Description

Technical Field

[0001] This utility model belongs to the technical field of raw material crushing devices for polyester sleeve production, and specifically relates to a crushing device equipped with a grinding structure. Background Technology

[0002] Polyester sheathing is a commonly used cable protection sleeve. Its production requires the raw materials to be crushed. If the crushed particles are too large, problems may arise in the later stages of polyester sheath preparation. Most common polyester sheathing raw material crushing devices have single or multiple crushing structures. While these structures crush the raw materials, they alone cannot completely crush them. Regardless of the crushing method, some large particles of polyester raw material will remain. These large particles are difficult to mix thoroughly with other auxiliary materials during the mixing process, leading to uneven mixing. Furthermore, incompletely crushed raw materials may cause surface defects such as streaks, spots, and bubbles on the sheath surface. Large particles may also form localized areas inside the sheath, and the properties of these areas (such as mechanical strength, heat resistance, and insulation) may differ from the overall performance, affecting the overall product performance.

[0003] In summary, the pulverizing device without a grinding structure has some problems in use, so it is hoped that a new structure can be proposed to solve the above-mentioned technical problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pulverizing device equipped with a grinding structure to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a pulverizing device with a grinding structure, comprising: a device body, a pulverizing component, and a receiving box.
