Description

Technical Field

[0001] The utility model relates to the technical field of cloth processing, in particular to a slitting knife holder for a slitting machine. Background Art

[0002] In the field of tarpaulin processing, the cutting process plays a vital role. Tarpaulins are widely used in outdoor activities, transportation, construction and other fields. Their quality and precision directly affect the performance and service life of the final product. However, most tarpaulin cutting work currently still relies mainly on manual operation. This traditional method has a high labor demand because it requires multiple workers to work together, which significantly increases labor costs. This not only increases production costs but also limits production efficiency, especially in large-scale production. At the same time, manual operation is relatively slow and cannot meet the urgent demand for efficient production in modern industry. Moreover, the inconsistency of manual operation makes it difficult to further improve production efficiency.

[0003] Inconsistencies in manual work make it difficult to guarantee cutting accuracy and quality, which in turn affects overall product consistency and yield. This inconsistency not only leads to increased scrap rates but also increases the difficulty and cost of subsequent processes. Furthermore, due to variations in manual work, product quality and consistency are difficult to guarantee, impacting market competitiveness and customer satisfaction.

[0004] Although the existing tarpaulin slitting equipment on the market has alleviated the above problems to a certain extent, its functions are relatively simple. Especially in terms of longitudinal slitting, the cutting angle of the blade of the existing equipment cannot be uniformly adjusted, resulting in inconsistent cutting effects, further affecting product quality.
