Description

Carbon fiber jacquard guide bar and warp knitting machine

Technical Field

The utility model relates to a spinning machine field, concretely relates to merchant card tricot machine field, in particular to carbon fiber merchant card sley bar and tricot machine.

Background

Jacquard warp knitting machines are a type of jacquard device, and the pattern fabric formed by such devices is called warp-knitted jacquard. The jacquard warp knitting machine is defined in that each guide needle on a jacquard guide bar is driven by a piezoelectric element of the warp knitting machine to perform independent additional transverse movement. The jacquard warp knitting machine is different from a common warp knitting machine in that each guide needle of a jacquard guide bar can independently pad yarn in a certain range, patterns with unlimited sizes can be knitted, each guide needle of the common guide bar cannot independently generate deviation, and the pad yarn movement of all the guide needles is the same. The jacquard warp knitting machine is suitable for making complicated patterns on warp knitting fabric and is the main equipment for producing mesh decorative fabric.

In the prior art, the jacquard guide bar of the high-machine-number jacquard warp knitting machine is generally made of carbon fiber materials integrally, and the carbon fiber jacquard guide bar is formed by integral pultrusion and only has fibers transversely, so that the strength is insufficient in the longitudinal direction. When the jacquard needle block is installed, if the locking force is too large, the dovetail grooves at the upper part and the lower part of the guide bar can cause carbon fiber cracking after being stressed, so that the whole guide bar is scrapped; if the locking force is small, the jacquard needle block is not locked, and the needle beating phenomenon can occur during the operation of the warp knitting machine.

Referring to fig. 1, the existing carbon fiber jacquard guide bar is formed by pultrusion in one piece, and has fibers in the transverse direction and only resin in the longitudinal direction, so that the strength in the longitudinal direction is insufficient.

The utility model discloses a first refer to and refer to fig. 2-3, a carbon fiber merchant card sley bar, including sley bar main part 1, go up pintle 2, lower pintle 3, sley bar main part 1 is carbon fiber material, goes up pintle 2 and lower pintle 3 and is alloy material, and what use in this embodiment is aluminum alloy material, and aluminum pin axle promptly also can use magnesium alloy material. The upper pin shaft 2 is embedded into the upper part of the guide bar main body 1, the lower part of the upper pin shaft 2 is in the shape of a downward barb, and an upper dovetail groove 4 is formed at the barb; the lower pin shaft 3 is embedded into the lower part of the guide bar main body 1, the shape of the lower pin shaft 3 is an upward barb, and a lower dovetail groove 5 is formed at the barb; the guide bar main body 1, the upper dovetail groove 4 and the lower dovetail groove 5 form a C-shaped structure and can be clamped and installed with a jacquard needle block 6.

The guide bar main body 1 is formed into a strip shape extending along the horizontal direction, and a plurality of upper pin shafts 2 and lower pin shafts 3 are respectively arranged at suitable positions along the length direction of the guide bar main body, so that the upper dovetail groove 4 and the lower dovetail groove 5 can be accurately clamped with the jacquard needle block 6. The number of the upper pins 2 and the lower pins 3 is set in relation to the horizontal direction length of the bar body 1. In this embodiment, the number of the upper pin shafts 2 and the number of the lower pin shafts 3 are four, and the upper pin shafts 2 and the lower pin shafts 3 are arranged in a one-to-one correspondence manner.

The manufacturing method of the first embodiment comprises the following steps: before the carbon fiber jacquard guide bar is not processed, an aluminum pin shaft is embedded in a specific position for forming a dovetail groove, then the whole body is processed to form a structure shown in figure 2, and a dovetail groove shape is processed on the aluminum pin shaft.

When the jacquard needle block 6 is installed, an upper pin shaft 2 and a lower pin shaft 3 which are vertically corresponding are set as a pair of aluminum pin shafts, one jacquard needle block 6 is clamped on the four pairs of aluminum pin shafts, and when the locking device 7 is started, a stress point is transferred to the four pairs of aluminum pin shafts from an original dovetail groove structure. The locking device 7 of the present embodiment is a screw, and a rivet, a pin, or the like may also be used. Because the aluminum alloy intensity is better, even locking force is too big, can not lead to upper dovetail 4 and lower dovetail 5 fracture yet, fine solution jacquard needle piece locking like this is not tight, jacquard comb is scrapped easily's problem.
