Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides pressure rolls 2 at the front and rear of the application roll 1, separated from each other to the extent that the primer adhering to the surface of the application roll 1 does not adhere to the surface of the application roll 1.
, 3 are provided, and the pressure roll 2 is lower than the application surface 4 of the application roll 1.
, 3 are positioned above, and an upper auxiliary pinch roll 12 is provided between the coating roll and the rear sho roll 2 to prevent the material to be coated 9 from colliding with the coating roll 1.
A material to be coated 9 is placed between the applicator roll 1 and the front pressure roll 3.
The present invention relates to a paint coating device characterized in that it is equipped with a lower auxiliary pinch roll 13 that prevents the material from falling and guides it to the bottom roll 3. To provide a paint coating device in which the brusher of the coating roll does not adhere to the pressure roll and is not transferred onto the material to be coated by the pressure roll to stain the surface.

As shown in FIGS. 2 and 3, the conventional paint applicator has a pressure roll 8 disposed directly below the application roll 7, so when the material 9 to be coated is thin, the application roll 7 and pressure roll The gap with the roll 8 becomes very small. Therefore, after coating one material to be coated and before coating the next material to be coated, the primer adhering to the application roll 7 will adhere to the pressure roll 8, and the primer adhering to the pressure roll 8 will be transferred to the material to be coated. This has the disadvantage that it stains the surface by being transferred onto the surface of the paint, and it has been practically impossible to coat the material by roll coating if the material to be coated is thin. The present invention was invented in view of the above-mentioned disadvantages, and will be explained in detail below with reference to Examples.

In the figure, reference numeral 1 denotes a coating roll, and pressure rolls 2 and 3 are placed in front and behind the coating roll 1 at a distance such that the primer adhering to the surface of the coating roll 1 does not adhere. Here, the tops 5 and 6 of the pressure rolls 2 and 3 correspond to the coating surface 4 of the applicator roll 1.
It is located above the material to be coated 9.
is pressed downward by the coating roll 1 between the pressure rolls 2 and 3 to perform coating. A pinch roll 10 is arranged behind a pressure roll 2 arranged behind the application roll 1 with respect to the traveling direction of the material 9 to be coated. It is located below the top 5 of the roller 2, and has the effect of pushing up the material 9 to be coated in front of the pressure roll 2, ensuring that the material 9 to be coated reaches the pressure roll 3 in front of it. Primer is now applied. In the figure, reference numeral 12 denotes an upper auxiliary pinch roll, which is installed just before the coating roll 1 because the tip of the material 9 to be coated pushed up by the pressure roll 2 at the rear scratches the surface of the coating roll 1. It plays the role of turning material 9 slightly downward. Reference numeral 13 is a lower auxiliary pinch roll, which moves the tip of the material to be coated 9 downward and connects it to the front roll 3.
It is provided to prevent the tip of the material 9 to be coated from falling to the lower side of the pressure roll 3 in front after coating. In the figure, 14 is a primer tank, 1
5 and 16 are transfer rolls. The material to be coated used in the present invention includes elastic synthetic resins, metals, wood, and various other materials. In the present invention, as described above, pressure rolls are provided before and after the application roll at a distance such that the primer adhering to the surface of the application roll does not adhere.
Since the top of the pressure roll is positioned above the application surface of the application roll, it is possible to prevent the primer adhering to the application roll from adhering to the base roll and from adhering the primer to unnecessary surfaces of the material to be coated. This has the advantage that unnecessary surfaces are not contaminated, and even if the material to be coated is thin, it is not only coated reliably by the coating roll, but also the primer does not adhere to unnecessary areas. Furthermore, the upper auxiliary pinch roll provided between the applicator roll and the rear pressure roll can push down the material to be coated and prevent the tip of the material to be coated from colliding with the applicator roll and damaging the applicator roll. There is an advantage. Another advantage is that the lower auxiliary pinch roll provided between the applicator roll and the pressure roll in front allows the tip of the material to be coated to be reliably guided to the pressure roll while preventing the material to be coated from falling. There is.

Claims (1)

[Claims] 1 Pressure rolls are installed before and after the applicator roll so that the primer adhering to the surface of the applicator roll does not adhere, and the top of the press roll is positioned above the coating surface of the applicator roll, and the applicator roll and the rear pressure roll are separated. An upper auxiliary pinch roll is installed between the applicator roll and the front pressure roll to prevent the material to be coated from colliding with the coating roll, and a lower pinch roll is provided to prevent the material to be coated from falling between the coating roll and the pressure roll in front of the coating roll and guide it to the pressure roll. A paint application device characterized by being provided with an auxiliary pinch roll.
