Interlock Bricks Manufacturing Machine Structure & Characteristics

Interlock brick manufacturing machines achieve efficient production through modular structural design. The bricks they produce play an important role in municipal administration, water conservancy, ecology and other fields due to the mechanical advantages and diverse functions of the interlocking structure.

1. Structure of interlocking brick manufacturing machines
The structural design of interlocking brick manufacturing machines must meet the needs of brick forming, demoulding and automated production. Its core components are as follows:
(1). Main frame system
- Frame structure: Made of high-strength steel welded or bolted to ensure the stability of the equipment during operation, usually equipped with shock absorbers to reduce vibration.
- Guide system: Guide the mold up and down through guide rails, guide columns and other components to ensure molding accuracy.
(2). Mold system
- Upper mold and lower mold:
- Upper mold: Contains the molding cavity that presses the top surface of the brick. The specific shape (such as mortise and tenon structure, slot, etc.) can be designed according to the texture and concave and convex structure of the interlocking brick.
- Lower mold: used to form the bottom and side contours of the brick. Some molds need to reserve drainage holes or anti-slip patterns.
- Mold replacement device: supports the rapid replacement of molds of different specifications to adapt to the production of interlocking bricks of different sizes and shapes.
(3). Hydraulic system
- Hydraulic pump station: provides the power required to press bricks, and pushes the upper mold down through the hydraulic cylinder to ensure uniform density of bricks.
- Pressure regulating device: can adjust the pressing pressure according to the characteristics of raw materials (such as concrete, fly ash, sand and gravel, etc.) to ensure the strength of bricks.
(4). Feeding and distribution system
- Storage hopper: stores the mixed concrete or other raw materials.
- Feeding mechanism: the raw materials are evenly transported to the mold through belts, screw conveyors, etc., and some equipment is equipped with quantitative distribution devices to control the thickness of bricks.
(5). Demolding and brick discharging system
- Demolding mechanism: the formed bricks are ejected from the mold by hydraulic or mechanical means to avoid damage to the brick body.
- Brick conveyor belt: transports demoulding bricks to the curing area. Some equipment is equipped with a stacking device to realize automatic stacking.
(6). Control system
- PLC control system: integrated touch screen human-machine interface, can set production parameters (such as pressing time, pressure, feeding amount, etc.), monitor equipment operation status.
- Sensors and safety devices: including pressure sensors, position sensors, etc., to ensure the safety of the production process (such as overload protection, mold in place detection).

2. Characteristics of interlocking brick manufacturing machines
The design of interlocking brick making machines revolves around "high efficiency, precision, and multi-function", and its core features are as follows:
(1). Production efficiency and automation
- High degree of automation, can realize continuous operation of the entire process of feeding, pressing, demoulding, and bricking, and the average daily output of a single device can reach thousands to tens of thousands of pieces.
- Some high-end models support multi-mold parallel production to improve production capacity.
(2). Molding accuracy and brick quality
- The mold has high precision and stable pressing pressure, which can ensure the dimensional tolerance (such as length and width error ≤1mm) and strength (compressive strength can reach 20-50MPa) of interlocking bricks.
- The surface of the brick is flat, and the interlocking structure (such as male and female grooves, raised grooves) is tightly engaged, which improves the integrity after laying.
(3). Raw material adaptability and environmental protection
- A variety of raw materials can be used: such as cement, sand, stone, fly ash, construction waste, etc. Some equipment supports the use of recycled aggregates, which reduces costs and meets environmental protection requirements.
- The production process is low-noise and low-dust (dust removal equipment is required), which meets industrial environmental protection standards.
(4). Flexibility and versatility
- It supports the customization of interlocking bricks of different specifications (such as side length 100-300mm, thickness 50-200mm), and is suitable for square bricks, slope protection bricks, grass planting bricks and other types.
- Some machines can produce ordinary bricks or other concrete products by replacing molds to improve equipment utilization.
(5). Maintenance and operation convenience
- The modular design facilitates the replacement and maintenance of parts, and the hydraulic system and electrical system are reasonably laid out, reducing the difficulty of troubleshooting.
- The operation interface is user-friendly, and novices can take up their posts after a short training.

3. Application scenarios of interlocking bricks
Due to their unique structure and superior performance, interlocking bricks are widely used in the following fields:
(1). Municipal and garden engineering
- Road paving: urban sidewalks, pedestrian streets, park trails, etc., using interlocking structures to enhance the road surface's ability to resist deformation and adapt to pedestrian and light vehicle loads.
- Squares and parking lots: municipal squares, commercial parking lots, etc., the bite between bricks can reduce settlement, and the surface texture provides anti-slip function.
- Garden landscape: courtyard trails, landscape platforms, some interlocking bricks can be matched with grass planting hole design to achieve ecological paving (such as grass planting bricks).
(2). Water conservancy and slope engineering
- River slope protection: The slope protection of rivers and lakes, interlocking bricks are interlocked to form a whole, resisting water erosion, and vegetation can be planted to stabilize the slope.
- Dam and flood control engineering: heavy interlocking bricks (such as concrete blocks) are used to pave the surface of the dam to enhance the ability to resist wind and wave impact.
(3). Transportation engineering
- Temporary roads and construction access roads: construction sites, mine transportation roads, etc., can quickly lay interlocking bricks, which are easy to reuse and disassemble.
- Airport and dock ground: Some high-strength interlocking bricks can be used for small airport runways and dock yards to meet heavy load requirements.
(4). Ecological and environmental protection engineering
- Rainwater gardens and sponge cities: Permeable interlocking bricks (with pore structures) can promote rainwater infiltration, reduce urban waterlogging, and replenish groundwater.
- Saline-alkali land improvement: After laying some interlocking bricks, the saline-alkali layer can be isolated, and the soil environment can be improved with vegetation planting.
(5). Architecture and Home Furnishing
- Courtyard and terrace paving: villa courtyards, roof terraces, etc., improve aesthetics through the various shapes of interlocking bricks (such as imitation stone and imitation wood textures).
- Fences and retaining walls: small interlocking bricks can be used to build landscape walls or light retaining walls, with stable structure and convenient construction.
