Description

Technical Field

[0001] This utility model relates to the field of static electricity removal technology for coated parts, and in particular to a static electricity removal device for coated products. Background Technology

[0002] Before coated workpieces leave the factory, their surfaces need to undergo static electricity removal treatment. Because coated workpieces come in a wide variety of types and shapes, a jet of charged particles is typically used to neutralize the static electricity on the workpiece surface, thus achieving the static electricity removal effect. Simultaneously, the air jet also serves to remove dust.

[0003] Generally, these positively charged ions are generated by a high-voltage ion generator, and the air is dried by adsorbing a desiccant to ensure that the positively charged ions are not neutralized. However, existing equipment does not mix the positively charged ions with the air evenly enough, resulting in an uneven distribution of positively charged ions in the ejected gas, which affects the efficiency of static electricity removal.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0031] Example

[0032] Reference Figures 1 to 6 This is an embodiment of the present invention, which provides an antistatic device for coated products, including a dryer 100 connected to an air pump via a conduit, the dryer 100 being connected in series with an ion high-voltage generator 200 and a spray gun 400 via a conduit, a connector 300 being provided between the spray gun 400 and the conduit, the distance 301-1 between the connector 300 and the channel 301 from the conduit to the spray gun 400 gradually decreasing, and guide strips 302 being provided at equal intervals in the channel 301 to make the airflow in the guide channel 302-1 between adjacent guide strips 302 spiral flow;

[0033] Specifically, the dryer 100 includes a power supply 102, a drying pipe 103, and an air inlet 102a and an exhaust 102b provided on the drying pipe 103. The duct system consists of a first pipe 101, a second pipe 104, a branch pipe 106, and a third pipe 107. The power supply 102 is installed on the outer surface of the drying pipe 103. The two ends of the drying pipe 103 are respectively provided with an air inlet 102a and an exhaust 102b. One end of the first pipe 101 is connected to the air inlet 102a, and the other end is connected to the air pump. The second pipe 104 is connected to the exhaust end 102b at one end and to the diversion rigid pipe 105 at the other end. One end of the diversion rigid pipe 105 is connected to the third pipe 107 at one end and to the spray gun 400 and the third pipe 107 respectively through the first connecting end 300-1 and the second connecting end 300-2 on the connector 300. At the same time, the diversion rigid pipe 105 is also connected to the branch pipe 106. The other end of the branch pipe 106 is connected to the third pipe 107 and the ion high-pressure generator 200 respectively.

[0034] An air pump supplies drying gas (such as air or inert gas) to the inlet 102a of the drying pipe 103 through the first pipe 101. This gas undergoes preliminary drying upon entering the drying pipe 103 to remove moisture and other impurities. After the ion high-voltage generator 200 is activated, it ionizes oxygen and nitrogen molecules in the air using high voltage, forming positively and negatively charged ions. These ionized gases enter the gas flow within the drying pipe 103 through the branch pipe 106 and mix with the third pipe 107, ensuring sufficient ions to neutralize static electricity. The ionized drying gas then exits from the drying pipe 102a. The exhaust gas from the exhaust end 102b of the 3rd pipe enters the split rigid pipe 105 through the second pipe 104, and then the split rigid pipe 105 distributes the gas to multiple paths: part of the gas continues to flow through the third pipe 107, and another part of the gas enters the spray gun 400 through the first connection end 300-1 of the connector 300 for direct purging and static electricity removal of the target object. The branch gas is further mixed with the ion high-voltage generator 200 through the branch pipe 106 to ensure a continuous supply of ionized gas. The spray gun 400 sprays dry gas containing ions, which directly acts on the surface of the object with static electricity to neutralize the static charge.

[0035] When the air pressure supplied by the air pump passes through the dryer 100 and the ion high-pressure generator 200 into the connector 300, the gap 301-1 between the conduit and the channel 301 of the connector 300 to the spray gun 400 gradually decreases. The flow rate of the gas increases as it passes through the connector 300. The guide channel 302-1 between the guide strips 302 at equal intervals in the channel 301 is used to change part of the gas flow path, so that the positively charged particles of the gas are fully mixed with the gas before flowing into the spray gun 400 and being sprayed outward. This greatly ensures that the sprayed gas is fully and evenly mixed with positively charged particles. When the gas is sprayed onto the surface of the coated workpiece, the positively charged particles in the gas are fully neutralized with the negatively charged particles of the coated workpiece.

[0036] It is worth mentioning that the sides 302f of the guide strips 302 intersect at one end to increase the volume of the guide channel 302-1 between adjacent guide strips 302. Increasing the volume of the flow channel 302-1 is beneficial for more positively charged particles to participate in the mixed gas, making the positively charged particles mix more thoroughly.

[0037] It is worth mentioning that the guide strip 302 includes a first section 302a and a second section 302b. The first contact surface 302a-1 of the first section 302a is in contact with the inner wall of the connector 300, and the second contact surface 302a-1 of the second section 302b is separated from the inner wall of the connector 300. The first section 302a and the second section 302b are elastically connected, and the second section 302b is located at one end of the spray gun 400. When the airflow passes through, the first section 302a will oscillate. The oscillation action is equivalent to stirring the gas, which also has the effect of making the positively charged particles mix more fully.

[0038] It is worth mentioning that the guide strip 302 is located in the channel 301 of the connector 300 at one end of the spray gun 400. The distance between the top end 302c and the bottom end 302e of the guide strip 302 gradually increases on both sides 302f, so that the guide channel 302-1 between adjacent guide strips 302 is frustoconical. The airflow enters from the bottom end 302e of the guide strip 302 and flows out from the top end 302c of the guide strip 302. The increasingly narrow channel helps to increase the speed of gas flow out of the guide channel 302-1 and provide a stronger ability to mix gas.
