Abstract

The utility model provides a hose cutting-off device for a pipe cutter, belongs to the machine field, and particularly relates to a pipe cutter for cutting off a hose. The utility model solves various problems that the existing pipe cutter exists when a hose is cut off. The hose cutting-off device for a pipe cutter comprises a cutter fixed on a rotating shaft of a motor, and also comprises a guide nozzle used for the hose to pass through. In the rotating process of the cutter, the cutting edge of the cutter passes through the outlet of the guide nozzle. A container is placed under the cutter, and is filled with lubricating liquid, and in the rotating process of the cutter, the front part of the cutter is contacted with the lubricating liquid. Since the utility model specially aims at cutting off the hose to be designed, the utility model has strong pertinence. Especially, the utility model is provided with the guide nozzle, and can accurately and effectively cut off the hose, and the cut is smooth. The burr in the cut position of the hose can be eliminated by utilizing the lubricating liquid under the cutter.

Description

The hose cutting-off device of pipe cutting machine

Technical field

The utility model belongs to mechanical field, particularly a kind of pipe cutting machine that is used for hose cutting-off.

Background technology

In the flexible pipe production process, plastic flexible pipe is at first extruded the back by the cooler cooling by extruder, needs hose cutting-off at last.Traditional mode of production is to adopt manual mode with hose cutting-off.But because plastic flexible pipe normally is applied on the medical field, so the easy pollution hose of manually-operated, influence the sanitary index of product.Adopting pipe cutting machine to cut off flexible pipe automatically is the development trend that plastic flexible pipe is produced.

Existing pipe cutting machine all cuts off at the rigidity pipe.Therefore, phenomenon produces when utilizing existing pipe cutting machine that plastic flexible pipe is cut off, because of flexible pipe can be shifted, to cause that Pipe Cutting is inaccurate, burr appears in otch out-of-flatness, incision etc., influences the production and the product quality of flexible pipe.

Summary of the invention

The purpose of this utility model is in order to address the above problem, a kind of hose cutting-off device of pipe cutting machine to be provided, and it is specially at the characteristics of flexible pipe and design, and has that otch is smooth, the carrot-free characteristics of incision.

The purpose of this utility model can realize by following technical proposal: the hose cutting-off device of this pipe cutting machine comprises a cutting knife, cutting knife is fixed in the rotating shaft of motor, this device also comprises a guiding mouth that supplies flexible pipe to pass through, in the cutting knife rotation process, the edge of a knife of cutting knife is through the exit of guiding mouth.

Obviously, in the utility model, rotate by the driven by motor cutting knife, will be by the hose cutting-off that transfers out in the guiding mouth.Guiding mouth plays positioning action to flexible pipe, and the phenomenon of flexible pipe skew takes place when preventing to cause the cutting knife Pipe Cutting because of flexible pipe self is soft, and flexible pipe can be cut off smoothly.

In the hose cutting-off device of above-mentioned pipe cutting machine, a container is placed in described cutting knife below, and lubricating fluid is housed in the container, and the front portion of cutting knife touches lubricating fluid in the cutting knife rotation process.

Here, lubricating fluid can play lubrication to cutting knife, makes the incision of being cut flexible pipe not have burr.

Compared with prior art, advantage of the present utility model is it specially at the cut-out of flexible pipe and design, and is with strong points.Particularly be provided with guiding mouth, can be accurately and effectively with hose cutting-off, and otch is smooth.Utilize the lubricating fluid of cutting knife below, can also eliminate the burr of flexible pipe incision.

Fig. 2 is the cross-sectional view of the hose cutting-off device of the pipe cutting machine that provides of the utility model.

Among the figure, 1, cutting knife; 11, the edge of a knife; 2, guiding mouth; 21, through hole; 3, flexible pipe; 4, rotating shaft; 5, motor; 6, lubricating fluid; 7, container.

The specific embodiment

As shown in Figure 1, the hose cutting-off device of this pipe cutting machine comprises the container 7 of cutting knife 1, guiding mouth 2 and a device lubricating fluid 6.Cutting knife 1 is fixed in the rotating shaft 4 of a motor 5, drives by motor 5, and cutting knife 1 is rotated.

As shown in Figure 2, in the present embodiment, guiding mouth 2 is tapered, and there is the through hole 21 that passes through for flexible pipe 3 at its center, and the internal diameter of through hole 21 is slightly larger than the external diameter of flexible pipe 3.Like this, not only make flexible pipe 3 can pass through guiding mouth 2 smoothly, and the displacement of cutting off in flexible pipe 3 processes flexible pipe 3 at cutting knife 1 reduce to minimum limit.

When cutting knife rotated, the edge of a knife 11 of cutting knife 1 cut off flexible pipe 3 through the exit of guiding mouth 2.Obviously, the speed of the rotating speed of motor 5 and delivery hose 3 will determine flexible pipe 3 length cut off.Cut flexible pipe 3 is delivered to subsequent processing by the conveyer belt of pipe cutting machine.

In cutting knife 1 rotation process, can touch lubricating fluid 6 in cutting knife 1 lower reservoir 7 with the edge of a knife 11 of flexible pipe 3 contact portions in the cutting knife 1.In the present embodiment, lubricating fluid 6 is an alcohol.Utilize alcohol to be applied to cutting knife 1 surface, not only make cutting knife 1 cooling, lubricated, and can eliminate the burr of flexible pipe 3 incision.
