Description

Technical Field

[0001] This application relates to the field of roller coating processing, and more specifically, to a roller coating machine with automatic cleaning. Background Technology

[0002] In the spraying process of roller spraying machines, a stable and relatively small spray flow rate is typically required. The opening range of the spray gun needle and nozzle is very small, often resulting in solidified paint particles adhering to the nozzle exit, reducing the spray flow rate or even clogging the spray gun and affecting continuous spraying production. In such cases, the spray gun needs to be periodically moved out of the production spraying station to a designated cleaning station. The opening range of the spray gun needle and nozzle is increased, and a larger flow rate is used to wash away the paint particles adhering to the nozzle exit. Then, it is returned to the production spraying station to restore the original spray flow rate and continue spraying production. Currently, it is difficult to detect the reduced spray flow rate caused by solidified paint particles adhering to the nozzle exit during the spraying process on current roller spraying machines. By the time the clogging is discovered, it is often too late, resulting in a large number of defective products. Spray gun cleaning can only be performed manually; it is not possible to clean the spray gun during automatic spraying production. Cleaning the spray gun is cumbersome and unsuitable for the need for periodic cleaning of the spray gun nozzles in automatic spraying production.

[0003] Therefore, those skilled in the art need to improve existing roller coating machines to overcome the aforementioned defects. Utility Model Content

[0017] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0018] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0019] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0020] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0021] In addition, the term "multiple" should mean two or more.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-2 As shown, a roller glue machine with automatic cleaning includes a roller glue machine body 1, a tilting frame 2 rotatably mounted on the roller glue machine body 1, and a roller 3 rotatably mounted on the tilting frame 2. A spray gun 7 is rotatably mounted inside the roller 3. A first driving mechanism is provided between the spray gun 7 and the roller 3 to drive its rotation. The spray gun 7 has a working position and a cleaning position. The spray gun 7 is connected to a feeding pipe and a cleaning pipe, respectively. The cleaning pipe is connected to a high-pressure air source. The feeding pipe is connected to a material tank 10. The machine also includes a dust removal mechanism connected to the roller 3.

[0024] The specific structure of the first drive mechanism is not the innovation of this application. Any drive mechanism that can drive the spray gun to rotate can be used here, such as by motor drive.

[0025] Preferably, a turning and unloading motor 4 for driving the turning frame 2 to turn is provided between the turning frame 2 and the body of the rolling machine 1.

[0026] Preferably, a self-rotating motor for driving the rotation of the roller 3 is provided between the roller 3 and the tilting frame 2.

[0027] In order to automatically clean up the waste during the cleaning process online, the dust removal mechanism includes a dust suction hood 6 connected to the roller 3, a conveying pipe 5 connected to the dust suction hood 6, and a filter box 11 connected to the conveying pipe 5. The filter box 11 is provided with an exhaust gas outlet. The dust suction hood 6 is located at the cleaning position of the spray gun 7. Therefore, when the high-pressure gas cleans up the waste, the waste enters the filter box 11 through the dust suction hood 6 and the conveying pipe 5, while the exhaust gas is discharged through the exhaust gas outlet after filtration, and the filtered residue remains in the filter box 11, thereby avoiding environmental pollution.

[0028] In order for the spray gun 7 to automatically switch between the working position and the cleaning position, the high-pressure air source is a gas tank 9 storing high-pressure gas. A control valve is installed on the cleaning pipe and a feeding valve is installed on the feeding pipe. In the working position, the control valve is closed and the feeding valve is open. Conversely, in the cleaning position, the control valve is open and the feeding valve is closed.

[0029] To improve cleaning effectiveness while ensuring processing quality, the spray gun 7 is equipped with a proportional air control valve 8 that adjusts the opening between the needle and the nozzle. By setting the proportional air control valve 8, the opening between the needle and the nozzle is increased in the cleaning position, allowing for automatic cleaning of the spray gun 7 using a large flow of high-pressure gas, thus ensuring the cleaning effect. In the working position, the opening is reduced to ensure the spraying flow rate during production, thereby achieving precise and rapid switching.

[0030] For ease of operation, an electrical control cabinet 13 is also included. The electrical control cabinet 13 is electrically connected to the proportional pneumatic control valve 8, the control valve, the feeding valve, and the first drive mechanism. Operators can control the above-mentioned components from the electrical control cabinet 13. In particular, the cleaning time and cycle can be set.

[0031] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
