Description

Technical Field

[0001] This utility model relates to the field of paint recycling technology, specifically to a paint recycling device for a spraying equipment. Background Technology

[0002] In the modern spraying industry, spraying conveyor equipment, as the core conveying carrier, often faces the problem of paint residue and spillage during operation.

[0003] Due to the characteristics of the spraying process, some paint cannot adhere precisely to the surface of the workpiece and instead scatters on the conveyor belt. If this residual paint is not effectively recycled in a timely manner, it will not only waste a large amount of paint resources, increase the company's production costs, and reduce resource utilization, but also, as the conveyor belt continues to operate, the residual paint may fall onto the processing area floor, polluting the production environment and requiring additional manpower and resources for cleaning, thus affecting overall production efficiency. Therefore, a paint recycling device for spraying equipment is provided to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a paint recycling device for spraying equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a paint recovery device for a spraying equipment, comprising a support frame with mounting holes on the front and rear sides, a scraper plate being movably installed inside the support frame, a folded edge being provided at the bottom end of the scraper plate, a paint recovery trough being formed between the folded edge and the lower end of the scraper plate, a discharge port being provided through the rear end of the recovery trough, and a discharge pipe being fixedly installed below the discharge port;

[0006] A triangular feeding tube is fixedly installed at the front end of the folded edge, and a paint circulation and pushing mechanism is provided on the right surface of the folded edge. The paint circulation and pushing mechanism is used to push the paint collected in the recycling tank toward the triangular feeding tube and the discharge port.

[0007] Preferably, the paint circulation and pushing mechanism includes two fixed blocks fixedly installed on the right surface of the folded edge and a forward and reverse servo motor. A screw is rotatably installed between the two fixed blocks. The rear end of the screw is fixedly connected to the output end of the forward and reverse servo motor. A rubber push plate is screwed onto the outer surface of the screw. The rubber push plate is slidably connected to the folded edge, and the outer surface of the rubber push plate is in contact with the inner surface of the recycling tank.

[0008] Preferably, the front and rear right surfaces of the support frame are integrally formed with adapter lugs, and the front and rear surfaces of the scraper are fixedly mounted with rotating shafts, which are rotatably connected to the corresponding adapter lugs.

[0009] Preferably, multiple roller frames are symmetrically fixedly installed on the right surface of the scraper, and a conveying roller is rotatably installed between each pair of corresponding roller frames.

[0010] Preferably, an inclined horizontal plate is fixedly installed inside the support frame, and two arc-shaped rods are fixedly installed on the side of the scraper plate near the inclined horizontal plate. The axis of the arc-shaped rods coincides with the axis of the rotating shaft, and the arc-shaped rods pass through the inclined horizontal plate. Two arc-shaped springs are fixedly installed between the inclined horizontal plate and the scraper plate, and the arc-shaped springs are sleeved on the outside of the corresponding arc-shaped rods.

[0011] Preferably, two inwardly inclined guide ribs are fixedly installed on the right surface of the scraper, and the discharge end of the guide ribs is located in front of the discharge port.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention solves the problem of paint easily polluting the environment by installing a scraper with a recycling trough inside the support frame. The top of the scraper can be attached to the bottom of the conveyor belt to scrape off residual paint. At the same time, two inwardly inclined guide ribs are set on the right surface of the scraper to guide the scraped paint to the recycling trough, so as to avoid paint sliding and dripping and polluting the processing environment, reduce the manpower and material cleaning costs, and solve the problem of paint easily polluting the environment in existing solutions.

[0014] By setting a paint circulation and pushing mechanism at the edge of the scraper, and in conjunction with the dual-path discharge structure of the recycling tank ("discharge pipe + triangular discharge pipe"), the paint circulation and pushing mechanism can drive the rubber pusher to move back and forth in a circular motion. In one cycle, the paint in the recycling tank can be pushed to the two discharge paths respectively, which greatly improves the paint discharge efficiency, avoids paint accumulation in the recycling tank, and solves the problem of low discharge efficiency.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution:

[0021] A paint recycling device for a spraying equipment includes a support frame 1 with mounting holes on both the front and rear sides. The front and rear right surfaces of the support frame 1 are integrally formed with adapter lugs. The front and rear surfaces of the scraper 2 are fixedly mounted with rotating shafts. After the rotating shafts are rotatably connected to the corresponding adapter lugs, the upper end of the scraper 2 is rotatably mounted in the support frame 1. The bottom end of the scraper 2 is provided with an upward-facing folded edge 3. The folded edge 3 and the lower end of the scraper 2 form a paint recycling trough. The rear end of the recycling trough is provided with a discharge port 21. A discharge pipe 211 is fixedly installed below the discharge port 21. The discharge pipe 211 is used for main discharge, and the discharge port 21 is used for auxiliary discharge.

[0022] A triangular feeding pipe 31 is fixedly installed at the front end of the folded edge 3, and a paint circulation pushing mechanism 4 is provided on the right surface of the folded edge 3. The paint circulation pushing mechanism 4 is used to push the paint collected in the recycling tank toward the triangular feeding pipe 31 and the discharge port 21, so that the collected paint is discharged from the triangular feeding pipe 31 and the discharge port 21 and collected in the paint bucket.

