Description
Technical field
The utility model relates to the process equipment of plastic hollow vessel, relates generally to the driven by servomotor turn device of one-step method full-automatic plastic injection blow blow moulding machine, belongs to the plastics machinery field.
Background technology
With plastics (mainly being meant PE, PP and PC etc.) is raw material, is processed into hollow container (plastic bottle) through annotating to blow, like medicine bottle, bottle for cosmetics and food packaging bottle etc.Existing equipment has one-step method full-automatic plastic injection blow blow moulding machine; This machine is combined bottle base injection moulding and bottle blowing, and injection moulding and blowing are carried out on same workbench, so injection moulding and blow mold are installed on the fixing workbench; Drive three groups of identical plugs by capstan head and insert to injection moulding; Three different stations of the blowing and the demoulding are accomplished, three mutual spacing 120 degree of station, and capstan head is driven by main shaft.The slider crank mechanism that the turn device of prior art adopts hydraulic jack to drive; Major defect is to set when very fast when transposition action; When action puts in place, can cause very big mechanical shock,, influence the operational efficiency of machine so have to be set to less speed operation to transposition action.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art; Frictional force was little when a kind of transposition was provided, and the fast but transposition of speed accurately puts in place again, and mechanical shock is little; Help realizing automation control, the plastic injecting and blowing blow moulding machine driven by servomotor turn device of enhancing productivity.
The technical scheme of the utility model plastic injecting and blowing blow moulding machine driven by servomotor turn device is: comprise the workbench that is installed on the support, capstan head is arranged on the workbench, main shaft is installed in the capstan head; Main shaft is driven by hoist cylinder, and workbench connects the transposition casing down, it is characterized in that installing on the described transposition casing servomotor; The servomotor connection reducer; The output axle head of decelerator connects pinion, and gear wheel is installed on main shaft, and pinion is meshed with gear wheel.
The utility model discloses a kind of plastic injecting and blowing blow moulding machine driven by servomotor turn device, described servomotor connection reducer is after the decelerator deceleration; The output axle head of decelerator connects pinion and gear wheel again, and little tooth is formed the secondary speed-reducing gear pair with gear wheel, after hoist cylinder drives main shaft and capstan head rise and puts in place; The control system sends the transposition action sign on, and servomotor is started working, and the output torque of servomotor amplifies behind decelerator; Rotating speed reduces; Pass through the secondary speed-reducing of gear pair again, further amplification of moment of torsion and rotating speed further are reduced to the actual needs scope of transposition action operating mode, and main shaft is accomplished 120 degree (or 90 degree under the drive of gear wheel; Or 180 degree) rotation and accurately puts in place.This programme adopts servo dynamo-electric the drive, and rotating speed is fast, and the prior art transposition action time needs 1.3 seconds; But adopt the driven by servomotor transposition action only to need to accomplish in 0.7 second; The machine high-speed cruising does not impact but there is machinery, puts in place accurately; Improve the designing requirement of production efficiency, obtained beyond thought effect.Because transposition action is unidirectional all the time, does not have return action, so the inner gear clearance of gap between the large and small gear and decelerator can not have influence on the precision of transposition action.
The plastic injecting and blowing blow moulding machine driven by servomotor turn device of the utility model, described gear wheel is installed on the main shaft through dive key or spline, realizes the moment of torsion transmission through dive key or spline.Described gear wheel is equipped with rolling bearing outward, and rolling bearing has bearing block outward, and bearing block is installed under the workbench, and rolling bearing has been arranged, the low frictional resistance of the positional precision that has guaranteed gear wheel when rotatablely moving.Be equipped with the encoded servo device on the described servomotor; The encoded servo device blows transposition action position closed loop (or semiclosed loop) the control system that blow moulding machine control system forms a closed loop or semiclosed loop with notes; Help realizing automation control, guaranteed accurately putting in place of transposition action.
Description of drawings
Fig. 1 is the plastic injecting and blowing blow moulding machine driven by servomotor turn device structural representation of the utility model.
The specific embodiment
The utility model relates to a kind of notes and blows blow moulding machine driven by servomotor turn device, and is as shown in Figure 1, comprises the workbench 3 that is installed on the support; Capstan head 2 is arranged on the workbench, main shaft 1 is installed in the capstan head 2, main shaft 1 is driven by hoist cylinder 13; Workbench connects transposition casing 43 times; It is characterized in that installing on the described transposition casing 4 servomotor 14, servomotor connection reducer 7, the output axle head 10 of decelerator connects pinion 6; Gear wheel 5 is installed on main shaft 1, and pinion 6 is meshed with gear wheel 5.Described servomotor 14 connection reducers 7 of this programme, after the decelerator deceleration, the output axle head of decelerator 7 connects pinion 6 and gear wheel 5 again; Pinion 6 is formed the secondary speed-reducing gear pairs with gear wheel 5, when hoist cylinder 13 drive main shafts 1 and capstan head 2 rise put in place after, the control system sends the transposition action sign on; Servomotor 14 is started working; The output torque of servomotor amplifies behind decelerator 7, and rotating speed reduces, and passes through the secondary speed-reducing of gear pair again; Further amplification of moment of torsion and rotating speed further are reduced to the actual needs scope of transposition action operating mode; Main shaft is accomplished 120 degree (or 90 degree, or 180 degree) rotation under the drive of gear wheel, and accurately put in place.This programme adopts servo dynamo-electric the drive, and rotating speed is fast, and the prior art transposition action time needs 1.3 seconds; But adopt the driven by servomotor transposition action only to need to accomplish in 0.7 second; The machine high-speed cruising does not impact but there is machinery, puts in place accurately; Improve the designing requirement of production efficiency, obtained beyond thought effect.Because transposition action is unidirectional all the time, does not have return action, so gap between the large and small gear and decelerator 7 inner gear clearances can not have influence on the precision of transposition action.Described gear wheel 5 is installed on the main shaft 1 through dive key 11 or spline, realizes the moment of torsion transmission through dive key or spline.The described gear wheel 5 outer rolling bearings 8 that are equipped with, rolling bearing 8 is outer to have bearing block 9, bearing block 9 to be installed in workbench 3 times, and rolling bearing has been arranged, the low frictional resistance of the positional precision that has guaranteed gear wheel when rotatablely moving.Be equipped with encoded servo device 15 on the described servomotor 14; The encoded servo device blows transposition action position closed loop (or semiclosed loop) the control system that blow moulding machine control system forms a closed loop or semiclosed loop with notes; Guarantee accurately putting in place of transposition action, helped realizing automation control.
