Detailed Embodiments

[0020] The following will describe in detail the embodiments of the present application in conjunction with the drawings and embodiments, so as to fully understand the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects and implement accordingly.

[0021] Example 1 The current filtering equipment needs to regularly replace the filter element structure to ensure the smooth filtering of paint. Since the continuous production of paint cannot be achieved, the processing efficiency of paint is affected. This example provides a paint filtering device for paint production and processing, as Figures 1-8 shown, which includes a box body 1. An upper material guiding bin 2 and a lower material guiding bin 3 are installed in the middle of the box body 1. A filter mechanism 5 that can work in a rotation mode is arranged between the upper material guiding bin 2 and the lower material guiding bin 3. A discharge pipe 4 extending out of the box body 1 is connected and installed on the lower material guiding bin 3. The filtered paint will be temporarily stored in the lower material guiding bin 3 and then discharged through the discharge pipe 4. The filter mechanism 5 includes a frame 51. Two groups of filter plates 52 are rotatably installed in the frame 51, and two groups of servo motors 53 for driving the corresponding filter plates 52 to rotate are installed at intervals at the edge of the frame 51. The top end of the filter plate 52 is close to the bottom end of the upper material guiding bin 2, and the bottom end of the filter plate 52 is close to the top end of the lower material guiding bin 3, which can ensure that the paint flows out from the gap therebetween (the gaps formed between the upper material guiding bin 2 and the filter plate 52, and between the lower material guiding bin 3 and the filter plate 52); starting the servo motor 53 can drive the corresponding filter plate 52 to flip 180°, making its front side face up or down. A translation mechanism 6 for driving the frame 51 to move horizontally is arranged in the box body 1. During the working state, one group of filter plates 52 is located between the upper material guiding bin 2 and the lower material guiding bin 3, and the other group of filter plates 52 can be flipped to face down. Taking Figure 1 the up-down, left-right, and front-back directions as the reference, during the long-term filtering process, the filter holes of the filter plate 52 on the left side will be blocked by the solid particles that are not fully ground, affecting the filtering efficiency of the paint; at this time, the translation mechanism 6 can be used to drive the frame 51 to move to the left, driving the filter plate 52 on the right to move to the left until it is located between the upper material guiding bin 2 and the lower material guiding bin 3. At this time, the paint in the upper material guiding bin 2 will be filtered through the filter plate 52 on the right side. The two groups of filter plates 52 can work alternately to achieve the continuous production of paint and improve the production efficiency of paint; while the filter plate 52 on the right side is working, the filter plate 52 on the left side is in an idle state. The servo motor 53 is used to drive the filter plate 52 on the left side to flip 180° to make its front side face down, which is convenient for subsequent dredging work.

[0022] The filter plate 52 facing downward, under the action of gravity, part of the paint and blockages in its filter holes will flow out naturally, but most of the blockages will still remain in the filter holes. In order to completely discharge the blockages in the filter holes, a dredging mechanism 7 for double dredging of the filter plate 52 directly below is provided at positions on both sides of the upper material guide bin 2 in the box body 1; the dredging mechanism 7 includes a rotating shaft 79 that is installed through and rotates in the upper material guide bin 2, and turntables 78 are fixed at both ends of the rotating shaft 79. The turntables 78 are located on the left and right sides of the upper material guide bin 2, an eccentric rod 77 is fixed to the outer end of the turntable 78, the push-pull rod 77 is close to the edge of the turntable 78, a swing rod 76 is rotatably installed on the eccentric rod 77, the other end of the swing rod 76 is rotatably installed with a push-pull rod 75, a movable sleeve rod 73 is fixed on the push-pull rod 75, the top end of the movable sleeve rod 73 is slidably installed with a vertical rod 74 fixed to the top wall of the box body 1. The vertical rod 74 is installed vertically, and a vibration block 72 is fixed to the bottom end of the movable sleeve rod 73. The vibration block 72 can be made of a rubber block. Control the power mechanism 8 to drive the rotating shaft 79 to rotate, thereby driving the turntable 78 to rotate, realizing the rotation of the eccentric rod 77 around the rotating shaft 79 as the central axis. Through the transmission of the swing rod 76, it can drive the movable sleeve rod 73 to move reciprocally in the vertical direction, and then make the vibration block 72 continuously collide with the filter plate 52 facing downward, making the filter plate 52 vibrate, and quickly and fully discharging the blockages in the filter holes, realizing the dredging of the filter plate 52 on the left; similarly, the vibration block 72 on the right can also be used to dredge the filter plate 52 on the right; while dredging one group of filter plates 52, it does not affect the normal operation of the other group of filter plates 52. The two groups of filter plates 52 can work alternately, realizing the continuous production of paint and improving the production efficiency of paint.

