Description
Technical field
The present invention relates to carding machine, relate in particular to transmission device of cotton combing machine.
Background technology
The carding machine that generally uses has A186C at present, models such as A186D, its drive mechanism as shown in Figure 1, existing carding machine all comprises doffer 1, stripping roller 2, transfer roller 3, bottom roll 4, topping roll 5, lap roller 6, give cotton roller 7, cylinder 35, licker-in 39, doffer's motor 8, doffer's transmission mechanism, cylinder motor 31 and cylinder transmission mechanism, wherein the doffer 1, stripping roller 2, transfer roller 3, bottom roll 4, topping roll 5, lap roller 6, drive for cotton roller 7 by doffer's transmission mechanism by doffer's motor 8, the drive path of doffer's transmission mechanism is: doffer's motor 8 is by belt wheel 9, belt 11, drive 12, through gear train 14,15,16 drive doffer 1, stripping roller 2 rotates, again through gear 17,18,19,20,21,22,23 mobilization rollers 3, bottom roll 4, topping roll 5 rotates, by bevel gear 24,25,26,27 drive lap roller 6 rotates, at last by gear train 28,29,30 drive to cotton roller 7 rotations; Cylinder 35, licker-in 39 are then driven by the cylinder transmission mechanism by cylinder motor 31, and the drive path of cylinder transmission mechanism is: cylinder motor 31 drives cylinder 35, licker-in 39 rotations by belt wheel 32,34,36,38.
The motion of doffer's transmission mechanism and cylinder transmission mechanism requirement is in the carding machine: the cylinder transmission mechanism is running earlier, when its rotating speed reaches predetermined value, doffer's transmission mechanism just can turn round, for the ease of the sliver repiece, doffer's transmission mechanism is at the necessary low cruise of start of run, repiece finishes the back and requires evenly speed-raising, could guarantee the uniformity that the sliver bar is done like this.
In existing carding machine, for just guarantee doffer's motor 8 and after the cylinder transmission mechanism reaches desired speed, start that people are equipped with centrifugal switch 40 on licker-in 39, after licker-in 39 reaches desired speed, control doffer's motor 8 by centrifugal switch 40; In order to satisfy the fast requirement in slow earlier back of doffer's transmission mechanism, people select for use double-speed motor as doffer's motor 8, select low or first gear during startup earlier for use, select top gear again for use after repiece finishes; Doffer's transmission mechanism must possess the technological requirement of different rotating speeds when processing different cultivars in order to satisfy carding machine, people are designed to adjustable gear train with gear train 14,15,16, guarantee that doffer's transmission mechanism reaches corresponding process speed requirement, people just are furnished with the gear changing group of 18～34 teeth at random when carding machine dispatches from the factory, so that select for use during people's speed governing.
But still there is following deficiency in actual use in existing carding machine:
1. all there is the sudden change of speed in startup, speed in doffer's motor 8 when switching, though installed flywheel 10 additional on the output shaft of doffer's motor 8, rate conversion still can't realize continuously, transition reposefully, and this must influence the uniformity that the sliver bar is done; Because there is sudden change in speed, can bring bigger instant impact to carding machine, gear and other driving member damage or wearing and tearing easily.
2. during different cultivars, according to technological requirement, doffer's transmission mechanism needs different rotating speeds to carding machine in processing, and the collocation that this moment must change gear group 14,15,16 makes it to satisfy speed change request, its adjustment, use all cumbersome.
3. carding machine is in operation process, and motor is subjected to the influence of line voltage and load easily, and rotating speed of motor has fluctuation, thereby influences cotton bar evenness.
4. need to use 2 motors in complete machine, its power is respectively: doffer's motor 1.5kW/0.75kW; Cylinder motor 3.5kW, general power is 5kW, energy consumption is big.
Summary of the invention

The drive path of this transmission device of cotton combing machine is: cylinder motor 31 is by belt wheel group 32,34 drive cylinder 35 rotates, again by belt wheel group 36,38 drive licker-in 39 rotates, the drive 41 that is fixed on licker-in 39 lower ends drives the drive 425 on the power shaft 423 in the magnetic powder clutched speed regulator 42, again by the drive 12 in the drive 425 drive doffer transmission mechanisms that are installed on the output shaft, then by gear train 14,15,16 drive doffer 1, stripping roller 2 rotates, through gear 17,18,19,20,21,22,23 mobilization rollers 3, bottom roll 4, topping roll 5 rotates bevel gear 24,25,26,27 drive lap roller 6, gear train 28,29,30 drive to cotton roller 7 rotations.
Because doffer's transmission mechanism links to each other with the cylinder transmission mechanism by magnetic powder clutched speed regulator 42, motion to cylinder transmission mechanism and doffer's transmission mechanism during carding machine work requires all can record parameter is controlled magnetic powder cluth 421 by control device input current by tachogenerator 422, by the size of magnetic powder cluth 421 changes to output shaft rotary damping moment of torsion, guarantee the coordination of cylinder transmission mechanism and doffer's transmission mechanism, the chain of doffer's transmission mechanism and cylinder transmission mechanism can be realized by magnetic powder clutched speed regulator 42, the stepless time adjustment of doffer's transmission mechanism can be realized again.
The present invention has compared following advantage with the transmission device of existing carding machine:
1. doffer's transmission mechanism is all realized by magnetic powder clutched speed regulator 42 when switching in startup, speed, speed is excessively steady, does not have velocity jump, the worker's of both being convenient to weave spinning-in operation, can improve cotton bar evenness again, greatly improve the stability of carding machine operation.
2. when the processing different cultivars, adjust doffer's rotating speed and need only direct control set for adjusting, carry out the numeral setting by button and get final product, need not to carry out the replacing collocation of gear train, simple to operation.
3. doffer's transmission mechanism is regulated the electric current of controlling magnetic powder cluth by digital PID, can guarantee the velocity-stabilization of doffer's transmission mechanism.Control device adopts voltage compensation technology, overcomes the influence of voltage ripple of power network to doffer's transmission mechanism smoothness of operation;
4. the main power of complete machine is cylinder motor 3.5kW, has saved doffer's motor 1.5kW, and the power of magnetic powder cluth is 50W only, thereby energy-saving effect is remarkable.
