SUMMERY OF THE UTILITY MODEL

The utility model discloses an overcome the not enough of prior art existence, provide a trade net ware subassembly.

The utility model discloses can realize through taking following technical scheme:

the utility model provides a trade net ware subassembly, includes two ring flanges, perforated plate, supporting shoe, bull stick, U-shaped piece and handle, the terminal surface of ring flange is equipped with two lugs, two the lug sets up relatively the upside and the downside of the terminal surface of ring flange, two form the passageway of the big arcuation in middle of both ends between the lug, two the ring flange sets up relatively, the perforated plate vertically sets up two between the through-hole of ring flange, two are arranged in respectively at its both ends in the passageway, two pass through bolted connection between the ring flange, the one end of supporting shoe is fixed on the terminal surface of ring flange, the bull stick transversely rotates the setting and is in on the supporting shoe, the pot head of U-shaped piece is in on the bull stick, its other end is arranged in between two ring flanges and is stretched into in the passageway, the handle is fixed on the U-shaped piece.

Preferably, the inner side of the bump is arc-shaped.

Preferably, the perforated plate has a cylindrical shape.

Preferably, the side surface of one end of the U-shaped block between the two flange plates is inwards concave to form an arc shape.

Preferably, the number of the bolts is multiple, and the bolts are circumferentially distributed on the flange plate.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses terminal surface at the ring flange is equipped with two lugs, two form the passageway that is used for placing the perforated plate that both ends are big, the middle arcuation is little between, when changing the perforated plate, unscrew the bolt, arrange the import department of passageway in with new perforated plate, pull-down handle drives the U-shaped piece and rotates, make the one end of U-shaped piece press on new perforated plate and remove along the passageway and extrude old perforated plate, screw up the bolt, it is fixed with new perforated plate, make whole trade net process smooth, be difficult to leak material and remaining long-pending material, and overall structure is simple compact, convenient operation.

Drawings

Fig. 1 is a schematic view of the overall structure of the screen changer assembly of the present invention;

FIG. 2 is an exploded view of the screen changer assembly of the present invention;

fig. 3 is a schematic structural view of the flange plate of the present invention;

wherein, the device comprises a 1-flange plate, a 2-perforated plate, a 3-supporting block, a 4-rotating rod, a 5-U-shaped block, a 6-handle, a 7-bolt, a 11-lug, a 12-channel and a 13-through hole.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

Example 1

As shown in fig. 1 to 3, the utility model discloses trade net ware subassembly includes two ring flanges 1, perforated plate 2, supporting shoe 3, bull stick 4, U-shaped piece 5 and handle 6, the terminal surface of ring flange 1 is equipped with two lugs 11, two lug 11 sets up relatively the upside and the downside of the terminal surface of ring flange 1, two form the passageway 12 of the big, little arcuation in centre in both ends between the lug 11, two the ring flange 1 sets up relatively, one of them and extrusion device's export intercommunication, another and melt pump's import intercommunication, perforated plate 2 vertically sets up two between the through-hole 13 of ring flange 1, two are arranged respectively in at its both ends in the passageway 12, perforated plate 2 plays the effect of leaking the net for filter extrusion device's extruded material, two connect through bolt 7 between the ring flange 1, the one end of supporting shoe 3 is fixed on the terminal surface of ring flange 1, bull stick 4 transversely rotates the setting on the ring flange 3, a pot head of U-shaped piece 5 is in on the bull stick 4, its other end is arranged in between two ring flanges 1 and is stretched into in the passageway 12, handle 6 is fixed on U-shaped piece 5. When the extrusion device works, the material is discharged from the outlet of the charging barrel of the extrusion device, filtered by the porous plate 2 and then conveyed to the melt pump. When needs change perforated plate 2, the unscrewing bolt 7 makes two ring flanges 1 be in the relative state of loosening, put into the entrance of passageway 12 with new perforated plate 2, pulling handle 6 drives U-shaped block 5 and rotates, make the lower terminal surface of U-shaped block 5 press on new perforated plate 2 and with new perforated plate 2 inside extrusion slip, make new perforated plate 2 extrude old perforated plate 2 and arrive the position location after, the tightening bolt 7 locks two ring flanges 1 again, whole screen changing process is difficult to leak material and remaining long-pending material, and overall structure is simple compact, convenient operation.

In this embodiment, the inner side of the protruding block 11 is arc-shaped, and the porous plate 2 is cylindrical, so that when the porous plate 2 is replaced, the two protruding blocks 11 of the porous plate 2 can slide in the channel 12. The side surface of one end of the U-shaped block 5 between the two flange plates 1 is inwards concave to form an arc shape, so that the U-shaped block 5 can push the porous plate 2 to slide conveniently. The quantity of bolt 7 is a plurality of, and is a plurality of bolt 7 is the circumference distribution on ring flange 1, makes locking more firm between two ring flanges 1, and the atress is more even.

The present invention has been described in connection with the preferred embodiments, but the present invention is not limited to the above disclosed embodiments, and shall cover various modifications, equivalent combinations, according to the essence of the present invention.
