Description

The blank feeding mechanism of plastic heating drawing-blowing machine

Technical field

The utility model relates to the blank feeding mechanism of plastic heating drawing-blowing machine, belongs to the plastics machinery field, is mainly used in to produce mineral water bottle, oil bottle and bottle for cosmetics etc.

Background technology

Adopt and annotate stretch blow production hollow plastic container,, at first plastic raw materials is made bottle base, by heater bottle base is heated again, then by stretch blow machine stretch blow moulding by injection machine as mineral water bottle, oil bottle and bottle for cosmetics etc.Thereby process equipment needs injection machine, heater and stretch blow machine.Described heater and stretch blow machine can be to be divided into independently two equipment, but also can be combined in heater and stretch blow machine on the machine, are called the full-automatic plastic blow moulding machine or are called plastic heating drawing-blowing machine.Plastic heating drawing-blowing machine has a round and round system, plastic bottle blank enters the moulding of stretch blow machine after by the thermal treatment zone in the round and round system, its operation can be divided into blank feeding mechanism, heater, Stretch and Blow Mechanism, moulding bottle output mechanism, and the pushing mechanism that drives the round and round system.The last blank technology of existing plastic heating drawing-blowing machine is a kind of to be to adopt manually to go up base, and the shortcoming of its existence has: the one, and adopt and manually go up base, can be subjected to pollution in one's hands, as making beverage bottle or medicine bottle etc., do not conform to hygienic requirements; The 2nd, need operating personnel specially, labour intensity is big.Another kind is to adopt base on the manipulator, base needs a folder base pliers on the manipulator, pliers at first reaches and obtains bottle base on the feed track, then overturn 180 ° and bottle base is delivered to by the round and round system of plastic heating drawing-blowing machine, stretch out manipulator facing to the bottle base supporting base, then the pressure handle bottle base is pressed onto on the supporting base under the manipulator, and the manipulator of withdrawing again overturns 180 ° again to feed track.Therefore, the shortcoming of its existence: the one, complex structure, one-period need be finished and get base, 180 ° of upsets, top base, 180 ° of actions such as upset again, make, installation, maintenance trouble very all; The 2nd, poor reliability is out of order easily, the cost height; The 3rd, structure is too fat to move, and it is big to take up room, and makes machine irregular.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming that prior art exists, and provides a kind of straight automatically top to combine last base with pressing down, good reliability, and simple structure, installation, maintenance is convenient, uses steadily, the blank feeding mechanism of the plastic heating drawing-blowing machine of life-span length.

The technical scheme of the blank feeding mechanism of the utility model plastic heating drawing-blowing machine is: a frame is arranged, the round and round system of plastic bottle blank is installed on the frame, in the round and round system, blank feeding mechanism is installed, plastic bottle pipe heating device, the marching type pushing mechanism of hollow molding Stretch and Blow Mechanism and drive round and round system, it is characterized in that described blank feeding mechanism is by a minute blanking device, top blanking device and pressed compact device are formed, described minute blanking device is to install to divide the base bracing frame on frame, divide to install on the base bracing frame and divide the base cylinder, tighten branch base movable plate at a minute base cylinder piston rod, divide on the base movable plate and fix two fens oralia fixed heads, two fens oralias are installed on two fens oralia fixed heads, oralia was shaped on the bottle base groove in two minutes, two fens oralia fronts are briquets into, advance briquet and are fixed on the branch base gripper shoe; Described top blanking device is that top base frame base plate is installed on frame, four top base support columns are installed on the base frame base plate of top, base support column top, top is top base frame upper plate fixedly, top base cylinder is fixed on top base frame upper plate downside, top base cylinder piston rod connects top blank plate, and two bottle base bases are arranged on the top blank plate, and the bottom connection of bottle base base and plastic bottle blank touches, be the bottle base seat directly over the bottle base base, bottle base seat inner core contacts with the plastic bottle blank oral area.

The blank feeding mechanism of the utility model plastic heating drawing-blowing machine, adopt three cylinders to finish branch base, top base and three functions of pressed compact, simple in structure, installation, maintenance is convenient, divide the base cylinder to realize that one goes out two, i.e. two bottles of a machine disposal molding, top base cylinder makes bottle base forward on the bottle base guide rail of round and round system from following base mechanism, the pressed compact cylinder tightly is enclosed within on the bottle base seat bottle base, and everything is finished automatically by machine, need not manual operations, the liberation labour, save man-hour, and avoid staff directly to contact, reduce and pollute with bottle base.It adopts manipulator to compare with tradition, simple in structure, action accurately fast, divide the base cylinder to make to be clipped in two bottle bases that advance in the briquet and enter respectively in two bottle base grooves of two fens oralias, and navigate on the bottle base base of top blank plate, top base cylinder is up delivered to the bottle base seat with two bottle bases, and branch base cylinder and top base cylinder utilize the remaining space between round and round system and the frame, rationally distributed, compact conformation.

The blank feeding mechanism of the utility model plastic heating drawing-blowing machine, its described pressed compact device is mounted in the pressed compact frame fixed head on the round and round system frame, two pressed compact frame support columns are installed on the pressed compact frame fixed head, pressed compact frame support column top is the pressed compact air cylinder fixed plate fixedly, the pressed compact cylinder is fixed on above the pressed compact air cylinder fixed plate, pressed compact air cylinder fixed plate opposite side is installed two pressed compact plate guide pillars, pressed compact plate guide pillar lower end connects the pressed compact plate, the connection of pressed compact plate compresses pipe, compressing under the pipe is the bottle base seat, compresses pipe and contacts with bottle base seat inner core.The pressed compact cylinder makes and compresses pipe and press down bottle base seat inner core, thereby makes the bottle base seat tightly block bottle base, does not cause it to drop in the round and round system.Top base yielding rubber is housed on its described top blank plate, prevents that top base cylinder piston rod from stretching out too fast or cross the position and the bottle base mouth is clashed into mutually with the bottle base seat, the minimizing impulsive force.
