Description

Technical Field

[0001] The utility model relates to the technical field of needle bed equipment, in particular to a needle bed assembly. Background Art

[0002] A warp knitting machine primarily consists of a weaving mechanism, a guide bar traversing mechanism, a let-off mechanism, a take-up mechanism, and a transmission mechanism. The process of knitting a fabric by feeding one or more parallel yarns in the warp direction onto all the machine's working needles simultaneously is called warp knitting, and the resulting fabric is called a warp knitted fabric. The machine that performs this type of warp knitting is called a warp knitting machine.

[0003] The main loop-forming components of a warp knitting machine include needles, guide needles, sinkers, and a pressure plate (for crochet machines). The needles are mounted in a row on the needle bed and move with it. The guide needles are mounted on a slatted plate to form a guide bar. The warp yarn passes through the holes of the guide needles and, as the guide bar moves, wraps around the needles. The coordinated movement of the needles, sinkers, and other loop-forming components creates the fabric.

[0004] At present, the needle bed crossbar adopts aluminum-magnesium alloy composite support. On the one hand, the material is heavy and the deformation is large during high-speed operation, which leads to frequent thread breakage and slow operation speed in the textile machine, reducing the yield rate of textile products. On the other hand, the needle bed crossbar and the aluminum-magnesium alloy needle bar are difficult to process and composite, and special equipment is required. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a needle bed assembly, including a crossbar body, and a solidified layer is provided on the upper end of one side of the crossbar body.

[0006] Preferably, the cross bar body is in the shape of a hollow rod.

[0007] Preferably, the middle portion of the crossbar body is hollowed out.

[0008] Preferably, the hollowing extends along the length direction of the crossbar body, and the hollowing is arranged parallel to the inner wall and the outer wall of the crossbar body.

[0009] Preferably, the length of the hollow portion is consistent with the length of the crossbar body.

[0010] Preferably, the crossbar body is formed by curing of carbon fiber composite material.

[0011] Preferably, the cured layer is made of epoxy resin.

[0012] Preferably, the solidified layer is provided with needle groove holes.

[0013] Preferably, the needle grooves are arranged on the solidification layer.

[0014] Preferably, the needle slot hole is adapted to the shape of the hanging needle and is used for hanging needles.

[0015] The technical effects and advantages of this utility model are:

[0016] 1. In the present invention, epoxy resin is directly used to cure and shape carbon fiber composite materials, thereby reducing the separate processing of aluminum-magnesium alloys used in the prior art, thereby improving the quality of finished parts.

[0017] 2. In the utility model, epoxy resin and carbon fiber composite materials are directly used to fix the molding, which reduces the use of aluminum-magnesium alloy separate processing in the existing technology, avoids the secondary bonding processing of the needle bar and the needle bed cross bar, and avoids the stress deformation caused by the fastening and compounding of the aluminum-magnesium alloy needle bar and the needle bed cross bar, thereby further improving the yield rate of textile products.
