Description

A kind of cloth expanding device

Technical field

The utility model relates to the garment devices field of mechanical technique, the concrete cloth expanding device that relates to a kind of granny rag machine.

Background technology

The granny rag machine can be tiled in the cloth of rolling on the board, the mode of its tiling is the movable casing by sliding in the board upper end, utilize its moving back and forth on board that cloth is changeed continuously back and forth Zhe and folded gradually high, utilize other facility that the cloth cutting of multilayer tiling is become clothing with style again.

General traditional granny rag machine does not have special project organization, because some cloth is soft material, knitted cloth particularly, has retractility, cloth can slightly stretch at direct of travel when drawing, but then slightly shrink in both sides relatively, treat that drawing is to certain-length, the elastic-restoring force of its dress material often causes many wrinkle Zhe, and the length of its tiling is all inequality because of drawing state when the drawing or not following time, makes being layered on that the granny rag cloth can not be smooth cut out on the bed, need manually to be put in order, strengthened working strength of workers, operating efficiency reduces greatly, brings difficulty also for simultaneously the operation that step such as cuts backward.

The Chinese patent Granted publication, CN2233410Y, name is called the spread device patent of granny rag machine, be characterized in, the utility model relates to a kind of spread device of granny rag machine, be characterized in comprising the column block set in a tape spool hole, the one oblique wheel seat that is provided with the bar shape of central perforation is set on this block set, form oblique groove at its periphery, axis hole is passed in the end of pull bar, and its other end that stretches out is fixed, and ring is established a plurality of fixedly ring stands on the pull bar: a plurality of spread slide plates that are provided with vertical slotted hole, pass slotted hole by screw it is located on pull bar week side, be provided with anti-slide plate on the spread slide plate, a pulley is located in the groove, adopts said structure, deflection in the time of can making the vertical drawing of its elastic woven material is unlikely excessive, thereby makes the cloth of being pulled out just comparatively smooth.The spread problem when though this scheme has effectively solved the operation of granny rag machine, this cloth expanding device is very simple and crude, and the amplitude of spread is difficult to regulate, and is difficult to satisfy the spread demand of different clothes.And the mechanism that regulates the spread amplitude is the linkage operation, and in the complete machine running, connecting rod can produce loosening.

The utility model content

Technical problem to be solved in the utility model is, overcomes problems of the prior art, and a kind of cloth expanding device is provided.

In order to address the above problem the technical solution of the utility model is such:

A kind of spreading roller for spreader comprises a rotating running roller, and described running roller is arranged on the roller frame, and running roller one end has power input shaft, and running roller is provided with horizontally slip and the symmetrical plurality of vanes that is used for spread; Described running roller two ends are provided with the sheave that driven vane horizontally slips, it is characterized in that, described running roller is provided with slide rail, described blade is connected on the slide rail, blade tip has the sheave contact, the blade appearance is provided with the blade skin, by the detachable also adjustable sheave that is connected with of a clamping screw, has an annular skewed slot on the described sheave on the roller frame of both sides; What the sheave contact of described blade tip slided is embedded in the described annular skewed slot.

Described annular skewed slot, half is vertical anchor ring groove, half is oblique anchor ring groove.

Have the arcuate socket of a scope of move left and right when being used to change the sheave position and then changing the blade spread within the specific limits on the described roller frame, described clamping screw is locked sheave in the arcuate socket scope.

Described sheave has an annular wall, has one on the described annular wall and is used for described sheave is fixed on the steady pin that in the rotating shaft of described running roller described sheave is rotated with running roller, and this steady pin makes blade not carry out the spread action when tightening.

Described blade skin is the bigger diving cloth of relative cloth cover frictional force, and diving cloth is styrene-butadiene rubber.

When carrying out spread work, running roller rotates, and the sheave at two ends does not rotate, and the troughed belt moving vane on the sheave horizontally slips, and carries out spread work; When needs are adjusted the spread amplitude, adjust the sheave locked position, in the time of can changing the running roller motion, blade spread amplitude; When not needing the spread function, the cancellation clamping screw is fixed on sheave in the rotating shaft with steady pin, makes sheave rotate together in running roller, and blade just can not horizontally slip like this, has not possessed the spread function.

Beneficial effect, this people's delicate structure, slide flexibly, and can regulate different spread amplitudes, perhaps cancel the spread function according to different needs, only carry out the granny rag function, the method of operation is various, and when carrying out spread work, distinctive spread blade skin makes cloth and running roller have frictional force preferably, spread is respond well, increases work efficiency greatly.
