Description

Corrugated paper forming device, adsorption force enhancing device and air suction width adjusting method Technical Field The invention relates to the technical field of corrugated paper production, in particular to a corrugated paper forming device, an adsorption force enhancing device and an air suction width adjusting method. Background The corrugated paper forming is a key process in a corrugated board production line, and the core of the corrugated paper forming is that the core paper is accurately formed on a corrugated roller and firmly attached to the surface paper. In order to ensure that the formed corrugated paper can be stably attached to the surface of the corrugated roller for shaping in high-speed operation, a vacuum adsorption technology is commonly adopted in the industry. Specifically, an air suction cover is arranged on one side of the corrugated roller, and a negative pressure area is formed between the air suction cover and the surface of the corrugated roller through external vacuum equipment, so that corrugated paper is tightly adsorbed on the ridges of the corrugated roller, and subsequent gluing and compounding are completed. In view of the above adsorption requirements, various optimization schemes have been proposed in the prior art. For example, chinese patent publication No. CN208410924U discloses a vacuum adsorption system of a corrugating machine. According to the system, the air suction cover is arranged on the side of the corrugated roller, and negative pressure is generated by the vacuum pump, so that corrugated paper is attached to the corrugated roller. The design aims at reducing vacuum leakage by optimizing the structure of the air suction cover, adding the paper guide copper sheet and extending the extension plate to the vicinity of the meshing point between the rollers, thereby improving the energy efficiency while ensuring the adsorption effect. However, such prior art suction devices, including the above-described patent solutions, typically have a constant air duct width of the suction hood. This results in a suction hood that can only be adapted to a specific width of corrugated paper production. When the production line is required to be switched to produce corrugated boards with different widths, particularly when the width is switched to the narrow width, the air duct with the fixed width cannot conduct targeted guiding on the air flow, so that the air flow is dispersed, the adsorption force is obviously insufficient in the narrow area, and quality defects such as board collapse, foaming and the like are easily caused. At present, the conventional method for solving the problem is to replace the suction hoods with different widths, but the method not only increases the cost of equipment spare parts, but also is tedious and time-consuming in replacement operation, and seriously affects the production efficiency and flexibility. Therefore, development of a device capable of rapidly adapting to different paper widths, without changing a cover body and capable of dynamically and intensively adsorbing air flow is needed, and the development of the device is a technical problem to be improved in the industry. Disclosure of Invention In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a corrugated paper forming apparatus, an adsorption force enhancing apparatus and an air suction width adjusting method, so as to solve the above-mentioned problems. The adsorption force enhancing device for the corrugated paper forming equipment comprises an air suction cover, wherein the air suction cover is provided with an air suction opening and an air inlet channel communicated with the air suction opening; at least one rotatable adjusting baffle is arranged in the air inlet duct; The adjusting baffle plate can be switched to a blocking state or a conducting state; when in the blocking state, the regulating baffle at least partially blocks the air inlet duct so as to reduce the effective width of the suction inlet for adsorbing corrugated paper; When the air inlet channel is in the conducting state, the adjusting baffle plate enables all areas of the air inlet channel to be communicated with the air suction inlet. Specifically, the adsorption force enhancing device further comprises a driving assembly, wherein the driving assembly is connected with the adjusting baffle and used for driving the adjusting baffle to switch between the blocking state and the conducting state. Specifically, the drive assembly includes: At least one driver, its body is installed outside said induced draft cover through the fixing base; The transmission mechanism is connected between the output end of the driver and the adjusting baffle plate and used for converting the linear motion of the driver into the swing of the adjusting baffle plate. Specifically, the transmission mechanism comprises a swing arm and a connector, one end of the swing arm i
