Double-shaft shredding machine

Abstract

The invention discloses a double-shaft shredding machine which comprises a box and a cutter. A crushing cavity is formed in the box. The two ends of the crushing cavity are each provided with an installing plate and a partition plate which are arranged in a spaced manner. A first gap is formed between each installing plate and the corresponding partition plate. The cutter comprises two cutter shafts, cutter bodies and multiple scraping cutter bodies. The two ends of each cutter shaft penetrate the partition plates and are in pivot joint with the installing plates in a bearing manner. Each cutter shaft is fixedly provided with the multiple cutter bodies. A second gap is formed between every two adjacent cutter bodies on each cutter shaft. Each cutter body comprises a cutter base and a cutting blade. The multiple cutting blades are distributed on the cutter shafts in a spiral line manner. Each scraping cutter body comprises a scraping cutter base and a scraping blade. Each scraping blade is arranged in one second gap in a one-to-one corresponding manner. The double-shaft shredding machine is high in cutting force. The scraping blades can be used for removing materials remaining on the cutter shafts, and the cutter shafts can operate more smoothly. Meanwhile, the situation that materials enter a bearing and damage the bearing is avoided.

Description

technical field [0001] The invention relates to the technical field of material processing equipment, in particular to a double-shaft shredder. Background technique [0002] The shredder is mainly used for the crushing of materials, and the double-shaft shredder is one of the shredders, which mainly reduces the size of the material through shearing, tearing and extrusion. With the rapid development of the environmental protection industry, this shredder is widely used in the crushing of waste plastics, waste rubber, wood and other large-volume waste, so that the waste can be recycled and reused. The existing double-shaft shredders are usually pivotally connected with two cutter shafts in the crushing chamber of the box body. The two ends of the cutter shaft are pivotally connected to the two ends of the crushing chamber through bearings. The body rotates to shear, squeeze and tear the material, so that the crushed material enters the recovery area. However, in the process ...

AI Technical Summary

Problems solved by technology

However, in the process of material crushing, the sheared material is easily bonded to the cutter shaft, which affects the rotation of the cutter shaft; and the cutting force of the cutter body on the cutter shaft is not enough, resulting in low shredding efficiency; The material or crushed liquid is easy to enter the bearings at both ends of the cutter shaft from the crushing chamber, thereby damaging the bearings and hindering the operation of the cutter shaft
