Technical Field

[0001] The present application relates to the technical field of paint spraying equipment, and in particular to a paint spraying line heating system. Background Art

[0002] Spray painting is a method of applying paint to the surface of an object by using a spray gun with the help of air pressure to disperse the paint into uniform and fine droplets. The heating system of the spray painting line mainly includes a spray painting room and a drying room. In industrial production, after the paint is sprayed, the parts enter the drying room for drying.

[0003] Among them, the paint room includes a paint table, which is provided with a guide rail. Several equidistantly distributed hangers are connected to the guide rails, so that the hangers can move with the guide rails, and the workpieces to be painted are hung on the hangers. Currently common hangers include hooks. The workpieces are hung on the hooks and moved to the paint room through the ground rails for painting. In order to be able to paint the workpiece without dead angles during painting, a rotating motor is provided on the hanger to enable the hanger to rotate.

[0004] Regarding the above-mentioned related technologies, the following defects were found: when spraying paint, the hanger will rotate under the action of the rotating motor. At this time, since the workpiece is hung on the hanger through the hook, the workpiece may be positionally offset when the hanger rotates, which may affect the uniform spraying of paint on the workpiece.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a heating system for a paint spraying line. Figure 1 A painting line heating system includes a support component 1 and an elastic fixing component 2, the support component 1 is connected to the elastic fixing component 2, and the workpiece is fixed on the support component 1 through the elastic fixing component 2.

[0033] Reference Figure 1 and Figure 2 The support assembly 1 includes a support rod 11 and a connecting column 12. One end of the support rod 11 is used to connect to the ground rail. The end of the support rod 11 connected to the ground rail is the lower end of the support rod 11. The connecting column 12 is set at the upper end of the support rod 11. A blocking ring 121 is sleeved on the outer side wall of the connecting column 12. When the connecting column 12 is connected to the support rod 11, the blocking ring 121 slides to the outer side wall of the connecting column 12 near the lower end and abuts against the upper end surface of the support rod 11.

[0034] Reference Figure 2 In order to facilitate the shielding ring 121 to slide up and down on the connecting column 12, a pair of pull hooks 1211 are welded on the outer wall of the shielding ring 121. The pull hooks 1211 are in the shape of a "7", so that the staff can drive the shielding ring 121 to slide up and down on the connecting column 12 by pulling the pull hooks 1211. At the same time, in order to improve the smoothness of the insertion when the shielding ring 121 slides out of the connecting column 12 and is then re-inserted into the connecting column 12, a second chamfer 122 is integrally formed on the upper end surface of the connecting column 12.

[0035] Reference Figure 2 and Figure 3The elastic fixing assembly 2 includes a pair of outer support plates 21, a return spring 22 and a pair of anti-slip sleeves 23. The pair of outer support plates 21 are used to fix the workpiece. One end of the pair of outer support plates 21 is hinged at the upper end surface of the connecting column 12, and the end at which the pair of outer support plates 21 are hinged to the connecting column 12 is the lower end of the pair of outer support plates 21. Specifically, a pair of first support ears 123 are welded at the upper end surface of the connecting column 12, and the lower end surfaces of the pair of outer support plates 21 are integrally formed with second support ears 211. The second support ear 211 is aligned with the first support ear 123, and a pin shaft 124 is passed through the first support ear 123. The pin shaft 124 hinges the second support ear 211 with the first support ear 123.

[0036] Reference Figure 1 、 Figure 2 and Figure 3 A pair of outer support plates 21 are provided with positioning grooves 212 at opposite positions on the opposite side walls. The positioning grooves 212 are located at the side walls of the outer support plates 21 away from the hinged connection with the connecting column 12. The two ends of the return spring 22 are respectively welded to the bottom of the positioning grooves 212 on the pair of outer support plates 21, so that the pair of outer support plates 21 can be easily opened under the action of the return spring 22. After being opened, the pair of outer support plates 21 are in a "V" shape.

[0037] Reference Figure 3 In order to improve the stability of the outer support plate 21 when fixing the workpiece, a pair of anti-slip sleeves 23 are respectively mounted on the upper end positions of the pair of outer support plates 21, and a number of evenly distributed protrusions 231 are integrally formed on the outer side walls of the anti-slip sleeves 23, which is beneficial to increase the friction between the outer support plate 21 and the workpiece, thereby improving the stability of the outer support plate 21 when fixing the workpiece.

[0038] Reference Figure 3 In order to prevent the workpiece from getting stuck when it is hung on the outer support plate 21, thereby improving the smoothness of the workpiece when it is hung on the outer support plate 21, a first chamfer 213 is provided at the junction of the two adjacent outer walls of the outer support plate 21. At the same time, in order to enable workpieces of different shapes to be hung on the outer support plate 21, the side wall of the outer support plate 21 facing away from the positioning groove 212 is designed to be an arc surface.

[0039] The implementation principle of a paint line heating system in an embodiment of the present application is: pulling the hook 1211 to move the shielding ring 121 toward the outer support plate 21, and at the same time the shielding ring 121 squeezes the outer support plate 21, so that the pair of outer support plates 21 move in opposite directions. At this time, the workpiece is hung on the pair of outer support plates 21, and the hook 1211 is pulled toward the direction of the connecting column 12 until it abuts the support rod 11. The pair of outer support plates 21 are gradually no longer squeezed by the shielding ring 121. Under the elastic force of the reset spring 22, the outer support plates 21 are stretched outward, so that the upper end of the pair of outer support plates 21 with the anti-slip sleeve 23 is pressed against the inner wall of the workpiece, and the workpiece is fixed to the pair of outer support plates 21.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
