Abstract
The invention relates to a transporting roll platform structure of roll wheel transportation sanding machine. Two or a plurality of transporting rolls are positioned on an axial seat in a roll platform frame; one end of the two or the plurality of transporting roll are respectively connected with a reduction gearbox located outside the roll platform frame through a transporting shaft and a universal joint; one roll or two or a plurality of lower support rolls are respectively distributed among a plurality of transporting rolls and the lower support rolls are driven by the transporting rolls through a transmission mechanism. The invention has the advantages that: first, the lower support roll adopts the adjustable structure and is designed into the structure with one side adjustable or twosides adjustable, which greatly facilitates the adjustment of sand cutting capacity at the two sides in grinding and overcomes the defects in background technology; second, a cross drive transportingrolls formed by the transporting shaft and the universal joint is used for minimizing a tolerance clearance; third, the reduction gearbox is positioned outside the roll platform frame, thus narrow the roll platform frame, lightening the weight as well as improving rigidity of the roll platform frame, a machine frame and a sanding joint; fourth, convenience and reliability of maintenance are greatly improved.
Description
Technical field
The present invention relates to a kind of running roller and carry the conveying roller platform structure of sander, belong to the sander component assembly and make the field.
Background technology
Existing sander delivering roller jack horse, on structural design, the one, because the fine setting between snub pulley and sanding roller is to realize by lifting sanding roller main shaft, and the sanding roller is high accuracy in the sander, high-revolving critical piece, the structure of many activities will produce the gap of cooperation, thereby reduce the precision of running, make it to exert an adverse impact running up.Its two, both sides that this mechanism can only synchronization lifting sanding roller, and can't monolaterally adjusting; The 3rd, reduction box is positioned at the roller stand and directly is connected with carrying roll shaft; The 4th, snub pulley is fixed structure, spacing between sanding roller and the snub pulley is to rely on the integral elevating of roller platform and transfer the sanding roller to realize, its weak point: the one, reduction box is positioned at the roller stand, not only make the Heavy Weight of roller stand but also increased the width of roller stand, thereby reduced the rigidity of roller stand, and the rigidity of lower bearing bracket and sanding head; The 2nd, because reduction box is positioned at the roller stand, not only poor reliability, and inconvenient maintenance.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, designing a kind of one is the gap of adopting between snub pulley fine setting and sanding roller, but and adopt both synchronization liftings of both sides, also can distinguish lifting, to reach the maximum flexibility of adjustment; The 2nd, reduction box is positioned at outside the roller stand, to alleviate roller stand weight and width; The 3rd, the conveying axis of reduction box adopts the cross axle transfer motion power, and is little to reach the transmission fit clearance, can guarantee under the situation of reduction box off normal the operate as normal of conveying roller and convenient for maintaining in certain scope.
Design: in order to realize above-mentioned purpose of design.1, adopt snub pulley adjustable, it is one of feature of the present invention, because snub pulley is the low-speed running parts, realize that its high-precision lifting is easy to many than the high accuracy lifting that realizes high-speed component, secondly, but the present invention adopts both synchronization liftings of both sides, also can distinguish lifting, has greatly improved the flexibility of its adjustment.2, conveying roller is positioned at the roller stand, reduction box is positioned at outside the roller stand, is two of feature of the present invention.Reduction box is put into the outer purpose of roller stand to be: the one, can alleviate the weight and the width of roller frame, and improve the rigidity of roller stand; The 2nd, because the narrowed width of roller stand, and be positioned at the contraction in length of the conveying roll shaft of roller stand, thereby improved the rigidity of conveying axis, reduced its processing capacity and processing request; The 3rd, the frame that is used for the backing roll stand narrows down and narrows down with the roller stand, and its rigidity then improves significantly; The 4th, because reduction box is positioned at the outside of roller stand, be not subjected to the influence of roller stand duty, not only stable and reliable for performance, and also easy to maintenance.3, an end of conveying roller by carrying shaft coupling and the universal joint reduction box outer with being positioned at the roller stand to be connected, is three of a feature of the present invention respectively.Adopt universal joint that the purpose of reduction box transmission of power to conveying roller is: the one, can make the transmission fit clearance reach minimum; The 2nd, can adapt to the off normal of reduction box automatically, guarantee effective transmission of power.4, by the adjusting to snub pulley, can finely tune the sanding head and by the sanding amount between sanded board, guarantee the effect of its sanding, many sand head sander then can distribute by the sand amount of cutting of each sanding head of this institutional adjustment in this way.5, two ends of snub pulley adopt worm gear case and chain wheel driving mechanism to control its lifting, are four of features of the present invention.Because the upper end of the elevating screw in this worm gear case is connected with the slip assembly, worm gear case is passed in the lower end and back-moving spring is housed, make the slip assembly be in no gap mated condition with the worm gear case transmission mechanism all the time, guarantee the precision of elevating screw lifting in the handwheel control worm gear case.5, snub pulley adopts belt gear or chain wheel driving mechanism to drive rotation by conveying roller, is five of feature of the present invention.Adopt belt or chain wheel driving mechanism to drive snub pulley and rotate, guaranteed the synchronous rotation between snub pulley and conveying roller, reduced power-driven mechanism.
Technical scheme: sander delivering roller jack horse structure, many conveying rollers are positioned on the axle bed of roller stand, and by carrying shaft coupling and the universal joint reduction box outer with being positioned at the roller stand to be connected, many snub pulleys are distributed between many conveying rollers respectively and drive snub pulley by transmission mechanism by conveying roller and rotate an end of many conveying rollers respectively.The snub pulley two ends are controlled the liter of snub pulley by worm gear case respectively or are fallen.The snub pulley two ends lay respectively in the bearing block, and bearing seat is on the slip assembly, and the elevating screw end is connected with the slip assembly in the worm gear case.Worm gear case is fixed on the below of roller stand, and the elevating screw in the worm gear case is controlled its lifting by worm gear.
The present invention compares with background technology, the one, adopt snub pulley adjustable structure and snub pulley be designed to can monolateral adjustment or both sides adjust the sand amount of the cutting adjustment of both sides when greatly facilitating sand milling, the weak point of having avoided background technology to exist simultaneously; The 2nd, adopt by the cross transmission of carrying shaft coupling and universal joint to constitute and drive delivery roller structure, make fit clearance reach minimum; The 2nd, reduction box is arranged on outside the roller stand, make not only that the roller stand narrows down, weight saving, and improved the rigidity of roller stand, frame and sanding head; The 3rd, improved the convenience and the reliability of maintenance greatly.
