The primary cutter device is characterized in that a driving belt is a synchronous tooth belt with a constant speed ratio; a speed change mechanism adopts a stepless speed change mechanism; a cutting knife arm is arranged through a cantilever with a bevel gear structure, and the transmission rotation shaft of the cutting knife arm is slantways arranged in a cutting transmission case. The utility model with the advantages of stable and precise transmission, etc., can adjust rotation speeds and cooling liquid without shutdown. Glass dust can not splash on slide rails or bearings.
Description
The utility model relates to glass ware forming equipment, is that the hot Glass tubing in a kind of glass tubing drawing machine just cuts device.
The first cutting apparatus of glass tubing tractor is used for the glass-tube cutting of glass tubing production line, and it is disconnected that the hot Glass tubing that it comes out successive towing pursues undercut by the certain-length requirement.The structure of this device and the difference of cutting mode all directly have influence on the cutting quality of glass-tube, as the degree that is uneven, the glass-tube error in length of fracture, and to the suitability of cutting various quality glass-tubes etc.
China is since early fifties begins mechanize production glass-tube product; the thermal ampoule that domestic each glass-tube manufacturer uses just cutting apparatus is continued to use wheel gearing always; cutting mechanism is that excentric shaft adds the dovetail-indent slide block mechanism; obtain the cut lengths of different lengths; must shut down the displacement master of cutting apparatus just; follower gear; this brings inconvenience for the operation of continuity straight-lined manufacturing; and; because the Plane of rotation of cutters is perpendicular to horizontal plane; cooling fluid cognition during the cutting glass-tube is being with the cullet end to splash down on the dovetail slide block mechanism; make this structural maintenance maintenance difficulty, work-ing life is short.There is a kind of glass tubing tractor in Italy, its just the transmission mechanism of cutting apparatus be parallel bands mechanism, the tool arm device of cutters with cantilever that the transmission mechanism follow-up pulley links to each other on, the Plane of rotation of cutters also roughly axially cuts along thermal ampoule perpendicular to horizontal plane.The first cutting apparatus of this structure; though the position of rotation that makes cutters is away from the sliding fast mechanism of dovetail; make and do not have the cullet end and splash down in sliding fast mechanism; but still there is the problem that needs to shut down speed governing; and; can make the fracture range extension along the axial cutting mode of thermal ampoule and reduced the utilization ratio of material that fracture also is uneven.There is a kind of hot glass cutting apparatus just in Japan, is the annular cam plate that the employing level is put, and is a transmission shaft in the middle of the dish, utilizes the height of tool arm on cam plate to rise and fall and the hammering thermal ampoule suddenly during cutting.This hammering mode very easily makes glass-tube burst.
The purpose of this utility model is for a kind of first cutting apparatus of improved Glass tubing tractor is provided; enable under not shutdown situation, to regulate rotating speed; can cutting the thermal ampoule of different diameter, different lengths continuously, and prolonged in the life-span of mechanism, particularly lifting sliding rail.
The first cutting apparatus of Glass tubing tractor comprises transfer gear box, cutting transmission case and cutting arm three partly, and the cutting transmission case is arranged in the lifting dovetail slide rail of transfer gear box one side, and cutting arm is fixedly connected on the output axle head of cutting transmission case.For making transmission accurate, configuration one can reach the synchronous cog belt of constant speed ratio between the input arbor wheel of power output shaft wheel and transfer gear box in the utility model, is with because of this to have teeth groove, and then transmission belt just can not skid.Transfer gear box in the utility model is an infinitely variable transmission that adopts synchronizing jugged chain, this wheel box is in the time will regulating the rotating speed of its output shaft, as long as rotate control hand wheel, make the power wheel that combines with synchronizing jugged chain produce axial displacement and get final product to change its drive diameter.In the utility model, the input shaft end of cutting transmission case and the output axle head of infinitely variable transmission are with the conical gear engaged transmission, thereby can make the output shaft of cutting transmission case become a simple cantilever design, and this output shaft is is inclined to the setting of vertical direction state, cutting arm is fixedly connected on this tilting output axle head, then cutting arm is favouring the plane internal rotation of horizontal direction, is lower-most point when promptly cutters are threaded to the glass-tube position, and the cut direction of cutters is axial perpendicular to thermal ampoule.For necessary cooling fluid of when cutting supply, in another end of tilting output shaft one cooling fluid reservoir is set among the design, and it is connected with cutters with a conduit.
As from the foregoing, the utility model has the advantages that Synchronous Belt Drives makes transmission stable, accurately; The infinitely variable transmission of synchronizing jugged chain enables not adjust rotating speed (that is Cutting Length of adjustment thermal ampoule) with shutting down in continuous production; The cantilever setting of cutting arm and level of incline rotation make cutters away from the dovetail slide rail, and cooling fluid, chopped glass and cutting powder are difficult for splashing to slide rail and are positioned at the bearing place of top turning axle, therefore the work-ing life that can improve parts.The cut direction of cutters is axial perpendicular to thermal ampoule, and then cutting chain is short, can save material.
Description of drawings:
Fig. 1 is a top view of the present utility model.
Fig. 2 is a forward synoptic diagram of the present utility model.
Embodiment of the present utility model as shown in drawings.
See by Fig. 1, present embodiment partly is made up of transfer gear box 1, cutting transmission case 9 and cutting arm 10 3, cutting transmission case 9 is arranged in the vertical dovetail slide rail 12 of transfer gear box 1 one sides, and can make cutting transmission case 9 make cutters 11 on lifting is contained in cutting transmission case 9 lower ends with adjusting the cutting arm 10 and the distance between the Glass tubing in slide rail 12 by control hand wheel 13.See by figure, the stepless speed changing mechanism that comprises transmission gear shift wheel 5,7 and synchronizing jugged chain 6 is housed in the transfer gear box 1, silent chain 6 combines with two ratio gears, 5,7 tensioners, the input shaft of ratio gear 7 stretches out in the gearbox body outside, and belt wheel 2 is housed at its axle head, a synchronizing jugged transmission belt 3 at this belt wheel 2 and 4 tensioners of power output shaft wheel.Stepless speed changing mechanism can make ratio gear move along its axis by 8 controls of handwheel regulating mechanism when rotating this handwheel, then just changed the drive diameter ratio of ratio gear, reaches the purpose of adjusting rotating speed.
See that by Fig. 2 the output shaft of ratio gear 5 is inserted into cutting transmission case 9 in the wheel box 1, and conical gear 16 is housed at its axle head.In the cutting transmission case 9 transmission shaft 18 is housed, dispose the conical gear 17 that is meshed with conical gear 16 therebetween, the lower end installs a cutting arm 10, upper end configuration one reservoir 15 in order to store cooling fluid, and make this reservoir 15 and the cutters 11 that are positioned on the cutting arm are connected with a conduit 14, then cutters 11 constantly have the cooling fluid drip to make the glass-tube brisement on thermal ampoule in cutting thermal ampoule 19 processes.See by figure, transmission shaft 18 is tilting in the cutting transmission case body with respect to vertical direction by two bearings, like this, the cutting arm 10 that is fixed on its lower end rotates in the plane that with respect to the horizontal plane is an inclination angle, when then cutting arm 10 makes cutters 11 go to Glass tubing 19 cut places in rotary course is lower-most point, and this just guarantees can not damage other position of glass-tube 19 of cutters 11.20 is the support roller of support Glass tubing 19 among the figure.
