[0032] When working: the left side of the liquid outlet pipe 2 is provided with an atomization device to suck the paint in the atomization cylinder 1 into the liquid outlet pipe 2 and atomize and spray out, the paint in the atomization cylinder 1 is sealed by the sealing plate 6 and cannot enter the left side of the liquid outlet pipe 2 through the concentric ring 5, the top of the atomization cylinder 1 is provided with a servo motor, the output end of the servo motor is fixedly connected with the rotating rod 9, and the circumferential surface of the rotating rod 9 is provided with a stirring frame, the servo motor drives the rotating rod 9 to rotate, the rotating rod 9 drives the stirring frame to rotate, and the stirring frame rotates to stir the paint in the atomization cylinder 1, and the rotating rod 9 rotates to drive the limiting ring 10 to rotate;

[0033] The rotation of the limiting ring 10 aligns the limiting groove 11 with the limiting frame 7, after the limiting frame 7 is aligned with the limiting groove 11, the limiting ring 10 releases the limiting of the limiting frame 7, the sealing plate 6 moves to the left under the action of negative pressure on the left side of the liquid outlet pipe 2, the sealing plate 6 moves to the left to drive the limiting frame 7 to move to the left, the limiting frame 7 moves to the left to press the limiting spring 8, the limiting spring 8 is deformed and stores energy under the pressing of the limiting frame 7, and the sealing plate 6 moves to the left to be separated from the contact with the concentric ring 5 and releases the sealing of the liquid outlet pipe 2;

[0034] After the sealing of the liquid outlet pipe 2 is released, the atomization device sucks the paint in the atomization cylinder 1 into the liquid outlet pipe 2 and atomizes and sprays out, after the atomization process is completed, the atomization device stops working, so that the limiting frame 7 moves to the right under the action of the elastic force of the limiting spring 8 and resets, the limiting frame 7 moves to the right to drive the sealing plate 6 to move to the right, and the sealing plate 6 moves to the right to contact the inner wall of the concentric ring 5 and restore the sealing of the liquid outlet pipe 2.

[0035] Reference Figures 1-7 On the basis of the above embodiment, another embodiment of the present application further comprises a crushing assembly and a feeding assembly, the crushing assembly is used for crushing the caked paint, and the feeding assembly is used for feeding the bonding agent into the atomization cylinder 1, the crushing assembly comprises a pressing frame 121, a reset disc 122, a reset spring 123 and a linkage rod 124, the pressing frame 121 is slidingly installed on the circumferential surface of the rotating rod 9, the reset disc 122 is fixedly installed at the bottom of the limiting ring 10, the reset spring 123 is arranged between the pressing frame 121 and the reset disc 122, and the reset spring 123 can support the pressing frame 121, and the linkage rod 124 is rotatably penetrated through the circumferential surface of the atomization cylinder 1, so that the caked paint is crushed into small particles by mechanical force through the reciprocating movement of the pressing frame 121, and the small particles are mixed into the paint again or are atomized together with the paint, so that the continuity of the paint supply is ensured.

[0036] The broken assembly further comprises a fishing frame 125, a fishing spring 126, a fishing hole 127 and a guide frame 128, the fishing frame 125 is slidingly installed on the surface of the pressing frame 121, the fishing spring 126 is arranged between the fishing frame 125 and the pressing frame 121, the fishing hole 127 is opened in the left and right walls of the fishing frame 125, and the fishing frame 125 is fixedly installed on the front side of the fishing frame 125. The agglomerated paint fished by the fishing frame 125 can flow to the bottom of the pressing frame 121 for secondary crushing. The agglomerated paint on the edge of the pressing frame 121 can be continuously fished and crushed by the rotation of the fishing frame 125. The secondary crushing can avoid the unrefined agglomerated paint entering the liquid outlet pipe 2, thereby improving the crushing effect of the agglomerated paint. The left side of the linkage rod 124 is made of rubber material.

[0037] The fishing frame 125 is in contact with the inner wall of the atomizing cylinder 1. The rear top of the pressing frame 121 is provided as an arc surface. The arc surface of the rear top of the pressing frame 121 can reduce the friction when the pressing frame 121 is in contact with the linkage rod 124. The front side of the guide frame 128 is provided as an inclined surface. The inclined surface of the front side of the guide frame 128 can improve the fishing effect of the guide frame 128.

[0038] The discharging assembly comprises a discharging frame 131, a curved panel 132, a discharging pipe 133 and a quantity control frame 134. The discharging frame 131 is fixedly installed on the circumferential surface of the atomizing cylinder 1.

