Technical Field
The invention relates to the technical field of environmental protection recovery, in particular to an environmental protection classification recovery device.
Background
The pop can belongs to recyclable waste products, the recycled pop can enter a recycling process flow after being flattened, the pop can is flattened through two sets of flattening rollers in the prior art, the flattened pop can is subjected to crushing treatment on the pop can through the double-shaft crushing rollers, crushed materials of the pop can are obtained, and the crushed materials of the pop can be used for re-smelting in a steel mill.
The distance between the double-shaft crushing rollers is fixed and cannot be adjusted in the prior art, after a batch of pop cans are processed by the double-shaft crushing rollers, a small amount of crushed materials of the pop cans can be attached to the crushing rollers, and if the crushed materials of the attached pop cans are not processed in time, the crushing efficiency of the crushing rollers can be affected in the long term.
Therefore, an environmental protection classification recycling device is urgently needed to solve the problem that the crushing efficiency of the crushing roller is low due to the fact that the double-shaft crushing roller cannot be adjusted in the prior art.
Disclosure of Invention
The invention provides an environment-friendly classifying and recycling device aiming at the defects in the prior art, and aims to solve the problem that a double-shaft crushing roller cannot be adjusted in the prior art, so that the crushing efficiency of the crushing roller is low.
In order to solve the technical problem, the invention is solved by the following technical scheme: an environment-friendly classification recycling device comprises a flattening box, wherein two groups of flattening rollers which are vertically arranged are arranged in the flattening box, the bottom of the flattening box is communicated with a conveying mechanism, the tail end of the conveying mechanism is communicated with a crushing box, the crushing box is arranged beside the side wall of the crushing box, two crushing rollers are arranged in the crushing box, one end of each crushing roller is rotatably connected with a transverse sliding device, the crushing box is also slidably connected with a bottom plate, and a first spring is connected between the bottom plate and the bottom wall of the crushing box; the bottom plate is provided with a first magnetic block, a second magnetic block which is repellent to the opposite surface of the first magnetic block is arranged in the mounting box, the second magnetic block is fixedly connected with a reciprocating device, the reciprocating device is in transmission with the transverse sliding device, and the transverse sliding device is used for adjusting the distance between the two crushing rollers; when the first magnetic block is opposite to the second magnetic block, the two crushing rollers move in a reciprocating mode in the opposite direction and in the opposite direction.
Further optimize, the lateral sliding device includes the lateral sliding groove, sliding connection has two first sliders in the lateral sliding groove, two first sliders rotate respectively to be connected the one end of crushing roller.
Further preferably, the reciprocating device comprises a rack fixedly arranged on the second magnetic block, and a second spring is connected between one end of the rack and the side wall of the installation box.
Further optimize, reciprocating device with still be connected with transmission between the lateral sliding device, transmission includes screw rod and the first gear of coaxial coupling on the screw rod, first gear with the rack toothing, sliding connection has the second slider on the screw rod, the second slider with be connected with the hinge bar between the first slider.
Further optimize, still be equipped with the discharge gate on smashing the case, the discharge gate is connected with the discharging pipe, the discharging pipe is connected with the easy open can and smashes the material collecting box, still is equipped with the valve on the discharge gate.
Further optimize, the install bin still is equipped with the stopper that is used for restricting the rack can only lateral sliding.
