(54) DEVICE FOR THE MODE OF CARTON-MOBILE PIPE

The invention relates to tarot production equipment, namely, devices for cutting a cardboard-rolled pipe.

A device for cutting a cardboard-wound pipe containing a mandrel, a clamping mechanism having a housing, a cutting head with circular knives mounted on sliders, having means for radial movement and a drive are known.

However, such a device makes it possible to cut the pipes in two steps, i.e., first partially cut the pipe in diameter, and then make the final finishing cut.

The purpose of the invention is to improve the performance of the device.

For this, a cutting head is coaxially mounted inside the mandrel, and the clamping mechanism is provided with a flexible brake band and a supporting annular blade mounted on the inner surface of the housing.

The means for radial movement of the sliders consist of double-arm levers with rollers located at one end, spring-loaded dogs attached to i

the other end, and the cone mounted inside the mandrel and and interacting with the rollers of the levers.

FIG. 1 shows the proposed device for cutting a cardboard-rolled pipe, general view; in fig. 2 is a section along A-A in FIG. one.

The main working parts of the pipe cutting device are the cutting head 1. The cutting head is fixed on the shaft 2. The shaft is mounted in movable floating bearing housings 3 and is driven into rotation by an electric motor 4. The head consists of circular knives 5i mounted on its shafts mounted in bearings floating sliders 6, interconnected by a spring 7 and placed in the housing 8. In the housing are mounted levers 9 with spring-loaded pawls 10 and rollers 11 supported on the copier 12, fixed in the mandrel 13, with oh skhovdit navivaema cardboard tube 14

The clamping mechanism has a brake flax

| That 15. The mechanism is installed in HanpaBj-2525 Lll

16 and is driven in reciprocating motion by an pneumatic cylinder 17 mounted on a frame 18.

The brake tape is fixed on axis 1 in a rotating case 20. The case is placed in the groove of the stand 21 and held by the carrier flange 22., supporting ring knife 23, for disk knives 5 and circular electric boards 24, which by means of movable contacts 25 installed in

 body 20 form ueiu. an electromagnet 26 acting on a flexible brake band 15, tightening it on a cardboard tube 14.

The cutting head, the brake tape 15 and the electric motor 4 mounted on the movable plate 27 connects the shroud 28 of the pneumatic cylinder 17, at the end of which a locking swivel wedge 29 is installed, which interacts with the closing groove of the movable plate 27.

The device for cutting the pipe works as follows.

The rolled cardboard tube 14, rotating, is removed by straps from the fixed mandrel 13 to the side shown in FIG. 1 with an arrow, and, having reached the end switch 30, connects the circuit of the electromagnet 26 and the circuit of the electromagnet of the air distributor. Air is supplied to the pneumatic cylinder 17. At the same time, the brake tape 15 clamps the pipe 14. The housing 20, rotating together with the pipe, moves under the action of the pneumatic cylinder 17 by the force of the removable cardboard pipe. Together with the brake band, the cutting head also moves. In this case, the rollers 11, rolling up on the copier 12, by means of the levers 9 and the dogs U, move the sliders 6 apart, and together with them the disk knives 5, which radially move apart towards the center of the cutting head, cut the pipe 14, resting the outer part of the pipe on the supporting annular knife 23. Cut labor. The ba-shell of the drum falls on the tray illa transport device. The cutting head continues to move until the pawls 10 come off the sliders 6. After the sliders, together with the disc blades 5 return to the starting position under the action of the spring, the electromagnets are turned off. The cutting head and the clamping ring are returned to their original position.

At the time of launching the device for discharging the brake tape 15 forward with respect to the cutting head, the stroke of the pneumatic cylinder 17 is increased relative to the cutting head. In order to retract the brake band 15, the wedge 29 must be pulled out of the groove and the compressed air must be fed into the cavity necessary for this.
