[0036] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0037] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0038] Technologies and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such technologies and equipment should be considered part of the specification.

[0039] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0040] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0041] like Figure 1 As shown, according to one aspect of the present invention, a multi-functional spraying machine is provided, comprising: a main structure, a filter structure 8, a rotating shaft 2, a cleaning component, and a pressure device 14; the main structure has a receiving cavity 7; the filter structure 8 is disposed in the receiving cavity 7, dividing the receiving cavity 7 into a first chamber 16 and a second chamber 15, the first chamber 16 being provided with a spray nozzle 18, and the second chamber 15 being provided with a slag discharge port 3; the rotating shaft 2 is a hollow structure, having an open end 21, a closed end, and a discharge section located between the open end 21 and the closed end, the rotating shaft 2 passing through the second chamber 15. The second chamber 15 is provided with a closed end and an open end 21 extending out of the second chamber 15, and the discharge section is located inside the second chamber 15. The discharge section is provided with multiple discharge holes 13. The open end 21 is connected to the second chamber 15 through the discharge holes 13, and the closed end is used to connect to the rotary drive component 10. The cleaning component is fixed to the discharge section and is used to remove the coating impurities filtered on the filter structure 8 when the rotating shaft 2 rotates. The pressure device 14 can control the pressure in the receiving chamber 7 to make the nozzle 18 spray coating outward or make the slag discharge port 3 discharge the filtered coating impurities outward.

[0042] Specifically, in this embodiment, the filter structure 8 divides the receiving cavity 7 on the main structure into a first chamber 16 and a second chamber 15. The rotating shaft 2 is designed as a hollow structure, with its open end 21 extending out of the second chamber 15. The pressure device 14 can control the receiving cavity 7 to form a negative pressure, causing the paint to be drawn into the discharge section of the rotating shaft 2 through the open end 21, and then enter the second chamber 15 through multiple discharge holes 13 on the discharge section. The paint is then filtered by the filter structure 8, leaving impurities in the second chamber 15. After filtration, the paint enters the first chamber 16 and is sprayed out through the nozzle 18 under negative pressure (at this time, the slag discharge port 3 can be closed), thus achieving the paint spraying effect. During the process of the paint containing impurities entering the first chamber 16 through the filter structure 8 and then being sprayed out through the nozzle 18, the nozzle 18 will not be blocked by impurities in the paint.

[0043] Furthermore, this invention also includes a cleaning component fixedly installed at the discharge section of the rotating shaft 2. When the rotating shaft 2 is driven by the rotating drive component 10, on the one hand, the rotational force can quickly throw the paint inside the hollow structure into the second chamber 15, avoiding the problem of paint clogging inside the rotating shaft 2; on the other hand, during the rotation of the rotating shaft 2, the cleaning component can rotate with the rotating shaft 2, thereby automatically removing the paint impurities that are filtered and adhere to the filter structure 8, avoiding the problem of paint impurities clogging the filter structure 8.

[0044] In addition, the second chamber 15 is also provided with a slag discharge port 3, which allows the pressure device 14 to reverse the direction of air to be drawn in from the nozzle 18, pressurized, and then enter the second chamber 15 from the first chamber 16 through the filter structure 8, or to fill the receiving chamber 7 with compressed air to increase the pressure in the receiving chamber 7 (at this time, the opening end 21 of the rotating shaft 2 and / or the nozzle 18 can be closed), thereby allowing the paint impurities located in the second chamber 15 to be discharged through the slag discharge port 3, realizing the function of automatically cleaning and discharging paint impurities, and avoiding the problem of paint impurities accumulating in the second chamber 15 and causing the filter structure 8 to become clogged.

[0045] As can be seen from the above process, the multi-functional spraying machine provided by this utility model can filter paint while automatically removing and discharging paint impurities on the filter structure 8. On the one hand, it solves problems such as paint machine blockage and high equipment load, thus improving the service life of the spraying machine. On the other hand, it eliminates the need for manual cleaning of sprayed impurities, reducing labor costs and improving spraying efficiency. It is applicable to spraying paints of various compositions or types. Among them, the pressure device 14 can be a pressure pump, the rotary drive component 10 can be a motor, the filter structure 8 can be a filter screen, and the main structure can be a shell structure. The specific design can be made according to actual needs, and this utility model does not limit it in this regard.

