Description

Technical Field

[0001] This utility model relates to the technical field of a double-sided powder coating equipment for pads, specifically a double-sided powder coating equipment for pads. Background Technology

[0002] The double-sided powder coating equipment for pads is an industrial device specifically designed for automated powder coating on both sides of a workpiece. Its core function is to uniformly cover both sides of the workpiece with powder coating through electrostatic spraying technology, combining high efficiency, energy saving and environmental protection. Therefore, we have made improvements to this and proposed a double-sided powder coating equipment for pads.

[0003] Based on the above, the inventors discovered the following problem: the nozzles of existing double-sided powder coating equipment are located on opposite sides of the spray booth, so two drive systems are required to drive the movement of the nozzles during use, which is costly. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a double-sided powder coating equipment for a pad, comprising a suspended conveyor line and a spray booth. The suspended conveyor line passes through the spray booth, and several mounting blocks are installed on the conveyor chain of the suspended conveyor line. A sleeve is installed at the bottom of each mounting block, and a rotating component is installed inside the sleeve. A gear is installed at the bottom of the rotating component, and a first connecting plate is installed at the bottom of the gear. A pair of hooks are installed at the bottom of the first connecting plate. A pair of spiral grooves and a pair of straight grooves are formed on the surface of the rotating component. The two ends of the straight grooves are respectively connected to the starting and ending ends of the pair of spiral grooves. A second connecting plate is installed on the inner wall of the spray booth, and a rack is installed at one end of the second connecting plate. The rack matches the gear.

[0006] In a preferred embodiment of this invention, the thickness of the gear is greater than the thickness of the rack.

[0007] As a preferred embodiment of this utility model, a spray gun is installed in the spray booth via a drive mechanism.

[0008] As a preferred technical solution of this utility model, the driving mechanism includes a motor installed on the top of the spray booth, the output end of the motor extending into the spray booth to install a lead screw, the lead screw passing through a connecting rod, and two sets of spray guns installed on the surface of the connecting rod, the two sets of spray guns being distributed on both sides of the second connecting plate.

[0009] As a preferred embodiment of this utility model, a pair of guide rods are installed inside the spray booth, and the guide rods pass through the connecting rod.

[0010] As a preferred embodiment of this utility model, a protective shell is installed on the top of the spray booth, and the motor is located inside the protective shell.

[0011] As a preferred embodiment of this utility model, the sleeve and the mounting block are detachably connected.

[0012] The beneficial effects of this utility model are:

[0013] 1. This type of double-sided powder coating equipment for a coating pad utilizes a combination of mounting blocks, sleeves, rotating parts, gears, a first connecting plate, hooks, spiral grooves, straight grooves, protruding blocks, a second connecting plate, racks, and a drive mechanism to achieve pad rotation. This eliminates the need for two sets of spray guns on one side of the spray booth's inner wall; only one drive mechanism is required, reducing manufacturing costs. Attached Figure Description

[0023] Preferred embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0024] Example: Figure 1-4 As shown, this utility model discloses a double-sided powder coating equipment for a pad, comprising a suspended conveyor line 1 and a spray booth 2. The suspended conveyor line 1 passes through the spray booth 2. Several mounting blocks 3 are installed on the conveyor chain of the suspended conveyor line 1. A sleeve 4 is installed at the bottom of the mounting block 3. A rotating component 5 is installed inside the sleeve 4. A gear 6 is installed at the bottom of the rotating component 5. A first connecting plate 7 is installed at the bottom of the gear 6. A pair of hooks 8 are installed at the bottom of the first connecting plate 7. A pair of spiral grooves 9 and a pair of straight grooves 10 are formed on the surface of the rotating component 5. The two ends of the straight grooves 10 are respectively connected to the starting and ending ends of the pair of spiral grooves 9. A second connecting plate 12 is installed on the inner wall of the spray booth 2. A rack 13 is installed at one end of the second connecting plate 12. The rack 13 matches the gear 6.

[0025] The thickness of the gear 6 is greater than the thickness of the rack 13.

[0026] The spray booth 2 is equipped with a spray gun 15 via a drive mechanism 14.

[0027] The drive mechanism 14 includes a motor 1401 installed on the top of the spray booth 2. The output end of the motor 1401 extends into the spray booth 2 and a lead screw 1402 is installed. The lead screw 1402 passes through a connecting rod 1403. Two sets of spray guns 15 are installed on the surface of the connecting rod 1403. The two sets of spray guns 15 are distributed on both sides of the second connecting plate 12.

[0028] The spray booth 2 is equipped with a pair of guide rods 16, which pass through the connecting rod 1403. The guide rods 16 can limit the movement of the connecting rod 1403.

[0029] The top of the spray booth 2 is equipped with a protective shell 17, and the motor 1401 is located inside the protective shell 17.

[0030] The motor 1401 can be protected by using the protective shell 17.

[0031] The sleeve 4 and the mounting block 3 are detachably connected.

[0032] Working Principle: In use, this double-sided powder coating equipment for pads begins by manually or using a robotic arm to suspend the pad to be powdered on the hook. Then, the suspension conveyor line 1 is started, moving the mounting block 3 and consequently the pad. Once the pad enters the spray booth 2, the spray gun 15 starts the motor 1401. The motor 1401 rotates the lead screw 1402, which in turn moves the connecting rod 1403, thus moving the spray gun 15 and powder coating the pad. As the mounting block 3 moves, when the gear 6 below it contacts the rack 13, it rotates the rotating component 5. With the cooperation of the protrusion 11 and the spiral groove 9, the rotating part 5 will rise. When the protrusion 11 slides to the straight groove 10, the rotating part 5 will fall under the gravity of the pad. It should be noted that the length of the rack 13 can allow the gear 6 to rotate 180 degrees. Since the thickness of the gear 6 is greater than the thickness of the rack 13, the rotating part 5 can continuously mesh with the rack 13 when it rises. At this time, the pad rotates 180 degrees, and the second set of spray guns 15 can spray the other side of the pad. Through the above design, the pad can be flipped, so there is no need to install two sets of spray guns 15 on one side of the inner wall of the spray booth 2. Only one drive mechanism 14 is needed to drive it, which reduces the manufacturing cost.

[0033] Those skilled in the art should understand that the above description of the embodiments of the present invention is only intended to illustrate the beneficial effects of the embodiments of the present invention, and is not intended to limit the embodiments of the present invention to any of the examples given.

[0034] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
