Problems solved by technology

[0003] At present, plastic spraying generally needs to be carried out manually with a spray gun, and because the spray powder used for plastic spraying is harmful to the human body, it is necessary to be fully armed when spraying plastic manually to protect the safety of the operator during the plastic spraying process, but it will cause spraying. Inconvenient plastic operation, while increasing labor costs on the plastic spraying production line

Embodiment 1

[0033] Such as figure 1 As shown, a plastic spraying system includes a plastic spraying room 14 and a rail conveying line 17, the plastic spraying room 14 has a relative inlet 14a and an outlet 14b, and a plurality of workpieces to be sprayed are hung on the rail conveying line 17, and the guide rail The frame in the conveying line 17 has a transmission chain 171 and a power source (not shown in the figure) that drives the movement of the transmission chain 171. This is the prior art, so it will not be further elaborated in the embodiment of the present invention. 17 runs through the plastic spraying room 14, so that the workpiece to be sprayed enters the plastic spraying room 14 from the inlet 14a, and the plastic sprayed workpiece is transported out from the outlet 14b, realizing the assembly line plastic spraying method.

[0034] combine figure 2As shown, on the frame in the guide rail conveying line 17, a plurality of fixed plates 172 are installed below the drive chain ...

Embodiment 2

[0051] combine Figure 5 As shown, a plastic spraying process is applied to the plastic spraying system described in Embodiment 1, and the guide rail conveying line 17 is in the shape of a circular track, and includes the following steps in turn:

[0052] S1. Clamping: hang the workpiece to be sprayed on the loading area 11 to the lower end of the hook 22 in the hanger assembly 2 on the guide rail conveying line 17 .

[0053] S2. Pretreatment: The workpiece to be sprayed is transported to the shower room 12 through the guide rail conveying line 17, and the degreasing and rust removing agent is sprayed in the shower room 12. The formula is 4% oil and rust removing additive XH-16, 60% Hydrochloric acid (35% concentration) and 36% water are used for degreasing and rust removal to improve the adhesion of the coating.

[0054] S3. Preheating: the workpiece to be sprayed after S2 is transferred to the preheating room 13 through the guide rail conveying line 17, and the workpiece to...

Abstract

The invention discloses a plastic spraying system and a plastic spraying process applying the same, and relates to the technical field of surface treatment. The plastic spraying system and the plasticspraying process solve the problems that for the plastic spraying process in the prior art, the labor cost is high, operation personnel inconveniently carry out operation, and the operation personnelhave the safety risk. According to the technical scheme, the plastic spraying system is characterized by comprising a plastic spraying room and a guide rail conveying line, wherein the guide rail conveying line is provided with a plurality of hanging frame assemblies for allowing workpieces to be subject to plastic spraying to be hung, a spraying box with an opening in the top is arranged in theplastic spraying room, each hanging frame assembly comprises a base frame and a hook which is installed on the corresponding base frame in a telescopic mode and is used for allowing one workpiece to be subject to plastic spraying to be hung, a first driving element for driving the hooks to enable the workpieces to be subject to plastic spraying to be put into/taken out of the spraying box is arranged in the plastic spraying room, and a spray gun with a gun opening facing the center of the spraying box is arranged in the spraying box. According to the system and the process, the effect that a manual plastic spraying mode is replaced by an automatic mode in the plastic spraying treatment is achieved so that on the premise of protecting the safety of operators in the plastic spraying process,the labor cost of a plastic spraying production line can be reduced, and the plastic spraying operation is convenient.

Description

technical field [0001] The invention relates to the technical field of surface treatment, more specifically, to a plastic spraying system and a plastic spraying process using the same. Background technique [0002] Electrostatic spraying of powder coatings is called plastic spraying, and its principle is: the powder coating is adsorbed on the workpiece by using the phenomenon of corona discharge. The process is as follows: the powder coating is fed into the spray gun by means of compressed air from the powder supply system, and a high voltage generated by a high-voltage electrostatic generator is added to the front of the spray gun. When sprayed, charged paint particles are formed, which are attracted to the workpiece with the opposite polarity by the electrostatic force. As the sprayed powder increases, the charge accumulation increases. When it reaches a certain thickness, due to the generation of static electricity Repelling operation, it will not continue to absorb, so ...
