What Are The Reasons For Low Rotational Speed Of A Sewing Machine? And How To Deal With It?
Bag sewing machines play a crucial role in various industries, such as fashion, furniture production, and automotive production. As a critical part of bag sewing machines, the stitching speed of the overlock sewing machine directly affects the efficiency and quality of the production process. However, sometimes the sewing machine's stitching speed is slow and subpar, and it may lead to production delays, poor productivity, and low-quality products. In this article, we will explore the possible causes of low stitching speed in an overlock sewing machine and provide constructive solutions to boost the stitching speed.
1. Machine Age and Maintenance
The overlock sewing machine may experience low stitching speed if it is old and not performing at optimal levels. Over time, the machine's mechanical parts may wear out, leading to increased friction and poor machine performance.
Solution: Regular maintenance of the sewing machine, such as cleaning and oiling its parts, ensures optimal machine performance. Where possible, the machine operator should replace worn-out parts to improve stitching speed.
2. Machine Tension Problems
Another factor that may lead to low stitching speed on an overlock sewing machine is machine tension. The tension of the threads, both upper and lower, needs to be just right, or the machine will experience low stitching speed or even stop working completely.
Solution: The machine operator should ensure that the machine is correctly threaded, with the upper and lower threads adjusted to the recommended tension levels. It may be helpful to carry out a tension test to determine the ideal tension setting for different fabrics.
3. Thread Problems
Sometimes, the type and quality of thread used on an overlock sewing machine may lead to low stitching speed. Poor-quality thread may frequently break or cause the machine to jam, slowing down stitching speed significantly.
Solution: The machine operator should choose high-quality threads that are compatible with the machine's specifications and the intended fabric's weight and texture.
4. Needle Problems
The size, type, and state of the needle used on an overlock sewing machine affect stitching speed. If the needle is the wrong size or dull, it will not penetrate the fabric effectively, leading to slower stitching speed.
Solution: The operator should ensure that they use the correct needle size and type for the intended fabric and replace the needle regularly.
5. Fabric Type and Alignment
The type of fabric used on an overlock sewing machine, and its alignment, also affects stitching speed. Thick or heavier fabrics may cause the machine to slow down, while misalignment may cause the thread to break, leading to lower stitching speed.
Solution: The operator should ensure that they use appropriate fabric types and align the fabric correctly, as per the machine's recommendations.
6. User Errors
Finally, stitching speed may be low due to operator error. For example, if the operator does not maintain a consistent rhythm while feeding fabric into the machine, it may cause the machine to slow down.
Solution: The machine operator should undergo proper training on operating the machine and ensure they are following the correct procedures.
In conclusion, low stitching speed in an overlock sewing machine may arise due to several factors related to the machine, thread, needle, fabric, and user error. However, proper maintenance, thread, needle selection, fabric, and alignment, as well as proper user training, can help boost stitching speed. To maximize productivity and ensure high-quality products, operators should carry out routine checks and maintenance of the machine and eliminate any issues that may hamper optimal machine performance.
