Description

High-speed filament winder for lamp

Lamp is a kind of infrastructure device of electric light source manufacturing with the high speed spiral filament forming machine, but its both slubbing silk of the many coiled filaments of coiling, also can be around single coil filament.

Spiral filament forming machine is exactly a machine of making coiled filament, and its course of work is by certain TPC value (number of turns of centimetre filament) requirement, around to the core silk tungsten filament.Traditional type high speed spiral filament forming machine is guide wheel or the guide rod that adopts high speed rotating, the tungsten filament on the tungsten filament dish is pulled out and the core silk that advances around average rate on.During this spiral filament forming machine wrapping wire, the tungsten filament discontinuity can only reach 3～5,000 rev/mins around speed.Improve again around speed and will add the coiling performance that electric current improves tungsten filament to tungsten filament.This technology trouble, and around speed also difficulty can reach 1.1 ten thousand rev/mins.The centrifugal wrapping wire method that grows up at present on the whole section tungsten filament that wrapping wire power is acted on equably throw out, has reduced tungsten filament wrapping wire performance demands, reaches 30,000 rev/mins around speed, also need not to add electric current.The spiral filament forming machine of corresponding centrifugal wrapping wire method is to adopt the logical threephase asynchronous machine of a Daepori, is coupled at a high speed around head and low speed core silk wire-moving system each several part by lifting two sleeve gears and belt.This wrapping wire mechanism is around different pitch or every centimetre of number of turns of different TPC() filament the time, need to change the pitch wheel of different-diameter D.TPC=(C)/(D), C are the machine constants.A kind of TPC of every like this change will do special-purpose pitch wheel, bothers, difficult energy flexible design filament.And this spiral filament forming machine is raised to 30000 rev/mins to common electric machine for about 3000 rev/mins, wherein has the material performance requirement height, problem such as the precision gear difficulty of processing is big.

The purpose of this utility model then is the problem at above-mentioned existence, and it is main around axle to provide a kind of direct employing high-speed electric expreess locomotive to drive, and by stepping motor or driven by servomotor core silk wire part, and changes the lamp high speed spiral filament forming machine that TPC can take turns with general pitch.

The utility model solution:

A kind of lamp high speed spiral filament forming machine, it partly is made up of feeding head part, the wire of core silk, it is characterized in that:

Main in a, the feeding head part master has logical arbor hole on axle on the rotor of axle design at high-speed electric expreess locomotive, and logical arbor hole front end is a taper hole, and payout eye is installed on the taper hole;

B, core silk wire part: the axle of stepping motor or servomotor is connected with the prime of deceleration gear, and the axle of tension adjustment wheel, pitch wheel, receipts silk dish is connected with the back level of deceleration gear, and little drum is pressed on pitch to filament by strap lug and takes turns.

Advantage of the present utility model:

The utility model has not only overcome the material performance requirement height of 30,000 rev/mins of raising speed gears, a series of problems that high speed and precision Gear Processing difficulty is big, and TPC is adjusted in the cooperation of two or three general pitch wheels down, key in program control word and can realize that TPC regulates continuously, need not a kind of TPC of every change and all will change the pitch wheel.Greatly facilitate filament design and test like this, in order to design with produce best filament, thereby promote the quality of electric light source products.

Fig. 1 is the utility model structural representation.

Fig. 2 is the rotor cutaway view of the utility model band master around axle construction.

Below in conjunction with accompanying drawing the utility model is further described:

Structure shown in Figure 1 can be divided into two parts: the cutaway view of the centrifugal feeding head of first's (sequence number 4～12,15) expression; All the other are second portion, the Motion Transmission sketch of expression core silk wire part.The filament-feeding tray 1 of magnetically damped, magnetic tension adjustment wheel 2 is positioned at the support left surface with guide wheel 3; Magnetic constant force square is received silk dish 14, and permanent linear speed pitch wheel 13 is positioned at the support right flank with guide wheel 17.The structural principle of tension adjustment wheel 2 is that the coaxial annular soft iron that the annular magnetic steel of rotation servo-actuated with certain attraction band changes.Regulate magnet steel and soft iron spacing, i.e. adjustable tension.Filament-feeding tray 1, receipts silk dish 14 structural principles and tension adjustment wheel 2 are roughly the same.

Master of the present utility model is on the rotor 5 of axle 6 designs at high-speed electric expreess locomotive 4, and main having on axle 6 led to arbor hole 12, in order to pass the core silk.Logical arbor hole 12 front ends are taper hole, and payout eye 11 is installed on the taper hole, and the preceding shaft extension of rotor 5 long thick (long 45～50mm, φ 14) is so that by dress wire wrapping disk 9 and fastener 15 thereof.Lead around axle 6, lead to the concentricity of arbor hole 12 and payout eye 11 less than 0.005mm.Correspondingly during high-speed electric expreess locomotive loading work, mainly also all requiring less than 0.005mm around axle 6 circular runouts and axial motion.Before wrapping wire work, earlier tungsten filament dish 9 is enclosed within main also fixing on axle 6 with fastener 15, the core silk is drawn from filament-feeding tray 1, through tension adjustment wheel 2 and guide wheel 3, pass mainly behind axle 6, logical arbor hole 12, payout eye 11 and seal wire ring 10, deliver to through guide wheel 17, pitch wheel 13 and to receive silk dish 14 and clamp and prepare to receive silk.Core silk wire part behind deceleration gear 18 reductions of speed at different levels, drives tension adjustment wheel 2 by stepping motor (or servomotor) 16, receives silk dish 14 and pitch wheel 13.Pitch wheel 13 is made speed stabilizing by the microcomputer instruction and is rotated, and its additional on every side three side drums wheel 19 and strap lug 20, the slubbing coiled filament that winds before payout eye 11 tightly is attached on 13 on the pitch wheel, skid preventing, try to achieve the uniformity of wire, that is improve every centimetre of number of turns of filament TPC() stability.On the other hand seal wire ring 10 is drawn and passed to the tungsten filament head in the tungsten filament dish 9.After above-mentioned preparation is finished, start the machine, microcomputer starts stepping motor (or servomotor) 16 and monitoring earlier, then starts high-speed electric expreess locomotive 4 and monitoring, stepping motor 16 drives core silk wire partially stabilized ground wire, and high-speed electric expreess locomotive 4 makes the master reach about 30,000 rev/mins high speed around axle 6.Tungsten filament dish 9 is also done to rotate with speed, and tungsten filament dish 9 is thrown on the wall of bobbins 7 to one section tungsten filament 8 between the seal wire ring 10, the centrifugal force of this section tungsten filament tungsten filament self tightly on the core silk of payout eye 11 fronts.Because two motors all operation in system controlled by computer, main rotating speed around axle 6 is stable, and the core silk also is that average rate is advanced.Therefore the pitch (being TPC) of the slubbing coiled filament that lays out is uniform.
