Description

Technical Field

[0001] The utility model relates to the field of paint spraying devices, in particular to a paint spraying device for a tricycle canopy frame. Background Art

[0002] A tricycle is a means of transportation modified from a bicycle. It can carry people or goods. It is a combination of a rickshaw and a bicycle. During the production process, the tricycle needs to be painted. Strictly following the painting process and operating procedures can ensure that the painting effect is good and lasting.

[0003] A Chinese patent document with authorization announcement number CN220072080U proposes an electrostatic painting device for the surface of a tricycle, including an electrostatic spray paint room and an electrostatic generator. A conveying assembly is arranged at the bottom of the electrostatic spray paint room, and a fixed seat is arranged below the conveying assembly. The fixed seat is located inside the support frame, and three-axis cylinders are symmetrically arranged at both ends of the fixed seat. A lifting plate is fixedly connected to the output end of the three-axis cylinder, and a bearing is fixedly connected to the center of the lifting plate. A rotating shaft is rotatably connected inside the bearing, and a worm gear is circumferentially fixedly connected to the end of the rotating shaft close to the fixed seat, and a worm is meshed on the worm gear. A rotating motor is fixedly connected to one end of the worm gear, and the rotating motor is fixedly arranged on the lifting plate, and a rotating plate is fixedly connected to the end of the rotating shaft away from the fixed seat.

[0004] In the above application, although the workpiece can be controlled to rotate when being transported to the atomizing nozzle inside the electrostatic spray booth so that the workpiece can receive paint without blind spots, the method of placing the workpiece on the chain is not suitable for the tricycle canopy frame. Since the tricycle canopy frame is generally rod-shaped, placing the tricycle canopy frame on the chain will cause the canopy frame to have a large blind spot for spraying paint. Utility Model Content

[0005] In view of the problems existing in the background technology, a three-wheeled vehicle canopy frame painting device is proposed.

[0006] The utility model provides a three-wheeled tent frame painting device, comprising a bracket. A hanging conveyor belt is arranged on the bracket; a plurality of hangers for transporting the tent frame are slidably arranged on the hanging conveyor belt; the lower end of the hanger is rotatably connected to a rotating shaft; a gear is coaxially connected to the rotating shaft, and a hook is connected to the lower end. A spraying room is arranged on both sides of the hanging conveyor belt. An in-position sensor is arranged on the inner wall of the spraying room to sense the tent frame. A positioning member is arranged below the spraying room to position the tent frame. A rotating member is arranged on the inner wall of the spraying room to cooperate with the gear to drive the tent frame to rotate. And a spraying member is arranged on one side of the spraying room to spray paint on the tent frame.

[0007] Preferably, the positioning member comprises a telescopic mechanism disposed below the paint spraying room; a driving mechanism 1 is disposed at the upper end of the telescopic mechanism; and a driving end of the driving mechanism 1 is connected to the positioning platform.

[0008] Preferably, the rotating member includes connecting plates symmetrically arranged on the inner wall of the paint spraying chamber; a threaded rod is rotatably connected between the connecting plates on both sides; one end of the threaded rod is connected to a driving mechanism 2, and a rack meshing with the gear is also threadedly connected thereon.

[0009] Preferably, a limit rod is further provided on the inner wall of the paint spraying room; the limit rod is opposite to the position of the rack in the paint spraying room, and the side of the limit rod close to the gear abuts against the gear.

[0010] Preferably, the paint spraying part comprises a paint canister arranged on the paint spraying room; the paint canister is connected to a delivery pump; a plurality of spray heads are evenly arranged on a side of the delivery pump facing the tent frame.

[0011] Preferably, the in-place sensor and the suspension conveyor belt, the telescopic mechanism, the driving mechanism 1, the driving mechanism 2, and the conveying pump are all connected by telecommunication.

[0012] Preferably, the in-place sensor, the positioning member and the delivery pump are all located on the same vertical plane.

[0013] Compared with the prior art, the utility model has the following beneficial technical effects:

[0023] like Figure 1-6 As shown, the utility model proposes a three-wheeled canopy frame painting device, comprising a bracket 1, a spray paint room 8, an in-position sensor 9, a positioning member 10, a rotating member 11 and a spray paint member 12. A suspension conveyor belt 2 is provided on the bracket 1; a plurality of hangers 3 for transporting the canopy frame 7 are slidably provided on the suspension conveyor belt 2; the lower end of the hanger 3 is rotatably connected to a rotating shaft 4; a gear 5 is coaxially connected to the rotating shaft 4, and a hook 6 is connected to the lower end. The spray paint room 8 is arranged on both sides of the suspension conveyor belt 2. The in-position sensor 9 is arranged at the inner wall of the spray paint room 8 to sense the canopy frame 7. The positioning member 10 is arranged below the spray paint room 8 to position the canopy frame 7. The rotating member 11 is arranged at the inner wall of the spray paint room 8, and cooperates with the gear 5 to drive the canopy frame 7 to rotate. The spray paint member 12 is arranged on one side of the spray paint room 8 to spray paint on the canopy frame 7.

