Abstract

FIELD: food industry.

SUBSTANCE: guillotine-type cross-cutting device contains a pneumatic cylinder, linear bearings, guides, fastening, a housing, a toothed blade, a fitting for supplying compressed air, and an electromagnetic valve. When compressed air is supplied to the device through the upper fitting, the pneumatic cylinder rod, where the toothed blade holder is screwed, moves down relative to the body screwed with the mount, cutting through the packaging with the toothed blade. Then, upon receiving a signal from a logical element located in the equipment of the packaging machine, the solenoid valve switches compressed air supply to the fitting to return the toothed blade to its original position.

EFFECT: improved reliability of a guillotine-type cross-cutting device and increased productivity are achieved.

Description

The invention relates to the food industry, namely the meat processing industry, and concerns devices used for packaging finished products.

A packaging machine is known with a heating device, which heats the film web, a forming section, with the help of which packaging trays are formed in the film web and/or in the upper film web, preferably subjected to deep drawing, a filling section, in which the packaging trays are filled with the packaged product, a section heat sealing, which attaches the top film web by heat sealing to the packaging tray, and a longitudinal and/or transverse cutting device that cuts off the manufactured packages, characterized in that it has a porous means to which reduced pressure and/or increased pressure is applied, and/ or transfers energy to the film sheet through thermal conductivity [RU 2015149928].

The disadvantages of this device are the frequent failure of the cross-cutting device, bearing unit and deformation of the blades.

A packaging machine is known that contains a heat-sealing section, which, using a heat-sealing agent, welds the upper film web to the lower film web. Moreover, the heat sealing means has at least one hole connected to a vacuum source and/or a source of replacement gas, and at least one valve for regulating the flow in the hole [RU 2652160].

The disadvantages of this machine are low productivity and design complexity.

The objective of the invention is to increase the reliability of a guillotine-type cross-cutting device and increase productivity.

The problem is solved due to the fact that the guillotine-type cross-cutting device contains a pneumatic cylinder, linear bearings, guides, fastenings, a housing, a toothed blade, and a fitting for supplying compressed air.

The analysis of the level of technology, including a search through patent and scientific and technical sources of information, allowed us to establish that technical solutions characterized by features identical to all the essential features of the declared one were not found, which allows us to conclude that the claimed solution complies with the “novelty” criterion.

The set of essential distinctive features allows us to solve the problem and draw a conclusion about the compliance of the proposed technical solution with the “inventive step” criterion.

In fig. Figure 1 shows a diagram of a guillotine-type cross-cutting device.

A guillotine-type cross-cutting device includes: 1- pneumatic cylinder. 2 - linear bearings, 3 - guides, 4 - fastening, 5 - housing, 6 - toothed blade, 7 and 8 - fittings for supplying compressed air.

A guillotine-type cross-cutting device operates as follows.

When compressed air is supplied to the device in the upper fitting 7, the pneumatic cylinder rod 1, where the toothed blade holder 6 is screwed, moves down relative to the body 5, screwed with fastening 4. Thus, the toothed blade cuts through the packaging.

Receiving a signal from the logical element located in the packaging machine equipment, the solenoid valve switches the compressed air from fitting 7 to fitting 8 to return the toothed blade to its original position.

To achieve smooth cutting of packaging, linear bearings with holder 2 are used, mounted with a rigid connection to the body of the guide device 3, which is screwed onto the upper part of the toothed blade holder. This ensures that the cutting device moves in a straight line relative to the housing during operation.

A guillotine-type cross-cutting device will reduce the failure of this device, equipment downtime and increase productivity. Another feature of this device is that the serrated blade consists of two parts and both are set at an angle of 10 degrees; if you look at the front side, the middle of the knife is much lower than the edges. The advantage of this method is the possibility of uniform cutting, reducing the load on the pneumatic drive, accelerating the cutting process, less resistance from the packaging material and avoiding skewing of the linear guide, as well as subsequent failure of the device. The claimed invention achieves increased reliability of the cross-cutting device and bearing assembly.
