Description
Technical field
The present invention relates to the monomer crosspointer plate main spindle box of a kind of main spindle box of needing machine, particularly a kind of high-speed needling machine.
Background technology
Needle-punched non-woven is the most general in the nonwoven material production technology, the most a kind of production method.Because characteristics such as needle fabric have that permeability is good, strainability and mechanical performance are good, be widely used in multiple industries such as making geotechnological material, filtering material, architectural waterproof material, automotive trim, synthetic leather base material, felt with and live and use non-woven fabric material.At present, the output of needle-punched non-woven accounts for 1/4th of whole nonwoven material total amount.And, needle-punched non-woven has that processing technology is simple, flow process is short, the equipment combination is flexible, the product type that adapts to is many, the utilization field is wide, equipment investment is few, plurality of advantages such as the construction period is short are so the acupuncture production method is still the present and the future's fast development, a kind of topmost nonwoven material production technology that does not wane of containing of a specified duration.
Needing machine belongs to no spinning equipment, is divided into pre-pricking machine and main-needling machine in the course of the work usually.The front of pre-pricking machine generally need dispose lapper, purpose be fiber is paved into certain thickness continuous netted, fiber web is sent it into the acupuncture zone of needing machine after holding through adding of feeding roller afterwards, after the uninterrupted high-frequency reciprocal puncture of pricker, the needle punched fabric of first one-step forming is pulled out outside the machine by a pair of outlet roller.In the production line of a needle fabric, all needing machines of pre-pricking machine back all are called main-needling machine, no matter dispose how many platforms, purpose is exactly that the eedle-punched non-wovens behind the thorn is in advance reinforced and had a shave, and produces the product that has certain intensity and can meet the need of market.
The page or leaf needing machine is born in Britain in last century, and along with the continuous application of new technology, new material, every technical performance of modern needing machine improves a lot in decades.But its basic principle all is identical, as shown in Figure 1, promptly drives the needle plate that pricker is housed by eccentric wheel connecting rod mechanism and moves up and down, and reaches thorn is implemented reinforcing at processed fiber web purpose.
Though the operation principle of needing machine is identical, the mechanism form of its main transmission is also inequality.Because specification requirement difference from low speed to high speed, the version of main transmission are also different.In the design of high-frequency needing machine at home, mainly contain two kinds of mechanism forms: the one, adopt main shaft box, promptly parts such as cam, connecting rod, slide block are included in the casing; The 2nd, no case gear rocker-type, promptly cam, connecting rod blow-by, slide block mechanism adopts pinion and-rack.Respectively there are advantage, parallel development in two kinds of mechanisms.The most main shafts that adopt of the needing machine of present domestic frequency on 1000r/min are box.
Since domestic first the high frequency needle punching machine of the eighties in last century is born, spindle box mechanism does not have much improvement, though acupuncture apparatus producer is numerous, the size of main spindle box inner body but substantially roughly the same, the original spindle box mechanism of homemade needing machine mainly contains three kinds of forms.Wherein, Fig. 2, single shaft one-board shown in Figure 3, Fig. 4, twin shaft double-plate shown in Figure 5; Another is the twin shaft one-board.
The equilibrium principle of the described former single shaft one-board main spindle box of Fig. 2, Fig. 3 is different from other mode, is a kind of of mechanism's symmetrical balance, and the inertia couple in its rotary course is not balanced.Its motion process: main shaft conjunction 10 drives four former connecting rods 9, and these four former connecting rods 9 drive the weight that is equivalent to two balance weights 13 and move up and down, the frictional force of the puncture force of pricker and former fairlead 14 is all quite big, so this main spindle box is not suitable for bearing the acupuncture state of more high capacity.Fig. 4 and Fig. 5 are the schematic diagrames of former twin shaft double-plate main spindle box, and the balance mode of this main spindle box also is a kind of of mechanism's balanced configuration, but it balances its own inertial couple and most of inertia force.Unreasonable structure of not enough, the casing 20 of carrying or the like when but its bulky, former connecting rod 9 and former link pin 12 are used for more speed, these have hindered the application extension of this former main spindle box.And owing to be subjected to the restriction of the distance of original main spindle box appearance and size and two push rods 17, design of Main Drive can only adopt sectional type to divide, and the space that does not almost reduce cost also is its reason that can not continue to develop.
More than three kinds of spindle box mechanisms, because the distance between two push rods of their fixing same needle plate beams is 600mm, so the design needle plate length the time all about 1200mm, so the main transmission of the box needing machine of main shaft and needle plate have partly formed the design of sectional type.The subject matter that original main spindle box exists have following some: 1) the main spindle box volume is excessive, and processing, transportation, assembling etc. are all inconvenient; 2) fixed range between two push rods cannot reduce the quantity of push rod, is subjected to the restriction of main spindle box appearance and size equally, and the quantity of main spindle box also can't reduce, and this causes the cost of needing machine to reduce; 3) part that participation is rotated in the main spindle box is too much, has increased the temperature of lubricating oil, is unfavorable for the sealing of lubricating oil; 4) there is irrational place in the original structure of main shaft casing, is unfavorable for the cooling of lubricating oil; 5) there is the slight error of secondary operations in the split type combination of main shaft and cam; 6) on average to get off be 1 to the bearing fulcrum of support link, stressed uneven relatively.
