Description

Liquid level adjusting structure of paint tray of roller coater

Technical Field

The utility model relates to a roller coating machine paint tray liquid level control structure.

Background

When a roll coater applies a medium such as paint to the surface of a strip material through a roll, a paint tray is typically used to supply the medium such as paint to the roll coater strip roll. In order to ensure the stability of the thickness of the coating, the position of the material carrying roller soaked below the liquid level of the paint needs to be relatively fixed, the roller coater needs to frequently replace the coated paint medium, and the position requirements of the material carrying roller and the liquid level can be adjusted when different paint media are coated. After the coating operation is completed, it is often necessary to quickly replace the paint in the paint tray in preparation for the next coating, which requires that the paint remaining in the paint tray be emptied and cleaned as quickly as possible.

The traditional paint tray has two structural forms:

(1) the overflow mouth and the paint tray of paint tray pass through welded mode and connect, and do not have the evacuation mouth, and this kind of structure has following not enough:

1) the liquid level of the paint is not adjustable, and the paint can only be at the same liquid level height when being coated with any paint medium;

2) after the coating work is finished, the residual paint in the paint tray cannot be emptied quickly, the paint is kept still for a long time and is contacted with the paint tray, and the paint is confined on the paint tray, so that the paint tray is difficult to clean;

3) the paint cannot be emptied, and the paint tray can only be detached from the roller coater when the paint is replaced or the material tray is cleaned, so that the working strength is increased, and the paint tray is filled with the paint, so that the detachment difficulty is high;

4) the waste liquid when the paint tray is cleaned cannot be quickly emptied.

(2) The overflow mouth and the paint tray of paint tray pass through welded mode and connect, have the evacuation mouth, and this kind of structure has following not enough:

2) the emptying port is sealed by a plug under the working state of the roller coater, paint at the bottom of the paint tray is confined in the emptying port due to long-time rest, and the plug is difficult to detach during emptying;

3) the evacuation port needs to be independently connected with a pipeline for evacuation, and the pipeline connection is inconvenient.

The utility model provides a technical scheme that above-mentioned problem adopted is: a liquid level adjusting structure of a paint tray of a roller coater comprises a paint tray body, wherein a paint containing cavity is arranged in the paint tray body; the method is characterized in that: the device also comprises a connector, an overflow regulating pipe and a hose; the interface is fixed at the bottom of the paint tray body; the interface is provided with an emptying port which is communicated with the paint containing cavity; the emptying port is provided with an internal thread; the overflow adjusting pipe is provided with external threads, and the external threads of the overflow adjusting pipe are connected with the internal threads of the emptying port, so that the overflow adjusting pipe is arranged on the emptying port of the interface; the pipe orifice at the top of the overflow adjusting pipe is positioned in the paint tray body, and the pipe orifice is communicated with the paint containing cavity and is higher than the top orifice of the emptying port; the hose is connected on the interface, and the hose communicates with overflow regulating pipe and evacuation mouth.

The utility model discloses still include the support, the paint tray body is installed on the support.

The utility model discloses still include the handle, the handle is installed on the paint tray body.

The bottom of paint tray body be provided with the hole, interface welded fastening is in this hole department.

The top drill way of evacuation mouth flush with the bottom that paint holds the chamber.

The utility model discloses be provided with the opening at overflow control tube top.

The opening is cross-shaped.

Compared with the prior art, the utility model, have following advantage and effect:

(1) the liquid level in the paint tray is adjustable, convenient to adjust and simple to operate;

(2) the emptying and the overflowing share one hose, so that the pipeline connection is more convenient;

(3) the mounting port of the interface can be used for mounting an overflow adjusting pipe and can also be used as an emptying port, and the emptying port does not need to be designed independently;

(4) when the device works, the mounting port is provided with the overflow adjusting pipe, and the emptying port is not easy to block;

(5) the paint tray is convenient to clean and does not need to be disassembled.

Fig. 2 is a partial structural view in the direction a of fig. 1.

Detailed Description

The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.

Referring to fig. 1 and 2, the embodiment of the present invention includes a paint tray body 1, a bracket 2, a connector 3, an overflow adjusting pipe 4, a handle 5 and a hose 6.

The paint tray body 1 is mounted on a bracket 2. The paint tray body 1 is provided with a paint containing cavity.

The handle 5 is mounted on the paint tray body 1.

The bottom of the paint tray body 1 is provided with a hole which is matched with the size of the interface 3.

The interface 3 is welded and fixed at the hole of the paint tray body 1. The interface 3 is provided with a mounting port which is communicated with the paint containing cavity. In this embodiment, the top orifice of the mounting opening is flush with the bottom of the paint cavity. Be provided with the internal thread on the installing port, the internal thread can be as far as possible longer, makes things convenient for overflow adjusting pipe 4 to adjust the overflow mouth height through the screw in.

An external thread is arranged on the overflow adjusting pipe 4, and the external thread of the overflow adjusting pipe 4 is connected with the internal thread of the mounting opening, so that the overflow adjusting pipe 4 is mounted on the mounting opening of the interface 3. The mouth of pipe at 4 tops of overflow adjusting pipe is located paint tray body 1, and this mouth of pipe holds the chamber intercommunication with the paint, and is higher than the top drill way of installing port.
