Problems solved by technology

Disadvantageously, interfering geometries partially occur in this main line
Furthermore, in known suction devices, disadvantageously, non-uniform velocity and pressure ranges occur in the main line and in the individual suction elements, which is undesirable or to be avoided because, for example, such a risk arises , i.e. the suction equipment may be clogged due to waste products, or the waste products that arise cannot be reliably sucked out of the production machine, especially from the suction space

Embodiment Construction

[0048] figure 1 A device 1 for suctioning off waste products 2 of a production machine 3 is shown. The production machine 3 may be a machine for the manufacture of flexible packaging elements, in which waste products 2 occur during production, from which waste products 2 are to be removed, because otherwise they may be produced during production or in the production machine 3 Unexpected interference during operation. The production machines 3 may be blown and cast film equipment, flexographic and gravure printing presses, machines for refining and treating paper, film and plastic fabrics, or packaging machines. The waste product 2 can consist of plastic or paper. Here, the surface properties of the waste product 2 may vary. For example, it is conceivable that the waste product 2 is sticky and / or matte and / or smooth.

[0049] For the purposeful removal of these waste products 2 from the region of the production machine 3 , a device 1 for suctioning out the waste products 2 ...

Abstract

The invention relates to a device (1) for suctioning off waste products (2) from a production machine (3), in particular from a sheet extruder, comprising a suction chamber (10) on which at least one suction element (20) is arranged, said suction element extending into a suction space (4) located outside the suction chamber (10) in order to convey waste products into the suction chamber (10), and comprising a suction unit (5) to generate a negative pressure in the suction chamber (10). According to the invention, a sealing means (40) that rests against the suction element (20) and seals the suction chamber (10) is designed in such a way that the suction element (20) can move along the sealing means (40), thus enabling the position of the suction element (20) on the suction chamber (10) to be variably adjusted.

Description

technical field [0001] The invention relates to a device for suctioning waste from production machines, in particular film extruders, comprising a suction chamber and a suction unit for creating a negative pressure in the suction chamber, on which at least A suction element extending into the suction space outside the suction chamber in order to convey the waste products into the suction chamber. Background technique [0002] Various suction devices are known from the prior art for suctioning waste products from production machines. For example, suction pipes are used as suction elements, wherein the position of the pipe can be adjusted manually so that, depending on the application, the waste products occurring on the production machine can be suctioned very efficiently. These pipes lead into a main line in which a negative pressure is generated by means of a blower. Disadvantageously, interfering geometries partially occur in the main line. Furthermore, in known suction...
