In actual use, in order to facilitate the main body hanging rack to hang below the hanging conveying chain 2, the chain links of the hanging conveying chain 2 are respectively hinged with a hook seat, two ends of two steel wire ropes are respectively provided with a hook, when the main body hanging rack is hung on the hanging conveying chain 2, the hooks on the front ends of the two steel wire ropes are hooked on the hook seats in front, and the hooks on the rear ends of the two steel wire ropes are hooked on the hook seats in the rear.

In this embodiment, a blowing device capable of blowing high-pressure gas to the main body hanger 22 is further disposed at the outlet of the blowing room 21, and the blowing device can reduce the paint powder adsorbed on the main body hanger 22 by the blown air flow. In the present embodiment, the blowing means is three blowing hoses 27 with nozzles connected to the air source, the three blowing hoses 27 do not interfere with the normal operation of the main body hanger 22, and the three blowing hoses 27 blow against the three crossbars 5 at the outlets, respectively, so as to reduce the paint powder adsorbed on the three crossbars 5.

As shown in fig. 3, in this embodiment, an anti-swing frame is disposed at one side of each powder-blocking curtain 25, the upper end of the anti-swing frame is connected with a mounting seat where the powder-blocking curtain 25 is located, the lower end of the anti-swing frame is connected with the lower end of the powder-blocking curtain 25, and the anti-swing frame can limit the lower end of the powder-blocking curtain 25, so that the swing amplitude of the powder-blocking curtain 25 after being stressed can be reduced.

The structure of the anti-swing frame comprises: two double-section connecting rods 28 which are arranged side by side at intervals in the front-back direction, each double-section connecting rod 28 is formed by hinging two anti-swing connecting rods 29 end to end, the upper ends of the two double-section connecting rods 28 are respectively hinged with the front end and the rear end of a mounting seat where the corresponding powder blocking curtain 25 is positioned, and in the embodiment, the mounting seat where the powder blocking curtain 25 is positioned is a base for mounting a retraction device; the lower ends of the two double-section connecting rods 28 are respectively connected with the front lower part and the rear lower part of the corresponding powder-blocking curtain 25, in this embodiment, the lower ends of the two double-section connecting rods 28 are respectively hinged with the front and rear ends of the weight plate 26 on the bottom of the powder-blocking curtain 25, and the two double-section connecting rods 28 are oppositely bent. When the powder curtain 25 is retracted, the two-section link 28 is folded upward.

In the production process, although the powder blocking curtain and the blowing device are arranged, the coating powder attached to the main body hanging frame and the cross rod of the main body hanging frame can be greatly reduced, so that the frequency of plastic stripping treatment is greatly reduced, the production cost and the environmental pollution are reduced, the coating on the wall of the hanging hole on the cross rod 5 is still thicker and thicker along with the increase of the using times of the main body hanging frame, when the cross rod 5 cannot conduct electricity with the hanging tool normally due to the blocking of the coating in the hanging hole, a workpiece cannot be electrified, and thus the workpiece cannot be subjected to electrostatic spraying, at the moment, the main body hanging frame still does not need to be integrally subjected to plastic stripping treatment to remove the coating, the frequency of plastic stripping treatment can be further greatly reduced by only replacing the cross rod 5, the production cost and the environmental pollution are further greatly reduced, and the processing cost of the cross rod 5 is lower, and the coating in the hanging hole can be removed by reaming the hanging hole on the cross rod 5, so that the cross rod 5 can be used again, the operation is simple and labor-saving, and the environmental pollution is also greatly reduced.
