Background

In order to improve the corrosion resistance and appearance effect of the vehicle body and ensure that the vehicle body meets the national standard and the use requirement of users, a plurality of coatings are needed to be coated in the coating process of the vehicle body. A high temperature drying process is required after each coating is applied. On the production line of multiple mixed line production, in order to guarantee the paint film drying effect of large-size vehicle models and vehicle models with complex structures, the drying furnace needs to be adjusted to a higher temperature. However, some car models produced in a collinear way can generate metal plate deformation due to local overheating caused by directly blowing high-temperature air to the car body, and the problem can be solved by adopting a method of shielding part of air openings. The inner cavity drying effect of large-vehicle models and vehicle models with complex structures caused by shielding air ports is poor in actual operation. Two different requirements create a conflict. If the state of the air inlet is adjusted by adopting a vehicle type identification matching electric device, the investment is overlarge, and the failure frequency of the electric element at high temperature is high.

Furthermore, the device is fixed on a wall plate of the drying furnace through a rotating shaft, a baffle plate is arranged on the wall plate, and when the rotating shaft is contacted with the baffle plate, the air outlet is completely shielded by the shielding piece.

Furthermore, a poking sheet is arranged on the rotating rod between the rotating shaft and the heavy hammer.

Furthermore, the rotating rod, the rotating shaft, the shielding piece, the heavy hammer and the shifting piece are made of stainless steel.

A use method of a device for improving the flexibility of a drying furnace comprises the following steps:

s101, when the trolley enters a drying furnace;

s102, the rotating rod is in a vertical state by the gravity of a heavy hammer;

s201, when a large vehicle type or a vehicle type with a complex structure enters a drying furnace;

s202, the vehicle-mounted tool auxiliary tool pokes the poking sheet to enable the rotating rod to deviate from a vertical state.

Compared with the prior art, the invention has the following beneficial effects:

through this device, can realize when passing through different motorcycle types, the automatically regulated function of drying-oven air outlet open-close state has improved the flexibility of drying-oven. And the device has simple structure and can be installed without great modification. The device completely adopts a mechanical structure to realize the automatic adjustment function of the shielding state of the air port, and reduces the use of electrical elements, thereby reducing the probability of failure caused by electrical problems.
