Description

Large needle number high-velocity electrons jacquard

Technical field

The utility model relates to a kind of high-velocity electrons jacquard, especially belongs to a kind of large needle number high-velocity electrons jacquard.

Background technology

CN203795063U discloses a kind of " having the high-velocity electrons jacquard of four-wheel-type shedding mechanism " by the applicant's previous application, its structure is by two blocks of wallboards, a main shaft, and girff, griffe clamping plate and the parts such as to griffe and form, the axle body of main shaft is provided with four eccentric wheels, these eccentric wheels all have an outer ring, and the V shape lower contact of one, outer ring and girff are connected, in addition, be provided with tip chute and linkage in the side of two blocks of wallboards, they are for the formation of clear shed open.During operation, main shaft rotates under loom dynamical system drives, and outer ring rotates with eccentric wheel, drives V shape lower contact to pump in guide chute, control girff, griffes clamping plate and griffe to pull heald, makes loom warp form clear shed open.These facility have advantage that is rational in infrastructure, that operate steadily, but due to the impact by the factors such as girff width, running speed, it is excessive that its main shaft and eccentric wheel exist load, and assembled machine balance is poor, vibrate the problems such as large.And uncomfortable cooperation large needle number high speed jacquard machine uses.

Summary of the invention

For solving the problems referred to above that prior art exists, the utility model aims to provide a kind of large needle number high-velocity electrons jacquard, these facility have rational in infrastructure, operate steadily, vibrate little and that noise is low advantage.

For achieving the above object, the utility model have employed following technical proposals:

This large needle number high-velocity electrons jacquard, comprise two blocks of wallboards, a main shaft and four girffs, axle body along this main shaft is provided with four eccentric wheels successively, these eccentric wheels are hinged through outer ring and the V shape lower contact of stretching downwards thereof and described four girffs respectively, it is characterized in that: the axle body of described main shaft is provided with a travelling gear; Two blocks of described wallboards are provided with a driven shaft paralleled with described main shaft, and this driven shaft to engage with described travelling gear through driven gear and links; Match with described main shaft, the axle body along this driven shaft is also provided with four eccentric wheels, and these eccentric wheels are also hinged through the opposite side of respective outer ring and the V shape lower contact of stretching downwards and described four girffs respectively; Eccentric wheel on described driven shaft and main shaft has the not consistent degree of eccentricity.

As preferably, described V shape lower contact is positioned in one in the guide chute of downward-extension.

As preferably, when specifically implementing, one block of Side fascia respectively can be set up, to improve intensity at two axle heads of described main shaft and driven shaft.

Beneficial effect: compared with prior art, the utility model is after original main shaft side increases a set of traction newly and drives the mechanism of girff action, because all loads are shared by main shaft and driven shaft, and every sheet girff all has two eccentric wheels through outer ring and V shape lower contact traction thereof, therefore complete machine have balance good, operate steadily reliable, vibrate the advantage that little noise is low.

For deepening understanding of the present utility model, be described in further detail by embodiment below in conjunction with accompanying drawing.

Accompanying drawing explanation

Fig. 1 be in the utility model complete machine one piece of wallboard side face structural representation.In figure, two V shape lower contacts are positioned at bottom dead center position.

In figure: wallboard 1, travelling gear 2, driven gear 3, main shaft 4, driven shaft 5, eccentric wheel 6, outer ring 61, V shape lower contact 62, girff 7, griffes clamping plate 71, griffes 72.

Detailed description of the invention

See Fig. 1.This large needle number high-velocity electrons jacquard, with regard to complete machine, has vertically to the parallel two blocks of wallboards 1 stood in frame, and be shelved on these two blocks of wallboards, the main shaft 4 that is parallel to each other and a driven shaft 5.If observed from the front of wallboard 1, on the axle body of wallboard, travelling gear 2 is fixed with and driven gear 3(only has this two parts in this face) at main shaft 4 and driven shaft 5, and be respectively equipped with eccentric wheel 6 and outer ring 61 thereof, outer ring 61 is arranged on the periphery of eccentric wheel 6 through bearing, outer ring 61 extends V shape lower contact 62 downwards, and lower end and the girff 7 of V shape lower contact 62 are connected.Because the every sheet girff 7 of this machine all has two V shape lower contacts 62 to connect, be therefore applicable to the application of large needle SerComm width girff, balance is good.

For forming clear shed open, the eccentric wheel on main shaft 4 and driven shaft 5 should have the not consistent degree of eccentricity, and the degree of eccentricity determines shed open size.That is: when two V shape lower contacts 62 all go to lower dead center, girff 7 has gradient, and is in level when top dead centre.

For improving the stability that girff 7 moves up and down, V shape lower contact 62 can be placed in one in the guide chute of downward-extension through slide block.Moreover, when specifically implementing, can respectively set up one block of Side fascia again, to improve intensity at two axle heads of described main shaft 4 and driven shaft 5.

During operation, main shaft 1 rotates under motor and transmission mechanism drive, and engage driven gear 3 through travelling gear 2 and rotate together, then, main shaft 4 and driven shaft 5 make eccentric wheel 6, outer ring 61 and V shape lower contact 62 action thereof successively, realize girff 7 to pump, make girff 7 through griffe clamping plate 71, griffe 72 to pull heald and control loom warp and form clear shed open.
