[0003] In the prior art, the residue removal operation is carried out by the way of drum screening, but this way needs to increase a set of rolling type screening machine, which not only increases the length of the waste plastic bottle recycling production line, but also increases the equipment cost of the recycling production line. SUMMARY
[0004] The utility model discloses a transmission belt with magnetic separation function for conveying the waste plastic bottle after label removal or crushing to the next process and removing the metal waste residues and iron filings in the conveying process.
[0005] The transmission belt comprises at least one belt, a belt transmission mechanism composed of two groups of parallel rollers, a driving motor for driving one of the rollers to rotate actively and a tensioning wheel arranged at the side of the belt.
[0006] A scrap collecting disc is arranged below the magnetic roller, and the area of the scrap collecting disc covers the belt part between the tensioning wheel and the magnetic roller, for collecting the iron filings falling from the belt.
[0007] The outer end of the tensioning wheel is provided with convex ridges arranged uniformly around the circumference, so that the belt part between the tensioning wheel and the magnetic roller shakes up and down when the belt is conveyed, and the iron filings adhering to the surface of the belt are shaken off and fall into the scrap collecting disc.
[0008] Further, a scrap discharging port is arranged below the scrap collecting disc, and a detachable scrap collecting box is arranged below the scrap discharging port, which is sleeved on the outside of the scrap discharging port and used for receiving the iron filings from the scrap discharging port.
[0009] Further, convex shafts are arranged at the two ends of the outside of the scrap discharging port, and correspondingly, open hooks are arranged above the scrap collecting box, which are hung on the convex shafts, and in addition, handles are arranged at the side of the scrap collecting box, which are convenient for the operator to hold and take off the open hooks from the convex shafts.
[0010] The technical effects of the utility model lie in: first, structure simplification and cost reduction, the magnetic separation function is integrated on the conveying belt, the independent drum screening equipment is saved, the production line length is shortened, and the equipment investment cost is reduced; second, the magnetic wheel has the adsorption function for metal waste residues and iron scraps, realizes the metal separation in the conveying process, and the magnetic adsorption has certain penetrability, can make the metal waste residues and iron scraps mixed in the waste plastic bottles be adsorbed on the outer surface of the belt when passing through the roller at the end of the conveying direction, and after the rotating belt leaves the roller at the end of the conveying direction, the magnetic adsorption force disappears, and the metal waste residues and iron scraps fall into the scrap receiving tray; third, the convex ridge of the tensioning wheel makes the belt generate high-frequency shaking, combined with the covering design of the scrap receiving tray, the iron scrap falling rate is improved to 98%, and sticking and remaining are avoided; fourth, the scrap discharging port and the scrap collecting box are connected through the convex shaft buckle, cooperate with the open hook and the handle, and the scrap collecting box can be disassembled and assembled by one hand, and the cleaning efficiency is improved.
