Technical Field

The invention relates to a multi-pressure roller pressurizing exchange mechanism.

Background

When the warping machine works, the press roller is pressed on the surface of the warp beam to ensure the winding roundness of the warp beam. The width of the beam determines the width of the press roll. A warper can only generally operate on a beam of one width due to the width limitation of the press rolls. Thus, for an enterprise, several machines are needed for several widths, and the cost and the occupied space are too large.

The roller shaft holes on the rotary type press roller library bracket are arranged on the same circular motion track, so that when the rotary type press roller library bracket is rotated, the original working roller can be replaced by the spare press rollers with other widths, and the effect of replacing the press rollers is achieved; the warehouse support chuck and the gap disc are arranged in a rotating mode, so that the position of the gap on the warehouse support chuck is consistent with that of the gap disc when the compression roller needs to be replaced, and the gap on the warehouse support chuck is staggered with the gap disc gap when the compression roller does not need to be replaced. For better realizing this scheme, be equipped with a plurality of breach on the storehouse support chuck, breach quantity is unanimous with compression roller quantity, and the compression roller passes through breach and breach dish realization and inserts on storehouse support chuck.

The further technical scheme is that three compression rollers are arranged on the rotary compression roller warehouse support, one of the three compression rollers is used as a working roller, the other two compression rollers are used as standby compression rollers, and three roller shaft holes in the rotary compression roller warehouse support are arranged in an annular array.

The further technical scheme is that the library bracket chuck is in an I-shaped disc shape and is rotationally arranged on the compression roller frame, the gap disc is in an annular shape, and a gap for breaking the ring is arranged on the gap disc; the notch on the storehouse support chuck is arranged at the edge of the storehouse support chuck.

A further technical scheme is that the warehouse support chuck comprises a middle cylinder and two side discs fixedly arranged at two ends of the cylinder, the two side discs are of a double-layer structure, each side disc comprises an inner disc and an outer disc, the two discs are fixed on the cylinder, a gap is formed between the two discs, a rubber wheel is arranged between the two discs in a rotating mode, and the notch disc is arranged in a rotating mode relative to the warehouse support chuck through the rubber wheel.

The further technical proposal is that the compression roller pressurizing servo cylinder is an air cylinder or an oil cylinder; the compression roller clamping mechanism is an air cylinder; the driving mechanism is a worm gear stepping speed reducing motor or a servo motor.

The action process is as follows:

1. when the compression roller needs to be replaced, the safety cylinder drives the notch disc to rotate, so that the notch on the notch disc and the notch on the library bracket chuck are located at the same position;

2. the compression roller pressurizing servo cylinder pulls the warp beam pressurizing bracket back, so that the compression roller < working roller > enters the notch;

3. loosening the compression roller clamping mechanisms on the two sides of the warp beam pressurizing bracket;

4. a worm gear stepping speed reducing motor (or a servo motor) rotates the warehouse support chuck, a driving compression roller rotates around the center of the warehouse support chuck, and the operation is stopped and the new compression roller to be replaced is positioned when the new compression roller reaches the notch;

5. the compression roller clamping mechanism clamps the replaced compression roller;

6. the compression roller pressurizing servo cylinder pushes the warp beam pressurizing bracket outwards, and the clamped compression roller is pushed out of the exchange position for warping of equipment;

7. the safety cylinder acts < reset > to close the exchange gap.

The length and the process of the safety cylinder are set according to the initial positions of the notch and the notch disc on the library support chuck.

The invention has the advantages and beneficial effects that: the roller shaft holes on the rotary type press roller library bracket are arranged on the same circular motion track, so that when the rotary type press roller library bracket is rotated, the original working roller can be replaced by the spare press rollers with other widths, and the effect of replacing the press rollers is achieved; the warehouse support chuck and the gap disc are arranged in a rotating mode, so that the position of the gap on the warehouse support chuck is consistent with that of the gap disc when the compression roller needs to be replaced, and the gap on the warehouse support chuck is staggered with the gap disc gap when the compression roller does not need to be replaced. The press roller can be replaced during working, so that the warping machine can be suitable for warp beams with various widths, and the warping machine is ingenious in conception and simple in structure.
