Abstract
The utility model discloses a pneumatic braking device for passive unreeling. A base seat (1), a baseboard (4) and an air cylinder mounting seat (8) are arranged on a rack, a unreeling shaft (2) is arranged on the base seat (1), a linkage central shaft (5) is arranged on the baseboard (4), an air cylinder (7) is arranged on the air cylinder mounting seat (8), a limit plate (6) is arranged on the linkage central shaft (5), a limit shaft (9) is arranged on the limit plate (6), a linkage oscillating bar (10) is arranged on the tail end of the linkage central shaft (5), the air cylinder rod of the air cylinder (7) is connected with the linkage oscillating bar (10), a linkage shaft (13) is arranged on the linkage oscillating bar (10) through a support arm, and a linkage rolling shaft outer sleeve (12) is arranged on the linkage shaft (13) through a bearing (11). The pneumatic braking device for the passive unreeling is wide in generality, and due to the fact that a pneumatic structure device is convenient to operate and maintain, the pneumatic braking device for passive unreeling can be put into use once invested.
Description
Technical field
The utility model relates to the unwinding device of disposable sanitary articles industry production line, is specifically related to the passive pneumatically operated brake that unreels.
Background technology
In the disposable sanitary articles industry, producing material is supported on the equipment rack with unreeling shaft, 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.In order to guarantee the stability of product, adopt to reduce the material webs diameter and reduce inertia effects in unreeling, and the frequent material webs can have a strong impact on production efficiency of equipment, has brought waste and the economic loss of human and material resources.
Summary of the invention
The purpose of this utility model is: in the situation that does not change the equipment overall structure design, for transmitting, passive unreeling shaft material provides a kind of complementary braking control device, reduce the inertia motion of material webs in production unreels, 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 pneumatically operated brake comprises base plate 4, interlock center shaft 5, positioning plate 6, cylinder 7, cylinder mount pad 8, limit shaft 9, interlock fork 10, bearing 11, interlock roller bearing overcoat 12 and universal driving shaft 13, mounting seat 1 on frame, base plate 4 and cylinder mount pad 8, unreeling shaft 2 is installed on the base 1, interlock center shaft 5 is installed on the base plate 4, cylinder 7 is installed on the cylinder mount pad 8, mounting limit plate 6 on the interlock center shaft 5, mounting limit axle 9 on the positioning plate 6, the end of interlock center shaft 5 is installed interlock fork 10, the cylinder rod of cylinder 7 connects interlock fork 10, through support arm universal driving shaft 13 is installed on the interlock fork 10, through bearing 11 interlock roller bearing overcoat 12 is installed on the universal driving shaft 13.
In the real work, pressure regulating valve cuts out, cylinder is regained, and the first transaction of a day's business of interlock fork is apart from maximum; When material webs transmits operation, open pressure regulating valve and adjust to convenient pressure, interlock roller bearing overcoat is pressed on the material webs, and the transmission inertia effects of material webs has been played good control action; And along with constantly the dwindling of material webs, cylinder also is in continuous lifting, promotes universal driving shaft and keeps coordinated operation with the material webs transmission always.
The utlity model has following advantage: 1, adopt cylinder automatically to regulate, rely on the interlock fork to control the inertia motion that the friction drag that links between roller bearing overcoat and the material webs reduces unreeling shaft; 2, for the fork that prevents from linking moves at last, the roller bearing overcoat that causes linking causes collision to unreeling shaft, and mounting limit plate and limit shaft are protected on the interlock fork; 3, this passive pneumatically operated brake that unreels adopts open installation and operation, when guaranteeing the smooth-going transmission of material webs, does not affect again being convenient for changing of material webs.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 of the present utility modelly installs and uses figure in equipment.
Among the figure: 1 base, 2 unreeling shafts, 3 material webs, 4 base plates, 5 interlock center shafts, 6 positioning plates, 7 cylinders, 8 cylinder mount pads, 9 limit shafts, 10 interlock forks, 11 bearings, 12 interlock roller bearing overcoats, 13 universal driving shafts.
The specific embodiment
As shown in Figure 1, this pneumatically operated brake comprises base plate 4, interlock center shaft 5, positioning plate 6, cylinder 7, cylinder mount pad 8, limit shaft 9, interlock fork 10, bearing 11, interlock roller bearing overcoat 12 and universal driving shaft 13, mounting seat 1 on frame, base plate 4 and cylinder mount pad 8, unreeling shaft 2 is installed on the base 1, interlock center shaft 5 is installed on the base plate 4, cylinder 7 is installed on the cylinder mount pad 8, mounting limit plate 6 on the interlock center shaft 5, mounting limit axle 9 on the positioning plate 6, the end of interlock center shaft 5 is installed interlock fork 10, the cylinder rod of cylinder 7 connects interlock fork 10, through support arm universal driving shaft 13 is installed on the interlock fork 10, through bearing 11 interlock roller bearing overcoat 12 is installed on the universal driving shaft 13.
As shown in Figure 2, in the real work, pressure regulating valve cuts out, cylinder 7 is regained, and the first transaction of a day's business of interlock fork 10 is apart from maximum; When material webs 3 transmits operation, open pressure regulating valve and adjust to convenient pressure, interlock roller bearing overcoat 12 is pressed on the material webs 3, and the transmission inertia effects of material webs has been played good control action; And along with constantly the dwindling of material webs 3, cylinder 7 also is in continuous lifting, promotes universal driving shaft 13 and transmits with material webs 3 and keep coordinated operation always.
