Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, embodiment does not form restriction of the present utility model:
Arrive Fig. 3 in conjunction with Fig. 1;
A kind of adjustable cutter device, it is characterized in that, comprise film machine bracing frame, motor is installed on it, on the motor pulley of described motor end, there is belt power connection for transmission shaft pulley, institute's power transmission shaft belt pulley is installed on wallboard by bearing and bearing block, described power transmission shaft belt pulley is with axle sleeve, bed plate power transmission shaft one end is compressed by the gripping mechanism of the other end, the other end is clamped in the axle sleeve of belt pulley, on described bed plate power transmission shaft, cover has the slip bed plate ring 24 of a shell-like, described slip bed plate ring 24 is fixed on bed plate power transmission shaft by screw, slip bed plate ring 24 can be installed by bearing 6, make bed plate power transmission shaft drive slip bed plate ring 24 to rotate, also comprise frame, described frame opposite side also comprises Rotatable pneumatic dop unit, described Rotatable pneumatic dop cellular installation is in frame, it comprises a housing, a cylinder is installed on housing, on the cylinder axis that described cylinder stretches out, there is transportable piston mechanism, described piston mechanism inside is provided with two bearings, in the middle of bearing, an end is installed and has the axle of dop, described end has axle one side of dop to be fixed on by screw on the end plate of bearing one side, described dop can be followed the motion of piston mechanism and move, described dop can block with the Bing Jiangqi two ends, end of bed plate power transmission shaft and pushes against, also can with the end separating of bed plate power transmission shaft, bed plate power transmission shaft can take out from cutter supporter.The technique effect of the essence that the technical scheme at this place plays is; cylinder drives transportable piston mechanism 20 to draw back; dop 19 does not push against bed plate power transmission shaft 5; bed plate power transmission shaft 5 just can be drawn out to change; change once just need to shut down with respect to originally going wrong, go up in a large number the situation that bolt etc. is lost time, greatly saved the time; quick turn-on, does not affect production.
As long as the structure of described dop can push against bed plate power transmission shaft 5, preferably its avris has faceplate.
Described bed plate power transmission shaft 5 avris have the device of two adjustment distances, the device of described adjustment distance comprises screw rod, described screw rod is through installing plate, on described installing plate, there is stiff end swivel nut 14, there is internal thread described stiff end swivel nut 14 inside, and cutter hub main body is installed on described installing plate, and described main body is extended with dise knife, described screw rod avris has handwheel 17, rotates handwheel and can drive installing plate to move on screw rod.The technique effect of the essence that the technical scheme at this place plays is that, by the rotation of handwheel 17, the rotation of drive screw rod, drives the variation of the position of installing plate, further adjusts distance.The avris of the device of described two adjustment distances also comprises and connects support 16, described connection is supported 16 inside and is comprised slideway, slides into inside sliding bearing is installed, and there is slide bar described sliding bearing inside, described sliding bearing top is connecting installing plate, and installing plate can connect slip in support 16.The technique effect of the essence that the technical scheme at this place plays is to make to slide more stable.
Belt between described motor pulley 2 and power transmission shaft belt pulley 3 is V-belt.
In conjunction with Fig. 4;
Belt surface between described motor pulley 2 and power transmission shaft belt pulley 3 has projection, on the race of described motor pulley 2 and power transmission shaft belt pulley 3, there is depression, described projection and depression can be agreed with, described being raised with more than one, described depression also has more than one, and the spacing between adjacent projection equals the spacing between adjacent groove.The technique effect of the essence that the technical scheme at this place plays is, makes the sliding band of belt, and this structural transmission is stable, and the phenomenon that can not dally also reduces belt wearing and tearing simultaneously, is a kind of novel structure.
It should be noted that, above drive mechanism also can be applied for a patent separately.
Taking the motor that is installed on frame as power, by V--belt Drive, drive bootom couch cutter shaft to rotate forward or backwards.When standard is bed plate rotating speed 1.2 times of sheet base speed.Be sheet base running speed while being 80 ms/min, cutting knife running speed is controlled at 95 ms/min of left and right, and while normally work, cutting knife rotation direction moves towards identical with sheet base, forms shear effect.Cutting knife main body has incision and two the main actions that recline, and controls by manual control air valve is unified.Upper dise knife and bed plate keep the drift angles of 1.5 degree, and have elastomer to connect, can go up dise knife and abut in more completely on bed plate ring, the two intersect 3 millimeters be advisable, and can manually adjust.Shearing width drives the cutter supporter of both sides to adjust respectively its position by the manual pulley of wallboard both sides and completes.
More than show and described general principle of the present utility model, principal character and advantage of the present utility model.Those skilled in the art should understand the utility model and not be restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope.