[0023] In order to enhance the dredging effect on the filter plate 52, a pagoda-shaped rubber cover 71 is fixed to the outer end of the movable sleeve rod 73, and the vibration block 72 is located inside the pagoda-shaped rubber cover 71. When the movable sleeve rod 73 moves downward, the pagoda-shaped rubber cover 71 first contacts the top of the filter plate 52. As the movable sleeve rod 73 continues to move downward, the pagoda-shaped rubber cover 71 begins to deform, and the air inside is squeezed downward to dredge the filter plate 52. Cooperating with the vibration of the vibration block 72, the dredging effect can be further improved.

[0024] The above-mentioned upper material guide bin 2 is provided with a power mechanism 8 for driving the rotating shaft 79 to rotate; the power mechanism 8 includes a servo motor three 81 installed at the outer end of the upper material guide bin 2, the output end of the servo motor three 81 is fixed with a main gear 82, and the outer end of the main gear 82 is meshed with a sub-gear 83 fixedly installed through the rotating shaft 79. Start the servo motor three 81, drive the main gear 82 to rotate, and then drive the sub-gear 83 to rotate, then the rotating shaft 79 can be driven to rotate, and the dredging mechanism 7 can work.

[0025] The aforementioned translation mechanism 6 comprises connecting blocks 61 symmetrically fixed to either side of the top of the frame 51. Screws 62 are threadedly mounted on the connecting blocks 61 and rotatably connected to the inner wall of the housing 1. Two sets of servo motors 63 are mounted on the outer end of the housing 1 to drive the corresponding screws 62. Activating the servo motors 63 rotates the screws 62, which in turn drives the connecting blocks 61 left and right, thereby adjusting the position of the filter mechanism 5 and shifting the filter plate 52 left or right.

[0026] Furthermore, a stirring rod 10 is fixed to the portion of the rotating shaft 79 corresponding to the upper guide bin 2. When the rotating shaft 79 rotates, the stirring rod 10 is driven to rotate, stirring the paint in the upper guide bin 2, improving the fluidity of the paint, and helping to speed up the filtering efficiency of the filter plate 52 on the paint.

[0027] Example 2 Based on Example 1, Figures 5-6 The lower guide hopper 3 is provided with an ejection mechanism 9. The ejection mechanism 9 comprises a support plate 91 fixed to the inner wall of the lower guide hopper 3. At least two sets of hydraulic rods 92 are mounted side by side on the support plate 91. The movable ends of the hydraulic rods 92 are fixed to a movable plate 94. The movable plate 94 is provided with a plurality of strip-shaped openings 93 for rapid paint flow. The top of the movable plate 94 is fixed with a plurality of ejector pins 95. The number of ejector pins 95 corresponds to the number of filter holes on the filter plate 52. In the initial state, as shown in FIG. Figure 6 As shown, ejector pins 95 are located in the filter holes of the filter plate 52 to prevent large particles from directly entering the filter holes and causing complete blockage of the filter holes. The ejector pins 95 can slightly lift the large particles to form gaps, thereby preventing complete blockage of the filter holes and allowing paint to flow through the filter holes, thereby reducing the rotation frequency of the filter plate 52. When the filter plate 52 needs to be unblocked, the hydraulic rod 93 is activated to drive the movable plate 94 downward, causing the ejector pins 95 to move downward and disengage from the filter holes, facilitating the movement of the filter plate 52.
