Description

Technical Field

[0001] The utility model relates to the technical field of packaging devices, in particular to a packaging device for annular lamp tubes. Background Art

[0002] The existing ring-shaped light tubes are transported through the assembly line during production. When the ring-shaped light tubes are packaged, the light tubes need to be placed in a box with a ring groove.

[0003] Publication No. CN112340095A discloses a ring-shaped tube packaging device for LED lamps, comprising a transmission device and a tube. The transmission device is provided with a feeding mechanism, a blanking mechanism, and a pressing mechanism. The feeding mechanism comprises a No. 1 fixed frame, a rotating rod, a motor, a fixed plate, a limiting sleeve, a fixed rod, a bracket, a limiting ring, a rotating frame, a limiting disk, a No. 1 connecting frame, a No. 2 connecting frame, and a No. 1 electric telescopic rod. When the transmission device drives its lower packaging box to move to the feeding mechanism, its No. 1 electric telescopic rod opens, forcing its limiting ring to rotate on the fixed rod. As the limiting ring rotates, it pulls its limiting block on the No. 4 connecting frame via a pull rod, thereby separating the limiting block from its limiting disk. The weight of the tube forces the rotating frame to rotate, causing the tube to detach from the rotating frame and fall into the lower packaging box. Subsequently, the No. 1 electric telescopic rod is extended and retracted, causing the limiting block to reengage and press the limiting disk. However, this patent still has the following problems in actual use:

[0004] During use of the above-mentioned device, the lamp tubes need to be manually placed in batches into specific positions. Since the friction of the ring-shaped lamp tubes is low, the stacked lamp tubes are not easy to place. Finally, the device requires extra care when adding lamp tubes, and the operation is relatively inconvenient. The existing operation of placing the lamp tubes into the lower packaging box is basically manual filling, and the simple repetitive operation leads to increased labor costs.

[0005] A packaging device for a ring-shaped light tube is proposed to solve the above problems. Utility Model Content
