Technical Field
[0001] This utility model relates to the field of luggage technology, specifically a spraying device for processing luggage handles. Background Technology
[0002] Bags and luggage are a general term for all kinds of bags used to carry things, including general shopping bags, handbags, clutches, wallets, backpacks, shoulder bags, shoulder bags, waist bags, and various types of suitcases. The materials used for bags and luggage are also more diverse, including genuine leather, PU, polyester, canvas, cotton and linen, etc. After 20 years of rapid development, China's bag and luggage industry now accounts for more than 70% of the global market share. China's bag and luggage industry has achieved a dominant position in the world, not only as the world's manufacturing center but also as the world's largest consumer market. In the bag and luggage production process, the handle is a very important part.
[0003] Among the existing technologies, the patented announcement number CN218223135U discloses a spraying device for processing luggage handles, which includes a base plate, a worktable, a first side plate and a second side plate. The worktable is provided above the base plate, and a slider is provided at the bottom of the worktable. A slide rail is installed on the top of the worktable, and the slider is slidably connected inside the slide rail. The first side plate is fixedly connected to the top of the worktable, and the second side plate is fixedly connected to the top of the worktable. A turntable is provided on the inner side of the first side plate, and a plug rod is connected to the side of the turntable by an inlay method.
[0004] The existing technology has shortcomings. The existing equipment requires manual fixing of the pull rod each time it is sprayed, and then it is removed from the equipment after spraying. The operation is cumbersome and the production efficiency is low. At the same time, the dust on the pull rod of the bag will reduce the quality of the spraying during the spraying process. To address these issues, we propose a spraying device for processing bag pull rods. Utility Model Content
