The specific embodiment
Describe specific embodiments of the present invention in detail below in conjunction with accompanying drawing.
Like Fig. 1, shown in Figure 2; Be used for the rotary shaft braking device of towel folder, comprise: be arranged on the left shell 21 and right shell body 22 of rotating shaft 1 both sides, the bottom of left shell 21 and right shell body 22 interconnects; Inside, upper end at left shell 21 and right shell body 22 is respectively arranged with cavity; In cavity, all be respectively arranged with brake block 3 and be arranged between rotating shaft 1 and the two-piston 4, be respectively arranged with installing hole 5 in the inside of two-piston 4 with piston 4, two brake blocks 3; In two installing holes 5, be respectively arranged with hold-down screw 6 and spring 7; One end of hold-down screw 6 is arranged in the installing hole 5, and the other end of hold-down screw 6 passes piston 4 and is connected with housing, on the hold-down screw 6 in the spring 7 sheathed installing holes 5; Be provided with compressed air inlet 8 in the bottom of right shell body 22; The air inlet pipe of the inside of compressed air inlet 8 through being arranged on right shell body 22 lower ends is connected with the air inlet 10 that is arranged on left shell 21 lower ends, and air inlet 10 cooperatively interacts with the left atmospheric pressure cavity 11 that is arranged on piston 4 bottoms and is connected, and compressed air inlet 8 cooperatively interacts with the right atmospheric pressure cavity 111 that is arranged on piston 4 bottoms and is connected.
As shown in Figure 2, in the housing in two hold-down screws, 6 outsides, be respectively arranged with Simmer ring 12, on piston 4, also be respectively arranged with piston packing 13 near atmospheric pressure cavity 11.
As shown in Figure 2; The bottom of left shell 21 and right shell body 22 is interconnective through upper spacer 141 and lower clapboard 142; Between upper spacer 141 and lower clapboard 142, be provided with connection chamber 15; Inner with being arranged on left shell 21 and the right shell body 22 lower ends respectively air inlet pipe 91 in the two ends of connection chamber 15 is connected with air inlet pipe 92, is respectively arranged with sealing ring 161 and sealing ring 162 in the outside of upper spacer 141 and lower clapboard 142.
