Abstract
The invention relates to an adjusting apparatus for, pins for the processing of rubber, thermoplastic plastics, pins for the dehydration of water resistant compound material, or pins extruded by a screw extruder. Pins which are able to respectively be extruded radially from the cavity of the screw extruder are connected with a piston pole by screws. By operating a closing valve, the pistons in the hydrocyliner can move individually or in group, therefore the pins can be extruded from or inserted to the cavity of the screw extruder within seconds.
Description
The invention relates to the pin adjusting device of the pin type of screw arbor extruder of a kind of processing rubber, thermoplastic and analog.
United States Patent (USP) 4,178,104 disclose a kind of pin adjusting device of pin type of screw arbor extruder.
The pin of this adjusting device and slide block be with being threaded, and with lock nut locking, makes pin be connected with slide block and can not rotate.Move radially in the guide rail of slide block on the screw extruder barrel.The ring gear of an adjustment usefulness, its side relative with slide block is a curved surface, corresponding inverse surface mutually cooperates on this curved surface and the slide block.Ring gear drives with a pinion.Free to rotate and the available retaining ring of ring gear of band curved surface is fixed.
United States Patent (USP) 4,178,104 described pin adjusting devices have many shortcomings.
At first, ring gear must be enclosed within on the screw extruder barrel.Ring gear is bearing on the sleeve-shaped guide on its terminal position, and guide rail must screw with the screw extruder barrel.At last, the side of ring gear and adjustment slide block is the adjustment curved surface of precision-fit, and the machining of these parts is very expensive.
And the supporting of the adjustment pinion that is meshed with ring gear on the screw extruder barrel requires a very expensive structure.Can confirm to make this adjusting device expense costliness.
And the assembling of this adjusting device is also very difficult.The barrel bamp joint is welded in before the barrel Duan Yiduan, and the cover tubular guide rail sleeve that must will lay the ring gear bearing is on barrel.Then ring gear is enclosed within on the barrel, is installed to preposition.Guide rail could be screwed on extruder barrel subsequently.Then the side is had the precalculated position of the slide block set of curved surface at extruder barrel, each pin is by being threaded into slide block.After the adjusting device assembling finishes, a barrel flange is welded on the barrel section.
If the song of slide block or ring gear side is to the wearing and tearing that occur to a certain degree, the almost interchangeable new barrel section of the expense that the dismounting of these parts will be changed.Not only screw rod must be pulled out from extruder, also the barrel bamp joint will be taken apart, weld lower flange then.
Take these measures to cause screw extruder long especially downtime, this is unallowable.
The objective of the invention is to design a kind of pin adjusting device, require it simple in structure, be easy to assembling and dismounting.Particularly when repairing adjusting device, must avoid pulling out the screw rod of screw extruder and the flange that must avoid taking apart and welding down each barrel section.
The task of invention has solved with the described feature of claim characteristic.Pin adjusting device of the present invention, has a rotating screw rod in extruder cylinder, around material tube inner wall and on the axial direction, approximately equidistantly distribute and also radially extend, point to the pin of the screw rod longitudinal axis, insert the cut screw flight in barrel place at pin, and an adjusting device that is used to adjust the pin insertion depth, it is characterized in that, pin is made up of the piston rod of hydraulic cylinder, and hydraulic cylinder is fixed on the extruder cylinder.Mark is guided and be carved with to the other end facing to piston rod effect end axially by hydraulic cylinder.
The wall bar of living is used as the pin that inserts the extruder inner chamber simultaneously makes the key pin very simple and efficient.Only need make the piston rod of each hydraulic cylinder enter or come out, just can change the insertion depth of pin.
Because be fixed on all hydraulic cylinder concurrently-acting on the screw extruder barrel, perhaps in each sagittal plane in all pins or each the screw extruder cross section all pins removable, in the barrel section, will produce different stress to certain viscosity of a certain temperature or material to be machined.
In order to do cleaning or similarly work, in the time of need pulling out screw rod, in seconds pin can be pulled out from the screw extruder inner chamber, so just can pull out screw rod.
Another kind of structure of the present invention is (perhaps just opposite) in the piston that is threaded into hydraulic cylinder of pin.
One embodiment of the present of invention as shown in the figure.
The longitudinal sectional drawing of Fig. 1 extruder barrel section,
Fig. 2 is II-II transverse cross-sectional view of Fig. 1.
Screw rod 2 rotates in screw extruder barrel 1, by screw thread 3 convey materials.Spirality screw flight 3 inserts screw extruder inner chamber 5 places at pin 4 and cuts off.
Pin 4 is that the piston rod by hydraulic cylinder 6 constitutes.
According to the purposes of machine, whole hydraulic cylinders 6 controlled by available stop valve or grouping is controlled.
Can in seconds pin 4 be moved from screw extruder inner chamber 5 as long as operate the stop valve of this pattern very simply, just can reach the purpose that makes machine can be used for different material viscosity or processing temperature.
The piston rod of hydraulic cylinder is made the exsertile bar in two ends, and then the one end is as homogenising pin 4, and its other end stretches out outside the hydraulic cylinder and has scale, uses as the insertion depth visual inspection.
The also available screw thread of pin 4 is connected with piston rod in the hydraulic cylinder, when pin 4 wearing and tearing, can change pin 4 quickly, and expense is also less.
Claims (2)
1, the pin adjusting device of the pin type of screw arbor extruder of a kind of processing rubber, thermoplastic, have around material tube inner wall and approximately equidistantly distribute on the axial direction and also radially extend, point to the pin of a rotating screw rod longitudinal axis in extruder cylinder, inserting barrel place screw flight at pin is cut off, and adjusting device that is used to adjust the pin insertion depth, it is characterized in that, pin is made up of the piston rod of hydraulic cylinder, and hydraulic cylinder is fixed on the extruder cylinder.
2, according to the described pin adjusting device of claim 1, it is characterized in that, axially guide and be carved with mark by hydraulic cylinder facing to the other end of piston rod effect end.
