A PLC-based dual-spring rotary coconut meat digging device and its working method

Abstract

The invention relates to Programmable Logic Controller (PLC)-based double-spring rotary type coconut meat digging equipment and a working method thereof. The equipment comprises a power driving device, a blade cantilever device and a conehead thread device, wherein the power driving device comprises an electromotor, a loop sleeve, a thread main shaft, a coupling, a bevel gear and two pairs of concentric helical gears; the blade cantilever device comprises a spring A, a spring B, a steel small cup, a fixing ring sleeve, a connecting rod, a blade bearing arm, a telescopic rod and a blade group; the conehead thread device comprises a grater cone and a pressure sensor; the thread main shaft is driven by the electromotor to rotate to drive the blade group and the grater cone to rotate; coconut meat can be cut in the rotation process of the blade group; coconut meat which cannot be cut by the blade group is grated out by the grater cone; positive and negative operation of the electromotor is controlled according to a pressure signal. The PLC-based double-spring rotary type coconut meat digging equipment is simple to operate, the coconut meat digging security and efficiency are improved, completeness of coconut shells is ensured, the comprehensive utilization rate of coconuts is increased, and the automation degree of coconut meat digging is greatly increased.

Description

technical field [0001] The invention relates to a coconut meat digging device and method, in particular to a PLC-based double-spring rotary coconut meat digging device and a working method thereof, which belong to the field of coconut meat processing. Background technique [0002] Coconut meat is an important raw material for coconut milk beverages, coconut flakes and other coconut meat foods. At present, there are few research reports on coconut meat digging machines at home and abroad, and the separation technology of coconut meat and coconut inner shell is not yet mature, and is still in the stage of manual labor and semi-mechanized production. A kind of portable coconut husk scraping coconut meat knife (patent number: CN102357022A) of Zhang Min's invention, its essence is by the improvement of knife, replaces big knife (wood chopping knife or big kitchen knife), is easy to carry. However, manually digging coconut meat is inefficient, labor-intensive, and prone to safety...
