Description
Technical field
The present invention relates to plastic hollow vessel moulding stretch blow machine, particularly relate to plastic hollow make-up machine template power-assist travelling mechanism, be mainly used in all kinds of hollow plastic containers such as processing mineral water bottle, oil bottle, belong to the plastics machinery field.
Background technology
At the processing mineral water bottle, during all kinds of hollow plastic container such as oil bottle, can manage heating system to bottle is in the same place with the stretch blow system in combination, the travelling mechanism that a conveying plastic bottle tube is arranged, after the plastic bottle-pipe heating, can send into automatically and make the moulding bottle in the stretch blow system, because the stretch blow system need finish folding mould and two stages of stretch blow, so advancing of travelling mechanism is interrupted, the existing power that drives travelling mechanism adopts stepper motor to drive or cylinder promotes two types, the main structure that described stepper motor drives is mounted in two chains on the sprocket wheel, one of them sprocket wheel is driven by stepper motor, hang bottle piping support seat conveying plastic bottle tube on the chain, the shortcoming of this technical scheme is that the stroke of stepper motor drive on the one hand exists error, and in a single day the position that plastic bottle-pipe enters the stretch blow mould has deviation will make product rejection; Stepper motor and supporting control damage easily on the other hand, maintenance, debugging trouble, and influence is produced.It also is two sprocket wheels and a chain that described cylinder promotes, bottle piping support seat is installed on the chain, but two sprocket wheels do not rotate, but rely on rack-mounted manipulator to drive, manipulator has a slide rail and 2 or 3 cylinders, the parallel installation of slide rail with chain, it is to become 90 ° of directions to drive shift fork with chain that a shift fork cylinder is arranged on the slide rail, another promotes the end drive shift fork cylinder that cylinder is positioned on slide rail, the shift fork cylinder promotes shift fork during work, shift fork inserts in the chain and contacts with the chain pin, then promoting cylinder promotes the shift fork cylinder and chain was pushed away a segment distance, plastic bottle-pipe is just in time sent in the mould, and then shift fork cylinder drive shift fork withdraws from from chain, promotes cylinder and gets back to original position, error appears in the distance of advancing for fear of chain, the 3rd positioning cylinder can be installed on frame, and positioning cylinder drive location fork inserts in the chain, and the distance that chain advances is at every turn located.Therefore, the shortcoming that existing cylinder promotion technology exists is: the one, and complex structure needs 2 or 3 cylinders, cost height, installation, debugging, maintenance trouble; The 2nd, operating error is many, because each cylinder entirely on frame, cooperates difficulty big with the stretch blow mould of motion, control system requires height; The 3rd, the manipulator of many cylinders of installation on the limit of frame increases machine volume, and external form is irregular, influences attractive in appearance.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art, provide a kind of and promote plastic bottle-pipe advances on the chain travelling mechanism and stretch blow mould and work good, simple in structure, cost is low, installs, debugs plastic hollow make-up machine template power-assist travelling mechanism easily.
The technical scheme of plastic hollow make-up machine template power-assist travelling mechanism of the present invention is: comprise frame; rack-mounted plastic bottle-pipe heating system and stretch blow system; described heating system comprises the sprocket wheel of two Plane Installation and the chain that matches; drive the power of chain operation; and heated holder and heating member; bottle piping support seat is installed on the chain; described stretch blow system comprises front template; middle template and rear pattern plate; drive the clasp mould mechanism of template; and Stretch and Blow Mechanism, the power that it is characterized in that driving the chain operation has on the outer wall of front template installs a slide rail and a side mounting plate, installs on the fixed head and promotes cylinder; the slide block that matches is arranged on the slide rail; slide block connects shift fork, and the piston rod that promotes cylinder drives slide block and shift fork, and the head of shift fork contacts with the pin of chain.
Plastic hollow make-up machine template power-assist travelling mechanism of the present invention, whole service mechanism is installed on the front template, makes the compact conformation of complete machine, and volume is little; Folding by the stretch blow mould realizes the transverse movement of shift fork, saves a lateral cylinder thus, reduce cost, and the motion of stretch blow mould directly controls shift fork, makes operation accuracy rate height, no time error, installation, debugging, easy to maintenance; Motion by cylinder realizes the lengthwise movement of shift fork, and stroke because power-assist mechanism is positioned at the chain inboard, makes complete machine neat, good looking appearance again by the cylinder cavity length control of cylinder.During die sinking, front template moves right, the shift fork that drives slide block and be connected with it moves right, shift fork inserts the space between the chain and contacts with pin, promoting cylinder this moment starts, stretch out piston rod, the slide block that is connected with piston rod is slided in slide rail, when piston rod all stretched out, slide block slided into the slide rail terminal, and shift fork drives chain and is installed in bottle piping support seat on the chain move one or two or the distance of bottle piping support seat more than two, distance is relevant with the stretch blow Mould design, if one goes out one stretch blow mould, then move the distance of a bottle piping support seat, if one goes out two stretch blow mould, then move the distance of two bottle piping support seats, stretch blow this moment mould matched moulds, front template drives shift fork by slide block and withdraws from chain, and matched moulds finishes, the stretch blow mould carries out the stretch blow moulding, cylinder resets simultaneously, and piston rod and slide block are all got back to original position, so that carry out the stepwise operation of next round.
Plastic hollow make-up machine template power-assist travelling mechanism of the present invention, the affixed connecting plate of its slide block by connecting plate affixed piston rod of difference and shift fork, fixes connection slide block, piston rod and shift fork by connecting plate, makes to be connected firmly that transferring power is reliable.Its connecting plate fixes by screw or pin and shift fork.On its connecting plate adjustment screw is installed, adjustment screw contacts with fixed head, because when connecting plate is installed, the deviation that the installation site may occur, collision chain pin when causing being fixed in shift fork on the connecting plate and moving laterally between the chain link, after adjustment screw has been arranged, can fast, accurately adjust to rational position.The head of its shift fork is the single tine head, and the chain pin has sleeve pipe outward, and the single tine head contacts with sleeve pipe, and the single tine header structure is simple, and is easily manufactured, and mounting sleeve outside the chain pin makes the single tine head contact with sleeve pipe, can prevent that the pin of the inside is impaired.Its slide block is shaped on dovetail groove, and dovetail groove matches with slide rail, adopts dovetail groove can prevent that limited slip block breaks away from slide rail, makes slide block stable.
