It has been made easier to replace and clean.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a contactless, floating dryer, that is, a floating dryer used for coating, impregnating, or laminating a web material such as paper, cloth, plastic film, metal foil, or non-woven fabric.

[0002]

[Prior art]

 Floating dryers are used by fixing horizontally because they are easy to adapt to various coating liquids with different fluidity. Generally, heated air is used as a drying medium, and it is preferable to install vertically in terms of operating efficiency such as thermal efficiency.However, in the vertical type, the coating liquid easily drips, and the smoothness of the dried film, and thus the uniform film thickness. It is easy to lose the property. Therefore, it is difficult to apply it to a wide variety of coating liquids, uses, and conditions, and most of the time, it is installed horizontally and used.

[0003]

[Problems to be solved by the device]

 This plan will improve energy efficiency by eliminating such restrictions, and will meet the wide-ranging requirements of the increasingly sophisticated and diversified processing industry.

[0004]

[Means for solving the problem]

 By making the dryer main body, that is, the dryer box movable, and changing the web running direction, that is, the dryer box from horizontal to vertical freely and continuously even during operation, without impairing the coating finish state, In addition, the angle can be adjusted and set so that the energy efficiency is better.

In addition, for easy and easy disassembly / cleaning and replacement of parts, a bolt nut that is easy to remove and a plug-in hinge are used. I assembled it.

That is, the fulcrum pin by driving the motor shown in FIG. 1 is moved up and down via the rack and pinion mechanism, and the angle of the dryer box is changed as shown by the dotted line. Fig. 2 shows the basic structure of the floating dryer of the present invention. The nozzle box of is designed to be inserted into the duct box of, and is fixed by bolts. The medium heated outside is connected to the duct box, and the heating medium filled in the duct box also fills the nozzle box and blows out from the nozzle hole to float the material (11). Exhaust gas containing solvent vapor fills the gap between the duct box and the outer wall of the dryer box, passes through and is discharged to the outside.

As shown in FIG. 3, the heating medium blowing nozzles facing each other insert a three-point movable hinge into an insertion port fixed to the duct box, and adjust the movable fulcrum of the hinge to adjust the interval. Fix both boxes in parallel with the right bolt nut (10) in the figure at the same interval as the left side.

[0008]

[Action]

 The dryer angle can be continuously raised from the horizontal to the vertical by a motor drive and can be stopped at any desired angle.Adjust the angle according to the viscosity and fluidity of the coating agent, the volatility of the solvent, the coating thickness, etc. The drying efficiency can be increased. In addition, various conditions such as drying temperature, medium flow rate, roll difficulty angle of the web material coating portion, and incident angle to the winding portion can be widely selected and adjusted to suit the material conditions.

【effect】

 There are usually two types of dryers, a vertical type and a horizontal type. The vertical type has good thermal efficiency, but it has the drawback that the coating liquid tends to drip because the coated object is vertical. In the horizontal type, the coated object is horizontal, so that the coating solution does not drip and a dry film with good smoothness can be obtained, but the energy efficiency is not as good as in the vertical type.

The movable type of the present invention can raise the thermal efficiency while suppressing the defects of the vertical type by raising the dryer and slanting it in a range that does not cause dripping according to the fluidity of the coating liquid. By simply adjusting the angle of the dryer, you can improve the drying efficiency and save energy without affecting the performance of the membrane.

It is possible to give thixotropic properties to the coating liquid so that it does not sag even when it is vertical, but it requires very complicated liquid adjustments such as composition and formulation, and the flow of the liquid does not affect the performance of the film. It is actually very difficult to control only the sex, and the current situation is to avoid the problem of sagging by using a horizontal dryer. That is, a horizontal horizontal type is often used as a dryer that can be used for various coating liquids, giving up on improving thermal efficiency. The vertical type is used for so-called special cases, which can be applied only in special cases where there is no sagging problem.

The present invention is very useful in the sense that it provides a general-purpose dryer that solves all of these problems at once, and its effect is extremely large. Especially when transferring from the R & D stage to actual production, it is not enough to simply dry well in actual production. Although optimum setting and control are required, it can be said that the movable floating dryer according to the present invention has increased the number of weapons that satisfy this condition.
