For this working resistance that overcomes the formation of cotton elastic force makes plunger (20) energy fast moving, thereby the effect of performance charging device, technical solutions of the utility model are further characterized in that (accompanying drawing 3,4): be provided with in the main hydraulic cylinder (4) press bag plunger (20) or utilize its bushing pipe (21), the gland (15) of the band sealing ring (16) that connects with plunger (20) end and the cover cylinder structure of tubular plunger (13) composition.Plunger (13) is connected in master cylinder (4) and becomes in the sealing gland (10) of bag working chamber H oil-feed one end, and plunger (13) is the tubular body of inner hollow, and mouth of pipe outer end is communicated with cover cylinder working oil pipe A by gland (10).
Elder generation further illustrates details characteristics of the present utility model, operation principle and course of action in conjunction with the embodiment of press-down type bale of cotton machine (accompanying drawing 3) now: main hydraulic cylinder cylinder body (4) is welded with thick walled steel tube, also available cast steel or high-strength ductile cast iron are cast, its working surface machining accuracy and surface roughness with now ask consistent with the bale of cotton is confidential.End face of this cylinder body connects with the bolt, the nut that become bag working chamber oil inlet end sealing gland (10) to make with modified heat treated No. 45 steel or 40 chromium steel, is embedded with sealing ring (24) in its composition surface.Gland (10) material therefor and cylinder body (4) are roughly the same, gland (10) outer end adopts method indigo plant or gas thread to be connected with cover cylinder working oil pipe A, and gland (10) the inner is then connecting the tubular plunger (13) of shell type oil cylinder with flexible methods such as gas thread or rigidly connected method such as method indigo plant or welding and tube socket, universal spherical joint formulas.One-tenth bag plunger (20) is cylinder iron made or is welded with steel pipe, the internal lining pipe (21) that its common material steel pipe is made can also improve cooling velocity and make its metallographic structure refinement and improve the strength of materials except that constituting cover cylinder housing structure in plunger (20) casting process.Assembling cover cylinder sealing gland (15) with screw (14) on the end face of an end in its cylinder of plunger (20), like this, plunger bushing pipe (21) or directly formed cover cylinder structure in the main hydraulic cylinder (4) by plunger (20), sealing gland (15) tubular plunger (13).Gland (19) is assemblied in the other end of master cylinder (4) with screw.
The topping up pipe C that topping up case (5) and prefill valve (6) are formed charging device makes and directly is installed on the cylinder cap (10) with steel pipe or Reinforced Nylon pipe, can not be installed on the face of cylinder of Master cylinder body H chamber near the A mouth down as if spatial arrangement yet, in addition, the B pipe that is communicated with Master cylinder body (4) (go up top formula bale of cotton machine need not B pipe), D pipe can adopt gas thread to be connected, but the blue formula connection of employing method is then installed more convenient.The utility model institute distribution pipes all adopts the existing material pipeline that uses with pressure stage with bale of cotton machine.
The utility model prefill valve (6) is chosen the component type valve member of commercially available φ 63-φ 115 specifications; Piece number (16), (17), (18), (24) are commercially available standard component hydraulic packing circle, can select V-type, Y for use according to operating mode
xType or O type.
The utility model packing course of work and operating principle are as follows:
Press the bag plunger descending fast: the electromagnet 1CT energising in the electro-hydraulic reversing valve (3), this electromagnetic valve left side position connection work, the right-hand member cavity volume of hydraulic operated valve above the low voltage control oil of pressure source P output enters in the valve (3), its left end cavity volume oil return, hydraulic operated valve right-hand member station connection work, after fluid in the fuel tank (1) entered high-pressure fuel-feed pump (2) by filter screen (22), its pressure oil was by right-hand member station passage, A pipe and cover cylinder plug (13) the back input cover cylinder inner chamber G of hydraulic operated valve.Because tubular plunger (13) is connected on the cylinder cap (10), the internal diameter in cover cylinder G chamber is little far beyond the internal diameter of master cylinder (4), therefore, the pressure of high-pressure fuel-feed pump (2) output directly promotes plunger (20) by the G chamber, overcome the cotton elastic force of precommpression in the lodge and move down fast, master cylinder becomes bag working chamber H volume therefore to increase fast to form vacuum, and the fluid in the topping up case (5) is pushed prefill valve (6) open under atmospheric pressure, the fast master cylinder working chamber H that injects apace finishes the topping up task.
