A kind of automatic filter element cutter
Technical field
The present invention relates to filter element and produce apparatus field, particularly relate to a kind of automatic filter element cutter.
Background technology
Filter element is that polymer (PP polypropylene) is extruded by spinneret orifice under melt-blown state, through high velocity, hot air effect, make superfine fibre the poroid water purification filter consumptive material produced by receiving the non-uniform velocity transmission of axle, now with promoting the use of of domestic various purifiers, the consumption of filter element is also skyrocketed through.
According to usual customer demand, the outer surface requirement of filter element is smooth and external diameter size requirements is in the range of standard of tolerance, and two sections require smooth, smooth.The positive and negative 1mm of length requirement.
In order to meet the demand of client, more domestic companies are by using the constant velocity rotation receiving axle and reciprocating motion to control filter element external diameter size, but this method has many point defects.
1. need many when receiving axle and change, a large amount of waste material can be produced.
2. the reception axle changed needs manually filter element taken off and manually cut.
3., because reciprocating limitation can cause two filter element to be scrapped, yield rate only has about percent 70.
Along with the development variable speed transmission of technology has been applied on melt-blowing equipment so that the yield rate of filter element is greatly improved.But automated production cannot be realized.
In order to realize cutting the Korea S of automatization of filter element and Taiwan Deng Duojia Automation Co., Ltd is all researched and developed, use motor and screw rod to combine implementation withdrawing and feed thus cut filter element, so can produce some not enough percent defective higher.
1. one driven by motor screw rod transverse movement another driven by motor blade circumgyration incision filter element simultaneously during cutting, rapid return cannot can stay otch, filter element section not to reach requirement at filter element section when withdrawing because screw rod limits.
2. because installing two bigger difficulties of sliding of motor slide rails pressurized, and it is unstable to swing bigger support.Easily cause damage maintenance frequency more.
3. filter element Cutting Length is shorter, and longer filter element also needs manually to cut.
The most automatically constantly attempt and innovation on the basis of cutting, utilize the adjustability of pneumatic element to overcome feed slow and withdrawing this difficult problem fast, make the filter element both ends of the surface cut out smooth, smooth, meet the requirement of client.

Detailed description of the invention:
Below in conjunction with the accompanying drawings, by embodiment, the present invention is described in further detail:
A kind of automatic filter element cutter, including base 16, slide rail 4: base 16 upper end is provided with a pair slide rail 4, slide rail 4 front end is slidably fitted with fore-stock 3, fore-stock 3 side is installed with cutting knife cylinder 7, the piston end of cutting knife cylinder 7 connects extension bar 17, extension bar 17 front end is provided with cutter head 9, and cutting knife cylinder 7 side is provided with cutting knife cylinder electromagnetic transducer 8, is provided with the electromagnetism ring coordinated with cutting knife cylinder electromagnetic transducer 8 in cutting knife cylinder 7;Fore-stock 3 upper end is provided with front receiving slit and fixes runner 18, and front receiving slit is installed with fore bearing 25 in fixing runner;Slide rail 4 rear end is slidably fitted with after-poppet 19, after-poppet 19 upper end is provided with rear receiving slit and fixes runner 13, rear receiving slit is installed with rear bearing 14 in fixing runner 13, filter element receiving slit 1 is fixed runner through forward and backward receiving slit and can rotate in forward and backward receiving slit fixes runner, runner 2 is installed in filter element receiving slit 1, base 16 rear end is provided above rotary cylinder 12, and rotary cylinder 12 is connected to filter element receiving slit 1 end and drives filter element receiving slit 1 to rotate;There is in the middle part of base 16 fixed plate 20, fixed plate 20 side is provided with stroke cylinder 10, stroke cylinder 10 side is provided with stroke cylinder electromagnetic transducer 11, the electromagnetism ring coordinated with stroke cylinder electromagnetic transducer 11 is installed in stroke cylinder 10, base 16 rear end is fixed with the connecting rod 15 stretched out, after-poppet 19 front end is installed with top board 21, through hole is had on top board 21, top board 21 is sleeved on connecting rod 15 and connecting rod 15 is through through hole, spring 22 it is set with on connecting rod 15, spring 22 leans top board 21 from behind, the piston end of stroke cylinder 10 is from above leaning top board 21;Also having extension bar 23 in the middle part of base 16, extension bar 23 front end is provided with photoswitch 6, and after-poppet 19 side is installed with thin bar 24, and thin bar 24 front end has photoswitch baffle plate 5, can shelter from photoswitch 6 when photoswitch baffle plate 5 moves.Photoswitch 6 is connected by electrical wiring to PLC and controls device, PLC controls device and is connected respectively to cutting knife cylinder solenoid valve, stroke cylinder electromagnetic valve and rotary cylinder electromagnetic valve, cutting knife cylinder solenoid valve is connected to cutting knife cylinder, stroke cylinder electromagnetic valve is connected to stroke cylinder, and rotary cylinder electromagnetic valve is connected to rotary cylinder.PLC controls device and is also associated with alarm device.
The specific works principle of the present invention is:
1. filter element is output by receiving the variable speed transmission on axle, elongation.Through elongation after a while, filter element enters into 1(filter element dump tank).
2. filter element continues to extend forward arrival 2 in dump tank, and (runner-can be with filter element synchronous rotary core) be controlled in the margin of tolerance of requirement at the counteracting force lower filter of spring.
3. the effect lower filter at reception axle extends the most forward and will drive 3(support) at 4(slide rail) upper mobile until 5(photoswitch baffle plate) shelter from 6(photoswitch) produce signal source.
4. signal is sent to PLC(programmable controller by electric wire), PLC controls electromagnetic valve, electromagnetic valve by control input and output gas make 7(cut cylinder) elongation thus drive 9(blade holder) move downward cutting filter element.
5. could work when the 7 electromagnetism rings being elongated to be furnished with in 8(electromagnetic transducer-cylinder installation simultaneously) position time stop, simultaneously produce signal be sent to PLC, PLC by control electromagnetic valve make cutter lift.(time of cutting controls by controlling the height of 8 and the size of air inlet.)
5. simultaneously PLC performs next program, controls 10(stroke cylinder by controlling electromagnetic valve) elongation, (if not travelling forward a segment distance, constantly the filter element of elongation can withstand the filter element cut down thus cannot drop to drive 3 again to travel forward.)
6. could work when the 9 electromagnetism rings being elongated to be furnished with in 11(electromagnetic transducer-cylinder installation simultaneously) position time stop, produce signal simultaneously and be sent to PLC, PLC controls 12(rotary cylinder by controlling electromagnetic valve) rotarily drive 13(dump tank and fix that runner-runner is mounted on bearings can be rotated under the effect of 13) and 1 rotation, filter element drops in the placing box of indication.
7.PLC can control the time of upset, and after the time, PLC controls 12 and 9 resets by electromagnetic valve.(in this work time, photoswitch is blocked by 5 all the time, and after resetting when 12 and 9, photoswitch is no longer blocked, and as being also blocked, the incomplete alarm that resets can sound.) a now job time completes, and then waits next one work time.
Above-described embodiment is only the preferably embodiment of the present invention, and in addition, the present invention can also have other implementations.It should be noted that on the premise of without departing from present inventive concept, any conspicuously improved and modification all should fall under the scope of the present invention.
