Maintenance Schedule Of Desizing Machine And Route Of Utilities Applied For Technical Operations

Objects:

  1. To observe the machine.
  2. To learn about the controlling points.
  3. To know about the mechanism.
  4. Overall maintenance of tank.

Function of desizing machine:

Desizing is a process of removing starch from the fabric.

Main parts:

  1. Desizing tank,
  2. Free roller,
  3. Winch roller,
  4. Tension roller,
  5. Squeezing roller.

Manufacturer of the machine: MOTHER & PLATTS LTD.

Controlling points of the machine:

The machine should be maintained in several points of view. These points are mentioned on the next.

  1. Squeezing roller:- The upper roller of the squeezing roller is soft and that of the lower roller is hard. The speed of the transmission of the cloth through the squeezing roller should be adjusted according to the quality of the fabric.
  2. Concentration of the bar:- The concentration of the bar should be controlled according to the quality of the fabric.
  3. Roller movement:- Different free and guide roller should be moved easily. We have to look about that.
  4. Air control:- Air has to be controlled to maintain the pressure of squeeze roller.
  5. Water, steam line:- Water supply and steam supply line have no linkage and proper flow of water and steam should be maintained.
  6. Proper fabric path:- In case of desizing proper path should be followed by the different roller. In is also maintained properly.
  7. Proper temperature:- In case of enzymatic agent the proper temperature should be maintained in the bath.

Machine condition:

This machine was idle due to various defects. The defects are on mechanical defects on rollers. These are rushed become fixed for it. The utility supply pipes are broken or not connected. The electrical motor connected for pressure inducing is defective. The pressure regulator of the machine is worn out. Above all the machine became a skeleton of a singeing-desizing machine.

Utilities:

  1. Water,
  2. Steam,
  3. Electricity
  4. Gas.
