Description
Technical field
The utility model relates to printing Fabricating machinery, relates in particular to one rational in infrastructure, the constant tension formula dispensing shaft structure of safety and stability.
Background technology
Dispensing shaft tension control at present, is divided into:
A, electric machine control type: servomotor, alternating-current variable frequency motor torque pattern;
B, mechanical controllable type: magnetic brake, pneumatic brake;
C, electric machine control type: tension force control and the calculation of acceleration and deceleration tension force are easily controlled, if but startup-shutdown moment is too urgent too fast, motor reaction is not as good as having the moment jitter conditions of pulling material, unless adding the pneumatic floating bar of physical construction eliminates in storage rack mode, maybe the acceleration and deceleration smoothness that starts moment is slowed down, can slightly relieve jitter conditions, but still not good in time efficiency and characteristic, and long-term slowspeed machine easily damages, easily shake that Ultra-Low Speed torque is not enough;
D, mechanical controllable type: when shutdown, also lack self-sustaining power, therefore material is easily lax, Acceleration of starting moment can relax because of material itself, and has moment to be tightened to the situation of material, but ultra low speed operation can be stablized the splendid low-speed characteristic of not shaking.
Utility model content
The purpose of this utility model is, overcomes the above-mentioned defect of prior art, provides a kind of rational in infrastructure, the constant tension formula dispensing shaft structure of safety and stability.
For achieving the above object, the technical scheme that the utility model provides is as follows: a kind of constant tension formula dispensing shaft structure, comprise a body, on body, be disposed with from left to right dispensing shaft, collecting shaft, dispensing shaft is provided with the excessive gear of the first dispensing shaft, the excessive gear of the first dispensing shaft is engaged with the excessive gear of the second dispensing shaft, the excessive gear of the second dispensing shaft front is provided with magnetic-powder clutch, magnetic-powder clutch is provided with clutch input shaft and clutch output shaft, clutch input shaft is provided with Clutch input shaft belt pulley, clutch output shaft and the excessive gear of the second dispensing shaft are coaxially fixing, Clutch input shaft belt pulley below is provided with reverse motor output belt pulley, reverse motor output belt pulley is connected with reverse motor.
Between Clutch input shaft belt pulley and reverse motor output belt pulley, opposite force drive belt is set and realizes belt-driving.
Usefulness of the present utility model is: by the magnetic brake of dispensing shaft, change magnetic-powder clutch into, in the time that dispensing shaft shuts down or be about to stop, impose a low-speed reverse in magnetic-powder clutch input shaft side and rotate force source, can be about to stop the stable characteristic of moment utilization magnetic-powder clutch Ultra-Low Speed at dispensing shaft, allowing dispensing shaft stablize stops, rotate and still impose low-speed reverse after stopping, object is stablized and slight opposite force distance the normal maintenance of dispensing shaft, prevent that material is because stopping locating relaxation cases, when starting and departing from after ultra low speed operation, the reverse motor of magnetic-powder clutch input shaft shuts down, brake safely and embrace structure and do not rotate by the power-off of the rear side of motor own, rational in infrastructure, effectively control material strip tension force, keep constant tension, meet various processing procedure requirements, be widely used in printing, bag, papermaking, weaving, electric wire field.
Brief description of the drawings

Fig. 2 is the utility model constant tension formula dispensing shaft structure rear isometric view.
Detailed description of the invention
Be further described with regard to the technical solution of the utility model below in conjunction with accompanying drawing and preferred embodiment.
As Fig. 1, shown in Fig. 2, a kind of constant tension formula dispensing shaft structure described in the utility model, comprise a body 100, on body 100, be disposed with from left to right dispensing shaft 1, collecting shaft 2, dispensing shaft 1 is provided with the excessive gear 11 of the first dispensing shaft, the excessive gear 11 of the first dispensing shaft is engaged with the excessive gear 12 of the second dispensing shaft, the excessive gear of the second dispensing shaft 12 fronts are provided with magnetic-powder clutch 3, magnetic-powder clutch 3 is provided with clutch input shaft (accompanying drawing does not show) and clutch output shaft (accompanying drawing does not show), clutch input shaft is provided with Clutch input shaft belt pulley 4, the excessive gear 12 of clutch output shaft and the second dispensing shaft is coaxially fixing, Clutch input shaft belt pulley 4 belows are provided with reverse motor output belt pulley 5, between Clutch input shaft belt pulley 4 and reverse motor output belt pulley 5, opposite force drive belt 6 is set and realizes belt-driving, reverse motor output belt pulley 5 is connected with reverse motor 7.
Body 100 fronts are provided with some material strip driven shafts 8, on material strip driven shaft 8, material strip can be set.
Above, dispensing shaft 1 Ultra-Low Speed rotates or stops operating down, reverse motor 7 starts to rotate backward, through parts reverse motor output belt pulley 5, opposite force drive belt 6, Clutch input shaft belt pulley 4 is transferred to the input shaft side of magnetic-powder clutch 3, magnetic-powder clutch 3 is given the moment size of the output shaft side of its size of current capable of regulating magnetic-powder clutch 3 according to controller, again through the excessive gear 12 of the second dispensing shaft, the excessive gear 11 of the first dispensing shaft is transferred to dispensing shaft 1, reach us and want to realize high low-speed stable control moment, during with shutdown, keep the opposite force of dispensing shaft 1 apart from object.
Turn round above if dispensing shaft 1 transfers middling speed to, reverse motor 7 stops antiport, by the power-off brake self-holding circuit of itself, and then the input shaft of pinning magnetic-powder clutch 3, rotary principle is not identical with magnetic brake for it.
Above-described is only principle of the present utility model and preferred embodiment.It should be pointed out that to those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some modification and improvement, also should be considered as belonging to protection domain of the present utility model.
