MX Gun Assembly

 

General

The MZ Gun series are swirl/spray and are used in labeling and non woven applications. The MZ Guns are “air open and spring closed” and use the CF-200 style gun module. These applicators can be used with general packaging grade and PSA Pressure sensitive adhesives at temperatures from 93°C(200°F) up to 190°C(375°F). 

The MZ Guns require 2 valve signals for proper application. One signal operates the valve activation of the fluid module and the other signal operates the swirl air which enters through the gun below the fluid port. These guns have an air heating grid machined into the bottom of the gun that supplies heated air for the swirl activation. This helps ensure that the swirl pattern is accurately placed and helps control the stringing or “angel hair” that is commonly produced with spray/swirl applications. The MZ Guns can be configured in various spacing configurations for any required application.

Electrical

Each ME Gun is configured with a 220-240VAC heater cartridge. The wattages vary depending on the size of each manifold. The standard heater OD is ½”.  

Mounting

 The MZ Guns come standard with a clamp for ½” round bar or hex bar stock. There are 3/8”round bar bracket clamps available and can be purchased separately. If additional brackets are required, please request as additional item.

Air Activation

They require compressed air at a pressure of at least 60PSI to lift the needle off of the seat which allows the adhesive to flow through the valve and onto the product. Gun configurations having 4 or more modules will require greater a higher volume of air as well as a higher pressure base no less than 80PSI. For any applicator with more than 4 modules, it’s recommended that 3/8” or 10mm air line is used to supply the compressed air. All air ports are 1/8” NPT. The MZ Guns also offer various activation configurations for independent air porting. Most independent air configurations come with QD fittings to allow for easy installation

 

 

 

Hoses

All MZ Guns require special hoses that contain a ¼” air tube inside the hose that helps heat the air that is required for the swirl activation.

Solenoid

Most MZ Guns do not come with solenoids and must be ordered separately. Each MZ gun will require regulated air to both solenoids. Make sure to include 2 solenoids and 2 air regulators for each MZ Gun being installed. If multiple MZ Guns are being used, you can split the air from each regulator to operate multiple swirl modules and swirl air control. The solenoids are 24VDC and can be fired from any PLC and/or most existing pattern controls.  

Air Activation

The MX electric valve is fired from a special control or valve driver. This driver can be purchased as a separate individual box that receives a 24VDC signal from a PLC or other controller and outputs a signal to the MX. If you are using or have the Valco MCS, MCP-4, VCX, or MCP-25 control this driver is already built into the software and can be operated without the use of the external driver.
