Abstract
The utility model discloses table plate cutting special used knife, comprising a plate shaped knife body triangle knife head, wherein two sides of the knife head are equipped with two corresponding blades, the knife faces of the knife head and the knife body are equipped with a middle gas guide dent, at least one side face of the knife head, and the knife face near the inner edge of the blade edge are equipped with a downward concaved gas exhaustion dent, the gas exhaustion dent and the end portion of the middle gas guide dent are mutually communicated, the knife bodies on two sides of the middle dent are respectively equipped with two communicated gas guide dents. The utility model has the advantages that since the knife face of the knife head is equipped with the downward concaved gas exhaustion dent, the utility model is more convenient for the exhaustion of gas inside the table plate hole, which increases the uniformity of gas flowing inside the hole and improves the processing quality of the table plate.
Description
Technical field
The utility model relates to the cutter that is specifically designed to the cutting grate on a kind of middle plate with grid open cavities extruder production line.
Background technology
On the tinuous production of middle plate with grid open cavities extruder, after grate is extruded moulding, must cut into certain length as required, just can be made into final products then.The synchronous cutting device that generally all has grate in existing on the plate with grid open cavities extruder tinuous production, this device is in the cutting grate, can be along with grate walking forward together, simultaneously, its cutting blade then carries out transverse cuts perpendicular to the direction of motion of grate, thereby realizes the cutting to grate.Because when producing grate, all gas must need be charged in each hole of grate, to prevent that grate from indent taking place in process of production, influence the flatness of plate face, still, when the blade cuts grate, the cutter head of blade and cutter hub partly are easy to block the hole that is cut the place in the grate, make the air pressure in this hole of grate that obviously fluctuation take place, thereby, the smooth and inherent quality of grate plate face influenced easily.At present, ideal method is exactly at the cutter hub of blade and cutter head position and offers the air slot of some outside perforations along the inboard of its blade, when guaranteeing to cut with this, cutter hub and cutter head partly are unlikely to all to block the hole that is cut grate, the obvious fluctuation of hole internal gas pressure when though this blade structure has solved the grate cutting to a certain extent, improved the flatness on the surface when grate is produced, but can't effectively eliminate the influence that above-mentioned cutting blade causes the grate surface when cutting.
Summary of the invention
When the purpose of this utility model is to provide a kind of blade cuts,, improves air communication and cross efficient, guarantee the grate cutting dedicated tool of plate face quality the further influence that improves cutter head to the grate cutting hole.
When further purpose of the present utility model is to provide a kind of grate to be cut, can more effectively eliminate the grate dedicated tool that cutter impacts the plate face.
For realizing the purpose of this utility model, a kind of special cutting blade for cutting lattice plate, comprise the sheet cutter hub triangle cutter head that fixedly fuses, the both sides of cutter head are two corresponding blades, offer the middle air slot of perforation on the knife face of cutter head and cutter hub, offer a recessed air discharge duct at least one side of described cutter head and the knife face near the knife edge inboard, the end of this air discharge duct and middle air slot is interconnected.
For realizing further purpose of the present utility model, a kind of special cutting blade for cutting lattice plate also comprises: the air slot that offers two perforations on the cutter hub of described medial launder both sides respectively.
The beneficial effects of the utility model are: owing to offered recessed air discharge duct on the knife face of blade cutter head part, therefore, during the grate cutting, help the derivation of gas in its hole more, the uniformity of gas flow in the hole when guaranteeing to cut, thereby the plate face quality in improving during plate with grid open cavities processing.
Below in conjunction with accompanying drawing the utility model special cutting blade for cutting lattice plate is further described:
Description of drawings
Fig. 1 is the main TV structure schematic diagram of the utility model special cutting blade for cutting lattice plate;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is along A among Fig. 1---A to partial sectional view.
Among the figure: 1, cutter hub, 2, cutter head, 3, blade, 4, middle air slot, 5, air discharge duct, 6, air slot.
The specific embodiment
Shown in Fig. 1,2 and 3, a kind of special cutting blade for cutting lattice plate, comprise the sheet cutter hub 1 and the triangle cutter head 2 that fixedly fuse, the both sides of cutter head 2 are two corresponding blades 3, offer the middle air slot 4 of perforation on the knife face that cutter head 2 and cutter hub are 1, on two sides of cutter head 2 and knife face, offer recessed air discharge duct 5 respectively near inboard, blade 3 edge, this air discharge duct 5 is triangular in shape, and be interconnected with the end of middle air slot 4, on the cutter hub 1 of medial launder 4 both sides, offer the air slot 6 of two perforations respectively.
In the utility model special cutting blade for cutting lattice plate, usually as long as on the knife face of cutter head 2 one sides, have recessed air discharge duct 5, be provided with the direction of cutter head 2 knife faces of air discharge duct 5 corresponding to the discharge of grate air, facilitate the gas that blows to blade face like this and discharge together, thereby eliminate the influence of airflow fluctuation plate face quality along its air discharge duct 5, middle air slot 4 and air slot 6.
Claims (2)
1, a kind of special cutting blade for cutting lattice plate, comprise the sheet cutter hub (1) and the triangle cutter head (2) that fixedly fuse, the both sides of cutter head (2) are two corresponding blades (3), offer the middle air slot (4) of perforation on the knife face of cutter head (2) and cutter hub (1), it is characterized in that: offer a recessed air discharge duct (5) at least one side of described cutter head (2) and the knife face near blade (3) inboard, edge, this air discharge duct (5) is interconnected with the end of middle air slot (4).
