Attached Figure Description

[0016] Figure 1 This is a three-dimensional schematic diagram of the present invention;

[0017] Figure 2 This is an exploded view of the present invention;

[0018] Figure 3 This is a cross-sectional view of the present invention. Detailed Implementation

[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] like Figures 1 to 3 As shown, this utility model discloses an anti-settling device for a coating material basin, including a material basin 1. The material basin 1 is provided with a receiving groove 11 that can hold the coating material and allow a material roller 2 to extend into it. A material-spreading gap 3 is left between the lower part of the material roller 2 and the bottom surface of the receiving groove 11. The material basin 1 is slidably provided with a material-spreading component 4 that can move along the length direction of the receiving groove 11. The material-spreading component 4 extends into the material-spreading gap 3.

[0021] In one embodiment, the material basin 1, the conveying roller 2, and the moving mechanism 5 are all connected to the mounting bracket (not shown in the figure). The conveying roller 2 can evenly distribute the coating in the material basin 1 onto the corresponding substrate through rotation. The lower part of the conveying roller 2 extends into the receiving groove 11 to ensure continuous feeding. The dividing element 4 extends into the dividing gap 3 and moves along the length of the receiving groove 11 under the action of the moving mechanism 5. The dividing element 4 can also be moved along the length of the receiving groove 11 by manual means, thereby improving the fluidity of the coating, reducing the sedimentation of microparticles, and maintaining good coating performance.

[0022] By inserting the scouring element 4 into the scouring gap 3, the coating material in the scouring gap 3 is agitated, thereby maintaining a uniform mixing state of the coating material in the entire receiving tank 11, reducing or eliminating unevenness and defects caused by sedimentation, and ensuring the quality and consistency of coating.

[0023] The material-spreading component 4 includes a material-spreading rod 41 and a paddle 42 disposed at one end of the material-spreading rod 41, the paddle 42 extending into the material-spreading gap 3.

[0024] The arrangement of the paddle 42 increases the disturbance effect of the paddle component 4 on the paint during movement. Compared to a straight paddle component 4, the paddle 41 can more effectively push and mix the paint, thereby better preventing sedimentation and improving the overall uniformity of the paint.

[0025] The shape of the portion of the cutting rod 41 that extends into the receiving groove 11 matches the shape of the inner wall of the receiving groove 11.

[0026] The geometry of the portion of the marking rod 41 extending into the receiving groove 11 is designed to match the contour of the inner wall of the receiving groove 11. Specifically, when the cross-section of the receiving groove 11 is semi-circular or elliptical, the shape of the portion of the marking rod 41 extending into the receiving groove 11 is an arc that matches the shape of the inner wall of the receiving groove; similarly, when the cross-section of the receiving groove 11 is rectangular, the shape of the portion of the marking rod 41 extending into the receiving groove 11 is an L-shape that matches the shape of the inner wall of the receiving groove 11. By matching the shape of the portion of the marking rod 41 extending into the receiving groove 11 with the shape of the inner wall of the receiving groove 11, it is ensured that the outer edge of the marking rod 41 is consistent with the curve of the inner wall of the receiving groove. During its movement, it can stay close to the side wall, optimizing the space utilization of the receiving groove 11 and reducing dead corner areas.

[0027] The propulsion rod 41 includes a first connecting rod 411, a second connecting rod 412 connected to the first connecting rod 411 and arranged parallel to the side wall of the receiving groove 11 extending along the length direction, and a third connecting rod 413 connected to the second connecting rod 412 and arranged parallel to the bottom surface of the receiving groove 11. The paddle 42 is provided at the end of the third connecting rod 413.

[0028] In one embodiment, the first connecting rod 411 is used to transmit power from the moving mechanism 5, the second connecting rod 412 is arranged parallel to the side wall of the receiving groove 11 to maintain the stability of the padding component 4 during the movement, and the third connecting rod 413 is arranged parallel to the bottom surface of the receiving groove 11 to ensure that the padding 41 can be close to the bottom surface for effective stirring, to ensure that the microparticles in the coating are in a suspended state, and to maintain the uniformity of the coating.

