[0002] Electrostatic spraying is a method of making atomized paint particles carry negative charges in a DC high-voltage electric field, and then under the action of the electrostatic field, they fly toward the positively charged sprayed surface in a directed manner and deposit into a uniform and firm coating film. It is widely used in fields such as spraying.

[0003] At present, in order to take into account the portability of small outdoor furniture, most small outdoor furniture is composed of folding frames. When electrostatically spraying small outdoor furniture, the folding frame is driven by a suspension to perform rotary spraying. When spraying, the folding frame is easy to unfold during the rotation process, which not only easily leads to incomplete spraying, but also the sudden increase in the volume of the folding frame and the rotation may cause damage to the internal equipment. At the same time, when the electrostatic spraying equipment is working, the sprayed paint is in a mist form and in a closed space. When taking out the painted materials, the paint particles and the volatile harmful gases in the paint cannot be processed, and the workers are easy to inhale them when taking the materials, which is harmful to their health.

[0004] Therefore, it is particularly important to design an electrostatic spray paint device for outdoor small furniture to solve the above-mentioned defects. Utility Model Content

[0025] First, the front of the paint spray box 1 is rotatably connected to a discharge door 101, and the left and right sides of the paint spray box 1 are rotatably connected to inspection doors 102. The discharge door 101 and the inspection door 102 are fixedly connected to the paint spray box 1 through a lock 103. When electrostatically spraying paint on small outdoor furniture components, the discharge door 101 is opened to take out and discharge materials. The interior of the paint spray box 1 can be regularly inspected through the inspection door 102. During the electrostatic spraying of small outdoor furniture components, the discharge door 101 and the inspection door 102 are closed through the lock 103.

[0026] Furthermore, a reducer 104 is fixedly installed at the bottom of the paint spray box 1 and located in front of the driving motor 4. The driving end of the driving motor 4 is connected to the reducer 104. The reducer 104 and the right end of the roller 3 are fixedly connected with a transmission gear 105. Multiple sets of transmission gears 105 are connected to each other through a synchronous belt 106. When electrostatic painting of small outdoor furniture components is performed, after the small outdoor furniture components are placed in the paint spray roller 5, the driving motor 4 is started to drive the transmission gear 105 to rotate under the deceleration of the reducer 104, and then the two sets of rollers 3 are driven to rotate under the transmission of the synchronous belt 106.

[0027] Then, the left and right ends of the roller 3 are rotatably connected to the paint spray box 1 through the bearing seat 301, and multiple groups of rollers 302 are fixedly connected between the inner side of the roller 3 and the paint spray roller 5. When the two groups of rollers 3 rotate, the paint spray roller 5 is driven to rotate through the multiple groups of rollers 302. The paint spray roller 5 is used to limit the small outdoor furniture components to prevent them from being unfolded and causing damage to the inside of the paint spray box 1, and at the same time cooperate with the nozzle 6 to fully spray paint.

[0028] Furthermore, a feed port is provided on the outer side of the paint roller 5, and a connecting frame 501 is fixedly connected to the outer side of the feed port, and a sealing door 502 is inserted on the inner side of the connecting frame 501. Paint spraying openings 503 are provided at positions on the left and right sides of the paint roller 5 corresponding to the nozzle 6. When the small outdoor furniture components are placed on the inner side of the paint roller 5, the sealing door 502 can be pulled out downward from the inner side of the connecting frame 501, so as to open the feed port and place the small outdoor furniture components on the inner side of the paint roller 5, and then the sealing door 502 is reinserted into the inner side of the connecting frame 501 to close the feed port. During the rotation of the paint roller 5, the nozzle 6 sprays the paint liquid into the inner side of the paint roller 5 through the paint spraying opening 503 to fully spray the outer side of the small outdoor furniture components with paint liquid.

The top ends of the two groups of paint liquid branch pipes 601 are connected through a paint liquid inlet pipe 602. A connector 603 is fixedly installed at the right end of the paint liquid inlet pipe 602 and located outside the paint spray box 1. The paint liquid is introduced into the paint liquid inlet pipe 602 through the connector 603, and then diverted through the paint liquid branch pipe 601 and finally sprayed out through the two groups of relatively installed nozzles 6, so that during the rotation of the paint roller 5, the outer side of the small outdoor furniture component is fully sprayed with paint liquid.

[0030] Finally, the filter assembly 8 includes a filter box 801 fixedly installed on the top of the paint spray box 1, an exhaust fan 802 is fixedly installed at the front end of the filter box 801, an exhaust pipe 803 is fixedly connected to the rear end of the exhaust fan 802, an exhaust pipe 804 is fixedly connected to the top of the exhaust fan 802, an activated carbon filter element 805 and a filter screen 806 are respectively plugged into the rear end of the filter box 801, an air suction hood 807 is fixedly installed at the top of the paint spray box 1, and the top of the air suction hood 807 is connected to the filter box 801 through a ventilation pipe 808. After the outdoor furniture components are painted, they are not taken out immediately. The exhaust fan 802 is started to suck the air inside the paint spray box 1 through the suction hood 807 under the suction force of the exhaust, and is introduced into the interior of the filter box 801 through the ventilation pipe 808. The paint particles are first filtered and blocked by the filter net 806, and then the harmful gases are filtered by the activated carbon filter element 805. After the gas in the paint spray box 1 is purified, the paint spray box 1 is opened to take out the outdoor furniture components, so that the safety of the production process is guaranteed.

[0031] In this embodiment, the implementation scenario is specifically as follows: when electrostatically spraying paint on small outdoor furniture, first open the discharge door 101 to discharge the material, and then pull the sealing door 502 out from the inner side of the connecting frame 501 downward, so as to open the feed port and put the small outdoor furniture components into the inner side of the paint roller 5, and then reinsert the sealing door 502 into the inner side of the connecting frame 501 to close the feed port, and then drive the paint roller 5 to rotate, and use the paint roller 5 to limit the small outdoor furniture components to avoid their unfolding and causing damage to the inside of the paint spray box 1. During the rotation of the paint roller 5, the nozzle 6 sprays the paint liquid into the inner side of the paint roller 5 through the paint spray port 503 to fully spray the paint liquid on the outer side of the small outdoor furniture components. After the painting of the small outdoor furniture components is completed, do not immediately Take it out, start the exhaust fan 802, and suck the air inside the paint spray box 1 through the suction hood 807 under the suction force of the exhaust, and introduce it into the interior of the filter box 801 through the ventilation pipe 808. The paint particles are first filtered and blocked by the filter net 806, and then the harmful gases are filtered through the activated carbon filter element 805. After the gas in the paint spray box 1 is purified, the paint spray box 1 is opened to take out the outdoor furniture components. During the painting process, excess waste liquid will drip to the inside of the material guide tray 2, and finally be exported through the outlet cover 7 for processing. The whole operation process is simple and convenient. Compared with the existing electrostatic paint spraying device, the utility model can improve the overall protection and paint uniformity of the electrostatic paint spraying device for outdoor furniture through design, and can ensure the safety of the production process.
