As shown in fig. 1 and 2, the utility model relates to a double-station passive unwinding device, which comprises a base 8, wherein a rack 1 is movably arranged on the base 8, and the rack 1 is driven by a centering assembly 6 arranged on the side of the base 8.
The top of the frame 1 is provided with a first station 2 and a second station 3, the first station 2 and the second station 3 are respectively provided with a discharging roller in a rotating way, and the axial end part of the discharging roller is provided with a magnetic field clutch 4. The magnetic field clutch 4 is a mature product in the prior art and acts like a brake disc. When the machine works, the fabrics to be unreeled on the two stations are unreeled under the action of constant tension, and during initial unreeling operation, the unreeling operation is relatively stable due to the fact that the diameter ratio of the fabric material roll is larger; after the material is unreeled for a period of time, the diameter of the material roll is reduced; at this moment, the magnetic powder clutch 4 is required to adjust resistance so as to reduce the rotating speed of the discharging roller and ensure stable discharging.
A guide roller 7 is rotatably arranged below the second station 3, the guide roller 7 guides the discharged fabric, a tension roller assembly 5 is arranged beside the base 8, and the tension roller assembly 5 is matched with an external force measuring component, so that the tension state of the discharged fabric can be detected, and the reliable and stable unwinding of the fabric is ensured.
In specific operation, the frame 1 is moved as follows: a guide rail is arranged on the base 8, rollers arranged on the bottom surface of the rack 1 are supported on the guide rail, and the centering component 6 drives the rack 1 to move on the guide rail.
The centering assembly 6 comprises a centering cylinder 6-1 and a centering connecting seat 6-2, the centering cylinder 6-1 is installed on the base 8, the centering connecting seat 6-2 is installed on the rack 1, and a piston rod of the centering cylinder 6-1 is connected with the centering connecting seat 6-2.
When unreeling, centering subassembly 6 drives frame 1 and adjusts the removal on base 8 according to concrete behavior to ensure that at the during operation, drive frame 1 and adjust to suitable position, realize going on smoothly unreeling.
The tension roller assembly 5 comprises a tension detection supporting seat 5-1, two ends of the tension detection supporting seat 5-1 in the length direction are respectively provided with a material guiding part 5-2, the distance between the two material guiding parts 5-2 is adjustable, and a tension detection supporting roller 5-3 is further rotatably arranged on the tension detection supporting seat 5-1.
The material guiding component 5-2 comprises a rectangular sliding sleeve 5-21 and a material guiding block 5-22, and the material guiding block 5-22 is fixedly connected with the rectangular sliding sleeve 5-21 through a connecting bracket 5-23; the rectangular sliding sleeve 5-21 is sleeved on a rectangular rod arranged on the side portion of the tension detection supporting seat 5-1, the rectangular sliding sleeve 5-21 is positioned with the rectangular rod through a positioning bolt, and the guide block 5-22 is provided with a guide chute. The rectangular sliding sleeve 5-21 can slide on the rectangular rod to ensure that the guide blocks 5-22 can always realize reliable limiting and guiding on the unreeled fabric.
The rack 1 comprises two side plates 1-1 which are arranged in parallel, the upper parts of the two side plates 1-1 are in supporting connection through upper supporting columns 1-2, and the lower parts of the two side plates 1-1 are in supporting connection through lower supporting columns 1-3.
The bottom of the frame 1 is provided with a connecting bolt 9 so as to realize reliable installation and fixation of the product of the utility model when in use.
As shown in fig. 1 and 2, when the product of the utility model works, materials to be uncoiled are respectively rotatably arranged on a first station 2 and a second station 3, when the product works, the materials to be uncoiled on the first station 2 are uncoiled firstly, the materials to be uncoiled on the first station 2 are drawn out, then are led out through a guide roller 7, then pass through a guide chute of a guide frame 5-2, then are led out to a tension detection roller 5-3, and are uncoiled for standby after passing through the tension detection roller 5-3.
Because the outer end of the coil stock is pulled by constant tension to be unreeled outwards during unreeling operation, the diameter of the coil stock is larger at the beginning, the corresponding coil stock shaft rotates more stably during unreeling, and the whole diameter of the coil stock is reduced after unreeling for a period of time, at the moment, in order to avoid the constant tension action, the rotating speed of the coil stock shaft is too high, a certain resistance is applied to the coil stock shaft through the magnetic field clutch 4, so that the rotating speed of the coil stock shaft is correspondingly reduced, and stable and reliable unreeling operation can be realized.
