Technical Field

The invention relates to the technical field of pipe cutting related equipment, in particular to a slitting device for a soft pipe.

Background

Different from the traditional hard pipe cutting device, the hose is often fixedly cut by adopting special cutting equipment when being cut due to the characteristics of soft texture and easy deformation of the hose.

The application number "201410223540.6" discloses an automatic hose cutting device, which finally makes a blade extend out to cut a hose under the action of centrifugal force by arranging an inner moving coil and an outer moving coil and by differential rotation of the inner moving coil and the outer moving coil. However, in practical application, due to the difference in material and thickness of the hose, the blade is difficult to cut the hose, for example, for some hoses with slight hardness and thickness, the blade has limited mass and limited centrifugal force, so that the hose is difficult to cut through, and for some hoses with slight hardness and thickness, the blade only deforms the hose when being unscrewed due to lack of support on the inner wall of the hose, so that the hose cannot be cut. In view of this, the present application proposes a slitting device for soft tubes.

The support frame 1 is provided with a fixing device for fixing the hose, and the fixing device comprises two magnetic rings 23, two steel rings 12, two annular air bags 13 and a limiting seat 3; the side wall of the support frame 1 is provided with a fan groove 18, an axial flow fan 19 is arranged in the fan groove 18, the inner wall of the fan groove 18 is provided with an air inlet 21, a first air outlet pipe 17 is communicated with a first telescopic pipe 14 and the fan groove 18, a second air outlet pipe 16 is communicated with a second telescopic pipe 15 and the annular groove 6, and the inner wall of the annular groove 6 is provided with an exhaust hole 11. The position of the fixing device can be kept stable by arranging the magnetic ring 23, the steel ring 12 and other parts, so that the section of the hose 24 can be flat, and the cutting quality of the hose 24 can be improved.

Through setting up fixing device, can support fixedly to the hose 24 inner wall to increase the interact power between cutter 5 and the hose 24, with the assurance can effectually cut off hose 24.

The annular air bag 13 is sleeved outside the steel ring 12, through holes are formed in the side walls of the limiting seat 3 and the support frame 1, the two magnetic rings 23 are embedded in the two through holes respectively, the first telescopic pipe 14 and the second telescopic pipe 15 are welded with the two steel rings 12, the first telescopic pipe 14 and the second telescopic pipe 15 are communicated with the two annular air bags 13, the limiting seat 3 is arranged on the side wall of the rotary cutting ring 2, and the limiting seat 3 is rotatably connected with the rotary cutting ring 2. It should be noted that, by arranging the first extension tube 14 and the second extension tube 15 with adjustable lengths, when the hose 24 passes through the limiting seat 3, the rotary cutting ring 2 and the support frame 1, the passing length of the hose 24 can be adjusted by adjusting the lengths of the first extension tube 14 and the second extension tube 15, so that the hoses 24 with different lengths can be cut. And the first extension tube 14 and the second extension tube 15 are rigid tubes made of hard materials, so that the horizontal heights of the two steel rings 12 can be kept unchanged.

Further, the average diameter of the first extension tube 14 is larger than that of the second extension tube 15, so that the air output of the first extension tube 14 is larger than that of the second extension tube 15 under the condition that the air output of the first air outlet tube 17 is sufficient, and the two annular air bags 13 can be inflated.

Further, still can be through control axial fan 19's rotational speed to the atmospheric pressure of second outlet duct 16 exhaust gas flows is followed in the adjustment, thereby the distance that moves to the left of adjustment sliding ring 7, and then the range and the dynamics of unscrewing of adjustment cutter 5, thereby can be to the hose 24 of different materials and thickness, and it is worth mentioning that, the accessible makes axial fan 19 accelerate gradually, and makes the range of unscrewing of cutter 5 increase gradually, thereby make hose 24 cutting process more convenient, smooth.

The rotary cutting ring 2 is further provided with a rotating device for rotating the rotary cutting ring 2, and the rotating device comprises a synchronous belt 22 and a belt wheel 20. The belt wheel 20 is fixedly connected with the rotating shaft of the axial flow fan 19, and the synchronous belt 22 is used for driving and connecting the belt wheel 20 with the rotary cutting ring 2. Specifically, as shown in fig. 2, the rotary cutting ring 2 is provided with a groove for mounting the synchronous belt 22, so that the synchronous belt 22 can be mounted conveniently.

When the device is used, a hose 24 to be cut sequentially passes through the limiting seat 3, the rotary cutting ring 2 and the support frame 1, then the first telescopic pipe 14 and the second telescopic pipe 15 are extended, so that the two steel rings 12 and the annular air bags 13 respectively extend into through holes in the limiting seat 3 and the support frame 1, and as shown in figure 1, the steel rings 12 are attracted by the magnetic rings 23, so that the horizontal positions of the steel rings 12 are kept unchanged.

Meanwhile, after the axial flow fan 19 is started, air is continuously sucked in from the air inlet 21, and is blown into the two annular air bags 13 from the first air outlet pipe 17 and the first telescopic pipe 14 at a high speed and is discharged from the second telescopic pipe 15 and the second air outlet pipe 16, because the pipe diameter of the first telescopic pipe 14 is larger than the key of the second telescopic pipe 15, the air pressure in the annular air bags 13 is increased, the annular air bags 13 are blown up, so that the inner wall of the hose 24 can be supported, and the hose 24 is fixed.

The air discharged from the second air outlet pipe 16 enters the annular groove 6 and pushes the sliding ring 7 to move leftwards until the exhaust hole 11 is exposed, and as the sliding ring 7 moves leftwards, the screw rod in threaded connection with the threaded hole 8 rotates under the action of the threads, so that the cutting knife 5 can be driven to synchronously rotate and rotate out of the accommodating groove 4 (the movement track of the cutting knife 5 is shown in figure 3), and as the rotary cutting ring 2 rotates, all the cutting knives 5 rotate together, so that the fixed hose 24 can be cut off.

In addition, it is worth mentioning that, because the cutter 5 is made of metal material with good electric conductivity, the two magnetic rings 23 have opposite magnetic poles, and a magnetic field with a horizontal magnetic induction line is generated between the two magnetic rings 23, so that the cutter 5 can continuously cut the magnetic induction line in the rotating process, induced electromotive force can be generated inside the cutter 5, the temperature is raised due to the heat effect of current, the cutter 5 with higher temperature can have higher efficiency in cutting, and the device can also improve the efficiency of hose cutting.
