Abstract
The utility model discloses the discharging structure of plastic pipe extruder vacuum shaping box of a kind of gas leakage that makes not easily to leak in vacuum shaping box, vacustat, comprise the adpting flange that sealing is arranged on shaping box casing discharge outlet, adpting flange is provided with rubber gasket and supported flange successively, the center of adpting flange and supported flange is respectively equipped with out material through hole, rubber gasket center is provided with pipe outlet, described adpting flange is connected by some connecting bolts with casing, and the bolt hole on described adpting flange is the elongated hole vertically arranged.
Description
Technical field
The utility model relates to a kind of discharging structure of plastic pipe extruder vacuum shaping box.
Background technology
Plastic extrusion pipe needs through vacuum shaping box cooling and shaping after extruder is extruded.The discharge outlet of vacuum shaping box is provided with the sheet rubber ensureing vacuum shaping box sealing, and sheet rubber is provided with the pipe outlet that size is slightly smaller than undetermined type tubing.During the large minor change of the pipe diameter produced, need to change the sheet rubber being applicable to new tubing.Due to sheet rubber install time, the deviation of the centre of pull occurred unavoidably with the hauling machine be close to, the sheet rubber bearing up-down force of Vacuum shaping discharge outlet can be caused different, after long-time use, stressed part greatly can be worn and torn thus gas leakage of leaking, affect stable vacuum and environmental sanitation that in vacuum shaping box, tubing needs, make vacuum shaping box can not meet normal production requirement.
Utility model content
Technical problem to be solved in the utility model is: the discharging structure of plastic pipe extruder vacuum shaping box providing a kind of gas leakage that makes not easily to leak in vacuum shaping box, vacustat.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of discharging structure of plastic pipe extruder vacuum shaping box, comprise the adpting flange that sealing is arranged on shaping box casing discharge outlet, adpting flange is provided with rubber gasket and supported flange successively, the center of adpting flange and supported flange is respectively equipped with out material through hole, rubber gasket center is provided with pipe outlet, described adpting flange is connected by some connecting bolts with casing, and the bolt hole on described adpting flange is the elongated hole vertically arranged.
As the preferred scheme of one, described supported flange goes out on material through hole and is just provided with circular arc chamfering to the aperture of adpting flange side.
As the preferred scheme of one, seal by arranging rubber slab between described adpting flange and shaping box casing, rubber slab is provided with the discharging opening matched with tubing.
The beneficial effects of the utility model are: because this discharging structure comprises the adpting flange that sealing is arranged on shaping box casing discharge outlet, adpting flange is provided with rubber gasket and supported flange successively, adpting flange is connected by some connecting bolts with casing, bolt hole on described adpting flange is the elongated hole vertically arranged, the position of rubber gasket can be adjusted very easily up and down, make rubber gasket bearing up-down force even, reduce the wearing and tearing of rubber gasket, extend its service life, and then gas leakage of not easily leaking in guarantee vacuum shaping box, that its internal vacuum is stablized.
Just circular arc chamfering is provided with to the aperture of adpting flange side because supported flange goes out on material through hole, avoid the material through hole aperture that of the compacted flange of rubber gasket to cut, and contact surface abrasion is little, extends the service life of rubber gasket.
Owing to sealing by arranging rubber slab between adpting flange and shaping box casing, rubber slab is provided with the discharging opening matched with tubing, defines double sealing, guarantees adpting flange and water tank is air tight leaks, thus guarantees the vacuum of vacuum shaping box.

Detailed description of the invention
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As Figure 1-4, a kind of discharging structure of plastic pipe extruder vacuum shaping box, comprise the adpting flange 2 that sealing is arranged on shaping box casing 1 discharge outlet, seal by arranging rubber slab 6 between adpting flange 2 and shaping box casing 1, rubber slab 6 is provided with the discharging opening matched with tubing.Adpting flange 2 is provided with successively rubber gasket 3 and supported flange 4, the center of adpting flange 2 and supported flange 4 is respectively equipped with out material through hole, rubber gasket 3 center is provided with pipe outlet, described adpting flange 2 is connected by some connecting bolts 5 with casing 1, and the bolt hole on described adpting flange 2 is the elongated hole vertically arranged.Supported flange 4 goes out on material through hole and is just provided with circular arc chamfering to the aperture of adpting flange 2 side.
The above embodiments are the principle of illustrative the invention and effect thereof only, and the embodiment that part is used, but not for limiting the utility model; It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