[0029] The two side walls of the receiving groove 11 extending along the length direction have arc surfaces or slopes that allow the paint to converge.

[0030] The curved or inclined surfaces on the sidewalls can guide the paint to converge towards the marking gaps 3, reducing the paint's retention near the sidewalls and ensuring that the marking components 4 can better maintain the uniform mixing state of the paint in the receiving tank 11.

[0031] The bottom surface of the receiving groove 11 is a plane.

[0032] The planar bottom surface of the receiving groove 11 can reduce the interference between the paddle 42 and the bottom surface of the receiving groove 11, while making it easier to control the height of the scouring gap 3, which helps the scouring component 4 maintain stable paint flow.

[0033] The axis of the conveyor roller 2 is parallel to the bottom surface of the receiving groove 11.

[0034] The axis of the conveyor roller 2 is set parallel to the bottom surface of the receiving groove 11, which can reduce the interference between the paddle 42 and the conveyor roller 2, while enabling the conveyor roller 2 to pick up the paint evenly when rotating and transfer it stably to the substrate, thus ensuring the consistency of the coating thickness.

[0035] In one embodiment, the two side walls of the receiving groove 11 extending along the length direction are inclined surfaces, and the bottom surface of the receiving groove 11 is a plane. The part of the dividing rod 41 that extends into the receiving groove 11 is arranged parallel to the inner wall of the receiving groove 11 and leaves a gap, which can reduce the instability caused by the tilting or offset of the dividing rod 41 and improve the stability of the dividing rod 41 during the movement.

[0036] The cutting component 4 is connected to a moving mechanism 5 that can drive the cutting component 4 to move.

[0037] The moving mechanism 5 is responsible for driving the scouring component 4 to reciprocate along the length of the receiving tank 11, ensuring that it can effectively agitate the coating throughout the entire stroke and prevent microparticle deposition.

[0038] The moving mechanism 5 includes a sliding pair 52 whose sliding direction is consistent with the length direction of the receiving groove 11 and its driving mechanism. One end of the cutting component 4 is connected to the sliding component of the sliding pair 52.

[0039] In one embodiment, the moving mechanism 5 is a rodless cylinder 51 with a slider arranged along the length of the receiving groove 11, and one end of the agitator 4 is connected to the slider. The rodless cylinder 51, as a compact linear motion actuator, drives the slider through an internal piston and provides it with stable, high-precision linear motion. The specific structure of the rodless cylinder 51, which enables the functions required by this patent, has been disclosed in prior art document CN208503137U, and therefore will not be described in detail here. Through the precise linear motion provided by the rodless cylinder 51, the agitator 4 can reciprocate at a preset speed and stroke, ensuring that the agitator 41 can effectively agitate the coating and prevent sedimentation.

[0040] The moving mechanism 5 can also be implemented in other ways, such as by driving the moving block to move through a motor, ball screw or synchronous belt, and the cutting component 4 is connected to the moving block, thereby realizing the function of driving the cutting component 4 to move.

[0041] The direction of movement of the paddle 42 is parallel to the length direction of the material basin 1 and the axial direction of the material roller 2.

[0042] The movement direction of the paddle 42 is parallel to the length direction of the material basin 1 and the axial direction of the conveyor roller 2, which ensures that the paddle 42 remains stable during operation.

[0043] The working principle in one embodiment is as follows: The pneumatic valve is opened, and compressed air enters one end of the rodless cylinder 51, pushing the piston slider 52 forward along the slide rail. The slider 52 drives the material-carrying component 4 and its paddle 41 to move forward synchronously. During this process, the paddle 41 agitates the coating material, preventing microparticles from settling. When the slider 52 reaches a preset position, the control system switches the direction of the pneumatic valve, allowing compressed air to enter the rodless cylinder 51 from the other end, pushing the slider 52 to move in the opposite direction, completing one full reciprocating motion cycle.
