Abstract

PURPOSE:To apply liquid substance in arbitrary film thickness by enabling the supporting position of both a bar and a trestle to be arbitrarily changed to the direction vertical to the face on which coating is applied. CONSTITUTION:The shafts for supporting a bar 1 are formed to both ends of the bar 1. The shafts of the bar 1 are perforated in the side faces of a trestle 2 and the long holes capable of vertically moving are provided. The screws capable of regulating height of the bar 1 by pushing the shafts 1 of the bar 1 from the upper parts of the long holes are provided. The shafts of both ends of the bar 1 are fixed at once to a bar fitting base and this bar fitting base is supported so that it can be vertically moved for the trestle 2. Film thickness is regulated by fitting a micrometer to the trestle 2 and moving this to push the shafts into both ends of the bar 1 and regulating height of the bar 1. Thereby arbitrary film thickness can be obtained by coating.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a variable thickness coating bar that can apply a liquid material to an arbitrary thickness.

[Conventional technology]

BACKGROUND ART Conventionally, liquid substances have been applied using a coating bar to protect, modify, color, etc., metal plates, glass plates, flexible films, etc. The following coating bars were available: 1. A wire bar made by wrapping stainless steel wire around a stainless steel rod so that there are no gaps. 2. Applicator bar with both ends of the bar fixed to the stand. 3. A one-car type applicator bar assembly in which a bar with an eccentric circular cross section is rotatably supported on a pedestal.

[Problem to be solved by the invention]

However, when changing the coating thickness, it is necessary to prepare wire bars with stainless steel wires of different diameters, and applicator bars with multiple bars with different distances between the bar and the surface of the object to be coated. It was uneconomical and there were no delicate intervals. In addition, in the Baker type applicator bar, the mechanism is to adjust the gap between the surface of the object to be coated and the eccentric bar by rotating an eccentric bar to change the coating thickness. The bar was difficult and expensive to manufacture. In addition, for products that require delicate film thickness adjustment or when increasing the film thickness setting, it is necessary to increase the diameter of the eccentric bar.
As the entire bar became larger, the weight also increased, causing poor handling. Therefore, an object of the present invention is to eliminate these drawbacks and provide a variable thickness coating bar that can coat a liquid material with an arbitrary thickness. [i1! Means for Solving the Problem] In order to achieve the above object, the present invention is configured as follows. In other words, the variable thickness coating bar of the present invention is a coating bar consisting of a bar and a pedestal that supports both ends of the bar, and the supporting position of the bar and pedestal can be arbitrarily set in the direction perpendicular to the surface to be coated. It is configured so that it can be changed to The present invention will be explained in more detail with reference to the drawings. FIG. 1a is a front view showing the coating bar of the present invention;
b is a side view. 1 indicates a bar, and 2 indicates a pedestal. The bar 1 has a shape having a tangent line necessary for smooth coating, that is, a columnar or prismatic bar. Moreover, if the tangent line is step-like, it is possible to coat the coating film with several thicknesses with -degree coating. Furthermore, the temperature of the bar 1 can be controlled by making the bar 1 hollow and passing liquid or gas at a certain temperature inside the bar 1. The pedestals 2 are attached to both ends of the bar 1 to maintain a constant distance between the bar 1 and the object to be coated. Therefore, the lower surface of the pedestal 2 has a mirror finish. Also,
The supporting positions of the frame 2 and the bar 1 are configured to be movable arbitrarily in a direction perpendicular to the surface to be coated so that the coating thickness can be freely changed. Specifically, the following aspects are possible. 1. Shafts for supporting the bar 1 are formed at both ends of the bar 1. The pedestal 2 has a long side surface that allows the shaft of the bar 1 to pass therethrough and is movable up and down. A screw is provided that can adjust the height of the bar 1 by pushing the shaft of the bar 1 from the long top. Further, a spring for pushing up the bar 1 is provided at the bottom of the elongated portion. In other words, the axis of bar 1 is
Its position is determined by a screw from the top and a spring from the bottom. 2. Once the shafts at both ends of bar 1 are fixed to the bar mounting base,
This bar mount is supported so as to be movable up and down relative to the pedestal 2. Further, as a mechanism for adjusting the coating film thickness to a desired thickness, there are the following mechanisms. 1. Adjust the height of the bar 1 by attaching a micrometer to the micrometer mount 2 and moving it to push in the shafts at both ends of the bar 1 (see Figure 3). 2. Attach a dial gauge to the dial gauge stand 2, move it, and push in the shafts at both ends of the bar 1 to adjust the height of the bar 1 (see Figure 4). 3.1IIIJl-Adjustment stand Separately from the coating bar, a film thickness adjustment stand is used. In the film thickness adjustment table, a sensor 10 protrudes from the lower surface of a smooth table 9. Place the coating bar on the table 9 of this film thickness adjustment table, put the bar 1 against the sensor 10, and
(See Figure 5). The configuration 3 above is particularly preferable when it is necessary to frequently wash the coating liquid adhering to the coating bar because the coating bar can have a simple structure.

【Example】

Actual thickness variable coating bar is made of stainless steel frame 2.
and a stainless steel bar 1 which has a perfect circular cross section and whose both ends are processed into a rectangular cross-sectional shape to serve as attachment parts to the pedestal 2. Insert the mounting parts at both ends of the bar 1 into the pedestal 2, insert the spring 3 into the gap between the mounting part of the bar 1 and the pedestal 2, insert the screw 4 from the outside of the pedestal on the opposite side of the spring position, and then 3
By sandwiching and fixing the mounting portion of the bar 1, a variable thickness coating bar was constructed (see Fig. 1). A pedestal 2, a bar mount 7, and a bar 1 were prepared, both ends of the bar 1 were passed through the mount 2, and the tip of the bar 1 was fixed to the bar mount 7 with a bar fixing screw 8. The gap between the pedestal 2 and the bar mount 7 was adjusted using the bar position fine adjustment screw 5, and the pedestal 2 and the bar mount 7 were fixed using the bar mount fixing screw 6 to form a variable thickness coating bar. (See Figure 2). Effects of the Invention 1 The variable thickness coating bar of the present invention is a coating bar consisting of a bar and a pedestal that supports both ends of the bar. Since it is configured so that the thickness can be changed arbitrarily, coating can be performed to any desired thickness using a variable thickness coating bar. Furthermore, since the structure is very simple, it is easy to manufacture a variable thickness coating bar.
