1. Maintenance of steel healds
(1) Clean the steel healds from the machine manually or with a brush heald machine to remove dirt, waste wire and other dirt on the healds.
(2) Organize and straighten the steel heddles one by one, correct the shape and angle of the heddle eyes, and remove bad steel heddles.
(3) After removing the bad steel healds, replace them with good steel healds. Note that the angles of the heald eyes and heald ears should be consistent with the original ones.
(4) There must be a dedicated person in charge of the steel sheet healds to carry out inspections in accordance with the prescribed quality standards, and unqualified products should be repaired and replaced at any time.
2. Management of steel sheet healds
(1) Factory acceptance
(1) Acceptance shall be carried out in accordance with the “FZ94008-92” standard of the textile industry of the People’s Republic of China.
(2) The boxed steel healds are pierced into plates according to the same heddle eye and heddle ear angles, 500 pieces per plate, 10 plates per box, a total of 5,000 pieces, and then put into wooden boxes with stickers on the outside. Have product certificate. The packaging box and product certificate should indicate: the steel heald model, specifications, production date, quantity, manufacturer, trademark and year of manufacture. The packaging must be firm and moisture-proof to ensure that it is not damaged during transportation and storage.
(3) Verify the quantity in the box according to the quantity indicated on the certificate, and calculate the total quantity.
(4) Conduct quality inspection on the steel healds. The inspection items are as follows:
① Check the length of the steel healds, the sizes of the heald ears and eyelets and the thickness of the steel healds.
② Check the angle between the heddle eye and the heddle ear.
③ Check the surface quality and coating of the steel sheet heald.
④ Check the elasticity. Hold one end of the steel heald with your hand, hold the other end with the other hand, and bend it to 200mm into a semicircle. If it can return to its original shape without deformation after letting go, it means the elasticity is qualified. .
(2) Operation management
(1) Each time the steel heald is taken off the machine, it must be sorted and assembled.
(2) New and old steel sheet healds should be used in different grades. New steel sheet healds should be used for high-end fabrics, and old steel sheet healds can be used for low-end fabrics.
(3) Warehouse management
(1) The steel sheet halves should be placed in a drying room, which is equipped with infrared bulbs for heating and drying, has good ventilation, and has fire prevention facilities. The indoor temperature is controlled at 28 to 30°C, and the relative humidity is controlled. At 50% to 55%.
(2) Classify and stack according to model specifications.
(3) Stack the packaging boxes according to the required height to avoid pressure deformation.
(4) Put it in storage first and use it first to avoid other problems caused by long storage time.
(5) Conduct regular inspections.
