The introduction of mask machine accessories

Firstly, Introduction of mask machine accessories

The mask machine is to make various masks with certain filtering performance through the processes of hot pressing, folding forming, ultrasonic welding, waste removal, ear belt and nose strip welding. The mask equipment is not a single machine, it needs The cooperation of multiple machines completes various processes.

The accessories on the mask machine can be divided into: magnetic powder clutch brake, inflatable shaft, correction integrated machine, reducer, gear, safety chuck and other related accessories.




Secondly, the scope of application of mask machine gear

It is widely used in various fields such as mask body machine, filming machine, one-to-two, three-dimensional mask machine and cup-shaped mask machine.

Mask machine accessories production process:

1. First of all, it is necessary to design and confirm the drawings of the accessories, so as to select high-quality materials for processing.

2. Afterwards, prepare the materials for heat treatment, and adopt 16MnCr5 normalizing 42Cr (SCM420) quenching and tempering.

3. At this time, fine turning should be carried out to process the outer end surface of the inner hole. At the same time, it should be ensured that the gear hobbing guarantees the tooth profile, tooth radial run out, tooth pitch deviation, tooth surface smoothness, etc.

4. At the same time, it needs to be milled, mainly including hole milling, keyway milling, edge extrusion, deburring, and key pulling, and then it needs to be subjected to secondary heat treatment, 16MnCr5 overall carburizing, 42Cr (SCM420) high frequency quenching, hardness HRC50 -62.

5. The internal and external circular grinding of the gear is required, mainly for grinding the inner hole, grinding the outer circle, grinding the end surface, etc., grinding the surface, then hard scraping the tooth, the tooth surface hard scraping (small modulus), tooth surface grinding (large mold) Number) etc.

6. After the above process is completed, the quality inspection can be carried out to ensure accuracy and quality. Engraving and marking, packaging and warehousing can be carried out under the condition of ensuring that the product is correct.

Fourthly, mask machine accessories maintenance

1. The power supply for the accessories of the automatic willow-type automatic mask machine is 220V, 50/60HZ, 1phase. When connecting to the power, check whether the power supply voltage is consistent and stable. Only when the power supply is consistent and stable can the power supply be connected. Otherwise, the power system and ultrasonic will be easily damaged The occurrence of systems and accidents.

2. The mask machine must be well grounded at all times to avoid leakage of electricity and injury.

3. When the weather is dry or the temperature is low, some parts of the mask machine may be electrostatically charged due to the friction of the raw materials. Please pay attention to protection.

4. All adjustments and maintenance of electrical and mechanical parts must be assigned to a special person, and non-professionals are not allowed to tamper with it. The machine must be shut down when loading materials, adjusting parts, checking or repairing the machine. The electrical part must be cut off during maintenance.

5. Non-professionals or maintenance personnel should not open the electric box and ultrasonic system of the mask machine.

6. The air pressure of the mask machine is required to be around 0.5P0.6P. Please do not work in the range below and above the air pressure.

7. During the operation of the mask machine, please do not touch the electrical components, such as: ultrasonic electric box, vibrator (with high voltage, please discharge first when disassembling), welding head, etc.

8. When the mask machine is running, please do not touch the moving mechanical parts, blades, scissors parts, air cylinders, etc. to avoid accidents.

9. After replacing the accessories of the ultrasonic system, the mask machine must first detect and adjust the ultrasonic frequency before it can be turned on. Otherwise, the ultrasonic system and welding head will be damaged.

10. Check the tightness of belts and chains once a week. The lubricating oil should be changed regularly for parts such as chain sprocket.

11. The order of starting up every day is: check the air source and equipment condition, then turn on the main power, followed by the ultrasonic system. When shutting down, turn off the ultrasonic system first and then turn off the main power.

12. The reducer of the mask machine needs to be replaced with new lubricating oil every 1000 hours of operation.

13. When the mask machine is not running for a long time, please apply anti-rust oil to the rust-prone parts.
