[0002] Wood is the only renewable material among the four main materials. After the logs are harvested and collected, the branches on the surface of the logs are removed and the next processing step can be carried out. The logs are cut into specified lengths and then cut into boards or strips. The wood can be processed into any shape to suit various usage scenarios. When a multi-blade saw is used to cut boards, a large amount of debris and dust is often generated. The debris and dust splash and drift to the outside, which can easily affect the staff and the environment and is not conducive to environmental protection. Therefore, a new type of green and environmentally friendly wood cutting machine is designed to change the above technical defects. Utility Model Content

[0003] In order to overcome the technical defects of the prior art, the utility model provides a green and environmentally friendly wood cutting machine, which aims to solve the technical problem that under the prior art, a large amount of debris and dust are generated when cutting wood, and the debris and dust are splashed and dispersed to the outside, which easily affects the staff and the environment and is not conducive to environmental protection.

[0004] The technical solution adopted by the utility model is: a green and environmentally friendly wood cutting machine, which includes a shell, a first conveyor is installed at the left end of the shell, three brackets are rotatably installed inside the shell, and the outer surface of the bracket is fixedly connected to the inner wall of the shell through a strong spring, a positioning roller is rotatably installed inside the bracket, two rotating rods are installed through the outer surface of the shell, and the outer surface of the rotating rod is installed with cutting blades arranged at equal distances, a stepper motor is installed on the outer surface of the shell, and the output end of the stepper motor and the outer surface of the rotating rod are both installed with transmission wheels, and the three transmission wheels are connected by chains. Transmission connection, a second conveyor is installed inside the shell, the conveyor belt surfaces of the first conveyor and the second conveyor are both installed with first anti-slip teeth, the outer surface of the positioning roller is installed with second anti-slip teeth, a mesh conveyor is installed at the right end of the shell, a positioning plate is installed inside the mesh conveyor, a vibration roller is installed above the positioning plate through a vibration spring, a vibration motor is installed on the outer surface of the vibration roller, an air nozzle is installed through the outer surface of the shell, a fan is installed on the top surface of the shell, an air pipe is installed at the output end of the fan, and the air pipe is connected to the air nozzle, and a dust collection belt is installed through the outer surface of the shell.

[0005] When the wood cutting machine of the present technical solution is used, the first conveyor, the second conveyor and the mesh conveyor are powered on and started, and the cut logs are placed on the first conveyor. The first conveyor transports the logs into the shell. When the logs are transported to the bottom of the positioning roller, they press against the positioning roller and rotate up with the bracket. Under the action of the strong spring force, the bracket and the positioning roller are pushed downward to rotate and press the log to position it. The stepper motor is powered on and started to rotate. Under the action of the transmission wheel and the chain drive, the rotating rod and the cutting blade are rotated. As the logs are transported by the first conveyor, they come into contact with the cutting blade and are cut into boards and transported to the second conveyor. The fan is powered on and started to blow air through the air pipe from the air nozzle. The air nozzle blows air to the cut seam of the log to blow off and collect the adhered debris and dust. The air at both ends of the shell is blown away by the air nozzle. The debris and dust are concentrated in the outer shell to prevent splashing and scattering, and are collected. The scattered debris falls into the outer shell, and the fine dust enters the dust collection belt with the air. The dust collection belt filters, intercepts and collects the dust. The logs cut into boards are transported by the second conveyor and fall onto the mesh conveyor for transportation. The vibration motor is powered on and starts, and the vibration roller vibrates and hits the mesh conveyor to make the board vibrate and shake off the debris and dust. Under the action of the air blowing from the air jet nozzle, the debris and dust are blown into the outer shell for collection, and the board is sent out of the shell with the mesh conveyor to prevent the surface debris and dust from falling and scattering into the air when the board is taken out and falls. This solves the technical problem that a large amount of debris and dust is generated when traditional wood is cut into boards, and the debris and dust splash and scatter to the outside, which easily affects the staff and the environment and is not conducive to environmental protection.

[0006] Preferably, door curtains are installed at both ends of the shell. Through the provision of the door curtains, both ends of the shell are blocked to prevent debris and dust in the shell from scattering and splashing.

[0007] Furthermore, a protective shell is fixedly connected to the outer surface of the housing, and the transmission wheel and the chain are located inside the protective shell. The protective shell is provided to prevent the transmission wheel and the chain from being exposed to the outside world and causing potential safety hazards.

[0008] Furthermore, a rubber tube is provided on the outer sleeve of the powerful spring, and the two ends of the rubber tube are fixedly connected to the outer surface of the bracket and the inner wall of the shell respectively. Through the provision of the rubber tube, the powerful spring is protected to avoid damage to the powerful spring caused by external influences.

[0009] Furthermore, the outer surface of the shell is rotatably hinged with a sealing door. Through the provision of the sealing door, the shell can be opened to clean up the wood chips inside it.

[0010] The beneficial effects of the utility model are:

[0011] The utility model starts by energizing the first conveyor, the second conveyor and the mesh conveyor, and puts the cut logs on the first conveyor. The first conveyor conveys the logs into the shell. When the logs are conveyed to the bottom of the positioning roller, they press the positioning roller and rotate with the bracket to rise. Under the action of the strong spring elastic force, the bracket and the positioning roller are pushed downward to rotate and press the log to position it. The stepper motor is energized to start the rotation and rotates with the rotating rod and the cutting blade under the action of the transmission wheel and the chain transmission. As the logs are conveyed by the first conveyor, they come into contact with the cutting blade to be cut into boards and conveyed to the second conveyor. The fan is energized to start the blowing and the air is ejected from the air nozzle through the air pipe. The air nozzle blows the adhered debris and dust at the log cut seam to be blown off and collected. The air nozzle blows the scattered debris and dust into the shell through the air at both ends of the shell. The scattered debris is collected in a concentrated manner to prevent splashing and scattering. The scattered debris falls into the shell, and the fine dust enters the dust collection belt with the air. The dust collection belt filters, intercepts and collects the dust. The logs cut into boards are transported by the second conveyor and fall onto the mesh conveyor for transportation. The vibration motor is powered on and starts, and the vibration roller vibrates and hits the mesh conveyor to make the board vibrate and shake off the debris and dust. Under the action of the air blowing from the air jet nozzle, the debris and dust are blown into the shell for collection, and the board is sent out of the shell with the mesh conveyor to prevent the surface debris and dust from falling and scattering into the air when the board is taken out and falls, so as to realize the cleaning of the cut board. This solves the technical problem that a large amount of debris and dust is generated when traditional wood is cut, and the debris and dust splash and scatter to the outside, which easily affects the staff and the environment and is not conducive to environmental protection.
