Abstract
The utility model provides a spiral driving mechanism of a tension bar of a plastic bottle-blower. The mechanism comprises a frame, and a power device mounted on the frame drives the tension bar. The mechanism is characterized in that the power device comprises a servo motor mounted on the frame; the servo motor drives a ball screw through a decelerating mechanism; a ball screw sleeve matched with the ball screw is mounted outside the ball screw; the ball screw sleeve drives a connecting plate; the tension bar is mounted below the connecting plate; guide rails are arranged on the two sides of the frame; and two head parts of the connecting plate are contact with the guide rails. Compared with the prior art, the mechanism has the advantages of high reliability, steady operation, high speed and long service life; the servo motor and the like are convenient to mount; and a control system is simple and easy to debug and maintain.
Description
Technical field
The utility model relates to the spiral lead agency of blower for plastic bottle stretching bar, 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 be by drawing mechanism and the stretch blow moulding of blowing mechanism, described drawing mechanism mainly comprises the stretching bar, drive the power and the frame of stretching bar, the power that prior art drives the stretching bar is cylinder, and by the piston rod drive connecting plate of cylinder, connecting plate is installed the stretching bar down.The shortcoming that is driven the stretching bar by cylinder is: one, the speed of service is slow: the inlet and outlet in the cylinder are subjected to control structure complexity such as gas circuit and magnetic valve, and intermediate link is many, and speed is slow, and efficient is low; Two, poor reliability: the piston of cylinder weares and teares easily.Gas circuit and valve damage easily, often will keep in repair, poor stability in service; Three, the controlling organization complexity of cylinder gas circuit distributor makes trouble.
Summary of the invention
The purpose of this utility model 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 the bar of blower for plastic bottle stretching stably.
The technical scheme of the spiral lead agency of the utility model blower for plastic bottle stretching bar is: comprise frame, power is installed on frame, power drives the stretching bar, it is characterized in that described power comprises rack-mounted servomotor, servomotor drives ball screw through reducing gear, the ball silk braid is installed outside ball screw, the ball silk braid matches with ball screw, the ball silk braid drives connecting plate, connecting plate is installed the stretching bar down, there is guide rail the both sides of frame, and two heads of connecting plate contact with guide rail.
The utility model discloses the spiral lead agency of a kind of blower for plastic bottle stretching bar, driving ball screw after adopting servomotor to slow down through reducing gear rotates, the ball screw rotation drives the motion up and down of ball wire cover, the stretching bar 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 control system is simple, and debugging, maintenance are easily.
The spiral lead agency of the utility model blower for plastic bottle stretching bar is installed bearing block and step on the described 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 stretching bars in the described 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 described connecting plate, connecting plate contacts with guide rail by 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 described frame, servomotor and reducing gear fix by fixed head and frame.Servomotor and reducing gear are installed in easy accessibility on the fixed head, and be fixed.
