As shown in Figure 7; annular saw protective device 6 comprises positioning seat 41, DOCK LEVELER 42, gripper shoe 43, connecting plate 44 and semicircle protective cover 45; the side of cabinet 1 is provided with 2 positioning seats 41; DOCK LEVELER 42 is located between 2 positioning seats 41; the upper end of DOCK LEVELER 42 is provided with gripper shoe 43; the top of DOCK LEVELER 42 is by the end active link of bearing pin 46 with connecting plate 44, and the other end of connecting plate 44 is fixedlyed connected with semicircle protective cover 45.The bottom of cabinet 1 also is provided with dust catcher 48, and dust catcher 48 is connected with the top of semicircle protective cover 45 by sweep-up pipe 47.
As shown in Figure 8, sound absorbing layer 49 is made up of rock wool layer 50, surperficial abatvoix 51 and sound-absorption hole 52, and rock wool layer 50 bonds together with surperficial abatvoix 51, and sound-absorption hole 52 is evenly distributed on the surperficial abatvoix 51.
Operation principle of the present invention: in the time of need cutting work, the wood size of cutting is regulated the height of annular saw protective device 6 at first as required, when needs reduce the height of annular saw protective device 6, take down the alignment pin on the positioning seat 41, then DOCK LEVELER 42 is adjusted downwards, when highly suitable, insert alignment pin, with DOCK LEVELER 42 location; When the height of needs rising annular saw protective device 6, take down the alignment pin on the positioning seat 41, then DOCK LEVELER 42 is adjusted upward, when highly suitable, insert alignment pin, can with DOCK LEVELER 42 positioning instants.Behind the position suitable of high annular saw protective device 6; connect power supply; dust catcher 48 and drive motors 7 are worked simultaneously; the wood chip and the dust that are produced during cutting timber are rolled by annular saw 17; sweep-up pipe 47 by semicircle protective cover 45 tops siphons away, and enters into dust catcher 48 inside along sweep-up pipe 47 and stores.
When needs are changed the model of annular saw 17, at first with pin 38 around rotating shaft C 39 Rotate 180 degree, with the hands be pulled outwardly then and start to take turns 26, in pulling handwheel 26, triangle positioning seat 23 breaks away from triangle locating slot 37 simultaneously, annular saw positioning seat 27 breaks away from rotating shaft A11 simultaneously, when triangle positioning seat 23 breaks away from triangle locating slot 37 fully, with the hands rotation hand wheel 26, make triangle positioning seat 23 rotations 120 degree, driving central shaft 18 in rotation hand wheel 26 rotates, central shaft 18 drives conversion seat 20 and rotates, conversion seat 20 rotates and drives 21 rotations of annular saw mount pad, when handle rotation 120 is spent, the annular saw mount pad that another one model annular saw is installed just in time aligns with rotating shaft A11, both hands are with handwheel 26 pushed home then, when promoting handwheel 26, keyway on the annular saw positioning seat 27 is inserted on the rotating shaft A11 slowly, when triangle positioning seat 23 enters triangle locating slot 37 fully, with pin 38 C39 Rotate 180 degree around the shaft, the other end of pin 38 just in time places in the holder fast 40 and gets final product.This moment, triangle positioning seat 23 was by locked, even machine has vibration also can not break away from triangle locating slot 37.
When connecting power supply, drive motors 7 begins rotation, belt pulley A9 on the drive motors 7 drives belt B10 by power transmission belt 8 and rotates, belt pulley B10 drives rotating shaft A11 and rotates, rotating shaft A11 drives annular saw mount pad 21 and rotates, because annular saw is installed on the annular saw positioning seat 27, by positioning key 34 and setscrew nut 35 annular saw 17 is positioned on the annular saw positioning seat 27, follow annular saw positioning seat 27 and together rotate, annular saw positioning seat 27 together rotates by the rotating shaft B29 drive rolling bearing of being located in the rolling bearing 30 30.
The inventor sums up in the long-term production practice, adopt this low noise multitool head cutting bench saw can improve 20% than traditional bench saw operating efficiency, under same staff's situation, monthly income when adopting the monthly income ratio employing tradition cutting bench saw under the low noise multitool head cutting bench saw situation improves 50,000 yuan, is a very great breakthrough.
Because traditional cast-cutting saw can produce huge noise when carrying out cutting operation, therefore influence neighbours' normal life.And this low noise multitool head cuts effectively noise reduction of bench saw, when sound wave is got on the surperficial abatvoix, is disperseed by the sound-absorption hole on the surperficial abatvoix, and the sound wave that enters sound-absorption hole can't return on former road, has therefore reduced noise.Dispersed sound wave is along with sound-absorption hole is delivered on the rock wool layer, because the inside of rock wool has a large amount of micro pores, sound wave can enter into material internal along these spaces, with material generation rubbing action, acoustic energy is changed into heat energy, thereby play the effect of secondary noise reduction.
The present invention can change the saw blade of different model fast, for the staff saves a large amount of time, greatly increases work efficiency.And the function with dust suction prevents that effectively wood chip and dust from dancing in the air everywhere, guarantees the clean and tidy of working environment.Effectively noise reduction effectively prevents noise pollution.
