Abstract

The utility model discloses a ramie textile stretch breaking machine which is composed of a machine frame and three sets of stretch breaking devices, wherein each stretch breaking device is composed of a motor, a bearing seat, a pressurizing leather roller, a fluted roller and an oil hydraulic cylinder. The bearing seat of the ramie stretch breaking machine is a diplopore bearing seat. The supporting positions of the diplopore bearing seat are displaced backwards and forwards. The bearing seats of the three sets of stretch breaking devices are installed in displacement. The tooth shape of the fluted roller is in a complete circular arc surface, and the pressurizing leather roller is in a single arm structure. A locating shaft of the pressurizing leather roller is hidden in the central position of the pressurizing leather roller. The pressurizing leather roller is positioned on the two fluted rollers, which forms a structure in the shape like the Chinese character 'pin'. Gathering two procedures of opening picking and beating, the novel ramie textile stretch breaking machine of the utility model has the advantages of high pressure, high traction proportion, no winding, no neps, low over-length fiber rate, good quality, simple equipment and small ground occupying.

Description

The ramie textile stretch breaking machine

Technical field:

The utility model belongs to the ramie textile process equipment, is specifically related to a kind of ramie stretch breaking machine,

Background technology:

At present in the ramie processing technology, the process equipment of " shredding " and " comb fiber crops " two procedures adopts " opener " and " steel wire machine " respectively, in process, ramee is produced serious strike and tears, make the skewer dimension that wrapping phenomena take place at the volley, thereby cause the generation of skewer dimension fiber crops grain and the decline of short fiber index, seriously influenced the quality of resultant yarn and lining, also reduced the row yielding of raw material simultaneously.

Summary of the invention:

In order to overcome the deficiency of " shredding " and " comb fiber crops " two procedures process equipment technology in the existing ramie textile processing, the utility model provides a kind of collection " shredding " and " comb fiber crops " two procedures be the big pressure of having of one, high draft than, do not twine, do not have numb, the ramie textile stretch breaking machine of the overcut fibre rate is low, quality good, equipment is simple, floor space is little brand new.The operation principle of this stretch breaking machine is the adjustment of spacing by to pressure, draw ratio and drawing-off, makes between bundle fiber to produce relative slippage and become the filament state, finally leads disconnected by technological requirement.

The technical scheme in the invention for solving the technical problem is: the utility model is made of frame and three groups of stretch-breaking devices, each group stretch-breaking device constitutes by motor, bearing block, pressurization roller, fluted roll and oil hydraulic cylinder, motor, bearing block and oil hydraulic cylinder place on the frame, described motor is a frequency control motor, and motor is connected with the fluted roll power shaft by shaft joint; Described fluted roll one end links to each other with the power axle bed, and the other end links to each other with unpowered axle bed, and the profile of tooth of fluted roll is the wholecircle cambered surface, and the contact pressure angle is 20 degree, and the intersection rib is R0.5; Described pressurization roller is the built-in pressurization roller of single armed, ensconce the center of pressurization roller in its locating shaft, the pressurization roller places on two fluted rolls, form the gripping state of one group of isosceles triangle with two fluted rolls, pressurization roller arm end, connecting rod, the flexible connection of connecting with oil hydraulic cylinder, pole one end and frame are fixedly linked, and the other end and armed lever fulcrum are movably connected; Described bearing block is the diplopore bearing block, dislocation before and after its Support Position, arranged in dislocation before and after three groups of stretch-breaking device bearing blocks.

The beneficial effects of the utility model are: the one, because diplopore bearing block Support Position front and back misconstruction and three groups of bearing block arranged in dislocation, satisfied bearing block, requirement that the rigid design of fluted roll requires and the minimum of process stipulation is spaced, three groups of built-in pressurization rollers of single armed and three pairs of fluted rolls form product word structure, make fiber between roller and fluted roll, produce specified grasping force, thereby realize drawing-off and crush cutting effect to fiber, guaranteed the minimizing of quality of fiber and overcut fibre rate, its overcut fibre rate is controlled at the inhomogeneous rate of 3% following fibre length and lacks about 20% than the carded ramie stripes; The 2nd, the structure of the built-in centralized positioning axle of the built-in pressurization roller of single armed axially is not subjected to the influence of charging gage distortion, makes fluted roll upwards docile all the time with roller at X and Y, guarantees enough grasping forces; The 3rd, fluted roll " wholecircle cambered surface " tooth-shape structure reduces fiber at the volley and hangs the thorn phenomenon, avoid twining, and reduces " fiber crops grain " and produces; Four is mounting structures of three groups of direct-connected roller power shafts of motor, and floor space is little; The 5th, to compare with " shredding ", " comb fiber crops " machine, stretch breaking machine is simple in structure, the efficient height.

The specific embodiment:

Below in conjunction with the drawings and specific embodiments the utility model is further described:

As shown in Figure 1, 2, 3, the utility model is made of frame 4 and three groups of stretch-breaking

devices

1,2,3; As shown in Figure 4, each group stretch-breaking device constitutes by motor 5,

bearing block
