A uniform material distribution control method for reciprocating feeding and distributing cranes

Abstract

The invention relates to a uniform spreading control method for a roundtrip feed distribution travelling crane. The uniform spreading control method comprises the following steps of setting the rangeof the belt motor frequency F<belt> and the walking motor frequency F<walking motor> to be 20-50 HZ; according to the formula relation between the walking speed V<walking motor> and the walking motorfrequency F<walking motor> and frequency that V<walking motor> is equal to K1*F<walking motor> and V<belt> is equal to K2*F<belt>, obtaining K1 and K2 on average; setting the flow of a product A as QAand the walking motor frequency as F<walking motor A>, wherein when the motion directions are the same, V total=K1*F<walking motor A>+K2*F<belt A same>, when the motion directions are opposite, the Vtotal is equal to K2*F<belt A opposite>-K1*F<walking motor A>, and F<belt A same> and F< belt A opposite> are obtained; and setting the flow of a product B as QB, obtaining F<walking motor B> according to the formula that F<walking motor B> is equal to F<walking motor A>*QB / QA, and further obtaining F< belt B same> and F< belt B opposite>. The method can solve the problem of inconsistent speed ofmaterials relative to a discharging port in the roundtrip process of the distribution travelling crane, and improves the uniformity of material laying.

Description

technical field [0001] The invention belongs to the field of tobacco shred production process control, and in particular relates to a method for uniform material distribution control of a reciprocating feed distribution drive. Background technique [0002] In the production of shredded tobacco, the feeder has the functions of storing materials, buffering flow and evenly mixing materials, and is widely used in various processes. The feeding mechanism of the feeder is mainly composed of a distributing crane and a spreading crane. The material enters the distributing crane through a conveyor belt, and is sent to the spreading crane during its round trip process, and finally the material falls into the feeder. [0003] At present, the feeding port of the conveyor belt is in a fixed position, and the distributing carriage below it runs back and forth, but the belt of the distributing carriage runs in a single direction. When the distributing vehicle and the belt move in the same...
