Application scheme of servo drive in automatic mask machine

With the surge in the supply of mask machines, the matching N95 mask machine stepper motor and servo drive are also rising a lot, and the stepper motor has long been widely used in the field of mask machine, and there is a very complete technical application implementation plan!

Servo motor original genuine – AC servo drive controller – Application scheme of servo drive in automatic mask machine

There are many types of mask machine models and specifications on the market, and stepper motor manufacturers have summarized them as follows:

Mask machine equipment type: cup mask machine, non-woven flat mask machine, N95 mask machine, 3M9001/9002 folding mask machine, duckbill mask machine, three-dimensional 3M dust mask machine, etc.

According to the welding method and operation method of the ear strap of the flat mask machine series products, it can be divided into:

The production of these three flat masks must use the mask body, which is an indispensable part of the composition of flat masks.

Production efficiency:

Flat mask punching machine 120-150 pieces per minute, ear strap automatic welding machine 40-50 pieces. Among the production line equipment, the most important is the mask flake machine (also known as the mask all-in-one machine), and according to the shape and material of the mask produced, there are mainly 3 types.

Mask equipment is not a machine equipment, it requires several machines and equipment to cooperate with each other for a variety of different processes, mask production process is the multi-layer non-woven fabric through hot pressing, folding molding, ultrasonic welding, waste removal, ear straps nose bridge welding and other processes to produce a variety of masks with corresponding filtering performance.

Mask machine stepper motor with drive

Model: DM545A

Name: Low voltage two-phase DM545A

Introduction: DM545A type driver, with lower motor heating, running noise and higher stability, as well as lower cost, mainly drives 42, 57 two-phase hybrid stepper motor. There are 15 kinds of microstep subdivisions, and the maximum number of steps is 25000Pulse/rev; Its operating peak current range is 1A-4.2A, the output current has a total of 8 levels, the resolution of the current is about 0.45A, and it has the functions of automatic half-current, overvoltage and overcurrent protection.

This driver is DC power supply, the recommended operating voltage range is 24VDC-36VDC, the voltage does not exceed 50VDC, not less than 20VDC

Drive capabilities

Operating instructions

Microstep subdivision settings

The SW5-SW8 four DIP switches set the number of driver microstep subdivisions, which has a total of 15 microstep subdivisions. When the user sets up a microstep subdivision, the drive should be stopped first. For the specific number of microstep subdivisions, please refer to the driver layout.

Output subdivision settings

The driver output current is set by SW1-SW3 three DIP switches, and its output current has a total of 8 levels. For specific output current settings, please refer to the driver layout.

AC servo drive controller

Automatic half-flow function

The SW4 allows the user to set the automatic half-flow function of the drive. OFF means that the quiescent current is set to half of the dynamic current, and on means that the quiescent current is the same as the dynamic current. In general use, SW4 should be set to off, so that the heat generated by the motor and drive is reduced and the reliability is improved. After the pulse train stops, the current is automatically reduced to about half (60% of the actual value) in about 0.4 seconds, and the heat generation is theoretically reduced to 36%.

Signal interface

PUL+ and PUL- are the positive and negative terminals of the control pulse signal; DIR+ and DIR- are the positive and negative terminals of the directional signal; ENA+ and ENA- are the positive and negative terminals of the enable signal.

Motor interface

A+ and A- connected stepper motor A-phase windings positive and negative terminals; B+ and B- connect the positive and negative ends of the B-phase windings of the stepper motor. When the A and B two-phase windings are exchanged, the motor direction can be reversed.

Power connector

It adopts DC power supply, the working voltage range is recommended to be 20-40VDC, and the power supply power is greater than 100W.

Light

The drive has two LEDs, red and green. Among them, the green light is the power indicator, and the green light is always on when the drive is powered on; The red light is a fault indicator, and when there is an overvoltage and overcurrent fault, the fault light is always on. After the fault clears, the red light goes off. When a drive fails, only power-on and re-enable clears the fault.

Installation instructions

The dimensions of the drive are: 118×75.5×34mm, and the mounting hole distance is 112mmmm. Both horizontal and vertical installation is possible, vertical installation is recommended. When installing, it should be placed snugly against the metal cabinet to facilitate heat dissipation.

Model: 57mm

Name:57mm three-phase hybrid stepper motor

Introduction: 57mm series three-phase hybrid stepper motor, based on the industry’s advanced magnetic circuit design scheme. In terms of material selection, it is made of high-temperature resistant permanent magnets and high-quality cold-rolled steel sheets, Japanese NMB or NSK bearings are selected, and the surface of the motor is sprayed or sealed with aluminum shell.
