Problems solved by technology
[0003] In the traditional lever-type pneumatic cradle of the drafting and pressurizing device, the cradle is fixed by the upper and lower clamps. Adjust the two connecting screws of the upper and lower clamps to change the rotation of the upper and lower clamps to achieve pressure adjustment. The pressure transmission crank mechanism only The pressure is simply transmitted, and the pressure cannot be adjusted. The fixing and pressure adjustment of the cradle are on the same mechanism, which is time-consuming and laborious. Large, the pressure cannot be kept stable for a long time, the range of adjustable pressure is also small, the difference between spinning spindles is large, the operation is difficult, the labor intensity is high, the work efficiency is low, and the spinning quality is not high

Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0020] Such as figure 1 A pneumatic cradle is shown, including a cradle positioning and locking mechanism and a screw stepless pressure adjustment mechanism. The cradle fixing and locking and pressure adjustment are designed separately and independently without interfering with each other. The positioning and locking mechanism of the cradle includes the support upper card 4, the support and fastening lower card 5, the hexagonal support tube 10, the fixed square nut 71 and the fastening screw 72; the spiral stepless pressure adjustment mechanism includes the pressure transmission crank 3 and the adjustment screw rod 8 , locking screw 9 and air bag 12, a pressure pin sleeve 11 is provided at the fulcrum of contact with pressure transmission crank 3, and pressure regulation is realized by changing the height of pressure transmission crank 3 conta...

The invention discloses a pneumatic cradle which comprises a cradle positioning, fixing and locking mechanism and a helical stepless pressure regulating mechanism, wherein the cradle positioning, fixing and locking mechanism consists of a supporting upper clamp, a supporting fastening lower clamp, a hexagonal supporting tube, a fixed square nut and a fastening screw; the helical stepless pressure regulating mechanism consists of a pressure transfer crank, a regulation screw, a locking screw and an air bag; a pressure pin sleeve is arranged at the flurcum contacted with the pressure transfer crank, and pressure regulation is realized by changing the contact height of the pressure transfer crank and the pressure pin sleeve. According to the scheme, compared with the prior art that the cradle installation and fixing and the pressure regulation are separately designed, stepless pressure regulation can be realized by the pressure transfer crank, the pneumatic cradle is simple in structure, convenient and time-saving to operate, firm to fix, consistent in height, convenient and fast in pressure regulation, large in stepless pressure regulation, stable in pressure, good in parallelism and high in the quality of spun yarns, lowers the labor intensity, and has obvious economic benefits.
Description
technical field [0001] The invention belongs to a spinning frame drafting device of textile equipment, and more particularly relates to a lever-type pneumatic cradle pressurizing device for a spinning frame. [0002] Background technique [0003] In the traditional lever-type pneumatic cradle of the drafting and pressurizing device, the cradle is fixed by the upper and lower clamps. Adjust the two connecting screws of the upper and lower clamps to change the rotation of the upper and lower clamps to achieve pressure adjustment. The pressure transmission crank mechanism only The pressure is simply transmitted, and the pressure cannot be adjusted. The fixing and pressure adjustment of the cradle are on the same mechanism, which is time-consuming and laborious. Large, the pressure cannot be kept stable for a long time, the range of adjustable pressure is also small, the difference between spinning spindles is large, the operation is difficult, the labor intensity is high, the ...
