Description

Base needle in flat knitting machine

Technical Field

The utility model belongs to the technical field of knitting machine, specifically, relate to flat knitting machine, especially play end needle among the flat knitting machine.

Background

A bottom lifting needle in a flat knitting machine is arranged in a bottom lifting needle plate groove and comprises a needle sleeve and a crochet hook, and the crochet hook can slide in the needle sleeve groove. The needle sleeve is provided with a needle hook containing part, the hook needle is provided with a needle hook, the needle hook is arranged in the needle hook containing part in an initial state, when the bottom lifting needle participates in work, the needle hook can move downwards relative to the needle sleeve to hook yarns to play a role of traction until the main roller clamps the cloth cover, in order to avoid swinging of the cloth cover below the main roller, the auxiliary roller is influenced to clamp the cloth cover, and therefore the bottom lifting needle needs to upwards slide after the auxiliary roller clamps the cloth cover to withdraw from a working position.

The base needle has little change since the invention, and the closest prior art at present is still the technical scheme disclosed in chinese patent ZL92101555.0, and the structure of the base needle is as described in the above paragraph. When the crochet needle moves downwards, the needle hook and the needle sleeve are in an unclosed state, due to the reasons of uneven traction force of the main roller or the requirements of some textile tissues and the like, the draw-down amount of the cloth cover is different, when the draw-down amount is large, the yarn possibly breaks away from the needle hook, the traction force on the lifting bottom plate is uneven, the yarn which does not break away at the moment bears all original force, the more the yarn which breaks away, the larger the force borne by the yarn which does not break away, so that the bottom needs to be lifted again, and the yarn is wasted.

Disclosure of Invention

The utility model aims at overcoming the defects and providing a base needle in a flat knitting machine which is more reliable in hooking.

Therefore, the utility model discloses a technical scheme is like this: the bottom needle in the flat knitting machine consists of a needle sleeve and a bearded needle, wherein the needle sleeve is provided with two side walls and a needle sleeve groove formed by the two side walls so as to allow the bearded needle to slide in the needle sleeve groove; the head part of the bearded needle is provided with a needle hook, the head part of the needle sleeve is provided with a needle hook accommodating part, and the needle hook enters or leaves the needle hook accommodating part in the sliding process of the bearded needle; the method is characterized in that: the needle sleeve is provided with a secondary containing part below the needle hook containing part, and the secondary containing part is arranged on the opening side of the needle sleeve, is connected with the needle sleeve main body and has a certain gap with the needle sleeve main body.

Further, when the bearded needle slides to a certain position, the hook intersects with the hook receiving portion and the secondary receiving portion of the needle cover simultaneously on the side projection plane.

Furthermore, the secondary accommodating part is punched with the side wall of the needle sleeve to form a whole, and has an upward acute angle.

The utility model is provided with the secondary containing part, when the lifting needle hook needle moves downwards, the needle hook can be intersected with the secondary containing part of the needle sleeve to form a closed space with the needle sleeve, thus preventing the yarn from falling off; meanwhile, the secondary accommodating part has a gap with the main body, so that a space for the movement of the yarns is reserved as far as possible, and the unhooking of the yarns is not influenced when in follow-up needs. It can be seen that the hooking action of the utility model is more reliable and the structure is simple.

Drawings

Fig. 1 and 2 are schematic structural views of a prior art base lifting needle.

Fig. 3 and 4 are schematic structural diagrams of the first embodiment.

Fig. 5 is a schematic view of a needle guard according to one embodiment.

Fig. 6 is a partial schematic view of the second embodiment.

The drawings are numbered as follows: 1a, 1b, 1 c-needle guard; 2a, 2b, 2 c-crochet hook; 15a, 15b, 15 c-a hook receptacle; 16b, 16 c-a secondary locus of containment; 21a, 21b, 21 c-hook.

Detailed Description

See fig. 1, fig. 2. The prior art base needle is composed of a needle hub 1a having a needle hub groove for the hook to slide therein, and a hook 2a having a hook 21a at a head portion thereof having a hook receiving portion 15 a. When the needle 2a slides in the needle hub 1a, the hook 21a can move upwards into or downwards out of the hook receptacle 15 a.

See fig. 3, fig. 4, fig. 5. The base raising needle of the embodiment is composed of a needle guard 1b and a bearded needle 2b, the needle guard is provided with a needle guard groove for the bearded needle to slide in, the head part of the bearded needle is provided with a needle hook 21b, and the head part of the needle guard is provided with a needle hook containing part 15 b; a secondary receiving portion 16b is formed below the hook receiving portion 15b, and the secondary receiving portion is punched integrally with both side walls of the needle hub at the opening side of the needle hub, and has an upward acute angle. When the needle 2b slides in the needle hub 1b, the hook 21b moves down out of the hook receiving portion 15b and then into the area of the secondary receiving portion 16b, so that the thread cannot be pulled out.

See fig. 6. The embodiment comprises a needle sleeve 1c and a hook 2c, wherein the head part of the hook is provided with a needle hook 21c, and the head part of the needle sleeve is provided with a needle hook accommodating part 15 c; below the needle hook receiving portion 15c, there is a secondary receiving portion 16c, which is on the opening side of the needle hub. The secondary receiving portion 16c of this embodiment is formed by welding to both side walls of the needle hub. As can be seen more clearly in FIG. 6, at this point the hook 21c has not yet fully exited the hook-receiving portion 15c, the upper contour of the hook has intersected the lower contour of the hook-receiving portion, and the lower contour of the hook has intersected the tip of the secondary receiving portion, such that the gap between the secondary receiving portion 16c and the needle hub body 1c is an enclosed area 100.
