Description

A kind of plasterboard saws at a high speed denoising device

Technical field

The utility model belongs to plasterboard renovation technique field, and in particular to a kind of plasterboard saws at a high speed denoising device.

Background technology

Using disconnected trigger during plasterboard fixed ruler cutting, the plasterboard kerf quality that it cuts out is poor, and flash compares Many, otch is uneven, and aesthetic property is substantially reduced.After producing secondary cut is needed due to there is flash.With science and technology The development of level, people begin to use electric cutting saw, and most of electric cutting saw is all one motor of setting in cabinet, Motor drive saw blade carries out cutting work.In plasterboard cutting process, the use that three controls are sawed at a high speed is more and more universal, but three Saw operationally, very big noise can be produced in trimming because saw blade rotating speed is high at a high speed for control, had a strong impact on the work of workman, Noise pollution is produced to environment.Three control edge sealing personnel are needed to be worked 8 hours in high speed saw and its periphery daily, and this is listened them Power affects.In addition, certain dust can be produced during three control trimmings, bag can be caused to gather dust if sealing effectiveness is not good Dust collection effect is bad, causes dust to diffuse, and body is endangered in workman's suction lung.The saw blade for failing to realize at present is cut when using Noise control and the Synchronization Control of dust Control, therefore, a kind of plasterboard saw denoising device at a high speed how is researched and developed, with important Realistic meaning.

Utility model content

For the big technical problem of high speed saw blade noise present in prior art, the purpose of this utility model is to provide A kind of plasterboard saw denoising device at a high speed, can not only solve plate and cross noise that saw produces but also be prevented from dust and leak to carry Dust collection effect high.

The technical scheme that the utility model is taken is：

A kind of plasterboard saws at a high speed denoising device, including high-speed electric expreess locomotive, high speed saw saw blade and protective cover, the high speed saw saw Piece is symmetricly set on sheet material both sides along the terminal that sheet material enters plate direction, and the rotating shaft connection of saw saw blade and high-speed electric expreess locomotive, high at a high speed Protective cover is provided with the outside of speed saw saw blade, protective cover is set to hollow square shell and is symmetricly set on the madial wall of shell two V-arrangement baffle plate, between V-arrangement baffle plate and shell be filled with rock wool, the two side that shell is cut in outside the upper and lower end of protective cover symmetrically sets Hemispherical projections are equipped with, hemispherical projections are set to the hollow double membrane structure formed by adventitia and inner membrance.

Further, the high speed saw saw blade enters plate direction and is oppositely arranged perpendicular to sheet material.

Further, the V-arrangement baffle plate is provided with inward recess on the madial wall of rock wool, and inward recess is set to hollow vertebra Body structure.

Further, the V-arrangement baffle plate on the lateral wall of rock wool away from being provided with acoustical cotton.

Further, the thickness of the acoustical cotton extends trapezoidal successively passing from the up and down two ends of V-arrangement baffle plate point of intersection Increase.

The beneficial effects of the utility model are：

The protective cover of special construction is provided with the utility model on the outside of high speed saw saw blade, when gypsum board panels enter saw When, saw saw blade can produce noise and dust at cutting plate end at a high speed, and protective cover is interior will by V-arrangement baffle plate and hemispherical projections The inner chamber of shell is divided into many spaces, and noise is reduced step by step during propagation, the hollow bilayer formed by adventitia and inner membrance The hemispherical projections of membrane structure, the effect of the vibration frequency of cut material when can effectively reduce sawing, arc outer wall is by increase Contact area and improve the dust removal ability of protective cover, it is ensured that the good dedusting function of cutting mechanism；V-arrangement baffle plate plays good branch Support is acted on, the effect with protection square shell, can effectively reduce containment weight and manufacturing cost, and acoustic material rock wool is filled out Fill, soundproof effect played in the case where maximum gauge is ensured, thus noise reduction protective cover can play the propagation of block noise with And the diffusion double action of dust.

V-arrangement baffle plate in the utility model is provided with the inward recess of hollow vertebral body structure on the madial wall of rock wool, knot Structure is novel, and noise while annular diffusion, by the collision of centrum arcwall, effectively reduces noise, sound-absorbing in inward recess Effect is good, and can also reduce the diffusion of dust, improves dust collection effect, clears up convenient and swift, practical.

V-arrangement baffle plate carries out the increase and decrease of thickness away from the acoustical cotton set on the lateral wall of rock wool in installation process, ensuring In the case of feasibility, thickness is increased, can effectively reduce noise, reduce the noise pollution to environment, protective cover hollow space Set, the wood chip and dust that will can be produced in cutting are drawn onto inside dust catcher and are stored, reduce dust recycling, be work people Member provides a clean working environment.The overall structure of protective cover, when staff is worked, can effectively protect work people The personal safety of member.
