Bottom-needle raising mechanism of computer plain flat knitter

Abstract

The invention relates to a lift needle of a computer flat knitting machine, belonging to the field of needle means, which comprises a hook which has a hook head at the summit and a hook butt at the bottom, a needle sleeve which has a needle insert butt at the offset lower end, matches with the hook, and ensure the hook move upward and downward; wherein, a first winding slot is arranged at the topof the hook corresponding with the bottom of the hook head; the needle sleeve has a hook groove for the hook moving upward and downward; a second winding slot inclined staggered and communicated withthe hook groove is arranged on the top of the needle sleeve; the first side on the top of the needle sleeve is out of the second side. The hook head matching with the second winding slot can control the yarn effectively, and the first side is out of the second side which is not only beneficial for the yarn to enter the second winding slot, but also avoids the yarn getting out of the second winding slot. The lift needle of a computer flat knitting machine has the advantages of simple structure, and easy processing and assembling.

Description

technical field [0001] The invention relates to a bottoming needle structure of a computerized flat knitting machine, which is installed on a needle lifting plate. The needle lifts up to the mouth of the knitting mechanism to start the needle, and belongs to the technical field of knitting needle components. Background technique [0002] The starting needle is also called the starting needle and the crochet hook. The more common starting needle structure is composed of Figure 5 As shown, it is composed of a needle hook 1 and a needle sheath 2 which are slidably matched with each other, that is, the needle hook 1 is movably arranged in the needle sheath 2 . The needle hook head 11 of the opening needle of this structure is processed very delicately (delicate), therefore exposes the deficiency that is easy to break during use, and the control property to yarn is poor, and the processing technology requirement is very harsh in addition.

AI Technical Summary

Problems solved by technology

The needle hook head 11 of the opening needle of this structure is processed very delicately (subtle), so it exposes the deficiency of being easy to break during use, and the control of the yarn is poor, and the processing technology is very demanding.

[0003] Image 6 It is another kind of bottoming needle structure that is more common at present. It is composed of needle hook 1 and needle cover 2. It can implement a closed tube bundle for the yarn, and the phenomenon of yarn take-off can be reduced, but it is easy to push the yarn to the outside, causing damage to the yarn. The influence of the needle quality, and when the hook head 11 of the hook 1 is worn, the yarn will escape from the closed mouth

[0004] Chinese Patent Authorization Announcement No. CN2856082Y recommends a kind of crochet hook, from the contents of its description and in conjunction with Fig. 7 of the accompanying drawing of the patent description as can be seen, because it is the front and rear needle body (equivalent to the needle cover) and the needle core (equivalent to The needle hook) is hinged with a pin shaft, so the number of parts is as many as four, resulting in time-consuming assembly and complicated structure; The groove wall has reached a state of matching, but it is still not enough to fully control the yarn, so there is a high probability of yarn falling out
