The device comprises an unreeling rack, a winding roller, a cloth pressing roller, an electret tank, an electret cylinder, a pressing cloth guide roller, a cloth guide roller, a swing rack, an adjustable cloth cutting knife rest, a cloth cutter, a cloth cutter shaft, a cloth pressing roller, a cloth support roller, a cloth inspection light source, a rolling tension controller, a main transmission motor, a counterweight component, a cutter shaft motor, a stander braking controller, a quick clamping device and an air expanding shaft, wherein two ends of the winding roller are arranged on the unreeling rack, the outside of the electret cylinder is provided with the electret tank which is provided with a plurality of rows of high-pressure discharge brushes, and a stander is grounded; the cloth pressing roller and the pressing cloth guide roller are arranged on the standers at two sides of the electret cylinder respectively, the swing rack is movably arranged at two sides of the stander, the lower part of the swing rack is provided with the counterweight component, and the cloth guide roller, the cloth support roller and the cloth pressing roller are arranged at the upper part of the swing rack in turn; and the air expanding shaft is arranged on the stander at the lower part of the swing rack through a bearing block, and the swing rack at one end of the cloth pressing roller is provided with the main transmission motor.

Description

technical field [0001] The invention relates to a non-woven fabric electret and slitting machine, which relates to a kind of non-woven fabric electret and slitting equipment, which is suitable for spun-bonded fabrics, needle-punched fabrics, and spray-on fabrics made of high molecular polymers. Melt cloth, especially the electret, slitting, compounding and multi-purpose machine for melt blown filter cloth. Background technique [0002] At present, melt-blown nonwovens are mainly used for filter materials, and paper slitting machines are mostly used for cutting semi-finished products. The slitting method is: use the upper and lower round knives to rely on the rotating torque during winding to drive the rotation of the upper and lower round knives to cut the material to be cut. With this method, the equipment needs a large pulling force to drag the cloth roll when slitting the melt-blown non-woven filter cloth, while unwinding and rewinding, and at the same time drive the upp...

AI Technical Summary

Problems solved by technology

With this method, the equipment needs a large pulling force to drag the cloth roll when slitting the melt-blown non-woven filter cloth, while unwinding and rewinding, and at the same time drive the upper and lower slitting circular knives to rotate at the same speed as the cloth , such a slitting method makes the slitting products roll very tightly, and the slitting speed also increases with the increase of the winding diameter, which is extremely unfavorable to the slitting of the melt-blown filter material, and will increase the filtration rate. The resistance of the material, the filtration efficiency and resistance of the filter material are the main quality indicators of the filter material. Too tight coiling will double the resistance of the filter material, especially for the fluffy filter material.

At the same time, it is very cumbersome and time-consuming to change the slitting width. Improper position of the upper and lower knives will cause the coil to break or damage the knives. In addition, electret, inspection and then slitting, not only time-consuming and labor-intensive, but also the resistance of the filter material will also change, it is difficult to guarantee the quality of the filter material
