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, a heating pipe, a centrifugal fan and a curing table, wherein the curing table supports workpieces, the heating pipe is located above the curing table, the centrifugal fan is located above the heating pipe, and the impeller shaft of the centrifugal fan is connected with the output shaft of amotor. The centrifugal fan is characterized in that at least two uniformly distributed keyways are arranged on the output shaft of the motor, the impeller shaft is provided with convex keys matched with the keyways, and the impeller shaft and the motor output shaft are in a plug-in fit connection with the corresponding keyways through the convex keys. According to the epoxy resin curing furnace,the motor output shaft and the impeller shaft are connected with the keyways through the convex keys in a matched mode so that the two shafts can be subjected to balanced centrifugal force in the process of rotating, it is ensured that the force is stably transmitted, and the air volume 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...
