Background

currently, the machine industry uses cutting machines to cut materials to mass produce finished products of specific length and shape.

Specifically, as the chinese patent application with the application number of 201510429585.3, a long pipe sequencing feeder and a sequencing feeding method are disclosed, which specifically disclose a rack, a feeding conveyor belt arranged on the rack, a feeding device arranged in front of the feeding conveyor belt, and a bin device arranged behind the feeding conveyor belt, wherein a row of feeding conveyor belts are respectively arranged at least at the left side and the right side of the rack, and each row of feeding conveyor belts comprises a front conveyor belt capable of twisting operation and a rear conveyor belt capable of moving forward in one direction; the front conveyor belt and the rear conveyor belt in the row of feeding conveyor belts are spaced from left to right in a top view, and a partial overlapping area exists between the front conveyor belt and the rear conveyor belt in a side view; the front conveyor belts arranged on the left side and the right side are synchronously arranged, and the rear conveyor belts arranged on the left side and the right side are also synchronously arranged.

The pipe on the feeding device is firstly submitted to the right front conveyor belt, the right front conveyor belt conveys the pipe a to the right rear conveyor belt, and the right rear conveyor belt conveys the pipe a to the bin device. After the pipes fall into the storage bin device, the pipes are stacked into a rectangle in the storage bin.

Because the conveying mode of tubular product makes tubular product take place to warp easily and make the surface unevenness, cause many tubular products before the pipe cutting from this and can't form predetermined shape, and then can't match with the shape of anchor clamps, lead to the unable normal completion of pipe cutting work.

and because the existing pipe cutting machine needs to form a plurality of pipes into a shape matched with the clamp before pipe cutting, the application range of the existing pipe cutting machine is narrow, and the pipe cutting machine cannot be simultaneously applied to circular pipes, square pipes and flat pipes.

in addition, the existing pipe cutting machine adopts vertical feed, the pipe cutting amount is limited by the width of the cutter, and the problem of small cutting amount exists.

in addition, the cutting position (front end of the clamp) of the existing pipe cutting machine protrudes to form a collecting tank for collecting waste materials, which are easy to accumulate and affect normal operation.

It is particularly important in the above-mentioned patent application that the reciprocating conveyor belt is operated at a set frequency at all times and that a similar spacing channel is formed by a rigid spacing rod. This kind of structure can realize breaking up the tubular product that piles up through the cooperation between reciprocating transport belt and the gag lever post. Because reciprocating conveyor's motion mode is more fixed, when the defeated material of tubular product is more, perhaps tubular product is when more in a jumble, tubular product receives the extrusion of gag lever post easily, and tubular product causes the extrusion at spacing passageway entry and makes tubular product impaired, also is not convenient for breaking up of tubular product simultaneously.

Therefore, a feeding machine capable of solving the problems and a pipe cutting production line adopting the feeding machine are provided.