Worker's entrance pressure bag at a slow speed: along with the increase of plunger (20) stroke, the pressed density of cotton constantly increases in the lodge, become the bag compression stress constantly to increase, the output oil pressure of high-pressure fuel-feed pump (2) is corresponding to be increased greatly, when main-cylinder stroke reaches total kilometres 2/3 left and right sides, the G cavity pressure reaches the set pressure in the sequence valve (3 '), sequence valve is opened, the hydraulic oil of oil feed pump (2) output enters master cylinder H chamber by pipeline D, prefill valve (6) is by the positive closing of H cavity pressure oil, the hydraulic oil of oil feed pump (2) output is managed by A, the D pipe enters G chamber and H chamber respectively, and master cylinder (4) cavity of resorption oil return is returned fuel tank (1) from the B pipe through hydraulic operated valve right-hand member station.Because H chamber and G chamber active area sum are far longer than G chamber active area, so the descending at a slow speed pressure bag of plunger (20).This at a slow speed the worker advance the operate as normal speed state that state is now used bale of cotton machine just.
The off-position pressurize: the packing stroke is to assigned position, the ICT outage, solenoid directional control valve is in Y type meta function below the control valve (3), hydraulic operated valve is in M shape meta function because of the equal decompression in end chamber, two ends, master cylinder (4) all pipeline A, B, C, D all are in closed state, press bag plunger (20) pressurize off-position motionless, pump (2) is by the valve road off-load operation of hydraulic operated valve M shape meta function in the valve (3).
Press the up backhaul of bag plunger: make the 2CT energising, low voltage control oil feeds the left end chamber of the upper hydraulic operated valve of control valve (3), its right end chamber oil return, and hydraulic operated valve left end station connection work, pump (2) fuel feeding feeds the cavity of resorption of master cylinder (4) from the B pipe.Because the opened valve port of prefill valve (6) when hydraulic operated valve left end chamber feeds controlled pressure oil, H chamber trapped fuel returns topping up case (5) by valve (6) rapidly in the master cylinder (4), after the pasta superelevation of case (5) by oil return pipe E feeding fuel tank (1); H cavity segment fluid also returns fuel tank by the unidirectional counterbalance valve part (the about 0.4MPa of back pressure) of sequence valve (3 ') the valve road, a hydraulic operated valve left side of flowing through.After up the putting in place of plunger (20), the 2CT outage, plunger is in the off-position packing state again, pump (2) off-load operation.
Fig. 4 has shown another structural shape of the present utility model---go up the embodiment of top formula bale of cotton machine.
The enforcement situation of this structural shape, method, process are consistent with above-mentioned press-down type bale of cotton machine.
Last top formula bale of cotton machine also has some characteristics: master cylinder (4) places in the melt pit more, and fuel tank (1) is installed on the terrace, so the double topping up case (5) of doing of fuel tank (1); Master cylinder (4) belongs to the single-acting formula hydraulic cylinder that relies on plunger (20) to return to the position certainly, and the B pipe only plays the oil return effect, and feeds the H chamber with topping up pipe C, the shared mouth of pipe of order pressure working tubing D; Hydraulic transmission control system is more simple.Now its operation principle, course of action are described below in conjunction with Fig. 4:
The F.F. of top bag: primer pump (2), pressure oil enters cover cylinder G chamber from the A pipe and promotes that plunger (20) overcomes cotton precompressed elastic force and go up the top fast, and master cylinder H chamber forms vacuum, and to push prefill valve (6) open oil-filled in a large number to master cylinder H chamber for fluid in the topping up case (5).
The top wraps at a slow speed that the worker advances: when plunger (20) is gone up about 2/3 total kilometres in top, operating oil pressure constantly increases corresponding rising because of load, when reaching sequence valve (3 ') setting, then pump (2) pressure oil is except that continuing to lead to the G chamber, also enter master cylinder H chamber by valve (3 '), D pipe, because D, C manage connection, prefill valve (6) cuts out, and plunger (20) changes at a slow speed that the worker advances over to.
The off-position pressurize: plunger (20) is gone up after the top puts in place, and pump (2) shuts down, and no pressure oil is imported in the master cylinder (4), and A, C, D, B all seal plunger (20) pressurize off-position.
Plunger whereabouts return: the foot-operated unloader (3 ' " of combined type after pump (2) stall) be operated; under plunger (20) deadweight effect; G chamber trapped fuel and H chamber trapped fuel are managed by valve (3 ' " by A pipe and D, B respectively) returns fuel tank, plunger drops to assigned position, unclamp foot-operated unloader (3), plunger stops.
The utlity model has the outstanding advantages that significantly improves productivity ratio, MDY315 type bale of cotton machine of the present utility model can make the productivity ratio of existing MDY315 type bring up to more than 14 times, stand-alone configuration can be competent at the supporting requirement of packing more than sufficiently on the efficient cotton gin two bench-type production lines of Domestic New. In addition, energy-saving effect brilliance; The master cylinder working oil is is directly charged and discharged by the topping up case, has avoided the caused serious fever phenomenon of compression flow of long period in narrow and long pipe arrangement, and the hydraulic system oil liquid temperature rise reduces greatly, and the complete machine reliable operation, stablize the life-span long, and the manufacturing processing request is not high; Now also can more easily undergo technological transformation with cotton hydraulic baler for this reason.
