Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of roving frame, in particular to a roving frame lifting and changing spool device. BACKGROUND

[0002] The roving frame is a spinning machine that makes fiber sliver into roving. The roving frame is divided into wing spindle roving frame and rubbing roving frame according to the form of the twisting mechanism. The wing spindle roving frame continuously applies twist to the sliver by the rotation of the flyer, and produces twisted roving. The rubbing roving frame clamps and rubs the sliver by a pair of rubbing plates to form false twist on the sliver, and produces untwisted roving. The wing spindle roving frame and the rubbing roving frame can be divided into first, second and single pass roving frames. The feeding form, roving package and spindle number of various roving frames are different, but the machine structure and function are basically the same.

[0003] The existing roving frame can lower the spool through the lifting frame after winding the spool, so as to facilitate taking out the spool. However, the existing roving frame cannot work when taking out the spool, and needs to be processed after all the spools are taken out, so as to affect the processing efficiency of the roving frame and reduce the production of yarn. Therefore, we propose a roving frame lifting and changing spool device to solve the above problems. SUMMARY

[0004] The purpose of the present application is to solve the problems in the prior art and provide a roving frame lifting and changing spool device.

[0005] In order to achieve the above purpose, the present application adopts the following technical scheme: a roving frame lifting and changing spool device, comprising a roving frame main body and a lifting spool frame, the bottom end outside of the roving frame main body is fixedly connected with a supporting bottom plate, and the supporting bottom plate is connected with a fixed frame above;

[0006] A plurality of clamping frames are connected in parallel on the fixed frame, a telescopic driving mechanism is arranged on the fixed frame for driving the clamping frame to make telescopic motion relative to the fixed frame, a limiting frame is arranged outside the clamping frame, a clamping mechanism is arranged outside the limiting frame, and a pushing mechanism is installed inside the supporting bottom plate.

[0007] The pushing mechanism comprises an extrusion block, a driving rack is fixedly connected to the bottom end of the extrusion block, a transmission gear is engaged on one side of the driving rack, the other side of the transmission gear is engaged with a driven rack, and a pushing plate is fixedly connected to the top end of the driven rack.

[0008] The line roll is lowered below the main body of the roving frame through the lifting wire frame, the clamping mechanism is moved to the surface of the line roll wound on the surface of the lifting wire frame by the clamping frame, the clamping mechanism pulls out the line roll on the surface of the lifting wire frame, and when the pulled-out line roll is taken out, the clamping frame is retracted by the telescopic driving mechanism, so that the clamping frame drives the extrusion roller to extrude the inclined surface of the extrusion block, the extrusion block drives the rack to retract into the support bottom plate, and the driven rack is moved in the opposite direction through the transmission gear, the push plate is pushed out of the inside of the support bottom plate, so that the line roll pulled out by the clamping frame is lifted.

[0009] Compared with the prior art, the beneficial effects of the present application are: the clamping frame makes stretching movement, the clamping mechanism can pull out the line roll on the surface of the lifting wire frame when stretching movement is made, and when the pulled-out line roll is taken out, the clamping frame is retracted by the telescopic driving mechanism, the push plate lifts the line roll pulled out by the clamping frame, and the clamping frame is retracted by the telescopic driving mechanism, so that the clamping frame is retracted by the telescopic driving mechanism.
