Description

Technical Field

[0001] The utility model relates to the technical field of polymer material processing, and particularly relates to a vertical crusher for polymer material processing. Background Art

[0002] Polymer materials, also known as polymer materials, are materials based on high molecular compounds. They are composed of compounds with relatively high molecular weights, mainly including rubber, plastics, fibers, coatings, adhesives, and polymer matrix composites, etc. Polymer materials can be divided into natural polymer materials and synthetic polymer materials according to their sources, and can be divided into rubber, fibers, plastics, polymer adhesives, polymer coatings, and polymer matrix composites, etc. according to their characteristics. The vertical crusher is an adjustable fine crushing equipment without sieve bars optimized and designed on the basis of absorbing advanced fine crushing equipment technologies at home and abroad. It is widely used in the field of polymer material processing, can process various types of polymer materials, and has the advantages of strong adaptability, high crushing efficiency, and low energy consumption. The working principle of the vertical crusher is mainly based on the impact, extrusion, and shearing effects between the material and the high-speed rotating components. The material enters the casing from the feed inlet and collides with high-speed rotating components such as chain hammers and cutter discs. After multiple impacts, extrusions, and shears, the material is crushed into fine particles or powders and discharged from the discharge outlet. The vertical crusher for polymer material processing is a crushing equipment specially designed to process polymer materials. It can efficiently crush polymer materials such as plastics and rubbers into fine particles or powders to meet the needs of subsequent processing or recycling.

[0003] The current vertical crushers for polymer material processing can basically meet people's usage requirements, but there are still some problems, which are specifically described as follows:

[0004] 1. When the vertical crusher for polymer material processing crushes materials, due to the different sizes and hardnesses of the materials, and the crushing hammers are fixed on the rotating shaft, it will cause the impact force between the hammer heads and the materials to be too large during hammering, resulting in situations such as wear and fracture of the crushing hammers, leading to a reduction in work efficiency and an increase in costs.

[0005] 2. The materials processed by the vertical crusher for polymer material processing are mostly fine particles, which are difficult to collect and clean, easily cause pollution to the working environment, and will also affect the health of workers if inhaled into the body. Summary of the Utility Model

A plurality of groups of first rotating disks and second rotating disks are arranged at equal intervals on the rotating shaft. Each group of the first rotating disk and the second rotating disk is connected by a connecting rod, and a crushing hammer is arranged in the middle. The crushing hammer can rotate on the connecting rod. When encountering larger materials, it will unload force in the opposite direction of rotation, achieving the purpose that the vertical crusher for polymer material processing can avoid phenomena such as the fracture and serious wear of the crushing hammer.

[0019] Through the design of the discharge port with a larger upper part and a smaller lower part, the relatively fine polymer materials after crushing are collected into the aggregate box. An observation window is provided on the aggregate box, through which the discharge situation and the material collection amount can be viewed. The aggregate box can be disassembled from the discharge port, facilitating the emptying and cleaning of the aggregate box, achieving the purpose that the vertical crusher for polymer material processing is convenient for collecting waste materials.
