Detailed description of the invention
Now lift following examples and by reference to the accompanying drawings structure of the present invention and effect be elaborated.
As shown in Figure 1; for using the band sawing machine 10 of safety protection mechanism 20 of a preferred embodiment of the present invention; band sawing machine 10 shown in figure consists predominantly of pedestal 11 on, once the saw band 15 of driving wheel 14 and driven pulley 13 is located at driven pulley in pedestal 11 13, and is located at driving wheel in lower pedestal 12 14, and is set around by pedestal 12,, and one is located at lower pedestal 12 and connects the motor 16 of driving wheel 14.Please coordinate with reference to Fig. 2 and Fig. 3, safety protection mechanism 20 of the present invention has a relay 30, a tension adjusting device 40, and a pressing plate 60.
Relay 30 is fixed in pedestal 11 and electrical connection motor 16, for controlling the action of motor 16.In the time that a wheel trolley 32 of relay 30 is not pressed, relay 30 can present opening and can export an electric current to motor 16, motor 16 can be activated, when the wheel trolley 32 of relay 30 is during by pressed by external force, relay 30 can present closed condition and interrupt output to the electric current of motor 16, motor 16 cannot be activated.
Tension adjusting device 40 has a holder 41, an elevating bracket 42, a Control Component 43, a trimming assembly 44, and a tension force pointer 45, wherein:
Holder 41 is fixed on pedestal 11 and has one first fixed block 412 and 2 second fixed block 414, two second fixed blocks 414 relatively lock in the two sides of the first fixed block 412.
Elevating bracket 42 has two relative axostylus axostyle 421, a top board 422, a base plate 423, wheel seats 424, wherein: two axostylus axostyles 421 are arranged in the first fixed block 412 of holder 41 and can move up and down along the axially relative holder 41 of itself; Top board 422 and base plate 423 are connected to top, the two ends, the end of two axostylus axostyles 421, and top board 422 and base plate 423 can be moved along with two axostylus axostyles 421; Wheel seat 424 is sheathed to be fixed on two axostylus axostyles 421 and between top board 422 and base plate 423, to be pivoted for driven pulley 13.Thus, elevating bracket 42 can be risen or be declined by the synchronous relative holder 41 of driven pulley 13 that drives of wheel seat 424.In addition, elevating bracket 42 has two spacing rings 425, and each spacing ring 425 is fixed on axostylus axostyle 421 and between top board 422 and wheel seat 424, for stop wheel seat 424 on move.
Control Component 43 has leader 46 and a cam bit 47, and the sheathed rotating shaft 462 of being fixed on handle 46 of cam bit 47, can rotate by the driving of handle 46 cam bit 47 relative to elevating bracket 42.Cam bit 47 has a large-diameter portion 472 and a minor diameter part 474, as shown in Figure 3 to Figure 4, minor diameter part 474 wherein has one against plane 476, in addition, cam bit 47 is provided with a stop part 48, stop part 48 protrudes from the surface of cam bit 47, as shown in Figure 3, provides locating effect for the top board 422 of butt elevating bracket 42.
Trimming assembly 44 has a supporting plate 50, a helical spring 51, a nut 52, an adjusting lever 53, a thrust bearing 54, and a runner 55.Supporting plate 50 is folded between two axostylus axostyles 421 of elevating bracket 42 and between wheel seat 424 and base plate 423; Helical spring 51 is located between the wheel seat 424 of supporting plate 50 and elevating bracket 42; Nut 52 is fixed on the base plate 423 of elevating bracket 42; Adjusting lever 53 is arranged in the base plate 423 of supporting plate 50 and elevating bracket 42 rotationally, and stretches in helical spring 51 with its one end, and adjusting lever 53 has a threaded portion 532, establishes nut 52 for spiral shell.Thrust bearing 54 is sheathed on adjusting lever 53 and is connected to the bottom surface of supporting plate 50; Runner 55 is fixed on one end of adjusting lever 53 and exposes to outside pedestal 11, for driving adjusting lever 53 to rotate.
Tension force pointer 45 is hubbed at pedestal 11 and has a chute 452 with its one end, in being plugged in slippingly for a protruding axle 56 of supporting plate 50, make tension force pointer 45 to produce pivotable along with moving up and down of supporting plate 50, for coordinating a sight scale division (not shown) to indicate the elasticity of current saw band 15.
Pressing plate 60 connects the top board 422 of elevating bracket 42 with its one end and is positioned at the top of relay 30, makes pressing plate 60 can be left or compress by the lifting of elevating bracket 42 wheel trolley 32 of relay 30 with its other end.
In the time will loosening saw band 15, first down pulling handle 46 and cam bit 47 is turned to an off-position P1, as shown in Figure 4, elevating bracket now 42 can because weight own drop to the minor diameter part 474 that allows top board 422 be resisted against cam bit 47 against plane 476, make driven pulley 13 to shorten the distance between driving wheel 14 along with the decline of wheel seat 424, pressing plate 60 also can compress along with the decline of top board 422 wheel trolley 32 of relay 30 simultaneously, motor 16 cannot be activated, thus, saw band 15 just can present lax state and motor 16 also can present off-position, under the situation of safety, carry out the dismounting of saw band 15 in order to operating personnel.
On the contrary, in the time will saw band 15 being installed, be that handle 46 is up pulled, make cam bit 47 turn to a packing position P2, as shown in Figure 3, stop part 48 now can be connected to the top board 422 of elevating bracket 42 to complete the location of cam bit 47, elevating bracket 42 now can be subject to cam bit 47 large-diameter portion 472 ejection and on lift, in the process of lifting on elevating bracket 42, synchronously drive driven pulley 13 away from driving wheel 14 except passing through wheel seat 424, simultaneously also can be by top board 422 Timing Belt dynamic pressure plates 60 away from relay 30, in the case, saw band 15 can be presented state and the motor 16 tightened by driven pulley 13 supports and be activated once again, so can drive saw band 15 to carry out sawing operation.
In addition, for the tension adjustment of saw band 15 is arrived to suitable elasticity, operating personnel can drive adjusting lever 53 to rotate by runner 55, because nut 52 maintains static, so adjusting lever 53 can be along own axially up moving, and up promote supporting plate 50 by thrust bearing 54 in mobile process, then supporting plate 50 meeting extrusion spiral springs 51, extruded helical spring 51 is understood up ejection wheel seat 424 again, driven pulley 13 is up moved, as shown in Figure 5, wheel seat 424 now can be subject to stopping of two spacing rings 425 and can only produce microdisplacement, to reach the effect of fine setting elasticity.
In sum, safety protection mechanism 20 of the present invention can guarantee that motor 16 only can be activated the tension adjustment of saw band 15 at tension adjusting device 40 under tight state, so just can avoid unexpected generation and reaches the object of lifting operation security.It should be added that in addition, tension adjusting device 40 is not limited to above-mentioned mentioned structural design, can drive the elevating bracket 42 of driven pulley 13 liftings can reach the effect of adjusting saw band 15 tension force as long as in fact have.
Finally, the composed component that the present invention disclosed in the aforementioned embodiment, only for illustrating, is not used for limiting the scope of patent protection of this case, and substituting or changing of other equivalence elements, also should be contained by the scope of patent protection of this case.
