Band sawing machine saw blade slewing equipment
Technical field
The utility model relates to a kind of band sawing machine saw blade slewing equipment, belongs to the manufacturing technology field of building mechanical equipment.
Background technology
At present; speed of production, the efficient of advanced both at home and abroad polyurethane, rock wool, polystyrene battenboard tinuous production are more and more higher; and the cuts sheet material equipment that it adopts---band sawing machine becomes the bottleneck that production line improves speed of production, efficient; the function of band sawing machine mainly is under the non-stop-machine prerequisite of production line, and the finished product sheet material of continuous output is cut automatically.Existing band sawing machine mainly is made of base, saw blade, workbench, dust exhaust apparatus etc., when having cut a sheet material, because the saw blade sawtooth is only in a side, can not reverse cut, when cutting second block of sheet material, can only return initial position earlier fast, cut again, influenced production efficiency.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, and is simple in structure, reliable operation, economical and practical band sawing machine saw blade slewing equipment.
The utility model is a band sawing machine saw blade slewing equipment, comprise with the base of going up mount pad and following mount pad, place the saw blade between mount pad and the following mount pad, it is characterized in that being equipped with on mount pad and the following mount pad rotary drive mechanism of band driving gear, the overturning seat of band driven gear; Driving gear and driven gear engaged transmission, saw blade place in the overturning seat on mount pad and the following mount pad.
Also can be provided with directive wheel on the described overturning seat, saw blade places between the directive wheel.
Described going up on the mount pad also can be provided with sweep-up pipe.
Described rotary drive mechanism can be cylinder or motor.
The utility model adopts up and down two rotary drive mechanisms to drive the engaged transmission of driving gear and driven gear, make two overturning seats drive saw blade and finish 180 ° of rotations synchronously, reasonable in design, guaranteed the saw blade flip angle, make the band sawing machine can reverse cut sheet material, thereby improved the service efficiency of band sawing machine, one of band sawing machine comes resilience cutting two boards material, about production efficiency doubles, improved speed of production greatly, and move simple and reliable, accurate positioning, make the sheet material cutting smooth, rapidly and efficiently.The utility model can be applicable on polyurethane, rock wool, the polystyrene battenboard tinuous production.

The specific embodiment
The utility model is mainly by the base 10 with last mount pad 5 and following mount pad 7, place the overturning seat 9 of rotary drive mechanism 2, band driven gear 4 and the directive wheel 8 of band driving gear 3 on mount pad 5 and the following mount pad 7 respectively, place the saw blade 6 between the directive wheel 8, place sweep-up pipe 1 formation such as grade on the mount pad 5; Driving gear 3 and driven gear 4 engaged transmission.Rotary drive mechanism 2 is cylinder or motor.
During the band sawing machine cuts sheet material, saw blade 6 fast rotational are advanced, after having cut a sheet material, saw blade 6 stops, rotary drive mechanism 2 drives driving gear 3 and does 180 ° of rotations, make overturning seat 9 also do 180 ° of rotations by engaged transmission, do 180 ° of upsets thereby make the directive wheel 8 that is installed on the overturning seat 9 drive saw blade 6 with driven gear 4.After the upset, band sawing machine drives the saw blade slewing equipment and retreats by sweep-up pipe 1, base 10, saw blade 6 fast rotational and cuts sheet material, and sweep-up pipe 1 absorbs part dust, powder, the iron filings that cutting produces, and the performance of lathe is guaranteed.
