Description

Hook type bottom lifting needle of flat knitting machine

Technical Field

The utility model belongs to the technical field of the computer flat knitting machine technique and specifically relates to a flat knitting machine couple formula plays end needle.

Background

The computerized flat knitting machine that adopts at present plays the end needle and is mostly compound needle, and compound needle is formed by a plurality of needle slices welding, and this kind of compound needle structure is complicated, the processing cost is expensive and difficult processing, and above-mentioned compound needle still will be used with play end needle hook cooperation, leads to above-mentioned compound needle equipment troublesome, and installation effectiveness is not high, influences the use. In addition, the gaps between the needles of the compound needle are too large to allow the bottom-up needles to be closely arranged, and the gaps between the needles affect the stability of the steel wire passing through.

Therefore, a new type of base needle is urgently needed, wherein the needle head and the needle handle are integrally formed, and the base needle and the needle head penetrate through a fabric to ensure the stability of the steel wire penetration.

SUMMERY OF THE UTILITY MODEL

In order to overcome the problems in the prior art, the utility model provides a hook type base needle which is processed by integrated molding, is accurately positioned and installed and reduces the error rate.

The utility model provides a following technical scheme:

a hook type base needle of a flat knitting machine comprises a needle rod and a needle head, wherein the needle rod and the needle head are integrally formed, a conical needle hole is formed in the needle head, and the diameter of a needle inlet side hole is large and the diameter of a needle outlet side hole is small.

Furthermore, a V-shaped needle point is arranged on the needle head.

Furthermore, a stitch is connected below the needle head of the bottom lifting needle, so that the whole bottom lifting needle is Y-shaped, and the distance between the stitch and the needle rod is consistent with the thickness of the bottom lifting plate.

Furthermore, the lower part of the stitch is provided with a limiting bulge on the inner side, and the stitch is provided with a positioning hole for accommodating a limiting steel wire to pass through.

Furthermore, a limit groove is arranged at the tail part of the needle rod.

Adopt above-mentioned technical scheme, the utility model discloses following beneficial effect has:

1. the utility model discloses couple formula end-lifting needle integrated into one piece processing forms, appearance simple structure, workable, manufacturing cost is lower, and the location installation is accurate.

2. The connection between the needle and the needle is tight in use, and the stability of the steel wire passing through the needle hole is provided.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It is to be understood that the block diagrams and specific examples are set forth herein for purposes of explanation only and are not intended as limitations on the present invention.

Example 1

As shown in figures 1-5, the utility model provides a hook type base needle of a flat knitting machine, which comprises a needle bar A and a needle head B, wherein the needle bar and the needle head are integrally formed, a conical needle hole B-1 is arranged on the needle head, the diameter of the needle inlet side hole is large, the diameter of the needle outlet side hole is small, and a V-shaped needle point B-2 is arranged on the needle head. The tail part of the needle rod is provided with a limiting groove A-1 which can accommodate a limiting steel wire A-2 to pass through and be fixed on the rising bottom plate and is connected with the rising bottom plate into a whole to synchronously lift. The needle head is V-shaped, and the V-shaped needle head can easily penetrate through the fabric under the condition of higher fabric density, so that the bottom lifting mechanism is more stable and efficient. The upper portion of syringe needle is equipped with the steel wire hole for the interlude of steel wire, steel wire hole one-tenth "funnel" form taper hole, and it is big, play needle side aperture is little to advance needle side aperture, and each pinhole closely arranges and forms a passageway, holds the steel wire and alternates more stably smoothly between each play end pinhole through making the steel wire.

Example 2

As shown in figures 1-5, a stitch C is connected below the needle head of the bottom lifting needle, so that the whole bottom lifting needle is Y-shaped, and the distance between the stitch and the needle rod is consistent with the thickness of the bottom lifting plate. The distance between the limit bulge at the inner side of the stitch and the needle rod is slightly smaller than the thickness of the bottom plate, and the limit bulge is clamped on the bottom plate in an interference fit manner and cannot have clearance or loose. The bottom lifting needle is Y-shaped, the structure is more reasonable, and the needle rod and the stitch form a hook type to ensure that the bottom lifting needle is positioned more accurately. The inner side of the lower part of the pin is provided with a limiting bulge C-2, and the pin is provided with a positioning hole C-1 for accommodating a limiting steel wire to pass through. The bottom lifting needles are clamped and hung on the bottom lifting plate, so that a plurality of bottom lifting needles are connected into a whole, all the steel wire holes are positioned on the same horizontal line, the positions between the needle holes are accurate, and the installation consistency of the bottom lifting needles is better.

The above-mentioned embodiments only express the embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
