Nonwoven fabric felt unrolling frame

Abstract

The invention provides a nonwoven fabric felt unrolling frame which can keep constant tensioning force with a nonwoven fabric knitting unit during unrolling of nonwoven fabrics. The nonwoven fabric felt unrolling frame comprises two wall plates of the felt unrolling frame, and a tensioning rod, a felt guide roller and two pneumatic tensioning shaft are connected between the two wall plates. A main shaft head is arranged at one end of the pneumatic tensioning shaft while an auxiliary shaft head is arranged at the other end of the pneumatic tensioning shaft, and a safety flange is mounted on the inner side of each of the main shaft head and the auxiliary shaft head and on the pneumatic tensioning shaft. Bearing blocks are mounted on the inner wall of the two wall plates of the felt unrolling frame corresponding to the left end and the right end of the pneumatic tensioning shaft, the main and auxiliary shaft heads of the pneumatic tensioning shaft are mounted in bearings of the bearing blocks, a fixed plate is mounted outside the auxiliary shaft head, and the main shaft head penetrates through the bearing blocks to extend outside the wall plates. A retaining belt pulley spacer ring is sleeved on a portion, close to the end, of the main shaft head. A brake wheel is mounted at the end of the main shaft head through bolts, and a supporting column horizontally extends outwards on the wall plate at the mounting end of the brake wheel and is positioned below the brake wheel. A brake belt is sleeved on the brake wheel, a connecting plate is fixed to the end of the brake belt, a hook is fixed to the bottom end of the connecting plate through a hook screw, a hanging plate is hung at the bottom of the hook, and a counter weight is placed on the hanging plate.

Description

technical field [0001] The invention relates to non-woven fabric spinning equipment, which is specifically applied to the unwinding of non-woven fabrics. Background technique [0002] When the textile machine is weaving, the cloth surface needs to maintain tension to achieve high-quality textile. The existing tensioning device is either a simple tensioning pulley of the transmission belt, or a separate felt rack with non-adjustable tension. The simple transmission belt tension The tight wheel structure cannot meet the tension requirements of wide-format textiles. The tension cannot be adjusted by a separate felt frame, which cannot meet the long-term textile needs, because the tension of the cloth surface will change for a long time. When the changes accumulate more and more It cannot meet the textile requirements; the above-mentioned tensioning methods will eventually affect the textile quality, and they cannot provide the non-woven fabric surface tension required by the pe...
