Abstract

The utility model provides a decompression structure of a roller head of a papermaking profiling roller. The depression structure of the roller head of the papermaking profiling roller can conveniently and rapidly discharge press oil, effectively seal up lubricating oil in a roller body, ensure that the roller body and an end cap cannot be abraded excessively, and therefore production is reliable. The decompression structure of the roller head of the papermaking profiling roller comprises the roller body, wherein the roller body is installed on a bearing seat through a bearing, end faces of two ends of an outer circle of the bearing respectively contact with sealing caps, the sealing caps are sleeved on the roller body, the sealing cap far away from a power input side is a female maze cap, the tooth-shaped end portion of a male maze cap is matched with the tooth-shaped end portion of the female maze cap to form a maze, a male maze ring is sleeved on the roller body, bonding surfaces of the roller body and the sealing caps are respectively male and female faces at the combination positions of the sealing caps and the roller body, and oil output holes are formed in the lower portion of cap bodies of the sealing caps and at the bottom of the roller body.

Description

The pressure relief of papermaking profile shell roller head

Technical field

The utility model relates to papermaking profile shell roller head technical field, is specially the pressure relief of papermaking profile shell roller head.

Background technology

In the papermaking operation, squeezing is exactly that l Water Paper is guided to one with between two shaping rods of felt, the extrusion of mat shaping rod and the water sorption of felt, l Water Paper is done further dehydration, and make papery tightr, to improve paper, gain in strength, and the water that felt is inhaled enters in the roller by the paper grade (stock) profile shell and discharges from outlet conduit.Roll body Surface Contact paper, the roll body surface has or not greasy dirt, directly have influence on the yield rate of paper, the pressure release oil structure of existing papermaking profile shell roller head, its structure is seen Fig. 1, it comprises roll body 1, described roll body 1 is installed on bearing block 3 by bearing 2, the end face at the two ends of described bearing 2 outer rings contacts with seal cover 4 respectively, described seal cover 4 is set in described roll body 1, near the power input side, the described roll body 1 interior oil discharge pipe 7 that arranges, described seal cover 4 covers described oil discharge pipe 7, the exit, end of described oil discharge pipe 7 arranges shutoff screw 8, the described seal cover 4 of opposite side is female labyrinth lid 5, and the profile of tooth end of described female labyrinth lid 5 and the profile of tooth end of male labyrinth ring 6 complement each other to form the labyrinth, and described male labyrinth ring 6 is set in described roll body 1.This structure is carried out pressure release by at the roll body axle head oil discharge pipe being set, but oil is transported away, and is not easily, and the simultaneously friction between seal cover and the roll body easily causes the wearing and tearing of seal cover, thereby has influence on the normal operation of equipment.

Summary of the invention

For the problems referred to above, the utility model provides the pressure relief of papermaking profile shell roller head, and it is pressure release oil conveniently, and when can realize lubricating oil effective sealing to roll body inside, guarantee that roll body and end cap can overweightly not wear and tear, thus reliable production.

The utility model is realized by following proposal: it comprises roll body, described roll body is installed on bearing block by bearing, the end face at the two ends of described bearing outer ring contacts with seal cover respectively, described seal cover is set in described roll body, described seal cover away from the power input side is female labyrinth lid, the profile of tooth end of described female labyrinth lid and the profile of tooth end of male labyrinth ring complement each other to form the labyrinth, described male labyrinth ring is set in described roll body, the position that described seal cover and described roll body combine, the faying face of described roll body and described seal cover is respectively male and female face, it is characterized in that: in described roll body bottom, described seal cover lid bottom arranges the emptying pipeline.

It is further characterized in that: the male and female face of described roll body and the male and female face of described seal cover are staggeredly arranged.

The beneficial effects of the utility model are, in the roll body bottom, seal cover lid bottom arranges the emptying pipeline, this overall structure can be conveniently from seal cover lid bottom pressure release oil, simultaneously also effectively guaranteed can overweightly not wear and tear between roll body and the end cap, guaranteed normal operation and the normal service life of roll body and seal cover.

Description of drawings

Fig. 1 is the schematic diagram of the pressure release oil structure of existing papermaking profile shell roller head;

Fig. 2 is structural representation of the present utility model.

The specific embodiment

As shown in Figure 2, the utility model comprises roll body 1, roll body 1 is installed on bearing block 3 by bearing 2, the end face at the two ends of bearing 2 outer rings contacts with seal cover 4 respectively, seal cover 4 is set in roll body 1, seal cover 4 away from the power input side is female labyrinth lid 5, the profile of tooth end of female labyrinth lid 5 and the profile of tooth end of male labyrinth ring 6 complement each other to form the labyrinth, male labyrinth ring 6 is set in roll body 1, the position that seal cover 4 and roll body 1 combine, the faying face of roll body 1 and seal cover 4 is respectively male and female face 9, and in roll body 1 bottom, seal cover 4 lid bottoms arrange emptying pipeline 10; The male and female face 9 of roll body 1 and the male and female face 9 of seal cover 4 are staggeredly arranged.
