Description

technical field

[0001] The invention relates to a drawing hot box device, especially a drawing hot box device used in spinning, which is an improvement to the existing drawing hot box device. Background technique

[0002] The drawing hot box is a device often used in spinning. It is a device that heats the tow and then draws it. Existing drawing hot box device as shown in Figure 2, comprises: one end has tow inlet 12 and air inlet 10 and the other end has the tunnel 14 of tow outlet 13 and air outlet 11, also has an end to be provided with air outlet and The other end is provided with the air duct 15 of air inlet, and the air inlet of air duct and the air outlet are connected with the air outlet 11 of tunnel and air inlet 10 respectively; heater. It can be seen that the existing drawing hot box device uses a centrifugal fan to heat the hot air to the tow in a circular manner, which can not only reduce the waste of heat energy but also make the air temperature relatively st...
