The utility model relates to a non-reverse fast closing switch of an electrical switch. The device comprises a static feeler lever, a movable feeler lever, a magnetic piece, a push piece, a lock groove, a lock piece and an elastic piece I, wherein the magnetic piece can be used for establishing a magnetic field driving force for switching on the switch; the push member is in a magnetic field range of the magnetic member and can cooperate with the magnetic member to drive the switch to close. The locking groove is formed in the side wall of the movable feeler lever; the locking piece is arranged on the side of the movable feeler lever, the movable feeler lever is locked when the locking piece is inserted into the locking groove, and the movable feeler lever is unlocked when the locking piece retreats from the locking groove. The first elastic piece provides driving force for closing of the switch. And after the magnetic piece and the push piece are attracted, the static contact rod and the movable contact rod are stably switched on, so that the rebounding phenomenon of the contact is avoided, and the switching-on speed and the switching-on effect of the switch are guaranteed. After the moving feeler lever is unlocked, the moving feeler lever can perform quick closing action under the action of magnetic field force between the magnetic piece and the push piece and the elastic force of the first elastic piece, so that quick closing of the switch is realized.

This invention discloses a wrapping and folding system for processing rock wool composite panels and its usage method. The system includes a first transmission device and a second transmission device arranged sequentially. Lateral limiting plates are installed on both sides of the first and second transmission devices. A closing support device, a folding and pressing device, and a layering device are installed on the first transmission device. The folding and pressing device includes a first gantry support, a horizontal support, a pressing roller, an outer folding roller, and an inner folding roller. A bidirectional folding device is installed on the second transmission device. The bidirectional folding device includes a second gantry support, a vertical adjustment component, a support horizontal plate, a drive mechanism, and a folding roller shaft. The usage method includes parameter adjustment and installation of the glass fiber mesh. This system can achieve continuous natural wrapping and inward extrusion and folding of the glass fiber mesh, improving the tightness of the glass fiber mesh wrapping, ensuring the yield rate, having good adjustability, adapting to products of different specifications, and being highly practical.
