Technical Field

[0001] The utility model relates to the technical field of metal plate spraying, in particular to a paint spraying recovery device for metal plate coating. Background Art

[0002] Painting is a systematic project, which includes three basic processes: surface treatment of the object to be coated before painting, coating process and drying, as well as the design of a reasonable coating system, selection of suitable coatings, determination of good working environment conditions, and important links such as quality, process management and technical economy. Metal plates are a commonly used processing object. In order to prevent their surface from rusting, the surface of the metal plates needs to be sprayed with paint.

[0003] The patent document with the prior art publication number CN217450649U provides a paint spray recovery device for industrial coating, including a base plate, the top outer wall of the base plate is fixedly connected with a symmetrically arranged first support rod, the tops of the two first support rods are fixedly connected with the same workbench, the inner wall of the opposite side of the workbench is fixedly connected with a symmetrically arranged positioning mechanism; the bottom outer wall of the workbench is fixedly connected with a drainage hood, and the inner walls on both sides of the drainage hood are fixedly connected with symmetrically arranged guide plates. After the spraying work is completed, the paint that has not been sprayed on the surface of the workpiece flows into the paint box through the drainage hood and the guide plate, achieving the effect of recycling the paint, and through the metal filter, it can filter the solid impurities contained in the paint, avoiding the solid impurities from affecting the spraying quality of the workpiece surface during the spraying process. It is more practical and suitable for wide promotion and use. Although the device has good beneficial effects, there are still the following problems: the filter screen of the device is in a fixed installation state, so the paint will always fall on the same position of the filter screen when it flows to the filter screen, and the paint is generally viscous and has strong adhesion, so the paint flow falls on the same position of the filter screen for a long time, which is easy to cause the filter screen to be blocked, affecting the filtration and recovery of the paint. In view of this, we propose a paint spray recovery device for metal plate coating. Utility Model Content

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0020] Example:

[0021] This embodiment discloses a paint spray recovery device for metal plate coating, see Figures 1 to 3 , including a paint spraying machine 1 and a filtering and recycling mechanism 2.

[0022] like Figure 1 As shown in Figure 2, the paint sprayer 1 includes a chassis 101, a paint spraying mechanism 102 is provided in the top inner cavity of the chassis 101, a placement rack 103 is provided at the bottom of the paint spraying mechanism 102, and two guide plates 104 inclined toward the bottom center of the chassis 101 are symmetrically provided at the bottom of the placement rack 103; in this embodiment, the paint sprayer 1 is an existing metal plate painting equipment on the market. When painting, the metal plate is first placed on the placement rack 103, and the paint spraying mechanism 102 is driven by an external control mechanism to spray paint on the surface of the metal plate. Excess paint will pass through the placement rack 103 and flow into the filtering and recovery mechanism 2 through the two guide plates 104 for filtration and recovery.

[0023] like Figures 1 to 3 As shown, the filtering and recovering mechanism 2 is disposed in the inner cavity at the bottom of the chassis 101 .

[0024] Specifically, Figure 1 , Figure 2As shown, the filtering and recycling mechanism 2 includes a filter screen 201, a motor 202 and a cylindrical cam 203. The filter screen 201 is arranged at the bottom of the guide plate 104, and the two sides of the filter screen 201 are slidably connected to the inner walls of the two sides of the chassis 101. The motor 202 is fixedly installed on the outer wall of one end of the chassis 101 through a mounting plate. One end of the cylindrical cam 203 is rotatably connected to the outer wall of one end of the chassis 101 through a mounting bearing. The other end of the cylindrical cam 203 is driven by the output end of the motor 202 through a gear set. One end of the filter screen 201 is fixedly connected to a connecting rod 204, one end of the connecting rod 204 is penetrated through the box wall at one end of the chassis 101 and extends to the outside, and one end of the connecting rod 204 is fixedly connected to a moving block 205, and the moving block 205 is connected to the cylindrical cam 2 03 is slidably connected with the wheel groove on the surface, and a collecting bin 206 is provided at the bottom of the filter 201. Excess paint will pass through the placement rack 103 and flow into the filter 201 through two guide plates 104 for filtration. The motor 202 is driven by an external control mechanism, and the motor 202 drives the cylindrical cam 203 to rotate through a gear set. The cylindrical cam 203 reciprocates in and out of the box wall at one end of the chassis 101 through the wheel groove and the moving block 205 connecting rod 204, thereby driving the filter 201 to reciprocate in the inner cavity at the bottom of the chassis 101, preventing the paint from falling on one position on the filter 201 all the time, causing the filter to be blocked and affecting the filtering effect of impurities. The filtered paint flows into the collecting bin 206 for reuse.

[0025] Further, such as Figure 3 As shown, sliders 2011 are provided on both sides of the filter 201, and slide grooves 1011 adapted to the sliders 2011 are opened on the inner walls of both sides of the chassis 101 relative to the positions of the sliders 2011. The filter 201 and the chassis 101 are limited and slidable through the sliders 2011 and the slide grooves 1011, and the connecting rod 204 reciprocates in and out of the box wall at one end of the chassis 101, thereby driving the filter 201 to slide at the bottom of the chassis 101 through the sliders 2011 and the slide grooves 1011.

[0026] Furthermore, if Figure 3 As shown, the slider 2011 is gradually inclined upward along the side of the filter 201 toward the outside of the filter 201. Since paint has a strong adhesion tropism, the slider 2011 is inclined upward and the design of the slide groove 1011 can prevent the paint from flowing into the slide groove 1011, thereby preventing the slider 2011 from adhering to the slide groove 1011 and affecting the movement of the filter 201.

[0027] It is worth noting that if Figure 2 As shown, the length of the filter screen 201 is greater than the maximum vertical distance between the bottom end of the guide plate 104 and the inner walls at both ends of the chassis 101 , ensuring that the paint can always flow to the filter screen 201 through the guide plate 104 .

[0028] It is worth noting that Figure 1 , Figure 2As shown, the top of the collecting bin 206 is open, and the outer wall of the collecting bin 206 is connected to the inner wall of the bottom of the chassis 101, ensuring that the filtered paint can always flow into the collecting bin 206 during the movement of the filter screen 201.

[0029] Working principle: When the utility model is used, the metal plate is first placed on the placement rack 103, and the paint spraying mechanism 102 is driven by an external control mechanism to spray paint on the surface of the metal plate. The excess paint will pass through the placement rack 103 and flow into the filter disc 201 through the two guide plates 104 for filtration. The motor 202 is driven by the external control mechanism, and the motor 202 drives the cylindrical cam 203 to rotate through the gear set. The cylindrical cam 203 reciprocates in and out of the box wall at one end of the chassis 101 through the wheel groove and the moving block 205 connecting rod 204, thereby driving the filter 201 to slide reciprocatingly in the inner cavity at the bottom of the chassis 101 through the slider 2011 and the slide groove 1011 to limit the position, constantly changing the position of the paint flowing to the filter 201, preventing the paint from falling on a position on the filter 201 all the time, causing the filter to be blocked, affecting the filtering effect of impurities, and the filtered paint flows into the collection bin 206 for reuse.

[0030] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
