Description

BOPA production line water bath roller

Technical Field

The utility model relates to an improvement invention of BOPA production equipment, in particular to an improvement invention of a water bath roller of a BOPA production line.

Background

BOPA is an english abbreviation of Biaxially oriented polyamide (nylon) film, which is an important material for producing various composite packaging materials. The in-process that current BOPA production line water bath roller conveyed the film, the conveying synchronism is poor between the roller, and has water to exist between roller surface and the film, and unable quick drainage all leads to producing relative slip between film and the roller, and the fold takes place for the film and damages.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome prior art not enough, provide a reliable and stable BOPA production line water bath roller of film conveying.

In order to solve the technical problem, the utility model discloses an adopt following technical scheme to realize: this kind of BOPA production line water bath roller, including a plurality of rollers, its characterized in that: the roller comprises a roller body and a roller shaft, wherein the roller shaft is arranged at each of two ends of the roller body respectively, the roller shaft is connected with an end port of the roller body through a flange sealing structure, the surface of the roller body is coated with a nitrile rubber layer, and the hardness of the nitrile rubber layer is 70-75 Shore; the surface of the nitrile rubber layer is provided with grid lines, and the depth of grooves of the grid lines is 2 mm; the rollers are connected through flat belts and are driven by a motor.

The flange sealing structure comprises a first flange plate and a second flange plate which are fixedly connected, a sealing gasket is arranged between the first flange plate and the second flange plate, the first flange plate is welded on one side of the roller, and the second flange plate is welded on one end of the roller shaft.

The rollers are provided with three or four rollers.

The utility model has the advantages that the improved BOPA production line water bath roller has the advantages that the surface of the roller is coated with rubber and is provided with grid lines, thereby playing the roles of stretching the film and quickly draining water and reducing the wrinkles of the film; the driving motor is shared, the rollers are driven by a flat belt, so that the relative sliding between the film and the rollers is reduced, and the scratch problem of the film is reduced.

Drawings

The following describes the present invention in further detail with reference to the accompanying drawings.

Figure 1 is the structure section view of the utility model discloses a roller.

Figure 2 is the utility model discloses a plurality of roller transmission sketch map.

Detailed Description

The drawings show the structure of the present invention, and the details thereof will be further described with reference to the drawings. The BOPA production line water bath roller comprises a plurality of rollers 1, preferably three or four rollers 1 are arranged, each roller 1 comprises a roller body 11 and a roller shaft 12, the roller shafts 12 are arranged at two ends of each roller 1 respectively, the roller shafts 12 are connected with ports of the rollers 1 through flange sealing structures 2, the surfaces of the roller bodies 11 are coated with nitrile rubber layers 3, the hardness of the nitrile rubber is 70-75 Shore degrees, and appropriate softness and friction force are guaranteed; the surface of the nitrile rubber layer 3 is provided with the grid grains 4, and the depth of grooves of the grid grains 4 is 2mm, so that quick drainage is realized, and wrinkling of a film is avoided; a plurality of rollers 1 are connected through a flat belt 6 and driven by a motor 5, so that the transmission synchronism is ensured, the film is more stably and reliably conveyed, and the film is prevented from sliding relative to the rollers 1 and damaging the film.

The flange sealing structure 2 comprises a first flange plate 21 and a second flange plate 22 which are fixedly connected through a fastener, a sealing gasket 23 is arranged between the first flange plate 21 and the second flange plate 22, the first flange plate 21 is welded on one side of the roller 1, the second flange plate 22 is welded on one end of the roller shaft 12, and the flange sealing structure 2 is convenient to install and reliable in sealing.

In summary, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
