Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic spraying, in particular to a drying auxiliary device for electrostatic spraying. Background Technique

[0002] Electrostatic spraying refers to a coating method that uses the principle of corona discharge to make the atomized coating carry a negative charge under the action of a high-voltage DC electric field and adsorb on the surface of a positively charged substrate for discharge. The electrostatic spraying equipment consists of a spray gun, a spray cup, an electrostatic spraying high-voltage power supply, etc. After spraying, a drying auxiliary device is needed to dry the coating.

[0003] Most of the drying auxiliary devices for electrostatic spraying on the market cannot evenly dry the surface of the object during drying, resulting in uneven heating of the object and poor drying effect. Moreover, most drying devices require manual hanging of the object in the drying room before drying, and then manual operation is required to enter the drying room before and after drying, with high labor intensity.

[0004] As disclosed in a drying auxiliary device for electrostatic spraying in Chinese Patent CN221230987U, the object is placed on a fixed block, and then the knob is turned. The rotation of the knob drives the bidirectional screw to rotate, and the rotation of the bidirectional screw drives the clamping plate to move left and right in the fixed groove, and the clamping plate moves left and right to fix the object. After spraying, the first motor starts to drive the first screw to rotate, the rotation of the first screw drives the first slider to move left and right in the chute, and the left and right movement of the first slider drives the mounting block to move left and right. When the mounting block moves, it enters the drying box, and then the temperature in the drying box is adjusted through the control panel. The temperature in the box is displayed on the display. After adjusting the temperature, the first heater and the second heater are started, and the current is transmitted to the first heating plate and the second heating plate through the first heating wire and the second heating wire. The heating plate heats the object. During heating, the fan is started, the rotation of the fan drives the fan blade to rotate, and the fan blade rotates to blow the heat flow on the first heating plate to the surface of the object through the through hole to dry the object. During drying, the second motor starts to drive the rotating shaft to rotate, the rotation of the rotating shaft drives the fixed block to rotate, and the rotation of the fixed block drives the object to rotate, and then the second heating plate dries the periphery of the object.

[0027] Please refer to Figures 1-5 , the present utility model provides a technical solution: Embodiment

The heating unit includes a support plate 101, a heating box 102 is fixedly connected to the top surface of the support plate 101, and a heating pipe 103 is installed inside the heating box 102.

[0030] The outer surface of the air hopper 104 is connected to the inner wall of a rectangular hole opened near the right end of the back of the heating box 102. The arc-shaped blocks 108 are installed at the four corners inside the drying chamber 107. One end of the outer surface of the connecting pipe 106 away from the air hopper 104 is connected to the inner wall of a through hole opened in the arc-shaped block 108 at the right end of the front inside the drying chamber 107.

[0031] Through the setting of the drying structure, the arc-shaped blocks 108 installed inside the drying chamber 107 can blow hot air flow inside the connecting pipe 106 to rotate inside the drying chamber 107, so as to perform rotary circulation drying on the surface of the object, thereby ensuring that the paint on the surface of the object is heated more evenly.

[0032] After the object is placed inside the drying chamber 107, the drying chamber 107 is sealed by using the sealing structure. Then, the heating pipe 103 inside the heating box 102 is started to heat, and the rotation of the fan 105 is used to convey the air flow through the inside of the air hopper 104 and the inside of the connecting pipe 106 into the drying chamber 107, so that the air flow is blown from the right side inside the drying chamber 107, and the arc-shaped blocks 108 installed at the four corners inside the drying chamber 107 are used to guide the air flow, so that the hot air flow circulates inside the drying chamber 107, so as to perform rotary circulation drying on the surface of the object and make the object heated more evenly. Embodiment

[0033] On the basis of the first embodiment, the sealing structure includes a workbench 201. A limiting plate 202 is connected to the top surface of the workbench 201. A closing door 203 is connected to the outer surface of the limiting plate 202. A rectangular through hole is opened in the middle of the left side of the closing door 203 near the top, and an observation window 204 is installed inside. A lifting plate 205 is fixedly installed at the top of the middle of the right side of the closing door 203. An electric push rod 206 is connected to the middle of the bottom surface of the lifting plate 205. The bottom surface of the workbench 201 is fixedly connected to the top of the support leg 1. The limiting plate 202 is fixedly installed on the left side of the drying bin 107. The right side of the closing door 203 is slidably connected to the left side of the drying bin 107. The bottom of the electric push rod 206 is connected to the middle of the top surface of the drying bin 107 near the left end.

[0034] The adsorption structure includes a second fan 301. An exhaust pipe 302 is arranged at the top of the second fan 301. Guide rails 303 are installed on the left and right sides inside the exhaust pipe 302. A slider 304 is connected inside the guide rails 303. An adsorption plate 305 is connected to the side of the slider 304 away from the guide rail 303. A push-pull plate 306 is installed on the front surface of the adsorption plate 305. A sealing ring 307 is installed on the back surface of the push-pull plate 306. The second fan 301 is detachably installed inside a rectangular installation hole opened in the middle of the top surface of the drying bin 107. The outer surface of the slider 304 is slidably connected to the inner wall of the convex chute opened in the guide rail 303. The bottom end of the exhaust pipe 302 is fixedly connected to the middle of the top surface of the drying bin 107.

[0035] Through the settings of the sealing structure and the adsorption structure, the electric push rod 206 is used to drive the lifting plate 205 and the closing door 203 to lift, so as to facilitate the opening and closing of the closing door 203, thereby facilitating the sealing and feeding / discharging of the drying bin 107. When heated during drying, the odor and harmful gases emitted from the surface coating of the object are adsorbed by the adsorption plate 305, reducing the harm to the staff.

[0036] After placing the object into the drying bin 107, start the electric push rod 206 to drive the lifting plate 205 to lift. Due to the fixed connection between the lifting plate 205 and the closing door 203, the drying bin 107 can be sealed by the closing door 203. At the same time, the observation window 204 is used to facilitate observing the drying situation of the object inside the drying bin 107. During drying, since the surface coating of the object will emit odor and harmful gases when heated, start the second fan 301 to convey the gas into the exhaust pipe 302. Then, the filler inside the adsorption plate 305 is used to adsorb and process the harmful gases and odor, reducing the harm to the staff's body. The sliding connection between the slider 304 and the guide rail 303 facilitates the replacement of the adsorption plate 305 to ensure the adsorption effect. The sealing ring 307 is used to abut against the surface of the exhaust pipe 302 to ensure the sealing inside the exhaust pipe 302.
