Description

The full automatic plastic bottle pipe heater

Technical field

The utility model relates to plastic bottle pipe heater, is the equipment that two-step method is produced plastic hollow vessel, for example is used to produce mineral water bottle, oil bottle etc.

Background technology

With plastics is raw material, adopt notes, stretch blow to produce hollow containers such as various beverage bottles, oil bottle, usually use the processing technology of two-step method, promptly at first produce the bottle pipe by injection machine, then the bottle pipe is heated by heater, by the stretch blow machine bottle pipe after heating is carried out the stretch blow moulding again, in the middle of this, need plastic bottle pipe heater.Existing plastic bottle pipe heater kind is a lot, generally can be divided into fixed or rotary type, described fixed heater is a baking oven, by manually the bottle pipe being put into heater, by artificial taking-up, its shortcoming is an inefficiency after heating, and labour intensity is big, summer is awfully hot, and operating personnel are very arduous.The rotary type heater has manually-operated and manipulator to fetch and deliver two kinds, the greatest drawback of existing rotary type plastic bottle pipe heater is that the bearing assembly of delivery bottle pipe is to be fixed on rotating link chain one side, upper and lower not liftable, therefore, only make the employing manipulator also can't carry out translation and change rail, must transmit by the mode of upset, so exist the complex structure of manipulator, need special-purpose power, for example comprise upper and lower elevating mechanism, forward and backward telescoping mechanism, stand up rotating mechanism etc., control is complicated, the volume heaviness, the assembling trouble, the expense height.On the other hand owing to can not translation change rail, have only for the equipment of many of stretch blows heater to be made very long, it is very big to take up an area of the space.

Summary of the invention

The purpose of this utility model provides a kind of upper and lower liftable of bearing assembly that delivers bottle pipe, make that bottle pipe is realized being input into, output or translation change rail, the track of heater can design arbitrarily, and it is reasonable to take the workshop, and reaches mechanically operated full automatic plastic bottle pipe heater fully.

The technical scheme of the utility model full automatic plastic bottle pipe heater is: a frame is arranged, the annular delivery track of being made up of the sprocket wheel and the driving chain of power drive is installed in the frame, one side of annular delivery track connects feeding mechanism, opposite side connects adjacent track or discharging mechanism, discharging mechanism connects the stretch blow unit, heating tube is installed in delivery track, the bearing assembly of delivery bottle pipe is installed in a side of driving chain, the bearing assembly that it is characterized in that described delivery bottle pipe is the sleeve pipe that is connected driving chain, the lifting cramp bar is installed in the sleeve pipe, cramp bar top connects guide rail or from rotary chain wheel, guide rail or the lifting groove is arranged under rotary chain wheel, the slope cam is installed on the heater frame, the slope cam matches with the lifting groove, in the bottom of cramp bar mounting spring, plastic bottle-pipe grafting joint is arranged in the next top of cramp bar, the push pipe cam is installed on the adjacent delivery track lower framework of feeding mechanism.

The utility model full automatic plastic bottle pipe heater, before plastic bottle-pipe is shifted delivery track from feed channel onto by the material toggling index dial, the position of plastic bottle-pipe is lower than the grafting joint, the push pipe cam that dependence is installed under the frame upwards is socketed on the grafting joint bottleneck in the top bottle pipe, is then driven along with delivery track operation heating by cramp bar; Other method is before plastic bottle-pipe is shifted delivery track from feed channel onto by the material toggling index dial, the position of plastic bottle-pipe is consistent with delivery track, the cramp bar that will be connected with the grafting joint in this position raises, cramp bar is descended insert the plastic bottle mouth of pipe by the grafting joint, with push pipe cam synergy, drive along with delivery track operation heating by cramp bar again.When the plastic bottle-pipe after the heating need be sent into the stretch blow unit or run to another adjacent annular delivery track, the so-called position that changes rail, the slope protruding rail is installed on frame, when the lifting groove on the cramp bar and slope protruding rail slide, cramp bar rises, extract from the grafting joint or from the plastic bottle mouth of pipe cramp bar bottom, plastic bottle-pipe makes last to enter slideway under one the pushing together with grafting joint or simple plastic bottle-pipe in the back, perhaps by the material toggling index dial it is sent into slideway.So this heater is because the upper and lower liftable of cramp bar in the bearing assembly of delivery bottle pipe, make the bottle pipe realize that translation changes rail, structure is very simple, and the track of heater can design arbitrarily, it is reasonable to take the workshop, and (comprises feeding, changes rail and discharging) in whole service and automatically finish.

Its plastic bottle-pipe grafting joint of the utility model and cramp bar can be consubstantiality joint (being made into integration) or the allosome joint (two bodies link to each other) that is connected, are good in the allosome mode that links to each other in use.The mouth of pipe is firm is connected with bottle in order to make the grafting joint, is shaped on draw-in groove on the grafting joint, and tensioning spring is installed in the draw-in groove, manages an internal orifice by tensioning spring and bottle and cooperates.In order to operate steadily, the grafting joint of its allosome connects supporting plate.For charging can be carried out at grade smoothly, bottle pipe feed channel and material toggling index dial are installed on feeding mechanism.The described annular delivery track of this heater is more than one group or one group, and for example two groups, three groups or more groups, each is organized between the adjacent track or in the discharging mechanism slideway is installed, and the multiple road can avoid length long, and minimizing takes up room, and shortens the workshop.Its described slope cam mainly is mounted on the frame of closely facing material toggling index dial and slideway.The slope protruding rail matches with the lifting groove cramp bar bottom is raise, and makes joint insert in the bottle mouth of pipe or extracts from the bottle mouth of pipe.If cramp bar and grafting joint allosome, the grafting joint can change its course or enters the stretch blow unit along with plastic bottle-pipe, only cramp bar is extracted to get final product from the grafting joint.In order to realize all that automatically its stretch blow unit connects the discharging slideway, the discharging slideway pulls out the material index dial.
