Description

Technical Field

[0001] The invention relates to the technical field of powder spraying, in particular to electrostatic powder spraying equipment for wooden doors. Background Art

[0002] The electrostatic powder coating process includes preheating, powder spraying, curing, and cooling.

[0036] Two bidirectional screw rods 202 are rotatably installed on the platform plate 201, one of which is connected to the motor 1, and the two bidirectional screw rods 202 are connected by a belt 203. The two bidirectional screw rods 202 rotate synchronously, and each bidirectional screw rod 202 is respectively threadedly connected to a powder spraying slide 205, and each powder spraying slide 205 is respectively slidably installed on a vertical rod 204, and the vertical rod 204 is installed on the platform plate 201. A bidirectional screw rod 206 is rotatably installed on each powder spraying slide 205, and the two bidirectional screw rods 206 are connected by a belt three 224. A spray gun positioning frame 208 is slidably installed on each powder spraying slide 205, and an adjustment frame 207 is rotatably installed on each spray gun positioning frame 208.

[0037] A powder spray slide 2 209 is fixedly installed on one of the powder spray slides 1 205, and there are two powder spray slides 209. Another powder spray slide 209 is installed on the platform plate 201. A bidirectional screw 3 211 is rotatably installed in each of the two powder spray slides 209. Each bidirectional screw 3 211 is threadedly connected to a spray gun positioning frame 2 210, and the spray gun positioning frame 2 210 is slidably installed in the powder spray slide 2 209; one of the bidirectional screws 3 211 is connected to a bidirectional screw rod 2 206 through a belt 212, the bidirectional screw rod 206 is connected to the motor 2, and the other bidirectional screw rod 3 211 is connected to the motor 3.

[0038] The straight section on one side of the guide rail is located between the two powder spraying slides 205 , and the powder spraying slide 209 is located between the two powder spraying slides 205 .

[0039] The present invention operates as follows: Spray guns are mounted on the adjustment frame 207, the second spray gun positioning frame 210, and the third spray gun positioning frame 216. The sheet material is preheated and placed on the loading rack 103. A power element drives multiple moving assemblies in the guide rails to intermittently slide within the rails. When the moving assemblies move to the position of the guide plate 102, the mating plate 109 first contacts the inclined section of the guide plate 102, pressing the mating plate 109 downward, compressing the first moving spring 110. Subsequently, the mating plate 109 contacts the straight section of the guide plate 102, and movement ceases when the hook rod 111 moves to the corresponding position of the loading assembly.

[0040] At this time, the hook rod 111 corresponds to the plate opening position on the loading rack 103, and the hydraulic cylinder 105 is started to extend and retract the piston rod to drive the push plate 106 to move. The push plate 106 pushes the two hook rods 111, so that the two hook rods 111 are inserted into the plate opening, and the hook rod 111 drives the cross slide 112 to slide on the moving plate 108, compressing the moving spring 2 113, and then the moving assembly continues to move, and the matching plate 109 contacts the other inclined section of the guide plate 102. The matching plate 109 rises under the elastic force of the moving spring 110, driving the plate to rise, and then the matching plate 109 disengages from the guide plate 102, and the push plate 106 returns to its initial position, and the cross slide 112 returns to its initial position under the elastic force of the moving spring 2 113.

[0041] The hook rod 111 drives the plate to continue moving a preset distance, and the plate stops moving after moving to a preset position between the two powder spraying slides 205. The starting motor 1 drives the bidirectional screw rod 202 to rotate, driving the powder spraying slide 205 to slide on the vertical rod 204. The height of the powder spraying slide 205 is adjusted according to the height of the plate. Then, the adjustment frame 207 is rotated to adjust the angle of the adjustment frame 207 on the spray gun positioning frame 208, thereby adjusting the angle of the spray gun, so that the spray gun is tilted for powder spraying, avoiding uneven spraying caused by obstruction of the hook rod 111. The starting motor 2 drives the bidirectional screw rod 206 to rotate, driving the spray gun positioning frame 208 to move back and forth in the powder spraying slide 205, spraying the front and back sides of the plate.

[0042] Start motor three to drive bidirectional screw three 211 to rotate, and at the same time, bidirectional screw rod two 206 drives another bidirectional screw three 211 to rotate through belt two 212, driving spray gun positioning frame two 210 to move back and forth in powder spraying slide two 209 to spray powder on the top and bottom of the plate.

[0043] After the powder spraying on four sides is completed, the moving component moves a preset distance and stops above the incomplete gear 1 218, and the powder spraying motor 217 is started to drive the incomplete gear 1 218 and the incomplete gear 2 219 to rotate. The incomplete gear 2 219 engages with the rack slide 220 to drive the rack slide 220 to slide, driving the powder spraying gear 221, the powder spraying slide 3 214, and the bidirectional screw rod 4 215 to move, driving the powder spraying slide 213 to slide on the platform plate 201, and the bidirectional screw rod 4 215 slides in the inclined slide groove 223 until the two powder spraying slides 3 214 slide relative to each other to the corresponding positions.

[0044] At this time, the two powder spraying slides 3 214 are respectively located on both sides of the plate. At this time, the bidirectional screw rod 4 215 is in contact with the powder spraying spring 222. At the same time, the powder spraying gear 221 moves to the position where the incomplete gear 1 218 has no tooth structure. Then the incomplete gear 2 219 that continues to rotate is disengaged from the rack slide 220, and the incomplete gear 1 218 that continues to rotate is engaged with the powder spraying gear 221, driving the powder spraying gear 221 to rotate, driving the bidirectional screw rod 4 215 to rotate, and driving the spray gun positioning frame 3 216 to slide back and forth in the powder spraying slide 3 214 to spray powder on the left and right sides of the plate.

[0045] Then the powder spraying motor 217 reverses, the incomplete gear 219 engages with the rack slide 220 to drive the rack slide 220 back to the initial position, and drives the powder spraying slide 3 214 back to the initial position, so that the moving component can pass smoothly, and the powder sprayed plate enters the next process for curing.

[0046] All moving components move at preset distances, so that multiple moving components go through the above process in sequence. For example, when the previous moving component moves to the preset position between the two powder spraying slides 205, the following moving component moves to the corresponding position of the loading component.

[0047] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Those skilled in the art may modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present invention.