[0046] like Figure 1As shown, optionally, the multi-functional spraying machine also includes: a rotary drive 10 and a control module 9; the output end of the rotary drive 10 is connected to the closed end for driving the rotary shaft 2 to rotate; the control module 9 is disposed in the main structure and is electrically connected to the rotary drive 10 and the pressure device 14 respectively, and the control module 9 can control the working state of the rotary drive 10 and the pressure device 14.

[0047] Specifically, in this embodiment, the rotary drive 10 is located at the closed end to drive the rotary shaft 2 to rotate. The control module 9 is connected to the rotary drive 10 and the pressure device 14, allowing the control module 9 to start the rotary drive 10 and the pressure device 14 individually or simultaneously according to work requirements, facilitating spraying or slag removal operations. When the pressure device 14 is a pressure pump, the control module 9 can also control the pressure pump to rotate forward or backward to achieve spraying or slag removal respectively. The control module 9 further improves the automation level of the entire spraying machine, increases spraying efficiency, and reduces labor costs. When the main structure is designed as a shell structure, it can be made of metal, housing the pressure device 14, the control module 9, and the receiving cavity 7 within the shell, improving the protection of the spraying machine's components and further extending the service life of the spraying machine.

[0048] Optionally, such as Figure 1 As shown, both the receiving cavity 7 and the filter structure 8 are cylindrical, and the rotating shaft 2 is located on the central axis of the cylinder. Designing both the receiving cavity 7 and the filter structure 8 as cylindrical, with the cylindrical filter structure 8 nested within the cylindrical receiving cavity 7, results in the first chamber 16 and the second chamber 15 also being annular or cylindrical. When the rotating shaft 2 is located on the central axis of the cylinder, it improves the stability of the entire spraying machine during operation, reduces spraying difficulty, improves spraying quality, and facilitates the structural design and assembly of each component.

[0049] Optionally, such as Figure 1 As shown, the cleaning assembly includes a fixing rod 12 and a spiral scraper 11. The spiral scraper 11 is fixed to the discharge section by the fixing rod 12, and the blade of the spiral scraper 11 is in contact with the inner wall of the filter structure 8.

[0050] Specifically, in this embodiment, the cleaning component is designed such that the spiral scraper 11 is fixed to the discharge section by the fixing rod 12. This allows the rotating shaft 2 to drive the spiral scraper 11 to rotate via the fixing shaft. During this rotation, the tip of the rotating scraper contacts the inner wall of the filter structure 8, effectively scraping away paint impurities adhering to the filter structure 8. The spiral shape of the scraper facilitates the rapid fall of the scraped paint impurities to the bottom of the second chamber 15, preventing them from adhering to the scraper and affecting the cleaning effect. Furthermore, the cylindrical design of the filter structure 8 also facilitates full contact between the tip of the scraper and the inner walls of the filter structure 8, further improving the cleaning effect.

[0051] It should be noted that in this embodiment, the connection position between the fixed rod 12 and the discharge section of the rotating shaft 2, as well as the body of the spiral scraper 11, need to avoid the multiple discharge holes 13 on the discharge section to prevent affecting the discharge of paint from the discharge holes 13. In addition, the spiral scraper 11 can be made of metal to improve its structural strength and ensure the reliability of removing paint impurities from the filter structure 8.

[0052] Optionally, such as Figure 1 As shown, the cleaning assembly also includes an elastic element, and the fixing rod 12 is fixed to the discharge section by the elastic element, so that the cutter head presses against the inner wall of the filter structure 8.

[0053] Specifically, in this embodiment, the fixing rod 12 is positioned in the discharge section by means of an elastic element, which allows the end of the spiral scraper 11 to press firmly against the inner wall of the filter structure 8, thus improving the scraper's cleaning effect. Furthermore, it also prevents the spiral scraper 11 from being damaged by hard impurities during the removal of paint impurities, thereby extending the service life of the spiral scraper 11.

[0054] Optionally, such as Figure 1 As shown, the multi-functional spraying machine also includes: a spray pipe 17, a first valve 4, and a second valve 22. One end of the spray pipe 17 is connected to the first chamber 16, and the other end is a spray nozzle 18. The first valve 4 is used to keep the slag discharge port 3 in an open or closed state. The second valve 22 is used to keep the opening end 21 in an open or closed state. The first valve 4 and the second valve 22 are both connected to the control module 9, and the control module 9 can also control the first valve 4 and the second valve 22 to be in an open or closed state respectively.

[0055] Specifically, in this embodiment, the spray pipe 17 can be supported by a flexible hose to facilitate spraying operations in different environments. The first valve 4 and the second valve 22 facilitate the alternation of spraying and slag removal operations, while the switch on the handle also improves the operator's convenience in using the spraying machine.