[0023] When using, combine Figure 1 Figure 2 and Figure 3 As shown, the support frame 1 is fixedly installed inside the equipment frame of the spraying conveyor 7 using its own mounting holes and external bolts, so that the top of the scraper 2 is attached to the bottom of the conveyor belt of the spraying conveyor 7 to scrape off the paint that is scattered on the conveyor belt during the spraying process. The scraped paint slides down into the recycling tank for collection under the action of the scraper 2 and gravity. Then, the paint circulation pushing mechanism 4 is started to push the recycled paint towards the triangular discharge pipe 31 and the discharge port 21, and finally discharges it into the paint bucket for collection from the discharge pipe 211 below the triangular discharge pipe 31 and the discharge port 21.

[0024] This recycling device is equipped with a support frame 1 with mounting holes, a scraper 2 with a recycling trough inside the support frame 1, and a paint circulation pushing mechanism 4 at the folded edge 3 of the scraper 2. It can scrape off and collect the scattered paint on the conveyor belt, reducing residual waste. At the same time, it adopts a dual-path discharge structure of "discharge pipe + triangular discharge pipe 31", which can make the paint circulation pushing mechanism 4 push the paint to the dual-path discharge structure in one cycle, improving the efficiency of recycling and discharging.

[0025] Meanwhile, relying on the support frame 1 with mounting holes, it can be quickly fixed to the inside of the equipment frame of the spraying conveyor 7 by external bolts. There is no need to make extensive modifications to the equipment. Only the support frame 1 that matches the equipment frame of the spraying conveyor 7 needs to be manufactured. This improves the overall paint recycling rate, resource utilization rate and usage flexibility.

[0026] Combination Figure 2 As shown, the paint circulation pushing mechanism 4 includes two fixed blocks 41 fixedly installed on the right surface of the folded edge 3 and a forward and reverse servo motor 44. A screw 42 is rotatably installed between the two fixed blocks 41. The rear end of the screw 42 is fixedly connected to the output end of the forward and reverse servo motor 44. A rubber push plate 43 is screwed onto the outer surface of the screw 42. The rubber push plate 43 is slidably connected to the folded edge 3, and the outer surface of the rubber push plate 43 is in contact with the inner surface of the recycling tank.

[0027] When the paint in the recycling tank is pushed towards the triangular feeding pipe 31 and the discharge port 21, the forward and reverse servo motor 44 is started to rotate in a forward and reverse cycle within a certain range. This uses the screw 42 to drive the rubber push plate 43 to move back and forth in the recycling tank. When moving forward, the paint in the recycling tank is pushed towards the triangular feeding pipe 31, and when moving backward, the paint in the recycling tank is pushed towards the discharge port 21. In one cycle, the recycled paint can be pushed to the two feeding positions respectively, which can improve the efficiency of paint recycling.

[0028] In addition, such as Figure 2 and Figure 3 As shown, this paint recycling equipment needs to be installed between the spraying conveyor 7 and the conveyor belt 8. To ensure stable conveying and avoid conveying interruption, multiple roller frames 5 are symmetrically fixed on the right surface of the scraper 2. Conveying rollers 51 are rotatably installed between the two corresponding roller frames 5. With the help of the conveying rollers 51, the conveying area between the spraying conveyor 7 and the conveyor belt 8 can be supported and transitioned, effectively ensuring the continuity of the connection between the two conveying devices, and ultimately achieving the goal of preventing conveying interruption.

[0029] In addition, to ensure that the top of the scraper blade 2 can fit against the bottom of the conveyor belt of the spraying conveyor equipment 7, and to ensure that the paint can be scraped off stably, such as Figure 1As shown, an inclined horizontal plate 11 is welded and installed inside the support frame 1. Two arc-shaped rods 6 are welded and installed on the side of the scraper plate 2 near the inclined horizontal plate 11. The axis of the arc-shaped rods 6 coincides with the axis of the rotating shaft, and the arc-shaped rods 6 pass through the inclined horizontal plate 11 and slide to it. Two arc-shaped springs 61 are fixedly installed between the inclined horizontal plate 11 and the scraper plate 2. After the arc-shaped springs 61 are sleeved on the outside of the corresponding arc-shaped rods 6, the extension of the arc-shaped springs 61 can be used to lift the upper end of the scraper plate 2 towards the conveyor belt of the spraying conveyor equipment 7, so that it is close to the bottom of the conveyor belt, ensuring the scraping effect of the paint.

[0030] Finally, after the scraper 2 scrapes the paint off the conveyor belt of the spraying conveyor 7, in order to prevent the paint from sliding out of the scraper 2 and dripping onto the processing area floor, thus polluting the processing environment, two inwardly inclined guide ribs 22 are fixedly installed on the right surface of the scraper 2. The tops of the two guide ribs 22 are respectively located at the front and rear ends of the right surface of the scraper 2, and the discharge end of the guide ribs 22 is located in front of the discharge port 21. The scraped paint can be guided to the recycling tank by the two guide ribs 22, thus avoiding the problem of paint dripping onto the processing area floor and polluting the processing environment.
