Abstract
The utility model discloses an automatic pressure-distributing lubricating piston of a filling device. The automatic pressure-distributing lubricating piston comprises a cylindrical piston body, the front end face of the piston body is a bearing pressure bearing surface contacted with filling materials, the lateral wall of the piston body is an annular outer wall in sliding matching connection with the inner wall of a material barrel, at least two sealing ring installation grooves are arranged on the annular outer wall, a sealing ring is arranged in each sealing ring installation groove, the rear end of the piston body is a piston rod connection end, the piston body is provided with a flow guiding through hole which begins from the pressure bearing surface of the piston body and ends on the annular outer wall of the piston body, and an outlet of the flowing guiding through hole on the annular outer wall of the piston body is arranged between the two adjacent sealing ring installation grooves. In working, pasty fluid of the material barrel enters between the two sealing rings from the flowing guiding through hole so as to distribute the pressure of the paste fluid to the rear sealing ring and enable the two sealing rings to bear the pressure of the pasty fluid together, accordingly, the condition that the front sealing ring bears the whole pressure of the pasty fluid is effectively improved, the lubricating effect of the pasty fluid enables the piston to be flexible in rotating, and the service life of the automatic pressure-distributing lubricating piston is prolonged.
Description
Technical field
The utility model relates to a kind of piston, is specifically related to the piston of the filling apparatus of a kind of solution for can cosmetics, food, material body or paste.
Background technology
In the prior art, the piston type filling apparatus that food, cosmetic industry use generally includes barrel, piston, piston rod and piston driver, piston is arranged in the barrel, the sidewall of piston is provided with at least two seal ring mounting grooves, be provided with seal ring (piston ring) in the seal ring mounting groove, the sidewall of piston cooperates with the inwall slipper seal of barrel by above-mentioned seal ring, the front end face of piston is the load bearing face that contacts with the can material, piston rod is fixedly connected on the rear end of piston, and piston rod is connected with piston driver.During work, the piston driver driven plunger is reciprocating in barrel, thereby extracts pressing materials out, finishes can.
Yet, in existing filling apparatus, owing to do not have lubrication mechanism between piston and the barrel, in the course of the work, seal ring is in the dry grinding state always, and the pressure between piston and the barrel more the wearing and tearing of large sealing packing ring are just more serious, this has shortened the service life of piston and filling apparatus greatly so that seal ring is crossed quick-wearing.
The utility model content
The deficiency that the utility model exists in order to overcome prior art provides a kind of automatic dividing potential drop lube pistons with filling apparatus of rational dividing potential drop lubrication mechanism, and this automatic dividing potential drop lube pistons can effectively prolong the service life of piston and filling apparatus.
The utility model is achieved through the following technical solutions: a kind of automatic dividing potential drop lube pistons of filling apparatus, comprise columned piston body, the front end face of described piston body is the load bearing face that contacts with the can material, the sidewall of described piston body is the annular outer wall with the material tube inner wall sliding connection, described annular outer wall is provided with at least two seal ring mounting grooves, be provided with seal ring in the seal ring mounting groove, the rear end of described piston body is the piston rod coupling end, described piston body is provided with the water conservancy diversion through hole that leads to the annular outer wall of this piston body from the load bearing face of this piston body, described water conservancy diversion through hole in the outlet on the annular outer wall of described piston body between two adjacent seal ring mounting grooves.
The annular outer wall of described piston body is disposed with the first seal ring mounting groove, the second seal ring mounting groove and the 3rd seal ring mounting groove from front to back, described water conservancy diversion through hole in the outlet on the annular outer wall of described piston body between described the first seal ring mounting groove and described the second seal ring mounting groove.
The beneficial effects of the utility model are: in working process of the present utility model, when piston pressurizes to material movement, lotion in the barrel enters between two seal rings by the pod apertures of piston, lotion fills up two spaces between the seal ring, exert pressure for a rear seal ring, give a rear seal ring with the pressure distribution of lotion, the situation of only having last seal ring to bear the whole pressure of front lotion of the prior art is changed into the pressure of two seal ring shared lotions, effectively reduce the pressure that last seal ring bears, the wearing and tearing of last seal ring have been reduced, lotion has played lubricating effect between two seal rings simultaneously, filling apparatus is gone slick, avoid dry grinding, prolonged service life.
