Accurate flow control unit for tea production line

Abstract

An accurate flow control unit for a tea production line comprises a feeding hopper, a power mechanism, an elastic push rod mechanism, a conveying belt and an adjusting mechanism. The feeding hopper isprovided with a discharging port, and the conveying belt is arranged on the lower side of the discharging port. An adjusting end at the end of the elastic push rod mechanism is inserted into the discharge port, a push rod of the elastic push rod mechanism reciprocates under the action of the elastic force of the push rod mechanism and the power mechanism, and the adjusting end reciprocates alongwith the push rod to adjust the opening degree of the discharge port. The adjusting mechanism is used for adjusting the thrust of the power mechanism to the elastic push rod mechanism according to thebearing load of the conveying belt so as to change the telescopic amplitude of the adjusting end in the discharge port. According to the invention, the bearing load of the conveying belt is changed along with the discharging speed of the discharge port. By means of the adjusting mechanism and the power mechanism, the opening degree of the discharging port is synchronously adjusted along with thechange of the bearing load of the conveying belt, the bearing stability of the conveying belt is achieved, and therefore stable discharging of the discharging port is guaranteed.

Description

technical field [0001] The invention relates to the field of tea processing equipment, in particular to an accurate flow control unit for a tea production line. Background technique [0002] The feeding uniformity and accuracy of the key equipment in the tea production line directly affect the quality of tea processing. Since the current tea production line does not have a flow control unit, the feeding on the conveyor belt is uneven, such as greening, shaping, and baking. Due to the uncertainty of feeding in the process, there is often a waiting state of too much incoming material or temporarily no material in the relevant equipment. When the incoming material suddenly increases, it will cause defects such as insufficient finishing, uneven shape or insufficient baking; When the incoming material suddenly decreases, it will cause burnt flakes, broken tea and burnt. All of the above are related to the current production line that only relies on the belt speed of the conveyor...

[0002] The feeding uniformity and accuracy of the key equipment in the tea production line directly affect the quality of tea processing. Since the current tea production line does not have a flow control unit, the feeding on the conveyor belt is uneven, such as greening, shaping, and baking. Due to the uncertainty of feeding in the process, there is often a waiting state of too much incoming material or temporarily no material in the relevant equipment. When the incoming material suddenly increases, it will cause defects such as insufficient finishing, uneven shape or insufficient baking; When the incoming material suddenly decreases, it will cause burnt flakes, broken tea and burnt, etc.

All of the above are related to the current production line that only relies on the belt speed of the conveyor belt to control the feeding, and the output of the production link is caused by non-uniform output. Flat loss) caused by feeding
