The frame assembly adopts a box-type structural design, and is fabricated with thick steel plates through welding. The surface is treated with sand blasting for rust removal and spraying, delivering good impact resistance and corrosion resistance. Anchor bolt mounting holes are reserved at the bottom of the frame. Operators can calibrate the installation level of the equipment with a level gauge to reduce vibration and displacement during operation. The interior of the frame is reserved with installation space for saw blades, motors and transmission components, and equipped with chip removal channels to realize centralized collection of wood chips generated in the sawing process.
The conveying mechanism adopts the chain plate conveying mode, which can be seamlessly connected with the conveying equipment of the preceding and subsequent processes of the production line. The conveying chain plate is assembled with high-strength chains and wear-resistant plates, and anti-slip baffles are arranged on the surface. The conveying speed can be adjusted according to log specifications to ensure steady transportation of logs to the sawing station. A tensioning device is configured for the conveying mechanism to adjust the tightness of the chain, so as to avoid conveying failures caused by loose or offset chains.
The sawing mechanism is the core functional unit of the equipment, consisting of saw blade, saw shaft, bearing pedestal and feeding device. The saw blade has a diameter of 1.2 meters. Made of high-manganese alloy, it features high hardness and wear resistance, and is applicable to the sawing of logs with different moisture contents and wood textures. The saw shaft is made of alloy steel after quenching and tempering treatment. High-precision bearing pedestals are installed at both ends of the saw shaft to reduce radial runout during operation and guarantee sawing accuracy. The feeding device adopts a mechanical positioning structure. Operators can adjust the sawing position according to actual processing requirements to complete fixed-width and fixed-thickness sawing of logs.
The drive system is composed of the main motor, pulley and transmission belt. The main motor is rated at 15kW with 4 poles, which can output stable rotating speed and provide sufficient cutting power for the saw blade. The transmission mechanism is fully enclosed for protection, preventing wood chips and dust from entering internal transmission parts. A tension pulley is equipped to adjust the tightness of the transmission belt and reduce slipping and vibration in the transmission process.
Safety protection devices include saw blade guard, feeding guard rail and emergency stop devices. The saw blade guard is a welded steel structure, covering the non-working area of the saw blade to prevent splashing wood chips and accidental contact by personnel. The feeding guard rails are installed on both sides of the conveying mechanism, which can limit log deviation and keep operators away from the sawing area. Emergency stop devices are arranged on the operation side and both sides of the equipment. Once triggered, the power supply will be cut off immediately to ensure operational safety.

The control panel is fitted with start-stop buttons, indicator lights and fault display components, enabling operators to monitor the operating status and troubleshoot faults in a timely manner.
The operation of the single-blade sawmill is closely linked with the preceding and subsequent processes of the production line. The overall working process is divided into five stages: log feeding, conveying and positioning, sawing operation, finished material conveying and wood chip collection.
In the log feeding stage, the feeding device at the front end of the production line transports logs to the inlet of the single-blade sawmill’s conveying mechanism. The chain plate drives the logs to move forward, and the logs enter the sawing area through the feeding guard rails. The anti-slip baffles on the conveying mechanism prevent logs from rolling during transportation and ensure logs enter the sawing station in a stable posture.
In the conveying and positioning stage, the logs are adjusted by the positioning device of the conveying mechanism to align the central line of logs with that of the saw blade, so as to avoid deflection in sawing. The mechanical baffle type positioning device can adjust the baffle spacing according to log diameters to adapt to logs of different specifications. When logs reach the sawing station, the photoelectric sensor of the conveying mechanism detects the material position and sends signals to the control unit to prepare for sawing.
In the sawing operation stage, operators start the main motor. The main motor drives the saw shaft and saw blade to rotate via pulleys. After the saw blade reaches the rated speed, the conveying mechanism drives logs to feed forward at a constant speed, and the saw blade performs cutting operation. Wood chips generated in the process are discharged through the chip removal channels at the bottom of the frame and collected by the supporting dust removal device of the production line to keep the working environment clean. The feeding speed matches the rotating speed of the saw blade, so as to obtain smooth sawing surfaces and reduce edge chipping and burrs.
After sawing, the processed log blanks are transported out of the sawing station by the conveying mechanism and delivered to the next equipment of the production line. The speed of the chain plate can be adjusted according to the overall production rhythm to match the operating speed of upstream and downstream equipment and ensure continuous operation of the whole production line. Waste materials and unqualified blanks generated in sawing are separated by the sorting device of the conveying mechanism to avoid affecting the processing of subsequent procedures.
In the wood chip collection stage, wood chips are delivered to the dust removal pipeline through the chip removal outlets, and collected and processed by the special dust removal system of the production line. The collected wood chips can be reused as biomass fuel or raw materials for plate processing, realizing comprehensive utilization of resources. The air volume of the dust removal fan matches the output of wood chips, ensuring timely discharge of chips and preventing material accumulation inside the equipment.
As key equipment of the production line, the single-blade sawmill possesses prominent technical characteristics and comprehensive application advantages.
First of all, the equipment has excellent structural stability. The frame is fabricated with thick steel plates and processed by stress relief annealing, so it will not deform or crack after long-term continuous operation.
