The rack and the machine frame conduct rolling friction, so that running resistance of the lower keel in up-and-down moving is greatly reduced, the problem that when the lower keel operates up and down, creeping and pausing phenomena happen is solved, working stability of up-and-down operations of the lower keel is improved, the running resistance of the lower keel is reduced at the same time, a balance weight machine can be removed, the whole machine cost is reduced, the structure is simple, the construction cost is low, and guarantees are provided for spinning high-grade roving and forming.
Description
Technical field
The utility model relates to a kind of down rail elevating mechanism of automatic doffing Speed frames, belongs to automatic doffing Speed frames technical field.
Background technology
The automatic doffing Speed frames are automatically finished to replace tubes, repiece, driving from doffing, and have realized the full-automatic spinning of Speed frames and thickness connection, make the cotton spinning spinning can further improve spinning quality, and increase substantially productivity ratio and reduce labour intensity.The automatic doffing Speed frames spin or blending for general comb and the pure of combed cotton fiber type and artificial fibre at present, and with the feeding of mixing in doubling step grown place sliver, the spinning rove uses for spinning process.
Full-automatic doffer is after spinning the rove of full certain-length, and down rail drops to the position of doffing behind the automatic stopping, get full yarn and and place blank pipe, down rail resets behind automatic doffing and replace tubes, the automatic joining seam of automatic doffing Speed frames rove forms new round spinning.The automatic doffing Speed frames will be asked for full yarn and blow-down pipe, so down rail need frequently be done and pumps.Down rail is mounted on the transverse slat of down rail stand-off, and down rail stand-off and lever shaft join and along its rotation, the down rail stand-off is connected with tooth bar, move up and down by the gear drive tooth bar, but the guide pad of the rectangular bar shaped at these tooth bar two ends is arranged in the gathering sill of frame, when the down rail stand-off moves up and down along frame, the guide pad of tooth bar and gathering sill are the plane hard friction, because the frictional force when down rail moves up and down is big, it is big not only to drive the power requirement, and balancing counterweight mechanism need be arranged, its down rail stand-off is by chain and is connected with counterweight through hinge wheel and minor sprocket, and need reach the weight that be connected other part with it and the weight of the balancing weight behind the car is complementary according to the down rail before the car.Because guide pad and gathering sill on the tooth bar are planar friction, thus when tooth bar when moving up and down, down rail also the phenomenon of creeping and make a pause can occur, thereby influences the job stability of down rail.
Summary of the invention
The utility model purpose provides a kind of frictional resistance can reduce down rail and move up and down the time, reduces the down rail elevating mechanism of the automatic doffing Speed frames of complete machine cost.
The utility model is that the technical scheme that achieves the above object is: a kind of down rail elevating mechanism of automatic doffing Speed frames, it is characterized in that: comprise being installed in the gear shaft that has gear on the frame and the tooth bar that meshes with gear, described gear shaft is connected with motor, tooth bar is connected with the down rail stand-off, be connected with down rail on the transverse slat on the down rail stand-off, described tooth bar is connected with at least two rollers, and roller is arranged on the gathering sill of frame and can moves up and down along gathering sill.
Gear shaft of the present utility model is connected with motor, can pass through the positive and negative rotation of motor-driven gear axle, thereby drive tooth bar, the upper and lower motion of down rail stand-off, because tooth bar is provided with roller, roller is arranged in the gathering sill and along gathering sill moves up and down, therefore roller when moving up and down is and the gathering sill rolling friction, therefore reduced the running resistance when down rail moves up and down significantly, solve the phenomenon of creeping and make a pause that down rail occurs when upper and lower operation, improved the job stability when down rail moves up and down.The utility model can be cancelled balancing counterweight mechanism owing to can reduce the running resistance of down rail significantly, reduces the complete machine cost, and simple in structure, improvement cost is low, provides safeguard for spinning out high-grade rove shaping.
