Description

Technical Field

[0002] Long glass fiber is one of the commonly used materials in the manufacturing industry. Pelletizers are used in the production process of long glass fiber. Pelletizers are usually used to cut long glass fiber materials into granules for subsequent processing and product production of long glass fiber.

[0003] When the long glass fiber is pelletized, it is first transmitted to the inside of the pelletizer through the feed port, and at the same time, the long glass fiber is cut into pellets by the cutter inside the pelletizer, so as to complete the pelletizing operation of the long glass fiber; however, the existing pelletizer will produce particles of different sizes when pelletizing the long glass fiber, and some impurities or incomplete particles may be generated during the cutting process. Due to the lack of a screening mechanism, the impurity particles, large-sized particles and small-sized glass fiber particles will be mixed together after the cutting is completed, making it difficult to classify them, thereby affecting the pelletizing quality.

[0004] In summary, the utility model provides a pelletizer for long glass fiber production to solve the above problems. Utility Model Content
