Description

[Detailed description of the invention] [Field of industrial application] The present invention is a coating plate for an extrusion coating tube, and more specifically, an extrusion coating tube for simultaneously forming a large number of coated surfaces in a striped pattern on a surface of a constant width. This relates to a coating plate that is removably attached to the.

[Conventional technology]

Conventionally, pastes, adhesives,
Examples of methods that apply chemicals, etc. in multiple rows with a constant width at regular intervals include the method shown in Japanese Patent Publication No. 56-42340, and the method shown in Figs. 1 and 2 in the longitudinal direction of a cylinder. There is a method using an extruded coating tube with a coating liquid outflow slit of a certain width and depth.

[The problem that the idea aims to solve]

These are called partition plates or forming plates for the coating liquid.If there are two rows of coating layers, one flow divider plate is used, and if there are three rows, two flow divider plates are used. , by inserting the required number of sheets into the flow path of the coating liquid according to the number of rows of coating layers,
Furthermore, the width of the coating layer has been controlled by adjusting the spacing between flow divider plates. These things are different if it is enough to just form multiple rows of coating layers all over the base material, but it is required that multiple rows of coating layers of a certain width be applied at regular intervals. In cases where dimensional accuracy is required, mounting the flow divider plate becomes an extremely difficult task.
This is shown in Figures 1 and 2. After inserting the flow divider plate 3 into the slit 2, in order to fix the flow divider plate 3 to the tube 1, the flow divider plate is tightened with bolts 4 from both sides. However, the position of the flow divider plate 3 is likely to move during this tightening, and it is extremely difficult to fit a large number of flow divider plates 3 of a certain size into the slit 2 at a fixed position.

In addition, during use of the coating tube 1 that is inserted and attached in this way, the flow divider plate 3 may move, and the flow divider plate 3 may be deformed over time, resulting in the occurrence of defective products. It was found that the system also has the disadvantage of requiring constant monitoring.

In view of these points, the present invention not only allows for the formation of multiple rows of coating layers of a constant width at regular intervals on a base material in place of the flow divider plate, but also facilitates attachment and detachment operations to the extrusion coating tube. The purpose of the present invention is to provide a coating plate for an extrusion coating tube that is easy to coat, does not cause any variation in coating width or coating amount even during coating work, and allows the coating amount to be adjusted as necessary. It has been done.

[Means to solve the problem]

In order to achieve the above-mentioned purpose, the inventors of the present invention have proposed that a cylindrical extruded coating tube is removably attached to a coating solution outflow slit provided in the length direction of the extruded coating tube, and when attached to the extruded coating tube, the coating solution is removed. This objective can be well achieved by providing a coating plate for an extrusion coating tube that has two or more coating liquid outflow spaces spaced at desired intervals to form a coating liquid flow path between the surface of the liquid outflow slit and the surface of the liquid outflow slit. The present invention was obtained.

[Effect]

When the coating plate of this invention is attached to the slit, it only needs to be attached once, which allows the coating plate to be regulated by the width of the coating layer and the spacing between the coating layers. , multiple rows of coating layers with a predetermined width and a predetermined interval are formed on the base material in an orderly manner, and the difficult work of fixing each flow divider plate in a predetermined position as in the conventional method is eliminated. It became a thing.

〔Example〕

An example of the implementation of the present invention will now be described with reference to the accompanying drawings. First, the one shown in FIGS. 1 and 2 is a conventional one in which a flow dividing plate 3 is inserted into a slit 2 of an extruded coating tube 1 and fixed by tightening bolts 4 from both sides. As mentioned above, there is a drawback that mounting the flow dividing plate 3 is an extremely difficult task. Figure 3 and the following show an example of the implementation of the present invention, in which 1 is an extruded coating tube;
Reference numeral 2 denotes a slit in the extrusion coating tube 1, and this slit 2 is a coating liquid outflow slit. The coating liquid is stored in the cylindrical cavity 5 of the coating tube 1, and is pumped into this via a pipe from a separately provided coating liquid tank. Reference numeral 6 denotes a coating plate which has a thickness approximately the same as the gap between the slits 2 of the extruded coating tube 1, and is inserted into the slits 2 and fixed by tightening with screws 4, for example. A coating liquid outflow space 7 is formed in this coating plate 6 . This coating liquid outflow space 7 also serves as a coating liquid flow path. 1 of this coating liquid outflow space 7
One form, as shown in FIG. 5, is to form the coating plate 6 in the shape of a comb, and use the cutout portion as the coating liquid outflow space 7. In this case, on both sides of the coating plate 6, The slit surface of the extruded coating tube 1 forms a coating liquid outflow passage. Another form of the coating liquid outflow space is as shown in FIG. When a surface of a certain coating plate 6 and one surface of a slit in the extrusion coating tube 1 match, a coating liquid outflow passage is formed.

The coating liquid outflow space 7 has a length 8 of the coating width of the coating liquid and a depth 10 which is deeper than the depth 9 of the slit 2. That is, the coating width of the coating liquid is set to a length that forms the coating liquid outflow space, and the depth that is deeper than the depth of the slit is set to the depth that forms the coating liquid outflow space. The protruding pieces 11 formed on both sides of the coating liquid outflow space in this coating plate also act as pieces that prevent the coating liquid from flowing out, so the upper ends of the many protruding pieces 11 formed on the coating plate are on the same straight line. It is desirable that the In order to attach this coating plate 6 to the slit 2, it is usually necessary to attach it horizontally so that the upper end of the protruding piece 11, which is the end surface of the coating plate 6, and the upper end of the slit are on the same plane. good.

As the material for this coating plate 6, metal, glass fiber reinforced synthetic resin, silicon resin, etc. are preferably used.

[Effect of idea]

Since the present invention is constructed as explained in detail above, it is possible to obtain extremely high dimensional accuracy of the coating liquid outflow space of the coating plate, and this is extruded and inserted into the slit of the coating tube. Because it is relatively simple and easy to apply with high precision, and can be installed in one operation, it is possible to simultaneously obtain a large number of coated surfaces with a fixed width and a fixed spacing, and the coating plate can be coated easily. Since the position does not change during work, there is no change in coating width or coating amount, and it is possible to adjust the coating amount as necessary, allowing for multiple coatings on a fixed width surface. This invention is noteworthy from a practical point of view, as it makes it easy to simultaneously form a striped surface and significantly contributes to improved efficiency and coating accuracy.
