Description

one

The machine is designed for cutting ribbons, in particular, from artificial leather, for example, for making sandals.

A known machine for cross-cutting a tape, containing a table mounted on the station, a clamp, a cutting element, a gripper for feeding the tapes and a drive. Lever-spring capture of the material in such a machine does not ensure its reliability in operation.

In the proposed machine, in order to improve its Technological capabilities and ensure reliability in operation, the table is installed with the possibility of rotation, has a graduated scale for placing the knife at a given angle, the support for the knife, controlled by the grip. The machine allows you to cut tapes of various shapes and sizes.

FIG. 1 shows schematically the proposed machine for transverse cutting of ribbons; in fig. 2 - turntable machine.

The machine contains guides, lines and / and 2, the distance between which is controlled by a screw clamp 4 for tapes and the upper table 5 with the cutting element. The latter consists of a knife 6 with a movable support 7 and clamp 8.

Behind the cutting element there is a gripper 9 for feeding the ribbons in the form of two jaws, one of which is movable and connected to the air cylinder 10, and the other is also connected to Chi Idrom 10 and carries a wedge 11, a blended Cheater screw with a chain drive 12 and a shaft 13, the screw has a limiter 14 of the stroke of the wedge 11. The cylinder W is in communication with the valve 15.

The table 5 is rotated by means of the handle 16 on the axis 17 in the graduated ring 18, allowing it to be set at a predetermined angle. The knife 6 is driven by an air cylinder 19 communicated with the valve 20.

The movable support 7 communicates through the angular lever 21 with the Pleyba 22 that is movable on the axis 17. The wedge 11 ends interacts with the guide washer 23 and the fixed washer 23 also seated on the axis 17.

The machine works in the following way.

The stack of ribbons is manually loaded between the strips 1 and 2, the spacing with which is adjusted by the screw 3. Next, the ribbons are tucked under the knife 6 onto the support 7. During the process of cutting the tape, the support is opposite the knife. The support is removed from under the knife during the gripping of the tapes and returned under the knife during the feeding of the tapes.

After turning the handwheel 13 of the gripping jaw 9 by means of the chain 12, the ends of the belts under the knife 6 are approached. At the same time, the wedge 11, which walks between the guide washer 23 and the movable washer 22, moves, moving it upwards. Corner lever 21

It acts on support 7, removing it from under the knife and allowing the gripping jaws to clamp the ends of the tapes. In this case, the valve 15 supplies air to the cylinder 10 for carrying out the jaws with sponges and clamping the ends of the belts, and as the handwheel 13 rotates, the belts are pulled to the required length up to the limiter 14. Next, the rotating table 5 is set at a predetermined angle. As a result, I cut the tape blanks with a knife. After this, the cycle of operation is repeated.

The clamp 8 operates from the movable part of the cutting element, and the clamp 4 is designed to hold the belts after trimming and when gripped by the jaws 9.

As a result of the operation of the machine, the ends of the belts are cut at a predetermined angle. The need to change the angle depends on the style and size of the shoe.

Subject invention

A belt cross cutting machine, comprising a table mounted on a bed, an iris, a cutting element, a belt feed grip and a drive, characterized in that, in order to increase its technological capabilities, the table is rotatably mounted, has a graduated scale for setting

knife at a given angle and support for the knife, controlled by grip.
