Problems solved by technology

However, when the motor is running at high speed, it will generate great resonance and noise. This is caused by the insufficient connection between the output shaft of the motor and the impeller shaft and the unstable force. On the other hand, it affects the air volume of the fan. The utilization rate of the air volume will decrease with the increase of the speed, which will directly lead to the heat transfer efficiency, that is, the curing efficiency will decrease.

Abstract

The invention discloses an epoxy resin curing furnace. The epoxy resin curing furnace comprises a box body, heating pipes, centrifugal fans and a curing table for bearing workpieces. The heating pipes are arranged above the curing table. The centrifugal fans are located above the heating pipes. Impeller shafts of the centrifugal fans are connected to motor output shafts of the centrifugal fans. The epoxy resin curing furnace is characterized in that each one of the motor output shafts is provided with at least two key grooves distributed uniformly; the impeller shafts are provided with raised keys matching with the key grooves; and the impeller shafts are in a plug-in fit connection relationship with the motor output shafts by the raised keys and the corresponding key grooves. The impeller shafts are in a plug-in fit connection relationship with the motor output shafts by the raised keys and the corresponding key grooves and thus the impeller shafts and the motor output shafts are acted upon by a balanced centrifugal force during rotation so that force transmission is stable and air quantity stability is improved.

Description

technical field [0001] The invention relates to a curing furnace, in particular to an epoxy resin curing furnace. Background technique [0002] Curing ovens are containers used for curing in parts heating, resin curing and drying production processes in the electronics industry and various other industries. Curing furnaces are divided into resin curing furnaces and metal curing furnaces. Among them, the resin curing furnace is a curing treatment process for curing the resin, heating the workpiece to a higher temperature, and performing constant temperature treatment, in order to enhance the stress of material bonding. [0003] In the prior art, the resin curing furnace includes a box body, a heating device, a centrifugal fan 101 and a curing table carrying workpieces. The heating device (heating pipe) heats the workpieces on the curing table to cure the resin on the surface of the workpieces. Wherein the heat of the heating device is transmitted to the surface of the workp...
