ALVA 4-ft log rounding machine is a dedicated pre-rounding equipment customized for logs of 1.22m specification. It accurately meets the raw material processing needs of small and medium-sized plywood and veneer production lines, and is widely applicable to the industrial processing of common wood species such as poplar, pine, and eucalyptus, providing high-standard base material guarantee for the subsequent peeling process.

The equipment adopts an exclusive structural design of "double-roller counter-pressure + center positioning". Aiming at the characteristic that 4-foot short logs are prone to deviation, it optimizes the roller group spacing adjustment mechanism and feeding guide device. Through the dual control of mechanical limit and hydraulic buffer, it ensures that the log always maintains center stability during the rounding process, effectively avoiding the end damage problem during short material processing. The machine body adopts a modular splicing process, and the core rounding mechanism and auxiliary support components can be quickly disassembled for maintenance, which is suitable for the equipment layout and maintenance space requirements of small and medium-sized workshops.

 01 

4-Ft Custom Configuration for Precise Rounding of Small-Spec Logs

Equipped with a narrow-width precision toothed roller set tailored for 4-foot logs, the roller tooth spacing and meshing angle are optimized for short logs. It enables more snug roller pressing and rounding of small-diameter and short logs, avoiding issues such as deviation and uneven stress that narrow materials encounter in wide-width equipment, resulting in stronger consistency of the rounded base material.

 03 

Low-Cost Operation and Maintenance Solution for Small and Medium Capacity Scenarios

The electric control system adopts a streamlined modular configuration exclusive to 4-foot production lines, with functions tailored to small and medium capacity needs, leading to lower later maintenance costs. Vulnerable parts (such as roller teeth and seals) adopt universal specifications, reducing the procurement and replacement costs by 40% compared with custom parts, which is suitable for the cost control needs of small and medium-batch production.

 05 

Compact Body Design for Small and Medium-Sized Production Lines/Sites

The machine body adopts an exclusive compact layout for 4-foot specifications, reducing the floor space by 30% compared with conventional rounding machines while retaining complete functional modules. It can be flexibly integrated into small and medium-sized veneer peeling production lines or adapted to processing scenarios with limited factory space, balancing efficiency and site compatibility.

/ Product characteristic /

• 1. Enlarged Roller Design for Doubled Peeling Efficiency

• The hydraulic veneer peeling machine adopts a core roller with an enlarged diameter, which directly increases the linear speed of log peeling and breaks through the efficiency bottleneck of traditional small-sized rollers. This structural optimization shortens the processing cycle of a single log and significantly improves the overall output of veneer production.

• 
  

• 2. Chrome-Plated Grooved Roller with Dual Advantages of Wear Resistance and Anti-Adhesion

• 
  

• The roller surface is treated with hard chrome plating, which enhances its wear resistance several times compared to ordinary rollers. Meanwhile, the integrated groove design on the roller surface can effectively prevent bark adhesion during the peeling process. These dual characteristics reduce the downtime for equipment cleaning and maintenance, and extend the service life of core components.

• 
  

• 3. Well-Designed Structure + High-Quality Material Selection for Stable and Reliable Quality

• 
  

• All mechanical components have undergone multiple rounds of structural optimization design and are made of high-grade alloy steel and precision castings. Strict quality control is implemented throughout the process from raw material selection to production and assembly, ensuring the equipment maintains stable performance during long-term continuous operation and reducing the risk of unplanned downtime.

• 
  

• 4. Intelligent Hydraulic Feeding for Adaptive Compatibility with Various Logs

• 
  

• The hydraulically driven feeding system provides strong and stable log propelling force, supporting stepless speed regulation and precise adjustment of clamping force. It can seamlessly adapt to logs of different diameters, hardness levels and wood species (such as eucalyptus, pine, poplar, etc.) without frequent mechanical parameter adjustments.

• 
  

• 5. Self-Reset Reversing Switch for Safe and Convenient Operation

• 
  

• The ergonomically designed self-reset manual reversing switch has a fast response and anti-misoperation function. When there is an abnormality in log feeding, operators can quickly reverse the machine, which not only simplifies the operation process but also effectively avoids equipment damage and personal safety hazards.

• 
  

• 6. Double-End Feeding + Efficient Lubrication for Smooth and Efficient Operation

• 
  

• The front-and-rear bidirectional feeding mechanism enables efficient log infeed and outfeed, which perfectly matches the high-speed peeling rhythm of the core roller. Equipped with a large-displacement oil pump, it provides constant-pressure lubrication for the moving parts of the feeding system, ensuring the equipment operates smoothly even under harsh working conditions and reducing mechanical wear.

• 
  

• 7. Heavy-Duty Frame + High-Quality Bearings for Longer Service Life

• 
  

• The main frame is integrally welded with thick-walled structural steel and undergoes annealing stress relief treatment, ensuring a stable and impact-resistant structure. The key rotating components are equipped with imported precision bearings, which have excellent wear resistance and damage resistance. The overall durability is far superior to traditional models, with the service life extended by more than 50% in industrial scenarios.
