QT4-24 Semi Automatic Block Making Machine Production Line Operation Process Standard Control Steps

The whole production line of QT4-24 adopts semi-automatic operation, and the whole forming cycle of a single batch of blocks is 24-30 seconds. The standard operation process is as follows:

• Pallet Placement: Put the empty pallet on the designated position of the host machine, align it with the lower mold, and ensure that the pallet is flat and without deviation.
• Lower Mould Falling: Press the Mould Down button of the host machine, make the lower mold fall on the pallet, release the button, and the lower mold stops falling.
• Upper Mould Retraction: Press the Upper Mould Back button, move the upper mold to the side of the host machine, and reserve the feeding space.
• 
• Raw Material Mixing & Conveying: Start the mixer, mix the cement, sand and other raw materials according to the ratio; after mixing, start the belt conveyor, and convey the mixed raw materials to the hopper of the host machine.
• Host Machine Feeding: Press the Put Material button of the host machine, put the raw materials from the hopper into the lower mold, and control the feeding amount according to the block size.
• 
• Vibration Forming: Press the Start (Vibration) button, start the vibration box of the host machine, and vibrate the raw materials in the lower mold to make the concrete dense and formed. The vibration time is adjusted according to the block type (generally 10-20 seconds).
• Upper Mould Reset: Press the Upper Mould On button, pull the upper mold back to the top of the lower mold, the firing pin collides, the fixed mold pin is separated from the fixed mold hole, and the upper mold falls into the lower mold for pressing.
• Vibration Termination: After the pressing and forming are completed, press the Pause button to stop the vibration of the host machine.
• 
• Upper Mould Lifting: Press the Mould Up button, lift the upper mold, the fixed mold pin inserts into the pin hole, the upper mold is suspended in the air, and the concrete block is formed.
• Brick Transportation: Use the brick trolley to transport the formed block (with pallet) to the curing area for natural curing, and then repeat the above steps for the next cycle of production.
• 

Operation Key Points

• Feeding Control: The feeding amount should be moderate, too much will cause block overflow, too little will cause incomplete block forming and low strength.
• Vibration Time: The vibration time should be adjusted according to the raw material moisture content and block type. The moisture content is high, the vibration time is short; the moisture content is low, the vibration time is appropriately extended.
• Equipment Cooperation: The start and stop of the mixer and conveyor should be matched with the host machine feeding to avoid raw material accumulation or shortage.
• Continuous Production: After the formal production, the continuous operation of the production line is recommended to improve production efficiency, and the interval between each cycle should not exceed 1 minute.

Curing Suggestion

The formed concrete blocks are cured naturally in the curing area for 7-14 days (the specific time is determined according to the local temperature and humidity in developing countries). During curing, the blocks should be watered regularly to avoid cracking due to dryness, and the cured blocks can be put into use after reaching the strength standard.
