Description

Novel antiseized guide roll device

Technical Field

The utility model relates to a novel anti-sticking guide roller device, and belongs to the field of adhesive tape coating equipment.

Background

At present, guide rollers arranged on adhesive tape coating equipment are smooth aluminum rollers or hard chromium plated steel rollers, and in the production feeding process, as a coating layer is arranged on the surface of a material film, when the coating layer is contacted with a roller body, the roller body and the material film are adhered, so that the quality problems of uneven feeding, stripping scratch of the coating, breakage of the coating and the like can be caused, and the production quality requirement can not be met.

Disclosure of Invention

Aiming at the problems in the prior art, the utility model provides a novel anti-sticking guide roller device, so as to solve the technical problems.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: a novel anti-sticking guide roller device comprises a guide roller arranged on adhesive tape coating equipment; the guide roller is provided with a knurling layer; the knurling layer is composed of a plurality of knurling blocks, and the knurling blocks are uniformly distributed.

Further, the knurling block is of a square cone structure with a bulge in the middle and inclined and downward surrounding surfaces.

Further, the cone height of the knurling block is 0.73mm, and the side length of the square bottom surface is 1.5mm.

Further, the two surfaces contacted by the two adjacent knurling blocks are perpendicular to 90 degrees, and a gap formed by two perpendicular surfaces is reserved between the knurling blocks and the material film.

Further, the surface of the guide roller is coated with a teflon layer.

The beneficial effects of the utility model are as follows: according to the technical scheme, knurling and Teflon coating processes are adopted on the surface of the guide roller, so that the contact area and the air suspension effect can be effectively reduced in the process of contact between the material film and the roller body, the flatness of the material film is ensured, and the phenomena of adhesion, scratch, tearing and the like of the material film are avoided.

Detailed Description

The present utility model will be further described in detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the detailed description and specific examples, while indicating the utility model, are intended for purposes of illustration only and are not intended to limit the scope of the utility model.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs, and the terms used herein in this description of the utility model are for the purpose of describing particular embodiments only and are not intended to be limiting of the utility model.

As shown in fig. 1, 2 and 3, a novel anti-sticking guide roller device comprises a guide roller 1 arranged on adhesive tape coating equipment; the guide roller 1 is provided with a knurled layer 11; the knurled layer 11 is composed of a plurality of knurled blocks 111, which are uniformly arranged.

In this embodiment, the knurling block 111 is preferably a square cone structure with a protrusion in the middle and inclined downward on the peripheral surface.

In this embodiment, the height of the cone of the knurling block 111 is preferably 0.73mm, and the side length of the square bottom surface is 1.5mm.

In this embodiment, preferably, the two surfaces contacted by two adjacent knurling blocks 111 are perpendicular 90 degrees, and a gap formed by two perpendicular surfaces is left between the knurling blocks 111 and the material film.

In this embodiment, the surface of the guide roll 1 is preferably coated with a teflon layer.

Through analysis after verification for many times, the glued material film is dried and cooled and shaped by an oven, but the surface has slight viscosity, and the material film and the roller body have certain wrap angle and material feeding structure requirements, so that bonding with different degrees can occur, and the phenomena of uneven material film, scratch of a coating layer and tearing of the material film can be caused; according to the diameter of the guide roller, different knurling depths and sizes are calculated according to the diameter of the guide roller and the wrap angle, see particularly fig. 2 and 3, because the too deep mesh pits can lead to bump breaking and breaking of the material film, the too shallow mesh pits can not form a suspended air layer, the anti-sticking effect can not be achieved, a large number of experiments are carried out through the different knurling depths, the most suitable mesh pits are determined, and the feeding problems of leveling, non-adhesive tearing, breakage, scratch and the like are achieved.

According to the technical scheme, knurling and Teflon coating processes are adopted on the surface of the guide roller, so that the contact area and the air suspension effect can be effectively reduced in the process of contact between the material film and the roller body, the flatness of the material film is ensured, and the phenomena of adhesion, scratch, tearing and the like of the material film are avoided.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, or alternatives falling within the spirit and principles of the utility model.
