20080308185 | WOOD PLANING MACHINE INCLUDING A ROUGH-PLANE CUTTER AND A FINE-PLANE CUTTER - A wood planing machine includes a base adapted to permit a workpiece to be moved thereon in a front-to-rear direction, a plurality guide posts fixed on the base, a mounting seat sleeved movably on the guide posts, a motor disposed on the mounting seat, and a cutting unit disposed on the mounting seat. The cutting unit includes a rough-plane cutter, a fine-plane cutter disposed behind the rough-plane cutter, a first transmission unit interconnecting the motor and the rough-plane cutter to allow the rough-plane cutter to be driven by the motor, and a second transmission unit interconnecting the rough-plane cutter and the fine-plane cutter to allow rotation of the rough-plane cutter to be transferred to the fine-plane cutter. | 12-18-2008 |
20090236010 | CUTTER HEAD ASSEMBLY FOR A WOOD PLANING MACHINE - A cutter head assembly for a wood planing machine includes a shaft, a plurality of cutter-mounting sleeve modules sleeved on the shaft, and a plurality of cutter modules respectively secured to the sleeve modules such that cutting edges of the cutter modules extend beyond outer wall surfaces of the sleeve modules. An angularly variable positioning mechanism includes an axially extending guiding member disposed on the mount segment, and a plurality of axially extending guided members disposed on inner wall surfaces of the sleeve modules to mate with the axially guiding member. By virtue of fitting engagement between the guiding member and a selected one of the guided member of each sleeve module that are sequentially sleeved onto the shaft, the cutting edges together define a cutting contour line that winds around the shaft. | 09-24-2009 |
20090260245 | Level adjusting device for a cutter head of a jointer/planer machine - A level adjusting device for a cutter head of a jointer/planer machine, includes a front support frame for supporting a front anti-friction bearing unit that holds a front journal segment of the cutter head, a rear support frame including left and right base abutments, a height-adjustable carrier for receiving a rear anti-friction bearing member that holds a rear journal segment of the cutter head, left and right lugs respectively having inner tubular threaded surfaces, and left and right adjusting screws respectively having threaded segments which are threadedly and respectively engaged with the inner tubular threaded surfaces, and abutting ends which are in frictional engagement with the base abutments, respectively, and which are turnable to move the respective lugs relative to the adjusting screws so as to raise or lower the carrier, thereby enabling level adjustment of the cutter head. | 10-22-2009 |
20090283660 | Carrier of a wood planer for carrying a cutter and a motor - A light weight carrier movable along vertical guide posts of a wood planer includes left and right mounting seats having front and rear support blocks projecting oppositely and inwardly therefrom, front and rear guide holes adapted for extension of the guide posts, and cutter mounting holes each disposed between front and rear support blocks and between the front and rear guide holes, front and rear connecting rods each having left and right end sections respectively connected to the left and right mounting seats at the front and rear support blocks; a motor mounting plate fixed between the front support blocks; and a rear cover plate fixed between the rear support blocks. | 11-19-2009 |
20100005603 | APPARATUS FOR DELIVERING OR WITHDRAWING A FLEXIBLE TUBULAR CASING OF A PIPE CLEANING DEVICE - An apparatus includes a driving shaft which is disposed in a housing unit, which is rotatable with a drive unit, and which is adapted to be coupled with a flexible twisting member disposed in a flexible tubular casing of a pipe cleaning device to rotate a scrubbing head for scrubbing an inner wall of a pipe, and a plurality of rollers cooperatively defining a traveling path. One of the rollers is rotatable with the driving shaft. The flexible tubular casing is drawn by the rotation of the rollers to move along the traveling path so as to be delivered or withdrawn. A control module is disposed to control the operation of the drive unit. A switch unit is actuated to send a switch-off signal to the control module when the flexible tubular casing is tensed so as to stop the drive unit. | 01-14-2010 |
20100043921 | CUTTER HEAD ASSEMBLY FOR A WOOD PLANING MACHINE - A cutter head assembly for a wood planing machine includes a rotary shaft, a plurality of blade carriers non-rotatably retained on the shaft, and a plurality of cutter blades respectively secured on outer wall surfaces of the blade carriers by means of a plurality of screw fasteners. The outer wall surface of each blade carrier includes a leading region and a trailing region that form a first included angle of at least 90 degrees therebetween. Each blade has a first major wall surface abutting against the leading region, a second major wall surface disposed opposite to the first major wall surface, a cutting edge interposed between the first and second major wall surfaces and extending beyond the outer wall surface of the respective blade carrier, and an abutting edge disposed opposite to the cutting edge to abut against the trailing region. The cutting edge of each cutter blade intersects the second major wall surface at a second included angle ranging from 35 degrees to 45 degrees. | 02-25-2010 |
20100282365 | CUTTER HEAD OF A PLANAR MACHINE - A cutter head of a planer machine includes a rotatable mount body having opposite flat mount and counter regions that are symmetrical to each other, a cutter blade disposed to abut against the flat mount region so as to enable a cutting edge to extend beyond a lateral end of the mount region, a press member having a tightened body which is tightened against the mount region, and a pressing strip which is brought to press the cutter blade against the mount region, and a counterweight disposed on the counter region so as to balance the combined weights of the cutter blade and the press member for smoothing the rotation of the mount body. | 11-11-2010 |
20110167976 | ANTI-KICKBACK DEVICE FOR A TABLE SAW MACHINE - An anti-kickback device includes a riving knife mounted rearwardly of a saw blade of a table saw machine and having a retaining hole. An elongate mount has a cavity and an insert groove to receive the plate body such that the retaining hole is located in the cavity. A fastening unit includes a post which is received in the cavity, which straddles a top surface of the knife, and which has a radial bore registered with the retaining hole, a detent body disposed in the radial bore and movable to extend into or to be clear of the retaining hole to thereby permit the mount to be secured to or detached from the knife, a tubular actuator which has an inner cam surface configured to move the detent body, and an operating member manually operable to move the actuator. | 07-14-2011 |
