Abstract
The utility model provides a vacuum back-suction leak-proof filling head. The filling head is formed by connecting a cylinder body with a filling head body through a cylinder fixing nut and a locking nut, a flat gasket seal ring is installed at the position where the locking nut and the filling head body are connected, and the filling head body and a feed inlet are fixed together through welding. A cylinder piston rod which is a hollow piston rod is arranged in the cylinder body, the cavity in the cylinder piston rod is a piston rod back-suction hole, one end of the cylinder piston rod is connected with a filling head inner plug, an inner back-suction hole communicated with the cylinder piston rod back-suction hole is formed in the central cavity of the filling head inner plug, the head of the filling head inner plug and an outlet of the filling head body are tapered, and an O-ring is arranged in a circular groove of the lower taper face of the filling head inner plug. The vacuum back-suction leak-proof filling head is concise and compact in appearance, the problem of leakage of liquid is solved thoroughly, the filling accuracy is improved, and the filling head has good economic and social benefits.
Description
Technical field
The utility model belongs to the filling machine technical field, specifically with bottle placer, is used in conjunction with, and is used for the filling head of a kind of vacuum resorption antidrip of filling fluid.
Background technology
Present liquid packing device, for example in the liquid-filling machine process of reproduction due to the structure problem of filling head, when the filling conversion of two packaging bags, have drip problem.The filling liquid of water clock not only causes the pollution to product, has also affected the filling accuracy of product.
Adopt the filling head with vacuum resorption function in existing equipment, its resorption outlet, in the side of filling body, communicates with the resorption hole of plug side in filling head, and the resorption hole at the resorption Kong Yuqi center of interior plug side communicates.In filling head, plug is free-running fit with the fit system of body liquid outlet, and seal ring is equipped with at upper step place, resorption hole, and liquid is non-leakage when guaranteeing that filling head is closed.There are two problems in this filling head: because there is gap in plug in filling head with the cooperation place of body, will there be gap in the junction, resorption hole of the resorption hole of interior plug and body, so just causes vacuum resorption efficiency not high, and liquid has water clock; When plug decline was closed in filling head, very large shearing force can be born in the seal ring cross section at upper step place, resorption hole, causes seal ring shorter service life, and the user needs often to change.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and the filling head of a kind of vacuum resorption antidrip that a kind of compact conformation is simple, be skillfully constructed is provided.
The technical solution of the utility model realizes in the following manner,
The filling head of a kind of vacuum resorption antidrip, its structure is to be linked into an integrated entity by cylinder captive nut and jam nut by cylinder block and filling body, the plain cushion seal ring is installed in jam nut and filling body junction, and filling body and inlet point are welded and fixed and are integrated.
As preferably, being provided with cylinder piston rod in described cylinder block is hollow piston rod, the cavity of cylinder piston rod inside is piston rod resorption hole, one end of cylinder piston rod is connected with plug in filling head, be provided with in the central cavity of filling in filling head one be connected with cylinder piston rod resorption hole in get back into sucker.
Further, in described filling head, plug head and filling body exit are tapered, in the annular groove of plug lower taper face, the O RunddichtringO are housed in filling head.
working process of the present utility model is: when filling head is opened, cylinder piston rod is retracted, rise beyond the Great Wall in the filling head that drive is attached thereto, liquid enters into filling intrinsic filling head cavity body from inlet point, flow out from the conical discharge port of filling head cavity body bottom again, when filling when complete, cylinder piston rod stretches out, in the filling head that drive is attached thereto, plug descends, filling head is closed, taper fit face and O RunddichtringO have guaranteed that liquid is non-leakage, simultaneously, the suck back valve that control system will be connected with the cylinder piston rod other end is opened, fill in residual bottom liquid in filling head and be inhaled into piston rod resorption hole, in get back into sucker, avoided liquid drip leakage.
The beneficial effect that the utility model compared with prior art produces is:
The filling head of a kind of vacuum resorption antidrip of the present utility model, outward appearance is succinct, compact,, by connecting the resorption hole of cylinder piston rod and filling Nei Sainei, forms straight-through and seal a resorption hole, thereby reach best resorption effect, solved the water clock problem of liquid; In filling head, plug bottom and filling body liquid outlet place adopt taper fitting, fitting surface mounting O-shaped seal ring, make sealing more reliable, also greatly extended the service life of O RunddichtringO, ten thousand time be increased to 30 ten thousand time or more from original 3-5 the service life of seal ring; Simultaneously, shorten the stroke of cylinder, reduced filling head and closed the needed time, thereby improved filling accuracy, had good economic benefit and social benefit.
