Gunpowder tea roasting machine

Abstract

The invention relates to a gunpowder tea roasting machine. The gunpowder tea roasting machine comprises a transmission assembly, a tea roasting assembly and a swinging amplitude adjusting assembly; the tea roasting assembly comprises a frying pan, an arc frying plate and a horizontal frying pan supporting crankshaft; the transmission assembly comprises a mounting sleeve, a crank and rocker mechanism and a speed reduction motor, the crank and rocker mechanism comprises a crank, a transmission connecting rod and a transmission rocker, the crank, the transmission connecting rod and the transmission rocker are connected in sequence, the crank is installed on a driving shaft of the speed reduction motor, the other end of the crank is connected with the transmission connecting rod through a bolt, and the other end of the transmission connecting rod is connected with a transmission rocker sleeve through a bolt. The transmission rocker is divided into an external threaded section and an optical axis section, the optical axis section and the transmission rocker sleeve are coaxially installed, the external threaded section and the inner thread of the mounting sleeve form spiral cooperation,and the transmission rocker is driven by a stepping motor to rotate and moves in the axis direction of the mounting sleeve to change the amplitude by which the transmission rocker drives the arc frying plate to swing. The gunpowder tea roasting machine conducts stepless adjustment on the swinging amplitude of the arc frying plate without being shut down.

Description

technical field [0001] The invention belongs to the field of tea processing machinery and equipment, in particular to a pearl tea frying and drying machine. Background technique [0002] Pearl tea is a kind of spherical tea. It is named for its round and compact shape, granular shape, green color, and heavy bones like pearls. At present, after the roasting process of pearl tea roasting equipment is completed, the tea needs to be produced manually, which is inconvenient to operate and difficult to realize continuous production. The existing pearl tea frying equipment has two gears for the swing range of the frying plate, the swing range is 75° and 90° respectively, and it is realized by manually shifting the shift fork. The disadvantage is that only the above two gears can be realized. The change of the amplitude cannot realize the frying of pearl tea with other swings, let alone the stepless adjustment of the swing of the frying plate, which limits the adaptability of this ...

Problems solved by technology

At present, the roasting equipment for pearl tea needs to produce tea manually after the roasting process is completed, which is inconvenient to operate and difficult to achieve continuous production

The existing pearl tea frying equipment has two gears for the swing range of the frying plate, the swing range is 75° and 90° respectively, and it is realized by manually shifting the shift fork. The disadvantage is that only the above two gears can be realized. The change of the amplitude cannot realize the frying of pearl tea with other swings, let alone the stepless adjustment of the swing of the frying plate, which limits the adaptability of this kind of equipment to the swing of the frying plate for the roasting process of pearl tea.

When frying different types of pearl tea, due to the different tea-frying techniques, there is a requirement for real-time changes in the swing of the frying plate. Since the gear shift requires manual operation, it is impossible to realize the automatic adjustment of the swing of the frying plate. Since there are only two swing gears position, which also limits the selectivity of the swing, and at the same time restricts the automatic production of pearl tea roasting
