Description

Technical Field

[0001] The utility model belongs to the technical field of color-coated plate coils, in particular to a continuous coating tool for color-coated plate coils. Background Art

[0002] The coating tooling of color-coated coils refers to various equipment and tools used in the production process to evenly apply the paint on the metal coil to form a layer of coating with protective and decorative effects. The production process of color-coated coils usually includes: unwinding, cleaning, painting, curing and winding.

[0003] The cleaning steps of existing color-coated coil coating tooling are relatively cumbersome when replacing the washing liquid, and in some cases the machine needs to be stopped, which reduces production efficiency. Utility Model Content

[0004] The utility model aims to provide a continuous coating tool for color-coated plate coils, which can continuously clean the color-coated plate coils by replacing the washing liquid when cleaning the color-coated plate coils without stopping the work.

[0005] The color-coated sheet coil continuous coating tool comprises a vertically arranged box for cleaning the color-coated sheet coil, wherein a nozzle assembly and a cleaning assembly that can move left and right are arranged in sequence from left to right in the box, and two guide pipes for water inlet are connected to the nozzle assembly, and a collecting tank is arranged in the box below the nozzle assembly and the cleaning assembly, and a cleaning area for the color-coated sheet coil to pass horizontally is formed between the nozzle assembly and the collecting tank;

[0006] A circulation pipe is installed at the bottom of the collection tank, one end of the circulation pipe is connected to the collection tank, and the other end is connected to the water tank. A first solenoid valve is installed on the circulation pipe;

[0007] There are two chambers in the water tank, one of which is connected to the circulation pipe, one end of two guide pipes is connected to the two chambers respectively, and the other end is connected to the nozzle assembly;

[0008] A waste water pipe is installed at the bottom of the collecting tank on one side of the circulation pipe, and a second solenoid valve is installed on the waste water pipe. The water outlet speed of the waste water pipe is at least five times that of the water outlet speed of the nozzle assembly.

[0009] When there is no need to replace the washing liquid, the washing liquid in the collecting tank enters the water tank through the circulation pipe, and then the water flowing into the water tank through the circulation pipe is supplied to the nozzle assembly through the corresponding guide pipe, and the nozzle assembly sprays to the color-coated plate coil in the cleaning area for cleaning; when the washing liquid needs to be replaced, the first solenoid valve on the circulation pipe closes the circulation pipe, and the second solenoid valve opens the waste water pipe to discharge the waste water in the collecting tank. After the washing liquid in the corresponding chamber flowing into the circulation pipe in the water tank is used up, the nozzle assembly is supplied with water through the clean washing liquid in another chamber in the water tank. The water outlet speed of the waste water pipe is at least five times that of the water outlet speed of the nozzle assembly. After the water in the collecting tank flows out, the second solenoid valve is closed, the waste water pipe is closed, the first solenoid valve is opened, the circulation pipe is opened, and the clean washing liquid is sufficient. After that, stop supplying new washing liquid, and then switch to the washing liquid flowing into the water tank through the circulation pipe to supply liquid to the nozzle assembly, thereby achieving continuous cleaning of the color-coated plate coil when the washing liquid is replaced, without stopping work, thereby solving the problem of cumbersome washing liquid updating operation.

[0010] Furthermore, a baffle which can open and close the interior of the collecting tank is hinged in the collecting tank.

[0011] The baffle is located in the area below the slot. When the nozzle assembly sprays the replaced washing liquid, the baffle closes the upper area of ​​the collecting tank. After the waste washing liquid is discharged through the waste water pipe, the baffle is swung, and the washing liquid in the collecting tank above the baffle enters the bottom of the collecting tank, thereby preventing the new washing liquid from being wasted.

[0012] Furthermore, guide rails are installed in the box body so that both the nozzle assembly and the cleaning assembly can slide left and right.

[0013] The left and right sliding of the nozzle assembly and the cleaning assembly are achieved by sliding blocks respectively fixed on the nozzle assembly and the cleaning assembly and slidably matched with the guide rail, so as to facilitate cleaning.

[0014] Furthermore, feed shafts for guiding the color-coated sheet coils are installed on the left and right outer walls of the box body, and corresponding feed shafts are provided with openings communicating with the inside and outside on the box body, the opening on the left is the feed opening, and the opening on the right is the discharge opening.

[0015] The feeding shaft guides the color-coated sheet coil, making it easy to clean the nozzle assembly and the cleaning assembly.

[0016] Furthermore, the nozzle assembly includes a plurality of nozzles for uniformly spraying the cleaning liquid on the color-coated sheet coil in the cleaning area.

[0017] The number and distribution of nozzles are determined according to the front and rear width of the color-coated sheet coil in the cleaning area, the spraying range and spraying amount of the nozzles.

[0018] Furthermore, the cleaning component is a detachable sponge for cleaning the upper and lower surfaces of the color-coated sheet coil.

[0019] The detachable sponge is composed of two groups symmetrically arranged up and down as a cleaning component. The number of cleaning components is determined according to the cleanliness of the color-coated sheet coil. If it is dirty, multiple groups can be arranged side by side for multiple cleanings.

[0020] Furthermore, a brush for cleaning the color-coated sheet coil at the feed inlet is installed on the outer side wall of the box body at the feed inlet.

[0021] The brush can be used for preliminary cleaning of the color-coated sheet coil.

[0022] Furthermore, a fixing plate is provided on the box body, and the brush is installed on the fixing plate.

[0023] The fixing plate facilitates the installation of the brush.

[0024] Furthermore, an ash box is installed on the outer side wall of the box body below the feed inlet.

[0025] The dust after the color-coated sheet coil is cleaned with a brush is collected by a dust box.

[0026] Furthermore, a circulation pump is installed on the circulation pipe to draw the liquid in the collection tank into the water tank.

[0027] Compared with the prior art, the utility model has the following beneficial effects:

[0028] When the washing liquid is replaced, the color-coated plate coil is still continuously cleaned without stopping the operation, thereby solving the problem of complicated operation of washing liquid renewal. BRIEF DESCRIPTION OF THE DRAWINGS

The washing liquid drips into the collecting tank 10, enters the circulation pipe 8, and is recovered to the water tank 15 through the circulation pump 14 until the washing liquid can no longer be circulated.

[0055] When the washing liquid needs to be renewed, the circulation pump 14 and the first solenoid valve 6 are closed first, and the second solenoid valve 7 is opened, so that the old washing liquid is discharged as waste water through the waste water pipe 9. When the old washing liquid in the water tank 15 is consumed, the new washing liquid is connected to the water tank 15 for use, and the baffle blocks the new washing liquid. When the old washing liquid is almost exhausted, the second solenoid valve 7 is closed, the first solenoid valve 6 and the circulation pump 14 are opened, and the baffle is opened to enter the circulation state.
