Abstract
Aluminium foil nip roll, it is same to solve the problem that exists among the prior art, and this nip roll's structure is: the roller becomes cylindrical, and there is the spindle nose at both ends, on the face of cylinder of roller, by the axis center beginning of roller, processes left -hand screw groove and the right spiral groove that has two symmetries to both ends respectively, and the pitch of two spiral grooves is 6 -9mm, and the lines width is 0.3 -0.6mm. Adopting this technical scheme, before the aluminium foil gets into the complex, letting the aluminium foil walk around more than one aluminium foil nip roll, nip roll is last to be exerted oneself aluminum foil film to expand to both ends by the centre by the outside spiral groove that expandes in centre, and the pincher trees exhibition on the messenger aluminum foil film is flat. Advancing and testing many times, the pitch of two spiral grooves is at 6 -9mm, when the lines width is 0.3 -0.6mm, and the effect that pincher trees launched is best.
Description
Technical field
This technology belongs to aluminium-foil paper and produces equipment technical field, relates to a kind of aluminium foil nip rolls.
Background technology
In the production process of aluminium-foil paper, aluminium foil wants lining paper to carry out viscose glue compound, and before viscose glue compound, aluminium foil is attached on one layer of plastic foil, will peel off and transfer on coil paper band from plastic foil.It is attached with the plastic foil of aluminium foil from unreeling transfer, will on multiple deflector rolls of compounding machine around the movement, in motor process, affected by factors such as the disturbance of plant equipment, air flowing, frictional statics, aluminium foil film there will be tiny wrinkle, these aluminium foils with wrinkle are once being compound on paper tape, and what produce is exactly underproof aluminium-foil paper product.At present, prevent aluminium foil film from directly wrinkling the main method adopting and extending before composite roll aluminium foil film length as far as possible and tightened by film from middle part, allow aluminium foil flatten, but due to the limited space of length between prolongation roller on compounding machine, tightening the limited strength of film, on aluminium foil, some wrinkle still can not be flattened.
Summary of the invention
For in prior art, in process of production, the wrinkle occurred are difficult to the problem of all flattenings to aluminium-foil paper, and this utility model provides a kind of aluminium foil nip rolls, solve problems of the prior art, the structure of this aluminium foil nip rolls is: roller becomes cylinder, and there is spindle nose at two ends, on the face of cylinder of roller, by the axis centre of roller, having two symmetrical left-hand screw concaves and right-hand screw concave to two ends processing respectively, the pitch of two spiral concaves is 6-9mm, and line thickness is 0.3-0.6mm.
Adopt the technical program, before aluminium foil enters compound, allow aluminium foil walk around more than one aluminium foil nip rolls, aluminium foil film is firmly launched to two ends by centre by middle flared spiral concave by nip rolls, makes the wrinkle on aluminium foil film flatten.Entering many experiments, the pitch of two spiral concaves is when 6-9mm, line thickness are 0.3-0.6mm, and the effect that wrinkle launch is best.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment, as shown in Figure 1: a kind of aluminium foil nip rolls, 2 one-tenth of roller is cylindrical, there is spindle nose 1 at two ends, on the face of cylinder of roller 2, by the axis centre of roller, having two symmetrical left-hand screw lines 3 and right-hand helix 4 to two ends processing respectively, the pitch of two helixes is 8mm, and line thickness is 0.5mm.
