Since the Spring Festival, with the development of a new coronavirus-infected pneumonia epidemic, masks have become a key concern of the people throughout  China. It has entered a stage of wearing masks for all people, and the state is actively supporting the resumption and production of mask companies.

“Although we can’t be on the front line like medical staff, we can fully support the rear supply to ensure the supply of materials.” Based on the application of PI130 series inverters in mask machines and other fields, POWTRAN is the key automation equipment for the production of protective materials provides mature solutions, and actively contributes to the fight against the epidemic.


1.Mask machine introduction

The mask machine is to make various masks with certain filtering performance through processes such as hot pressing, folding molding, ultrasonic welding, scrap removal, welding of ear bands and nose bridge strips, etc. The mask equipment is not a single machine, it requires The cooperation of multiple machines completes various processes. Our common non-woven flat (common medical mask) mask machine has a production efficiency of about 120-150PCS / MIN.


2.Mask production process

Production process of disposable medical masks:

(1). Selection of raw materials: Choose appropriate amount of PP non-woven fabric, nose bridge strip, silk thread, antibacterial filter paper, activated carbon cloth, waterproof breathable membrane, non-woven edging material and ear band.

(2). Production of tablets: Hang PP non-woven fabric raw materials, anti-bacterial filter paper, activated carbon cloth and waterproof breathable membrane on the mask sheeter's material rack, and debug the machine to produce automatically.

(3). Welding synthetic type: Place the nose bridge strip over the mask sheet, and then fold the mask sheet and wrap the nose bridge strip.

(4). Inner workshop: sterilize the masks and vacuum seal them.

(5). Outsourced shipment: centrally integrate packaged masks into external packaging shipments.


3.Full automatic mask production line + inverter application program

(1). Inverter stepless speed regulation, one-time welding and forming, anti-wear, and power increaser in the chassis;

(2). Fully-automatic integrated production, which only needs 1-2 people to operate. The frequency conversion speed regulation method uses a keyboard potentiometer;

(3). High-speed production with a production capacity of 80-100PCS / MIN and more than 100,000-140,000 masks per day;

(4). The qualified rate of production through frequency conversion speed regulation equipment is as high as 99%.


4.Application in Guangdong province


Our customers in Guangdong chose the PI130 series inverter on the spot, which is applied to the transmission shaft of the production line. The motor power is 0.75kW and the three-phase 220V voltage level. During the debugging process, the inverter runs stably, and the low-frequency output torque is large. The customer is very satisfied, and a batch order notification is immediately issued.

When this batch of orders was placed, during the severe epidemic situation and lack of supplies, in order to meet the customer's needs as soon as possible, the company actively deployed the resources of all parties and urgently mobilized the product to cooperate with the support. After multiple efforts, the delivery was successfully completed.
