[0050] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0051] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] In the present invention, unless otherwise clearly stipulated and limited, the first feature being "on" or "below" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through another feature between them.

[0053] In the description of this embodiment, the terms "upper", "lower" and other positions or positional relationships are based on the positions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0054] This embodiment provides a spray feeding device, such as Figure 1 As shown, the spray feeding device includes a storage box 1, a heating unit 2 and a stirring unit 3.

[0055] The interior of the storage box 1 is provided with an upper storage chamber 11 and a lower storage chamber 12 in sequence along the vertical direction. The upper storage chamber 11 and the lower storage chamber 12 are separated by a sieve plate 10. The upper storage chamber 11 is provided with an inlet 1011, and the lower storage chamber 12 is provided with an outlet 1021.

[0056] Paint is added into the upper storage chamber 11 through the feed port 1011 , and the paint can pass through the filtering effect of the sieve plate 10 and enter the lower storage chamber 12 downward, and then be discharged from the discharge port 1021 .

[0057] In this embodiment, the feed port 1011 is located at the top of the storage box 1, and the discharge port 1021 is located at the bottom of the storage box 1. The feed port 1011 is located at the top of the storage box 1, and as much paint as possible can be put in, and the discharge port 1021 is located at the bottom of the storage box 1, which can prevent the paint from remaining in the storage box 1.

[0058] The heating unit 2 is used to heat the upper material storage cavity 11. The heat generated by the heating unit 2 can heat the paint in the upper material storage cavity 11 and reduce solidification into agglomerates.

[0059] The stirring unit 3 is used to stir the coating material in the lower storage chamber 12. After the coating material passes through the sieve plate 10 and enters the lower storage chamber 12, it is stirred by the stirring unit 3 before being discharged.

[0060] The spray feeding device integrates three modes: heating, screen filtering and stirring, which can effectively reduce the particle size.

[0061] Since large particles of paint cannot pass through the sieve plate 10, large particles of paint tend to gather on the surface of the sieve plate 10, hindering the downward movement of the paint. Therefore, in the preferred embodiment of the present invention, the spray feeding device further includes a pushing unit 4, which is connected to the sieve plate 10 and reciprocates the sieve plate 10. The sieve plate 10 is moved by the pushing unit 4, so that the large particles of paint left on the surface of the sieve plate 10 and the surrounding environment vibrate with each other and then decompose, thereby accelerating the passage through the sieve plate 10.

[0062] It should be noted that the sieve plate 10 can move in the vertical direction or in the horizontal direction. When the sieve plate 10 vibrates in the vertical direction, there is space for movement in the vertical direction, and the paint can easily press the sieve plate 10 downward and deform it. Therefore, in this embodiment, the sieve plate 10 is preferably controlled to vibrate in the horizontal direction.

[0063] Specifically, a limiting groove 100 extending in a horizontal direction is provided in the storage box 1, and the sieve plate 10 is supported on the limiting groove 100. The limiting groove 100 is also provided with an opening. The pushing unit 4 is connected to the sieve plate 10 through the opening and drives the sieve plate 10 to reciprocate along a first horizontal direction, thereby reducing collision between the sieve plate 10 and the storage box 1.

[0064] It is understandable that the limit groove 100 is connected to the upper storage cavity 11. In order to prevent the paint from gathering after flowing into the limit groove 100, the inner diameter of the lower end of the upper storage cavity 11 is gradually narrowed, so that the paint is not easy to spread to the limit groove 100 when flowing along the inner wall of the upper storage cavity 11.

[0065] like Figure 2 As shown, the pushing unit 4 includes a first driver 43 , one end of which is fixedly connected to the storage box 1 , and the other end of the first driver 43 is drivingly connected to the screen plate 10 to enable the screen plate 10 to move.

[0066] The pushing unit 4 further comprises a transmission mechanism 42 connected between the sieve plate 10 and the first driver 43 , and the movement of the sieve plate 10 is made more stable and reliable by the transmission structure 42 .

[0067] The transmission mechanism 42 includes a movable rod 420 , a sliding block 421 , a fixing block 422 , a first connecting rod 423 , a second connecting rod 424 , and a connecting rod 425 .

[0068] The movable rod 420 is connected to the output end of the first driver 43 to move in the vertical direction, and the first driver 43 can drive the movable rod 420 to reciprocate up and down. The slider 421 is slidably arranged on the movable rod 420 along the horizontal first direction, and the fixed block 422 is fixedly connected to the storage box 1, and the fixed block 422 never moves. The first connecting rod 423 is pivoted between the first end of the slider 421 and the fixed block 422, the first end of the second connecting rod 424 is pivoted to the second end of the slider 421, the second end of the second connecting rod 424 is pivoted to the first end of the connecting rod 425, and the second end of the connecting rod 425 is connected to the screen plate 10, wherein when the movable rod 420 moves in the vertical direction, the slider 421, the first connecting rod 423, the second connecting rod 424, and the connecting rod 425 move synchronously.

[0069] Preferably, the first end and the second end of the movable member 421 are collinear along the second horizontal direction, and the second horizontal direction and the first horizontal direction are perpendicular to each other.

[0070] like Figure 2 As shown, after the first driver 43 drives the movable rod 420 to move downward, the slider 421 moves to the right under the action of the first connecting rod 423, the first connecting rod 423 rotates in the clockwise direction, the second connecting rod 424 rotates in the counterclockwise direction, the connecting rod 41 moves to the right under the action of the second connecting rod 424, and then the screen plate 10 moves to the right. Similarly, it can be seen that after the first driver 43 drives the movable rod 420 to move upward, the slider 421 moves to the left under the action of the first connecting rod 423, the first connecting rod 423 rotates in the counterclockwise direction, the second connecting rod 424 rotates in the clockwise direction, the connecting rod 425 moves to the left under the action of the second connecting rod 424, and then the screen plate 10 moves to the left.

