Abstract
The utility model provides an improved structure of a plate-type screen changer, comprising a core plate, a discharging sealing ring, a feeding sealing ring, a main body, a filtering screen block, anexpansion ring, a feeding gland and a locating ring; the discharging sealing ring is pressed at the discharging section of the main body, the feeding sealing ring is pressed at the feeding section ofthe main body, one surface of the discharging sealing ring is attached to the core plate, the feeding gland is fixed at the feeding port of the main body, one surface of the inclined surface of the expansion ring is closely attached to the inclined surface of the feeding sealing ring, one surface of the expansion ring, opposite to the inclined surface, is pressed at one side of the feeding gland,one surface of the locating ring is closely attached to the end surface with a groove of the feeding sealing ring, the other surface of the locating ring is closely attached to the feeding gland, theupper end surface of the locating ring is closely attached to the expansion ring, polymers enter in the expansion ring from a gap of the locating ring, and the expansion ring pushes the feeding sealing ring to be closely attached to the core plate flatly after being pressed. The improved structure adopts pressure driving sealing technology, the manufacturing cost is reduced, the operation is safewithout air leakage production, discontinuous filtration is carried out, and the replacement of the filtering screen is easy and rapid.
Description
Technical field:
The utility model relates to film, sheet material, plastic-coated technical field, refers in particular to the structure-improved of the board-like net-changing device of draping under a kind of interruption situation that allows to have in process of production when of short duration.
Background technology:
Board-like net-changing device be comparatively economical also be to require extruding of draping to produce optimal selection for fewer.It is different from single cylindrical net-changing device principle, but there is certain defective in existing board-like net-changing device sealing means, for example, and the leak preventing effect poor effect of system, the shortcoming that the looped network process is cumbersome.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of low cost of manufacture that realizes is provided, handling safety, do not have to lose heart produce, discontinuous filtration, the replacing of filter screen easily, the structure-improved of board-like net-changing device fast.
For achieving the above object, the technical solution adopted in the utility model is: a kind of board-like net-changing device structure-improved, include central layer, the discharging sealing ring, the charging sealing ring, main body, the filter screen piece, oil cylinder, the oil cylinder fixed head, the oil cylinder pillar, protective cover, expansion loop, the charging gland, centring ring, it is characterized in that: the discharging sealing ring is pressed on the discharging section of main body, the charging sealing ring is pressed on the feed zone of main body, the one side of discharging sealing ring is adjacent to together with central layer, the charging gland is fixed on the charging aperture place of main body, the one side on expansion loop inclined-plane is close together with the inclined-plane of charging sealing ring, the one side that expansion loop is relative with the inclined-plane is pressed in a side of charging gland, the one side of centring ring has the end face of groove to be adjacent to the charging sealing ring, the another side of centring ring and charging gland are adjacent to together, the upper surface and the expansion loop of centring ring stick together, polymer enters expansion loop by the slit of centring ring, promotes charging sealing ring plane after expansion loop is under pressure and is close on the central layer.
The utility model adopts the pressure-driven Sealing Technology, makes manufacturing cost reduce, handling safety, the disappointing production of nothing, discontinuous filtration, and the replacing of filter screen is easily, fast.
Description of drawings:
Fig. 1 is the utility model perspective view.
Fig. 2 is the utility model main part structure cutaway view.
Fig. 3 is the local structure for amplifying schematic diagram of Fig. 2.
The specific embodiment:
Referring to shown in Figure 1, present embodiment includes central layer 1, discharging sealing ring 2, charging sealing ring 3, main body 4, filter screen piece 5, oil cylinder 6, oil cylinder fixed head 7, oil cylinder pillar 8, protective cover 9, expansion loop 10, charging gland 11, centring ring 12, discharging sealing ring 2 is pressed on the discharging section of main body 4, charging sealing ring 3 is pressed on the feed zone of main body 4, the one side of discharging sealing ring 2 is adjacent to together with central layer 1, charging gland 11 is fixed on the charging aperture place of main body, the one side on expansion loop 10 inclined-planes is close together with the inclined-plane of charging sealing ring 3, the one side that expansion loop 10 is relative with the inclined-plane is pressed in a side of charging gland 11, the one side of centring ring 12 has the end face of groove to be adjacent to charging sealing ring 3, the another side of centring ring 12 and charging gland 11 are adjacent to together, the upper surface of centring ring 12 and expansion loop 10 stick together, polymer enters expansion loop 10 by the slit of centring ring 12, promotes charging sealing ring 3 planes after expansion loop 10 is under pressure and is close on the central layer 1.
Specify with reference to the operation principle of accompanying drawing net-changing device.The utility model operation principle is: when melt enters net-changing device, the melt-flow major part enters the filter screen piece, and wherein one little melt-flow enters in the expansion loop, because pressure constantly increases, impel expansion loop to expand outwardly, thereby make charging sealing ring bonding central layer tightly.Along with the pressure increase of melt-flow, and the power of adhesive plate is also increasing, the better like this effect that plays leakproof seal.There are two to filter station on this central layer, the operator changes the filtration station of central layer by hydraulic drive, carry out when above-mentioned switching can only descend in the thruput of extruding production line, otherwise will influence the quality of film or cause film to tear, be generally switching time 1 ~ 3 second.
The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