The quantity control frame 134 slidingly penetrates the circumferential surface of the discharging frame 131. A spring is arranged between the linkage rod 124 and the atomizing cylinder 1. The discharging frame 131 is internally provided with an adhesive. The intermittent feeding of the adhesive into the atomizing cylinder 1 in multiple small doses can ensure the full fusion of the adhesive and the paint, thereby avoiding the agglomeration of the paint caused by the excessive local concentration of the adhesive.

[0039] The discharging assembly further comprises a floating block 135 and a quantity control hole 136. The floating block 135 is fixedly installed on the bottom of the quantity control frame 134. The quantity control hole 136 is opened in the circumferential surface of the linkage rod 124. A one-way valve is arranged in the discharging pipe 133. The one-way valve can prevent the paint from flowing back into the discharging frame 131. The natural movement of the floating block 135 with the falling liquid level can realize the real-time observation of whether the adhesive is insufficient.

[0040] The curved panel 132 is in contact with the discharging pipe 133. A sealing ring is arranged between the discharging frame 131 and the quantity control frame 134. The linkage rod 124 cannot rotate, so the curved panel 132 cannot rotate. The adhesive is temporarily stopped from being fed. The automatic temporary stop can timely stop before the adhesive is exhausted, thereby ensuring that the adhesive performance of each batch of paint meets the standard and further avoiding the abnormal performance of the paint caused by the idle rotation of the curved panel 132 after the adhesive is exhausted.

[0041] When working, the rotation of the rotating rod 9 drives the pressing frame 121 to rotate, and the rotation of the pressing frame 121 makes the arc surface of the pressing frame 121 contact and extrude the linkage rod 124, and the linkage rod 124 is extruded by the pressing frame 121 to rotate, and the pressing frame 121 is moved downward by the reaction force of the extruded linkage rod 124, and the downward movement of the pressing frame 121 pulls the reset spring 123, and the reset spring 123 is deformed and stores energy by the pulling of the pressing frame 121;

[0042] The continuous rotation of the pressing frame 121 will be separated from the contact with the linkage rod 124, and after the pressing frame 121 is separated from the contact with the linkage rod 124, the pressing frame 121 is moved upward by the elastic force of the reset spring 123 to reset, and the reciprocating movement of the pressing frame 121 breaks the agglomerated paint at the bottom of the atomizing cylinder 1, and the rotation of the pressing frame 121 drives the fishing frame 125 to rotate, and the rotation of the fishing frame 125 scrapes the agglomerates at the inside of the bottom of the atomizing cylinder 1, and the agglomerates at the inside of the bottom of the atomizing cylinder 1 are scraped and guided by the inclined surface of the guide frame 128 to enter the inside of the fishing frame 125 through the fishing hole 127;

[0043] Meanwhile, the rotation of the pressing frame 121 makes part of the agglomerated paint flow from the bottom of the pressing frame 121 to the edge of the pressing frame 121, and the rotation of the fishing frame 125 continuously fishes the agglomerated paint at the edge of the pressing frame 121, and the agglomerated paint fished by the fishing frame 125 flows to the bottom of the pressing frame 121 for secondary breaking.

[0044] The rotation of the linkage rod 124 extrudes the clock spring, and the clock spring is deformed and stores energy by the extrusion of the linkage rod 124, and the rotation of the linkage rod 124 drives the curved plate 132 to rotate, and the rotation of the curved plate 132 separates from the contact with the discharging pipe 133 and unseals the discharging pipe 133, and after the pressing frame 121 is separated from the contact with the linkage rod 124, the linkage rod 124 is reset by the elastic force of the clock spring;

[0045] The reset of the linkage rod 124 contacts the discharging pipe 133 and seals the discharging pipe 133 again, and the reciprocating movement of the curved plate 132 shields the discharging pipe 133 to make the adhesive in the discharging frame 131 be intermittently discharged into the inside of the atomizing cylinder 1 through the discharging pipe 133, and when the adhesive in the discharging frame 131 gradually decreases, the float 135 moves downward with the decrease of the adhesive liquid level, and the downward movement of the float 135 drives the control frame 134 to move downward;

[0046] When the control frame 134 moves downward, it will contact the control hole 136 and limit the linkage rod 124. The linkage rod 124 cannot rotate due to the limitation of the control frame 134, so that the curved plate 132 cannot rotate, and the adhesive is paused.

[0047] The above merely illustrates the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacements or changes according to the technical scheme and the inventive concept of the present application within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application.
