Abstract
The invention discloses a screw type driving mechanism for a stretch rod of a plastic bottle blowing machine. The screw type driving mechanism comprises a stand, wherein power is arranged on the stand and is used for driving the stretch rod. The screw type driving mechanism is characterized in that the power comprises a servo motor arranged on the stand and drives a ball screw through a reducing mechanism; a ball screw sleeve is arranged outside the ball screw and is matched with the ball screw; the ball screw sleeve drives a connecting plate; the stretch rod is arranged below the connecting plate; guide rails are arranged at two sides of the stand; and two head parts of the connecting plate are in contact with the guide rails. Compared with the prior part, the invention has the advantages of high work reliability, stability for operation, high speed, long service life, convenience for installation of the servo motor and the like, simpleness for a control system and easiness for debugging and maintaining.
Description
Technical field
A kind of spiral lead agency of blower for plastic bottle stretch that relates to of the present invention belongs to the plastics machinery field.
Background technology
Blower for plastic bottle (or claiming plastic container forming machine) is in the process of processing plastic container; After heated bottle embryo is sent into mould, need through drawing mechanism and the stretch blow moulding of blowing mechanism, described drawing mechanism mainly comprises stretch; Drive the power and the frame of stretch; The power that prior art drives stretch is cylinder, and by the piston rod drive connecting plate of cylinder, connecting plate is installed stretch down.The shortcoming that is driven stretch by cylinder is: one, the speed of service is slow: the inlet and outlet in the cylinder receive control structures such as gas circuit and magnetic valve complicated, and intermediate link is many, and speed is slow, and efficient is low; Two, poor reliability: the piston easy abrasion of cylinder.Gas circuit and valve damage easily, often will keep in repair, poor stability in service; Three, the controlling organization of cylinder gas circuit distributor is complicated, makes trouble.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming that prior art exists, provide a kind of power lead agency simple, be not easy to damage speed of service piece, the spiral lead agency of blower for plastic bottle stretch stably.
The technical scheme of the spiral lead agency of blower for plastic bottle stretch of the present invention is: comprise frame, power is installed on frame, power drives stretch; It is characterized in that described power comprises rack-mounted servomotor; Servomotor drives ball screw through reducing gear, and the ball silk braid is installed outside ball screw, and the ball silk braid matches with ball screw; The ball silk braid drives connecting plate; Connecting plate is installed stretch down, and there is guide rail the both sides of frame, and two heads of connecting plate contact with guide rail.
The invention discloses the spiral lead agency of a kind of blower for plastic bottle stretch; Drive ball screw after adopting servomotor to slow down through reducing gear and rotate, the ball screw rotation drives ball wire and overlaps motion up and down, and the stretch that the ball silk braid drives under the connecting plate is a kind of machine driving; Compare with actuating units such as cylinder, gas circuits: have the functional reliability height; Operate steadily, speed is fast, long service life; Servomotors etc. are easy for installation, and the control system is simple, and debugging, maintenance are easily.
The spiral lead agency of blower for plastic bottle stretch of the present invention is installed bearing block and step on the said frame, bearing is installed in upper and lower bearing block separately, and ball screw passes upper and lower bearing block and matches with bearing.Ball screw is installed in the upper and lower bearing block and connects firmly, has had bearing that ball screw is rotated easily.Be equipped with 1,2,4,8 or 12 stretch in the said connecting plate, be suitable for various one and go out the multimode bottle mechanism, many plastic containers of time processing.Two head mounting guide rail slide blocks of said connecting plate, connecting plate contacts with guide rail through the guide rail slide block.Had the guide rail slide block to contact with guide rail, connecting plate is slided on guide rail easily, frictional resistance is little.Mounting plate on the said frame, servomotor and reducing gear fix through fixed head and frame.Servomotor and reducing gear are installed in easy accessibility on the fixed head, and be fixed.
Description of drawings
Fig. 1 is the spiral lead agency schematic perspective view of blower for plastic bottle stretch of the present invention;
Fig. 2 is that the spiral lead agency master of blower for plastic bottle stretch of the present invention looks sketch map.
The specific embodiment
The present invention relates to the spiral lead agency of a kind of blower for plastic bottle stretch,, comprise frame like Fig. 1, shown in Figure 2; Power is installed on frame, and power drives stretch, it is characterized in that described power comprises the servomotor 2 that is installed on the frame 1; Servomotor drives ball screw 4 through reducing gear 3, and ball silk braid 5 is installed outside ball screw 4, and the ball silk braid matches with ball screw 4; Ball silk braid 5 drives connecting plate 6; Connecting plate is installed stretch 76 times, and there is guide rail 11 both sides of frame 1, and two heads of connecting plate 6 contact with guide rail 11.Driving ball screw 4 after this programme adopts servomotor 2 to slow down through reducing gear 3 rotates; Ball screw 4 rotations drive ball wire cover 5 and move up and down; The stretch 7 that ball silk braid 5 drives under the connecting plate 6 is a kind of machine driving, compares with actuating units such as cylinder, gas circuits: have the functional reliability height, operate steadily; Speed is fast, long service life; Servomotors etc. are easy for installation, and the control system is simple, and debugging, maintenance are easily.Install bearing block 12 and step 13 on the said frame 1, bearing 14 is installed in upper and lower bearing block separately, ball screw 4 passes upper and lower bearing block 12,13 and matches with bearing 14.Ball screw is installed in the upper and lower bearing block and connects firmly, has had bearing that ball screw is rotated easily.Be equipped with 1,2,4,8 or 12 stretch 7 in the said connecting plate 6, be suitable for various one and go out the multimode bottle mechanism, many plastic containers of time processing.Two head mounting guide rail slide blocks 61 of said connecting plate 6, connecting plate 6 contacts with guide rail 11 through guide rail slide block 61.Had the guide rail slide block to contact with guide rail, connecting plate is slided on guide rail easily, frictional resistance is little.Mounting plate 15 on the said frame 1, servomotor 2 fixes through fixed head and frame with reducing gear 3.Servomotor and reducing gear are installed in easy accessibility on the fixed head, and be fixed.
