Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for corrugated cardboard printers, and specifically relates to an automatic feeding device for a corrugated cardboard printer. Background Technique

[0002] After retrieval, the Chinese patent publication number is CN114524303B, which discloses an automatic feeding device for a corrugated cardboard printer, including a horizontally arranged printer feeding conveyor belt, a forklift platform arranged on the ground, and a base fixed on the ground. The base is located between the printer feeding conveyor belt and the forklift platform, and a V-shaped material transfer frame is hinged to the top of the base. When this technical solution is in use, after the forklift moves to the forklift platform and places the stacked corrugated cardboard on the receiving plate, the corrugated cardboard is conveyed to the printer feeding conveyor belt for feeding under the cooperation of the V-shaped material transfer frame, the material transfer structure, and the driving structure. However, when this structure is in use, due to the inherent working mode of the printer - that is, only single corrugated cardboard is processed in a single operation, the feeding process is relatively time-consuming. The frequent single-piece processing mode also indirectly increases the operating cost of the device, and also affects the working efficiency of the device. If multiple corrugated cardboard are conveyed at one time, it will cause the corrugated cardboard to stack, resulting in the printer being unable to print the bottom corrugated cardboard, with poor applicability and unable to meet the usage requirements. Therefore, an automatic feeding device for a corrugated cardboard printer is proposed to solve the above-mentioned problems. Content of the Utility Model
