The handle 9 is convenient for moving the dust box 22.

[0026] As a further implementation scheme of the above technical scheme: the top end of the second scraper 7 is fixedly connected to the bottom end of the two first scrapers 5 respectively, and the bottom end of the second scraper 7 fits with the bottom end inside the heating box 1, so that the first scraper 5 is convenient for scraping off the paint on the surface of the heating resistor 6.

[0027] As a further implementation scheme of the above technical scheme: one end of the reciprocating screw 3 is rotatably connected to the other side of the heating box 1, and a limit rod 10 is fixedly provided inside the heating box 1.

[0030] During specific implementation: the bonded gold wire body 11 is passed through the heating box 1 and the limiting tube 12, and then the bonded gold wire body 11 is fixed on the rotating roller. When the coating of the bonded gold wire body 11 is completed, the bonded gold wire body 11 is driven to move by the rotating roller, so that the bonded gold wire body 11 with the coating completed enters the interior of the heating box 1, and the heating resistor 6 is started. The heating resistor 6 heats the bonded gold wire body 11, and the water vapor is discharged through the exhaust hole at the top of the heating box 1. When a lot of coating is accumulated on the bottom end of the heating box 1 and the surface of the heating resistor 6, the motor 2 is started, and the transmission shaft of the motor 2 drives the reciprocating screw 3 to rotate, thereby driving the moving block 4 to reciprocate, thereby driving the first scraper 5 and the second scraper 7 to reciprocate, and the coating adhered to the surface of the heating resistor 6 is scraped off by the first scraper 5, and the coating at the bottom end of the inside of the heating box 1 is scraped off by the second scraper 7, and the first scraper 5 is raised by the limiting rod 10.

When the heating resistor 6 heats the bonding gold wire body 11, the fan 18 is started, and the fan 18 generates suction, so that the outside air enters the fan 18 through the air inlet pipe 19, and then the fan 18 discharges the air into the outlet pipe 15 through the exhaust pipe 17, and the exhaust hopper 16 increases the air outlet range of the outlet pipe 15, and the outlet The air in the air pipe 15 is discharged into the heating box 1, thereby facilitating the air flow speed in the heating box 1, accelerating the heat exchange speed between the air near the bonding gold wire body 11 and the air far away from the bonding gold wire body 11, and starting the motor 2. The motor 2 drives the reciprocating screw rod 3 to rotate, thereby driving the moving block 4 to reciprocate, thereby driving the fixed seat 14 to reciprocate, thereby driving the air outlet pipe 15 and the exhaust bucket 16 to reciprocate, so that the exhaust range of the air outlet pipe 15 is further increased, thereby facilitating the uniform temperature in the heating box 1, thereby further improving the drying speed of the coating on the surface of the bonding gold wire body 11.
