Overall performance and assembly quality requirements of liquid sanitary napkin machinery

Through the analysis of the mechanical performance, marking, packaging, transportation and storage of liquid sanitary napkin, we can better know the comprehensiveness of its function and quality.

1. Quality requirements for processing and assembly of liquid sanitary napkin machinery

  • All parts of the liquid sanitary napkin machine shall pass the inspection, and the purchased and external accessories shall meet the requirements of corresponding standards. They can be assembled only after passing the verification.
  • Ensure that the quality of the melt adhesive shall meet the corresponding standards, and the imported equipment shall have corresponding quality assurance materials and maintenance service commitments.
  • No surface delamination treatment, uniform surface treatment, discoloration and other defects.
  • The surface of die wheel and anti sticking material shall be flat and smooth without delamination, obvious depression and other defects.
  • There shall be no obvious clamping phenomenon at all connecting parts and unloading mechanism.
  • The installation and indication of each indicator shall be accurate, sensitive and reliable.
  • Flexible equipment, no block
  • The radial circular runout of the outer cylindrical surface of the transition roll, drive roll and inflatable shaft roll shall not be greater than 05mm.
  • Other supporting parts of liquid sanitary napkin machinery shall meet the requirements of corresponding standards.

 

Safety performance requirements
  • The exposed rotating parts of liquid sanitary napkin mechanical equipment shall be equipped with safety protection devices.
  • The installation and protective equipment shall comply with the provisions of 1. Electrical equipment shall have reliable grounding terminals and obvious grounding marks.
  • The button shall be sensitive, reliable and correct.
  • The insulation resistance between the power circuit conductor and the protective grounding circuit shall not be less than 1ms.
  • The AC between the circuit and the protective grounding circuit shall be 50Hz. The rated power supply voltage of electrical equipment is 2 times or 1000V, and the voltage withstand test shall not flicker, arcing or breakdown.
  • The liquid sanitary napkin equipment shall be equipped with emergency stop control and interlocking protection devices and work normally.
  • When the mechanism recovers power supply due to operation failure or after operation, it shall not act on its own.
  • The production line shall set similar warning signs on the machines that may cause damage, and set warning signs for electric shock on the door of the electric control cabinet.

 

2. Overall performance of liquid sanitary napkin machinery

  • It is allowed to produce g / t939-2018.
  • The noise level of the machine should not be greater than 85dB (level a).
  • During no-load operation, all parts of the transmission system shall be well lubricated without oil leakage: the synchronous belt shall be tensioned without slipping.
  • The liquid sanitary napkin machine operates continuously at the maximum production speed for 80% to 4 hours at 4 degrees. The action of safety devices of each system is coordinated, sensitive and stable, the operation of the whole machine is stable, and all safety protection devices are firm and reliable.

 

3. Marking, packaging, transportation and storage of liquid sanitary napkin machinery

 

sign

The mechanical mark of liquid sanitary napkin shall be fixed at the position where the equipment is obvious and not easy to be damaged. Its type, size and technical requirements shall comply with the relevant provisions of GB / t1306, and the equipment mark shall include the following contents:

Equipment name and model; Standard code of main technical parameters and equipment; Name, address, manufacturing date and product number of the manufacturer.

 

packing

(1) The mechanical packaging of liquid sanitary napkins shall comply with QB / t1588 5. The packaging mark shall comply with the provisions of GB / T191 to ensure that it will not be damaged during normal transportation.

(2) Electrical components or parts shall be moisture-proof and shockproof.

(3) When the equipment leaves the factory, the accompanying spare parts and tools shall be provided.

 

Transportation and storage

(1) Liquid sanitary napkin equipment can be transported by any means, but it shall not be damaged by rain, packing box and violent vibration during transportation.

(2) The room shall be ventilated to avoid the presence of moisture and other corrosive substances.

 

To sum up, the liquid sanitary napkin machine must meet the standards before it can be used normally.
