The utility model is had the advantages that using above-mentioned technical proposal：
The present apparatus is applied to all plastic products extruding production lines, is led in productions such as granulation, tubing, sheet material, film, wire drawings
Domain can apply, and appearance and size is small, simple in construction, reasonable in design, easy to operate, and energy consumption is low, can effectively solve to filter
Net blocks the defects of fast, draping frequency is high.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is sectional view of the present utility model.
Fig. 3 positions left view of the present utility model.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
Reciprocating no net automatic filtering unit as depicted in figs. 1 and 2, it includes feedboard 1, reclaiming plate 2, reciprocating sliding
Device, discharge device, scraper 3.
Feedboard 1 and reclaiming plate 2 are set relatively, are locked by bolt；Screen pack 4 is located on reclaiming plate 2, with filtering
The relative position of web plate 4 is provided with the scraper 3 of longitudinal direction；Reciprocating sliding device and discharge device are respectively provided at the both sides of feedboard 1, scrape
Knife 3 is connected to described reciprocating sliding device, and the position relative with scraper 3 is provided with storage bin 5, storage bin 5 and institute on feedboard 1
The discharge device stated is connected；The position corresponding with cavity is provided with pressure sensor 6 on feedboard 1.
Described reciprocating sliding device is the push-pull device at fixed of fluid pressure type, and hydraulic cylinder 7 is connected to feedboard by pillar bolt 8
