Abstract
The utility model discloses a double-acting hydraulic cylinder which comprises a cylinder barrel (6), a piston rod (7), a guide sleeve cap (8), a piston sleeve (9), a guide ring (10), a sealing ring (11) and a lock nut (12), wherein the guide sleeve cap is connected to the upper end of the cylinder barrel, the upper end of the piston rod extends out of the guide sleeve cap, the lower section of the piston rod in the cylinder barrel is sleeved with the piston sleeve, and the piston sleeve is sleeved with the guide ring and the sealing ring which are locked and fixed by the lock nut. The hydraulic cylinder disclosed by the utility model solves the problem that the sealing property of an existing piston-type hydraulic cylinder is poor. When a V-shaped piston ring reciprocates in the cylinder barrel, the dynamic sealing property of the V-shaped piston ring is ensured, and the V-shaped piston ring can still normally work when bearing pressure of tens of kilograms, and has air-tight and water-tight effects. During the reciprocating motion of the guide ring and the guide sleeve cap in the piston, the piston ring and the cylinder barrel are in extremely high dynamic concentricity, and further, the dynamic sealing property of the piston ring is improved.
Description
Technical field
The utility model belongs to ice confectionery production equipment technical field, and what relate generally to is a kind of double-lift pressure fluid cylinder.
Background technology
At present, known ice confectionery production equipment all selects automatic colored ice cream production line to be produced (as produced ice cream, baby food made of rice-flour and sugar, ice lolly etc.) mostly.Automatically the nucleus equipment of colored ice cream production line is bottle placer (also claim the material feeding dolly, because bottle placer is equipped with four travelling wheels, can move on the effect yarn track, shape is as dolly, and its function is material feeding, therefore claim the material feeding dolly).The material feeding dolly be equipped with due to automatic colored ice cream production line is divided into two classes, and a class is for annotating solvent or diluents, as water-ice material, milk material, microbulking material.Another kind of for annotating thick material, as puffing material; Mixed slurry; Puffing material mixes with borneol, ice pellets, fruit grain; The hybrid particle slips such as pulp and dry fruit, raisins.Therefore, when producing, need, according to the product difference, select different material feeding dollies.
Fig. 1 is known piston type fluid cylinder, and the rotary valve material feeding dolly used on existing automatic colored ice cream production line all adopts this fluid cylinder, and 1 is cylinder barrel, lower end is that external screw thread is connected with the rotary valve valve body, the cylinder barrel upper end is four circular holes, and 90 degree are uniform, and effect is to hook circular hole dismounting cylinder barrel with the hook special spanner to use, the 2nd, piston rod, cylinder barrel is stretched out in upper end, and piston rod upper end screw thread can be connected with winning in succession, and 3 is piston, 4 is the O RunddichtringO, and 5 is locking nut.During use, when piston rod is up, in cylinder barrel 1, below 0 RunddichtringO, be negative pressure, slurry is flowed in cylinder barrel by hopper, when piston rod is descending, slurry in cylinder barrel is all injected to mould, it is how many that shot is taken out how many notes according to setting value, the piston type fluid cylinder is to seal by 0 RunddichtringO on piston and inner hole of cylinder, and therefore, the sound state sealing of 0 RunddichtringO and cylinder barrel determines the quality precision of material feeding.The main problem existed: 1, four of the cylinder barrel upper end circular holes, when the piston dismounting is safeguarded, 0 RunddichtringO is easily scratched by circular hole, affects sealing and the life-span of 0 RunddichtringO, 2, concentricity is poor, after the dismounting maintenance, the piston rod dynamic airtightness of 0 RunddichtringO and cylinder barrel at the volley is difficult to guarantee, decentraction, sideslip, the wearing and tearing of 0 RunddichtringO will be accelerated, cause at work, piston rod is up to be taken out while expecting, because the mobility of slurry compares differential air, air enters fluid cylinder from cylinder barrel top 0 RunddichtringO, the volume of slurry accounts for, piston rod is descending, during material feeding, slurry can spill from the 0 poor position of RunddichtringO sealing, from the cylinder barrel upper end, miss, 3, efficiency is low, during the up material feeding of piston rod, because slurry can be oppressed the outer surface of 0 RunddichtringO, make the sealing variation of 0 RunddichtringO and inner wall of cylinder, speed is faster, pressure is larger, sealing is poorer, the material feeding precision of piston type fluid cylinder is ± 5 grams, be that tolerance is 10 grams, this is very poor index, in fact quality index is lower.
Summary of the invention
The purpose of this utility model produces thus, proposes a kind of double-lift pressure fluid cylinder.Solve the problem of existing piston type fluid cylinder poor sealing performance, make it there is comparatively ideal performance, can meet the multiple demand of food service industry, can annotate solvent or diluent, can annotate thick material, quality is high, stable performance, speed can be fast or slow, high-low pressure all can work, to enhance productivity, speed is faster, the fluid cylinder internal pressure is larger, while doing the use of spraying nilas machine, can reach tens of kilograms of pressure still can work, double-lift pressure fluid cylinder, when being this fluid cylinder work, key can bear very large pressure, high-pressure and low-pressure can work, during low pressure, device is no wearing and tearing almost, make longer service life.
The technical scheme that realizes that above-mentioned purpose is taked of the present utility model is: a kind of double-lift pressure fluid cylinder mainly is comprised of cylinder barrel, piston rod, guide pin bushing cap, piston bush, guide ring, sealing ring, locking nut, the guide pin bushing cap is connected to the cylinder barrel upper end, stretch out outside the guide pin bushing cap upper end of piston rod, hypomere position at the cylinder barrel inner piston rod is socketed with piston bush, be socketed with guide ring and sealing ring on this piston bush, be locked by locking nut.
The end of sealing ring described in the utility model has groove.
The end of sealing ring described in the utility model has V-groove.
In the reciprocating motion of V-type piston ring in cylinder barrel that the utility model arranges, dynamic airtightness is extremely important, guaranteed that V-type piston ring and cylinder barrel have high dynamic concentricity, guaranteed the dynamic airtightness of V-type piston ring, at the pressure that bears tens of kilograms, still can work, and air tight, water-tight.Guide ring and guide pin bushing cap, in the reciprocating motion of piston, have guaranteed that piston ring and cylinder barrel have high dynamic concentricity, have further improved the dynamic airtightness of piston ring.
