Description

Technical Field

[0001] The invention belongs to the technical field of textile machinery, and in particular relates to a single-needle reed chain. Background Art

[0002] The main components of the sley are the screw nut drive mechanism in the cavity of the sley profile, the reed hinge attached to the outside of the profile, and the multi-toothed reed blade installed on the reed hinge. The defects of the existing reed blades and reed chains are as follows: the reed blade is a welded body of multiple reed needles and a reed blade bottom plate, but when a reed needle fails due to rust or other reasons, the entire reed blade needs to be replaced. The reed blade is installed on the reed hinge, not the reed needles are hinged to each other, and the distance between the reed needles at the transition of the two reed blades cannot be consistent with the distance between the reed needles on the same reed blade. The distance between the reed needles is very narrow, and it is very difficult to arrange the reed needles evenly on the reed blade bottom plate and weld them together, and the manufacturing cycle is long. The arrangement of the reed needles is often set to periodic helical teeth according to production needs. Because the number of helical teeth required by each user is different, it is difficult to pre-manufacture a large number of reed blades.

[0003] Therefore still be necessary to develop a kind of single needle type reed chain, in the hope that can solve above-mentioned technical problem. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects in the prior art and provide a single-needle reed chain.

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Example

[0027] like Figure 1-4 As shown, a single-needle reed chain comprises a plurality of reed needle blade groups 2 and a plurality of reed needles 1, wherein the plurality of reed needle blade groups 2 are connected by hinged means;

[0028] The reed needle piece group 2 includes, from top to bottom, an upper reed needle piece group 4, several spacers 7, a lower reed needle piece group 5, a lower needle stopper 3 and an intermediate turntable 6. The upper reed needle piece group 4 and the lower reed needle piece group 5 are fixed to the lower needle stopper 3 by the same bolt, and the bolts between the upper reed needle piece group 4 and the lower reed needle piece group 5 are provided with spacers 7. The purpose of providing the spacers 7 is to ensure that the reed needle 1 is vertically arranged on the reed needle piece group without tilting; a row of needle holes A8 equal to the number of reed needles 1 are evenly spaced on the upper reed needle piece group 4, and needle holes B9 matching the upper reed needle piece group 4 are provided at corresponding positions on the lower reed needle piece group 5. The reed needle 1 is detachably fixed to the reed needle piece group 2 through the needle holes A8 on the upper reed needle piece group 4 and the needle holes B9 on the lower reed needle piece group. The middle part of the lower needle block 3 is provided with a connection groove 10 matching the middle turntable 6, and the lower needle block 3 is fixed to the middle turntable 6 through the connection groove 10, and the lower reed needle group 5 is fixed to the middle turntable 6 through bolts. The adjacent ends of the two adjacent reed needle groups 2 share the same reed needle 1, and the two adjacent reed needle groups 2 are hinged through the shared reed needle 1. The upper reed needle group 4 includes two upper reed needles 8 arranged up and down, and the lower reed needle group 5 includes two lower reed needles 9 arranged up and down, and such an arrangement is convenient for the head-to-tail hinge connection between the adjacent reed needle groups.

[0030] In order to further effectively ensure that the reed needle is perpendicular to the surface of the reed needle plate group after installation and to facilitate the removal of the reed needle after installation, the present invention provides a single-needle reed chain, which also includes a plurality of locking needle pressure plate groups 11. The number of locking needle pressure plate groups 11 is equal to the number of reed needle plate groups 2. The locking needle pressure plate group 11 includes two locking needle pressure plates 13. The two locking needle pressure plates 13 are adjacent to each other end to end and are arranged in parallel between the upper needle block plate group 4 and the lower needle block plate group 3. A placement seam is left between the two locking needle pressure plates 13 for placing the reed needle 1. The two locking needle pressure plates 13 are both provided with slide grooves 14 with the same orientation. The slide groove 14 is used to place the spacer 7 provided on the bolt between the upper needle block plate group 4 and the lower needle block plate group 3. The height of the spacer 7 is greater than the thickness of the locking needle pressure plate 13, and the locking needle pressure plate 13 is made of elastic material.

[0031] The side surface of the locking needle pressing plate 13 is provided with a pushing portion 12 for facilitating the sliding of the locking needle pressing plate 13 relative to the spacer 7 .

[0032] The use method of the present invention is as follows: a single-needle reed chain is arranged on an external driving device, and the middle of the rotating discs at both ends of the single-needle reed chain is fixed to an external contraction mechanism by bolts;

[0033] When the reed needle 1 is in use for textile production, if one of the reed needles fails due to wear, the failed reed needle is directly pulled out and replaced with a spare reed needle;

[0034] When multiple reed needles of different lengths are arranged periodically on the reed chain and the periodicity needs to be adjusted, they can be pulled out and then reinserted to adjust the periodicity.
