Before turning on the Hot Air Stenter, the staff, you forgot to check to ensure that it can be used stably. Then set the temperature according to the process requirements, and then turn on the circulating fan. During the heating stage, when the speed of the main engine reaches 15m/min and reaches the predetermined temperature, the cloth can be operated.

When loading the cloth, it should be noted that the ends should be as flat as possible. When starting the host of the Hot Air Stenter, you should ring the bell to notify the operator at the rear of the car. When the cloth reaches the rear of the car, wear the cloth at a slow speed and tighten the fabric. The front staff should be prepared to cooperate. Remember, the position of the machine's cloth in and out should ensure that its safety cover is intact and stable to prevent accidents.

During operation, if any problems are found, the equipment should be shut down immediately without negligence. In addition,

The grey cloth must be sewn and knotted to prevent damage to the rubber roller and cause safety accidents. If the operation is over, the Hot Air Stenter equipment should be shut down as required, and the cooling requirements should also be notified to the hot-load heat-conducting oil furnace before shutting down. Stop the circulating fan first and open the door to cool down. If its temperature drops to 80℃, it can stop.

In the process of daily operation, the staff need to maintain good working habits, especially to check the heat transfer oil pipeline in the oven regularly. For example, if there is oil leakage, it should be dealt with in time. In addition, the Hot Air Stenter should also be disinfected and taken care of and kept in a stable working condition.

It should be noted that whether the disinfection operation is still adding lubricating oil, it should be carried out after the equipment stops running. If the open rotary screen printer is in operation, do not wipe the chain, brush the needle plate, wipe the roller, etc. to prevent accidents.

　　 (1), the thickness of the printing plate film

　　 The thickness of the printing film on the printing surface of the screen printing plate affects the thickness and sharpness of the ink layer of the imprint, especially for small images, and even changes the tone value and color of the dot. When the product requires a thick ink layer and thick lines, the plate film should be thicker accordingly. Normally, the thickness of the plate film most conducive to ink transfer is: screen thickness + 6μm ~ 8μm. The film thickness can be measured with a film thickness meter.

　　 (2), Demoulding property of printing plate of flat screen printing machine

　　Releasability refers to the difficulty of removing the plate film from the screen of the printing plate. After the plate-making fails or the printing task is completed, in order to regenerate the screen, demolding is required. The demoulding operation should be simple, economical, and with minimal damage to the wire mesh.

The above is the quality requirements of the flat screen printing machine plates brought by the licheng Flat Screen Printing Machine Factory. The performance indicators of the flat screen printing machine plates can be expressed as: the reproducibility of the flat screen printing machine plates, the printing panel The thickness of the film, the durability of the printing plate of the flat screen printing machine, and the release property of the printing plate of the flat screen printing machine. You can understand the factors that affect the quality of screen printing we mentioned last time.
