The laser cutting machine feed arrangement
Technical field
The utility model relates to a kind of laser cutting device, relates in particular to the feed arrangement of laser cutting machine.
Background technology
Laser cutting machine is widely used in cutting metal, cloth, cladding, acrylic board, electronic circuit board etc.The feed arrangement of conventional laser cutting machine is made of frame, longeron, active roll tube, tensioning roller, metal mesh belt and hood etc., two longerons that are parallel to each other are installed at top in frame, hood is installed in the top of longeron, in case the cutting flue gas leaks the infringement workers ' health.Active roll tube is positioned at the afterbody of frame, and the two ends of active roll tube are bearing on two longerons by bearing.The tensioning roller be positioned at frame front portion, hood front end under, the two ends of tensioning roller also are bearing on two longerons by bearing, and are connected by metal mesh belt between tensioning roller and the active roll tube.Above structure does not have feeding platform, and material to be processed is directly sent in the hood by the space between hood front end and the metal mesh belt and processed, and some material to be processed can be wrinkling in the process of transporting, thereby influence crudy.Add labor and materials and flatten, not only very inconvenient, and can waste a large amount of process times, reduce working (machining) efficiency.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of feeding laser cutting machine feed arrangement easily.
The technical solution of the utility model is as follows: a kind of laser cutting machine feed arrangement, comprise frame, longeron, active roll tube, the tensioning roller, metal mesh belt and hood, wherein hood is installed on the top of frame, two longerons that are parallel to each other are set at the top of frame, the front end of two longerons is by bearing supporting tensioning roller, the tail end of two longerons supports active roll tube by bearing, be connected by metal mesh belt between active roll tube and the tensioning roller, its key is: described tensioning roller is positioned at the place ahead of hood, and one section metal mesh belt between tensioning roller top and the hood front end face bottom forms feeding platform.
The utility model prolongs the frame front end on the basis of traditional structure, the installation site reach of tensioning roller, make one section metal mesh belt in hood the place ahead form feeding platform, material to be processed is placed on this feeding platform, when rotating under the drive of active roll tube at motor, the metal mesh belt running, material to be processed moves with metal mesh belt, is admitted in the hood and processes.Feeding platform works to be convenient to feeding on the one hand, on the other hand, also can will send in the hood again after the material flattening to be processed on feeding platform, not only flatten simple to operate, save a large amount of process times, effectively improved working (machining) efficiency, and ensured the quality of processing.
The binder roller is housed above above-mentioned feeding platform, and this binder roller parallels with the tensioning roller.The binder roller is as the servo-actuated roller, and support by bearing at two ends, and self is drive not.The binder roller cooperates with metal mesh belt, and the material to be processed after flattening is sent in the hood, can further guarantee the planarization of material to be processed.
Beneficial effect: the utlity model has be skillfully constructed, simple in structure, implement characteristics such as easy, it can make things convenient for feeding and flatten operation, has both saved process time, has improved working (machining) efficiency, has ensured the quality of processing again.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 removes the stereogram of hood and binder roller for the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, hood 6 is installed on the top of frame 1, two longerons 2 that distribute along frame 1 length direction are set at the top of frame 1, two longerons 2 are parallel to each other, the end face upper mounting rail 9 of each longeron 2, guide rail 9 distributes along longeron 2, and together support crossbeam 10 on two guide rails 9, and crossbeam 10 can slippage on guide rail 9.Active roll tube 3 is positioned at the tail end at frame 1 top, the two ends of active roll tube 3 are bearing on two longerons 2 by bearing, and active roll tube 3 is perpendicular with longeron 2, and the driven sprocket on the active roll tube 3 is connected with drive sprocket on reducing motor 11 output shafts by chain.Tensioning roller 4 is positioned at the front end at frame 1 top, and the two ends of tensioning roller 4 are bearing on two longerons 2 by bearing, and tensioning roller 4 is also perpendicular with longeron 2, is connected by metal mesh belt 5 between tensioning roller 4 and the active roll tube 3.In metal mesh belt 5 formed runway shape ring belt areas, be provided with many carrying rollers 12, carrying roller 12 distributes along longeron 2 length directions, the two ends of each carrying roller 12 are bearing on two longerons 2 by bearing, and carrying roller 12 is held the top of metal mesh belt 5, and can rotate with the running of metal mesh belt 5.
From Fig. 1 further as can be known, described tensioning roller 4 is in the place ahead of hood 6, one section metal mesh belt 5 between tensioning roller 4 tops and the hood 6 front end faces bottom forms feeding platform 7, and binder roller 8 is housed above this feeding platform 7, and this binder roller 8 parallels with tensioning roller 4.
In the utility model, material to be processed is placed on the feeding platform 7 and flattens, reducing motor 11 runnings, reducing motor 11 drives active roll tube 3 rotations by chain and sprocket wheel, make metal mesh belt 5 do clockwise running around active roll tube 3 and tensioning roller 4, material to be processed is with metal mesh belt 5 motions, and assisting down of binder roller 8, material to be processed is admitted in the hood 6 and processes.Made things convenient for feeding and flattened operation with upper type, not only saved process time, improved working (machining) efficiency, and can ensure the quality of processing.
