Downward Press Type Brick Cutter
(Technical Description and Working Principle)
1. Overview
The Downward Press Type Brick Cutter is a specialized machine designed for cutting extruded clay columns into individual green bricks with high precision. It uses a vertical downward cutting mechanism, where cutting wires or blades descend from above to achieve straight and clean cuts. This system ensures accurate dimensions and smooth surfaces, making it an essential component in modern automatic brick production lines.
2. Structure and Components
(1) Cutting Frame: Holds multiple cutting wires or blades arranged for precise spacing.
(2) Guide Rail: Ensures vertical alignment during the downward cutting process.
(3) Drive Mechanism: Motor-driven system (gear, crank, or servo) for smooth downward movement.
(4) Cutting Wires: High-tensile wires for clean and accurate cuts.
(5) Control System: PLC-based automation with optical sensors for length detection.
(6) Conveyor: Transfers the extruded clay column to the cutting zone.
(7) Safety Devices: Emergency stop switch, protective covers.
3. Working Principle
(1) Extrusion: The vacuum extruder continuously extrudes clay columns.
(2) Length Detection: Optical sensors or limit switches detect the required length.
(3) Downward Cutting: The cutting frame with wires moves vertically downward, cutting the entire row simultaneously.
(4) Reset: The frame returns to the top, and the cycle repeats.
(5) Automation: The process is synchronized with the extruder and the robotic setting machine.
4. Technical Advantages:
Feature | Benefits |