[0056] For example, in one embodiment, the pressure device 14 is a pressure pump and is installed at the spray pipe 17, the filter structure 8 is a cylindrical filter screen, the closed end of the rotating shaft 2 is connected to a rotating motor, and the cleaning component is a rotating scraper fixed to the discharge section by a fixing rod 12.

[0057] When spraying is required, first insert the open end 21 of the rotating shaft 2 into the container containing the paint. Then, turn on the pressure pump and the rotating motor through the control module 9, and at the same time close the first valve 4 and open the second valve 22. The pressure pump starts to rotate forward, making the container 7 under negative pressure. The paint enters the discharge section from the open end 21 and enters the second chamber 15 through the discharge hole 13. After being filtered by the filter screen, it enters the spray pipe 17 from the first chamber 16 and is finally sprayed out through the spray nozzle 18.

[0058] When the paint impurities in the second chamber 15 accumulate to a certain capacity, the control module 9 can close the second valve 22, open the first valve 4, and control the pressure pump to reverse, so that external air is drawn in through the spray nozzle, pressurized by the pressure pump, and enters the first chamber 16 and the second chamber 15 (accommodation chamber 7), so that the paint impurities at the bottom of the second chamber 15 are discharged through the slag discharge port 3, realizing the automatic slag discharge process.

[0059] The entire operation process described above is controlled by module 9, which reduces the cost of manual operation and improves the efficiency of the entire process.

[0060] Optionally, such as Figure 1 As shown, the multi-functional spraying machine also includes a pressure sensor 6, which is located at the bottom of the second chamber 15 and connected to the control module 9, for detecting the pressure of the filtered paint impurities.

[0061] Specifically, in this embodiment, a slag storage area 5 can be set at the bottom of the second chamber 15, and a pressure sensor 6 can be set at the bottom of the slag storage area 5. When the paint impurities accumulate to a certain level, the pressure sensor 6 can be triggered, and then the spraying machine can achieve slag discharge operation through the control of the control module 9, which further improves the automation level of the spraying machine.

[0062] Optionally, such as Figure 1 As shown, the spray tube 17 is also equipped with a handle at the position of the spray nozzle 18. A switch connected to the control module 9 is installed on the handle, which is used to control the spraying state of the spray nozzle 18. The handle facilitates the operator's operation of the spray nozzle 18. The switch on the handle can be designed to control the spraying flow rate or spraying range of the spray nozzle 18, etc., and can be designed according to actual needs.

[0063] Optionally, such as Figure 1 As shown, the multi-functional spraying machine also includes: multiple fan blades 1 and a heating element, the multiple fan blades 1 being fixed to the open end 21; the heating element is connected to the control module 9 and is located on the fan blades 1, the control module 9 being able to control the heating element to heat the multiple fan blades 1.

[0064] Specifically, in this embodiment, the arrangement of multiple fan blades 1 allows the rotary drive 10 to simultaneously drive the rotary shaft 2 to remove impurities from the paint on the filter structure 8 and to stir the paint, improving the reusability of the power structure and simplifying the structural design. Furthermore, the inclusion of heating elements on the multiple fan blades 1 allows for simultaneous stirring and heating of the paint, preventing localized overheating near the heating elements that could compromise paint quality. This ensures the paint is in optimal temperature, viscosity, and mixing state for application.

[0065] The heating element can be connected to the control module 9 via the hollow structure of the rotating shaft 2. The control module 9 can control the heating temperature of the coating by controlling the heating power of the heating element, and the specific design can be matched according to the type of coating. In addition, the number of fan blades 1 can be designed to be three, four, etc., and the heating element can be a heating wire arranged inside the fan blades 1.

[0066] Optionally, such as Figure 1 As shown, the multi-functional spraying machine also includes: multiple telescopic brackets 19 and multiple casters 20. The multiple telescopic brackets 19 are respectively connected to the main structure and can extend and retract independently to support the main structure; the multiple casters 20 are respectively set at the bottom of the multiple telescopic brackets 19 to contact the ground.

[0067] Specifically, in this embodiment, by setting multiple independent telescopic rods and multiple casters 20, when the spraying machine is supported on the ground by the casters 20, the entire spraying machine can be adjusted to a balanced state according to the inclination of the ground, thereby improving the stability of the spraying operation. In addition, the casters 20 facilitate the movement of the entire spraying machine. The telescopic support 19 can be designed with three rods to facilitate the balance adjustment of the spraying machine.

[0068] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.

[0069] While specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
