The utility model relates to the technical field of plate bending machines, in particular to an anti-springback plate bending machine which comprises a supporting table, an upper roller, a lower roller and an anti-springback assembly. The upper roller and the lower roller are arranged in an inner cavity of the supporting table. According to the anti-springback plate rolling machine, an electric telescopic rod is started to drive a mounting plate to move, the mounting plate drives an anti-springback block to move, so that the position of the anti-springback block is adjusted up and down, meanwhile, a motor is started to drive a lead screw to rotate, the lead screw drives a sliding block to slide along the inner wall of a sliding groove, and therefore the sliding block drives a connecting plate to move; and the connecting plate drives the mounting plate and the anti-springback block to move, so that the position of the anti-springback block is horizontally adjusted, the anti-springback block abuts against the plate, the bent plate is limited from the outer side, the springback phenomenon of one end of the rolled plate is effectively prevented, and convenience is brought to follow-up operation of operators.

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.

The plastic spraying equipment with the positioning function comprises a placing plate, a controller, a plastic spraying tank, a fixing belt, a locking mechanism and a positioning block, the top of the placing plate is fixedly connected with the bottom of the controller, the top of the placing plate is movably connected with the bottom of the plastic spraying tank, and the left side of the controller is fixedly connected with the right side of the fixing belt. Through the cooperative use of the placement plate, the controller, the plastic spraying tank, the fixing belt, the locking mechanism, the positioning block and the positioning mechanism, the problems that when the spraying machine is moved, due to the fact that the road surface is uneven, the spraying pipe inclines and collapses, the equipment is prone to being damaged, the spraying tank cannot be fixed through existing equipment, and the spraying efficiency is high are solved. In order to stably fix the spraying tank when the spraying tank is moved or used, the plastic spraying equipment with the positioning function is provided, the spraying tank is fixed through a fixing belt, adjustment is carried out at any time according to different sizes of the spraying tank, and the applicability of the plastic spraying equipment is improved.

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.

The invention discloses a battery folding device and battery processing equipment; when the battery is folded, the pre-folding device performs the first bending of the bonding section of the battery in the direction close to the body, and then the battery is transferred to the fine folding station through the transfer device, and then the battery body is clamped by the clamping device to make the battery pass through the through hole. In this process, the bonding section is squeezed and bent by the hole wall of the through hole, and the folding process of the bonding section is completed; wherein, the bonding section is first bent by the pre-folding device to reduce the deformation amount of the bonding section when passing through the through hole, and then the bonding section is squeezed by the hole wall of the through hole to perform the second bending in the direction close to the battery body, so as to avoid the bonding section from rebounding due to the excessive folding angle during the final bending; at the same time, the aperture size of the through hole does not need to consider the size error when the upper and lower molds are closed, and can better fit the battery body, so that the bonding section is closer to the battery body, thereby improving the production quality of the battery.
