Embodiment 1

[0052] See figure 1 shown.

[0053] The invention includes: a liquid storage tank 1, a liquid flow regulating valve 2, a cooling device 3, a liquid pipeline 4, an atomized steam temperature controller 5, a mixing chamber 6, an atomized steam temperature detection sensor 7, a uniform supply nozzle 8, multiple Blade saw 9, non-contact temperature detector 10, cooling controller 11, ultrasonic atomization device 12, cold air pipeline 13, gas flow regulating valve 14, gas storage tank 15, gas source pipeline 16 and gas volume regulating valve 17, etc. composition.

[0054] The outside air first enters the air compressor to form compressed air. The compressed air enters the air storage tank 15 through the air source pipeline 16, a part of the gas passes through the air volume regulating valve 17 and enters the cold air pipeline in the cooling device through the gas pipeline, and the other part of the gas passes through the gas pipeline. The flow regulating valve 14 enters the liq...

Embodiment 2

[0056] See figure 2 As shown, the present invention is a wood and bamboo sawing cooling system with multiple saw blades. 5', cooling device 6', atomized steam temperature detection sensor 7', uniform supply nozzle 8', multi-blade saw 9', non-contact temperature detector 10', cooling controller 11', gas pipeline 12', The gas flow regulating valve 13', the gas storage tank 14', the gas source pipeline 15' and the gas flow regulating valve 16' are composed of.

[0057] The outside air first enters the air compressor to form compressed air, the compressed air enters the air storage tank 14' through the air source pipeline 15', a part of the gas enters the mixing chamber 4' through the gas volume regulating valve 13' and the gas pipeline 12', and the other part of the gas Enter the liquid storage tank 1' through the gas flow regulating valve 16', enter the ultrasonic atomization device 3' through the liquid pipeline through the liquid flow regulating valve 2', and the ultrasonic ...

Embodiment 3

[0059] Traditional circular nozzles such as image 3 As shown, 100 is a nozzle seat, 101 is a nozzle hole, and 102 is a multi-saw blade group. When the circular nozzle hole 100 sprays atomized gas, the shape of the spray is mainly circular and fan-shaped. This type of nozzle produces When the spray is applied to the multi-saw blade group 102, the amount of atomized liquid droplets scattered on each saw blade is different, which will make the cooling effect between the saw blades inconsistent, and may also cause deformation of the saw blades.

[0060] A kind of narrow slit variable section nozzle of the present invention, such as Figure 4 As shown, 100' is a nozzle seat, 101' is a narrow slit variable-section nozzle, 102' is a multi-saw blade group, and the nozzle 101' is a long hole gradually narrowed from the middle to both ends in the length direction. Because the saw blades in the saw blade group 102' are not suitable for heat dissipation, the saw blades in the middle pos...

Abstract

The invention discloses a multi-saw blade sawing and cooling system of woods and bamboos. The multi-saw blade sawing and cooling system comprises an air storage tank, a liquid storage tank, a cooling device, an ultrasonic atomization device, a mixing chamber and a spray head, wherein the air storage tank is provided with two output pipelines for outputting compressed gas; cooling liquid is stored in the liquid storage tank; the liquid storage tank is connected with one output pipeline of the air storage tank; the cooling device is used for cooling compressed air output by the other output pipeline of the air storage tank and the cooling liquid output by the liquid storage tank to pre-determined temperature; the ultrasonic atomization device is used for ultrasonically atomizing the cooled cooling liquid to form cooling gas; the mixing chamber is used for mixing the atomized cooling air and the cooled compressed air to form mixed gas; and the spray head is used for spraying the mixed air to a cutting region of the woods or the bamboos to cool a saw blade set in the cutting region. The multi-saw blade sawing and cooling system disclosed by the invention is capable of cooling the compressed air and the cooling liquid at the same time and sufficiently atomizing the cooling liquid through the ultrasonic atomization device and finally forming low-temperature atomization steam, thus, the lubrication cooling effect is good.

Description

technical field [0001] The invention relates to a wood or bamboo sawing cooling system with multiple saw blades, which is mainly aimed at the splitting of precious wood and the sawing processing of recombined bamboo floors for multi-layer solid wood composite floor boards. The invention can be directly matched with sawing machine tools Use, reduce heat deformation of the saw blade, save processing energy consumption, reduce wood sawing loss, prolong the service life of the saw blade, and improve processing quality. Background technique [0002] With the improvement of my country's national economic level, the development of China's furniture and flooring industry, especially multi-layer solid wood composite flooring and recombined bamboo flooring, is increasing year by year for precious wood and bamboo. However, my country's implementation of the "Natural Forest Protection Project" has led to increasingly prominent contradictions between the supply and demand of timber raw m...
