Abstract

The utility model relates to a bottom-initiating device of a flat knitting machine. The bottom-initiating device comprises a bottom-initiating needle board, initiating needles and a driving device. Needle grooves are evenly arranged in the needle board and are arranged along the length direction of the needle board, the initiating needles are arranged in the needle grooves, and the initiating needles are parallel with the bottom-initiating needle board and driven by the driving device to move. The bottom-initiating device of the flat knitting machine has the advantages that the short edge of the section of each initiating needle is smaller than a gap of a needle bed port due to special design of the needle grooves, namely, the thickness of each initiating needle is smaller than the gap of the needle bed port, therefore mutual interference in the process of moving is avoided, and working stability is high.

Description

The bottom rising device of flat machine

Technical field

The utility model relates to a kind of bottom rising device of flat machine, belongs to the flat machine technical field.

Background technology

Flat machine can be finished the braiding of a complete garment piece, generally speaking, complete garment piece mainly by refuse yarn, take out stitches, rise the end, idle running, rib-loop, bodice etc. and partly form; Because of the roller output procedure of knitted fabric after circle is moved back in lopping, be that knitted fabric with moulding pulls out from knitting point, send after giving the fabric certain force of strain, tractive is very big to knitting cycle and product quality influence, thereby should possess following basic demand: at first, because knitting cycle carries out continuously, so the tractive motion also will continuously move; The tractive tension force that acts on each coil wants even, stable, consistent; Tractive tension force in unit interval and tractive amount and lopping technology will be carried out synchronously.But because there being certain distance in the flat machine between needle-bar mouth and the pulling device, when the sheet clothing weaves, can not just be pulled the device clamping at once, this moment is if directly weave, then Bian Zhi sheet clothing (i.e. the sheet clothing of not lived by the roller clamping) will Yin Lali inhomogeneous and out-of-flatness, therefore influenced the integral weaving effect of garment piece; In addition, when garment pieces such as machine need continuous weaving V neck or crew neck, because the initial fabric width difference of garment piece, refuse yarn need be woven again and just the braiding of next garment piece can be carried out, therefore, must realize the integral weaving of garment piece before taking up one's knitting by means of refuse yarn, so not only reduce whole operating efficiency, also waste the use of yarn greatly.

In order to address this problem, people realize that with a kind of needle for setting up fabrics and corresponding bottom rising device the closely tractive of fabric has reached end effect, a kind of needle for setting up fabrics is disclosed as Chinese patent CN1023906, in the technical scheme and other prior art of this application, needle for setting up fabrics all is vertically to arrange, namely perpendicular to playing base plate.

Because bottom rising device is when work, needle for setting up fabrics need rise to needle-bar mouth place and hang yarn, and the gap of needle-bar mouth is less, and the gap of different type of machines needle-bar mouth is also inconsistent, moves interference easily, has influenced end action.

Summary of the invention

The purpose of this utility model provides the bottom rising device of the higher flat machine of a kind of stability.

The technical scheme of taking for realization the utility model purpose is as follows:

The bottom rising device of flat machine comprises needle plate, needle for setting up fabrics and drive unit, evenly is provided with needle tray on the needle plate, and needle for setting up fabrics is installed in the needle tray, and described needle tray is along the length direction setting of needle plate.

Further:

Described needle for setting up fabrics is parallel to needle plate.

Operation principle of the present utility model and beneficial effect are as follows: the structure of needle for setting up fabrics, all be to be combined by longilineal groove pin and longilineal crochet hook, the cross section is rectangle, adopt the bottom rising device of the utility model flat machine, because needle tray is the length direction setting along needle plate, when needle for setting up fabrics was put into needle tray, needle for setting up fabrics vertically was arranged on the needle plate, long limit, its cross section has been parallel to end needle plate, and needle for setting up fabrics cross section minor face is perpendicular to playing end needle plate.When needle for setting up fabrics rising and extension yarn, by the control of system, can adjust the left and right sidesing shifting of needle-bar, can not upset yarn, thereby yarn is farthest contacted fully with the crochet hook of needle for setting up fabrics, make needle for setting up fabrics better tangle yarn, the job stability of bottom rising device is higher.

Fig. 2 is the structural representation of the needle for setting up fabrics that relates in the utility model;

Fig. 3 is the cutaway view Amplified image in the A-A cross section of the needle for setting up fabrics that relates in the utility model.

Number in the figure: 1, needle plate; 11, needle tray; 2, needle for setting up fabrics; 21, groove pin; 22, crochet hook; 23, long limit, cross section; 24, cross section minor face; 3, drive unit.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, the bottom rising device of the utility model flat machine, the bottom rising device of flat machine comprises needle plate 1, needle for setting up fabrics 2 and drive unit 3, evenly is provided with needle tray 11 on the needle plate 1, needle tray 11 is along the length direction setting of needle plate 1; Needle for setting up fabrics 2 comprises groove pin 21 and crochet hook 22, and needle for setting up fabrics 2 is installed in the needle tray 11, and is parallel to needle plate 1, so, long limit 23, the cross section of needle for setting up fabrics 2 is parallel to needle plate 1, and the cross section minor face 24 of needle for setting up fabrics 2 is perpendicular to needle plate 1, play end pin 2 and be installed in the needle tray 11, drive motion by drive unit 3.

The structure of the bottom rising device of the utility model flat machine has been avoided the movement interference in the machine operation process, the convenient yarn of hanging, and performance is more stable.

Claims

1. the bottom rising device of flat machine comprises needle plate, needle for setting up fabrics and drive unit, evenly is provided with needle tray on the needle plate, and needle for setting up fabrics is installed in the needle tray, it is characterized in that: described needle tray is along the length direction setting of needle plate, and needle for setting up fabrics is parallel to needle plate; Wherein, needle for setting up fabrics comprises groove pin and crochet hook, and long limit, the cross section of needle for setting up fabrics is parallel to needle plate, and the cross section minor face of needle for setting up fabrics is perpendicular to needle plate.
