Background

The heald frame is an important part in the loom and is a frame with heald penetrating rods and driving parts connected via upper and lower transverse beams and left and right side rails. After the heald frame is equipped with heald, the warp yarns threaded into the heald are integrated, and the heald frame is made to move up and down according to the program of the shedding device along with the motion of the heald lifting mechanism of the loom, so that the warp yarns are shed in layers to allow weft yarns to shuttle among the warp yarns, and the warp yarns are interwoven into fabrics with different patterns.

As shown in fig. 1 and 2, the heald frame fixing structure of the prior art includes an upper cross beam, a lower cross beam and a heald frame, wherein the upper cross beam and the lower cross beam are both provided with a U-shaped groove, and a screw hole is formed in one side wall of the U-shaped groove.

However, the tightening area of the fastening screw is small, the frame of the heald frame is easily scratched in the tightening process, in addition, the tightening force is not large enough due to the small tightening area, the heald frame can move up and down and left and right when the loom operates, the heald frame can slightly deviate under the action of inertia and warp, the fabric quality is influenced, and meanwhile, the scratching degree of the fastening screw on the heald frame is increased.

Based on this, the present disclosure is thus directed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a fixing structure of a heald frame, which is used for improving the fixing strength between a heald frame and an upper cross beam and a lower cross beam and reducing the damage of the fixing structure to the heald frame.

In order to achieve the purpose, the technical scheme of the utility model is as follows:

the utility model provides a fixed knot of heald frame constructs, the heald frame includes the heald frame and is located the crossbeam of heald frame upper and lower side, all be equipped with a plurality of U type grooves on the crossbeam, including pressing from both sides tight piece, the bottom surface outer wall in U type groove is fixed with the crossbeam, the internal face of one of them lateral wall in U type groove is the inclined plane to its outer wall slope, and the internal face of another lateral wall is the straight face, press from both sides the inclined plane that one of them lateral wall face of piece was laminated mutually with U type groove inclined plane, press from both sides the piece on with the relative lateral wall face in inclined plane be the straight face, the heald frame is installed in U type groove straight face and is pressed from both sides between the piece straight face.

Furthermore, the inclined angle of the inclined plane of the U-shaped groove is 12-18 degrees.

Furthermore, the clamping device comprises a connecting screw, wherein a long hole is formed in the clamping block, a screw hole is formed in the bottom surface of the U-shaped groove, and the connecting screw penetrates through the long hole and then is connected into the screw hole.

The utility model has the advantages that: the clamping block is used for increasing the jacking area of the heald frame, increasing the jacking area and reducing the scratch to the heald frame; the mode of the inclined plane and the screw is adopted, so that the clamping block can be conveniently plugged in and the clamping force can be conveniently controlled.

description of the reference symbols

The heald frame comprises a heald frame 1, a heald frame 2, a U-shaped groove 3, a screw hole 4, a jacking screw 5, a connecting screw 6, a clamping block 7 and a long hole 8.

Detailed Description

The present invention will be described in further detail with reference to examples.

In the fixing structure of the heald frame according to the present embodiment, as shown in fig. 3 to 5, the heald frame 1 includes a heald frame 2 and cross members provided on upper and lower sides of the heald frame 2. The upper crossbeam and the lower crossbeam of the heald frame 1 are provided with a plurality of U-shaped grooves 3, the outer walls of the bottom surfaces of the U-shaped grooves 3 are fixed with the crossbeam, the inner wall surface of one side wall of the U-shaped grooves 3 is an inclined surface inclined towards the outer wall surface thereof, and the inner wall surface of the other side wall is a straight surface. The fixing structure further comprises a clamping block 7, one side wall surface of the clamping block 7 is an inclined surface attached to the inclined surface of the U-shaped groove 3, and the side wall surface, opposite to the inclined surface, of the clamping block 7 is a straight surface.

During installation, the upper frame and the lower frame of the heald frame 2 are placed into the U-shaped grooves 3 on the upper cross beam and the lower cross beam, and then the clamping blocks 7 are placed, so that the straight surfaces of the clamping blocks 7 are close to the frames of the heald frame 2, and the inclined surfaces of the clamping blocks 7 are close to the inclined surfaces of the U-shaped grooves 3. Under the action of external force, the clamping block 7 is pressed downwards into the U-shaped groove 3, and due to the action of the inclined surface, the clamping force on the heald frame 2 is increased as the clamping block 7 moves downwards.

In the embodiment, for facilitating the pressing-in of the clamping block 7, the clamping block 7 is provided with a long hole 8, the bottom surface of the U-shaped groove 3 is provided with a screw hole 4, and the connecting screw 6 penetrates through the long hole 8 and then is connected into the screw hole 4. In use, the connecting screw 6 is screwed in to press the clamping block 7 downwards. Because the matching surfaces of the clamping block 7 and the U-shaped groove 3 are inclined planes, and the arrangement of the long hole 8 reserves a space for the horizontal transverse movement of the clamping block 7 relative to the connecting screw 6.

Preferably, in the present embodiment, the inclined plane of the U-shaped groove 3 is inclined at an angle of 15 °.

The above embodiments are only used for explaining the concept of the utility model, and not for limiting the protection of the utility model, and any insubstantial modifications of the utility model using this concept shall fall within the scope of the utility model.
