Drawings

FIG. 1 is an exploded view of a band yarn cutter for a textile machine according to the present invention;

fig. 2 is an assembly view of the yarn carrying knife for textile machinery of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

The band knife for textile machinery as shown in fig. 1 and fig. 2 mainly comprises a yarn guide component 1 and an auxiliary support component 2 which are clamped with each other.

The yarn guide assembly 1 comprises a slide 11, a limiting blocking piece 12, a first clamping strip 13 and a yarn guide piece 14; after the threading knife is mounted on the textile machine, the carrier sheet 11 is in a vertical state (as shown in fig. 2; the following relevant directions are defined according to the directions observed in fig. 2); the limiting baffle 12 is fixed at the edge of the surface of the carrier 11 (namely, at the lower edge of the carrier 11), extends towards the direction vertical to the carrier 11, and can be integrally formed or fixed by welding (when the limiting baffle 12 is fixed by welding, the end part of the limiting baffle 12 is in an angle shape, so that the welding surface of the limiting baffle is attached to the surface of the carrier 11); the yarn guide sheet 14 is formed at one end (i.e., the right end) of the carrier sheet 11, and they are generally integrated and in the same plane; one side (the side contacting with the carrier sheet 11, namely the inner side) of the yarn guide sheet 14 extends downwards to exceed the plane where the limit stop sheet 12 is located, and the other side (the side opposite to the former side, namely the outer side) of the yarn guide sheet is a concave arc side 141; one end of the first clamping strip 13 is fixed to the yarn guide 14 (at the inner side of the yarn guide 14, so that the bottom edge of the first clamping strip 13 is aligned with the lower end of the inner side of the yarn guide 14, i.e. the bottom edge of the yarn guide 14 is aligned with the bottom edge of the first clamping strip 13) and thus perpendicular to the yarn guide 14 for insertion into a corresponding slot of a textile machine.

The auxiliary supporting component 2 comprises a first clamping sheet 21 contacted with the surface (the end surface far away from the first clamping strip 13) of the limit stop 12, a second clamping sheet 22 intersected with the edge of the first clamping sheet 21 and vertical to the first clamping sheet, and a second clamping strip 23 formed at the joint of the first clamping sheet 21 and the second clamping sheet 22 and in the same plane with the second clamping sheet 22, so that the second clamping strip 23 is arranged at a distance from the first clamping strip 13 and extends in the same direction, and the second clamping strip 23 is correspondingly inserted into a slot of the textile machine.

In this embodiment, a notch 121 is formed in one end of the limiting baffle 12, which is far away from the yarn guide piece 14, and the auxiliary support component 2 is correspondingly clamped at the notch 121; specifically, a joint (one end not provided with the second clamping strip 23) of the first clamping piece 21 and the second clamping piece 22 is provided with a clamping seam 24 inwards, which is matched with the limiting blocking piece 12, so that the yarn guide assembly 1 and the support assembly 2 are clamped. In use, the threading knife rotates synchronously with the rotating mechanism of the textile machine, so that the concave arc edge 141 of the threading knife is in contact with the yarn and brings the yarn into the corresponding yarn nozzle.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
