaft 3 in a welding way; or a steel wire wound with a take-up stand is used, and a ring is wound at the bottom of the take-up stand 1 to form a fixed ring 4 capable of being connected with the swing shaft in a penetrating way. Similarly, the fixing ring 4 and the take-up frame 1 are not in the same plane, that is, the fixing ring 4 is axially sleeved on the oscillating shaft 3, and the plane of the take-up frame 1 and the plane of the fixing ring 1 form an inclined arrangement form with a certain included angle on the horizontal plane, so that the two threading holes 2 on the take-up frame 1 are just opposite to the two adjacent warps arranged on the loom, and the two adjacent warps on the loom pass through the threading holes 2 on the take-up frame 1 in a linear state. After the fixing rings on the plurality of opening mechanisms are threaded and fixed on the swinging shaft 3 in a row, all the warps on the weaving machine correspondingly penetrate through the threading holes on the take-up frames which are opposite to the straight lines of the warps, so that all the warps on the weaving machine can form two groups of warps which are mutually spaced. The swinging shaft 3 is used for driving the take-up frame 1 to do reciprocating swinging, so that the two threading holes 2 on the take-up frame 1 rise and fall in a reciprocating way, thereby achieving the purpose of driving two groups of warps to alternately rise and fall to form a shed for a shuttle to pass through for weft insertion.
