Abstract

The utility model relates to an active spreader, composed of a drive roller, a driven roller, a motor, a central shaft, a worm wheel, etc. The utility model is characterized in that the both sides of the central shaft are respectively provided with the drive roller and the driven roller, and one end of the central shaft is provided with the worm wheel. The bearings of the central shaft, th edrive roller and the driven roller are parallel, and one side of the worm wheel of one end of the central shaft is provided with a worm screw which is matched with the worm wheel. The utility model overcomes the disadvantage that the passive spread effect of other spreaders is poor, and is wide suitable for the printing and dyeing industry to spread piece goods.

Description

Active spreader

The utility model relates to field of printing and dyeing, a kind of specifically special-purpose machinery that is used for the cloth expanding after the printing and dyeing.

The social at present expander that generally uses all is the passive expandings of single roller, rotates by cloth pulling spreading roll, and tension is little, reaches desirable expanding effect.

The purpose of this utility model is, designs a kind of outer power and drives, and two rollers are simultaneously to the two-sided equipment that carries out expanding of cloth.

The technical solution of the utility model is, a kind of Active spreader is to be made of drive roll, driven roll, motor, central shaft, worm gear etc., and its special character is, adorns a drive roll and a driven roll respectively in the both sides of a central shaft, and an end of central shaft is equipped with worm gear.Central shaft, drive roll, driven roll three's bearing parallels.One side of central shaft one end worm gear is equipped with the worm screw that is mated.There is rotating handwheel the worm screw outer end, and the two is integral.The two ends of drive roll, driven roll and the two ends of central shaft are connected into integrated.During expanding cloth put and drive roll and driven roll between, start the driven by motor driving wheel and rotate.Driving wheel drives follower again rotates drive roll, driven roll simultaneously in opposite directions, cloth is carried out expanding, tension between cloth and drive roll, driven roll is excessive or too hour, can pull the handwheel of central shaft one end, by worm screw, worm gear rotary middle spindle, drive roll, driven roll are rotated to adjust tension size between cloth and two rollers around central shaft.

Owing to take technique scheme, can realize the very good special-purpose machinery of a kind of expanding effect.

Embodiment further specifies below in conjunction with accompanying drawing.

Fig. 1 is a structural front view of the present utility model, and the accompanying drawing that makes an abstract.

Among the figure, 1 worm gear, 2 worm screws, 3 handwheels, 4 central shafts, 5 drive rolls, 6 driven rolls, 7 driving wheels, 8 motors, 9 followers

As shown in the figure, adorn a drive roll 5 and a driven roll 6 respectively in the both sides of a central shaft 4, an end of central shaft 4 is equipped with worm gear 1.Central shaft 4, drive roll 5, driven roll 6 threes' axis parallels.One of central shaft 4 one end worm gears 1 are surveyed the worm screw 2 that is mated are housed.There is rotating handwheel 3 worm screw 2 outer ends, and the two is integral shape.The two ends of the two ends of drive roll 5, driven roll 6 and central shaft 4 are connected into integrated.During expanding cloth put and drive roll 5 and driven roll 6 between, start motor 8 and drive driving wheels 7 and rotate.Driving wheel 7 drives follower 9 again rotates drive roll 5, driven roll 6 simultaneously in opposite directions, cloth is carried out expanding, tension between cloth and drive roll 5, driven roll 6 is excessive or too hour, can pull the handwheel 3 of central shaft 4 one ends, by worm screw 2, worm gear 1 rotary middle spindle 4, drive roll 5, driven roll 6 are rotated to adjust tension size between cloth and two rollers around central shaft 4.

Claims

1, a kind of Active spreader is to be made of drive roll, driven roll, motor, central shaft, worm gear etc., and it is characterized in that: an end of adorning a drive roll and a driven roll, central shaft in the both sides of a central shaft respectively is equipped with worm gear.

2, Active spreader according to claim 1 is characterized in that: central shaft, drive roll, driven roll three's bearing parallels.

3, the spoke device that initiatively expands according to claim 1 is characterized in that: a side of central shaft one end worm gear is equipped with the worm screw that is mated.
