Description
Technical Field
[0001] The utility model relates to the technical field of cotton candy machines, in particular to a burner device and a cotton candy machine. Background Art
[0002] Marshmallow is a popular dessert. Currently, it can be made and sold through an automated marshmallow machine without manual operation. The control module of the marshmallow machine can automatically make marshmallows according to the program settings, and has been widely used in public places such as shopping malls. A marshmallow machine generally has a burner device, including a burner and a fixed frame. The burner is generally pivoted to the fixed frame through a rotating shaft, and can be driven by a motor to cooperate with a transmission mechanism (such as a synchronous belt mechanism) to drive the rotating shaft machine burner to rotate at high speed. Its working principle is to throw out the heated and melted syrup in the burner through a high-speed rotating burner to form sugar threads, and then use a bamboo stick to wind up the sugar threads to complete the production of marshmallows. However, the existing marshmallow machine has the following problems: the control module of the marshmallow machine generally obtains the rotation state data of the burner by collecting the speed data of the motor. When the transmission mechanism is abnormal (such as the synchronous belt slipping) or other problems occur, it will cause misjudgment; in addition, if the rotation state of the burner is abnormal, it is impossible to quickly determine whether the problem is with the motor or the transmission mechanism.
