A solid resin crusher

Abstract

The invention discloses a crusher. The crusher comprises a feeding trough, a material pressing mechanism, a material pushing mechanism, a fine grinding trough, a fine crushing mechanism, a hydraulic system and a control system, wherein the material pushing mechanism is positioned on one side of the feeding trough; the fine grinding trough is positioned on the other side of the feeding trough; the material pushing mechanism is provided with a material pushing rod for continuously supplying a solid material to the fine grinding trough; the fine crushing mechanism comprises a machine frame, a movable jaw, an eccentric shaft, a fixed tooth plate, a movable tooth plate and an eccentric driving motor; a discharge port is formed in the lower part of the fine crushing mechanism; a material receiving bag is arranged below the discharge port; the material pressing mechanism, the material pushing mechanism and the fine crushing mechanism are controlled by the control system and connected. The crusher performs primary crushing through the material pressing mechanism, and then performs fine crushing through the fine crushing mechanism, so that a continuous full-automatic crushing operation is achieved and the working efficiency is greatly improved, and a high-quality fine material can be obtained after secondary crushing and finally the product quality is improved.

Description

technical field [0001] The invention relates to a crusher and a crushing method, which can be used for fine crushing of solid raw materials in the prepreg manufacturing process. Background technique [0002] In the prior art, solid raw materials, such as solid resins and fillers, are used in the prepreg manufacturing process, and these solid raw materials need to be finely crushed before they can be used. At present, the crushing of large particles of solid resin is mainly carried out by manual knocking, which not only produces a large amount of dust, resulting in a poor working environment, but also has low efficiency and high cost of manual knocking; in addition, this The operation method in a large environment is not conducive to the control of subsequent glue impurities, which seriously affects the mass production of new products and the quality improvement of high-performance products.

Problems solved by technology

At present, the crushing of large particles of solid resin is mainly carried out by manual knocking, which not only produces a large amount of dust, resulting in poor working environment, but also has low efficiency and high cost of manual knocking; in addition, this The operation method in a large environment is not conducive to the control of subsequent glue impurities, which seriously affects the mass production of new products and the quality improvement of high-performance products.

[0003] In response to the above problems, people began to use commonly used crushers in other industries, but in practical applications, it was found that the use of a single crusher still has the following problems: (1) Due to the different sizes of solid resins, the particle sizes vary greatly. Materials, the existing crushers cannot be crushed directly, and need to be crushed manually, and then put into the crusher. Obviously, manual work will still bring about problems such as low efficiency, difficulty in controlling internal impurities, and difficulty in improving quality; ( 2) Since the capacity of the crusher is fixed, after completing a batch of crushing operations, it is necessary to manually take out the crushed materials and then add new materials to be crushed, so complete automation cannot be achieved and the efficiency is poor; ( 3) For the crusher, a small amount of material is the best for crushing. However, in practical applications, in order to increase work efficiency, the crusher is often filled up, that is, it runs at full capacity, resulting in crushed materials uneven, poor quality
