Abstract
The utility model discloses an auxiliary braking device for passive unreeling. An unreeling shaft (3) is arranged on a rack through a base seat (1), a belt pulley (2) is arranged on the unreeling shaft (3), a belt upright tube (4) and a linkage central shaft (8) are arranged on a baseboard (7), a belt (5) is wound on the belt pulley (2) and the belt upright tube (4), a limit plate (10) is arranged on the linkage central shaft (8), a tension spring upright tube (9) is arranged on the limit plate (10), one end of a tension spring (6) is connected with the belt upright tube (4), the other end of the tension (6) is connected with the tension spring upright tube (9), a linkage oscillating bar (12) is arranged on the tail end of the linkage central shaft (8), a linkage shaft (15) is arranged on the linkage oscillating bar (12), and a linkage rolling shaft outer sleeve is arranged on the linkage shaft (15). The auxiliary braking device for the passive unreeling reduces an inertial motion of the unreeling through the friction resistance between the belt pulley and the belt, and due to the fact that the friction is automatically adjusted through the tension spring, not only can the replacing of a material roll not be impacted, but also the smooth and reliable conveying process of the material roll can be guaranteed.
Description
Technical field
The utility model relates to the unwinding device of disposable sanitary articles industry production line, is specifically related to the passive auxiliary brake that unreels.
Background technology
In the disposable sanitary articles industry, production all is to be supported on the equipment rack with unreeling shaft with material, generally unreel dual mode: need to adopt with the material of pipeline synchronization interlock power wheel control to unreel, auxiliary material adopt passive unreeling, because the restriction of the device space is in order to save cost on the other hand on the one hand.And along with the widespread use of modernization science and technology on equipment, the running velocity of equipment is more and more faster, for satisfying production efficiency, material webs also is increasing also heavier, and adopt the passive material webs that unreels, inertia in rotation transmits is also increasing, in conveyor line production on the impact of product design also embody more obvious, have influence on the stability of product, adopt the inertia effects of the diameter reduce material webs in unreeling with minimizing for this reason, and the diameter that reduces material webs can cause the frequent material webs, has a strong impact on the production efficiency of equipment, has brought manpower, the waste of material resources and economic loss.
Summary of the invention
The purpose of this utility model is: in the situation that do not change the Whole Equipment design, for passive unreeling shaft provides a kind of complementary braking control device that unreels when material transmits, reduce material webs and unreel inertia motion in the process in production, elimination improves production efficiency and the product quality of equipment to the impact of product quality.
Technical solution of the present utility model is: this auxiliary brake comprises belt pulley, the belt vertical rod, belt, extension spring, base plate, the interlock center shaft, the extension spring vertical rod, positioning plate, limit shaft, the interlock fork, bearing, interlock roller bearing overcoat and universal driving shaft, unreeling shaft through floor installation on frame, belt pulley is installed on the unreeling shaft, mounting base on the frame, the vertical rod of parallel installation belt and interlock center shaft on the base plate, belt is wrapped in belt pulley and the belt vertical rod, mounting limit plate on the interlock center shaft, extension spring vertical rod and limit shaft are installed on the positioning plate, one end of extension spring connects the belt vertical rod, the other end of extension spring connects the extension spring vertical rod, interlock center the tip of the axis is installed the interlock fork, through support arm universal driving shaft is installed on the interlock fork, universal driving shaft is installed interlock roller bearing overcoat through bearing.
In the real work, when material webs when maximum is the heaviest, the inertia that transmits operation is also larger, the first transaction of a day's business distance of interlock fork is also larger, the pulling force of at this moment extension spring also is maximum, the friction force between belt and the belt pulley is also larger; And along with constantly the dwindling of material webs, the retraction of extension spring guarantees that it is the coordinated operation state that universal driving shaft and material webs transmit always, and the pulling force of while extension spring also is more and more less, does not affect the operation of unreeling shaft.
The utility model is simple in structure, and is with low cost, open installation and operation, adopt the friction drag between belt pulley and the belt to reduce the unreeling shaft inertia motion, by extension spring regulating friction force voluntarily, neither affect the replacing of material webs, guarantee again smooth-going reliable at transport process of material webs.
Description of drawings

Fig. 2 is that the utility model is installed and used figure in equipment.
Among the figure: 1 base, 2 belt pulleys, 3 unreeling shafts, 4 belt vertical rods, 5 belts, 6 extension springs, 7 base plates, 8 interlock center shafts, 9 extension spring vertical rods, 10 positioning plates, 11 limit shafts, 12 interlock forks, 13 bearings, 14 interlock roller bearing overcoats, 15 universal driving shafts, 16 material webs.
The specific embodiment
As shown in Figure 1, this auxiliary brake comprises belt pulley 2, belt vertical rod 4, belt 5, extension spring 6, base plate 7, interlock center shaft 8, extension spring vertical rod 9, positioning plate 10, limit shaft 11, interlock fork 12, bearing 13, interlock roller bearing overcoat 14 and universal driving shaft 15, unreeling shaft 3 is installed on the frame through base 1, belt pulley 2 is installed on the unreeling shaft 3, mounting base 7 on the frame, parallel installation belt vertical rod 4 and interlock center shaft 8 on the base plate 7, belt 5 is wrapped in belt pulley 2 and the belt vertical rod 4, mounting limit plate 10 on interlock center shaft 8, extension spring vertical rod 9 and limit shaft 11 are installed on the positioning plate 10, one end of extension spring 6 connects belt vertical rod 4, the other end of extension spring 6 connects extension spring vertical rod 9, the end of interlock center shaft 8 is installed interlock fork 12, through support arm universal driving shaft 15 is installed on the interlock fork 12, universal driving shaft 15 is installed interlock roller bearing overcoat 14 through bearing 13.
As shown in Figure 2, in the real work, when material webs 16 maximum, the first transaction of a day's business distance of interlock fork 12 is also larger, the pulling force of at this moment extension spring 6 also is maximum, and the friction force between belt 5 and the belt pulley 2 is also larger, and the transmission inertia effects of material webs 16 has been played good control action; And along with constantly the dwindling of material webs 16, extension spring 6 is also in continuous shortening, and pulling force also is more and more less, and the friction force between belt 5 and the belt pulley 2 is also diminishing, and does not affect the operation of unreeling shaft 3.
