Description

A kind of wireline reel

Technical field

The present invention relates to the string dress friction wireline reel that a kind of and mechanical equipment coordination use, especially be fit to be configured in to the cutting of plastics, packing, paper and ultrathin metallic membrane etc., rolling, unreel on the mechanical equipment with rewinding.

Background technology

At present, the domestic and imported wireline reel that uses on the market, it is the rolling mode that adopts air sac or friction-type, because the swelling parts of wireline reel and the internal diameter area of contact of rolling core pipe are little, thereby can not swelling approach and narrower material (as steel pipe and soft plastic pipe), swelling paper tube reluctantly, paper tube is in the coiling working process, can be because the rolling expansive force surpasses the expansive force of swelling rolling paper tube, paper tube will skid on the swelling parts of wireline reel, just having paper scrap drops out, pollution is by coiling material and working environment, and the paper tube surface can not sterilize, so the paper tube high coiling material of hygienic requirements of can not reeling, and the degree of utilization again of paper tube is low, does not meet the requirement of present low-carbon environment-friendly.

Summary of the invention

The object of the present invention is to provide a kind of can the swelling steel pipe and mould pipe, and the wireline reel of the high coiling material of hygienic requirements of reeling.

The technical scheme that realizes above-mentioned purpose is: a kind of wireline reel, it is to be contained on the main shaft by a plurality of packing strings to constitute, described packing comprises guide holder, a plurality of arc shaped sliders and a plurality of friction member, guide holder is sleeved on the main shaft, the left side of guide holder is fixedly connected with first annular cover plate, the right side is fixedly connected with second annular cover plate, has friction ring between the adjacent packing, friction ring is sleeved on the main shaft, have many axial grooves on the periphery of described main shaft, have appendix and fricting strip in the axial groove, appendix is positioned at the bottom of axial groove, the bottom surface and the appendix of fricting strip offset, end face and packing offset, described packing also comprises the outer ring, first reseting spring leaf and second reseting spring leaf, the periphery of guide holder has the oblique slippage section of a plurality of arcs, has primary shaft to annular boss on first annular cover plate, has the second axial annular boss on second annular cover plate, the two ends of described outer ring endoporus are set in primary shaft on the annular boss and the second axial annular boss, have a plurality of slider bore and a plurality of friction members hole on the outer ring, the top of arc shaped slider is inserted in the corresponding slider bore, and arc shaped slider its top when sliding can partly exceed the outside face of outer ring, the oblique slippage section of the bottom surface of arc shaped slider and the arc of guide holder offsets, one end of described first reseting spring leaf is captiveed joint with arc shaped slider, the inner hole wall of the other end and outer ring offsets, described friction member is inserted in the corresponding friction member hole, outer ring, one end of described second reseting spring leaf is captiveed joint with the outer ring, the bottom of the other end and friction member offsets, and the top of friction member exceeds the outside face of outer ring.

Described arc shaped slider has three, and the cross section is "T"-shaped, and described guide holder has three sections oblique slippage sections of arc and three block sections.

The slippage section that the bottom of described arc shaped slider offsets for the oblique slippage section of arc with guide holder, the top has left convex shoulder and right convex shoulder, has screw on the convex shoulder of a left side, one end of first reseting spring leaf is connected on the left convex shoulder by screw retention, also have screw on the right convex shoulder, an end of another first reseting spring leaf is connected on the right convex shoulder by screw retention; The bottom of the slippage section of described arc shaped slider has the axial limiting convex shoulder, and the bottom of described friction member has spacing convex shoulder.

The friction layer that has one deck increase friction force on the arc top surface of described arc shaped slider.

After adopting the structure of technique scheme, during use, withstand fricting strip after the appendix inflation, fricting strip and packing produce friction force, drive packing along with main shaft rotates synchronously, then with the hand steered rolling core pipe of living, make rolling core pipe along with the counter-rotation of main shaft rotation direction, the oblique slippage section of the arc jack-up that this moment, arc shaped slider was directed on the seat is blocked rolling core pipe, and arc shaped slider is on the oblique slippage section of arc during slippage, arc shaped slider can not be stuck, so swelling is solid and reliable, because the internal diameter of the cylindrical that the top constituted of arc shaped slider and rolling core pipe is approaching, friction force is big, also the phase strain is big for fricative expansive force, thus can swelling steel pipe and mould the rolling core pipe that material such as pipe is made, steel pipe with mould tube-surface and can sterilize, can use in the high place of hygienic requirements, can repeated usage, degree of utilization height again, range of use is wide.
