Description

Sawing machine for cutting large-diameter circular tube

Technical Field

The invention relates to a cutting device, in particular to a sawing machine for cutting a large-diameter circular tube.

Background

The plastic pipe production process inevitably produces some defective goods which need to be recycled for reuse in order to reduce the production cost, the defective goods are shredded by a shredder and then ground into powder, and the powder is mixed into raw materials for secondary utilization according to a certain proportion after reaching a certain fineness. Because the diameter of some bore tubular products is too big (be greater than 630mm), the shredder can't shred the defective work of heavy-calibre tubular product, and heavy-calibre tubular product can't shred, just can not get into the crocus link. Because the defective pipes are different in length, diameter and material varieties, the prior art mainly adopts a woodworking band sawing machine or a portable electric saw and the like to manually saw the large-diameter pipes into strips or sheets, and then the large-diameter pipes are sent into a crusher to be crushed, and because the pipes to be cut are different in length, diameter and material, the pipes are very troublesome to operate by adopting a manual mode to cut, and the labor intensity is high and the working efficiency is low.

In addition, for brittle pipes such as PVC and the like, the brittleness of the pipes can be utilized to be broken in a high-altitude falling mode in winter, the pipes are broken into fragments smaller than 630mm by throwing from the high altitude after the weather is cooled, and the pipes are conveniently fed into a shredder. Both of the above methods have disadvantages that the manual sawing has low working efficiency, and once the manual sawing is blocked, people are easily injured. The low-temperature environment of the breaking type crushing mode can only wait for winter, and is only suitable for the pipe with low-temperature brittleness, the stacking period of the unqualified pipe is long, the occupied area of a warehouse is large, and the turnover utilization rate of the warehouse is low.

Patent document CN201792040U discloses an automatic plastic pipe sawing machine, including the frame that sets up along the axial longitudinal extension of waiting to cut tubular product, tubular product slicing mechanism is installed to one end at the frame, this tubular product slicing mechanism includes a confined box, be equipped with the passageway that is used for supplying to wait to cut tubular product to pass through on the box, install the tubular product axial joint-cutting device that constitutes by the saw bit mechanism of cross arrangement in the box, the passageway that corresponds on the box in the frame is fixed with and is used for holding the support mechanism who waits to cut tubular product and through the automatic feeding mechanism of tubular product that is used for the propelling movement to wait to cut tubular product that extends the track sliding assembly that sets up along the frame. This scheme simple structure, convenient operation, low in manufacturing cost need not artifical interference in the work, realize automatic operation completely, and it has not only reduced operation workman's intensity of labour, has improved work efficiency, has still avoided the emergence of the common incident of manual cutting simultaneously. However, the pipe slicing mechanism in the device is only suitable for axis joint cutting, and the actual unqualified pipes are different in length and diameter, so that the application range of the sawing machine adopting the single cutting mode is limited, and the pipe cutting effect is poor.
