Description

The invention can be used in the chemical, pharmaceutical, chemical, food industry, as well as in shops and in the public litany system.

A device for cutting llastichnyh materials, such as oils, is known, comprising a housing, cutting lolochok and support walls for entering wires 1 in them.

However, such a device has a complex structure. It is cumbersome, the large tensile forces in the cutting wires make it difficult to cut it.

The aim of the invention is to facilitate the cutting process.

This is achieved by the fact that the intended device is equipped with three drums, mounted rotatably and mutually perpendicularly arranged so that two of them lie in a horizontal plane, and the third is in a vertical one, the cutting wires are fixed at one end to the drums, and device case, while the supporting walls are placed between the drums and the case.

In order to prevent the cutting wires from moving, it is advisable to provide the device with slotted plates, in which the plates are placed between the drums and the supporting walls.

FIG. 1 shows the described device, a general view; n and fig. 2 is a frame for returning the cutting wires to the initial position; in fig. 3 - a wall, located on a drum against longitudinal and horizontal cutting drums; in fig. 4 - kinematic scheme.

The device includes a drum 1 lopechnoy cutting, a drum 2 longitudinal cutting and a drum 3 horizontal cutting. Cutting wires 4 are fastened to one end of the drums, the other end of which is fixedly mounted on the device 5. At the end of each wire there is a loop attached to the hook attached to the device body 5, which makes it easy to disconnect the wires.

The fixed ends of the cutting wires 4, designed for cross-cutting, are fastened on the outer side of the olor wall 6. slightly below the plane on which the monolith 7 is being cut. In this case, the olor wall 6 is located between the drum / and the fixed ends of the cutting wires 4, and the cutting wires 4 in the tensioned state, they are directed along the surface of the supporting wall 6 and enter its slots (not shown in the drawing). The fixed ends of the cutting wires 4, intended for cutting, are fixed slightly below the plane on which the monolith 7 to be cut is installed so that the supporting wall 8 is located between the drum 2 and the fixed ends of the cutting wires 4. In the tensioned condition, the cutting wires , prednaznachennye for longitudinal cutting, directed along the surface of the odor wall 8 and enter into its vertical slots. The fixed ends of the cutting wires, designed for horizontal cutting, are fixed so that the hollow wall 8 is located between the drum 3 and the fixed ends of the cutting wires. In the tensioned state, the cutting wires for horizontal cutting are directed along the surface of the supporting wall 8 and extend into its horizontal slot.

The supporting wall 8 of the barrel is secured to the supporting wall 6. The fixing of the supporting wall 8 in the working position is achieved by using two spring-loaded latches (not shown in the drawing).

The flat horizontal sheet, on which the monolith is being cut, is installed, together with the walls 9 and 10 fixed on it, is a free-moving trolley. The unit is equipped with one or more carts. The cart is mounted on wheels 11.

Wall 10 has through vertical lrrez. Elastic elements 12, which are elastic, for example steel plates, pieces of steel wire or loops made of elastic material, are fixed across each slot at the top and bottom.

On the wall 9 and the device body 5 there are recesses of rectangular cross section. the carriage is fixed in the working position and is a part of the device; a flat recess is formed along the perimeter of the wall 9. In the recess, parallel to its walls and at some distance from them, plate 13 is installed along the entire perimeter with the slot m, and elastic elements 12 across the slots.

In front of the drums 1, 2, 3 there are mounted. Plates 14 with. Slots designed to hold the same distance between the cutting wires 4 when winding the latter on the drums.

Under the drum: M / from the outer side of the cutting wires 4 on the protruding ends of the edges of the device body 5, the rod J5 is placed. To return to the original position of the cutting wires 4, intended for longitudinal and horizontal cutting, the frame 16 is used.

The drive of the device is carried out from one engine. The rotation from the reversing motor 17 through the coupling muff 18 and the descending reduction gear 19 is transmitted to the shaft 20, and then through the bevel gear pair to the drum of the horizontal section 3. 3. The shaft 20 is set on the cheek, 21, transmitting the rotation using a belt. on the pulley 22, mounted on the shaft of the drum 2 longitudinal cutting. Rotation of the drum / cross cutting is transmitted through a conical pair of teeth. To alternately turn on the -drums serve as muffs, for example electromagnetic. Turning off the drums at the end of cutting is automatic with the help of finite 1y; key switches. ,

The device works as follows. The monolith 7 is mounted on the trolley and the support wall 8 folded back. The support wall 8 is returned to the working position, where it is fixed to two spring-loaded and latches.

Then turn on the electric motor 17. And the coupling 23 connecting the horizontal cutting drum 3 with the drive. The cutting wires 4 are tightened, the elastic elements 12 are folded over and the monolith 7 is cut. At the end of the horizontal cutting, the cutting wires 4 go into the horizontal section of the supporting wall 8 and, having closed the contact, turn off the sleeve 23. The longitudinal cutting is switched on, after which the clutch

24 is automatically turned off. The clutch 25 is turned on. Starting and laterally cutting, at the end of which the clutch 25 is automatically switched off. The cart is rolling out. On it, the sliced material is served as intended.

Then install another cart. Having opened the spring latches, fold back the support wall 8. Insert the frame 16. Turn on the clutches 23 and 24. Turn on the electric motor 17 in the opposite direction. As

unwinding the cutting wires 4 from the drums .2 and -5 prodv.igig frame 16 inside the device. After reaching wall 9, frame 16 drives cutting wires 4 by elastic elements 12 and presses the shutdown button

electric motor .17. PaiMKy 16 is removed from the device. Turn off the clutches 23 and 24 and turn on the clutch 25. Grab the rod and turn on the electric motor 17 to unwind the cutting wires 4. As the unwinding of the cutting wires 4 advance the rod ./5. N, turn on the electromotor 17. Take out the rod 15 and install. its in its original position. From the sides of the folded supporting wall 8, the following monolith 7 is placed on the trolley manually.
