Mode of Y-shaped drum implementing control drum overnight and its automatic controller

Abstract

This invention relates to a way of implementing control drum overnight by Y shape rotor that divides case and its automatic control equipment, exsertion end of its weight-bearing axis is fixed with work body that turn synchronously with drum body, outside circle of work body is inlayed plateau that corresponds to chamber and separator place of drum body, corresponding place of plateau is installed with proximity switch that detects drum body place, its status signal is switched in PLC input end, PLC outlet end connects control terminal of frequency changer, power source outlet end of frequency changer connects amphenol connector of electromotor, thumber and control contacter of electromotor connect PLC outlet end, PLC input end connects contact of time relay and counter respectively, one end of control contacter and time relay connects one end of power supply, the other end connects the other end of power supply respectively by PLC outlet end. It makes drum body slowly turn several cycle every a part time, one case that is in them is stopped under inferior part by turns, make drum body have the function of 'control drum overnight'.

Description

technical field [0001] The invention relates to a method for realizing overnight drum control with a Y-shaped grid drum used for leather processing, and also relates to an automatic control device for realizing "drum overnight control" for a Y-shaped grid drum. Background technique [0002] The stainless steel Y-shaped compartment drum for leather processing has a frame, a circular drum body, a support shaft, a motor with a brake for driving the drum body to rotate, and a transmission device. The cavity formed by the inner drum wall of the drum body is divided into three chambers (that is, three compartments) by three perforated partitions in a "Y" shape structure. The leather is put into the three compartments and the liquid is shared. . When the drum rotates, the leather has an equal chance of being soaked or contacted by the liquid in the three compartments, so that the characteristics of the leather produced will be uniform. However, in the process of making leather, i...

Problems solved by technology

For this process, traditional wooden drums are very easy to implement since they only have one chamber

However, it is very difficult for the Y-shaped divisional drum to realize this process, because when the drum body stops rotating, the leather at the bottom of the drum body is naturally soaked in the liquid, and the leather at the upper half of the drum body is separated by a partition, so it cannot Bubbled in the liquid, it can only be exposed to the air. This defect of the Y-shaped divided drum makes it impossible to realize the process of "drum control overnight".

However, "drum control overnight" is necessary in the leather processing technology of most leather manufacturers, which greatly limits the use of Y-shaped grid drums and weakens its role, resulting in very advanced, Expensive Y-shaped drums do not work well for leather processing
