Description

Technical Field

[0001] This utility model relates to a hanger, specifically a hanger for spraying plastic parts. Background Technology

[0002] With the rapid development of the plastics industry and the continuous improvement of plastic performance, plastic parts have been used more widely. Plastic parts are very widely used and are indispensable components in home appliances, automobiles, mobile phones, PCs, medical devices and lighting appliances.

[0003] When spraying plastic parts, a hanger is required. The main function of the hanger is to fix the plastic part on the hanger so that the spraying operation can be carried out evenly. Current plastic part spraying hangers can usually only suspend the plastic part and cannot adjust it during the spraying process, such as flipping it. When dealing with some plastic parts with complex shapes, it is possible that the surface of the plastic part will not be fully sprayed, resulting in poor spraying results. Utility Model Content

[0004] The purpose of this utility model is to provide a hanger for spraying plastic parts, which can adjust the direction of the plastic parts during the spraying process, thereby adapting to the spraying of various complex-shaped plastic parts and making the spraying effect better.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hanger for spraying plastic parts, comprising a support mechanism and a drive mechanism mounted on the support mechanism. The support mechanism includes a fixed frame with a U-shaped design and a side groove provided inside the fixed frame. The drive mechanism includes a motor, a screw connected to the output end of the motor, and a lifting block threaded onto the screw. The drive mechanism also includes a first support block and a second support block. A telescopic member is provided between the lifting block and the first support block. The second support block is mounted on a driven shaft, which is horizontally positioned and both ends of the driven shaft are rotatably connected to the fixed frame. The hanger assembly includes a plurality of spaced outer frames and connecting rods for connecting the plurality of outer frames. A plurality of connecting rods are provided and distributed in the circumferential direction of the outer frames. A crossbeam plate is fixed on one of the outer frames, and a knob is rotatably connected to the crossbeam plate. A steering shaft is fixedly connected to the knob, and a plurality of spaced tow hooks are fixed on the steering shaft.

[0006] Preferably, there are two side slots symmetrical to the fixing frame, and one of the side slots is also provided with an extension slot, with the screw located in the extension slot.

[0007] Preferably, an inner edge groove is provided below the extension groove, and a stabilizing plate is fixed to the lower end face of the lifting block. The stabilizing plate slides into the inner edge groove and fits against the inner wall of the inner edge groove. This allows the stabilizing plate to move up and down within the inner edge groove when the lifting block is raised or lowered, ensuring the stability of the bottom structure of the lifting block.

[0008] Preferably, the drive mechanism further includes a protective housing, and the motor is fixed inside the protective housing, so that the motor is protected by the protective housing.

[0009] Preferably, the telescopic component includes a main cylinder and a secondary cylinder slidably installed inside the main cylinder. A connecting shaft is installed at the ends of the main cylinder and the secondary cylinder that are far apart from each other. The two connecting shafts are respectively set on the lifting block and the first support block. This allows the telescopic component to rotate when the lifting block moves up and down, thereby causing the first support block to rotate the second support block on the driven shaft, thus realizing the rotation of the hanging component and changing the angle of the plastic parts inside the hanging component.

[0010] Preferably, the outer frame is designed in the shape of a square, with one end of the outer frame fixed to the first support block and the second support block respectively; thus, the outer frame can be integrated with the first support block and the second support block.

[0011] Preferably, there are two crossbeams, and the two crossbeams are parallel to each other.

[0012] Preferably, the tow hook includes an attachment rod and a tow bar fixedly connected below the attachment rod. There is an angle between the attachment rod and the tow bar, the value of which is between 80° and 100°. The specific value of the angle is determined according to the shape of the plastic part to be sprayed, so as to facilitate the support of the plastic part to be sprayed.

[0013] Preferably, a crossbar is fixed on the bottom outer frame; thereby preventing the plastic parts inside the outer frame from falling off.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model drives a servo motor to rotate a screw, which in turn rotates the driven shaft, causing the hanger to flip and change the orientation of the plastic parts on the hanger. This makes the direction of the plastic parts when being sprayed more in line with actual requirements, thus facilitating spraying of plastic parts of different shapes and adapting to the spraying work of various complex-shaped plastic parts, resulting in better spraying effect.

[0016] 2. This utility model uses a knob to rotate multiple tow hooks, thereby changing the direction of the attachment rod and the tow rod. This allows the tow hooks to provide good support for plastic parts of various shapes, ensuring that the plastic parts of different shapes maintain relative structural stability during the spraying process, resulting in better spraying results.
