Description

Carrier rapier head shell for rapier loom

Technical Field

The utility model relates to a component on the rapier weaving machine, concretely relates to rapier is with sending latitude rapier head casing.

Background

The rapier loom is the most widely used shuttleless loom at present, and the rapier head is taken as a mechanical component of the rapier loom and comprises a weft insertion rapier head for weft insertion and a weft insertion rapier head for weft insertion. The rapier loom needs high-speed, high-automation and high-efficiency production, so that the speed of the rapier loom serving as a weft insertion rapier head is very important.

At present, the weft insertion rapier head is bulky and heavy, which has an influence on the running speed. Structurally, the rapier loom head comprises a shell of the weft feeding rapier loom head and a base plate arranged on the shell, and is not reasonable structurally when assembled and installed, the running resistance is obvious, and the base plate is not stable after running for a long time.

Disclosure of Invention

The utility model aims at solving the problem of not enough, and provide a small, the structure is more reasonable, and speed is fast to operate steady rapier head casing for rapier loom.

The utility model discloses the technical scheme who solves the problem as follows:

carrier rapier head casing for rapier loom, including sword shell and bottom plate, the bottom plate with be located the guide rail strip integrated into one piece of bottom plate side, its characterized in that: a transition surface is formed by the way that a bulge which takes the root of the guide rail bar as a starting point extends upwards and falls back to the other side edge of the bottom plate by a slope surface at the position close to the central line of the bottom plate is arranged above the bottom plate close to the guide rail bar, and the edge of the transition surface at the other side edge of the bottom plate is closer to the lower part of the bottom plate relative to the starting point of the bulge at the root of the guide rail bar; and mounting screw holes are formed in the range of the bulge above the bottom plate.

The protrusion is in a triangle shape with the top end being in an arc shape.

The rod shell is provided with a limiting groove used for matching and forming the raised part of the bottom plate, and the side surface where the limiting groove is located is flush with the side surface of the bottom plate after installation.

The utility model has the advantages as follows:

through setting the bottom plate transition face to protruding domatic weight that not only can reduce the bottom plate, can make the position that the bottom plate was installed on the pole casing improve at the side moreover, make it let the guide rail strip seem more slender on the integrated structure, it is faster replacing current rapier head service speed on former rapier weaving machine like this, stability is better.

In addition, the bottom plate and the guide rail strip are integrally formed, the firmness of the protrusion arranged above the guide bottom plate is better, the corresponding contact area is reduced, the probability of friction and yarn hanging of the whole body is reduced, and the service life is longer.

Description of the drawings:

FIG. 1 is a schematic view of the construction of a rapier head according to the present invention;

FIG. 2 is a schematic view of the structure of FIG. 1 from another angle;

fig. 3 is a schematic structural diagram of the bottom plate of the present invention;

fig. 4 is a schematic view of the structure of fig. 3 from another angle.

The specific implementation mode is as follows:

the present invention will be described in further detail with reference to the accompanying drawings.

Referring to a giver rapier shell for an rapier machine in fig. 1 to 4, comprising a rapier shell (1) and a bottom plate (2), on which a weft gripper mounting part (7) and a guide rail mounting part (8) are arranged, said bottom plate (2) being integrally formed with the guide rail (4) located at the side of the bottom plate (2), there being provided above the bottom plate (3) near the guide rail (4) a guide rail root as a starting point convex (10) extending upwards and at a position near the bottom plate (3) a center line falling back to the bottom plate (3) at the other side of the guide rail root as a transition surface, and the bottom plate (3) at which the guide rail root is located is further near the start point of the guide rail (5) to the guide rail (7) more proximate to the root of the guide rail (5) 5; an installation screw hole (9) is arranged in a range corresponding to the starting point of the base plate (3) up to the guide rail root (5).

The utility model discloses in when implementing, arch (10) can make the position that the installation screw hole corresponds relatively move up at the starting point of guide rail root (5), also be exactly the bottom plate that the bottom plate (3) corresponding on the sword shell (1) can be done shorter in the condition that guide rail (4) length is the same. And the transition surface (6) formed by the fall back of the slope of the other convex side does not affect the guiding function after installation, and the position of the installation screw hole (9) is designed so as to avoid the situation that the screw is fixed and loosened due to shaking when the transition surface (6) is in contact guiding.

Further, as an improvement to the embodiment, the protrusions (10) are in a triangular shape with the top end being arc-shaped.

In the utility model, the design of this arch (10) can strengthen the installation screw (peripheral plate strength) can make the bottom plate (2) more stable when installing on the sword shell (1), and guaranteed that the installation stability of bottom plate (2) is not influenced when weight reduces.

Further, as an improvement to the embodiment, the sabot is provided with a limiting groove (11) for matching a convex portion constituting the bottom plate (10), and the side (12) where the limiting groove (11) is located is kept level with the side after the bottom plate (3) is installed.

In the utility model, the setting of the limiting groove (11) can make things convenient for the installation of bottom plate (3), protruding (10) of bottom plate in the limiting groove (11), the installation screw hole (9) is directly opposite to the screw hole of bottom plate of the sabot (1) installation bottom plate (2). In addition, the influence of the vibration of the sword case (1) on the bottom plate (3) can be reduced through the adaptation of the limiting grooves (11), so that the bottom plate (3) is more compact after installation. And the side (12) and the side after the bottom plate (3) are installed are flat, so that the air resistance can be reduced when the rapier head shell moves.
