Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, and in particular to a spraying device for a plastic box. Background Technology

[0002] In existing technologies, plastic boxes are transparent folding boxes, cylinders, hinged boxes, tote bags, hanging tags, and other related plastic products made of materials such as PVC / PET / PP / PS. They can achieve printing effects such as UV offset printing, screen printing, hot stamping (gold / silver), and matte finishes. During the spraying process, plastic boxes typically require 2-3 coats to ensure even coating adhesion, adequate thickness, and a smooth appearance.

[0003] A search revealed a Chinese patent application with patent number 202420115989.X, which discloses a multi-angle automatic spraying device based on a plastic knob cover. The device comprises a hollow column, a cuboid box, a fixing mechanism, and the hollow box itself. The knob cover to be processed is fitted onto the outside of the cuboid box. Rotating the first rotating cap in the fixing mechanism drives the second rotating column through the meshing of two spur gears. The first rotating column then rotates through the meshing of bevel gears. Two moving plates, connected by a connecting plate, push two arc-shaped push plates away from each other and press against the inner ends of the knob cover, thus fixing it in place. The device offers good stability, simple and convenient operation, and rapid adjustment, facilitating spraying. While this device can achieve comprehensive spraying, it is not suitable for repeated spraying of materials due to the lack of necessary auxiliary drying structures during the spraying process. It is more suitable for materials requiring only a single spraying. Utility Model Content

One of the extended ends of the transmission threaded rod 4 is fixedly connected to the output shaft of the servo motor 7 through a coupling. The servo motor 7 drives the transmission threaded rod 4 to rotate at low speed.

[0030] The outer wall of the transmission threaded rod 4 is threaded with a movable base 22, and the guide slide rod 5 passes through the movable base 22 and is slidably connected to the movable base 22. Multiple movable track wheels 23 are equidistantly mounted on the bottom of both sides of the movable base 22. The bottom end of the movable track wheel 23 is equipped with a matching track 24, which is welded to the top of the bearing base 1.

[0031] The cooperation of the movable base 22, guide slide rod 5, movable track wheel 23, mating track 24, and limiting side plate 2 enables the transmission threaded rod 4 to stably drive the movable base 22 to make low-speed and uniform displacement, ensuring the stability of the movable base 22 during the displacement process.

[0032] A load-bearing connecting plate 20 is fixedly installed on the top of the mobile base 22. A mounting sleeve 25 is welded to the top of the load-bearing connecting plate 20.
