Abstract
The utility model relates to a dynamic balance device of a needle machine, which comprises two dynamic balance wheels symmetrically installed on two spindles of the needle machine. The dynamic balance device of the needle machine is characterized in that the dynamic balance wheels comprise wheel bodies and counter weight blocks. Grooves capable of containing the counter weight blocks are arranged on the wheel bodies, and the counter weight blocks are installed in the grooves. By setting the dynamic balance wheels into a split structure, a user can replace the counter weight blocks according to on-site adjustment effect without replacing the whole dynamic balance wheels, thereby enabling the correction and adjustment of dynamic balance to be convenient and quick, being capable of achieving good balance effect and enabling the needle machine to be stable and low in noise during work. Further more, the counter weight blocks are formed by a plurality of counter weight slices, thereby being more convenient and more precise to adjust.
Description
Technical field
The one-tenth that the utility model relates to a kind of nonwovens produces equipment, relates in particular to a kind of dynamic poise device of needing machine.
Background technique
In present needing machine; The moving fortune of control pricker generally is to adopt two motors to drive two main shafts respectively through belt pulley to rotate in the opposite direction; Drive wobbler action through main shaft again; Drive the needle beam connecting rod by eccentric wheel at last, needle beam connecting rod band push rod and is done moving of above-below direction along guide pin bushing.When tease needle machine is worked, its punch frequency reach 1500 times/more than the Min, and add needle beam, plant the deadweight of needle plate, so eccentric wheel in the running main shaft can produce powerful inertial force, thereby make needing machine produce violent vibration and noise.
Needing machine can produce violent vibration and rock when work, with quality that has a strong impact on product and output, even also can produce resonance and cause great potential safety hazard with factory, miscellaneous equipment.
For addressing the above problem; Normally on two main shafts, install two dynamic balancing wheels are set; The eccentric direction of two dynamic balancing wheels is opposite with two eccentric eccentric directions; Two dynamic balancing wheels balance the inertial force of main shaft, thereby make machine be able to take into account at fabric width, pin frequency, stationarity, noise etc., and many new problems that technical order and testing and measuring technology occur have also obtained solution.
Yet the present dynamic balancing wheel that adopts all adopts global design basically, is difficult to adjustment after the installation, if counterbalance effect is not good, need change the dynamic balancing wheel, is difficult to the counterbalance effect that reaches best.
Summary of the invention
The technical problem that the utility model will solve provides a kind of dynamic poise device of needing machine, and the dynamic poise device of this needing machine is simple in structure, and is easy to adjust, can reach preferable counterbalance effect, steady when making needing machine work, low noise.The technological scheme that adopts is following:
A kind of dynamic poise device of needing machine comprises two dynamic balancing wheels, and two dynamic balancing wheel symmetries are installed on two main shafts of needing machine, it is characterized in that: said dynamic balancing wheel comprises wheel body and balancing weight; Wheel body is provided with the groove that can hold balancing weight; Balancing weight is installed in the groove.
Dynamic balancing is taken turns and is set to the branch body structure, according to the field adjustable effect, changes balancing weight, need not to change whole dynamic balancing wheel, makes dynamically balanced correction, easy to adjust quick can reach preferable counterbalance effect, steady when making needing machine work, low noise.
Preferred version as the utility model is characterized in that: also comprise screw rod and nut; Said groove is provided with first through hole, and the relevant position of said balancing weight is provided with second through hole; Balancing weight is installed on the groove of wheel body through screw rod, nut, first through hole and second through hole.Through screw rod and the such demountable structure of nut, balancing weight is installed on the wheel body replacing of more convenient balancing weight.
As the further preferred version of the utility model, it is characterized in that: said balancing weight comprises at least two counterweight thin slices, and the relevant position of counterweight thin slice is provided with second through hole.Balancing weight is set to constitute by a plurality of counterweight thin slices are superimposed, when debugging at the scene, increases the quantity of counterweight thin slice gradually; Make the weight of balancing weight increase gradually; Need not to change balancing weight and just reach conveniently and regulate, proofread and correct dynamically balanced purpose, convenient, dynamically balanced adjusting is more accurate.
As the utility model preferred version further, it is characterized in that: the orthographic projection of said groove on wheel body is fan-shaped, and the shape and the groove of said balancing weight are complementary.The groove and the balancing weight that are provided with like this more meet the appearance requirement that dynamic balancing is taken turns, and make integral body more neat, attractive in appearance, more help dynamically balanced adjusting.
The dynamic poise device of the needing machine of the utility model; Be set to the branch body structure through the dynamic balancing wheel,, change balancing weight according to the field adjustable effect; Need not to change whole dynamic balancing wheel; Make and dynamically balanced correction, easy to adjust quick can reach preferable counterbalance effect, steady when making needing machine work, low noise.Further balancing weight is made as by a plurality of counterweight thin slices and constitutes, more convenient adjusting is regulated more accurate.

Embodiment
Do further explanation below in conjunction with the preferred implementation of accompanying drawing and the utility model.
As depicted in figs. 1 and 2, the dynamic poise device of this needing machine comprises two dynamic balancing wheels 1, draws together screw rod 2 and nut 3; Two dynamic balancing are taken turns 1 symmetry and are installed on two main shafts 4 of needing machine; Dynamic balancing wheel 1 comprises wheel body 11 and balancing weight 12; Wheel body 11 is provided with the groove 13 that can hold balancing weight 12, and the orthographic projection of groove 13 on wheel body 11 is fan-shaped, and the shape of balancing weight 12 and groove 13 are complementary; Groove 13 is provided with first through hole 14, and the relevant position of balancing weight 12 is provided with second through hole 15; Balancing weight 12 is installed on the groove 13 of wheel body 11 through screw rod 2, nut 3, first through hole 14 and second through hole 15.As shown in Figure 2, balancing weight 12 comprises at least two counterweight thin slices 121, and the relevant position of counterweight thin slice 121 is provided with second through hole 14.
Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, dynamic balancing wheel 1 is installed on the main shaft 4 of needing machine, and makes that the eccentric direction of eccentric direction and eccentric wheel 5 of dynamic balancing wheel 1 is opposite.During needing machine work; Two eccentric wheels 5 high-speed rotation in the opposite direction under the drive of two main shafts 4; Drive push rods high-speed motion about in the of 7 through connecting rod 6; Make main shaft 4 produce bigger inertial force, dynamic balancing wheel 1 makes needing machine stable working, low noise at the inertial force that then balances main shaft 4.And in when debugging, take turns 1 equilibrant when not enough when dynamic balancing is horizontal, unclamp nut 3, add counterweight thin slice 121, again locking nut 3 just can, debug convenient and swiftly, adjusting is accurate.
