Description

Metal heald

Technical Field

The utility model relates to the technical field of weaving, in particular to metal heald.

Background

Healds are parts on a loom which drive warp yarns to move up and down to form sheds. The healds are threaded on the heald rods in the heald frame. The motion laws of the warp yarns passing through the same heald frame are the same. On a jacquard loom, harness cords and head lines are connected with vertical hooks, and the motion laws of warps controlled by the same vertical hook are the same. The beautiful heald for weaving the leno fabric has two types of line and metal heald. The metal heald is durable and has wide variety adaptability.

The patent with publication number CN215051009U discloses that the circular weaving machine is with novel flat metal heald, adopts the technical scheme that the both ends of flat metal heald body directly inwards buckle and form the bending part, carries out couple formula connection through the bending part when using to effectively reduced the wearing and tearing that the plastics axle received, also made to overhaul and change more convenient.

However, the inventor thinks that the technical scheme has the following problems: due to the adoption of hook type connection, the connection effect is unstable, the bent part can be separated from the plastic shaft in the working process, at the moment, the machine is stopped to hang the bent part again, and the machine is started for production, so that the production efficiency is greatly influenced.

SUMMERY OF THE UTILITY MODEL

The application provides a metal heald can solve the unstable problem of the connection effect that the couple formula is connected.

The application provides a metal heald, which comprises a metal heald body, wherein bent parts at two ends of the metal heald body are respectively provided with a clamping part; each clamping opening part comprises two clamping blocks and two miniature springs; each clamping block is connected to the bending part through one miniature spring and is positioned on the front side and the rear side of the opening of the bending part; in each of the snap-apart portions, a minimum distance between two of the snap-fits is greater than a diameter of the plastic shaft.

By adopting the technical scheme, the clamping part can limit the plastic shaft in the bending part to a certain degree, so that the plastic shaft cannot be separated from the bending part in the working process. When the metal heald body needs to be taken down, the metal heald body is pulled, and the miniature spring is compressed under the action of human force, so that the plastic shaft is separated from the metal heald body.

In one embodiment, one rubber layer is disposed within each of the two bent portions.

By adopting the technical scheme, the bent part is in contact with the plastic shaft through the rubber layer, so that the abrasion of the plastic shaft in the contact process can be effectively reduced.

In one embodiment, in the clamping part at the upper end, two surfaces, which are closest to each other, of the two clamping blocks are inclined towards the direction that the lower ends of the two clamping blocks are close to each other; in the clamping opening part positioned at the lower end, two surfaces closest to each other between the two clamping blocks are inclined towards the direction that the upper ends are close to each other.

By adopting the technical scheme, the metal heald body is pulled to enable the plastic shaft to be separated, so that the plastic shaft is more convenient.

In one embodiment, the fixture block is made of plastic.

By adopting the technical scheme, the plastic is light in weight and economical in price.

In one embodiment, a wear-resistant square ring is arranged in the square through hole of the metal heald body.

By adopting the technical scheme, the wear resistance of the square through hole in the metal heald body can be effectively improved.

In summary, in the present application, compared with the prior art, the metal heald has the beneficial effect of effectively organizing the plastic shaft to be separated from the metal heald body in the working process.

Detailed Description

The following description will further explain the embodiments of the present invention with reference to the accompanying drawings; the following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention. And the described embodiments are a few embodiments, not all embodiments, of the disclosure. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the disclosure without any inventive step, are within the scope of protection of the disclosure.

Unless otherwise defined, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure belongs. The use of the word "comprising" or "comprises", and the like, in this disclosure is intended to mean that the elements or items listed before that word, include the elements or items listed after that word, and their equivalents, without excluding other elements or items. "upper", "lower", "front", "rear", and the like are used only to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

Referring to fig. 1, a metal heald includes a metal heald body 1, two ends of the metal heald body 1 are bent inward to form bent portions 2, and a square through hole 3 is formed in the middle of the metal heald body 1.
