The production of grass and stone isolation strips (mainly made of mainstream plastic materials) involves three major processes: "raw material processing → melt shaping → subsequent processing." The core function of the corresponding equipment is to transform plastic granules such as PVC, HDPE, and PE into isolation strip products in rolls and sheets that meet specific specifications.
Hopper and Feeding System: Stores plastic granules and evenly feeds them to the barrel via an automatic feeder, preventing raw material accumulation and uneven melting.
Barrel and Screw: The barrel is heated by electric heating coils (temperature adjusted according to material: PVC requires 160-190℃, HDPE requires 180-220℃). The high-speed rotating screw extrudes and shears the raw material to a molten state and pushes it to the mold.
Molding Die: Customized according to the isolation strip specifications (e.g., width 5-20cm, thickness 2-5mm). After the molten plastic passes through the mold, the initial product outline is formed. The mold precision directly affects the flatness of the isolation strip's cross-section.
Cooling and Traction System: A cold water tank rapidly cools the formed isolation strip (preventing deformation). A traction machine pulls the product at a stable speed, ensuring uniform length and no tensile deformation.
Grass and stone isolation belt equipment (including manufacturing equipment and on-site construction equipment) is the core guarantee supporting the "efficient production" and "easy implementation" of isolation belts. Its design revolves around two core objectives: "adapting to the characteristics of plastic processing" and "simplifying the greening construction process," resulting in unique functional characteristics and application advantages. Grass and stone isolation belt production uses plastic materials (PVC, HDPE, PE) as the core raw material. The production equipment needs to meet the requirements of "precise melt molding, efficient processing, and diversified product adaptability," and its characteristics and advantages are highly suitable for mass production scenarios. Mainstream production equipment (such as fully automatic extrusion production lines) can integrate multiple processes such as "raw material feeding → melt extrusion → cooling and shaping → punching → cutting," eliminating the need for frequent manual transfer of semi-finished products and forming a continuous production process. For example, in an HDPE isolation belt production line, after plastic granules enter from the hopper, they are shaped by the extruder, cooled in a cold water tank, and directly enter a CNC punching machine to process drainage holes. Finally, they are rolled by a cutting machine, with the entire process automated, reducing intermediate losses.
Reduced maintenance costs and lower labor burden: Traditional greening barriers rely on manual pruning, ridging, or brick and stone paving, which is not only time-consuming and labor-intensive, but also easily damaged by rain and root growth. Grass and stone barriers, once installed, can prevent plant root spread and soil mixing for a long time, significantly reducing the labor costs of pruning, weeding, and boundary re-maintenance. They are especially suitable for large-scale municipal greening, parks, or factory landscaping.
Convenient installation and high construction efficiency, Grass and stone barriers require no complicated construction processes:
1.Low foundation requirements: Only leveling the soil in the area to be separated is needed; no concrete pouring or deep trench digging is required.
2.Simple operation: Roll materials can be directly unfolded and laid; board materials are spliced using clips. A single person can complete small-area construction, and large-area projects can be quickly advanced, shortening the construction period of greening projects.
3.Aesthetically pleasing and unified, enhancing landscape harmony: Grass and stone barriers are mostly in understated colors such as black and green, blending into the green environment without disrupting the overall aesthetic appeal. Some products can also be combined with decorative designs (such as imitation stone textures and invisible splicing seams), ensuring functionality while enhancing the refinement of details. Compared to the harshness of brick and stone dividers, plastic dividers offer a softer feel and harmonize better with the natural texture of lawns and flowers.
Environmentally Friendly: High-quality grass-stone dividers (such as HDPE) are recyclable and do not release toxic substances during use, posing no harm to soil or plants.
Durable: They typically last 5-10 years (HDPE can last 8-10 years), far exceeding traditional wooden or simple plastic dividers, resulting in lower long-term costs.
Lightweight and Easy to Transport: The lightweight plastic material eliminates the risk of damage during transport, reducing logistics costs compared to dividers made of brick, stone, or metal.
Aids Drainage and Protects Vegetation Growth: Grass-stone dividers are designed with pre-drainage holes or gaps to guide water out of the soil during heavy rains, preventing root rot in lawns or flowers. Simultaneously, the height of the divider (usually 10-20cm) helps prevent surface runoff from eroding the soil, protecting plant roots and indirectly improving the survival rate of greenery.
