Control system of disc plucker

Abstract

The invention discloses a control system of a disc plucker. The control system is characterized in that a PLC (programmable logic controller), a text display as well as buttons with signal lamps are added to an electrical cabinet of the disc plucker, the PLC is adopted as a core for control, falling period and acting time of a beater of the disc plucker are adjusted precisely by a human-computer interface through the text display, a circuit is concise and reliable, working is stable, the period of automatic falling actions and duration of each falling action of the beater of the disc plucker,namely, the falling period and the acting time are adjusted conveniently according to quantity of cotton carding beds, and sufficient mixing and precise gripping are realized; the falling period and the acting time of the beater of the disc plucker are adjusted conveniently according to tightness degrees of new and old cotton bales, labor intensity of an operator is reduced, and equipment accidents are avoided.

Description

technical field [0001] The invention relates to a control system, in particular to a control system of a disc bale bale machine, and belongs to the electrical technical field of textile equipment. Background technique [0002] The simple blowing and carding unit is generally transformed on the basis of the original domestic blowing unit and carding machine. Each manufacturer is equipped with different numbers of cards according to the supply of semi-finished products required in the subsequent process. The cotton machine is the most advanced equipment of the simple blowing and carding unit. The main task of the equipment is to fully mix and finely grasp the raw materials. It is possible to improve the operating rate of the cotton catching trolley to the greatest extent; the existing disc catching cotton machine mainly adjusts the operating rate of the trolley by adjusting the automatic descending depth of the catching cotton beaters each time. That is, the length of the des...

Problems solved by technology

[0002] The simple blowing and carding unit is generally transformed on the basis of the original domestic blowing combined unit and carding machine. Each manufacturer is equipped with different numbers of cards according to the supply of semi-finished products required in the subsequent process. The cotton machine is the most advanced equipment of the simple blowing and carding unit. The main task of the equipment is to fully mix and finely grasp the raw materials. It is possible to improve the operating rate of the cotton catching trolley to the greatest extent; the existing disc catching cotton machine mainly adjusts the operating rate of the trolley by adjusting the automatic descending depth of the catching cotton beaters each time. That is to say, the duration of the descending action is controlled by the time relay. The main disadvantage is that the trolley will automatically descend once every time the trolley walks around. It will soon be able to satisfy the cotton supply in the rear channel. The operating rate of the trolley is too low. The batter ribs press the cotton bale too tightly, and the running of the trolley is blocked. If the operator does not deal with it in time, it will cause equipment accidents in serious cases; at the same time, the existing disc bale machine uses a time relay to control the time of the beater's downward movement The length is not accurate enough, especially the bales of new and old cotton have different degrees of tightness. When it is necessary to fine-tune the descending depth of the beater in time, it is even more difficult to use the time relay to make precise adjustments.