[0071] Optionally, the connecting rod 425 passes through a positioning block 411 to restrict the connecting rod 425 to move only in a straight line.

[0072] Simply relying on the first driver 43 cannot always ensure that the movable rod 420 keeps moving in the vertical direction. The movable rod 420 is easily offset in the storage box 1, which will cause damage to the first connecting rod 423 and the second connecting rod 424 in the long run. Therefore, in this embodiment, the transmission mechanism 42 also includes a first guide rod 426. The first guide rod 426 is arranged in the vertical direction, and one end of the movable rod 420 is slidably sleeved on the first guide rod 426. When the first driver 43 drives the movable rod 420 to move, the movable rod 420 is always guided by the first guide rod 426.

[0073] See also Figure 3-Figure 4 The heating unit 2 includes a heater 21, and the heater 21 abuts against and heats the outer surface of the first side wall of the upper storage cavity 11. It should be noted that the paint enters the upper storage cavity 11 and contacts the inner surface of the first side wall.

[0074] In this embodiment, the heater 21 is an electric heating tube, and its heating temperature is selected within a suitable range according to the physical and chemical properties of the coating, which is not limited in this embodiment.

[0075] However, if the heater 21 heats only one area of ​​the first side wall, it will not be able to meet the heating requirements of all the paint in the upper storage chamber 11. Therefore, in this embodiment, the heater 21 is movable on the outer surface of the first side wall, so as to heat the paint in a larger range and prevent the paint from agglomerating.

[0076] Furthermore, the heating unit 2 further includes a second guide rod 20 , a bracket 22 , a turntable 23 and a second driver 24 .

[0077] The second guide rod 20 extends in a straight line, the bracket 22 is slidably disposed on the second guide rod 20, the heater 21 is connected to one side of the bracket 22, the turntable 23 is engaged with the other side edge of the bracket 22, and the rotation axis of the turntable 23 is perpendicular to the second guide rod 20; the second driver 24 drives the turntable 23 to rotate.

[0078] It is understandable that the extension direction of the second guide rod 20 is the movement direction of the bracket 22, which defines the movement range of the heater 21. In this embodiment, the second guide rod 20 extends along a straight line, so that the heater 21 reciprocates on a line segment.

[0079] It should be noted that, in this embodiment, the first driver 43 selects to use a linear cylinder, and the second driver 24 selects to use a rotary cylinder. In other embodiments, the first driver 43 selects to use a linear cylinder, and can also be directly connected to the sieve plate 10 through the output end of the first driver 43 to reduce production costs.

[0080] In this embodiment, the bracket 22 is slidably mounted on the second guide rod 20 and is provided with a plurality of spaced teeth 221, the arrangement direction of the teeth 221 being consistent with the extension direction of the second guide rod 20. The rotation axis of the turntable 23 is perpendicular to the second guide rod 20, and the turntable 23 is provided with a conductive strip 231 engaged with the teeth 221. When the turntable 23 rotates counterclockwise or clockwise, the teeth 221 are moved by the conductive strip 231.

[0081] The stirring unit 3 includes a third driver 31 and a stirring rod 32 . The third driver 31 drives the stirring rod 32 to rotate, thereby stirring the paint flowing through the stirring rod 32 .

[0082] The working principle of the spray feeding device provided in this embodiment is:

[0083] The paint is added into the upper storage chamber 11 from the feed port 1011, the heater 21 of the heating unit 2 is turned on to heat the first side wall, and then the second driver 24 is turned on. At this time, the heater 21 will be active to heat different areas on the first side wall, and the first driver 43 is turned on. At this time, the sieve plate 10 begins to vibrate in the horizontal first direction to accelerate the paint to pass through the sieve plate 10 to avoid blockage and agglomeration, and then the third driver 31 is turned on, and the stirring rod 32 stirs the paint entering the lower storage chamber 12 to keep the paint in good dispersion before it exits the discharge port 1021.

[0084] Embodiment 2:

[0085] This embodiment provides a sprayer, which includes the spray feeding device provided in the first embodiment, which is not described in detail in this embodiment.

[0086] like Figure 5 As shown, the spraying machine further comprises a delivery pump 5 and a spray head 6 , wherein the input of the delivery pump 5 is connected to the discharge port 1021 of the spray feeding device, and the input end of the spray head 6 is connected to the output end of the delivery pump 5 .

[0087] After the delivery pump 5 delivers the paint from the discharge port 1021 to the spray head 6, the paint is sprayed out from the output end of the spray head 6 to perform a spraying operation.

[0088] Usually, spraying in a single direction cannot meet the spraying requirements. In this embodiment, the spraying machine further includes an angle adjuster 7 , which is connected to the spray head 6 and is used to adjust the rotation angle range of the spray head 6 .

[0089] In this embodiment, the angle adjuster 7 is used to adjust the spraying angle of the spray head 6 relative to the horizontal plane.

[0090] In order to improve the mobility of the sprayer, the sprayer further comprises a housing 8 , on which the spraying feeding device, the delivery pump 5 and the spray head 6 are all arranged, and a plurality of universal wheels 81 are arranged at the bottom of the housing 8 .

[0091] Furthermore, in order to facilitate pushing the shell 8 , a handle 82 is provided on the shell 8 .

[0092] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
