The working principle of the present embodiment:

Cloth is swung through limit cloth rewinder roll 464, expanding bar 466 from rotating roller 452s, is transported to the first support roller 512, the In one transmission belt 54, third fabric guide roll 471, then it is transported to no-station pole canopy region, then from the second fabric guide roll of no-station pole canopy region 42, Two support rollers 712, the second transmission belt 74, the first expander 6 are transported to the opposite side stage, are transported to the second expander 86 again later, It is finally transported on paving cloth platform 1.And paving cloth is back and forth carried out on paving cloth platform 1 under the drive of movable motor 21.With cloth Expect that the thickness of paving is higher and higher, crane 82 can be gradually increasing under the drive of the second motor 85.

During exercise, electromagnet 34 is separated with flange 353 is pushed against, and movable motor 21 drives idler wheel 22 to rotate, to make machine Frame 2 moves on paving cloth platform 1.

When needing to stop, movable motor 21 stops operating, and electromagnet 34 is powered, and generates magnetic force, will push against flange 353 and inhales Firmly, while spring leaf is stretched that deformation occurs, pushes against flange 353 and rapidly stops operating, due to pushing against the fourth hole of flange 353 The limitation on the head of 3531 pair of second bolt 3521 so that locating flange 351 with push against that flange 353 is synchronous rapidly stops operating, Annular boss 321, the second sprocket wheel 32 is synchronous with locating flange 351 rapidly stops operating, so that the rapidly stopping of idler wheel 22 be made to turn Dynamic, rack 2 can rapidly stop.

When rack 2 will move, movable motor 21 starts, while electromagnet 34 being powered off, and pushes against flange 353 in spring leaf Elastic-restoring force under the action of back in situ, pushed against with spring leaf.Then the output shaft of movable motor 21 can drive second Sprocket wheel 32 rotates.

Under normal circumstances, any one side of cloth is between two third photoelectric sensors 56.When third photoelectric sensor 56 when detecting any one side of cloth not between two third photoelectric sensors 56, and third photoelectric sensor 56 can send electricity Signal gives the 8th motor 551 on corresponding one side, and the 8th motor 551 drives the movement of the first transmission belt 54, change is made to return two When between third photoelectric sensor 56.

Under normal circumstances, wherein one side of cloth is passed through between two the first photoelectric sensors 44.When the side is not two When between a first photoelectric sensor 44, the first photoelectric sensor 44 can be sent to 431 electric signal of third motor, make third motor 431 runnings, drive fixed frame 41 to move in rack 2, to change fixed frame 41 and spread the relative position of cloth platform 1, make this While returning between two the first photoelectric sensors 44.

Under normal circumstances, minimum point of the cloth between the first selvage guide plate 491 and the second selvage guide plate 492 is in two the 4th light Between electric transducer 49.When two the 4th photoelectric sensors 49 are all blocked or are not blocked, two the 4th photoelectric sensors 49, which can send electric signal to the 4th motor 472, adjusts the conveying speed of cloth so that the revolving speed of the 4th motor 472 changes, thus Return the minimum point of cloth between two the 4th photoelectric sensors 49.

When normal cloth conveying, the second photoelectric sensor 241 can be blocked by cloth.When the second photoelectric sensor 241 no longer When being blocked, the second photoelectric sensor 241 can send electric signal to first motor 87, the second motor 85, third motor 431, Four motors 472, the 5th motor 412, the 6th motor 451, the 7th motor 461, the 8th motor 551, the 9th motor 75, electromagnet 34 Power supply, make first motor 87, the second motor 85, third motor 431, the 4th motor 472, the 5th motor 412, the 6th motor 451, the 7th motor 461, the 8th motor 551, the power-off of the 9th motor 75, electromagnet 34, which is powered, to be braked, and is stopped working.

When two travel switches 25 detect the end disengaging of the first rack gear 433 between the two, travel switch 25 can be sent out Electric signals are to first motor 87, the second motor 85, third motor 431, the 4th motor 472, the 5th motor 412, the 6th motor 451, the 7th motor 461, the 8th motor 551, the 9th motor 75, the power supply of electromagnet 34, alarm 26, make first motor 87, Second motor 85, third motor 431, the 4th motor 472, the 5th motor 412, the 6th motor 451, the 461, the 8th electricity of the 7th motor Machine 551, the power-off of the 9th motor 75, electromagnet 34, which is powered, to be braked, and alarm 26 sounds the alarm, and equipment stops working.It is artificial to draw Dynamic cloth.

The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
