Technical Field

Background

In plastic pipe production, the condition that produced pipes do not meet quality inspection requirements is avoided, and for the unqualified pipes, the pipes are required to be crushed and granulated and then reused, so that the difficulty of granulating the unqualified pipes and the occupied area of workshop unqualified products are reduced, and the unqualified pipes are generally required to be cut into multiple parts.

In conventional pipe cutting, the pipe is cut by manually holding a knife, such as cutting a long tubular pipe into a plurality of short pipes, but this method is time-consuming and laborious. In the prior art, a device special for cutting the pipe is invented aiming at cutting the pipe, for example, a pipe rotary cutting device with the patent publication number of CN217666765U comprises two rotating rollers and a cutting knife, wherein the cutting knife is positioned above the rotating rollers, the two rotating rollers are driven by a motor to rotate, the pipe can rotate through the rotation of the rotating rollers, and the cutting knife completes cutting of the rotating pipe from the upper part of the pipe in the process of rotating the pipe.

When the technology is used for cutting the short-length and light-weight pipe, the pipe is manually moved to be placed on two rotating rollers of the cutting device, but when the pipe diameter of a large-caliber pipe is more than 350mm, for example, the pipe with large caliber has large outer diameter and thickness, so that the weight of the pipe is large, and if a pipe rotary cutting device with the patent publication number of CN217666765U is adopted, the following problems exist:

1. in cutting of large-caliber pipes, the motor is required to drive the rotating roller pressed by the pipes to rotate, so that on the basis of large weight of the pipes, the rotating roller is required to rotate with large energy, and the rotating roller can be driven to rotate only by adopting a motor with larger power, but the purchasing cost of the motor is increased, and meanwhile, the energy consumption for driving the rotating roller to rotate is high.

2. Because the position of the rotating roller is higher, the pipe is difficult to transfer to the rotating roller manually, the pipe can be transferred by means of hoisting equipment, the cost of pipe transfer is increased, the pipe is required to be placed between the rotating roller and the cutting knife, and when the hoisting equipment is used for hoisting, the pipe can not be directly lowered from the space above the rotating roller, and the difficulty of pipe placement is also increased; in addition, when the unqualified pipe is cut, the pipe is required to be cut into a plurality of sections, the pipe is required to be axially moved after each time of cutting, however, under the condition that the weight of the pipe is heavy, the movement of the pipe cannot be basically completed by a single person, and the pipe can still be completed by means of hoisting equipment, so that the cost of cutting the unqualified pipe is increased.
