Abstract
Description
Technical Field:The invention relates to the field of clean room technology, in particular to a cover for paper cores of adhesive rolls, which cover is equipped with a thread mechanism in order to prevent the release of particles in clean room.Prior Art:Adhesive rollers with paper cores are frequently used in clean rooms, but represent a potential source of particle contamination. Existing solutions such as plastic covers for paper cores do not provide a simple mechanism for securely and firmly securing the cover to the paper core. In addition, the existing attachment solutions are often complex or time consuming.Object of the invention:The object of the invention is to provide a cover which prevents particle release and is easy to install and is securely fixed to the paper core. A user-friendly fastening mechanism is to be integrated, which enables rapid and simple assembly.DESCRIPTION OF THE INVENTIONThe invention relates to a cover for paper cores of adhesive rolls, which cover has a special fastening mechanism in the form of an internal thread. This thread is designed such that it can be securely screwed onto the paper core and tightened with only one rotation. This allows rapid assembly and disassembly of the cover, which significantly simplifies handling in clean rooms.The thread is located in the inner region of the cover and is designed so that it corresponds exactly to the outer surface of the paper core. After the cover has been attached to the core, a single rotation produces a firm connection which prevents unintentional detachment of the cover.The cover itself consists of an antistatic, low-particle material which is suitable for use in clean rooms. This material does not release any particles and is resistant to chemical influences which can occur in clean rooms. The mechanism also allows repeated use of the cover without wear or damage to the adhesive rollers.Advantages of the Invention:• Efficient assembly: The dedicated thread mechanism allows the cover to be fastened quickly and with only one rotation, which accelerates the work in the clean room.• Secure fixation: The cover remains firmly seated on the paper core, so that no particles are released.• Clean room capability: The material used meets clean room standards and prevents particle release or chemical contaminants.• Re-operability: The cover can be used several times without losing functionality, making it particularly economical and durable.Application Area:The invention is ideal for use in clean rooms in the semiconductor industry, the pharmaceutical industry and in other industries in which high particle cleanliness is required.
Claims
Claim 1: Cover for paper cores of adhesive rolls (Fig. 3), characterized in that it is produced by means of 3D printing. The material is PLA or another filament suitable for 3D printing. The cover has a thread-like fixing structure (1). This makes it possible to screw the cover firmly onto the paper core with a rotation. The paper core is completely encapsulated to protect it from particle contamination (3).Claim 2: Cover according to claim 1, characterized in that the thread-like form (1) is manufactured precisely by the 3D printing method in order to ensure a precisely fitting and firm fixing on the paper core without impairing the functionality of the adhesive roller.Claim 3: Cover according to claim 1 or 2, characterized in that the material made of PLA or another 3D-printable filament is suitable for use in clean rooms, since it is very low in outgassing and thus minimizes the risk of contamination due to chemical outgassing.Claim 4: Cover according to any one of the preceding claims, characterized in that it comprises a thread-like guiding aid which facilitates the first engagement of the thread-like structures and assists the rapid, secure holding of the cover on the paper core.Claim 5 : Cover according to any one of the preceding claims, characterised in that it has a recess (2) or a structured surface which facilitates the gripping and tightening of the cover in order to ensure easy handling during screwing and screwing.
