Abstract

The utility model relates to a mechanism for regulating the concavity of needle plates used for a braiding flat-knitting machine. The utility model is realized by the technical scheme that the regulating mechanism is arranged on a needle machine and comprises regulating blocks, a regulating seat and regulating screw bolts; both sides of the needle machine are provided with a plurality of chutes; the regulating seat is arranged on the needle machine, or in the chutes; one end of the regulating screw bolts is rotatablely and in circumferential direction connected with the regulating blocks through the screw holes of the regulating seat without limit; the regulating blocks are in slide connected into the chutes. The utility model has the advantages that operators can conveniently regulate from the upper part of the needle machine standing on one side of the needle machine because of the convenience of the regulation, the regulation is fine for which the regulating quantity of the concavity of the needle plates is smaller than a screw pitch and the production is quite convenient because of simple structure.

Description

Needle plate adjusting mechanism concavity

Technical field

The utility model relates to weaving machinery, more particularly, relates to a kind of Needle plate adjusting mechanism concavity on the braiding flat-bed machine.

Background technology

Needle-bar generally reaches about 2.4 meters, owing to be subjected to gravity effect, its middle part can be recessed, generally allows recessed 0.01 millimeter in needle-bar middle part.Needle plate is close to and is installed on the needle-bar, except that gravity, also will bear the power that various control triangles are bestowed on the head during work.Therefore, needle plate also can produce the concave phenomenon.When the establishment straight-bar machines was weaved cotton cloth, needle plate was flat more good more, and the needle plate concave can influence the quality of weaving cotton cloth, when concave is serious, will see obviously that the coil that knitting needle is knitted that is in dished portion is littler, want big, make same vegetables density of weaving cotton cloth inconsistent away from the coil that knitting needle is knitted of dished portion.For the quality that guarantees to weave cotton cloth all is provided with needle plate concave governor motion on needle-bar.In the prior art, the structure setting of this governor motion as shown in Figure 1,5～8 screws and concentric counterbore respectively are set in the both sides of needle-bar 4, place in counterbore and regulate copper post 1, tightening double-screw bolt 2 is rotatably connected in screw, rotation tightening double-screw bolt 2, its spiral that makes progress is moved, it will push against to regulate on the copper post 1 and move, and produce a pushing force that makes progress and will make needle plate 3 that the elasticity of flexure distortion that makes progress take place until being tight against needle plate 3, to offset the recessed phenomenon of needle-bar.But this adjusting needs operating personnel to pierce the needle-bar bottom to be carried out, very inconvenient.

Summary of the invention

The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, designs a kind ofly just can make things convenient for a kind of Needle plate adjusting mechanism concavity of regulating to needle plate concavity at the needle-bar upside, and it is realized by following technical scheme:

Described governor motion, be installed on the needle-bar, it comprises regulating block, adjustment seat and adjusting screw(rod), and some chutes are set in described needle-bar both sides, adjustment seat is installed on the needle-bar or in the chute, one end of adjusting screw(rod) spins and passes screw and regulating block on the adjustment seat and circumferentially do not have constraint and be connected, and regulating block slips in chute.

Described regulating block is the baseplane becomes the α angle with the top Plane intersects 6 bodies of wedge, α＜45 °.

Described chute bottom surface and needle-bar face intersect the α angle.

Described adjusting screw(rod) one end is plugged in the connecting hole on the regulating block, all sides of described adjusting screw(rod) end are provided with the cotter way of annular sealing, two connecting pins laterally penetrate this connecting hole along two symmetrical string of a musical instrument directions of described connecting hole, and its middle part is plugged in the described cotter way.

The beneficial effects of the utility model are: 1) adjusting is very convenient, and operating personnel stand on needle-bar one side and just can regulate from the needle-bar upside easily; 2) adjusting is trickle, and needle plate concavity regulating quantity can be much smaller than a pitch; 3) simple in structure, process also very convenient.

1 is to regulate copper post, the 2nd, tightening double-screw bolt, the 3rd, needle plate, the 4th, needle-bar, the 5th, regulating block, the 6th, adjusting screw(rod) among the figure, the 7th, adjustment seat, the 8th, bolt, the 9th, cotter way, the 10th, connecting pin, the 11st, chute, the 12nd, needle-bar face, the 13rd, chute bottom surface, the 14th, baseplane, the 15th, plane, top, the 16th, connecting hole.

The specific embodiment

Below in conjunction with drawings and Examples the utility model and advantage thereof are described further.

Contrast Fig. 2, Fig. 3 evenly are provided with 5 chutes respectively at the middle part of needle-bar 4 symmetrical both sides, settle a Needle plate adjusting mechanism concavity (for the clear chute structure of expressing, taking down the governor motion in symmetrical right side among Fig. 2, Fig. 3 left side) on each chute 11.The adjustment seat 7 of present embodiment is installed in chute 11 1 ends by bolt 8, one end of adjusting screw(rod) 6 spins and the screw that passes on the adjustment seat 7 is connected with regulating block 5, its syndeton sees also Fig. 4: an end of adjusting screw(rod) 6 is plugged in the connecting hole 16 that is a bit larger tham the screw rod end diameter on the regulating block, all sides in the adjusting screw(rod) end are provided with the cotter way 9 of annular sealing, two connecting pins laterally penetrate this connecting hole 16 respectively along two symmetrical string of a musical instrument directions of connecting hole 16, and its middle part is plugged in the cotter way 9.This syndeton is axially located and circumferentially nothing constraint adjusting screw(rod) 6 in regulating block 5.Referring again to Fig. 2, in conjunction with Fig. 4, regulating block 5 is bearing in the other end of chute 11, can slide along chute 11.The bottom surface of chute 11 and needle-bar face intersect the α angle, the baseplane of regulating block 5 is close to the groove bottom 13 of chute 11, it also becomes the α angle with plane 15, top, so 6 bodies of wedge that regulating block 5 is a pair of corresponding surfaces to be not parallel to each other, the plane, top 15 of regulating block 5 is parallel with needle-bar face 12.

When needs were regulated needle plate concavity, operating personnel moved its spiral that makes progress in the hexagonal end of needle-bar upside with spanner turn adjusting screw(rod) 6, and adjusting screw(rod) 6 promotes regulating block 5 and upwards slides along chute 11.Because regulating block 5 is the wedge shape, regulating block 5 is when front slide, and the contact position of it and needle plate 3 is constantly by bed hedgehopping, and its pushing and pressing effect makes the contact position produce bending stress to make needle plate 3 produce elastic bending deflections, to offset the concave phenomenon of needle plate 3.Because the plane, top 15 of regulating block 5 is parallel with needle-bar face 12, so when pushing up plane 15 when exceeding chute 11 and promptly being higher than needle-bar face 12, the angle of the bearing-surface of needle plate 3 is constant.Simultaneously because the plane, top 15 of regulating block 5 and needle-bar face 12 angle α are one much smaller than 45 ° angle, present embodiment α=5 °, regulating block 5 is along the groove bottom pitch of upwards sliding, tg α pitch doubly only rises on the Qi Ding plane, and tg α＜＜1, so the utility model has the fine setting effect when carrying out the concavity adjusting.
