เครื่องผสมสารประกอบโฟมความเร็วสูง High Speed Mixer

The High Speed Mixer is useful rapid mixing of foam compounds to produce a well-mixed sample pat. This is to form a sample for testing purposes as well as quality control.  It is made from Stainless Steel. Thus, it assists easy cleaning and avoids corrosion. Featuring automated mixing as well as variable mixing speeds for added ease of use.

The mixer has three mixing times and three different testing speeds.  Thus, it enables 9 combinations. Any of these combinations create a sample pat which is entered onto the PLC once values are set on the PLC. A hand controller initiates the test enabling the production of sample pat. This is according to set curing times.

High Speed Mixer Apparatus

The High Speed Mixer is made from Stainless Steel for corrosion protection and for ease of cleaning. The mixing shaft is driven by servo motor to maintain constant torque, and to produce high RPM. The High Speed Mixer has been programmed to reach 2000 RPM; however, this can reach 2400 RPM if programmed.

Pneumatic cylinders are used to clamp the cup in position for mixing. A two hand control pendant is used to operate the machine, and digital timers are used to measure product curing times.

A PLC controller is used to set the speeds and run times.

Optional Items

Procedure

• Turn ON the Power isolator switch (located on the right hand side of the electrical cabinet).

• Wait 20 seconds for the drives to initiate. When Step 1 is displayed on the top left corner of the PLC display, then the machine is ready to operate.

• Set the RPMs and mixing times for each Event on the PLC controller. The labels indicate:

• S1: Speed 1
• S2: Speed 2
• S3: Speed 3
• T1: Time 1
• T2: Time 2
• T3: Time 3

Press the appropriate area on the touch screen to adjust the variable speed or time. Enter in the required value using the numbered keypad. Press the Enter button to store the values.

• Weigh and pour chemicals into the cup for the first mixing event.

• Place the chemical cup securely into the clamp plate. Ensure that it is all the way back into the U-shape groove

• Simultaneously press both operating buttons on the two-hand control pendant, and hold until the cup has fully retracted against the upper sealing face. This will initiate the first mixing event. The cup will be confirmed to be in position by two plunger switches pressing against the cup flange. If the cup is not in place, then the process will not continue.
