Description

The squash type briquetting press

The utility model relates to a kind of briquetting press, particularly a kind of squash type briquetting press that produces extruding force.

Present existing briquetting press by motor through decelerator drive two in relative rotation roller form, the uniform respectively half mould groove that forms coal briquette that impels on the outer surface of roller, form the complete machine coal briquette when horizontal level is in contact with one another and close and disturb groove when the half mould groove of two rollers forwards to simultaneously, and coal dust in the groove is bonded together becomes coal briquette, turning over horizontal center then comes off automatically, export by conveyer belt, coal dust is the space region that is introduced into two roller tops through coal bunker, enters the half mould groove of two roller surface more respectively.

The shortcoming of this briquetting press is: 1, because coal dust is to enter two space region between roller, after filling up space region, promptly form dead coal district, the coal dust that forms the sliding friction face in roller surface is difficult for directly going into half groove, these coals produce a coal dust bed course at the sliding friction face, increase resistance, waste energy.2, the coal dust that can enter half groove also is loose powder, when two sides, half groove forwards the level position to and contacts, owing to there is not pressure, makes in the groove not easy-formation of coal dust, and fragmentary coal briquette is more, inefficiency.

The purpose of this utility model is a kind of squash type briquetting press of developing at the deficiency of above-mentioned existing briquetting press existence.It is to be furnished with the half mould groove at two in relative rotation on one of them cylinder, is furnished with through hole on another cylinder, and the half mould mould that can move and can produce certain pressure is housed in each through hole.What impel half mould mould motion generation extruding force is: the camshaft that cam is housed, camshaft and cylinder are not centres of gyration, but in same horizontal plane, be offset a segment distance mutually, therefore the half mould groove that is contained in the drum through hole is different with the movement locus of cam, so peak of cam, only a certain exhausting hole at two cylinders forwards the level position to, the generation extruding force just can promote the half mould mould to raise when being in contact with one another this position, realize forcing extrusion modling, the charging coal bunker is the vertical center line top that is contained in cylinder, utilizes the deadweight of coal dust can fill up the coal tube smoothly.

The utility model is to implement like this: motor 1 through decelerator 2, by pinion 3, drive that gear wheel 4 makes camshaft 5 and the cam 6 that is contained on the camshaft 5 rotates together, the little change-speed gearing 7 that is fixed on simultaneously on the camshaft drives two cylinders 12 and relatively rotates by big change-speed gearing 8, axle 9, pinion 10, gear wheel 11, and the half mould mould 13 that is contained in the drum through hole rotates along fixation locus with cylinder together.Because the half mould mould 13 that is contained in the drum through hole is not a centre of gyration with cam, be at same horizontal plane bias internal one segment distance, so movement locus difference, thereby guaranteed that cam peak A only just can raise little liter wheel 14 and half mould mould 13 in the level position, motion produces extruding force in drum through hole, realizes the coal dust in the through hole is forced extrusion modling.When the half mould mould 13 in the holes of drum and cam peak A turn over the level position simultaneously, because cam speed is faster than cylinder, peak A leaves half mould mould 13, little liter wheel 14 very soon, rotate along fixation locus, at this moment half mould mould 13 self-return under spring 15 effect, treat down that the peak A of cam also just in time forwarded level to when row was with the holes of drum of half mould mould to go to the level position, make 13 motions of half mould mould produce extruding forces by little liter wheel 14 once more.Coal bunker 16 is contained in the vertical line top of cylinder.

Good effect of the present utility model is:

1, of the present utility model two in relative rotation one of them cylinder of cylinder be furnished with through hole, in each through hole, all be equipped with and can move and can produce the half mould mould 13 of certain extruding force; Be equipped with corresponding half mould groove on the another one cylinder.

What 2, impel that half mould mould 13 motion produces extruding forces is the camshaft 5 of cam 6 to be housed and to take turns 14 with the little liter that cam 6 touches mutually.The camshaft 5 and the cylinder 12 of stationary cam 6 are not centres of gyration, but at same horizontal plane bias internal one segment distance L, and only just the half mould mould can be promoted rising generation extruding force at the peak A of horizontal position, cam.

3, the self-return of half mould mould 13 is realized by compression spring 15.

Description of drawings:

Accompanying drawing 1 is the broken section structural representation of the utility model squash type briquetting press.

Accompanying drawing 2 is the utility model extruding briquetting press side-looking broken section structural representations.

Wherein: 1 in the accompanying drawing, motor 2, decelerator 3, pinion 4, gear wheel 5, camshaft 6, cam 7, little change-speed gearing 8, big change-speed gearing 9, axle 10, pinion 11, gear wheel 12, cylinder 13, half mould mould 14, little liter wheel 15, spring

Below in conjunction with accompanying drawing the utility model is described in further detail:

As shown in drawings: motor 1 passes through pinion 3 through decelerator 2, gear wheel 4 makes camshaft 5 and the cam 6 that is contained on the camshaft 5 rotates together, the little change-speed gearing 7 that is fixed on simultaneously on the camshaft 5 passes through big change-speed gearing 8, axle 9, pinion 10, gear wheel 11 drives two cylinders 12 and relatively rotates, the half mould mould 13 that is contained in the drum through hole moves along fixation locus with center of circle O with cylinder, the cam 6 that is contained on the camshaft 5 moves along fixation locus with center of circle O1, because half mould mould 13 is not a centre of gyration in cam 6, but at same horizontal plane bias internal one segment distance L, so cam peak A only just can promote half mould mould 13 to rise in horizontal position through little liter wheel 14, produce extruding force, realize forcing extrusion modling.When the peak A of half mould mould 13 and cam 6 turns over horizontal level simultaneously,,, coal briquette is come off automatically up to all leaving because the circular motion of cylinder makes the contact gap between the moulding coal briquette become big gradually from compressing; Simultaneously, because the cam rotating speed is faster than cylinder, peak A leaves little liter wheel 14 very soon, move along fixation locus, at this moment half mould mould 13, little liter take turns 14 under spring 15 effects, self-return, still by former fixation locus motion, coal bunker 16 is contained in the vertical center line top of cylinder.