[0024] Further explanation, the positioning member 10 includes a telescopic mechanism 101 arranged below the spray booth 8, the telescopic mechanism 101 is an electric telescopic rod; the upper end of the telescopic mechanism 101 is provided with a driving mechanism 102, the driving mechanism 102 is a motor; the driving end of the driving mechanism 102 is connected to a positioning platform 103. The lower end of the tent frame 7 can be pressed against the tent frame 7 to position the tent frame 7, so as to prevent the tent frame 7 from shaking left and right during the spraying process, resulting in uneven spraying.

[0025] Further explanation, the rotating member 11 includes a connecting plate 111 symmetrically arranged on the inner wall of the spray booth 8; a threaded rod 112 is rotatably connected between the connecting plates 111 on both sides; one end of the threaded rod 112 is connected to a second driving mechanism 113, which is a motor, and a rack 114 meshing with the gear 5 is also threadedly connected thereto. The canopy frame 7 can be driven to rotate, so that the paint can be evenly sprayed to various parts of the canopy frame 7, preventing the canopy frame 7 from having a dead angle on the side away from the spray paint member 12 that cannot be sprayed by the paint.

[0026] Further, a limiting rod 115 is provided on the inner wall of the spray booth 8; the limiting rod 115 is opposite to the position of the rack 114 in the spray booth 8, and the side of the limiting rod 115 close to the gear 5 abuts against the gear 5. The rack 114 and the limiting rod 115 can clamp the gear 5 from both sides to prevent the gear 5 from not being able to rotate with the movement of the rack 114.

[0027] Further, the paint spraying member 12 includes a paint can 121 disposed on the paint spraying room 8; the paint can 121 is connected to a delivery pump 122; and a plurality of spray heads 123 are evenly disposed on the side of the delivery pump 122 facing the tent frame 7, so that the tent frame 7 can be evenly sprayed with paint.

[0028] Further, the in-place sensor 9 is connected to the hanging conveyor belt 2, the telescopic mechanism 101, the driving mechanism 1 102, the driving mechanism 2 113, and the conveying pump 122. When the in-place sensor 9 senses the tent frame 7, the hanging conveyor belt 2 can be driven to stop operating, and the telescopic mechanism 101, the driving mechanism 1 102, the driving mechanism 2 113, and the conveying pump 122 can be driven to start operating.

[0029] Further, the in-position sensor 9, the positioning member 10 and the delivery pump 122 are all located on the same vertical plane. When the in-position sensor 9 drives the suspension conveyor belt 2 to stop operating and thus the tent frame 7 stops moving, the tent frame 7 just stays above the positioning member 10, and the nozzle 123 can be aligned with the tent frame 7.

[0030] The working principle of the utility model is as follows: when working, first hang the tent frame 7 on the hook 6, then start the hanging conveyor belt 2 to drive the hanger 3 to move along the hanging conveyor belt 2, when the tent frame 7 moves to pass the in-place sensor 9, the in-place sensor 9 senses the tent frame 7 and drives the hanging conveyor belt 2 to stop running, so that the tent frame 7 stops moving. At the same time, the telescopic mechanism 101 will be sensed to extend the telescopic end, so that the upper end of the positioning platform 103 and the lower end of the tent frame 7 are against each other, and the tent frame 7 is positioned to prevent the tent frame 7 from shaking left and right during the painting process, resulting in uneven painting. Then the driving mechanism 2 113 is sensed to drive the threaded rod 112 to rotate, so that the rack 114 moves along the threaded rod 112, and then the gear 5 meshing with the rack 114 rotates, and drives the tent frame 7 to rotate, and the driving mechanism 1 102 will also drive the positioning platform 103 to rotate with the rotation of the tent frame 7. Thereby, the paint can be sprayed evenly to each part of the tent frame 7, and the tent frame 7 is prevented from having a dead angle on one side away from the paint spraying part 12. Meanwhile, the delivery pump 122 is started, and the spray head 123 sprays paint to the tent frame 7, completing the paint spraying process.

[0031] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
