Description

Technical Field

[0002] Spinning is a synthetic fiber that is commonly used to make various textiles. It has excellent physical and chemical properties. Spinning filaments can be made into different fiber finenesses and structures through different spinning processes. They are suitable for the manufacture of clothing, household goods, industrial products and other fields. During the production process of spinning, some spinning components need to be preheated, which can improve the tensile properties and thermal stability of the spun fibers. It also helps to reduce the change in tensile force of the fibers during spinning and subsequent processing.

[0003] The spinning component preheating furnace currently used in the spinning production workshop is an electrically heated drawer preheating furnace. There is a large inner cavity in the furnace. There are 3 rows of 15 drawer-type preheating devices distributed from top to bottom in the inner cavity. Each drawer is connected to the cavity by welding. There is a drawer box with a pulley on the drawer. The components are placed in the drawer box. 15 drawers are located in one cavity at the same time and controlled by a temperature controller.
