Background technique

At present, in the car cleaning service, non-contact air drying is a commonly used technical method after the vehicle is cleaned. The existing non-contact air drying mainly has two forms: hoisting fan type and gantry type. The hoisting fan type is to fix the fan at a certain position, and realize the air-drying of the vehicle through the moving process of the vehicle. The gantry type uses the reciprocating movement of the gantry structure to achieve the air-drying effect of the vehicle. The wind force and blowing angle are important parameters that affect the air-drying effect. In the two existing non-contact air drying methods, the blowing distance from the surface of the vehicle body is relatively fixed, and the distance is relatively long. The wind force will decrease sharply with the increase of the blowing distance, which reduces the energy density of the blowing, resulting in a decline in the blowing effect. At the same time, the two types of non-contact air drying have a relatively fixed blowing angle, and it is impossible to flexibly adjust the blowing angle to achieve a blowing form that adapts to the streamline of the vehicle, resulting in an unsatisfactory air-drying effect.

The existing non-contact air-drying methods all have high equipment size and cannot adapt to the low space in the site layout, which affects the promotion of automatic air-drying machines.

In addition, limit devices are provided at both ends of the side slide rails 2-4 to prevent derailment of the horizontal side slide table 3 when moving.

Since the lateral sliding table 2 can be displaced along the direction of the lateral fixed table, the horizontal side sliding table 3 can also be displaced in the lateral direction along with the lateral sliding table 2 in the lateral direction.

A fan support 4 is fixed on the horizontal side sliding table 3, which is displaced with the displacement of the horizontal side sliding table 3, and a blower fan 5 is fixed on the fan support 4 to start blowing.

Since the first air pipe 5-2 is a flexible pipe, the wind force and pressure are relatively large during internal ventilation, causing the air pipe to swing in different directions. One end of the stopper 4-1 is fixed on the fan bracket 4, and is located between the fan 5 and the longitudinal support 6, and the swing range and the first air duct 5-2 are limited by the stopper 4-1.
